It is distributed in two main parts, a server, where the game actually runs, and clients that connect to the server. The server portion ships with a basic client. This basic client is also available seperately. There are also many third-party clients available. Empire is based on a game written in the late 70s/early 80s by Peter Langston. Since he wouldn't give out the source code, a large reverse engineering/re-coding project was undertaken to create a new version of this game and make the source available for all. Since that time, the Empire code has changed drastically and been re-written numerous times, and none of that original code exists (other than in fond memories) in this code base anymore. There have been various "stages" of Empire development. At this point in time (October, 1998) there have been 5 major stages identified, each with a leading author. They are as follows (with successsive projects building on the projects before it): Dave Pare (mr-frog@smarttouch.com) (UCSD/BSD) Jeff Bailey (bailey@mcs.kent.edu) (KSU (1.04) Distribution of BSD) Thomas Ruschak (ts@ecn.purdue.edu) (Chainsaw) Ken Stevens (KStevens@GlobeandMail.ca) (3.0.x) Steve McClure (ionica@empire.cx) (Wolfpack) It is due to these above people pulling projects together that the Empire server has gotten to where it is today. Empire is copyrighted and released by the 5 people above under the GNU GPL. See the "LEGAL", "LICENSE", "CREDITS" and "README" files for all the related information and legal notices. It is expected that any future projects/authors will amend these files as needed. The source files have been updated to reflect this license, and much erroneous data (such as bogus file headers) has been fixed. Empire source code has always been freely available, with the intent of it always being freely available, it was just never properly copyrighted or licensed until the first release under the GNU GPL (4.2.0) It is our goal to keep Empire source free and available at all times. Also see the "History" info file for a more detailed listing of the history of Empire. Currently (October, 1998), Empire development is being led by the Wolfpack team. You can find them at "http://www.empire.cx" or e-mail "wolfpack@empire.cx". In addition, the people below are recognized as having either given code to the above authors, submitted patches, helped on various aspects of the projects (such as info pages), play tested, submitted bug reports, bounced ideas, etc. Many of the source files have no listed known contributors due to the fact that many, many people contributed anonymously. For those where we knew who contributors were, we listed them in the header. It is hoped that in the future contributors will put their names into this list at the top of the file, and that new files have the same type of header applied to them for future tracking (though obviously it is not required.) We are sure that the list below is most likely incomplete, and anyone who doesn't see your name on the below list, don't be offended, we didn't mean it! Just send us an e-mail letting us know and we'll be more than happy to add you. Also, let us know your latest e-mail address if you'd like it included. --- James Anderson (jwa@k.cs.cmu.edu) Jeff Anton (anton@postgres.berkeley.edu) Markus Armbruster Jeff Bailey (bailey@mcs.kent.edu) Mark Ballinger Jan van Beethoven Paul Byrne Geoff Cashman (cashman@sherrill.kiva.net) Bill Canning Trannie Carter Sean Casey David Davis Aaron Dewell (dewell@greatland.net) Jorge Diaz Drake Diedrich (Drake.Diedrich@anu.edu.au) Yaser Doleh Ed Down Phill Everson (everson@compsci.bristol.ac.uk) Scott Ferguson Robert Forsman (thoth@beach.cis.ufl.edu) Bill Frolick Steven Grady Keith Graham Jim Griffith (griffith@scam.Berkeley.EDU) Steven Grimm (koreth@ucscb.UCSC.EDU) Karl Hagen Doug Hay (Doug_Hay@tsb.ca) Ken Huisman Lewis R.

Copyright (C) 1989, 1991 Free Software Foundation, Inc. 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. NO WARRANTY 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. END OF TERMS AND CONDITIONS How to Apply These Terms to Your New Programs If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.

Congratulations on your choice! See the "LEGAL", "LICENSE", "CREDITS" and "README" files for all the related information and legal notices. It is expected that any future projects/authors will amend these files as needed. For questions and comments, please contact "wolfpack@empire.cx". If you want to build the server, follow the few simple steps below. If you are looking for more information on the files here, options for the server, etc. take a look in the "doc" directory, then follow the steps below to build and start the server. (1) Unpacking the server To unpack the server, simply gunzip and untar the source. (2) Building a server Note that you may not have to build a server. If you received the server in binary format, go to the next step, "Creating the world." To build the server, you need to do the following steps: 1) Get a copy of the source. Since you're reading this, we assume you have done that. 2) Gunzip the source. Again, since you're reading this . . . ;-) 3) edit the build.conf file in this directory, and answer the questions it asks you. 4) type "make depend" to build the dependencies (not required, but helps a lot when you want to recompile something again.) Note: "make depend" doesn't work under NT yet. 5) type "make" to see what architectures are currently supported. 6) choose the architecture that best suits you, and type "make " where is the architecture you want to build. (3) Creating the world (NOTE: If you received a binary, you must edit the included data/econfig file to represent the paths where your data and info directories are.) 1) First, pick the world size you want to use. Once you have chosen a world size, edit the "data/econfig" file (it was either created at build time, or shipped with the binary) and change the WORLD_X and WORLD_Y to be the sizes you want. The default world size is 64x32. IMPORTANT: WORLD_X *MUST* be divisible by 2. In addition, if you change the world size later, you *MUST* re-create the world by running "bin/files" again. 2) Go into the "bin" directory, and run "./files". 3) If you want to create a new world, run "./fairland 10 30" to create a sample world (read the documentation for fairland for more info on it's arguments.) Note that "files" and "fairland" use the world size in the econfig file if it exists in the data directory. If this file doesn't exist, and you don't specify one, it will use the default world size the server was compiled with (Wolfpack binaries ship with a 64x32 world size) You can create an econfig file with default values using the "bin/pconfig" executable. (4) Running the server 1) Run the bin/emp_server executable to start the server. That's it. Once running, you can log on to the server using the emp_client program found in the "bin" directory. The initial deity country name/password is POGO/peter. If you get a "You're not a deity!" message and logged off, check the "data/server.log" file and look at the end for a "NON-AUTH" entry. There should be a "user@host" message in there that failed to log in. The user and host that your system is using may be different than the one you put in your build.conf file. So, enter this new user and host in the auth file, and you should be able to log into the server as a deity now. Note that if you rebuild the server again, the auth file will be overwritten. For more information on options, programs, files and other general hints look in the "doc" directory. The README there describes the files there and what they talk about. For more information or help, send e-mail to "wolfpack@empire.cx" and we'll try to answer if we can. Also check out our web site at "http://www.empire.cx" Have fun! -- The Wolfpack development team... emp4/bin/0040755000225100004300000000000007336035455012326 5ustar johnyjohny-grpemp4/data/0040750000225100004300000000000007336035441012455 5ustar johnyjohny-grpemp4/doc/0040755000225100004300000000000007316206350012313 5ustar johnyjohny-grpemp4/doc/bug-reports0100644000225100004300000000313007220463633014504 0ustar johnyjohny-grp Reporting Bugs Code Correctness What's a bug? Well, if a game program core-dumps under normal conditions, that's definitely a bug. If a player can manufacture game items (circumventing the intended game semantics) then that's a bug too. If you don't agree about an existing semantic, or you don't like the format of a particular command output, that's NOT a bug! If you do have a bug to report, I will only pay attention if I have a chance of fixing it. Bug reports which vaguely describe behavior, e.g., "Sometimes when I run the ship command, it gives me funny output" will be ignored! Bug reports should include game output, stack traces if possible (assuming a core dump is produced), and the major, minor, and patch level of the version you're running. Once you find a bug, try and reproduce it. If you can't, then say so. If you can, say that too. If you can't reproduce it, chances are pretty good that I can't either. If you have a debugger, try running the offending game section under your debugger -- preferably gdb -- and try and locate the area of code responsible. If you can fix the bug and verify the fix, then you can bet that I'll be much more interested in your bug report. Response time is likely to be greater too! Semantics If you want to get into a discussion of game semantics, the best place to do that is rec.games.empire, or your favorite empire-hackers mailing list. Don't send me a bug report about it! Naturally, I hope you don't find any bugs. If you do, go through the above steps, and mail the resulting output to us -- wolfpack@empire.cx emp4/doc/CHANGES0100644000225100004300000010351606624404745013322 0ustar johnyjohny-grpThis file contains a list of patches/upgrades made to the server for a specific version. It also contains the name of the author of that particular code. It may not be complete. *version 2.0 beta 1 release 1* Fixed age.c so reserves degrade normally instead of growing! - Chad Zabel Fixed arch.c - replaced wrapp with what was supposed to be there - Ken Huisman Patched bug in atta.c - a temporary patch that could be done better ( and will be later ) - Ken H. patched bug in lib/commands/mail.c - Dave Pare added patches to make code compile under linux - Ken H. based on linux chain 3 patches by someone else whose name I forget. Note at this time the code *compiles* under linux, but there are still bugs - the server seems to stop taking socket connections or something after someone logs out of the game. fixed a null pointer bug in lib/subs/bigmap.c - Chad Zabel *version 2.0 beta 1 release 2* Patch for exec bug - Chad Zabel *version 2.0 beta 1 release 3* Patch for zepplin bug - Jim Ortlieb Added unixware(svr4.2) specific stuff to arch.c - Doug Hay Changes to h/lwp.h and lib/lwp/lwp.c for thread stack checker - Doug Hay *version 2.0 beta 1 release 4* Modified fairland.c to 1.6.2 and made it so translate_continents is only called when BLITZ is defined - Ken Huisman, Ken Stevens Modifications to lwp.h and arch.c to fix linux threads - Scott Ferguson *version 2.0 beta 1 release 5* Changed version number to 2.0.0 - Ken Huisman fixed unterminated path bug in lib/common/path.c - Scott Ferguson fixed first part of bug described in wish list item c6 ( false resupply ) - Scott Ferguson fixed part of bug described in wish list item t3 ( you have 666 new telegrams bug ) - the bug that tells you you have 1 new telex after just reading it is not fixed - Scott Ferguson *version 2.0 beta 1 release 6* Three letter abbreviations for all ships in ship.c - Chad Zabel the following by Kevin Klemmick: /lib/commands/rea.c // fixed telegram's problem reading '%' /lib/commands/mail.c // ditto for mail and wmail /lib/subs/aircombat.c // New air code and bug fixes /lib/subs/mission.c // New air code and bug fixes /lib/subs/pr.c // new prnf function an bug fixes /lib/subs/paths.c // fixes the getpath() bug. added NEWPAF and HIDDEN to options.h ( commented out for now until testing is complete ) - Ken H. *version 2.0 beta 1 release 7* Fix for fix for exec bug ( lib/player/player.c ) - Chad Zabel fixed minor bug in aircombat.c ( missing quote on line 613 ) - Ken H. *version 2.0 beta 1 release 8* lib/commands/mfir.c Bugfix... in quiet_bigdef, added in a check for forts >60%.

In other words, "kill" fromoutside the server now does the same thing as the deity "shutdown" command does from inside the server. - New player command "strength" calculates sector defense strength (including bonuses from reacting units but excluding air/fort/arty support). I think this command will help newbies set up a defense better. - If you've already compiled once, and you're just working on stuff in the server, then you can now type "compile quick" which will skip dependall, util, and client (and compile in about a quarter the time). The above were all done by Ken Stevens ( I think ) on b2r1b - added "toggle beep" so that you can now play Empire without beeping every time you fire if you so choose (handy for those emergency updates in the department computer room). - "configure" now asks you where you keep your "gnumake". - Fixed a couple of bugs in the configure script - "toggle" flags moved from player to natstr so they're saved - fixed malloc() pointer mismatches to make cc happy - ported "shutdown" to Sun4 - Julian Onions ported his econfig code to Sun4 The above are from b2r1c The following are fixed ( as of b2r1d ): - The infamous "scuttle" bug. Now the owner of units is always set to zero as soon as the unit is created. (By "created" I am referring to when you build 1 plane and ef_extend() creates 49 more -- the owner of all 50 is now initialized to zero.) - A C_INFORM packet was being sent to the client when an announcement was made. Oopsie on my part. Now fixed. - "fortifying" a unit no longer clears the unit's mission. - New script "keepitup" is a modified isempireup except that you don't have to put any info about the game in the file itself, so if you're like me and you have more than one game running, you now only need to keep one script around. b2r1e patch moved files from util into old/util b2r1f contained the following: This patch was submitted by Julian Onions. - General option handling, + BLITZ option changes throughout. There is one new file lib/global/options.c which has the option definitions in. - The following options are now dynamically switchable NOFOOD, BLITZ, EASY_BRIDGES, RES_POP, NEW_WORK, NEW_STARVE, NO_PLAGUE, NEWPOWER ALL_BLEED, DRNUKE SUPER_BARS, NUKEFAILDETONATE, PINPOINTMISSILE - also fix up a stupid test in laun.c, and some reworking of the SHIPNAME (plus a bug fix for Sub launched SHIPNAMES). b2r1g fixed a bug in b2r1f. b2r1h moved a file from old/util back to util b2r1i contained the following: This patch was submitted by Julian Onions. - The following options are now dynamically switchable FUEL, ORBIT, NEUTRON - The new file README/README.config describes how to use the new "econfig" runtime configuration stuff.. - Now when you type "version", you will also get the patchlevel of the code. b2r1j contained the following: This patch was submitted by Kevin Morgan. - xdist and ydist are now in player coordinates (wish list item i2) - emp_client now calls termio until all bytes have been copied into the socket (wish list item x19). b2r1k contained the following: This patch was submitted by Sasha Mikheev. - This patch ports lwp threads to Linux. b2r1l contained the following: This patch was submitted by Julian Onions. - Options NOMOBCOST and GRAB_THINGS are now runtime configurable. b2r1m contained the following from Ken Stevens: WARNING: Although I have heavily tested the code, I'm sure that it still has a significant number of bugs. This patch contains the following changes: - fixed a bug in configure which was not making compile a csh script which resulted in grep not working. - shipdamage() now always multiplied by 63/m_armor. I made the appropriate changes to all places that call shipdamage(). Also, shipdamage() will now tell the player exactly how much their ship was damaged. - a new function mpr(cnum, format, args) will pr() to cnum if they are player and send them a telegram otherwise. - sail, autonav, and nav now all call the same functions. Thus mine damage and interdiction damage are now calculated using exactly the same formulas. This makes heavy use of mpr(). - navigation now has two more lcommands. "i" will list the ships you're navigating, and "f" will change the flagship. - Now you can type commands like this: nav 72 jlsruMluBursh That is, you can mix directions with other navigation commands. - Interdiction of navigating ships now works as follows: 1. Forts interdict. 2. If there are any ships left, land arty interdiction fires. 3. If there are any ships left, ships on interdiction fire. 4. If there are any ships left, interdiction missiles fire one at a time. 5. If there are any ships left, interdicting planes pinbomb. - I'm sure that I've made some changes which have slipped my mind b2r1n contained the following from Ken Stevens: WARNING: Although I have tested most of the new code, I'm sure that it still has a significant number of bugs. This patch contains the following changes: - I went through all of the Empire info pages and updated them to match the current code. I completely rewrote large portions of the following info pages: "move", "bomb", "launch", "navigate", and "Plane-types". - Fixed a bug in the "configure" script which was resulting in a pile of "kw_read" erros in the logfile. - Changed the logfile output to make it much easier to read. Note: this will break current logfile parsers. I'll rewrite any that people need. - It is now possible to specify start-tech/happ/research/edu in econfig (Thanks Julian!). I'm using this in my blitz to start countries at tech 100. - When things are damaged by interdiction, the sector they were moving into will suffer collateral damage. - Surface missiles can now be put on interdiction mission. To distinguish them from anti-ship missiles, the latter have been given "marine" capability. - Planes and missiles can now hold at most one nuclear warhead. - Nuclear warheads on planes and missiles will now detonate when that plane or missile flies an interdiction mission. - I have removed the "n" option from the "bomb" command. If you want to nuke something, just arm the plane with a nuke and bomb "s". This simplification makes the above change consistant with "bomb". - When you launch a satellite, then any country AT_WAR with you will try to intercept it with a-sats. This uses exactly the same code as abm defense - two missiles are fired. Also, if a satellite is positioned over a sector which is not owned by your ally, then they will get a telegram informing of the positioning. - missiles on missions will stop launching once 100 damage has been done (in the case of surface interdiction) or all the ship s have been sunk (in the case of ship interdiction). - deliver now costs the same as distribute (4x cheaper). - there is now only one function called to determine whether a plane/missile hits its target and how much damage is done (this includes abms and asats). Thus the chance of a plane hitting its target is now the same whether the plane was flying a mission or flown by hand. The only exception to this is pinbombing land units where interdicting planes have a 100% chance of hitting unlike pinbombers flown by hand which have a chance of missing. I plan to fix this later. - many functions were rewritten to use mpr() instead of pr(). mpr() checks to see if the person is interactive, and if they are calls pr(), and otherwise calls wu(). All PR() functions should really be changed to mpr() but I'm too lazy to do it. Also, I'm sure that I missed a few pr()'s and so the server may still occassionally try to pr() to a player not logged on. - I used lint to remove alot of unused variables, declare some functions void, and fix unsigned char comparisons with zero. b2r1o contained the following from Ken Stevens: WARNING: Although I have tested most of the new code, I'm sure that it still has a significant number of bugs. This patch contains the following changes: - Added "Friendly" relations--you can nav/load/unload in friendly harbours. See info Empire2 or info relations. - Changed the order of relations so now you can write code like if (rel < FRIENDLY) ... or ... if (rel >= HOSTILE) - Cap sacking now makes the news. - Fixed a bug in sub interdiction (bug introduced by me in r1n). - Fixed a bug in supply code (introduced by Julian in r1f). - Moved relation-change stuff out of decl.c and into subs/rej.c setrel(). So now, no matter how a country becomes hostile, both parties will get a tele and it will make the news. Also, much of this code was simplified using the new heuristic that bad rel is always < good rel. - Changed spy output. New headers are: sect type own oldown eff civ mil shl gun pet food bars units planes - Changed all relevant info pages. - Completely rewrote info relations. *version 2.0 beta 2 release 3* CC is now configurable -

Julian Onions maketgame script added - used to make a temporary test game use as maketgame -d /tmp/data 5 100 to make a temporary game in /tmp/data with 5 countries and 100 sectors each. - Julian Onions fix to make compile script call bin/pconfig instead of util/pconfig -

Also, "mil" on ships/planes/units has been moved from the maintenance costs for those items to the "Military" section of the budget. - If you can not afford to maintain your ships/planes/units or you choose not to maintain them using the "budget" command, then they will loose ETU/5 % efficiency at the update. - If you are broke at the point of the update when it comes time to build something, then that thing will not be built. - Broke countries are now allowed to use all commands except for: arm assault attack board bomb build convert disarm drop enlist explore fire fly grind harden launch lmine mine paradrop recon satellite scrap shoot sweep torpedo treaty upgrade work - Broke countries are now allowed to use these commands: demobilize lload llookout load lookout lradar lrange lretreat ltend lunload march mission morale mquota navigate order qorder radar range retreat sail sonar sorder spy supply tend transport unload unsail emp2.3.5.g.tar - Fixed a server crashing bug in budget command - increased sea mine hitchance from mines/(mines+50) to mines/(mines+40) - increased sector damage from 50 * dam / (dam + 50) to 100 * dam / (dam + 100). - fixed a bug which was preventing engineers from tearing down 100% sectors - added new argument to sonar output which suppresses map - reduced land mine damage from 10 + random(20) to 6 + random(10) emp2.3.5.h.tar - Fixed server crashing bug in "morale" command. - Engineers no longer "raise" eff from 100 to 92, they "lower" it. - Engineers working are now only charged mobility for work they do - Ships fueling themselves now loose petrol/oil - Now, when a sector is abandoned or revolts, the takeover() function is called to stop production, wipe distribution levels, etc... - Engineers are now charged 1 mobility point per land mine laid - Added number of land mines in the sector to the "strength" output - Fixed lots of typos emp2.3.5.i.tar - Fixed a bug in "bomb" which was preventing light bombers on acc's from being able to take off. - Artillery no longer consume petrol or food when they fire (they only consume shells). - increased land mine damage from 6 + random(10) to 10 + random(10) - if land units are accompanied by engineers, then their chance of hitting a land mine is divided by 3. E.g. if there are 25 mines in the sector, then a land unit has a 33% chance of hitting a land mine. If it is accompanied by an engineer, then that chance drops to 11%. - If an engineer sweeps a land mine that it cannot carry, it drops it as a shell into the sector. - Engineers now sweep a number of times equal to 2 times the number of shells they can carry. - The chance of an engineer finding a land mine in a sector is now 50% time the "att" value of the unit: # of sweeps chance of finding a mine old system 5 66% eng1 130 6 60% eng2 165 8 75% meng 260 8 90% - The "visibility" of a sub to an ASW plane has been increased from vis to 10 + vis * 5. This should dramatically improve the chances of ASW planes locating and hitting subs. emp2.3.5.j.tar - changed visibility of subs from 10 + vis * 5 to vis * 4 in the asw hitchance calculation. - when subs on interdiction miss, both parties are now informed (in the old system, neither party was informed) - you are no longer allowed to hit subs with missiles (oops!) emp2.3.6a.tar - Forts will now only automatically interdict ships that the country would be able to see using the "coastwatch" command. Ships out of visual range will not be interdicted by forts. Note that ship/ship, unit/ship, plane/ship interdiction was not changed, and also the "fire" command was not changed. _only_ fort/ship interdiction was changed. - If a NEUTRAL (or worse) ship sails within your coastwatch range, then you will receive a telegram like this: TheBorg lc2 light cruiser 2 (#666) sighted at -9,-1 This telegram is sent before any interdiction is done. - When an ASW plane flies an interdiction mission to hit subs, it will now also report on any subs it happens to see along the way (in the same way it would if it were flown using the "sonar" command). emp2.3.6b.tar - now when you march or navi, any new sector designations automatically appear on your nav map and get added to your bmap (you no longer need to do a "look" to find out their designation. Note that subs will only see sea, harbors, and bridges and will have to "look" (and risk detection) to see anything more. - you can now filter your satellite output to list, for example, only banks owned by country #7 which are over 60% efficient. The selectors available are exactly the same as those used by the "census", "ship", and "land" commands. See "info satellite" for more details. - added two new toggle flags (default on): - if "toggle coastwatch" is on, then you will receive a telegram every time a neutral ship moves within your coastwatch range. - if "toggle sonar" is on, then you will receive a telegram every time one of your sonar cabale ships detects a sonar ping. - now a 20% engineer only does 20% of the "work" that a 100% eng does. - fixed a bug which was counting ghost units in "spy" output. - fixed a bug which was including sats as planes in "spy" output. - fixed a bug which was giving rebels ownershiip of sats over the sector emp2.3.6c.tar I have made asw interdiction more extensive and subs more sneaky. Here is the new system: - ASW planes will now fly out to track any non-FRIENDLY (including NEUTRAL) sub movement. - However there is a chance that the plane won't even leave the ground and notice any sub movement at all. The chance of detection is identchance = (1 - (1 - hitchance)^2). - ASW planes will no longer detect subs they fly over while flying an interdiction mission. - Once the planes have arrived at the sector where the sub movement was detected, then identchance is checked again. If success, then the plane is able to identify the owner of the sub. If the owner is neutral, then the player gets the message: np1 naval plane 1 #2 tracks TheBorg subs at 2,-6 If the plane is unable to identify the owner of the sub, then the player gets the message: np1 naval plane 1 #2 detects sub movement in -3,-3 If the ship was identified as HOSTILE or AT_WAR, then the plane will drop depth charges. - If depth-charges miss, then the ship owner will get the message: RUMBLE... your sub in 24,0 hears a depth-charge explode nearby - torp and fire will now only tell the victim that a "sub" torped them, or that return fire damaged a "sub" (rather than giving out detailed information about the sub number, type, and owner...) - max sonar range has been reduced to 7 and sonar output no longer prints blank lines. - sonar has been changed in the following way: detection = (source "spy" value) + (target "vis" value) If the detection value is less than 8, then sonar will just print Sonar detects sub #12 If the detection value is above 7, then sonar will report the type of sub. Only if the detection value is above 9 will the owner of the sub be revealed. - For ASW planes flying "sonar" or "recon" missions, a similar change has been made. The plane needs to pass one identchance check to see the type of sub, and needs to pass two identchance checks to see the owner of the sub. - Note in both of the above cases, owner and type of FRIENDLY and ALLIED subs will always be revealed. emp2.3.6d.tar - made scrap and scuttle more flexible - supply units, security units, aa-units and artillery can no longer be put on reserve mission, and they will no longer react to a battle. - asw planes were tracking their own subs (oops!) - interest from banks no longer turns off at 60% efficiency. Now the amount of money you get from your bank is simply scaled by the banks efficiency. emp2.3.6e.tar - fixed MAJOR bugs in budget, scrap, and scuttle (oops!) emp2.3.6f.sh emp2.3.6g.tar - Fixed a bug in "work" which wasn't charging them enough mobility - Changed "capitol" to "capital" in a hundred million places - Updated a number of info pages - Fixed output formatting error in "sorder" command - Applied a patch from Jan van Beethoven (AIX port) emp2.3.6h.tar - fixed a bug which was causing dd's to interdict neutral subs. - wrote "info Hitchance" which outlines in detail the chance of anything hitting anything else. This page compliments "info Damage" which gives all the damage formulas. - the defense strength of mountains was reduced to 16 to 8 (the defense strength of a fort). There was a problem of land units in mountains being invulnerable to everything but nukes. emp2.3.7a.tar - missile interception (both abm and a-sat) has been changed so that interceptors are chosen from the owner of the target sector first (so that your ally's abm1's won't launch instead of your abm3's) - if a tradeship won't give the player any cash if it is scuttled where it is, then the player will be asked for a second confirmation before they are allowed to scuttle it. - applied a patch from Ville Virrankoski which fixes a bug in budget (the cost to repair planes on aircraft carriers was not being included in the budget) - fixed a bug which was preventing bombers from being able to drop nukes. - fixed a bug which let asw planes bomb subs they couldn't see - fixed a bug that was sending a telegram to the deity when planes on an acc flew air defense missions. An obscure but annoying bug. - changed isblank() to blankrow() in lib/commands/sona.c for portability - fixed a server crashing bug in lradar (some coder put a global variable in lib/commands/rada.c BAD BAD BAD) emp2.3.7b.tar - fixed a bug in bomb which put the server into an infinite loop when the player aborted at the "commodity to bomb?" prompt. - when your cap is sacked, you now get a telegram telling you how much money you lost and they gained. - when your cap is sacked, then your cap will be moved to a random adjacent (possibly unowned) sector (the treasurers fleeing the palace). This was mainly done because players were retaking mountain capitals every update (you can't redes a mountain to be an aggie!) - added three new files in the doc directory: "PRIORITY", "WISH_LIST" and "WACKY_IDEAS". emp4/doc/CHANGES3.00100644000225100004300000005457306624404745013553 0ustar johnyjohny-grpEmpire 3.0.0 - Implemented the C_SYNC RFC - New commands: sync toggle sync toggle async - New files: h/edb.h h/toolkit.h lib/commands/sync.c lib/global/edb.c lib/subs/prsync.c info/Commands/sync.t doc/CHANGES3.0 - New struct members (currently not used) - player.comhistory command history (for debugging) last 10 commands - nat.nat_mission_trigger set which relation you want to trigger various missions and autodefenses at. - Added land.lnd_scar -- how experienced the land unit is. - sect.sct_mobil was changed from unsigned char to short (to permit the removal of updates--note I don't plan to remove updates, but someday someone might try and they will need this so that sectors can go to negative mob). - New struct members (currently used): - Added type field to all objects so they can identify themselves - Moved var structs to the top of all class structs for easy location (see struct genchrstr defined in h/genitem.h) - nat.nat_hostaddr, nat.nat_hostname, nat.nat_userid, userid and hostname of last person to connect to that country. If when you login, your userid or hostname is different from the last person to conenct to that country, then you will get a message like: Last connection from: Mon Nov 13 01:48:04 1995 to: Mon Nov 13 01:48:12 1995 by: children@RedDragon.Empire.Net this will improve security and be helpful for co-rulers. Also added were nat.nat_last_login and nat.nat_last_logout. - Nation now has 50 realms. - New global constants: - Extended nsc ("next selection conditionals" e.g. cen * ?mil=5) to support C_SYNC messages and include the objects "map" (bmap), and "nation". These will transmit to the client the equivalent of "dump", "ship", "car", "land", "lcar", "bmap", and "nation" output and more. - Added nsc entries for the following classes: sect, ship, plane, land, nuke, map, item, product, and version. These will transmit to the client the equivalent of the "show" and "version" command output and more. Empire 3.0.1 C_SYNC 0.0.1 - changed the order of the struct members of sect, ship, plane, land unit, nuke to put own and uid out front (note this results in a new version of the C_SYNC protocol) - fixed a bug in "sync object" which was sending erronious data - for now all C_SYNC messages will automatically send uid (or x,y for sects). this should be changed to implement "surfacing noises" and interdiction. - whenever any of your sect, ship, plane, land unit, or nuke changes, you will get a C_SYNC message describing the entire new struct. - Note this occurs everytime the data changes EXCEPT for changes which happen durring an update. For now, I will require clients to call "sync object all" after an update if they want to sync their database after the update. - If you loose a sect, ship, plane, land unit, or nuke, then you will get a very partial C_SYNC message only telling you the id and new owner. - look, spy, coastwatch (async & sync), now all send you partial C_SYNC messages telling you information about your enemy's stuff. - Note: For now, you get precise information about the number of mil in the sector etc... This will be fixed in 3.0.2 Empire 3.0.2 C_SYNC 0.0.2 - there is now only one announcement file which all countries post to and read from. the wire syntax has changed to "wire [y|n|]" to allow you to read announcements from days ago if you want. - at each update, all announcements older than 7 days (deity configureable as #define ANNO_KEEP_DAYS in misc.h) are automatically deleted. - a player's bmap can now be changed (e.g. by planes flying missions) even when they're not logged on. - added a new command "sharebmap ". If is friendly towards you and your bmaps already share enough information in common, then your bmap will be added to their bmap. For more details (there are alot more details) connect to empire.net 7773 1-10 and type "info sharebmap". - now whenever a designation gets added to your bmap, the client will receive a very small C_SYNC MAP_CLASS message - when your country's money, reserves, cap location, name or origin changes, you will get a C_SYNC NAT_OBJECT message with your new nation data. Client writers take note: there is a new field in the nat struct called "xstart,ystart" which is the start location of the origin. So if the client needs to make some transformation of the co-ordinates, it can refer to this variable. - when you type "nation", that will also send a C_SYNC NAT_OBJECT message to the client. - removed a bunch of fields from the C_SYNC nat struct (to cut down bandwidth) (this results in a new version of C_SYNC). - information about enemy commodities, tech, or efficiency are now rounded to the nearest 10. Empire 3.0.3 C_SYNC 0.0.3 - added three new land units: "cavalry 2", "light infantry", and "aau1". Here's the basic scheme. The old cavalry are an average between the somewhat weaker cav1 and somewhat stronger cav2. light infantry are half the size of and slightly fastar than inf1's. "aau1" come at the same tech as Zepplins and let low tech countries try to throw rocks at low tech planes... - reduced the size of "ts1 trade ship 1" to 100 lcm, 50 hcm, $1500 (from 200 lcm, 100 hcm, $2500). Most players were waiting for ts2 so this is a nice way to deal with that. - after each update, all countries receive the message "C_SYNC EDB_UPDATE". (this results in a new version of C_SYNC). - all telegram files have been moved into a subdirectory called "tel". - new subdirectory of the data directory "sync" holds spooled C_SYNC messages. - if the player is not logged on when they receive a C_SYNC message, then it will be spooled to their sync file. If the sync file contains spooled messages older than 3 days (deity configurable as SYNC_KEEP_DAYS in misc.h), then the C_SYNC message will not be spooled. - New command "sync read [yes|no]" reads all spooled C_SYNC messages. If the [yes|no] argument is not specified, the player will be asked: "Can I throw this information away now?". - Removed the "bdes" command. It is no longer necessary (since the server now automatically adds 'X' sectors to your bmap, and it also automatically adds sectors that your planes fly over when they're flying missions). The "bdes" command in conjunction with the new "sharebmap" could lead to abuses, and since it is no longer really necessary, I removed it. Given the choice between sharebmap and bdes, I think most players would choose sharebmap. - The delivery and distribution stuff was removed from the output of "commodity" and each column was widened to 5 characters (to accomodate the new system where sectors are now allowed to hold up to 9999 of stuff) - IP addresses will now only be resolved into hostnames if RESOLVE_IPADDRESS (in misc.h) is defined. - Mountains will now mine gold at 1/5th the rate that gold mines do (thar's gold 'n them thar hills!) Empire 3.0.4 beta C_SYNC 0.0.4 - If the game is a blitz, then the "players" command will list other countries which are logged on. This will cut down on the "is anybody else logged on?" announcements. Note that for players, "last command" and "user@hostname" are not printed (only deities get to see this stuff). - fixed a server crashing bug in "sync class all". - each country now has two bmaps, their 'working' bmap and their 'true' bmap. The true bmap contains only information put there by the server. The working bmap also contains information put there by the bdes and sharebmap commands. The "bmap" command usually displays the working bmap unless the player specifies "bmap true". Also, if the players working bmap somehow becomes corrupted, then they can type "bmap revert" to revert their working bmap back to their true bmap. This change was necessary to prevent abuse of the new "sharebmap" command (which now compares the players true bmaps when determining whether they overlap). - There is a new info page 'info Empire3' which contains game changes of particular interest to players. - Put the bdes command back in. - Added a new question in the "configure" script: "Do you require your server to be unusually small?". If the deity answers "yes" to this question, then many bells and whistles will be turned off to generate a lightweight "bare bones" Empire server. - I have padded each object struct out by a spare char, int, and long. This is to give me room in the coming months in case I need to make a change which needs data in the object structs, and I don't want to invalidate currently running long term games. - Tested the HIDDEN and SLOW_WAR mods (these hadn't been tested for the Empire2+ server yet). Empire 3.0.5 beta Note: the primary focus of this upgrade is to address the f1 SAM-soaking problem. The solution I adapted is a mixture of ideas from various people--mostly not myself. I appologize for forgetting whose ideas these were, and I hope that in consolation for not acknowledging you, you will at least be happy that I implemented your ideas. This was a pretty big job. - In the old system, planes would be charged either 10 mobility (interceptors), 12 mobility (escorts) or 20 mobility (the rest) per flight. This cost was then multiplied by (100/eff) with the restriction that plane mobility could not go below -32. Planes flying missions were charged only 1/4 of this. In the new system, planes are charged a base rate of 5 mobility to prepare for takeoff. On top of this, they are charged a "flight cost" which is either 10 (interceptors and escorts) or 20 (the rest), however this flight cost is scaled down according to the length of the flight--it is multiplied by (flight length) / (max plane range). The flight cost is then scaled by (100/eff) with the restriction that a plane can't go below -32 mobility. Planes flying missions are charged 1/2 of this. - The mobility of a plane will now go down by one point for every two points of damage it took from air-to-air combat, to a limit of -32 mob. This is to simulate the high mobility cost of air-to-air combat, and the fact that air-to-air combat is more effort for low tech planes. - SAM interception is now separate from plane interception; for each attacking plane, if the plane cost at least $1000 to build, then one SAM will be launched at it. After SAMs have been fired, fighter planes will intercept what's left over. - The restriction that high tech nations can not build low tech planes has been removed (the above changes address the f1 SAM-soaking problem). - marine missiles on interdiction now fire at a single ship rather than the whole fleet. They pick the ship which is the most valuable according to (cost to build) * efficiency. Furthermore, marine missiles will only launch at a ship if the ship cost at least $1000 to build or if it can carry land units or planes. - the NEWPAF option has been made standard. - fixed a bug which wasn't giving a +1 radius bonus to units in 60% HQ's. - "toggle sync on" now sends back a "sync version" as per the RFC. - fairland now prints an error to stderr if it can't grow the continents (it used to just print the last partially built map). - when you break sanctuary, your 100% sanctuaries turn into cities and all your other sanctuaries turn into roads (this is helpful for games which use "bigstart"). Empire 3.0.6 C_SYNC 0.0.5 - Fixed a bug in the attack code which was underestimating defense strength (it was only giving the sector defense bonus to land units--not mil). Note--the bug was only in the estimation part, so countries were not being given a chance to abort attacks where the odds were clearly against them. - Mountains can now only hold 1/10th as many civs as normal sectors. - Raised the gold production efficiency of mountains from 20% to 75%. - Changed fairland to put gold in mountains. - flash and wall messages are no longer truncated. Instead the message is split into 60 character pieces which are transmitted one at a time. - If the game is HIDDEN then non-contacted countries no longer show up on your "relations" output. - If the game is HIDDEN and you try to declare relations with a country you haven't contacted yet, then you will now get an error message (before you got nothing at all). - Update production reports are now Production Reports again (they were BULLETINS since Empire2.0.0). This will fix a bug which was preventing players from being "informed" when they get an update telegram. - The new info page "info Mobility" gives the formulas for all mobility costs in the game. - Before you type a telegram, you will now see: Enter telegram for Fodderland undo last line with ~u, print with ~p, abort with ~q, end with ^D or . 1024 left: The new tilde escapes work very nicely. - The prompt for escorts has been changed from "plane(s)? " to "escort(s)? ". - Changed the mobility cost to move into a sector from cost = (mcost - eff) / 5 to: if (mcost < 25) cost = (2 + (3 - mcost) * eff) / 5 else cost = (mcost - 20 * eff) / 5 OLD SYSTEM: eff 0% 100% NEW SYSTEM: eff 0% 100% + 0.2 0.0 + 0.4 0.0 m 0.4 0.2 m 0.4 0.2 ^ 5.0 4.8 ^ 5.0 1.0 Note that this means land units can attack 100% mountains now, so there will be a tradeoff for the defender--either they can have a low efficiency mountain that costs more mobility to attack but gets a lower defense bonus, or they can have a high efficiency mountain that costs less mobility to attack but gets a higher defense bonus. - New conditional query "coastal" which gets set when you take a "census" of the sector. Type "cens * ?coast=1" to get a list of all of your sectors which are adjacent to water (and thus vulnerable to assault). - Added a new C_SYNC field to SCT_OBJECT called "coastal". This results in a new version of the C_SYNC protocol. Empire 3.0.7 - Fixed a server crashing bug in the sneak attack code - Sectors with 0 mobility can no longer enlist mil - In a HIDDEN game, you can now only see relations for countries you haven't met yet - Fixed a bug in the "Last login from" part of the login sequence. - added new global array player_commands which keeps a list of the last 100 commands typed by players. Added a file doc/debugging which explains to deities how they can access this list. - Fixed a bug that would prevent you from being able to assault your own sector if SLOW_WAR was enabled. - In a HIDDEN game, llook will now contact. - Fixed a bug in the SLOW_WAR mods which was charging people WarCost to declare war when their enemy was Sitzkrieg towards them. - Fixed a bug in HIDDEN--sending a telegram or auto-coastwatch sighting ships will now both contact. - Fixed a bug in SNEAK_ATTACK--you are no longer charged for boarding a non-at-war ship. Empire 3.0.8 - Removed an infinite from the autonav code. - Fixed the "client" login command. Empire 3.0.9 - Consolidated budget code for ships, land units, & planes (Ville Virrankoski) Empire 3.0.10 - Fixed a bug in radar (anonymous) - Ported the server to Ultrix (Yannick Tremblay) Empire 3.0.11 - Port to FreeBSD (submitted by Janjaap van Velthooven) - Fixed a server crashing bug in range command - Fixed a bug which gave players free info when they shelled deity bridges (reported by Jim Gillogly) - Small ships can now fuel in cities (reported by Walter Smith) - Fixed compile bug in wu.c (reported by Curtis Larsen) - Documented toggle sync and toggle async (reported by Bernhard Reiter) - Fixed a bug in shoot which was leading to abuses (reported by Nathaniel Thurston) - route now prints % sectors (reported by Nathaniel Thurston) Empire 3.0.12 - mkmf is no longer needed to compile the server (Michael Straub) NOTE: This change depends on "cpp -M" working on your system. - A number of bug fixes to the "budget" command (Ville Virrankoski) Empire 3.0.13 - Fixed a bug in "budget" command - If cpp doesn't exist on the system, then "cc -MM" is used in place of "cpp -M" Empire 3.0.14 - Extensive consolidation of "budget" command with update routines (Ville Virrankoski) - Fixed some of the portability problems arising from the switch to "mkdep" Empire 3.0.14a - Fixed a server crashing bug in the update routines (introduced at 3.0.14) Empire 3.0.15 - Fix of a MAJOR bug in the budget/update routines which was overcharging countries for military reserves (Ville Virrankoski) - Simplification & fix of mkdep/configure (Yannick Tremblay) - Port to Solaris 5.5 (Ron Kuris ). Here are the notes that came with the Solaris port: ---------------- These are the patches to make the new server work on Solaris. Some notes: My environment is that we have cc from Sun, but no license. We have gcc installed as /opt/gnu/bin/gcc. Although it was built with Solaris 5.4, it works fine on 5.5. If you need gcc, use archie to exact search for FSFgcc.gz (I found it on qiclab.scn.rain.com in /pub/solaris). You also need FSFtools.gz for gnumake. These packages install very easily. While running configure, your 'gnumake' is /opt/gnu/bin/make, and the compiler you should use is /opt/gnu/bin/gcc. My build path is something like: PATH=/opt/gnu/bin:/usr/ucb:/usr/bin:/usr/sbin:. Once you apply the patches, everything seems to work. Whoever integrates this into the mainstream: The change to client/GNUmakefile is the only one I think that might need tweaking. It sets the default build flags to Solaris (somehow I don't think you want that). I tried pretty hard not to break anything else. The change in lwp.c I think is just an outright bug, but most versions of the lwp system dependent stuff just happen to get lucky by not saving the registers. This should NOT be relied upon! ---------------- Empire 3.0.16 - Optimization of mkdep (Yannick Tremblay) - Moved solaris from emp3 to emp3/make/Systems (Ron Kuris) - Minor enhancement to "lcargo" code (Ron Kuris) - Fixed a bug which had setting budget priorities on land units result in being charged twice for them (Ville Virrankoski) Empire 3.0.17 - "read" command now sends a C_SYNC nation message. (Curtis Larsen) - Fixed a bug which was deleting the announcement file when there were no announcements (reported by Ed Down). - Fixed "~u" tilde-escape for "telegram" and "announce" commands (it was possible to undo back past the beginning of the buffer and crash the server (reported by Nathaniel Thurston). - mkdep optimization (Yannick Tremblay). - Changed syntax for "cede" command so that you can specify "se" or "sh" on the command line (reported by Tero Paananen). Empire 3.0.18 - fixed a serious bug in configure and mkdep which prevented the server from compiling Empire 3.0.19 Ken Stevens 17 Apr 96 - Fixed a serious bug in the Empire3 server which allowed players to create an infinite number of shells and food out of nothing. I added a new field "simulation" to the player struct and set this field to 1 in all update simulation commands (budg, prod, neweff). Then in the update code, instead of checking the variable update_pending to determine whether the update is "for real", I check the player->simulation variable. Note that when the commands sneweff, pneweff, and lneweff get added to the server, they should also set player->simulation to 1. - subs/takeover.c added a check to make sure the number of che doesn't overflow (Paul Byrne) - update/revolt.c. It fixes two problems. First, after security forces kill che, if there are no che left, the function returns without saving the zero-che value. Worse, it never checks for negative che values, which looks like it could happen. The second one is in che moving. It loops through the neighbors looking for the best place to move. Problem is, if it finds a place to move it doesn't move to that place, but simply to whichever place it last looked. (Paul Byrne) Empire 3.0.20 Ken Stevens 21 May 96 [from 3.1.2] - fixed a serious bug in the "production" command which could cause a server crash (Steve McClure). - fixed a bug in the "starve" command which could suck all the food off of a ship or land unit on the ship (Steve McClure). - fixed a bug in the "deliver" command mis-interpreting the return value of the putvar function (Steve McClure). [from 3.1.3] - Fixed a bug in road mobcost calculation (Steve McClure) - Fixed a bug in the toggle command (reported by Keir Novik) [from 3.1.6] - Fixed a bug in the attacking code where moving mil into a sector was going on. It would probmpt for the max amount of mil to move in by mobility, but when you moved in it never checked, so you could still move all the attacking mil in (Steve McClure) - Fixed a bug in fairland (Ken Stevens - reported by Janjaap van Velthooven) - Fixed a bug in map C_SYNC (Ken Stevens - reported by Markus Armbruster) [from 3.1.7] - fairland.c. Better representation of the map for >30 continents. The markings for continents start wrapping for more than 62 continents, the map won't get any control characters anymore (Janjaap van Velthooven). - C_SYNC. forces a newline whenever data with a different id is appended to a partial line. Caveat: this sacrifices the line structure to correct the line tagging (Markus Armbruster). - Fixed a bug which wasn't printing the last row of `sync object bmap' in god's coordinate system (Markus Armbruster). [from 3.1.16] - port to Ultrix (Markus Armbruster) Empire 3.0.21 Ken Stevens 1 July 96 - fixed a bug in reco & sat which wasn't putting a carriage return after land units. - fixed a bug in starvation command which sent the user a telegram telling them how much each of their land units lost due to starvation. - fixed a bug which would send you a message "RUMBLE...your sub hears a depth-charge explode nearby" when you weren't navigating subs (reported by Keir E. Novik) - increased buffer size in emp_client from 1024 to 4096 for sync class version (reported by Markus Armbruster) - fixed a bug in revolt code which could damage a sector below 20% without checking if it was a bridge (reported by Pat Loney) - fixed a bug in SLOW_WAR which prevented you from re-inforcing your own sector by assaulting (Aaron Dewell). - fixed a bug in sack capping news item (reported by Ed Down) - fixed a server crashing bug in "offer" command (reported by Jon Wright) - fixed a bunch of info files (reported by Keir E. Novik) emp4/doc/CHANGES4.X0100644000225100004300000021121707534434144013607 0ustar johnyjohny-grpChanges to Empire 4.2.11 - Sun Sep 1 09:54:59 MDT 2002 * Added compile option for the Mac OSX architecture. * Fixed bug in cargo where unit array was indexed by shp_maxno instead of lnd_maxno. * Fixed bug in reject where aborting the command crashes the server. * Can't buy land units into enemy headquarters. * Added sabotage command and commando unit. * Spies moving by themselves will not trigger interdiction. * Fixed error in map distance calculation that caused errant interdiction. * Ships going under -127 mobility will be set to -127 mob and not roll over to positive mobility. * Corrected plane cost in info Maintenance. * Changed error message for loans rejected for being too big. * Land units will take casualty damage proportional to their ability to carry mil. * Fixed bug where "route i *" crashes server. * Cannot upgrade planes in orbit. * Fixed bug in declare with deity aborting command at last prompt crashes the server. * Coastwatch notify works with NO_FORT_FIRE option. * Thread that kills idle connection will charge player for minutes the player was logged on. * Removed separate sendeof at end of execute from emp_client that logged players off on certain platforms. * Updated player idle counter during read prompt so players wouldn't be kicked off during long flashes or writing telegrams. * LOSE_CONTACT will work as advertised. * Allied units marching through 0 mobility conquered sectors are charged at least LND_MINMOBCOST. Changes to Empire 4.2.10 - Mon Aug 13 14:34:39 MDT 2001 * Assault can reinforce own sector when SLOW_WAR is enabled. * emp_client no longer converts lines into tags but still verifies executes, pipes, and file redirect match players input. * Added pboard command to capture enemy planes in your territory. * Declaring war when at Sitzkrieg won't return relations to Mobilizing. * Declaring war won't charge money if you're already Mobilizing. * Added multiple territory fields. * "show nuke build" displays the proper avail. * retreating land units will only retreat to sectors owned by the player that owns the unit. * added hard cap of "250 + easy" to limit_level. * education p.e. calculation divides edu constant by etu per update. * Added patch for Linux for the PowerPC. Changes to Empire 4.2.9 - Sun Jan 7 15:49:13 PST 2001 * Fixed data corruption when bogus target gets fired upon. * Increased size of ancillary stacks to prevent stack overflow. * Changed all references to empire.cx. * Ships, planes, and land units lost to lack of maintenance will now be lost. * No longer allowed to sack deity's capital. * Accuracy calculation in land unit support was backwards. * Corrected formula for likelihood of plague in info Plague. * Fixed files to correctly size map and bmap files from econfig file. * No longer allowed to add country 0. It corrupts deity country. Changes to Empire 4.2.8 - Mon Oct 9 17:35:35 MDT 2000 * Fixed range in radar.t and Sector-types.t. Maximum range at infinite tech is 16. * Changed so that player can't drop civilians into occupied sectors. * Fixed bug that crashes update if etus/update is less than 8. * Fixed sometimes not reporting overflights * Fixing flak for units/ships to be in all sectors as they should be * Updated order of firing flak in Flak.t. * Fixed 80% efficient planes on ships must be maintained. * Fixed initial MOB_ACCESS check thread sleep time was set by an uninitialized variable. * Removed "TEMPORARILY DISABLED" message from mission command for escort missions. Escort missions have been re-enabled since 4.0.15. * Using sonar from the navigate command will print the sonar map. * Eliminated annoying error messages when using navigate with conditionals. * Fixed Technology.t to correctly add 1 before taking the logarithm. * Fixed bug that allowed players to steal opponents maps. * Put time limit for bidding on market and trade in econfig file. * Moved hours file information into econfig file. * Added comments on setting update policy in econfig file. * Added logging of cases where write extends data file by more than one id. * Option MARKET is turned off by default. Changes to Empire 4.2.7 - Fri Mar 10 18:41:04 PST 2000 * Added new NF_SACKED flag to indicate when a country has had it's capital sacked. This flag is only cleared when the country actively redesignates it's capital using the "capital" command, and changed capital.t to reflect this (no more re-sacking after an update if the country doesn't reset and repeating until they are out of cash.) * Added land unit to edit command for planes. * Added nuketype to edit command for planes. * Changed so that if the leader of a group of units is a train, the railways are used for bestpath instead of roadways. * Changed mission command to also print reaction radius of reserve missions when set for land units. * Changed Flak.t to reflect guns having to be loaded onto a land unit for flak to fire. * Changed so that visitor countries cannot change their name or password. * Changed so that you cannot upgrade deity planes, ships or units. * Changed so that you know where missions are flown from. * Changed so that the airport owner you fly a mission from is informed. * Changed so that preperations for takeoff are reported to the owner of the sector, ship or unit a plane is taking off from if it is not owned by the owner of the plane. * Changed so that when a sector reverts during a guerrilla revolt, the mobility is not reset. When MOB_ACCESS is not enabled, this used to mean you would always get at least an updates worth of mobility. With MOB_ACCESS, sectors that reverted during the update were useless, since you got no mobility for a long time. This fixes that problem, and makes che more useful as well. * Changed so that air defense missions don't always send up every plane in the area, but instead always send up at most two times the number of incoming planes (for each interdicting country.) This helps to stop 1 plane from stripping the mobility from 25 air defense planes all at once, but doesn't limit it to n+1 as there is for regular interception. * Clarified deity reversion of sectors in Sector-ownership.t * Clarified production efficiency and added pointer to "show sector cap" in Product.t * Clarified nuketype selector for planes in Selector.t * Clarified that fortifying units does not affect mission status in info pages for mission and fortify. * Clarified fuel syntax upon error in fuel command in empmod.c. * Cleaned up comments causing minor complaints in some builds. * Fixed bug in loans where you could collect on proposed loans. * Fixed production command to be more accurate (though it *still* has some rounding errors, it's better.) * Fixed potential memory leak in air defense missions. * Fixed bug where you couldn't pinbomb some commodities if other commodities didn't already exist in the sector. * Fixed bug where you couldn't build 0 crew planes without military in the sector. (This is different from needing at least 1 military to build all planes that need a crew which introduced another related bug earlier.) * Fixed bug where scrapping land unit 0 could cause erroneous transfer messages to be displayed for deity owned planes. * Fixed bug where land units on ships in a sector taken over were blown up or captured. * Fixed bug where planes on ships in a sector taken over were blown up or captured. * Fixed bug in sdump printing origx and origy in deity coordinates. * Fixed bug in satellites showing wrong sectors (sometimes) when using the optional arguments. * Fixed bug in launch showing wrong satellite target (showed asat instead of the target satellite.) * Fixed bug where you could gain information not normally available using the "fire" command to determine sector type information. * Fixed bug in market/trade creating extra money when loans are taken out. * Fixed problem with land units not being reported sunk after being sunk on a ship that was nuked or wastelanded in a sector. * Fixed problem with Spies.t using "llook" instead of "llookout". * Fixed problem in lwp/arch.c including jmp_buf.h instead of setjmp.h on some Linux boxes. * Fixed problem with plague infection being way too high in cities when the BIG_CITY option is enabled. * Fixed bug in edit command getting confused with arguments. * Fixed bug in ask_move_in_off asking you to move in a negative number of troops (hey, it could happen. :) ) * Fixed bug in add command not keeping flags or relations initially correct. * Fixed bug in torpedo command sometimes telling victim about torpedo sightings even when way out of range. * Fixed bug in spy command not reporting planes in adjacent sectors, as well as not formatting them properly when reporting them. * Fixed bug in satellite with noisy transmission causing a potential crash of the server with non-100% efficient satellites. * Fixed potential crashing of the server during satellite display when not calculating distances to ships and units correctly. * Fixed bug where planes in non-allied sectors, ships and units could be used on missions. * Fixed bug where planes on the trading block could be used on missions. * Fixed bug where planes and units that get traded don't have mobility set correctly when using MOB_ACCESS option. * Fixed bug which made security units virtually useless. * Fixed access times and mobility not being set right when building planes, ships, units, bridges and bridge towers when MOB_ACCESS is enabled. * Fixed minor formatting problem with launch of satellites. * Fixed minor formatting problem with planes with greater than 999 tech. * Fixed minor formatting problem with ships with greater than 999 tech. * Fixed problem with "llook" showing up in TOP info file. * Fixed problem with lwp Makefile choking on NT builds with clean target. * General cleanup of potentially ambiguous statements. Changes to Empire 4.2.6 - Fri Jun 4 05:55:20 PDT 1999 * Added "TECH_POP" as an option where technology costs more to make as your population grows past 50K civilians. It is disabled by default. * Changed "produce" command to accurately print what the true p.e. is. * Changed "update" command to display if mobility updating is enabled for MOB_ACCESS option. * Fixed bug where toggling off the coastwatch flag also turned off forts firing on hostile ships coming into range. * Fixed bug where assaulting your own land would violate any treaties you have where assaults are a violation. * Fixed bug where all planes (even those without need for a crew, such as missiles) needed at least 1 military to build. * Fixed bug where when a ship sinks during the update due to lack of maint, land units and planes on it were left stranded. * Fixed bug where when a land unit dies during the update due to lack of maint, land units and planes on it were left stranded on it. * Fixed bug where nukes could be lost due to MOB_ACCESS updating mobility while arming. * Fixed bug in "show sector capabilities" not showing products correctly. * Fixed bug in "show tower build" printing "bridges" instead of "bridge towers". * Fixed bug in sectors that don't revolt not showing up as lost items. * Fixed bug where maps with an X of exactly 200 is not drawing third line. * Fixed bug where MOB_ACCESS was not updating the mobility just before the update. * Fixed bug in the way treaties are examined and sometimes produce wrong results. * Fixed edit to allow creating negative mobility for sectors. * Fixed setsector to allow creating negative mobility for sectors. * Fixed bug where when writing out the value of a sector that had negative mobility and was damaged in combat, mobility was being set back to 0. * Fixed Taxes.t info page to reflect that captured civvies only pay 1/4 taxes. * Fixed Technology.t info page to reflect TECH_POP option. * Fixed navigate.t info page to reflect that only ships in the fleet in the same sector that are fired upon have damage divided up. * Made techlists toggle on by default (so things are shown in order of technological advances.) Changes to Empire 4.2.5 - Mon Mar 1 06:42:24 PST 1999 * Added optimization to increasing mobility to check if an object is already at max mob, just return since it can't be increased. * Added "-ltermcap" for client libs for hp build (it was already in hpux build.) * Added clearing of telegram flags after the update so that the next telegram is flagged as new and not part of the update. * Fixed Update-sequence.t to reflect MOB_ACCESS. * Fixed bug where fortification amount was not being limited to maximum mobility for land units (land_mob_max). * Fixed bug where land unit fortification strength was being calculated by using 127 instead of land_mob_max. * Fixed bug where scrapping land units was creating military. * Fixed description of sect_mob_neg_factor in econfig file. * Increased speed of PT boats. Changes to Empire 4.2.4 - Tue Feb 2 05:47:44 PST 1999 * Added check to make military values match up correctly for land units. * Fixed bug in doconfig not putting ipglob.c in the right place. * Fixed bug where attacking deity sectors will violate a treaty. * Fixed newspaper.t information file. * Fixed potential bug in fixing up timestamp information when restarting a game with MOB_ACCESS turned on. * Fixed bug in explore command not setting mobility to correct value when MOB_ACCESS was enabled. * Fixed bug in enlist setting mobility incorrectly sometimes. * Added doc/backup file for deities which recommends how backups and restores of the data directory should be done. Changes to Empire 4.2.3 - Wed Jan 13 06:02:35 PST 1999 * Added linux-pthreads target and build for using pthreads under Linux. * Added NO_FORT_FIRE option which disables the ability of forts to fire when enabled. * Added more error checking and recovery for corrupt data files. * Changed alphapos target to alpha-pthreads for better clarity. * Changed fairland to allow 0 sector distance to other islands and continents (James Risner) * Changed "frg" and "dam" land unit stats to "rng" and "fir" so they match the way ships are described (since this is how they really work.) * Changed Unit-types.t to now describe "rng" as firing range of a unit, and "fir" as the number of guns that a land unit fires. * Cleaned up misc. build warnings. * Changed artillery damage to be 5 + d6 per gun firing from just d6 per gun firing and updated Damage.t to reflect this change. * Changed artillery firing ranges to be like ships ranges - divided by two, and modified them to make more sense. * Changed artillery units to be "slightly" :) more powerful. * Changed "cavalry" unit to tech 30 and lowered mil content to 20. * Changed "artillery" unit to tech 35. * Changed so that guns are no longer required to build units, and that guns must be loaded onto artillery units for them to fire. Client developers note: the show command has not changed yet to remove the 'guns' column (since guns are no longer required) but will in a future revision (possibly 4.2.4) so "be prepared" for "show land build" to change. :) * Fixed landunitgun to handle all the damage calculations like it should. * Fixed bug sinking planes when the ship they are on sinks. * Fixed bug destroying planes when the land unit they are on is destroyed. * Fixed bug where land units could fire support without enough military. * Fixed bug in abandoning sectors by marching out a land unit where it would not let you sometimes (uninitialized variable problem.) * Fixed gets problem in files.c (James Risner) * Fixed bug in determinig operations range of a ship. * Fixed bug in building planes where you could manufacture military. * Fixed warnings in threading package(s). * Fixed fire.t to reflect new firing changes. * Fixed lstat.t to reflect new firing changes. * Fixed sstat.t to reflect the way things really work. * Fixed Ship-types.t to reflect the way things really work. * Fixed the way shutdowns work to hopefully better protect data files. * Fixed bug in attacking when sector mobility is less than 0 and it would prompt for attacking with a negative amount of military. * Fixed typo in fire.t stating wrong parameters for firing from a sector. * Fixed bug in client when it prompts for country name it was putting an extraneous end of line on the end that needed to be stripped off. * Fixed problems running on Linux running on an Alpha machine. Thanks to Rocky Mountain Internet and Jeremy A. Cunningham for giving us time on a machine to work out the bugs. (Note that the only build that works on Linux/Alpha is the linux-pthreads) Changes to Empire 4.2.2 - Sun Dec 27 12:46:34 PST 1998 * Added some code optimizations into the update code when building paths. * Added some new cacheing for building paths to help speed up updates. * Added so that you can use "name" and "password" with the change command as well as "country" and "representative". * Added flag to power command so that if you are a deity and enter a negative number of countries you want to see, you see the power chart for that many countries without power numbers on the next line. Only useful for deities that want to see the chart un-broken up by that line. * Added new functionality to fortify command. You can now use a negative fortification value to cause the unit to be fortified and leave at least that much mobility on the unit. I.E. "fort * -67" will fortify all units and make sure the mobility of each unit doesn't go below 67. If the mobility is already below that level (or equal) the unit is left unchanged. * Added that the realm command prints "Realm #n is x:x,y:y" after you set a new realm. * Added TREATIES option and enabled it by default. * Added "no depth-charging subs" and "no new land units" treaty clauses. * Added Trannie Carter's basic client fix to use fgets instead of gets. * Changed market and command to only print the lowest priced lot of each given commodity by default. If you specify "all" it shows all lots on the market, and if you specify a specific item, it shows all lots of that item type. * Changed start command to only write out sector if it changed. * Changed stop command to only write out sector if it changed. * Changed how plane names were changed on server startup if the PLANENAMES option was enabled. * Changed move command to use standard askyn function for abandoning sector prompt. * Changed plane overlight sightings to take stealth into account, and if the planes managed to evade all flak and interceptors, they are not marked as "spotted" over enemy sectors. * Changed all units with the supply flag to have their marching speeds based on efficiency since that is their purpose. What this means is that supply units and trains are more effective at 100% than at 10% (just as fighting units are more effective at 100% than at 10%, but their effectiveness is determined by how well they fight, not how well they "run away, run away!" :) ) * Changed so that flash toggle is on by default for POGO at setup time. * Changed so that when a sector is taken, all land units owned by the current owner are treated as planes are during takeovers (i.e. there is a pretty good chance they are blown up, and if not, they change owner to the attacker and are beat up pretty good.) * Fixed treaties to work again. * Fixed bug in taking over land units not using correct pointer (can cause a crash or data corruption.) * Fixed collect command to wipe deliver and distribution information correctly. * Fixed potential bug in bmap not working when destination bmap has blank spaces in it. * Fixed bug in shark command not getting right nation structure. * Fixed bug in server where empty commands (for example, all spaces or tabs) were being reported as bogus commands. They are now just ignored. * Fixed bug in scrap not dropping land units off of scrapped units carrying them. * Fixed bug in news where boarding of land units was reported backwards. * Fixed bug in calculating new people when growing them during an update. * Fixed missing -ltermcap in HP/UX build. * Fixed setsector to limit mobility to 127 not 255 (255 was being caught later and being reset to 0 anyway) * Fixed Sector-types.t to show a '\' instead of a '/' for wasteland, since that is what it really is. * Fixed retreat.t documentation to reflect the "retreat upon failed boarding" flag. * Fixed bug where satellites were not orbiting the world during the update. * Fixed bug in torpedos being too smart. They knew how to jump over land! :) Now the "line_of_sight" routine is used to determine if a torpedo has a straight path to the destination. If it doesn't, the torpedo no longer jumps over land, but instead slams into it. This was an interesting bug because you could torp ships on the other side of a very skinny island as long as they were in range, even if there was no sea route possible. * Fixed bug when pinbombing and you run out of an object to pinbomb (land units for example) but you still have to pick something to bomb. For ships it worked ok (just aborted that it couldn't find any more ships) and this was fixed for land units and planes. * Fixed server crashing bug when flying a plane and not carrying any cargo. * Fixed bug in move losing commodities when it runs out of room in the destination sector. Goods are now attempted to be returned to the start sector, and apporpriate steps taken if the start sector is no longer available. * Fixed march to prompt you before you abandon a sector you own by marching out the last land unit. * Fixed check functions to only check the relevant portions of the structure and not the timestamp info that doesn't affect how the object functions. * Fixed bug in spy command that always told you if a spy unit was in a non-owned sector. * Fixed bug in displaying of land unit missions not showing correct land unit range. * Fixed bug in wire command where new announcements that you read at the last second don't get wiped out properly. * Fixed bug where announcement file could be corrupted by very long lines. * Fixed bug where bmap was not set when player was told what kind of sector they were attacking (this was an old abusable bug that was removed long ago to fix the abuse, and it's been fixed in a non-abusable way finally.) * Fixed bug where change command would warn you about monetary and BTU costs, but not prompt you to break out if you didn't want to really change your country name. * Fixed bug in sub-launched nukes that are intercepted being reported in the news incorrectly. * Fixed bug in load where you could abandon a sector and not know it by loading your last civilians or military onto a ship. * Fixed potential memory leak in autonav code. * Fixed potential bug where you could possibly determine if a sector is owned or not using one way plane missions. * Fixed Damage.t info page to properly show damages for planes and land unit shelling. * Fixed deliver.t to include syntax for command. * Fixed country.t to include syntax for command. * Fixed bug where ships on orders were not adding radar information to the bmap during an update. * Fixed bug where ships on sail were not adding radar information to the bmap during an update. * Fixed bestownedpath code to use the bmap properly. Note this is a very important bug fix. When navigating a ship, players are no longer given free information that they would not normally know. For example, if you try sailing your ship off into uncharted areas of your bmap, the bestpath code will only use as much information as you have on-hand (i.e. your bmap) to plan out your path for you. If you have no information on an area, it just keeps forging on, until bumping into something. Of course, after the initial exploration through an area, the bmap will be set and used for all future sailings through that area. Harbors and bridges are still checked for construction worthiness if you know where they are (i.e. they are on your bmap.) (Overall, what happened before was that the bestpath code would route your ship around islands that you didn't even know were there, and you could use various commands to see how that ship was going to sail during the update and thus you gained information that you wouldn't normally know.) * Merged bestpath and bestownedpath and wrote new wrappers, "BestShipPath" and "BestAirPath" to use it properly. It is also good to note that bestownedpath is used to determine paths for ships and for planes, and that best_path (which uses the A* algorithm) is used for all land based paths, and that the two are never interchanged. * Removed "jet recon" plane (it slipped in during the PLANENAMES conversion, and RECON was never used before.) * Removed extraneous "resnoise" and "resbenefit" functions and combined the two for setresource and setsector commands. Changes to Empire 4.2.1 - Tue Nov 3 12:56:20 PST 1998 * Fixed problem with global/plane.c not defining last structure element properly, and thus causing crashes when accessing certain plane routines. This happened during the move to make the PLANENAMES option run-time configurable. Changes to Empire 4.2.0 - Thu Oct 29 06:27:15 PST 1998 * Bumped rev to 4.2.0 since this is a major release (the server is now run-time configurable for just about everything and is released under the GNU GPL.) * Put in official licensing information. * Re-arranged and commented the econfig (Empire Configuration) file. The auto-generated "data/econfig" file is now pumped out chock full of comments (which may or may not be useful.) Since the server is pretty much fully run-time configurable (MAXNOC is not, but it gets a default of 99 anyway) deities will probably be spending more time in the config file. * Added server support for building under NT, including mods from Doug Hay and Steve McClure to get the server building and running under NT. (This was built using MSVC++ 5.0 on NT 4.0 and command line "nmake nt") * Added Doug Hay's ntthread.c implementation for NT threading. * Added max pop column to "show sector stats" output. * Added lboard command for boarding land units from sectors. Only raw mil can board land units, and only mil and land units aboard the unit being boarded fight back. * Added GODNEWS option. When enabled, the deity giving people stuff is shown in the news. * Added bridge tower sector ('@') * Added BRIDGETOWERS option. When enabled you can build bridge towers from a bridge span. You can then build bridge spans from the tower. If the tower is destroyed ( <20% eff) bridges connected fall unless supported on the other side. You can only build bridge towers in open water not adjacent to land and other towers. Expensive. * Added plains sector ('~') - Max pop is 1/40th regular sectors, and it is deity creatable only (can't redesignate unless you wasteland it with a nuke :) ) * Changed "info all" to no longer use printdir, instead it just uses the "all" info page which contains this information. * Changed so you can now load up to 2 spy units onto non-land unit carrying submarines if the LANDSPIES option is enabled. Useful for sneaking up to shore and spying on your neighbors. * Changed so spies unloaded from ships are not given as gifts, they are just unloaded quietly. * Changed build command to handle building towers ("build t") * Changed show command to show tower stats ("show t b") * Changed reject so you can now reject things from any country except deity countries (this now includes sanctuary countries and visitor countries you don't want to deal with) * Changed ndump to dump nuclear stockpile ID as well. * Changed flash so that if someone allied to you is either not logged on or not accepting flashes, you are notified. This is info you could gain otherwise since you can see other countries that are allied to you via players. * Fixed bug in news command when HIDDEN mods are enabled. * Fixed distribute command to only write out to the database if we actually changed the sector (i.e. if we really moved the dist center, we write. Otherwise, it makes no point.) * Fixed threshold command to only write out to the database if we actually changed the sector (i.e. if we really changed the threshold, we write. Otherwise, it makes no point.) * Fixed - population growth and truncation in "Update-sequence.t" info file is now clearer * Fixed the way fortify takes mobility away from a land unit if engineers are present. * Fixed bug in buying commodities at the last minute not resetting the time correctly in all situations. * Fixed bug in building nukes where it would always ask if you tried building more than one at a time. * Fixed bug where if you put (either by building or by transporting) more than 127 of one type of nuke in a sector, they all got lost. A negative wrapover sort of thing. * Fixed ndump to print # of stockpiles dumped. * Fixed ndump.t to reflect changes * Fixed bug in build command that didn't account for EOL characters. * Fixed bug where you could use planes to drop conquered populace * Fixed bug in distribute command in how it checked for current distribution sector. * Fixed pr_flash and pr_inform to no longer send messages if the player is still in the process of logging in (i.e. not in the PLAYING state) * Fixed report command output for deities. * Fixed bug in nuclear damage either taking out submarines when it shouldn't, or not taking them out when it should. * Fixed bug in loading units that are carrying units onto other units (note that it doesn't happen since only HEAVY units can carry other units and that check works, but that might change some day, and we don't want units carrying units to be carried by other units, etc. :) ) * Fixed info pages to reflect new sector types. * Fixed info pages to reflect new spy unit capabilities. * Fixed show commands to only show trade ships if the TRADESHIPS option is enabled. * Fixed build command to only allow building of trade ships if the TRADESHIPS options is enabled. * Fixed up some definitions located in many places used for checking sectors for navigation rights. * Fixed power.t to correctly describe NEW_POWER formula. * Made HIDDEN option run time configurable. * Made LOSE_CONTACT option run time configurable. * Made ORBIT option run time configurable. * Made SAIL option run time configurable. * Made MOB_ACCESS option run time configurable. * Made FALLOUT option run time configurable. * Made SLOW_WAR option run time configurable. * Made SNEAK_ATTACK option run time configurable. * Made WORLD_X and WORLD_Y run time configurable. * Made MARKET option run time configurable. * Made LOANS option run time configurable. * Made BIG_CITY option run time configurable. * Made TRADESHIPS option run time configurable. * Made SHIPNAMES option run time configurable. * Made DEMANDUPDATE option run time configurable. * Made UPDATESCHED option run time configurable. * Made LANDSPIES option run time configurable. * Made NONUKES option run time configurable. * Made PLANENAMES option run time configurable. * Removed SMALL_SERVER stuff (unused baggage) * Removed trading post sector ('v') Changes to Empire 4.0.18 - Thu Sep 24 06:54:27 PDT 1998 * Fixed bug in aircombat where planes in flight could intercept air defense planes and take no damage (i.e. they got to fight twice, once for free.) * Fixed bug in freeing memory after performing missions that could crash the server (it mainly happened after an interdiction mission using planes and escorts, where some escorts came from airports that didn't have bombers going up. Freeing the leftover escorts was crashing the server.) * Fixed bug where you could load non-existant units if you were allied with country #0. * Fixed bug where you could pin-bomb a plane with itself. * Fixed bug where satellites over a bridge may get killed if the bridge is sunk. * Fixed bug where land units on a ship in the same sector as a bridge that is splashed may get sunk. * Fixed bug where planes on a ship in the same sector as a bridge that is splashed may get sunk. * Fixed doconfig with correct empire site text. * Fixed major problem with abms not firing, and sometimes crashing server. * Fixed bug in land units counting up loaded units wrong. * Fixed doconfig makefile to have doconfig.c as a dependency. * Fixed bug in resetting commodities (the comm_uid was not being properly set.) * Fixed bug in repaying loans not working correctly (the l_uid was not being properly set.) * Fixed bug in buying items from the trading block not allowing you to due to a perceived change in item status. * Fixed bug in mfir.c where a bogus input to a target could crash the server. * Fixed bug that after you read telegrams new telegrams may not send an inform message (the old telegram flags were not cleared.) * Fixed bug where fort support distance calculations are calculated twice instead of just once. This bug caused a lower percentage of support fire than designed. * Fixed bomb.t to reflect land unit changes. * Put in some integrity checking for planes returing from bombing runs. * Added ability to edit land unit that a land unit is loaded on in edit command. * Consolidated bridgefall code into "knockdown" function (this code existed in at least 3 places, and was different in all of them.) * Subs returning fire are no longer reported in the news. * Visitor countries can now use the 'motd' command. * When trying to use a visitor country, if it is in use, you are not told by whom, just that it is in use. * Optimized (slightly) support fire from forts not getting supply and shells if not needed (out of range) * Updated Education.t * Modified (increased) chances of hitting mines slightly. * Removed unused variables from shp_check_mines.

(You gotta re-fortify the new guys.) * Fixed bug where planes that were mine capable could not drop mines if they were not cargo capable. * Fixed bug in potentially crashing in update code for nations tech/research. * Fixed bug in execute putting you into execute mode incorrectly. * Fixed bug in board not allowing land units to board from 0 mobility sectors. * Fixed bug where interdicted land units that were missed displayed a "SPLASH! Bombs miss your ships" message. * Fixed bug in minesweeping sectors where, even with mobility or having the sweep ability, ships would get hit by mines for doing nothing. * Fixed bug in count_land_planes always writing out land units unnecessarily. * Fixed bug in count_planes always writing out ships unnecessarily. * Fixed bug in lnd_count_units always writing out land units unnecessarily. * Fixed bug in count_units always writing out ships unnecessarily. * Fixed bug in llook that reported units on ships. * Fixed bug in llook that reported satellites launched over the unit. * Fixed bug in llook that always reported spies (it should be a 10-100% chance) * Fixed bug in anti possibly not saving lost items correctly. * Fixed bug in planes getting extended range when on missions and the op center is not where the plane is located. * Fixed bug in land unit defensive strength not being based on the eff of the unit when calculating odds of a battle. * Fixed bug in board not reporting consistant information. * Fixed bug in the way land unit casualties were being taken. * Fixed bug where land units on ships could return fire. * Fixed bug where land units on other land units could return fire. * Fixed bug where land units on other land units could fire. * Fixed bug in attacks/assaults/boardings spreading plague incorrectly. * Fixed bug in updating plague for ships. * Fixed bug in updating plague for land units. * Fixed bug in updating plague for attacking/defending land units. * Fixed bug where you couldn't pin-bomb land units that were < 20% eff. * Fixed bug which revealed the owner of torping subs when on a mission. Changes to Empire 4.0.16 - Fri Jun 12 08:52:06 EDT 1998 * Added patches sent in by Steve McClure, Sverker Wiberg and Curtis Larsen. They are described with other changes below. * Fixed bugs in the following commands that allowed two cooperating countries to create infinite numbers of any commodity and/or cash at any time (race conditions in the server): build, board, deliver, designate, distribute, explore, fuel, improve, load, ltend, mobquota, move, name, order, reset, sail, sell, set, tend, territory, test, threshold, torpedo, transport, unload * Fixed bug in board command giving out too much information about a non-owned sector when it shouldn't be. * Fixed bug in board command when firing on a sector in defense before checking mobility. * Fixed bug in rangeedit allowing plane(s) to possibly be stored wrong. * Fixed bug in launch allowing plane to possibly be stored wrong after launch. * Fixed bug in lrangeedit allowing land unit(s) to possibly be stored wrong. * Fixed bug in morale allowing land unit(s) to possibly be stored wrong. * Fixed bug in arm/disarm allowing a plane to possibly be stored wrong. * Fixed bug in loan sometimes not writing database correctly. * Fixed bug in collect. * Fixed bug in dropping mines from land units. * Fixed crashing bug in sector_strength routine when oceans take collateral damage. * Fixed bug in transport possibly decrementing too much mobility when moving a nuke. * Fixed some little warning type messages building with gcc -Wall. * Fixed problem compiling lwp threads with glibc6 under Linux. * Changed flash so that players can always flash deities. * Changed players command to always show deities and visitor countries that are logged on, and only show allied countries for normal player countries. * Fixed bug in anti command not stopping sectors when they revolt. * Fixed bug in set_coastal function not counting bridge spans as water based sectors (after all, the land is still a coastal sector, even if next to a bridge span.) * "flash" and "players" is re-enabled for visitor accounts. * Fixed bug in bleeding of technology and research to other players. * Fixed bug in explore not spreading plague correctly. * Fixed bug in move not spreading plague correctly. * Fixed bug in deliver not spreading plague correctly. * Fixed bug in distribute not spreading plague. * Included "postresults" script in the scripts directory which can be used to auto-post daily power chart/announcements to rec.games.empire. * Updated Plague.t * Updated Innards.t * Removed OVCONFIG from build.conf, and patched doconfig to match. * doconfig is only run if needed * emp_client and emp_server are only linked if needed * Added list of disabled options to the version command. * Fixed bug in survey allowing you to see hidden variables. * Re-enabled escort missions due to above bug fix most likely the problem. * Changed one instance of "restrict" to "restricted" in bestpath.c. For some reason, this was causing a problem on one of the Linux builds (??). * Added "show sector capabilities" functionality (this didn't exist before.) * Fixed bug in neweff not reporting stopped sectors. It now (correctly) reports them as not changing eff. Changes to Empire 4.0.15 - Wed May 20 12:35:53 EDT 1998 * Fixed the spelling of Markus' name in CHANGES4.0 files. * Added Markus' patches/fixes.

Changes to Empire 4.0.12 - Tue Feb 24 11:27:31 EST 1998 * Fixed client build on linux (whoops) Changes to Empire 4.0.11 - Tue Feb 10 10:53:10 EST 1998 * AIX build seems to only work with gcc right now (but at least that works) * Vax Ultrix (vaxultrix) build should work now (hopefully) out of the box. * Took out autosupply of airports when bombing or dropping shells. (This was the only commodity this was done for, and it was creating problems since supply is still somewhat broken somewhere) * Included Curtis Larsen's, Markus Armbruster's and Sverker Wiberg's submitted patches, which collectively included cleaning up most of the server prototypes and bogus declarations. Many thanks. * Increased incoming command buffer to 1024 from 512 bytes * Increased the # of parsed arguments from 64 to 100 * Fixed bug where spies were not dying when damaged. * Fixed bug in HIDDEN mods in declare command not printing country # of uncontacted country correctly (or at all as a matter of fact) Changes to Empire 4.0.10 - Mon Aug 18 12:34:58 EDT 1997 * Fixed bug where fleets were being interdicted but the damage was being spread to ships not in the same sectors. * Fixed but in market when buying goods without enough cash. * Planes in orbit over airports are no longer fixed up during updates. * Planes in orbit are no longer damaged when the sectors they are over are damaged. * Planes on ships are no longer damaged when the sectors they are in are damaged, unless the ship is damaged. * Fixed problem with no newline after partisan activity telegram in anti.c * Fixed problem in chan.c printing out change costs incorrectly. * Fixed problem in dispatch.c screwing things up on redirection. * financial should now handle 6 and 7 digit loans. * Planes on ships that are in sectors that revolt are no longer taken over. * Fixed bug in powe.c where the power report was mis-calculating the efficiency of planes. * Fixed doconfig.c to use STDC instead of multi-level #ifdefs. * Fixed bug in parse.c that was screwing up double quotes in conditional arguments. * Military in a sector now only produce up to maxpop, just like civvies and uw's. No more stuffing 6K mil into a mountain to max it out. You can still hold more mil there over the updates, but the extras just won't produce anymore. * Fixed bug in shark that allowed you to shark up loans even if you couldn't cover the debt. * Fixed bug in day of week calculation for server up time in common/keyword.c that is used for gamedays. * Documented what happens to standing military in collect.t when you collect a sector. * Documented mountains only holding and using 1/10th of the normal sector population in Sector-types.t. * Fixed documentation on ship's firing ranges in fire.t to be less ambiguous. * Updated nukes in nuke.t * Added apropos command (thanks to Mike Wise) * Added case-insensitivity to the info command (thanks to Mike Wise).

(This was funny ;-) ) * Fixed bug in "move" where you could keep a sector even after someone else took it from you. * Budget now correctly reports the # of units being built. * Mil on units & ships are now reported as normal military costs, not ship or unit maintainence costs in budget. * Fixed bug in update code where taxes could potentially be initialized incorrectly (affected budgets too.) * Fixed bug in nat.h header so that it uses SCT_MAXDEF instead of a fixed number (that was incorrect.) * Fixed bug with trains - they needed the xlight flag to carry planes. * Revamped and improved flak. * Added "Flak" info page. * Added "Fallout" info page. * Fixed repay/offer/consider to all need a capital to be used. * Fixed bug with air defense missions not running when not AT WAR. They now fly when HOSTILE. * plane/ship/unit short names are all now 4 characters, padded if needed. * pdump/sdump/ldump/ndump now just print the short name for the type. * sdump now has ship name at very end in quotes. These were done at the request of some client developers for ease of use. * Fixed extra space in the dump output. * Fixed fallout - not quite so nasty anymore. * Fixed fallout - things on ships/units are damaged now. * Fixed and balanced planes/ships/units/nukes in conjunction with each other. * Fixed bug in doconfig.c calculating wrong s_p_etu sometimes. * Fixed bug where harbors weren't being used to resupply. * Fixed bug where selling units loaded with planes and units wouldn't take the loaded planes or units - they are now dropped. * Fixed bug in arm/disarm where you could arm/disarm planes on the trading block. * Deities can now remove things from the trading block/market. * Fixed bug in "work" not charging engineers enough mob. * Fixed bug in "work" not adding teardown and buildup avail costs together. * Subs no longer need mobility to return fire when fired upon. * Fixed "reset". * Fixed bug in "trade" allowing 2 players to pay for the same item, but only the last player gets it. * Fixed bug where you couldn't launch missiles from allied ships or sectors. * Fixed bombing so that pin-bombing can cause collateral damage too. * Fixed sector damage to damage planes there too. * Fixed flag in lload so that it doesn't always print if not needed. * Fixed "sell.t" info page. * Fixed bug in "buy" where not entering the price correctly could cause a crash. * Fixed "sell" so that at least 1 mobility is required to sell goods. Keeps the midnight "raid and sell" abuse down. :) * Fixed "show plane cap" to move the last column over 1 more where it should be. * Fixed timestamps to be updated for units/planes on ships/units that move, since those units/planes move too. Changes to Empire 4.0.8 - Wed Feb 26 23:00:51 EST 1997 * Fixed bug in nstr_exec that was wiping out the previous conditional. This was major because it affected timestamp values which are more than 65535. * Fixed bug in sdump.c for typo in reporting the trade ships origin. Changes to Empire 4.0.7 - Mon Feb 24 22:48:54 EST 1997 * Fixed bug in aircombat.c when calculating the air combat odds. Negative numbers were screwing things up good... * Fort sector's coordinates are no longer printed when auto-firing at ships. * Subs can now surface and fire deck guns (again) They can also be hit by return fire when doing so. * Fixed bug in setting of plane attack and defensive values so that negative numbers don't keep going further negative. * Fixed incorrect military control calculation in the sell command. * Trading posts are no longer required to sell goods from. You can sell from harbors and warehouses now too. * Spy now prints out the owner of land units you see when spying. Before this was assumed to be sector owner, which is no longer true. * Loading land units now prints out what was loaded onto each unit, just as loading ships do. * Added fallout, coast, c_del, m_del, c_cut and m_cut to dump output. * Added "GO_RENEW" option. This option means that gold and oil resources are renewable. * Added "lost_items_timeout" config variable, and set the default to 48 hours. This determines how long lost items stay in the lost items database. * Fixed land unit names to be more consistent. * Fixed mission.t info page. * Fixed bug in that if mission_mob_cost was set to 0, even negative mob units should be able to be put on missions. * Removed restriction on things needing to be at least 60% to be put on a mission. Note that while you can put them on missions at < 60% now, when trying to do the mission, it still checks the eff. This is to help in automatic setup (build, put on mission, forget) instead of having to come back repeatedly. * Spies caught in Neutral or Friendly countries cause the Neutral or Friendly country to go Hostile towards the owner of the spy. * Tweaked ammunition numbers for artillery units. * No more automatic declarations of War should be made. You will go hostile, but since going to war doesn't increase your countries defenses, and is purely political, it is left to the player to go that final step. * Fixed bug in trade that wasn't incrementing the time if last second bidding. * Fixed bug in "lmine" that was crashing the server if the land unit was out of mobility. * Fixed buy so that if you specify a product, you can only bid on that type of product. * Added "lost.t" info page. * Added "lost items" database (EF_LOST) * Fixed bug where you could move in allied forces after an attack if they bordered the victim area. * Fixed nstr_comp to deal with values > 16 bits coming in from client for comparisons. * Changed last minute market/trade timers to increment 5 minutes. 2 minutes was too quick. * Fixed decode in lib/common/nstr_subs.c to deal with NSC_TIME better. * Commented out the logging of the market checking in server/marketup.c, lib/commands/buy.c and lib/commands/trad.c It was generating lots of pretty much useless data that made parsing the server.log file more more difficult than it needed to be. * Fixed crashing bug in ldump. * sdump, ldump, ndump, pdump and dump now print out the current timestamp on the "DUMP XXX" line. * Fixed denial of service bug in lib/player/accept.c in player_find_other function. * Fixed bug in shark reporting incorrect buyer of the loan. * Fixed bug in sdump.c (case 0 should have been case 10) * ldump and sdump now always print the fuel column if asked for, even if opt_FUEL is turned off. In the case that it is turned off, the fuel is listed as 0. * Added "timestamp" field, which is updated every time an item is changed. * Fixed up the Clients.t info page. * sdump now prints trade ship building origin. * sdump now always prints name even if SHIPNAMES isn't defined. If it is not defined, then the name is empty. * Added "timestamp" to info/Concepts/Selector.t * Added some more relevant info to info/Server/Empire4.t * Fixed Infrastructure.t info page to reflect the fact that infrastructure is no longer torn down when a sector is re-designated. * Fixed sell.t to more accurately reflect the time-delay market. * Fixed read.t and wire.t to reference accept and reject. * Fixed reject.t not referencing accept command. * Fixed collect.t to more accurately reflect what goes on when collecting sectors. * Fixed financial.t to reflect defaulted loans. * Fixed dump.t, sdump.t, ldump.t, ndump.t, pdump.t to reflect new timestamp info. * Fixed "census.t" (had incorrect reference to "info syntax" instead of "info Syntax". Changes to Empire 4.0.6 - Thu Jan 16 11:33 EST 1997 * Increased damage from depthcharges because on increased damage from torpedos. Sub frange decreased to be more balanced with destroyer frange. * Intelligence reports (spy) on units will now report the estimated number of mil on the unit. * Fixed equation for ship visibility so it will drop as tech increases. * Added new commands sdump, ldump, pdump, and ndump to dump data on ships, land units, planes, and nukes. * If fields are provided, dump will only supply those fields requested. * Decreased speed of subs. * When options NO_LCMS or NO_HCMS are set, those commodities are no longer required for infrastructure improvements. * Units that lose an assault or a boarding attempt from a ship will no longer swim back to the ship they came from. * Units that take extra casualties will no longer lose all their mil at once. * Infrastucture is retained when redesignating a sector. * Dieing spies will no longer crash the server. * Units, planes, and ships must have mobility to perform missions. * Units on ship being scrapped are transferred to harbor. * Food is no longer autoloaded onto units when they are built. * Fixed show plane stat to show correct range. * Infantries now take damage at same rate as casualties. * Fixed bug with hap_fact. Having more happiness now helps with fighting che. * Fixed anti to write back target country so che will continue to fight when they survive. * Fixed llookout to show correct estimate on number of mil on unit. * Added buildable architecture "hp". This type will build the server on a HP/UX machine using the standard compiler instead of gcc. Changes to Empire 4.0.5 - Thu Dec 12 10:28:48 EST 1996 * Fixed bug in update/distribute.c where pathcost was not being called with the MOB_ROAD argument (and thus distribution costs could be GREATLY affected.) - Thanks Ice! Changes to Empire 4.0.4 - Mon Dec 9 11:00:00 EST 1996 * Fixed Solaris port using gcc. * Fixed doconfig.c to create directories with right modes. * Fixed install macros in makefiles to move binaries to the right places. Changes to Empire 4.0.3 - Wed Dec 4 22:46:53 EST 1996 * Added HP/UX port. * Fixed doconfig.c (put exit(0) at the end of main.) * Fixed improve.c (moved the prompt[] string outside the fcn.) Changes to Empire 4.0.2 - Mon Oct 14 12:26:40 EDT 1996 * Put in LND_MINMOBCOST in land.h * Put in change in lnd_mobcost in lndsub.c * Put in new nuke costs in nuke.c * Put in fix so that total work can only be done by the max pop. No more extra civvies tossed in will do it anymore in human.c. * Put in fix for src/util/Makefile - beefed it up. * Put in fix to show where your ship is when it gets shelled in mfir.c. * Changed infrastructure of roads from .040 to .020 (122 instead of 150 in common/move.c) * Fixed Update-sequence.t. * Put in fix for mobcost bonus for 0% highways. * Fixed stop.t * Fixed commodity.t * Spruced up torpedo damage somewhat. :) :) * Fixed "assault bmap bug" in attsub.c * Fixed Produce.t (bars cost) * Changed mountains to get an automatic "2" for defensive bonus in attsub.c * Fixed consider.t * Fixed repay.t * Fixed offer.t * Fixed "offer" and "consider" not being legal commands in player/empmod.c * Fixed Damage.t * Fixed sstat.t * Fixed lstat.c, pstat.c and sstat.c * Fixed cutoff command in cuto.c * Fixed attack value in attack_val in lndsub.c * Fixed lload in commands/load.c * Fixed defense_val in lndsub.c - Made it a minimum of 1, so that units will always fight until dead or retreating. 0 makes them get stuck. * Fixed update/deliver.c - no delivery of non-oldowned civvies (or anything else for that matter.) * Fixed llook in commands/look.c * Fixed che bug in subs/nstr.c * Fixed bug in strv.c by overcompensating by 1 food per sector (minute amounts of people would starve.) * Fixed update/human.c - feed_people rounding problems (I hope.) * Fixed morale problem in update/land.c * Fixed count_bodies in attsub.c * Fixed lnd_mobcost. * Fixed subs/land,plane,ship.c to handle sunken units and planes correctly. * Fixed interest rate in commands/offe.c * Fixed bug in buy.c. * Put in DEFENSE_INFRA soption o you can turn on/off the use of the defensive infrastructure. When off, the defensive infrastructure is the same as the sector efficiency, and you can't improve it. This is OFF by default. * Fixed Empire4.t * Added Wolfpack.t * Land units are now built with a default reaction radius of 0. * Changed name of lt artilleries to "lat" from "lart" so you can now build "lar"s again. * Lowered the speed and firing range of pt boats. * Lowered the initial att strength of cavs from 1.5 to 1.3 (they were TOO powerful.) * Changed the max mob gain defaults of units/planes to 1.0 and ships to 1.5 (This is * ETU_RATE, so it is equal to ETU_RATE for units/planes and 1.5 * ETU_RATE for ships.) * Conquered civvies only pay 1/4 taxes. * Railways don't get torn down when you rebuild sectors anymore (but roads and defenses do (if enabled.) Changes to Empire 4.0.1 - Wed Aug 28 11:35:40 EDT 1996 * Added "extern double tradetax" to check_trade in trad.c * Improved description of data directory in build.conf * Fixed bug in attacking land units that retreat so they now get charged mobility for attacking. * Fixed dump to report road, rail and defense of a sector at the end. * Fixed doconfig bug in not checking the right directory to see if the "data" directory existed or not before trying to create it. * "change" now works for sanctuary countries. * Fixed the description of "sinfrastructure". * Added more info to "Infrastructure". * Units/planes are no longer reduced to 75% when bought from the trading block. * Supply units were slowed down to the speed of infantry units. * Trade-ship payoffs have been lowered to 2.5, 3.5 and 5.0 * Bars interest is up to $250 per 1K again. * Civ taxes were raised back up to a 10:1 mil/civ tax ratio (was 20:1) * Fixed various info pages. * Fixed bug in people not getting truncated when broke (this was thought to be fixed, but wasn't. Now it is, dammit!) * Fixed bug with units marching across oceans (scuba gear not included. ;-) ) * Market/trade taxes and trade ship payoff figures were added to version. * "cede" has been removed as a default command. * Makefile rule was fixed for depend build. * Fixed bug in mapdist not taking world edges into account nicely enough. * Added a "scuttle" order for autoscuttling trade ships. Makes using them easier. Cleaned up scuttle code while in there. * Fixed bug with scuttling a ship with units on it not scuttling the units too. Changes to Empire 4.0.0 - Initial release * Initial Wolfpack release - Long live the Wolfpack!!!! * Cleaned up the build environment. Now all that is needed is to edit the build.conf file, answer the questions there and type "make " to build for a specific architecture. Thus, no more reliance on gnumake or special shell scripts. * We are now shipping the pre-built info pages with the server for those who Don't want to build them. You can also still just type "make" and have the info pages build, but it doesn't completely work (i.e. rebuild new Subjects) if you don't have perl5 installed. * Put in the "help" command that does the same thing as "info". * Removed C_SYNC. This is done for 2 reasons. 1) None of us like it or wish to support it. 2) We envision a better scheme for doing similar things will come along. * Put in MOB_ACCESS - This allows real-time updating of mobility. * Put in MARKET - This is the time-based market (yes, still teleports, but it's not as bad as it was.) * Lots of the documenation has been updated, but there is more to do. * Added NO_LCMS, NO_HCMS and NO_OIL options. When any of these options are enabled, you don't need any of that type of material to build things. If NO_HCMS is enabled, you don't need HCMS to build bridges, you need lcms. If both NO_HCMS and NO_LCMS are enabled, then you don't need any materials to build a bridge. * There is no mobility cost for assigning missions. But, there is also no longer any benefit for being on a mission either. * Damage is the same for all commodities (people too.) This means you can deity shell/bomb sectors again. * Units are now dependant on tech. What this means is that their statistics now increase with tech. In addition, there is only 1 type of each basic unit now (i.e. just "cavalry" instead of "cavalry 1", "cavalry 2", etc.) This reflects the idea that as you learn more, you learn how to not only build better units, but you learn to build units better. :) This also opens the door for a "lupgrade" command along the same lines as the "upgrade" command for ships. * Units now have a minimum mob cost for attacking a sector. Marching mob costs have not changed. * Starting units have been removed. This means that at the beginning, people may live a little longer since their neighbor can't come visiting quite as quick. * Shells are no longer required to build units. * Mil are no longer required to build units. * Mil are no longer an intrinsic part of a unit. They are now a loadable commodity. The way a unit's defense/att bonuses work now are attack = (att * mil * eff) defense = (def * mil * eff) In addition, when a unit takes damage, both the eff and the mil go down. You can quickly toss in new hacks, but you need to wait to repair the unit at the update. Thus, you can now look at unit's efficiency as their training. * You need at least 1 mil on a unit to march it (spies are the exception.) * Units always react if in range and they have the mobility, no matter what their efficency. * Units may now march anywhere - in your own sectors, deity owned sectors or allied sectors, with 1 exception, spies. Also, your units can get trapped if your ally declares non-alliance with you while your units are still in his country.) * Units always march at their speed, efficiency doesn't matter. * LANDSPIES was added - This creates land unit based spies. Spies may march anywhere, with a chance of getting caught (except in allied territory.) See "info Spies" for more info on them. * Planes may now be based out of allied airports. Landing planes on ships/sectors you do not own no longer changes thier owner. You can only land on owned/allied sectors/ships, and you may only fly/bomb/para/recon/drop from owned/allied sectors. So, if a country you are allied with goes hostile at you, your planes are now stuck there. Note that if you are using an allied airport, their commodities get sucked up, not yours (obviously.) * Planes are now tech-based. Their statistics increase as their tech increases. Deleted extraneous planes. * There is a new toggle, "techlists", which allows you to see what you can build/stats/capabilities sorted by tech instead of groupings. * Ships are now tech-based. Their statistics increase as their tech increases. Deleted extraneous ships. * Che can now be lessened by making happiness. If you have more happiness than your conquered populace, they don't fight as hard or recruit as much. If you have less than them, they fight harder and recruit more. It's not much though - it ranges from 2.0 in your favor to only 0.8 against you (whereas it was always 1.0 before.) So, it definitely favors the attackers to make lots of happy now. * Bridgeheads can only be built on coasts. * Players command was fixed so you only see allies, and don't get approx #'s of players anymore. * POSIX threads support has been added. * The attack bmap bug has been fixed. * BTUs regenerate 3 times faster now. * GRAB_THINGS is off by default. * Big nuclear bombs are back, and FALLOUT has been fixed and enabled as a default (you couldn't make wasteland before with FALLOUT, now you can.) * You can now deliver military and civilians. * Added SHIP_DECAY option - off by default (turns off ships decaying out at sea if not enough mil.) * The reverting owner bug has been fixed in territory, thresh, dist and deliver. There are probably more, and when found, will be fixed. * The "sectors don't starve when stopped or broke" bug has been fixed. * The "people never get truncated" bug has been fixed. * Added infrastructure to sectors. What this means is that a sector can now have it's mobility improved by building both roads and railways. It also means that a sectors defense is now based on the defensive infrastructure you build into the sector (no more intrinsic better defenses based on the sector, you determine which sectors are defended heavily, and which aren't.) * The defensive value of a sector no longer relies on the efficiency of the sector. Instead, it relies on the defensive efficiency of the sector. Thus, the "production" and "defensive" aspects of sectors have been separated. * "show sect stats" now shows the maximum defensive value for sectors. * Changed sector structure to take floats for off/def values so we can use a base of 1 instead of 2. * Added "improve" and "sinfrastructure" to support the infrastructure concepts. * Added L_TRAIN units which can only travel along railways. Very fast on efficient railways, slow on non-efficient ones. * Added the ability for units to carry other units. * Fixed census (shortened up "fallout" and "coast" to "fall" and "coa".) * Forts only cost $500 to build and 100 hcms now (since they don't get any better defenses automagically.) * Modified "show sect build" to show the costs for building up the infrastructure of a sector. * Changed "spy" and the satellite recon stuff (which shows sector stuff for spyplanes too) to show the new infrastructure stuff, rounded of course. * Added Drake's info->html scripts, with some modifications, so you can now type "make html" and have your info pages built as html files too. This adds a new directory, "info.html", to the build tree. * Modified upgrade so that planes and land units may now be upgraded. * Added pstat command to list the statistics of your planes. * Added lstat command to list the statistics of your land units. * Added sstat command to list the statistics of your ships. * Added nmap command to show a map of your sectors after their new designations have taken place. emp4/doc/coding0100644000225100004300000001157206624404745013515 0ustar johnyjohny-grp Guidelines for writing Empire code Remarks from Dave Pare: And now, a few editorial remarks on my views on Good Techniques for Modifying Existing Software: My safari through the hot and bug-ridden jungle that Empire has become has given me some new insights on the modification of large software packages. My adventure has prompted me to propose some simple coding guidelines for those dreaming of hacking on the code: 1) Be invisible. When you make a change, think not about marking your place in history, or about showing off how much nicer your two-space tabs are than those old, icky eight-space tabs that the stupid empire hackers of old used, but think instead about the asethetics of the whole. The resulting lines of code should flow smoothly from the beginning of the procedure to the end. Empire is 60,000 lines of code. If you're the general case, you're only changing fifty lines, so be aware of that. 2) Procedurize. If you find yourself in a triple-nested loop, or a five hundred line procedure, perhaps it's because you need to split some of that code off into a procedure. In general, if you've got more than two levels of tabs (or indentations), or more than one or two major loops in a procedure, something may well be amiss. Sasha Mikheev on indentation: The empire indentation style can be achived by using indent -orig -i8 foo.c or in old c-mode emacs (versions before 19.29): ;add this to .emacs (setq c-indent-level 8) (setq c-continued-statement-offset 8) (setq c-argdecl-indent 8) (setq c-brace-offset -8) (setq c-label-offset -8) Further comments by Ken Stevens: 1) Global variables The only variables which should be global are constants. If you write a routine which changes a global variable, then you will corrupt the data when two different players run that routine at the same time. 2) Portability. The following code: char a; #ifdef FOO unsigned char b; #endif FOO Should be rewritten as: s_char a; #ifdef FOO u_char b; #endif /* FOO */ AIX has different conventions for signed chars, and IRIX requires the /* comments */ after #endif. 3) Cut-and-Paste Cut-and-Paste coding is by far the biggest problem that the current Empire suffers from. This is how cut-and-paste coding happens. Joe Shmuck decides that he wants to add a new function to the server. So he goes hunting through the server to find some already existing code which does something similar to what he wants to do. This is good. You should always write new code to imitate old code. What is bad is when Joe Shmuck decides to simply "copy" 200 lines of code from the old function into his new function, and then just change a couple of little things here and there to suit his needs. This method, known as Cut-and-Paste coding is the fastest and easiest way to code. However, it results in a server that is impossible to maintain. What Joe _should_ have done, is "move" the 200 lines of code into a new _third_ function which the first two both call. This is called writing a "general solution" to handle both cases. Most of my work in the Empire2 project consisted in cleaning up after a bonch of Joe Shmucks. I took repeated code and "consolidated" it into general function libraries. 4) Good style. Just to add to Dave's "Be Invisible" motto, I'd like to give a little example to illustrate some basic do's and don'ts for coding style: The following function has bad style: double att_combat_eff(com,own) struct combat *com; natid own;{ double str; double eff=1.0; if(com->type==EF_SECTOR) { eff=com->eff/100.0; if(com->own==own){ str=com->sct_dcp->d_ostr; }else{ str=com->sct_dcp->d_dstr;eff=2.0+(str-2.0)*eff; }else if(com->type==EF_SHIP&&com->own!=own) eff=(1.0+com->shp_mcp->m_armor/100.0); return eff;} Here is the same function written with "good" style: double att_combat_eff(com, own) struct combat *com; natid own; { double eff = 1.0; double str; if (com->type == EF_SECTOR) { eff = com->eff / 100.0; if (com->own == own) str = com->sct_dcp->d_ostr; else str = com->sct_dcp->d_dstr; eff = 2.0 + (str - 2.0) * eff; } else if (com->type == EF_SHIP && com->own != own) eff = (1.0 + com->shp_mcp->m_armor / 100.0); return eff; } These are all the things I fixed when changing the bad to the good: - Function names should always start a new line (so you can search for them) - There should always be a space after a "," - Function arguments should be indented 8 spaces - There should always be a tab after a type declaration - Opening function bracket should be on a line by itself - Indentation should be 8 spaces - There should always be a space on both sides of every operator - There should always be a space after if, for, while, switch - The opening bracket should be on the same line as the if - There should always be a space on either side of a { - There should always be a new line after a ; - The closing function bracket should be on a line by itself emp4/doc/compiling0100644000225100004300000000232407220462766014226 0ustar johnyjohny-grp Compiling the Game Required software: make cc Machine-wise configuration Determine what kind of machine you're on (sun4, sun3, sequent, mipsultrix machine, alpha, etc). Type "make" at the high level, and see if your machine is in the resulting list. If it is not, you will need to edit the high-level Makefile and add support for your architecture in. Send e-mail to: "wolfpack@empire.cx" if you need help doing this. Constructing Binaries First, run "make depend" to build the dependencies. You only need to do this once before the first build. You may run this again if you make significant changes to the code (including new files, etc.) Second, Run "make &" at the top level. Installing Info Pages The INFO pages aren't run as a part of the normal make session. In order to install them, you must cd into the "info" subdirectory, and run "make". This will nroff all the info documents and place them in the "../info.nr" directory, from where players can access them during the game. You will need perl5 installed as your version of perl for this to work. If you add or change any info pages, then be sure to follow the instructions in info/README to generate new Subjects pages. emp4/doc/configuration0100644000225100004300000000175306624404745015121 0ustar johnyjohny-grp Configuring your Empire server Every option within the server has been made Run-time configurable. But, certain things may break if you begin a game and start changing options. One specific thing you cannot change once you have created a world is the WORLD_X and WORLD_Y. If you change these values, you will need to rebuild your world. Most of the other options you should be able to change on the fly. Of course, you probably won't want to be changing options in the middle of a game. But, you should be able to turn them on/off safely. Certain things might get funny (like if you turn on/off HIDDEN in the middle of a game for example) but the server should remain stable. See the "doc/econfig" for a better description of how the Empire config works, and see the "data/econfig" file for a better description of each of the configurable settings in the server. (You may also want to check out the "info.nr/Options" file for more information on individual options.)

If you decide not to dump core, then the most recent player commands should be listed in data/server.log. Each command will be preceeded by the country number of the player which issued it. When the player is prompted, then [prompt] is printed. If you decide to dump core, then the most recent player commands will be in the global array called player_commands which is indexed by player_commands_index. The array will contain strings of the form: "%3d %3d %s", index, player->cnum, command emp4/doc/disk_space0100644000225100004300000000050706624404745014353 0ustar johnyjohny-grp What can I delete? If disk space is a concern, then there are a number of files which you can safely delete without affecting your game.

Some of this is for deities to enable them to configure things, some of it is for coders to see how this stuff works. Julian Onions 15/7/95 -- Also, the Empire config files are now self-documenting (to a point.) Each option/variable now has a comment associated with it to hopefully make life easier on deities wanting to change things. -- Steve McClure, 10/21/1998 -- Deity Notes. ----------- To find out the current configuration, the simplest method is to compile up util/pconfig and the run it. It can be run either with no arguments, in which case it will printout in config format the current compiled in options. Otherwise with a file containing a configuration it will first read in this file, and overright any copmiled in variables and then printout the merged options. So the first method shows you whats compield in, the 2nd how a config file would modify this. Blank lines are ignored, as are lines starting with a # character. Most of the options are straight forward, they take either a string (quote using " to get spaces in it) or a number - integer or floating point depending on the option. For instance privname "The Deity" sets the internal privname variable to that string, and port "7777" sets the empire port to 7777. btu_build_rate 0.0004 sets the internal floating point number for btu building rate, and so on. The only other type of variable currently defined are the options. These may be specified as one or more lines starting "option" and turned off with the keyword "nooption". So, for instance option FUEL ORBIT and option FUEL option ORBIT are equivalent To turn off an option that is compiled in, you can similarly have nooption FUEL nooption ORBIT or nooption FUEL ORBIT As a check, pconfig will printout some of the internal file names as comments at the end just to check they are in the right place. The server can take a -e config file as a command line option so that it will read a specific config file. If not, it will default to looking for a file econfig in the built in data directory, but it won't mind if one is absent. Similarly, util/files and util/fairland et al all take a -e config file to run from a different config. Thus, to start two games on the same host, you might have Game1: files -e econfig1 fairland -e econfig1 emp_sever -e econfig1 Game2 files -e econfig2 fairland -e econfig2 emp_server -e econfig2 econfig1 might have the lines data "/empire/data1" info "/empre/info" port "7777" and econfig2 might have the lines data "/empire/data2" info "/empre/info" port "7778" You only need the lines in that file that you require to override the compiled in definitions, however having all the definitions may help you to understand what is on and off. You could do this with pconfig econfig1 > e1 && mv e1 econfig1 pconfig econfig2 > e2 && mv e2 econfig2 which will fill in all the missing options and values with their defaults. Coders information ------------------ The simplest way to describe this is to step through how a new option would be added. 1. Think of the option name, say, "DUMB". 2. In lib/global/options.c define an integer and set it to 1 or 0 as appropriate. This is usually done as #ifdef DUMB int opt_DUMB = 1; #else int opt_DUMB = 0; #endif 3. At the end of that file, add an entry into the table so it is configurable. This is done with a line like { "DUMB", &opt_DUMB }, Make sure the table is still terminated by two NULL values! 4. In h/optlist.h add an external definition of this variable extern int opt_DUMB; 5. Now the variable is defined, and configurable through the option keyword in the config file. So you can go ahead and make changes elsewhere in the code. This normally looks like if (opt_DUMB) { pr("You're being dumb\n"); } else { pr ("You're being really dumb\n"); } but it may call subroutines, return early from functions or whatever. emp4/doc/files0100644000225100004300000000077506624404745013357 0ustar johnyjohny-grpdoc/ Deity Documentation. man/ Man pages. scripts/ Scripts to help you run a game. bin/ data/ info.nr/ Game binaries, data, and compiled info pages. info/ Nroff source for the Empire info pages. include/ Empire include files (headers, .h files) src/doconfig/ Self-compiling and configuring program for building the server. src/client/ Source code for the Empire client program. src/server/ src/lib/ Source code for the Empire server. src/util/ Programs used to generate Empire data files. emp4/doc/message0100644000225100004300000000103707220463677013673 0ustar johnyjohny-grpHello.

I have changed the path names only since the tree has changed. Otherwise, the docs are correct. -- Wolfpack --- Begin message Hi, I have finished documenting pthreads implementation. Pls look at the results and tell me what can be improved. Implementation: Empire now uses its own thread layer. It makes using another threading library much easier. The interfase is modeled after the LWP library which is what empire server uses by default. The interface is specified in the include/empthread.h file. Implementations should go into src/lib/empthread/xxx.c. Empire assumes that thread can not be preempted while it is running. The _only_ places where context switch between threads can occur are: empth_sleep(), empth_yield(), empth_select(), empth_sem_wait(). That is in sleep, in waiting for I/O on filedescriptor, semaphore or voluntary yielding control or exiting. In empire empth_select is called only on sockets so the context switch can occur only on the network I/O. Also each empire thread can have it is own context which is restored automatically after the context switch. Currently it is used for each thread to have player specic data. (struct player) LWP implementation: Almost nothing has changed there. src/lib/empthread/lwp.c is a very simple wrapper around the LWP library. The only change is that thread inherits its flags if they are not explicitly set. For more details on LWP internals read Dave Pare's description in doc/threads. POSIX threaads: (pthreads) Unlike LWP pthreads are preemtive. The steps must be taken to insure that thread is preempted only as described above. It is done by creating a global mutex mtx_ctxsw. At the any given moment only one thread can be running and have a lock on mtx_ctxsw. Every other thread is waiting for the mtx_ctxsw to become avaiable. It is done by calling pthread_mtx_lock(). When thread enters into empth_sleep(), empth_yield(), empth_exit(), empth_sem_wait() empth_select() it releases the mutex by calling pthread_mtx_unlock() and thus allowing other thread to get a lock. Thread context is implemented by using pthread_getspecific and pthread_setspecific functions. Killing other thread is done by setting victim thread state into EMPTH_KILLED and sending alarm signal to the victim thread. The later has to be done to wake up a thread waiting on I/O in empth_select. Then the victim will examine its state and if it is set to KILLED it will terminate its execution. Unfortunately pthread_kill seems not to be working/exists in some pthread implementations. But fortunately empire always does some I/O before doing empth_terminate(). Semaphores are not available in pthreads thus mutexes and conditional variables are used to implement them. See the code and or OS design book for details. Problems: On linux with libc 2.1.18 mit pthread library does not wake up a thread upon the delivery of a signal. Which means that server can not be stopped short by kill -9 and empth_wakeup() is not working. Fortunately in current server data are always written to player before the call to empth_wakeup so players threads will never wait in select forever. Probably it will be solved when linux libc gets upgraded to latest pthread library. In addition installing pthreads on Linux is difficult. By default linux libc has pthread stubs in but pthread code is disabled. So you have either recompile libc or grab mit pthreads and install them manually. Meanwhile I do not recommend to use pthreads on linux unless you know what you are doing. On solaris 2.5 select does not set errno to EINTR when select is broken by soignal sent by pthread_kill. It doesnt affect anything. On OSF/1 the older version of pthread is used. It has slightly changed function semantics. Also it lacks pthread_kill funcion which means that empth_wakeup() is not working. Calling pthread_exit() from the main thread crashes the program. According to the manual program should not exit until all threads exited. The workaround is to send main into while(1) { sleep(60); } loop; -- Sasha Mikheev There is a saying in Cairhienin, though i have heard it as far away NetVision Israel, Ltd as Tarabon and Saldaea: sasha@netvision.net.il Tel +972-4-8550330 Take what you want and pay for it. http://aldan.netvision.net.il/~sasha emp4/doc/README0100644000225100004300000000207406654424752013207 0ustar johnyjohny-grpThis directory contains the following files: files What's where. backup Recommendations for how to do backups when running a game. troubleshooting Some common problems and solutions. disk_space Stuff you can delete to make more disk space. compiling How to compile the Empire2 server. configuration How to turn options on and off, change game parameters, etc... econfig Details about the syntax of data/econfig. bug-reports What to do if you find a bug. threads Dave Pare explains how lwp threads work. coding Guidelines for coding style CHANGES Revision history for all the changes that were coded in the Empire2 project.

Major changes have occurred. Emp_update, emp_login, emp_tm, and emp_player have been merged. Basically, there isn't anything else besides server. It's big. 60,000-lines of code big. The lib directory now contains nine subdirectories: common gen global as player commands subs update lwp The main directory contains five (code) directories: client lib server util h The server has seven basic threads: main: creates accept, killidle, and update scheduler. sets signals, opens files. accept: opens a socket, binds, listens, and accepts new players. creates a player thread for each new socket. player: negotaties the player's login, and then interprets the player's game commands. killidle: eyeballs the logged-in players every sixty seconds and closes the connections of those who have been idle for longer than 15 minutes. update scheduler: Sleeps until update is due to go off, then instructs all player threads currently running commands to abort them. It waits for a few seconds so that this can occur, and then creates the update thread, and schedules the next update. (This scheduler should produce single, accurate updates instead of double-updates and delayed updates) update: The standard update procedure. It runs at high priority and performs no network i/o, so the game effectively hangs while the update is in progress. select: This thread and its interface provides a mechanism for other threads to deschedule until either a a file descriptor is read/write ready, or a particular amount of time has passed. When the select thread actually runs, the whole process blocks until the select system call returns. However, select runs at the lowest possible priority so other threads get to run to completion before the select gets executed. Overall Notes: Unit and sector files are kept in-core for Your Viewing Pleasure. (It was actually required in order to merge in emp_update) This means the server will use significant memory for the larger games. Per-player bigmap files have been merged into one EF_MAP file, with each player getting one record. This is also kept in-core. Estimated memory cost of a 64-player 256x256 world game with each player having 100 land units, 100 planes, 100 ships, and a bigmap comes to a little over eleven megabytes of space, including the 700k text segment. the "wai()" command doesn't work yet. Implementation Notes: My Opportunity to Spout Empire Technical Jargon Empire is now a miniature operating system, with all that entails. Threads are not simple to use. I know the threads package intimately, and I was confused several times -- probably because the threads interface I provide isn't all that straightforward, even though it seems like it. Hopefully a second iteration by someone who knows what they're doing will be better. I expect this will be much worse for everyone else who hasn't gone through my experience. Bottom line for all you part-time hackers out there: don't mess with the current process model, or you'll get yourself into all kinds of trouble. Thread scheduling and descheduling happens in the io_input and io_output calls. The higher level interfaces in the player thread to these are the getstarg/getstring and pr procedures. If your process ever has to wait for input or output, it will block, allowing other threads to run. Those other threads may well modify data out from under you, so be prepared to have your shared in-memory constructs (ships, planes, sectors, land units, etc) modified out from under you whenever you do i/o. There's a new player global context structure that is shared amongst all the player threads. When a given thread starts or restarts, it sets the global player variable to the appropriate value. Thus, part of the logic of a "context switch" is the setting of player. If you go and add calls to the lightweight process system, you *must* be sure to set the player variable as the io_output and io_input routines do. Otherwise, things will be extremely confused. (I'm not very happy with this global variable, but I didn't have the gumption to do anything more) Most routines that used to return pointers to static space no longer do so. Instead, you're expected to pass in a buffer which will be filled up by the routine. This hit a *lot* of routines, so check the new syntax before using an old and trusted routine blindly. Any files that are loaded into core (like the sector, map, nation, ship, plane, and land unit files) are shared between all the threads. That's good news. If your thread modifies another player's nat_tgms field, he'll see it next time through the command loop, without anyone having to read anything from disk! Furthermore, he'll have no delay in zeroing out that field, so there won't be the annoying double telegram reports which were caused by the delay induced by emp_tm. Unfortunately, modifications to entries to these mapped files must be followed by the appropriate "write record" command (like putship, putnat, etc) or else the changes won't be stored to disk permanently. Update is the exception to this rule, because it writes all records to disk using ef_flush when it's done. This is important, since if and when the players learn how to coredump the server *and* they've managed to build some object w/o their nation record having been updated, they essentially get the item without paying for it. There are two interfaces to the empire file code: the pointer interface exemplified by np = getnatp(cnum), and the copy interface shown by getsect(x, y, §)/putsect(§). Both still work fine. However, you have to be careful when using the pointer interface not to change things prematurely, because any changes to the pointer actually change the data itself -- including putvar, etc. Some commands use the copy interface now, change some variables, and then decide to bail out of the command when something goes wrong. Be careful if you decide to use pointers and then bail out early. Even if *you* don't write the pointer to disk, other subsequent activity probably *will*, resulting in a surprise for the players. Each player thread gets 64k of stack space + more depending on the size of WORLD_X*WORLD_Y. I hope that's enough. If not, we'll have to remove the larger stack variables and move them into static space. Adding new records to core-loaded (EFF_MEM) files is annoying now. Instead of simply writing out a new record, you have to call ef_extend(type, count) to enlarge the file by count records. Additionally, any outstanding pointers you obtained from that file are now invalid. This command results in a "close/open" for the file, requiring the entire contents to be read in from disk again. Luckily, the only instance I saw of this was the "build" command, and my call to ef_extend does it in groups of fifty.

See the EMPIRE WISH LIST for an explanation of the indexing system. _________________________________________________________________ --- TABLE OF CONTENTS --- Attack, Assault and Board.................a Missions..................................m Ships.....................................s Planes....................................p Land Units................................l Commodities and Sectors...................c Information Commands......................i Telegrams, Announcements, News............t Updates...................................u Deity.....................................d Miscellanious and Documentation...........x Error Messages............................e --- ATTACK, ASSAULT AND BOARD --- a4 frontline When a unit is created, it is automatically put on the frontline (except for artillery and supply units). This means that when you attack an adjacent sector, you will be asked if you want to include this unit in the attack. backline When a unit is put on a mission, it is automatically put on the backline. This means that when you attack, you won't be asked about attacking with this unit. Also, supply units and artillery are born on the backline. When attacking with units, allow the user to type Y, rather than typing y for all the units you want to attack with. Y would mean "attack with all units on the frontline". At the attack prompt, you will be asked: Attack with infantry #3 (y/n/Y/N/b)? and the "b" will mean "backline". This would be particularly handy when attacking with a bunch of units and you want to leave some of them behind to hold the beach-head. And you want to stop being prompted for them. --- SHIPS --- s9 swap [s|p|l] Swap the id numbers of units so you can control the order in which they are built. In order to swap the numbers, the units must be in the same sector, and the sector must be either a h/*/! as appropriate. WARNING: this could be seriously abused! s11 nuclear subs consume rads as fuel? need rads to build nuc sub? s17 in fuel command, one petrol should be worth 20 oil. right now it is more efficient to fuel ships and units with oil rather than with petrol. ( in this one, it would probably be better IMHO to get rid of fueling with oil altogether - Ken H.) s20 Make assaulting cost ship mobility. This would help stop the ability to assault with a small amount of mil over and over until reacting units run out of mobility. --- PLANES --- p3 Allow transport planes to paradrop land units. (This would be realistic.) Would use the following analogy: Units on Planes Units on Ships x-light assault para marine cargo light So, "cargo" units could be transported, "x-light" units could paradrop but at a serious disadvantage and would lose all mob, and "para" units could paradrop like marines could assault (with full attack and reduced mob loss). p8 planes should mobility when loaded and unloaded from a ship. p12 Have an aquatic plane type. This would be a medium to small cargo plane, that must be built in an airport but can only take off froma harbor, or sea sector. While on the water, it could tend, however, not be able to nav. It might, or might not be able to lay/sweep mines. And fuel is another issue that would need to be looked into. p14 perhaps the range a plane can fly should be limited by its efficiency. --- LAND UNITS --- l2 trans l to use sector mobility to transport a land unit from one sector to another. l3 Make a new kind of land unit (transport trucks) which can carry land units in a similar way that ships can carry units. This would allow you to transport heavy artillery and unmechanized infantry around faster. (This would be a realistic change). l5 Have very expensive land units called a spies: lcm hcm mil guns shells avail tech $ spy 1 10 0 1 0 0 2 0 $2000 spy 2 10 0 1 0 0 2 0 $5000 spy 3 10 0 1 0 0 2 0 $8000 Spies can march through enemy territory and llook in there. Every update, there will be a chance the spy is caught. Also there is a chance it will be caught every time it moves in enemy territory and every time it does an "lloo". It will be completely unaffected by combat. The chance of detection should be something like: spy 1 10%, spy 2 5%, spy 3 2%. l6 land units should lose mob when loaded/unloaded from a ship. l10 mobile headquarters unit type - capable of repairing land units by using mobility, supplies, and mil. How about just letting engineers work on units also? --- COMMODITIES AND SECTORS --- c9 Limit the amount of commodities (by weight) allowed to be kept on a bridge, and have a stacking limit for units on a bridge. (Bridges can only support so much weight eh?) c10 build tu At a price, build a tunnel through a mountain sector. This would turn a ^ into a + at some great cost. c12 autodemob 11,11 35 y "autodemob" is to "demob" what "autonav" is to "nav". The principle is simple: "autodemob 11,11 35 y" means every update, demob all the mil in 11,11 except for 35. ( note - makes budget more complex - Oliver Ricou ) c14 We need some Empire command which lets you do a lot of moving at once with minimal BTU cost. Here would be one possible syntax: multimove This is just like distribute at the update. It would distribute commodities between and depending on (which applies to the ), and only doing moves provided that the mobility doesn't fall below in any of the sectors involved: empire [124,512]% multimove f * ?civ>20 40 1,1 40 An alternate symtax could be: multimove where existing distribution thresholds are used. --- MISCELLANIOUS AND DOCUMENTATION --- x25 national happiness should be affected by your victories/losses, and if you drown your mil (by scuttle/scrap) or starv your populace. emp4/doc/WISH_LIST0100644000225100004300000001330407220463613013642 0ustar johnyjohny-grp-=O EMPIRE WISH LIST O=- This is the complete Empire Wish List. Each item on the wish list has been given a unique reference number. The reference number does not indicate priority; it is only there so that we may easily refer to various items on the list. The reference numbers are permanent, and any new item added to the wish list in the future will be given a new unique reference number. The blank index number at the bottom of each section refers to the next available index number for that section. Note that the most radical have been moved out of the EMPIRE WISH LIST and onto the EMPIRE WACKY IDEAS LIST which shares the same indexing system as this file. _________________________________________________________________ --- TABLE OF CONTENTS --- Attack, Assault and Board.................a Missions..................................m Ships.....................................s Planes....................................p Land Units................................l Commodities and Sectors...................c Information Commands......................i Telegrams, Announcements, News............t Updates...................................u Deity.....................................d Miscellanious and Documentation...........x Error Messages............................e --- ATTACK, ASSAULT AND BOARD --- a12 aborting an attack should cost you btus or possibly mobility (otherwise you get info for free). a13 --- MISSIONS --- m7 Allow people to specify relation level to trigger different missions (note there is already space for this in the nation struct). m8 --- SHIPS --- s4 For ship/plane/unit specification, allow a/13/b/15/16/c type specification where fleets, wings, and armies may be included along with numbers. (WARNING: This would require massive restructuring.) s13 once ships on sail have arrived at their destination, the "Your fleet lead by ship #x has reached x,y." in production report every time. s22 Another suggestion related to s21. The gain in efficiency of planes on carriers or sufficiently crewed ships on sea should use construction materials etc. This is to make it consistent with land units gaining efficiency in a sector where the necessary materials are present. Otherwise it leads to abuse: Say in the beginning of the game I build a ship but don't want to spend the hcms to build it completely - so I just crew it it will gain efficiency by itself. I think it could easily be implemented by giving every ship some capacity for lcms and hcm's. s24 --- PLANES --- p10 chh [38:382]% scrap p 28,0 ?eff<50 Really scrap all planes in 28,0 [n]? n The prompt is misleading. (Same goes for scuttle). Scuttle and scrap should probably be consolidated. p17 --- LAND UNITS --- l14 perhaps since land units in mountains are so hard to attack, we shuold just not let land units into mountains to begin with. l16 --- COMMODITIES AND SECTORS --- c8 Change bridges (and towers) so that they only crumble when shelled below 15%. Allows attackers an extra chance for a bridge attack. c13 feed If a sector in needs more food, send it food from . c16 - WARNING - may be difficult to code forts should return fire even if shot missed c19 --- INFORMATION COMMANDS --- i5 neweff [s |p |l ] to show the efficiency these things will have after the update. At present you can only get this info by doing some heavy calculations. i10 gstarve lists sectors that need more food if they want to attain maximum civ growth. i12 prod should list the commodities consumed in f h * ! sectors for building stuff. (This would help you calculate your production deltas.) i16 bmap sh to show enemy ships (that you would see with radar or coastwatch). i17 bmap sa to show enemy satellites (that you would see on radar). i18 dump should give you the oldown number, rather than just a *. (Does dump only give you a * if you're not the oldown? I don't know. You can find the oldown using ?oldown= so dump should give it to you). i20 radar [ | ] S shows enemy ships but not your own. i22 cen * ?connect= lists all sectors connected by land to . Handy for setting up territories. i24 Allow | as well as & in selection syntax. e.g. res * ?des=o|des=g (WARNING: cannot use single bar as the or character because "|" is used as a pipe in the standard client and possibly in other clients. Another character should be used instead ( or maybe "||"?) i27 --- TELEGRAMS, ANNOUNCEMENTS, NEWS --- t2 Separate BULLETIN's from Telegrams (so that when we're in the middle of a fight we will know if we were just attacked or we simply have just received a letter from a friend). t9 When you are writing a telegram or an announcement and an update hits, then your telegram or announcement gets lost. ( is it even POSSIBLE to fix this?) t10 --- UPDATES --- u5 Planes should not be built by conquered populace. (The problem here is that building planes uses mil, and you can lose the sector because all your mil that was being used to hold the sector disappeared into the planes so you loose the sector at the update.) ALREADY FIXED? u9 --- DEITY --- d3 Add che (target and number) to deity dump format. d8 --- MISCELLANIOUS AND DOCUMENTATION --- x1 Often BTU's aren't updated immediately, and the prompt is out of sync with the actual amount of BTU's they have. x6 info takeover, avail, loyalty There should be man pages on these. x26 --- ERROR MESSAGES --- e3 _________________________________________________________________ If you have any comments/additions regarding this list, mail them to me at wolfpack@empire.cx with the word "wish" in the subject line.

This file will probably grow over time. (Q) I try to log in as POGO, but the server says, "You're not a deity". Why? (A) If you get a "You're not a deity!" message and logged off, check the "data/server.log" file and look at the end for a "NON-AUTH" entry. There should be a "user@host" message in there that failed to log in. The user and host that your system is using may be different than the one you put in your build.conf file. So, enter this new user and host in the auth file, and you should be able to log into the server as a deity now. Note that if you rebuild the server again, the auth file will be overwritten. emp4/doc/backups0100644000225100004300000000134106654424655013700 0ustar johnyjohny-grpIt is recommended that you take a backup of the "data" directory once in a while in case of system crashes, data corruption, or whatever. It is VERY important to note that you should only take complete snapshots of the data directory and only restore complete snapshots of the data directory. Restoring individual files from backups can cause problems. Some of the known problems with partial restores are: * In games with MOB_ACCESS enabled, mobility will be extremely out of sync if you do not do a complete data directory restore. * Land units, ships and planes may think they are loaded onto ships or land units that do not exist, or have changed owner (been sunk or destroyed and then rebuilt) since the last backup. emp4/include/0040755000225100004300000000000007336035441013174 5ustar johnyjohny-grpemp4/include/bit.h0100644000225100004300000000447307062344105014124 0ustar johnyjohny-grp/* * Empire - A multi-player, client/server Internet based war game. * Copyright (C) 1986-2000, Dave Pare, Jeff Bailey, Thomas Ruschak, * Ken Stevens, Steve McClure * * This program is free software; you can redistribute it and/or modify * it under the terms of the GNU General Public License as published by * the Free Software Foundation; either version 2 of the License, or * (at your option) any later version. * * This program is distributed in the hope that it will be useful, * but WITHOUT ANY WARRANTY; without even the implied warranty of * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

An info page belongs to a subject if # that subject appears as an entry in the .SA ("SEE ALSO") field of the # info page _and_ that entry is not the name of another info page. # # For example, the .SA field of headlines.t contains the entries # "newspaper" and "Communication". Since there's already an info page # called "newspaper.t", but there is no "Communication" info page, then # the headlines info page is considered to be a member of the # Communication subject. # # An info page may belong to more than one subject, and if it belongs # to no subject, then its subject will be set to the name of the subdirectory # it is in (e.g. the Server and Information info pages work this way). # # The output of this script is a bunch of files in the "Subjects" # subdirectory. The file Subjects/TOP.t is the toplevel table of # contents and lists all of the subjects. This is what the player # sees when they type "info". Then for each subject, a # Subjects/Subject.t file is created, listing all of the info pages that # belong to that subject. # # INSTALLATION: # info.pl requires perl5 to run. If you don't have version 5 of perl, then # you'll either have to install it, or you'll have to get someone to create # your Subjects.t files for you. # # HOW TO RUN IT: # Type "info.pl" at the unix prompt. # # BUG REPORTS: # mail your bug-reports and comments to: # Ken Stevens # --- Glossary --- # item.t An info page file # item An info page # Subject An entry in a SEE ALSO entry which is not an item # subdirectory Where the info files are kept # # --- Global variables --- # @dirs Subdirectories of info directory containing item.t files # @Subjects Subjects which already exist (as Subjects/Subject.t) # $dir The current subdirectory we're working in # $filename The name of an item.t file # $filedir{$filename} # The subdirectory item.t is in # F Filehandle for item.t # $desc{$filename} # A one line description of the item (second arg to .NA) # $level{$filename} # The difficulty level of the page.

Note that you need prel5 installed to build the Subject info pages. The default ones are supplied, but if you want to build new ones yourself, you need perl5. To build the info pages, just type "make" at the high level info directory. This will build you the text info pages that the game uses and put them into the info.nr directory. To build the html info page, just type "make html" at the high level info directory. This will build you the html info pages (thanks Drake!) and put them into the info.html directory. Use the "TOP.html" or the "all.html" as the first html pages you reference (TOP.html is better.) --- How to add a new info page --- NOTE: info.pl requires perl5. If you don't have perl5, your Subject.t files will have to be built for you by someone who has perl5. ==EASY INSTALL== To create a new info page, follow these five easy steps: 1. Copy an existing info page and change the relevant stuff. 2. The .SA ("SEE ALSO") line at the bottom must contain at least one Subject (see the Subjects subdirectory). 3. Make sure that the entire .SA line is on one line (i.e. no line-breaks inside the quotes). 4. Type "info.pl". 5. Type "make". ==SECURE INSTALL== If something goes wrong, or if you like doing things carefully, then follow these more elaborate directions: 1. Decide which subdirectory to put your info page in: Commands - Empire Commands Concepts - Game concepts Introduction - General info about playing Empire Server - Info about the server 2. Decide what to call your info page: - If it's an Empire command, give it the same name as the command as listed in lib/player/empmod.c - You may not name your info page any of the following: "Command", "Commands", "Concept", "Concepts", "Introduction", "Server" - Make sure there isn't another info page with the same name in a different subdirectory. - Make sure your info page doesn't have the same name as an existing Subject name (see the "Subjects" subdirectory). 3. Format your info page. Copy the same format as a similar file in the same directory. The first "Title Header" line must be: .TH arg1 arg2 - arg1 should be one of: Command, Concept, Introduction, Server - arg1 should match the directory the info page is in - If arg2 contains more than one word, make sure it's in double quotes - if the info page is for an Empire command, then arg2 must be the command name in ALL UPPERCASE. The second "NAME" line must be: .NA arg1 arg2 - arg1 must be the name of the file - arg2 must be in quotes - arg2 is a one-line description of the info page which info.pl will put on the Subject page that your info page belongs to. The last "SEE ALSO" line should be: .SA "item1, item2, ..., subject1, subject2" - the stuff in quotes is a list of other info pages which are related to this page and info Subjects to which this page belongs. - the stuff in quotes must all be on the same line - You must include at least one subject (see the Subjects subdirectory) in the list (at the end of the list by convention). The lines in between can contain the following formatting characters: Empire command syntax: .SY "command " An Empire command example: .EX "command args" No Formatting: .NF this stuff won't be formatted .FI Begin paragraph: .s1 4. Run "info.pl" Type "info.pl" at the unix prompt. If there are any problems with your info page, info.pl will abort with a clear error message explaining what went wrong. 5. Type "make" This will compile your info pages into ../info.nr ==APPENDIX A - What exactly info.pl does== info.pl reads all of the info pages and creates a table of contents for them organized by subject. An info page belongs to a subject if that subject appears as an entry in the .SA ("SEE ALSO") field of the info page _and_ that entry is not the name of another info page. For example, the .SA field of headlines.t contains the entries "newspaper" and "Communication". Since there's already an info page called "newspaper.t", but there is no "Communication" info page, then the headlines info page is considered to be a member of the Communication subject. The output of this script is a bunch of files in the "Subjects" subdirectory. The file Subjects/TOP.t is the toplevel table of contents and lists all of the subjects. Then for each subject, a Subjects/Subject.t file is created, listing all of the info pages that belong to it. ==APPENDIX B - The checklist.pl script== This little perl script compares the "list" of legal Empire commands in your server with the Empire commands documented in the Commands subdirectory. To run it, login to your game and type: [##:##]% list > list.out Then, move the list.out file to this directory and run checklist.pl. emp4/info/subj2html.pl0100644000225100004300000001062406624404746014762 0ustar johnyjohny-grp#!/usr/local/bin/perl $[ = 1; # set array base to 1 $dome = 0; line: while (<>) { chop; # strip record separator @Fld = split(' ', $_, 9999); procline: if (/^\.TH/) { $str=$Fld[3]; for ($i=4;$i <= $#Fld; $i++) { $str .= " " . $Fld[$i]; } $str = &htmlify($str); printf("%s : %s

.NA anti "anti-terrorist actions"
.LV Basic
.SY "anti "
.s1
 The anti-guerrilla command is used to remove che from any sector.
The command take the following form:
.EX anti 
.s1
Once issued, the strength of the che is
compared to the number of mil in the sector.  The maximum number of mil
allowed to fight is equal to the mobility in the sector.  Che recieve a
combat multiplier which may or may not make
them tougher to kill.  There are only
three outcomes for this command.
.s1
.NF
   1)  The mil kill all the che.  The sector is cleared (for now).
   2)  The che kill the mil.  The sector then returns to the old owner with
       most or all of the che reverting to mil.  The old owner is sent a
       telegram informing him of the event.
   3)  The battle is suspended when the mobility in the sector is used up.
       Each mil or che killed uses one mobility point.
.FI
.s1
Units do not participate in the anti command.  A sector can revert
to the old owner while your units are stuck in it.
.s1
Note that che are finicky.  If you manage to lose a sector fighting them,
they do unpredictable things. 
They may all come out of hiding to join the 
military.  A few may stay in hiding while the majority come out to join
the military.  Who knows what else they may do.

The Empire info pages are organized by subject. It can sometimes be hard to
find the exact page with the information in which you are interested.
To get a list of subjects containing the word you are looking for, type:
.EX apropos 
.s1
without the < and > brackets.

You can then type:
.EX apropos bridge
to get a list of Empire commands and info topics which contain the
word bridge, as well as the line that mentions it.

Apropos is not case sensitive, thus the above example will find
pages with Bridge or bridge (or even bRiDgE).

No nuclear weapons can be delivered unless they are first loaded
aboard delivery vehicles.
However, until they are residing in a plane or missile, they
are considered invulnerable to attack (buried inside of mountains),
and cannot be used by any potential conqueror (they don't know the
fail-safe codes).
.s1
You decide whether the warhead will airburst or groundburst at the
time you arm it.  If you'd like to change airburst/groundburst later
on, just arm the plane/missile again (in this case, the second
argument will be ignored).  You can see whether a nuke will air or

.EX army  
In the syntax  is the alphabetic character to be used as the
army designation.
This character can be chosen from the set of
upper or lower case a-z and tilde (~).
The pseudo-army specification tilde
specifies all units not currently in any army.
.s1
The specification of units, ,
can have one of several syntaxes:

2,3         all units in sector 2,3
-1:3,0:2    all units in the square area bounded by -1,0 & 3,2
.FI
All armies, (with the exception of the `~' army),
are limited to some maximum size
and you will be informed how many units can be added
when this command is run.
.s1
Having units organized into armies can be very helpful in
loading, moving, etc.,
in that fewer commands are required to perform these commands
on groups of units if they can be specified by army number.
.s1
Note that you can remove units from a army by adding them to
the `~' army.  e.g.

The assault command allows your marines to \*Qhit the beaches\*U.
It is also the only way to get ashore other than by unloading at a harbor,
thus it is the first step to gaining land on a new continent.
.s1
Any ship with military can assault a sector containing 0 mil, however
only a landing ship can assault a sector with military in it with
its full complement of troops.
The other ships will only be able to land a fraction of their troops
in any given assault (usually 1/10th).
This represents the use of the Admiral's gig, the Captain's barge, etc.
.s1
Note that some ships will have the
semi-lander flag, which allows them to land 25% of their troops.
.s1
If you have land units with the 'assault' ability 
aboard the ship assaulting, you will be asked if
you wish them to join in the assault as well.
Assaulting land units go to negative mobility when assaulting.
(by an amount equal to the mobility gain per update)
Marine units go to 0 mobility instead.
If assaulting from a ship with the landing ability, a normal unit
pays only mob equal to 1 update's worth of mobility. A marine unit
pays 1/2 that amount. (Example: in a game where land units gain 32
mobility per update, a non-marine unit would pay 32 mobility to assault
from a landing ship. A marine unit would pay only 16 mobility)
.s1
.L NOTE
This mobility loss for units happens whether or not you
own the sector being assaulted. If you wish to land troops
without suffering this penalty, make/capture a harbor!
.s1
If you have ship #28 bearing 10 military at 31,53
it can assault land at any of the adjacent sectors,
(32,52; 33,53; 32,54; 30,54; 29,53; or 30,52).

For example:
.EX assault 32,54 28
.s1
This command asks to assault sector 32,54 from ship #28.
If you assault with 9 troops and assuming the sector has no military,
and since there were 10 troops on the ship to begin with,
90% of the food will be taken along by the assaulting troops,
(and each one that makes it will contribute his or her 10%
to the conquered sector). A minimum of 1 food will be left
on the ship. Land units will not take any food from
the ship, and will only have the food they are carrying.
.s1
You will be asked for any information which was
not included on the command line,
(sector to be assaulted, which ship is doing the assaulting,
number of brave troops to disembark, land units to use).
.s1
The offensive value of assaulting units is cut in half to represent
the difficulty of getting to shore, except for "marine" units whihc
assault at full strength.
.s1
Units may not retreat from an assault, and will take extra casualties
instead if they fail a morale check.
.s1
Other than these factors, assault is the same as normal land combat, with
forts/units/ships/planes firing on both sides to support, etc. Support
arguments are also as in attacking.
.s1
See info \*QAttack\*U for the exact procedure. The sector being assaulted
will have exactly the same reaction to being conquered as if it were attacked
by land.
.s1
You may assault your own sectors. In this case, the assaulting mil
are added to the mil in the sector, and assaulting land units simply
come ashore.
.s1
You may also use assault to sneak spies on land.  To do this, you must
assault with spies only, and they will try and sneak on land. See "info Spies"
for more information.

.NA bdes "Manually change your bmap"
.LV Expert
.SY "bdes  "
A bmap gives you a graphic representation of all or part of your country.
Bdes allows you to change a sector of your bmap.
.s1
Bmap differs from map in that it reflects everything you've learned
about the world. If, for example, you navigate near a sector and find
out that it is as sea, it will show up on your bmap as sea, even if it 
doesn't show up on your map.
.s1
When you get new information, it will overwrite the designation you put in
with bdes, UNLESS you put in an 'x' or an 'X'. These two characters, 'x'
and 'X' are permanent, unless you manually change them with bdes. Once you
change them back, the sector will be updated normally by nav, march, etc.
(The normal use for these is to record minefields, so that you can march
adjacent to the minefield without eliminating the information)
.s1
Unlike normal designation, with bdes, you may use any character.
If you wish to use a space, surround it with double quotes:
bdes # " "
.s1
You can't bdesignate something to a ?
.s1
Conditionals do not work with bdes (i.e. bdes # ?des=c C) unless
you own the sector.
.s1
Note that the bdes command only changes your 'working' bmap and not
your 'true' bmap.  If you make a mistake and bdes a bunch of sectors
where you didn't want them to be, you can always start over by typing
.EX "bmap revert"
which will revert your 'working' bmap back to your 'true' bmap.

.SY "bestpath  "
.SY "bestdistpath  "
.s1
The bestpath & bestdistpath commands show you the best path from any sector

.s1
The path shown by bestpath is the cheapest
owned existing path in terms of mobility.
.s1
Bestdistpath shows the best distribution path that can be found, which
should be the same as the best path..
During the update, sectors distribute to

they can find at that time.
.s1
Note that if you give these commands areas, they will show you more paths.

.NA bmap "Big map of all your worldly knowledge"
.LV Basic
.SY "bmap [ | ] "
.SY "lbmap [ | ] "
.SY "pbmap [ | ] "
A bmap gives you a graphic representation of all or part of your country.
.s1
Bmap differs from map in that it reflects everything you've learned
about the world. If, for example, you navigate near a sector and find
out that it is sea, it will show up on your bmap as sea, even if it 
doesn't show up on your map.
.s1
Note that bmap shows the \*QLAST KNOWN INFORMATION\*U you have about
a sector. It may change, and your bmap will not reflect it. For example,
if you re-designate a sector, it won't show up on your bmap as the
new sector type until you do a map.
.s1
Commands contributing to bmap include (but are not limited to):
map, nav, fly, bomb, recon, para, drop, lookout, coastwatch, radar.
(probably others)
.s1
Your own sectors show up as a designation mnemonic
(see \*QSector-types\*U) while sectors held by other countries
appear as question marks (\*Q?\*U).
Mountains, wilderness areas, and seas appear
as '^', '-' and '.' respectively.
.s1
Note that any sector
marked as 'X' on your bmap will automatically be avoided by
ships when they are trying to calculate the best path between two
points.  Whenever you detect a sea mine in a sector, the server will
automatically put an 'X' on your bmap.
.s1
You can call up a local bmap while navigating or marching by typing 'B'
at the prompt.
.s1
Examples:
.EX bmap -9:18,-8:5
generates a 28 x 14 bmap based on data supplied by the sectors
in the area specified.

and also put the bmap in the file called \*Qmapfil\*U.
.s1
You can also give the number of a ship, and bmap will give you a small
bmap centered on the location of that ship, provided you own it.
If you use lmap, the number of a land unit will give you a map around
that land unit. The pmap command does the same for planes.
.s1
.L "BMAP FLAGS"
.s1
If you specify an 's' flag, bmap will put your ships on the map.
If you specify an 'l' flag, bmap will put your land units on the map.
If you specify an 'p' flag, bmap will put your planes on the map.
A '*' will put all on the map.
.s1
You actually have two bmaps.  One which is created by the server; this
one is called your 'true' bmap.  You can view your true bmap at any
time using the
.SY "bmap  true"
command.  However, usually when you view your bmap, you are looking at
your 'working' bmap.  The only difference between your working bmap
and your true bmap is that your working bmap also contains
designations put on there by you using the 'bdes' command, and by your
friends using the "sharebmap" command.  If somehow your bmap gets
corrupted, you can revert your working bmap back to your true bmap
using the command:
.SY "bmap  revert"

.NA board "Board enemy ship"
.LV Basic
.SY "board [] [ | ]"
The board command enables two ships' crews to engage in hand-to-hand
combat.
To board ship #16 from ship #93 you might type:
.EX board 16
.s1
The program will ask from which ship or sector you wish to board, 
(you may only board from one ship at a time), how many troops to board
with, and which land units (having "assault" capability) to board with.
.s1
In order to be able to board a ship from a ship, your ship must be as fast
or faster than the defending ship.
If you can't catch him, you can't board him!
.s1
The attacking ship will use, based upon its speed, an amount of mobility
to overtake and board the target ship.
If the attacking ship has no mobility, it cannot catch anybody!
Ships' speed depends upon the speed of the ship, the technology
of the owner, and the current efficiency of the ship.
A 50% damaged ship moves one-half the speed it does when undamaged.
.s1
In order to board a ship from a sector, the ship must be in the
sector, and either the sector must have mobility or it must contain
some land units with the "assault" capability.
.s1
Some things to note:
.s1
The defense strength is multiplied by 1 + def/100 where def is the
defense strength of the ship (see show ship stats).
.s1
Other ships belonging to the victim will fire on you when you
try to board, (if you're within range).
.s1
Any land units in the combat will fight as if they were simply mil,
i.e. they won't get any offensive of defensive multiplier, except for
"marine" units which get their full bonus.  Similarly, units
on ships don't have to take morale checks, as they are fighting as mil.
Mil on the victim ship will still die before units take casualties, however.
.s1
Note that you can only board with as many mil and land units that the
ship you are trying to board can hold.
.s1

.NA bomb "Dispose of inconvenient enemy assets with airpower."
.LV Basic
.SY "bomb   mission-type  route|destination"
The \*Qbomb\*U command is used to rain destruction upon helpless
enemy ships, planes, and sectors.
It represents a complete mission for one or more bombers and escorts
taking off from one place and returning to base at the end of the mission.
.s1
 represents a list of planes which can carry bombs.
Only planes which have a bomb bay, belong in a sector which is
stocked with gas and shells, and have sufficient mobility will
be successfully selected for the mission.
.s1
 represent a list of fighter planes which are capable of escorting
the bombers all the way to the target.
To be selected, escorts must have fuel and mobility.
.s1
Mission-type must be one of "pinpoint" or "strategic".
Each mission has different objectives for the planes performing it.
Pinpoint missions allow bombers to attack ships, sector efficiency,
commodities in sectors, and planes on the ground in the target sector.
Strategic missions damage all commodities in the entire target sector,
while not damaging any ships or planes resident (similar to the
ship and sector \*Qfire\*U missions).
If a plane is armed with a nuclear warhead, then it will drop the bomb
rather than using conventional weapons.
Nuclear devices damage everything in the sector; planes, ships, and
commodities.
Only missiles in hardened silos can avoid damage from a nuclear mission.
.s1
 represents an assembly point, where all of the planes in the
mission meet before proceeding on to the target sector.
The assembly point must be owned by you, and must not be more than
four sectors away from any of the planes selected for the mission.
.s1
Route is a normal empire path specification. You may also give a 
destination sector on the command line, or at any time while giving
the route, and empire will use the best path from the current sector
to the desired destination sector.
.s1
When getting a path interactively, empire will show you a small map
(from your bmap) concerning the current area, to help you plot
your course.
.s1
Light bombers (with the tactical capability) are used primarily for pinpoint
bombing.  They perform as well as fighters do for strategic bombing.
Heavy bombers (with the bomber capability), while they can perform pinpoint
bombing, are notoriously inaccurate and in general miss what they are aiming
at.  They are used mainly for strategic bombing.
.s1
During the course of a mission,
your planes may fly over someone else's land.
If you fly over land owned by another country,
and this country is either hostile or in any war state (see info relation)
with you, fighter planes from the enemy country will scramble
and attempt to intercept your force.
If the country is simply neutral,
he will be notified that his radar tracked your planes
as they flew over his country.
If the country is allied, then nothing will occur.
.s1
If you manage to fight though the enemy fighters and arrive
at the target sector, your force must still contend with
any flak guns which your enemy has stationed there.
What's more, any enemy ship in the target sector will also
shoot at each of your bombers before any attacks are performed.
Any enemy land units with the 'flak' ability will also fire at 
all your planes at this time.
.s1
A well-equipped fleet of battleships in a heavily-defended harbor
can be very risky to attack, even though hitting ships in harbor is
like shooting fish in a barrel.
.s1
When bombing ships/planes/units, entering a '~' character will cause a 
particular plane not to bomb. Other planes on the mission will still
be asked for their targets.
.s1
If your plane has anti-submarine
(asw) capabilities, you will be told when you arrive in a sector whether
it has submarines in it. If you then choose to pin-bomb ships, each plane
in turn will attempt to find submarines (this ability varies with the plane's
accuracy rating).  Each plane can only bomb the subs it can find. (It
is assumed
that planes on anti-sub missions split up to cover the area)
.s1
Planes have differing air-to-air combat abilities, differing ranges,
and load-carrying capacities.
Some airplanes don't need runways, but can operate out of any
sector which has fuel in it.
.s1
ASW capable planes may attempt
to fly pin-bombing missions versus submarines. To do this, the plane
gives a target sector, and flies there. If there are any subs in the
sector, a message will be printed saying that. If the plane then 
attempts to bomb ships, it may get the chance to bomb subs in the sector.
.s1
The chance to detect a sub is the same as the chance of hitting it.
.s1
If the plane does not detect a particular sub, it may not bomb it on that
mission. On other missions, it could roll again.
.s1
Trying to pinpoint bomb land units is similar to trying to bomb a sub.
The chance to find the unit to bomb it is based on the unit's 
visibility & the type of the sector it is in. 
.s1
When you pin-bomb a land unit, it will fire flak at the plane bombing it,
unless it is an 'flak' unit (in which case it fired earlier), or 
it has an AA fire rating of 0. 
.s1
In the case of pinbombing, see \*Qinfo Hitchance\*U for the formula
determining whether a plane hits its target.
.s1
Note that a plane must be at least 40% efficient before it can leave
the ground.

Budget takes into account avail in headquarters,
harbors and airports, and will
only show you how much you'll pay for work that will actually get done
in cases where your headquarters/airports/harbors will not have enough avail
to work on all units/planes/ships.

If a cost is in [ brackets ], then that means that you will not pay it
because you will not have enough money.  If a cost is in ( brakets ),
then that means that you will not pay it because you have chosen not

.NA build "Build ships, planes, bridges, land units or nuclear weapons"
.LV Basic
.SY "build [land|ship|plane|nuke|bridge]  [unit-type|ship-type|plane-type|nuke-type|direction] [Number to build] [tech] [sure?]"
The build command is used to specify the types of units to be built
at your headquarters, ships
to be built in your harbors, the planes and missiles at your airfields,
the nuclear devices at your nuclear production facilities,
and the directions in which bridge spans are to be built.
.s1
The ability to produce units, ships, planes, nukes, or bridges, is based on
several factors:
labor force, light production units, heavy production units,
oil units, radioactive material units, available cash,
and technology level.
The quantities or levels required vary with the object being built.
.s1
In order to build anything, the sector involved needs to have
avail. Avail is work available in the sector after the demands
of the update (building efficiency, working on things, etc)
Avail in the sector is show in the output of the \*Qcensus\*U
command in the 'avail' column.
.s1
The "Number to build" option may only be given if the command is being
specified totally on the command line. If you give multiple sectors and
a number to build, it will attempt to build that number at EACH sector
specified.  If you ask to build more than 20 units, it will ask you
"are you sure you want to build so many?".
.s1
If you don't specify TECH then it will build the unit at your current
tech level.
.s1
BUILDING BRIDGES
.s1
If you type
.EX build b 1,3
and 1,3 has enough hcm (heavy construction
materials), the workforce in the sector is large enough (as defined above),
you have enough money, and your technology level is high enough,
then the program will respond:
.NF
Bridge head at 1,3
 + k
o a .
 . .
build span in what direction? n
.FI
.s1
With the EASY_BRIDGES option enabled, bridges may be built from any sector
that is at least 60% efficient.  Otherwise, bridges may only be built
from bridge-head sectors.  The
sector the bridge span is to be built in must be adjacent to
at least 1 non-sea, non-bridge span sector.
.s1
If everything is correct, you get:
.NF

Bridge span built over 2,4
.FI
To find out the required amounts of materials, workforce, and money
use the \*Qshow bridge build\*U command.
.s1
You may now also build bridges all in one line as in:
.EX build b 1,3 n
.s1
A sector that has a bridge built in it is automatically cleared
of mines at the time of building.
.s1
Bridge spans are built at 20%.  If the efficiency drops below 20% (due
to bombing, shelling, etc.) the bridge span falls.
.s1
If a bridge falls, all mines in the sector are likewise cleared.
.s1
BUILDING BRIDGE TOWERS
.s1
If you type
.EX build t 1,3
and 1,3 has enough hcm (heavy construction
materials), the workforce in the sector is large enough (as defined above),
you have enough money, and your technology level is high enough, and the
sector is a bridge span,
then the program will respond:
.NF
Building from 1,3

build tower in what direction? n
.FI
.s1
Bridge towers can only be built if the BRIDGETOWERS option is enabled. 
.s1
In addition, bridge towers can only be built in open water, i.e. not 
adjacent to any land or other bridge towers.  Bridge towers must be
built from bridge spans that are at least 60% efficient.
.s1
If everything is correct, you get:
.NF

Bridge tower built in 2,4
.FI
To find out the required amounts of materials, workforce, and money
use the \*Qshow tower build\*U command.
.s1
You may now also build bridge towers all in one line as in:
.EX build t 1,3 n
.s1
A sector that has a bridge tower built in it is automatically cleared
of mines at the time of building.
.s1
Once a bridge tower is built, you may build other bridge spans from it.
.s1
Note that you cannot navigate through a bridge tower like you can through a
bridge span.
.s1
Bridge towers are built at 20%.  If the efficiency drops below 20% (due
to bombing, shelling, etc.) the bridge tower falls.
.s1
If a bridge tower falls, all mines in the sector are likewise cleared.
In addition, if a bridge tower falls, all bridges around it are
knocked down unless they have another supporting bridgehead (such as
another tower, bridge head or next to land if EASY_BRIDGES is on.)
.s1
NUCLEAR PLANT SECTORS & BUILDING NUKES
.s1
If you type
.EX build 6,2
and 6,2 is a nuclear plant that has enough hcm
(heavy construction materials),
lcm (light construction materials), oil, and radioactive material,
the workforce in the sector is large enough (as defined above),
you have enough money, and your technology level is high enough,
then the program will construct a new nuclear device of the type
requested, and add it to the current stockpile in that sector.
.s1
Note: If the DRNUKE option is enabled, you will need a certain amount
of research to make nukes. At the present time, it is 1/3 the amount of 
tech needed to make the nuke. See the \*Qshow\*U command, which lists 
this if applicable.
.s1
TYPES OF THINGS YOU CAN BUILD (besides bridges)
.s1
Many different types of units/ships/planes/nukes are available.
For a brief table indicating the production costs of the
different things, respond with \*Q?\*U when asked for the type,
or use the \*Qshow\*U command.
Note that if there are two things in the list of items that are
similar, such as "destroyer 1" and "destroyer 2", you will need
to give the full name, or the program will build the first one
that it encounters.
.s1
\*QNote:\*U if you wish to give the ship-type argument on the
command line, it may be necessary to quote the ship-type. For
example: build s 0,0 "lander 2" 80 would build a lander 2. Without
the quotes, it might build a lander 1 instead, since the ship-type
is two words.
.s1
Once built, units/ships/planes grow in efficiency until they reach
100%. This growth is accomplished using the avail left in the sector
at the time of the update, so if you use all the avail building things,
there won't be any left to make them more efficient. The avail there
is divided amongst all things in the sector needing work, so the more
units/ships/planes there, the less each will be worked upon.
Ships/planes/units also require materials be present in the sector to
gain efficiency. In general, for each 1% the ship/plane/unit gains in
efficiency, it will use 1% of the materials listed by \*Qshow\*U.
.s1
HEADQUARTERS SECTORS & BUILDING LAND UNITS
.s1
Land units are built in headquarters sectors. (designation !).
In order to build a land unit, you must have 10% of the items
listed by \*Qshow\*U (typically military, lcms, hcms, guns, shells,
petrol, etc) available at the time of building. The land unit will
appear at 10% efficiency (a unit of less than 10% efficiency is
dead). Then, 
each update, the unit will grow in efficiency, and use up more
of the required goods until it reaches 100%.
Land units can also gain efficiency in fortress sectors, but cannot
be built there.
.s1
The work required to add a point of efficiency to a land unit is 
.s1
.NF
(20 + (lcm_to_build + 2 * hcm_to_build))/100
.FI
.s1
A land unit will can gain efficiency in any other sector type (assuming
the correct goods are available), but at 1/3rd the normal rate.
.s1
HARBORS & BUILDING SHIPS
.s1
Ships are built in harbor sectors. 20% of the materials
listed by \*Qshow\*U must be available at the time of building.
(typically hcms & lcms)
Ships first appear at 20% efficiency and a 19% efficient ship
will not float (i.e., it sinks). Then, each update, the ship will
grow in efficiency, and use up more of the required materials until
it reaches 100%.
.s1
In addition to the avail in the harbor sector, ships are also
worked on by their crews.  So, for fastest efficiency growth,
put full crews on your newly built
ships and leave them in harbor until they reach 100%.
.s1
The work required to add a point of efficiency to a ship is 
.s1
.NF
(20 + (lcm_to_build + 2 * hcm_to_build))/100
.FI
.s1
Ships at sea have only their crews to make repairs.
Crew members each supply the same amount of work,
whether civilian, military, or uncompensated worker.
A small crew on a large ship
may not be able to make any repairs at all.
(Moral: keep your ships fully crewed in anticipation of future damage.)
Repairs at sea do not use any lcms or hcms, but may not push the 
efficiency of a ship over 80%.
.s1
Entropy acts on ships without sufficient crews. In general, if a ship
is at sea, and has less than about 40% of its maximum crew, it
will gradually rust, take on water, and sink.
.s1
.NF
	The amount of efficiency lost depends on the ship size and crew level.

	Figure the following quantities:

	Avail is the work done by the crew: 

		On a military ship: work = etus * mil/2
		On a civilian ship: work = etus * (civ/2 + mil/5)

	Crew is the current # of mil (for a military ship), or civs for a
civilian ship.

	Max crew is the max # of mil/civs (depending on ship type)

	W_p_eff is the amount of work per point of efficiency of the ship:

		w_p_eff = 20 + (lcm + 2 * hcm);

	Lcms & hcms are the cms required to build the ship.

	Then,  subtract (etus * (100-((crew*100)/max_crew)))/7 from the avail.

	If the result is less than 0, divide it by the w_p_eff, and subtract
	that amount from the ship's efficiency.

	avail -= (etus * (100-((amt*100)/abs_max)))/7;
	ship->shp_effic += avail/w_p_eff;
	Example: A frigate (a military ship) can hold 60 mil. It has only 10.
	
	w_p_eff = 20 + (lcm + 2*hcm) = 20 + (30 + 2*30) = 110
	Avail = etus * mil/2 = 60 * (10/2) = 300

	300 - (60 * (100-((10*100)/(60)))/7) ~= -420

	Since the result is negative, divide it by w_p_eff:

	420/110 = 3.8 = 4% loss of efficiency

	Note from this that the frigate would need 24 crew to break even.

AIRPORT SECTORS & BUILDING PLANES
.s1
The choices range from low tech \*Qfighter 1\*U planes
up to and including super-long range \*Qjet hvy bomber\*Us
and \*Qicbm\*Us.
For a brief table indicating the production costs of the
different plane types respond with \*Q?\*U, or check out
the \*Qshow\*U command.
.s1
Note that planes first appear at 10% efficiency.
10% of the listed hcms/lcms/crew must be in the airport in order to
build the plane. (typically hcms, lcms, and mil (crew))
In order for the plane to gain efficiency, it needs
hcms/lcms/mil, as ships and land units do.
As time passes, and as long as there are \*Qavailable work units\*U in the
airport at which the planes reside (to work on the planes), they grow to
100% efficiency.  A plane is not capable of leaving the ground until
it has reached 40% efficiency.
.s1
The work required to add a point of efficiency to a plane is 
.s1
.NF
(20 + (lcm_to_build + 2 * hcm_to_build))/100
.FI
.s1
Planes will also gain efficiency in non-airport sectors, but at only 1/3rd
the normal rate.
.s1
If the CARRIER_WORK option is enabled, planes on carriers will also gain 
efficiency. The amount of work available is based on the carrier's crew,
and the rate is the same as a non-airport sector.
Repairs at sea do not use any lcms/hcms/mil, but may not push the 
efficiency of a plane over 80%.
.s1
Once you have reached tech level 290, you are no longer allowed to
build planes that have tech level below 151.

.LV Expert
.SY "collect "
The collect command is the loan-shark's delight!
Through the collect command overdue loans can be \*Qcleared up\*U.
.s1
If you should find that you have a problem debtor who refuses
to pay up on your kind loan you can always seize one or more
of his/her sectors.
Perhaps the mere threat of a collection on
someone's capital may do the trick!
.s1
To settle up accounts on overdue loan #9 you would type:
.EX collect 9
The program would then ask which sector you would like to claim
as just and rightful compensation for the outstanding debt.
.NF
What sector do you wish to confiscate?
.FI
To which you reply with the coordinates of a sector owned by your
debtor to which you are adjacent.
Any adjacent sector includes any sector you have that borders the
sector you wish to confiscate.
.s1
The program then paws over the sector and assesses its value:
.NF
That sector (and its contents) is valued at $2345.00
.FI
If the amount you are owed exceeds this amount the sector
becomes yours!
If the value of the sector is close enough to the
amount you are owed the debt is considered to be repaid.
.s1
Any che in the area are left alone.  Thus, if the original
owner takes the sector back over, the che would continue their
battle against the original owner, not the new owner.
.s1
In addition, ships, land units, planes and nuclear stockpiles are
not collected.  Those remain the property of the owner of the sector.

This command allows you to consider accepting a loan or treaty
offered by another country.
.s1
The program will list the various terms of the loan or treaty
under consideration and ask for your decision
as to whether to accept the terms, decline them,
or postpone making a decision.
.s1
If you accept a loan,
the money is immediately credited to your account
and the time period of the loan starts.
If at the time of your acceptance,
the lender does not have sufficient funds the size of the loan
will be diminished to fit the lender's cash on hand.
.s1
If you accept a treaty,
it goes into effect immediately but the time period of the treaty
is calculated based on the offer date
rather than the acceptance date.
.s1
Loan offers are withdrawn if not accepted within a number
of days equal to the proposed loan's duration.

populace to become uncompensated workers -- about 10%. Land units
count toward this at a value equal to the number of mil required

GOING TO WAR
.s1
(Note: the following stuff is only in effect if the SLOW_WAR option is selected)
With the SLOW_WAR option in use, you cannot attack the land of someone you are
not at war with. When you declare war on
someone, your relation goes to \*Qmobilizing\*U. You still can't attack them.
After the next update, your relation goes to \*Qsitzkrieg\*U, and you still
can't attack them. After the NEXT update, you're at war with them, and anything
goes.
.s1
If someone is \*Qmobilizing\*U or in \*Qsitzkrieg\*U, or at war with you,
and you
declare war against them, your relation is set to be the same as theirs, so
there is no way to gain any advantage through this stuff. It just means that
you can't sneak-attack people.
.s1
The first person who declares war pays $1000. Return declarations are
free.
.s1
There is an exception to the SLOW_WAR restrictions. If you are listed as
the old owner of a sector, you are still allowed to attack it. This is to
prevent someone from declaring war with you, taking some sectors, then
declaring neutrality before you declare war. (Assuming you didn't notice
their declaration of war)

Also, if the SNEAK_ATTACK option is enabled, you make make one attack upon
someone you're not at war with. You'll pay $5K for the privilege, however.
Once the sneak attack is over (win or lose), war is automatically declare.

The direction must be specified as one of the six direction characters,
(usually `y' `u' `j' `n' `b' or `g'), the \*Qno-direction\*U character,
(usually `h').  If no direction is specified, then the direction will
not be changed for that sector.

The active reserve provides a pool of available military
for a small salary (usually the same amount generated by a civilian)

sectors to be one particular thing and don't want to
be asked on each one you can type something like:

Normally, each point of efficiency added costs you $1. Some sectors

it gives all your sectors back to The Deity,
pays off any debts that it can,

.NA distribute "Establish distribution destination sector"
.LV Basic
.SY "distribute  "
The distribute command is used to specify the way that goods will
travel during an update.
Each sector is allowed to have one and only one
\*Qdistribution sector\*U (a warehouse or road, typically).
Subsequent distribute commands
will replace the existing distribution sector.
.s1
For example,
.EX distribute 2,0 8,4
.NF
highway at 2,0 delivers to 8,4. 
Distribution sector? 7,-1
highway 2,0 new path distributes to 7,-1 (cost 0.200)
        Current best path is 'gguh'
.FI
This command changed the distribution path for sector 2,0 from
a warehouse at 8,4 to a warehouse at 7,-1. The cost is the mobility cost
to move 1 normal-weight unit from the sector to the warehouse.
.s1
DISTSECT is a normal empire sector specification. During the update,
empire will determine the cheapest existing path to the distribution
sector, and use that. (Note that the mobility cost for the path used
during the update could
be different than the cost reported to you when you use the distribute command,
if you have re-designated sectors, or sectors were captured, etc)
Again, it will use the cheapest path available AT THE TIME OF THE UPDATE.
.s1
You may also use '.' or 'h' to specify no distribution sector.
.s1
.EX dist 2,0 .
.NF
Distribution to and from 2,0 halted.
.FI
.s1
The command will warn you if there is no existing path completely
owned by you, and also if the path does not end at a warehouse.
It is not required that the distribution path end at a warehouse,
but it is required that you own all the sectors that the goods
will travel along.
.s1
.L "Distribution & the Update"
.s1
One of the last things that takes place during the update, after all growth,
production, delivery, etc, distribution takes place. (The only thing that
really happens after that is mobility increases) Each sector may have
product
thresholds and a distribution sector. A threshold is a target level for a
particular commodity, like food. So, if the food threshold for a sector is
100, it will try to maintain 100 food there. If it has more than 100 food,
it will export it to its distribution point. If it has less than 100, it
will try to import food from the distribution point to reach 100.
.s1
During the distribution phase of the update, all sectors (going left to
right, top to bottom) first export excess
commodities, and then (again left to right, top to bottom)
import needed commodities.
.s1
In order to either send things to or get things from a distribution sector,
you must own the distribution sector, and there must be a path of owned
sectors to it. In order to export something from a sector, you must have
military control of the sector. In order to import something from a
distribution sector, you must have military control of the distribution
sector. (Military control is defined as having mil in the sector equal
to at least 1/10th the number of unconverted civilians there. Units count
as if they were straight mil, i.e. a 100% unit that contained 50 mil would
count as 50 mil for the purposes of control)
.s1
Mobility is used from the sector when sending \*Qto\*U the distribution sector.
When getting something \*Qfrom\*U the distribution sector, mobility is paid
by the distribution sector.  See \*Qinfo Mobility\*U for an
explanation of mobility costs.
.s1
.L Amount
.s1
The amount is determined by the threshold, as explained above.
Use the \*Qthreshold\*U command to specify what goods
will flow to and from the warehouse.
.s1
.L "Finding sectors with not dist point set"
.s1
If you want to find sectors with no distribution point set, use the 
xdist and ydist selectors:
.s1
.EX level # ?xdist=xloc&ydist=yloc
.s1
This finds all sectors that have themselves as a distribution point.
.s1
.L "Distributing civilians"
.s1
When distributing civilians, no distribution point will ship out its
last civilian, regardless of thresholds set in sectors using it as a
distribution point.

or ship(s) FROM which you are firing, (, , or ).
It will also prompt you for targets for each sector/unit/ship firing, if you
did not specify the target on the command line.
.s1
The only sector that may fire is a fortress,
which must be at least 5% efficient, have at least two military for a
firing crew,
at least one shell to fire,
and a gun big enough to reach the victim location;
range is equal to (7 * ((tech+50)/(tech+200)). If the
fortress is at least 60% efficient, it gets a +1 range bonus.
A fortress firing uses 1 shell.
.s1
Note that forts cannot fire if the NO_FORT_FIRE option is enabled.
See info \*QOptions\*U for more info.
.s1
Any military ship may fire as long as it has
at least one crew (which must be military, not civilians),
at least one gun,
at least one shell (or shells within supply range),
and has at least 60% efficiency.
A ship's gun range is its firing range,  as  shown  by
the show command, divided by two, times ((tech+50)/(tech+200).
A ship uses one shell per two guns firing.
.s1
Any land unit may fire as long as it has
at least one military,
at least one shell (or shells within supply range),
and has at least 40% efficiency.
A land unit's gun range is its firing range, as shown by the show
command, divided by two, times ((50+tech)/(200+tech)).  A land unit
uses the amount of ammo, as shown by the lstat command, each time
it fires.
A unit with less shells than its ammo requirement will do
proportionately
less damage.
(See \*Qshow\*U for firing ranges)
.s1
Forts, land units, and non-depth-charge-equipped ships
 cannot hit submarines on the high seas.
The only way to fire on a submarine is to have a depth-charge-equipped
ship drop a depth charge on it, costing two shells.  (Note you can
also hit subs using ASW planes or subs which have sub-torp capability.)
.s1
The program then prints a satisfying \*QKaboom!!!\*U and,
assuming you were in range, inflicts damage.
.s1
Ships lose mobility points equal to 1/2 the cost they would
pay to move 1 sector for each shot fired. (If the NOMOBCOST
option is in use, ships pay no mobility for firing.)
.s1
The damages inflicted vary with efficiency of the attacker,
the size of the guns
(battleship guns are four times as big as patrol boat guns),
the number of guns fired (7 being the useful max for forts),
and the armor of the victim.
Land sectors take damage depending on their defensive strength.
Use the command 'show sector stats' to show defensive strengths.
The higher the defensive strength, the less damage the sector
will take.

.FI
Note that the shell did about 13% damage in the sector.

The player could have typed:
.EX fir sect #0 ?des=f 34,18

In that case, ALL forts in realm 0 would have fired on sector 34,18.
.s1
If the sector fired on is a fort with guns and shells it will fire back
with approximately the same damages (assuming it has the range).
.s1
Also, any friendly forts, units, or ships within range of the attacker
will return fire, including those belonging to allies, if the allies
are at war with the attacker as well.
.s1
If a ship fired on has guns and shells it will fire back AND
any other ships, units, or forts of the same nationality that are in range
will also fire on you.
.s1
All return fire is split evenly over all attacking sectors/units/ships, and is
adjust by the ratio of defending things to attacking things.
.s1
As a change from the original fire command, with multi-fire enabled,
you will not return fire on yourself.
.s1
IMPORTANT NOTE: Gun ranges, both on offense AND defense, are somewhat random.
If you have a range of 4.16, you can always shoot to 4, and have a 16% chance
of being able to fire at range 5...

.NA flash "Send a message directly to a friend's terminal"
.LV Expert
.SY "flash  []"
.s1
The  argument is either the number or name of
the recipient nation.
.s1
flash allows instant communication between friendly nations.
flash has two different syntaxes.  You can either send your friend a one
line message as in:
.EX flash Foobots Hi there, I'm back from lunch
.s1
Or you can send a multi-line message:
.EX flash Foobots
.NF
> Hi there.
> I ate Fodderland for lunch.
> .
.FI
Note that you can end a multi-line flash with either a '.' (period)
on a line all by itself, or by hitting ^D on a line by itself.
Note also that all messages are truncated to 60 characters long!
.s1
If you do not wish to receive any flash messages from your friends,
then you can temporarily turn the feature off by typing "toggle flash".
.s1
Note that if the person you are flashing is allied to you, you will
be informed if they are not logged in or not accepting flashes when you attempt
to flash them.  This only works when *they* are allied with you, since
you would normally see them logged in or not using "players"

.NA fleetadd "Designate members of a \*Qfleet\*U"
.LV Expert
.SY "fleetadd  "
The fleetadd command is used to specify the fleet groupings
of your ships.
.s1
.EX fleetadd  
In the syntax  is the alphabetic character to be used as the
fleet designation.
This character can be chosen from the set of
upper or lower case a-z and tilde (~).
The pseudo-fleet specification tilde
specifies all ships not currently in any fleet.
.s1
The specification of ships, ,
can have one of several syntaxes:
.NF
example     meaning
-------     -------
23          ship 23
2/14/23     ships 2, 14, and 23

~           all ships currently in the \*Qnull\*U fleet
2,3         all ships in sector 2,3
-1:3,0:2    all ships in the square area bounded by -1,0 & 3,2
.FI
All fleets, (with the exception of the `~' fleet),
are limited to some maximum size
and you will be informed how many ships can be added
when this command is run.
.s1
Having ships organized into fleets can be very helpful in
loading, moving, etc.,
in that fewer commands are required to perform these commands
on groups of ships if they can be specified by fleet number.
.s1
Note that you can remove ships from a fleet by adding them to
the `~' fleet.  e.g.
.EX fleetadd ~ A
This command would purge all ships from fleet `A'.

The \*Qfly\*U command is used to move planes and commodities from
the starting sector(s), and ending up in the target sector.
.s1
 represents a list of planes which are to travel
to the target sector.
Only planes which are provided with gas, and have sufficient mobility will
be successfully selected for the mission.
.s1
 represent a list of fighter planes which are capable of escorting
the transports all the way to the target.
To be selected, escorts must have fuel and mobility.
.s1
 represents an assembly point, where all of the planes in the
mission meet before proceeding on to the target sector.
The assembly point must be owned by you, and must not be more than
four sectors away from any of the planes selected for the mission.
.s1
 is the name of a commodity which is to be carried along
on all of the planes which have a transport capacity.
If nothing is specified, then nothing will be carried.
.s1
Route is a normal empire path specification. You may also give a 
destination sector on the command line, or at any time while giving
the route, and empire will use the best path from the current sector
to the desired destination sector.
.s1
When getting a path interactively, empire will show you the information
you have (from your bmap) concerning the current area, to help you plot
your course.
.s1
If the transports stray over enemy territory, then they will be
intercepted and shot at just like any other mission.
If the destination sector is not an airport, then all planes in
the mission must have VTOL capability.
.s1
Note that a plane must be at least 40% efficient before it can leave
the ground.

.NA follow "Cause one ship to automatically follow another"
.LV Expert
.SY "follow "
You use the \*Qfollow\*U command to get a ship to use the same
sailing path as another ship.
At each update, ships with a sailing path \*Qautonavigate\*U along
the path that was set for them, and ships that are set
to follow that ship will also be navigated along the same
path.  Telegrams notify you of arrivals
or problems encountered while attempting to follow the path.
.s1
Radar operates continuously as the ship moves along the path, constantly
adding sector information to the known world map.
.s1
Ship movement is performed before mobility is increased.
This insures that after the update, ships with a sailing path will still
have some mobility so that you can always manually navigate
to some extent.
.s1
You may follow any ship which is owned by you or a friendly country.

.NA fortify "Fortify a land unit"
.LV Basic
.SY "fortify  "
The \*Qfortify\*U command is used to make units dig in and
make themselves harder to damage. The maximum amount of
fortification is the same as the maximum amount of mobility
a unit can have. (The version command will print this info).
Each point of mobility used increases the fortification value by one.
.s1
A fully fortified unit is twice as hard to hurt as it normally
would be, and is twice as strong on the defense.
.s1
Units fortifying in a sector containing an engineering unit
are better at it. Experiment and find out.
.s1
If a unit moves or retreats, it loses all fortification value.
A unit that reacts to defend a sector, on the other hand, does NOT
lose its fortification unless it is forced to retreat. It receives
the fortification bonus in combat, and is still fortified when it
returns to its original sector after the battle.
.s1
Note that fortification will not help a unit fight Guerrillas in
an occupied sector (see info Guerrilla).  Also note that fortifying
a unit does not affect it's mission status.

.NA fuel "Give fuel to a ship/unit"
.LV Basic
.SY "fuel    []"
The fuel command carries out the fueling of ships and units.
The ship(s) must be in a harbor and
the harbor must be at least 2% efficient.
Land units may be in any sector.
Alternatively, you can fuel at sea using an oiler, which is
any ship with the oiler ability. (Note: if you are in a harbor,
you can't fuel from an oiler, you must use the harbor)
.s1
Ships and units can be fueled by either petrol or oil, with petrol being
used first. 1 unit of petrol = 5 fuel units. 1 unit of oil = 50
fuel units. Each ship or unit, in turn, will attempt to take on the 
specified amount of fuel. Petrol/oil will be used for each ship or unit,
the amount being rounded up individually. For example, if you have
a harbor with 50 fuel in it, and you tell a ship with a 50 fuel
capacity to load 50 fuel, it'll use 1 oil. If you tell it to load
*1* fuel 50 times, it'll use *50* oil, with the round-up making
it use 1 oil each time. The solution, of course, is to not load
fuel in tiny, wasteful amounts. 
.s1
Each update, ships and units use fuel to make mobility points. To produce
10 mobility points requires the number of units of fuel listed
for the ship or unit in the capability list. (see info show)
(This number is usually 1, but may be more). If the number is a 0,
the unit does not use fuel.
.s1
If the ship or unit has no fuel,
it will attempt to get fuel using the supply procedure (see
info supply). It will try to use first petrol, then oil, until it has enough
fuel to get full mobility.
If it can't get fuel by using the supply system, it won't get mobility.
.s1 
See \*Qshow\*U for a table of the maximum amounts of
fuel that can be carried on each type of unit or ship.
.s1
You can fuel friendly ships, but must fuel them one at a time, by number.

The \*Qharden\*U command is used to install missiles
into protective silos which can prevent their destruction
during a nuclear or non-nuclear
attack.
Each successive \*Qharden\*U command
will add to the current hardness level of the missile in question.
.s1
Each point of hardening uses one unit of heavy construction materials,
and costs $5.

.NA launch "Launch missiles or satellites"
.LV Expert
.SY "launch "
The launch command is used to launch missiles (or satellites)
from sectors or submarines owned by you.
.s1
There are 5 classes of missiles:
.NF
1. "marine" missiles may only be fired at ships.  They may be given
   "interdiction" mission.  When interdicting ships, "marine" missiles
   will keep launching until the entire enemy fleet is sunk.
2. "tactical" missiles (without "marine" capability) may only be fired
   against sectors.  They may be given missions.  If they fire on a
   mission, then only enough missiles will fire to cause 100 damage.
3. "intercept" missiles can not be launched.  They automatically
   intercept planes.  You can increase their reaction radius by giving
   them an "air" defense mission.
4. "a-sat" missiles will automatically attempt to intercept AT_WAR
   satellites which are launched into orbit within range.
5. "abm" (anti-ballistic-missiles) will automatically attempt to
   intercept incoming "tactical" (non-"marine") missiles.

As well, there are "satellites" which are like missiles in that they
can be launched, but unlike missiles in that they don't get destroyed
as soon as they are launched.
.FI
.s1
In certain cases, a missile will require petrol or shells to be in the
sector before it can be launched.  See 'show plane stats' to find out
how much fuel the missile requires.  The 'load' value in 'show plane
stats' specifies how many shells the missile requires.  Note that if
the missile is armed with a nucelar warhead, then it does not require
any shells.
.s1
Once a satellite has been launched, it can not be moved again.
.s1
Note here that it is much safer to use 100% missiles than those which
are less efficient,
and missiles below 60% cannot be launched.
.s1
The formula for the chance that a missile hits its target is in
\*Uinfo Hitchance\*U.
.s1
Of course, things don't always go as planned!
.s1
Note that when you are first asked for the target sector
you can chicken out by hitting ^C
(or your favorite abort character).
.s1
In the case of non-marine tactical missiles, if there are any HOSTILE
abm's within range of the target sector, then two of them will fire in
an attempt to intercept the incoming missile.  
.s1
Similarly, two AT_WAR a-sat's will attempt to intercept any satellites
you attempt to launch within their range.  Also, if the sector you are
launching your satellite at is owned by a non-allied country, then
they will get a telegram informing them of the positioning of the
satellite.  See below for details of a satellite's orbit path.
.s1
When launching missiles, there is a 
% chance equal to (5 + 100 - efficiency) * (1 - techfactor) that the
missile will blow up on
the launching pad instead of launching. If that happens, then there is
a further 33% chance that the warhead it is carrying (whether it be
conventional or nuclear) will detonate.  (Note that nuclear warheads
will only detonate in this way if the option NUKEFAILDETONATE is enabled).
A nuclear warhead exploding on the launch pad will do the normal
amount of damage, but a conventional missile will only do half damage
to the sector or ship it is being launched from.
.s1
Missiles launched from submarines are anonymous. The victim
is not notified of the identity of the launching country.
.s1
Missiles on interdiction mission have the same chance of hitting and
do the same damage as if they were launched by hand.  Also, any
nuclear armed missiles will detonate if they launch on an interdiction
mission.  You specify whether the nuclear warhead will airburst or
groundburst when you arm the missiles (see info arm).
In order to better destroy missiles on the ground (or in their silos),
the ground-burst technique is used.
Ground-bursts are much less effective against large area targets,
but do massive damage to the sector it impacts,
possibly knocking out hardened missiles
before they can be used against you.
In the parlance of nuclear targeting doctrine,
this is known as \*Qcounter-force\*U targeting.
Air-bursts are used in order to kill large numbers of civilians,
to knock out industry (by flattening the factories),
to take out lightly armored military targets in a large area,
and to generally wreak havoc.
Nuclear strategists call this a \*Qcounter-value\*U technique.
.s1
See Also \*QOn Thermonuclear War\*U by Herman Kahn.
.s1
If the ORBIT option is enabled, then when you launch a satellite, you
will be asked "Geostationary orbit?".  If you answer "y", then your
satellite will stay where you launch it.  If, however, you answer
"n", then your satellite will orbit the planet.  When a satellite is
"orbiting", it moves along 5% of a geodesic path every
update.  The path the satellite follows looks like this:
.NF
+----+
| /  |
|/   |
|   /|
|  / |
| /  |
|/   |
|   /|
|  / |
+----+
.FI

That is, start in the middle, move northeast until you hit the edge,
then continue from the west edge near the top and go northeast until
you go off the top of the map, then continue at the bottom going
northeast until you go off the eastern edge again, and continue from
the western edge near the bottom until you get back to the centre.
That is the path of satellites which are _not_ in geostationary orbit
(geo-stationary means stay in the same spot over the planet).
.s1
If a foreign satellite moves over your territory durring an update, then you
will get a message like "Fodderland satellite spotted over 12,24" as a
part of your update BULLETIN.

.s1
.SY "lload   "
In the first form,
the amount argument specifies the amount of the given commodity
you wish to load on each unit specified.
Amounts greater than that allowed will be truncated to the
maximum possible. Amounts less than 0 indicate that you want to
make the unit/army have that amount. If the unit/army has less
than that amount, more will be loaded. If the unit/army has more
than that amount, the commodity will be unloaded. For example,
.s1
.EX load food 3 -100
.s1
will cause unit 3 to load or unload food so that it has 100.
If it had 120 food, 20 would be unloaded. If it had 50 food, 
50 would be loaded.

.NA lmine "Mine a sector with an engineering unit"
.LV Expert
.SY "lmine  "
This command causes a unit with the engineering ability
to lay mines in a sector. (see \*Qinfo Unit-types\*U).  If you ask to
lay more mines than the unit is carrying, then it will attempt to keep
resupplying itself until all of the mines have been laid.  It costs
1 mobility point per mine laid, so an engineer with 20 mobility can
lay a maximum of 20 mines.  The 'strength' command will list how many
mines you have put in each sector.
.s1
See \*Qinfo Hitchance\*U for the chance of something hitting a land mine.
.s1
If a defender in land combat has land-mines in the sector, he
receives a bonus to his defense. See info \*Qattack\*U for more information.
If the attacker has engineering units with him, the bonus is less.
.s1
In the command syntax
 is the number of one of your units and  is
the number of mines you wish to lay.
That number of shells, (assuming you've got them),
will be dropped in the sector that unit occupies,
magically becoming mines.
.s1
You need not fear mines in sectors that you are the old owner of. This
is normally all your sectors. When you capture a mined sector, however,
you will need to worry about those mines until you become the old owner
of that sector. Once you are the old owner of a sector (i.e when you
get the message "Sector x,y is now fully yours."), you have the mines located,
and will no longer hit them.
.s1
If you are in a captured sector, and the original owner attacks, you will not
get the mine bonus (as he knows where all the mines are)
.s1
Mines can only be removed safely by a unit with the engineering ability.
(Other units can remove them by hitting them, but...)
Engineering units moving through a sector with unlocated mines will
attempt to remove them.  The number of times each engineer sweeps for
mines is equal to 2 times the number of mines it can carry.  The
chance of the engineer finding a mine on each sweep is equal to 50%
times its 'att' value (see show land stats).  If an engineer sweeps
more mines than it can carry, then it will drop the rest as shells
into the sector.

make the ships have that amount. If the ships have less
than that amount, more will be loaded. If the ships have more
than that amount, the commodity will be unloaded. For example,
.s1
.EX load food 3 -100

.s1
.SY "load land  "
In the third form, 
where you say \*Qland\*U instead of say \*Qciv\*U, a unit
is loaded onto a ship. Multiple units may be given. Some may
not be loaded, if there is not enough room. (Note that planes on
land units on ships can't be used, and units on ships generally can't
do much, like firing, marching, etc).  When loading a land unit onto a
ship, the unit will check to see that it is in supply before stepping
on deck.  If it isn't, then it will try to resupply itself (see info
supply) and if it is not able to do that, then you are issued a
warning.  Sailors don't like to go to sea without supplies.

This range is dependent on both the visibility of the ship

(see \*Qinfo Ship-types\*U)
Submarines at sea are a special case - they cannot be seen by simply looking
out from a ship!  In order to detect subs at sea, you need to use sonar.
Submarines have a very limited range for what ships they
can see using their periscope--they can usually only see ships in the
same sector.  However, all ships (including subs) which are docked in
a harbour are visible to all ships (including subs) in adjacent sectors.

.NA lost "Report lost items"
.LV Basic
.SY "lost"
The lost command displays all lost items currently in the

.s1
All lost items are timestamped at the time they were lost.  If
you had a previously lost item in the database, and then build a
new item of the same type with the same id, or regain an item of the
same type with the same
id, it is removed from the database.  This is done because the new item
will now show up in the other dump commands, and is no longer lost.
.s1
Lost items are kept in the database for 48 hours (default) but may
be kept longer at the deity's discretion.  Also, issuing the lost
command does not remove items from the database.  That is where the
timestamp functionality becomes important.
.s1
While the lost command does not take any arguments, it does
take the standard syntax for selecting information.  
(see \*Qinfo Selector\*U).
.s1
A typical usage might be:
.EX lost ?timestamp>854954677

The retreat command allows you to examine or modify the retreat 
paths and conditions of your ships or units. The following description
is for ships. Land units are exactly the same, except of course that
some of the retreat conditions (being sonared, depth charged, etc) don't apply.
.s1
The  and  arguments are provided to specify which
ships to view or give orders for. If a fleet designation is given when
specifying orders, the orders apply to all ships within that fleet.
.s1
Retreat expects an argument.  To see every ship you own, give it
the argument '*', or type "retreat *".
.s1
The report format contains the following fields:
.s1
.in \w'shiptype\0\0'u
.L shp#
the ship number
.L shiptype
the type of ship; \*Qpatrol boat\*U, \*Qsubmarine\*U, etc,
.L x,y
the ship's current location (relative to your capital),
.L flt
the fleet designation letter (set by \*Qfleetadd\*U command),
.L path
the ship's current retreat path.
.L as_flt?
whether or not the ship's retreat path is a fleet retreat path
.L flags
what conditions the ship will retreat under
.in
.s1
For example:
.EX retreat *

.L Overview
.s1
A player may give retreat orders for a ship or a fleet. Retreat 
orders include a set of conditions that determine when the fleet/ship
will retreat, and a path that the fleet/ship will follow. When a condition
is met for a particular ship, the \*Qas flt?\*U field is checked. If it
is Yes, then every ship in that fleet with fleet retreat orders retreats
along the specified path. If it is no, then the retreat orders apply to 
that ship only, and only that ship retreats.
.s1
When a ship is added to a fleet, it is given the retreat orders of that
fleet, if any exist.
.s1
Retreat orders are wiped when a ship navigates.
.s1
Retreat conditions at present include:
.nf

		Condition	Meaning
		I		Retreat when the ship is injured,
				i.e. whenever the ship is damaged
				by fire, bombs, or torping.
		T		Retreat when a sub torpedos or tries
				to torpedo the ship.
		B		Retreat when a plane bombs or tries
				to bomb the ship.
		S		Retreat when the ship detects a sonar
				ping.
		D		Retreat when the ship is depth-charged.
		H		Retreat when helpless. A ship is helpless
				when it is fired upon, and no friendly
				ships/sectors (including the ship itself)
				are able to fire back at the aggressor.
		C		Clear the flags

For example, if the battleship above was fired at, it would attempt to
retreat 2 sectors, jj, using the normal amount of mobility for moving
2 sectors. It would then look like:

.NA march "Move a land unit or units"
.LV Basic
.SY "march  "
The march command is the \*Qmove\*U command applied to land units.
You can control one unit or an entire army with it.
.s1
Land units may only move into sectors you own, sectors of countries
you are allied with or deity-owned sectors with 1 exception.  Spies.  Spies
may move anywhere, with a chance of getting caught.  See "info Spies" for
more information.
.s1
If you are moving an army and the lead unit stops, the army stops;
(the lowest numbered unit is always considered the lead unit).
.s1
The program will prompt with the mobility of the lead unit,
the minimum mobility value for the army, and the current sector
coordinates in the form:
.NF
<57.0:23.5: -6,4>
.FI
which means the lead unit has 57 mobility units,
some other unit in the army has 23.5 mobility units and
the lead unit is in sector -6,4.
You may indicate the direction you would like the army to move
by typing a string of letters consisting of any combination of the
following:
.NF
y  for up-left
u  for up-right               y    u
g  for left                    \\\\  /
j  for right               g  --  --  j
b  for down-left               /  \\\\
n  for down-right             b    n
r  for radar
l  for lookout
m  to sweep landmines
h  for end of movement
.FI
.s1
The radar option will cause the lead unit to use it's radar, if any.
You may also give a unit number or army or group of units on the same
line: "r 12/13/14/73"
.s1
The lookout option works in the same way as radar, i.e. it will cause the
lead unit to do a lookout.
.s1
Note: the lookout and radar commands use BTU's, just as if you'd typed them
separately from the command line.
.s1
You may also use the 'm' command to have engineers in the marching
group search for mines in the current sector. Example: "m 12"
.s1
Since the  can be specified in the command line,
simple unit movements are often typed as a single line, such as:
.EX march 19 jjjh
.s1
Or some movements may be done partly on the command line and partly
interactively:

.EX march 18 yy
.NF
<112.7:112.7: -4, -2> l
Your capital 100% efficient with 549 civ with 10 mil @ -5,-3
Your highway 100% efficient with 549 civ with 0 mil @ -4,-2
Your harbor 100% efficient with 549 civ with 109 mil @ -3,-1
<112.7:112.7: -4, -2> yh
war band #18 stopped at -5,-3
.FI
.s1
You may also simply specify the destination sector
on the command line. In this case,
empire will set the path to be the cheapest path (in terms of
mobility) that currently exists. The unit(s) will move to the
destination sector, and then ask for more input.
.s1
For example,
.EX march 18 -6,-2
.NF
<104.2:104.2: -6,-2> h
war band #18 stopped at -5,-3
.FI
.s1
Note that if you are marching multiple units, you may only specify a
destination sector on the command line if all the units start in the
same sector.
.s1
See "info Mobility" for the mobility cost to march land units.
.s1
At the update, units with negative mobility have their mobility halved
before new mob is added. For example, in a game where units got 32 mob
per update, a unit with -100 mobility would have -18 after an update.
(-100/2 = -50 + 32 = -18) This helps inefficient units be not quite as
slow.
.s1
Moving a unit through a sector that has been mined
introduces a chance of mines/(mines + 50) that you will be damaged.
Units with engineering capabilities can remove up to five mines per
pass through a sector (indicated by the message \*QSweep...\*U).
Such units also take 1/2 normal damage from mines.
See info lmine for more details.
.s1
Hostile land/sea/air units may fire at/bomb your units, if they're
on interdiction missions (see info mission).  If your enemy has a
stack of missiles on interdiction mission, then they will
automatically fire one after another until 100 damage has been done.
Missiles and pinbombers have a 100% chance of hitting their target
(provided they make it through plane/missile defenses).  Collateral
damage will be done to the sector that the units were marching into.

.NA mine "Drop sea mines from a ship"
.LV Basic
.SY "mine  "
This command drops mines in the sea and is functional
from ships with mine-laying capability (see \*Qinfo Ship-types\*U).
.s1
See \*Qinfo Hitchance\*U for the chance of a ship hitting a mine.
.s1
In the command syntax
 is the number of one of your ships and  is
the number of mines you wish to drop.
That number of shells, (assuming you've got them),
will be dropped in the sector that ship occupies,
magically becoming mines as they hit the water.
.s1
Mines can only be removed safely by a minesweeper.
(Other ships can remove them by hitting them, but...)
Planes with the 'sweep'
ability can clear mines by flying recon missions through
mined sectors, with each passage through the sector possibly
removing some mines.
.s1
Ships of tech 310 or higher can detect mines with their sonar.
See \*Qinfo sonar\*U for more information.
.s1
Harbors and sea sectors under bridge spans can be mined.
Your ships will automatically avoid these mines when passing through,
(and your minesweepers will not not pick them up).
.s1
Note that the sector is checked for possible mine hits
only when a ship moves into it;
thus, a ship may safely drop mines in a sector and then move out.
On the other hand, the mines know no allegiance,
so moving back into a mined sector is foolish at best
unless it is a harbor or under a bridge span.
.s1
Mines in the same sector as a bridge that collapses are cleared.

.FI
You may also use 'q' (query) to check on
the mission of something, or 'c' (clear) to wipe the mission of a land
unit/plane/ship.
.s1
GENERAL CONCEPT
.s1
Missions are things that your planes/land units/ships can do automatically, such
as bombing/shelling. You assign a unit to a mission, and whenever the right
conditions occur, the unit attempts to perform its mission. Note that missions
don't allow a unit to do anything it normally could not do, they simply allow
them to do it in an automatic fashion. In some cases, units performing missions
might not be as 'smart' as they would be if you were operating them personally.
That's the price you pay for having automatic defenses.
.s1
.L "IMPORTANT NOTES"
.s1
Missions can occur during updates.  (Interdicting ships using "sail"
or "order").
.s1
Artillery units less than 20% efficient will not fire.
.s1
Planes flying missions will be intercepted normally. (i.e. if you fly
over enemy territory, you'll get intercepted. Any mission except air
missions may also be intercepted by planes on air defense missions)
.s1
Planes of less than 40% efficiency will not fly missions.
.s1
Planes assigned to missions are \*QNOT\*U eligible to intercept
normally. For example, if a fighter is assigned to an escort or air-defense
or interdiction or support mission, it will \*QNOT\*U rise to intercept
an intruding enemy plane. (planes on air-defense missions will intercept
planes flying in their op-area, in accordance with the air-defense mission,
but will not intercept one outside their op-area, even if it is within
their normal range. Be sure you understand this before using plane missions.)
.s1
Nukes on missiles or planes flying missions DO detonate.
.s1
"marine" missiles will keep launching to interdict ships until all of
the valuable ships in the fleet are sunk.  A "valuable" ship is one
which cost at least $1000 to build or can carry land units or planes.
For each new missile launched, the most valuable ship according to
(cost to build) * efficiency is targeted.
.s1
Non-marine missiles will keep firing
on a sector until 100 damage is done.
.s1
OPERATIONS SECTORS
.s1
Some missions require the designation of an 'op sector', short for operations
sector. This is the center of an area that the mission is focussed on.
The op sector may be any sector that is within the unit's range.
(Firing range,
for ships & land units, flying range for planes, changeable with rangeedit).
The unit will exert influence in a radius around the op sector.
By default, the radius will be as large as possible, i.e. the biggest range
so that the unit/ship/plane could legally act there.)
For example, a ship with a range of 4 could designate any sector up
to 4 away from it as it's op sector, and would affect anything within
4 of it's op-sector, provided it was also within 4 of the ship.
.s1
If a smaller radius is desired, it may be specified on
the command line. If it is not specified, it will not be prompted for.
.s1
The area affected by a unit is known as that unit's op-area.
.s1
If a '.' is given as the op-sector, the op sector will be the location
of the unit.
.s1
Additionally, if the unit's op-sector is the sector the unit is in, and
the unit moves without losing its mission
status, the operation sector will move with it. (Normally, of course, the
only way for a unit on a mission to move is to be carried on a ship, so
this mostly applies to planes on carriers) Thus, a tactical bomber on a ship
could have an op-area centered on the carrier that moved with the carrier.
.s1
Otherwise, if the unit moves without losing its mission status, the
op sector will stay where it was designated.
.s1
For example, suppose that land unit 4 is an artillery unit, range 5,
located at 0,0.
.s1
.EX "mission land 4 int ."
.s1
This would make the unit interdict anything passing within 5 sectors of
its location.
.s1
.EX "mission land 4 int 4,0"
.s1
This would make the unit interdict anything passing within 5 sectors of
4,0, provided it was also within 5 sectors (the unit's range) of 0,0.
.s1
.EX "mission land 4 int 4,0 2"
.s1
This would make the unit interdict anything passing within 2 sectors of
4,0, provided it was also within 5 sectors (the unit's range) of 0,0.
.s1
The op-sector/op-range concept allows you to restrict a unit's area of 
interest to a small, important area, or just let it shoot at anything within
range.
.s1
MOBILITY USE
.s1
When a unit is given a mission, it costs no mobility.  When a unit performs
its mission, it uses the normal mobility costs that it would use to
perform that mission if done by the player.
.s1
A unit stays on its mission until you cancel it, OR the unit acts. Any type
of action not a part of a mission
is sufficient, so marching, navigating, transporting, flying, reconing,
bombing, mining, paratrooping, being attacked, being 
paratrooped on, retreating, etc, will all cause a unit to lose its 
mission status, but the unit could bomb/shell/etc AS PART OF A MISSION, and
still retain its mission status.
Also, land units with a reserve
mission can react to a threatened sector and fight, and (assuming they win)
return to their original sector without losing their reserve status.
.s1
Note that fortifying a unit does not affect it's mission status.
.s1
DEFENDERS
.s1
The defender's planes will intercept planes flying missions.
His ships/forts/units, however, will \*QNOT\*U fire at ships/forts/units
firing on a mission.
.s1
INTERDICTION MISSIONS (ships, planes, land units)
.s1
When giving a unit a interdiction mission, you designate an op sector. From
then on, whenever an enemy (defined as something belonging to a nation which
you are at war with) moves in a sector in that unit's op-area,
the unit will try to shell or bomb it (as appropriate). Almost any kind of
movement, except for distribution movement during an update, and the tiny
amounts moved by the supply routines is enough.
.s1
For example, an enemy land unit marching up to the front would be
shelled/bombed.
An enemy moving commodities around would have the commodities automatically
shelled/bombed. A ship navigating into a sea sector would be shelled or bombed,
depending on it's type (obviously, only depth-charge or ASW capable units would
affect a submarine, and a submarine would only affect things it could torpedo)
In general, units can only affect things they could normally affect. For
example, if the enemy was transporting a plane along a highway, and you had an
artillery unit and a light bomber interdicting the highway sector, the land
unit would fire and the bomber would fly there and bomb, and the total damage
would be applied to the plane being transported. If it was still alive, it
might be moved to another sector, there to be bombed/shelled again (assuming the
new sector was also in both units' op-areas) If a different unit later moved
in, it would be shelled/bombed. This happens as long as the interdicting units
have mobility left.
.s1
Damage done is divided amongst all units/ships/commodities moving. For
example, if 6 ships were moving, and the interdiction mission did 18 pts of
damage, each ship would take 3. 
.s1
Note that only ships with sonar and ASW planes can interdict subs. Also, the
units may or may not detect the subs, so it's kind of random. The sub also
has a chance of escaping the damage, depending on the visibility of the sub.
.s1
Only planes with the 'tactical' ability can fly interdiction missions.
Only planes with 'ASW' ability will fly vs. subs. Planes with 'ASW'
ability will not fly interdiction vs. other types of
ships/planes/units/commods.  Subs have a chance of sneaking through
ASW aircover unnoticed, and ASW planes will respond to any
non-Friendly sub movement.  Depending on the visibility of the sub,
the ASW plane may or may not identify the type and/or owner of the
sub.

Interdiction has no effect on flying planes. Interdiction does not
affect loading/unloading.  It will also cause some damage to the
sector that the commodities were moving into.
.s1
Note also that forts will fire at enemy ships coming within
range. You don't have to set anything for this, it
happens automatically. (Forts firing at enemy ships naving happens before 
ships/planes/units interdicting ships, so if the enemy is using an area a 
lot, a fort will hurt him without costing you mob from planes)
.s1
SUPPORT MISSIONS (planes only)
.s1
A support mission allows your planes to automatically bomb the enemy.
Planes with offensive support missions will bomb enemy sectors that you
attack. Planes with defensive support missions will bomb enemy troops
attacking your sector, adding to your defensive strength. Planes with
support orders will do both.
.s1
When giving a plane a support mission, you designate an op sector. From then on,
whenever a sector owned by the plane's owner (or by an ally of the plane-owner,
if the ally is also at war with the attacker)
in that plane's op-area is
attacked, the plane will attempt to fly to that sector and give ground support,
if it has support or defensive support orders.
.s1
If the plane's owner (or an ally of the plane's owner, if the ally is
also at war with the country attacked)
attacks a sector in that plane's op-area belonging to a
country that the plane owner is at war with, the plane will
also attempt to fly there and give offensive support if it has
support or offensive support orders.
.s1
(see info attack for more information on how support works in land combat)
.s1
Only planes with the 'tactical' ability can fly support missions.
.s1
ESCORT MISSIONS (planes only)
.s1
When given an escort mission, an escort or intercept capable plane will attempt
to escort any plane flying a support or interdict mission from the same airport.
If even 1 plane flies a support or interdiction mission from an airport, all
planes on escort duty at that airport will attempt to escort. Planes with escort
duty will NOT attempt to escort planes taking off from other airports, so it
pays to put your bombing planes and escorting planes together.
.s1
Only planes with the 'escort' or 'intercept' abilities can fly escort missions.
.s1
AIR DEFENSE MISSIONS (planes only)
When given an air defense mission, an intercept capable plane will attempt
to intercept any enemy plane (defined as any plane belonging to a country
you re at war with) flying into its operations area, irregardless
of whether the enemy planes are flying over owned sectors. For example, if
a plane is given an air defense mission with an op area covering some
owned sectors, some sea, some allied sectors, and some enemy sectors, it
would try to intercept over any of them.
.s1
When a plane enters a sector, any planes with air defense missions that are
at war with the owner of the plane will fly there to fight it. 
The air defense planes
encounter normal interception along the way (but do \*QNOT\*U trigger 
more air defense missions, but \*QMAY\*U be intercepted normally).
Once the air defense planes get to the sector,
they fight the plane. Then, if the owner of the sector
is hostile to the plane, still more planes may intercept it.
.s1
.L Example
Groonland wants to run a recon flight over Bannannarama. Joeland has a
jet fighter with an air defense mission and an op-area covering part of
Bannannarama. The 'j' sector belongs to Joeland, and is the base for the
fighter. The 'b' sectors belong to Bannannarama, which has 1 fighter
in the center sector. The 'g' sector belongs to Groonland. Assume that
all countries are mutually at war.
.s1
The Joeland fighter's op area is centered on the 'B', radius 2.

.FI
.s1
The Groonland player enters a path of 'uujjjbgbggh'.
The first sectors entered is sea, and is not in the Joeland
aircraft's op-area, so nothing happens.
.s1
Next, the Groonland plane enters the sector adjacent to Bannannarama.
This is within the Joeland aircraft's op-area, so it flies to intercept.
It takes the shortest path there, and fights the Groonland plane.
Let's say that both take 20 points of damage, and neither aborts.
.s1
Next, the Groonland plane overflies a Bannannarama sector. The Joeland
plane flies there, and is intercepted by the Bannannarama plane. Let's
say that it comes through the fight without being aborted. It then fights
the Groonland plane. After this combat, if the Groonland plane is not
aborted, it may be intercepted again by the busy Bannannarama fighter,
assuming that that plane is still efficient enough, has mob enough, etc.
.s1
A good use of this mission is to provide a wider CAP around a carrier,
so that enemy planes get intercepted several times on the way to the
carrier, rather than just once, in the carrier's sector.
.s1
Another use is to provide air-cover for an ally who has temporarily
lost his planes.
.s1
RESERVE MISSIONS (land units only)
.s1
A land unit given reserve orders has an increased ability to react to enemy
attacks. A reserve unit has its reaction radius increased by 2.
(Note: this is cumulative with the +1 modifier for being at an
efficient headquarters, so a reserve unit at an HQ would have a +3).
In addition, a reserve unit pays 1/2 the normal cost for fighting a battle.
(It still pays the normal cost for moving to the threatened sector)
See info attack for more details on reaction.
.s1
Note that units with a reserve mission retain this status, even though they
move to the threatened sector and return. This is an exception to the normal
rules on losing your mission status. If, however, the land unit is forced to
retreat from the combat (see land combat for details), it WOULD lose its status.
.s1
When a unit with a reserve mission is listed, the op sector is the sector
the unit is in, and the radius is the units maximum reaction radius, including
the bonus for the reserve mission and HQ (if applicable). Note that the unit's
actual radius might be different if it was changed by lrangeedit.
.s1
Note: information gained from planes flying missions is automatically
added to your bmap.

.NA morale "Change the retreat percentage of a unit"
.LV Expert
.SY "morale  "
The \*Qmorale\*U command is used to set the retreat percentage of land
units.
.s1
Normally, a land unit must start making morale checks during combat
when its efficiency is less than or equal to its retreat percentage.
(The chance of failing a morale check is: sqrt(100-effic)%/(men in unit).
Example: a 25 man unit is at 75% efficiency. It's chance of failing is
sqrt(100-75)%/25 = sqrt(25)%/25 = 20%)
.s1
The morale command
allows you to adjust this percentage within a range. If, for example, you
wish only to trade space for time, you could set the retreat percentage
to 100%, meaning that your units would retreat often, but would still slow
the enemy down a bit. Or, you could set your retreat percentage to the minimum,
and make the unit stick around and fight more, but at the cost of more
casualties.
.s1
The maximum allowed value is 100% (i.e. start making morale checks after
any casualties) The minimum values is based on happiness:
.ti 3
(morale_base) - happiness
.s1
"morale_base" is a deity settable variable, which defaults to 42.  When
a unit is first built, it's retreat percentage is set to "morale_base".

The move command is crucial to Empire; it carries out the movement
of civilians, military, ore, guns, shells, food, planes, etc. on land.
Note that you can only move into sectors that you own, so you cannot
take sectors via move.  To take sectors, use the "explore" command,
which uses the same syntax as move.

then display the number of mobility units in that sector,

The \*Qview\*U command shows the sector efficiency
and some of the contents of the sector you are currently occupying.
.s1
Since the  can be specified in the command line,
simple movements are often typed as a single line, such as:
.EX move m 2,0 20 jjjh
Or some movements may be done partly on the command line and partly
interactively:
.EX move c 2,2 18 jj
.NF

.s1
You may also simply specify the destination sector.
In this case,
empire will set the path to be the cheapest path (in terms of
mobility) from the current sector to the destination sector,
if such a path exists.
.s1
For example,
.EX move c 2,2 18 6,2
.s1
.L "Military control"
.s1
In order to move something (other than mil) out of a sector, you must have
military control of the sector. Military control is defined as having mil in
the sector equal to at least 1/10th the number of unconverted civilians there.
Units count as if they were straight mil, i.e. a 100% unit that contained 50
mil would count as 50 mil for the purposes of control)
.s1
.L Mobility
See 'info Mobility' for a description of how much mobility it costs to
move something.
.s1
.L Mines
Note that while moving, you might hit mines. The more stuff you're
moving, the greater the chance of setting off any
mines in the sectors you move through. See info lmine for more details.
.s1
.L Interdiction
Any enemy units on interdiction mission may be triggered by the move
(the more you move, the bigger the chance they interdict).  The
interdiction will damage the goods you are moving, and will also cause
some damage to the sector you were moving into.
.s1
.L "Unhappy civilians"
.s1
Also, when moving unhappy civilians (work percentage less than 100%), 
unhappiness is contagious. If you move even 1 unhappy civilian into a
sector, the new sector's work percentage is set to the level of the
civilian being moved, if that is less than the existing level.
.s1
However, if the NEW_WORK option is enabled, the work percentage of the
destination sector is computed by averaging the incoming civ's happiness
with the happiness of the civs already there. For example, say you move
100 civs with work percentage of 0% into a sector with 100 fully happy
civilians (100% work). If NEW_WORK is enabled, the work would be:
.ti 3
((migrants * their work) + (people at dest * their work) / (total civs)
((100 * 0%) + (100 * 100%)) / (100+100) =  100/200 = 50%
.s1
.L "Plague"
If a sector is infected with the plague, then anything moved out of
the sector will infect the sector that it moves into.  Note that
sectors moved through will not catch the plague.

.SY "mult  "
The mult command allows a nation to set price multipliers
of the goods they are selling.
.sp
The  argument is the number or name of the nation
for which you want to reset the multiplier, and  is
the new multiplier (a floating-point number). If no
arguments are given, you are prompted for them. A carriage return
or incorrect nation at this prompt allows the changing
of all the price multipliers.
.sp
For example, if one nation is a \*Qnice\*U nation,
and another is particularly unfriendly,
the price multiplier for the nice one might be 0.75,
while the \*Qnasty\*U nation might have one around 5.
.s1
The price multiplier affects the price of a nation's goods
to other nations.
Final item price is determined by multiplying the price
of the item at the time of the sale by the individual price multiplier
for the nation buying the item.
You cannot have a price multiplier below 0.05.
.s1
Typical output looks like:
.EX mult

.NA nation "The state of your nation"
.LV Basic
.SY "nation"
The nation report command displays various data about your country.
.s1
The data displayed by the nation command is formatted as a single page
report and should be self explanatory.
For example:
.EX nation
.NF
	MGM Nation Report	Sat Nov  4 15:01:52 1986
Nation status is ACTIVE         Bureaucratic Time Units: 250

Education..........  9.20       Happiness.......  2.01
Technology......... 16.81       Research........  19.82
Technology factor : 30.81%      Max population : 556
 
Plague factor :   1.05%
Max safe population for civs/uws: 427/483
Happiness needed is 4.385283
.FI
.s1
If the RES_POP option is in use, there will be a line that
tells you the maximum number of civs you can have in a sector
without losing them (999 without this option), and the maximum
number of civs you can have in a sector without losing population
growth.
.s1
If the NO_PLAGUE option is not used, you'll also see a line
that has the plague chance for your nation.
.s1
The max safe population is the highest population in a sector
that will NOT forfeit some population growth during an update.
In the example above, if you have 427 civs in a sector, you are
guaranteed not to have more than 556 after population growth.
If you have more than 427, population growth would make you go
over 556, and the excess babies would be eliminated when the
population was reduced to 556.
.s1
If you have at least the happiness mentioned in the last line,
your sector's loyalty won't have a chance to go down. Otherwise,
each update, the chance is the number above - your happiness / 5.0.
For the country above, the chance would be (4.385283-2.01)/5.0 = .475 = 47%
chance that any individual sector's loyalty would go down.

.NA navigate "Move ship or fleet around"
.LV Basic
.SY "navigate  "
The navigate command is the \*Qmove\*U command applied to the sea.
You can control one ship or an entire fleet with it.
.s1
A ship must have at least one crew
(which may be civilian or military,
but not an uncompensated worker)
to be navigated.
When you navigate, you see the hex of sectors around the flagship.
(The lowest numbered ship is always considered the flagship).
.s1
The program will prompt with the maximum and minimum mobility of the
ships in the fleet, and the current sector of the flagship in the form:
.NF
<57.0:23.5: -6,4>
.FI
which means one ship has 57 mobility units,
some other ship in the fleet has 23.5 mobility units and
the flagship is in sector -6,4.
You may indicate the direction you would like the fleet to move
by typing a string of letters consisting of any combination of the
following:
.NF
y  for up-left
u  for up-right               y    u
g  for left                    \\\\  /
j  for right               g  --  --  j
b  for down-left               /  \\\\
n  for down-right             b    n
.FI
Other commands you may type while navigating are:
.NF
M  for map
B  for bmap
f  to change flagship
i  to list ships you are navigating
v  to view oil content and fish
r  for radar
l  to look at land and nearby ships
s  for sonar
m  to sweep mines
h  for end of movement
.FI
.s1
While navigating you may also use radar, sonar, or lookout.
(by entering r, s, or l) By default it will radar, sonar, or 
lookout from the flagship. You may also
give a ship number or fleet or group of ships on the same
line: "r 12/13/14/73"
.s1
You may also use minesweepers in the currently navigating group to
sweep mines. This costs them the equivalent of 1 sector's mobility.
For example: "m 12/13"
.s1
Since the  can be specified in the command line,
simple ship movements are often typed as a single line, such as:
.EX nav 19 jjjh
.s1
Or some movements may be done partly on the command line and partly
interactively:

.EX nav 18 jj
.NF
<112.7:112.7: -4, -2> v
patrol boat #18 on open sea @ -3,-2
<112.7:112.7: -4, -2> gh
patrol boat #18 stopped at -6,-2
.FI
.s1
You may also simply specify the destination sector
on the command line. In this case,
empire will set the path to be the cheapest path (in terms of
length) that currently exists. The unit(s) will move to the
destination sector, and then ask for more input.
.s1
For example,
.EX nav 18 -6,-2
.NF
<104.2:104.2: -6, -2> h
patrol boat #18 stopped at -6,-2
.FI
.s1
Note that if you are naving multiple ships, you may only specify a
destination sector on the command line if all the ships start in the
same sector.
.s1
The formula for the movement cost for 1 sector is:
.NF

	480 / (( speed + speed * (50+tech)/(200+tech) ) * Efficiency/100)

.FI
.s1
Moving a ship through a sector that has been mined
introduces a chance of mines/(mines + 50) of hitting a mine.
Minesweeps can remove up to five mines per pass through a
sector (indicated by the message \*QSweep...\*U).
Minesweeps also take 1/2 normal damage from mines.
.s1
Also, note that some things may affect you while you are moving. Forts
belonging to hostile countries will fire at you when you come within
range. Hostile land/sea/air units may fire at/bomb your ships, if they're
on interdiction missions (see info mission).  If your enemy has a
stack of missiles on interdiction mission, then they will
automatically fire one after another until all of your ships are sunk.
The chance of missiles and planes hitting your ships is determined by
the "worst" ship in your fleet (see \*Qbomb\*U for the chance of
hitting).  Any damage incurred by the fleet is divided evenly among
all the ships in the fleet which are in the same sector.
.s1
.L NOTE
.s1
While navigating, you cannot enter a sector that belongs to another
country unless they have FRIENDLY relations with you. This includes bridges, and harbors.

.s1
 is the number or name of the country to whom
you are offering the loan,
.s1
 is the size of the loan.
(NOTE: do not use a dollar sign),
.s1
 is the length of the loan in days,
.s1
 is the interest rate, (per ), on the loan.
.s1

terms of the loan not provided on the command line
and sends a telegram to  announcing the loan offer.
.s1
If the other country accepts the loan,
(using the \*Qconsider\*U command),
the money will be transferred from your account
and you will be notified that the loan duration has started.
.s1
Note that the dependence of rate on the duration makes a 30 day loan
at 10% a worse deal than a 60 day loan at 15%.

.s1
.in +4
 is the name or number of the country to whom
you wish to offer the treaty.
.s1
You will be asked to set both the conditions for yourself
and for the other country.
.s1

a telegram will be sent to the other country indicating the offer.
If the other country accepts the treaty,
(using the \*Qconsider\*U command),
you will be notified that it has gone into effect.

You use the \*Qorder\*U command to give sailing orders to ships.
At each update, ships sailing under orders \*Qautonavigate\*U toward a
specific destination sector.  Telegrams notify you of arrivals.
.s1
ONLY merchant ship may be given orders, but in order to move during the
update a ship must have at least one crew (which may be civilian or military,
but not an uncompensated worker).  Merchant ships are those that
have 0 for their firing range and gun limit values.  
.s1
Note that your ships sailing on orders will be interdicted just as if
you were navigating them by hand.
.s1
.EX order  c      Clear Orders
.s1
     Use the clear option to wipe out any orders the ship
currently has.  This will remove all starting and ending
points and clear all the cargo levels for the ship.
.s1
.EX order  s      Suspend Orders
.s1
     If you want to keep orders but don't want the ship
to move during the update use the suspend option. 
A quick look at 'sorder' 
will display the eta time as suspended.
As long as a ship is suspended it will be unable to move
during the update.  
.s1
.EX order  r      Resume Orders
     Resume will allow ships that have a suspended order to move
again. 
.s1
.EX order  d  [dest2|scuttle|-]   Declare Orders 
.s1
To declare an order you have 3 options.
.NF
     1) Order a ship to any sector on the map.  
	When it arrives it will clear its orders.

     2) Order a ship to any sector, load goods,
        move to a second sector and unload goods.
        Continue to loop between the 2 points.

     3) Order a ship to any sector on the map.
        When it arrives, it will scuttle itself if it is in a harbor that
          is at least 2% efficient.  This is useful for tradeships.

Example:  You have a cargo ship (#6) in your harbor at sector 6,0
You want to move good between that harbor and another harbor at
sector 14,0. 

 order 6 d 6,0 14,0

This reads:
 Cargo Ship #6, move to sector 6,0 load goods, sail to sector 14,0
 unload cargo then load again and sail back to 6,0.

Example: You have a tradeship (#666) at sea in sector -10,0 and you
want to move it to a friendly harbor at 20,4.

 order 666 d 20,4 -

The ship will now move to sector 20,4 with the most efficient path.

Example: You have a tradeship (#666) at sea in sector -10,0 and you
want to move it to a friendly harbor at 20,4, and then scuttle itself.

 order 666 d 20,4 scuttle

The ship will now move to sector 20,4 with the most efficient path,
and scuttle itself when done.

Note that only trade ships can be given auto-scuttle orders, and won't
scuttle themselves at sea.

Set cargo Levels. 
.NF 
Example: Cargo ship #109 is at your harbor in sector 10,0.
You have agreed to trade 200 lcm and 100 hcm to your friend and
he will give you 100 shells each update.  His harbor is at -10,2.
Using 'order declare' you set up your start point 10,0 and end point -10,2

order 109 l 1 start lcm   200
order 109 l 2 start hcm   100
order 109 l 1 end   shell 100  

When your finished the output would look like this. 

sorder 109
shp #   type           x,y     start   end     len  eta
  109   cargo ship 2  10,0      10,0   -10,2    11   1

AutoNav Features.
.s1 
Whenever a ship is autoloading cargo, it will always wait until it loads
to capacity.  If a ship does not load fully it will not move!!! 
Remember 'ships need food!!' unless the NOFOOD option is enabled.
Set one of your cargo holds to load food or your ship will starve at sea.
When unloading cargo, the ship will unload all goods
listed in the cargo holds ONLY!  It will not unload any extra good
manually placed on the ship.  
.s1
If you are dealing with civilians 1 will be left in either the
sector or the harbor depending if your loading or unloading.
In either case when you arrive at the other harbor all but 1 civ
will be dumped into the harbor.  Be careful if you set civilians
as one of your cargo levels. 
.s1 
If the FUEL option is enabled ships will try and fuel when they load
cargo in the starting or ending point and they currently have a fuel
level less then half of their max fuel level. 
Auto fueling is not foolproof.  If you declare a 
long path and the ship does not pass through any harbors it might
run out of fuel and mobility. Remember ships can only autofuel 
in harbors. 
.s1
You can set any commodity in the game to be loaded on the ship.
However if you tell a ship to load a commodity it can not hold it
will be ignored.  Example:  If you tell a battleship to load
Lcm, and of course it does not have that capability, see 'show ship 
capability' that level will be ignored at the update.
Planes and Units are not commodities so they can not be loaded this way. 
.s1 
At update time, the most direct path from the ship to destination
is calculated.  Each ship is then autonavigated along that path to
the best of its mobility.  The path is calculated from what the player
knows of the world (what you can see using the \*Qbmap\*U command).
Open sea, bridges, harbors, and unexplored regions of the world
are considered to be navigable.  Your friend's harbors and bridges
may be uses as long as the harbor >= 2% and the bridge >= 60%. 
Your ships will also try to avoid any mines you have declared on your
bmap.  'x' or 'X' characters.  Should your ship hit a mine the ship
will stop moving and its orders suspended.  You bmap will also be updated
with a 'x' marking the sector for you. 
.s1 
If a ship sails in range of enemy forts they will be fired upon.
Setting your ship to autonavigate into an area with good fort
cover could result in many ships getting sunk fast.
However you could put an invasion fleet off someone's coast in a hurry. 
.s1 
If the ship has a 'sweep' flag
ships will try and sweep any mines if any are present as they move.
.s1
Radar operates continuously as the ship moves along the path, constantly
adding sector information to the known world map.
.s1
The autonav code will try and use as much mobility as possible and this
is all done before mobility is gained from the update.
After an update has completed
your ship will have mobility so it can be moved by hand if needed.

It represents a complete mission for one or more transports and escorts
taking off from one place and returning to base at the end of the mission.
.s1
 represents a list of planes which can carry commodities.
Only planes which have a transport capacity, belong in a sector which is

be successfully selected for the mission. Only planes with the para ability
may be used for paratroop missions.
.s1
 represent a list of fighter planes which are capable of escorting
the transports all the way to the target.
To be selected, escorts must have fuel and mobility.
.s1
 represents an assembly point, where all of the planes in the
mission meet before proceeding on to the target sector.
The assembly point must be owned by you, and must not be more than
four sectors away from any of the planes selected for the mission.
.s1
Route is a normal empire path specification. You may also give a 
destination sector on the command line, or at any time while giving
the route, and empire will use the best path from the current sector
to the desired destination sector.
.s1
If the planes manage to fight through enemy air defenses and arrive
on-target, each transport in the mission will be shot at by any
guns present on the ground.
Surviving transports will drop the paratroops they carry, which will
attack any enemy military occupying the target sector.
.s1
See info \*QAttack\*U for the exact procedure. The sector being air-assaulted
will have exactly the same reaction to being conquered as if it were attacked
by land.

.NA pray "Interacting with the Deity"
.LV Basic
.s1
There is one country in the game that has no material possessions yet
owns everything...
That country is country #0 (often called \*QThe Deity\*U).
The power of this ethereal country is unbounded --
it can do anything from creating a civilian
(as was the case with the first civilian),
to literally moving mountains.
.s1
Despite this great power The Deity keeps his hands out of the game
and country #0 only gets involved when there is a problem with
the source code, or prohibited activity is suspected.
The most common form of prayer
is the telegram; if you should be in need of aid type:

.EX pray

When the program requests your message for The Deity,
state it simply:
.NF
Enter telegram for your Gracious Deity; end with ^D
<512> I can't do anything!!!!
<488> HELP!!
<481> .
.FI
If this doesn't get helpful results then you should send a
second prayer with more specific details. e.g.
.NF
<512> Every time I type any command which requires a BTU
<461> I get dumped out of the game.  Can you help me?
<413> .
.FI
.s1
This last message is sure to move the compassionate Deity to
provide help.
.s1
In general, when you encounter problems, be as specific about them
as possible. Include a transcript of the output of the problem,
if available. The more information you provide, the easier it is
for the deity to give you a quick & fair fix for the problem.

Produce predicts how much is going to be produced at the next update.
It also shows you how much could be produced if more materials were
available in the sector.

Note that due to random rounding factors in the update, prod is not
totally accurate -- it may be off by a little bit.

In the syntax of the produce command
 is the area on which you wish information,
(see \*Qinfo syntax\*U).
Produce reports on any sector that would produce goods,
sectors that don't produce anything
or are less than 60% efficient are ignored.
.s1
A typical usage might be:
.EX produce 0:9,0:9 ?type=m
which would list data for mines
in an area to the south-east of the capital.

.NA radar "Perform radar scan from ship or sector"
.LV Basic
.SY "radar [ | ]"
The radar command bears some resemblance
to modern high-resolution radar.
It has a circular range dependent upon its efficiency.
.s1
To run land radar type:
.EX radar 
where  must be the sector where the radar station resides,
or an area that contains one or more radar stations.
.s1
The program will respond with the station's efficiency and range
and then display the area.
.s1
What is displayed is dependent upon the range.
Sectors and ships within 1/3 of the range
are displayed with their sector or ship designations.
Sectors at greater distances are indicated by a '?'
if they are inhabited by another country.
.s1
A 100% radar station in a country with infinite technology
on a clear day has a range of 16.
The range is linearly related to efficiency;
thus a 50% radar station can see half as far
as a 100% radar station.
The range is related to technology level in the \*Qusual\*U way,
i.e., it varies linearly with \*Qtechnology factor\*U
as indicated in the nation report;
see \*Qinfo nation\*U and \*Qinfo technology\*U for details.
.s1
Satellites will appear on the map as a '$'.
.s1
WARNING!
Land radar cannot spot submarines.
.s1
FURTHER WARNING!
Even worse, should your cunning enemy move troops right to your
doorstep and leave the sector designated a wilderness it would
show up on your very efficient radar as '-'.
Thus you would never know he was there....
Well, almost never.

where  is the number of a unit or an army designation.
.s1
To run naval radar type:
.EX radar 
where  is the number of a ship or a fleet designation.
.s1
Sea radar is highly dependent upon what kind of ship you
have and what kind the opponent has.
(e.g., Battleships can see battleships far away
but fishing boats must be close together to see each other).
.s1
The maximum distance at which ship A can see ship B
is dependent on two factors:
the \*Qspying\*U ability of ship A,
and the \*Qvisibility\*U of ship B.
Battleships have sophisticated communications equipment
which give them a maximum spying range of 6 while fishing boats,
having little such equipment,
have a maximum range of 2.
This factor is shown in a table in \*Qinfo Ship-types\*U
under the heading \*Qspy\*U.
On the other hand, the ships vary in size and consequently,
vary in visibility.
Battleships, oil derricks, and carriers are the easiest to see;
next come cargo ships, heavy cruisers and tenders, and so on.
See \*Qinfo Ship-types\*U for a chart.
.s1
Ship A will see ship B if the distance between them is less than:
.NF + 0.3i
             spy factor of ship A * visibility of ship B
efficiency * ------------------------------------------- * technology factor
                               20

Note that, although subs can not be found via radar,
destroyers automatically use sonar so they can see subs.

Planes with the ASW ability will
perform a sonar search on each sector as they fly through it.
Each sub contact will be reported only once, giving the sector and number
of the sub, from the sector in which it
is first detected (which may not be the sector the sub is in, as plane
sonar has a range dependent on acc, and a chance of finding a sub of

.FI
.s1
Relations are: \*QAllied\*U, \*QFriendly\*U, \*QNeutral\*U,
\*QHostile\*U, \*QMobilizing\*U, \*QSitzkrieg\*U, and \*QAt
War\*U. Each has certain ramifications.
.s1
.L Allied
Your ally is someone you trust deeply, and are willing to make
sacrifices for.  If you are allied with someone, then your forts,
ships, planes, & artillery will support them in battle.  Also, they
can over-fly you, and you will not be told.  (I.e. an ally can map you
out easily).  When you use the "wall" command, it sends a flash
message to all of your allies (see info wall).  If the ALL_BLEED
option is in effect, then you will benefit from tech produced by your
allies.  Allied nations are assumed to have "friendly" trade relations.
.s1
.L Friendly
When you accept a country as a trustworthy trading partner, then you
establish friendly relations towards them.  This allows them to sail
ships into your harbours, load and unload goods, fuel, and have their
ships repaired there.  You are allowed to "tend" and "follow" friendly
ships.  You are allowed to cede sectors to a friendly
nation, and may send them "flash" messages (see info flash).  You will
be warned, however, if they overfly
your territory.  And if they do it enough times, your diplomatic
relations towards them will be automatically downgraded.  You may
"spy" on a friendly nation with no consequences.
.s1
.L Neutral
You start out neutral towards all countries.  It simply means that you
are ambivalent towards them.  If they overfly your territory, you will
be warned and your relations will automatically downgrade.  Caught
spies will be deported.
.s1
.L Hostile
If you are suspicious that a nation may be planning to attack you,
but you are not committed to an all out war against them, then you
should declare hostile relations towards them.  This will ensure that
your planes will intercept theirs if they
try to over-fly you, and your forts will fire on their ships when they
sail within range.    Also, your a-sat's and abm's will attempt
to intercept their satellites and missiles independent of the target
sector they have launched them at, and your ships with anti-missile
capability will attempt to intercept any incoming marine missiles
within range.  Caught spies will be shot.
.s1
.L War
If you are committed to expending major resources against a nation,
then you should declare war on them.  This will cause all of your
ships, artillery, planes and missiles which have been put on a mission
to react to enemy movement.
.s1
The following paragraphs apply only if the SLOW_WAR option is used.
.s1
.L Mobilizing
If you are Mobilizing, it means that you have declared war, and are getting
ready to attack. You cannot attack someone's land until you are actually
\*QAt War\*U. At the next update, you will automatically move to
\*QSitzkrieg\*U.  Your interdiction of the enemy will be the same as
if you were hostile towards them.
.s1
.L Sitzkrieg
Sitzkrieg is the same as \*QMobilizing\*U. You still are unable to attack
their land. At the next update, you will automatically move to \*QAt War\*.
.s1
When you are At War with someone, you may attack them willy-nilly.
.s1
Note that if the SNEAK_ATTACK option is enabled, you can make an attack
on someone you're not at war with (not shelling or anything else, just an
attack or assault). For this privilege, you are charged $5K. Once your
attack is over, whether successful or not, you automatically declare war
on them and must wait through the normal SLOW_WAR procedure to attack again.
(In this case, the $1K fee for declaring war is waived)
.s1
Also, there is an automatic progression. If someone you are allied with
attacks you, you become hostile towards them. If someone you are neutral
to over-flies or attacks you, you become hostile towards them. Neither of
these progressions can lead to war, however, they both stop at hostility.

The repay command is used to repay loans from other countries.
.s1
The  argument is the number of the loan you are repaying
and if not included on the command line
it will be solicited by the program.

You can repay all or part of the loan with this command;
however beware of letting the loan become overdue --
the lender may decide to force collection
(see \*Qinfo collect\*U).

.NA report "List all countries and their status"
.LV Basic
.SY "report "
The report command displays a list of nations in .  It shows
their status (in-flux, visitor, active, etc), and their estimated tech,
education, research and happiness levels.
.s1
If  is a country name or number, it will only display information
on that country; if  is * then information on all countries will
be listed.
.s1
An example of a report command for the country \*QFroom 93\*U would
look something like this:
.EX report *
.NF
Thu Sep 14 16:10:40 1995

 9     Lorphos          96 - 121   120 - 150     0 - 23     12 - 17   Active

This is how the ranges are determined.
(1) If your value of the statistic is 0, then n/a (not applicable)
    will be printed in that column.

(2) If the value for both countries is > 100, then shift them down so
    the lowest one is at 100.

(3) Each of the following tests is made in order.  As soon as one of them
    is true, then  that will be the range for that statistic:
      2.0 * yours < theirs
      1.5 * yours < theirs < 2.0 * yours
      1.2 * yours < theirs < 1.5 * yours
      1.1 * yours < theirs < 1.2 * yours
      yours / 1.1 < theirs < 1.1 * yours
      yours / 1.2 < theirs < yours / 1.1
      yours / 1.5 < theirs < yours / 1.2
      yours / 2.0 < theirs < yours / 1.5
                    theirs < yours / 2.0

(4) Once the range has been determined, it is shifted back up to where
    it should be.

(5) There is a "minimum range" for the different characteristics:
      tech: 20
      res:  10
      edu:   5
      hap:   5
    If the distance between the high and low end of the range is smaller
    than the "minimum range", then the range is expanded (equally in both
    directions but never crossing zero) to be equal to the minimum range.
    However, it will never be expanded beyond twice your value of that
    statistic.

.NA retreat "Set retreat conditions/paths for ships or fleets"
.LV Expert
.SY "retreat [ | ] [] []"
.SY "lretreat [ | ] [] []"
The retreat command allows you to examine or modify the retreat 
paths and conditions of your ships or units. The following description
is for ships. Land units are exactly the same, except of course that
some of the retreat conditions (being sonared, depth charged, etc) don't apply.
.s1
The  and  arguments are provided to specify which
ships to view or give orders for. If a fleet designation is given when
specifying orders, the orders apply to all ships within that fleet.
.s1
Retreat expects an argument.  To see every ship you own, give it
the argument '*', or type "retreat *".
.s1
The report format contains the following fields:
.s1
.in \w'shiptype\0\0'u
.L shp#
the ship number
.L shiptype
the type of ship; \*Qpatrol boat\*U, \*Qsubmarine\*U, etc,
.L x,y
the ship's current location (relative to your capital),
.L flt
the fleet designation letter (set by \*Qfleetadd\*U command),
.L path
the ship's current retreat path.
.L as_flt?
whether or not the ship's retreat path is a fleet retreat path
.L flags

.L Overview
.s1
A player may give retreat orders for a ship or a fleet. Retreat 
orders include a set of conditions that determine when the fleet/ship
will retreat, and a path that the fleet/ship will follow. When a condition
is met for a particular ship, the \*Qas flt?\*U field is checked. If it
is Yes, then every ship in that fleet with fleet retreat orders retreats
along the specified path. If it is no, then the retreat orders apply to 
that ship only, and only that ship retreats.
.s1
When a ship is added to a fleet, it is given the retreat orders of that
fleet, if any exist.
.s1
Retreat orders are wiped when a ship navigates.
.s1
Retreat conditions at present include:
.nf

		Condition	Meaning
		I		Retreat when the ship is injured,
				i.e. whenever the ship is damaged
				by fire, bombs, or torping.
		T		Retreat when a sub torpedos or tries
				to torpedo the ship.
		B		Retreat when a plane bombs or tries
				to bomb the ship.
		S		Retreat when the ship detects a sonar
				ping.
		D		Retreat when the ship is depth-charged.
		H		Retreat when helpless. A ship is helpless
				when it is fired upon, and no friendly
				ships/sectors (including the ship itself)
				are able to fire back at the aggressor.
                U               Retreat upon a failed boarding attempt.

You use the \*Qsail\*U command to give a sailing path to ships.
At each update, ships with a sailing path \*Qautonavigate\*U along
the path that was set for them.  Telegrams notify you of arrivals
or problems encountered while attempting to follow the path.
.s1
Radar operates continuously as the ship moves along the path, constantly
adding sector information to the known world map.
.s1
Ship movement is performed before mobility is increased.
This insures that after the update, ships with a sailing path will still
have some mobility so that you can always manually navigate
to some extent.

.NA satellite "Download data from a reconnaissance satellite"
.LV Expert
.SY "satellite  [ [?cond&cond&...]]"
The satellite command is how you get information from your satellites.
A satellite must be in orbit (launched)
before it will begin transmitting.
The type of information you get from a satellite
depends on what type of satellite it is.
.s1
An ordinary satellite will return data that looks remarkably like
\*Qradar\*U output.
If the satellite has \*Qimaging\*U capabilities
you will see the sector designations.
If not then you will see a '?' for inhabited sectors.
.s1
A satellite with imaging capabilities
will also show ships and land units.
.s1
Spy satellites provide much more information.
Their output is a table that looks remarkably like \*Qspy\*U output
followed by another table listing all the ships in the area with
their owner, ship type, and efficiency.
.s1
Spy satellites with \*Qimaging\*U capabilities can also see subs!
.s1
After launching, a satellite will take a while to come \*Qon line\*U.
During this period,
(shown by mobility being < 127),
you cannot use the satellite.
.s1
If a satellite has been damaged, then it will only transmit partial
data.  For example, a 75% satellite will only display three out of
every four sectors.  Note that it will always be the same 75% of
sectors which are displayed (i.e. it is not random), so you will gain
nothing by repeatedly downloading data from the satellite.
.s1
You may also filter the information you receive from the satellite
using conditionals.  Here are some examples to show you how
conditionals work.  In all of the following examples, we will assume
that we are using satellite #28.
.s1
To list all airports:
.EX "sat 28 se ?des=*"
To list all airports owned by country #7:
.EX "sat 28 se ?des=*&own=7"
To list all ships in 12,14:
.EX "sat 28 sh ?xloc=12&yloc=14"
To list all land units:
.Ex "sat 28 l"
To list all cavalry units:
.EX "sat 28 l ?type=cavalry".
.s1
For a complete list of conditionals you can use, see info Syntax.
Note that the large radar map is only drawn when the output is not filtered:

.SY "sharebmap   []"
This command will share all of the information on your bmap with the
country .  In order for it to work, they must be friendly
towards you and your bmaps must already overlap to some extent.  Note
that your 'working' bmaps are not compared for this, but rather your 'true' bmaps.  In particular, you can not fool the game into thinking
that your bmaps overlap through using the 'bdes' command.  See the
bottom of 'info bmap' for an explanation of the difference between
your 'working' and your 'true' bmap.
.s1
When sectors owned by you get transferred to your friend's bmap, they
will be replaced with the first letter of your country name
(capitalized), the only exception being harbors and bridges which will
always be transmitted.  Also, if you want to send them the location of
owned sectors having a certain designation you can specify that using
the optional  argument.  For example if your country name was
"TheScum" and you typed:
.EX "sharebmap Fodderland #1 j"
then all of your bmap would be added to Fodderland's bmap, with sectors
owned by you replaced with 'T', except for your '=', 'h', and 'j'
sectors which would be sent as is.
.s1
Note that the destination bmap will only be changed if in that
location there was a '?', a '.', a ' ', or the first letter
of your country name (capitalized).  Thus, the receiving country will
not loose any information in this exchange.
.s1
Note that the sharebmap command only changes your 'working' bmap and
so you can delete sharebmap information from your bmap by typing:

The shoot command allows you to shoot \*Qenemy\*U civilians
or recalcitrant uncompensated workers.
In order to be able to keep the populace under control
(i.e., not have them rebel),
you must have one military for every ten civilians.
Any land units in the sector count towards the mil necessary for control.
Also, security units in the sector will make shooting more efficient, 
.s1
Each civ or uw shot uses mobility (see \*Qinfo Mobility\*U for the
exact formula).

it will list each sector where your troops shoot down the poor
helpless people along with the number of people murdered.

If all the civilians in the sector are removed,
and it was a conquered sector,
it will become completely controlled by you,

of the firing squads,
resulting in more dead than you asked for. (They're enthusiastic)

.NA sonar "Use sonar to look for ships"
.LV Basic
.SY "sonar  "
The sonar command allows ships to look for submarines
and submarines to look for ships.
.s1
If the  argument is
specified then the sonar map will not be drawn.  This is useful if you
just need to see the list of ships you can detect.  Whether or not a
map is printed, the sonar information will be added to your bmap.
.s1
Only ships at sea may use sonar and sonar only detects ships
which are at sea.  Furthermore, there must be a straight line of water
between the detector and the detected (sonar doesn't work around corners).
.s1
In the current implementation, sonar works similar to 
lookout.  The major difference is that a submarines cannot use
lookout to sight ships.  Likewise, submarines cannot be sighted
by ships via lookout.
.s1
There are two aspects to sonar - passive and active sonar.
.s1
ACTIVE SONAR
.s1
This is the most visible form of sonar.  It is simply a
ship's ability to use sonar pings to detect other ships.
The range of a ship's active sonar is identical to the
range that it can sight ships via lookout.
(see \*Qinfo lookout\*U)
When you type "sonar 25", you are using active sonar.
.s1
PASSIVE SONAR
.s1
This is more subtle.  Passive sonar is a ship's ability
to hear sounds, mainly active sonar pings.  When a ship
pings you with active sonar, you can detect that ping.
If a ship with sonar gets pinged, that country receives
a telegram saying "Sonar ping from x,y detected by ship Z!"
In its current implementation, passive sonar is the ability
to detect a ping.
.s1
When a ship emits a ping, that ping has to travel out to a
target ship, reflect off of it, and then return to its source.
So, in order to detect a ship X sectors away, a sonar ping
must be able to travel 2X sectors - from the source to the
target, and back to the source.  So, if a ship can use active
sonar to detect ships X sectors away, passive sonar can detect
active sonars from 2X sectors away.  So the range at which you
can detect sonar pings is twice the range at which you can use
sonar.
.s1
The active and passive sonar modes means that you want to be
careful when you use sonar, because you will tell others where
you are long before you actually detect them.  This also gives
you some warning before you get your submarine attacked, as
enemy ships have to use sonar to find you.  The key to submarine
warfare is "run silent", meaning use your sonar only when you
have to.
.s1
On the other hand, destroyers are designed to hunt subs.  A
destroyer guarding a player's coast should use sonar often,
especially if it has other destroyers nearby to support him if
he gets in trouble.
.s1
For example:
.EX sonar 3
.NF
sb2 submarine 2 (#3) at 24,0 efficiency 76%, max range 2
Sonar detects TheBorg (#5) bb4 battleship 4 (#1) @ 23,-1
  .
 . B ?
. . 0 ?
 . . .
  . . .
.FI
.s1
Sonar-capable ships of tech 310 or better can also detect mines with
their sonar, although at only half their normal sonar range.  Mines
will show up on the sonar map as 'X' and this 'X' will be added to
your bmap.
.s1
In the case of using sonar to detect subs, detection = (sub visibility + ship
spy value).  If detection is less than 8, then the sonar will just
print you something like:
.NF
  Sonar detects sub #12
.FI
If detection is above 7, then you will be told the ship type, and if
it is above 9, you will also be told the owner of the sub.  Note that
type and owner will always be shown for Friendly subs.

The spy report will reveal, (in round figures), the numbers of troops,
civilians, guns, shells, iron, and planes and the sector designation and

Note that the number of BTU's consumed
is dependent upon the number of sectors into which you spy,
e.g., a 5x8 area costs one full BTU.

If you are spying on an unallied country your spy could be apprehended...
his/her chances are dependent upon the number
of patrolling military in the sector.
.s1
However, having a recon unit in the sector the spy is coming from
enhances your chances of succeeding even if the spy is caught.

.SY "supply "
The supply command causes a unit to draw enough supplies from its

Supply tells you which units have enough supplies.
.s1
A basic load of supplies for a unit consists of:
.nf
	1) enough food to eat for one update

	2) enough shells to fire once
		A unit uses shells equal to its ammo stat to fire once.
		Use the \*Qshow\*U command to find out how much ammo
		the unit uses per shot.

	3) petrol equal to its fuel use number, if the unit uses fuel
		(show land stats will show the fuel use number)
.fi

.s1
If the unit has enough of all these things, it is said to be 'in supply'.
A lack of any of these things is enough to make the unit 'out of supply'.
.s1
.L "When supplies are drawn & used"
.s1
A unit that fights may use a basic load of supplies
to attack with.  (depending on the intensity of combat. The more intense the
combat, the more chance the unit will use a basic load of supplies)
.s1
During the update, each unit will attempt to draw food supplies just before
starvation is calculated.
.s1
When a unit needs to draw supplies, such as when you use the supply command,
or the unit wishes to attack, or is attacked, etc, it must attempt to get
them from supply sources. Other things may use the same routines, such as
loyal sectors, which will draw food from supply sources when in danger of
starvation, and ships/forts/sectors, which will draw shells when they need
them to fire defensively or fire AA at planes.
.s1
.L "Supply Sources"
.s1
There are four sources of supply. In each case, the
unit must be within supply range of the source. Supply range is:
.s1
.ti 3
10 * ((tech+50)/(tech+200) sectors.
.s1
In addition there must be a valid supply path to the source. A supply path
is a path of sectors owned by the owner of the unit that leads to the 
supply source. (Note that the path may be of any length.. only the supply
source itself must be within supply range.. this is to make the coding
simpler, and may change in the future) The best path (in terms of mobility
use) will be used.
.s1
In each case, mobility is used to move the supplies.
.s1
The first source of supply checked is the sector the unit is in.
This is foraging, and uses some mobility from the unit itself.
.s1
If the unit's needs can't be satisfied by forging, it look for an owned
warehouse or headquarters that is at least 60% efficient. Drawing
from these sources uses mobility from
the warehouse or headquarters. (A headquarters will NOT supply a unit if it
has no distribution path)
.s1
If still in need, the unit will look for an owned supply ship (one that has
the supply ability) in an owned harbor.
The harbor must be at least 2%
efficient. This uses mobility from the harbor.
.s1
If it still can't find enough supplies, the unit will look for an owned
unit with the 'supply' ability. (see info show for information on how to
find out about abilities of units) In this case, the supply unit uses its
mobility to use the supplies. After it supplies the unit, the supply unit
will then itself try to re-supply, so that it is possible to form a chain
of supply units reaching back to a headquarters or supply ship.
.s1
If after all this the unit can't get enough, it is out of supplies.
.s1
Note that no supply source will give up enough food to make it starve. In
addition, no supply source will go below 1 of any commodity.
.s1
.EX supply *
War band #2 has supplies
.ti 3

.s1
OTHER USES OF SUPPLY
.s1
In general, when any land unit/ship/fort needs shells, it will attempt to
draw them before use, if it does not already have them.
.s1
Also, units/ships/sectors will use supply sources to get enough food during
the update so that they do not starve.

Each sub contact will be reported only once, giving the sector and number
of the sub, from the sector in which it
is first detected (which may not be the sector the sub is in, as plane
sonar has a range dependent on acc, and a chance of finding a sub of
((100-acc)-(4-sub visib)*10))+((100-effic)/5) percent.
The sub being sonared may detect the sonar ping. 
.s1
Planes with the sweep ability will
automatically attempt to sweep mines in sea or harbor sectors they overfly.
Their chance of sweeping is (100-acc), and they can only sweep 1 mine per
overflight of the sector.

Note that a plane must be at least 40% efficient before it can leave
the ground.

.NA telegram "Send \*Qdiplomatic\*U communique to another country"
.LV Basic
.SY "telegram  [] [[]]"
The telegram command allows non-treaty communication
to take place between representatives.  Currently you
are given only 1024 characters per telegram.

The  argument is either the number or name of
the recipient nation. You may specify as many recipients on the
command line as you wish.
Telegrams sent to country #0 appear as prayers,
(favors are best obtained in this manner.)
.s1
While entering your telegram the system tells you how many characters
you have left.  You end the telegram by typing ^D on a line by itself,
or by entering a line with a '.' on a line by itself. A line containing
only a '~' will abort the telegram.

.NA tend "Transfer commodities between ships"
.LV Basic
.SY "tend    "
The tend command allows transfer of commodities
from a particular (supply) ship to patrol boats,
submarines, battleships, etc. while at sea.
.s1
If you had cargo ship #16 which had food, and your fleet S needed food,
you could resupply the entire fleet with 20 units of food by typing
.EX tend 16 food 20 S
.s1
Requirements are that the tending ship must be in the same sector
as the tended ships, and it must be yours, or belong to a country that
considers you a friendly trading partner.
A positive  indicates the amount the tender will give away,
while a negative amount indicates the amount that the tender
will try to extract from each ship. (However, you cannot take goods
from a friendly ship by giving a negative amount)
.s1
Only land units with the "assault" capability may be tended between
ships.  If you wanted to tend land unit #23 from ship #8 to ship #17,
then you would type:
.EX tend 8 23 land 17
Besides the "assault" capability restriction, tending land units has
the same effect as though you were simply loading the unit onto a
ship.  In particular, you may tend land units to "friendly" ships in
the same sector.

In Empire, sectors may be given a territory id number.
This number may be used in conditional statements as in:

The program will then give you a census report for all the
sectors that have been assigned the territory number \*Q27\*U.
.s1
In this sense it is essentially an extended \*Qrealm\*U.
However, you are not limited to rectangular regions and you have 
99 values to choose from.
.s1
There are four independent territory fields.  If the optional field
argument is empty, field 0 is used.

The test command lets you check the effect of a proposed move.
This can be helpful when you're not sure whether you have enough
mobility to reach a certain location or you wish to compare two
possible routes for a move.
.s1
The test command has exactly the same arguments as the move command
and acts almost the same.
There are two important differences:
.in +0.3i
.s1
Nothing is actually moved and no mobility is used.
.s1
The move is tested for   irrespective of how much
 is actually in the sector.  This is useful for testing a sector
which will be used as a temporary stopover in a multi-step move to
make sure the stuff won't get stranded there.

The threshold command is used to specify the level
of a given commodity which is to be maintained
by the sector's distribution sector.
These levels are maintained by either importing or exporting
commodities.
This importation and exportation is done automatically during
an update.
Both imports and exports from distribution sectors cost only
one-half normal mobility.

between sessions.  If you do not specify the second argument ("on" or
"off"), then the server will just flip the switch from on to off or

.NA torpedo "Slip a torpedo to some poor sucker (from a sub or ship)"
.LV Basic
.SY "torpedo  "
The torpedo command is used to shoot other naval vessels
in a sneaky manner.
.s1
The  argument is the victim ship number and
the  argument is the number(s) of your submarine or other
ship(s) with torpedo ability.
The program will ask for these if not provided on the command line.
If using the multi-fire option, the program will prompt for targets for
EACH firing torpedo ship, if no target was given on the command line.
.s1
Your  must meet the following criteria:
.nf
.in +0.3i
1) It must have torpedo ability. (see info show)
2) It must have at least 1 gun (torpedo tube)
3) It must have at least 3 shells (3 shells = 1 torpedo)
4) It must be at least 60% efficient
5) It must have some mobility
.in -0.3i
.fi
Meeting all these criteria, your torpedo will be launched
toward the victim ship and a countdown of seconds
until the expected detonation will commence.
.s1
The range of a torpedo depends on the type of sub, and its tech
level. Currently the range formula looks like this:
.nf
	(frng) * (tech+50)/(tech+200)

	[Note: frng comes from show ship capability]
.fi
.s1
If the target is out of range, you will be told so,
(after your torp is in the water).
See \*Qinfo Hitchance\*U for the chance of a torpedo hitting its target.
.s1
If the target ship is not in a direct line of sight
but in range, the torpedo
will slam into land and you will be notified.  Note that the victim ship
will still see the torpedo being launched and can return a depth charge
attack (see below.)
.s1
A hit will be reported to you as \*QBOOM!\*U,
See \*Winfo Damage\*U for the damage that a torpedo does.
.s1
In order to simulate the \*Qreal-time\*U situation,
your mobility will be decremented by mobility equal to 1/2 the cost
the torpedo-ship would pay to move a sector for each torpedo fired;
if it goes to zero (or beyond) you will be forced to stick around.
If your torpedo scores a hit,
your victim will be informed of the fact and will be told
the number of the torpedo-ship, but not the country (so you can deny it).
.s1
The victim's only automatic protection against sub attacks is that
any ship of his/hers that is near you and has depth-charge ability
and has shells will drop them on you as depth charges.
Each depth charge does 10% to 40% damage to your sub, depending
on the armor of the sub, and the range of the destroyer.
.s1
The range a ship can depth charge at is the same as its gun range.
.s1
Against surface ships launching torpedo attacks, the victim gets to fire
all his ships & sectors within range at the attackers BEFORE the attackers
get to fire. Damage done by all defending ships is divided evenly over all
attacking ships.

.s1
The wall command allows instant communication between allied nations.
It may be called in two different ways.  You can either send your ally a one
line message as in:
.EX wall Hi there, I'm back from lunch
.s1
Or you can send a multi-line message:
.EX wall
.NF

.FI
Note that you can end a multi-line wall with either a '.' (period)
on a line all by itself, or by hitting ^D on a line by itself.
Note also that all messages are truncated to 60 characters long!

If you do not wish to receive any broadcast messages from your allies,
then you can temporarily turn the feature off by typing "toggle flash".

.NA wingadd "Designate members of a \*Qwing\*U"
.LV Expert
.SY "wingadd  "
The wingadd command is used to specify the wing groupings
of your planes.
.s1
.EX wingadd  
In the syntax  is the alphabetic character to be used as the
wing designation.
This character can be chosen from the set of
upper or lower case a-z and tilde (~).
The pseudo-wing specification tilde
specifies all planes not currently in any wing.
.s1
The specification of planes, ,
can have one of several syntaxes:
.NF
example     meaning
-------     -------
23          plane 23
2/14/23     planes 2, 14, and 23

~           all planes currently in the \*Qnull\*U wing
2,3         all planes in sector 2,3
-1:3,0:2    all planes in the square area bounded by -1,0 & 3,2
.FI
All wings, (with the exception of the `~' wing),
are limited to some maximum size
and you will be informed how many planes can be added
when this command is run.
.s1
Having planes organized into wings can be very helpful in
loading, moving, etc.,
in that fewer commands are required to perform these commands
on groups of planes if they can be specified by wing number.
.s1
Note that you can remove planes from a wing by adding them to
the `~' wing.  e.g.
.EX wingadd ~ A
This command would purge all planes from wing `A'.

The increase in efficiency depends on mobility used. It costs a 100%
efficient land unit 6 mobility to raise a sector 1% efficiency.  Less
efficient land units are charged proportionally higher amounts of
mobility.  For example, a 50% land unit would be charged 12 mobility
to raise the efficiency of a sector by 1%.

Any land units in the combat will fight as if they were simply mil,
i.e. they won't get any offensive of defensive multiplier, except for
"marine" units which get their full bonus.  Similarly, units
on land units don't have to take morale checks, as they are fighting as mil.
Mil on the victim unit will still die before units take casualties, however.

This info page describes 5 different commands: "attack", "assault",
"paradrop", "board" and "lboard".  These are the four commands that you
use to take something (either a ship, land unit or a sector) from the
enemy by force.

Note that much of the board information relates to the lboard information,
just apply it to a land unit instead of a ship.

.NF
A combat has 15 steps:
(1)  Ask the aggressor for the target sector/ship.
(2)  Ask the aggressor further details about the offensive force.
(3)  Estimate the odds and possibly ask the aggressor for confirmation.
(4)  Move reacting defensive units to the target sector.
(5)  Calculate defensive support.
(6)  Fight.
(7)  Spread the plague.
(8)  Take mobility and supply from land units.
(9)  Send reacting units home.
(10) If successful, the aggressor takes the target sector/ship.
(11) Remove mobility and efficiency from the target sector/ship.
(12) Remove mobility from the aggressor's sectors/ship.
(13) Possibly ask the aggressor for mil and units to move into the target.
(14) Possibly interdict the aggressor's mil and units as they move.
(15) Charge the aggressor BTU's.
.FI
.s1
.L "(1)  Ask the aggressor for the target sector/ship."
.NF
Sea, sanctuary, and wasteland are illegal targets.
You may not assault a mountain.
You may not paradrop into a mountain, capital, city, or fortress.
You may only board a ship from the sector the ship is in, you may
not board a ship which is faster than your ship, and you may not board
a submarine at sea.
You may only board a land unit from the sector the land unit is in.
.FI
.s1
The "assault" command is the only command which will let you attack
your own sector (you can use this to get mil & assault units on
shore).  You should not "attack" unowned land (see info explore).
.s1
If the SLOW_WAR option is enabled, you will not be able to attack
a sector owned by a country you are not AT_WAR with, unless you
are the old owner of the sector.
.s1
If the SNEAK_ATTACK option is also enabled, you can attack ONE sector
owned by a country you are not AT_WAR with, paying $5K for the
privilege. Once the sneak attack is done, you will automatically
declare war against the enemy, and go through the normal SLOW_WAR
sequence before you can attack again (see info relations).
.s1
.L "(2)  Ask the aggressor further details about the offensive force."
.s1
When you board, you are asked for a ship or sector to board from.
If you are attacking or assaulting, then you have the option to
specify whether you want your forts/ships/plane/units to support your
attack.  If no support is specified, then it is assumed that
you want support from all sources.
.s1
If you are not paradropping, then you will be asked for mil and units
you would like to attack with.
You must always leave at least 1 mil in
the sector or ship you are attacking from, so you may never attack
with all of your mil out of a sector or ship.  
The following limitations apply to the aggressor's mil:
.NF
Attack:  You are limited by the mobility of the attacking sector
         according to the mob-cost to move the mil into the target sector.
Assault: If the target sector contains mil, then you may only attack with
         1/10th of your mil on board, unless your ship has "semi-land"
         capability in which case it is 1/4th, -or- if your ship has 
         "land" capability in which case there is no limitation.
Board:   When boarding from a sector, the sector must have mob.  When
         boarding from either a ship or a sector, the number of mil
         you may board with is limited to the maximum number of mil that the
         target ship can hold.  Note that you can board land units
         from a sector only.

The following restrictions apply to the aggressor's land units:
A land unit must have mobility and be in supply (see info supply) in
order to be able to enter the combat.  Land units with "security",
"supply" or "flak" capability may not attack.  Also, you may not
attack with artillery units (i.e. if frg > 0).  Only land units with "assault"
capability may assault or board.
Attack:  The land unit must have at least as much mobility that it
         would cost for it to march into the sector.
Board:   You may only board with as many land units as the target ship
         can hold.  You cannot board a land unit with other land units.
.FI
.s1
When asked whether you'd like to include a certain land unit in the
combat, you will be given a prompt ending in [ynYNq?].  At this
prompt, you can type:
.NF
y - yes this unit
n - no this unit
Y - yes all units in this army
N - no all units in this army
q - quit attack
? - print this help message
.FI
.s1
.L "(3)  Estimate the odds and possibly ask the aggressor for confirmation."
.NF
The offense strength of your land units is mil * off where "mil" is the
number of mil in the unit, and "off" is the offense multiplier of the
unit (see show land stats), with the following exceptions:
Assault: If the unit doesn't have "marine" capability, then its
         offense strength is cut in half.
Board:   If the unit doesn't have "marine" capability, then its
         offense strength is equal to half of the number of mil in the unit.
.FI
.s1
The total offense strength is the number of mil plus the offense
strength of all offensive units.  This number is then multiplied by
the offense value of the sector the mil and units are attacking from
(see show sector stats).  Ships have an offense value of 1.
.s1
The defense strength of a land unit is the total number of mil in the
unit times its defense multiplier (see show land stats).  The only
exception to this is non-marine land units on ships which have a
strength equal to the total number of mil in them.  The defense
strength of units out of supply is cut in half.  The defense strength
of fortified units is multiplied by (127 + fortification) / 127.
.s1
The total defense strength is the number of mil plus the defense
strength of all defensive units.  This number is then multiplied by
the defense value of the sector the mil and units are in (see show
sector stats).  Ships have a defense value of 1 + def/100 (see show
ship stats).  You can use the "strength" command to see the defense
strength of your sectors.
.s1
Now, When your scouts estimate the defense strength, they only count
land units and mil that they see.  If your scouts didn't notice the
efficiency of the defending units, then they assume that they are at
100% efficiency.  Your scouts also assume that none of the enemy units
are fortified.  Once your scouts have come up with an "estimated
defense strength", then that number is compared with your offense
strength.  The
output so far might look like this:
.EX attack -14,2
.NF
-14,2 is a 100% 5 harbor with approximately 0 military.
Number of mil from headquarters at -15,3 (max 108) : 10
cavalry #7 has a base attack value of 44
attack with cavalry #7 in -15,3 (~ 100%) [ynYNq?] y
cavalry #24 has a base attack value of 44

             Initial attack strength:      108
Scouts report defending unit: inf1  infantry 1 #22 (efficiency 71, tech 169)
Scouts report defending unit: inf2  infantry 2 #41 (efficiency 94, tech 169)
Scouts report defending unit: inf2  infantry 2 #42 (efficiency 94, tech 173)
Scouts report defending unit: inf2  infantry 2 #43 (efficiency 65, tech 139)
          Estimated defense strength:     1118
                      Estimated odds:        8%

.FI
.s1
Note that your estimated odds are calculated before any enemy units
have reacted, and before support multipliers are calculated, so they
will not be particularly accurate.
.s1
.L "(4)  Move reacting defensive units to the target sector."
.s1
If the target is not a mountain, then defensive units in nearby
sectors may react.  Defensive units will keep reacting until the
defense strength is 1.2 times the offense strength.  The following
restrictions apply to reacting land units:
.NF
- The efficiency of the unit must be higher than it's retreat percentage.
- The unit must be in supply.
- The unit must have enough mobility to get to the target.
- The unit must be in range.
.FI
If the unit is in a 60% efficient headquarters, then 1 is added to its
reaction radius.  If it is on "reserve" mission, then 2 is added to
the radius.  Note that you can limit the reaction radius of your land
units using the "lrange" command.
.s1
.L "(5)  Calculate support."
.s1
For attack and assault, both offensive and defensive support is
calculated.  For paradrop, only defensive support is calculated, and
for board and lboard there is no support (however, defending ships within range
will fire on the boarding ship or sector before the fight if boarding
a ship).
.s1
The aggressor's support is calculated based on what the aggressor
asked for.  Defensive support is only called in to the extent that it
would be useful.  If the aggressor outnumbers the defender 10-to-1,
then the defender will not have any support.  Otherwise, the defender
will keep calling in support until its strength is at least 1.2 times
the offense strength.
.s1
Fort, ship, and unit support is simply those forts, ships, and units
in range that can fire (see info fire).  Note that ships and units on
missions will not fire support.  Plane support comes from
those planes on "support" mission.  The support multiplier is
.NF
1.0 + fortdamage/100 + shipdamage/100 + planedamage/100 + unitdamage/100.
.FI
.s1
Ships/forts/units belonging to allies of the combatants will support,
if they are at war with the other combatant. (For example, if A is allied
with B, and at war with C, and A attacks C, things belonging to B will
support the attack if able. The same is true for defense. If C attacks
A, the B stuff will help defend A)
.s1
After these four supports are calculated, then land mine support is
added to the defense support.  Defending land mines add (number of mines) *
0.02 to a maximum of 0.40.  If there are attacking engineers present,
this number is cut in half.
.s1
.L "(6)  Fight."
.s1
Total offense and defense strength are multiplied by their support
multipliers to obtain the final combat strengths.  From this, odds are
calculated.  Then in each "round", a chance according to the combat
odds determines whether an aggressor or defender troop is lost.  Troops
killed in combat are first taken from the mil (from the sector
containing the most mil), and then from the units (from the unit
containing the most mil).  Combat odds are recalculated and the
process continues until there is a victor.  Each time there is a
casualty, a character is printed:
.NF
! means a defending soldier bit it
@ means one of your soldiers went doan
.FI
.s1
If the effiency of a land unit is less than its retreat percentage when
it gets hit, then it will need to make a morale check.
The chance of failing a morale check is (retreat
percentage - efficiency).  If the unit has nowhere to retreat to, then
it takes "extra losses" which amounts to an extra 10% docked from its
efficiency.  Otherwise, the land unit retreats to the adjacent sector
containing the maximum number of civs.  Units will never retreat into
mountains.
.s1
Also note that once all of the military on a land unit are killed, the
land unit stops defending.  What this means is that a land unit can
become "trapped" in an sector if an enemy takes it over after killing
all the military on a land unit while the land unit may not be destroyed.
.s1
When planning an attack remember that overwhelming forces greatly increases
your odds; i.e., attacking 10 men with 40 will result in your losing
fewer troops than if you had attacked with 20.
.s1
.L "(7)  Spread the plague."
.s1
If any combatant in a battle is infected with the plague, all potential
comnbatants in the battle are infected as well (if they do not already
have some level of plague already.)
.s1
.L "(8)  Take mobility and supply from land units."
.s1
The "aggresor loss factor" is equal to the number of aggressor
casualties divided by the total number of aggressor troops that went into
the conflict.  Similarly, the "defender loss factor" is calculated.
Then each land unit loses mobility equal to 10 * (loss factor).
Defensive land units on reserve mission only lose half of that.  Also
there is a chance equal to the loss factor that the land unit will use
up some of its supply (see info supply).
.s1
.L "(9)  Send reacting units home."
.s1
If the defending land unit did not retreat, then send it back to where
it came from at no mobility charge.
.s1
.L "(10) If successful, the aggressor takes the target sector/ship."
.s1
Either 1 aggressor mil (first choice) or one land unit (second choice)
is automatically moved into the conquered ship or sector to occupy it.
Since this mil or unit is effectively "chasing out" the remnants of
the defending forces, the defender will not interdict it (because he
won't want to damage his forces with "friendly fire").
.NF
This is what happens to the sector when you take it:
- All delivery and distribution information is wiped.
- The production in the sector is stopped (see info stop).
- Planes in the sector owned by the player you just took the sector from
  lose 30 plus random(100) efficiency and go to 0 mob. If the new efficiency
  is less than 10%, the plane is blown up.
- Units in the sector owned by the player you just took the sector from
  lose 30 plus random(100) efficiency and go to 0 mob. If the new efficiency
  is less than 10%, the unit is blown up.
- The avail is set to 0.
- New che are created (see info Guerrilla).
- Set the loyalty of the sector to 50 (see info Loyalty).
- Reduce the mobility to 0.
- The civs in the sector become "conquered populace" (see info Occupation).

When you take a ship:
- Mission, retreat info and fleet info is wiped.
- Planes and land units on the ship are reduced to 10%.

When you take a land unit:
- Mission, retreat info and army info is wiped.
- Planes and land units on the unit are reduced to 10%.

When you take someone's capital, the defender loses half of their
money or $3000 whichever is greater.  If the defender wasn't broke to
begin with, then the aggressor gets half of their money times (1/5 +
4/5 * efficiency of the sector).
.FI
.s1
.L "(11) Remove mobility and efficiency from the target sector/ship."
.s1
The efficiency of the target sector or ship is damaged by a percentage
equal to the total number of casualties divided by ten.
.s1
If the target is a sector, then it will lose an amount of mobility
equal to the maximum of 20 and a percentage of the mobility equal to
the number of defender mil casualties divided by the total number of
mil that were originally in that sector.  So if for example, your
casualty fraction was 70/100, and your sector started with 50 mobility,
then you would lose max(20, 50*70/100) = max(20, 35) = 20 mobility.
.s1
.L "(12) Remove mobility from the aggressor's sectors and ships."
.s1
The pre-combat mobility costs are:
.NF
Attack:  Remove mobility equal to the mob cost to move the mil into the
         target sector.
Board:   If boarding from a ship, the cost is the half of the speed of the
         defending ship times the efficiency of the defending ship.
         If boarding from a sector, the cost is the number of boarding
         mil divided by 5. This applies for boarding of ships and land units.
.FI
.s1
Only sectors are charged an additional post-combat mobility cost.
In this case, the amount of mobility the sector loses is calculated
using the same formula as is used for the defending sector's mobility cost.
.s1
.L "(13) Possibly ask the aggressor for mil and units to move into the target."
.s1
If the combat was an assault, paradrop, board or lboard, then all victorious
mil and units are automatically moved into the target.  The mil are
moved in with no mobility charge.  If the combat is assault, then
the mil will take an amount of food with them proportional to the
number of people leaving the ship.  The mobility cost to land units is
as follows:
.NF
Assault: If the land units are attacking from a ship with "land" capability,
         then land units are charged (update mob) mobility, except for
         "marine" units which are only charged half of that.  For all
         other kinds of ships, land units go to -(update mob), except for
         "marine" units which go to zero.  Here, (update mob) refers to
         the amount of mobility that units gain at the update.
Board:   Marine units are charged 10 mobility and other land units are
         charged 40.     
.FI
.s1
In the case of attack, the aggressor is asked what they'd
like to move in as follows:  First, the aggressor is asked how many mil
they would like to move in from each attacking sector.  This number is
limited by the amount of mobility left in the attacking sector.  Then
the aggressor is asked which land units they'd like to move into the
sector with the same [ynYNq?] prompt as above, the only difference
being that 'q' now means "don't move anything in".  The mobility costs
here are the same as for "move" and "march".
.s1
.L "(14) Possibly interdict the aggressor's mil and units as they move."
.s1
Post-attack interdiction only occurrs in the "attack" command (and not
in "assault", "paradrop", "board" or "lboard").
When you move your mil into the target sector after an attack, you
will risk the same chances of interdiction (number of mil / 200) and
stepping on land mines (see "info lmine") as
if you were moving them using the "move" command.  
.s1
Similarly, once you have specified which land units you'd like to move
into the conquered sector, then all of your units will move in at
once, and they will be interdicted in the same way as though they were
being moved using the "march" command, including the danger of
stepping on land mines.  Note that there is no
post-attack interdiction and no danger of stepping on land mines if the
INTERDICT_ATT option is disabled (see version).
.s1
.L "(15) Charge the aggressor BTU's."
.s1
The BTU cost is equal to 0.5 + (the total number of casualties) * 0.015.

  For years now people have been setting up large groups of fishing
boats to feed their island.  These groups get very large and are
difficult to keep track of.

  This is an example of how to set up a fleet of fishing boats
so they will take their food produced each update and drop it off
at the harbor of your choice.

  See 'info order' for a complete description and example of
syntax for the 'order' command.

You have ships  0,12,88 in the harbor 15,1
Sector 16,0 has a very good fert of 93 so you want to use that
as your fishing grounds.

1) move your ships to sector 16,0
"nav 0/12/88 16,0"

2a) set up autonav using the 'order' command.
    "order 0 des 15,1 16,0"
    This will establish a circular trade route.

2b) set up food levels for the ship
    "order 0 level 1 start food 30"
    "order 0 level 1 end   food 30"

    You can also use a global '*' or a fleet letter here.
    "order * level 1 start food 30"
    "order * level 1 end   food 30"
   
    "order F level 1 start food 30"
    "order F level 1 end   food 30"

    NOTE: You should set BOTH start and end fields to insure
          autofeed will work correctly and set them at the 
          same levels!

    NOTE: if you are using autonav with normal cargo ships.
    Fishing boats are a special case to the autonav code.
    This setup will only work correctly with fishing boats.
    If you want to use autonav with cargo ships please use 
    the examples found in the 'order' command.

repeat 2a,2b for other ships in the area.

During the update your fishing boats will now move to the harbor at
15,1 unload food until it reaches 30, then move back to 15,1 and STOP.
If you're using fishing boats that require fuel, i.e. fb2
when the ship enters the harbor, and the fuel level is at 0, the
autonav code will automaticly refuel the ship for you.
So unless the ship gets sunk, or something happens to it, like the
civs starve on board if you don't leave enough food on it,
the ships will continue to feed your country and you won't even need
to think about them.

The Max limit that autonav will stockpile is 99999 units.
So if your sector get overcrowded the ship will sit in the harbor
until it can unload all of its food.

.NA Autonav "Giving ships automatic sailing orders"
.LV Expert
In a very short while after acquiring ships the effort of moving ships after
every update gets very boring.  And the more ships you have, the more work
it is.  Hence the concept of autonavigation.  Like any self-respecting
dictator, you don't personally drive your ships around (except when you want
to), instead you command you ship captains to take their vessels to a
specified destination.  This is done via the \*Qorder\*U command.
.s1
Each ship can be ordered to proceed to a destination.  During each update,
the ship will try and use ALL the mobility it has and use the shortest
possible path.  It will also avoid any known mines (sectors marked
with an 'X' or 'x' on your bmap).  Note that this movement is all 
done before mobility is accumulated, so that after the update is
complete the ship will have a full updates worth of mobility
in case you need to move it by hand.  Should a ship be fired upon
by forts or strike a mine they will stop moving!  This will prevent
your ship from foolishly getting sunk in enemy waters.  The
\*Qorder\*U command covers many special cases.

.s1
The autonavigation capability is dependent upon the per country map database
accessed via the \*Qbmap\*U command.  If you order a vessel to a destination
that causes it to cross a previously unexplored area, the ship will attempt
to cross that area as if it were water.  One of the features of the bmap
functionality is that when a ship is navigated, it automatically uses its
radar to see the local sectors (much like real life).  This sector information
is added to the per country map database.  Thus upon running into a previously
unknown obstruction, that information is added to the map database and on the
next update, a new path to the destination will be calculated which avoids
the obstruction.  This process applied iteratively means that a ships will
eventually find its way around any obstruction, provided that a path exists.
In reality, this is a limit to this process.  In order to limit the processing
that is done to find a path to the destination, the internal path string is
limited to 28 characters.
.s1
The other capability of the autonav function is autotrading.  By specifying
two destinations and two commodities, the ship will move back and forth between
the two destination loading and unloading the appropriate commodities.
Specific examples can be found in the \*Qorder\*U info file.
.s1
The same rules for navigating, loading, and unloading apply for
Autonavigation as they do when you do these things by hand, namely
that you may only use harbours owned by nations which consider you to
be a friendly trading partner (see info relations).

.s1
Normally bridges can only be built from bridge-heads. (See info

bridges can be built from any sector
that has enough hcm (heavy construction materials) and
workforce (see \*Qinfo show\*U and the \*Qshow\*U command),
providing you have enough money, and your technology level is high enough.
.s1
Bridges can only be built over water sectors.
.s1
If the EASY_BRIDGES option is in use,
you do not need to use bridgehead sectors (although the sector you
build from must still be at least 60% efficient), and
the sector the bridge span is to be built in must be adjacent to
at least 1 non-sea, non-bridge span sector. Note that you do not have to
OWN the sector is will be adjacent to, it just has to exist. This means that
you can build, for example, a 2 sector bridge out to an unowned island.
.s1
To find out the required amounts of materials, workforce, and money
use the show command.
.s1
Bridge spans cannot be re-designated.
A bridge span will collapse when it is below 20% in efficiency,
so shelling will destroy one, as will nuclear weapons and bombing.

.NA BTU "How BTUs are generated"
.LV Expert
.s1
It takes time for decisions to be made by top level officials, and it
takes time for their orders to reach those who execute them.
The potential of your government to process new information is
measured in Bureaucratic Time Units (BTU).
.s1
BTUs are generated in real-time based on the number of civilians that
are in your capital.  Every time you log out and in again, the server
calculates how long you've been away, and based on that time awards
you a certain number of BTUs.
.s1
Here is the procedure for determining how many BTUs you get:
.nf
If the game is a blitz, then as soon as your BTUs go below zero, then
they are automatically set back to 512.

(1) Count the number of civs generating BTUs.
  civs = maximum(999, number of civs in your capital sector)
  Note that if you don't have a capital, then you will get _no_ BTUs.

(2) Find out how many civs are required to make one BTU in one time unit.
The "version" command will tell you how many civilians are required to
produce one BTU in one time unit.

(3) Calculate how many BTUs your cap produces in one time unit.
Divide the number of civs generating BTUs (step 1) by the number of
civs required to produce one BTU in one time unit (step 2).  If your
capital is in a mountain or has zero efficiency, then multiply by
1/200.  Otherwise, multiply by (sector efficiency) / 100.  Note that
0% capitals and mountains generate BTUs as if they were 0.5% capitals.

(4) Calculate how many time units have passed.
The number of "Time units" (TU) since your last login is:
  TU = (number of seconds since last login) / (number of seconds per ETU).
The "version" command will tell you how many seconds are in an
"Empire time unit" (ETU).  If more than 336 time units have passed
since your last login, then set TU = 336.

(5) Calculate how many BTUs you get.
Multiply the number of BTUs your cap produces in one TU (step 3) by
the number of TUs which have passed (step 4).  This is how many BTUs
you get.  Note that there is a limit to how many BTUs you can have at
any given time.  This number is usually 512 but can be changed by the deity.

EXAMPLE: say you had a 100% capital containing 500 civs.
Suppose that version said:

It takes 25.00 civilians to produce a BTU in one time unit

Then first you would divide 500 by 25 to get 20.  Now since your cap
is 100% efficient, you would multiply 20 by (100/100) and so the civs
in your cap would produce 20 BTUs per time unit.  Now suppose that
version said:

An Empire time unit is 1440 seconds long.

and suppose that 1 day had passed since the last time you logged on.
Then that means that the number of time units which have passed is:
  TU = (number of second in a day) / (number of seconds per etu)
     = (24 * 60 * 60) / (1440)
     = (1440 * 60) / (1440)
     = 60
(Note that another way to find out how many time units there are between
updates is to find out how many ETU's there are per update.)
  Lastly, we multiply 20 by 60 to get 1200 BTUs.  But since the
maximum is 512, we would have 512 BTUs.  Note that if your capital had
been in a mountain sector, then you would have only gotten 6 BTUs in
24 hours.

Taxation of the civilian populace is one of the main providers of income
to an Empire nation (gold bars in banks, trade ships, and taxes from
uws being the only other sources of income in the game).
Also, only friendly civilians can be enlisted into the army, navy and
air force.
.s1
The loyalty of a given sector,
also known as the willingness of the civilian population to work,
is initially 100% -- that is, all of the people are working.
In the event that the sector is captured, starves,
or falls victim to revolutionary subversion,
the work of the sector will decrease.
This will be shown by the work % decreasing.
.s1
If people starve in a sector, the amount of work they do drops to 0
(because they are too weak to work).
.s1
If a sector is a conquered sector,
a star \*Q*\*U will be shown in the appropriate column
on the census report.
Friendly sectors allow enlistment of military,
as well as the ability to move the civilians freely about.
Occupied civilians will not move,
and friendly civilians cannot enter these sectors.
In addition, occupied civilians will not serve in the armed forces.
.s1
If the thought of not being able
to move conquered populace bothers you,
then you have the option of converting these conquered people
into uncompensated workers,
involving the expenditure of BTU's and money
(for the paperwork).
If all the conquered people in one sector are converted to uw's,
then the sector is then marked as yours.
.s1
If the people in a sector are unhappy
(due to starvation, subversion, or lack of happiness)
they can go on strike and cease working.
You can get them back to work by heavy-handed military control
(placing one military for each 20 striking civilians).
.s1
Finally, your populace requires happiness to keep their enthusiasm
for work going.  As technology and education increase,
your work force expects to share in the increased levels
by getting more consumer items (VCR's, BMW's, etc)
represented by happy strollers.
If you don't have at least one happiness point
per two units of education,
and a point for each forty units of tech,
your people will not be happy.

.NA Damage "How much damage stuff does"
.LV Expert
.nf
It is possible to be damaged by shells, bombs, land mines, sea mines,
and nuclear blasts.  This info page shows you how much damage each of
these things does.  In the following formulas, random(x) means a
random number from 1 to x.  Once the damage has been calculated, then
it is applied.  Damage applies to different kinds of things in
different ways (see below).


1. Calculating the damage

Shelling
You can be shelled by a fort, artillery unit, ship, depth-charge, or torpedo:
       fort damage = guns * eff * (random(30) + 20) / 7
       unit damage = guns * eff * (5 + random(6))
       ship damage = guns * eff * (10 + random(6))
      depth damage =    2 * eff * (10 + random(6))
       torp damage = 40 + random(40) + random(40)
Note that for forts, a maximum of 7 guns may be fired.

Bombs
A plane drops a number of bombs equal to the "load" the plane can carry.
Each bomb does the following damage:
     blam: 1 + random(6)
     Blam: 5 + random(6)
     BLAM: 8 + random(6)
When pinbombing a ship, plane, or land unit, damage is doubled.
Whether you get a blam, Blam, or a BLAM depends on the accuracy of the
plane and the difficulty of the target (see info bomb).

Land mines
Land mines damage commodities by random(20) and land units by 10 + random(10).
If the land unit is an engineer, then the damags is cut in half.

Sea mines
Sea mines damage ships 22 + random(20).  If the ship can sweep, then
the damage is cut in half.

Nuclear Detonation
Damage from nuclear detonation uses the following formula.  From
"show nuke stats", you see that each nuke has a certain blast radius
and %damage.  If you are groundbursting, then multiply the radius by
2/3.  If you are airbursting, then multiply the radius by 3/2.  Now
based on the distance from gound zero, the nuke does the following
amount of damage:

Groundburst: dam / (dist + 1)
   Airburst: 0.75 * dam - 20 * dist

For the small, medium, and large nukes currently in the game
(damage 80, 90, 101 and radius 1, 2, 3) the following damage is obtained:

         Groundburst          Airburst
         0       1            0       1       2       3
small   80                   60      40
med     90      45           68      48      28
large    /      50           76      56      36      16


2. Applying the damage

Once you know how much damage the bombs or whatever have done, then
you apply the damage to what was hit.  In the calculations below,
%damage will never be larger than 100%.  If it is, then we just say
that the %damage was 100%.  Once we have the %damage, then we apply it
as follows:

new efficiency = (old efficiency) * (1 - %damage / 100)

For example a 50% ship hit for 10% damage would go down to 45%.

The following formulas show you how to get %damage from damage.  Note
that these formulas are used in all cases _except_ nuclear damage.  In
the case of nuclear damage, %damage is always equal to damage (except
for planes hardened in silos which subtract their "hardened" value
directly from the damage).

Ship
%damage = damage / (1 + def / 100)

Land unit
%damage = damage * (vul / 100) * (127 / fortification + 127)

Plane
%damage = damage

Sector
sectdamage = damage / ((sectdef - 2) * eff + 2)
%damage = (100 * sectdamage / (sectdamage + 100))
commodities take %damage (bars take no damage and people take 0.4 * %damage)
land units take 0.3 * %damage
planes take no damage

Commodity
%damage = (100 * damage / (damage + 50))
bars take no damage
civs, mil, and uws take 0.4 * %damage

.LV Expert
.s1
Education is important for both technology and research production.
Your country will not be able to produce technology or research unless
your civilians have an education of at least 5.  (See "info Products"
for more details).
.s1
The \*Qnation\*U command will display, among other things,
your current education level.
.s1
.nf
This is how your new education level is determined every update:

(1) Graduates are produced in schools
See "info " or the "production" command to find out how many
Graduates you are going to produce.  Your update telegram will tell
you the class of graduates produced in your various schools in a line
like this:
  a class of graduates (135.00) produced in 3,1

(2) Calculate your education production efficiency
The higher your population, the lower your education p.e., as it takes
more graduates to maintain the same overall level of education.  Note that
with low population you education p.e. can be greater than 1.
The version output will contain a line like this:
  Education p.e. requires 1 class of graduates per 10000 civ.

Your education p.e. is now calculated as follows:
education p.e. = "civ. per graduate" /
		 "total pre-update civilian population"

number of graduates produced = class of graduates * education p.e

For example, lets say you have a pre-update civilian population of
40,000 and have produced a class of 260 graduates.  Your education p.e.
would be 10000 / 40000 = .25 and your number of graduates would be
260 * .25 = 65

 (3) Calculate edu delta from the number of graduates
"edu log base" is always 4.0 and "easy edu" is always 5.0.
To find out what your edu delta for the update will be, subtract "easy
edu" from the number of graduates you are producing and call
this number "over easy".  Now divide "over easy" by the log of ("over
easy" + "edu log base") base "edu log base", and then add "easy edu" back.
Simple eh?  ;-)

OK, here's an example:
Say you are producing 65 graduates.  Then your "over easy" would be 65
- 5.0 = 60.  Now the log of (60 + 4.0) base 4.0 is 3 (since 4 to the
power 3 is 64), so our edu delta will be 60/3 + 5 = 25.

(4) Calculate your new education as a weighted average
The version output will contain a line like this:
  Education is averaged over 192 time units
And the number of etus per update is printed in the version output as:
  An update consists of 60 empire time units.

Your new education is now calculated as follows:
"new edu" = ("old edu" * "average etus" + "edu delta" * "etus per update") /
            ("average etus" + "etus per update")

So if, for example, your old education level was 40 and your "edu
delta" was 25, then your new edu would be:
"new edu" = (40 * 192 + 25 * 60) / (192 + 60)
          = 36.43

.NA Fallout "The long lasting effects of nuclear war"
.LV Expert
This page describes fallout, and some of its effects.
.nf

Fallout is the result of nuclear bombs going off.  It is basically
just radioactive particles that float around in the air.

After nuclear blasts, these particles are thrust into the atmosphere,
and take a long time to dissipate.  In addition, these particles
may spread from sector to sector.

When a sector has fallout, during the update, things in that sector
may die, melt, whatever from the radiation.  The way it works is this:

1) All sectors that have fallout are checked, and things there are
   affected by the fallout.  People die, commodities melt, etc.  This
   includes anything on land units and on ships within that sector.

2) Next, fallout may spread from sector to sector, depending on the
   amount of fallout in the sector.  Note that fallout will spread
   outward from ground zero, in all directions, at a maximum rate of
   1 sector per update.

3) Lastly, fallout decays.  Any fallout that is left decays.  Decay
   usually happens in 1/2 life mode, which means 1/2 the given fallout
   in a sector (after spreading around) dies...

Finally, if you are reading this info page, it probably means that
you are trying to figure out what fallout is going to do to your
country.  Well, good luck, so are we. :)

.NA Flak "How flak works"
.LV Basic
This page describes flak, and how it works.
.s1
Flak is created from gunfire when enemy planes fly overhead.
.s1
The way that flak works when planes fly over a sector is:
.nf
 * Sector flak is fired.  Up to a maximum of 14 guns can fire
   before being scaled.
 * Land unit flak is then fired.  Up to a maximum of 14 guns can
   fire before being scaled.  Only 'flak' capable units will fire
   in this volley (see "info show"), and only the guns loaded onto
   a land unit are counted in the # of guns firing.
 * Ship flak is then fired.  Up to a maximum of 14 guns can fire
   before being scaled.
 * Defensive planes then intercept.
.fi
.s1
In all of the above flak rounds, once the maximum # of guns firing
has been determined, the # of guns is then scaled by your country's
tech factor, and then doubled.  So, for example, if you had 14 guns
firing, and have a tech factor of 35%, you would have a total of
(14 * .35) * 2 = 10 (after rounding) guns firing.
.s1
In addition, if you are pinbombing a land unit or a ship, when 
you make your bombing run, the specific unit/ship you are bombing
gets to fire flak at you again.  This number of guns firing flak
in these cases is NOT scaled after the number of guns is determined.
.s1
When a sector fires flak, the amount of shells required is the # of
guns fired divided by 2.  If not enough shells are available, either no flak
is fired, or the flak is reduced to the number of shells available.
Note that the shells are not consumed during flak fire, they just need
to be available.
.s1
When a ship fires flak, at least 1 shell must be available.
If no shells are available, no flak is fired.  Note that the shell is
not consumed during flak fire, it just needs to be available.
.s1
Land units use no shells when firing flak.  Any land unit with an
aaf rating of > 0 will fire flak when pin-bombed.
.s1
The formulas for determining the # of guns fired in a general volley
is:
.nf
Sector:
    guns = (guns in sector);
    if (guns > 14)
        guns = 14;

Ship:
    guns = 0;
    for (each ship in the sector)
        guns += min(guns, guns able to fire) * (techfact of ship) * 2;
    if (guns > 14)
        guns = 14;

Land unit:
    guns = 0;
    for (each land unit in the sector)
        guns += (aaf rating) * (techfact of unit) * 3;
    if (guns > 14)
	guns = 14;
.fi
.s1
Then, for each of the above general flak volleys, the # of guns is
scaled like so:
.nf
    firing = guns * (techfact of nation) * 2;

On specific bombing runs, the # of guns firing is determined by:

Ship:
    guns = min(guns, guns able to fire) * (techfact of ship) * 2;

Land unit:
    guns = (aaf rating) * (techfact of unit) * 3;

The # of guns in these cases are NOT scaled.

techfact is determined by:
    techfact = (50.0 + tech) / (200.0 + tech);
.fi
.s1
Once the number of flak guns firing has been determined, the planes
have to fly through it.  The plane may have to fly through flak up
to 4 times in each sector, depending on circumstances.  They are:
.nf

    1) Fly through general sector flak (if any)
    1a) fight in a possible dog-fight
    2) Fly through general ship flak (if any)
    3) Fly through general unit flak (if any)
    4) If pinbombing, fly through specific unit or ship flak (if any)
.fi
.s1
To figure out the damages that a plane takes each time it flys through
flak, the following formula's are used:
.nf

    flak = # of guns firing.
    flak = flak - (planes defense + 1);
    if (plane is stealthy)
        flak = flak - 2;
    if (plane is half stealthy)
        flak = flak - 1;
    if (flak > 8)
        mult = flaktable[15] * 1.33;
    else if (flak < -7)
        mult = flaktable[0] * 0.66;
    else {
        flak += 7;
        mult = flaktable[flak];
    }
    mult *= flakscale;
    damage = ((random number from 1 to 8) + 2) * mult;
    if (damage > 100)
        damage = 100;

    plane's eff = (plane's eff) - dam;
    if (plane's eff < 10%)
        plane is shot down
    else if (chance((100 - (plane's eff)) / 100))
        plane aborts mission
    otherwise the plane continues on it's mission

For the above, use this table:

    flaktable[0] = 0.20
    flaktable[1] = 0.20
    flaktable[2] = 0.25
    flaktable[3] = 0.30
    flaktable[4] = 0.35
    flaktable[5] = 0.40
    flaktable[6] = 0.45
    flaktable[7] = 0.50
    flaktable[8] = 0.50
    flaktable[9] = 0.55
    flaktable[10] = 0.60
    flaktable[11] = 0.65
    flaktable[12] = 0.70
    flaktable[13] = 0.75
    flaktable[14] = 0.80
    flaktable[15] = 0.85

and a flakscale of 1.75

(see SPECIAL NOTE below for the exception).
All of these numbers below are subject to change.
Execute the \*Qversion\*U command to get some of this information.
Ask the deity for the rest.
.s1
Each civilian or military eats 0.0005 units of food per time unit,
(i.e. 0.024 units of food a \*Qday\*U in non-Blitz Empire).
.\" eatrate * 86400 / s_p_etu

The ability of a sector to grow food is indicated by its \*Qfertility\*U.
Fertility values range from 0 to 100.

Food can be grown in any kind of sector although agribusinesses
are able to grow more food with fewer workers.
.s1
Every sector produces a base level of food according to the following:

.s1
Note that this means that although a sector with a fertility of 40
can grow enough food to support 160 people
.\" 40 * ofcrate / eatrate
at least 10 of them must be civilians.
In fact,
any combination of civilians and military
that meets the following two criteria will be self-sufficient:

(amount that gets harvested)
.in \\n(in
.s1
In an agribusiness an \*(iFadditional\*(pF amount of food can be grown.
That amount is calculated by the following:
.in +0.2i
.s1
An efficiency factor (effact) takes into account the state of repair
of the agribusiness itself (sector efficiency, effic) and
the technology level of your farmers
(the national technology level, tlev):
.s1
.ti +0.3i
effact = (effic * (tlev + 10)) / (100 * (tlev + 20))

The amount of additional food that the sector produces
in one time unit is:

Thus, a 100% agribusiness with a fertility of 50
and an educational level of 10
has an efficiency factor is 2/3;
one civilian can harvest 0.033 units of food per time unit
beyond the food normally produced in that sector.
This extra amount is enough to support 33-three other
people while one military can harvest 0.0066,
enough to feed 13 other people.

Note that if a ship doesn't have enough food, it will try to draw it from
supply sources (see info supply). If it still hasn't enough food, it will
attempt to grab unneeded food from any land units it is carrying.
.s1
Land units eat food as well, an amount based on the total number of military
in the unit (this is the efficiency times the number of mil needed to build
the unit). If a land unit doesn't have enough food, it will try to draw it
from supply sources (see info supply). If it still doesn't have enough, and
it is on a ship, it will attempt to get food from the ship.
.s1
The presence of food also affects the birthrate in Empire;
if there is no food in a sector no babies will be born.
A baby consumes 0.3 units of food in growing to adulthood.
.\" babyeat
However, babies are only allowed to eat half the food in a sector.
Thus if a sector could produce 25 new
civilians but only has 2 spare units of food,
(after the current population has eaten),
only three babies will be born and one unit of food will be left.

.s1
Guerrillas are created in several ways;
when a sector is captured by an enemy,
or when civilians riot for one reason or another
(starvation, no happiness, etc).
.s1
Guerrillas have a generally detrimental effect
on the well-being of your country.
Depending on the amount of military in the sector they \*Qinfest\*U,
they will either attack the military there
(but only if they have a good chance of winning),
blow up things (lowering sector efficiency),
or, if they are too badly outnumbered,
they will try and move to a different sector.
.s1
If there are no military in the \*Qinfested\*U sector
at the end of the update to break up guerrilla recruitment drives,
your civilians' loyalty will suffer.
If the sector is only occupied --
not completely owned by you, that is --
then it will revert back to the old owner,
renouncing the conqueror and returning to their old allegiance.
The guerrillas will then move on to \*Qconvert\*U more sectors.
Particular guerrilla bands will fight to the death,
or until you dissolve in disgust.
.s1
Guerrillas will attempt to \*Qrecruit\*U new followers
from semi-loyal sectors and from the uncompensated worker population.
Loyal civilians will resist these recruiting drives,
but uncompensated workers will always flock to the banner
of the guerrilla warrior.
.s1
The renowned guerrilla fighter Colonel (later Captain) Batguano
gave a talk to the special forces, which was later made into an
Armed Forces Technical Manual.
In it he states,

The first thing you learn is that the che are hardier than cockroaches,
eat like birds, and are simply invulnerable to gunfire and napalm.

There are two ways to handle the guerrilla problem;
one way requires high yield fusion weapons,
and then they only die when everything else in the sector is destroyed.
Unfortunately, collateral damage to civilian assets renders this
strategy negatory ... \* Col. Batguano then launches into
a tirade against the \*Qwimpy-assed liberals\*U which interfere with the
proper guerrilla suppression techniques \* ...
Almost every fully-populated area we moved into
had a few dozen of the little monsters,

Happiness is required for countries which have any sort of technology
or education at all, with greater levels being required as
the expectation (and tech/edu levels) of the populace increases.
A country with an unhappy population can expect a decrease in the
\*Qwork\*U of some sectors.
.s1
Also, the morale of your land units is determined by the happiness
of your people. The morale of a unit can be set by the player, but
the minimum level allowable is determined by happiness:

Thus, a nation with a happiness of 20 would have a minimum allowable 
morale level of 55%

The \*Qnation\*U command will display, among other things, your current
happiness level.

The procedure determining happiness level is exactly the same for
happiness as it is for education (see "info Education") except for the
fact that "happiness log base" is always 6.0 and "easy happiness" is
always 5.0.  New happiness is averaged with old happiness in the same
way that education is averaged except that happiness averaging has its
own line in the "version" output:
  Happiness is averaged over 48 time units.

.NA Hitchance "The chance of a projectile hitting its target"
.LV Expert
This page describes the chance of a mine, torpedo, ship anti-missile
defense, missile, or plane hitting its target.
.nf

Sea Mine hitchance
The chance of a ship hitting a mine at sea is (mines/(mines+20)). (For
example, with 20 mines, the chance of hitting one is 20/40 = 50%) The
damage is dependent upon the size of the ship and the spot that the
mine hits.  (see \*Qinfo Damage\*U).


Land Mine Hitchance
The chance of a land unit hitting a land mine is mines/(mines+35).
(For example, with 20 mines, the chance of hitting one is 20/55 =
36%).  See \*Qinfo Damage\*U to find out how much damage things take
from land mines.  Note that the chance of land units hitting land
mines is divided by 3 if the land units are accompanied by engineers.

When moving commodities (civs, mil, shells, etc) or transporting
planes, the chance is also dependent upon the weight being moved.
First the above chance is checked, and then a chance equal to (weight
/ 100) is checked.


Torpedo hitchance
The chance of a torpedo hitting its target is equal to:
  hitchance = 0.9/(range + 1)
where "range" is the range to the target.  If the visibility of the
ship firing is less than 6, then (5 - visibility) * 0.03 is added to
the hitchance.

Thus, the base chance of a sub hitting its target (before visibility
modification) is:

     Range   Chance
     0       90%
     1       45%
     2       30%
     3       22.5%
     4       18%
     5       15%


Ships anti-missile defense
If a ship has "anti-missile" defense capabiilty, then it will
intercept any marine missiles launched at ships within 1 sector of the
ship.  Only missiles belonging to a country you are "At War" with will
be intercepted.  Only ships which are at least 60% efficient will be
able to use their anti-missile defenses.  The chance of the ship
hitting the incoming missile it equal to:

  hitchance = gun * eff * tfact * 4.5 - (missile "def" value)
where
  gun = the number of guns the ship is allowed to carry
  eff = the efficiency of the shiip
  tfact = tech / (tech + 200)
where
  tech is the tech level that the ship was built at


Plane and missile hitchance
If the plane or missile is carrying a nuclear warhead or the target is
a sector, then the hitchance is 100%.  Otherwise, the following
procedure is used to calculate hitchance.

The formula for a plane or missile hitting its target depends on the
type of the target (ship, plane, land unit) and the "hardtarget" value
of the target (which represents how hard that target is to hit).

Ship:
  vis = the visibility of the ship (from 'show ship stats').
For a sub, we set vis = visibility * 4.
If the ship is at sea, then:
  hardtarget = (eff of ship) * (20 + speed/2 - vis)
otherwise:
  hardtarget = (eff of ship) * (20 - vis)
The hardtarget of a fleet is the hardtarget if the "easiest" target in
the fleet.

Land unit:
  hardtarget = (efficiency) * (10 + (sector defense) * 2 + speed/2 - vis)
The hardtarget of an army is the hardtarget of the "easiest" target in
the army.

Plane:
If the plane is in the air (satellite, icbm), then
  hardtarget = the "def" value of the plane.
otherwise if the plane is on the ground:
  hardtarget = 0

Once we have calculated the "hardtarget" value of the target, then the
chance of a plane or missile hitting its target is equal to:

  hitchance = acc - hardtarget

where
  acc = (efficiency) * (1 - 0.1 * tfact) * (1 - placc/100)
where
  tfact = (pltech - mintech)/(pltech - mintech/2)
where
  pltech = tech level of plane
  mintech = min tech level required to build plane
and
  placc = plane accuracy
and if the target is a ship and the plane is an ASW plane, then 
  placc = placc - 20
and if the target is a ship and the plane does not have tactical capability
  placc = placc + 35

Lastly we smooth out the bottom end of the hitchance curve.  If
hitchance is less than 20, then it is "belled up" using the following
curve:
  hitchance = 5 + 300 / (40 - hitchance).

On the other hand, you can just find out the hitchance by pinbombing
or launching a missile--the hitchance is always printed!  :-)

.LV Basic
.s1
INFRASTRUCTURE
.s1
The infrastructure of your sectors determines how well your sectors
defend, and how well you can move commodities and vehicles (land units)
through your sectors.
.s1
You can improve the "road", "rail" and "defense" efficiency of all of your
sectors, given that you have the correct commodities, enough mobility and
enough money.
.s1
The "road" infrastructure determines how well (i.e. the mobility cost)
commodities and non-train vehicles travelling through your sector are able
to move at both distribution time and while you are moving them by hand.
.s1
The "rail" infrastructure determines how well (i.e. the mobility cost)
trains are able to move through your sectors.
.s1
The "defense" infrastructure determines how well (i.e. the defense factor)
your sector defends itself.  There is a maximum amount that the sector
may obtain.  Use the "show sect stats" to see what the maximum values are.
.s1
So, what you can do, by using up some commodities, mobility and cash,
is to create a pseudo-highway network through non-highway sectors.  You can
still create highway sectors for just the designation fee of the sector,
but it costs you a whole sector to use it.  This is a trade-off for
both being able to use the sector and still move things through it at a
reasonable cost.
.s1
When you "improve" the infrastructure of your sectors, you are improving on
the efficiency of part of that sector (either road, rail or defense.)  By
improving it, it's statistics get better.  For roads and rails, that means
that the mobility cost to move through goes down.  For defense, that means
that you are building up the "defenses" of the sector towards the maximum
allowed (see "show sector stats" for the maximum values.)
.s1
Since infrastructure is on an efficiency basis, it takes damage just like
regular efficiency.  So, when a sector is shelled or bombed, the infrastructure
there is damaged in an efficiency based manner.
.s1
Infrastructure is also not affected by rebuilding the sector.  So, once
you build infrastructure, it stays in place until the sector is damaged in
some way.
.s1
Use the "sinfrastructure" command to see what the current infrastructure of
your country looks like.
.s1
Use the "improve" command to improve the infrastructure of your sectors.
.s1
To find out the required amounts of materials, mobility, and money
use the "show sect build" command.
.s1
Also, defensive infrastructure is not always improvable.  See the version 
info to see if the DEFENSE_INFRA option is enabled or not.  If it is not
enabled, the defense infrastructure of the sector is always the same
as the efficiency of the sector.  If it is enabled, you must improve your
sectors defensive values using the "improve" command.

(And it's usually out of date.)
.s1
Sector Updates
.s1
Several characteristics of the Empire game are dependent on
sector updates --
mobility, efficiency, mining of ore, generation
of production units, etc.
.s1
An understanding of the calculations
involved is often helpful in planning the timing of various
actions
and although it is unlikely that this description
is strictly up to date,
it should provide a feel for the overall philosophy.
.s1
All commodities in a sector are kept as \*Qshort integers\*U.
The program cannot have \*Qnegative commodity values\*U, so the
theoretical capacity of a sector is 32767, while in practice
it is actually 9999 (for formatting reasons).
While it is possible to move more commodities than 9999 into
sectors, production of commodities will not go
above the level of 999.
So, an update that produces 450 units of iron in a sector that already
has 800 units can at most add 199 units.

Several points are noteworthy:
.s1
\(bu The work done in a sector (ore dug up, efficiency growth,
population growth, products generated, etc) is dependent on the
product of time since last update and work force (\*Qwork\*U above)
while the accumulation of mobility is independent of work force.
.s1
\(bu If the population of a sector is very low it may never generate
any work at all due to conversion to integer truncation.
.s1
Ship Updates
.s1
Ships are also updated only when accessed however the mechanism is simpler.
The only characteristics that are changed by ship updates are
the mobility,
the efficiency, (if less than 100%).
the food, (and therefore the crew if starvation occurs),
the amount of oil,
and
plague status, (which can also change the size of the crew).
.s1
The algorithm is essentially:
.in +3
.nf
add etu to mobility (with a maximum of 127)
add etu to efficiency (with a maximum of 100)
add etu * civil * sector_oil / 10000. to oil if ship type is oil derrick
add etu * civil * sector_fertil / 10000. to food if ship type is fishing boat
feed the crew and passengers
    starve a few if not enough food
check for plague progress,
    (the same as in sectors except each stage lasts twice as long on a ship)
.fi
.in
.s1
Bureaucratic Time Units
.s1
There is one further update that is not handled in the sector
update routine; that is the update of bureaucracy time units (BTU's).
These are the numbers printed in brackets before the command
prompt.
Most commands given use BTU's, some use 1, some use 2 and some use
more, making BTU's a vital commodity.
The generation of BTU's is
dependent on the efficiency and the work force in the capital sector.
(see info BTU).

.NA Interception "How plane interdiction works"
.LV Expert
.s1
Each time an enemy plane (i.e. a plane owned by a country that your are
HOSTILE to or worse) flies into over a sector you own, planes you
have with the intercept ability will intercept them if:

.NF
a) The incoming plane is not stealthy, or is detected.
b) The sector is within 1/2 the interceptor's range (as modified
by rangeedit)
b) They have mobility
c) Their efficiency is 40 or more
d) They are at an appropriate place:
	1) planes without VTOL ability must be at an airport that
		is at least 60% efficient.

	2) planes on ships may only fly if the ship can operate
		that kind of aircraft.

e) There is petrol there equal to 1/2 the plane's fuel rating.
	(rounded down)
.FI
.s1
Before planes scramble to intercept incoming planes, any SAMs in range
will be launched.  One SAM is launched at each incoming plane that
cost at least $1000 to build.  See below for the damage that the SAM
does to the plane it hits.
.s1
Enemy planes will be intercepted by up to 1 more interceptor,
i.e. 1 plane will be intercepted by 2 (if available), 2 by 3,
3 by 4, etc. The highest
numbered planes intercept first. Incoming missiles will only be intercepted
by ABM's
.s1
Once the roster of attackers & intercepters is determined, attackers
and interceptors dogfight. First escorts & interceptors fight,
then planes being escorted & surviving non-aborted interceptors.
.s1
First, an attacker and a defender are chosen, then each plane on each
list fights once.
.s1
.L "Combat values"
.s1
The attacker's combat value is calculated by adding up his planes attack
value, and modifying it for efficiency, bomb-load, and stealth. The attack
value of the plane is multiplied times the plane's efficiency, but cannot
go below 1/2 of the plane-type's base value (as shown by show plane stats).
(If the plane's attack value
is 0, the defensive value is used instead, with a minimum of 1/2 the plane-
type's defensive value)
.s1
Two is subtracted if the attacking plane is carrying bombs.
.s1
If the plane is stealthy, stealth%/25 is added.
.s1
The defender's value is calculated in the same way, except that the
defensive value is always used.
.s1
.L Odds
.s1
Next, an odds ratio is calculated: (att/(def+att))*100.
.s1
.L "Combat Intensity"
.s1
Then, a combat intensity is rolled: (d20+d20+d20+d20)
.s1
.L Combat
For each point of combat intensity (or until both planes are dead),
a d100 is rolled. If the value is less than the odds, the defender
takes a casualty, otherwise the attacker takes a casualty.
.s1
Once all combat rolls have been made, the attacker and defender are
checked for aborting. If a plane is damaged below 80%, then it will
have a chance of aborting.  The chance to abort is (100-plane eff). (Example: a
plane at 70% has a 30% chance to abort.
.s1
Missiles intercepting die after the combat is done.
.L Example
.s1
Suppose that a fighter 2 (30% efficient, tech 154, attack value 7) is
conducting a recon mission. As it enters an enemy controlled sector, a
fighter 1 (100% efficient, tech 131, defense value 4) rises up to fight it.
The attacker's combat value is calculated:
.s1
.NF
1) 7 * (30/100) = 2.1 = 2

2) 2 is less than 1/2 the base attack value of an f2 (6), so the value
is changed to 3

3) The attacking plane is not stealthy. No modifier.

4) The attacking plane is not carrying bombs. No modifier.
.FI
.s1
The defender's defense value, calculated similarly, is 4.
.s1
The odds ratio is (3/(3+4)) = .429 = 43%
.s1
The intensity is randomly determined to be 30. A d100 is rolled 30 times.
Each time that is 43 or less, the defender takes a hit. Each time it is
44 or more, the attacker takes a hit.
.s1
In our example, the attacker takes 17, the defender 13, leaving them at
13% and 87% efficiency, respectively. The attacker has an 87% chance to
abort, and the defender a 13%. If neither aborts, the attacker flies on. If
both abort, the mission is over. If only the defender aborts, the attacker
will fly on to the next sector in his flight path (perhaps to have combat
again) If only the attacker aborts, the defender flies home with the
knowledge of a job well done.
.s1
.L ABM's
ABM's do not use the normal combat procedure. They simply have a %
chance of destroying an incoming warhead equal to their defensive value.
.s1
If you have land units in the enemy plane's target sector, your plane will
intercept the enemy planes AGAIN. If you have non-sub ships in the enemy plane's
target sector, your planes will intercept them yet again. If you own
the target sector, and have ships & units there, your planes will therefore
intercept them a total of three times in that sector. Note that a 'target
sector' is a sector that is the target of a bombing or para mission. Merely
having ships in a sector will not cause interception of planes flying over.

.NA Land-units "How to use land units"
.LV Basic
.s1
Land units are organized collections of mil (militia). They are considerably
more effective and cost-efficient than militia, and have many extra
abilities. With the addition of land units, mil are now more or less
considered to be militia instead of military, and are less important.
.s1
The way that military are incorporated into units are that the mil are
loadable commodities of the unit.  The offensive or defensive 
.s1
Commands for land units are generally similar to those of planes/ships, and
will usually start with 'l'. 
.s1
.L "Land unit characteristics"
.s1
Land units have some characteristics of both ships and planes, plus some
unique ones. Like both ships & planes, they have efficiency & mobility.
Like ships, they can carry cargo, may have/use fuel, and may be able to fire
guns at distant targets. Like planes, they have attack and defense values,
and may be able to act automatically to defend your country.
Let's look at a typical land unit:
.s1
.EX land *
.NF
   # unit type             x,y   a  eff mil fort  mu  fd tech retr rd xl ship
   0 inf   infantry        8,0      96% 100    0  93  24    0  42%  1  0
1 unit
.FI
.s1
This land unit is an infantry unit, located at 8,0. In many games, you will
start with 1-2 basic land units of this type. Some of the things about it are
familiar. It is 96% efficient, has 93 mobility units, carries 1 food, no fuel,
and is tech 0 and currently contains 100 mi. It carries 0 extra-light
planes, and is not on a ship. The 'a'
stands for army, and is just like fleets or wings, i.e. a way of grouping your
units. (See info \*Qarmy\*U for more information)
Fort is the level of fortification of the land
unit. The higher the fortification, the harder the unit is to hurt.
.s1
The 'retr' stands for retreat percentage. This
land unit must begin rolling morale checks in combat whenever its efficiency
goes below 75%. This is user settable in a range determined by the happiness
of the owning country. The happier your people are, the more determinedly
they fight. If, on the other hand, you \*Qwant\*U the unit to retreat easily,
you can set this to 100% or some other high number. (For information on
setting this, see info morale. For information on morale checks, see info
attack)
.s1
The 'rd' field is referred to as the unit's 'reaction radius',
and is the distance to which the unit can react to defend your country.
Basically, if an enemy attacks a sector close enough to the unit, it will go
to the threatened sector and fight, like a plane intercepting. If it survives
the attack without failing a morale check, it will return to the sector it
started from, just like a plane would. (For more information on reacting and
morale checks, see info attack) Just as you can use rangeedit to change the
range of your planes and control how far away they'll intercept, so you can
change the reaction radius with \*Qlrangedit\*U. Units with a base reaction
radius of 0, or those whose radius you have set to 0, will not react.
.s1
.L Cargo
.s1
Each land unit can carry cargo. The cargo display for land units is very
similar to that of ships, and is gotten with the \*Qlcargo\*U command.
.s1
.EX lcargo *
.NF
lnd# unit type     x,y    a   eff  sh gun pet irn dst bar oil lcm hcm rad

1 unit
.FI
.s1
The land unit is not carrying anything. Potentially, land units can carry any
of the commodities listed above. Unlike ships, they cannot carry mil, civs,
or uw's. Land units are loaded and unloaded using the lload command, which
works pretty much like the load command for ships. (See info \*Qlload\*U)
Units on ships can transfer supplies to/from the ships with the \*Qltend\*U
command.
.s1
.L "HQ's & Building land units"
.s1
Like planes and ships, land units are built in special sectors. For land units,
the sector is the headquarters sectors, designation !. Like other units,
they may require hcms and lcms, and will generally require money.
.s1
Some land units may require guns to build. All this info can be gotten with the
\*Qshow\*U command.
.s1
.EX show land build
.s1
.NF
                          lcm hcm guns avail tech  $
inf   infantry             10   5    0    40    0  $500
.FI
.s1
The infantry unit takes a total of 10 lcms, 5 hcms, and  0 guns to build.
Like ships and planes, units are built at a lower percentage, and 'grow' up
to 100%, and any unit with an efficiency of less than the build percentage
is dead. For land units, this minimum efficiency is 10%.
The build requirements for land units, like those listed above, are
for a 100% unit. Thus, the infantr1 would require 1 lcm and .5 hcms
(Fractional amounts are randomly rounded... i.e. .5 has a
50% chance of being 1 or 0. It'll all even out over time)
.s1
When 'growing', land units
require materials which must be present in the sector. The
amount of growth is calculated in the same fashion as planes/ships. Generally
a land unit can grow by up to 2x the ETUs per update. (See the \*Qversion\*U
command for exact maximums, as these are deity-settable) So, for example, in
a 32 ETU game, a land unit could possibly grow by 64% per update. For the
infantry unit shown above, this would require 6.4 lcms and 3.2 hcms.
If any of these things aren't present in the sector, the unit won't
gain efficiency.
.s1
.L "Repair of Land units"
.s1
Ships can repair themselves in any sector, and can use work from their crew,
or from a harbor they are in. Planes can only be repaired in airports, and
only use work from the airport. Land units can be repaired in HQ's, \*Qor\*U
in fortresses, and use the work of the HQ or fort. This means that front-line
units in forts will repair themselves each update, assuming that the
necessary materials and work are available. They can also gain efficiency
in other sector types, but at a much reduced efficiency (1/3rd normal gain)
.s1
.L "Land unit statistics"
.s1
Each land unit has certain vital statistics which show how it will 
operate. These are obtainable from the show command:
.s1
.EX show land statistics
.s1
.NF
                                       s  v  s  r  f  a  d  a  a        x

infantry                  1.0 1.5  60 23 15  2  1  0  0  0  0  0  0  0  0
.FI
.s1
The infantry unit has an attack multiplier of 1.0, and defensive multiplier
of 1.5. It has a vulnerability rating of 60, a speed of 23, a visibility of
15, spy value of 2, reaction radius maximum of 1, no firing range, no accuracy,
no firing damage, uses no ammo, has no aa fire, doesn't carry of use fuel,
and can't carry extra-light planes.
.s1
When attacking, a unit's value is expressed in 'mil-equivalents', i.e. 1
mil-eq is as strong as 1 mil. To find a unit's attack value, find the number of
mil currently in it, and multiply by the attack multiplier and efficiency.
In the case of our infantry unit the unit has an attack value of 96
(100*1.0*.96), and a defense value of 144
(100*1.5.96). Some units, like tanks, will have high attack multipliers,
and medium
defense multipliers. Some, like most infantry, will be better at defending than
attacking. Some, like artillery units, will be bad at both.
.s1
As time goes on, and your tech increases, the stats of your land units
will get better.  This reflects the technological breakthroughs you have
made in that you can now build better units of the same type.
.s1
The vulnerability of a unit determines how easy it is to hurt the unit by
shelling it, bombing it, or when it encounters land mines. The lower the
vulnerability, the better. Values range from 1-100.
.s1
Spd is the relative speed of the land unit. Land units move by marching (see
info \*Qmarch\*U), and use mob depending on their speed and the terrain they
are moving through. For more info and formulas, see info \*Qmarch\*U.
.s1
Vis is the visibility of the unit. This is a measure of how easy it is to
see/detect the unit. Lower is harder to see, and the numbers can range from
1-100 or so. When a land unit tries to use the \*Qllookout\*U command to look for
enemy land units/planes, its chances of success are affected by the target
units' visibility (see info \*Qllookout\*U for more details).
.s1
Spy is the other side of the equation, i.e. how well can the unit find things?
A unit with a low spy won't be very good at locating other units, and won't
be able to report much when it encounters them in battle. A high-spy unit
will be able to use the \*Qllookout\*U command with more chance of success, and 
will be able to more accurately report information about the units it runs
into in battle. (See info \*Qattack\*U for information about intelligence
reports) Units with radar capacity also use their spy value to determine how
far they can see. Spy values range from 0-127, with low numbers being most
common.
.s1
Don't confuse this spy value with the "spy" capability of a unit.  See
"info Spies" for more information.
.s1
Rad is the maximum reaction radius for the unit. When built, the unit will
have this as its reaction radius. If you change the reaction radius by using
the \*Qlrangedit\*U command, you will be able to select any value that is
between 0 and the maximum.
.s1
Frg is the unit's firing range. The unit can fire as far as the frg, modified
by the unit's tech. Accuracy is the unit's firing accuracy, and helps to
determine how much damage it will do, along with the dam of the unit. When
firing at sectors, damage is based solely on the damage. When firing in
defense of a sector, or firing at ships, damage is based on both acc and dam.
(See info \*Qfire\*U for more information)
.s1
Ammo is the number of shells a land unit uses every time it fires or
participates in combat. If the unit does not have enough shells when
firing, damage will be reduced proportionately. If a unit does not have
enough shells in combat, it will be out of supply, and have its combat
strength cut in half. (See info \*Qsupply\*U and info \*Qattack\*U for
information on supply and how it affects combat.
.s1
Aaf is the unit's anti-aircraft fire value. The higher the value, the more
damage the unit will do to planes flying overhead.
.s1
Fc/fu are the unit's fuel capacity and use. If the fc/fu are 0, the unit
does not need fuel to gain mobility. If the fc/fu are non-zero, the unit
will need fuel to gain mobility, and will use fu fuel whenever it fights.
(See info \*Qfuel\*U for information on fuel)
.s1
Xpl is the number of extra-light planes the unit can carry. Planes can
operate from a land unit in the same fashion as if it were a carrier.
Normally, extra-light planes are SAMs, so units can carry SAMs for
air-defense. This particular unit can't carry any.
.s1
.L "Land unit capabilities"
.s1
There are many different capabilities that land units may have. They may
be seen with the show command:
.s1
.EX show land capability
.s1
.NF
                          capabilities
infantry                  5f light assault
.FI
.s1
The command shows the cargos the unit can carry (5 food in this case), and its
abilities. See info \*QUnit-types\*U for a complete description of the
various capabilities.
.s1
.L Moving
.s1
Land units move with the \*Qmarch\*U command, which is pretty identical to the
navigate command. Marching units can run into land-mines, be interdicted, etc.
See info \*Qmarch\*U for more info. See info \*Qmission\*U for information on
interdiction.
.s1
.L "Units & ships"
.s1
Each type of ship is rated on the number of land units it can carry.
Land units that are 'light' can be loaded onto ships using the normal \*Qload\*U
command (see info load). Units that also have the 'assault' ability (see info
\*Qshow\*U and info \*QUnit-types\*U for explanations of abilities) can be
used in assaulting sectors. (See info \*Qassault\*U).
.s1
.L Supply
.s1
Units need supplies in order to attack. Each update, and each time they
attack, units will attempt to draw supplies. See info \*Qsupply\*U.
Really, I'm serious. If you don't read info supply, you'll die a horrible
death. I'm not kidding.
.s1
.L Fortification
.s1
Land units are able to \*Qfortify\*U themselves to better resist damage. Each
point of mobility spent increases the fortification level by 1, up to a maximum
equal to the maximum mobility of a land unit. A fully fortified unit takes one
half the normal amount of damage. Fortification is lost when the unit moves or
retreats. (Note that a reacting defending unit \*Qcan\*U have a fortification
value. This is an abstraction) Read info \*Qfortify\*U for more details.
.s1
.L Looking
.s1
Land units can use \*Qllookout\*U to look around. This command is analogous to the
look command used by ships. When llooking, land units have a chance to spot
other land units and also planes. Recon units tend to have better spy values,
and so are better at this.
(See info \*Qshow\*U and info \*QUnit-types\*U to
find out more about recon units).
.s1
.L Radar
.s1
Some units can use the \*Qlradar\*U command. This command works like the
radar command. Radar range is determined by the unit's spy value.
(See info \*Qshow\*U and info \*QUnit-types\*U to
find out more about radar units).
.s1
.L Engineers
.s1
Some land units have the 'engineering' ability. These units can do several
things. Engineers are the only units that can lay land-mines, and the only units
that can sweep them when moving (like a minesweeper). Attacking engineers
also halve the defender's mine bonus. Engineers can also use the \*Qwork\*U
command, which allows them to raise sector efficiency. (See info \*Qwork\*U)
They also tend to be quite expensive.
.s1
.L "Attacking & defending"
.s1
Info \*Qattack\*U has a complete treatment of this, but I will summarize here.
When you decide to attack a sector, you can use mil and units from adjacent
sectors. The attack value of your forces is the combined attack values of all
attacking land units, plus the number of mil coming in from adjacent sectors.
.s1
The defense value is equal to the mil in the defending sector, plus 
the defense values of any defending units in the sector, as well as any that
react and move there.
.s1
Friendly ships/forts/artillery units/planes can contribute
\*Qsupport\*U. Support starts at 1.0. Each friendly ship/fort/artillery unit/
plane that can help adds its damage/100 to the support. For example, if you
were attacking a sector, and a friendly battleship was close enough to fire
there, it could support you. If it would normally do 23% damage when firing,
it would add +.23 support, making your support number 1.23. The enemy also
gets support from all his stuff.
.s1
When all support is totaled, the attacker strength is multiplied by
the attacker's support to get the total attacker strength. The defender's
total strength is determined similarly. Both sides have their strength modified
by the terrain. (show sector stats will show the defensive value of a sector)
He can also get support
by having mine-fields in the sector (see info \*Qlmine\*U and info
\*Qattack\*U for more information). Planes support only if assigned to a
support mission. See info \*Qmission\*U for information on support missions.
.s1
Combat is done fairly normally, with a series of rolls for attacker/
defender casualties, until one side is dead or retreats. Land units take damage
after all mil on their side are dead, and each 'hit' on a land unit does 1 mil
damage. (Therefore, a unit that takes 100 mil to build would take 1% damage
when it suffers a casualty. A unit that takes 50 mil would take 2%, etc)
When a land unit's level of damage taken in a battle reaches it's 'retreat
level', it must begin taking morale checks. When it fails one, it will retreat.
Retreating attacking units go back to the sector they came from. Defending
units will attempt to retreat to an adjacent owned sector. If there are none,
the unit will take extra damage and continue fighting.
.s1
If the attacker wins, he captures the sector, and his mil/units will
move into the sector if he ordered that. If the defender wins a combat,
his units in the sector stay there. His reacting defending units that did not
fail a morale check return to their starting point. Defending units who
started in the sector stay in the sector.
.s1
In both cases, retreated units end up in the sector they retreated to.
.s1
.L "Units and retreating"
.s1
Ships can use the \*Qretreat\*U command to specify when and how they will
run away from trouble. Land units use a similar command \*Qlretreat\*U to
do the same thing. See info \*Qlretreat\*U for more details.

.NA Maintenance "The cost to maintain ships, planes, and land units."
.LV Expert
During each update, nations must pay to maintain their units, ships and planes.
.s1
The cost to maintain a ship, or land-unit is:
.NF +8
	.001 * cost of thing * ETUs/update
.FI
.s1
The cost to maintain a plane is:
.NF +8
	.001 * cost of thing * ETUs/update + 5 * mil_cost * crew
.FI
.s1
Note that this cost can be changed by the deity.
.s1
Also note that if you have purchased high-tech items, and your tech
is not at least 85% of the item's tech, you are charged double
to maintain the item.
.s1
Also note that engineering land units costs 3 times what
normal units cost, after the tech is figured in.
.s1
If you can not afford to pay maintenance costs or you choose not to
pay them (see info budget) then your unit will lose ETU/5 points of
efficiency.  Thus, if you were playing in a 60 ETU game, and you did
not pay your maintenance costs for a 50% frigate, then the frigate
would drop to 38% efficiency.

.NA Mobility "How much mobility stuff costs"
.LV Expert
.nf

Mobility represents the amount of time and energy it takes to do
something.  In "Real Life" a ground offensive takes hours.  In Empire,
it takes less than a second.  Now the way Empire *could* work would be
for you to give your troops "orders" and then wait a "realistic"
amount of time for them to carry these orders out.  But who wants to
type "nav 15 yh" and then wait 30 minutes for the ship to get there?
Certainly not you!  That's why mobility was invented.  Every update,
all of your units and sectors get more mobility, and that means that
enough time has passed for you to be able to do more stuff!

In Empire, four things have mobility: sectors, ships, planes, and land
units.  You can see how much mobility each of these gets every update
in the output of the "version" command:
                                Sectors Ships   Planes  Units
Maximum mobility                127     127     127     127
Max mob gain per update         60      120     90      90

If the mobility cost for something is a fraction, for example 2.4,
then there will be a percentage chance that the actual cost is rounded
up or down.  In our example, there would be a 60% chance that 2.4 is
rounded down to 2 and a 40% chance that it is rounded up to 3.

-- Land Units --
Land units are charged mobility for the following actions:

1. Fighting
See "info Attack" for the mobility cost to attack.

2. Fighting rebels
For each 2 points of efficiency a land unit looses fighting rebels at
the update, it looses one point of mobility.

3. Fortification
To fortify ("dig in") a land unit costs one point of mobility per
point of fortification.

4. Converting civs
Security units are charged 10 mobility every time civs are converted
in a sector they are in.

5. Laying mines
A land unit is charged one point of mobility for every land mine laid.

6. Work
The increase in efficiency depends on mobility used. It costs a 100%
efficient land unit 6 mobility to raise a sector 1% efficiency.  Less
efficient land units are charged proportionally higher amounts of
mobility.  For example, a 50% land unit would be charged 12 mobility
to raise the efficiency of a sector by 1%.

7. Supply
When supply is drawn from a supply unit, that unit pays the mobility
cost to move the goods to the destination sector.  That cost is the
same as it would cost the sector to move the goods using the "move"
command.

8. Marching, reacting or retreating
The mobility cost for a land unit to march, react or retreat is:
  (path cost) * 5 * 480 / (unit speed)
See "Path Cost" below for the path cost formula.  Note that reactung
land units only pay mobility to move "to" the attacked sector; they
return to their start sector for free.  Land units on "reserve"
mission only pay half the mobility cost to react.

Note that the efficiency of a land unit does not affect the mobility
costs it pays to march, unless the unit is a supply unit.  Then the
mobility costs are proportional to the efficiency of the unit.

9. Shell damage
When a land unit is shelled, its mobility goes down in exactly the
same way that its efficiency goes down (see "info Damage").


-- Planes --
Plane mobility can never go below -32.  Planes are charged mobility
for the following:

1. Air combat
For every two points of damage the plane takes from air combat, the
plane looses one point of mobility.

2. Launching satellites
A satellite is charged one point of mobility for each sector it passes
over in its launch trajectory.

3. Flying
The mobility cost for a plane to fly is:
  5 + (flight cost) * (distance flown) / (max distance plane can fly)

For excorts and interceptors, the flight cost is:
  10 / (plane efficiency)
For all other flights, the flight cost is:
  20 / (plane effciiency)
For planes flying on an air defense mission, this cost is cut in half.

4. Land mine, pinbombing, a-sat, and nuclear damage
A land mine, pinpoint bomb, anti-sat missile or nuclear detonation
will damage the mobility of the plane in exactly the same way that the
efficiency of the plane is damaged (see "info Damage").


-- Ships --
Ships are charged mobility for the following:

1. Firing a shell
The mobility cost to fire a shell is 15, unless the NOMOBCOST option
is enabled in which case ships are charged nothing.

2. Firing a torpedo
The cost for a ship to fire a torpedo is one half of the cost for it
to move one sector.

3. Boarding a ship from a ship
See "info Attack" for the mobility cost to board a ship from a ship.

4. Navigating and retreating
The mobility cost for a ship to navigate or retreat is:
  (sectors travelled) * 480 / (ship speed)
where
  ship speed = (base speed) * (1 + (tech factor))
  base speed = max(0.01, efficiency * speed)
  tech factor = (50 + tech) / (200 + tech)

5. Shell damage
When a ship is shelled, its mobility goes down in exactly the same way
that its efficiency goes down (see "info Damage").


-- Sectors --
Sectors are charged mobility for the following actions:

1. Converting civs
Each civ converted costs 0.2 mobility.

2. Shooting civs & uws
The mobility cost to shoot civs or uws is
  (number shot + 4) / 5

3. Enlisting mil
The mobility cost for enlisting mil depends on what fraction of the
civs present you are enlisting:
  (new mobility) = (old mobility) * (1 - newmil / (starv civs))

4. Fighting
See "info Attack" for the mobility cost of attacking.

5. Moving commodities
Sectors move commodities in the "move" and "explore" commands, when
"supply" is drawn from them, and when they "deliver" and "distribute"
at the update.

Mobility is used from the source sector when moving.  Mobility used is
a factor of the commodity involved, the amount of the commodity, the
types of the sector and dist sector, the efficiency of both, and the
cost of the path to the destination sector.  When the move is
finished, move reports the total mobility used, and the amount of
mobility left in the sector.

The exact formula is:
  mob cost = (amount) * (weight) * (path cost) / (source packing bonus)

If the movement happened at the update, then the cost is:
  delivery cost = (mob cost) / 4
  distribute cost = (mob cost) / (10 * (destination packing bonus))

Weight
Each commodity has a weight:
  bar        50
  gun        10
  rad         8
  dust        5
  uw          2
  other       1

Packing Bonus
Some sectors are better at moving certain commodities than
others. This ability is known as their packing bonus. These sectors
only get these bonuses for moving items "from" them--not for moving
items "to" them. If the sector is less than 60% efficient, it doesn't
get its packing bonus.  Here are the packing bonuses:
        warehouse   harbor   bank   city*
  mil          1        1      1      1
   uw          2        2      1      1
  civ          4        4      1     10
  bar          5        5      4      1
other         10       10      1      1

* Note that If the BIG_CITY option is enabled, then 'c' sectors stand
for 'city' sectors, they can hold 10x as many civs, and they get a 10x
packing bonus for moving civs.

Path Cost
The path cost is the cumulative mobility cost of moving through each
sector in the path. The cost to enter a sector is based on the
sector's type and efficiency. All sectors cost 0.4 to move into when
they have a 0% road factor, except for mountains which cost 5.0 at 0%.
The mobility cost to move into a sector goes down linearly as the
road efficiency increases.  This represents the construction of roads.

You can also build railways to make the moving of trains faster.  When
marching trains about, the rail factor is used.  Otherwise, the road
factor is used.

See "info improve" for more information on improving the efficiency
ratings of your sectors, and see "info sinfrastructure" for information
on showing the infrastructure of your sectors.

See "info Infrastructure" for more general information on Infrastructure.

Update mobility bonus
Commodities get moved at the update through delivery and distribution.
All goods moved this way get their mob cost divided by 4 for deliver,
and 10 for distribute.  Furthermore, commodities distributed into a
harbor or warehouse get the warehouse packing bonus (normally, packing
bonuses only apply for the type of the source sector and not the type
of the destination sector).  These two bonuses represent the fact that
moving goods through an established distribution network is more
efficient.

6. Transporting planes or nukes
The weight of a plane is lcm + 2*hcm.  The weight of a nuke is the
number of "lbs" it has (from "show nuke stats").

7. Shell damage
When a sector is shelled, its mobility goes down in exactly the same
way that efficiency goes down (see "info Damage").

.NA Plague "The Plague"
.LV Expert
.s1
Plague is used in Empire to symbolize all forms of disease and is
the only health hazard associated with the Empire game,
(ignoring it's effects on the players).
The characteristics of plague are, therefore,
a compromise of disease features (or \*Qbugs\*U).
.s1
Note that if the NO_PLAGUE option is in use, a kindly deity
has wiped out the plague for you. If not, worry about it.
.s1
All of the timelines below are based on a game with 32 ETU updates.
.s1
The Empire Plague takes between 96 and 189 time units to
run its course on land,
(i.e., 2 to 4 days in any particular sector/ship/land unit
if an Empire time unit is 1/2 and hour.)
In so doing the plague goes through three stages:
.s1
.in +3
.ti -3
Stage I -- The gestation or incubation phase
in which no symptoms appear.
Sectors or ships that are in this stage of the plague
are indistinguishable from healthy sectors or ships.
This stage lasts 32 to 63 time units,
(less than a day and a half).
.s1
.ti -3
Stage II -- The infectious phase in which the symptoms first appear --
orange blotches on the face and hands,
sometimes accompanied by grey stripes on the genitalia,
itching of the liver and spleen,
an uncontrollable fear of ripe tomatoes, etc.
During this phase the plague is extremely communicable;
for example, a simple delivery from an infectious sector
will infect the destination sector.
.s1
.ti -3
Stage III -- The terminal phase in which people die,
often in the act of fleeing from (real or imagined) tomatoes.
The number of people that die is roughly inversely proportional
to the research level of the country (plus 100).
.in -3
.s1
All three phases are of roughly equal average duration,
(about 48 time periods or 1 day).
.s1
Plague usually arises in countries with high technological development
and comparatively little medical research.
It arises specifically in sectors with high population density
and low efficiency.
.s1
Recently archaeologists have uncovered a treatise
by a Dr.\ M.\ Welby entitled
\*QDemographic considerations and the Empire Plague\*U.
In part it states:
.s1
.in +0.8i
.ev 2
.ll 5.5i
It appeared that our original hypothesis
based on the high percentage of Lumbagan Legionnaires
among the afflicted had led us down a blind alley
and that if we were to solve this complex puzzle
before the end of the series in the spring
\*[possibly a reference to the series of tests
leading to the mysterious \*QNeilson Rating\*U\*]
we would have to turn to other disciplines for help.
It was only by the merest lucky coincidence
that as I drove home one evening ...
\*[here Dr. Welby relates an amusing anecdote
about a Brownie Scout and the director of a film
entitled \*QClose Encounters of the Third Grade\*U\*] ...
leading us to the following amazing formulation
of the relationship between medical research,
technology, population, standard of living and the Empire Plague:
.ll 6.5i
.ev
.in
.s1
.NF +0.4i
likelihood   civ + mil + uw   t_level + (iron + oil + rad * 2) / 10 + 100
    of     = -------------- * -------------------------------------------
  plague           999               r_level + effic + mobil + 100
.FI
.s1
Later formulations of this relationship show great similarity
to his statement (see \*Qinfo Innards\*U).
.s1
Many researchers have commented on the surprising lack of correlation
between food supply and plague outbreak.
.s1
Fortunately, the plague is only infectious while the sector is
actively battling the plague (Stage II).  The most effective method
for curing plague has been to isolate the sector by stopping all
distribution, deliveries, movement, etc.  originating from the sector
once an outbreak has been spotted.
.s1
This includes loading and unloading of ships and land units (since
they can, of course, carry plague), allowing explorations out of the
sector, moving commodities out of the sector, distribution or
deliveries from the sector, etc.  Basically, any people or commodities
that originate from a sector actively battling plague will cause the
destination sector (or ship or land unit) to become infected.
.s1
Once an outbreak has been spotted, the plague takes on an infectious
state at the next update.  There is very little time to isolate the
sector and limit deaths caused by plague.

.NA Plane-types "Description of different kinds of planes"
.LV Basic
The general plane types currently available in Empire are:
.s1
.NF
fighter  A general offense/defense plane. Historical examples include
         the FE.2B, the Sopwith Snipe & Camel, the Nieuport V-XVII, the
         Spad, and the Fokker planes. From WWII are the Me-109, the
         FW-190, the English Spitfire & Hurricane, the Japanese Zero,
         the American P-39, P-40, P-38, and the Soviet Yak series.
         Later planes include the Me-262, the Gloster Meteor, P-80,
         Mig-15. Korean War vintage planes are the F-87 Sabre, F-100
         SuperSabre, and the Mig-17. Vietnam Era planes are the F-4 &
         Mig-21. Later, NATO & WP models include the F-16 & F-15 and the
         Mig-23, 25, and 29.

         The main points of similarity are: 1 or 2 high performance
         engines, a single pilot, and plenty of guns/missiles. Duties
         include patrol/interception, escort, and light bombing.

escort   These are planes optimized for escorting, with superior range,
         sometimes at the expense of fighting capacity. Examples are
         the Me-110 & the P-51. Note that this type is relatively rare,
         as long range heavy bombing was rare.

naval
fighter  These planes all sacrifice range and/or fighting power in order
         to fit on a carrier and carry the gear necessary to operate
         from one. Examples are the series of Short biplanes built in
         Britain, the Sopwith Baby & Cuckoo, the Gloster Gladiator, the
         American Wildcat & Corsair, versions of the Japanese Zero, the
         F8 Corsair, the F-4, F-14, and F-18. Many of the planes were
         multi-role, due to the relatively small plane capacity of their
         carriers. They were almost always inferior in performance to
         land fighters. Many of them carry dual engines.

light
bomber   These planes are tactical bombers, suited for strafing, combat
         support, etc. These range from the first trench bombers, such as
         the Junkers J-I and the Sopwith Snark & Dolphin, the Ju-87
         Stuka, the American P-47, various ground-attack versions of the
         Yaks, the Japanese Val and Kate, the British Typhoon, and many
         others.  Modern versions are the A-3 SkyWarrior, the A-4
         Skyhawk, the A-6 Intruder, the Su-22 Frogfoot, the Su-27, and
         various British models. A modern and most effective example is
         the A-10

         The common factors are maneuverability, the ability to take
         damage and still fly, and the ability to hit targets precisely.
         (Either through low-speed bombing, dive-bombing, or rocket or
         guided bombs/missiles) Their performance against fighters of
         any sort is poor, with few exceptions (notably the P-47, which
         was designed as a fighter, and used as a ground-attack plane
         due to its toughness) Many are naval, or have naval versions,
         since the requirements of a naval plane do not affect them as
         greatly as fighters.

heavy
bomber   These planes are build for long range and great load-carrying
         ability, and the ability to defend themselves against fighters.
         (Although that never worked more than middling well) Examples
         are the Handley-Paige bombers of WWI (especially the O/400), the
         German Gothas and Giants, the B-17 Flying Fortress, the B-24
         Liberator, the B-29 SuperFortress, the Avro Lancaster, the Short
         Sterling, and the Vickers Wellington, as well as the more modern
         B-36, B-47, B-50, B-52, B-1, and the Soviet Ant-4, Tu-20 Bear,
         Tu-2? Backfire, and others.

         The common factors are the extreme range, the ability to carry
         several tons of bombs, the wide range of defensive armament, and
         four engines.

medium
bombers  These were basically an intermediate stage between the light &
         heavy bomber, and were used for both purposes. Examples are the
         He-111, the Do-17, the B-25 Mitchell, B-26 Marauder, the A-20
         Havoc, the Avro Manchester, Armstrong Whitworth Whitely, the
         Russian Il-4 & I-15, and the Japanese Betty & Sally.

         These planes were essentially compromises, and were phased out
         as time went on. They could not bomb as precisely as a light
         bomber, nor as heavily as a heavy bomber.
      
transports

         Initially, these were basically similar to civilian airliners.
         They could carry supplies or troops. (In Norway, the Germans
         captured airports and flew in troops) Later, they were used for
         paratroop landings. Eventually paratrooping became too dangerous
         for these planes (with the introduction of SAMs) and they were
         replaced by helicopter assault, with the transports going back
         to carrying supplies and equipment.

transport
helicopters

         These were made to transport assault troops. They also carry
         supplies & wounded, but their main duty was to deliver troops
         with greater precision, rapidity, safety, and cohesion than was
         possible with paratrooping. (They were also to replace the
         landing craft, as the Marines looked at the odds of an invasion
         fleet standing up to nukes)

attack
helicopters

         These supplement the light bombers, and specialize in the very
         precise application of firepower, as well as evading
         interception, by use of terrain.

recon
planes &
satellites

         These provide precise information about enemy troop dispositions
         and movements. The first recon planes had no protection. Then,
         it was attempted to make them un-interceptable. This was done by
         simply being faster than anything the enemy had, such as the
         stripped down British Hurricanes, US P-38's & P-51's, or German
         FW-190's or Blitz-Bombers. Later, emphasis shifter to also being
         able to fly higher, as with the U-2 & SR-71. These planes are
         largely superseded by satellites now (for good or ill).

ssm's
& icbm's

         The first ssm's were used as strategic harassing weapons, and
         were almost useless. (German V-1 & V-2) There were also combat
         rockets, such as the Russian Katayusha's and the German
         Nebelwerfers, but these were essentially similar to artillery.
         The first true SSM's were the Russian missiles in the 1950's,
         such as the Frog. They were intended to deliver nuclear or
         chemical warheads at medium ranges, and to be un-interceptable.
         Later missiles increase payload & range.

         However, since we've artificially restricted the blast effects
         of nuclear weapons, I am merging these in with tactical
         missiles. (no need for an icbm unless you've got big nukes)

marine
missiles
         These are modern smart-missiles. They are naval weapons, such
         as the Harpoon, Penguin, Exocet. They are accurate missiles which
         may be launched at ships.

sam's
         The first sams were nuclear-tipped, and intended to break up
         large attacking bomber forces. Later, they were made smaller
         and more accurate, and were intended to hit single targets
         at any speed or altitude.

abm's    These are to shoot down missiles, and are mostly fantasy.

asw
planes   These are either long-range bomber type aircraft, with some
         sort of equipment for locating & killing submarines, or also
         helicopters, able to fly from most naval vessels.
.FI
.s1
These plane types differ in their fundamental capabilities;
some can fly bombing missions,
other carry cargo, others exist to shoot down other planes.
Missiles are special;
they are planes which fly one-way missions
and cannot be shot down by opposing planes.
.s1
The technology level at which the plane was built is very important.
The same model plane built at a higher tech level
will outperform the planes built at a lower tech level.

.LV Basic
.s1
Many Empire sector types exist specifically
to turn \*Qraw\*U materials into products.
Some of those products may, in turn,
be considered raw materials for other industries
which produce other products.
.s1
This table gives the constituents and costs for each type of product.
.s1
NOTE: All costs given in the table are for 100% production efficiency.
Many processes depend on technology level
or educational level of the country;
a note like \*Qp.e.=(tlev+10)/(tlev+20)\*U means
that a country with a technology level of 0
has a production efficiency of 50%
and will only produce one-half of the specified product amount
for the given costs,
whereas a country with a technology level of 100
will have a production efficiency of 92%.
.s1
In addition, some sectors don't produce raw materials as well as others,
and some produce much better than others.  Use the "show sector capabilities"
command to see production efficiencies and other useful information on
producing sectors.
.s1
The rate at which constituents are turned into products
is governed by the \*Qwork\*U accrued to a sector
(see \*Qinfo Innards\*U) divided by the units of constituents
per unit of product.
E.g., it takes 3 units of \*Qwork\*U to produce 1 shell;
2 units to incorporate the light construction materials
and 1 unit for the heavy.
\*QNatural resources\*U such as fertility
count as one unit of constituents;
e.g., it takes 1 unit of work per unit of food produced.
.s1
.in \w'technology\0\0'u
.L shells
Shell production efficiency depends on technology level;
p.e.=(tlev-20)/(tlev-10)
Shells cost $3 each to manufacture.
Each requires 2 units of light construction materials
and 1 unit of heavy construction materials.
You must have a minimum technology of 20 to produce shells.
.L guns
Gun production depends on technology level;
p.e.=(tlev-20)/(tlev-10)
Guns cost $30 each to manufacture.
Each requires 5 units of light construction materials,
10 units of heavy construction materials,
and 1 unit of oil.
You must have a minimum technology of 20 to produce guns.
.L iron
Iron ore production depends on mineral content in mines.
Extracting iron ore is free,
and the mineral content of the sector is not depleted
by mining iron.
.L dust
Gold dust production depends on gold mineral content in gold mines.
Extracting gold dust is free,
but the gold mineral content of the sector is depleted
by mining gold dust.  In addition, mountains may sometimes produce
gold dust as well.  The efficiency of mountains producing gold dust
may not be as good as gold mines.  Use the "show sector capabilities" 
command to see the production efficiency of sectors.
.L bars
Gold bars are produced in banks.
Gold bar production depends on gold dust in gold mines.
Gold bars cost $10 to produce and require 5 units of gold dust each.
.L food
Food production efficiency depends on technology level
and the fertility of the sector;
p.e.=(tlev+10)/(tlev+20).
Growing food is free,
and the fertility of the sector is not depleted by growing food.
.L oil
Oil production efficiency depends on technology level
and the oil content of the sector;
p.e.=(tlev+10)/(tlev+20).
Pumping oil is free,
but the oil content of the sector is depleted
by extracting and refining oil.
.L petroleum
Petroleum production depends on technology level;
p.e.=(tlev-20)/(tlev-10).
A unit of petroleum costs $1 to manufacture.
Every 10 units of petroleum require 1 unit of oil to produce.
You must have a minimum technology of 20 to produce petroleum.
.L lcm
Light construction material production efficiency
depends on technology level;
p.e.=(tlev+10)/(tlev+20).
Producing lcms does not cost money, but requires 1 unit of iron ore. 
.L hcm
Heavy construction material production efficiency
depends on technology level;
p.e.=(tlev+10)/(tlev+20).
Producing hcms does not cost money, but requires 2 unit of iron ore. 
.L rad
Radioactive material production efficiency depends on technology level,
which must be at least 40.
p.e.=(tlev-40)/(tlev-30).
Producing rads cost $2 per ton,
and depletes the uranium content of the sector.
.L education
A unit of education (a \*Qclass of graduates\*U),
costs $10 to produce and requires 1 unit
of light construction materials (see "info Education").
.L happiness
A unit of happiness (\*Qhappy strollers\*U),
costs $10 to produce and requires 1 unit
of light construction materials (see "info Happiness").
.L technology
Technology production efficiency depends on education level;
p.e.=(elev-5)/(elev+5).
A unit of technology (a \*Qtechnological breakthrough\*U),
costs $5 times the number of ETUs per update
to produce, and requires 10 units
of light construction materials,
5 units of oil and 1 unit of gold dust.  For more details about how
technology level is calculated from technology units, see "info Technology".
.L research
Research production efficiency depends on education level;
p.e.=(elev-5)/(elev+5).
A unit of research (a \*Qmedical discovery\*U),
costs $90 to produce and requires 10 units
of light construction materials,
5 units of oil and 1 unit of gold dust (see "info Research").

.NA Research "How Research level is calculated each update"
.LV Expert
.sp
.s1
If the RES_POP option is in use, 
the research level of a country determines the maximum number of civilians,
mil, and uw's
that can live in a sector. The maximum then is:
.s1
.ti 3
400 + 600 * ((research*4 + 50)/(research*3 + 200))
.s1
So, for example, at 0 research, after an update, the max you
could have in a sector would be 550 civs, 550 uws, and 550 mil.
Note that in the case of captured sectors,
the research level of the current owner governs, even if the old
owner of the sector had a higher/lower research.
.s1
If, after population growth, there are more civs than the limit, the
excess are lost. Uw's & mil work the same way, each being individually
limited.
.s1
The research level also affects the likelihood of plague outbreaks.
(Unless the NO_PLAGUE option is used, of course)
.s1
The \*Qnation\*U command will display,
among other things,
your current research level.
.s1
The procedure determining how much your research level goes up every
update is exactly the same for research as it is for technology
(see "info Technology") except for the fact that "research log base"
is always 2.00 and "easy research" is always 0.75.  But besides this,
research bleeds, decays, and leaks in exactly the same way as technology.

.NA Sector-ownership "Sector ownership"
.LV Basic
.s1
In order to own a sector, you must have at least one of the following
present in the sector:

.NF
1) mil
2) a land unit
3) non-captured civilians
.FI

.s1
If at any time you do not have at least one of those 3 things in a sector,
you will lose control of it.
If you are not the old owner at the time you lose the sector,
it will revert to the old owner.  Otherwise it will
revert to the deity, country #0, even if another country's land units
are present in the sector.
If there are no people at all in the sector, it will revert to the deity.
.s1
Note that this means that if you attack a sector and do not move in,
you will not gain possession of it. If there are civilians in the sector,
the sector will revert back to the original owner. If there are no civilians
in the sector (and no mil or units, because you just killed them), the sector
will revert back to the deity.
.s1
Similarly, if you abandon a sector, it'll revert immediately.

BASICS
.s1
SEA - Sea sectors form natural barriers that can
only be crossed by ships, (made in harbors, below),
or spanned by bridges, (also below).
You can not designate anything else to be sea
nor can sea be designated to be anything else.
.s1
MOUNTAIN - Mountain sectors form another natural
barrier that cannot be redesignated; however, they can be
moved through (at great expense in terms of mobility units).
In an emergency, they can be used as capital. See \*Qinfo capital\*U
for more information.  In addition, mountains can only hold a maximum
of 1/10th the civilians and uncompensated workers that other sectors
can normally have.  And military, civilians and uncompensated workers that
will actually produce anything there are also limited to 1/10th.
.s1
SANCTUARY - Sanctuary sectors are created when
a new nation is created.
They are inviolate in that no one can fire at them or attack them.
This protection ends
when the new country first moves out of the sanctuary
(called \*Qbreaking sanctuary\*U); the sector then becomes a capital.
NOTE: in games with multiple sanctuaries per country ALL sanctuaries
become capitals when any one does!
.s1
WASTELAND - This is the result of the explosion of a nuclear device.
Wastelands are uninhabitable forever.
.s1
WILDERNESS - Most of the world is wilderness
at the beginning of the game.
Wilderness has no particular attributes;
you can move into it if unoccupied, thereby
making it your territory, but will probably want to
designate it as something else once you own it.
.s1
PLAINS - Plains sectors form another natural barrier that cannot
be redesignated.  They can be occupied and moved through however.
In addition, plains can only hold a maximum of 1/20th the civilians
and uncompensated workers that other sectors can normally have.
And military, civilians and uncompensated workers that
will actually produce anything there are also limited to 1/20th.
.s1
CAPITAL - Capitals are the source of bureaucracy time units (BTU's).
They accrue in proportion to the efficiency
of the capital and the number of civilians at work in it.
(see info BTU).
Most commands use up BTU's,
(see \*Qlist of commands\*U for numbers of BTU's used per command).
A nation may only have one active capital at a time
(although many sectors may be designated as capitals).
The capture of a capital will result in the loss of money from
the victim nation (see info capital),
Capitals are twice as efficient at defending
against attack as other sectors (except fortresses).
Use the capital command to make a capital the active one.
In a pinch, mountains can be used as capitals. They generate
very few BTU's, and represent being 'holed up in the mountains',
perhaps like Pancho Villa.  Note that if the BIG_CITY option is
enabled, then 'c' sectors stand for 'cities' and can hold 10x as many
civs.  They also get a 10x packing bonus for moving civs, and require
a certain number of lcm's, hcm's, and $$ to build (see show sect build).
.s1
PARK - Parks are provided solely for the convenience of the 
people.
Parks require construction materials to provide maintenance 
services and
add to a nation's \*Qhappiness\*U level.
The conversion of \*Qraw\*U materials takes place automatically
at a rate dependent on the efficiency of the sector,
the presence of the required materials,
and the number of workers in the sector.
.s1
.s1
.ce
COMMUNICATIONS
.s1
HIGHWAY - Whenever you move civilians, ore, gold,
etc, mobility units (\*Qmob\*U on the census) are consumed dependent
on how far and how much you move.
However if the movement is through 100% efficient highway
it costs much less to move.
.s1
RADAR - Radar stations can scan the surrounding
area (up to 16 units away for 100% efficiency) and generate
a radar plot identifying sector types at distances up to 1/3
their range and ships up to their full range.
.s1
BRIDGE HEAD - Bridge heads are the land based ends of bridges.
They, like harbors, turn construction materials into
bridge spans; see \*Qinfo build\*U for the details of this process.
and are much like highways except for three things:
.br
(1) Bridge spans provide food through fishing,
(the fertility can be thought of as fish-count).
(This is deity-settable, however.. in many games, bridges do not
provide food. Be sure to ask)
.br
(2) Bridge spans must maintain at least 20% efficiency or else they
collapse.
.br
(3) If the only bridge head supporting a particular bridge span is
redesignated as something else the bridge span will collapse.
(If the EASY_BRIDGES option is in use, bridges do not need bridgeheads.
Check \*Qinfo build\*U for the details)
.s1
BRIDGE TOWER - Bridge towers are like bridge heads you can build
out in the ocean.  You can only build bridge towers from a bridge
span, and in open water (not adjacent to any land or other bridge
towers.)  From a bridge tower, you can build other bridge spans.
The BRIDGETOWERS option must be enabled for you to be able to
build bridge towers.
.br
Bridge towers must maintain at least 20% efficiency or else they
collapse.  Any bridges connected to the tower will collapse as
well, unless held up by another adjacent structure (bridge head,
bridge tower or land if EASY_BRIDGES is enabled.)
.s1
.s1
.ce
FINANCIAL
.s1
BANK - Banks are used for smelting and storing gold bars.  
They include a smelter to refine gold dust into gold bars.
While the bars are stored in the bank the busy little bankers 
invest them and return a profit on their use.
Banks are of the Fort Knox variety; they are more impervious to shelling
than any other sector and militia in them fight twice as hard
against attack as those in industries.
Banks are also particularly adept at moving gold bars around;
bars are moved and stored in groups of four thus fewer mobility units
are required to move a gold bar from a bank than anywhere else.
.s1
.ce
INDUSTRIES
.s1
DEFENSE - In defense plants construction materials are turned into guns.
The conversion of \*Qraw\*U materials into guns
takes place automatically at a rate dependent on
the efficiency of the sector,
the presence of the required materials,
the technology level of the country,
and the number of workers in the sector.
See \*Qinfo Products\*U for information on the materials required to
produce guns.
.s1
SHELL INDUSTRY - These sectors are similar to defense
plant sectors except they turn construction materials into
shells.
The conversion of \*Qraw\*U materials takes place automatically
at a rate dependent on the efficiency of the sector,
the presence of the required materials,
the technology level of the country,
and the number of workers in the sector.
See \*Qinfo Products\*U for information on the materials required.
One shell is used each time you fire,
(except for submarines which use three shells to make one torpedo).
.s1
MINE - Mines produce iron ore by digging it out of the ground.
The rate at which it is produced is dependent on three factors;
the efficiency of the mine,
the number of civilians working in the mine,
and the mineral sample for the sector (\*Qmin\*U on the census report).
Iron is a \*Qrenewable\*U resource; i.e. digging up iron does not
deplete the mineral content of the sector.
.s1
GOLD MINE - Gold mines are similar to ordinary
mines, (above), except that they produce gold dust.
The rate at which it is extracted is dependent on three factors;
the efficiency of the sector,
the size of the labor force in the sector,
and the gold sample for the sector (\*Qgmin\*U on the census report).
The raw gold dust can be transported to any sector but if it is left
in a bank sector it will be refined into bars automatically .
Gold is a non-renewable resource; i.e. extracting the gold depletes
the gold content of the sector.
.s1
URANIUM MINE - Uranium mines are very similar to gold
mines, (above), except that they produce radioactive materials.
The rate at which it is extracted is dependent on three factors;
the efficiency of the sector,
the size of the labor force in the sector,
and the uranium content of the sector
(\*Quran\*U on the census report).
Uranium is a non-renewable resource; i.e. extracting it depletes
the content of the sector.
.s1
HARBOR - Harbors combine shipyard facilities and docks.
Construction materials are converted into ships
and the ships can be loaded and unloaded in the harbor,
(see \*Qinfo load\*U).
No ships are constructed until the \*Qbuild\*U command is given,
(see \*Qinfo build\*U).
.s1
WAREHOUSE - Warehouses are used to store shells,
guns, iron, gold dust, food, oil, light construction materials, and
heavy construction materials.  Moving the above out of a 
warehouse only takes one tenth the mobility cost it normally would.
Note: warehouses are often used as distribution centers.
.s1
AIRFIELD - Airplanes can only be built in airports and most can
only take off and land at airports.  (though some can take off
and land in other sectors and some can take of and land on
aircraft carriers see Ship-types for details) 
.s1
AGRIBUSINESS - These sectors are large farms and provide food.
Agribusiness sectors produce as much as five times as much food
as other sectors.
The harvesting takes place automatically
at a rate dependent on the efficiency of the sector,
the fertility of the sector (\*Qfert\*U in the census),
the technology level of the country,
and the number of workers in the sector.
See \*Qinfo Products\*U for details.
.s1
OIL - Oil fields produce oil by sucking it out of the ground.
The extraction of oil takes place automatically
at a rate dependent on the efficiency of the sector,
the oil content of the sector (\*Qoil\*U on the census report),
the technology level of the country,
and the number of workers in the sector.
Oil is a \*Qnon-renewable\*U resource; i.e. extracting oil
depletes the oil content of the sector.
.s1 
REFINERY - Refineries produce petroleum by processing oil.  
This production takes place automatically
at a rate dependent on the efficiency of the sector,
the number of workers in the sector, 
and  the technology level of the country.
.s1
LIGHT - Light manufacturing plants produce light construction materials
from iron.
This production takes place automatically
at a rate dependent on the efficiency of the sector,
the iron in the sector,
the technology level of the country,
and the number of workers in the sector.
.s1
HEAVY - Heavy manufacturing plants produce heavy construction materials
from iron.
This production takes place automatically
at a rate dependent on the efficiency of the sector,
the iron in the sector,
the technology level of the country,
and the number of workers in the sector.
.s1
.s1
.ce
MILITARY / SCIENTIFIC
.s1
FORTRESS - Fortress sectors have many special characteristics;
you can fire guns from fortresses,
whenever an attack is launched from a fort or on
a fort the militia in the fort are stronger than military
in any other type of sector by an amount proportional to
the efficiency of the fort. (See information below in sector
stats)
Also, forts and commodities in forts are MUCH more resistant
to damage than normal sectors.
.s1
TECHNOLOGY - Technical centers are bastions
of \*Qpure\*U technology research,
which is to say universities with massive defense department grants.
They turn construction materials
into technological advances thereby raising the technology
level of the country (which affects gun ranges, pollution, etc.).
The conversion of \*Qraw\*U materials takes place automatically
at a rate dependent on the efficiency of the sector,
the presence of the required materials,
the education level of the country,
and the number of workers in the sector.
.s1
RESEARCH - The research lab is a bastion of \*Qpure\*U medical research,
which is to say it is a large university
with massive March-of-Dimes funding.
The research lab turns construction materials into medical
discoveries which raise the research level of the country and
help retard the spread of disease, (usually caused by the pollution
from technical centers).
The conversion of \*Qraw\*U materials takes place automatically
at a rate dependent on the efficiency of the sector,
the presence of the required materials,
the education level of the country,
and the number of workers in the sector.
.s1
NUCLEAR - The nuclear lab is a bastion of applied technology,
which is to say it is an immense underground building filled with
evil geniuses playing Adventure on huge computers.
The nuclear lab turns construction materials into nuclear weapons.
No devices are constructed until the \*Qbuild\*U command is given,
(see \*Qinfo build\*U).
.s1
LIBRARY/SCHOOL - The library/school sector is the foundation
of a country's educational structure.
They use up construction materials to produce units of education
which raise the educational
level of the country (which affects the efficiency of research and
technology sectors).
The conversion of \*Qraw\*U materials takes place automatically
at a rate dependent on the efficiency of the sector,
the presence of the required materials,
and the number of workers in the sector.
.s1
ENLISTMENT - The enlistment sector is the boot camp of Empire.
It converts civilians into militia, once the efficiency level
has been raised to 60%.
Unlike the other production sectors,
it uses only militia as a workforce,
and converts civilians in the sector into military.
.s1
HEADQUARTERS - This is where basic militia are converted into units.
Headquarters also give a bonus to reaction radius for units in them,
allowing them to defend better.
.s1
The \*Qshow\*U command can be used to show special things about sector
types. For example:
.EX show sect build
.NF
sector type    cost to des    cost for 1% eff   lcms for 1%    hcms for 1%
f              500            5                 0              1

Infrastructure building - adding 1 point of efficiency costs:
       type          lcms    hcms    mobility    $$$$

defense factor          1       1           1       1
.FI
.s1
Cost to des is the cost to designate the sector type. This is charged when you
give the designate command.  Note that if the BIG_CITY option is
enabled, then 'c' sectors also cost money, lcm's and hcm's to build,
and they can hold 10x as many civs as other sectors.
.s1
You can also build infrastructure into your sectors.  That is how the
mobilty, for both commodities and units, is determined.  You can also
raise the defensive value of your sectors to a maximum amount (which is
shown in the "show sect stats" described below.)
.s1
.EX des 2,0 f
That just cost you $500
.s1.
Cost for 1% efficiency is the $$ cost per point of efficiency built.
Lcms/Hcms for 1% are similar.

.FI
This shows the relative cost to move through the sector types, and the
offensive and defensive values of the sector types. For example, a capital
with a 100% defensive efficiency is twice as good as a park (since the
base value is 1.00.)  All sectors start with a 0% defensive efficiency,
thus they all start with a defense of 1.00.  You can increase the
defensive capability of any sector up to the amount shown by the "max def"
column.

.LV Basic
Some of the ships currently available in Empire are:
.s1
.nf
torpedo-boat	These ships have been misrepresented in Empire. They were
		designed to kill large ships by swarming them and launching
		torpedoes. In fact, they were projected to be so effective
		that the French 'Jeune Ecole' (Young School) of naval officers
		advocated abandoning battleships entirely, saying that they
		would be helpless in the face of the torpedo-boat. In reality,
		the torpedo boat was limited by it's short range, deficient
		sea-keeping ability, and the battleship's quick acquisition of
		numerous light quick-firing guns and machine guns. They were
		effective when used in large numbers, but tended to die a lot.

destroyer	These include three kinds of ships. First is the 1880-1910
		destroyers, originally 'torpedo-boat destroyers', and meant to
		be cheap ships to screen the battleships. Second is the
		1910-1950 version, meant to kill submarines with sonar and
		depth-charges. Lastly is the 1950-1965 destroyer, an all around
		ship, with ASW and ASuW (anti-surface armament). After that,
		they type mostly died out, as it had gotten too large.

frigate		Originally, these were ships of about 200-400t, with a crew
		of 200-500, armed with from 30-50 large cannon plus numerous
		small cannon. They were intended to scout for ships of the
		line, and protect/destroy commerce. After about 1860, the type
		died out entirely, and was replaced by light cruisers. In the
		1960's, the type was resurrected for a new class of ASW (anti
		submarine warfare) ships of small-medium size.

light cruiser	The class came into existence in the 1860-1905 period to provide
		fast ships suitable for extended deployment in far-away places.
		They were intended to out-class local defense boats, and not
		much else. Much was sacrificed to give them long-term speed
		end endurance. They were not intended to have a role in a major
		battle.

heavy cruiser	This class has a dual role. It was intended to reinforce the
		light cruisers in the colonies, providing a heavier punch and
		more armor, and also to be scouting elements in major fleet
		battles.

ship-of-the-line
pre-dreadnought
dreadnought
battleship	While the names change, the purpose remained the same: a ship
		that brings heavy guns close to the enemy and destroys him. It
		also was much used for off-shore bombardment, and for ships
		of the line, minor invasions. (A complement of 300-400 marines
		and 600 sailors allowed a ship of the line to land up to 750
		fighting men at any desired point. Small squadrons of these
		ships could (and did) take over towns, attack fortresses by
		surprise, and generally make life miserable for the defense).
		
		The pre-dreadnought was a battleship with a limited number
		(usually 4) of heavy guns, numerous lighter guns ('secondary'
		and 'tertiary' armament), and heavy armor on vital portions
		of the ship. They were hard to kill, even for themselves, as
		they had only a few guns that could penetrate the armor of
		their peers.

		The dreadnought was introduced in an article in Jane's Fighting
		Ships by an Italian designer, who received permission to publish
		his design after the Italian government decided that it was
		too large and expensive for them. The design/concept was seized
		upon by First Sea Lord Jacky Fisher, who rushed completion of
		the first ship, the Dreadnought, through in only 1 year. (An
		amazing feat and a major record) The Dreadnought gave its
		name to the entire type of ship, having 8-12 large calibre
		guns, few secondary & tertiary weapons, and good armor. (As
		can be guessed, the threat posed by torpedo boats had diminished
		considerably, mostly with the quiet abandonment of the policy
		of close blockade, and the advent of the destroyer)

		The battleship of the 1918-1945 period was faster, and carried
		a new AA capacity, especially in the latter years of the period.
		
		After 1945, the class died out (except for 4 ships)

		For our purposes, a battleship 1 is a ship of the line, a
		battleship 2 is a pre-dreadnought, a battleship 3 is a
		dreadnought, and a battleship 4 is what was called a battleship
		or (sometimes) super-dreadnought.

battlecruiser	These special ships existed in the 1905-1920 period, prior to
		the widespread introduction of oil fuel. They had full battle-
		ship guns, and a large speed advantage over the battleships,
		but very little armor. They were initially the pet project of
		First Sea Lord Jacky Fisher, who intended them to both kill
		the heavy/armored cruisers of the time, and to scout for the
		battleships. With their heavy armament (and name), their
		function inevitably blurred, and they were used in combat
		against full-fledged battleships, where they died like flies.
		With this (and with the introduction of oil fuel, which made
		battleships their equal in speed), they were phased out.

ASW cruiser	These ships came into being in the 1965-present period in 
		response to a need for a large ASW ship to carry ASW helicopters
		and command equipment. It typically carries full ASW armament,
		as well as a minor ASuW capability.

missile boat
missile frigate
missile cruiser	These ships range in size from 100t missile boats (the modern
		replacement for the torpedo-boat) to the 6000-8000t missile
		cruiser. They all are designed to bring missiles to bear on
		the enemy. (The first successful missile boats were Egyptian,
		and used against the Israelis in the 1967 Arab-Israeli war)

		The missile frigate and cruiser also serve as SAM ships.

landing craft	These ships are relatively unique, being used mainly in the
		1942-1950 period. Before that, landings were carried out by 
		frigates, ships-of-the-line, light & heavy cruisers, &
		pre-dreadnoughts, all of which could land a large number of
		men. With the introduction of the concept of beach-defense by
		the Germans, these ships were invented to get large numbers of
		men on the beaches quickly. After 1950, their functions were
		largely assumed by the helicopter.

aircraft carrier
light carrier
escort carrier	These ships are designed for various purposes. At first,
		carriers concentrated on scouting for the battleships. Later,
		it was proved that airplanes could sink battleships (Thanks to
		Billy Mitchell here), and the emphasis moved to all-around sea
		control. Still later, with the disappearance of the battleship,
		a large power-projection capacity was added.

		Light carriers were simply smaller versions of the large or
		'fleet' carriers, and were used for the same duties.

		Escort carriers were usually hastily converted merchantmen,
		and carried small numbers of fighters and ASW planes. (Some
		merchantment, in fact, were equipped with 1 fighter and a
		temporary catapult. When threatened by enemy planes, the
		fighter took off. When it was done, it ditched, and the pilot
		was (theoretically) picked up by the merchant ship's convoy.
		This was used several times, and worked!)

submarine	The submarine was originally intended, in the 1900-1910 period,
		to fill the same role as the torpedo boat, using stealth to
		get to the battleships instead of speed. It was a strictly
		defensive weapon, without much speed or endurance. 

		In the 1910-1925 period, the sub was much enlarged, and use in
		a combination anti-battleship (sank at least 20)/anti-commerce
		role. Endurance was much improved, and the sub could now
		operate a long distance from its home port.

		In the 1925-1945 period, the sub steadily grew large and more
		capable, gaining mostly in speed, sonar ability, and endurance.

		After 1945, nuclear power vastly increased the subs endurance,
		making it effectively infinite. Sonar was also vastly improved,
		and removed the reliance upon the periscope. The subs armament
		was also vastly improved with the addition of the SLM & SLBM.

minesweeper	Usually converted fishing vessels, small, and expendable. They
		found and destroyed mines with a variety of tricks, including
		cables & magnetism.

oiler		These ships represent the whole range of refueling ships.

.NA Spies "How spies work"
.LV Expert
.s1
There is a land unit type "spy".  These can be very valuable land units
to have wandering around the planet...
.s1
Spies are very special land units.  They are able to march into any sector
(owned or unowned) and look about.  Of course, if you are marching in unallied
territory, there is a chance you will get caught.
.s1
If a spy is caught by a friendly or neutral country, the country will get a
message that a spy was spotted in their country.  If the spy is caught
by a hostile or at war nation, the spy gets shot on the spot.  The chance
of getting caught while marching about is inverse to the efficiency of the
spy.  So, at 100%, a spy has a 10% chance of getting caught.  at 10%,
a spy has a 100% chance of getting caught.  Thus, you want efficient spies.
.s1
Spies are also very fragile.  If they are caught in any kind of combat,
shelling, bombing, etc. and take ANY damage at all, they die.
.s1
Spies may also be snuck on shore via ships using the "assault" command.  If
you assault a sector using just spies, they have a 10% chance of making it on
shore without being spotted (no matter what their efficiency).  If spotted,
the same rules apply for how a spy is dealt with.  If you mix spies and mil,
the spies must fight just like normal units.  And, since any damage they take
kills them, this is very risky usage of spies.
.s1
You may locate spies using the "llookout" or the "spy" command.
.s1
Use your imagination on how to eradicate errant spies. ;-)
.s1
Submarines may carry up to two spy units.
.s1
When unloaded from a ship, spies are not given over to the owner of the
sector as other units are.

.s1
The Empire Shell (command interpreter)
expects input in the form:
.EX VERB ARG1 ARG2 ...
VERB is any one of the Empire commands on the \Q*command list\*U
(what you see when you type \*Qlist\*U-- e.g. 
\*Qmap\*U, \*Qmove\*U, \*Qinfo\*U, etc).
.s1
The number of ARGs varies from command to command.
In most cases the ARGs need not be supplied on the command line;
any that are not supplied will be obtained by prompting.
The exception to this rule are those ARGs
that are enclosed in [square brackets]
in the command list.
The presence of these ARGs changes the way the command is carried out.
.s1
Certain basic argument types recur often and are abbreviated in the
following ways.
.s1
.AB
 ::= 'se', 'sh', 'l', or 'p' for sector, ship, land unit, or
plane respectively.  If "sector" is not a possibility, then 's' will
likely suffice for "ship".
.s1
.AB
 ::= either a country number or a country name
.s1
.AB
 ::= any one, (or unambiguous abbreviation), of the list of
commodities found in \*Qinfo Selector\*U:
.AB
 ::= loan number
.AB
 ::= sector coordinates in the form: x,y
.AB
.ne 4
 ::= sector(s) in the form:
.NF +0i
lox:hix,loy:hiy ?cond&cond&...
.FI
\*Qlox\*U, \*Qhix\*U, \*Qloy\*U, \*Qhiy\*U are coordinates bounding
the rectangular area to be considered
.s1
\*Qcond\*U is a condition of the form:
.NF +0i

.FI
 is either a , as above,
a number in the range 0 to 65536,
a sector designation,
(\*Qm\*U for mine, \*Qc\*U for capital, etc), a type of unit
(\*Qfrigate\*U, \*Qcavalry\*U, etc), or a selector found in \*Qinfo
Selector\*U.

.in +\w'#\0\0'u
.L <

Thus \*Qmob=100\*U, \*Qore#0\*U, \*Q7=guns\*U, \*Qciv#mil\*U,
\*Qdes=b\*U are examples of legitimate conditions,
(note lack of embedded spaces),
and
.EX census -3:3,-3:3 ?des=+&gun=5&mil>civ
will list all highways
within 3 of your capital
with exactly 5 guns and more military than civilians.
.sp
Similarly,
.EX deliver f -9:9,-9:9 ?f_del=0
will allow you to set up food delivery
in all the sectors that don't already
have food delivery.
.sp
Note that \*Qhix\*U, \*Qhiy\*U, and \*Q?cond\*U are all optional.
Also, the entire \*Qlox:hix,loy:hiy\*U section may be replaced
by either \*Q#\*U, \*Q#0\*U, \*Q#1\*U, \*Q#2\*U,
or \*Q#3\*U, ... which refer to 
\*Qrealm\*Us which you can define.
(See \*Qinfo realm\*U.)
Note that \*Q#\*U and \*Q#0\*U are equivalent.  Also \*Q*\*U refers to
all sectors, and \*Q@x,y:dist\*U refers to all sectors within dist of x,y.
.AB
 ::= one ship number
.AB
 ::= fleet designation,
which may be a list of ships separated by slashes (`/'),
a fleet letter,
the character tilde (`~') which means all ships not in a specific fleet,
or a rectangular sector area.
.AB
 ::= either a single ship number or a fleet designation.
.sp
Note that  specifications may have an optional ?cond&cond...
argument like that used for  arguments.
For instance:
.EX ship ~ ?des=d&mil>5
will list all destroyers that have more than 5 military
which are not currently in any fleet.
.s1
.in \\n(in
.s1
The output from commands may also be sent to a file or another
process by utilizing these alternate syntaxes:
.s1
.ne 2
.EX VERB ARG1 ... > FILE
which sends the output to the file \*QFILE\*U.
.s1
.ne 2
.EX VERB ARG1 ... >> FILE
which appends the output to the file \*QFILE\*U.
.s1
.ne 2
.EX VERB ARG1 ... >! FILE
which sends the output to the file \*QFILE\*U,
replacing the file it if it already exists.
.s1
.ne 2
.EX VERB ARG ... | PROGRAM [ARGS...]
which send the output of the command to the program \*QPROGRAM\*U
with optional arguments \*QARGS\*U.
This is most useful when \*QPROGRAM\*U is some type of
pager like \*(iFmore\*(pF(1) or \*(iFless\*(pF(1).
.s1
The Empire shell also recognizes a few control characters:
.s1
.in +\w'interrupt\0\0'u

.s1
Civilians exist in Empire to work and provide cash to the government.
Simply by existing,
they generate revenue to their host country
in proportion to the efficiency of the sector
in which they work.
.s1
The military-industrial complex exists
in order to siphon off hard-earned tax dollars.
Military cost (in general) about ten times as much
as a civilian pays in taxes.
.s1
In addition, \*Qfinal goods and services\*U cost money to produce.
Ships, land units, planes, guns and shells are all examples of the costs
inflicted upon a helpless government by the military-industrial complex.
Also, \*Qservices\*U such as technology research, medical research,
and even happiness (money and lcm's can buy happiness here...)
cost something to create.
Consumer items such as food, lcm, hcm, and all other \*Qintermediate
goods\*U (or raw materials) cost nothing other than the hard work of
the oppressed citizenry.
.s1
Note that it takes ten civilians to keep one soldier in the field.
Note also that the only way to make money is either to be pacifistic
and let your nation accumulate wealth by having a small standing army,
or by selling products to other nations. Also, land units can multiply
the strength of each mil, making them perhaps more economical, if you
already have made the technological investment.
.s1
Also note that captured civilians only pay 1/4 the normal taxes.  They
like to hide money until they are all finally agree to become naturalized
citizens of their new government.

.NA Technology "How technology level is calculated each update"
.LV Expert
.s1
Your technology level affects the range that guns can fire,
the range over which radar is effective,
the range that planes can fly
and the range that torpedoes can travel, among other things.
.s1
The \*Qnation\*U command will display your current technology level
and technology factor.
.s1
.nf
This is how your new technology level is determined every update:

(1) Technological breakthroughs are produced in tech centres.
See "info Products" or the "production" command to find out how many
technological breakthroughs you are going to produce.  Your update
telegram will tell you the number of technological breakthroughs
produced in your various tech centres in a line like this:
  technological breakthroughs (7.2) produced in 3,1

(2) Calculate tech delta from technological breakthroughs
In the output of the "version" command, you will see a line like this:
  Tech Buildup is limited to logarithmic growth (base 2.00) after 3.00.

In this example, the "tech log base" is 2.00 and the "easy tech" is
3.00.  To find out what your tech delta for an update will be, subtract
"easy tech" from the number of technological breakthroughs you are
producing and then add 1, then take the logorithm with base "tech log
base" and then add the "easy tech" back on.

For example, say you had a number of tech centres producing a total of
18.0 tech units.  Then to calculate your delta, first subtract "easy
tech" from it and then add 1 to obtain 16.0, then take the log base 2.0
of that which is 4.0 (since 2 to the power 4 is equal to 16), and then
add the "easy tech" back on to get a tech delta of 7.0.

(3) Tech bleed
If the ALL_BLEED option is enabled, then you will gain extra technology from
all countries producing tech, and there will be a line in the
"version" output like this:
  The technology/research boost you get from the world is 50.00%.

If the ALL_BLEED option is turned off, then you will gain extra
technology from the countries with whom you share a two-way alliance,
and the line in the "version" output will look like this:
  The technology/research boost you get from your allies is 50.00%.

In both cases, the amount of tech you get is 50% of the average amount
of tech delta for all eligible "bleeders".  Note that a fundamental
difference between these two cases is that in the ALL_BLEED case, only
countries which are producing tech are counted in the average, whereas
in the case where ALL_BLEED is turned off, the amount of tech bleed is
averaged among all of your allies whether they are producing tech or not.

Your net tech delta will be printed in your update telegram as:
  3.000 technology (2.0000 + 1.0000)
where the 3.0000 is your net tech level gain, and that is broken down into
how much you produced (2.0000) and how much you got from tech bleed (1.0000).

(4) Tech decay
After your net tech increase has been added to your country's
technology level, then your technology level will decay.  The amount of tech
decay is printed in the version output as:
  Nation levels (tech etc.) decline 1% every 96 time units.
The number of time units in an update is printed in the version output as:
  An update consists of 60 empire time units.
Every update, your tech is reduced by
  decay = (tech level) * (decay rate) * (etu per update) / (decay etus).
So if your tech level was 200.0, and the decay rate was as above, then
you would lose:
  decay = 200 * 0.01 * 60 / 96 = 1.25
and so your tech would go down to 198.75 from decay.

(5) Tech leak
If your tech level is much lower than the tech level of the highest
tech country in the world, then every update, there is a chance that
one of their high tech secrets will get leaked into your country.

Take the tech level of the highest tech country in the world and
divide by 5.  Call this the "minimum tech".  If your tech level is
lower than the "minimum tech", then every update, there is a 20%
chance that your tech level will increase by one third of the
difference between your tech level and the minimum tech.

.s1
Because of the unique nature of Empire governments,
(i.e. the decision makers spend most of their time on vacation.
Hmmm, not so unique actually),
and the fact that ideally the Empire \*Qenvironment\*U
will mirror the \*Qreal\*U world,
various heuristics dealing with time have been implemented.
.s1
The first is the Bureaucratic Time Unit (BTU) concept
which keeps track of the potential for doing \*Qwork\*U
possessed by your government.
.s1
The second heuristic, (i.e. hack),
is the Elapsed Time Limit (ETL) which limits the amount of time
that players may be logged on each day.
The ETL is not cumulative and is reset to some particular value,
(often two hours, check the \*Qversion\*U command to be sure),
every night at midnight.
.s1
The ETL and BTU counts are displayed with each command prompt
as follows:
.EX
The first \*Q##\*U is the Elapsed Time today, in minutes.
This number starts at 0 every midnight.
The second \*Q##\*U is the number of BTU's remaining.

.NA Trade-ships "How to use trade ships"
.LV Basic
Trade ships are special ships, with a different function than most Empire
ships. They are in the game only if the TRADESHIPS option is enabled.
.s1
Trade ships simulate internal or external trade. In the real world, countries
make goods that they can make cheaply, ship them somewhere they're expensive,
and sell them, making a profit.
.s1
In the empire version, you make a trade ship, using lots of cm's, and costing
$2500. You then sail it to a harbor somewhere and scuttle it. You then receive
money, with a varying rate of return.
.s1
The trade ship MUST be scuttled in a harbor that is at least 2% efficient to
make money. (In other sectors,
it sinks quietly, like most ships) You may scuttle it in either a harbor you
own, or the harbor of an ally. Pirates who capture a trade ship may also gain
money from it, just as if they were the lawful owner (although the news knows
the difference)
.s1
The return rate is based on the straight-line map distance from the harbor
where the trade ship was built to the harbor where it is scuttled.
.s1
You have to sail it at least 8 sectors to get any money at all. At less than
8 sectors, you get nothing, not even your $1750 back. Nothing, nada, zilch,
zip, nothing. Once you make a trade-ship, you're pretty much committed to
sailing it at least 8 sectors...

Currently, the return rates are:

.NF
		Distance sailed		Return rate
		0-7			NO MONEY
		8-13			2.5% * distance
		14-24			3.5% * distance
		25+			5.0% * distance
.FI
.s1
For example, if you sail the ship 10 sectors from the harbor where it was
built and scuttle it in a harbor there, you would get 125% of the money you
paid for it, or $2188. If you sailed it 15 sectors to a harbor and scuttled it,
you would get 153%, or $2678. 
.s1
Use the \*Qpayoff\*U command to see how much the trade ship would pay
were it scuttled in a harbour at its present location.
.s1
If you scuttle a trade ship in the harbor you do not own, you get a 20% bonus
(applied after the value is multiplied by the return rate above), AND the
person owning the harbor gets 10% of the cash you make as a bonus (the amount
before the +20% bonus is applied)
You still get the full amount, but he makes money as well.
(Peaceful trade enriches BOTH countries more than trading only internally).
For the devious, no, being allied with yourself does not mean you get +20% when
scuttling in your own harbors.
.s1
For example, using the #'s from above, if you sailed 15 sectors, and scuttled
in an allied harbor, you'd get $2188 * 1.2 = $2.6K, and your ally would get
$2188/10 = $218.
.s1
CASH GAINED IS ALSO MULTIPLIED BY THE EFFICIENCY OF THE TRADE SHIP.
So, if you get shot down to 21%, don't expect to get the full amount...
.s1
If you capture a trade ship, you are free to scuttle it in any harbor you can
get it into, receiving full cash calculated normally.
.s1
The cash return is multiplied by the efficiency of the ship, so less efficient
ships produce less money.
.s1
Captured trade ships may be scuttled as if they were yours (although you will
get some bad publicity in the news) Payoff is still based on the distance from
the harbor where the trade ship was built, not the sector in which it was
captured.
.s1
You can also use the "order" command to set up automated trading routes with
trade ships and have them navigate and automatically scuttle themselves when
they reach their destination.  See "info order" for more information on this,
but basically you can do things like this:
.NF
    Step 1) Make a harbor
    Step 2) Get cms distributed/delivered to your harbor each update.
    Step 3) Find a destination harbor to sail to
    Step 4) build tradeships in the harbor each update
    Step 5) load civs and food on the trade ships each update.
    Step 6) order the trade ships to sail and autoscuttle in the dest harbor.
.FI
.s1
You can then just repeat steps 4, 5, and 6 each update, and never worry
about your trade ships again.  Unless someone starts intercepting them,
that is...

.NA Unit-types "Description of the different types of land units"
.LV Basic
Some of the units currently available in Empire are:
.s1
.nf
infantry	The Bloody Infantry. Lotsa guys on foot with guns. They're
		slow, and they carry their supplies in horse-drawn wagons,
		which slows them down even more. Slow. They're also not
		terribly good at scouting. They don't attack very well,
		with a multiplier ranging from 1 to 1.5 or so with better
		tech. However, they really shine on defense, with a multiplier
		from 1.5 to 3.0. If you want to hold a line... use infantry.
		They're fairly resistant to shelling and bombing, with the
		later types of infantry units being better.

cavalry		Empire starts just at the end of the age of cavalry. They're
		quick, and they scout pretty well. They're better at attacking
		than defending. They are pretty easy to kill with shelling or
		bombing. Still, if you want a low-tech unit to go somewhere
		quick, they're the guys.

supply		Supply units range from horse and wagon to truck units. Early
		supply units are slow, but the later supply unit types are
		motorized and are faster. Supply units carry a bunch of stuff,
		but try your best not to get them in combat, because they don't
		enjoy it, and they're REALLY bad at it. Supply units can give
		supplies to land units, as well as forts/ships/sectors. See
		info supply.

lt armor	Armor units may be light, medium, or heavy. Light armor units
armor		have much the same uses as cavalry, although they are a good
hvy armor	bit less fragile. Medium armor is medium-fast, good for general
		attacking, while heavy armor is slow, but good for assaults,
		any situation where you need to destroy a heavily-defended
		fixed point.

		All armor is better at attacking than defending. Higher tech
		types of armor units are better at defending, however. Armor
		gets much of its combat advantage from its mobility, being
		able to attack and move in, severing supply lines & blocking
		reaction & reinforcements.

		Armor is fairly resistant to shelling/bombing.

artillery	Artillery is a long range killer. You can use it to shell
lt artillery	sectors, but it can often be more effective when used as
hvy artillery	support for your attacks. Lt artillery has more mobility,
mech artillery	but less damage. Hvy artillery has less mobility, but more
		damage. Mechanized artillery gives you good damage and good
		mobility, but is very expensive.

		The better the accuracy of the artillery, the better it is
		at assisting your troops or shelling ships. The better the
		damage rating, the better the damage done. High-damage, low
		accuracy artillery is mostly good for shelling sectors, while
		high-accuracy artillery is good at supporting your troops,
		or shooting at ships.

		All artillery is bad at attacking, but can usually defend in
		a not-horrible fashion. Artillery units are, however, pretty
		vulnerable to shelling and bombing. (except for mech artillery)
		
engineers	Engineers are the most versatile unit. They can lay mines,
mech engineers	clear mines, defend well, attack well, work on sectors, etc.
		The drawbacks? Well, they're VERY expensive and not very
		big. Mech engineers have vehicles and are much faster and
		more resistant to damage.

mech infantry	These two types of infantry are faster. Mech infantry is
motor infantry	also more resistant to damage and even better on defense.

marines		These units are like improved infantry, but more expensive and
		harder to make. Their best use is for assaulting beaches, but
		they do make superior infantry if you have to use them that
		way.

security	These units are good at fighting guerrillas, but not for
		much else. They fight about as well as low-tech infantry,
		and their smallish size makes them not worth much.

		They do help you when shooting helpless civs (see info shoot),
		and fight guerrillas during the update. The security troops
		get a chance to 'raid' the guerrillas and kill some of them
		before the guerrillas fight. This will reduce your casualties
		from guerrilla war.

radar units	These units are high-tech. They give you the ability to
		map the enemy easily as you advance. Try not to get them
		into combat, as they're horrible at it, and they're very costly.
		They're generally motorized, so they're pretty fast, and they
		all get shelled/bombed hard.

aa unit		These units are good defensively, and fight planes well. They
		are a mechanized unit, and move & survive pretty well. Only
		units with the FLAK ability can fire AA.

Use the "show" command to see units stats and capabilities.

First, there are no real rules to playing empire.  What you do
is what you do.  There are some general guidelines here, and some
deities may be more forgiving than others.
.s1
One player, one country.
You man NEVER use any country other than your own.
It is ok for two people to play one country
but it is NEVER ok for one person to play two countries.
If you are caught doing this, your countries will be removed
from the game.
In addition, your registrations for future games may be
declined.
DON'T DO IT.
.s1
Ok, but what do I do when I'm away?
.s1
.in +.5i
1) you may turn over your country to someone who has never
played anyone else's country in that game.
You MUST tell the deity if you do this
as he/she/it will be watching who is playing what.
.br
2) you may turn your country over to the deity.
.in -.5i
.s1

What follows is a list of clients which support the new Empire4
protocol.  All of these clients may be found on the Wolfpack Empire
Archives located at:
  http://www.empire.cx
or
  ftp://ftp.empire.cx/pub/empire/

empclient-2.8   - full support

If you are using one of these clients, then you should type
"toggle inform" once you have broken sanctuary.  These clients
are fully asynchronous, which means that they are able to respond
immediately when an unexpected message arrives from the server.  So,
for example, if someone sends you a "flash" message, then the message
will be printed on your screen immediately.  Similarly, with "inform"
toggled on, you will be informed the moment a telegram arrives.  Note,
the server remembers your toggle flags when you log out, so you do not
have to type "toggle inform" again the next time you connect.


other clients   - no support

Most other clients should work fine with the Empire4 server, however
they may get confused if a flash message comes in.  Users of other
clients should keep the "inform" flag toggled off, and ask a friend to
send them a "flash" message to see how the client handles it (note,
you must declare friendly relations towards them in order to receive
the flash message).  If the flash message confuses your client, then I
recommend you type "toggle flash" to turn flash mode off.

In addition, there are a list of commands which have been added to the
server to help the development of clients.  They are:
.NF
   dump - Dump sector information
   ldump - Dump land unit information
   sdump - Dump ship information
   pdump - Dump plane inforamation
   ndump - Dump nuclear stockpile information
   lost - Report lost items
.FI
.s1
See the various info pages on these for complete documentation on how they
work and how you can use them to help improve your clients.
.s1
In addition, there is a "timestamp" field on each object (sectors, ships,
land units, planes, nuclear stockpiles, lost items) that you can use to 
compare against to keep data between clients and the database in sync with
each other.  These timestamps are kept in systems seconds, so they should
be accurate down to 1 second.  Every time an object is changed, it's
timestamp is updated.

\*(iFDefense Against Nuclear Attacks
Through the Denial of Information\*(pF
by Tom Tedrick
.s1
A very good defense against nukes is to make
it as difficult as possible for other players to find out
where your country is, and thus to make maps of it.
.s1
Here are some simple steps that you can follow:
.in +\w'MM)\0\0'u
.s1
.L 1)
Shoot down all planes that fly over your airspace.
It helps to have numerous airfields,
say one airfield for every 25 sectors or so.
Every airfield should be within interception distance
of several other airfields,
so that it is more difficult for an enemy to destroy or capture it.
If an airfield is detected and nuked,
you still have backup airfields.
Every important sector should be within interception distance
of several airfields.
.s1
.L 2)
Seal off all entrances to your inland seas by building
bridges and laying mines
(so no enemy ships can penetrate the area for mapping purposes).
.s1
.L 3)
Sink all surface vessels and submarines near your coastline.
Have large fleets of destroyers posted around exposed coastal areas
covering all sea sectors where enemy subs
might try to sneak in for mapping purposes.
Usually two fleets of 30 destroyers each are enough.
Navigate the whole fleet one sector, stop and look for subs,
navigate one more sector, stop and look for subs, and so on,
until the fleet has made a circle and is back in its starting position.
Sink any subs you find, of course.
.s1
There is a maximum number of around 30 ships that can be in a
fleet if you want to maneuver the whole fleet by fleet name
(see \*Qinfo fleetadd\*U).
.s1
.L 4)
Establish alliances under the condition that secrecy is maintained
with respect to map information.
Thus other allied countries can serve as
a buffer zone against enemy countries.
Many players are willing to be good allies.
.s1
.L 5)
Destroy or capture nearby radar stations.
.s1
.L 6)
Destroy or capture enemy air bases
within range of your country.
Until enemy technology gets high enough
to launch against any target world-wide,
they will often try to get someone to let them have an airbase
hidden near your country and launch nuclear strikes from there.
I've always been able to find these if I worked at it.
.s1
.L 7)
Use psychological warfare.
Nukers get tired of nuking you if it seems to have no effect.
For example, have numerous false capitals, so that when,
after great efforts, they manage to find
what they think is your capital, and nuke it, only to
discover that it was a fake, they will get discouraged.
These fake capitals are also very useful as backups in case your
real capital is discovered and destroyed.
.s1
When an enemy gets close to doing real harm,
a counterattack can often divert attention away from the current attack.
Psychologically, attackers seem to underestimate the harm
they are doing to you if you don't give out any information about how
you are being affected,
and they seem to overestimate the danger to themselves
from your counterattack.
.in
.s1
.ce 3
\*(iFShip Networks and the Art of
Transferring Supplies\*(pF
by Tom Tedrick
.s1
Build large quantities of ships.
When they're 100% efficient,
load them with military and food (and civilians) if possible.
Load guns and shells if you have them,
but since they tend to be scarce, only a few ships will have them.
Navigate them one by one as far as they will go.
Leave only one ship in each sector
(this makes it difficult for an enemy to sink very many of them,
due to mobility restrictions
and the problem of locating and identifying them one by one).
On your maps, mark the ship number in the appropriate sector.
Each sea sector thus has at most one ship number.
.s1
Unless there is something in particular you want to do with
a particular ship, leave it sitting in its sector indefinitely.
.s1
As you build more and more ships,
move them out one by one.
If you leave ship \*(iFX\*(pF
in a sector that already contains ship \*(iFY\*(pF,
ship \*(iFY\*(pF should have full mobility by then.
Navigate ship \*(iFY\*(pF as far as it will go,
then leave it sitting until a new ship comes along.
.s1
Every ship in the network is now likely to be within range of
some other ships in the network.
If a ship requires any supplies,
you can load them on a ship in a harbor,
navigate it out, transfer the cargo via tend,
navigate the tended ship,
transfer its cargo, and so on,
until you reach the any ship in the network.
If you need military for assaulting or boarding,
guns and shells for firing, torpedoing or laying mines,
or if you simply want to move stuff into a distant harbor,
you can do it using several tend and navigate operations.
.s1
This has been particularly useful for sinking subs.
I don't have enough guns and shells
to keep all of my 100 or more destroyers fully armed,
but when one of the unarmed destroyers spots a sub,
I can arrange to transfer guns and shells to it from a loaded
ship (or from a harbor).
.s1
It's a very simple system from the player's standpoint,
because all the player has to do is build the ship,
navigate it, mark its number on the map,
and forget about it until a use for it arises.
As more ships are built,
the network automatically expands without requiring any planning.
You don't have to keep anything in memory,
except the ship number on your map.
If any enemy surface ship gets trapped in the network,
it's quite likely you can capture it,
even if all you have is cargo ships
(battleships, landing craft, and carriers could take some work though).
If an enemy sub is spotted by your destroyers,
you can almost always sink it.
If a convenient target for an assault appears,
you can get the necessary military there.
.s1
.ce 3
\*(iFSome Tricks to Use When Fighting\*(pF
by Various People
(Mostly by Tom)
.s1
The trick for boarding destroyers:
you need a bunch of cargo ships,
both to make several boarding attempts and to tend military.
When you try to board a ship, both the attacker and defender
lose the same amount of mobility.
First you have to get the destroyer's mobility to be negative.
Then you just keep trying to board it from one ship after
another until you win.
That's where my ship network method comes in handy.
I usually have swarms of ships I can surround enemy ships with.
.s1
If I have planes, my normal method is to take a sector I can see,
put enough military to hold it,
designate it \*Qe\*U if it has lots of food,
or maybe something else if there is a reason.
Then get information about the adjacent sectors
and take the most promising one.
Without planes it's more of a struggle.
Anyway, I kind of zig-zag into the country taking the most
interesting sectors, ignoring the others.
This really seems to freak people out,
when an enemy takes a path right through the heartland.
.s1
I would use planes (so having numerous airports
each with a fair supply of fighters, spread around
your country, would be the best countermeasure),
ships (having forts loaded with guns and shells
covering all coastlines helps a lot;
also having destroyers and subs spread around your coastal
waters in order to spot and counterattack enemy
ships, also have bombers to bomb enemy ships, and
radar stations to spot them is useful).
.s1
I would invade by land, firing from forts,
(mainly you need to counterattack actively when the enemy takes any
sectors in your area, also forts with guns and shells help a lot).
I would capture islands and build bridges to get into your country
(so watch all offshore islands with bridge span range).
.s1
Have a lot of shells in warehouses ready to be moved to
the front (you can move four for no mobility cost).
.s1
Bombing enemy ships spotted by radar seems to work pretty
well for the most part.
If he has an aircraft carrier you can torpedo it.
.s1
You never know exactly what may happen,
sometimes you get lucky when you think it's hopeless.
Even if a plan has only a small chance of working,
sometimes it's worth a try,
especially if the enemy has to actively do something to stop it.
.in 0
.s1
You should always have at least two capitals sectors, in case you
lose one.
.s1
Just a tip on empire tactics: mobility is the key
to dealing with many empire problems. Its often the
bottleneck which interferes with various things, and
the decisive advantage that gives victory to the attacker.

				Preface

This guide's intended audience is the beginning player and those players
who have played a game or three and would like to have some insight on some
more subtle aspects of the game.  Some experienced players may find some 
benefit from reading this guide as well.  While you may feel you are an
expert, it is always possible to learn.  Nothing in this guide is intended 
to be difficult to understand, and every effort has been made to make this
guide an easy learning tool.

User's Guide to Empire							 3

				Foreward

It has been over a year now since I first sat down and thought in a serious
way about writing this guide.  It has been a long trip with many interesting
turns and developments.  When I first started, the version of Empire that
this guide has ultimately been written for had not yet been released.  Now,
with this project nearing release I find that yet another new version of
Empire is coming out.  I look on in near despair as I realize that this guide
may very well soon be outdated.  Nevertheless, I feel compelled to release
this information in what might be considered a final form.  

However, I hope that this is not the final form.  With new versions of
Empire coming out in the very near future I hope that some other potential
author steps forward and takes up the banner of educating the new player. 
I caution you though that such a work as this takes quite an effort. 

To the reader and any critics or even cynics that might be reading, I say
that I am not writer.  I never was, and I never intend to be.  There are
certainly enough writers in the world to write almost everything the world
could want to know about in print.  I was never skilled in the art of proper
style for any sort of writing.  Please, be kind and keep this in mind.

I wrote this guide because I felt there was a great need for something of
this nature.  I have watched so many players come to the network looking
for information on Empire, such as the rules, or information on how to play.
One can get information about the various commands available to oneself
within the game, but to understand how to use those commands effectively
and get skilled at running a country is a far greater task.  Many new
players have despaired after playing their first game for lack of the
requisite knowledge to play effectively.  Some come back fighting hard
in the next game, but many just disappear never to be heard from again.
This guide was written with the hope that if the new player is supplied
with the basics, they can advance in skill more quickly than previously
possible and not despair at their first defeat. 

I am hoping that within the near future two other companion guides to 
this one will be written and released to the net.  These two guides will
be intended to make the average player a better player or even expert,
and to teach fledgling deities how to compile and establish a, solicit 
entries for , and effectively run, a game.  Some people have commented
to me that the time spent on these guides would be better spent if I 
were to spend time programming for Empire instead.  It is my belief that
in teaching players to be better players, and teaching deities how to be 
a deity should that guide be released, the potential pool for
programmers of Empire will increase.  

I can not take credit for the idea of this guide.  The need for such
a guide I think was painfully obvious to a great many players.  Some in
fact did engage in projects to fill that need.  Every such attempt has
fallen short, in my humble opinion.  Witness the large number of people


User's Guide to Empire							 4

who still ask the network, "How do I play?" and even more importantly
the lack of sufficient answer to such people's questions.  In my highest
hopes, I dream that someday soon that answer will be "Get a copy of the
User's Guide to Empire, which is available via FTP from xx.xx.xx".

This work was made possible by the contributions of several Empire players.
This work would not have been completed without the insights and assistance 
of many Empire players and deities.  To the Empire community as a whole,
I say thank you for your priceless contributions.

Chapter 1 :-: What is Empire?

	Empire is a game in which you are pitted against several other
	players in a country vs. country format.  There are economies to
	run, armies to support, policies to generate, and allies and
	enemies to make.  The game supports various features that make
	certain aspects of the game seem to parallel the "realistic"
	world.  These include satellites, planes, banks, parks, etc.
	
	Empire, in the version herein described, is a very complex 
	game.  The closest game that most people will know that is 
	analogous to it is the game known as Risk.  However, Empire is 
	more complex by a factor of at least one hundred.  Nevertheless, 
	as a result of the computer aiding you every step of the way, the 
	game is not difficult to play, though it can be difficult to 
	learn.  If you read this guide thoroughly, and use it as a 
	continuing resource, you can help make learning this game a lot 
	easier. 

	It should be noted that in learning to play this game, you
	may become frustrated or feel daunted by its complexity. 
	Several players have noted that they almost gave up on Empire,
	until one day when everything seemed to start to make sense.
	I call it the "threshold level of understanding" after which
	learning the art of Empire becomes several grades easier, and
	players learn substantially faster.  I urge you to stay with
	it until you get to that level.  It may take some time, but it
	is well worth the effort.  This guide is intended to get you
	to that threshold level of understanding.

	Games usually take two to three months depending on various factors 
	that are changeable by the person who runs the game prior to its 
	inception.  Some games, known as blitz games, last a day or three 
	and will wear out your finger tips from typing too much, will cause 
	your family and loved ones to be tremendously upset with you for 
	missing breakfast, lunch and dinner for three days straight, will cause
	your stomach to argue constantly with you about its right to
	food, and are a tremendous amount of fun.  Blitz games are not
	for the light of heart nor are they meant for the beginner. 
		
	For more information concerning the basic scope of Empire,
	refer to the game itself.  Within the game, there are 
	various help entries accessible through the command 'info'.
	This guide is intended to go well beyond the scope of help
	available from 'info'.

	Empire, the game, has evolved through many different forms
	over the last decade.  There are still numerous versions
	for various computers around.  The version herein discussed
	is BSD Empire, written for the most part by Dave Pare along
	with a lot of help from net people.  As release time approaches
	I am aware that Mr. Pare is working on BSD Empire V2.0. 
	This guide is only current to version V1.1.5 of BSD.  I wish

	the future author of the guide to V2.0, whomever that might be,
	the best of luck and bequeath that person a family size bottle
	of aspirin for personal use. 

Summary: Empire is a very complex game that has a rather steep learning
	 curve.  Most of the complexity of the game can be handled by
	 the commands available to you, the game server itself, or tools
	 that you use to better your country.  Tools are described later
	 in this text.

Chapter 2 :-: How to get into a game of Empire.

	The most common way of finding about about games that are about to 
	happen is by monitoring the newsgroup rec.games.empire on your local
	news reading program. Other ways are via e-mail by getting to know 
	several players with whom you correspond over the network.  Some 
	games are by invitation only but these are few and far between as 
	usually a game is better with more people in it.  If you do not know
	how to use your local news reading program, ask a local site consultant
	or find a brochure about the news programs available.  One of the most
	common newsreaders can be reached by typing 'rn' from your unix
	prompt.  If you have VMS for an operating system this may not be true.
	To go directly to the rec.games.empire newsgroup you could type in
	'rn rec.games.empire'.  

	Before entering a game of Empire, consider the amount of time that
	you have available to play the game.  Two hours a day for a four
	update per day game is usually the norm.  If you are inexperienced,
	and have not fought in wars before, that two hours will dramatically
	increase should war break out between you and another country.

	Note that it is easy to get addicted to the game.  The player should
	be aware of this prior to playing.  Play in moderation.  This is 
	obviously not meant to scare you off.  It is merely a word of caution 
	to some people.  Remember to play in moderation.

	If you do decide to join in an upcoming game of Empire, then you will
	have the pleasure of playing one of the best games around.  Empire has
	been described as being the most complicated game ever created.
	Despite the fact that the game was created for computers and has
	been in existence for several years, as yet no robot player has been
	developed nor is it anticipated.  It is possible to build such a 
	robot, but it would be a huge task.  Do not be dismayed though.
	Most of the complexity of Empire is handled by the server and client.
	There is a fair amount of what is called "micro-managing" that may
	need to be done to be a highly successful nation. However, it is
	not a necessary thing to do.  Furthermore, there are many tools 
	(described later) that can handle the micromanaging aspects to
	a great degree. 

	After you find out about a game, and decide that you do want to 
	play in that upcoming game, you need to contact the "Deity".  The
	"Deity" is the person who runs the game.  You should mail him/her
	with information about yourself and your country.  A customary 
	basic form for registering your country to play might contain
	the following information:

	Country name: (any name you like, from Brianville to USofA)
	Rep: (this is your *password*)
	Net address: (the address at which you can be contacted over the net)
	Skill level: (1-10..10 being the best, 1 being beginner)
	
	It might be necessary depending on the Deity to include all addresses


User's Guide to Empire							 9
	
	from which you might be playing.  With the proliferation of suns as
	general user machines this is becoming more and more a chore, and 
	few deities require it.  It might suffice to say "mickey@*.buffalo.edu"
	which might cover all machines you play from if you played from
	SUNY-Buffalo.  Mickey, of course, is just an arbitrary username chosen
	for this example.

	Empire players connect to games in progress through a program known
	as a "client".  This program handles communication between your
	computer and the computer that the game is running on. 

	There are several versions of clients available.  Some are more
	"capable" than others in that they can make decisions easier for 
	you or make the decisions themselves.  They are intended to reduce
	the amount of work you have to do to maintain your country though
	in some cases they actually increase the amount of work you have
	to do.  I have listed places from which you can get other types
	of clients from in the FTP listings in appendix C.

	Sources for basic client program is available by FTPing to 
	ucbvax.berkeley.edu.  For the user's benefit, I have included
	a copy of a session in which a user FTPs to ucbvax, retrieves the
	source, compiles the source and establishes the appropriate
	environment variables to connect to a game.  

	Note that the following example will work ONLY on a unix,
	ultrix, or other flavor of unix operating system.  This will
	not work for the VMS client.

This is the empire client for BSD Empire.

To make the program, edit globals.c and change localhost to
point at the machine where the game is running.

Type "make".

You can change hosts on-the-fly by using environment variables -- see
the man page for details.

[** Simple enough.  I don't bother modifying globals.c since I can modify
    the environment variables using the unix command 'setenv'.  So now,

------------------------------------------------------------------


	Since you are playing across a network of computers, it is possible
	that there will be problems along the way in connecting to the server
	from the computer you play on.  What follows are some common connection
	errors.

Problem 1:
autarch{client}!>empire
connect: Connection refused

Problem	  This generally means that you have either set your environment
	  variables wrong (see 'setenv' from earlier in this chapter), or
	  the server at the host site is not currently running.
Solution  (1) Check your environment variables by issuing a 'setenv' command.


User's Guide to Empire							 13
	
	  (2) Wait for the server to come up.

Problem 2:
autarch{client}!>empire
connect: Connection timed out

Problem   This generally means that there is a network outage somewhere
	  along the network.  
Solution  (1) You can monitor the network by using two unix commands located in
	  /usr/etc on most unix systems.  These are 'ping' and 'traceroute'.
	  /usr/etc/ping 128.205.7.3 for instance will send a ping at the
	  host with ip address 128.205.7.3.  If that machine can be reached
	  from your machine across the network it will return:
	  128.205.7.3 is alive
	  traceroute 128.205.7.3 will request responses from each site along
	  the way.  This is useful for seeing which site along the way is 
	  causing the outage. 
	  (2) This solution is easier, but more frustrating.  Wait. 

Problem 3:
autarch{client}!>empire
Country name? 
Your name? 

        -=O=-
3 country in use by mickey@lictor.acsu.buffalo.edu (pid=5797)

Problem	  This one is potentially nasty.  It means that another process is
	  logged into your country.  This could be from multiple sources.
	  1: Your friend who is playing your country as well.
	  2: A process of yours that got accidentally hung.
	  3: The network hung your remote process even though your local
	     process is now terminated. 
Solution  (1) Go kick your friend in the head :-)
	  (2) Kill your process 'nicely'.  To find the process execute a 
	  'ps -x' command and find the appropriate process number:
	  autarch{client}ps -x
	    PID TT STAT   TIME COMMAND
	  3555 t1 S      0:00 -usr/new/csh (csh)
	  3575 t1 R      0:00 ps -x
	  3559 ?  S      0:00 -usr/new/csh (csh)
	  3560 ?  S      0:00 (empire)
	  The offending process number in this list is 3560.  To kill it,
	  simply type the command 'kill 3560'.  After that, all should be
	  well.  Try entering the game again. 
	  (3) If your process is hung on the server machine, you can
	  do one of two things.  First, you can mail the Deity with the
	  "pid", or process identification number.  This number is listed
	  in the original error message and in our case is 5797.  Secondly,
	  you can log in to the remote site and kill the process yourself
	  via the process illustrated below.  Note that in the first line
	  of the illustrated process that the name storm.tamu.edu is the
	  host site for the particular game I am using for this example. 


User's Guide to Empire							 14
	
	  Also, 1617 is the port on that machine that Empire is being run
	  through.  Commands that you should type in are indicated 
	  by a "<----" at the end of the line.

-------------------------------------------------------------------------------

-------------------------------------------------------------------------------

	  Your process is now unhung, and your country should be ready to play
	  once again. 

Problem 4:
autarch{myclient}empire
Country name? 
Your name? 

Bad password

Problem   The server does not accept the password you typed as being correct.
Solution  Try typing it again.  Try using capital letters at the beginning of
	  the password as well, or the entire password in caps.  If this does
	  not work, mail the Deity and inform him or her of the problem
	  and what the password should be.

Problem 5:
autarch{myclient}empire
Alarm clock

Problem   Your connection to the server is not responding.  
Solution  The delay time for waiting for a response that is built into 
	  the client is not exceedingly long.  The theory behind this being
	  that if it is taking you that long to get a response from the 
	  Empire server then it is not worth playing, since response times


User's Guide to Empire							 15
	
	  for information from the game are going to be pretty unbearable. 
	  Keep trying is probably the best solution. 


	These are most of the problems that you will encounter in connecting to
	the game server.  There are some more problems that you might 
	encounter, but generally they are not common.  If you can not reach 
	your game server for more than a day, contact your deity and let 
	him/her know that you can not connect.  

Summary: Getting into a game of Empire is not terribly difficult. Setting up
	 a client program should be a fairly painless task.  If it is not,
	 do not be dismayed.  Get help from a consultant or another player
	 if you can.  Some problems with the network may temporarily prevent 
	 you from playing.  Be patient, the network is a horse that should 
	 be shot, but generally it comes around after a while.

Chapter 3 :-: The primitive basics.


	There are a few basic commands and ideas that will help you get 
	acquainted with Empire.  These are here summarized.

Concept: Sanctuary. 
	All players begin a game of Empire in what is known as a sanctuary.
While you are in a sanctuary state you can not be attacked, overrun, or 
otherwise hurt.  However, while you are in sanctuary you can not do
very many things.  In order to really begin playing the game you need
to do what is known as "break sanctuary".  You can do this using the 
'break' command.  When you do this, your two sanctuary sectors (which
everyone starts with) will become capital sectors.  You are no longer
protected from attacks from enemy countries. 

Concept: Movement in Empire.
	Paths of movement are indicated by several keys.  Path indicators
exist in a hex shape around the letter H on your keyboard.  Thus, y means
travel North-West, u for North-East, j for East, n for South-East, b for
South-West, and g for West.  Also, h means "stop" which terminates movement
of whatever you are moving.  There is one other key, v which "views" the
sector you are currently moving through.  Thus if I gave a movement path
of gggvgh the game would move whatever I am moving three sectors West, view
the sector at three sectors west of my starting point, then move one more 
sector west and then stop. 

Concept: Update
	Empire games have "turns" known as updates.  When an update occurs,
your country goes through economic growth or decline, interests are paid
on gold bars, military costs are paid for, mobility increases in your
sectors, etc.  You can do a great many things between updates, an update
merely does book keeping more or less, at a predetermined time.  To find
out when the next update is going to happen, you can type 'update' as
a command.

Command: map -10:10,-7:7
	This command will give you a map of the area immediately surrounding
your beginning two sectors.  Specifically, it will give you a map from ten
sectors West of your 0,0 to ten sectors East and from seven sectors North to
seven sectors South of your 0,0.

Command: explore civ 0,0 1
	This command allows you to move one civilian from your 0,0 and 
"explore" into wilderness and mountain sectors.  

Command: info commands
	This command will list the various commands available in Empire.
It is a very good idea to go through the information on each command
by typing 'info '.  This will help you get more acquainted
with the game.  Though this guide shows many commands and how to use them,
it is no substitute for the game's help itself. 


User's Guide to Empire							 17

Command: designate 1,1 +
	This command will enable you to designate a sector you own into 
whatever you desire.  Usually, in the beginning of the game you will designate
sectors that you will not be using actively for a while into highways.
The above shown example of the command will designate your 1,1 sector into
a highway.  

Command: telegram 
	Countries in Empire communicate with each other via telegrams.
These are private letters sent just like a telegram would be.  They have
a size limit, but there is usually more than enough room to say what you
want to say.  There is no limit to the number of telegrams you may send.

Command: announce
	Countries broadcast to the world via the command 'announce'.  These
announcements are similar to telegrams except instead of one country reading
the telegram the entire world can read it. 

Command: read 
	This command allows you to read any incoming telegrams or
announcements.  Empire will notify you when you have new incoming traffic.

Command: news {x number of days}
	This command will allow you to peruse the Empire newspaper.  It does
not make for great reading.  However, it is useful for intelligence gathering.
If you just enter 'news' as a command, it will print all the news since you
last read the news.  Entering 'news 3' will give you the news for the last
three days.  In big games, the news file gets quite large.

Summary: These are the basic ideas and commands of Empire.  Empire has a great
	 many commands however, and the player should endeavor to learn them.
	 Empire can be played with only a few commands but the additional 
	 commands are there for your best interests.  If you do not understand
	 a command shown here, simply type 'info ' while in the 
	 game itself.

Chapter 4 :-: Geography in Empire.

	Maps in Empire are based on a simple hex design.  For example:

---------------------------------- There are three basic sector types in
				   Empire (note: "type" is different than
     / \   / \   / \   / \   / \   "designation".  Designation refers to what
    /   \ /   \ /   \ /   \ /   \  that sector has on it, a factory or school
-4 |  .  |  ^  |  -  |  ^  |  .  | for example.  Type refers to what it is 
    \   / \   / \   / \   / \   /  built on).  There are:
     \ /   \ /   \ /   \ /   \ /   seas	: .
-3    |  -  |  -  |  .  |  .  |    mountains	: ^
     / \   / \   / \   / \   / \   wilderness  : -
    /   \ /   \ /   \ /   \ /   \  When using the Empire map, you use an "X,Y"
-2 |  .  |  -  |  -  |  -  |  .  | system.  The X coordinate refers to how far
    \   / \   / \   / \   / \   /  along the horizontal you are, the Y referring
     \ /   \ /   \ /   \ /   \ /   to the vertical.  Thus, there are seas on 
-1    |  -  |  -  |  .  |  .  |    example map at  5,-1  7,-1  0,-2  8,-2
     / \   / \   / \   / \   / \   5,-3  7,-3  0,-4  and 8,-4.  Negative X is
    /   \ /   \ /   \ /   \ /   \  to the left (to the East) of 0,0 just as 
      0  1  2  3  4  5  6  7  8    in your high school math courses.  However,
				   negative Y is above (to the North of) 0,0.
	     Figure 3		   This is different from high school math. 
     Example of an Empire map      Why the maps have coordinates in this way
				   is one of the great mysteries of Empire.
----------------------------------  
				    
	Figure 4 below is a real map of Empire, in its real size and form.

-------------------------------------------------------------------------------

	As you can see, there are a wide variety of sector types in Empire.
	However, until your country becomes populated the most useful sector 
	is the highway ('+'), for it allows you to move things around easier, 
	even if the highway has only begun being constructed 
	(ie, 0% efficient). 

Summary: Empire maps are based on a simple hex design, with the movement
	 keys based similarly around the letter h on standard keyboards. 
	 These movement keys are a basic tool in Empire and must be learned.

Chapter 5 :-: The beginning phases of Empire.


	Typically a game starts with a `speed' phase. If it does not, then
	initial play can get boring quickly.  A `speed' opening also demands
	more time for the period when the updates are frequent, but hopefully,
	that will be balanced by your efficient country and the less time
	spent running it when your classes/real life demand more time. 

	There are several opening strategies for Empire players.  I am going
	to go through a few of them here.  If you feel you can make a better
	strategy feel free to do so. 

	Basically, all strategies for the opening phases revolve around a 
	few basic ideas.  First, you want to secure as much land for yourself
	as possible.  Secondly, if you share an island with some other person,
	you want to leave yourself in a strategically advantageous position
	against your opponent, optimally to surround him/her before s/he breaks
	sanctuary.  These two ideas are the most important things to consider 
	prior to the first update.  There are other things to consider, which 
	will be reviewed later.

	It is highly important for you, the player, to begin playing the game
	as soon as the game begins.  If you do not, you risk being surrounded
	before the first update.  Furthermore, not breaking sanctuary prior to
	the first update can cost you a great deal in terms of population 
	growth and the establishment of your economy.

	Some players will use tools, which are reviewed in chapter 14, to 
	break sanctuary and occupy land from the beginning.  There are other 
	means to aid your land occupation as well.  If you have a programmable 
	terminal, or terminal program, you can program a key to contain a 
	particular command such as "explore civ 0,0 1 jjjujuuu".  This could 
	be a path along a line of land that you have already occupied, and 
	wish to expand beyond.  If you had to repeatedly type in that command 
	and path you would take a much greater amount of time to occupy land.
	This can also be done through X windows, using the mouse and cut/paste
	capabilities. 

	There are a few different theories on how to explore out from your
	sanctuaries to claim as much land as possible for yourself. 

	In the following maps, the square island shown is entirely wilderness
	except for the two sanctuaries in the middle.  It is important to note
	that prior to exploring the entire island, the only thing you would 
	be able to see on your map would be this:

	 - - - s s - - -
	  - - - - - - - 
	   - - - - - -

	It is your job to explore the island, while occupying, or securing for 
	yourself, as much land as possible.  Note that for the sake of 
	simplicity I have not placed another country on this example island.  
	If a sector is a "+","c", or "s" it is an occupied (by you) sector.  
	If it's a "-" it's a wilderness sector, and if you can move into it, 
	it is unoccupied.  This is an important piece of information.  If you 
	can note move into a wilderness sector it means that it is occupied by 
	another country.  Note that "." are seas, as indicated in chapter 5.
	The basic commands to complete this exploration are 'explore' and 
	'designate'.  Learn about those commands either from chapter 4 or 
	the game before attempting these theories. 

	First, I show the entire island prior to your breaking sanctuary and
	exploring:

	Next, I show theory 1, occupying in a concentric circle. 
	Note that once you have broken sanctuary (using the 'break'
	command) that your two sanctuary sectors immediately become
	capitals, with your real capital at 0,0.

	Now, 84 sectors have once again been occupied.  However, an additional
	56 sectors are now within the borders of your country.  Thus, securing
	a total of 140 sectors for yourself.  The disadvantage?  You have three
	lines of occupation ( the "+" sectors) between the center of your 
	country and unsecured wilderness.  In theory 1, the same number of 
	sectors provides for 4 lines for most of the country.  Another 
	disadvantage is that it costs more mobility to use theory 2.  The more
	lines of occupation you have between the central areas of your 
	country and the unexplored wilderness or an enemy the easier it is
	to defend your country. 

	A third theory is the idea of coastal occupation as a means of securing
	a large island.  The idea being to secure the land immediately around
	you and then explore in one direction until you find seas, and then
	proceed to occupy the coast:

--------------------------------------------------------------------------------

	Here, once again, 84 sectors have been occupied.  In addition, 179 
	sectors of wilderness have been secured, ie cut off from another 
	country.  This brings a total of 263 sectors occupied or secured.  
	This is obviously impressive.  However, it has its drawbacks as well.
	If there was a country bordering this country, that country would 
	need only to attack and occupy one of your sectors and then they 
	could explore into all of the "secured" sectors.  In addition, there 
	are only 2-3 lines of occupied sectors between the borders and the 
	center of the country.  This also costs more in terms of mobility than
	either theory 1 or 2. 

	The next section contains a strategy submitted by Scott Yelich.  Scott
	adheres in this summary to theory 1 as his method of exploration:


User's Guide to Empire							 25


  "Designate one of the two initial [sanctuary] capital sectors to
an agricultural center.  Then move a civ out from either sector to
either 1,-1 or 1,1 and designate it a +.  Then, I continue to move out
one civilian at a time from both of my initial sectors.  Only move
the civ one spot into the wilderness and then I designate that sector
as a highway (+).  Then, do a map to see if there is anything
especially interesting... such as, a mountain, more land or ANOTHER
PLAYER.  Of course, Only do that map at certain times... it's not
necessary to do a map after EVERY explore since explore will show you
a one sector radius!

[Editor's note: exploring with one civilian across a wilderness sector
takes .8 mobility.  Across a highway, even a 0% highway, it will cost
only .2 mobility.  Thus, the reason for designating new land as soon
as you occupy it.  You will conserve mobility if you only explore into
lands bordering your new highways.]

  "Here is where quick action comes into play.  If you spot any controlled
sectors (?) or a (-) that can't be entered (if you can note move into the
sector it is occupied by someone else! hurry!), try to make a boarder as
quick as possible by following the pattern above... move one civ, look,
repeat.  If you don't find any controlled sectors, simply [try] to
AVOID MOUNTAINS at ALL costs...  especially during the first couple of
updates.  Typically, from 30 to 70 sectors can be grabbed this way
within the first minute or two.

  "To sum up, the strategy for this is: 1) You want to see who is out there, 
2) You want to see what land is out there, 3) when you take more sectors 
during the initial updates, you will get more mobility each update 
(typically 8, 'version' will tell...).  Anyway, the more sectors you grab 
with the first update, the more you can grab the second.  It's like an 
exponential function."


	This next section is a strategy submitted by Geoff Cashman.  Geoff 
	adheres in this summary to theory 2 as his method for exploration:

  "The basic strategy of moving one sector into the wilderness and then 
designate them with a command such as this:  designate #1 ?des=- +  which will 
designate all sectors in realm #1 that are wilderness into highways, is a 
common one.  Using it wisely is not always done.  My personal method is to 
expand only in a few directions, ie 3-6 different directions from your 0,0 2,0 
area.  The idea here being to make "spokes" of exploration radiating out from 
your 0,0 and 2,0 area.  Using this method, you can use less mobility and see 
more land though not actually own more land until after the first update.  
Another advantage is you might reach an opponent before s/he reaches you.  A 
weakness is that an opponent can explore inbetween your spokes.  If I feel 
this is possible inbetween two spokes then I connect the spokes via concentric 
(on 2,0 0,0 ) arc several sectors out from the 0,0.  If you do not use this 
method, then you would use up all of your mobility to achieve the same number 
of sectors by the second update.



User's Guide to Empire							 26

  "Why save mobility?  Mobility in the 0,0 sector is especially critical.
The reason is because the 0,0 starts out with 999 civs.  If a sector has
999 or more civs it will not give birth to more civilians.  Half of the
battle in winning Empire is population explosion at the beginning of the
game...ESPECIALLY if you get involved in a low tech war with a neighbor
early on.  More population means more resources mined, more supportable
military, and more taxpayers.  If you are going to be a tech producer then
it may be desireable to limit population, but early on I do not recommend
it.  So, with 999 civs in your 0,0 sector you need to be able to move out
many civs (depends on the number of ETUs per update (see the version command)
as to how many you should move out, see number of births per 1,000 civs per
etu in the version command).  Thus, my strategy is slightly different. 
I concentrate on getting a 100% highway built at 1,-1 or 1,1.  Why those
sectors?  because I can then use the mobility in 1,-1 or 1,1 to move civs
or products into 2,0."


	The use of the third theory requires a player with some experience 
	to deal with its shortcomings.  For the beginner, I do not recommend
	it. 

	The following was submitted by another player to point out their means
	of establishing their production and the beginning stages of their 
	economy:

"Setting up a distribution network, even with inefficient warehouses, is
fairly critical early on.  If you starve civilians in the beginning of the
game, you will fall behind in production.  It is not uncommon to lose 
contact with the game for a day or more due to net failures.  Do not 
depend on your capability to connect to the game to feed your civilians.

"Some people never leave their 0,0 or 2,0 designated as a capital during the 
beginning of the game.  They check the resources in 0,0 and then determine if 
it's suitable for being a mine or a gold mine.  If neither, then they designate
2,0 into a mine.  If mine, then 2,0 becomes a gold mine.  Using this method
they can get maximum production from their civilians that are essentially 
trapped for the time being in their 0,0 and 2,0 sectors due to lack of 
mobility.  Note that in doing this that you must conserve BTUs.  Having
a 0% efficient capital somewhere else will cause a lack of production of
BTUs.  You must be careful not to run out of BTUs completely, or it could
cause you a great deal of grief. 


"NOTE: IT IS EXTREMELY DANGEROUS TO LEAVE A CAPITAL ON THE COAST AFTER
ANYONE PRODUCES A BOAT.  Until that time, a capital on the coast is
an advantage in some ways.  It is easier to defend (less places that
it can be attacked from).  You MUST get some civilians into the capital
at -2,0 (about 50) before the first update along with some food.  
In general, your capital will not produce BTUs for a while, but neither
do you need them for a while.  However, leave your 0,0 sector as your
capital until JUST prior (like 2-4 minutes, make it 10 to be safe) to
the update.  Does this all sound complicated?  Yep.  But it works. 



User's Guide to Empire							 27


"After the first or second update I will occupy the remaining wilderness
that I can see, using the mobility from the sectors that I explored into
in the previous update.   I will then continue to move civs out of 0,0 and
into 1,-1 or 1,1 (the highway that I am trying to make 100%) and move from
there.  If I am not going for tech production then I don't need the library
or parks (you can still make education, it helps in some regards, but for
the most part you don't need it if you are not going the way of tech.

You can then pretty much do as you please and work towards the goals you
think are reasonable for your country.  "

	One matter that can not be overlooked by any player is the simple
	fact that people need food to survive.  If a sector has less than
	60 people in it total, including civs, soldiers, and uws, then it
	will not starve.  But if after the update it has more than 60 total
	people will starve.  Make sure to feed your people!

	Ultimately, you want to take over every sector on your island.
	If you have neighbors on your island, you will probably have to share.
	Just try to get a bigger portion of it than your neighbors do.

Summary: There are several basic ideas expressed in this chapter:
	 1) Break sanctuary as soon as the game begins. 
	 2) Secure as much land for yourself as possible.
	 3) Use your civilians efficiently.
	 4) Do not allow your 0,0 sector to have a lot of civs in it.
	 5) Get a distribution system set up early (explained later).

Chapter 6 :-: Diplomacy.

	It's your own ruin or success.  One of the best players of the game
	(who shall go un-named) has had severe problems due to lack of skill 
	in diplomacy.  Remember, there is another person on the other end of 
	that telegram.  They are human like you are, and like to be treated 
	like it for the most part.  There are jerks, and there are non-jerks.  
	Determine for yourself and go along with what you think is best, but 
	remember, it is ok to lose a few battles so long as you win the war.  
	A diplomatic loss can be an overall victory.  

	One of the most powerful weapons in the game is information. 
	What types of information can you use to your benefit?  Information on;
	the locality of other countries, the plans of opponents, the trading 
	going on between certain countries, etc.  There is also a very powerful
	tool right here in this document: how to play the game well.  There 
	was a classic case of a country (myself) who accidentally announced 
	his attention to attack a bordering country.  The bordering country 
	happened to be on, an began an attack.  The attack stalemated for the 
	most part because of the obvious inexperience of the person running 
	that country.  I offered information to him on how to play the game 
	better in exchange for his surrender and some other terms of agreement.
	I turned a horrendous diplomatic mistake into a diplomatic success 
	within two hours.  This is obviously the rare case (surprised me too), 
	but is a good example of the power of information.

	Another aspect of diplomacy is style.  You project a style in your
	telegrams and announcements whether it is intentional or not.  If 
	people like you they tend to side with you more than the next guy.  
	Of course, if you are a jerk but a powerful one people tend to 
	reluctantly side with you.  Then again, they are more likely to 
	backstab you. 

	While I am on that subject:  Backstabbing is a bad idea in general.
	It leads to distrust of many players with regards to yourself and tends
	to give yourself backstabbist's wrist if you do it too much.  Even if 
	you change your country name from game to game people tend to pick 
	out who the major jerks are and their previous names or even net 
	addresses.  Trust is important.  If you have allies you can trust 
	implicitly you will sleep a lot better at night and also have people 
	who you can trust to run your country for you while you are away for a 
	few days pursuing real world goals.  If you are going to backstab 
	someone crush them while you can and make sure their allies can not
	get at you.  Furthermore, make the world see that the person was a 
	fool for trusting you in the first place (like, due to previous war 
	or some such).  Sometimes, that extra attack you get without 
	interference from automatic defenses due to a declaration of alliance 
	with your opponent can be critical.  You can also map an opponent 
	country if you are allied with them and they will never know it.  
	Thus another good reason why you should be trustable and can trust 
	other close allies.  Having allies is important, especially 
	in the current market games.

A)  What is diplomacy? 
	The dictionary defines diplomacy as "1: The art and practice of 
	conducting negotiations between nations.  2: Skill in handling
	affairs without arousing hostility."  The second definition may
	not be entirely accurate in that in Empire, diplomacy can sometimes
	be used to cause battles, rather than avoid them, to gain a particular
	end.  I will go into this later.  

B)  What purpose, diplomacy?
	Since Empire is a multi-user game the diplomacy side of the game
	is one of the main factors inherent to its playing.  Being able
	to interact with other players, make bargains, treaties, alliances,
	sales, war, etc. leads to an incredibly variety of possible
	scenarios among various countries.  In asking, what purpose is
	there to diplomacy, it must first be realized that diplomacy in
	the game of Empire is virtually unavoidable.  To what degree
	you involve yourself in diplomacy is the true measure.

	Diplomacy can be utterly disastrous for you.  It can also be
	very beneficial.  It can also be a mediocre tool that goes mostly
	unused.  If you master the techniques of diplomacy you will find
	yourself with a very valuable and powerful tool.  If you fail
	at grasping the basic concepts of diplomacy, then you may find
	yourself the quick victim of a diplomatic trick.

C)  General types of relations amongst nations in Empire
	1) No contact.  The two countries have never been in contact.
	2) Allies.  Several types:
		a) Old friends, or local site friends.
		b) People whom you trust more than other people
		   in the game, but are not entirely comfortable with.
		   Nevertheless, you ally with them for lack of allies.
		c) Enemy allies.  People whom you ally with whom you
		   intend to attack.  
		d) Undeclared allies.  You conduct a lot of business with
		   the country, but you do not officially declare your 
		   alliance. 
	3) Hostile.  Generally speaking, any country who is unfriendly
	   towards you.  May not necessarily be declared hostile. 
	4) At war.  If you have not figured out what this means, stop
	   reading, never play Empire, and go back to elementary school :-)
	5) Neutral.  The broadest category.  You've dealt with this person
	   but have not decided one way or another your relations.  It might
	   be a person from a previous game or a total unknown.  

d)  Types of diplomacy
	1) Active diplomacy
		You interact with the country on a very high level.  Whatever
		their relations with you, a lot of correspondence is going on.
		This is probably the easiest form of diplomacy to invoke.
	2) Passive diplomacy
		Low level contact only.  In essence, you do not work with
		this country.  Some goals served by this:  Country in question


User's Guide to Empire							 30

		learns little about you; Country in question may give you more
		info than you give him or her; etc..
	3) Indirect diplomacy
		Diplomacy through a middle country to another country.  This
		is most often seen in situations where a known friend is an 
		ally of a country you want to be allied with.  You attempt 
		to use your friend to convince the prospective ally to ally
		with you. 
	4) Median diplomacy
		Being the middle person in a triad or more of allies that
		may not be already allied.  This can be a VERY dangerous
		position to be in.  The other sides of the triad or more
		may have certain expectations of you, which go against what
		another country may want from you.  This is essentially 
		sitting on a fence. 

E)  Some goals that can be achieved through diplomacy:
	1)  Getting another country to ally with you so that you can
	    overfly his country at will without planes scrambling.
	2)  Getting two countries whom you dislike to go to war against
	    each other. 
	3)  Getting another country to perform an act that is beneficial
	    to you or your allies. 
	4)  Getting a reduction in price of certain commodities or articles
	    from another country.
	5)  Gaining an ally.
	6)  Assisting in destroying an enemy.



	One of the most dangerous means by which diplomacy can be used was 
	written about in the book "Red Storm Rising" by Tom Clancy.  If you 
	have not already read this book and you are an Empire buff, it is 
	strongly recommended reading.  This method is referred to as "The 
	Maskirovka" or "Masquerade".  It is often referred to as the "big lie" 
	by the victims of this trick.  Essentially it works as follows:

	a) You wish to attack another country, but would like to have things
	   sightly different before the attack begins.  
		o  You may want that person to be your ally before the attack 
		   so you can overfly him/her without being shot down. 
		o  You might want to get him/her to give you a loan prior to 
		   your attack.  
		o  You might want them to move their fleet off in another 
		   direction or in closer to your forts.
		o  You might want them to give you certain materials of war
		   that you can use in your attack against them.
	   All of these things and much more can be accomplished with 
	   the concept of maskirovka.  Decide what you want to achieve.
	b) You set out to give the impression to the target country that you
	   are in a particular state of matters.  This can be accomplished
	   in various ways depending on what you are trying to achieve.
	   You can have another country attack you for instance to make it


User's Guide to Empire							 31

	   appear that you need military arms or supplies to hold them off.
	   This is one small example of what can be done.  Ensure that the
	   image you are presenting can ultimately lead to getting what you
	   want to achieve accomplished. 
	c) You must be convincing in your impression.  Use all means reasonable
	   to ensure the target country is getting the right image.  Using 
	   e-mail with collaborating countries to coordinate such matters 
	   is often best. 
	d) As you begin feeling that you have achieved the correct image,
	   begin asking the target country for whatever it is you are trying
	   to achieve.  Do not come right out and say it.  That may cause
	   the whole trick to collapse on you.  Approach it sideways so to
	   speak, and try to get the target country to offer whatever it is
	   without you directly asking for it.  
	e) If the country agrees to the transaction of events you are seeking,
	   all is well and good.  You have achieved your goal.  Keep in mind
	   that if you have played the maskirovka well, you have not yet 
	   committed yourself in any particular direction with any sense of
	   strong commitment.  At this point, you can always back down from
	   your further goals for which the maskirovka was designed to help.
	   The maskirovka at this point will have given you a more favorable
	   situation without having committed yourself.  It may also have
	   enabled you to see more into the mind of your opponent, often
	   a valuable commodity.  
	f) If you have failed in your maskirovka, you may still have made
	   some gains.  You again might know more about your opponent than
	   before.  You might have reached some of your goals that the
	   maskirovka set out to accomplish.  Lastly, you have not committed
	   yourself in any particular direction, yet you have tried to
	   enhance your position.  Not a bad proposition. 

	There are many variations to maskirovkas.  The guides listed above are 
	very general at best, and are meant more to give you an idea of how to
	build a plan for maskirovka than anything else.

	Chess players who have ever played in matches or tournaments will 
	probably feel right at home in scheming a maskirovka.  You must try to 
	get into the mind of your opponent, understand what s/he sees from 
	his/her vantage point and get a feel for how you think s/he will 
	respond.  You must think as if you were your opponent.  Understand 
	their vantage point as best as you can.  Do not think of what you 
	would do in a given situation, think what they would do.  Think 
	consequences to every action you can take. 

	This usage of diplomacy is "active diplomacy", sometimes mixed with 
	"indirect diplomacy".  

	Another oft seen ploy of sorts is one in which you befriend a dying
	rich country.  They may be on there way out, and there may not be a 
	whole hell of a lot you can do for them.  However, befriending them 
	towards the end may bring you gifts of money or lower market prices 
	from them when they dissolve.  Show sympathy for their situation.  
	You can be sincere, or you may chose not to be.  Sometimes a dying 


User's Guide to Empire							 32

	country has no friends to whom they will leave their money.  If your 
	the first to show sympathy, they may be willing to give you much in 
	return.  This is an active form of diplomacy, but is rarely seen 
	except after a long period of passiveness relative to that country. 

	Posturing.  Probably the most common form of diplomacy.  This basically
	means presenting an image to a possible attacker that you are more 
	capable than you appear.  In general, people tend to believe it.  
	Consider the simple fact that generally speaking a good Empire player 
	spends a lot of time working on his or her country.  Then, let them 
	believe through posturing that they are at a greater risk than
	they actually are.  They may tend to get possessive about their 
	country and not want to risk its destruction and the eventual loss 
	of so many sleepless nights and hours building the country in the 
	first place. 


Summary: Diplomacy is a powerful tool.  Some players consider it the
	 most powerful aspect of the game.  In many ways that can be shown 
	 to be true.  However, do not let other facets of your country 
	 decline and spend a huge amount of time building an excellent 
	 diplomatic situation.  The success or failure of diplomacy depends a 
	 great deal on the other players perception of your words.  If your 
	 diplomacy fails, you may find that you will be forced to back up what 
	 you say with military force.

Chapter 7 :-: Setting up your defenses. 

	There are various means of "automatic" defense that Empire employs 
	against enemy invaders.  These can be outlined in three major areas:

	1: Home air defenses

		Empire has numerous planes and plane capabilities.  The higher
		your tech level, the better the planes you can build.  For 
		automatic defenses you are concerned with planes that have the
		"intercept" capability listed next to them in the command, 
		'show planes c'.
		
		Generally speaking, as some games diverge from this list, the
		planes that have intercept capability are: 
			a: Fighter 1       (also has VTOL capability)
			b: Fighter 2 
			c: Escort 2        (in SOME games)
			d: Jet fighter
			e: Jet fighter 2   (also has VTOL capability)
		
		These planes are based out of airbases (except for the VTOL
		planes which can scramble from airbases and non-airbase 
		sectors) and will automatically intercept incoming enemy 
		planes.  

		notes: 1: Planes will only scramble if there is petrol in
			  the sector they are scrambling from.
		       2: Airbases must be at 60% or better efficiency to
			  scramble.  This does not apply to other sectors
			  from which VTOL planes are scrambling, nor does it
			  apply to VTOL planes in airports.

		In this version of Empire it is VERY important to have a good
		home air defense network.  Having a great many planes with
		intercept capability without proper planning is not a good
		defense.  You must learn to use the planes wisely.

		Hints for good home air defense: 
		1:  Have airports within intercept range of each other.
		    A plane's intercept range is 1/2 of its range indicated
		    in the command 'show planes c'.  For example:

				Figure 10
		  Results from 'show planes capability'

-------------------------------------------------------------------------------

		    In this list of planes, only the Sopwith Camel plane is 
		    capable of interception.  It has a range of 6, and thus
		    it can intercept enemy planes up to 3 sectors away from
		    the sector it is based in.  Have your planes based in
		    sectors that are three sectors away from each other. 
		2:  Always have a substantial number of military in your
		    airports.  It is all too easy for an enemy to track
		    down your airport and capture it, thus possibly destroying
		    all your planes, and in the very least taking them 
		    from you. 
		3:  Ensure that all sectors that you have planes based in
		    have a sufficient amount of petrol for them.  Note that in
		    the above figure, the Sopwith Camel uses 1 fuel per 
		    mission.  Thus, having 10 or more petrol per Sopwith
		    would be sufficient. 
		4:  Do not base your entire defense on non-VTOL capable 
		    interceptors.  If you do, then your enemy can remove
		    your air defenses just by taking out your airports. 
		    Sopwith Camels (Fighter 1s) and Jet Fighter 2s are 
		    the VTOL intercept capable planes.  Sopwith Camels 
		    generally become useless for intercept duty as the 
		    game wears on.  After all, a paper airplane can not 
		    put up with cannon fire from an F-15 for very long!
		5:  It is a good idea to have each sector in your country
		    covered by at least two airbases (or non airbases from 
		    which your are basing VTOL planes).  This makes it more 
		    difficult for your enemy to locate where your airbases are.

	2: Forts and guns

		Forts will automatically fire on any enemy army units that
		attack land of the defending nation, assuming that the guns
		in the fort have the range to reach the aggressor.  This 
		also assumes that the fort has shells and military.
	
		Fort gun range is determined by multiplying the number of guns
		in the fort by the technology factor of the nation.  This
		number can be found in the nation report [see command: nation].


User's Guide to Empire							 35

		Here's an example of calculating your gun range:

				Figure 11
		      Results from a 'nation' report

--------------------------------------------------------------------------------

		To calculate the gun range, multiply the number of guns in
		the fort (up to a maximum of seven) by the number listed in
		"Technology factor" which is shown in this figure as 40.66.
		Then, divide the resulting number by one hundred and that
		is the number of sectors away the gun can fire at.  In this
		case, if you have seven guns the resulting range is 2.85 
		sectors.  Effectively, the fort can fire just short of three
		sectors away. 

		There is an additional aspect of forts which make them 
		useful as defensive sectors.  Military forces inside of 
		a fort have four times the defensive factor of military in
		most other sectors.  Ie, 100 soldiers in a fort is equal to
		400 regular troops if they are defending the fort.  

		Also note that forts can not be taken by paratroops dropped
		from planes.  They can only be taken via amphibious assault
		and overland attack. 

		Forts are generally useful along your border sectors early
		in the game and later on in the game throughout your country.
		Ensure that they each have sufficient (seven or more) guns
		and shells each, when you are able to devote that many guns
		and shells to them.  Forts are sometimes very critical when
		your country is being over run.  



User's Guide to Empire							 36

	3: Naval support
		
		Your navy will defend itself if it has the capability to do
		so.  Ships do not automatically come with guns when they are
		built; they must be provided with guns and shells by loading
		them onto the respective ship.  Most ships have the capability
		to fire guns.  Should a ship of your nation be attacked, it
		will defend itself if it can.  In addition, ships within range
		will also retaliate.  Note that submarines will *not* fire
		no matter how often they are fired at.

		Ships will not defend your land sectors. 

		If ships are attacked from the air, they will fire their
		anti-aircraft guns (which are the same as your regular guns,
		and again are not automatically installed upon their 
		construction).  Anti-aircraft guns on ships are pretty much
		worthless on defense.  Additionally, if enemy planes fly
		over your ships but do not attack those ships, your ships
		will not fire on them.  Thus having a line of ships as
		radar pickets will not work. 

	In addition to these three major modes of automatic defense, there
	are a few more minor ones.  
	
	Any gun in any sector of yours that is overflown by enemy planes 
	will fire on those planes if it has shells, guns,  and military 
	available. 
	
	Military in any sector of yours that is attacked will automatically
	fight back to the best of its ability.  There is no such thing as
	retreat in automatic military fighting.  In addition, there are three
	sectors which multiply the effectiveness of military within them.
	We have already mentioned forts in this capacity, in that they 
	multiply the effectiveness of troops within them by four.  Capitals
	and Banks multiply troops effectiveness by two, when on the defensive.

	Also note that Capitals and Forts, as previously mentioned, can not
	be taken by airborne paratroopers.  Neither can mountains. 

	Lastly, should sectors of yours be taken, the enemy will have to deal
	with your patriotic guerillas.  Guerillas will attempt to retake 
	sectors from the enemy every update until they are defeated (which 
	takes some time).  They are large in numbers, but have been known to 
	reach strengths of a hundred or more soldiers, though this is rare.  
	If they can not hope to retake the sector they may try to blow things 
	up in the sector the enemy has conquered.  This results in loss of 
	efficiency to the sector as well as reduction in the work capability 
	of the sector. 

	You have *no* control over your guerillas whatsoever.  They are 
	completely automatic.  Should guerillas win a sector back from your
	enemy then the surviving guerillas become members of your regular


User's Guide to Empire							 37

	military, and you can use them as such. 

	If your guerillas manage to take a sector back behind enemy lines
	it is possible for you to enlist reservists in that sector.  In
	so doing, you may throw a major thorn into the side of your attacker.
	This is a major reason for maintaining a large amount of reserves.

Summary: Automatic defenses in Empire are a critical part of every country. 
	 If your country can not defend itself then you can expect to be 
	 quickly over run.  Use the automatic defenses described in this 
	 chapter, and you will become a more difficult opponent.  Remember 
	 the three basic areas of automatic defense.  In addition, keep in 
	 mind that your airforce is probably the most important component of 
	 your automatic defenses.

Chapter 8 :-: Nuclear warfare.

	Nuclear war in Empire is not currently the dreaded end of the world
	doomsday machine it is in the real world.  Nuclear weapons in the 
	standard release of Empire have no fallout, no radiation, no dust
	clouds, etc.  Nuclear weapons in Empire are essentially big 
	conventional bombs.  They are "clean" weapons in that the only 
	difference between them and conventional bombs is that they are
	bigger and create nuclear wasteland.

	As such, a nuclear war is much more survivable.

	There are several things that you need in order to wage nuclear
	war against an enemy.  First, you need the nuclear warheads themselves.
	You will also need a missile or plane of sufficient type and range to 
	launch the warheads on.  Lastly, you need to have target information, 
	ie where to land the nuclear warhead to cause the damage you want it 
	to cause. 

	Next, you need to decide if it is worth the cost to wage a nuclear
	war.  Should the enemy country know where you are, and have the means
	to retaliate in kind, s/he will most likely do so.  This can cause
	grave damage to your own country, and eliminate any gains you may have
	achieved by beginning a nuclear war. 

	There is also the large chance of great diplomatic cost.  Most 
	countries do not tend to favor countries that rely on nuclear weapons 
	for victory, since it is the "easy" way out. 

	However, the scenario that the beginner needs to be most concerned
	about is being the victim of a nuclear attack.  Most beginners never
	come close to achieving enough strength to have an effective nuclear
	force.  It may take several games before you become practiced enough
	to maintain an economy and military that is capable of having the
	resources, etc. necessary for such a force.  Nuclear weapons can be
	bought from larger powers, however the beginner still rarely tends
	to have these. 

	In the event that you are attacked with nuclear weapons you need
	to take immediate steps in order to ensure your survival.  You must
	first decide if it is in fact worth it for you to continue.  Most
	nuclear attacks are survivable.  In many cases, you may be hit by
	only one warhead.  Depending on the size of your country, a small
	number of warheads hitting you is survivable.  This all assumes the
	warheads are of the 5mt variety.  5mt warheads create a wasteland
	that is 5 sectors long from left to right.  3mt warheads create 
	wasteland that is 3 sectors from left to right.  Diameter in both
	cases is the same north-south as east-west.  These are the only
	nuclear weapons that can really create serious problems for you.
	Other nuclear weapons cause problems, but are essentially nuisances
	that can be easily overcome. 

	The following is a map of your -20:0,-10:3 region.  You have been 


User's Guide to Empire							 39

	hit with a 3mt nuclear warhead at your sector -12,-6.  It wastelanded 
	7 of your sectors and damaged nearly the entire area.

		  Map of area hit by 3mt nuclear warhead

--------------------------------------------------------------------------------

	Here is a basic outline of what you will need to do should you be hit
	with one or more 3mt or greater warheads:
	
	1: Get food to the people in areas that need food.  Especially areas
	   that are partially or totally cut off from the rest of your country.
	   ON THE MAP ABOVE:  This would probably be necessary for all sectors
			      east of -12 and/or north of -4. 

	2: Distribution routes *will* be cut off by a nuclear hit.  Redo your
	   distribution routes around the nuclear wasteland areas.  Make sure
	   that your new distribution center has enough food to feed the people
	   you are trying to support with it. 
	   ON THE MAP ABOVE:  This would probably be necessary for all sectors
			      in the region. 
	3: Move people into the area affected by the blast.  Get highways in 
	   the area back up to efficiency as soon as possible.  This will 
	   allow for increased movement in the immediate area of the blast 
	   which could be critical to the survival of the people in that area 
	   as well as defense of the area. 
	   ON THE MAP ABOVE:  You will probably need to restructure your 
		              highway system in the region.  Move people in 
			      from the south-east (off the map).
	4: Lastly, try to get production back online in the area.  This is
	   not as critical as the first three things.

	Those are the essentials for recovering from a nuclear blast.  The


User's Guide to Empire							 40

	first three items should be done as soon as possible top to bottom,
	ie number one is priority one. 

	There are also defense considerations after you have been hit by
	a nuclear blast.  Your air defenses in the area might be wiped out
	which would allow your opponent to take over your land in that area.
	There are also steps you can use to shore up your defenses in the
	area while you are getting the area back on its feet:

	1: Enlist military in the region.  Looking at the map in figure 12,
	   You might do something like:

	[23:210] Command: enlist -20:0,-10:3 -25

	   That would enlist military in the region so that every sector had
	   at least 25 military in it.  Note that you can only enlist half of
	   the population in a sector at one time, but you can enlist in the
	   same sector over and over again.

	   Doing this would hamper an enemy's progress should they attempt a
	   paradrop assault in the region.

	2: Move undamaged or nearly undamaged VTOL fighter planes from the 
	   south-east (off the map) into the area.  Do not put them on
	   the airbase.  Provide them with petrol as well.  This will
	   shore up your air defenses which were damaged by the blast.  It
	   will also make it much more difficult for an enemy power to attack
	   by air in the region. 

	3: Move guns and shells into the forts on the map if they are not
	   already there.  Make sure there is at least 7 guns and a lot of 
	   shells in each fort.  Also make sure there are substantial military
	   forces in each.  This will help prevent extended military action
	   on land by an enemy. 

	4: Move naval forces into the region if possible.  This will help
	   to prevent amphibious assaults.

	If you do all of these things, recovery from the blast will not
	take long at all.  These things will minimize the effect of the
	blast and get the area back on its feet again.  

	Do not be dismayed by loss of resources etc.  You *can* recover.
	I have been a victim of nuclear war probably half a dozen times,
	and so far have found only one case in which I was crippled by 
	the effects.  My entire homeland (of ~100 sectors) was 
	wastelanded except for less than 10 sectors.  No, I could no 
	longer hope to win the game, but I did hang on long enough to 
	purchase a nuclear warhead and missile and attack the person 
	who nuked me.  Doing something like this will make the player 
	who nuked you respect you more in future games, and consider 
	the consequences before pushing that button.

	It has become fairly routine lately for games to end with a world
	wide nuke-off.  Generally speaking, nations having nuclear weapons
	threaten the world with destruction if they are not acknowledged
	as victors.  Other people protest of course, and nuclear war happens.
	A game that has taken eight weeks to evolve to that point can be
	destroyed in less than an hour in the hottest nuclear wars.  This
	of course does not lead to any clear cut winner, and is rather 
	pointless but people do it anyway.  It is after all, a game, and
	people want to have fun.  Nuclear war, to many people in Empire,
	is fun. 

Summary: Do not be demoralized by a nuclear attack.  Powers using nuclear 
	 weapons expect their opponents to get demoralized. Recovery from a 
	 nuclear attack of larger degree is possible as well.  It takes 
	 perseverance and sometimes hard work.  Don't be dismayed by mass 
	 starvations.  Populations can recover if you work at it.  Your 
	 reputation may be greatly improved if you do recover from a nuclear
	 blast.



User's Guide to Empire							 42

Chapter 9 :-: Technology.

	By most people's definitions technology or the means to purchase
	technological weapons from another country is one of the most 
	critical elements in doing well in Empire. 

	Having technology allows you to:
	1.  Have increased ranges on your land based radar.
	2.  Build higher capability planes.
	3.  Build more advanced types of planes.
	4.  Build higher capability ships (not as great an effect as in planes)
	5.  Build more advanced types of ships.
	6.  Build bridges.
	7.  Build nuclear weapons.
	8.  Have increased ranges on your guns in forts.

	Thus, having a high technology country is a very useful thing.
	However, attaining a high technology level is very difficult for
	the beginner.  Running a country that has an economy balanced well
	enough to produce technology at a rate sufficient to stay in the
	technology race is a very difficult task, even for players who are
	more experienced and/or have a lot of allies supporting their 
	economies as well. 

	Producing tech is expensive.  It costs a lot in terms of money
	and materials.  Not only do you have to produce tech, but you
	have to educate your people to a high enough degree that tech
	production can be done efficiently.  Doing this takes a great
	many light construction materials (lcms) for education, and a 
	large amount of oil, gold dust and lcms for tech production.
	
	It is not uncommon for tech nations to be one of the smallest
	and poorest nations around.  Most of their time and resources
	have to be devoted to tech production rather than ships for 
	exploration and military to defend outlying colonies. 

	Do not fantasize.  If you are a beginner, forget about producing
	tech no matter how good you think you are.  You will be wasting
	your resources in doing so and crippling your economy while other
	countries will run far far ahead of you in production. 

	In general, until you have played a few games it is far better to
	purchase high technology items from other players.  Diplomacy, 
	discussed at length in chapter 7, is an effective tool for
	purchasing technologically superior items.

	Should you decide to run tech, there are several things you should
	know.  If you are able to take these into account, and balance these
	factors against each other you may be able to produce tech at a 
	sufficient rate to stay with the leaders. 

	Education is important to produce tech.  You have to have an
	education level of at least five before you can produce any.  However,


User's Guide to Empire							 43

	an education level of five will produce tech only in an inefficient 
	manner.  The higher your education level, the more efficiently tech
	will be produced.  This means that a single tech center can produce
	more tech per update, and cost you less in raw materials, though it
	will cost the same per unit of tech produced.  The savings in raw
	materials is critical. 

	Some countries feel it is better to keep your population low when
	they are planning on having a high education level.  The reasoning
	behind this is that it takes less effort to educate a small number
	of people and costs less money as well.  There is a bad side to this
	plan though.  With a small population it is hard to produce things
	in large quantities, and exploring into and occupying new lands is
	very difficult. 

	Technology production demands a large amount of resources.  Especially
	oil.  However, the higher tech you are the more oil you are able to
	refine per amount of crude oil in the ground.  Thus, it is better to 
	only take out of the ground what oil you need to keep your country
	running, and leave the rest for later on when you have higher tech,
	and get more per barrel of crude.  Thus, if you were to do the 
	following:

	[23:512] Command: resource 4,0

	You might see that your 4,0 sector has 100 units of oil in the ground.
	At tech 0 you'll be lucky if you get 500 barrels of oil out of that.
	However, at tech 100 you will probably get somewhere around 700-750. 
	That's a big difference.  So, only take approximately what oil you will
	need for each update out of the ground, and leave the rest for later.

	Tech production also requires gold dust.  Gold dust mining is not
	affected by tech like oil wells are.  Thus, mining the gold dust
	right away or saving it later has no impact on how much is produced 
	per unit of gold dust in the ground.  There are other considerations
	though.  If you have a lot of gold dust sitting around in your 
	warehouse or other storage place, other countries will see via the
	power report that you have a lot of dust.  If they are low on dust they
	just might look at you as a possible target.  So, if you are going to
	mine a lot of your dust right away you might want to consider putting
	a good portion of it into banks where the dust gets converted into
	bars, which will give you more money per update.  This especially 
	applies to the Kent State version of Empire, where you can grind up
	your gold bars into gold dust at a loss of 20% of the original amount
	of dust put into the bars.  

	Uncompensated workers are also useful for tech production, as well
	as many other things.  However, it has been noticed that a tech
	center with 999 uws will produce tech less efficiently than one with
	500 uws.  The loss in efficiency is greater than what is expected 
	from the tech limitation function, which is a non-linear function
	designed to limit fast tech production.  Most players do not feel that
	the loss in efficiency is worth it for the greater amount of tech


User's Guide to Empire							 44

	production, especially in small countries where having two or even
	three tech centers is unrealistic due to the small amount of land
	available.

	As your technology increases, the possibility of there being an 
	outbreak of plague in your country increases.  This is not of great 
	concern until such time as your plague factor (found by the command
	"nation") increases above a factor of 3.0 or more.  Even if plague 
	does break out in your country, if the plague factor is less than
	3.0 or so, the plague will have minimal effect on your country. 
	During your first outbreaks of plague, you will lose some civilians
	but the birth rate of the civilians will be greater than the death
	rate.  Thus, increasing your research level (by opening and operating
	a research center, which requires the same materials as a tech center)
	prior to your plague factor reaching 3.0 is actually a waste of 
	resources, time, money and effort.  This fact has been lost on a
	great many people and it is not uncommon to find many players 
	boasting of a high research level long before you would have a 
	plague factor of 3.0 without any research production.  While we
	have emphasised "3.0" as a point at which things start getting
	bad with plague, that is a vague figure.  Things start getting
	bad before that point, and get worse afterwards.  Its a matter of
	how much you want to put up with civilians dying off.

	There is a command called "report" which will list other countries,
	their status, and their levels of tech, research, and education 
	relative to you.  If your tech is significantly higher than 
	say a country called 'Canada' then report will indicate that
	Canada's technological level is 'backward' relative to you. 
	If Canada's technological level is significantly higher, than
	report will indicate 'advanced', meaning Canada is advanced
	relative to you.  If its roughly the same, 'similar' will be
	shown.  There are two other possibilities, 'primitive' and 
	'superior' which are used for extreme differences in levels.
	It should be noted that report is inaccurate at best, and only
	gives a very vague idea of levels.  

Summary: Technology is one of the basic aspects of having a country that
	 lasts to the end of the game.  Generally, the higher tech you are
	 the greater chance of your survival.  However, if you have a high
	 technology friend, you chances of survival are still increased
	 greatly.  Empire is a classic case of cold war as far as 
	 technological development is concerned.  As a beginner, you are 
	 probably better off not producing a great deal of tech until you 
	 become well versed in how to run a strong economy.

	Special items:  Beaurocratic Time Units (BTUs), Available work (Avail)


				Figure 13
		  Table of types of commodities in Empire

--------------------------------------------------------------------------------

	Beaurocratic Time Units (BTUs) are used when executing a command, such 
	as "build" for example.  They are also used to shuffle paperwork 
	around, say for soldiers killed in combat. 

	Available Work (Avail) is used up by producing sectors and those 
	sectors in which you build things (planes, for example).  It is an 
	indices of the amount of labor hours available for work. 

	Running your economy efficiently as possible is one of the keys to 
	being a good Empire player.  Without a good economy it is impossible
	to wage a long lasting war, especially an offensive one.  It is 
	possible to last a long time defensively even with a weak economy 
	but your chances are greatly increased if you have a strong economy. 

	So, what defines an efficient and strong economy?  An efficient
	economy is one in which the amount of a product being produced in a 
	sector is nearly equal to the amount that the civilians can produce in 
	one turn.  For example, if a light construction materials (LCM) plant 
	can produce two hundred LCMs an update, but is only producing one 
	hundred, then fifty percent of the people in that plant are basically 
	doing nothing.  They could be used elsewhere on something that needs 
	more civilians or you could put more iron into the LCM plant to allow 
	the civilians to make more LCMs.



User's Guide to Empire							 46

	A strong economy is an economy that produces a lot of materials,
	resources, etc relative to the size of the country.  If your country
	has only say ten thousand civilians but is producing a large amount
	of materials per update then your country may in fact be a strong 
	country.  This is a very unlikely scenario, but it is a good example.  
	A strong economy is usually the result of an efficient economy, 
	though there are other factors, those mainly referring to population 
	growth.  To find out how much work your civilians are going to perform 
	at an update you can issue the "prod" command to get a production 
	simulation.  Using this you can see if all the civilians in a given 
	sector will be making something or if some will be sitting around and 
	doing nothing.  Here is a sample output from a prod command:

				Figure 14
		     Sample output of the 'prod' command

--------------------------------------------------------------------------------

	The important columns to note here are the "will" and "max" columns.
	If the number indicated in the "will" column is less than the "max" 
	column by more than 1, then you have civilians who are sitting around 
	doing nothing.  The way you calculate the number of civilians you have 
	sitting around is fairly simple.  First, it is important to note that 
	the number indicated in	the "wkfc" column is the number of civilians 
	and uncompensated workers (UWs) you will have in the sector *after* the
	next update.  You need to reduce the number of civs and/or UWs in the 
	sector to optimum *before* the next update.

	For this example, and for sake of ease, I am going to assume that
	there are no UWs or soldiers in this sector, which both produce work.  
	We will assume that there are only civilians, and happy, content ones 
	at that.  Civilians that are starved, or recently starved do not work
	as hard. 
	
	In the above shown production simulation there are two sectors which
	have civilians sitting around idle.  These two sectors are the bank 
	('b') at -10,2, and the library ('l') at -8,4.  We will use the library 
	for our example.



User's Guide to Empire							 47

	The library is going to produce 40 education, but it is capable of
	producing 239.  It doesn't have enough lcms (the only material needed 
	to produce education) to produce 239 education.  Thus, only the civs 
	necessary to produce 40 education are actually working.  The remaining 
	number of civilians, as a percentage, is calculated by this simple 
	formula:

	((# in max column) - (# in 'will' column)) / (# in max column)

	Thus, the percentage of civilians in the library not actually doing 
	work is (239 - 40) / 239, or 83.26%.  That's a large percentage!  Now, 
	to calculate how many civilians you can move out of the sector without 
	reducing your production beneath 40 education in that sector, multiply 
	.8326 * the number of civilians currently in that sector.  So, you need
	to do a census command:

--------------------------------------------------------------------------------

[162:166] Command : cen -8,4 
Mon Sep 30 20:19:07 1991
CENSUS               del dst

				Figure 15
		Results of a 'census' command of a library

--------------------------------------------------------------------------------

	There are 403 civilians listed in the 'civ' column for the library at
	sector -8,4.  Thus, you multiply 403 by .8326 and you find that you can
	safely remove 355 civilians from that sector and still be producing
	40 education.  That's 355 civilians that can be doing valuable work
	elsewhere instead of sitting around doing nothing! 
 
	The other alternative to get the sector producing efficiently
	is to move lcms into the library up to the number that the library can
	possibly process with the current number of civilians.  Once again, we
	refer to the production report and note the 'use1' and 'max1' columns.
	The library will use 40l (40 lcms) at the next update unless you put
	more lcms into the library.  It can use up to 239 (239l in 'max1') 
	lcms.  Thus, it can process an additional 199 lcms.  So, you find lcms 
	somewhere else in your country and move the 199 lcms into the library.
	At the next update your library will produce 239 education.  Once 
	again, all of the civilians in the sector are now doing something. 

	Of course, you can also use a combination of these two methods to
	achieve an equitable balance. 

	There are other aspects to running an efficient economy as well.
	Ideally, you do not want to have an abundance of raw materials lying 
	around especially in the early stages of the game.  The best situation 
	is to have your economy using the same amount of resources per update 


User's Guide to Empire							 48

	as it is making, thus having a zero delta situation with respect to 
	all materials in your economy, you neither gain nor lose surplus of 
	materials.  Keep in mind however that it is important to create and
	maintain a surplus of materials from which to draw on in times of war,
	especially later on in the game.  Without spare materials, you can not
	wage war very effectively.  In doing this you are getting the best 
	balance of production, and are producing finished items at a faster 
	pace then if you spent more work producing raw materials.  If you 
	spent more work producing finished materials, you would run out of 
	raw materials, and find that you have to move your civilians around 
	to produce more raw materials or have them sitting idle doing nothing 
	while your other civilians produce sufficient raw materials for them 
	to do work.  The benefits of a balanced economy are obvious. 

	There are additional tasks that are somewhat rewarding in running an 
	efficient economy, but they become increasingly technical in nature 
	and their impact as a whole against your economy is significantly less.

	As you become more experienced you will no doubt discover these thing 
	yourself, or hear about them in a game or on the network.  These basic 
	elements are more than enough for you to run smooth production if you 
	adhere to them.  

	There are still more elements of an economy which, while very useful, 
	are not exactly related to the strength or efficiency with which your 
	economy is running.  Your country, should it live for some time and 
	develop a well balanced economy, will produce a huge amount of 
	materials.  It is impossible for you to keep track of everything in
	each and every sector of your country.  Of course, the Empire creators
	realized this and have developed some critical commands for reducing
	by a very large amount the quantity of time you need to spend adjusting
	your economy.  These are the 'distribute' and 'deliver' commands.

	'Distribute' and 'deliver' are commands in Empire which allow
	you to set up your economy to run automatically, with little 
	intervention from yourself.  Distribution is the most commonly used 
	command in doing this.  However, deliver has certain features which 
	are useful as well. 

	Distribute is based on the central warehouse scheme of production
	and consumption of materials.  An iron mine produces iron, which it 
	ships off to the central warehouse.  A light construction materials 
	plant needs iron to make lcms, and thus requests iron to be sent to it 
	from the warehouse.  The lcm factory produces lcms, and sends them 
	off to the warehouse.  A library plant needs lcms to produce 
	education, and requests lcms from the warehouse to do so.  The 
	warehouse handles regional traffic for your economy.  Some smaller 
	countries only have one warehouse. 

	Deliver is based on the local delivery truck idea.  A nearby farm
	produces a certain amount of food per update, and sends it directly to 
	the neighboring sector.  You know that the neighboring sector can 
	consume more food per update than that farm can produce (this is very 


User's Guide to Empire							 49

	rarely true, this is just an example).  So, the farm sends all the 
	food it produces to the neighboring sector.  The neighboring sector 
	notes how much food has been delivered from the farm, and then requests
	from the warehouse enough food to feed the rest of the civilians in 
	the sector.  In so doing things in this manner, you are possibly saving
	mobility by not having the food automatically move to the warehouse 
	from the neighboring farm and then to the neighboring sector.  The same
	result would be achieved however, though as stated at a possible 
	greater loss of mobility.  Nevertheless, most people prefer to depend 
	entirely on 'distribute' to handle automatic distribution of materials 
	around their country. 

	To set up a distribution system, or network, you have to set a 
	distribution 'path' *from* every sector *to* the warehouse.  I 
	emphasize the direction that the path is moving in because all 
	distribution paths go *to* the warehouse, not from the warehouse 
	to the sector, though materials can and will go from the warehouse 
	to the sector along that same path.  The idea here is say a farm 
	outside of St. Louis about 50 miles produces 500 units of food, the 
	farm needs to know the route by which it should send its trucks to get 
	to a warehouse in St. Louis before it can send the food to that 
	warehouse (this of course being a real life scenario). The best path 
	to choose is across highways.  A 100% highway requires no mobility to 
	move anything in to it.  Obviously you don't want to travel the 50 
	miles to St. Louis across dirt roads.  You would prefer an interstate
	if you were a truck.  In Empire, a 100% highway is essentially an 
	interstate.  Your goal is to have a distribution path from each sector 
	to the warehouse travel the route over the least mobility cost path.  
	The greater the percentage of that path that is 100% highways the 
	better.  It is important to note that distribution paths have a maximum
	length of 10 sectors.  For example:

[529:32] Command :

				Figure 16
		  Map of area requiring some distribution

--------------------------------------------------------------------------------

	Let's say that in the previous figure you wanted to set up a 
	distribution path from the oil well at -15,1 (the 'o' sector left of 
	the middle of the map) to the warehouse at 0,2 (the 'w' sector right 
	of the middle of the map).  The command to set up the distribution 
	path from that oil well to the warehouse would be: 

--------------------------------------------------------------------------------

[529:32] Command : distribute -15,1 nnnjujjjuj
oil field at -15,1 has no distribution path.
<10: 0,2>h
New path distributes to 0,2

[534:31] Command :

				Figure 17
		    Results of a distribution command

--------------------------------------------------------------------------------

	Now there is a path along highways from the oil well to the warehouse.
	If you do not understand the nnnjujjjuj command above, refer to chapter
	3 and the section under "movement in Empire".

	Next, you need to set thresholds for the sector.  This sector is an 
	oil well, and it produces, you guessed it, oil.  So, you want the oil
	that is produced to be shipped to the warehouse.  You have to tell the


User's Guide to Empire							 51

	people in the oil well that all oil over 1 unit is to be shipped.
	This is called a "threshold", a level at which any quantity of that
	unit over that amount if shipped to the warehouse.  Note that the 
	lowest threshold you can have and still have the item shipped is 1.  
	If the threshold is 0, then it will not be shipped.  The command to set 
	the threshold in the sector -15,1 for oil is:

[534:31] Command : threshold oil -15,1 1

	Next, you want to make sure that food gets out to the oil well.  The 
	other aspect of thresholds is that if there is less than the threshold 
	of a commodity, then the warehouse will send out enough of that 
	commodity to equal the threshold, assuming it has such commodities in 
	the warehouse.  The command to set the threshold for for in the sector
	so that food will go to the sector from the warehouse could be this:

[534:30] Command: threshold food -15,1 50

	Which means at each update, the warehouse will attempt to ensure 
	that there is 50 food in the oil well at -15,1 by sending enough 
	food, if it can, to raise the stockpile of food in that sector to
	50 units.  

	Again, distribution paths must be set up for every sector that you 
	intend on doing anything with.  Essentially, as the game progresses, 
	this means all of your sectors.  You must also set appropriate 
	thresholds as well.  Some sectors need iron from the warehouse to 
	produce, and thus a threshold will be required for iron.  Some need 
	more than one commodity, so thresholds must be set for each of those 
	commodities.  EVERY sector should have a threshold value set for food.
	You do not want to starve your civilians!  To find out what 
	commodities a sector needs to produce an item, use the 'production' 
	command discussed earlier in this chapter.

	Some things to note about distribute: 

1) No distribution path may be longer than 10 sectors.
2) A distribution path must go through sectors controlled by you.
3) Sometimes it may seem that the warehouse is not getting the commodities
   to the sectors requesting it.  Empire updates sectors one at a time, and 
   as such the warehouse may actually run out of a commodity, receive the
   request for that commodity, be unable to fill it and move on the the
   sectors it updates after that sector.  Those sectors in turn may send
   commodities to the warehouse, thus giving it enough to fill the previous
   request.  However, since it has already updated that sector, it will not
   fulfill the backlogged request.  Empire updates the world left to right
   and top to bottom.  Thus in a map of your country the most north-west
   sector gets updated first and the most south-east sector gets updated last.
4) The warehouse has to spend mobility to send commodities to the requesting
   sectors.  Warehouses do this at a great reduction in the cost to the 
   normal mobility.  However, if the warehouse runs out of mobility it
   will NOT distribute any more commodities for that update. 
5) Do NOT set thresholds for all commodities in a sector.  Only set the 


User's Guide to Empire							 52

   thresholds for the commodities you KNOW that sector will need.  Distribute
   will not distribute commodities to sectors with the thresholds set for 
   every commodity. 


	Deliver is much more basic.  As a result however, it is much less 
	powerful, though it is useful.  Deliver works as explained earlier in
	that it does local deliveries of a specified commodity.  Deliver is
	capable of delivering an item to only neighboring sectors.  During the 
	update, deliver is done before distribute.  It is important to note 
	that.  Let's say that a farm has a lot of food to send to the 
	warehouse.  It may not have the mobility to send it all to the 
	warehouse, and thus you get a large surplus left over in the farm.  
	Eventually, the farm will not have room to store the surplus anymore.  
	This is of course bad, since the farm will no longer produce very much 
	food.  It will produce only enough food to replace what was taken from 
	the storage at the farm.  

	The solution to this is to have the farm sends its surplus to a 
	neighboring 100% efficient highway.  This will cost the farm no 
	mobility and will open up its storage areas for new production at the 
	farm.  The highway can then spend mobility sending the food to the 
	warehouse.  Once again, we use the map:

				Figure 18
		   Map of an area requiring delivery path

-------------------------------------------------------------------------------

	Let's say the farm at -5,-1 (just north of the middle) has a huge 
	surplus of food.  You can send that surplus to the highway at -4,0 by 
	issuing this command: 

[566:115] Command : deliver food -5,-1 n (50)



User's Guide to Empire							 53

	Which means, deliver all food in the sector at -5,-1 in excess of 50 
	units in the 'n' direction.  Note the deliver threshold in parentheses 
	must be in parentheses and that deliver thresholds are different than 
	distribute thresholds.  

	While I have described how to use the basics of deliver, I do not
	recommend it for the beginner.  Using a distribution network is quite
	sufficient for the beginning player, and you will not notice any great
	difficulty in running your economy without using the deliver command.
	In fact, some of the best players in Empire do not use deliver at all.


Summary: The things discussed in this chapter may seem time consuming, and 
	 may seem to require a lot of detail.  However, these things are 
	 important to you as an Empire player to learn and understand.  They 
	 become easy to use after only a short while.  Having a strong 
	 economy is the basic element in having a strong country.  If you 
	 have not understood this chapter, read it again.  Better yet, read 
	 it while experimenting with a couple of your own sectors in a game.  
	 While understanding 'deliver' is not very important, understanding 
	 'distribute' is.

Chapter 11 :-: War

	The art of waging war is certainly beyond the scope of this guide.
	There are a great number of books written on the history of man's wish 
	to destroy themselves.  In this chapter, I only intend to give the 
	player some rudimentary basics for waging Empire style wars.  Even more
	pertinent in the case of the beginner, how to defend against or 
	hopefully repulse an invader.

	Keep in mind that as a beginner, you stand a very good chance of losing
	your first war.  Consider it a learning experience.  The person who
	defeated you is better than you are in most circumstances, and just by 
	their actions you can learn how best to wage an offensive or defensive 
	war. 

	There are several things that you can do to defend your country
	in the event of an attack.  However, it is always best to be prepared 
	for an attack before it happens.  There are some basics already 
	discussed in this guide on these preparations.  Refer to chapter 8
	for information on automatic defenses, and how they can help your 
	country.  I will review the essentials here.

	1) Have a strong airforce with many fighter planes with the intercept
	   capability.  Make sure they are used as indicated in chapter 8.
	2) Have forts with overlapping fields of fire. 
	3) Have a large number of reserves (typically 1/10 of your population).
	4) Have at least two enlistment centers ready to produce more fresh
	   recruits.  Ie, at 100%.  You can "shut off" enlistment centers, that
	   is stop them from producing recruits, by leaving 1 civ in them
	   or having a military population in the sector equal to one half
	   of the civilian population.  To turn them on, put in more civs or
	   reduce the number of military.
	5) Have a strong navy to guard your coast.
	6) Mine your own coast.  This prevents many amphibious assaults.
	   It also helps to prevent people from mapping your coastline. 
	7) Have a good highway network.  This allows you to move materials
	   and armies around your country quickly and with ease.  
	8) Have more than one capital.  If your real one is taken, you will
	   need a back up immediately. 
	9) Have a lot of food in all of your sectors if possible.  This allows
	   sectors that are cut off from your warehouse to be self sufficient
	   at least with respects to feeding the people with food for a few 
	   updates until you can open up a path to them. 

	These are just *basic* hints.  Some more hints are given later in this 
	guide.  These are meant to get you started. 

	Of course, it is better to not be attacked at all.  But, how do you
	avoid being attacked?  This is not simple, but there are some things
	that you can do to make yourself less of a target. 

	One, do NOT allow people to map your coast using their ships, 
	especially patrol boats.  Maps of your coastline are deadly.


User's Guide to Empire							 55

	The opposing country knows where your country lies, and can furthermore
	send that information on to another player who might be interested
	in attacking you in exchange for some commodity or assistance.
	Maps are a critical piece of intelligence gathering.  Some of the 
	best players in the game sink ships on sight without warning.  If you
	warn a ship off it might be able to use some of its mobility to
	make a final swing along your coast before going away, and seemingly
	out of your hair without having caused further trouble.  Every piece
	of information about your coast is valuable military intelligence.
	Additionally, it is a good idea to try to map other people.  Do not
	get upset when your ships get sunk.  They will get sunk.  Just consider
	them expendable commodities that are doing a temporary job with 
	permanent results.  

	Two, if you appear tough people generally will not attack you.  
	Posturing can be an effective tool.  Furthermore, if you have a large 
	airforce and/or army, people tend to avoid you.  It does not matter if 
	your airforce only has wimpy planes in it, your opponent can only 
	tell the quantity of planes that you have, not the quality.  They 
	might have a general idea of the quality of your airforce, but a large 
	airforce is still an intimidating presence. 

	Three, do not make yourself a target by having a lot of valuable
	commodities showing up on your power report.  Having lots of money
	in a money poor game for example makes you a juicy target.  The same
	holds true with gold dust or oil.  You need not worry about iron and 
	food, since those are renewable resources.  Try to use gold dust and
	oil as you make it.  Having some surplus around is fine, but the more
	you have sitting around the more of a target you become. 

	If you are attacked, it is always best if you are logged on to the game
	so that you can actively defend your country rather than relying 
	entirely on automatic defenses.  However, as can obviously be seen, you
	probably will not know that your enemy is going to attack you.  Neither
	will s/he broadcast that they are going to attack unless they are very 
	foolish or extremely confident. 

	In light of this, your opponent will try to attack you at a time when
	they know you are not logged on.  Thus, a great many Empire wars begin 
	in the wee hours of the morning, when most people are asleep.  What can
	you do to overcome this shortcoming?  Have allies for one.  If one of 
	your allies is going to be up most of the night you can have them 
	telephone you if you are being attacked.  Of course, this is for the 
	more diehard types :-)

	There are many tactics that an enemy will use against you.  Again, 
	these tactics are beyond the scope of this guide, but there are some 
	general tactics that you should be aware of.  An opponent may try one 
	or more (usually more) of the following tactics:

	1) Remove your airforce as an effective retaliatory force.
	2) Remove your airforce as an effective defensive force. 
	3) Take your capital (you lose half your money).


User's Guide to Empire							 56

	4) Take your banks (you could lose all your gold bars, very valuable!).
	5) Destroy your highway system.
	6) Take your warehouses (lose your stored commodities. OUCH!).
	7) Bomb your enlistment centers.
	8) Take your radar stations.

	
	In addition, your opponent may try to destroy your distribution and/or
	delivery system (if you so opt to use deliver).  After you take a 
	sector back from your enemy check the thresholds and distribution path 
	in the sector.  Sometimes if you take a great deal of sectors back it 
	is best to just use the 'wipe' command and start from scratch.  
	Remember to check your delivery thresholds as well, by issuing a 
	'level' command.  Your opponent will probably also redesignate the 
	sector to something useless or even detrimental to you.

	It is important to be on around update times when you are at war,
	either defensively or offensively.  Things can go very quickly right 
	before and after an update. 

	One of the best ways of being a good military tactician is to be
	imaginative.  Think of ways to do things that might surprise your 
	opponent.  Think of ways to do things that will cost you less lives, 
	or less resources than your original way.  

	There is a saying that sometimes the best defense is a good offense.
	This can be very true in Empire.  If you are attacked it might be a 
	good idea to launch a counter attack against your opponent's homeland
	if you are able to.  This will certainly surprise them, and may lead 
	them to think you are stronger than you actually are.  This can be a 
	very powerful tool.  

	If you want to win the war, be resilient and tenacious.  Fight as hard
	as you can with every last soldier and resource.  If you make your 
	enemy pay a heavy price they may withdraw.  Sometimes breaking an 
	opponent's will to fight is the most important factor in winning a 
	tactical or strategic situation.  Even if they do not withdraw, or you 
	do not win, you may at least be helping to defend the future of your 
	allies.  That in itself is an honorable achievement.  There is also the
	point that if you are a tenacious fighter your opponent will respect 
	you more in future games than if you just roll over and play dead while
	his/her armies pillage your country.  Reputation does count for a lot in
	Empire.  You may lose now, but your defiance in losing can help you a 
	great deal in future games.  Some countries simply will not attack
	another country because they know that country's reputation as a good 
	player.  Alternatively, some countries have a poor reputation and
	are attacked in every game they play in!


Summary: The art of Empire war is one that is different from the real life
	 world that we live in.  However, many tactics from the real world
	 can be applied to Empire.  Remember to be imaginative, learn from
	 your mistakes.  Learn from your allies and your opponents.  Fight
	 as if it was a real world nation, and you are the leader.

Chapter 12 :-: Other helpful or not so helpful hints:


	Here are some hints on how you might be better able to run
	your country.  Note that a lot of these hints were garnered through
	many player years of play.  You are free to disagree with them, and
	are certainly encouraged to come up with your own ideas.  However,
	keep in mind these recommendations.

	- Build your military reserves to a reasonably high level
	  (I try to aim for 5-10% of my total population).  Reserves are
	  not expensive to maintain, and it is a commodity that can not
	  be destroyed by any military action.  
	- As soon as someone starts building ships guard your coastal
	  sectors with at least 1 military in each.  This prevents an
	  opponent from making landings in mass quantity on your homeland
	  with measly cargo ships.  If you have military in a coastal sector
	  then opponent ships really need the "land" capability (see 
	  show ship capability command for further insight) in order to be
	  truly effective.  Guard harbors with more military, say 50 or
	  so.  Else an opponent can assault a harbor, move his or her invasion
	  fleet in, unload the ships and walla several hundred foreign military
	  are sitting in your former harbor. 
	- As soon as planes start being built, try to get at least 10 military
	  into every sector.  This makes it more difficult for a country to
	  wipe you out quickly.  In this manner they usually need 2 or more
	  transports to take a single sector.  This makes it costly in air
	  mobility for them and softens the blow of their attack.  In addition
	  reinforce capitals with a lot of military.  Same with banks, airbases,
	  and warehouses.  
	- Do not base your entire air defenses on non-VTOL (vertical take off
	  and landing) planes.  Base your VTOL planes in non airport sectors.
	  In doing this, you prevent your enemy from knocking out your airbases
	  through any number of means and then flying at liberty over your 
	  country.  There are two VTOL fighters.  Fighter 1s, which are 
	  essentially biplanes with very brave souls in them and Jet Fighter 2s
	  which are akin to the British Harrier jet.  Fighter 1s are not 
	  necessarily a bad plane.  Against low tech transports they do not
 	  fair too badly.  There are two other means of air defense if your
	  airbases are knocked out.  Anti-aircraft guns exist in any sector
	  that has guns and shells.  They will fire if the sector in question
	  is at war with the planes in question.  They are mostly worthless.
	  The other method is SAMs (surface to air missiles).  These can be
	  quite effective but are shoot once only weapons.  
	- Forts are an integral part of any home auto-defense scheme.  They
	  will fire on any enemy aggressors that are within range whenever
	  any sector of yours within range is attacked. 
	- Naval units become essentially useless later on in the game except
	  for some actions.  Nevertheless, be careful to have naval units in
	  appropriate places around your coast for coastal defense.  Especially
	  until you have planes that can pinpoint bomb well (jet lt bombers,
	  jet f/bs, helicopters). 
	- Always have several fake capitals in reserve.


User's Guide to Empire							 58

	- If you are not using planes that are 100% and are not planes used
	  in air defense, get them off your airports.  Otherwise they become
	  easy targets for air assault and bombs.
	- Bridge span sectors are effective means of food production and
	  are especially useful in that role in countries with few sectors
	  or countries with limited fertility.  They are usually somewhat
	  expensive to build, but pay for themselves quickly.
	- Keep in mind that allies are important.  You might want to go it 
	  alone, but at some point along the way you will need an ally or 
	  three.  Allies can do many things for you, not the least of which
	  is call you over the phone when you are under attack at four in the
	  morning.  Its nice to know that even though your country is not
	  being played, someone is watching it from a distance and seeing
	  whether it gets attacked or not.  You sleep easier :-)
	- If you are positive there is no one else on your island with you
	  at the beginning of the game then demobilise your military and
	  put them on reserve.  This will save you a lot of money, and help
	  in population growth. 
	- Never put airports, banks, or capitals on your coast.  They are 
	  easy targets for your enemies if you do.  Sometimes it is necessary
	  to place an airport on your coast to get that extra one sector
	  of range for your planes in an attack.  If you do that, don't leave
	  your planes in that sector for very long.  You might be surprised.

Summary:  Many of these ideas can only be gained through experience.  Do not
	  be come distraught for lack of knowledge.  Experience is a wonderful
	  teacher.  These hints cover some of the major pitfalls of beginners,
	  and that is all.  There are far more things to be learned that can
	  only be taught through experience.

Chapter 13 :-: Some tricks and subtle tactics

	I have listed here some of the tricks used by the more advanced
	players in victimizing the beginning players.  I  divulge this hard won
	information because I feel it will make for a better Empire game for 
	everyone.  In reading these, I hope that you will be encouraged to 
	develop tactics of your own.  It is not hard to be imaginative. 

	Note that not all tricks and subtle tactics will work as advertised.  
	Some games have slightly different implementations that have a 
	negative effect on these hints.

	- Sacking a warehouse.  This is an old tactic that is useful
	  only in those games that have a market.  Essentially the trick is to 
	  take an opponent's warehouses or distribution points and sell off 
	  everything that is in the sector to the market.  You don't need a 
	  buyer immediately, just sell everything off.  If you want the items 
	  for yourself, sell them to the market at an exhorbinately high price 
	  and wait for a friend to buy them and sell them back.
	- Tracking an airbase.  This is a less known trick.  Non-VTOL planes
	  intercept from airbases.  They also intercept from airbases in a hex 
	  pattern.  Ie, if the plane has a six sector intercept range it will 
	  intercept up to six sectors west, six sectors north-west, etc in all 
	  the six directions.  If you can find two corners of that plane's 
	  interception hex you can triangulate to find the sector from which it
	  is intercepting.  This does work for VTOL planes as well, but isn't 
	  as useful since airbases usually have far more planes in them to be 
	  dealt with.  Once you have tracked the originating sector of the 
	  intercepting planes, what you do to that sector is your option.  Most
	  often, a concerted effort will be made to crack the defensive fighter
	  cover and blast the airbase.  Sometimes countries will use their 
	  surface to surface missiles (which do not get intercepted) to take 
	  out the airbase.  For non-VTOL planes taking out an airbase just
	  means getting it below 60% efficiency.
	- Fort "walking".  If you have a land border with a country, you can
	  use your forts to demolish a bordering sector with that country.
	  By demolishing it, your are completely destroying every living 
	  civilian and soldier in that sector.  When that is accomplished you
	  can explore into that sector as if it were wilderness.  You can then
	  designate that sector into a 0% fort, which it will become 
	  immediately, and then move guns and shells into that sector.  
	  Then, you can do the same thing to a sector bordering your new
	  sector.  In this manner you can slowly invade another country
	  beyond a one sector advance in one update without the use of
	  planes or ships.  This costs A LOT of BTUs and shells, but in
	  critical situations is very useful. 
	- Fire base.  This tactic has some relation to the tactic used in
	  the Vietnam conflict by U.S. Forces.  The idea is to take an enemy
	  sector in an area that you want to wreak havoc on.  Next, use your
	  pinpoint bombing capable planes to bomb your own position's sector
	  efficiency.  You will have some collateral damage on your troops,
	  but it is well worth it.  When the efficiency drops below 5% you can
	  then designate the sector into a 0% fort, place guns and shells 


User's Guide to Empire							 60

	  in it using air transports, and then have a base from which to 
	  blast away at your enemy without the use of much airpower.  It is 
	  possible to use the fort walking tactic from this position.
	- Messing up a country's distribution paths and or thresholds.
	  This is most often an "annoyance" tactic.  Most players know about it
	  and check the distribution paths and thresholds of sectors they take
	  back from an invading country.  The idea is to set the thresholds so 
	  that a lot of commodities will be distributed to the sector from the 
	  warehouse of your opponent after your opponent takes the sector 
	  back.  Then you can take the sector again and get the commodities 
	  if s/he has not noticed they are there.  Even if s/he notices it is 
	  a pain getting the commodities back to the warehouse.  
	  Alternatively, you can screw up the distribution path to run through
	  a mountain and then to his warehouse, and also set the thresholds 
	  of the commodities quite high.  This will cause mobility in her/his 
	  warehouse to be used in great quantities to get the commodities to 
	  the recaptured sector.  Either of these ideas can get particularly 
	  nasty.  Say you conquer a sector, and set the thresholds on food to 
	  9000 units.  Your opponent takes back the sector, and neglects to 
	  reset the threshold.  At the next update the warehouse moves 9000 
	  food (or at least as much as it can) into the sector.  This might 
	  leave your warehouse without food to deliver to the rest of the 
	  country.  Food stocks begin to drop, with obvious repercussions.
	- Messing up a country's delivery routes and thresholds.
	  Same as above except using deliver.  Many countries do not use 
	  deliver at all, and as a result are susceptible to this tactic.  
	  You can cause mass starvation in a country that you attacked, but 
	  no longer control without the leader ever knowing how. 
	- Destroyer trap.  Move a submarine near a destroyer, say one sector
	  away.  Lay some mines from the submarine, and then send out an active
	  sonar ping using the "sonar" command.  Enemy destroyer rushes over to
	  see what it is and KAWHOMP! hits a mine.  You can leave a sector that
	  has mines in it safely but can not necessarily enter safely.  Every
	  mine laid in a sector increases the chance of a ship hitting a mine
	  while entering that sector by five percent.
	- Determining if someone is on.  You can get an idea of when someone 
	  is usually logged on by doing something like this:

[65:255] Command : news 10 | grep 

	  This will scan the news file from the server for the last ten days
	  (or however many days up to ten are being preserved in the news).
	  You can then get an idea of when your opponent is logged on.
	  There are tools that can do this for you, but so far none has
	  reached public distribution. 
	- Attacking any sector with one soldier repeatedly.  Within the code
	  there is a small chance that against incredible odds a small 
	  collection of soldiers might win.  Taken to the extreme, there is
	  a chance for one soldier to win, even against 400 soldiers, or so
	  says the game.  Thus a player who wants a particular sector bad
	  enough, may spend thirty minutes attacking a sector of yours 
	  over and over again with one military.  They might win eventually,
	  and if it is important enough then they have gained a major sector.


User's Guide to Empire							 61

	- A player might offer to sell you a type of commodity in several
	  batches.  Or, you might just start buying batches of a commodity
	  from any given commodity.  If the player you are buying from is on,
	  they might change the price on you between batches that you are
	  purchasing.  For example, DoDo starts buying food in batches of
	  9000 from WabbleHead at 10 cents per food.  This costs DoDo $900
	  per batch of food.  Suddenly between DoDo's 2nd and 3rd purchase
	  of 9000 food, WabbleHead changes the price on the food from 10 cents
	  to 10 dollars per unit.  DoDo never realizes it and pays $90,000
	  for the 3rd batch of food.  Moral:  Don't purchase anything without
	  checking the price first, and never buy in several batches at once.
	  This applies to market and trade.
	- It is possible to move small quantities of a commodity across any
	  sector in your country and not have it cost mobility.  To do this,
	  you have to have the commodity moving from a warehouse to whatever
	  sector you want to move it to.  The basic trick, is to move the
	  commodity in batches of 5 or less.  Note this does not work for
	  bars, and some other commodities.  It does work for food, shells,
	  etc; items that do not take a great deal of mobility to move to
	  begin with.  This trick is very effective for getting supplies
	  to a region cut off from your main area without highway access
	  and possibly even a mountain range separating you from it. 
	- Mine your coast.  This prevents your opponents from effectively
	  mapping your coast, and you can catch their ships in the act since
	  a damaged ship moves a lot slower than a 100% ship.  Some people
	  might even scuttle the ship in question to avoid detection.
	- Be aware that submarines will try to map your coast.  Use your
	  submarines and destroyers to find them.  Use minefields as a 
	  preventative measure. 
	- Do not give out your net address to anyone except the Deity unless
	  people offsite can not finger you, or you have an account on 
	  another machine, and can regularly play from it.  People can finger
	  you over the net to see if you are logged in or not.  If you're not,
	  it's a good time to attack probably. 
	- Beware of people offering you loans.  Make sure you know the terms
	  of the loan.  Someone might offer you a loan that looks nice, say
	  for $30,000.  But, the loan might expire in one day and have an
	  interest rate of 127%.  The lending country can collect sectors
	  directly from you without your permission if you are in arrears
	  on the loan. 
	- Defend your radar stations.  Always have at least 20 military in
	  each of your radar stations, especially ones that are on the coast.
	  Otherwise a passing ship might decide to capture it and take a 
	  snapshot of your country. 
	- If a sub attacks one of your ships, it is possible to wander around
	  the area with a ship that is not capable of sonar or depth charging,
	  and still find that sub.  How?  Try boarding the sub by its hull
	  number.  If a sub attacks you, you will get a message saying that
	  sub number so and so did such and such to your ship.  Use a ship
	  in the area to wander from sector to sector trying to board the 
	  sub.  If you find it, you will get a message saying that you can not
	  board a sub.  Walla, you have found the sub without sonar, which
	  other ships can hear anyways.  This is a nice quiet form of anti-


User's Guide to Empire							 62

	  submarine warfare. 
	- You can load a missile cruiser full of anti-shipping missiles, and
	  then create a script file with firing commands for every ship in
	  existence.  Remove your own ships of course.  Then execute the
	  script, and the missile cruiser will fire at only those ships 
	  that are in range, regardless of whether the ships are in radar
	  range of the cruiser or not.  They need only be in range of the
	  anti-shipping missiles.  This is an effective, if blundering, way
	  of removing approaching fleets before you see them on your radars.
	  Note: anti-shipping missiles are not available in standard BSD code, 
	  but are available in some other versions, namely the Kent State 
	  code.


Summary: Be sneaky.  Be imaginative.  Think of tricks you can pull on your
	 opponent.  Quite often, they will in fact work.  Most players of this
	 game are not Rommels, Pattons, or Montgomerys.  Many can be duped 
	 by very simple tricks.

Chapter 14 :-: Tools

	Tools are programs used by players on their local machines to 
	assist them in developing their country, analyzing another country, 
	conducting war on another country, etc.  Tools are very powerful 
	devices at times.  As such, many players have tools that they consider 
	to be military secrets and they do not release copies of them.  As a 
	result, many programs doing basically identical tasks have been 
	written.  I encourage those players that are reading this that have 
	such secret tools to release them to an anonymous FTP site with a 
	directory for Empire.  Not only does this make the game better for the 
	beginners, but it also helps to keep the experts on their toes, and 
	give a challenge to those of us who have been playing for quite some 
	time. 

	Some players feel that playing with tools takes something away from
	the playing aspect of the game, and feel that in so doing they are not
	really playing the game anymore.  This has lately turned into a 
	religious war of sorts in the Empire community, with many people taking 
	both sides of the coin.  

	You do not need tools other than your client to play Empire. 
	Empire is designed such that any player can play the game without 
	hindrance without the use of a tool other than the basic client itself. 

	What follows is a list of tools that are most commonly found
	among players of the game.  Most of these are publically available at
	an FTP site listed in Appendix C. 

Tool		Purpose
autodist	Automatically sets distribution paths for an entire
		country or realm within the country.
autofeed	automatically feeds the people in your country.
pmvr,civmvr	Automatically redistributes your population so that sectors
		will be able to have population growth rather than maxing
		out at the limit of 999 civilians.
econ		Provides an analysis of your country's economic progress
		at the next update.  
GEET		Gnu-Emacs Empire Tool.  An emacs interface for Empire that
		has a great many capabilities and functions.  Provides for
		better automatic defenses as well.
EIF		A more advanced client than the basic client.  Allows
		for aliasing commands, command editing, etc. 
XEMP		Empire client for X windows.  Provides many nice features
		including an on screen map constantly displayed.  A very
		nice interface that unfortunately still has several bugs.

	These are just a few of the Empire tools out there.  There are still 
	many more programs not listed.  Some cover news analyses, country
	analyses over several updates, etc. 

	Most tools come with documentation on how to use them, and it is
	beyond the scope of this guide to illustrate how each one of them 


User's Guide to Empire							 64

	is used.

	There are other aids that are often called tools which are called
	scripts.  Scripts can do a great many things for you.  The most common
	of these applications are simply files containing a list of commands 
	that you want to execute in Empire.  

	For example, let's say that at each update you wanted to dump the 
	current news into a file in your local directory, get a new power
	report and dump that into another file, and dump all current telegrams
	into yet another file.  This would be three commands that you could 
	consolidate into one command by doing this:

	Construct a file in your local directory that has the appropriate
	commands in it.  In this case you could write a file with three lines:

news >>news.file
power new >>powerfile
read >>old.tele

	You could call this file update.do

	While in Empire you could then request the Empire client to access
	that file and execute those commands by using the exec command followed
	by the file name.  Thus:

[102:253] Command: exec update.do

	Building such a simple script is useful for doing a set of commands
	over and over again without typing it in each and every time.

	Lastly, remember to exercise wisdom in the use of tools.  It is 
	possible that the execution of a simple tool can damage your country 
	irrepairably.  Use tools, especially those written by others, with 
	caution.  Try them out on small sections of your country first.  Look 
	at the source code prior to running it if you have access to the 
	source code.  It is theoretically possible for someone to write
	a tool that will scan the list of countries in a game, and if the
	author's country name is in that list, send valuable information
	about your country to him or her.  Yes, it is true, some people
	have no morals believe it or not.


Summary: Tools are very powerful items if used wisely.  It is not necessary
	 to have tools to play Empire effectively.  Some experts of the game
	 refuse to use tools of any type, and they remain among the best 
	 players.  Tools are no replacement for skill.  Be careful when using
	 tools, they can ruin your country.

Appendix B :-: Known exploitable bugs

	As a result of Empire having several thousand lines of code, there
are numerous bugs.  Some are simply annoying, others you never notice.  Some,
like the following, are bugs that you can be used against you.

	a) "Intercept" bug - Non-VTOL planes can and will rise and intercept
	   hostile planes from any sector as long as there is petrol in the
	   sector, the plane has the intercept capability (see show plane c),
	   it is at least 40% efficient, and it has mobility. 

	b) "Escort" bug - Planes that are capable of escort duty can escort
	   themselves on various missions, as long as they are capable of
	   the mission in question (such as a bombing raid).  Say for example
	   that you want to fly a reconnaissance mission over enemy territory,
	   but you know that enemy planes are going to intercept you.  
	   When the game asks you for the plane that will be doing the recon,
	   you can give it plane 345 for example, which for the sake of 
	   this guide is a jet fighter.  When it asks you for the planes
	   that are going to escort it, you can say 345 again.  The game will
	   respond as if two planes are flying the mission when in fact only
	   one is.  Enemy planes will think there are two planes.  Enemy planes
	   will first do battle with the escort.  Let's say they did 16% damage
	   to the escort, and the escort did 14% damage to one of the enemy
	   interceptors.  Next, the enemy interceptor attacks the recon plane,
	   which is the same plane, and inflicts 21% damage.  The recon plane
	   inflicts 13% damage on the interceptor, and the recon plane aborts
	   the mission.  It looks like you lost the dogfight.  In actuality,
	   you did not.  The intercepting plane suffered a total of 27% damage.
	   It looks like you suffered 37% damage.  However, you actually only
	   suffered the *last* damage inflicted, which was to the recon plane.
	   Thus, you only suffered 21% damage and you won the dogfight. 

	c) "Flying Bridge" bug - Say for example you have a 100% bridgehead
	   sector with enough HCMs, workers, and avail to build a bridge. 
	   Normally, you would say "build bridge x,y" and then it would ask
	   you for a direction to build the bridge.  If after you built the 
	   bridge you were to redesignate the bridgehead, the bridge would 
	   collapse.  However, if you redesignate the bridgehead sector 
	   before you build the bridge, the bridge will be built and will 
	   not collapse.  At the next update, the bridgehead will become
	   the sector you redesignated it to (say, a highway) and the bridge
	   will still be there.  Note: It is believed that most current
	   games of Empire have a new patch that prevents this bug.

	d) "Resource sucker" bug - Let's say you have a sector with 23 gold
	   content left, and it is a gold mine.  Normally it might produce
	   say, 111 gold dust at the next update.  If you were to put 9000
	   civilians into that sector, it would produce over 900 dust at 
	   the next update.  The sector's resource content of gold will go
	   to 0, but instead of getting a roughly 115 dust from the sector
	   with the remaining content, you have gotten over 900 dust.  
	   Civilians reproduce quickly enough that losing 8000 civs this way


User's Guide to Empire							 68

	   is really of no concern especially when you consider what you
	   have gained.  This bug works also for oil wells and uranium
	   mines. 

	I have listed the bugs here because it is important that players 
	know about these bugs in case they are used against them.  I do not 
	condone the use of these bugs, nor do many players of the game.  
	Many deities (the people who run the game) take action against 
	players using these bugs, such as taking away your technology or 
	your money.  Do not use them.  Simply be aware that others may use 
	them and come up with ways to counter their use.  If you are aware 
	that another player is using one of these bugs, report it to the 
	deity of the game.  S/he might give you a reward of some sort. 

	Also note that since these bugs have been published> here, it is likely
	that some programmer has written bug fixes for these.  Most, and 
	possible all of these bugs might not work in a game you are 
	participating in.

.NA Hints "Hints to help you play Empire better"
.LV Expert
.s1
Military and the Demobilization of Same
.in +0.3i
.s1
It's generally a good idea to put
demobilized military on active reserve.
You should also consider whether you need an enlistment center
to generate more military.
You can't enlist more military than you have military reserves.
The \*Qnation\*U command will tell you how many military you have.
Be careful, as many players have lost their countries
through carelessness with their military
at the start of the game.
.s1
Actually, the enlist command cannot activate more military than
you have on reserve.
Even then they have to be in sectors
with an efficiency of 60% or greater.
Enlistment sectors can produce as many military as they are capable of,
but will never produce more than one-half
of the civilian populace there.
So you need to keep moving them out, or demobilizing them, etc.
Also, the more military you have in an enlistment center,
the more military get trained per update.
.s1
Any civilian may be enlisted
(no restriction on the efficiency of the sector).
No more may be enlisted than the number of reserves.
Enlistment costs mobility whereas
while demobilization costs cash.
Military can only be demobilized in sectors
with a 60% efficiency or greater.
No more than one-half the number of civilians in a sector
may be enlisted in one \*Qenlist\*U command,
but if it is issued many times,
virtually all civilians in a sector may be enlisted.
.s1
One thousand reserves is enough for now,
although I figure I always put them on reserve when I demobilize,
at least up to 10,000.
.s1
So you don't need to push for more reserves now,
but might as well put all demobilized military on reserve.
.s1
You make back the cost of demobilizing military in just
two or three days I think,
so I generally demobilize the military I don't have any use for,
and put them on reserve.
.s1
Depends on how you want to use them, I guess.
I figure with 200 jet transports at 127 mobility,
I can land 20,000 military in an enemy country in one night,
so I'd say 20,000 is a safe upper limit for reserves.
I've never needed more than that.
.in
.s1
Distribution Hints
.in +0.3i
.s1
When distributing stuff to a warehouse,
set the thresholds in the sector that is sending to or receiving
from the warehouse to the amount that you want left in that sector.
Don't set thresholds for the warehouse itself
(unless its also distributing to another warehouse)
.s1
The minimum threshold for distribution is one.
A threshold of 0 means no distribution of that commodity
will take place.
.in
.s1
Something to Remember about Technology
.in +0.3i
.s1
An education level of five is required to build technology.
After "easy tech", the tech you build is put through a
logorithm with "tech log base" (see version).
.in
.s1
War Zones
.in +0.3i
.s1
It makes it much easier if the player doesn't
have to do anything to keep his country running,
but can instead do the things that are of interest.
There's also the problem of what to do in an invasion.
I guess if invaded I just accept the damage,
and don't try to fix it until the war ends.
.s1
In a war zone I generally follow one of two basic plans.
If I'm the invader, I either leave the sectors as they are
and let the country being invaded fall apart,
or if I can do something to make it worse for the enemy,
I sometimes do that.
I sometimes designate conquered sectors to agribusinesses
if they need food, banks to reduce shelling damage,
enlistment centers for military,
forts for firing and attacking, harbors to get ships in,
warehouses to collect, move, and distribute supplies,
airbases for planes and bridge heads for easy movement.
.s1
When being invaded, I also generally postpone any
long term development and just concentrate on the
basic sectors types for combat (a,b,c,e,f,h,w,#,*)
.s1
I've found it's a mistake to worry about long term
development in a war zone, until the battle is over.
I will let a war zone be completely wrecked in order to achieve victory.
So you need to keep your home area away from any war zones.
.s1
So far the method of treating war zones and
peaceful zones differently and keeping them separated
has worked pretty well.
The mistake I made in the past was to try to develop a war zone
before the fight was over.
Now I'm willing to completely wreck the area to win,
and in fact you pretty much have to.
The guerrillas take several days to get rid of even when
the war is over.
.s1
I mostly turn the sectors in the front lines into forts, enlistment
centers, banks, and bridgeheads.
Then maybe some warehouses, airports, and harbors
within range of the front lines.
And maybe some radar stations.
.in
.s1
Work Percentages are Important!
.in +0.3i
.s1
I've found it good policy to produce a large surplus
of food and aim to have at least 100 food in each sector,
when I have enough. Actually I now put 990 food in each
sector, except for aggies (100) and warehouses (9990).
.s1
Before moving civilians,
check the work in the sector the civilians are in.
If it's less than 100%, DON'T move any of them out.
The reason: work in the destination sector will drop to
the same level as the starting sector.
.s1
It's a good idea to check after every update,
to see if any sectors have work less than 100%.
\*Qcen\ #0\ ?work<100\*U is what I use.
If work is less than 100%, workers won't work at full efficiency,
and if it gets very low,
the civilians may revolt and you'll lose the sector.
Build lots of happiness, and keep extra mil in sectors with
work less than 100%.
That seems to help.
.in
.s1
Definitions and a Good Thing to Remember
.in +0.3i
.s1
\*QWorld tech\*U and \*Qworld research\*U refers
to the technology and research made by other countries
which will automatically leak to the less developed countries.
.s1
If you let education get higher than happiness,
then find work going to 0% in your sectors,
don't say you weren't warned....
.in
.s1
On Nuclear Devices
.in +0.3i
.s1
Just a note on nukes: in this version, there is
a nice balance between nukes and economics.
A player can do a lot of damage with nukes, but it costs a LOT.
So it's rare that a country is completely annihilated
by a nuclear attack,
as used to be the case in PSL Empire.

.NA Kill "How to kill your process on the server"
.LV Basic
.s1
At some point you may lose your connection to the game.
When this happens its possible that the game will not
log your country off and you will get a message saying that
you are still playing the game.  This can be easily fixed by the player
if you type in the following.
.s1
.nf
.in +1i
telnet your.local.empire.machine 6666 
coun   
pass  
kill
quit  
.in -1i
.fi
.s1
What happens is that you are connecting directly to the Empire Server.
From there you enter your country name and password.
You can then kill the job that's running and then quit so you can
login again using the client.
.s1
This little trick will work on just about any Empire game.
Of course you need to telnet to that game and
and enter the correct country and password.
.s1
Its a good idea to write this down somewhere and DON'T LOSE it cause
chances are that you will have to use it at sometime.
.s1
Note that many clients offer a "kill" command which does this.

\*(iFA Preface\*(pF
by Ken Stevens
.s1
While most of this document applies to the game of Empire in its
current form, it is important to keep in mind that the sections which
follow this preface were written long before missions or land units
were introduced into the game.  The main impact that missions and land
units have had on the game is that they greatly strengthened the
defense.  Here are "ten easy steps" for setting up a strong defense in
the new server:
.NF
(1) Build 100% forts and put 10 guns and at least 100 shells in them.
(2) Put at least 5 mil in all of your coastal sectors.
(3) Build infantry units, put them in the forts, "fortify" them, and
    put them on "reserve" mission (info mission).
(4) Build battleships and artillery and put them on "interdiction"
    mission.  Put the artillery in forts and fortify them.
(5) Put infantry units in your banks and capitals, fortify them, and set their
    reaction radius to 0 (info lrange).

---later in the game---

(6) Put lots of land mines in your ground (info lmine).
(7) Build fighter planes.
(8) Always guard your ships with destroyers (or other kinds of ASW ships).
(9) Build some ASW planes and put them on interdiction mission.
(10) Build lots of sam's and abm's.

\*(iFA Treatise of Advice on War and Peace
for Budding Empire Players\*(pF
by Dave Pare
.s1
This article contains advice for beginning players.
It deals mainly with staying alive and not economic development,
because staying alive is tougher for beginners
than is playing with the various Sector-types.
.s1
The most important thing I can say is that beginners should remember
that Empire is not realistic.
There are dozens of \*Qtricks\*U to learn;
until you master them, you will lose because of small oversights
Beware of patterning your Empire actions after real-world strategies;
they may not work as expected.
.s1
When you start, grab as much land as possible.
Locate and identify other players,
and get an idea of the size of your land mass.
Send them all telegrams.
Everybody likes to get telegrams;
the telegram facility gives you the chance to make friends,
influence people, and have fun role-playing your country.
If you get to know somebody,
you may not be attacked because you come across as a nice guy.
Of course, if you sound like a bozo, you may get stepped on.
.s1
Establish a definite border with your neighbors by inhabiting
sectors with one civilian.
This establishes your claim
to the land behind these outposts,
even though you don't actually occupy it yet.
It also prevents your neighbor from discovering where YOUR capital is.
In Empire, it's very important to protect the location of your capital;
likewise, it's quite nice to know the location
of the neighboring capitals \*Qjust in case\*U!
.s1
If any of your neighbors attacks your outposts,
that gives you a valuable clue to their intentions,
while not costing you much in the way of resources.
Also, an attack on a remote outpost may give you enough time
to prepare your country for the possible invasion to follow.
You may not want to claim too much land though,
or the outposts will get overrun by people
who are fed up with your obvious land-grabbing.
.s1
Basically, try and be fair about land distribution,
but make sure you get a good deal for yourself.
.s1
Empire players go to war for many reasons.
One is lack of resources;
you have land, and they want it.
Another is safety;
your troops or ships are perceived as menacing,
so they are destroyed by your adversary.
Another is because the attacking player
really enjoys attacking people!
Still another is boredom and/or curiosity --
\*QJust how do nukes work anyway?
Hey, I know, I'll try them out on Freedonia!\*U
.s1
In Empire, wars are generally won by people who attack first.
Because mobility can be saved up
your attacks can proceed while the hapless enemy is asleep.
Many Empire attacks have happened over the weekend,
or at 2:00 in the morning.
It is quite difficult to defend your country when you're not logged in.
The auto-defense features of the game are minimal at best.
.s1
The whole philosophy of \*QFirst Strike\*U holds true from early land
warfare, to naval warfare, to the philosophy of Mutual Assured
Destruction.
If you strike first and your attack is well-planned,
any retributive strike of the enemy's will be ragged at best.
If it's a land war,
all of the fighting will be on the enemy's territory,
not on yours.
Your industries will be fine, and the battleground will be the enemy's.
.s1
Having mentioned the advantages of pre-emptive strikes,
I must caution against spur-of-the-moment attacks.
I've noticed that many wars tend to occur because
some country sinks your battleship;
you get mad and decide to attack.
I'm just as guilty of this as anyone.
Spending a few days marshaling your forces
can mean the difference between a long, drawn-out slugfest,
and an overwhelming 2:00 blitzkrieg
that blows away half the enemy's army and navy
within the first few hours.
While it's nice to have instant gratification
(seeing enemy troops die right after you read the telegram
describing the destruction of your poor, defenseless battleship
feels SO good),
a hasty counterattack will alert your enemy
who will mobilize forces and retaliate accordingly.
Things will escalate, and you'll be in a full-scale shooting war
before you can say \*QGulf of Tonkin Resolution!\*U
And you will have lost the advantage.
.s1
Going first only counts if you have marshaled your forces.
A scattered, ill-planned attack will net you nothing
but a little instant gratification,
at the cost of a long drawn-out war in which
your neighbors who aren't fighting are the only winners.
Once two countries are at war,
it's much harder to win \*Qovernight\*U.
Vietnam is a good example of what you shouldn't do.
Gradual escalation just gives the enemy time to prepare.
A sudden, overwhelming attack is far better
and will achieve your goals much more cheaply.
.s1
Knowing where the enemy is located is absolutely critical
to the planning of a successful attack.
.s1
War takes up a lot of resources;
your personal time is the most precious resource of all.
In a war, your time, energy, and creativity will be devoted
towards destroying your adversary.
This leaves little time for economic development.
In war, the home front stagnates, or goes to seed.
Only the bare necessities are produced for the civilians at home,
technological innovation and new land development ceases,
and your country will generally fall behind in the global race
for technology.
.s1
Therefore, if you decide to go to war,
you'd better win quickly
or else it will take a lot of time,
and your country will go downhill fast.
If you're just punishing someone for doing something \*Qnasty\*U,
offer \*Qnice\*U peace terms after you've meted out
appropriate punishment.
If you aren't attacking because you're bored,
other players are likely to agree to peace
because losing a war is unpleasant.
I've turned enemies into allies often enough;
they are happy to survive,
and if your attack was relatively justified,
they are happy to have you as a friend.
.s1
You'll notice I didn't give any advice to responding to an attack.
I think being attacked is generally a losing proposition
because in Empire the attacker generally has the advantage
unless fighting with greatly lower tech equipment.
.s1
As soon as ships start appearing on the power chart,
make sure each sector bordering water
has at least five to ten military.
When more ships come around, beef up the coastline defenses even more.
Put tons of military in your capital.
.s1
To summarize,
if you go to war, strike the first blow -- preferably at 0200.
.s1
Remember the cost in your own personal time investment.
Once the ball starts rolling,
you won't be able to call it all off and go for a vacation.
Your enemy will want to kill you,
so you'd better be prepared to spend plenty of time in solid play.

\*(iFHumble Additions to the
Treatise of Advice\*(pF
by Tom Tedrick
.s1
In addition, keep mobility in mind.
In many of my low-tech wars, superior mobility was decisive.
.s1
Combining these ideas gives you my basic opening strategy:
take as many sectors as is possible, as quickly as possible
(I will take 300 sectors the first day if I can),
and designate them highways, leaving one civilian in each sector.
(You may need to leave one food in sectors with zero fertility.)
.s1
When my country first reaches 100% efficiency,
roughly two-thirds of my sectors will be 100% efficient highways.
This allows me to shift my forces all the way
from one border to another in a single move.
I once had great fun smashing three countries
that attacked me simultaneously from three sides
by shifting all my forces from border to border to border,
achieving local superiority in each case,
and annihilating the enemy forces in turn at updates
(this is related to the theory of the
advantages of interior lines worked out by the Germans).
.s1
If the enemy runs out of mobility you can sometimes catch
the main invasion force helplessly immobilized on the front lines
and annihilate it.
.s1
.ce 2
\*(iFHints to the Wise\*(pF
by Shelley Louie
.s1
Since this is an advice note,
I'll refrain from being too specific about tactics.
You'll just have to learn them yourself.
.s1
Building the Perfect Beast: (Country Construction)
.in +0.3i
.s1
The first thing you want is land.
Lots of land.
A whole hell of a lot of land.
You should try to expand your country from the very beginning.
From there, you'll meet your neighbors who are doubtlessly 
doing the same thing you're doing.
Expanding wildly.
Now comes the first of a series of decisions you have to make.
Do you want to become a raging power-mad warmonger?
If you do, be sure to have built your army beyond the basic 100 troops.
The earlier in the game you find someone,
the easier it is to crush them into oblivion.
If you feel peaceful, see the diplomatic section of the text.
.s1
Another difficult decision is designating your sectors.
A good beginning mix is two mines per light construction and
heavy construction factory,
about 20% agribusinesses
(later dropping to 10%, 5%, or even none at all!),
and a few schools, research, parks, etc.
to fill up some of the other space.
The most important thing to have is a good transportation system 
in the form of your highways.
Anywhere from 20-40% of your country should be highways.
You'll find them infinitely useful
in moving food to a starving sector,
taking people to a new settlement,
or transporting troops to a local revolution, highways are vital!  
.s1
Another important consideration is \*Qdo you want really want to win?\*U
This implies the idea of competing
in terms of building technology and research,
and being able to get supplies to continue to produce
both of these vital products plus happiness,
a high (greater than 10) education, maintaining a military force, etc.
Winning means succeeding on all fronts.
I play to win, but find that I can't devote the time or effort
to winning, so I usually end up playing for the pure enjoyment
of the game.
Ask Tom [Tedrick] how many hours he puts into playing,
and you can figure that is what you're going to have to do to win.
A final warning, if you play seriously, your grades will drop.
No if's, and's, or but's about this.
You can't just throw three to five hours a day away
and not have your schoolwork suffer.
.in
.s1
Happiness is a Warm Gun: (The Art of Diplomacy)
.in +0.3i
.s1
No one trusts anybody in this game unless you know them personally
outside of the limited scope of Empire.
Of course, this limits you a lot,
so you break the rules and make alliances
with people who you have no relation to.
And they in turn backstab you and devastate the country
you so meticulously built for the last few weeks.
Oh well, that's what you deserve...
.s1
Just kidding.
Most of the people you will play with are rather trustworthy souls.
At least they are until it becomes burdensome to them.
A good relationship (as all those sex manuals will tell you)
is based on trust and respect for the other person.
What does this mean to you?
Build enough military to be a pain to invade.
Military power insures respect.
Trust is up to the two people involved.
.in
.s1
Night Moves: (The Art of Empire)
.in +0.3i
.s1
Empire is a skill.
Never forget that.
You will learn as you play that you may have to stay up
for that 3:00 AM update to completely surprise your unknowing victim
or even just to maximize your country's potential.
Also never forget that someone may be up at that time
waiting to pounce all over you too.
Pleasant dreams.
.in
.s1
Running on Empty: (Losing and still having fun)
.in +0.3i
.s1
Okay, you've tried to keep up with Tom [Tedrick], Chris [Guthrie],
and all those other experienced people,
but it just isn't going to  happen.
You are not going to win the big win (i.e., become world dictator).
What do you do?
Give up and watch your country go to pot?
Give all your stuff away to another country and resign?
.s1
No!
You can have fun even after you can't win.
Make small wars with other small countries.
Try to get a hold of nukes to devastate them.
Form a cartel with other small nations
and try to run over a big country.
As in real life, the possibilities are endless!
Look at the Middle East, they're having fun, right? 
.s1
This is just a game, and from this point on,
you don't have to worry about watching over your nation too closely.
Play for the enjoyment of playing.
.s1
Which, of course, is the intention of Empire in the first place.

\*(iFOn the Distribution of All Things\*(pF
by David Bleckmann
.s1
The reader here is assumed to have read the information pages
on distribute, threshold, and level.
.s1
To use distribute, it is a good idea to have a warehouse.
You don't have to, but this is how the command usually works.
If for some odd reason you don't use a warehouse,
you will have to use some other sector as your
\*Qdestination sector\*U, as mentioned in \*Qinfo level\*U.
For novices, just build a warehouse.
I will refer to warehouse instead of distribution sector
for the rest of this text.
.s1
You should place your warehouse in a spot
that can be reached by all your sectors via a low mobility path.
That is, for each sector you own,
there should be a path along which you could move goods
at very little mobility cost.
Since 100% efficient highways don't cost any mobility to move across,
roads that come close to each of your sectors
and lead to your warehouse are a good idea.
.s1
Now for each of your sectors you must set up a distribution path.
Use the distribute command.
This is a path from each of your sectors to your warehouse,
along a low mobility path as described above.
For example, if you have a nation that looks like this:
.NF
	  j j m + c
         m + g * +
	  h + w + k
	   m + + g
.FI
And you wanted to set up a path from your capital,
you would give the command
.EX dist 0,0 bbg
.s1
Note: the path can only be so long,
and as your country gets larger you will
need more than one warehouse.
.s1
Once you have done this for all of your sectors,
you are ready to start distributing.
.s1
Now you will probably want to have food on all your sectors,
and if one sector has a lot of people on it,
you may want to have a bit more on it.
You will not want to have to monitor the food levels
for all of your sectors.
This is the process that is automated by distribute.
.s1
Using food as an example,
you can go through all of your sectors and issue a threshold command,
such as:
.EX thresh f 0,0 40
.s1
This will set the threshold for food at your capital at 40.
You can do this for all of your sectors using a command like
.EX thresh f #
.s1
And give a threshold for each of your sectors as prompted.
.s1
Now at each update,
Empire will move food to and from your warehouse 
in an attempt to satisfy all your threshold requirements.
If for example a certain sector
has more than its allotted threshold of a certain product
(e.g., an agribusiness producing food),
food will be moved off it to the warehouse.
If a sector has less than its threshold,
and the warehouse has any of that commodity,
the product will be moved from the warehouse
to the needy sector in an attempt to satisfy its threshold.
If a certain sector has a threshold of 0 for a certain product,
no distribution takes place.
.s1
Therefore if you wished to move as much iron as possible
from an iron mine every update,
you would set its threshold for iron to one.
If somewhere else you had a lcm factory that can use 45 iron a turn
(found out through the prod command)
you would set its threshold for iron to 45 (or greater)
and its threshold for lcm's to one.
Then, on each update,
Empire would move all iron off your iron mine (except for one unit),
try to put 45 iron on your lcm factory and take all lcm's
(except for one)
off your lcm plant
(possibly to be used somewhere else).  
.s1
Note: the order in which this happens is predictable,
but not always desirable.
Thus, if you have no iron on your warehouse to start with
and your lcm factory gets updated first,
it won't get any iron even though there will be some in the warehouse
in a few seconds.
It is always a good idea to keep surplus goods in your warehouse.
.s1
The end result is that you can set up your country to move your products
around without you logging in.
It also doesn't cost as many mobility points
to move things as distribute, and it costs no BTU's!

\*(iFSome Further Clarifications
on Distribution versus Delivery\*(pF
by David Muir Sharnoff
.s1
.in +0.3i
\*(iFSecondly, I am still a little confused
about distribution and delivery.
When I designate a distribution route,
does that mean that things will be delivered
from the point of distribution to the warehouse?
Or do I also have add the delivery route
on top of the distribution route in order to get things moving?
And how do I get the visual route of the distribution route?
I can get delivery routes by doing the route command.
Thanks.\*(pF
.in
.s1
The two methods of moving commodities
(distribute/threshold/level and deliver/cutoff/route)
are completely independent.
.s1
Delivery is most useful for short, one-sector, movement of commodities.
Distribute can be used in conjunction with highways and distribution
sectors to provide low-cost, long-range movement of commodities.
There is no analog to the route command in the distribute paradigm.
.s1
Here are some examples of commands:
.s1
.EX distribute -2,0 jjjh
This command sets up a distribution path from the distribution sector
in -2,0 to sector 4,0.
.s1
.EX thresh food 4,0 400
This command sets the threshold on sector 4,0.
Sector -2,0 (the distribution sector for 4,0)
will attempt to keep 400 units of food in 4,0
by importing or exporting as necessary.
.s1
.EX thresh oil 4,0 100 
This command is the same as above,
but will instead attempt to keep 100 units of oil.
.s1
.EX level -2,0
This command will report the distribution routes
and thresholds for sector -2,0.
.s1
.EX deliver food -2,0 (384) y
This command will deliver all food from -2,0
in excess of 384 units to -3,-1.
.s1
.EX deliver lcm -2,0 b
This command will deliver all lcm's from -2,0 to -3,1.
.s1
.EX deliver lcm -2,0 +30
This command will deliver lcm's in excess of 24
(deliver uses multiples of eight).
.s1
.EX cutoff -2,0
This command will report what commodities are being delivered
from -2,0 and what their cutoffs are.
.s1
.EX route food -20:20,-10:10
This command will graphically report the food delivery paths
in the sectors from -20:20 to -10:10.

\*(iFSome More Hints for the Novice\*(pF
by Jeff Trim
.s1
Tech levels are very important in this game.
You cannot produce uranium, guns or shells
until you achieve a tech level of 40.
.s1
Choose your friends carefully.
I was talking to Lewis from Cornell College
and his comment was the best I'd heard in a while:
\*QNever ally with someone that doesn't have a definite
interest in seeing you survive.\*U
Don't be deceived by the treaty command;
treaty violations will show up in the news,
but that is not going to stop the aggressor from wiping you out,
no matter how bad it looks in the news.
.s1
Nuclear attacks can cause a lot of damage,
but no one has ever been taken out of the game by a nuclear attack.
The damage from a purely nuclear attack is recoverable.
It takes conventional forces combined with nukes to really do damage.
(Of course I won't fool you either;
it doesn't hurt to have a few nukes either.)
.s1
Beware of running low on BTU's.
I will recount one story of a player on this site
that was running low on BTU's.
His enemies launched a nuclear attack and hit his capital!
Unfortunately, he didn't have enough BTU's
to redesignate a new capital.
The moral of the story is that you should
plan an alternate capital at some point in the game.
These are generally not needed at the beginning of the game,
because you need to effectively deploy your sectors in the early going.
But later, it wouldn't hurt to have one or more alternate capitals.
.s1
Empire is a game of perception.
If your adversaries think you're tough,
they're probably going to pass you and head for easier prey.
But the reverse is also true;
if you look weak they might try a few tactics on you --
and depending upon your response,
they'll either back down or fight it out.
Bargain from a position of strength.
You could be the weakest country on the planet but still look
so tough that no one would bother you.
It's all perception.
.s1
Weak countries have an added advantage: gun running!
If a country is heading out with his fleet
to attack another country and you happen to be along the way,
you could cut a deal with him and
you could make a deal and allow that country to attack a coastal
sector and turn it into a harbor.
You've now placed an obligation on that country,
who will be very careful to keep you happy so you won't
grant similar privileges to that country's enemy.
Weak nations can be quite powerful if you handle the diplomacy right.
The tough players like blowing away their tough adversaries
and as long as you stand idly by
and watch those two countries blow each other to little pieces,
you'll be left intact and growing richer off their little war.

.NA Overview "An Overview of the Game"
.LV Basic
What is Empire?
.in +0.3i
.s1
Empire is an military/economic simulation of make-believe
countries in a make-believe world.
The military part is emphasized.
The economic part is still there,
but as a prerequisite to a working military.
.in
.s1
What part do I play?
.in +0.3i
.s1
Each player is the ruler of a country.
As leader of your country,
you give commands that affect your country
(e.g., move people around,
re-designate sectors, etc).
You also handle all of your country's foreign policy.
.s1
Empire lets you get reports on the status of your country
(``info census'' and others),
find out what's going on in other parts of the world
(``info news''),
and communicate with other countries
(``info telegram'').
.s1
Although no goal is explicitly stated,
most players rapidly derive their own,
ranging from the mundane desire to be the biggest,
strongest country in the game,
to the more refined goals of
having the most efficient land use possible,
or having the lowest ratio of military to civilians while
still surviving.
.in
.s1
The World of Empire
.in +0.3i
.s1
Empire is played on a hexagonal map
partitioned into a rectangular grid of \*(iFM\*(pF\ \(mu\ \*(iFN\*(pF
sectors (where \*(iFM\*(pF and \*(iFN\*(pF are typically,
but not necessarily,
powers of two, usually 64, 128, or 256).
The world is made up of approximately
50% sea, 45% habitable land and 5% uninhabitable mountains.
.s1
Sectors can be assigned a specific sector type.
These types range from banks to nuclear fuel processing plants.
See ``info Sector-types'' for more detail.
.s1
Your personal coordinate system is based on your capital,
which is a type of sector.
Your capital is generally marked by the coordinates 0,\ 0.
.in
.s1
The Empire Time Scale
.in +0.3i
.s1
The Empire world both does and does not match the real-time world.
To better explain this, let us examine the concept of an update.
.s1
At regular intervals (usually once per day),
the entire Empire world is updated.
When the world updates, new population is added,
ores are dug up and added to stockpiles,
food and other commodities are distributed to sectors,
the educational and technological levels are updated,
and so on.
It can be thought of as the minimum quantum for growth.
.s1
On this time scale, an update could be considered
to be approximately one generation.
Thus the difference from the time scale of the real world.
.s1
However, certain commands are issued in real-time,
such as attacks.
These commands have instantaneous effects on the state of your country.
Dedicated (or merely experienced) Empire players will often
log on to monitor their country.
And most attackers will wait until the small hours of the morning
to carry out their attacks, for obvious reasons.
.s1
If you do not log in to Empire,
any automatic policies you have set up will be carried out.
However, Empire will not try to fix any mistakes you have made;
unless you are very careful,
it's probably not a good idea to rely on these automatics.
.in
.s1
Bureaucratic Time Units (BTU's)
.in +0.3i
.s1
To prevent the more fanatical Empire players
from staying logged on all the time,
Empire places a limit on the amount of time you may be logged in
per day.
This limit is settable by the deity, usually 1000 minutes.
If you run out of time, too bad!
You can't log in again until the counter resets itself
(usually at midnight).
.s1
The other control on the number of commands that you may issue
are called ``Bureaucratic Time Units'' or BTU's.
A BTU is an arbitrary amount of bureaucratic bookkeeping that
your government must spend to perform a certain function.
Most commands that are not merely informative cost BTU's.
.s1
BTU's are generated by your country's capital.
The more efficient your capital, the more BTU's that are generated.
The number of BTU's also depend on the game's settings.. See the 
output of the 'version' command for an estimate of BTU generation speeds.
However, you may have a maximum of 512 BTU's at any one time.
And once your BTU's reach zero, you may not issue any commands
that use BTU's.
.s1
Three things to note about BTU's:
.in +\w'00)\0\0'u
.s1
.L 1)
Since commands use up BTU's,
this limits the number of commands
that a player may issue over a particular time period.
This has the effect of preventing the Empire fanatic
from overruning other players with less free time to log on.
.s1
.L 2)
The build-up of BTU's is constant and does not depend on being
logged in.
This allows players to participate when it is convenient rather
than at some fixed time
(such as most board games, or the stock market).
.s1
.L 3)
The BTU concept helps compensate for the fact that,
in concept, the governments of each country are always
``playing'' although the player representing that country
may only log in periodically.
.in -\w'00)\0\0'u
.in 0
.s1
How long will a game take?
.in +0.3i
.s1
Probably from one to four months.
You should expect to spend one to four hours a day playing.
Also expect that if you do spend this amount of time playing,
your grades or work will suffer.
You just can't spend that much time playing and either
study or be productive.
.in
.s1
What should I do now?
.in +0.3i
.s1
When a new country enters the game,
it starts out with an amount of money and two sectors.
These sectors are sanctuaries
and have an initial amount of people and commodities.
Until you \*Qbreak sanctuary\*U,
your country is effectively in stasis.
Nothing will change until you actually log in and
force a change
(such as designating a capital to begin accumulating BTU's).
.s1
The absolutely minimal set of information pages you should read are:
break, map, ann, wire, tel, read, expl, move, res, cen, dist, thresh, lev,
com, prod, budget, Sector-types.
.in
.s1
A Comment from Peter S. Langston (the author of the original Empire game)
.in +0.3i
.s1
It should be remembered that Empire is merely an interesting pastime;
in the vernacular, \*Qit's just a game\*U.
There are many amusing stories of people
that took the game too seriously;
one tells of a corporate Vice President
who walked into the computer room and flipped the main
circuit breaker in order to stop an attack on his country;
another tells of the Harvard student
that refused to go to bed until everyone logged out of Empire
and of the other players who took turns staying up late....
.s1
While many players take Empire very seriously,
an equal number of players use it as a safe environment
in which they can act out their fantasies.
On occasion the fantasies involved are remarkably aggressive or hostile.
It has been my experience that the people with the most belligerent
countries are often the people with the kindest hearts;
anti-social game play doesn't necessarily reflect the \*Qtrue\*U
being underneath
(or else I have some VERY weird friends).
.in
.s1
A Brief History
.in +0.3i
.s1
The game \*QEmpire\*U is the most recent in a series
of territorial conquest, political/economic simulation games
initially inspired by a board game of the same name
played at Reed College (Portland, Oregon).
Earlier versions were written at Reed by Peter Langston
and at The Evergreen State College (Olympia, Washington)
by Chas Douglas, Peter Langston, Ben Norton, Mike Rainwater and others;
of particular note are the games \*QGalaxy\*U (Langston)
and \*QCivil\*U (Norton).
The previous version was written in 1985 partly on the HRSTS Unix system at
the Harvard Science Center, (Cambridge, Mass.),
partly on the Unix system at Commercial Union
Leasing Corporation, (New York, N.\ Y.)
and partly on the Unix system at Davis Polk & Wardwell,
(New York, N.\ Y.)
by Peter Langston with invaluable goading from
Joe Stetson, Robert Bradbury, Nat Howard, Brian Redman, Adam Buchsbaum,
and a myriad of others.
Since Langston never released source code for his version,
Dave Pare and friends de-compiled it in that same year and have
created this version
which is very different.  Since then many re-writes and fixes have been
put in and none of the original code exists anymore.
Many people have enhanced the
code, most notably, Dave Pare added plane units in 1986, Jeff Bailey
added many configurable options in the KSU distribution, Thomas
Ruschak added land units and missions in 1992-1993 and released the
"Chainsaw" server, and Ken Stevens rewrote much of the server code in
1995 and released the "Empire2" server, and Steve McClure and the Wolfpack 
made lots
of other changes and released the "Empire4" server in August of 1996.

.NA Suggestions "Suggestions for enhancements to the game"
.LV Expert
.nf

	Whenever I think about new things for empire, I evaluate them in this
order:

		1) Is it fun?

	This is subjective, of course. The real question should be "Will the
majority of Empire players find this enjoyable?"

		2) Is is complicated?

	What sorts of new commands are needed? How will the player use the new
feature? Do new commands need to be added? How much will this change impact
the user?

		3) Is is code-able?

	How difficult is it to do? Does it involve minor changes, or a major
re-write? Many ideas have merit, but are prohibitively difficult to implement.

		4) Is it realistic?

	In general, realism is good, in that it makes the game more intuitive,
and easier for new players to learn.

	        5) Is it play-balanced?

	It is important that the delicate balance between offense and
defense not be tipped one way or the other.  For example, a stacking
limit for land units would tip the balance too far in favour of the
defender.  Or, allowing more than one ship to assault at a time would
tip the balance in favour of the attacker.

		6) Is it important?

	If the change involves adding detail to the game, is the detail 
important enough? Does the change go beyond the general level of Empire
abstraction? For example, a change to allow you to name each of your mil
would obviously be beyond Empire's general detail level. A command to name
ships is stretching it.

.LV Expert
.s1
NOTE: This file is dramatically out of date.
.S1
The classification scheme used by report is dumb.
.s1
You can make a sector temporarily useless by filling up all its
fields with delivery and distribution information.
This is useful when an enemy is trying to capture the sector
(his mil don't have room to move in :-)
You have to halt some of the deliveries or distributions
to make room for the military to move in.
(Mostly fixed by changing the number of available fields)
.s1
Warehouses can't distribute all commodities simultaneously,
due to limited fields for this information.
This becomes a problem if you have a countrywide network
of warehouses distributing to each other.
(Mostly fixed by changing the number of available fields)
.s1
You can sometimes build planes in non-airport sectors,
deliberately or accidentally. FIXED
.s1
You can sometimes move small quantities of certain items
from warehouses at no mobility cost, even into mountains
(this is my favorite bug, I'd hate to see it fixed :-)
.s1
Guerrillas don't seem to carry the plague.
.s1
You can get information about enemy sectors
by attacking with 0 military.
This costs 0 BTU's currently
(this is another of my favorite bugs :-)
This is a good way to flood the enemy mailbox with junk mail
at no cost in BTU's. FIXED
.s1
You can sometimes trick someone into paying a huge price for
commodities by changing the price suddenly.
Therefore one should always check prices when buying commodities.
.s1
When two countries are attacking each other simultaneously,
you can sometimes move into a sector he is in the process of attacking.
If you get the timing right,
he will take the sector but you will get it back,
along with all his military.
.s1
If a plane is out to trade, and gets shot down,
it can still be bought until the next update.
If another country builds a new plane
that gets the number of the plane that was shot down,
the new plane will go on the trading market automatically.
Then if that plane is bought,
the money goes to the country whose plane was shot down,
not the country that built the plane.
I stole numerous planes
(including nuclear missiles :-)
this way
(by deliberately putting low numbered planes up for trade,
then having them shot down).
.s1
If a plane has negative mobility, then gets traded, mobility
goes to 0.
.s1
Firing on sectors with land-locked sunken ships does strange things.
.s1
If two countries are cooperating,
its possible to raid an enemy airport and steal the planes
by putting them out to trade.
.s1
You can also strip enemy sectors of commodities using \*Qsell\*U,
if you have military control temporarily.
.s1
One can raid an enemy harbor and use up all the raw materials
by building useless ships. FIXED
.s1
One can make work go back to 100 everywhere in a country by
moving all civilians in low-work sectors onto a bridge,
then collapsing the bridge.
Work then goes to 100 at the next update,
if you leave some mil in the vacated sectors.
Or you can move mil out too,
letting the sector ownership change to the Deity,
then move back in from a 100% working sector,
and work goes immediately to 100.
.s1
Two cooperative countries can move commodities around at no
mobility cost using the market.
.s1
You can depopulate an enemy sector in a raid by converting
all civs to uws and selling them.
This can make it hard for the victim to get back in the game
even with a rapid & successful counterattack. FIXED, convert takes mob now.
.s1
Sometimes sector ownership doesn't change when the last civ starves,
so you may get census information about sectors with 0 civs.
Later this same sector may get its ownership
switched to the Deity without your doing anything. FIXED
.s1
You can only have so much of a commodity in a sector.
If you went over 32,000 and something, units of food, for example,
bizarre things might happen.
I think that has been fixed. FIXED
.s1
Treaty had bugs
(for example, firing on any ships was considered a treaty violation,
not just the ships of the country you had a treaty with).
I think Jeff might have fixed this. FIXED
.s1
Also air attacks were not considered treaty violations.
This may have been fixed. FIXED
.s1
You can collapse enemy bridges by making a lightning raid on
his bridgeheads and redesignating them,
even if you only hold the bridgehead for a short time.
(In this games, bridges work differently, see info build, info bridges")
.s1
You can map out enemy territory by raiding his radar stations.
.s1
Condition checking is very treacherous.
Global commands with conditions are unreliable.
I never figured out exactly what was wrong,
although I think your method of putting conditions
towards the front of the line helped sometimes.
.s1
You can have more than 26 ships in a fleet,
but only the first 26 will move when you navigate the fleet
(I think 26 is the right number, but I'm not certain.
It might be 32).
.s1
\*QLook\*U only spots subs (from destroyers) at a certain distance.
If you are too close you won't see them
(unless you are in the same sector).
.s1
You can only fly as many planes on a mission as
you can fit on the command line
(so low numbered planes have an advantage this way).
USE WINGS
.s1
I never managed to load more than 1 warhead on a missile,
but I didn't have time to investigate this thoroughly. FIXED
.s1
Wilderness sectors that you own don't appear as \*Q?\*U on enemy maps,
so you can sometimes hide information by leaving sectors
as wilderness. FIXED
.s1
When a sector has a visible ship,
radar doesn't show whether the sector is land or sea, just the ship.
This has interesting possibilities for exploitation
(like land-locking a battleship
in your capital in order to deceive the enemy :-)
.s1
I don't think you can land planes on a land-locked aircraft carrier
anymore.
.s1
Its common to mistakenly set the price of a plane or ship incorrectly
so one should check trade after using set.
.s1
Torpedo isn't random, but always works within range
(another of my favorite bugs :-) FIXED
.s1
Transporting nukes costs 0 mobility. FIXED
.s1
The \*Qmust be accepted by\*U date on offered loans is bogus.
.s1
\*QTurn off\*U doesn't stop updates.

Changes to the Chainsaw code in version 1.0
.s1
This file enumerates some of the more important changes between
BBN Empire 1.0 & BSD Empire 1.1.5, KSU, & MERC empire. BBN Empire 1.0
is a superset of the other versions, including all MERC code, which includes
all KSU code, which include the BSD 1.1.5 code.
.s1
.L Bug-fixes & Changes
.s1
Scrap and scuttle will now ask for confirmation before scrapping or scuttling
wing or fleets. The will also ask before scrapping or scuttling ALL planes or
ships (when a '*' is given as an argument)
.s1
Bomb has been changed to allow planes with the P_T (tactical bomber) flag to
bomb, even if they are also cargo planes. This fixes the problem with Zeppelins
not being allowed to bomb.
.s1
Power has been modified to not report on all deity countries (as opposed to just
ignoring country 0)
.s1
The plane functions have been extensively modified to calculate and enforce
the ship plane-capacity limits. In previous versions, this was enforced only
in the load command, and incorrectly maintained. (In some situations, the #
could go negative, and wrap around to 255, causing much disbelief)
.s1
The telegram command was changed so that bulletins from a deity include the
name of the deity country that sent them. (Useful for multiple deity games)
.s1
The nation files are re-read for the report and country commands. Before,
the program would use the in-memory nation stuff, which meant that it was out
of date if it changed (i.e. people logging in/out after you would not be shown
as logged in in the country output, report would be out of date, esp in blitzes,
etc) With this option, the nation file is closed and re-opened, which updates
the in-memory stuff to be current. This is still not perfect, as when people
exit incorrectly, they are still shown as logged on, until they telnet and
kill the process, or the transaction manager is restarted.
.s1
Also, the init_nats function was changed. Previously, if a country did not
receive a BTU delta when logging in, its last login time was not set.
.s1
.L OPTIONS
.s1
Many new options have been defined for BBN 1.0.
.s1
.L CHOPPER-STEALTH
.s1
Choppers have a chance of evading interception. It isn't as good as
stealth, which is why it's listed as half-stealth. I'm not telling
the exact numbers... figure them out for yourself.
.s1
.L BABY_NUKES
.s1
Credit for this idea goes to Tom Tedrick. Damage/effects are the same,
but blast effects are confined to the target hex. This also automatically turns
of MISSING MISSILES. Note that launch will still ask about air/ground burst.
.s1
.L SUPER_BARS
.s1
Gold bars cannot be pin bombed, and are not hurt by firing. There are still
ways to kill them, but not by shelling or bombing.
.s1
.L EASY_BRIDGES
.s1
A bridge can be built in any sector adjacent to one of yours, providing
that the target sector is adjacent to a non-sea, non-bridge sector. Since
bridgeheads are not required, you can't collapse bridges by killing the head.
(You can still kill them by taking the bridge below 20%) This also fixes a 
problem with planes on bridges not dying when the bridge dies. (This was partly
fixed before, but the fix didn't work all the time)
.s1
Note that the sector building the bridge may be a bridge, providing the sector
that the bridge is being built in is adjacent to a non-sea, non-bridge sector.
For example, this is legal:

 . . . . . . .	=>	 . . . . . . . 
. . . . . . .	=>	. . . . . . . 
 . - = . - . .	=>	 . - = = - . . 
. . . . . . .	=>	. . . . . . . 
 . . . . . . .	=>	 . . . . . . . 

.s1
This is not legal:
 . . . . . . .	=>	 . . . . . . . 
. . . . . . .	=>	. . . . . . . 
 . - = . . - .	=>	 . - = = . - . 
. . . . . . .	=>	. . . . . . . 
 . . . . . . .	=>	 . . . . . . . 

.s1
Also, the sector building the bridge must be at least 60% efficient.
.s1
.L BETTERARMOR
.s1
Ship's armor factors now more greatly affect both shelling and bombing. BB's are
much harder to kill. Smaller ships are more fragile.\
.s1
.L ALL_BLEED
.s1
When this option is enabled, countries receive tech leakage from ALL tech
producers, not merely allies. Tech leakage is 33% by default. The leak is
calculated as 33% of the average tech made by all those making tech. For
example, if there are 10 players, making 3, 4, 0, 0, 3, 0, 2, 0, 2, 1 tech,
the total tech made is 15 by 6 countries, for an average of 2.5 tech. All 10
countries would get .833 tech leak (33% of 2.5), for total tech production of:
3.833, 4.833, 0.833, 0.833, 3.833, 0.833, 2.833, 0.833, 2.833, 1.833
.s1
.L DRNUKE
.s1
You need research to build nukes. (1/4 the tech value, so a tech 300 nuke
needs 100 research)
.s1
.L SLOW_WAR
.s1
You cannot attack someone's land unless you are at war with them. (You can
still blow up their ships with fire, board, torp, etc) When you declare war on
someone, your relation goes to Mobilizing. You still can't attack them. After
the next update, your relation goes to Sitzkrieg, and you still can't attack
them. After the NEXT update, you're at war with them, and anything goes.
.s1
If someone is Mobilizing or in Sitzkrieg, or At War with you, and you
declare war against them, your relation is set to be the same as theirs, so
there is no way to gain any advantage through this stuff. It just means that
you can't sneak-attack people.
.s1
The restrictions do not apply if you are the old_owner of the sector. If you
are the old_owner, you may bomb/shell/attack at will.
.s1
Note that while ships are freely attackable, regardless of war status, even
if they are in a harbor of a nation you are not at war with.
.s1
The first person who declares war pays $1000. Return declarations are free.
.s1
.L NOMOBCOST
.s1
Ships do not use mobility when firing. Torpedo mobility cost is reduced to be
equal to 1/2 the mobility the firing ship would use to move a sector.
.s1
.L NEWSUBS
.s1
This option encompasses several small changes in sub-warfare. A new flag, sub-t,
is added. Only ships with the sub-t flag are allowed to torpedo subs. Also,
ships with depth-charge capability can now use them to their full gun range.
Depth charges are more affected by sub armor value. Torpedo damage is increased.
.s1
.L OTHER-CHANGES
.s1
Most of the ships have had their firing ranges bumped up significantly.

CHANGES.CHAINSAW.2.0
.s1
Changes to the Chainsaw code in version 2.0
.s1
This file enumerates some of the more important changes between
the code used for BBNII (Chainsaw Empire 1.0) & Chainsaw 2.0.
.s1
.L Bug-fixes
.s1
You can no longer map by attempting to land planes on unknown sectors.
The replies have been standardized to give no information.
.s1
The radar command is fixed to eliminate 'ghost' images at high tech.
.s1
Planes can now land on carriers that happen to be in bridge sectors.
.s1
You can no longer find out if any enemy subs are under your bridges by
trying to load things on them.
.s1
You can no longer load things onto non-allied ships, even
if they are in a harbor you own.
.s1
'break' now breaks ALL sanctuaries you own, even if some are not adjacent
to 0,0.
.s1
When specifying a flight path, the terminating 'h' is no longer counted as
a sector for purposes of range.
.s1
Qorder is now documented, and works as described in the document.
.s1
.L CHANGES
.s1
When scrapping or scuttling groups of ships/planes or wings of
ships/planes, you will be asked to confirm that you want to do it.
(Also when doing scrap * or scuttle *)
.s1
Ships that assault will always retain 1 food.
.s1
You may now specify a "number to build" parameter for build.
.s1
The deity can now make declaration on another country's behalf.
.s1
Minesweepers now take less damage from mines (1/2 the normal amount).
.s1
A plane unloaded in an ally's harbor now becomes his plane. A plane loaded
onto an ally's ship also becomes his plane.
.s1
Your planes may now land on an ally's sectors or ships. Once there, they become
his planes.
.s1
Ships will fire back in defense of sectors being attacked,
assaulted, or shelled.
.s1
Your ships/sects will no longer shoot themselves in defense.
You can cheerfully blast your own ships/sects without fear of
retaliation from your own forces. You can also torp your own 
ships, and they will resignedly watch as the torps slam into them.
.s1
Gun ranges are no longer truncated. Instead, there is a % chance equal to the
decimal portion of the range of gaining a hex. For example, with a range of
2.50, there is a 50% chance of being able to fire at range 3. With a range of
6.33, there is a 33% chance of being able to fire at range 7.
.s1
The power report has been changed to be more realistic. The relative worth
of most commodities has been changed, and a country's total is multiplied by
a tech factor to arrive at a final value.
.s1
There is no longer a minimum maintenance cost of $1/ETU for planes and ships.
The new minimum is $1.
.s1
The torpedo command is changed. Surface ships may now have the torpedo ability,
as well as subs. When surface ships torpedo, they are fired at by defending
ships BEFORE they fire their torpedos.
.s1
An "escort" flag was added for planes. Planes with the escort flag may escort
missions. (Formerly, only planes with the intercept flag could escort)
.s1
Fighter aircraft being used as tactical bombers are now at a greater penalty
in air-to-air combat.
.s1
Ships with no mobility may now be nav'd. This allows fishing boats and oil
derricks to check resource values without having mob. (Of course, you can't
move with no mob, and an attempt to do so kicks you out)
.s1
The load command will now allow you to load wings/groups of planes.
.s1
You may now give things to allied ships using the tend command. (You may not
take things from allied ships, only give) (If ALLYHARBOR is used)
.s1
You may now upgrade allied ships. (If ALLYHARBOR is used)
.s1
Your civs will work on allied ships in your harbors. (If ALLYHARBOR is used)
.s1
You may assault your own sectors. Mil assaulting are simply added to the 
number in the sector.
.s1
You may now land planes on a carrier in an allied harbor. (If ALLYHARBOR is
used)
.s1
Conventional non-tactical missiles will now be intercepted by ABM's.
.s1
.L Options
.s1
.L Trade-Ships
.s1
Trade ships simulate internal or external trade. In the real world, you make
goods someplace where they're cheap, ship them somewhere they're expensive, and
sell them, making a profit.
.s1
For empire purposes, you make a trade ship, which uses many cm's, and costs
$2500. You then sail it somewhere and scuttle it. You get money back, more than
you put into building the ship. The return rate depends on several factors.
.s1
The primary factor is distance. The distance is calculated as straight-line
distance from the sector the ship is scuttled in to the sector in which it was
built. You have to sail it at least 8 sectors to get any profit at all. If you
sail it more than eight, the profit rises steadily.
.nf
		dist < 14:	+3.5% * dist
		dist < 25:	+5.5% * dist
		otherwise:	+7.5% * dist
.fi
.s1
Another factor is the sector in which you scuttle it. If you scuttle it in a
harbor you own, you get normal cash. If you scuttle it in the harbor of
an ally, you get a 20% bonus, AND your ally gets 10% of the cash you make as
a bonus (you still get the full amount)
.s1
For example, using the numbers from above, if you sailed 15 sectors, and
scuttled in an allied harbor, you'd get $4562 * 1.2 = $5.5K, and your ally
would get $4562/10 = $456.
.s1
The last factor is the efficiency of the trade ship. The cash return is
multiplied by the efficiency of the ship when it is scuttled.
.s1
Note that captured trade ships can be scuttled by pirates, who receive cash
as if it was their own.
.s1
.L FUEL
.s1
Each ship has a fuel capacity, and a fuel usage rate. During an update, ships
use fuel at a rate of 10 mob for every  units of fuel. Ships with
a fuel usage of 1 get 10 mob for every 1 fuel, ships with 2 fuel usage get 10
mob for 2 fuel, etc. Ships with no fuel do not get mobility. Ships with a fuel
usage of 0 do not need fuel. (Sailing ships & nuc ships/subs)
.s1
A new command, "fuel" is added. It allows fueling from a harbor sector, or a 
ship or ships with the "oiler" flag. When fueling, petrol and/or oil in the
harbor or on the oiler is exchanged for fuel points, which are loaded on the
ship. Petrol is used first, if available, at a rate of 1 pet = 10 fuel. If
there is not enough petrol, oil is used, at a rate of 1 oil = 50 fuel.
.s1
Ships of allies can be fueled, if the ALLYHARBOR option is in use, either at a
harbor, or with an oiler.
.s1
.L SEMILAND 
.s1
This option adds a flag, "semi-lander", which allows the ship to use 25% of its
mil in an assault.
.s1
.L SHIPCHOPPERS
.L XLIGHT
.s1
These two flags are similar. They establish new plane flags, "helo" (ship
helicopter), and "x-light" (extra light). Each ship is then rated on it's
ability to carry those types,
independently of it's ability to carry normal planes. This allows deities
to let non-carriers carry sams, for example, or to let ships carry anti-sub
helicopters or transport helos.
.s1
.L ASW_PLANES
.s1
A new plane flag is added "asw". This allows planes with the flag to spot
subs on recon missions. (Detection chance is
(100-accuracy)-(4-sub visibility)*10)
Planes with this flag may be informed (depending on detection ability) when
pin-bombing a sea-sector of the presence of subs. They then have the option of
bombing the subs. Each plane on such a mission rolls separately to find the
subs, and can only bomb the ones it can find.
.s1
.L PARAFLAG
.s1
A "para" flag is added for planes. Only planes with the para flag can be used
to paratroop.
.s1
.L STEALTHV
.s1
This option adds a new statistic for planes, stealth percentage. Use of this
option effectively disables stealth planes and the CHOPPER_STEALTH option, as
the stealth and half-stealth flags are ignored.
.s1
With this option, each plane is rated as to its percentage chance to evade
ground-fire and interception. The stealth rating of a group of planes is equal
to the rating of the plane in the group with the lowest stealth rating.
.s1
.L MULTIFIRE
.s1
When this option is used, both fire and torpedo accept multiple ships/sectors.
Each firing ship/sector may be used against a separate target, or all may fire
together.
.s1
Return fire is distributed evenly over the firing ships/sectors, with each
defending ship/sector firing once. The spreading of damage also applies to
subs being depth-charged after torping, and for torpedo boats being fired at
prior to torping.
.s1
.L RETREATS
.s1
Each ship/fleet may be given a retreat path, and retreat conditions. Conditions
are: retreat when damaged at all, retreat when torped, retreat when sonared,
retreat when fired upon from beyond max range, retreat if bombed, retreat if
depth-charged.
.s1
Retreat conditions are assigned to ships, and may be assigned to entire fleets
at once. When a ship's retreat condition is satisfied, things happen.
.s1
If the ship's fleet has a retreat path, all ships in the fleet that are in the
affected sector attempt to retreat 2 sectors along the path, using mobility as
if they were navigating.
.s1
If the ship's fleet does not have a retreat path, then the ship checks to see
if it has it's own retreat path. If so, it retreats 2 sectors along it, as
above.
.s1
Note that retreating ships can hit mines, and could be blocked by new bridges,
or by an ally changing to non-allied status (which would make them unable to
retreat into a harbor)
.s1
Retreat paths are wiped from a ship when the ship moves. Retreat paths are wiped
from fleets only at the player's request.
.s1
.L HARBOR_POLICE
.s1
With this option, the board command is extended to allow boarding of enemy
ships in your harbors. The harbor sector must have mobility, but the command
does not use any mobility.
.s1
.L MINE_PLANES
.s1
With this option, planes with the \*Qmine\*U ability are allowed to use
the drop command to drop shells as mines in sea sectors. (see info drop)
.s1
.L SWEEP_PLANES
.s1
With this option, planes with the \*Qsweep\*U ability will automatically
attempt to sweep mines while on recon missions. See info recon for more
details.
.s1
.L BUDGET
This option changes the update ordering a bit, and allows you to set
priorities for production, for those situations where money is tight.
A new command, \*Qbudget\*U, is added, that shows financial information,
and allows setting of priorities.
.s1
.L DAVYJONES
.s1
When this option is used, nukes striking wasteland or sanctuary sectors do
not detonate. Nukes striking water sectors affect only their impact sector.

.s1
Thanks go to all the people who've helped me with ideas and playtesting:
Jorge Diaz (Ansalon), Tom Tedrick (Afrika Korps), Keith Graham (DreamLands),
Dave Nye (Evil_Empire), Sasha Mikheev (Dolgopa), Baldric, Elsinore, Brett Reid
(Resvon), Kazzadur \ystein Tvedten (Flipper's evil twin), Tharkadia, Yikes, and
many more I'm forgetting. The good things are mostly ideas contributed by these
people. The bugs, I'm afraid, are my own.

CHANGES.CHAINSAW.2.1
.s1
Changes to the Chainsaw code in version 2.1
.s1
Chainsaw 2.1 has some minor differences from Chainsaw 2.0.
.s1
Now, when navigating, sonar or radar commands will
default to the current ship, or the first (lowest 
numbered) ship in a group. You may override this by
specifying the desired ship on the command line.
(I.e. "r 12" or "radar 212", etc)
.s1
The chance of a plane aborting is changed to 
(100-eff)%. This means that if a 100% plane
takes a hit for 30% damage, it has a 30% chance to abort.
If it then takes another hit for 20% more, a total of 50% damage,
it has a 50% chance to abort.
.s2
Also, when bombing ships, rolls are not made for
aborting until after all ships have fired, rather
than rolling every time the plane takes a flak
hit from a ship.
.s1
A new command has been added, the 'payoff' command. 
It shows the value of trade ships if scuttled at
the current sect (check info payoff).
.s1
Constants have been added to control ship & plane 
efficiency growth rate. It is now possible to allow
2xETUS growth in efficiency, 3x, etc.
.s1
Subs may no longer shell.. they may only torpedo.
.s1
A WIRE option has been added that activates the
'wire' command. The wire command reads only
announcements. The normal read command then
reads only telegrams & bulletins.
.s1
When assaulting, troops will always leave at least 1 food on the ship.
.s1
You may now build multiples of an item by adding a build count at the 
end of your build command. (see info build)
.s1
You may now give comments in the hours file. Comment lines start with a
'#' character. (Players do not need to care about this.. it's for deities)
.s1
The report command has been changed to not include countries
that are not active. (i.e. visitor or in sanctuary)
.s1
The version command now show the ship/sector/plane mobility max/gain,
as well as the ship/plane growth constants.
.s1
CHANGES.CHAINSAW.2.2
.s1
Changes to the Chainsaw code in version 2.2
.s1
Chainsaw 2.2 has some minor differences from Chainsaw 2.1.
.s1
A new option, SNEAK_ATTACK is included. It can only be used in
conjunction with SLOW_WAR. It allows you to attack a sector of
someone you're not at war with. Once attacked, the attacker 
automatically declares war against the defender, and pays $5K.
At that point, the attacker has to go through the normal SLOW_WAR 
procedure before attacking again. See info attack, info assault.
SNEAK_ATTACKs may not be done by parachute.
.s1
The 'list of commands' command now puts a 'c' in front of commands
that require you to have a capital to use, and a '$' in front of
commands that require you to be non-broke for use.
.s1
CHANGES.CHAINSAW.3.0
.s1
Changes to the Chainsaw code in version 3.0
.s1
Chainsaw 3.0 has some major differences from Chainsaw 2.2.
.s1
Ships that don't carry enough crew lose effic when at sea. See
info build (the ship building section)
.s1
The BUDGET option has been removed. Budget is now standard.
The NEWSUBS option has been removed. NEWSUBS is now standard.
The MULTIFIRE option has been removed. MULTIFIRE is now standard.
.s1
I took out the 'too much traffic for workers' thing, because it was dumb.
.s1
Ships of tech 310 or better can detect mines with sonar.
.s1
Conventional missiles launched from subs are anonymous. The
victim is not notified of the launching country's identity,
and the news knows naught.
.s1
In order to export something from a sector, you must have
military control of the sector. In order to import something from a
distribution sector, you must have military control of the distribution
sector.
.s1
The chances to hit a mine are changed. See info mine and info lmine.
.s1
Two new deity commands have been added, 'disable' and 'enable',
which disable and enable updates. The 'update' command will mention
it if updates are disabled.
.s1
When you capture a sector, all distribution info is wiped (distribution
sector, thresholds).  Sectors just taken over are stopped (see start and stop).
.s1
The criteria for sector ownership have been changed slightly. See
info sector-ownership for information.
.s1
Countries still in sanctuary can now get telegrams and announcements.
.s1
Fishing boats and oil derricks only work in open ocean sectors.
.s1
Civs & mil may be distributed. No sector will export its last civ.
.s1
A new command, bdesignate, has been added. It allows you to manually
modify your bmap.
.s1
When navigating a ship or marching a unit, you get a map of the sectors around
your ship or unit, without using BTU's.
.s1
When using map or bmap, giving the number of a ship you own instead
of an area will give you a map centered around that ship. For example,
.s1
.EX map 1
.s1
will give you a map centered on ship 1. Lmap works similarly, except
you can get a map around a land unit, and pmap gives a map around a plane.
.s1
When loading/unloading, you can give a desired level as a negative number
instead of an amount to load/unload. For example:
.s1
.EX load 4 -10 food
.s1
will attempt to load or unload food as necessary to get ship 4 to 10 food.
(Similar to the syntax for enlist) See info load for details.
.s1
Land units have been added. There are many new commands for dealing with them.
Look at info Land-units for a general overview.
.s1
Sectors that don't have enough food at the update will now attempt to 
draw food from supply sources. (see info supply for details on supply sources.
Conquered sectors will not draw food)
Other sectors/ships/units will now draw supplies (mostly shells) when they
need them.
.s1
You can now give destination sectors instead of paths for all movement
commands. For example,
.s1
.EX move c 0,0 10 5,-1
.s1
will move 10 civs from 0,0 to 5,-1 via the most efficient path, the
one that uses the least mobility.
.s1
Ships/planes/units now use lcms/hcms as they gain efficiency, rather than using
them all at once. See info build for more details.
.s1
Distribution has been changed. Each sector now has a distribution sector
rather than a distribution path (during the update, the least-cost path
is found and used) Also, importing & exporting via distribute now happen
in separate  phases, rather than being mingled. See info distribute 
and info update-sequence for a full description.
Read info distribute, or don't cry.
.s1
There is a document that details the update sequence. (info update-sequence)
.s1
Civs/mil/uw's are much harder to kill (how much harder is deity-settable)
with shelling or bombing or nuking.
.s1
Air to air combat is changed. Check info interception for an explanation
of the interception process and a description of air combat.
.s1
Fully efficient roads now have a small mob cost to move through.
.s1
Fort gun range is now (7*tech factor). Damage from fort shelling now
depends on the number of guns firing. Forts get a +1 range bonus if at
least 60% efficient.
.s1
Sectors can cost money to designate, and may cost extra to build. They
may also take lcms or hcms to build. Show sector build will show this.
.s1
A new command, cede, allows you to give a sector or ship to a neighbor. See
info cede for more details.
.s1
There are several new information commands, such as neweff and 
starvation. See the info pages for details.
.s1
Sectors are damaged by combat occurring in them. See info attack for details.
.s1
Missions may be given to ships/planes/units, allowing them to interdict 
enemy movement, support friendly attacks & defense, and other things.
See info mission for details.
.s1
Forts automatically fire at enemy ships coming within range.
.s1
Mountains can be used (poorly) as capitals. See info capital.
.s1
New options:
.s1
RES_POP: when RES_POP is enabled, the maximum number of civilians, mil,
or uw's that can be in a sector is determined by research. See info
research for exact details.
.s1
NEW_STARVE: when NEW_STARVE is enabled, the starvation ordering is changed.
Instead of losing equal numbers of each type of population (uws, civs, mil),
you first lose uw's, then civs, then mil. As before, no more than 1/2 the total
population of a sector can starve in one update. Example: if you have 200 uw's,
100 mil, and 500 civilians, and no food, normally you'd have 100 uw's, 50 mil,
and 250 civs after the update. With NEW_STARVE in effect, you'd have 0 uw's,
300 civilians, and 100 mil. 
.s1
NEW_WORK: When moving civs to or from a sector with low work, the new loyalty
and work percentage of the destination sector is computed proportionally.
For example, of you move 100 people from a 0% work sector to a 100% work
destination sector with 100 people in it, the destination sector will have 200
50% work people in it. If you then moved in 100 people with a 100% work
percentage, the sector would have 300 67% work people in it.
.s1
CARRIER_WORK: carriers will now work on damaged planes on board. It's not much,
but it's something.
.s1
STOP: there are now 2 new commands, stop & start. If you stop a sector, it
will not gain efficiency or produce for 1 update. Start counteracts stop.
Census is also changed to report the production status of a sector.
.s1
CHANGES.CHAINSAW.3.3
.s1
Changes to the Chainsaw code in version 3.3
.s1
Sectors taken over have the their production stopped.
This should prevent the "redesignate a dozen tech centers" update attack.
If STOP is not defined, the new sector designation is set to be the
same as the current sector designation.

.s1
The 'file' utility now creates an all-sea world instead of not creating a world.

Ships
.in 0.6in
.L -
Ships now have three letter abbreviations.
.L -
"load" syntax has been changed to make it the same as the "move"
syntax.
.nf
- The following changes were made to the sonar command:
  - will only work from ships at sea
  - will only detect ships at sea
  - will now detect the shoreline
  - will only detect things if there is a straight line of water
    between the detector and the detected
  - now displays a map and changes your bmap
  - for ships with tech > 310, shows mines on the map with an X and
    puts the X on your bmap
.fi
.L -
All ships (including subs) in harbors are now visible via the \Q*lookout\U*
command by all ships (including subs) in adjacent sectors
.L -
If a NEUTRAL (or worse) ship sails within your coastwatch range,
then you will receive a telegram like this:
.nf
TheBorg lc2 light cruiser 2 (#666) sighted at -9,-1
.fi
This telegram is sent before any interdiction is done.  If you
want to turn this feature off, then type "toggle coastwatch off".
Note that you can also now turn off those nuisance sonar ping
detection telegrams by typing "toggle sonar off".
.L -
You may now tend land units which have
"assault" capability (see info tend).
.L -
"build" syntax has been simplified.  You no longer need to specify tech
level to build at (the default is your current tech level).  Also, the
 arg now comes before the  arg:

.EX build s 4,0 fb1
builds a fishing boat at current tech level.

.EX build s 4,0 fb1 5
builds 5 fishing boats at current tech level.

.EX build s 4,0 fb1 2 99
builds 2 fishing boats at tech level 99.

"show" output now shows you the total amount of avail used to build something.
.L -
The Autonav code has been completely rewritten and is dramatically
improved.  Thanks Chad!
.L -
You now get a telegram if someone loads something onto your ship or if
someone unloads into your harbour.
.L -
Load/Unload now tell you exactly how much stuff got loaded/unloaded
from each ship.
.L -
You can now only unload into a sector if you are friendly towards them.
.L -
The "coastwatch" command now shows ship names!  (Empire invents the
telescope!)
.L -
The "payoff" command now shows the distance your ship has
traveled--handy for making sure you pass those critical distances.
.L -
The tech level required to build aegis cruisers has been increased
from 150 to 260.
.L -
The following ships: "mc  missile cruiser", "aac aa cruiser", "agc
aegis cruiser", and "ncr nuc cruiser" have been given a new ship
capability called "anti-missile"  This means that they will use their
anti-missile systems to attempt to
intercept enemy missiles aimed at any ship within a 1 sector radius.
Note that just like abm & a-sat missile interception, only missiles
belonging to countries you are "Hostile" or "At War" with will be intercepted.
Thanks Chad!
.L -
Ship damage now always factors the armor value of the ship, no matter
where the damage comes from.  Also, whenever a ship is hit, the player
is told exactly how hard that particular ship was hit.
.L -
The "scuttle", "scrap", "mission", and "fuel" commands will now accept
"l" for the unit type.  (You are no longer required to type "la".)
.L -
Now when you load land units onto a ship, the code will automatically
try to supply them, and if they are out of supply, you will get a warning.

Subs
.in 0.6in
.L -
ASW planes will now fly out to track any non-FRIENDLY (including
NEUTRAL) sub movement.
.L -
However there is a chance that the plane won't even leave the ground
and notice any sub movement at all.  The chance of detection is
identchance = (1 - (1 - hitchance)^2).
.L -
ASW planes will no longer detect subs they fly over while flying an
interdiction mission.
.L -
Once the planes have arrived at the sector where the sub movement
was detected, then identchance is checked again.  If success, then
the plane is able to identify the owner of the sub.  If the owner
is neutral, then the player gets the message:
.nf
      np1 naval plane 1 #2 tracks TheBorg subs at 2,-6
.fi
If the plane is unable to identify the owner of the sub, then the
player gets the message:
.nf
      np1 naval plane 1 #2 detects sub movement in -3,-3
.fi
If the ship was identified as HOSTILE or AT_WAR, then the plane will
drop depth charges.
.L -
If depth-charges miss, then the ship owner will get
the message:
.nf
RUMBLE... your sub in 24,0 hears a depth-charge explode nearby
.fi
.L -
torp and fire will now only tell the victim that a "sub" torped
them, or that return fire damaged a "sub" (rather than giving out
detailed information about the sub number, type, and owner...)
.L -
max sonar range has been reduced to 7 and sonar output no longer
prints blank lines.
.L -
sonar has been changed in the following way:
detection = (source "spy" value) + (target "vis" value)
If the detection value is less than 8, then sonar will just print
.nf
  Sonar detects sub #12
.fi
If the detection value is above 7, then sonar will report the type of sub.
Only if the detection value is above 9 will the owner of
the sub be revealed.
.L -
For ASW planes flying "sonar" or "recon" missions, a similar change
has been made.  The plane needs to pass one identchance check to see
the type of sub, and needs to pass two identchance checks to see the
owner of the sub.
.L -
Note in both of the above cases, owner and type of FRIENDLY and
ALLIED subs will always be revealed.

Navigation
.in 0.6in
.L -
When you "nav" or "order" your ships, they will automatically avoid "x" and "X"
sectors on your bmap.
.L -
now when you navi (or march), any new sector designations
automatically appear on your nav map and get added to your bmap (you
no longer need to do a "look" to find out their designation.  Note
that subs will only see sea, harbors, and bridges and will have to
look" (and risk detection) to see anything else.
.L -
If you hit the wrong character, navi will now display all possible navi
commands.
.L -
You can now draw a 'M' map or a 'B' bmap while navigating.
.L -
You can list the ship you are navigating using 'i' and you can change
your flagship using 'f'.
.L -
Navigating using "nav", "order" or "sail" now calls exactly the same
code and will thus result in exactly the same risks (mines & interdiction).
.L -
Now you can type commands like this:
.EX nav 72 jlsruMluBursh
That is, you can mix directions with other navigation commands.
.L -
Interdiction of navigating ships now works as follows:
.NF
1. Forts interdict.
2. If there are any ships left, ships, land, planes interdict.
3. If there are any ships left, marine missiles on interdiction  fire one at a
   time until there are no ships left.
.FI
.L -
There is now a new kind of diplomatic relation that you can have with
a country: "Friendly" which falls between "Neutral" and "Allied".
This basically splits "Allied" into two steps: anything to do with
ships is available to "Friendly" nations (nav, load, unload, tend,
upgrade, order, sail, follow), whereas anything to do with planes or
military support is reserved for Allies.  This allows you to
establish trading relationships without the necessity of a military
relationship.  See info relation for full details.
.L -
If the BIG_CITY option is enabled, then small ships may navigate,
load, and unload in 2% cities.

Planes
.in 0.6in
.L -
Planes which are less than 40% efficient can not fly.
.L -
If you're tech is higher than 290, then you may not build planes with
tech lower than 150.
.L -
Planes will only abort if they have been damaged below 80% (it used to
be that they could abort at anything below 100%).
.L -
The range of marine missiles and SAM's has been reduced.
.L -
Air combat reports are now succinct tables with headers.  Much easier
to read.  Thanks Waffen!
.L -
New command "skywatch" scans your skies overhead for satellites.
Works very much like "coastwatch".
.L -
You can now filter your satellite output to list, for example, only
banks owned by country #7 which are over 60% efficient.  The selectors
available are exactly the same as those used by the "census", "ship",
and "land" commands.  See "info satellite" for more details.
.L -
A 75% satellite now only sees 75% of sectors (the rest are blank).
It's always the same 25% that are blank.
.L -
All missiles are now VTOL.  In particular, this means that missiles on
missions will now fire from anywhere (including on subs).
.L -
Surface missiles can now be put on interdiction mission.  To
distinguish surface missiles from anti-ship missiles, the latter have
been given a new capability called "marine".  Surface missiles on
interdiction will keep firing on the enemy until at least 100 damage
has been done.
.L -
Interdicting marine missiles will also fire on ships when they "fire".
.L -
Missiles and planes flying interdiction missions will now detonate
any nuclear warheads that they are carrying.
.L -
When you "arm" a missile or plane, you will be asked whether you
would like to program the warhead to airburst or groundburst.
.L -
Missiles and planes are now limited to a maximum of one warhead
apiece.
.L -
A-sats will now automatically attempt to intercept any satellites
launched by a country you're "Hostile" or "At War" with.  This works exactly the same
way as ABM defense.  Also, if you launch a satellite over a sector
which is owned by a non-ally then they will get a message telling them
that you have positioned a satellite over their sector.  In the age of
advanced telecommunication such things don't go unnoticed.
.L -
There is now only one formula for determining whether a plane/missile
hits its target and how much damage it does (including abm's and
a-sat's).  See "info bomb" for the formula.  In particular,
planes/missiles flying missions will now have exactly the same
hitchance as those flown by hand.

Land Units
.in 0.6in
.L -
Land units now have three letter abbreviations.
.L -
Artillery must be at least 20% efficient before it can fire.
.L -
The "lmine" command now allows you to lay as many land mines as you
want.  If the unit can't carry as many mines as you asked it to lay,
then it will just keep resupplying itself until it finishes the job.
Also, it now costs engineers 1 point of mobility per mine laid.
.L -
If land units are accompanied by engineers, then their chance of
hitting a land mine is reduced by a factor of 3.  E.g. if there 
are 25 mines in the sector, then a land unit has a 33%
chance of hitting a land mine.  If it is accompanied by an 
engineer, then that chance drops to 11%.
.L -
If an engineer sweeps a land mine that it cannot carry, it drops
it as a shell into the sector.
.L -
Engineers now sweep a number of times equal to 2 times the number
of shells they can carry.
.L -
The chance of an engineer finding a land mine in a sector is now
50% time the "att" value of the unit:
.nf
          # of sweeps   chance of finding a mine
old system   5            66%

.L -
You can now draw a 'M' map or a 'B' bmap while marching.  Also, if
you hit the wrong character, navi will now display all possible march
commands.
.L -
Fortifying a land unit no longer clears the unit's mission.
.L -
You can list the units you are marching using 'i' and you can change
your leader using 'f'.
.L -
Now you can type commands like this:
.EX mar 72 jlruMluBurh
That is, you can mix directions with other march commands.

Forts now do not cost anything to designate.
.L -
You may not fire a fort which is less than 5% efficient.
.L -
Forts will now only automatically interdict ships that the country
would be able to see using the "coastwatch" command.  Ships out of
visual range will not be interdicted by forts.  Note that
ship/ship, unit/ship, plane/ship interdiction was not changed,
and also the "fire" command was not changed.  _only_ fort/ship
interdiction was changed.

.L -
Harbors now have the same packing bonus as a warehouse.
.L -
You can now build bridges all on one line as in:
.EX build b 2,2 j
.L -
You are now only allowed to cede to nations which are Friendly towards you.
.L -
The new Empire command "strength" will show you the defense strength
of all your sectors (including number of land mines and reacting units
from nearby sectors).
.L -
The "test" command no longer requires there to be the commodity in
the sector (useful if you want to use that sector as a temporary
stopover and you don't want the stuff to get stranded there).
.L -
Shelling now factors in the efficiency of the sector into its
defensive bonus, so now a 0% bank defends the same as a 0% fort which
defends the same as a 0% road.  The formula for calculating the new
defense value of a sector is:
((defense - 2)*eff/100) + 2
.L -
The "neweff" command now checks to see if a sector has been stopped.
.L -
xdist and ydist are now in player coordinates.

Any interdiction of things being moved will also damage the sector
being moved into.  Note: this will slow down bridge attacks!

Combat
.in 0.6in
.L -
Defense against attack, assault, and paradrop is now exactly the same.
.L -
If attack odds are > 90%, then defensive support is no longer called.
This will put a stop to most shell-draining techniques.
.L -
You can now specify how many troops you want to board with.  Also, the
code now always forces you to leave at least 1 mil on your ship when
boarding.  You can also board from any sector type and with land units
having "assault" capability.  You may not board with more mil or units
than the boarded ship can hold.
.L -
You may not attack with supply, security, artillery, or
anti-aircraft (flak capability) land units.
.L -
Attacking land units & mil used to be taken out of the sectors/ship
they were attacking/assaulting/boarding from.  This caused endless problems
(including stranded units).  In the new code, mil and units stay where
they were until they have finished attacking.  The battle is assumed
to take place along the "border" between the two sectors.  Thus, the
attacking mil & land units will be vulnerable to shelling and
attacking while you are answering the attack prompts.
.L -
If, while you are answering the attack prompts, anything happens to
either the sector you are attacking, or the mil & units you are attacking
with, then you will be notified ("land unit #3 damaged from 80% to 50%",
"Your mil in 3,1 damaged from 180 to 12", "defending mil has been increased
from 10 to 250").
You will also be notified in this way if a bridge collapses, one of your
attacking sectors was taken, you were shelled, your enemy abandoned
the sector you were attacking, your land units reacted to fight another battle,
...)  You will be notified if any of these things change before the
battle and given a chance to abort your attack.  If for some reason it
is no longer possible to attack (e.g. you now own the sector, or a
bridge collapses) then the attack will be automatically aborted.
.L -
The sub-prompt for both the "attack with" and the "move in" questions
has changed to [ynYNq?].  The meanings of these 6 answers are:
.NF
y - yes this unit
n - no this unit
Y - yes all units in this army
N - no all units in this army
q - quit attack
? - print this help message
.FI
.L -
The server will now add up the mil you saw and the enemy land units your
scouts saw, and based on this info, it will estimate a defense strength of the
enemy.  If your scouts didn't see the efficiency of the enemy units, then
it will assume that they were at 100%.  Based on this estimated defense
strength, the server will calculate an estimate of your success odds for
you and if these
estimated odds are less than 50%, then the server will ask you if you're
sure you want to continue with the attack.  These estimates are
made before support is calculated, and before the enemy reacting
units have reacted, so it will not be particularly accurate.  However, if
by the time you've finished answering all the attack prompts something has
happened which has made your odds much worse than you expected (e.g. your
cavalry got shelled or your enemy beefed up his mil), then this will give
you a chance to abort the attack.
.L -
Immediately after a battle is won (i.e. before any move-in sub-prompts
are asked), 1 mil (first choice) or 1 land unit (second choice) is
automatically moved into the taken sector.  Not only does this put a
definitive stop to shell-draining tricks, but it also resolves what was a
big problem in the old code of the taken sector being owned but not
occuppied for a period.  This problem resulted in, among other things,
stranded land units.  It is impossible to strand a land unit in the new
code.
.L -
I have added a new option to the server called INTERDICT_ATT,
which, when enabled, calls the usual interdiction routines against
mil & land units moving into the victim sector after an attack.
The same chances of interdiction apply as in "move" and
"march".  The mil get interdicted sector by sector, and the
land units all at once.
.L -
In the new attack code, it is much harder for a unit to fail a morale check.
The new chance (recalculated after each hit) is (retreat% - unit efficiency).
Thus, a land unit which has a retreat percentage of 60% and is now 50%
efficient, will have a 10% chance of retreating with each hit.

The delivery and distribution stuff was removed from the output of
"commodity" and each column was widened to 5 characters (to accomodate
the new system where sectors are now allowed to hold up to 9999 of

Mountains will now mine gold at 3/4 the rate that gold mines do (thar's
gold 'n them thar hills!)
.L -
Mountains can now only hold 1/10th the population of normal sectors.

The mobility cost to move into a sector has been changed from:
.nf
    cost = (mcost - eff) / 5
  to:
    if (mcost < 25)
      cost = (2 + (3 - mcost) * eff) / 5
    else
      cost = (mcost - 20 * eff) / 5

OLD SYSTEM: eff   0%  100%     NEW SYSTEM: eff   0%  100%
              +  0.2   0.0                   +  0.4   0.0

.fi
Note that this means land units can attack 100% mountains now, so
there will be a tradeoff for the defender--either they can have a low
efficiency mountain that costs more mobility to attack but gets a
lower defense bonus, or they can have a high efficiency mountain that
costs less mobility to attack but gets a higher defense bonus.
.L -
New conditional query "coastal" which gets set when you take a

Planes
.in 0.6in

In the old system, planes would be charged either 10 mobility

flight.  This cost was then multiplied by (100 / eff) with the
restriction that plane mobility could not go below -32.  Planes flying
missions were charged only 1/4 of this.  In the new system, planes are
charged a base rate of 5 mobility to prepare for takeoff.  On top of
this, they are charged a flight cost which is either 10 (interceptors
and escorts) or 20 (the rest), however this flight cost is scaled down
according to the length of the flight--it is multiplied by (flight
length) / (max plane range).  The flight cost is then scaled by
(100/eff) with the restriction that a plane can't go below -32
mobility.  Planes flying missions are charged 1/2 of this.
.L -
The mobility of a plane will now go down by one point for every two
points of damage it took from air-to-air combat, to a limit of -32
mob.  This is to simulate the high mobility cost of air-to-air combat,
and the fact that air-to-air combat is more effort for low tech planes.
.L -
SAM interception is now separate from plane interception; for each
attacking plane, if it cost at least $1000 to build, then one SAM will
be launched at it.  After SAMs have been fired, fighter planes will
intercept what's left over.
.L -
The restriction that high tech nations can not build low tech planes
has been removed (the above changes address the f1 SAM-soaking problem).
.L -
Marine missiles on interdiction now fire at a single ship rather
than the whole fleet.  They pick the ship which is the most valuable
according to (cost to build) * efficiency.  Furthermore, marine
missiles will only launch at a ship if the ship cost >= $1000 to build
or if it can carry land units or planes.
.L -
Sectors which your planes fly over when they fly missions will now be
added to your bmap.

There are three new land units: 'cavalry 2', 'light infantry', and 'aau1'.  Here's the basic scheme.  The old cavalry are an average
between the somewhat weaker cav1 and somewhat stronger cav2.
light infantry are half the size of and slightly fastar than inf1's. 'aau1' come at the same tech as Zepplins and let low tech countries
try to throw rocks at low tech planes...

You now have 50 realms.

Each country now has two bmaps, their 'working' bmap and their 'true' bmap.  The true bmap contains only information put there by the
server.  The working bmap also contains information put there by the
bdes and sharebmap commands.  The 'bmap' command usually displays the
working bmap unless the player specifies 'bmap  true'.  
If the players working bmap becomes corrupted somehow, then they can
type 'bmap  revert' to revert their working bmap back to their
true bmap.  This change was necessary to prevent abuse of the new 'sharebmap' command (which compares the players true bmaps when
determining whether they overlap).
.L -
There is a new command "sharebmap  ".  If 
is friendly towards you and your 'true' bmaps already share enough information
in common, then your bmap will be added to their bmap.  For more details

If someone else was the last person to use your country, then when you

If the game is a blitz, then the 'players' command will list other
countries which are logged on.  This will cut down on the 'is anybody
else logged on?' announcements.  Note that for players, 'last command'
and 'user@hostname' are not printed (only deities get to see this stuff).

You can now read old announcements which you've already thrown away by
typing:
.SY "wire "
This works much in the same way as news.  The server automatically
deletes all announcements older than 7 days.

Changes to Empire 4.2.8 - Mon Oct  9 17:35:35 MDT 2000
 * Fixed range in radar.t and Sector-types.t.  Maximum range at infinite
   tech is 16.
 * Changed so that player can't drop civilians into occupied sectors.

Changes to Empire 4.2.7 - Fri Mar 10 18:41:04 PST 2000
 * Added new NF_SACKED flag to indicate when a country has had it's
   capital sacked.  This flag is only cleared when the country actively
   redesignates it's capital using the "capital" command, and changed
   capital.t to reflect this (no more re-sacking after an update if the
   country doesn't reset and repeating until they are out of cash.)
 * Added land unit to edit command for planes.
 * Added nuketype to edit command for planes.
 * Changed so that if the leader of a group of units is a train, the
   railways are used for bestpath instead of roadways.
 * Changed mission command to also print reaction radius of reserve
   missions when set for land units.
 * Changed Flak.t to reflect guns having to be loaded onto a land unit
   for flak to fire.
 * Changed so that visitor countries cannot change their name or password.
 * Changed so that you cannot upgrade deity planes, ships or units.
 * Changed so that you know where missions are flown from.
 * Changed so that the airport owner you fly a mission from is informed.
 * Changed so that preperations for takeoff are reported to the owner of
   the sector, ship or unit a plane is taking off from if it is not owned
   by the owner of the plane.
 * Changed so that when a sector reverts during a guerrilla revolt, the
   mobility is not reset.  When MOB_ACCESS is not enabled, this used to mean
   you would always get at least an updates worth of mobility.  With
   MOB_ACCESS, sectors that reverted during the update were useless, since you
   got no mobility for a long time.  This fixes that problem, and makes che
   more useful as well.
 * Changed so that air defense missions don't always send up every plane in the
   area, but instead always send up at most two times the number of incoming
   planes (for each interdicting country.) This helps to stop 1 plane from
   stripping the mobility from 25 air defense planes all at once, but doesn't
   limit it to n+1 as there is for regular interception.
 * Clarified deity reversion of sectors in Sector-ownership.t
 * Clarified production efficiency and added pointer to "show sector cap"
   in Product.t
 * Clarified nuketype selector for planes in Selector.t
 * Clarified that fortifying units does not affect mission status in info
   pages for mission and fortify.
 * Clarified fuel syntax upon error in fuel command in empmod.c.
 * Cleaned up comments causing minor complaints in some builds.
 * Fixed bug in loans where you could collect on proposed loans.
 * Fixed production command to be more accurate (though it *still* has some
   rounding errors, it's better.)
 * Fixed potential memory leak in air defense missions.
 * Fixed bug where you couldn't pinbomb some commodities if other commodities
   didn't already exist in the sector.
 * Fixed bug where you couldn't build 0 crew planes without military in the
   sector.  (This is different from needing at least 1 military to build all
   planes that need a crew which introduced another related bug earlier.)
 * Fixed bug where scrapping land unit 0 could cause erroneous transfer
   messages to be displayed for deity owned planes.
 * Fixed bug where land units on ships in a sector taken over were blown
   up or captured.
 * Fixed bug where planes on ships in a sector taken over were blown up
   or captured.
 * Fixed bug in sdump printing origx and origy in deity coordinates.
 * Fixed bug in satellites showing wrong sectors (sometimes) when using the
   optional arguments.
 * Fixed bug in launch showing wrong satellite target (showed asat instead
   of the target satellite.)
 * Fixed bug where you could gain information not normally available using
   the "fire" command to determine sector type information.
 * Fixed bug in market/trade creating extra money when loans are taken out.
 * Fixed problem with land units not being reported sunk after being sunk
   on a ship that was nuked or wastelanded in a sector.
 * Fixed problem with Spies.t using "llook" instead of "llookout".
 * Fixed problem in lwp/arch.c including jmp_buf.h instead of setjmp.h
   on some Linux boxes.
 * Fixed problem with plague infection being way too high in cities when
   the BIG_CITY option is enabled.
 * Fixed bug in edit command getting confused with arguments.
 * Fixed bug in ask_move_in_off asking you to move in a negative number of
   troops (hey, it could happen. :) )
 * Fixed bug in add command not keeping flags or relations initially correct.
 * Fixed bug in torpedo command sometimes telling victim about torpedo
   sightings even when way out of range.
 * Fixed bug in spy command not reporting planes in adjacent sectors, as well
   as not formatting them properly when reporting them.
 * Fixed bug in satellite with noisy transmission causing a potential
   crash of the server with non-100% efficient satellites.
 * Fixed potential crashing of the server during satellite display when not
   calculating distances to ships and units correctly.
 * Fixed bug where planes in non-allied sectors, ships and units could be
   used on missions.
 * Fixed bug where planes on the trading block could be used on missions.
 * Fixed bug where planes and units that get traded don't have mobility set
   correctly when using MOB_ACCESS option.
 * Fixed bug which made security units virtually useless.
 * Fixed access times and mobility not being set right when building planes,
   ships, units, bridges and bridge towers when MOB_ACCESS is enabled.
 * Fixed minor formatting problem with launch of satellites.
 * Fixed minor formatting problem with planes with greater than 999 tech.
 * Fixed minor formatting problem with ships with greater than 999 tech.
 * Fixed problem with "llook" showing up in TOP info file.
 * Fixed problem with lwp Makefile choking on NT builds with clean target.
 * General cleanup of potentially ambiguous statements.

Changes to Empire 4.2.6 - Fri Jun  4 05:55:20 PDT 1999
 * Added "TECH_POP" as an option where technology costs more to make
   as your population grows past 50K civilians.  It is disabled by
   default.
 * Changed "produce" command to accurately print what the true p.e. is.
 * Changed "update" command to display if mobility updating is enabled for
   MOB_ACCESS option.
 * Fixed bug where toggling off the coastwatch flag also turned off
   forts firing on hostile ships coming into range.
 * Fixed bug where assaulting your own land would violate any treaties
   you have where assaults are a violation.
 * Fixed bug where all planes (even those without need for a crew, such
   as missiles) needed at least 1 military to build.
 * Fixed bug where when a ship sinks during the update due to lack of maint,
   land units and planes on it were left stranded.
 * Fixed bug where when a land unit dies during the update due to lack of
   maint, land units and planes on it were left stranded on it.
 * Fixed bug where nukes could be lost due to MOB_ACCESS updating mobility
   while arming.
 * Fixed bug in "show sector capabilities" not showing products correctly.
 * Fixed bug in "show tower build" printing "bridges" instead of "bridge
   towers".
 * Fixed bug in sectors that don't revolt not showing up as lost items.
 * Fixed bug where maps with an X of exactly 200 is not drawing third line.
 * Fixed bug where MOB_ACCESS was not updating the mobility just before
   the update. 
 * Fixed bug in the way treaties are examined and sometimes produce
   wrong results.
 * Fixed edit to allow creating negative mobility for sectors.
 * Fixed setsector to allow creating negative mobility for sectors.
 * Fixed bug where when writing out the value of a sector that had
   negative mobility and was damaged in combat, mobility was being
   set back to 0.
 * Fixed Taxes.t info page to reflect that captured civvies only pay
   1/4 taxes.
 * Fixed Technology.t info page to reflect TECH_POP option.
 * Fixed navigate.t info page to reflect that only ships in the fleet
   in the same sector that are fired upon have damage divided up.
 * Made techlists toggle on by default (so things are shown in order of
   technological advances.)

Changes to Empire 4.2.5 - Mon Mar  1 06:42:24 PST 1999
 * Added optimization to increasing mobility to check if an object is
   already at max mob, just return since it can't be increased.
 * Added "-ltermcap" for client libs for hp build (it was already in
   hpux build.)
 * Added clearing of telegram flags after the update so that the next
   telegram is flagged as new and not part of the update.
 * Fixed Update-sequence.t to reflect MOB_ACCESS.
 * Fixed bug where fortification amount was not being limited to
   maximum mobility for land units (land_mob_max).
 * Fixed bug where land unit fortification strength was being calculated
   by using 127 instead of land_mob_max.
 * Fixed bug where scrapping land units was creating military.
 * Fixed description of sect_mob_neg_factor in econfig file.
 * Increased speed of PT boats.
	
Changes to Empire 4.2.4 - Tue Feb  2 05:47:44 PST 1999
 * Added check to make military values match up correctly for land
   units.
 * Fixed bug in doconfig not putting ipglob.c in the right place.
 * Fixed bug where attacking deity sectors will violate a treaty.
 * Fixed newspaper.t information file.
 * Fixed potential bug in fixing up timestamp information when restarting a
   game with MOB_ACCESS turned on.
 * Fixed bug in explore command not setting mobility to correct
   value when MOB_ACCESS was enabled.
 * Fixed bug in enlist setting mobility incorrectly sometimes.
 * Added doc/backup file for deities which recommends how backups and 
   restores of the data directory should be done.

Changes to Empire 4.2.3 - Wed Jan 13 06:02:35 PST 1999
 * Added linux-pthreads target and build for using pthreads under Linux.
 * Added NO_FORT_FIRE option which disables the ability of forts to
   fire when enabled.
 * Added more error checking and recovery for corrupt data files.
 * Changed alphapos target to alpha-pthreads for better clarity.
 * Changed fairland to allow 0 sector distance to other islands and
   continents (James Risner)
 * Changed "frg" and "dam" land unit stats to "rng" and "fir" so they
   match the way ships are described (since this is how they really work.)
 * Changed Unit-types.t to now describe "rng" as firing range of a unit,
   and "fir" as the number of guns that a land unit fires.
 * Cleaned up misc. build warnings.
 * Changed artillery damage to be 5 + d6 per gun firing from just d6
   per gun firing and updated Damage.t to reflect this change.
 * Changed artillery firing ranges to be like ships ranges - divided
   by two, and modified them to make more sense.
 * Changed artillery units to be "slightly" :) more powerful.
 * Changed "cavalry" unit to tech 30 and lowered mil content to 20.
 * Changed "artillery" unit to tech 35.
 * Changed so that guns are no longer required to build units, and
   that guns must be loaded onto artillery units for them to fire.
   Client developers note: the show command has not changed yet to
   remove the 'guns' column (since guns are no longer required) but
   will in a future revision (possibly 4.2.4) so "be prepared" for
   "show land build" to change. :)
 * Fixed landunitgun to handle all the damage calculations like it should.
 * Fixed bug sinking planes when the ship they are on sinks.
 * Fixed bug destroying planes when the land unit they are on is destroyed.
 * Fixed bug where land units could fire support without enough military.
 * Fixed bug in abandoning sectors by marching out a land unit where it
   would not let you sometimes (uninitialized variable problem.)
 * Fixed gets problem in files.c (James Risner)
 * Fixed bug in determinig operations range of a ship.
 * Fixed bug in building planes where you could manufacture military.
 * Fixed warnings in threading package(s).
 * Fixed fire.t to reflect new firing changes.
 * Fixed lstat.t to reflect new firing changes.
 * Fixed sstat.t to reflect the way things really work.
 * Fixed Ship-types.t to reflect the way things really work.
 * Fixed the way shutdowns work to hopefully better protect data files.
 * Fixed bug in attacking when sector mobility is less than 0 and it would
   prompt for attacking with a negative amount of military.
 * Fixed typo in fire.t stating wrong parameters for firing from a sector.
 * Fixed bug in client when it prompts for country name it was putting
   an extraneous end of line on the end that needed to be stripped off.
 * Fixed problems running on Linux running on an Alpha machine.  Thanks
   to Rocky Mountain Internet and Jeremy A. Cunningham for giving us time
   on a machine to work out the bugs.  (Note that the only build that
   works on Linux/Alpha is the linux-pthreads)

Changes to Empire 4.2.2 - Sun Dec 27 12:46:34 PST 1998
 * Added some code optimizations into the update code when building paths.
 * Added some new cacheing for building paths to help speed up updates.
 * Added so that you can use "name" and "password" with the change command
   as well as "country" and "representative".
 * Added flag to power command so that if you are a deity and enter
   a negative number of countries you want to see, you see the power chart
   for that many countries without power numbers on the next line.  Only
   useful for deities that want to see the chart un-broken up by that line.
 * Added new functionality to fortify command.  You can now use a negative
   fortification value to cause the unit to be fortified and leave at
   least that much mobility on the unit. I.E. "fort * -67" will fortify
   all units and make sure the mobility of each unit doesn't go below
   67.  If the mobility is already below that level (or equal) the unit
   is left unchanged.
 * Added that the realm command prints "Realm #n is x:x,y:y" after
   you set a new realm.
 * Added TREATIES option and enabled it by default.
 * Added "no depth-charging subs" and "no new land units" treaty
   clauses.
 * Added Trannie Carter's basic client fix to use fgets instead of gets.
 * Changed market and command to only print the lowest priced lot of
    each given commodity by default.  If you specify "all" it shows
    all lots on the market, and if you specify a specific item, it shows
    all lots of that item type.
 * Changed start command to only write out sector if it changed.
 * Changed stop command to only write out sector if it changed.
 * Changed how plane names were changed on server startup if the
   PLANENAMES option was enabled.
 * Changed move command to use standard askyn function for abandoning
   sector prompt.
 * Changed plane overlight sightings to take stealth into account,
   and if the planes managed to evade all flak and interceptors, they
   are not marked as "spotted" over enemy sectors.
 * Changed all units with the supply flag to have their marching speeds
   based on efficiency since that is their purpose.  What this means is
   that supply units and trains are more effective at 100% than at 10%
   (just as fighting units are more effective at 100% than at 10%, but
    their effectiveness is determined by how well they fight, not how well
    they "run away, run away!" :) )
 * Changed so that flash toggle is on by default for POGO at setup
   time.
 * Changed so that when a sector is taken, all land units owned by the
   current owner are treated as planes are during takeovers (i.e. there
   is a pretty good chance they are blown up, and if not, they change owner
   to the attacker and are beat up pretty good.)
 * Fixed treaties to work again.
 * Fixed bug in taking over land units not using correct pointer (can
   cause a crash or data corruption.)
 * Fixed collect command to wipe deliver and distribution information
   correctly.
 * Fixed potential bug in bmap not working when destination bmap has
   blank spaces in it.
 * Fixed bug in shark command not getting right nation structure.
 * Fixed bug in server where empty commands (for example, all spaces
   or tabs) were being reported as bogus commands.  They are now just
   ignored.
 * Fixed bug in scrap not dropping land units off of scrapped units carrying
   them.
 * Fixed bug in news where boarding of land units was reported backwards.
 * Fixed bug in calculating new people when growing them during an update.
 * Fixed missing -ltermcap in HP/UX build.
 * Fixed setsector to limit mobility to 127 not 255 (255 was being caught
   later and being reset to 0 anyway)
 * Fixed Sector-types.t to show a '\' instead of a '/' for wasteland,
   since that is what it really is.
 * Fixed retreat.t documentation to reflect the "retreat upon failed
   boarding" flag.
 * Fixed bug where satellites were not orbiting the world during the
   update.
 * Fixed bug in torpedos being too smart.  They knew how to jump over
   land! :)  Now the "line_of_sight" routine is used to determine if a 
   torpedo has a straight path to the destination.  If it doesn't, the
   torpedo no longer jumps over land, but instead slams into it.  This was
   an interesting bug because you could torp ships on the other side of
   a very skinny island as long as they were in range, even if there was
   no sea route possible.
 * Fixed bug when pinbombing and you run out of an object to pinbomb (land
   units for example) but you still have to pick something to bomb.  For
   ships it worked ok (just aborted that it couldn't find any more ships)
   and this was fixed for land units and planes.
 * Fixed server crashing bug when flying a plane and not carrying
   any cargo.
 * Fixed bug in move losing commodities when it runs out of room in the
   destination sector.  Goods are now attempted to be returned to the
   start sector, and apporpriate steps taken if the start sector is no
   longer available.
 * Fixed march to prompt you before you abandon a sector you own by 
   marching out the last land unit.
 * Fixed check functions to only check the relevant portions of the structure 
   and not the timestamp info that doesn't affect how the object functions.
 * Fixed bug in spy command that always told you if a spy unit was in a
   non-owned sector.
 * Fixed bug in displaying of land unit missions not showing correct land
   unit range.
 * Fixed bug in wire command where new announcements that you read at
   the last second don't get wiped out properly.
 * Fixed bug where announcement file could be corrupted by very long lines.
 * Fixed bug where bmap was not set when player was told what kind of
   sector they were attacking (this was an old abusable bug that was
   removed long ago to fix the abuse, and it's been fixed in a non-abusable
   way finally.)
 * Fixed bug where change command would warn you about monetary and
   BTU costs, but not prompt you to break out if you didn't want to really
   change your country name.
 * Fixed bug in sub-launched nukes that are intercepted being reported in
   the news incorrectly.
 * Fixed bug in load where you could abandon a sector and not know it by
   loading your last civilians or military onto a ship.
 * Fixed potential memory leak in autonav code.
 * Fixed potential bug where you could possibly determine if a sector is
   owned or not using one way plane missions.
 * Fixed Damage.t info page to properly show damages for planes and
   land unit shelling.
 * Fixed deliver.t to include syntax for command.
 * Fixed country.t to include syntax for command.
 * Fixed bug where ships on orders were not adding radar information to
   the bmap during an update.
 * Fixed bug where ships on sail were not adding radar information to
   the bmap during an update.
 * Fixed bestownedpath code to use the bmap properly.  Note this is a very
   important bug fix.  When navigating a ship, players are no longer given
   free information that they would not normally know.  For example, if you
   try sailing your ship off into uncharted areas of your bmap, the bestpath
   code will only use as much information as you have on-hand (i.e. your
   bmap) to plan out your path for you.  If you have no information on an
   area, it just keeps forging on, until bumping into something.  Of course,
   after the initial exploration through an area, the bmap will be set and
   used for all future sailings through that area.  Harbors and bridges
   are still checked for construction worthiness if you know where they
   are (i.e. they are on your bmap.) (Overall, what happened before
   was that the bestpath code would route your ship around islands that
   you didn't even know were there, and you could use various commands
   to see how that ship was going to sail during the update and thus you
   gained information that you wouldn't normally know.)
 * Merged bestpath and bestownedpath and wrote new wrappers, "BestShipPath"
   and "BestAirPath" to use it properly.  It is also good to note that
   bestownedpath is used to determine paths for ships and for planes, 
   and that best_path (which uses the A* algorithm) is used for all land
   based paths, and that the two are never interchanged.
 * Removed "jet recon" plane (it slipped in during the PLANENAMES conversion,
   and RECON was never used before.)
 * Removed extraneous "resnoise" and "resbenefit" functions and combined
   the two for setresource and setsector commands.

Changes to Empire 4.2.1 - Tue Nov  3 12:56:20 PST 1998
 * Fixed problem with global/plane.c not defining last structure element
   properly, and thus causing crashes when accessing certain plane
   routines.  This happened during the move to make the PLANENAMES option
   run-time configurable.
	
Changes to Empire 4.2.0 - Thu Oct 29 06:27:15 PST 1998
 * Bumped rev to 4.2.0 since this is a major release (the server is now
   run-time configurable for just about everything and is released under
   the GNU GPL.)
 * Put in official licensing information.
 * Re-arranged and commented the econfig (Empire Configuration) file.  The
   auto-generated "data/econfig" file is now pumped out chock full of
   comments (which may or may not be useful.)  Since the server is
   pretty much fully run-time configurable (MAXNOC is not, but it gets
   a default of 99 anyway) deities will probably be spending more time
   in the config file.
 * Added server support for building under NT, including mods from
   Doug Hay and Steve McClure to get the server building and running
   under NT. (This was built using MSVC++ 5.0 on NT 4.0 and command
   line "nmake nt")
 * Added Doug Hay's ntthread.c implementation for NT threading.
 * Added max pop column to "show sector stats" output.
 * Added lboard command for boarding land units from sectors.  Only raw
   mil can board land units, and only mil and land units aboard the unit
   being boarded fight back.
 * Added GODNEWS option.  When enabled, the deity giving people stuff
   is shown in the news.
 * Added bridge tower sector ('@')
 * Added BRIDGETOWERS option.  When enabled you can build bridge towers
   from a bridge span.  You can then build bridge spans from the tower.
   If the tower is destroyed ( <20% eff) bridges connected fall unless
   supported on the other side.  You can only build bridge towers in open
   water not adjacent to land and other towers.  Expensive.
 * Added plains sector ('~') - Max pop is 1/40th regular sectors, and
   it is deity creatable only (can't redesignate unless you wasteland it
   with a nuke :) )
 * Changed "info all" to no longer use printdir, instead it just uses the "all"
   info page which contains this information.
 * Changed so you can now load up to 2 spy units onto non-land unit carrying
   submarines if the LANDSPIES option is enabled.  Useful for sneaking up
   to shore and spying on your neighbors.
 * Changed so spies unloaded from ships are not given as gifts, they are just
   unloaded quietly.
 * Changed build command to handle building towers ("build t")
 * Changed show command to show tower stats ("show t b")
 * Changed reject so you can now reject things from any country except
   deity countries (this now includes sanctuary countries and visitor
   countries you don't want to deal with)
 * Changed ndump to dump nuclear stockpile ID as well.
 * Changed flash so that if someone allied to you is either not logged on or
   not accepting flashes, you are notified.  This is info you could gain
   otherwise since you can see other countries that are allied to you via
   players.
 * Fixed bug in news command when HIDDEN mods are enabled.
 * Fixed distribute command to only write out to the database if we
   actually changed the sector (i.e. if we really moved the dist
   center, we write.  Otherwise, it makes no point.)
 * Fixed threshold command to only write out to the database if
   we actually changed the sector (i.e. if we really changed the
   threshold, we write.  Otherwise, it makes no point.)
 * Fixed - population growth and truncation in "Update-sequence.t" info
   file is now clearer
 * Fixed the way fortify takes mobility away from a land unit if
   engineers are present.
 * Fixed bug in buying commodities at the last minute not resetting the
   time correctly in all situations.
 * Fixed bug in building nukes where it would always ask if you tried
   building more than one at a time.
 * Fixed bug where if you put (either by building or by transporting)
   more than 127 of one type of nuke in a sector, they all got lost. A
   negative wrapover sort of thing.
 * Fixed ndump to print # of stockpiles dumped.
 * Fixed ndump.t to reflect changes
 * Fixed bug in build command that didn't account for EOL characters.
 * Fixed bug where you could use planes to drop conquered populace
 * Fixed bug in distribute command in how it checked for current distribution
   sector.
 * Fixed pr_flash and pr_inform to no longer send messages if the player
   is still in the process of logging in (i.e. not in the PLAYING state)
 * Fixed report command output for deities.
 * Fixed bug in nuclear damage either taking out submarines when it
   shouldn't, or not taking them out when it should.
 * Fixed bug in loading units that are carrying units onto other units
   (note that it doesn't happen since only HEAVY units can carry other
   units and that check works, but that might change some day, and we
   don't want units carrying units to be carried by other units, etc. :) )
 * Fixed info pages to reflect new sector types.
 * Fixed info pages to reflect new spy unit capabilities.
 * Fixed show commands to only show trade ships if the TRADESHIPS option
   is enabled.
 * Fixed build command to only allow building of trade ships if the
   TRADESHIPS options is enabled.
 * Fixed up some definitions located in many places used for checking
   sectors for navigation rights.
 * Fixed power.t to correctly describe NEW_POWER formula.
 * Made HIDDEN option run time configurable.
 * Made LOSE_CONTACT option run time configurable.
 * Made ORBIT option run time configurable.
 * Made SAIL option run time configurable.
 * Made MOB_ACCESS option run time configurable.
 * Made FALLOUT option run time configurable.
 * Made SLOW_WAR option run time configurable.
 * Made SNEAK_ATTACK option run time configurable.
 * Made WORLD_X and WORLD_Y run time configurable.
 * Made MARKET option run time configurable.
 * Made LOANS option run time configurable.
 * Made BIG_CITY option run time configurable.
 * Made TRADESHIPS option run time configurable.
 * Made SHIPNAMES option run time configurable.
 * Made DEMANDUPDATE option run time configurable.
 * Made UPDATESCHED option run time configurable.
 * Made LANDSPIES option run time configurable.
 * Made NONUKES option run time configurable.
 * Made PLANENAMES option run time configurable.
 * Removed SMALL_SERVER stuff (unused baggage)
 * Removed trading post sector ('v')

Changes to Empire 4.0.18 - Thu Sep 24 06:54:27 PDT 1998
 * Fixed bug in aircombat where planes in flight could intercept air
   defense planes and take no damage (i.e. they got to fight twice,
   once for free.)
 * Fixed bug in freeing memory after performing missions that could crash
   the server (it mainly happened after an interdiction mission using
   planes and escorts, where some escorts came from airports that didn't have
   bombers going up.  Freeing the leftover escorts was crashing the server.)
 * Fixed bug where you could load non-existant units if you were allied
   with country #0.
 * Fixed bug where you could pin-bomb a plane with itself.

   to due to a perceived change in item status.
 * Fixed bug in mfir.c where a bogus input to a target could crash
   the server.
 * Fixed bug that after you read telegrams new telegrams may not send
   an inform message (the old telegram flags were not cleared.)
 * Fixed bug where fort support distance calculations are calculated
   twice instead of just once.  This bug caused a lower percentage
   of support fire than designed.
 * Fixed bomb.t to reflect land unit changes.
 * Put in some integrity checking for planes returing from bombing runs.
 * Added ability to edit land unit that a land unit is loaded on in
   edit command.
 * Consolidated bridgefall code into "knockdown" function (this code
   existed in at least 3 places, and was different in all of them.)
 * Subs returning fire are no longer reported in the news.
 * Visitor countries can now use the 'motd' command.
 * When trying to use a visitor country, if it is in use, you are not told
   by whom, just that it is in use.

   shells if not needed (out of range)
 * Updated Education.t

 * Added ability for "spy" to report all units/planes not owned by you
   that exist in the sector you are spying from.
 * Modified naval planes and anti-sub planes.
 * Changed so that missiles and bombs that miss their targets cause
   collateral damage in the target sector (they have to land somewhere!)
 * Changed llook so that non-spy units are required to have at least 1
   military personnel on board to see anything.
 * Fixed "llookout.t" to reflect change for military requirement.
 * Updated Plague.t
 * Updated upgrade.t
 * Added "lmine" flag for deities to see what sectors have mines in them
   (works for sea and land mines, used "lmine" to distinguish it from "min"
   which determines mineral (iron) content of a sector.)
 * No longer able to pin bomb land units on a ship.
 * Land units are required to have at least one military loaded to perform 
   a mission.
 * Firing land units are required to have at least on military loaded to
   be able to fire (or return fire.)
 * Spies are not always seen when being pinbombed.  You have to look very
   carefully for them (as you usually would.)
 * Fixed typo in "Spies.t"
 * Added new info about spy ability to spy.t.
 * Updated tax information in Innards.t and Update-sequence.t
 * Fixed typo in fire.t information about units firing on ships.

   having the sweep ability, ships would get hit by mines for doing
   nothing.
 * Fixed bug in count_land_planes always writing out land units unnecessarily.
 * Fixed bug in count_planes always writing out ships unnecessarily.
 * Fixed bug in lnd_count_units always writing out land units unnecessarily.
 * Fixed bug in count_units always writing out ships unnecessarily.
 * Fixed bug in llook that reported units on ships.
 * Fixed bug in llook that reported satellites launched over the unit.
 * Fixed bug in llook that always reported spies (it should be a 10-100%
   chance)
 * Fixed bug in anti possibly not saving lost items correctly.
 * Fixed bug in planes getting extended range when on missions and the
   op center is not where the plane is located.
 * Fixed bug in land unit defensive strength not being based on the eff of
   the unit when calculating odds of a battle.
 * Fixed bug in board not reporting consistant information.
 * Fixed bug in the way land unit casualties were being taken.

   Larsen.  They are described with other changes below.
 * Fixed bugs in the following commands that allowed two cooperating
   countries to create infinite numbers of any commodity and/or cash
   at any time (race conditions in the server): build, board, deliver,
   designate, distribute, explore, fuel, improve, load, ltend, mobquota,
   move, name, order, reset, sail, sell, set, tend, territory, test,
   threshold, torpedo, transport, unload

   some reason, this was causing a problem on one of the Linux builds (??).
 * Added "show sector capabilities" functionality (this didn't exist
   before.)
 * Fixed bug in neweff not reporting stopped sectors.  It now (correctly)
   reports them as not changing eff.
	
Changes to Empire 4.0.15 - Wed May 20 12:35:53 EDT 1998
 * Fixed the spelling of Markus' name in CHANGES4.0 files.
 * Added Markus' patches/fixes.  Some are detailed below.

   mil on units and ships)
 * Fixed bug in printing of "No ship(s)" twice in cargo command when no
   ships were selected.

   that has a bridge collapse are being sunk.
 * Fixed bug in update/produce.c when a sector overflows it's capacity
   on production.
 * Fixed bug in produce command reporting incorrect costs (sometimes).
 * Land units on ships will now try to draw supply from the ship they
   are on.
	
Changes to Empire 4.0.13 - Mon Mar  2 11:04:28 EST 1998
 * Fixed bug in distribute when world sizes are other than 64x32
 * Fixed bug in getcommand (not really a bug, just made it work like
   it used to so that the players command is useful for deities
   again)
 * Fixed building of POSIX threads on Alpha running Digital Unix.
 * Fixed line_of_sight prototype in sona.c
 * Fixed fairland not to conuse stupid C++ compilers.
	
Changes to Empire 4.0.12 - Tue Feb 24 11:27:31 EST 1998
 * Fixed client build on linux (whoops)
	
Changes to Empire 4.0.11 - Tue Feb 10 10:53:10 EST 1998
 * AIX build seems to only work with gcc right now (but at least that works)
 * Vax Ultrix (vaxultrix) build should work now (hopefully) out of the box.
 * Took out autosupply of airports when bombing or dropping shells.
    (This was the only commodity this was done for, and it was creating
    problems since supply is still somewhat broken somewhere)
 * Included Curtis Larsen's, Markus Armbruster's and Sverker Wiberg's
    submitted patches, which collectively included cleaning up most
    of the server prototypes and bogus declarations.  Many thanks.
 * Increased incoming command buffer to 1024 from 512 bytes
 * Increased the # of parsed arguments from 64 to 100
 * Fixed bug where spies were not dying when damaged.
 * Fixed bug in HIDDEN mods in declare command not printing country # of
    uncontacted country correctly (or at all as a matter of fact)
	
Changes to Empire 4.0.10 - Mon Aug 18 12:34:58 EDT 1997
 * Fixed bug where fleets were being interdicted but the damage was being
    spread to ships not in the same sectors.
 * Fixed but in market when buying goods without enough cash.
 * Planes in orbit over airports are no longer fixed up during updates.
 * Planes in orbit are no longer damaged when the sectors they are over
    are damaged.
 * Planes on ships are no longer damaged when the sectors they are in are
    damaged, unless the ship is damaged.
 * Fixed problem with no newline after partisan activity telegram in
    anti.c
 * Fixed problem in chan.c printing out change costs incorrectly.
 * Fixed problem in dispatch.c screwing things up on redirection.
 * financial should now handle 6 and 7 digit loans.
 * Planes on ships that are in sectors that revolt are no longer taken
    over.
 * Fixed bug in powe.c where the power report was mis-calculating the
    efficiency of planes.
 * Fixed doconfig.c to use STDC instead of multi-level #ifdefs.
 * Fixed bug in parse.c that was screwing up double quotes in conditional
    arguments.
 * Military in a sector now only produce up to maxpop, just like civvies
    and uw's.  No more stuffing 6K mil into a mountain to max it out.  You
    can still hold more mil there over the updates, but the extras just
    won't produce anymore.
 * Fixed bug in shark that allowed you to shark up loans even if you couldn't
    cover the debt.
 * Fixed bug in day of week calculation for server up time in common/keyword.c
    that is used for gamedays.
 * Documented what happens to standing military in collect.t when you collect
    a sector.
 * Documented mountains only holding and using 1/10th of the normal sector
    population in Sector-types.t.
 * Fixed documentation on ship's firing ranges in fire.t to be less 
    ambiguous.
 * Updated nukes in nuke.t
 * Added apropos command (thanks to Mike Wise)
 * Added case-insensitivity to the info command (thanks to Mike Wise).  If
    there are two files of the same name, and you don't get a complete match,
    then whichever file is found first in the directory is used.
 * Changed documentation in wantupd.h
	
Changes to Empire 4.0.9 - Sat Apr 19 23:01:51 EDT 1997

 * Fixed bug in satellite output for <100% satellites.
 * Fixed bug in load/unload not putting a newline after some unloadings
    in allied sectors.
 * Fixed bug in harden not printing correct values.
 * Fixed bug in creating/moving/etc. nuclear stockpiles.
 * Fixed bug where subs were trying to torp commodities moving on land when
    on interdiction.  (This was funny ;-) )
 * Fixed bug in "move" where you could keep a sector even after someone else
    took it from you.
 * Budget now correctly reports the # of units being built.
 * Mil on units & ships are now reported as normal military costs, not
    ship or unit maintainence costs in budget.
 * Fixed bug in update code where taxes could potentially be initialized
    incorrectly (affected budgets too.)
 * Fixed bug in nat.h header so that it uses SCT_MAXDEF instead of a fixed
    number (that was incorrect.)
 * Fixed bug with trains - they needed the xlight flag to carry planes.
 * Revamped and improved flak.
 * Added "Flak" info page.
 * Added "Fallout" info page.
 * Fixed repay/offer/consider to all need a capital to be used.
 * Fixed bug with air defense missions not running when not AT WAR.  They now
    fly when HOSTILE.
 * plane/ship/unit short names are all now 4 characters, padded if needed.
 * pdump/sdump/ldump/ndump now just print the short name for the type.
 * sdump now has ship name at very end in quotes.
    These were done at the request of some client developers for ease of use.
 * Fixed extra space in the dump output.
 * Fixed fallout - not quite so nasty anymore.
 * Fixed fallout - things on ships/units are damaged now.
 * Fixed and balanced planes/ships/units/nukes in conjunction with each other.
 * Fixed bug in doconfig.c calculating wrong s_p_etu sometimes.
 * Fixed bug where harbors weren't being used to resupply.
 * Fixed bug where selling units loaded with planes and units wouldn't take
    the loaded planes or units - they are now dropped.
 * Fixed bug in arm/disarm where you could arm/disarm planes on the trading
    block.
 * Deities can now remove things from the trading block/market.
 * Fixed bug in "work" not charging engineers enough mob.
 * Fixed bug in "work" not adding teardown and buildup avail costs together.
 * Subs no longer need mobility to return fire when fired upon.
 * Fixed "reset".
 * Fixed bug in "trade" allowing 2 players to pay for the same item, but only
    the last player gets it.
 * Fixed bug where you couldn't launch missiles from allied ships or sectors.
 * Fixed bombing so that pin-bombing can cause collateral damage too.
 * Fixed sector damage to damage planes there too.
 * Fixed flag in lload so that it doesn't always print if not needed.
 * Fixed "sell.t" info page.
 * Fixed bug in "buy" where not entering the price correctly could cause
    a crash.
 * Fixed "sell" so that at least 1 mobility is required to sell goods.  Keeps
    the midnight "raid and sell" abuse down. :)
 * Fixed "show plane cap" to move the last column over 1 more where it should
    be.
 * Fixed timestamps to be updated for units/planes on ships/units that move,
    since those units/planes move too.

Changes to Empire 4.0.8 - Wed Feb 26 23:00:51 EST 1997
 * Fixed bug in nstr_exec that was wiping out the previous conditional.
    This was major because it affected timestamp values which are more
    than 65535.
 * Fixed bug in sdump.c for typo in reporting the trade ships origin.
	
Changes to Empire 4.0.7 - Mon Feb 24 22:48:54 EST 1997
 * Fixed bug in aircombat.c when calculating the air combat odds.  Negative
    numbers were screwing things up good...
 * Fort sector's coordinates are no longer printed when auto-firing at
    ships.
 * Subs can now surface and fire deck guns (again)  They can also be
    hit by return fire when doing so.
 * Fixed bug in setting of plane attack and defensive values so that
    negative numbers don't keep going further negative.
 * Fixed incorrect military control calculation in the sell command.
 * Trading posts are no longer required to sell goods from.  You can sell
    from harbors and warehouses now too.
 * Spy now prints out the owner of land units you see when spying.  Before
    this was assumed to be sector owner, which is no longer true.
 * Loading land units now prints out what was loaded onto each unit,
    just as loading ships do.
 * Added fallout, coast, c_del, m_del, c_cut and m_cut to dump output.
 * Added "GO_RENEW" option.  This option means that gold and oil resources
    are renewable.
 * Added "lost_items_timeout" config variable, and set the default to
    48 hours.  This determines how long lost items stay in the lost items
    database.
 * Fixed land unit names to be more consistent.
 * Fixed mission.t info page.
 * Fixed bug in that if mission_mob_cost was set to 0, even negative
    mob units should be able to be put on missions.
 * Removed restriction on things needing to be at least 60% to be put
    on a mission.  Note that while you can put them on missions at < 60%
    now, when trying to do the mission, it still checks the eff.  This
    is to help in automatic setup (build, put on mission, forget) instead
    of having to come back repeatedly.
 * Spies caught in Neutral or Friendly countries cause the Neutral or
    Friendly country to go Hostile towards the owner of the spy.
 * Tweaked ammunition numbers for artillery units.
 * No more automatic declarations of War should be made.  You will go 
    hostile, but since going to war doesn't increase your countries
    defenses, and is purely political, it is left to the player to go
    that final step.
 * Fixed bug in trade that wasn't incrementing the time if last second bidding.
 * Fixed bug in "lmine" that was crashing the server if the land unit was
    out of mobility.
 * Fixed buy so that if you specify a product, you can only bid on that
    type of product.
 * Added "lost.t" info page.
 * Added "lost items" database (EF_LOST)
 * Fixed bug where you could move in allied forces after an attack if they
    bordered the victim area.
 * Fixed nstr_comp to deal with values > 16 bits coming in from
    client for comparisons.
 * Changed last minute market/trade timers to increment 5 minutes.  2 minutes
    was too quick.
 * Fixed decode in lib/common/nstr_subs.c to deal with NSC_TIME better.
 * Commented out the logging of the market checking in server/marketup.c,
    lib/commands/buy.c and lib/commands/trad.c  It was generating lots of
    pretty much useless data that made parsing the server.log file more
    more difficult than it needed to be.
 * Fixed crashing bug in ldump.
 * sdump, ldump, ndump, pdump and dump now print out the current
    timestamp on the "DUMP XXX" line.
 * Fixed denial of service bug in lib/player/accept.c in
    player_find_other function.
 * Fixed bug in shark reporting incorrect buyer of the loan.
 * Fixed bug in sdump.c (case 0 should have been case 10)
 * ldump and sdump now always print the fuel column if asked for,
    even if opt_FUEL is turned off.  In the case that it is turned
    off, the fuel is listed as 0.
 * Added "timestamp" field, which is updated every time an item is
    changed.
 * Fixed up the Clients.t info page.
 * sdump now prints trade ship building origin.
 * sdump now always prints name even if SHIPNAMES isn't defined.  If
    it is not defined, then the name is empty.
 * Added "timestamp" to info/Concepts/Selector.t
 * Added some more relevant info to info/Server/Empire4.t
 * Fixed Infrastructure.t info page to reflect the fact that infrastructure
    is no longer torn down when a sector is re-designated.
 * Fixed sell.t to more accurately reflect the time-delay market.
 * Fixed read.t and wire.t to reference accept and reject.
 * Fixed reject.t not referencing accept command.
 * Fixed collect.t to more accurately reflect what goes on when collecting
    sectors.
 * Fixed financial.t to reflect defaulted loans.
 * Fixed dump.t, sdump.t, ldump.t, ndump.t, pdump.t to reflect new
    timestamp info.
 * Fixed "census.t" (had incorrect reference to "info syntax" instead
    of "info Syntax".

Changes to Empire 4.0.6 - Thu Jan 16 11:33 EST 1997
 * Increased damage from depthcharges because on increased damage from
    torpedos.  Sub frange decreased to be more balanced with destroyer frange.
 * Intelligence reports (spy) on units will now report the estimated number
    of mil on the unit.
 * Fixed equation for ship visibility so it will drop as tech increases.
 * Added new commands sdump, ldump, pdump, and ndump to dump data on ships,
    land units, planes, and nukes.
 * If fields are provided, dump will only supply those fields requested.
 * Decreased speed of subs.
 * When options NO_LCMS or NO_HCMS are set, those commodities are no longer
    required for infrastructure improvements.
 * Units that lose an assault or a boarding attempt from a ship will no
    longer swim back to the ship they came from.
 * Units that take extra casualties will no longer lose all their mil at
    once.
 * Infrastucture is retained when redesignating a sector.
 * Dieing spies will no longer crash the server.
 * Units, planes, and ships must have mobility to perform missions.
 * Units on ship being scrapped are transferred to harbor.
 * Food is no longer autoloaded onto units when they are built.
 * Fixed show plane stat to show correct range.
 * Infantries now take damage at same rate as casualties.
 * Fixed bug with hap_fact.  Having more happiness now helps with fighting
    che.
 * Fixed anti to write back target country so che will continue to fight
    when they survive.
 * Fixed llookout to show correct estimate on number of mil on unit.
 * Added buildable architecture "hp".  This type will build the server on
    a HP/UX machine using the standard compiler instead of gcc.

Changes to Empire 4.0.5 - Thu Dec 12 10:28:48 EST 1996
 * Fixed bug in update/distribute.c where pathcost was not being called with
    the MOB_ROAD argument (and thus distribution costs could be GREATLY
    affected.) - Thanks Ice!

Changes to Empire 4.0.4 - Mon Dec  9 11:00:00 EST 1996
 * Fixed Solaris port using gcc.
 * Fixed doconfig.c to create directories with right modes.
 * Fixed install macros in makefiles to move binaries to the right
    places.
	
Changes to Empire 4.0.3 - Wed Dec  4 22:46:53 EST 1996
 * Added HP/UX port.
 * Fixed doconfig.c (put exit(0) at the end of main.)
 * Fixed improve.c (moved the prompt[] string outside the fcn.)

Changes to Empire 4.0.2 - Mon Oct 14 12:26:40 EDT 1996
 * Put in LND_MINMOBCOST in land.h
 * Put in change in lnd_mobcost in lndsub.c
 * Put in new nuke costs in nuke.c
 * Put in fix so that total work can only be done by the max pop. No more extra
    civvies tossed in will do it anymore in human.c.
 * Put in fix for src/util/Makefile - beefed it up.
 * Put in fix to show where your ship is when it gets shelled in mfir.c.
 * Changed infrastructure of roads from .040 to .020 (122 instead of 150 in
    common/move.c)
 * Fixed Update-sequence.t.
 * Put in fix for mobcost bonus for 0% highways.
 * Fixed stop.t
 * Fixed commodity.t
 * Spruced up torpedo damage somewhat. :) :)
 * Fixed "assault bmap bug" in attsub.c
 * Fixed Produce.t (bars cost)
 * Changed mountains to get an automatic "2" for defensive bonus in attsub.c
 * Fixed consider.t
 * Fixed repay.t
 * Fixed offer.t
 * Fixed "offer" and "consider" not being legal commands in player/empmod.c
 * Fixed Damage.t
 * Fixed sstat.t
 * Fixed lstat.c, pstat.c and sstat.c
 * Fixed cutoff command in cuto.c
 * Fixed attack value in attack_val in lndsub.c
 * Fixed lload in commands/load.c
 * Fixed defense_val in lndsub.c - Made it a minimum of 1, so that units will
    always fight until dead or retreating.  0 makes them get stuck. 
 * Fixed update/deliver.c - no delivery of non-oldowned civvies (or anything
    else for that matter.)
 * Fixed llook in commands/look.c
 * Fixed che bug in subs/nstr.c
 * Fixed bug in strv.c by overcompensating by 1 food per sector (minute amounts
    of people would starve.)
 * Fixed update/human.c - feed_people rounding problems (I hope.)
 * Fixed morale problem in update/land.c
 * Fixed count_bodies in attsub.c
 * Fixed lnd_mobcost.
 * Fixed subs/land,plane,ship.c to handle sunken units and planes correctly.
 * Fixed interest rate in commands/offe.c
 * Fixed bug in buy.c.
 * Put in DEFENSE_INFRA soption o you can turn on/off the use of the defensive
    infrastructure.  When off, the defensive infrastructure is the same
    as the sector efficiency, and you can't improve it.  This is OFF by
    default.
 * Fixed Empire4.t
 * Added Wolfpack.t
 * Land units are now built with a default reaction radius of 0.
 * Changed name of lt artilleries to "lat" from "lart" so you can now build
    "lar"s again.
 * Lowered the speed and firing range of pt boats.
 * Lowered the initial att strength of cavs from 1.5 to 1.3 (they were TOO
    powerful.)
 * Changed the max mob gain defaults of units/planes to 1.0 and ships to 1.5
    (This is * ETU_RATE, so it is equal to ETU_RATE for units/planes and
     1.5 * ETU_RATE for ships.)
 * Conquered civvies only pay 1/4 taxes.
 * Railways don't get torn down when you rebuild sectors anymore (but roads
    and defenses do (if enabled.)

Changes to Empire 4.0.1 - Wed Aug 28 11:35:40 EDT 1996
 * Added "extern double tradetax" to check_trade in trad.c
 * Improved description of data directory in build.conf
 * Fixed bug in attacking land units that retreat so they now get
    charged mobility for attacking.
 * Fixed dump to report road, rail and defense of a sector at the end.
 * Fixed doconfig bug in not checking the right directory to see if the
    "data" directory existed or not before trying to create it.
 * "change" now works for sanctuary countries.
 * Fixed the description of "sinfrastructure".
 * Added more info to "Infrastructure".
 * Units/planes are no longer reduced to 75% when bought from the trading
    block.
 * Supply units were slowed down to the speed of infantry units.
 * Trade-ship payoffs have been lowered to 2.5, 3.5 and 5.0
 * Bars interest is up to $250 per 1K again.
 * Civ taxes were raised back up to a 10:1 mil/civ tax ratio (was 20:1)
 * Fixed various info pages.
 * Fixed bug in people not getting truncated when broke (this was thought
    to be fixed, but wasn't. Now it is, dammit!)
 * Fixed bug with units marching across oceans (scuba gear not included. ;-) )
 * Market/trade taxes and trade ship payoff figures were added to version.
 * "cede" has been removed as a default command.
 * Makefile rule was fixed for depend build.
 * Fixed bug in mapdist not taking world edges into account nicely enough.
 * Added a "scuttle" order for autoscuttling trade ships.  Makes using them
    easier.  Cleaned up scuttle code while in there.
 * Fixed bug with scuttling a ship with units on it not scuttling the units
    too.

Changes to Empire 4.0.0 - Initial release
 * Initial Wolfpack release - Long live the Wolfpack!!!!
 * Cleaned up the build environment.  Now all that is needed is to edit the
    build.conf file, answer the questions there and type "make " to
    build for a specific architecture.  Thus, no more reliance on gnumake
    or special shell scripts.
 * We are now shipping the pre-built info pages with the server for those who
    Don't want to build them.  You can also still just type "make" and have
    the info pages build, but it doesn't completely work (i.e. rebuild new
    Subjects) if you don't have perl5 installed.
 * Put in the "help" command that does the same thing as "info".
 * Removed C_SYNC.  This is done for 2 reasons.  1) None of us like it or
    wish to support it.  2) We envision a better scheme for doing similar
    things will come along.
 * Put in MOB_ACCESS - This allows real-time updating of mobility.
 * Put in MARKET - This is the time-based market (yes, still teleports,
    but it's not as bad as it was.)
 * Lots of the documenation has been updated, but there is more to do.
 * Added NO_LCMS, NO_HCMS and NO_OIL options.  When any of these options are
    enabled, you don't need any of that type of material to build things.
    If NO_HCMS is enabled, you don't need HCMS to build bridges, you need
    lcms.  If both NO_HCMS and NO_LCMS are enabled, then you don't need 
    any materials to build a bridge.
 * There is no mobility cost for assigning missions.  But, there is also
    no longer any benefit for being on a mission either.
 * Damage is the same for all commodities (people too.)  This means you
    can deity shell/bomb sectors again.
 * Units are now dependant on tech.  What this means is that their statistics
    now increase with tech.  In addition, there is only 1 type of each basic
    unit now (i.e. just "cavalry" instead of "cavalry 1", "cavalry 2", etc.)
    This reflects the idea that as you learn more, you learn how to not only
    build better units, but you learn to build units better. :)  This also
    opens the door for a "lupgrade" command along the same lines as the
    "upgrade" command for ships.
 * Units now have a minimum mob cost for attacking a sector.  Marching
    mob costs have not changed.
 * Starting units have been removed.  This means that at the beginning, people
    may live a little longer since their neighbor can't come visiting quite
    as quick.
 * Shells are no longer required to build units.
 * Mil are no longer required to build units.
 * Mil are no longer an intrinsic part of a unit.  They are now a loadable
    commodity.  The way a unit's defense/att bonuses work now are
        attack = (att * mil * eff)
        defense = (def * mil * eff)
    In addition, when a unit takes damage, both the eff and the mil go
    down.  You can quickly toss in new hacks, but you need to wait to repair
    the unit at the update.  Thus, you can now look at unit's efficiency
    as their training.
 * You need at least 1 mil on a unit to march it (spies are the exception.)
 * Units always react if in range and they have the mobility, no matter
    what their efficency.
 * Units may now march anywhere - in your own sectors, deity owned sectors
    or allied sectors, with 1 exception, spies.  Also, your units can get
    trapped if your ally declares non-alliance with you while your units
    are still in his country.)
 * Units always march at their speed, efficiency doesn't matter.
 * LANDSPIES was added - This creates land unit based spies.  Spies may march
    anywhere, with a chance of getting caught (except in allied territory.)
    See "info Spies" for more info on them.
 * Planes may now be based out of allied airports.  Landing planes on
    ships/sectors you do not own no longer changes thier owner.  You can only
    land on owned/allied sectors/ships, and you may only
    fly/bomb/para/recon/drop from owned/allied sectors.  So, if a country
    you are allied with goes hostile at you, your planes are now stuck there.
    Note that if you are using an allied airport, their commodities get
    sucked up, not yours (obviously.)
 * Planes are now tech-based.  Their statistics increase as their tech
    increases.  Deleted extraneous planes.
 * There is a new toggle, "techlists", which allows you to see what you
    can build/stats/capabilities sorted by tech instead of groupings.
 * Ships are now tech-based.  Their statistics increase as their tech
    increases.  Deleted extraneous ships.
 * Che can now be lessened by making happiness.  If you have more happiness
    than your conquered populace, they don't fight as hard or recruit as
    much.  If you have less than them, they fight harder and recruit more.
    It's not much though - it ranges from 2.0 in your favor to only 0.8 
    against you (whereas it was always 1.0 before.)  So, it definitely
    favors the attackers to make lots of happy now.
 * Bridgeheads can only be built on coasts.
 * Players command was fixed so you only see allies, and don't get
    approx #'s of players anymore.
 * POSIX threads support has been added.
 * The attack bmap bug has been fixed.
 * BTUs regenerate 3 times faster now.
 * GRAB_THINGS is off by default.
 * Big nuclear bombs are back, and FALLOUT has been fixed and enabled
    as a default (you couldn't make wasteland before with FALLOUT, now
    you can.)
 * You can now deliver military and civilians.
 * Added SHIP_DECAY option - off by default (turns off ships decaying out
    at sea if not enough mil.)
 * The reverting owner bug has been fixed in territory, thresh, dist
    and deliver.  There are probably more, and when found, will be fixed.
 * The "sectors don't starve when stopped or broke" bug has been fixed.
 * The "people never get truncated" bug has been fixed.
 * Added infrastructure to sectors.  What this means is that a sector
    can now have it's mobility improved by building both roads and
    railways.  It also means that a sectors defense is now based on the
    defensive infrastructure you build into the sector (no more intrinsic
    better defenses based on the sector, you determine which sectors are
    defended heavily, and which aren't.)
 * The defensive value of a sector no longer relies on the efficiency of
    the sector. Instead, it relies on the defensive efficiency of the sector.
    Thus, the "production" and "defensive" aspects of sectors have been
    separated.
 * "show sect stats" now shows the maximum defensive value for sectors.
 * Changed sector structure to take floats for off/def values so we can use
    a base of 1 instead of 2.
 * Added "improve" and "sinfrastructure" to support the infrastructure
    concepts.
 * Added L_TRAIN units which can only travel along railways.  Very fast on
    efficient railways, slow on non-efficient ones.
 * Added the ability for units to carry other units.
 * Fixed census (shortened up "fallout" and "coast" to "fall" and "coa".)
 * Forts only cost $500 to build and 100 hcms now (since they don't get any
    better defenses automagically.)
 * Modified "show sect build" to show the costs for building up the
    infrastructure of a sector.
 * Changed "spy" and the satellite recon stuff (which shows sector stuff for
    spyplanes too) to show the new infrastructure stuff, rounded of course.
 * Added Drake's info->html scripts, with some modifications, so you can
    now type "make html" and have your info pages built as html files too.
    This adds a new directory, "info.html", to the build tree.
 * Modified upgrade so that planes and land units may now be upgraded.
 * Added pstat command to list the statistics of your planes.
 * Added lstat command to list the statistics of your land units.
 * Added sstat command to list the statistics of your ships.
 * Added nmap command to show a map of your sectors after their new
    designations have taken place.

Comments from Dave Pare
.s1
I've been deity of seven or eight games,
and each time I learn something new about how far I should go,
and how active a role I should take.
.s1
There are several things a deity should take into account.
.in +\w'00)\0\0'u
.s1
.L 1)
Bug policy.
When a player says that a bug bit him, how do you handle it?
Since I used to hack on the game at the same time players would play,
I used to have a \*Qnasty\*U bug policy.
That is, if a bug bites a player, he loses.
It is very difficult to verify if a player
\*Qreally did lose those 1000 gold bars\*U from that bank
because of a bug.
Also, whenever a player had something bad happen to him,
he'd yell \*QBUG\*U.
All too often, the player just did something stupid.
.s1
If a player ever found a \*Qgood\*U bug
(and reported it in a timely fashion),
I'd give him some kind of reward.
The reward was generally material enough
to encourage them to report bugs,
but not too much so the other players complained.
If through use of this bug the player manufactured
\*Qtoo many\*U goodies for himself,
I acted to redress the balance immediately.
.s1
This whole case is only interesting
when the Deity knows the Empire code,
and can identify bugs as such.
.s1
.L 2)
Unskilled players.
It's tough watching your friends lose in an Empire game.
Helping \*Qjust a little\*U by giving information,
or by giving a teensy bit of assistance is BAD.
Empire is NOT a game of socialist care for the needy;
it's more like survival of the fittest.
Players should sink or swim on their own.
If you help a novice, you're deliberately hurting his opponent.
Some players will lose,
and as Deity you'll have to stand by and watch this happen.
.s1
.L 3)
Answering random prayers.
If you DO help someone, help them in relatively minor ways.
Do things like fill in some ocean, etc.
Don't give away commodities -- except perhaps food.
Whatever you do, don't give tech, military hardware,
civilians, military, or any information at all!
The game is very stingy with information, and you should be too.
.s1
.L 4)
Security.
Make SURE that nobody else has access to the data directories.
There are always players who will do anything to win.
If you help them control themselves
by making the data completely unavailable --
watch those dump tapes too --
you'll be doing their moral fiber and everyone else a favor.
.in
.s1
Remember, as Deity your job is to make the game fair.
Don't hose players
(unless they cheat -- and you catch them!)
and don't give out information.
Information is very important in Empire,
and as Deity you've got access to all of it.
Be careful in what you say,
and how you leave your terminal at night!
.s1
Unless you've got nothing else to do,
a Deity should keep player communications to a minimum.
Handling special player requests gets tedious after a while;
make players pay for Deity assistance.
One game I suggested that the only way players could get the Deity
to fill in ocean sectors, zap plague, etc,
was to offer a real-life sacrifice to the deity --
a few bottles of good beer, for example!
I got perhaps a dozen bottles,
and managed to greatly curtail player requests at the same time!
.s1
In summary, an Empire game should be between players.
Any time the Deity helps anyone,
Deity intervention starts becoming a factor in the game.
As a Deity, you absolutely can't go wrong
if you do nothing at all except routine game maintenance.

or if you receive a telegram.

It possible for contact to be one sided. If you contact someone, they must
also contact you in order to obtain information from you. If you want someone
to be able to contact you, you can send them a telegram.
.s1
Tech and research bleed only comes from contacted countries, so it's in your
best interest to explore as much as possible.
.s1
Because of the difficulty of tracking past news, news cannot be used
with an argument under this option. Once the news is read, it cannot be
read again. This may change in the future.
.s1
If the LOSE_CONTACT option is in play, contact is lost after three
update of no contact. Contact can be maintained by the same methods described
above. It's important to note, however, that contact is retained by RECEIVING
a telegram, not sending one.

1985 PSL Empire, Peter Langston

Naturally, the original creator (or at least the last surviving
implementor) of Empire is Peter Langston.  He distributed the
game that we all wanted to hack on, but naturally enough he
didn't give out the source!  (he wasn't dumb...he probably knew
what we'd do to his code)


1986 UCSD Empire 0.x, Dave Pare

Made Empire multiplayer with fixed update times.  Added hexmap, planes, nukes,
satellites, ships, market, distribute, and updates.

Jim Reuter (and his PDP/11 decompiler) provided Dave Pare with a large
quantity of amazingly readable decompiled code.  His contribution
came at a time when Dave's interest in reverse-engineering was
flagging, and it provided what was necessary to create the
original UCSD Empire.

David Muir Sharnoff was responsible for promoting the early
development of Empire 0.X.  Without David it is unlikely if Empire
would have escaped UCSD!  He took on the onerous task of managing
the source, creating mailing lists, applying patches, and generally
making the early versions of UCSD Empire releasable -- they
sure weren't when they left Dave Pare's hands...

The rest of the folks who contributed to the early versions did
so with code and/or ideas.  (If I've forgotten anyone, let me know!)
They appear in chronological order.

1986 BSD Empire 1.1, Dave Pare

The following people (listed in alphabetical order) have contributed
to the development of BSD Empire 1.1.  Without these people, BSD
Empire would never have happened.  Thanks also go to the XCF at the
University of California, Berkeley, for providing the facilities on
which we performed this herculean task.

			David Davis
			Steven Grady
			Jim Griffith
			Beorn Johnson
			Phil Lapsley
			Jonathan Lee

198? UCB Empire 1.2, ??

Added announcements, food, removed weather, parks, petrol,
edu, terrorists, shoot, many new ships.


198? BSD Empire -- KSU Distribution (1.04), Jeff Bailey

One of the goals of the KSU team was to make the server as
configureable as possible.  As such, they added many OPTIONS, and
global constants.  Added abms, asats, bmap, autonav, scuttle,
NUKEFAILDETONATE, MISSINGMISSILES, SHIPNAMES, NEUTRON, RANGEEDIT,
MISSDEF, NOFOOD, UPDATESCHED, DEMANDUPDATE, ORBIT, FALLOUT, SAIL,
ALLYHARBOR, and fixed many bugs.  Other contributers were:
			Yaser Doleh
			Robert Forsman
			Doug Hay
			Alex Shatsky


198? Merc Empire ?.?, ??

Fixed many bugs and removed loans, added grind, starvation, and prod.


1992 Chainsaw Empire 1.0, Thomas Ruschak

Added land units, SUPER_BARS, EASY_BRIDGES, SLOW_WAR.


1992 Chainsaw Empire 2.0, Thomas Ruschak

Added trade ships, fuel, semiland ships, ASW planes, payoff, wire, SNEAK_ATTACK
retreat paths, sweep planes, budget.  Tom thanks the following people
for helping him with ideas and playtesting:

			Jorge Diaz (Ansalon)
			Tom Tedrick (Afrika Korps)
			Keith Graham (DreamLands),

			Sasha Mikheev (Dolgopa)
			Baldric
			Elsinore
			Brett Reid (Resvon)
			Sam Tetherow (Kazzad'ur)

range bonus for 60% forts, cede, neweff, starva, forts interdict
ships, mountain caps, RES_POP, NEW_STARVE, NEW_WORK, uncrewed ship
decay, anonymous sublaunched missiles, stop & start, bdes.


1995 Empire 2.0, Dave Pare

emp_player, emp_tm, and emp_update, were consolidated into one program
called emp_server.  A threads package called "lwp threads" was used to
manage the player threads.  Many options were made standard.  Kevin Klemmick
added HIDDEN and NEWPAF options.  Many options were made standard.
These are the people who submitted patches for Empire 2.0:
			Chad Zabel (3 letter abbrev's, & autonav)
			Ken Huisman
			Scott Ferguson (linux port)
			Kevin Klemmick
			Doug Hay (threads debugging)
			Bill Canning (AIX port)
			Julian Onions


1995 Empire 2.1 beta, Ken Stevens

Organized info pages, wrote a "configure" script, made minor
improvements to many commands, rewrote missile, navigation, and march
code.  Consolidated launch/bomb and missile/plane interdiction so that
hitchance and damage is the same whether it's a mission or done "by
hand".  Added collateral damage, interdiction nuke detonation,
"friendly" trade relations, BIG_CITY, ATT_INTERDICT, 
Consolidated sail, navi, and order.  Added toggle, flash, wall,
shutdown, strength.  Other contributers:

1995 Empire 2.2 beta, Ken Stevens

Completely rewrote attack, assault, board, and paradrop.  Added
"players", "skywatch", "disarm", tend land units.  Other contributers:
			Craig Leres
			Janjaap van Velthooven (IRIX port)

1995 Empire 2.3, Ken Stevens

After running a series of playtest games, Ken fixed all known bugs in
the server, organized and rewrote alot of documentation (including
this info page) and released the Empire2 server out of beta.

1995 Empire 3.0, Ken Stevens

Empire 3.0 implemented the C_SYNC RFC, a powerful platform independent
client-server protocol for synchronizing the client database with the
server database.  The Empire 3.0 server was released with the Empire
Toolkit written by Kevin Morgan, a portable C library which parses the
C_SYNC messages from the server into a database for the client.  Thus,
clients can link with the Empire Toolkit and be confident that when
the server gets upgraded, their client will still work.  Note that the
C_SYNC protocol is asynchronous so, in particular, players will be
able to watch their neighbours sail ships past their coast etc...

1996 Empire 4.0, Wolfpack (http://www.empire.cx)

A group of people got together to form a new server project.  This project
is a new project, and is a complete takeoff from the Empire 3.0 server
project.  There are many additions and some subtractions from the 3.0
code base.  The Wolfpack is headed up by Steve McClure and consists of the
following people:

                        Mark Ballinger
                        Geoff Cashman
                        Bill Frolick
                        William S. Kaster
                        Pat Loney
                        Steve McClure
                        Richard Moss
                        Walter Smith
                        Sam Tetherow
                        Yannick Trembley
                        John Yockey

1998 Empire 4.2, Wolfpack (http://www.empire.cx)

The above authors (Dave Pare, Jeff Bailey, Thomas Rushack, Ken Stevens
and Steve McClure) agreed to re-release the source code under the GNU
GPL.  The source was already freely released to the public, but any
copyright issues (such as gaining permission from Phil Lapsley for the
A* code and removing any other copyrighted code which would violate
the GPL) were cleared up, and the licensing information was put in
place to keep the server source free forever.  Yee-haw!

In addition, the server was made run-time configurable (yes, including
WORLD_X and WORLD_Y) so that you didn't have to re-build an entire server
each time you changed an option (you just have to rebuild the world 
sometimes. ;-) )

The source is still managed by the Wolfpack team, and still headed
up by Steve McClure.

.NA Merc "Changes from KSU code to Merc code"
.LV Expert
.s1
There have been several changes/fixes made to the KSU code for
the Merc V game.  This will outline the various changes and how
they will affect you.

Bridges

There was a bug which allowed planes that were on bridges that collapsed
to remain in the sea sector and could be retrieved by either rebuilding
the bridge or moving them onto a 100% highway.  This has been fixed so
that any planes upon a bridgespan which falls will be destroyed.

Uncompensated Workers

Uncompensated workers were not paying taxes, even though the version command
provided a tax rate for them.  They now pay the taxes that are shown.

.SY "reject reject announcements *"

This command now works, so that you can reject announcements from
everybody.  This is not recommended though...

Technology

The tech formula has been fixed so that all increases in material
result in an increase in the amount of tech produced.

.NF
	if(breakthroughs > 0.75) {
		above = breakthroughs - 0.75;
		tech = 0.75 + log2(1 + above);
	}
	else {
		tech = breakthroughs;
	}
.FI

Grind

The grind command now requires available work to grind up bars.
It takes 5 avail to grind up a gold bar.

Loans

Loans have been removed from Merc V.  This is an experiment to see
how things go without loans being available.

Country Names

Certain commands only worked with country numbers, but they now work
with country names as well.  The primary command that this affects for
Merc V is report.

Production

The production of dust/oil/rads is now limited to the resource content
of the sector.  It used to be possible to get more out of a sector.,

Starvation

Sectors that have a very large number of civilians that starve will
have at most 499 civilians after the update unless there was enough food
to feed more than 499 civs.

Attack

The attack command now uses at least 1 mobility point per sector that
participates in any attack.

Pinpoint Bombing

Pinpoint bombing now lists all the commodities in a sector that can
be bombed.

Production Report

The production report now contains a report of what will actually be produced
by your sectors at the next update.  Since some of the rounding done by the
update code uses a random percentage chance, it is possible that you will get
1-2 units more of some of the items.  The production report command is
conservative, and assumes that all rounding will be down.

Version

The information in the version command was modified so that the information
that was printed out would reflect the actual parameters of the game.

\*(bFUCB Empire Version 0.9.24 - Update for Version 1.2 Players\*(pF
.s1
So you want to try the New Empire Huh?
.s1
Okay, I have written this document with YOU in mind!
Welcome to the University of California at Berkeley's Empire!
(From now on called UCB Empire).
There are a whole bunch of changes in the game 
since we last played, so I need to bring you up to date.
.s1
Our OLD EMPIRE game was Version 1.2 -
written way back in the 70's by Peter Langston,
when he was going to College like we are!
But Empire has come along way since then -
and what many have considered the REAL EMPIRE was released in 1985 -
containing the final version of Peter Langston's Empire game.
It still is considered the \*QStandard\*U.
But in 1986 the \*Qcomputer brains\*U at Berkeley
decided to play around with the Source Code
and create their own \*Qenhanced\*U version of the game.
Hence \*QBerkeley Empire\*U was created....
.s1
.ce
\*(bFChanges from Version 1.2\*(pF
.s1
(Please keep in mind that these are only a FEW on the changes -
you're going to have to read the Manual and use the INFO command
to get a REAL good idea on what you should read up on -
DON'T depend on this list to tell you everything you need to know)
.s1
There is an \*Qannounce\*U command -
this command sends a Telegram to EVERYONE in the game -
and you can make an \*Qannouncement\*U to the World.
.s1
In the OLD game -
you simply dug up ORE and sent it to the Shell, Defense, etc.
factory to have it processed into something else
(make guns, shells, etc).  
.s1
But in the NEW game - sectors are a lot more complex.
For one thing curtain sectors CAN'T even PRODUCE
until your country has reached a given TECH level.
These sectors are currently:
.s1
Shell Factories  (need at least 20 TECH)
Gun Factories  (need at least 20 TECH)
Petroleum Plants [ for Airplane Fuel ] (need at least 20 TECH)
Uranium Mines   (need at least 40 TECH)
.s1
Other sectors can produce normally,
even though your TECH level is still 0.
Keep in mind that you CAN DESIGNATE the ABOVE sectors -
but they won't produce until you reach the desired TECH LEVEL. 
.s1
Also, it takes more \*QMaterials\*U
to make 1 Unit of a finished product.
By this I mean that to make approximately \*Q1 SHELL\*U
at your shell factory, you'd have to have:
3 Dollars (in the treasury),
2 LCM, 1 HCM, and at least 20 TECH Level.
.s1
LCM is Light Construction Materials,
HCM is Heavy Construction Materials,
and I discussed the TECH Level problem (above).
To fully understand this concept -
please see \*Qinfo Products\*U and \*Qinfo Sector-types\*U.
.s1
FORTS - have been improved.
It used to be in OLD Empire that you had to use the DEFEND command
to say which sectors you wanted to DEFEND with the guns from your fort.
But in the NEW Empire -
your forts will fire on ANY enemy attacker
as long as the attacker is within the guns'
range when the \*Qattack\*U was made.
Hence - no more DEFEND command.
.s1
FOOD - In the OLD Empire you didn't have to worry about it -
the people fed themselves.
But in the NEW Empire -
there is a new sector designation called \*Qa\*U for agribusiness.
These are farms that make food and you have to transport that food
to other sectors that don't grow food or those sectors will starve.
**NOTE** that in the \*QFERTILITY\*U rating in the \*QCENSUS\*U report -
only those with HIGH Fertility ratings can successfully grow food.
If the FERTILITY rating is in the 10-30% - BE CAREFUL - they
may not be able to grow enough food to sustain even themselves!
Food is also a great Commodity to \*QSELL\*U (hint,hint!)
.s1
WEATHER - There ISN'T ANY!
(no more rainy days :-)
Although judging from the way Berkeley has been improving the game -
it won't be long till they do fix it.
Can you imagine what weather will be like if they update it
like the did the \*Qplanes\*U!
Thunderstorms, tornadoes, hurricanes, earthquakes, volcanos, etc.
BUT FOR NOW - THERE IS NO WEATHER - Atmosphere is stuck at
\*Q0\*U - clear days!
.s1
NEXT UPDATE (how will I know when it is supposed to Happen?) -
EMPIRE will always tell you when the NEXT UPDATE is scheduled
by using the VERSION command.
VERSION will also tell you how much food will grow per-update and
also things like - how much food you people eat per update - etc.
.s1
MAP CHANGES -
in the OLD Empire you could move u)p, l)eft, r)ight, d)own, etc -
but now you have to move in DIAGONALS -
you'll get used to it -
the world is set up like this so the game can handle
more SECTORS per world.
Basically means that the MAP display is more condensed -
and you'll be able to see more sectors on a MAP display
than ever before.
.NF +0.2i
A few new SECTOR-DESIGNATIONS have been added:

    BASICS                   INDUSTRIES                MILITARY / SCIENTIFIC
    .  sea                   d  defense plant          t  technical center

    /  wasteland             g  gold mine              n  nuclear plant
    -  wilderness            h  harbor                 l  library/school

    +  highway               a  agribusiness           b  bank
    )  radar installation    o  oil field
                             j  light manufacturing
    #  bridge head           k  heavy manufacturing
    =  bridge span           %  refinery
.FI
PLEASE!
Fully READ the \*Qinfo Sector-types\*U
.s1
I haven't got time to go through all of them -
but I will point out a few of them that might be unfamiliar to you.
.s1
PARKS - these are special because they convince your people that
they should ENLIST and go out and fight for you!
Lots of fun - gotta have one of these to keep the ENLISTMENT rate high.
.s1
URANIUM MINE - I forgot to add this above with the other Commodities -
with the Commodities \*QFERTILITY\*U, \*QOIL\*U, \*QGOLD\*U,
\*QMINE\*U -
there is also \*QURANIUM\*U.
Uranium is the most UNCOMMON natural resource
and hence those that have a deposit of it
should be careful to guard it well.
When URANIUM is dug up it becomes \*Qradioactive Matter\*U -
you then deliver the Radioactive Matter to the Nuclear Plant
and have it converted into - you guessed it - NUKES!
Be aware, however, that you must have a HIGH Tech level
to make nukes -
and it is going to take you a LONG TIME to get to this point.
.s1
REFINERY SECTORS: These are where the OIL you make
is turned into PETROL(-eum) for your various AIRPLANE needs.
Planes run on PETROL and the refinery sectors make PETROL out of OIL.
You then have to deliver the PETROL to your Airports for use...
.s1
LIBRARY/SCHOOL:  Obviously your people aren't very smart :-)
As it is your going to need to educated them.
Education will increase CROP yields and also help with TECHNOLOGY.
see \*Qinfo education\*U.
.s1
.ce 1
\*(bFWorld Updates\*(pF
.s1
In the OLD EMPIRE - updates weren't handled in a FAIR way.
If you created a 0% FORT before you logged out of Empire -
it would REMAIN a 0% FORT until you logged back into Empire -
and if your on a LONG weekend that could have meant
that you would be WIPED OUT!!!!
.s1
In the NEW EMPIRE -
updates are handled by an independent program
called the \*QTransaction Manager\*U.
This program runs independently of EMPIRE
and runs at 4 hours intervals,
updating the game constantly.
That means that you enemies will be updated just as often as you ARE -
and may make them think a little more carefully about attacking you.
The CURRENT update times are:
.s1
2am, 6am, 10am, 2pm, 6pm, 10pm (In the local time zone)
.s1
NO OTHER UPDATES ARE POSSIBLE - except at these times.
What is updated is all Mobility, Food Production,
Shell & Factory Production, Ship Plane and Sector Efficiency,
and EVERYTHING that \*Qupdate\*U used to do.
(hence there is NO Update Command).
Everyone is updated at the SAME TIME!
.s1
.ce
\*(bFOther Things That Might be of Interest\*(pF
.s1
Terrorists!  -
(real trouble makers, but great for setting on your enemies -
they blow up things and convert followers!)
.s1
SHOOT - it is now possible to SHOOT your civilians
(captured enemy ones) or your own :-)
God knows why you would but...
sometimes the conquered people are REAL radical
and it DOES become necessary
.s1
SELL - you can sell your goods on the OPEN Market -
and set PRICE MULTIPLIERS so that your enemies
HAVE to buy at a BIG mark up -
but your friends can still buy your good cheap!
.s1
Okay - you've been waiting for it - so here it is!

A  banner  line  saying  ANNOUNCEMENT  is  prepended  to  your message so that
announcements won't be  confused  with  telegrams.   In  all  other  respects,
announcements are exactly the same as telegrams.

NAME
   anti - anti-terrorist actions

Level: Basic

SYNTAX
   [##:##]% anti 

 The  anti-guerrilla  command is used to remove che from any sector.  The com-
mand take the following form:
   [##:##] Command: anti 

Once issued, the strength of the che is compared to the number of mil  in  the
sector.   The  maximum number of mil allowed to fight is equal to the mobility
in the sector.  Che recieve a combat multiplier which may or may not make them
tougher to kill.  There are only three outcomes for this command.

      1)  The mil kill all the che.  The sector is cleared (for now).
      2)  The che kill the mil.  The sector then returns to the old owner with
          most or all of the che reverting to mil.  The old owner is sent a
          telegram informing him of the event.
      3)  The battle is suspended when the mobility in the sector is used up.
          Each mil or che killed uses one mobility point.

Units  do not participate in the anti command.  A sector can revert to the old
owner while your units are stuck in it.

Note that che are finicky.  If you manage to lose a sector fighting them, they
do  unpredictable  things.   They may all come out of hiding to join the mili-
tary.  A few may stay in hiding while the majority come out to join the  mili-
tary.  Who knows what else they may do.

Level: Basic

SYNTAX
   [##:##]% apropos  [maxhits]

The  Empire  info  pages are organized by subject. It can sometimes be hard to
find the exact page with the information in which you are interested.  To  get
a list of subjects containing the word you are looking for, type:
   [##:##] Command: apropos 

without the < and > brackets.

You can then type:
   [##:##] Command: apropos bridge
to  get  a  list  of  Empire  commands  and info topics which contain the word
bridge, as well as the line that mentions it.

Apropos is not case sensitive, thus the above example  will  find  pages  with
Bridge or bridge (or even bRiDgE).

By  default, apropos exits when 100 hits are found.  You can change this value
with an optional second parameter.

NAME
   arm - Load nuclear weapons onto planes or missiles

Level: Expert

SYNTAX
   [##:##]% arm   

The  arm  command loads nuclear devices aboard delivery systems such as planes
or missiles.

No nuclear weapons can be delivered unless they are first loaded aboard deliv-
ery  vehicles.   However,  until they are residing in a plane or missile, they
are considered invulnerable to attack (buried inside of mountains), and cannot
be used by any potential conqueror (they don't know the fail-safe codes).

You  decide  whether  the warhead will airburst or groundburst at the time you
arm it.  If you'd like to change airburst/groundburst later on, just  arm  the
plane/missile  again (in this case, the second argument will be ignored).  You
can see whether a nuke will air or ground burst using the "plane" command.

NAME
   army - Designate members of an army

Level: Expert

SYNTAX
   [##:##]% army  

The army command is used to specify the army groupings of your units.

   [##:##] Command: army  
In the syntax  is the alphabetic character to be used as the army desig-
nation.  This character can be chosen from the set of upper or lower case  a-z
and  tilde  (~).   The pseudo-army specification tilde specifies all units not
currently in any army.

The specification of units, , can have one of several syntaxes:

   example     meaning
   -------     -------
   23          unit 23
   2/14/23     units 2, 14, and 23
   c           all units currently in army `c'
   ~           all units currently in the null army
   2,3         all units in sector 2,3
   -1:3,0:2    all units in the square area bounded by -1,0 & 3,2

All armies, (with the exception of the `~' army), are limited to some  maximum
size and you will be informed how many units can be added when this command is
run.

Having units organized into armies can be very  helpful  in  loading,  moving,
etc.,  in that fewer commands are required to perform these commands on groups
of units if they can be specified by army number.

Note that you can remove units from a army by adding them  to  the  `~'  army.
e.g.
   [##:##] Command: army ~ A
This command would purge all units from army `A'.

NAME
   assault - Attack coastal sector from ship

Level: Basic

SYNTAX
   [##:##]% assault   [   ]

The  assault  command  allows your marines to hit the beaches.  It is also the
only way to get ashore other than by unloading at a harbor,  thus  it  is  the
first step to gaining land on a new continent.

Any  ship  with military can assault a sector containing 0 mil, however only a
landing ship can assault a sector with military in it with its full complement
of  troops.   The  other  ships  will only be able to land a fraction of their
troops in any given assault (usually 1/10th).  This represents the use of  the
Admiral's gig, the Captain's barge, etc.

Note that some ships will have the semi-lander flag, which allows them to land
25% of their troops.

If you have land units with the 'assault' ability aboard the ship  assaulting,
you will be asked if you wish them to join in the assault as well.  Assaulting
land units go to negative mobility when assaulting.  (by an  amount  equal  to
the  mobility  gain  per  update)  Marine  units go to 0 mobility instead.  If
assaulting from a ship with the landing ability, a normal unit pays  only  mob
equal  to  1  update's  worth of mobility. A marine unit pays 1/2 that amount.
(Example: in a game where land units gain 32 mobility per update, a non-marine
unit would pay 32 mobility to assault from a landing ship. A marine unit would
pay only 16 mobility)

NOTE  This mobility loss for units happens whether or not you own  the  sector
being  assaulted.  If  you wish to land troops without suffering this penalty,
make/capture a harbor!

If you have ship #28 bearing 10 military at 31,53 it can assault land  at  any
of the adjacent sectors, (32,52; 33,53; 32,54; 30,54; 29,53; or 30,52).

For example:
   [##:##] Command: assault 32,54 28

This  command asks to assault sector 32,54 from ship #28.  If you assault with
9 troops and assuming the sector has no military,  and  since  there  were  10
troops  on  the ship to begin with, 90% of the food will be taken along by the
assaulting troops, (and each one that makes it will contribute his or her  10%
to  the  conquered sector). A minimum of 1 food will be left on the ship. Land
units will not take any food from the ship, and will only have the  food  they
are carrying.

You  will  be  asked for any information which was not included on the command
line, (sector to be assaulted, which ship is doing the assaulting,  number  of
brave troops to disembark, land units to use).

The offensive value of assaulting units is cut in half to represent the diffi-
culty of getting to shore, except for "marine" units  whihc  assault  at  full
strength.

Units  may not retreat from an assault, and will take extra casualties instead
if they fail a morale check.

Other than these factors, assault is the same  as  normal  land  combat,  with
forts/units/ships/planes  firing  on both sides to support, etc. Support argu-
ments are also as in attacking.

See info Attack for the exact procedure. The sector being assaulted will  have
exactly the same reaction to being conquered as if it were attacked by land.

You  may  assault your own sectors. In this case, the assaulting mil are added
to the mil in the sector, and assaulting land units simply come ashore.

You may also use assault to sneak spies on land.  To do this, you must assault
with  spies  only,  and  they will try and sneak on land. See "info Spies" for
more information.

NAME
   bdes - Manually change your bmap

Level: Expert

SYNTAX
   [##:##]% bdes  

A  bmap  gives  you  a  graphic representation of all or part of your country.
Bdes allows you to change a sector of your bmap.

Bmap differs from map in that it reflects everything you've learned about  the
world.  If, for example, you navigate near a sector and find out that it is as
sea, it will show up on your bmap as sea, even if it doesn't show up  on  your
map.

When  you  get  new  information, it will overwrite the designation you put in
with bdes, UNLESS you put in an 'x' or an 'X'. These two characters,  'x'  and
'X'  are permanent, unless you manually change them with bdes. Once you change
them back, the sector will be updated normally by nav, march, etc.  (The  nor-
mal  use  for these is to record minefields, so that you can march adjacent to
the minefield without eliminating the information)

Unlike normal designation, with bdes, you may use any character.  If you  wish
to use a space, surround it with double quotes: bdes # " "

You can't bdesignate something to a ?

Conditionals  do  not work with bdes (i.e. bdes # ?des=c C) unless you own the
sector.

Note that the bdes command only changes  your  'working'  bmap  and  not  your
'true'  bmap.   If  you  make  a mistake and bdes a bunch of sectors where you
didn't want them to be, you can always start over by typing
   [##:##] Command: bmap revert
which will revert your 'working' bmap back to your 'true' bmap.

The bestpath & bestdistpath commands show you the best path from any sector to
any sector. You must own both sectors.

The path shown by bestpath is the cheapest owned existing  path  in  terms  of
mobility.

Bestdistpath  shows the best distribution path that can be found, which should
be the same as the best path..  During the update, sectors distribute  to  and
from  their distribution point by means of the best distribution path they can
find at that time.

Note that if you give these commands areas, they will  show  you  more  paths.
For example,

   [##:##] Command: bestpath #1 #2

will  show  the  best  paths from all sectors in realm 1 to all the sectors in
realm 2.

SYNTAX

A bmap gives you a graphic representation of all or part of your country.

Bmap  differs from map in that it reflects everything you've learned about the
world. If, for example, you navigate near a sector and find  out  that  it  is
sea,  it  will show up on your bmap as sea, even if it doesn't show up on your
map.

Note that bmap shows the LAST KNOWN INFORMATION you have about  a  sector.  It
may  change,  and your bmap will not reflect it. For example, if you re-desig-
nate a sector, it won't show up on your bmap as the new sector type until  you
do a map.

Commands contributing to bmap include (but are not limited to): map, nav, fly,
bomb, recon, para, drop, lookout, coastwatch, radar.  (probably others)

Your own sectors show up as a designation mnemonic  (see  Sector-types)  while
sectors  held  by  other  countries  appear as question marks (?).  Mountains,
wilderness areas, and seas appear as '^', '-' and '.' respectively.

Note that any sector marked as 'X' on your bmap will automatically be  avoided
by  ships  when they are trying to calculate the best path between two points.
Whenever you detect a sea mine in a sector, the server will automatically  put
an 'X' on your bmap.

You can call up a local bmap while navigating or marching by typing 'B' at the
prompt.

Examples:
   [##:##] Command: bmap -9:18,-8:5
generates a 28 x 14 bmap based on data supplied by the  sectors  in  the  area
specified.

   [##:##] Command: bmap # >mapfil
where  your  realm  (or  '#', see info realm or info update) is -5:5,-6:6 will
type out a 11 by 13 sector bmap and also put the bmap in the file called  map-
fil.

You  can  also  give the number of a ship, and bmap will give you a small bmap
centered on the location of that ship, provided you own it.  If you use  lmap,
the  number of a land unit will give you a map around that land unit. The pmap
command does the same for planes.

BMAP FLAGS

If you specify an 's' flag, bmap will put your ships on the map.  If you spec-
ify  an 'l' flag, bmap will put your land units on the map.  If you specify an
'p' flag, bmap will put your planes on the map.  A '*' will  put  all  on  the
map.

You  actually have two bmaps.  One which is created by the server; this one is
called your 'true' bmap.  You can view your true bmap at any time using the

SYNTAX
   [##:##]% bmap  true

command.  However, usually when you view your bmap, you are  looking  at  your
'working'  bmap.   The only difference between your working bmap and your true
bmap is that your working bmap also contains designations put on there by  you
using  the  'bdes' command, and by your friends using the "sharebmap" command.
If somehow your bmap gets corrupted, you can revert your working bmap back  to
your true bmap using the command:

NAME
   board - Board enemy ship

Level: Basic

SYNTAX
   [##:##]% board [] [ | ]

The  board  command enables two ships' crews to engage in hand-to-hand combat.
To board ship #16 from ship #93 you might type:
   [##:##] Command: board 16

The program will ask from which ship or sector you wish  to  board,  (you  may
only  board from one ship at a time), how many troops to board with, and which
land units (having "assault" capability) to board with.

In order to be able to board a ship from a ship, your ship must be as fast  or
faster  than the defending ship.  If you can't catch him, you can't board him!

The attacking ship will use, based upon its speed, an amount  of  mobility  to
overtake and board the target ship.  If the attacking ship has no mobility, it
cannot catch anybody!  Ships' speed depends upon the speed of  the  ship,  the
technology  of  the owner, and the current efficiency of the ship.  A 50% dam-
aged ship moves one-half the speed it does when undamaged.

In order to board a ship from a sector, the ship must be in  the  sector,  and
either  the  sector must have mobility or it must contain some land units with
the "assault" capability.

Some things to note:

The defense strength is multiplied by 1 + def/100 where  def  is  the  defense
strength of the ship (see show ship stats).

Other  ships  belonging  to the victim will fire on you when you try to board,
(if you're within range).

Any land units in the combat will fight as if they were simply mil, i.e.  they
won't  get  any  offensive  of defensive multiplier, except for "marine" units
which get their full bonus.  Similarly, units on  ships  don't  have  to  take
morale checks, as they are fighting as mil.  Mil on the victim ship will still
die before units take casualties, however.

Note that you can only board with as many mil and land units that the ship you
are trying to board can hold.

See info Attack for the exact procedure.

NAME
   bomb - Dispose of inconvenient enemy assets with airpower.

Level: Basic

SYNTAX
   [##:##]% bomb   mission-type  route|destination

The  bomb  command  is  used  to  rain  destruction upon helpless enemy ships,
planes, and sectors.  It represents a complete mission for one or more bombers
and  escorts taking off from one place and returning to base at the end of the
mission.

 represents a list of planes which  can  carry  bombs.   Only  planes
which  have  a  bomb  bay,  belong  in  a sector which is stocked with gas and
shells, and have sufficient mobility will be  successfully  selected  for  the
mission.

  represent  a  list of fighter planes which are capable of escorting
the bombers all the way to the target.  To be selected, escorts must have fuel
and mobility.

Mission-type  must be one of "pinpoint" or "strategic".  Each mission has dif-
ferent objectives for the  planes  performing  it.   Pinpoint  missions  allow
bombers to attack ships, sector efficiency, commodities in sectors, and planes
on the ground in the target sector.  Strategic missions damage all commodities
in  the  entire target sector, while not damaging any ships or planes resident
(similar to the ship and sector fire missions).  If a plane is  armed  with  a
nuclear  warhead,  then  it  will drop the bomb rather than using conventional
weapons.  Nuclear devices damage everything in the sector; planes, ships,  and
commodities.   Only missiles in hardened silos can avoid damage from a nuclear
mission.

 represents an assembly point, where all of the planes  in  the  mission
meet  before  proceeding  on to the target sector.  The assembly point must be
owned by you, and must not be more than four sectors  away  from  any  of  the
planes selected for the mission.

Route  is  a normal empire path specification. You may also give a destination
sector on the command line, or at any time while giving the route, and  empire
will use the best path from the current sector to the desired destination sec-
tor.

When getting a path interactively, empire will show you a small map (from your
bmap) concerning the current area, to help you plot your course.

Light  bombers  (with the tactical capability) are used primarily for pinpoint
bombing.  They perform as well as fighters do for  strategic  bombing.   Heavy
bombers (with the bomber capability), while they can perform pinpoint bombing,
are notoriously inaccurate and in general miss what they are aiming at.   They
are used mainly for strategic bombing.

During  the course of a mission, your planes may fly over someone else's land.
If you fly over land owned by another country, and this country is either hos-
tile or in any war state (see info relation) with you, fighter planes from the
enemy country will scramble and attempt to intercept your force.  If the coun-
try  is simply neutral, he will be notified that his radar tracked your planes
as they flew over his country.  If the country is allied,  then  nothing  will
occur.

If you manage to fight though the enemy fighters and arrive at the target sec-
tor, your force must still contend with any flak guns  which  your  enemy  has
stationed  there.   What's more, any enemy ship in the target sector will also
shoot at each of your bombers before any attacks  are  performed.   Any  enemy
land  units  with the 'flak' ability will also fire at all your planes at this
time.

A well-equipped fleet of battleships in a heavily-defended harbor can be  very
risky  to attack, even though hitting ships in harbor is like shooting fish in
a barrel.

When bombing ships/planes/units, entering a '~' character will cause a partic-
ular  plane  not  to bomb. Other planes on the mission will still be asked for
their targets.

If your plane has anti-submarine (asw) capabilities, you will be told when you
arrive in a sector whether it has submarines in it. If you then choose to pin-
bomb ships, each plane in turn will attempt to find submarines  (this  ability
varies  with  the plane's accuracy rating).  Each plane can only bomb the subs
it can find. (It is assumed that planes on anti-sub missions split up to cover
the area)

Planes have differing air-to-air combat abilities, differing ranges, and load-
carrying capacities.  Some airplanes don't need runways, but can  operate  out
of any sector which has fuel in it.

ASW  capable planes may attempt to fly pin-bombing missions versus submarines.
To do this, the plane gives a target sector, and flies there. If there are any
subs  in  the sector, a message will be printed saying that. If the plane then
attempts to bomb ships, it may get the chance to bomb subs in the sector.

The chance to detect a sub is the same as the chance of hitting it.

If the plane does not detect a particular sub, it may not bomb it on that mis-
sion. On other missions, it could roll again.

Trying  to  pinpoint  bomb land units is similar to trying to bomb a sub.  The
chance to find the unit to bomb it is based on the  unit's  visibility  &  the
type of the sector it is in.

When  you  pin-bomb  a  land  unit, it will fire flak at the plane bombing it,
unless it is an 'flak' unit (in which case it fired earlier), or it has an  AA
fire rating of 0.

In  the  case  of  pinbombing,  see info Hitchance for the formula determining
whether a plane hits its target.

Note that a plane must be at least 40%  efficient  before  it  can  leave  the
ground.

Budget  with  an argument sets the priority of the given sector type (or L for
unit building, or A for unit maintenance, or P for plane building,  or  S  for
ship  building, or M for ship maintenance, or N for plane maintenance, or C to
clear all)

Priorities are a positive number, or 0, or ~.

By default, budget lists only items which cost something. Non-producing  items
will be listed if they are given a priority.

Update order:

Please see info Update-sequence for more details on the order things happen in
during the update..

Turning sectors off

Sector designations (or ship or plane building) with a  0  priority  will  not
produce, build efficiency, or gain avail.

If  a sector of a type with 0 priority has been re-designated, the sector will
be torn down and rebuilt as usual (and may produce as well, depending  on  the
amount of work available, as normal)

If  a  sector  of  a type with a non-zero priority has been re-designated to a
type with a 0 priority, the sector will be torn down to 0%, and  the  designa-
tion changed, but no further work will be done.

For  other ways to control sector production, see the start and stop commands.

Costs for each sector type include costs for building efficiency in sectors of
that type. (This is true even if the sector will change to a different type as
a result of that work. For example, costs for libraries will include all costs
for  work  done in library sectors, even if one of the sectors is being turned
into an aggie)

Estimated Delta

The estimated delta may not be correct, due to events during updates.   (star-
vation, plague, sector revolts, etc).

Budget  takes  into  account  avail in headquarters, harbors and airports, and
will only show you how much you'll pay for work that will actually get done in
cases  where  your headquarters/airports/harbors will not have enough avail to
work on all units/planes/ships.

If a cost is in [ brackets ], then that means that you will not pay it because
you  will not have enough money.  If a cost is in ( brakets ), then that means
that you will not pay it because you have chosen not to pay  that  cost  (i.e.
you have set the priority of that item to 0).

NAME
   build - Build ships, planes, bridges, land units or nuclear weapons

Level: Basic

SYNTAX
   [##:##]%   build   [land|ship|plane|nuke|bridge]    [unit-type|ship-
type|plane-type|nuke-type|direction] [Number to build] [tech] [sure?]

The build command is used to specify the types of units to be  built  at  your
headquarters,  ships  to  be built in your harbors, the planes and missiles at
your airfields, the nuclear devices at your nuclear production facilities, and
the directions in which bridge spans are to be built.

The  ability  to  produce units, ships, planes, nukes, or bridges, is based on
several factors: labor force, light production units, heavy production  units,
oil  units,  radioactive material units, available cash, and technology level.
The quantities or levels required vary with the object being built.

In order to build anything, the sector involved needs to have avail. Avail  is
work  available  in the sector after the demands of the update (building effi-
ciency, working on things, etc) Avail in the sector is show in the  output  of
the census command in the 'avail' column.

The  "Number to build" option may only be given if the command is being speci-
fied totally on the command line. If you give multiple sectors and a number to
build,  it will attempt to build that number at EACH sector specified.  If you
ask to build more than 20 units, it will ask you "are you  sure  you  want  to
build so many?".

If  you  don't  specify  TECH then it will build the unit at your current tech
level.

BUILDING BRIDGES

If you type
   [##:##] Command: build b 1,3
and 1,3 has enough hcm (heavy construction materials), the  workforce  in  the
sector  is  large  enough  (as defined above), you have enough money, and your
technology level is high enough, then the program will respond:

   Bridge head at 1,3
    + k
   o a .
    . .
   build span in what direction? n

With the EASY_BRIDGES option enabled, bridges may be  built  from  any  sector
that  is  at  least  60% efficient.  Otherwise, bridges may only be built from
bridge-head sectors.  The sector the bridge span is to be  built  in  must  be
adjacent to at least 1 non-sea, non-bridge span sector.

If everything is correct, you get:

   Bridge span built over 2,4

To  find  out  the required amounts of materials, workforce, and money use the
show bridge build command.

You may now also build bridges all in one line as in:
   [##:##] Command: build b 1,3 n

A sector that has a bridge built in it is automatically cleared  of  mines  at
the time of building.

Bridge  spans  are  built  at  20%.  If the efficiency drops below 20% (due to
bombing, shelling, etc.) the bridge span falls.

If a bridge falls, all mines in the sector are likewise cleared.

BUILDING BRIDGE TOWERS

If you type
   [##:##] Command: build t 1,3
and 1,3 has enough hcm (heavy construction materials), the  workforce  in  the
sector  is  large  enough  (as defined above), you have enough money, and your
technology level is high enough, and the sector is a  bridge  span,  then  the
program will respond:

   Building from 1,3
    + a
   o = .
    . .
   build tower in what direction? n

Bridge towers can only be built if the BRIDGETOWERS option is enabled.

In  addition, bridge towers can only be built in open water, i.e. not adjacent
to any land or other bridge towers.  Bridge towers must be built  from  bridge
spans that are at least 60% efficient.

If everything is correct, you get:

   Bridge tower built in 2,4

To  find  out  the required amounts of materials, workforce, and money use the
show tower build command.

You may now also build bridge towers all in one line as in:
   [##:##] Command: build t 1,3 n

A sector that has a bridge tower built in it is automatically cleared of mines
at the time of building.

Once a bridge tower is built, you may build other bridge spans from it.

Note  that  you  cannot navigate through a bridge tower like you can through a
bridge span.

Bridge towers are built at 20%.  If the efficiency drops  below  20%  (due  to
bombing, shelling, etc.) the bridge tower falls.

If  a  bridge  tower  falls, all mines in the sector are likewise cleared.  In
addition, if a bridge tower falls, all bridges  around  it  are  knocked  down
unless  they have another supporting bridgehead (such as another tower, bridge
head or next to land if EASY_BRIDGES is on.)

NUCLEAR PLANT SECTORS & BUILDING NUKES

If you type
   [##:##] Command: build 6,2
and 6,2 is a nuclear plant that has enough hcm (heavy construction materials),
lcm  (light  construction materials), oil, and radioactive material, the work-
force in the sector is large enough (as defined above), you have enough money,
and  your  technology  level is high enough, then the program will construct a
new nuclear device of the type requested, and add it to the current  stockpile
in that sector.

Note:  If  the  DRNUKE  option  is  enabled, you will need a certain amount of
research to make nukes. At the present time, it is  1/3  the  amount  of  tech
needed to make the nuke. See the show command, which lists this if applicable.

TYPES OF THINGS YOU CAN BUILD (besides bridges)

Many different types of units/ships/planes/nukes are available.  For  a  brief
table  indicating the production costs of the different things, respond with ?
when asked for the type, or use the show command.  Note that if there are  two
things  in  the  list  of  items  that  are similar, such as "destroyer 1" and
"destroyer 2", you will need to give the full name, or the program will  build
the first one that it encounters.

Note:  if  you wish to give the ship-type argument on the command line, it may
be necessary to quote the ship-type. For example: build s 0,0  "lander  2"  80
would build a lander 2. Without the quotes, it might build a lander 1 instead,
since the ship-type is two words.

Once built, units/ships/planes grow in efficiency until they reach 100%.  This
growth  is  accomplished using the avail left in the sector at the time of the
update, so if you use all the avail building things, there won't be  any  left
to  make them more efficient. The avail there is divided amongst all things in
the sector needing work, so the more units/ships/planes there, the  less  each
will  be worked upon.  Ships/planes/units also require materials be present in
the sector to gain efficiency. In general, for  each  1%  the  ship/plane/unit
gains in efficiency, it will use 1% of the materials listed by show.

HEADQUARTERS SECTORS & BUILDING LAND UNITS

Land  units  are  built in headquarters sectors. (designation !).  In order to
build a land unit, you must have 10% of the items listed  by  show  (typically
military,  lcms,  hcms,  guns,  shells,  petrol, etc) available at the time of
building. The land unit will appear at 10% efficiency (a unit of less than 10%
efficiency  is dead). Then, each update, the unit will grow in efficiency, and
use up more of the required goods until it reaches 100%.  Land units can  also
gain efficiency in fortress sectors, but cannot be built there.

The work required to add a point of efficiency to a land unit is

   (20 + (lcm_to_build + 2 * hcm_to_build))/100

A  land  unit  will can gain efficiency in any other sector type (assuming the
correct goods are available), but at 1/3rd the normal rate.

HARBORS & BUILDING SHIPS

Ships are built in harbor sectors. 20% of the materials listed by show must be
available at the time of building.  (typically hcms & lcms) Ships first appear
at 20% efficiency and a 19% efficient ship will not float  (i.e.,  it  sinks).
Then,  each  update,  the ship will grow in efficiency, and use up more of the
required materials until it reaches 100%.

In addition to the avail in the harbor sector, ships are  also  worked  on  by
their  crews.  So, for fastest efficiency growth, put full crews on your newly
built ships and leave them in harbor until they reach 100%.

The work required to add a point of efficiency to a ship is

   (20 + (lcm_to_build + 2 * hcm_to_build))/100

Ships at sea have only their crews to make repairs.  Crew members each  supply
the  same amount of work, whether civilian, military, or uncompensated worker.
A small crew on a large ship may not be able  to  make  any  repairs  at  all.
(Moral:  keep  your  ships  fully  crewed  in  anticipation of future damage.)
Repairs at sea do not use any lcms or hcms, but may not push the efficiency of
a ship over 80%.

Entropy  acts  on  ships without sufficient crews. In general, if a ship is at
sea, and has less than about 40% of its maximum crew, it will gradually  rust,
take on water, and sink.

        The amount of efficiency lost depends on the ship size and crew level.

        Figure the following quantities:

        Avail is the work done by the crew:

             On a military ship: work = etus * mil/2
             On a civilian ship: work = etus * (civ/2 + mil/5)

        Crew is the current # of mil (for a military ship), or civs for a
   civilian ship.

        Max crew is the max # of mil/civs (depending on ship type)

        W_p_eff is the amount of work per point of efficiency of the ship:

             w_p_eff = 20 + (lcm + 2 * hcm);

        Lcms & hcms are the cms required to build the ship.

        Then,  subtract (etus * (100-((crew*100)/max_crew)))/7 from the avail.

        If the result is less than 0, divide it by the w_p_eff, and subtract
        that amount from the ship's efficiency.

        avail -= (etus * (100-((amt*100)/abs_max)))/7;
        ship->shp_effic += avail/w_p_eff;
        Example: A frigate (a military ship) can hold 60 mil. It has only 10.

        w_p_eff = 20 + (lcm + 2*hcm) = 20 + (30 + 2*30) = 110
        Avail = etus * mil/2 = 60 * (10/2) = 300

        300 - (60 * (100-((10*100)/(60)))/7) ~= -420

        Since the result is negative, divide it by w_p_eff:

        420/110 = 3.8 = 4% loss of efficiency

        Note from this that the frigate would need 24 crew to break even.

AIRPORT SECTORS & BUILDING PLANES

The  choices  range  from low tech fighter 1 planes up to and including super-
long range jet hvy bombers and icbms.  For a brief table indicating  the  pro-
duction  costs  of  the different plane types respond with ?, or check out the
show command.

Note  that  planes  first  appear  at  10%  efficiency.   10%  of  the  listed
hcms/lcms/crew  must be in the airport in order to build the plane. (typically
hcms, lcms, and mil (crew)) In order for the  plane  to  gain  efficiency,  it
needs  hcms/lcms/mil, as ships and land units do.  As time passes, and as long
as there are available work units in the airport at which  the  planes  reside
(to work on the planes), they grow to 100% efficiency.  A plane is not capable
of leaving the ground until it has reached 40% efficiency.

The work required to add a point of efficiency to a plane is

   (20 + (lcm_to_build + 2 * hcm_to_build))/100

Planes will also gain efficiency in non-airport sectors, but at only 1/3rd the
normal rate.

If the CARRIER_WORK option is enabled, planes on carriers will also gain effi-
ciency. The amount of work available is based on the carrier's crew,  and  the
rate  is  the  same  as  a  non-airport sector.  Repairs at sea do not use any
lcms/hcms/mil, but may not push the efficiency of a plane over 80%.

Once you have reached tech level 290, you  are  no  longer  allowed  to  build
planes that have tech level below 151.

NAME
   buy - Purchase commodities from the world market

Level: Expert

SYNTAX
   [##:##]% buy    

The  buy  command  allows  nations to purchase commodities on the open market.
Not all commodities can be traded -- notably civilians and military.

It is based on a bidding system, and after the bidding time  has  passed,  the
transactions  are executed, and the highest bidder gets the goods (maybe.)  If
there are no bidders once the time passes, the goods stay on  the  market  and
the first bidder will get them.

Typical output looks like:

NAME
   capital - Change the location of your capital

Level: Basic

SYNTAX
   [##:##]% capital 

This  command  changes  the location of your nation's capital.  The new sector
must be of type "capital" or "mountain", and must be owned by you.  Your capi-
tal produces BTUs.  See "info BTU" for the exact rate of BTU production.

This command does not change your coordinate origin (where 0,0 is located), so
if you prefer your coordinates centered on your nation's capital, you must use
the origin command.  For example:
   [##:##] Command: capit -10,-4

   Your capital is now at -10,-4.

   [##:##] Command: orig -10,-4

   Designation of new origin requires revision of sector numbers.
   Origin at -10,-4 (old system) is now at 0,0 (new system).

If  the  unthinkable  should come to pass, and an enemy captures your capital,
bad things happen. Some happen once, immediately:

   1) You will lose half your cash, or $3K, whichever is more.
   2) Your enemy will gain half your cash times (1/5 + 4/5 * sector efficiency)

Re-taking a previously taken capital has no further effect. Once a new capital
has been declared with this command, you are again in peril of these two awful
things.

Some effects happen right away, and last until you use the capital command  to
create a new capital. The effects are:

   3) You will not be able to use many commands (use the
      'list of commands' command to see the pitiful few you may still use)

   4) The rate at which you gain BTUs will dramatically decrease (see
      info BTU).

NAME
   cede - Give a ship or sector to a friend

Level: Expert

SYNTAX
   [##:##]% cede   [se|sh]

This  command  gives  a  sector or sectors to the country of your choice, or a
ship or ships.  A sector to be ceded must have mobility, and must be  adjacent
to  a sector with mobility owned by the country you are cedeing it to, OR con-
tain a ship owned by the country you are cedeing it to, OR a sector  owned  by
the recipient that contains a land unit with mobility.

A  ship to be ceded must either be in a sector owned by the recipient, or in a
sector containing a ship owned by the recipient.

You may only cede to nations which consider you a friendly trading partner.

All contents of the sector become the property of the new owner, such as  com-
modities, planes, land units, etc. Ships, however, do NOT change ownership.

All  contents  of a ceded ship become the property of the new owner, including
planes or land units. Distribution & delivery info of ceded sectors are wiped.

The  ceded sector has its mobility set to zero. If the owner of the sector was
not the old owner when he ceded it, the old owner is not changed.  The  mobil-
ity of a ceded ship is not changed.

If  it  is ambiguous whether you wish to cede a sector or a ship, then you can
specify a third argument of either sh or se meaning ship  and  sector  respec-
tively.

NAME
   census - Report contents of sectors

Level: Basic

SYNTAX
   [##:##]% census 

The census command displays specific information on some or all of the sectors
you occupy.

In the syntax of the census command  is the  area  on  which  you  wish
information, (see info Syntax).

A typical usage might be:
   [##:##] Command: census 0:9,0:9 ?des=m
which would list data for mines in an area to the south-east of the capital.

A census lists each of your sectors in the specified area headed by:

   Tue Oct 10 22:24:49 1995
   CENSUS                   del dst
     sect        eff prd mob uf uf *  civ  mil   uw food work avail ter coast

These columns represent:

sect  the x and y coordinates of the sector
 eff  the  efficiency of the sector (affects all benefits of a designated sec-
      tor except mobility units)
 prd  Will this sector be updated? If not, you will see an 'n'.  This  can  be
      controlled with the start and stopcommands.
 mob  the number of mobility units, (see move)
  uf  Two delivery columns corresponding to: uncompensated workers and food.
  uf  Two distribute columns corresponding to: uncompensated workers and food.
   *  occupied enemy sector.
 civ  the number of civilians
 mil  the number of military troops
  uw  the number of uncompensated workers
food  the amount of food
work  the percentage of civilians working in the sector (based  on  the  local
      sector happiness).
avail  the  quantity of workforce available for construction or maintenance of
      planes, ships, or nukes.
 ter  This is a territory for the sector that you can specify using the terri-
      tory command.
coast  Is  this  a  coastal sector?  Note that the "coastal flag" gets set for
      the sector only when you use the census command, so if you want to query
      your  sectors depending on whether they're coastal, then you may need to
      do a census twice--the first time to set the coastal flags, and the sec-
      ond time to query them.

For example:

name associated with your country.

COUNTRY NAME

   [##:##] Command: change country Hodedo
This will change the name of your country to Hodedo.  In order to change  your

NAME
   coastwatch - Check from sectors for nearby ships

Level: Basic

SYNTAX
   [##:##]% coastwatch []

The coastwatch command allows coastal sectors to report sightings of ships.

Visibility  range  is equal to four times the sector efficiency expressed as a
decimal times the technology factor; e.g. a 100% efficient harbor with  a  50%
technology  factor  can  see  2 sectors away.  An exception is radar installa-
tions, which have a maximum range equal to fourteen  times  the  sector  effi-
ciency, (i.e. 3.5 times as far).

A typical usage might be:
   [##:##] Command: coast #3 ?type=)

     3,-11 efficiency 100%, range 5.6
   Pandora (#5) oil derrick #74 @3, -9
    -1,4   efficiency 100%, range 5.6

NAME
   collect - Foreclose an overdue loan

Level: Expert

SYNTAX
   [##:##]% collect 

The  collect command is the loan-shark's delight!  Through the collect command
overdue loans can be cleared up.

If you should find that you have a problem debtor who refuses  to  pay  up  on
your  kind  loan you can always seize one or more of his/her sectors.  Perhaps
the mere threat of a collection on someone's capital may do the trick!

To settle up accounts on overdue loan #9 you would type:
   [##:##] Command: collect 9
The program would then ask which sector you would like to claim  as  just  and
rightful compensation for the outstanding debt.

   What sector do you wish to confiscate?

To  which  you  reply with the coordinates of a sector owned by your debtor to
which you are adjacent.  Any adjacent sector includes any sector you have that
borders the sector you wish to confiscate.

The program then paws over the sector and assesses its value:

   That sector (and its contents) is valued at $2345.00

If  the  amount you are owed exceeds this amount the sector becomes yours!  If
the value of the sector is close enough to the amount you are owed the debt is
considered to be repaid.

Any  che  in  the  area are left alone.  Thus, if the original owner takes the
sector back over, the che would continue their  battle  against  the  original
owner, not the new owner.

In  addition,  ships,  land  units, planes and nuclear stockpiles are not col-
lected.  Those remain the property of the owner of the sector.

Standing military in the sector are reduced to 1 and he becomes the latest and
greatest addition to your standing army.

Mobility of the collected sector remains unchanged.

Level: Expert

SYNTAX
   [##:##]% consider loan  accept|decline|postpone

SYNTAX
   [##:##]% consider treaty  accept|decline|postpone

This  command  allows  you  to  consider accepting a loan or treaty offered by
another country.

The program will list the various terms of the loan or treaty under considera-
tion  and  ask  for  your  decision as to whether to accept the terms, decline
them, or postpone making a decision.

If you accept a loan, the money is immediately credited to  your  account  and
the  time  period  of the loan starts.  If at the time of your acceptance, the
lender does not have sufficient funds the size of the loan will be  diminished
to fit the lender's cash on hand.

If you accept a treaty, it goes into effect immediately but the time period of
the treaty is calculated based on the offer date rather  than  the  acceptance
date.

Loan offers are withdrawn if not accepted within a number of days equal to the
proposed loan's duration.

Treaty offers expire at the time the proposed treaty would expire.

Warning: When the terms of a loan are printed out, take note of the due  date;
if  you  do  not  pay by the due date the interest will double and you will be
subject to collection, (see info collect).

NAME
   convert - Change conquered civilians into uncompensated workers

Level: Basic

SYNTAX
   [##:##]% convert  

The  convert  command  converts  enemy  (captured) populace into uncompensated
workers.  If the sector is not actually conquered, no civilians will  be  con-
verted.  If you convert all the civs in a sector, then the sector is no longer
occupied (i.e. you become the "oldowner" of the sector).

After the program has collected any necessary information it  will  list  each
sector where civilians are converted.

Note:  you  must  have enough military in the sectors to force the populace to
become uncompensated workers -- about 10%. Land units count toward this  at  a
value  equal  to  the number of mil required to build them. Security units are
even more efficient, counting for more than their base value, and increase the
number converted.

There  must  also be mobility in the sector to be converted (see info Mobility
for the exact formula).

   [##:##] Command: conv -3:3,-1:2 10

 may be alliance, friendly, neutrality, hostile, or war;

For a complete list of the meanings of all the different types  of  relations,
see "info relations".

GOING TO WAR

(Note:  the  following  stuff  is  only  in  effect  if the SLOW_WAR option is
selected) With the SLOW_WAR option in use, you cannot attack the land of some-
one  you  are  not at war with. When you declare war on someone, your relation
goes to mobilizing. You still can't attack them.  After the next update,  your
relation  goes  to  sitzkrieg, and you still can't attack them. After the NEXT
update, you're at war with them, and anything goes.

If someone is mobilizing or in sitzkrieg, or at war with you, and you  declare
war  against  them, your relation is set to be the same as theirs, so there is
no way to gain any advantage through this stuff. It just means that you  can't
sneak-attack people.

The first person who declares war pays $1000. Return declarations are free.

There  is  an exception to the SLOW_WAR restrictions. If you are listed as the
old owner of a sector, you are still allowed to attack it. This is to  prevent
someone  from declaring war with you, taking some sectors, then declaring neu-
trality before you declare war. (Assuming you didn't notice their  declaration
of war)

Also,  if  the  SNEAK_ATTACK  option is enabled, you make make one attack upon
someone you're not at war with. You'll pay $5K  for  the  privilege,  however.
Once  the  sneak  attack  is over (win or lose), war is automatically declare.
(The normal $1K cost is waived in this case)

The newspaper is very interested in declarations of war or alliance  --  don't
expect to keep such declarations secret.

Deities  can  will  be prompted for a third parameter, the country to make the
declaration for. The default is to make it for the deity's country.

NAME
   deliver - Establish delivery routes for shells, ore, etc

Level: Expert

SYNTAX
   [##:##]% deliver   [q|] []

An  example of using deliver in addition to distribute is where you may have a
mine which uses distribute to get its food from a warehouse, but uses  deliver
to export its iron to the adjacent hcm factory.

Deliver  may  be  used  to  extra-fine  tune a distribution network.  In fact,
deliver can greatly improve the performance of a distribution network if  used
properly.

If  'q' is specified rather than a threshold, then the delivery directions and
thresholds will simply be listed.  You can also use the  "cutoff"  command  to
list delivery thresholds.

The  number  specifies how much of that commodity you would like to be
kept in the sector.  If you do not want to change the direction that a  sector
delivers to, then put a '+' before the number .

Note  that delivery thresholds are stored as multiples of 8.  If you specify a
threshold that is not a multiple of 8, it will be rounded down.

The direction must be specified as one of the six direction characters,  (usu-
ally  `y'  `u' `j' `n' `b' or `g'), the no-direction character, (usually `h').
If no direction is specified, then the direction will not be changed for  that
sector.

   [##:##] Command: deli f 0,0 0 j
Will deliver all food from 0,0 to 2,0.
   [##:##] Command: deli i * ?des=m +87
Will set iron delivery threshold to 80 in all mines.
   [##:##] Command: deli l * q
Will  list all lcm delivery specifications.  (Sectors with no delivery thresh-
old or direction will not be listed).

The census and commodity reports will indicate deliveries by the same  charac-
ters used to specify them in this command.

If,  during an update, the destination sector is not owned by you, the message
delivery walkout between x,y & x,y will be printed and nothing will be  deliv-
ered.

Delivery routes may also be mapped out with the route command.

See "info Mobility" for an explanation of mobility costs.

NAME
   demobilize - Change military into civilians

Level: Basic

SYNTAX
   [##:##]% demobilize  

The  demob  command  returns soldiers from the military back to civilian life.
In addition, you have the option  of  placing  the  returning  GI's  into  the
nation's active reserve.  The active reserve provides a pool of available mil-
itary for a small salary (usually the same amount generated by a civilian) and
provides  for quick mobilization of military during a threat to national secu-
rity.

As a result of demobilization, and as a thank you for serving their country in
its time of need, a GI Bill is given to each soldier to the tune of $5 each.

Troops  can  only  be demobilized in sectors which have greater than 60% effi-
ciency, and only in home sectors (that is, not in occupied territory).

When troops are successfully demobilized in a given sector, the number of  new
civilians  is printed, and the number in parentheses shows the total number of
military left in that sector.

You have the option of placing civilians  on  active  reserve.   Civilians  on
active reserve can later be enlisted but you must pay them to stay on.  Gener-
ally civilian on active reserve costs one tenth of what a military costs.

   [##:##] Command: demob -2:0,0 1

   New civilians on active reserve? (y/n) y
   1 demobilized in -2,0 (19 mil left)
   1 demobilized in 0,0 (9 mil left)

NAME
   designate - Specify sector utilization

Level: Basic

SYNTAX
   [##:##]% designate  

In  Empire  all  sectors  have  a designation.  The designation represents the
principal industry or activity taking place in that area.  When  a  sector  is
designated  a  harbor, for example, the civilians in the sector start building
shipyards and docks, (with a little help from any military present).

If the redesignated sector is already declared to be something  else,  and  is
efficient,  then  the workers will have to tear down the existing construction
and then build the new sector.  The workers dismantle  existing  sectors  four
times faster than they can build.

As work progresses the efficiency will climb toward a maximum of 100%.

If you don't specify the  argument in the command line as in:
   [##:##] Command: designate 1:3,2:5
The  program  will  ask for each sector specified what you want the new sector
designation to be.

However, if you wish to designate one or several sectors to be one  particular
thing and don't want to be asked on each one you can type something like:
   [##:##] Command: designate -6:6,-3:3 ?type=f +
This  will  designate all fortresses that you own within three sectors of your
capital to be highways.

Note that you cannot re-designate bridge spans.

Normally, each point of efficiency added costs you $1. Some sectors  may  cost
more,  and  some may also require the expenditure of lcms and/or hcms from the
sector. In addition, some sectors may cost money merely to designate. (see the
show command and info show for details)

NAME
   distribute - Establish distribution destination sector

Level: Basic

SYNTAX
   [##:##]% distribute  

The  distribute command is used to specify the way that goods will travel dur-
ing an update.  Each sector is allowed to have one and only  one  distribution
sector  (a warehouse or road, typically).  Subsequent distribute commands will
replace the existing distribution sector.

For example,
   [##:##] Command: distribute 2,0 8,4

   highway at 2,0 delivers to 8,4.
   Distribution sector? 7,-1
   highway 2,0 new path distributes to 7,-1 (cost 0.200)
           Current best path is 'gguh'

This command changed the distribution path for sector 2,0 from a warehouse  at
8,4  to  a  warehouse at 7,-1. The cost is the mobility cost to move 1 normal-
weight unit from the sector to the warehouse.

DISTSECT is a normal empire sector specification. During  the  update,  empire
will  determine the cheapest existing path to the distribution sector, and use
that. (Note that the mobility cost for the path used during the  update  could
be  different  than  the cost reported to you when you use the distribute com-
mand, if you have re-designated sectors, or sectors were captured, etc) Again,
it will use the cheapest path available AT THE TIME OF THE UPDATE.

You may also use '.' or 'h' to specify no distribution sector.

   [##:##] Command: dist 2,0 .

   Distribution to and from 2,0 halted.

The  command  will  warn  you if there is no existing path completely owned by
you, and also if the path does not end at a warehouse.   It  is  not  required
that the distribution path end at a warehouse, but it is required that you own
all the sectors that the goods will travel along.

Distribution & the Update

One of the last things that takes place during the update, after  all  growth,
production,  delivery,  etc,  distribution  takes  place. (The only thing that
really happens after that is mobility increases) Each sector may have  product
thresholds and a distribution sector. A threshold is a target level for a par-
ticular commodity, like food. So, if the food threshold for a sector  is  100,
it  will try to maintain 100 food there. If it has more than 100 food, it will
export it to its distribution point. If it has less than 100, it will  try  to
import food from the distribution point to reach 100.

During the distribution phase of the update, all sectors (going left to right,
top to bottom) first export excess commodities, and then (again left to right,
top to bottom) import needed commodities.

In  order  to  either send things to or get things from a distribution sector,
you must own the distribution sector, and there must be a path of  owned  sec-
tors to it. In order to export something from a sector, you must have military
control of the sector. In order to import something from a  distribution  sec-
tor, you must have military control of the distribution sector. (Military con-
trol is defined as having mil in the sector equal to at least 1/10th the  num-
ber  of unconverted civilians there. Units count as if they were straight mil,
i.e. a 100% unit that contained 50 mil would count as 50 mil for the  purposes
of control)

Mobility  is  used  from  the  sector when sending to the distribution sector.
When getting something from the distribution sector, mobility is paid  by  the
distribution  sector.  See info Mobility for an explanation of mobility costs.

Amount

The amount is determined by  the  threshold,  as  explained  above.   Use  the
threshold command to specify what goods will flow to and from the warehouse.

Finding sectors with not dist point set

If  you want to find sectors with no distribution point set, use the xdist and
ydist selectors:

   [##:##] Command: level # ?xdist=xloc&ydist=yloc

This finds all sectors that have themselves as a distribution point.

Distributing civilians

When distributing civilians, no distribution point  will  ship  out  its  last
civilian,  regardless  of thresholds set in sectors using it as a distribution
point.

Route  is  a normal empire path specification. You may also give a destination
sector on the command line, or at any time while giving the route, and  empire
will use the best path from the current sector to the desired destination sec-
tor.

When getting a path interactively, empire will show you  the  information  you
have  (from  your  bmap)  concerning  the  current area, to help you plot your
course.

Planes which arrive safely at the target sector will drop the goodies  off  to
the waiting people below.

Any  plane with the mine ability can mine a sector by dropping shells in a sea

Level: Basic

SYNTAX
   [##:##]% enlist  

The  enlist command converts civilians into military in the sectors specified.
Military created by the enlist command are actually reserves  called  up  from
your  country's  military  reserve.   If your country has no military reserves
(created by demobilize) then no civilians will be converted  and  no  military
will be generated.

After  the  program has collected any necessary information, it will list each
sector where civilians answer the call and the number who showed  up  followed
by the total number of military resulting (in parentheses).

If    is  a  positive number that many draftees will be sought in each
sector regardless of any military already in the sector.

If  is a negative number of the form -xxxxxx, then an enlistment quota is
established  and  the draft board will attempt to enlist enough in each sector
to bring the total number of military up to xxxxxx in each sector.

Although the program tries to draft the specified number of civilians in  each
sector  only  one-half  of the civilians in a sector can be called upon at any
one time.

Civilians in conquered sectors (the conquered populace) will not serve in your
armed forces.

NAME
   explore - Claim unowned land

Level: Basic

SYNTAX
   [##:##]% explore    

The  explore command takes over part of the functionality of move.  Explore is
used to stake your claim to unowned sectors.  Only civilians and military  can
be used to explore.

 can be any one of:

   c       civilians
   m       military

If    is  not provided in the command line, the program will request the
starting sector then display the resources of that sector and  a  map  of  the
adjoining  sectors.   The  prompt  consists of the number of mobility units in
that sector, its designation, and its coordinates in the form:

   <97.0: a -6,4>

which indicates 97 mobility  units  in  agribusiness  sector  -6,4.   You  may
respond with any combination of:

   y  for up-left
   u  for up-right               y    u
   g  for left                    \\  /
   j  for right               g  --  --  j
   b  for down-left               /  \\
   n  for down-right             b    n
   v  for view
   m  for map
   h  for end of movement

The  view  command shows the sector efficiency and some of the contents of the
sector you are currently occupying.

Since the  can be specified in the command line, simple  movements  are
often typed as a single line, such as:
   [##:##] Command: explore m 2,0 20 jjjh
Or  some  movements may be done partly on the command line and partly interac-
tively:
   [##:##] Command: explore c 2,0 1 gg

       - ^         min gold fert  oil uran
      - - +         67    0    0    0   82
       - ^

      - - +         67    0    0    0   82
       - ^
   <125.4: - -4,0> h
   Sector -4,0 is now yours.

You may also simply specify the destination sector on  the  command  line.  In
this  case,  empire  will  set  the  path to be the cheapest path (in terms of
mobility) from the current sector to the destination sector, if  such  a  path
exists. However, the best path cannot extend out of your owned sectors, so the
best use for this feature is to use it to get to the edge of your owned terri-
tory, and then explore manually from there.

For example,
   [##:##] Command: explore 2,0 1 -2,0

       ^ -         min gold fert  oil uran
      - + c         67    0    0    0   82
       ^ -
   <126.2: - -2,0> g
       - ^         min gold fert  oil uran
      - - +         67    0    0    0   82
       - ^
   <125.4: - -4,0> h
   Sector -4,0 is now yours.

See 'info Mobility' for a description of how much mobility it costs to explore
into sectors.

Note that while exploring, you might hit mines.  The  more  civs  or  mil  you
explore  with,  the greater the chance of setting off any mines in the sectors
you move through. See info lmine for details.

The  financial report shows all of the outstanding loans in the world, so that
the loan sharks can better calculate the ability of a  prospective  client  to
pay.

It  does  not  show  loan offers pending, however, just those loans which have
been accepted.

If a loan is past due (i.e. the loanee has defaulted on  the  loan)  the  "(in
arreras)"  is  printed  after  the line of that loan.  Loans in default may be
"sharked" up and collected upon.

NAME
   fire - Fire artillery from sector/ship/unit on sector/ship

Level: Basic

SYNTAX
   [##:##]% fire [sect | ship | land] [ |  | ] [ |
]

When the multi-fire option is enabled, the syntax of the fire command changes.
It  is  still used to shoot up land sectors or ships. However, you may now use
multiple ships, units, sectors to fire from. Return fire is spread amongst all
the firing things.

If  the  SLOW_WAR  option is in use, you cannot fire on the land of any nation
you are not at war with. (see info relations)

The general form for shooting at land from a sector is:
   [##:##] Command: fire sect  
Where  is the victim sector, (the sector AT which you are shooting, not
the sector FROM which you are shooting).  ASECTS is a sector or sectors.

The general form for shooting at land from ships is:
   [##:##] Command: fire ship  

The general form for shooting at land from units is:
   [##:##] Command: fire land  

The general form for firing at ships from land is:
   [##:##] Command: fire sect  
Again,  is the victim ship number.

The general form for firing at ships from ships is:
   [##:##] Command: fire ship  

The general form for firing at ships from units is:
   [##:##] Command: fire land  

If  not  specified on the command line the program will ask for the sector(s),
land unit(s), or ship(s) FROM which you are firing,  (,  ,  or
).  It will also prompt you for targets for each sector/unit/ship fir-
ing, if you did not specify the target on the command line.

The only sector that may fire is a fortress, which must be at least  5%  effi-
cient,  have  at  least  two military for a firing crew, at least one shell to
fire, and a gun big enough to reach the victim location; range is equal to  (7
* ((tech+50)/(tech+200)). If the fortress is at least 60% efficient, it gets a
+1 range bonus.  A fortress firing uses 1 shell.

Note that forts cannot fire if the NO_FORT_FIRE option is enabled.   See  info
Options for more info.

Any  military ship may fire as long as it has at least one crew (which must be
military, not civilians), at least one gun, at  least  one  shell  (or  shells
within  supply range), and has at least 60% efficiency.  A ship's gun range is
its firing range,  as  shown  by the  show  command,  divided  by  two,  times
((tech+50)/(tech+200).  A ship uses one shell per two guns firing.

Any  land  unit may fire as long as it has at least one military, at least one
shell (or shells within supply range), and has at  least  40%  efficiency.   A
land  unit's  gun  range  is  its  firing range, as shown by the show command,
divided by two, times ((50+tech)/(200+tech)).  A land unit uses the amount  of
ammo,  as  shown  by  the lstat command, each time it fires.  A unit with less
shells than its ammo requirement will do proportionately  less  damage.   (See
show for firing ranges)

Forts, land units, and non-depth-charge-equipped ships
 cannot  hit submarines on the high seas.  The only way to fire on a submarine
is to have a depth-charge-equipped ship drop a depth charge on it, costing two
shells.   (Note you can also hit subs using ASW planes or subs which have sub-
torp capability.)

The program then prints a satisfying  Kaboom!!!  and,  assuming  you  were  in
range, inflicts damage.

Ships lose mobility points equal to 1/2 the cost they would pay to move 1 sec-
tor for each shot fired. (If the NOMOBCOST option is  in  use,  ships  pay  no
mobility for firing.)

The  damages  inflicted  vary with efficiency of the attacker, the size of the
guns (battleship guns are four times as big as patrol boat guns),  the  number
of guns fired (7 being the useful max for forts), and the armor of the victim.
Land sectors take damage depending on their defensive strength.  Use the  com-
mand  'show  sector stats' to show defensive strengths.  The higher the defen-
sive strength, the less damage the sector will take.

An illustrative example of shelling land:
   [##:##] Command: fir sect 36,18 34,18

   Kaboom!!!
   13% damage done to sector 34,18

Meanwhile, the owner of sector 34,18 might be logged on and would perhaps  see
the following:

   [15:98] Command: cen 34,18

        1 sector

Note that the shell did about 13% damage in the sector.

The player could have typed:
   [##:##] Command: fir sect #0 ?des=f 34,18

In that case, ALL forts in realm 0 would have fired on sector 34,18.

If  the  sector fired on is a fort with guns and shells it will fire back with
approximately the same damages (assuming it has the range).

Also, any friendly forts, units, or ships within range of  the  attacker  will
return  fire,  including  those  belonging to allies, if the allies are at war
with the attacker as well.

If a ship fired on has guns and shells it will fire back AND any other  ships,
units,  or  forts  of the same nationality that are in range will also fire on
you.

All return fire is split evenly over all attacking sectors/units/ships, and is
adjust by the ratio of defending things to attacking things.

As  a change from the original fire command, with multi-fire enabled, you will
not return fire on yourself.

IMPORTANT NOTE: Gun ranges, both on offense AND defense, are somewhat  random.
If  you have a range of 4.16, you can always shoot to 4, and have a 16% chance
of being able to fire at range 5...

NAME
   flash - Send a message directly to a friend's terminal

Level: Expert

SYNTAX
   [##:##]% flash  []

The    argument  is  either  the  number  or name of the recipient
nation.

flash allows instant communication between friendly nations.   flash  has  two
different syntaxes.  You can either send your friend a one line message as in:
   [##:##] Command: flash Foobots Hi there, I'm back from lunch

Or you can send a multi-line message:
   [##:##] Command: flash Foobots

   > Hi there.
   > I ate Fodderland for lunch.
   > .

Note that you can end a multi-line flash with either a '.' (period) on a  line
all  by itself, or by hitting ^D on a line by itself.  Note also that all mes-
sages are truncated to 60 characters long!

If you do not wish to receive any flash messages from your friends,  then  you
can temporarily turn the feature off by typing "toggle flash".

Note  that  if  the  person  you  are  flashing  is allied to you, you will be
informed if they are not logged in or not accepting flashes when  you  attempt
to  flash  them.   This  only works when *they* are allied with you, since you
would normally see them logged in or not using "players"

NAME
   fleetadd - Designate members of a fleet

Level: Expert

SYNTAX
   [##:##]% fleetadd  

The fleetadd command is used to specify the fleet groupings of your ships.

   [##:##] Command: fleetadd  
In the syntax  is the alphabetic character to be used as the fleet des-
ignation.  This character can be chosen from the set of upper or lower case a-
z and tilde (~).  The pseudo-fleet specification tilde specifies all ships not
currently in any fleet.

The specification of ships, , can have one of several syntaxes:

   example     meaning
   -------     -------
   23          ship 23
   2/14/23     ships 2, 14, and 23
   c           all ships currently in fleet `c'
   ~           all ships currently in the null fleet
   2,3         all ships in sector 2,3
   -1:3,0:2    all ships in the square area bounded by -1,0 & 3,2

All fleets, (with the exception of the `~' fleet), are limited to some maximum
size and you will be informed how many ships can be added when this command is
run.

Having ships organized into fleets can be very  helpful  in  loading,  moving,
etc.,  in that fewer commands are required to perform these commands on groups
of ships if they can be specified by fleet number.

Note that you can remove ships from a fleet by adding them to the  `~'  fleet.
e.g.
   [##:##] Command: fleetadd ~ A
This command would purge all ships from fleet `A'.

NAME
   fly - Fly planes from sector/ship to sector/ship and bomb or snoop

Level: Basic

SYNTAX
   [##:##]% fly     

The  fly command is used to move planes and commodities from the starting sec-
tor(s), and ending up in the target sector.

 represents a list of planes which are to  travel  to  the  target
sector.  Only planes which are provided with gas, and have sufficient mobility
will be successfully selected for the mission.

 represent a list of fighter planes which are  capable  of  escorting
the  transports  all the way to the target.  To be selected, escorts must have
fuel and mobility.

 represents an assembly point, where all of the planes  in  the  mission
meet  before  proceeding  on to the target sector.  The assembly point must be
owned by you, and must not be more than four sectors  away  from  any  of  the
planes selected for the mission.

  is the name of a commodity which is to be carried along on all of
the planes which have a transport capacity.  If  nothing  is  specified,  then
nothing will be carried.

Route  is  a normal empire path specification. You may also give a destination
sector on the command line, or at any time while giving the route, and  empire
will use the best path from the current sector to the desired destination sec-
tor.

When getting a path interactively, empire will show you  the  information  you
have  (from  your  bmap)  concerning  the  current area, to help you plot your
course.

If the transports stray over enemy territory, then they  will  be  intercepted
and  shot at just like any other mission.  If the destination sector is not an
airport, then all planes in the mission must have VTOL capability.

Note that a plane must be at least 40%  efficient  before  it  can  leave  the
ground.

NAME
   follow - Cause one ship to automatically follow another

Level: Expert

SYNTAX
   [##:##]% follow 

You  use  the  follow  command  to  get a ship to use the same sailing path as
another ship.  At each update, ships with a sailing  path  autonavigate  along
the  path  that  was  set for them, and ships that are set to follow that ship
will also be navigated along the same path.  Telegrams notify you of  arrivals
or problems encountered while attempting to follow the path.

Radar  operates  continuously  as  the  ship  moves along the path, constantly
adding sector information to the known world map.

Ship movement is performed before mobility is increased.   This  insures  that
after  the  update, ships with a sailing path will still have some mobility so
that you can always manually navigate to some extent.

You may follow any ship which is owned by you or a friendly country.

NAME
   fortify - Fortify a land unit

Level: Basic

SYNTAX
   [##:##]% fortify  

The fortify command is used to make units dig in and make themselves harder to
damage. The maximum amount of fortification is the same as the maximum  amount
of mobility a unit can have. (The version command will print this info).  Each
point of mobility used increases the fortification value by one.

A fully fortified unit is twice as hard to hurt as it normally would  be,  and
is twice as strong on the defense.

Units  fortifying in a sector containing an engineering unit are better at it.
Experiment and find out.

If a unit moves or retreats, it loses all fortification value.   A  unit  that
reacts  to defend a sector, on the other hand, does NOT lose its fortification
unless it is forced to retreat. It receives the fortification bonus in combat,
and  is  still fortified when it returns to its original sector after the bat-
tle.

Note that fortification will not help a unit fight Guerrillas in  an  occupied
sector (see info Guerrilla).  Also note that fortifying a unit does not affect
it's mission status.

NAME
   fuel - Give fuel to a ship/unit

Level: Basic

SYNTAX
   [##:##]% fuel    []

The fuel command carries out the fueling of ships and units.  The ship(s) must
be in a harbor and the harbor must be at least 2% efficient.  Land  units  may
be in any sector.  Alternatively, you can fuel at sea using an oiler, which is
any ship with the oiler ability. (Note: if you are in a harbor, you can't fuel
from an oiler, you must use the harbor)

Ships  and units can be fueled by either petrol or oil, with petrol being used
first. 1 unit of petrol = 5 fuel units. 1 unit of oil = 50  fuel  units.  Each
ship  or  unit, in turn, will attempt to take on the specified amount of fuel.
Petrol/oil will be used for each ship or unit, the  amount  being  rounded  up
individually.  For  example,  if you have a harbor with 50 fuel in it, and you
tell a ship with a 50 fuel capacity to load 50 fuel, it'll use 1 oil.  If  you
tell  it to load *1* fuel 50 times, it'll use *50* oil, with the round-up mak-
ing it use 1 oil each time. The solution, of course, is to not  load  fuel  in
tiny, wasteful amounts.

Each  update,  ships and units use fuel to make mobility points. To produce 10
mobility points requires the number of units of fuel listed for  the  ship  or
unit  in  the  capability list. (see info show) (This number is usually 1, but
may be more). If the number is a 0, the unit does not use fuel.

If the ship or unit has no fuel, it will attempt to get fuel using the  supply
procedure  (see info supply). It will try to use first petrol, then oil, until
it has enough fuel to get full mobility.  If it can't get fuel  by  using  the
supply system, it won't get mobility.

See  show  for  a  table of the maximum amounts of fuel that can be carried on
each type of unit or ship.

You can fuel friendly ships, but must fuel them one at a time, by number.

If you include a number in the command, it will print headlines based  on  the
news from that many previous days.

The  headline  Relative  Calm  Prevails appears whenever the reporters haven't
been able to dig up any interesting tidbits to give the news analysts.

The headlines are produced by the editorial staff of the Empire News  who  are
solely responsible for their lack of content.

NAME
   improve - Improve the infrastructure of a sector

Level: Basic

SYNTAX
   [##:##]% improve   

The improve command allows you to improve the efficiency of the infrastructure
of your sectors.

The infrastructure of your sectors affects how well they defend, and how  easy
it is for you to move various commodities/vehicles (land units) thorough them.

To improve a sector, you need (most likely) lcms, hcms,  mobility  and  money.
See "info show" for the various costs.

Whenever you tear down a sector, the infrastructure is left in tact.  The only
way that infrastructure goes down is when the sector takes damage.

NAME
   launch - Launch missiles or satellites

Level: Expert

SYNTAX
   [##:##]% launch 

The  launch command is used to launch missiles (or satellites) from sectors or
submarines owned by you.

There are 5 classes of missiles:

   1. "marine" missiles may only be fired at ships.  They may be given
      "interdiction" mission.  When interdicting ships, "marine" missiles
      will keep launching until the entire enemy fleet is sunk.
   2. "tactical" missiles (without "marine" capability) may only be fired
      against sectors.  They may be given missions.  If they fire on a
      mission, then only enough missiles will fire to cause 100 damage.
   3. "intercept" missiles can not be launched.  They automatically
      intercept planes.  You can increase their reaction radius by giving
      them an "air" defense mission.
   4. "a-sat" missiles will automatically attempt to intercept AT_WAR
      satellites which are launched into orbit within range.
   5. "abm" (anti-ballistic-missiles) will automatically attempt to
      intercept incoming "tactical" (non-"marine") missiles.

   As well, there are "satellites" which are like missiles in that they
   can be launched, but unlike missiles in that they don't get destroyed
   as soon as they are launched.

In certain cases, a missile will require petrol or shells to be in the  sector
before  it  can be launched.  See 'show plane stats' to find out how much fuel
the missile requires.  The 'load' value in 'show plane  stats'  specifies  how
many  shells  the  missile requires.  Note that if the missile is armed with a
nucelar warhead, then it does not require any shells.

Once a satellite has been launched, it can not be moved again.

Note here that it is much safer to use 100% missiles than those which are less
efficient, and missiles below 60% cannot be launched.

The  formula  for  the  chance  that  a  missile  hits  its  target is in info
Hitchance.

Of course, things don't always go as planned!

Note that when you are first asked for the target sector you can  chicken  out
by hitting ^C (or your favorite abort character).

In  the  case  of non-marine tactical missiles, if there are any HOSTILE abm's
within range of the target sector, then two of them will fire in an attempt to
intercept the incoming missile.

Similarly,  two  AT_WAR  a-sat's  will attempt to intercept any satellites you
attempt to launch within their range.  Also, if the sector you  are  launching
your satellite at is owned by a non-allied country, then they will get a tele-
gram informing them of the  positioning  of  the  satellite.   See  below  for
details of a satellite's orbit path.

When launching missiles, there is a % chance equal to (5 + 100 - efficiency) *
(1 - techfactor) that the missile will blow up on the launching pad instead of
launching.  If  that happens, then there is a further 33% chance that the war-
head it is carrying (whether it be conventional  or  nuclear)  will  detonate.
(Note that nuclear warheads will only detonate in this way if the option NUKE-
FAILDETONATE is enabled).  A nuclear warhead exploding on the launch pad  will
do  the  normal amount of damage, but a conventional missile will only do half
damage to the sector or ship it is being launched from.

Missiles launched from submarines are anonymous. The victim is not notified of
the identity of the launching country.

Missiles  on  interdiction  mission have the same chance of hitting and do the
same damage as if they were launched by hand.  Also, any  nuclear  armed  mis-
siles  will  detonate  if they launch on an interdiction mission.  You specify
whether the nuclear warhead will airburst or groundburst when you arm the mis-
siles  (see  info arm).  In order to better destroy missiles on the ground (or
in their silos), the ground-burst technique is used.  Ground-bursts  are  much
less effective against large area targets, but do massive damage to the sector
it impacts, possibly knocking out hardened missiles before they  can  be  used
against  you.  In the parlance of nuclear targeting doctrine, this is known as
counter-force targeting.  Air-bursts are used in order to kill  large  numbers
of civilians, to knock out industry (by flattening the factories), to take out
lightly armored military targets in a  large  area,  and  to  generally  wreak
havoc.  Nuclear strategists call this a counter-value technique.

See Also On Thermonuclear War by Herman Kahn.

If  the ORBIT option is enabled, then when you launch a satellite, you will be
asked "Geostationary orbit?".  If you answer "y",  then  your  satellite  will
stay  where  you  launch it.  If, however, you answer "n", then your satellite
will orbit the planet.  When a satellite is "orbiting", it moves along 5% of a
geodesic path every update.  The path the satellite follows looks like this:

   +----+
   | /  |
   |/   |
   |   /|
   |  / |
   | /  |
   |/   |
   |   /|
   |  / |
   +----+

That is, start in the middle, move northeast until you hit the edge, then con-
tinue from the west edge near the top and go northeast until you  go  off  the
top  of  the map, then continue at the bottom going northeast until you go off
the eastern edge again, and continue from the western  edge  near  the  bottom
until  you  get  back to the centre.  That is the path of satellites which are
_not_ in geostationary orbit (geo-stationary means stay in the same spot  over
the planet).

If  a  foreign satellite moves over your territory durring an update, then you
will get a message like "Fodderland satellite spotted over 12,24" as a part of
your update BULLETIN.

The  load  command  carries out the loading of units.  Commodities (like guns,
civs, food) can be loaded onto any unit capable of carrying them (to see  what
cargos a unit can carry, use the show command).

Some land units can carry extra-light planes (typically these are SAM's)

Some land units can carry other units

SYNTAX
   [##:##]% lload   

In  the first form, the amount argument specifies the amount of the given com-
modity you wish to load on each unit specified.   Amounts  greater  than  that
allowed  will  be truncated to the maximum possible. Amounts less than 0 indi-
cate that you want to make the unit/army have that amount.  If  the  unit/army
has less than that amount, more will be loaded. If the unit/army has more than
that amount, the commodity will be unloaded. For example,

   [##:##] Command: load food 3 -100

will cause unit 3 to load or unload food so that it has 100.  If  it  had  120
food, 20 would be unloaded. If it had 50 food, 50 would be loaded.

SYNTAX
   [##:##]% lload plane  

In  the second form, where you say plane instead of say civ a plane/missile is
loaded onto a unit.

See the show command for a table of the maximum amounts of each items that can
be carried on each unit type.

Note  that if either  or  does not start with a number (e.g. it
is of the form "a" or "*" or "#1" and not of the form 123 or 12,14)  then  you
will  not be given any error messages.  This is so that you can type something
like "lload plane * *" without getting a hundred error messages.

NAME
   llookout - Check from units for other units, planes and/or sector types

Level: Basic

SYNTAX
   [##:##]% lookout 

The  lookout  command allows units to report sightings of other units, planes,
and land sectors.

Note that non-spy units require military on-board in order to be able  to  see
anything.

The various ranges over which lookout is effective break down into two groups:

UNIT to UNIT

  This range is dependent on both the visibility of the  unit  being  observed
  and the visual range of the observing unit.  (see info Unit-types)

UNIT to PLANE

Planes are treated as if they had a visibility of 10.
  For example:
     [##:##] Command: lookout 24

       Groonland (#2) jf4 jet fighter 4 #3 @2,-2
       Groonland (#2) airfield 100% efficient with approx 50 civ @ 2,-2
       Groonland (#2) highway 20% efficient with approx 20 civ @ 3,-1
       Groonland (#2) highway 0% efficient with approx 0 civ @ 0,-2

A map gives you a graphic representation of all or part of your country.

Your  own  sectors  show up as a designation mnemonic (see Sector-types) while
sectors held by other countries appear  as  question  marks  (?).   Mountains,
wilderness areas, and seas appear as '^', '-' and '.' respectively.

You can also get an lmap by typing 'M' at the march prompt.

Examples:
   [##:##] Command: map -9:18,-8:5

   [##:##] Command: map # >mapfil
where your realm (or '#', see info realm or info  update)  is  -5:5,-6:6  will
type out a 11 by 13 sector map and also put the map in the file called mapfil.

Also, if you give a ship # instead of coordinates or a realm,  map  will  show
you a small realm around the given ship (assuming you own it).

If  you use nmap, you can get a map that shows new sector designations instead
of old sector designations of your own country.

If you use lmap, you can get a map around a land unit, instead. Pmap does  the
same for a plane. Smap does the same for a ship.

MAP FLAGS

If you give an 's' flag, all your ships will be shown on the map.  An 'l' flag
does the same for land units, and a 'p' for planes.

NAME
   lmine - Mine a sector with an engineering unit

Level: Expert

SYNTAX
   [##:##]% lmine  

This command causes a unit with the engineering ability to lay mines in a sec-
tor. (see info Unit-types).  If you ask to lay more mines  than  the  unit  is
carrying,  then  it  will  attempt to keep resupplying itself until all of the
mines have been laid.  It costs 1 mobility point per mine laid, so an engineer
with  20  mobility can lay a maximum of 20 mines.  The 'strength' command will
list how many mines you have put in each sector.

See info Hitchance for the chance of something hitting a land mine.

If a defender in land combat has land-mines in the sector, he receives a bonus
to  his  defense.  See  info attack for more information.  If the attacker has
engineering units with him, the bonus is less.

In the command syntax  is the number of one of your units  and  
is  the  number  of  mines  you wish to lay.  That number of shells, (assuming
you've got them), will be dropped in the sector that unit occupies,  magically
becoming mines.

You need not fear mines in sectors that you are the old owner of. This is nor-
mally all your sectors. When you capture a mined  sector,  however,  you  will
need to worry about those mines until you become the old owner of that sector.
Once you are the old owner of a sector (i.e when you get the  message  "Sector
x,y  is now fully yours."), you have the mines located, and will no longer hit
them.

If you are in a captured sector, and the original owner attacks, you will  not
get the mine bonus (as he knows where all the mines are)

Mines  can  only  be  removed  safely  by a unit with the engineering ability.
(Other units can remove them by hitting them, but...)  Engineering units  mov-
ing  through  a  sector with unlocated mines will attempt to remove them.  The
number of times each engineer sweeps for mines is equal to 2 times the  number
of  mines  it  can  carry.   The chance of the engineer finding a mine on each
sweep is equal to 50% times its 'att' value (see  show  land  stats).   If  an
engineer  sweeps  more  mines than it can carry, then it will drop the rest as
shells into the sector.

NAME
   load - Load goods, people, etc onto a ship

Level: Basic

SYNTAX
   [##:##]% load   

SYNTAX
   [##:##]% load plane  

SYNTAX
   [##:##]% load land  

The  load  command  carries out the loading of ships.  Commodities (like guns,
civs, food) can be loaded onto any ship.  Missiles can  be  loaded  onto  nuke
subs  and  planes  can be loaded onto carriers.  Land units may be loaded onto
many ships.

The ship(s) must be in a harbor and the harbor must be at least 2%  efficient.

SYNTAX
   [##:##]% load   

In  the first form, the amount argument specifies the amount of the given com-
modity you wish to load on each ship specified.   Amounts  greater  than  that
allowed  will  be truncated to the maximum possible. Amounts less than 0 indi-
cate that you want to make the ships have that amount. If the ships have  less
than  that  amount,  more  will  be  loaded.  If the ships have more than that
amount, the commodity will be unloaded. For example,

   [##:##] Command: load food 3 -100

will cause ship 3 to load or unload food so that it has 100.  If  it  had  120
food, 20 would be unloaded. If it had 50 food, 50 would be loaded.

SYNTAX
   [##:##]% load plane  

In  the  second form, where you say plane instead of say civ planes are loaded
onto ships. Multiple planes may be given. Some may not be loaded, if there  is
not enough room.

SYNTAX
   [##:##]% load land  

In  the  third  form,  where you say land instead of say civ, a unit is loaded
onto a ship. Multiple units may be given. Some may not be loaded, if there  is
not  enough  room. (Note that planes on land units on ships can't be used, and
units on ships generally can't do much, like  firing,  marching,  etc).   When
loading a land unit onto a ship, the unit will check to see that it is in sup-
ply before stepping on deck.  If it isn't, then it will try to resupply itself
(see  info  supply)  and  if  it is not able to do that, then you are issued a
warning.  Sailors don't like to go to sea without supplies.

See info Ship-types for a table of the maximum amounts of each items that  can
be carried on each ship type.

If you are loading things onto FRIENDLY ships, you need to type the numbers of
the ships, fleets or realms will not work. I.e. if you  do  "load  f  s  999",
it'll  load  999  food onto all your ships in fleet s. If you do "load 1/2/3/4
999 f", it'll try to load food onto ships  1,  2,  3,  and  4,  regardless  of
whether they're yours or they belong to a friendly trading partner.

If  you  load  something  onto a friendly nation's ship, it becomes his and he
gets a telegram. If you load a unit, he gets any planes it may be carrying.

If you unload a plane or unit in a friendly nation's harbor, it  becomes  his.
If you unload a unit, he gets any planes it may be carrying.

Note  that if any of ,  or  does not start with a number
(e.g. it is of the form "s" or "*" or "#1" and not of the form 123  or  12,14)
then  you  will not be given any error messages.  This is so that you can type
something like "load land * *" without getting a hundred error messages.

NAME
   lookout - Check from ships for other ships and/or sector types

Level: Basic

SYNTAX
   [##:##]% lookout 

The  lookout  command allows ships to report sightings of other ships and land
sectors.

The various ranges over which lookout is effective break down into two groups:

SHIP to SHIP

  This  range  is  dependent on both the visibility of the ship being observed
  and the visual range of the observing  ship.   (see  info  Ship-types)  Sub-
  marines  at  sea  are a special case - they cannot be seen by simply looking
  out from a ship!  In order to detect subs at sea, you  need  to  use  sonar.
  Submarines have a very limited range for what ships they can see using their
  periscope--they can usually only see ships in the same sector.  However, all
  ships  (including  subs)  which  are  docked in a harbour are visible to all
  ships (including subs) in adjacent sectors.  (see also info sonar)

SHIP to SHIP

This range is effectively 1.0.
  For example:
     [##:##] Command: lookout 24

       Groonland (#1) patrol boat #10 @-13,7
       Curmudgeon (#4) heavy cruiser #36 @-14,6
       Groonland (#1) oil derrick #41 @-14,6
       Groonland (#1) tender #53 @-14,6
       Groonland (#1) mine 100% eff with approx. 300 civilians @-12,6
       Groonland (#1) heavy manufacturing 23% eff with approx. 10 civilians @-11,7

NAME
   lost - Report lost items

Level: Basic

SYNTAX
   [##:##]% lost

The  lost  command  displays all lost items currently in the database for your
country.

All lost items are timestamped at the time they were lost.  If you had a  pre-
viously  lost item in the database, and then build a new item of the same type
with the same id, or regain an item of the same type with the same id,  it  is
removed from the database.  This is done because the new item will now show up
in the other dump commands, and is no longer lost.

Lost items are kept in the database for 48 hours (default)  but  may  be  kept
longer  at  the  deity's  discretion.  Also, issuing the lost command does not
remove items from the database.  That is  where  the  timestamp  functionality
becomes important.

While  the lost command does not take any arguments, it does take the standard
syntax for selecting information.  (see info Selector).

A typical usage might be:
   [##:##] Command: lost ?timestamp>854954677
which would list data for all lost items timestamped after 854954677.  (Times-
tamps are kept in system seconds.)

A lost command lists all the lost items headed by:

   Sun Feb  9 22:16:37 1997
   DUMP LOST ITEMS 855544597
   type id x y timestamp

The  first  line is the date.  The second line is the "DUMP LOST ITEMS " where the  field is the current timestamp.  The  third  line
is the columns which are output.

These columns represent:

      type  The type of lost item.  They are as follows:

                                      0 - Sector
                                      1 - Ship
                                      2 - Plane
                                      3 - Land unit
                                      4 - Nuclear stockpile

        id  The  #  of the ship, plane, land unit or nuke.  All of these items
            are identified by id.  Sectors are identified by x and y.
         x  The x coordinate of the lost item when it was lost.
         y  The y coordinate of the lost item when it was lost.
 timestamp  The timestamp of when the item was lost.

SYNTAX
   [##:##]% lretreat [ | ] [] []

The retreat command allows you to examine or modify the retreat paths and con-
ditions of your ships or units. The following description is for  ships.  Land
units  are  exactly the same, except of course that some of the retreat condi-
tions (being sonared, depth charged, etc) don't apply.

The  and  arguments are provided to specify which ships  to
view  or  give  orders  for.  If  a fleet designation is given when specifying
orders, the orders apply to all ships within that fleet.

Retreat expects an argument.  To see every ship you own, give it the  argument
'*', or type "retreat *".

The report format contains the following fields:

    shp#  the ship number
shiptype  the type of ship; patrol boat, submarine, etc,
     x,y  the ship's current location (relative to your capital),
     flt  the fleet designation letter (set by fleetadd command),
    path  the ship's current retreat path.
 as_flt?  whether or not the ship's retreat path is a fleet retreat path
   flags  what conditions the ship will retreat under

For example:
   [##:##] Command: retreat *

   shp#     ship type       x,y   fl path       as flt? flags
      0 battleship 4        2,0      jjuuj              I
   1 ship

Overview

A player may give retreat orders for a ship or a fleet. Retreat orders include
a set of conditions that determine when the fleet/ship  will  retreat,  and  a
path that the fleet/ship will follow. When a condition is met for a particular
ship, the as flt? field is checked. If it is Yes,  then  every  ship  in  that
fleet  with  fleet  retreat orders retreats along the specified path. If it is
no, then the retreat orders apply to  that  ship  only,  and  only  that  ship
retreats.

When a ship is added to a fleet, it is given the retreat orders of that fleet,
if any exist.

Retreat orders are wiped when a ship navigates.

Retreat conditions at present include:

          Condition Meaning
          I         Retreat when the ship is injured,
                    i.e. whenever the ship is damaged
                    by fire, bombs, or torping.
          T         Retreat when a sub torpedos or tries
                    to torpedo the ship.
          B         Retreat when a plane bombs or tries
                    to bomb the ship.
          S         Retreat when the ship detects a sonar
                    ping.
          D         Retreat when the ship is depth-charged.
          H         Retreat when helpless. A ship is helpless
                    when it is fired upon, and no friendly
                    ships/sectors (including the ship itself)
                    are able to fire back at the aggressor.
          C         Clear the flags

For example, if the battleship above was fired at, it would attempt to retreat
2  sectors,  jj,  using the normal amount of mobility for moving 2 sectors. It
would then look like:

   shp#     ship type       x,y   fl path       as flt? flags
      0 battleship 4        2,0      uuj                I

   lstat - Report statistics of unit, army or units in a given area

Level: Basic

SYNTAX
   [##:##]% lstat [ | ]

The  lstat  command  is  a  report of the varying statistics of your units and
lists the info in a readable format.  Since your  units'  statistics  vary  by
tech  level,  this  is a very useful way to see what the attack, defense, etc.
modifiers are on a per-unit basis.

The  and  arguments are provided in case you  only  wish  to
look at one unit or one army or all units within a given area.

Lstat  expects  an  argument.  To see every unit you own, give it the argument
'*', i.e. type "lstat *".

The report format contains the following fields:

     lnd#  the unit number
     unit  the type of unit
      x,y  the unit's current location (relative to your origin),
      eff  the unit's efficiency,
     tech  the tech level of the unit
      att  the attack multiplier of the unit
      def  the defense multiplier of the unit
      vul  the vulnerablilty of the unit (see "info Damage")
      spd  the speed of the unit (see "info Mobility")
      vis  the visibility of the unit
      spy  the distance a unit can see
      rad  the maximum reaction radius of the unit

The lunload command is the opposite of lload and follows the exact same syntax
...  so why look here for documentation?

The only thing to know is that lunload won't unload more of  a  thing  if  the
sector already has 999. For example, if a unit has 10 food, and the sector has
994, you can only unload 5 of the 10 food.

NAME
   march - Move a land unit or units

Level: Basic

SYNTAX
   [##:##]% march  

The  march command is the move command applied to land units.  You can control
one unit or an entire army with it.

Land units may only move into sectors you own, sectors of  countries  you  are
allied  with  or deity-owned sectors with 1 exception.  Spies.  Spies may move
anywhere, with a chance of getting caught.  See "info Spies" for more informa-
tion.

If you are moving an army and the lead unit stops, the army stops; (the lowest
numbered unit is always considered the lead unit).

The program will prompt with the mobility of the lead unit, the minimum mobil-
ity value for the army, and the current sector coordinates in the form:

   <57.0:23.5: -6,4>

which  means  the lead unit has 57 mobility units, some other unit in the army
has 23.5 mobility units and the lead unit is in sector -6,4.  You may indicate
the  direction  you  would like the army to move by typing a string of letters
consisting of any combination of the following:

   y  for up-left
   u  for up-right               y    u
   g  for left                    \\  /
   j  for right               g  --  --  j
   b  for down-left               /  \\
   n  for down-right             b    n
   r  for radar
   l  for lookout
   m  to sweep landmines
   h  for end of movement

The radar option will cause the lead unit to use it's radar, if any.  You  may
also  give  a  unit  number  or  army  or  group of units on the same line: "r
12/13/14/73"

The lookout option works in the same way as radar, i.e. it will cause the lead
unit to do a lookout.

Note:  the  lookout  and radar commands use BTU's, just as if you'd typed them
separately from the command line.

You may also use the 'm' command to  have  engineers  in  the  marching  group
search for mines in the current sector. Example: "m 12"

Since  the  can be specified in the command line, simple unit movements
are often typed as a single line, such as:
   [##:##] Command: march 19 jjjh

Or some movements may be done partly on the command line and  partly  interac-
tively:

   [##:##] Command: march 18 yy

   <112.7:112.7: -4, -2> l
   Your capital 100% efficient with 549 civ with 10 mil @ -5,-3
   Your highway 100% efficient with 549 civ with 0 mil @ -4,-2
   Your harbor 100% efficient with 549 civ with 109 mil @ -3,-1
   <112.7:112.7: -4, -2> yh
   war band #18 stopped at -5,-3

You  may  also  simply  specify the destination sector on the command line. In
this case, empire will set the path to be  the  cheapest  path  (in  terms  of
mobility) that currently exists. The unit(s) will move to the destination sec-
tor, and then ask for more input.

For example,
   [##:##] Command: march 18 -6,-2

   <104.2:104.2: -6,-2> h
   war band #18 stopped at -5,-3

Note that if you are marching multiple units, you may only specify a  destina-
tion sector on the command line if all the units start in the same sector.

See "info Mobility" for the mobility cost to march land units.

At  the update, units with negative mobility have their mobility halved before
new mob is added. For example, in a game where units got 32 mob per update,  a
unit  with -100 mobility would have -18 after an update.  (-100/2 = -50 + 32 =
-18) This helps inefficient units be not quite as slow.

Moving a unit through a sector that has been  mined  introduces  a  chance  of
mines/(mines + 50) that you will be damaged.  Units with engineering capabili-
ties can remove up to five mines per pass through a sector (indicated  by  the
message  Sweep...).   Such  units also take 1/2 normal damage from mines.  See
info lmine for more details.

Hostile land/sea/air units may fire at/bomb your units, if they're  on  inter-
diction missions (see info mission).  If your enemy has a stack of missiles on
interdiction mission, then they will  automatically  fire  one  after  another
until 100 damage has been done.  Missiles and pinbombers have a 100% chance of
hitting their target (provided they make it through  plane/missile  defenses).
Collateral  damage  will  be  done  to the sector that the units were marching
into.

NAME
   mine - Drop sea mines from a ship

Level: Basic

SYNTAX
   [##:##]% mine  

This  command  drops  mines in the sea and is functional from ships with mine-
laying capability (see info Ship-types).

See info Hitchance for the chance of a ship hitting a mine.

In the command syntax  is the number of one of your ships  and  
is  the  number  of  mines you wish to drop.  That number of shells, (assuming
you've got them), will be dropped in the sector that ship occupies,  magically
becoming mines as they hit the water.

Mines  can  only  be removed safely by a minesweeper.  (Other ships can remove
them by hitting them, but...)  Planes with the 'sweep' ability can clear mines
by  flying recon missions through mined sectors, with each passage through the
sector possibly removing some mines.

Ships of tech 310 or higher can detect mines with their sonar.  See info sonar
for more information.

Harbors  and  sea  sectors  under  bridge spans can be mined.  Your ships will
automatically avoid these mines when passing through, (and  your  minesweepers
will not not pick them up).

Note  that the sector is checked for possible mine hits only when a ship moves
into it; thus, a ship may safely drop mines in a sector and then move out.  On
the other hand, the mines know no allegiance, so moving back into a mined sec-
tor is foolish at best unless it is a harbor or under a bridge span.

Mines in the same sector as a bridge that collapses are cleared.

Here is a summary of which units can be put on which missions:

    air defense        no     yes     no          no  only "intercept"

You  may  also  use  'q'  (query) to check on the mission of something, or 'c'
(clear) to wipe the mission of a land unit/plane/ship.

GENERAL CONCEPT

Missions are things that your planes/land units/ships  can  do  automatically,
such  as  bombing/shelling.  You  assign a unit to a mission, and whenever the
right conditions occur, the unit attempts to perform its  mission.  Note  that
missions don't allow a unit to do anything it normally could not do, they sim-
ply allow them to do it in an automatic fashion. In some cases, units perform-
ing  missions  might  not be as 'smart' as they would be if you were operating
them personally.  That's the price you pay for having automatic defenses.

IMPORTANT NOTES

Missions can occur  during  updates.   (Interdicting  ships  using  "sail"  or
"order").

Artillery units less than 20% efficient will not fire.

Planes  flying  missions  will  be intercepted normally. (i.e. if you fly over
enemy territory, you'll get intercepted. Any mission except air  missions  may
also be intercepted by planes on air defense missions)

Planes of less than 40% efficiency will not fly missions.

Planes  assigned to missions are NOT eligible to intercept normally. For exam-
ple, if a fighter is assigned to an escort or air-defense or  interdiction  or
support  mission,  it  will  NOT  rise  to intercept an intruding enemy plane.
(planes on air-defense missions will intercept planes flying in their op-area,
in accordance with the air-defense mission, but will not intercept one outside
their op-area, even if it is within their normal range. Be sure you understand
this before using plane missions.)

Nukes on missiles or planes flying missions DO detonate.

"marine"  missiles  will  keep  launching  to interdict ships until all of the
valuable ships in the fleet are sunk.  A "valuable" ship is one which cost  at
least  $1000 to build or can carry land units or planes.  For each new missile
launched, the most valuable ship according to (cost to build) * efficiency  is
targeted.

Non-marine missiles will keep firing on a sector until 100 damage is done.

OPERATIONS SECTORS

Some  missions require the designation of an 'op sector', short for operations
sector. This is the center of an area that the mission is focussed on.  The op
sector  may be any sector that is within the unit's range.  (Firing range, for
ships & land units, flying range for planes, changeable with rangeedit).   The
unit  will  exert influence in a radius around the op sector.  By default, the
radius will be as large as possible,  i.e.  the  biggest  range  so  that  the
unit/ship/plane could legally act there.)  For example, a ship with a range of
4 could designate any sector up to 4 away from it as it's op sector, and would
affect  anything  within 4 of it's op-sector, provided it was also within 4 of
the ship.

If a smaller radius is desired, it may be specified on the command line. If it
is not specified, it will not be prompted for.

The area affected by a unit is known as that unit's op-area.

If  a '.' is given as the op-sector, the op sector will be the location of the
unit.

Additionally, if the unit's op-sector is the sector the unit is  in,  and  the
unit  moves  without losing its mission status, the operation sector will move
with it. (Normally, of course, the only way for a unit on a mission to move is
to be carried on a ship, so this mostly applies to planes on carriers) Thus, a
tactical bomber on a ship could have an op-area centered on the  carrier  that
moved with the carrier.

Otherwise,  if the unit moves without losing its mission status, the op sector
will stay where it was designated.

For example, suppose that land unit 4 is an artillery unit, range  5,  located
at 0,0.

   [##:##] Command: mission land 4 int .

This  would  make  the unit interdict anything passing within 5 sectors of its
location.

   [##:##] Command: mission land 4 int 4,0

This would make the unit interdict anything passing within 5 sectors  of  4,0,
provided it was also within 5 sectors (the unit's range) of 0,0.

   [##:##] Command: mission land 4 int 4,0 2

This  would  make the unit interdict anything passing within 2 sectors of 4,0,
provided it was also within 5 sectors (the unit's range) of 0,0.

The op-sector/op-range concept allows you to restrict a unit's area of  inter-
est to a small, important area, or just let it shoot at anything within range.

MOBILITY USE

When a unit is given a mission, it costs no mobility.  When  a  unit  performs
its  mission,  it  uses the normal mobility costs that it would use to perform
that mission if done by the player.

A unit stays on its mission until you cancel it, OR the unit acts. Any type of
action  not a part of a mission is sufficient, so marching, navigating, trans-
porting, flying, reconing,  bombing,  mining,  paratrooping,  being  attacked,
being  paratrooped on, retreating, etc, will all cause a unit to lose its mis-
sion status, but the unit could bomb/shell/etc AS PART OF A MISSION, and still
retain  its mission status.  Also, land units with a reserve mission can react
to a threatened sector and fight, and (assuming  they  win)  return  to  their
original sector without losing their reserve status.

Note that fortifying a unit does not affect it's mission status.

DEFENDERS

The   defender's   planes   will   intercept   planes  flying  missions.   His
ships/forts/units, however, will NOT fire at  ships/forts/units  firing  on  a
mission.

INTERDICTION MISSIONS (ships, planes, land units)

When  giving  a  unit a interdiction mission, you designate an op sector. From
then on, whenever an enemy (defined as something belonging to a  nation  which
you  are  at war with) moves in a sector in that unit's op-area, the unit will
try to shell or bomb it (as appropriate). Almost any kind of movement,  except
for  distribution movement during an update, and the tiny amounts moved by the
supply routines is enough.

For  example,  an  enemy  land  unit  marching  up  to  the  front  would   be
shelled/bombed.  An enemy moving commodities around would have the commodities
automatically shelled/bombed. A ship navigating into a  sea  sector  would  be
shelled or bombed, depending on it's type (obviously, only depth-charge or ASW
capable units would affect a submarine, and  a  submarine  would  only  affect
things  it  could torpedo) In general, units can only affect things they could
normally affect. For example, if the enemy was transporting a  plane  along  a
highway,  and  you  had  an artillery unit and a light bomber interdicting the
highway sector, the land unit would fire and the bomber would  fly  there  and
bomb, and the total damage would be applied to the plane being transported. If
it was still alive,  it  might  be  moved  to  another  sector,  there  to  be
bombed/shelled  again  (assuming  the  new  sector was also in both units' op-
areas) If a different unit later moved in, it would  be  shelled/bombed.  This
happens as long as the interdicting units have mobility left.

Damage  done  is divided amongst all units/ships/commodities moving. For exam-
ple, if 6 ships were moving, and the interdiction mission did 18 pts  of  dam-
age, each ship would take 3.

Note  that  only ships with sonar and ASW planes can interdict subs. Also, the
units may or may not detect the subs, so it's kind of random. The sub also has
a chance of escaping the damage, depending on the visibility of the sub.

Only  planes  with the 'tactical' ability can fly interdiction missions.  Only
planes with 'ASW' ability will fly vs. subs. Planes with  'ASW'  ability  will
not fly interdiction vs. other types of ships/planes/units/commods.  Subs have
a chance of sneaking through ASW  aircover  unnoticed,  and  ASW  planes  will
respond  to any non-Friendly sub movement.  Depending on the visibility of the
sub, the ASW plane may or may not identify the type and/or owner of the sub.

Interdiction has no effect on flying  planes.  Interdiction  does  not  affect
loading/unloading.  It will also cause some damage to the sector that the com-
modities were moving into.

Note also that forts will fire at enemy ships coming within range.  You  don't
have  to  set  anything  for  this, it happens automatically. (Forts firing at
enemy ships naving happens before ships/planes/units interdicting ships, so if
the enemy is using an area a lot, a fort will hurt him without costing you mob
from planes)

SUPPORT MISSIONS (planes only)

A support mission allows your planes to automatically bomb the enemy.   Planes
with  offensive  support  missions  will  bomb  enemy sectors that you attack.
Planes with defensive support missions will bomb enemy troops  attacking  your
sector,  adding to your defensive strength. Planes with support orders will do
both.

When giving a plane a support mission, you designate an op sector.  From  then
on,  whenever a sector owned by the plane's owner (or by an ally of the plane-
owner, if the ally is also at war with the attacker) in that  plane's  op-area
is attacked, the plane will attempt to fly to that sector and give ground sup-
port, if it has support or defensive support orders.

If the plane's owner (or an ally of the plane's owner, if the ally is also  at
war  with  the  country  attacked)  attacks  a  sector in that plane's op-area
belonging to a country that the plane owner is at war  with,  the  plane  will
also  attempt  to  fly  there  and give offensive support if it has support or
offensive support orders.

(see info attack for more information on how support works in land combat)

Only planes with the 'tactical' ability can fly support missions.

ESCORT MISSIONS (planes only)

When given an escort mission,  an  escort  or  intercept  capable  plane  will
attempt  to  escort  any  plane flying a support or interdict mission from the
same airport.  If even 1 plane flies a support or interdiction mission from an
airport,  all  planes  on  escort duty at that airport will attempt to escort.
Planes with escort duty will NOT attempt to  escort  planes  taking  off  from
other  airports,  so  it  pays to put your bombing planes and escorting planes
together.

Only planes with the 'escort' or 'intercept' abilities  can  fly  escort  mis-
sions.

AIR  DEFENSE  MISSIONS  (planes  only)  When  given an air defense mission, an
intercept capable plane will attempt to intercept any enemy plane (defined  as
any  plane  belonging  to a country you re at war with) flying into its opera-
tions area, irregardless of whether the enemy planes  are  flying  over  owned
sectors.  For  example,  if a plane is given an air defense mission with an op
area covering some owned sectors, some sea,  some  allied  sectors,  and  some
enemy sectors, it would try to intercept over any of them.

When a plane enters a sector, any planes with air defense missions that are at
war with the owner of the plane will fly there to fight it.  The  air  defense
planes  encounter  normal  interception along the way (but do NOT trigger more
air defense missions, but MAY be intercepted normally).  Once the air  defense
planes get to the sector, they fight the plane. Then, if the owner of the sec-
tor is hostile to the plane, still more planes may intercept it.

Example  Groonland wants to run a recon flight over Bannannarama. Joeland  has
a jet fighter with an air defense mission and an op-area covering part of Ban-
nannarama. The 'j' sector belongs to Joeland, and is the base for the fighter.
The 'b' sectors belong to Bannannarama, which has 1 fighter in the center sec-
tor. The 'g' sector belongs  to  Groonland.  Assume  that  all  countries  are
mutually at war.

The Joeland fighter's op area is centered on the 'B', radius 2.

    . . . . . . . . . . . . . . . . .
     . . . . . j . . . . . b b . . . .
    . . . . . . . . . . . b B b . . .
     . . . . . . . . . . . b b . . . .
    . . . . . . . . . g . . . . . . .

The  Groonland  player  enters  a  path  of  'uujjjbgbggh'.  The first sectors
entered is sea, and is not in the Joeland aircraft's op-area, so nothing  hap-
pens.

Next, the Groonland plane enters the sector adjacent to Bannannarama.  This is
within the Joeland aircraft's op-area, so it flies to intercept.  It takes the
shortest path there, and fights the Groonland plane.  Let's say that both take
20 points of damage, and neither aborts.

Next, the Groonland plane overflies a Bannannarama sector. The  Joeland  plane
flies  there,  and is intercepted by the Bannannarama plane. Let's say that it
comes through the fight without being aborted. It then  fights  the  Groonland
plane.  After  this  combat,  if the Groonland plane is not aborted, it may be
intercepted again by the busy Bannannarama fighter, assuming that  that  plane
is still efficient enough, has mob enough, etc.

A good use of this mission is to provide a wider CAP around a carrier, so that
enemy planes get intercepted several times on the way to the  carrier,  rather
than just once, in the carrier's sector.

Another  use  is to provide air-cover for an ally who has temporarily lost his
planes.

RESERVE MISSIONS (land units only)

A land unit given reserve orders has an increased ability to  react  to  enemy
attacks.  A  reserve unit has its reaction radius increased by 2.  (Note: this
is cumulative with the +1 modifier for being at an efficient headquarters,  so
a  reserve  unit  at an HQ would have a +3).  In addition, a reserve unit pays
1/2 the normal cost for fighting a battle.  (It still pays the normal cost for
moving to the threatened sector) See info attack for more details on reaction.

Note that units with a reserve mission retain this status,  even  though  they
move  to  the threatened sector and return. This is an exception to the normal
rules on losing your mission status. If, however, the land unit is  forced  to
retreat  from the combat (see land combat for details), it WOULD lose its sta-
tus.

When a unit with a reserve mission is listed, the op sector is the sector  the
unit is in, and the radius is the units maximum reaction radius, including the
bonus for the reserve mission and HQ (if applicable).  Note  that  the  unit's
actual radius might be different if it was changed by lrangeedit.

Note: information gained from planes flying missions is automatically added to
your bmap.

The  mobupdate  command  will disable mobility updating for 'X' minutes.  Note
that this only works if the MOB_ACCESS option has been enabled.

Using this command with 0 minutes will turn mobility updating back on.

Using this command with 'check' or a negative amount of minutes will tell  you

NAME
   morale - Change the retreat percentage of a unit

Level: Expert

SYNTAX
   [##:##]% morale  

The morale command is used to set the retreat percentage of land units.

Normally,  a  land unit must start making morale checks during combat when its
efficiency is less than or equal to its retreat percentage.   (The  chance  of
failing  a morale check is: sqrt(100-effic)%/(men in unit).  Example: a 25 man
unit is at 75% efficiency.  It's  chance  of  failing  is  sqrt(100-75)%/25  =
sqrt(25)%/25 = 20%)

The  morale  command  allows you to adjust this percentage within a range. If,
for example, you wish only to trade space for time, you could set the  retreat
percentage  to  100%,  meaning  that your units would retreat often, but would
still slow the enemy down a bit. Or, you could set your retreat percentage  to
the minimum, and make the unit stick around and fight more, but at the cost of
more casualties.

The maximum allowed value is 100% (i.e. start making morale checks  after  any
casualties) The minimum values is based on happiness:
   (morale_base) - happiness

"morale_base" is a deity settable variable, which defaults to 42.  When a unit
is first built, it's retreat percentage is set to "morale_base".

Level: Basic

SYNTAX
   [##:##]% move    

The  move  command is crucial to Empire; it carries out the movement of civil-
ians, military, ore, guns, shells, food, planes, etc. on land.  Note that  you
can  only move into sectors that you own, so you cannot take sectors via move.
To take sectors, use the "explore" command, which  uses  the  same  syntax  as
move.

 can be any one of:

   c       civilians
   m       military
   u    uncompensated workers
   f       food
   g       guns
   s       shells
   p       petrol
   i       iron ore
   d       gold dust
   b       bars of gold
   l       light construction materials
   h       heavy construction materials
   r    radioactive materials

If    is  not provided in the command line, the program will request the
starting sector then display the number of mobility units in that sector,  its
designation, and its coordinates in the form:

   <97.0: a -6,4>

which  indicates  97  mobility  units  in  agribusiness  sector -6,4.  You may
respond with any combination of:

   y  for up-left
   u  for up-right               y    u
   g  for left                    \\  /
   j  for right               g  --  --  j
   b  for down-left               /  \\
   n  for down-right             b    n
   v  for view
   m  for map
   h  for end of movement

The view command shows the sector efficiency and some of the contents  of  the
sector you are currently occupying.

Since  the   can be specified in the command line, simple movements are
often typed as a single line, such as:
   [##:##] Command: move m 2,0 20 jjjh
Or some movements may be done partly on the command line and  partly  interac-
tively:
   [##:##] Command: move c 2,2 18 jj

   <32.3: g 6,2> v
   10% gold mine with 3 civilians.
   <32.3: 6,2> h

You may also simply specify the destination sector.  In this case, empire will
set the path to be the cheapest path (in terms of mobility) from  the  current
sector to the destination sector, if such a path exists.

For example,
   [##:##] Command: move c 2,2 18 6,2

Military control

In  order  to  move  something (other than mil) out of a sector, you must have
military control of the sector. Military control is defined as having  mil  in
the sector equal to at least 1/10th the number of unconverted civilians there.
Units count as if they were straight mil, i.e. a 100% unit that  contained  50
mil would count as 50 mil for the purposes of control)

Mobility  See  'info Mobility' for a description of how much mobility it costs
to move something.

Mines  Note that while moving, you might hit mines. The more stuff you're mov-
ing,  the  greater the chance of setting off any mines in the sectors you move
through. See info lmine for more details.

Interdiction  Any enemy units on interdiction mission may be triggered by  the
move (the more you move, the bigger the chance they interdict).  The interdic-
tion will damage the goods you are moving, and will also cause some damage  to
the sector you were moving into.

Unhappy civilians

Also, when moving unhappy civilians (work percentage less than 100%), unhappi-
ness is contagious. If you move even 1 unhappy civilian into a sector, the new
sector's  work  percentage is set to the level of the civilian being moved, if
that is less than the existing level.

However, if the NEW_WORK option is enabled, the work percentage of the  desti-
nation  sector  is computed by averaging the incoming civ's happiness with the
happiness of the civs already there. For example, say you move 100  civs  with
work  percentage  of  0%  into  a  sector with 100 fully happy civilians (100%
work). If NEW_WORK is enabled, the work would be:
   ((migrants * their work) + (people at dest * their  work)  /  (total  civs)
((100 * 0%) + (100 * 100%)) / (100+100) =  100/200 = 50%

Plague  If  a  sector  is infected with the plague, then anything moved out of
the sector will infect the sector that it moves into.  Note that sectors moved
through will not catch the plague.

NAME
   mult - Set price multipliers of goods

Level: Expert

SYNTAX
   [##:##]% mult  

The  mult  command  allows a nation to set price multipliers of the goods they
are selling.

The  argument is the number or name of the nation  for  which  you
want  to reset the multiplier, and  is the new multiplier (a floating-
point number). If no arguments are given, you are prompted for  them.  A  car-
riage return or incorrect nation at this prompt allows the changing of all the
price multipliers.

For example, if one nation is a  nice  nation,  and  another  is  particularly
unfriendly,  the  price  multiplier  for the nice one might be 0.75, while the
nasty nation might have one around 5.

The price multiplier affects the price of a nation's goods to  other  nations.
Final  item  price  is  determined by multiplying the price of the item at the
time of the sale by the individual price multiplier for the nation buying  the
item.  You cannot have a price multiplier below 0.05.

Typical output looks like:
   [##:##] Command: mult

   for which country? bar
   bar (  1.000) : 3.00

   [##:##] Command: mult

   for which country?

   MGM (1.00) :
   hodedo (2.55) : 100
   bar (1.00) : ^C

The second editing session left unchanged all price multipliers except the one
for country hodedo, which was set to 100.

   Technology factor : 30.81%      Max population : 556

   Plague factor :   1.05%
   Max safe population for civs/uws: 427/483
   Happiness needed is 4.385283

If the RES_POP option is in use, there will be a line that tells you the maxi-
mum  number  of civs you can have in a sector without losing them (999 without
this option), and the maximum number of civs you can have in a sector  without
losing population growth.

If  the  NO_PLAGUE  option  is  not  used, you'll also see a line that has the
plague chance for your nation.

The max safe population is the highest population in a sector  that  will  NOT
forfeit some population growth during an update.  In the example above, if you
have 427 civs in a sector, you are guaranteed not to have more than 556  after
population  growth.   If  you have more than 427, population growth would make
you go over 556, and the excess babies would be eliminated when the population
was reduced to 556.

If  you  have at least the happiness mentioned in the last line, your sector's
loyalty won't have a chance to go down. Otherwise, each update, the chance  is
the  number  above  - your happiness / 5.0.  For the country above, the chance
would be (4.385283-2.01)/5.0 = .475 = 47% chance that any individual  sector's
loyalty would go down.

NAME
   navigate - Move ship or fleet around

Level: Basic

SYNTAX
   [##:##]% navigate  

The  navigate command is the move command applied to the sea.  You can control
one ship or an entire fleet with it.

A ship must have at least one crew (which may be civilian or military, but not
an  uncompensated worker) to be navigated.  When you navigate, you see the hex
of sectors around the flagship.  (The lowest numbered ship is  always  consid-
ered the flagship).

The  program will prompt with the maximum and minimum mobility of the ships in
the fleet, and the current sector of the flagship in the form:

   <57.0:23.5: -6,4>

which means one ship has 57 mobility units, some other ship in the  fleet  has
23.5  mobility units and the flagship is in sector -6,4.  You may indicate the
direction you would like the fleet to move by typing a string of letters  con-
sisting of any combination of the following:

   y  for up-left
   u  for up-right               y    u
   g  for left                    \\  /
   j  for right               g  --  --  j
   b  for down-left               /  \\
   n  for down-right             b    n

Other commands you may type while navigating are:

   M  for map
   B  for bmap
   f  to change flagship
   i  to list ships you are navigating
   v  to view oil content and fish
   r  for radar
   l  to look at land and nearby ships
   s  for sonar
   m  to sweep mines
   h  for end of movement

While  navigating  you may also use radar, sonar, or lookout.  (by entering r,
s, or l) By default it will radar, sonar, or lookout from  the  flagship.  You
may  also  give  a ship number or fleet or group of ships on the same line: "r
12/13/14/73"

You may also use minesweepers in  the  currently  navigating  group  to  sweep
mines. This costs them the equivalent of 1 sector's mobility.  For example: "m
12/13"

Since the  can be specified in the command line, simple ship  movements
are often typed as a single line, such as:
   [##:##] Command: nav 19 jjjh

Or  some  movements may be done partly on the command line and partly interac-
tively:

   [##:##] Command: nav 18 jj

   <112.7:112.7: -4, -2> v
   patrol boat #18 on open sea @ -3,-2
   <112.7:112.7: -4, -2> gh
   patrol boat #18 stopped at -6,-2

You may also simply specify the destination sector on  the  command  line.  In
this  case,  empire  will  set  the  path to be the cheapest path (in terms of
length) that currently exists. The unit(s) will move to the  destination  sec-
tor, and then ask for more input.

For example,
   [##:##] Command: nav 18 -6,-2

   <104.2:104.2: -6, -2> h
   patrol boat #18 stopped at -6,-2

Note that if you are naving multiple ships, you may only specify a destination
sector on the command line if all the ships start in the same sector.

The formula for the movement cost for 1 sector is:

        480 / (( speed + speed * (50+tech)/(200+tech) ) * Efficiency/100)

Moving a ship through a sector that has been  mined  introduces  a  chance  of
mines/(mines  + 50) of hitting a mine.  Minesweeps can remove up to five mines
per pass through a sector (indicated by  the  message  Sweep...).   Minesweeps
also take 1/2 normal damage from mines.

Also, note that some things may affect you while you are moving. Forts belong-
ing to hostile countries will fire at you when you come within range.  Hostile
land/sea/air  units  may  fire  at/bomb your ships, if they're on interdiction
missions (see info mission).  If your enemy has a stack of missiles on  inter-
diction mission, then they will automatically fire one after another until all
of your ships are sunk.  The chance of missiles and planes hitting your  ships
is  determined  by  the "worst" ship in your fleet (see bomb for the chance of
hitting).  Any damage incurred by the fleet is divided evenly  among  all  the
ships in the fleet which are in the same sector.

NOTE

While  navigating,  you  cannot enter a sector that belongs to another country
unless they have FRIENDLY relations with you. This includes bridges, and  har-
bors.

This command is designed to be used for input to an empire tool such as ve.

In  the  syntax  of  the  ndump  command  is the area on which you wish
information, (see info Syntax).

An ndump command lists all selected nuclear stockpiles headed by:

   Sun Feb  9 22:16:37 1997
   DUMP NUKES 855544597
   id x y num type

The first line is the date.  The second line is the "DUMP  NUKES  "
where  the   field is the current timestamp.  The third line is the
columns which are output.

id - The id of the stockpile the nuke is in.

x and y - The x and y coordinates of the stockpile

num - The number of this type of nuke

type - This type of nuke (100kt, 5mt, etc.)

A typical usage might be:
   [##:##] Command: ndump #5
which would list data for all nukes in realm #5.

A ndump lists each of your sectors in the specified area.  The header line  is
a list of fields that correspond to the order that ndump prints the nuke info.

Also, if you give a ship # instead of coordinates or a realm,  map  will  show
you a small realm around the given ship (assuming you own it).

If  you use nmap, you can get a map that shows new sector designations instead
of old sector designations of your own country.

If you use lmap, you can get a map around a land unit, instead. Pmap does  the
same for a plane. Smap does the same for a ship.

MAP FLAGS

If you give an 's' flag, all your ships will be shown on the map.  An 'l' flag
does the same for land units, and a 'p' for planes.

NAME
   offer - Offer a loan or treaty to another country

Level: Expert

SYNTAX
   [##:##]% offer loan    

SYNTAX
   [##:##]% offer treaty 

The  offer command is used to offer either a loan or a treaty to another coun-
try.

In the case of a loan:

     is the number or name of the country to whom you are offering
    the loan,

     is the size of the loan.  (NOTE: do not use a dollar sign),

     is the length of the loan in days,

     is the interest rate, (per ), on the loan.

    The  program  prompts  with  various questions concerning any terms of the
    loan not provided on the command line and sends a telegram to 
    announcing the loan offer.

    If  the  other country accepts the loan, (using the consider command), the
    money will be transferred from your account and you will be notified  that
    the loan duration has started.

    Note  that  the  dependence of rate on the duration makes a 30 day loan at
    10% a worse deal than a 60 day loan at 15%.

In the case of a treaty:

     is the name or number of the country  to  whom  you  wish  to
    offer the treaty.

    You  will  be  asked  to  set both the conditions for yourself and for the
    other country.

    The conditions from which you may choose are:

           Condition                 Command(s) affected
           no attacks on land units  lboard
           no attacks on ships       board
           no sector attacks         assault, attack, paradrop
           no shelling ships         fire
           no depth-charging subs    fire
           no shelling land          fire
           no enlistments            enlist
           no building               build

    Note that the first six terms apply to interactions between the  two  par-
    ties  to  the treaty while the last two apply to ANY actions of the speci-
    fied type.

    Once you have offered the treaty, a telegram will be  sent  to  the  other
    country  indicating  the  offer.  If the other country accepts the treaty,
    (using the consider command), you will be notified that it has  gone  into
    effect.

    Once  signed,  the  treaty  is not binding!  However, any violation of the
    treaty will be pointed out to the violator in time for him/her  to  recon-
    sider the action and will find its way into the news.

NAME
   order - Order a ship to auto-navigate

Level: Expert

SYNTAX
   [##:##]% order  [c|r|s|d|l]

You  use  the  order command to give sailing orders to ships.  At each update,
ships sailing under orders autonavigate toward a specific destination  sector.
Telegrams notify you of arrivals.

ONLY merchant ship may be given orders, but in order to move during the update
a ship must have at least one crew (which may be civilian or military, but not
an uncompensated worker).  Merchant ships are those that have 0 for their fir-
ing range and gun limit values.

Note that your ships sailing on orders will be interdicted just as if you were
navigating them by hand.

   [##:##] Command: order  c Clear Orders

     Use the clear option to wipe out any orders the ship currently has.  This
will remove all starting and ending points and clear all the cargo levels  for
the ship.

   [##:##] Command: order  s Suspend Orders

     If  you  want  to  keep orders but don't want the ship to move during the
update use the suspend option.  A quick look at 'sorder' will display the  eta
time  as  suspended.  As long as a ship is suspended it will be unable to move
during the update.

   [##:##] Command: order  r Resume Orders
     Resume will allow ships that have a suspended order to move again.

   [##:##] Command: order  d  [dest2|scuttle|-] Declare Orders

To declare an order you have 3 options.

        1) Order a ship to any sector on the map.
        When it arrives it will clear its orders.

        2) Order a ship to any sector, load goods,
           move to a second sector and unload goods.
           Continue to loop between the 2 points.

        3) Order a ship to any sector on the map.
           When it arrives, it will scuttle itself if it is in a harbor that
             is at least 2% efficient.  This is useful for tradeships.

   Example:  You have a cargo ship (#6) in your harbor at sector 6,0
   You want to move good between that harbor and another harbor at
   sector 14,0.

    order 6 d 6,0 14,0

   This reads:
    Cargo Ship #6, move to sector 6,0 load goods, sail to sector 14,0
    unload cargo then load again and sail back to 6,0.

   Example: You have a tradeship (#666) at sea in sector -10,0 and you
   want to move it to a friendly harbor at 20,4.

    order 666 d 20,4 -

   The ship will now move to sector 20,4 with the most efficient path.

   Example: You have a tradeship (#666) at sea in sector -10,0 and you
   want to move it to a friendly harbor at 20,4, and then scuttle itself.

    order 666 d 20,4 scuttle

   The ship will now move to sector 20,4 with the most efficient path,
   and scuttle itself when done.

   Note that only trade ships can be given auto-scuttle orders, and won't
   scuttle themselves at sea.

   [##:##] Command: order  l    

Set cargo Levels.

   Example: Cargo ship #109 is at your harbor in sector 10,0.
   You have agreed to trade 200 lcm and 100 hcm to your friend and
   he will give you 100 shells each update.  His harbor is at -10,2.
   Using 'order declare' you set up your start point 10,0 and end point -10,2

   order 109 l 1 start lcm   200
   order 109 l 2 start hcm   100
   order 109 l 1 end   shell 100

   When your finished the output would look like this.

   sorder 109
   shp #   type           x,y     start   end     len  eta
     109   cargo ship 2  10,0      10,0   -10,2    11   1

   qorder 109
   shp #   type           [Starting]  (Ending)
     109   cargo ship 2   [1-l:200 2-h:100 ] , (1-s:100 )

AutoNav Features.

Whenever a ship is autoloading cargo, it will always wait until  it  loads  to
capacity.   If a ship does not load fully it will not move!!!  Remember 'ships
need food!!' unless the NOFOOD option is enabled.  Set one of your cargo holds
to  load food or your ship will starve at sea.  When unloading cargo, the ship
will unload all goods listed in the cargo holds ONLY!  It will not unload  any
extra good manually placed on the ship.

If  you  are dealing with civilians 1 will be left in either the sector or the
harbor depending if your loading or unloading.  In either case when you arrive
at  the other harbor all but 1 civ will be dumped into the harbor.  Be careful
if you set civilians as one of your cargo levels.

If the FUEL option is enabled ships will try and fuel when they load cargo  in
the  starting  or  ending point and they currently have a fuel level less then
half of their max fuel level.  Auto fueling is not foolproof.  If you  declare
a long path and the ship does not pass through any harbors it might run out of
fuel and mobility. Remember ships can only autofuel in harbors.

You can set any commodity in the game to be loaded on the  ship.   However  if
you tell a ship to load a commodity it can not hold it will be ignored.  Exam-
ple:  If you tell a battleship to load Lcm, and of course  it  does  not  have
that  capability, see 'show ship capability' that level will be ignored at the
update.  Planes and Units are not commodities so they can not be  loaded  this
way.

At  update  time,  the most direct path from the ship to destination is calcu-
lated.  Each ship is then autonavigated along that path to  the  best  of  its
mobility.   The  path  is  calculated  from what the player knows of the world
(what you can see using the bmap command).  Open sea,  bridges,  harbors,  and
unexplored regions of the world are considered to be navigable.  Your friend's
harbors and bridges may be uses as long as the harbor >= 2% and the bridge  >=
60%.   Your  ships  will also try to avoid any mines you have declared on your
bmap.  'x' or 'X' characters.  Should your ship hit a mine the ship will  stop
moving  and  its  orders  suspended.  You bmap will also be updated with a 'x'
marking the sector for you.

If a ship sails in range of enemy forts they will be fired upon.  Setting your
ship  to  autonavigate  into an area with good fort cover could result in many
ships getting sunk fast.  However you could put an invasion  fleet  off  some-
one's coast in a hurry.

If  the  ship has a 'sweep' flag ships will try and sweep any mines if any are
present as they move.

Radar operates continuously as the  ship  moves  along  the  path,  constantly
adding sector information to the known world map.

The autonav code will try and use as much mobility as possible and this is all
done before mobility is gained from the update.  After an update has completed
your ship will have mobility so it can be moved by hand if needed.

Level: Expert

SYNTAX
   [##:##]% paradrop    route|destination

The paradrop command is used to sneak troops behind enemy lines, or to drop in
unawares on lightly-defended enemy islands or outposts.  It represents a  com-
plete mission for one or more transports and escorts taking off from one place
and returning to base at the end of the mission.

 represents a list of planes which can  carry  commodities.   Only
planes  which  have  a transport capacity, belong in a sector which is stocked
with gas and military, and  have  sufficient  mobility  will  be  successfully
selected  for  the  mission. Only planes with the para ability may be used for
paratroop missions.

 represent a list of fighter planes which are  capable  of  escorting
the  transports  all the way to the target.  To be selected, escorts must have
fuel and mobility.

 represents an assembly point, where all of the planes  in  the  mission
meet  before  proceeding  on to the target sector.  The assembly point must be
owned by you, and must not be more than four sectors  away  from  any  of  the
planes selected for the mission.

Route  is  a normal empire path specification. You may also give a destination
sector on the command line, or at any time while giving the route, and  empire
will use the best path from the current sector to the desired destination sec-
tor.

If the planes manage to fight through enemy air defenses and arrive on-target,
each  transport  in  the  mission  will  be shot at by any guns present on the
ground.  Surviving transports will drop the paratroops they carry, which  will
attack any enemy military occupying the target sector.

See  info  Attack for the exact procedure. The sector being air-assaulted will
have exactly the same reaction to being conquered as if it  were  attacked  by
land.

Note  that  a  plane  must  be  at least 40% efficient before it can leave the
ground.

NAME
   payoff - Find out the current payoff of a trade ship

Level: Expert

SYNTAX
   [##:##]% payoff [ | ]

The  payoff  command  gives a census of your trade ships, and lists the payoff
they would give if scuttled at the current sector.

The  and  arguments are provided in case you only  wish  to
look at one ship or one fleet or all ships within a given area.

Payoff  expects  an  argument.   To  see every trade ship you own, give it the
argument '*', or type "ship *".

The report format contains the following fields:

    shp#  the ship number
shiptype  the type of ship; patrol boat, submarine, etc,
     x,y  the ship's current location (relative to your capital),
      $$  the money you would get if you scuttled this ship

          For example:
             [##:##] Command: payoff *

                       shp#     ship type  orig x,y       x,y    dist $$

NAME
   pdump - Dump raw plane information

Level: Expert

SYNTAX
   [##:##]% pdump  []

The  pdump  command  displays  all  information on some or all of your planes.
pdump is a combination of  plane  and  pstat.   Each  plane's  information  is
printed on one very long line.  Fields are separated by a single space.

This command is designed to be used for input to an empire tool such as ve.

In  the  syntax of the pdump command  are the planes on which you wish
information, [] are the fields you wish to dump.   If  no  fields  are
specified, all fields are printed.  (see info Syntax).

A pdump command lists all selected planes headed by:

   Sun Feb  9 22:16:37 1997
   DUMP PLANES 855544597
   

The  first line is the date.  The second line is the "DUMP PLANES "
where the  field is the current timestamp.  The third line  is  the
columns which are output.

These columns represent the following fields which are also the selection cri-
teria for the command.

The following may be used as fields.  They must be entered  EXACTLY  as  shown
here (no partial pattern matching is done.)

      type     type of plane
      x        x location
      y        y location

      react    current reaction range
      range    maximum range
      load     load rating
      fuel     amount of fuel used in one flight
      hard     hardness
      ship     ship number the plane is on
      land     land unit number the plane is on
      laun     launchable?
      orb      orbiting synchronously?
      nuke     nuke name (if armed)
      grd      groundburst? (if armed)

A typical usage might be:
   [##:##] Command: pdump #5
which would list data for all planes in realm #5.

A pdump lists each of your planes in the specified area.  The header line is a
list of fields that correspond to the order that pdump prints the plane  info.

Also, if you give a ship # instead of coordinates or a realm,  map  will  show
you a small realm around the given ship (assuming you own it).

If  you use nmap, you can get a map that shows new sector designations instead
of old sector designations of your own country.

If you use lmap, you can get a map around a land unit, instead. Pmap does  the
same for a plane. Smap does the same for a ship.

MAP FLAGS

If you give an 's' flag, all your ships will be shown on the map.  An 'l' flag
does the same for land units, and a 'p' for planes.

SYNTAX

SYNTAX
   [##:##]% power new [num]

SYNTAX
   [##:##]% power country 

The  power report provides one view of national strengths.  It can be particu-
larly helpful in planning defense strategies and treaty voting.

If the optional num argument is given, only the top num entries in  the  power
chart  will  be displayed.  Note that for deities, if you give a negative num-
ber, only the top num entries in the power chart will be  displayed,  and  the
power number rating will not be displayed.

If  the  optional new argument is given, the program will take several minutes
to gather information and generate a power report  based  on  that  up-to-date
information.  This costs several BTU's (typically 10).

If  the  optional  new  argument  is not given, the program will shown you the
report generated the last time someone asked for new data.

If the optional country argument is given, then the information is only  given
for  those particular countries.  Countries are separated by the "/" character
as in:
   [##:##] Command: power c Fodder/19/Mirky
Note that countries may be specified as either names or numbers.

In the power report the countries are listed in order of decreasing power fac-
tor, each being represented by a line in the following format:

   sects  eff civ  mil  shell gun pet  iron dust oil  pln ship unit money

Each  column represents a different commodity or aspect for that country.  The
columns and values used in computing the power factor are:

   a    # of sectors
   b    average sector efficiency
   c    # of civilians
   d    # of military
   e    # of shells
   f    # of guns
   h    tons of iron ore (not displayed)
   i    tons of gold dust
   j    # of gold bars
   k    tons of food (not displayed)
   l    tanks of oil
   g    # of planes
   m    # of ships
   mm   tons of ships (not displayed)
   r    # of land units
   n    # of dollars
   oo   units of light construction materials (not displayed)
   pp   units of heavy construction materials (not displayed)
   qq   megatons of nuclear weaponry (not displayed)
   bb   gold bars

The power factor is determined by the following equation:

   power factor = n / 100
                  + (c + d + e + h + i + k + l + mm + oo) / 10
                  + pp / 5
                  + (f + a * b) / 3
                  + g + m + j + r
                  + a * 3
                  + qq * 100

However, if the NEWPOWER option is in effect, the formula becomes:

   power factor = for each land unit calculate and add the following
                   ((((land unit lcm cost / 10) * (land unit effic / 100)) +
                     ((land unit hcm cost / 10) * (land unit effic / 100))) * 2)
   power factor += for each ship calculate and add the following:
                   ((((ship lcm cost / 10) * (ship effic / 100)) +
                     ((ship hcm cost / 10) * (ship effic / 100))) * 2)
   power factor += for each plane calculate and add the following:
                   (20 * (plane effic / 100) * (nation tech level / 500))
   power factor += ((nation money / 100) + (petrol / 500) +
                    ((civilians + military) / 10) + (shells / 12.5) +
                    (iron / 100) + (dust / 5) + (oil / 10) + bars +
                    (guns / 2.5) + (lcms / 10) + (hcms / 5))
   power factor += ((number of sectors * (average sector effic / 100)) * 10)
   power factor = ((power factor) * (nation tech level / 500))
   power factor = ((power factor) * (research factor))

The research factor is either 1, if RES_POP is not being used, or  1+(max  pop
in a sector)/10000, if it is being used.

NAME
   pray - Interacting with the Deity

Level: Basic

There  is  one  country  in the game that has no material possessions yet owns
everything...  That country is country #0 (often called The Deity).  The power
of  this  ethereal  country is unbounded -- it can do anything from creating a
civilian (as was the case with the first civilian), to literally moving  moun-
tains.

Despite this great power The Deity keeps his hands out of the game and country
#0 only gets involved when there is a problem with the source code, or prohib-
ited  activity  is suspected.  The most common form of prayer is the telegram;
if you should be in need of aid type:

   [##:##] Command: pray

When the program requests your message for The Deity, state it simply:

   Enter telegram for your Gracious Deity; end with ^D
   <512> I can't do anything!!!!
   <488> HELP!!
   <481> .

If this doesn't get helpful results then you should send a second prayer  with
more specific details. e.g.

   <512> Every time I type any command which requires a BTU
   <461> I get dumped out of the game.  Can you help me?
   <413> .

This last message is sure to move the compassionate Deity to provide help.

In  general,  when you encounter problems, be as specific about them as possi-
ble. Include a transcript of the output of the problem, if available. The more
information  you provide, the easier it is for the deity to give you a quick &
fair fix for the problem.

   production - Predicts production of sectors at the next update

Level: Basic

SYNTAX
   [##:##]% production 

Produce predicts how much is going to be produced at the next update.  It also
shows you how much could be produced if more materials were available  in  the
sector.

Note  that  due  to random rounding factors in the update, prod is not totally
accurate -- it may be off by a little bit.

In the syntax of the produce command  is the area  on  which  you  wish
information, (see info syntax).  Produce reports on any sector that would pro-
duce goods, sectors that don't produce anything or are less than 60% efficient
are ignored.

A typical usage might be:
   [##:##] Command: produce 0:9,0:9 ?type=m
which would list data for mines in an area to the south-east of the capital.

The production report is headed by the lines:

   PRODUCTION SIMULATION
    sect  des eff wkfc will make--- p.e. cost use1 use2 use3  max1 max2 max3   max

These columns represent:

        sect  the x and y coordinates of the sector
         des  The sectors designation
         eff  the  efficiency of the sector in doing its task.  Note that some

        p.e.  Production efficiency - the efficiency with which the product is
              made (i.e. how much benefit education or technology gives).
        cost  The cost of the product in dollars
    use[123]  The  three use fields show how much of what product are consumed
              in producing the given number of products produced.
    max[123]  The three max fields show what would be used if it  were  avail-
              able  in  the sector (i.e. this is what the workforce is capable
              of using if it was available).
         max  This field gives the maximum output for the workforce if all the
              raw materials were present.

Level: Basic

SYNTAX
   [##:##]% pstat [ | ]

The  pstat  command  is  a report of the varying statistics of your planes and
lists the info in a readable format.  Since your planes'  statistics  vary  by
tech  level,  this  is a very useful way to see what the attack, defense, etc.
modifiers are on a per-plane basis.

The  and  arguments are provided in case you only wish  to  look
at one plane or all planes within a given area.

pstat  expects  some  argument.   To  see all planes, use the argument '*', or
enter "pstat *".

NAME
   radar - Perform radar scan from ship or sector

Level: Basic

SYNTAX
   [##:##]% radar [ | ]

The  radar command bears some resemblance to modern high-resolution radar.  It
has a circular range dependent upon its efficiency.

To run land radar type:
   [##:##] Command: radar 
where  must be the sector where the radar station resides, or  an  area
that contains one or more radar stations.

The program will respond with the station's efficiency and range and then dis-
play the area.

What is displayed is dependent upon the range.  Sectors and ships  within  1/3
of the range are displayed with their sector or ship designations.  Sectors at
greater distances are indicated by a '?'  if they  are  inhabited  by  another
country.

A  100% radar station in a country with infinite technology on a clear day has
a range of 16.  The range is linearly related to efficiency; thus a 50%  radar
station  can see half as far as a 100% radar station.  The range is related to
technology level in the usual way, i.e., it varies  linearly  with  technology
factor  as indicated in the nation report; see info nation and info technology
for details.

Satellites will appear on the map as a '$'.

WARNING!  Land radar cannot spot submarines.

FURTHER WARNING!  Even worse, should your cunning enemy move troops  right  to
your doorstep and leave the sector designated a wilderness it would show up on
your very efficient radar as '-'.  Thus you would never know he was  there....
Well, almost never.

To run unit radar type:
   [##:##] Command: lradar 
where  is the number of a unit or an army designation.

To run naval radar type:
   [##:##] Command: radar 
where  is the number of a ship or a fleet designation.

Sea  radar  is  highly dependent upon what kind of ship you have and what kind
the opponent has.  (e.g., Battleships can see battleships far away but fishing
boats must be close together to see each other).

The  maximum  distance at which ship A can see ship B is dependent on two fac-
tors: the spying ability of ship A, and the visibility of ship B.  Battleships
have  sophisticated  communications equipment which give them a maximum spying
range of 6 while fishing boats, having little such equipment, have  a  maximum
range  of  2.   This  factor  is shown in a table in info Ship-types under the
heading spy.  On the other hand, the ships vary in size and consequently, vary
in  visibility.   Battleships,  oil  derricks, and carriers are the easiest to
see; next come cargo ships, heavy cruisers and tenders, and so on.   See  info
Ship-types for a chart.

Ship A will see ship B if the distance between them is less than:

                spy factor of ship A * visibility of ship B
   efficiency * ------------------------------------------- * technology factor
                                  20

Note  that, although subs can not be found via radar, destroyers automatically
use sonar so they can see subs.  Destroyer A will see submarine B if the  dis-
tance between them is less than:

                spy factor of ship A * visibility of ship B
   efficiency * ------------------------------------------- * technology factor
                                  20

NAME
   range - Edit the range of a plane

Level: Expert

SYNTAX
   [##:##]% range  

The  range  command  is  used to limit the maximum range of individual planes.
This can be useful in setting up high tech interceptors (planes,  ABMs,  SAMs,
etc.) to cover only a small limited area.

Note  that  missiles  always fly at double range (since they don't need to fly
back), so you should cut the desired range in half before using the range com-
mand.

For  example,  if  plane  1  were a plane and you wanted to limit its reaction
radius to 6, then you would type:
   [##:##] Command: range 1 6
and if plane 2 were a missile and you wanted to limit its reaction  radius  to
6, then you would type:
   [##:##] Command: range 2 3

Level: Basic

SYNTAX
   [##:##]% read

The read command is used to read the telegrams sent you by other countries and
by the game, (e.g. when you make a sale or are attacked).

When telegrams arrive you are informed with:

   You have a new telegram waiting ...   if there is just one new one, or
   You have ten new telegrams waiting ...   if there are ten of them, or
   You have several new telegrams waiting ...   if there are very many.

After reading all your telegrams you may discard them by answering yes to  the
question  posed.   If  you answer no the telegrams will remain pending but you
will not be reminded of them.

This command reads only telegrams & bulletins, use the 'wire' command to  read
announcements.

NAME

Level: Expert

SYNTAX
   [##:##]% recon    route|destination

The  recon  command  is used to gather intelligence about sectors that the spy
mission overflies.  The planes take off from their respective airports, assem-
ble, and then fly the mission and land in the destination sector.

  represents a list of planes which are to be performing the intel-
ligence gathering operation.  Only planes which are  provided  with  gas,  and
have sufficient mobility will be successfully selected for the mission.

  represent  a  list of fighter planes which are capable of escorting
the transports all the way to the target.  To be selected, escorts  must  have
fuel and mobility.

  represents  an  assembly point, where all of the planes in the mission
meet before proceeding on to the target sector.  The assembly  point  must  be
owned  by  you,  and  must  not be more than four sectors away from any of the
planes selected for the mission.

Route is a normal empire path specification. You may also give  a  destination
sector  on the command line, or at any time while giving the route, and empire
will use the best path from the current sector to the desired destination sec-
tor.

When  getting  a  path interactively, empire will show you the information you
have (from your bmap) concerning the current area, to help plot your course.

Information given by recon is not totally accurate.

Recon missions can be intercepted just like any other mission.  If the  desti-
nation  sector  is  not  an  airport, then all planes in the mission must have
V/STOL capability.

Planes with the ASW ability will perform a sonar search on each sector as they
fly  through it.  Each sub contact will be reported only once, giving the sec-
tor and number of the sub, from the sector  in  which  it  is  first  detected
(which  may not be the sector the sub is in, as plane sonar has a range depen-
dent  on  acc,  and  a  chance  of  finding   a   sub   of   ((100-acc)-(4-sub
visib)*10))+((100-effic)/5)  percent.   The  sub  being sonared may detect the
sonar ping.

Note that a plane must be at least 40%  efficient  before  it  can  leave  the
ground.

        3) MGM               Hostile   At War

Relations are: Allied, Friendly, Neutral, Hostile, Mobilizing, Sitzkrieg,  and
At War. Each has certain ramifications.

Allied  Your  ally is someone you trust deeply, and are willing to make sacri-
fices for.  If you are allied with someone, then your forts, ships, planes,  &
artillery  will  support them in battle.  Also, they can over-fly you, and you
will not be told.  (I.e. an ally can map you out easily).  When  you  use  the
"wall"  command,  it  sends  a  flash  message to all of your allies (see info
wall).  If the ALL_BLEED option is in effect, then you will benefit from  tech
produced  by your allies.  Allied nations are assumed to have "friendly" trade
relations.

Friendly  When you accept a country as a trustworthy trading partner, then you
establish  friendly  relations  towards  them.  This allows them to sail ships
into your harbours, load and unload goods, fuel, and have their ships repaired
there.   You  are  allowed  to  "tend"  and  "follow" friendly ships.  You are
allowed to cede sectors to a friendly nation, and may send them  "flash"  mes-
sages  (see  info  flash).   You will be warned, however, if they overfly your
territory.  And if they do it enough times, your diplomatic relations  towards
them  will  be  automatically  downgraded.  You may "spy" on a friendly nation
with no consequences.

Neutral  You start out neutral towards all countries.  It  simply  means  that
you  are ambivalent towards them.  If they overfly your territory, you will be
warned and your relations will automatically downgrade.  Caught spies will  be
deported.

Hostile  If  you  are  suspicious that a nation may be planning to attack you,
but you are not committed to an all out war  against  them,  then  you  should
declare  hostile  relations  towards  them.  This will ensure that your planes
will intercept theirs if they try to over-fly you, and your forts will fire on
their  ships when they sail within range.    Also, your a-sat's and abm's will
attempt to intercept their satellites and missiles independent of  the  target
sector they have launched them at, and your ships with anti-missile capability
will attempt to intercept any incoming marine missiles within  range.   Caught
spies will be shot.

War  If  you are committed to expending major resources against a nation, then
you should declare war on them.  This will cause all of your ships, artillery,
planes  and  missiles which have been put on a mission to react to enemy move-
ment.

The following paragraphs apply only if the SLOW_WAR option is used.

Mobilizing  If you are Mobilizing, it means that you have  declared  war,  and
are  getting  ready  to attack. You cannot attack someone's land until you are
actually At War. At the next update, you will automatically move to Sitzkrieg.
Your interdiction of the enemy will be the same as if you were hostile towards
them.

Sitzkrieg  Sitzkrieg is the same as Mobilizing. You still are unable to attack
their land. At the next update, you will automatically move to At War

When you are At War with someone, you may attack them willy-nilly.

Note  that  if  the  SNEAK_ATTACK option is enabled, you can make an attack on
someone you're not at war with (not shelling or anything else, just an  attack
or  assault).  For  this  privilege,  you are charged $5K. Once your attack is
over, whether successful or not, you automatically declare  war  on  them  and
must  wait  through  the  normal SLOW_WAR procedure to attack again.  (In this
case, the $1K fee for declaring war is waived)

Also, there is an automatic  progression.  If  someone  you  are  allied  with
attacks  you,  you  become hostile towards them. If someone you are neutral to
over-flies or attacks you, you become hostile towards them. Neither  of  these
progressions can lead to war, however, they both stop at hostility.

The repay command is used to repay loans from other countries.

The    argument  is  the  number of the loan you are repaying and if not
included on the command line it will be solicited by the program.

You can repay all or part of the loan with this  command;  however  beware  of
letting  the  loan become overdue -- the lender may decide to force collection
(see info collect).

When you repay on a loan a telegram is sent to the lender informing her/him of
the amount repaid.

   This is how the ranges are determined.
   (1) If your value of the statistic is 0, then n/a (not applicable)
       will be printed in that column.

   (2) If the value for both countries is > 100, then shift them down so
       the lowest one is at 100.

   (3) Each of the following tests is made in order.  As soon as one of them
       is true, then  that will be the range for that statistic:
         2.0 * yours < theirs
         1.5 * yours < theirs < 2.0 * yours
         1.2 * yours < theirs < 1.5 * yours
         1.1 * yours < theirs < 1.2 * yours
         yours / 1.1 < theirs < 1.1 * yours
         yours / 1.2 < theirs < yours / 1.1
         yours / 1.5 < theirs < yours / 1.2
         yours / 2.0 < theirs < yours / 1.5
                       theirs < yours / 2.0

   (4) Once the range has been determined, it is shifted back up to where
       it should be.

   (5) There is a "minimum range" for the different characteristics:
         tech: 20
         res:  10
         edu:   5
         hap:   5
       If the distance between the high and low end of the range is smaller
       than the "minimum range", then the range is expanded (equally in both
       directions but never crossing zero) to be equal to the minimum range.
       However, it will never be expanded beyond twice your value of that
       statistic.

NAME
   retreat - Set retreat conditions/paths for ships or fleets

Level: Expert

SYNTAX
   [##:##]% retreat [ | ] [] []

SYNTAX
   [##:##]% lretreat [ | ] [] []

The retreat command allows you to examine or modify the retreat paths and con-
ditions of your ships or units. The following description is for  ships.  Land
units  are  exactly the same, except of course that some of the retreat condi-
tions (being sonared, depth charged, etc) don't apply.

The  and  arguments are provided to specify which ships  to
view  or  give  orders  for.  If  a fleet designation is given when specifying
orders, the orders apply to all ships within that fleet.

Retreat expects an argument.  To see every ship you own, give it the  argument
'*', or type "retreat *".

The report format contains the following fields:

    shp#  the ship number
shiptype  the type of ship; patrol boat, submarine, etc,
     x,y  the ship's current location (relative to your capital),
     flt  the fleet designation letter (set by fleetadd command),
    path  the ship's current retreat path.
 as_flt?  whether or not the ship's retreat path is a fleet retreat path
   flags  what conditions the ship will retreat under

For example:
   [##:##] Command: retreat *

   shp#     ship type       x,y   fl path       as flt? flags
      0 battleship 4        2,0      jjuuj              I
   1 ship

Overview

A player may give retreat orders for a ship or a fleet. Retreat orders include
a set of conditions that determine when the fleet/ship  will  retreat,  and  a
path that the fleet/ship will follow. When a condition is met for a particular
ship, the as flt? field is checked. If it is Yes,  then  every  ship  in  that
fleet  with  fleet  retreat orders retreats along the specified path. If it is
no, then the retreat orders apply to  that  ship  only,  and  only  that  ship
retreats.

When a ship is added to a fleet, it is given the retreat orders of that fleet,
if any exist.

Retreat orders are wiped when a ship navigates.

Retreat conditions at present include:

          Condition Meaning
          I         Retreat when the ship is injured,
                    i.e. whenever the ship is damaged
                    by fire, bombs, or torping.
          T         Retreat when a sub torpedos or tries
                    to torpedo the ship.
          B         Retreat when a plane bombs or tries
                    to bomb the ship.
          S         Retreat when the ship detects a sonar
                    ping.
          D         Retreat when the ship is depth-charged.
          H         Retreat when helpless. A ship is helpless
                    when it is fired upon, and no friendly
                    ships/sectors (including the ship itself)
                    are able to fire back at the aggressor.
                U               Retreat upon a failed boarding attempt.
          C         Clear the flags

For example, if the battleship above was fired at, it would attempt to retreat
2  sectors,  jj,  using the normal amount of mobility for moving 2 sectors. It
would then look like:

   shp#     ship type       x,y   fl path       as flt? flags
      0 battleship 4        2,0      uuj                I

NAME
   sail - Give sailing orders to a ship

Level: Expert

SYNTAX
   [##:##]% sail  [|q[uery]|-]

You  use  the  sail  command to give a sailing path to ships.  At each update,
ships with a sailing path autonavigate along the path that was set  for  them.
Telegrams  notify  you of arrivals or problems encountered while attempting to
follow the path.

Radar operates continuously as the  ship  moves  along  the  path,  constantly
adding sector information to the known world map.

Ship  movement  is  performed before mobility is increased.  This insures that
after the update, ships with a sailing path will still have some  mobility  so
that you can always manually navigate to some extent.

Note  that  ships sailing can encounter exactly the same interdiction as ships
navigating.

   [##:##] Command: sail  q[uery]

sail, with the query parameter, shows the current sailing  path.   The  report
indicates:

        shp#          ship number
        ship type     type of ship (cargo ship, destroyer, etc)
        x,y           ship's current position

   4 ship(s)

   [##:##] Command: sail  -

sail, with the - parameter, causes the sailing path for the ships specified to
be removed.

The PATH is a normal empire path specification. You may *not* give a  destina-
tion  sector  on the command line, or at any time while giving the route.  Use
the order command if you wish this functionality.

When getting a path interactively, empire will show you  the  information  you
have  (from  your  bmap)  concerning  the  current area, to help you plot your
course.

NAME
   satellite - Download data from a reconnaissance satellite

Level: Expert

SYNTAX
   [##:##]% satellite  [ [?cond&cond&...]]

The  satellite  command  is  how  you get information from your satellites.  A
satellite must be in orbit (launched) before it will begin transmitting.   The
type of information you get from a satellite depends on what type of satellite
it is.

An ordinary satellite will return data that looks remarkably like  radar  out-
put.  If the satellite has imaging capabilities you will see the sector desig-
nations.  If not then you will see a '?' for inhabited sectors.

A satellite with imaging capabilities will also show ships and land units.

Spy satellites provide much more information.  Their output is  a  table  that
looks  remarkably  like  spy  output followed by another table listing all the
ships in the area with their owner, ship type, and efficiency.

Spy satellites with imaging capabilities can also see subs!

After launching, a satellite will take a while to come on line.   During  this
period, (shown by mobility being < 127), you cannot use the satellite.

If a satellite has been damaged, then it will only transmit partial data.  For
example, a 75% satellite will only display three out of  every  four  sectors.
Note  that it will always be the same 75% of sectors which are displayed (i.e.
it is not random), so you will gain nothing  by  repeatedly  downloading  data
from the satellite.

You  may also filter the information you receive from the satellite using con-
ditionals.  Here are some examples to show you how conditionals work.  In  all
of the following examples, we will assume that we are using satellite #28.

To list all airports:
   [##:##] Command: sat 28 se ?des=*
To list all airports owned by country #7:
   [##:##] Command: sat 28 se ?des=*&own=7
To list all ships in 12,14:
   [##:##] Command: sat 28 sh ?xloc=12&yloc=14
To list all land units: To list all cavalry units:
   [##:##] Command: sat 28 l ?type=cavalry .

For  a  complete list of conditionals you can use, see info Syntax.  Note that
the large radar map is only drawn when the output is not filtered:

NAME
   scrap - Scrap a ship, plane, or unit

Level: Basic

SYNTAX
   [##:##]% scrap  

This  command  allows  you to scrap planes/units/ships when you no longer need
them.

Ships may only be scrapped friendly 60% harbours.  Planes may only be scrapped
in 60% airfields.  Units may be scrapped in any sector.

When  scrapping  a unit, plane or ship, you receive materials equal to 2/3 the
amount used to build it. The materials are put in the sector where the  scrap-
ping occurs.

When  scrapping  a unit, you also get the military that the unit represents as
mil in the sector. (Example: a unit that takes 100 mil to build is at 50%, and
is  scrapped.  50  mil  will  be added to the sector) Units on ships cannot be
scrapped.

If you scrap a ship or unit that has planes  on  board,  the  planes  will  be
transferred to the sector.

Planes, units, and ships may be scuttled in any sector.

If you scuttle a ship or unit that has planes on board, the planes will either
be transferred to land (if a unit, or if the ship is in a harbor), or will die
(if the ship is elsewhere)

Units on ships may not be scuttled.

Scuttling trade-ships (if the TRADESHIPS option is enabled) has other effects.

The  sdump  command  displays  all  information  on some or all of your ships.
sdump is a combination of ship, cargo, and sstat.  Each ship's information  is
printed on one very long line.  Fields are separated by a single space.

This command is designed to be used for input to an empire tool such as ve.

In  the  syntax  of  the sdump command  are the ships on which you wish
information, [] are the fields you wish to dump.   If  no  fields  are
specified, all fields are printed.  (see info Syntax).

An sdump command lists all selected ships headed by:

   DUMP SHIPS 855544597
   

The  first  line is the date.  The second line is the "DUMP SHIPS "
where the  field is the current timestamp.  The third line  is  the
columns which are output.

These columns represent the following fields which are also the selection cri-
teria for the command.

The following may be used as fields.  They must be entered  EXACTLY  as  shown

NAME
   sell - Sell commodities on the world market

Level: Expert

SYNTAX
   [##:##]% sell    

The  sell  command allows nations to sell commodities on the open market.  Not
all commodities can be traded -- notably civilians and military.

The  is the type of commodity you are selling,    represents
the range of sectors which will be selling items.  Only harbors and warehouses
which are at least 60% efficient may sell goods.

, if positive, reflects the amount of food to be taken from each  sec-
tor.   If  negative,  the  amount shows the lower limit of food required to be
present in that sector and will only  sell  food  in  excess  of  that  limit.
 is the base price of the commodity per unit to the world.

In  addition,  the  sector  selling  needs to have at least 1 mobility to sell
goods.

Typical output looks like:

   [7:640] Command : sell food 4,-2 10 5
   Sold 10 food at 4,-2 (206 left)

   [7:639] Command : sell food 4,-2 -100 5
   Sold 106 food at 4,-2 (100 left)

Only harbors and warehouses may sell items.  Also, note that due to  the  time
delay market, you don't get any money until the goods are actually bidded upon
and paid for once the bidding time is up.

There is a certain overhead on selling items, based on the difficulty of  mov-
ing  the  items in question.  This is based on the tax you pay which is set by
the deity (see info version).

NAME
   sharebmap - Share parts of your bmap with another country

Level: Expert

SYNTAX
   [##:##]% sharebmap   []

This  command  will share all of the information on your bmap with the country
.  In order for it to work, they must be friendly towards you  and
your  bmaps  must  already  overlap  to some extent.  Note that your 'working'
bmaps are not compared for this, but rather your 'true' bmaps.  In particular,
you  can not fool the game into thinking that your bmaps overlap through using
the 'bdes' command.  See the bottom of 'info bmap' for an explanation  of  the
difference between your 'working' and your 'true' bmap.

When  sectors owned by you get transferred to your friend's bmap, they will be
replaced with the first letter of your country name  (capitalized),  the  only
exception  being  harbors and bridges which will always be transmitted.  Also,
if you want to send them the location of owned sectors having a certain desig-
nation you can specify that using the optional  argument.  For example if
your country name was "TheScum" and you typed:
   [##:##] Command: sharebmap Fodderland #1 j
then all of your bmap would be added to Fodderland's bmap, with sectors  owned
by  you  replaced  with  'T',  except for your '=', 'h', and 'j' sectors which
would be sent as is.

Note that the destination bmap will only be changed if in that location  there
was  a  '?',  a '.', a ' ', or the first letter of your country name (capital-
ized).  Thus, the receiving country will not loose  any  information  in  this
exchange.

Note  that  the  sharebmap command only changes your 'working' bmap and so you
can delete sharebmap information from your bmap by typing:
   [##:##] Command: bmap revert

The  shoot  command allows you to shoot enemy civilians or recalcitrant uncom-
pensated workers.  In order to be able to  keep  the  populace  under  control
(i.e.,  not  have them rebel), you must have one military for every ten civil-
ians.  Any land units in the sector count towards the mil necessary  for  con-
trol.  Also, security units in the sector will make shooting more efficient,

Each civ or uw shot uses mobility (see info Mobility for the exact formula).

Fractions  are  rounded randomly up or down, depending on size. For example, a
0.8 cost has an 80% chance of being 1, and a 20% chance of being 0.

 is a positive number that is the number of people shot per sector.

After the program has collected any necessary information it  will  list  each
sector  where  your  troops shoot down the poor helpless people along with the
number of people murdered.

If all the civilians in the sector are removed, and it was a conquered sector,
it  will become completely controlled by you, and you will be notified of this
fact.

Having security troops in the sector will increase the efficiency of the  fir-
ing squads, resulting in more dead than you asked for. (They're enthusiastic)

Unless the unit is a bridge, a further parameter is needed to indicate whether
you  wish  information about construction of units, the statistics of units or
the capabilities & abilities of units.  So, for example
   [##:##] Command: show nuke capabilities
will give something like

type out a 11 by 13 sector map and also put the map in the file called mapfil.

If you use nmap, you can get a map that shows new sector designations  instead
of old sector designations of your own country.

Also,  if  you  give a ship # instead of coordinates or a realm, map will show
you a small realm around the given ship (assuming you own it).

If you use lmap, you can get a map around a land unit, instead. Pmap does  the
same for a plane. Smap does the same for a ship.

MAP FLAGS

If you give an 's' flag, all your ships will be shown on the map.  An 'l' flag
does the same for land units, and a 'p' for planes.

NAME
   sonar - Use sonar to look for ships

Level: Basic

SYNTAX
   [##:##]% sonar  

The  sonar  command allows ships to look for submarines and submarines to look
for ships.

If the  argument is specified then the sonar map will  not  be  drawn.
This  is  useful  if  you  just  need to see the list of ships you can detect.
Whether or not a map is printed, the sonar information will be added  to  your
bmap.

Only ships at sea may use sonar and sonar only detects ships which are at sea.
Furthermore, there must be a straight line of water between the  detector  and
the detected (sonar doesn't work around corners).

In the current implementation, sonar works similar to lookout.  The major dif-
ference is that a submarines cannot use lookout  to  sight  ships.   Likewise,
submarines cannot be sighted by ships via lookout.

There are two aspects to sonar - passive and active sonar.

ACTIVE SONAR

This  is the most visible form of sonar.  It is simply a ship's ability to use
sonar pings to detect other ships.  The range of  a  ship's  active  sonar  is
identical  to  the range that it can sight ships via lookout.  (see info look-
out) When you type "sonar 25", you are using active sonar.

PASSIVE SONAR

This is more subtle.  Passive sonar is a ship's ability to hear sounds, mainly
active  sonar  pings.  When a ship pings you with active sonar, you can detect
that ping.  If a ship with sonar gets pinged, that country receives a telegram
saying   "Sonar   ping   from  x,y  detected  by  ship  Z!"   In  its  current
implementation, passive sonar is the ability to detect a ping.

When a ship emits a ping, that ping has  to  travel  out  to  a  target  ship,
reflect  off  of  it, and then return to its source.  So, in order to detect a
ship X sectors away, a sonar ping must be able to travel 2X sectors - from the
source  to  the  target, and back to the source.  So, if a ship can use active
sonar to detect ships X sectors away, passive sonar can detect  active  sonars
from  2X  sectors  away.   So the range at which you can detect sonar pings is
twice the range at which you can use sonar.

The active and passive sonar modes means that you want to be careful when  you
use sonar, because you will tell others where you are long before you actually
detect them.  This also gives you some warning before you get  your  submarine
attacked,  as enemy ships have to use sonar to find you.  The key to submarine
warfare is "run silent", meaning use your sonar only when you have to.

On the other hand, destroyers are designed to hunt subs.  A destroyer guarding
a player's coast should use sonar often, especially if it has other destroyers
nearby to support him if he gets in trouble.

For example:
   [##:##] Command: sonar 3

   sb2 submarine 2 (#3) at 24,0 efficiency 76%, max range 2
   Sonar detects TheBorg (#5) bb4 battleship 4 (#1) @ 23,-1
     .
    . B ?
    . . .
     . . .

Sonar-capable ships of tech 310 or better can also  detect  mines  with  their
sonar,  although at only half their normal sonar range.  Mines will show up on
the sonar map as 'X' and this 'X' will be added to your bmap.

In the case of using sonar to detect subs, detection = (sub visibility +  ship
spy  value).   If detection is less than 8, then the sonar will just print you
something like:

     Sonar detects sub #12

If detection is above 7, then you will be told the ship type,  and  if  it  is
above 9, you will also be told the owner of the sub.  Note that type and owner
will always be shown for Friendly subs.

                            Concept : plane-sonar

Planes with the ASW ability can use sonar while on recon  missions.  See  info
recon for more details.

NAME
   spy - Snoop on adjacent enemy sectors

Level: Basic

SYNTAX
   [##:##]% spy 

The  spy command allows reconnaissance operations to enforce an oral treaty or
as preparation for an attack (or even for a prayer to the Deity).

The spy report will reveal, (in round figures), the numbers of troops,  civil-
ians, guns, shells, iron, and planes and the sector designation and efficiency
in neighboring sectors.

The sectors denoted by  are those from which you are spying, (see  info
syntax for format).  Note: you can only spy from sectors that have military or
land units in them.

Note that the number of BTU's consumed is dependent upon the number of sectors
into which you spy, e.g., a 5x8 area costs one full BTU.

If  you  are  spying  on  an unallied country your spy could be apprehended...
his/her chances are dependent upon the number of patrolling  military  in  the
sector.

However,  having  a  recon  unit in the sector the spy is coming from enhances
your chances of succeeding even if the spy is caught.

If the other country has declared itself at war with you the spy will be  shot
and  the other country, (and the rest of the world, through the news), will be
warned that you tried to spy on him...

If the other country is neutral towards you the spy will be deported.

Spies will also report all non-owned planes and land units that exist  in  the
sector  you  are spying from, such as allied land units that have been marched
there, allied planes that have been landed there, spy units that have  marched
there and non-allied units that have been trapped there.

Note  that  spy units are not always seen.  There is a 10-100% chance of a spy
unit being seen by the spy command.  See "info Spies" for more information.

NOTE

Spies reporting on the tech level of enemy units are pretty inaccurate.   They
can vary by +/- 20 tech or so...

NAME
   sstat - Report statistics of ship, fleet or ships in a given area

Level: Basic

SYNTAX
   [##:##]% sstat [ | ]

The  sstat  command  is  a  report of the varying statistics of your ships and
lists the info in a readable format.  Since your  ships'  statistics  vary  by
tech  level,  this  is a very useful way to see what the attack, defense, etc.
modifiers are on a per-ship basis.

The  and  arguments are provided in case you only  wish  to
look at one ship or one fleet or all ships within a given area.

Sstat  expects  an  argument.  To see every ship you own, give it the argument
'*', or type "sstat *".

The report format contains the following fields:

    shp#  the ship number
ship-type  the type of ship; patrol boat, submarine, etc,
     x,y  the ship's current location (relative to your capital),
     eff  the ship's efficiency,
    tech  the tech level of the ship
     def  the armor value of the ship (i.e. how strong is the hull)
     spd  the speed of the ship
     vis  the visibility of the ship (i.e. how easy is it to see)
     rng  twice the distance the guns can fire, The range formula is (rng/2) *
          ((tech + 50) / (tech + 200))
     fir  the number of guns the ship can fire at once

For example:

   [##:##]% starvation [|l |s ]

The  starvation command warns you of possible starvation in your sectors, land
units, and ships.

SYNTAX
   [##:##]% starv

With no arguments, the starvation command will list all of your sectors,  land
units, and ships that will starve at the update.

SYNTAX
   [##:##]% starv 

With  this syntax, the starvation command displays all sectors in  that
currently do not have enough food. It does not  take  into  account  emergency
food  growing & supplying (see info supply) It also does not worry about feed-
ing babies... it merely check for starvation. If you want population increase,
you'll need to chuck in some extra food...

SYNTAX
   [##:##]% starv l 

With  this  syntax,  the  starvation command will list which of your units are
currently not carrying enough food (see "info lload" and "info supply").   For
example:
   [##:##] Command: starv l *

   Mon Aug 28 04:53:05 1995

   2 units

SYNTAX
   [##:##]% starv s 

With  this  syntax,  the  starvation command will list which of your ships are
currently not carrying enough food to feed the people on them.  For example:
   [##:##] Command: starv s * ?type=frigate

   Mon Aug 28 04:53:29 1995
   Starvation

NAME
   supply - Cause a unit to draw supplies

Level: Basic

SYNTAX
   [##:##]% supply 

The  supply  command  causes  a  unit  to draw enough supplies from its supply
sources to make sure that it has its basic load of supplies.  Supply tells you
which units have enough supplies.

A basic load of supplies for a unit consists of:
     1) enough food to eat for one update

     2) enough shells to fire once
          A unit uses shells equal to its ammo stat to fire once.
          Use the show command to find out how much ammo
          the unit uses per shot.

     3) petrol equal to its fuel use number, if the unit uses fuel
          (show land stats will show the fuel use number)

If  the  unit has enough of all these things, it is said to be 'in supply'.  A
lack of any of these things is enough to make the unit 'out of supply'.

When supplies are drawn & used

A unit that fights may use a basic load of supplies to attack with.   (depend-
ing  on  the intensity of combat. The more intense the combat, the more chance
the unit will use a basic load of supplies)

During the update, each unit will attempt to draw food  supplies  just  before
starvation is calculated.

When  a  unit needs to draw supplies, such as when you use the supply command,
or the unit wishes to attack, or is attacked, etc, it must attempt to get them
from  supply  sources.  Other  things may use the same routines, such as loyal
sectors, which will draw food from supply sources when in  danger  of  starva-
tion,  and  ships/forts/sectors, which will draw shells when they need them to
fire defensively or fire AA at planes.

Supply Sources

There are four sources of supply. In each case, the unit must be within supply
range of the source. Supply range is:

   10 * ((tech+50)/(tech+200) sectors.

In  addition there must be a valid supply path to the source. A supply path is
a path of sectors owned by the owner of the unit  that  leads  to  the  supply
source.  (Note  that  the  path  may be of any length.. only the supply source
itself must be within supply range.. this is to make the coding  simpler,  and
may  change  in  the  future) The best path (in terms of mobility use) will be
used.

In each case, mobility is used to move the supplies.

The first source of supply checked is the sector the unit is in.  This is for-
aging, and uses some mobility from the unit itself.

If  the unit's needs can't be satisfied by forging, it look for an owned ware-
house or headquarters that is at  least  60%  efficient.  Drawing  from  these
sources uses mobility from the warehouse or headquarters. (A headquarters will
NOT supply a unit if it has no distribution path)

If still in need, the unit will look for an owned supply ship  (one  that  has
the  supply ability) in an owned harbor.  The harbor must be at least 2% effi-
cient. This uses mobility from the harbor.

If it still can't find enough supplies, the unit will look for an  owned  unit
with  the  'supply' ability. (see info show for information on how to find out
about abilities of units) In this case, the supply unit uses its  mobility  to
use the supplies. After it supplies the unit, the supply unit will then itself
try to re-supply, so that it is possible to  form  a  chain  of  supply  units
reaching back to a headquarters or supply ship.

If after all this the unit can't get enough, it is out of supplies.

Note  that  no  supply  source  will give up enough food to make it starve. In
addition, no supply source will go below 1 of any commodity.

   [##:##] Command: supply *
War band #2 has supplies
   4 units

OTHER USES OF SUPPLY

In general, when any land unit/ship/fort needs shells, it will attempt to draw
them before use, if it does not already have them.

Also,  units/ships/sectors  will  use supply sources to get enough food during
the update so that they do not starve.

NAME
   survey - Show distributions in map form

Level: Expert

SYNTAX
   [##:##]% survey   ?condcond

The  survey  command  shows the distribution of a commodity or resource in map
form.  Sectors which are owned by you, but do not match the  conditional  have
their  current  designation  displayed much as in a map.  Sectors matching the
conditional are shown in one of several ways.

Sectors which have none (or a level of zero) of the item being  surveyed  show
up as a blank.

If    is  a commodity, then sectors having the commodity present will be
shown as a digit from 0 to 9, the digit representing the number of hundreds of
the  commodity  present  in the sector.  Sectors with more than 999 of a given
commodity will be seen as a '$'.

If  is a sector resource, then the 0 to 9 digits will represent the num-
ber  of tens of the resource present in the sector.  Sectors with more than 99
of a given resource will show up as a $.

If your terminal can support standout mode,  then  sectors  selected  will  be
highlighted.

Sectors not owned by you will show up as blanks.

NOTE:  the  syntax  of  this  command  is somewhat bizarre, as the conditional
condcond is for all practical purposes NOT optional if the  survey  is  to
display any values.

This  command  allows  the deity to pick up two sectors and then put them back
down in each-other's location.  It is  particularly  handy  for  changing  the
shape  of  start  islands  when setting up a game.  For example, a piece of an
island may be cut off by a mountain, and so to fix it you could just swap  the
mountain  over  to  some  other part of the island.  All aspects of the sector
(e.g. resources, commodities) get transferred to the new location.   The  only
change that is made is that dist paths are wiped.

SYNTAX
   [##:##]% sweep    route|destination

The  sweep  command  is identical to the recon command, except that if you use
planes capable of minesweeping, they will sweep mines from sectors along their
route.

  represents  a list of planes which are to be performing the intelli-
gence gathering operation.  Only planes which are provided with gas, and  have
sufficient mobility will be successfully selected for the mission.

  represent  a  list of fighter planes which are capable of escorting
the transports all the way to the target.  To be selected, escorts  must  have
fuel and mobility.

  represents  an  assembly point, where all of the planes in the mission
meet before proceeding on to the target sector.  The assembly  point  must  be
owned  by  you,  and  must  not be more than four sectors away from any of the
planes selected for the mission.

Route is a normal empire path specification. You may also give  a  destination
sector  on the command line, or at any time while giving the route, and empire
will use the best path from the current sector to the desired destination sec-
tor.

When  getting  a  path interactively, empire will show you the information you
have (from your bmap) concerning the current area, to help plot your course.

Information given by sweep/recon is not totally accurate.

Sweep/recon missions can be intercepted just like any other mission.   If  the
destination sector is not an airport, then all planes in the mission must have
V/STOL capability.

Planes with the ASW ability will perform a sonar search on each sector as they
fly  through it.  Each sub contact will be reported only once, giving the sec-

they can only sweep 1 mine per overflight of the sector.

Note that a plane must be at least 40%  efficient  before  it  can  leave  the

Level: Basic

SYNTAX
   [##:##]% telegram  [] [[]]

The  telegram  command  allows  non-treaty communication to take place between
representatives.  Currently you are given only 1024 characters per telegram.

The  argument is either  the  number  or  name  of  the  recipient
nation.  You  may  specify as many recipients on the command line as you wish.
Telegrams sent to country #0 appear as prayers, (favors are best  obtained  in
this manner.)

While entering your telegram the system tells you how many characters you have
left.  You end the telegram by typing ^D on a line by itself, or by entering a
line  with  a '.' on a line by itself. A line containing only a '~' will abort
the telegram.

For example:
   [##:##] Command: tel 7 8

   Enter telegram for multiple recipients; end with ^D

NAME
   tend - Transfer commodities between ships

Level: Basic

SYNTAX
   [##:##]% tend    

The  tend  command  allows  transfer of commodities from a particular (supply)
ship to patrol boats, submarines, battleships, etc. while at sea.

If you had cargo ship #16 which had food, and your fleet S  needed  food,  you
could resupply the entire fleet with 20 units of food by typing
   [##:##] Command: tend 16 food 20 S

Requirements  are  that  the  tending  ship  must be in the same sector as the
tended ships, and it must be yours, or belong to a country that considers  you
a  friendly trading partner.  A positive  indicates the amount the tender
will give away, while a negative amount indicates the amount that  the  tender
will  try  to  extract  from each ship. (However, you cannot take goods from a
friendly ship by giving a negative amount)

Only land units with the "assault" capability may be tended between ships.  If
you  wanted  to  tend  land  unit #23 from ship #8 to ship #17, then you would
type:
   [##:##] Command: tend 8 23 land 17
Besides the "assault" capability restriction, tending land units has the  same
effect as though you were simply loading the unit onto a ship.  In particular,
you may tend land units to "friendly" ships in the same sector.

NAME
   territory - Assign various sectors to a specific territory

Level: Expert

SYNTAX
   [##:##]% territory   []

In  Empire,  sectors  may  be given a territory id number.  This number may be
used in conditional statements as in:
   [##:##] Command: census # ?terr=27
The program will then give you a census report for all the sectors  that  have
been assigned the territory number 27.

In  this sense it is essentially an extended realm.  However, you are not lim-
ited to rectangular regions and you have 99 values to choose from.

There are four independent territory fields.  If the optional  field  argument
is empty, field 0 is used.

   [##:##] Command: territory #1 5 1

Would set terr1 field to 5 for all sectors in realm 1.

   [##:##] Command: sect * ?terr1=6&terr2=12

If  terr1 was used to mark different islands and terr2=12 indicated productive
sectors, this would highlight all the productive sectors on island number 6.

Some possible uses include; all sectors distributing to a  particular  sector;
all coastal sectors; all sectors that have armed missiles in them.  And proba-
bly thousands that I haven't thought of. ;-)

To unset a territory, set its value to zero.

Note: terr and terr0 are the same.

Level: Expert

SYNTAX
   [##:##]% test    

The  test  command  lets you check the effect of a proposed move.  This can be
helpful when you're not sure whether you have enough mobility to reach a  cer-
tain location or you wish to compare two possible routes for a move.

The  test  command has exactly the same arguments as the move command and acts
almost the same.  There are two important differences:

   Nothing is actually moved and no mobility is used.

   The move is tested for   irrespective of how much    is
   actually  in the sector.  This is useful for testing a sector which will be
   used as a temporary stopover in a multi-step move to make  sure  the  stuff
   won't get stranded there.

NAME
   threshold - Set commodity distribution thresholds

Level: Basic

SYNTAX
   [##:##]% threshold   

The  threshold command is used to specify the level of a given commodity which
is to be maintained by the sector's distribution  sector.   These  levels  are
maintained by either importing or exporting commodities.  This importation and
exportation is done automatically during an update.  Both imports and  exports
from distribution sectors cost only one-half normal mobility.

In  the syntax,  is the sector or sectors from which the deliveries are
made,  is one of the following:

   c    civilians
   m    military
   u    uncompensated workers
   f       food
   s       shells
   g       guns
   p       planes
   i       iron ore
   d       gold dust
   b       bars of gold
   o       oil
   l       light construction materials
   h       heavy construction materials
   r    radioactive materials

and  is a number specifying the level of commodity which is desired.

The census and commodity reports will indicate distribution thresholds by  the
hundreds  digit  of  the  threshold  level.  In order to have a threshold take
effect, it must be at least one.

Sectors importing or exporting items can be seen by the route command  (marked
with a $) or by the sect command.

Also, note that no distribution center will ship out its last civilian.

NAME
   torpedo - Slip a torpedo to some poor sucker (from a sub or ship)

Level: Basic

SYNTAX
   [##:##]% torpedo  

The torpedo command is used to shoot other naval vessels in a sneaky manner.

The  argument is the victim ship number and the 
argument is the number(s) of your submarine  or  other  ship(s)  with  torpedo
ability.   The program will ask for these if not provided on the command line.
If using the multi-fire option, the program will prompt for targets  for  EACH
firing torpedo ship, if no target was given on the command line.

Your  must meet the following criteria:
   1) It must have torpedo ability. (see info show)
   2) It must have at least 1 gun (torpedo tube)
   3) It must have at least 3 shells (3 shells = 1 torpedo)
   4) It must be at least 60% efficient
   5) It must have some mobility
Meeting  all  these  criteria, your torpedo will be launched toward the victim
ship and a countdown of seconds until the expected detonation will commence.

The range of a torpedo depends on the type of sub, and its  tech  level.  Cur-
rently the range formula looks like this:
     (frng) * (tech+50)/(tech+200)

     [Note: frng comes from show ship capability]

If the target is out of range, you will be told so, (after your torp is in the
water).  See info Hitchance for the chance of a torpedo hitting its target.

If the target ship is not in a direct line of sight but in range, the  torpedo
will  slam into land and you will be notified.  Note that the victim ship will
still see the torpedo being launched and can return a depth charge attack (see
below.)

A  hit will be reported to you as BOOM!, See info Damage for the damage that a
torpedo does.

In order to simulate the real-time situation, your  mobility  will  be  decre-
mented  by mobility equal to 1/2 the cost the torpedo-ship would pay to move a
sector for each torpedo fired; if it goes to zero  (or  beyond)  you  will  be
forced  to  stick  around.   If your torpedo scores a hit, your victim will be
informed of the fact and will be told the number of the torpedo-ship, but  not
the country (so you can deny it).

The victim's only automatic protection against sub attacks is that any ship of
his/hers that is near you and has depth-charge ability  and  has  shells  will
drop  them  on you as depth charges.  Each depth charge does 10% to 40% damage
to your sub, depending on  the  armor  of  the  sub,  and  the  range  of  the
destroyer.

The range a ship can depth charge at is the same as its gun range.

Against  surface  ships launching torpedo attacks, the victim gets to fire all
his ships & sectors within range at the attackers BEFORE the attackers get  to
fire.  Damage done by all defending ships is divided evenly over all attacking
ships.

empire will use the cheapest path (in terms of mobility) from the current sec-

You would move 5 small nukes from 2,0 to 8,0 as follows:
   [##:##] Command: transport nuke 2,0 small 5 8,0

You could move all planes in wing d to -6,0 as follows:
   [##:##] Command: transport plane d -6,0

Note  that  while  transporting,  you may run into any landmines the enemy has
left in your sectors. In that case, the planes  being  transported  will  take
damage. See info lmine for details.

Also,  if  your  enemy  has any units on interdiction mission, then the planes
you're transporting may get hit by them.

Nuclear warheads are transported in heavily armoured vehicles and  are  immune
to land mines and interdiction.

able workforce of at least half the size it would take to build the  ship/land
unit/plane  from  scratch.   To be upgraded, a ship/land unit/plane must be at
least 60% efficient.

Refitting a ship/land unit/plane costs 50% of the initial cost of  a  building
new one, and reduces the efficiency of the ship/land unit/plane by 35%.

NAME
   wait - Wait for a telegram

Level: Expert

SYNTAX
   [##:##]% wait

The  wait command is used to wait until new telegrams are received.  It's most
common use is to wait for an attack, or a reply of some sort.

   [##:##] Command: wait
You have a new telegram waiting ...
   [##:##] Command:

When telegrams arrive you are informed with:

   You have a new telegram waiting ...   if there is just one new one, or
   You have ten new telegrams waiting ...   if there are ten of them, or
   You have several new telegrams waiting ...   if there are very many.

The wait command will eventually time out.

WAIT COMMAND IS DISABLED IN THE NEW SERVER.

NAME
   wall - Send a message directly to all allies terminals

Level: Expert

SYNTAX
   [##:##]% wall []

The  wall command allows instant communication between allied nations.  It may
be called in two different ways.  You can either send your  ally  a  one  line
message as in:
   [##:##] Command: wall Hi there, I'm back from lunch

Or you can send a multi-line message:
   [##:##] Command: wall

   > Everyone ready?
   > OK, let's hit the beaches!
   > .

Note  that  you can end a multi-line wall with either a '.' (period) on a line
all by itself, or by hitting ^D on a line by itself.  Note also that all  mes-
sages are truncated to 60 characters long!

If  you  do  not wish to receive any broadcast messages from your allies, then
you can temporarily turn the feature off by typing "toggle flash".

NAME
   wingadd - Designate members of a wing

Level: Expert

SYNTAX
   [##:##]% wingadd  

The wingadd command is used to specify the wing groupings of your planes.

   [##:##] Command: wingadd  
In the syntax  is the alphabetic character to be used as the wing desig-
nation.  This character can be chosen from the set of upper or lower case  a-z
and  tilde  (~).  The pseudo-wing specification tilde specifies all planes not
currently in any wing.

The specification of planes, , can have one of several syntaxes:

   example     meaning
   -------     -------
   23          plane 23
   2/14/23     planes 2, 14, and 23
   c           all planes currently in wing `c'
   ~           all planes currently in the null wing
   2,3         all planes in sector 2,3
   -1:3,0:2    all planes in the square area bounded by -1,0 & 3,2

All wings, (with the exception of the `~' wing), are limited to  some  maximum
size  and  you will be informed how many planes can be added when this command
is run.

Having planes organized into wings can be very  helpful  in  loading,  moving,
etc.,  in that fewer commands are required to perform these commands on groups
of planes if they can be specified by wing number.

Note that you can remove planes from a wing by adding them to  the  `~'  wing.
e.g.
   [##:##] Command: wingadd ~ A
This command would purge all planes from wing `A'.

NAME
   work - Use engineers to raise sector efficiency

Level: Expert

SYNTAX
   [##:##]% work  

This  command causes a unit with the engineering ability to increase the effi-
ciency of a sector. (see info show for information on finding out unit  abili-
ties)

The increase in efficiency depends on mobility used. It costs a 100% efficient
land unit 6 mobility to raise a sector 1%  efficiency.   Less  efficient  land
units  are  charged proportionally higher amounts of mobility.  For example, a
50% land unit would be charged 12 mobility to raise the efficiency of a sector
by 1%.

If  the  sector  has been re-designated, the working unit will first tear down
the old, then start working on the new effic, in the  same  way  that  sectors
update normally.

NAME
   zdone - Indicate willingness to have an update

Level: Expert

SYNTAX
   [##:##]% zdone [yes|no|check]

The zdone command allows you to say when you are done and ready for an update.

"yes" says that you are ready for an update.

"no" clears any previous "yes" that you did.

"check" checks to see what your zdone state is.

The command will also show you how many countries want an update.  There are 3
possible  update  policies which could be set in this game.  The update policy
is shown in the update command.

Your zdone state is cleared when an update occurs.

1. No demand updates.  If so, then this command is useless.

2. Updates occur upon demand, right after the last  person  sets  zdone.   The
threshold  at which a demand update occurs is configurable, and may be seen in
the update command.

3. Demand updates occur at specific times.  If enough countries have set zdone
at  one  of  those times, then an update will occur.  The times may be seen in
the update command.

NAME
   Attack - Details for attack, assault, paradrop, board and lboard

Level: Expert

This   info   page   describes  5  different  commands:  "attack",  "assault",
"paradrop", "board" and "lboard".  These are the four commands that you use to
take something (either a ship, land unit or a sector) from the enemy by force.

Note that much of the board information relates  to  the  lboard  information,
just apply it to a land unit instead of a ship.

   A combat has 15 steps:
   (1)  Ask the aggressor for the target sector/ship.
   (2)  Ask the aggressor further details about the offensive force.
   (3)  Estimate the odds and possibly ask the aggressor for confirmation.
   (4)  Move reacting defensive units to the target sector.
   (5)  Calculate defensive support.
   (6)  Fight.
   (7)  Spread the plague.
   (8)  Take mobility and supply from land units.
   (9)  Send reacting units home.
   (10) If successful, the aggressor takes the target sector/ship.
   (11) Remove mobility and efficiency from the target sector/ship.
   (12) Remove mobility from the aggressor's sectors/ship.
   (13) Possibly ask the aggressor for mil and units to move into the target.
   (14) Possibly interdict the aggressor's mil and units as they move.
   (15) Charge the aggressor BTU's.

(1)  Ask the aggressor for the target sector/ship.

   Sea, sanctuary, and wasteland are illegal targets.
   You may not assault a mountain.
   You may not paradrop into a mountain, capital, city, or fortress.
   You may only board a ship from the sector the ship is in, you may
   not board a ship which is faster than your ship, and you may not board
   a submarine at sea.
   You may only board a land unit from the sector the land unit is in.

The  "assault"  command is the only command which will let you attack your own
sector (you can use this to get mil & assault units on shore).  You should not
"attack" unowned land (see info explore).

If  the  SLOW_WAR  option  is enabled, you will not be able to attack a sector
owned by a country you are not AT_WAR with, unless you are the  old  owner  of
the sector.

If the SNEAK_ATTACK option is also enabled, you can attack ONE sector owned by
a country you are not AT_WAR with, paying $5K  for  the  privilege.  Once  the
sneak  attack  is  done, you will automatically declare war against the enemy,
and go through the normal SLOW_WAR sequence before you can attack  again  (see
info relations).

(2)  Ask the aggressor further details about the offensive force.

When  you board, you are asked for a ship or sector to board from.  If you are
attacking or assaulting, then you have the option to specify whether you  want
your  forts/ships/plane/units to support your attack.  If no support is speci-
fied, then it is assumed that you want support from all sources.

If you are not paradropping, then you will be asked  for  mil  and  units  you
would like to attack with.  You must always leave at least 1 mil in the sector
or ship you are attacking from, so you may never attack with all of  your  mil
out  of  a sector or ship.  The following limitations apply to the aggressor's
mil:

   Attack:  You are limited by the mobility of the attacking sector
            according to the mob-cost to move the mil into the target sector.
   Assault: If the target sector contains mil, then you may only attack with
            1/10th of your mil on board, unless your ship has "semi-land"
            capability in which case it is 1/4th, -or- if your ship has
            "land" capability in which case there is no limitation.
   Board:   When boarding from a sector, the sector must have mob.  When
            boarding from either a ship or a sector, the number of mil
            you may board with is limited to the maximum number of mil that the
            target ship can hold.  Note that you can board land units
            from a sector only.

   The following restrictions apply to the aggressor's land units:
   A land unit must have mobility and be in supply (see info supply) in
   order to be able to enter the combat.  Land units with "security",
   "supply" or "flak" capability may not attack.  Also, you may not
   attack with artillery units (i.e. if frg > 0).  Only land units with "assault"
   capability may assault or board.
   Attack:  The land unit must have at least as much mobility that it
            would cost for it to march into the sector.
   Board:   You may only board with as many land units as the target ship
            can hold.  You cannot board a land unit with other land units.

When asked whether you'd like to include a certain land unit  in  the  combat,
you will be given a prompt ending in [ynYNq?].  At this prompt, you can type:

   y - yes this unit
   n - no this unit
   Y - yes all units in this army
   N - no all units in this army
   q - quit attack
   ? - print this help message

(3)  Estimate the odds and possibly ask the aggressor for confirmation.

   The offense strength of your land units is mil * off where "mil" is the
   number of mil in the unit, and "off" is the offense multiplier of the
   unit (see show land stats), with the following exceptions:
   Assault: If the unit doesn't have "marine" capability, then its
            offense strength is cut in half.
   Board:   If the unit doesn't have "marine" capability, then its
            offense strength is equal to half of the number of mil in the unit.

The  total  offense strength is the number of mil plus the offense strength of
all offensive units.  This number is then multiplied by the offense  value  of
the  sector  the  mil  and  units  are attacking from (see show sector stats).
Ships have an offense value of 1.

The defense strength of a land unit is the total number of  mil  in  the  unit
times  its  defense  multiplier  (see show land stats).  The only exception to
this is non-marine land units on ships which have  a  strength  equal  to  the
total  number  of mil in them.  The defense strength of units out of supply is
cut in half.  The defense strength of fortified units is multiplied by (127  +
fortification) / 127.

The  total  defense strength is the number of mil plus the defense strength of
all defensive units.  This number is then multiplied by the defense  value  of
the  sector  the  mil  and units are in (see show sector stats).  Ships have a
defense value of 1  +  def/100  (see  show  ship  stats).   You  can  use  the
"strength" command to see the defense strength of your sectors.

Now,  When  your  scouts  estimate  the defense strength, they only count land
units and mil that they see.  If your scouts didn't notice the  efficiency  of
the  defending units, then they assume that they are at 100% efficiency.  Your
scouts also assume that none of the enemy  units  are  fortified.   Once  your
scouts  have come up with an "estimated defense strength", then that number is
compared with your offense strength.  The output so far might look like this:
   [##:##] Command: attack -14,2

   -14,2 is a 100% 5 harbor with approximately 0 military.
   Number of mil from headquarters at -15,3 (max 108) : 10
   cavalry #7 has a base attack value of 44
   attack with cavalry #7 in -15,3 (~ 100%) [ynYNq?] y
   cavalry #24 has a base attack value of 44

                Initial attack strength:      108
   Scouts report defending unit: inf1  infantry 1 #22 (efficiency 71, tech 169)
   Scouts report defending unit: inf2  infantry 2 #41 (efficiency 94, tech 169)
   Scouts report defending unit: inf2  infantry 2 #42 (efficiency 94, tech 173)
   Scouts report defending unit: inf2  infantry 2 #43 (efficiency 65, tech 139)
             Estimated defense strength:     1118
                         Estimated odds:        8%

Note that your estimated odds are  calculated  before  any  enemy  units  have
reacted,  and  before  support multipliers are calculated, so they will not be
particularly accurate.

(4)  Move reacting defensive units to the target sector.

If the target is not a mountain, then defensive units in  nearby  sectors  may
react.   Defensive  units will keep reacting until the defense strength is 1.2
times the offense strength.  The following restrictions apply to reacting land
units:

   - The efficiency of the unit must be higher than it's retreat percentage.
   - The unit must be in supply.
   - The unit must have enough mobility to get to the target.
   - The unit must be in range.

If  the  unit is in a 60% efficient headquarters, then 1 is added to its reac-
tion radius.  If it is on "reserve" mission, then 2 is added  to  the  radius.
Note  that  you  can  limit  the  reaction radius of your land units using the
"lrange" command.

(5)  Calculate support.

For attack and assault, both offensive and defensive  support  is  calculated.
For  paradrop,  only defensive support is calculated, and for board and lboard
there is no support (however, defending ships within range will  fire  on  the
boarding ship or sector before the fight if boarding a ship).

The  aggressor's  support is calculated based on what the aggressor asked for.
Defensive support is only called in to the extent that it would be useful.  If
the aggressor outnumbers the defender 10-to-1, then the defender will not have
any support.  Otherwise, the defender will keep calling in support  until  its
strength is at least 1.2 times the offense strength.

Fort,  ship, and unit support is simply those forts, ships, and units in range
that can fire (see info fire).  Note that ships and units on missions will not
fire  support.   Plane  support  comes from those planes on "support" mission.
The support multiplier is

   1.0 + fortdamage/100 + shipdamage/100 + planedamage/100 + unitdamage/100.

Ships/forts/units belonging to allies of the combatants will support, if  they
are  at war with the other combatant. (For example, if A is allied with B, and
at war with C, and A attacks C, things belonging to B will support the  attack
if  able.  The same is true for defense. If C attacks A, the B stuff will help
defend A)

After these four supports are calculated, then land mine support is  added  to
the  defense  support.  Defending land mines add (number of mines) * 0.02 to a
maximum of 0.40.  If there are attacking engineers present, this number is cut
in half.

(6)  Fight.

Total offense and defense strength are multiplied by their support multipliers
to obtain the final combat strengths.  From this, odds are  calculated.   Then
in  each  "round", a chance according to the combat odds determines whether an
aggressor or defender troop is lost.  Troops killed in combat are first  taken
from  the  mil  (from  the  sector containing the most mil), and then from the
units (from the unit containing the most mil).  Combat odds  are  recalculated
and the process continues until there is a victor.  Each time there is a casu-
alty, a character is printed:

   ! means a defending soldier bit it
   @ means one of your soldiers went doan

If the effiency of a land unit is less than its  retreat  percentage  when  it
gets  hit,  then it will need to make a morale check.  The chance of failing a
morale check is (retreat percentage - efficiency).  If the unit has nowhere to
retreat  to, then it takes "extra losses" which amounts to an extra 10% docked
from its efficiency.  Otherwise, the land unit retreats to the adjacent sector
containing  the  maximum  number of civs.  Units will never retreat into moun-
tains.

Also note that once all of the military on a land unit are  killed,  the  land
unit  stops  defending.   What  this  means  is  that  a  land unit can become
"trapped" in an sector if an enemy takes it over after killing all  the  mili-
tary on a land unit while the land unit may not be destroyed.

When  planning  an  attack remember that overwhelming forces greatly increases
your odds; i.e., attacking 10 men with 40 will result  in  your  losing  fewer
troops than if you had attacked with 20.

(7)  Spread the plague.

If  any combatant in a battle is infected with the plague, all potential comn-
batants in the battle are infected as well (if they do not already  have  some
level of plague already.)

(8)  Take mobility and supply from land units.

The  "aggresor  loss  factor"  is  equal to the number of aggressor casualties
divided by the total number of aggressor troops that went into  the  conflict.
Similarly,  the  "defender  loss  factor"  is calculated.  Then each land unit
loses mobility equal to 10 * (loss factor).  Defensive land units  on  reserve
mission only lose half of that.  Also there is a chance equal to the loss fac-
tor that the land unit will use up some of its supply (see info supply).

(9)  Send reacting units home.

If the defending land unit did not retreat, then send it back to where it came
from at no mobility charge.

(10) If successful, the aggressor takes the target sector/ship.

Either  1  aggressor  mil  (first  choice) or one land unit (second choice) is
automatically moved into the conquered ship or sector  to  occupy  it.   Since
this  mil  or  unit is effectively "chasing out" the remnants of the defending
forces, the defender will not interdict it (because he won't  want  to  damage
his forces with "friendly fire").

   This is what happens to the sector when you take it:
   - All delivery and distribution information is wiped.
   - The production in the sector is stopped (see info stop).
   - Planes in the sector owned by the player you just took the sector from
     lose 30 plus random(100) efficiency and go to 0 mob. If the new efficiency
     is less than 10%, the plane is blown up.
   - Units in the sector owned by the player you just took the sector from
     lose 30 plus random(100) efficiency and go to 0 mob. If the new efficiency
     is less than 10%, the unit is blown up.
   - The avail is set to 0.
   - New che are created (see info Guerrilla).
   - Set the loyalty of the sector to 50 (see info Loyalty).
   - Reduce the mobility to 0.
   - The civs in the sector become "conquered populace" (see info Occupation).

   When you take a ship:
   - Mission, retreat info and fleet info is wiped.
   - Planes and land units on the ship are reduced to 10%.

   When you take a land unit:
   - Mission, retreat info and army info is wiped.
   - Planes and land units on the unit are reduced to 10%.

   When you take someone's capital, the defender loses half of their
   money or $3000 whichever is greater.  If the defender wasn't broke to
   begin with, then the aggressor gets half of their money times (1/5 +
   4/5 * efficiency of the sector).

(11) Remove mobility and efficiency from the target sector/ship.

The  efficiency  of the target sector or ship is damaged by a percentage equal
to the total number of casualties divided by ten.

If the target is a sector, then it will lose an amount of  mobility  equal  to
the  maximum  of  20  and  a percentage of the mobility equal to the number of
defender mil casualties divided by the total number of mil  that  were  origi-
nally  in  that sector.  So if for example, your casualty fraction was 70/100,
and your sector  started  with  50  mobility,  then  you  would  lose  max(20,
50*70/100) = max(20, 35) = 20 mobility.

(12) Remove mobility from the aggressor's sectors and ships.

The pre-combat mobility costs are:

   Attack:  Remove mobility equal to the mob cost to move the mil into the
            target sector.
   Board:   If boarding from a ship, the cost is the half of the speed of the
            defending ship times the efficiency of the defending ship.
            If boarding from a sector, the cost is the number of boarding
            mil divided by 5. This applies for boarding of ships and land units.

Only  sectors  are  charged  an additional post-combat mobility cost.  In this
case, the amount of mobility the sector loses is  calculated  using  the  same
formula as is used for the defending sector's mobility cost.

(13) Possibly ask the aggressor for mil and units to move into the target.

If  the  combat was an assault, paradrop, board or lboard, then all victorious
mil and units are automatically moved into the target.  The mil are  moved  in
with  no mobility charge.  If the combat is assault, then the mil will take an
amount of food with them proportional to the  number  of  people  leaving  the
ship.  The mobility cost to land units is as follows:

   Assault: If the land units are attacking from a ship with "land" capability,
            then land units are charged (update mob) mobility, except for
            "marine" units which are only charged half of that.  For all
            other kinds of ships, land units go to -(update mob), except for
            "marine" units which go to zero.  Here, (update mob) refers to
            the amount of mobility that units gain at the update.
   Board:   Marine units are charged 10 mobility and other land units are
            charged 40.

In  the  case of attack, the aggressor is asked what they'd like to move in as
follows:  First, the aggressor is asked how many mil they would like  to  move
in from each attacking sector.  This number is limited by the amount of mobil-
ity left in the attacking sector.  Then the  aggressor  is  asked  which  land
units  they'd  like  to  move into the sector with the same [ynYNq?] prompt as
above, the only difference being that 'q' now means "don't move anything  in".
The mobility costs here are the same as for "move" and "march".

(14) Possibly interdict the aggressor's mil and units as they move.

Post-attack  interdiction  only  occurrs  in  the "attack" command (and not in
"assault", "paradrop", "board" or "lboard").  When you move your mil into  the
target  sector after an attack, you will risk the same chances of interdiction
(number of mil / 200) and stepping on land mines (see "info lmine") as if  you
were moving them using the "move" command.

Similarly,  once  you  have specified which land units you'd like to move into
the conquered sector, then all of your units will move in at  once,  and  they
will  be interdicted in the same way as though they were being moved using the
"march" command, including the danger of stepping on land  mines.   Note  that
there  is  no post-attack interdiction and no danger of stepping on land mines
if the INTERDICT_ATT option is disabled (see version).

(15) Charge the aggressor BTU's.

The BTU cost is equal to 0.5 + (the total number of casualties) * 0.015.

   Autofeed - How to use fishing boats to automatically feed your civs

Level: Expert

     For years now people have been setting up large groups of fishing
   boats to feed their island.  These groups get very large and are
   difficult to keep track of.

     This is an example of how to set up a fleet of fishing boats
   so they will take their food produced each update and drop it off
   at the harbor of your choice.

     See 'info order' for a complete description and example of
   syntax for the 'order' command.

   map #1
      00000000001111111
      01234567890123456
    -4. . . . . . . . .

     0. . . . . g m . .
     1 . . . . f * w h .
     2. . . . . c + + .

   You have ships  0,12,88 in the harbor 15,1
   Sector 16,0 has a very good fert of 93 so you want to use that
   as your fishing grounds.

   1) move your ships to sector 16,0
   "nav 0/12/88 16,0"

   2a) set up autonav using the 'order' command.
       "order 0 des 15,1 16,0"
       This will establish a circular trade route.

   2b) set up food levels for the ship
       "order 0 level 1 start food 30"
       "order 0 level 1 end   food 30"

       You can also use a global '*' or a fleet letter here.
       "order * level 1 start food 30"
       "order * level 1 end   food 30"

       "order F level 1 start food 30"
       "order F level 1 end   food 30"

       NOTE: You should set BOTH start and end fields to insure
             autofeed will work correctly and set them at the
             same levels!

       NOTE: if you are using autonav with normal cargo ships.
       Fishing boats are a special case to the autonav code.
       This setup will only work correctly with fishing boats.
       If you want to use autonav with cargo ships please use
       the examples found in the 'order' command.

   repeat 2a,2b for other ships in the area.

   During the update your fishing boats will now move to the harbor at
   15,1 unload food until it reaches 30, then move back to 15,1 and STOP.
   If you're using fishing boats that require fuel, i.e. fb2
   when the ship enters the harbor, and the fuel level is at 0, the
   autonav code will automaticly refuel the ship for you.
   So unless the ship gets sunk, or something happens to it, like the
   civs starve on board if you don't leave enough food on it,
   the ships will continue to feed your country and you won't even need
   to think about them.

   The Max limit that autonav will stockpile is 99999 units.
   So if your sector get overcrowded the ship will sit in the harbor
   until it can unload all of its food.

NAME
   Autonav - Giving ships automatic sailing orders

Level: Expert

In  a  very short while after acquiring ships the effort of moving ships after
every update gets very boring.  And the more ships you have, the more work  it
is.   Hence the concept of autonavigation.  Like any self-respecting dictator,
you don't personally drive your  ships  around  (except  when  you  want  to),
instead  you  command  you  ship captains to take their vessels to a specified
destination.  This is done via the order command.

Each ship can be ordered to proceed to a destination.  During each update, the
ship  will  try  and use ALL the mobility it has and use the shortest possible
path.  It will also avoid any known mines (sectors marked with an 'X'  or  'x'
on your bmap).  Note that this movement is all done before mobility is accumu-
lated, so that after the update is complete the ship will have a full  updates
worth of mobility in case you need to move it by hand.  Should a ship be fired
upon by forts or strike a mine they will stop moving!  This will prevent  your
ship  from  foolishly  getting sunk in enemy waters.  The order command covers
many special cases.

The autonavigation capability is dependent upon the per country  map  database
accessed  via  the  bmap command.  If you order a vessel to a destination that
causes it to cross a previously unexplored area,  the  ship  will  attempt  to
cross  that  area  as if it were water.  One of the features of the bmap func-
tionality is that when a ship is navigated, it automatically uses its radar to
see the local sectors (much like real life).  This sector information is added
to the per country map database.  Thus upon running into a previously  unknown
obstruction,  that  information  is  added to the map database and on the next
update, a new path to the destination will  be  calculated  which  avoids  the
obstruction.  This process applied iteratively means that a ships will eventu-
ally find its way around any obstruction, provided that  a  path  exists.   In
reality,  this  is  a limit to this process.  In order to limit the processing
that is done to find a path to the destination, the internal  path  string  is
limited to 28 characters.

The  other  capability  of the autonav function is autotrading.  By specifying
two destinations and two commodities,  the  ship  will  move  back  and  forth
between the two destination loading and unloading the appropriate commodities.
Specific examples can be found in the order info file.

The same rules for navigating, loading, and unloading apply for Autonavigation
as they do when you do these things by hand, namely that you may only use har-
bours owned by nations which consider you to be  a  friendly  trading  partner
(see info relations).

NAME
   BTU - How BTUs are generated

Level: Expert

It  takes  time  for decisions to be made by top level officials, and it takes
time for their orders to reach those who execute them.  The potential of  your
government  to  process new information is measured in Bureaucratic Time Units
(BTU).

BTUs are generated in real-time based on the number of civilians that  are  in
your  capital.  Every time you log out and in again, the server calculates how
long you've been away, and based on that time awards you a certain  number  of
BTUs.

Here is the procedure for determining how many BTUs you get:
If the game is a blitz, then as soon as your BTUs go below zero, then
they are automatically set back to 512.

(1) Count the number of civs generating BTUs.
  civs = maximum(999, number of civs in your capital sector)
  Note that if you don't have a capital, then you will get _no_ BTUs.

(2) Find out how many civs are required to make one BTU in one time unit.
The "version" command will tell you how many civilians are required to
produce one BTU in one time unit.

(3) Calculate how many BTUs your cap produces in one time unit.
Divide the number of civs generating BTUs (step 1) by the number of
civs required to produce one BTU in one time unit (step 2).  If your
capital is in a mountain or has zero efficiency, then multiply by
1/200.  Otherwise, multiply by (sector efficiency) / 100.  Note that
0% capitals and mountains generate BTUs as if they were 0.5% capitals.

(4) Calculate how many time units have passed.
The number of "Time units" (TU) since your last login is:
  TU = (number of seconds since last login) / (number of seconds per ETU).
The "version" command will tell you how many seconds are in an
"Empire time unit" (ETU).  If more than 336 time units have passed
since your last login, then set TU = 336.

(5) Calculate how many BTUs you get.
Multiply the number of BTUs your cap produces in one TU (step 3) by
the number of TUs which have passed (step 4).  This is how many BTUs
you get.  Note that there is a limit to how many BTUs you can have at
any given time.  This number is usually 512 but can be changed by the deity.

EXAMPLE: say you had a 100% capital containing 500 civs.
Suppose that version said:

It takes 25.00 civilians to produce a BTU in one time unit

Then first you would divide 500 by 25 to get 20.  Now since your cap
is 100% efficient, you would multiply 20 by (100/100) and so the civs
in your cap would produce 20 BTUs per time unit.  Now suppose that
version said:

An Empire time unit is 1440 seconds long.

and suppose that 1 day had passed since the last time you logged on.
Then that means that the number of time units which have passed is:
  TU = (number of second in a day) / (number of seconds per etu)
     = (24 * 60 * 60) / (1440)
     = (1440 * 60) / (1440)
     = 60
(Note that another way to find out how many time units there are between
updates is to find out how many ETU's there are per update.)
  Lastly, we multiply 20 by 60 to get 1200 BTUs.  But since the
maximum is 512, we would have 512 BTUs.  Note that if your capital had
been in a mountain sector, then you would have only gotten 6 BTUs in
24 hours.

NAME
   Bridges - Building and destroying bridges

Level: Expert

BRIDGES

Normally bridges can only be built from bridge-heads. (See info Sector-types).
If the EASY_BRIDGES option is in use, bridges can be  built  from  any  sector
that  has  enough  hcm  (heavy construction materials) and workforce (see info
show and the show command), providing you have enough money, and your technol-
ogy level is high enough.

Bridges can only be built over water sectors.

If  the  EASY_BRIDGES option is in use, you do not need to use bridgehead sec-
tors (although the sector you build from must still  be  at  least  60%  effi-
cient),  and  the sector the bridge span is to be built in must be adjacent to
at least 1 non-sea, non-bridge span sector. Note that you do not have  to  OWN
the  sector  is will be adjacent to, it just has to exist. This means that you
can build, for example, a 2 sector bridge out to an unowned island.

To find out the required amounts of materials, workforce, and  money  use  the
show command.

Bridge  spans cannot be re-designated.  A bridge span will collapse when it is
below 20% in efficiency, so shelling will destroy one, as will nuclear weapons
and bombing.

If  the  EASY_BRIDGES option is NOT in use, a bridge will also collapse if its
bridge-head sector goes below 20% or is re-designated.

NAME
   Citizens - Work, starvation, and general management of your citizens

Level: Basic

Taxation of the civilian populace is one of the main providers of income to an
Empire nation (gold bars in banks, trade ships, and taxes from uws  being  the
only  other sources of income in the game).  Also, only friendly civilians can
be enlisted into the army, navy and air force.

The loyalty of a given sector, also known as the willingness of  the  civilian
population  to work, is initially 100% -- that is, all of the people are work-
ing.  In the event that the sector is captured, starves, or  falls  victim  to
revolutionary  subversion, the work of the sector will decrease.  This will be
shown by the work % decreasing.

If people starve in a sector, the amount of work they do drops to  0  (because
they are too weak to work).

If  a  sector is a conquered sector, a star * will be shown in the appropriate
column on the census report.  Friendly sectors allow enlistment  of  military,
as well as the ability to move the civilians freely about.  Occupied civilians
will not move, and friendly civilians cannot enter these  sectors.   In  addi-
tion, occupied civilians will not serve in the armed forces.

If  the thought of not being able to move conquered populace bothers you, then
you have the option of converting these conquered  people  into  uncompensated
workers, involving the expenditure of BTU's and money (for the paperwork).  If
all the conquered people in one sector are converted to uw's, then the  sector
is then marked as yours.

If  the people in a sector are unhappy (due to starvation, subversion, or lack
of happiness) they can go on strike and cease working.  You can get them  back
to  work  by  heavy-handed  military control (placing one military for each 20
striking civilians).

Finally, your populace requires happiness to keep their  enthusiasm  for  work
going.  As technology and education increase, your work force expects to share
in the increased levels by getting more consumer  items  (VCR's,  BMW's,  etc)
represented  by  happy  strollers.   If  you don't have at least one happiness
point per two units of education, and a point for each forty  units  of  tech,
your people will not be happy.

NAME
   Damage - How much damage stuff does

Level: Expert

It is possible to be damaged by shells, bombs, land mines, sea mines,
and nuclear blasts.  This info page shows you how much damage each of
these things does.  In the following formulas, random(x) means a
random number from 1 to x.  Once the damage has been calculated, then
it is applied.  Damage applies to different kinds of things in
different ways (see below).

1. Calculating the damage

Shelling
You can be shelled by a fort, artillery unit, ship, depth-charge, or torpedo:
       fort damage = guns * eff * (random(30) + 20) / 7
       unit damage = guns * eff * (5 + random(6))
       ship damage = guns * eff * (10 + random(6))
      depth damage =    2 * eff * (10 + random(6))
       torp damage = 40 + random(40) + random(40)
Note that for forts, a maximum of 7 guns may be fired.

Bombs
A plane drops a number of bombs equal to the "load" the plane can carry.
Each bomb does the following damage:
     blam: 1 + random(6)
     Blam: 5 + random(6)
     BLAM: 8 + random(6)
When pinbombing a ship, plane, or land unit, damage is doubled.
Whether you get a blam, Blam, or a BLAM depends on the accuracy of the
plane and the difficulty of the target (see info bomb).

Land mines
Land mines damage commodities by random(20) and land units by 10 + random(10).
If the land unit is an engineer, then the damags is cut in half.

Sea mines
Sea mines damage ships 22 + random(20).  If the ship can sweep, then
the damage is cut in half.

Nuclear Detonation
Damage from nuclear detonation uses the following formula.  From
"show nuke stats", you see that each nuke has a certain blast radius
and %damage.  If you are groundbursting, then multiply the radius by
2/3.  If you are airbursting, then multiply the radius by 3/2.  Now
based on the distance from gound zero, the nuke does the following
amount of damage:

Groundburst: dam / (dist + 1)
   Airburst: 0.75 * dam - 20 * dist

For the small, medium, and large nukes currently in the game
(damage 80, 90, 101 and radius 1, 2, 3) the following damage is obtained:

         Groundburst          Airburst
         0       1            0       1       2       3
small   80                   60      40
med     90      45           68      48      28
large    /      50           76      56      36      16

2. Applying the damage

Once you know how much damage the bombs or whatever have done, then
you apply the damage to what was hit.  In the calculations below,
%damage will never be larger than 100%.  If it is, then we just say
that the %damage was 100%.  Once we have the %damage, then we apply it
as follows:

new efficiency = (old efficiency) * (1 - %damage / 100)

For example a 50% ship hit for 10% damage would go down to 45%.

The following formulas show you how to get %damage from damage.  Note
that these formulas are used in all cases _except_ nuclear damage.  In
the case of nuclear damage, %damage is always equal to damage (except
for planes hardened in silos which subtract their "hardened" value
directly from the damage).

Ship
%damage = damage / (1 + def / 100)

Land unit
%damage = damage * (vul / 100) * (127 / fortification + 127)

Plane
%damage = damage

Sector
sectdamage = damage / ((sectdef - 2) * eff + 2)
%damage = (100 * sectdamage / (sectdamage + 100))
commodities take %damage (bars take no damage and people take 0.4 * %damage)
land units take 0.3 * %damage
planes take no damage

Commodity
%damage = (100 * damage / (damage + 50))
bars take no damage
civs, mil, and uws take 0.4 * %damage

NAME
   Education - How Education is calculated at the update

Level: Expert

Education  is  important  for  both  technology and research production.  Your
country will not be able to produce technology or research unless your  civil-
ians have an education of at least 5.  (See "info Products" for more details).

The nation command will display, among other things,  your  current  education
level.

This is how your new education level is determined every update:

(1) Graduates are produced in schools
See "info " or the "production" command to find out how many
Graduates you are going to produce.  Your update telegram will tell
you the class of graduates produced in your various schools in a line
like this:
  a class of graduates (135.00) produced in 3,1

(2) Calculate your education production efficiency
The higher your population, the lower your education p.e., as it takes
more graduates to maintain the same overall level of education.  Note that
with low population you education p.e. can be greater than 1.
The version output will contain a line like this:
  Education p.e. requires 1 class of graduates per 10000 civ.

Your education p.e. is now calculated as follows:
education p.e. = "civ. per graduate" /
           "total pre-update civilian population"

number of graduates produced = class of graduates * education p.e

For example, lets say you have a pre-update civilian population of
40,000 and have produced a class of 260 graduates.  Your education p.e.
would be 10000 / 40000 = .25 and your number of graduates would be
260 * .25 = 65

 (3) Calculate edu delta from the number of graduates
"edu log base" is always 4.0 and "easy edu" is always 5.0.
To find out what your edu delta for the update will be, subtract "easy
edu" from the number of graduates you are producing and call
this number "over easy".  Now divide "over easy" by the log of ("over
easy" + "edu log base") base "edu log base", and then add "easy edu" back.
Simple eh?  ;-)

OK, here's an example:
Say you are producing 65 graduates.  Then your "over easy" would be 65
- 5.0 = 60.  Now the log of (60 + 4.0) base 4.0 is 3 (since 4 to the
power 3 is 64), so our edu delta will be 60/3 + 5 = 25.

(4) Calculate your new education as a weighted average
The version output will contain a line like this:
  Education is averaged over 192 time units
And the number of etus per update is printed in the version output as:
  An update consists of 60 empire time units.

Your new education is now calculated as follows:
"new edu" = ("old edu" * "average etus" + "edu delta" * "etus per update") /
            ("average etus" + "etus per update")

So if, for example, your old education level was 40 and your "edu

NAME
   Fallout - The long lasting effects of nuclear war

Level: Expert

This page describes fallout, and some of its effects.

Fallout is the result of nuclear bombs going off.  It is basically
just radioactive particles that float around in the air.

After nuclear blasts, these particles are thrust into the atmosphere,
and take a long time to dissipate.  In addition, these particles
may spread from sector to sector.

When a sector has fallout, during the update, things in that sector
may die, melt, whatever from the radiation.  The way it works is this:

1) All sectors that have fallout are checked, and things there are
   affected by the fallout.  People die, commodities melt, etc.  This
   includes anything on land units and on ships within that sector.

2) Next, fallout may spread from sector to sector, depending on the
   amount of fallout in the sector.  Note that fallout will spread
   outward from ground zero, in all directions, at a maximum rate of
   1 sector per update.

3) Lastly, fallout decays.  Any fallout that is left decays.  Decay
   usually happens in 1/2 life mode, which means 1/2 the given fallout
   in a sector (after spreading around) dies...

Finally, if you are reading this info page, it probably means that
you are trying to figure out what fallout is going to do to your
country.  Well, good luck, so are we. :)

NAME
   Flak - How flak works

Level: Basic

This page describes flak, and how it works.

Flak is created from gunfire when enemy planes fly overhead.

The way that flak works when planes fly over a sector is:
 * Sector flak is fired.  Up to a maximum of 14 guns can fire
   before being scaled.
 * Land unit flak is then fired.  Up to a maximum of 14 guns can
   fire before being scaled.  Only 'flak' capable units will fire
   in this volley (see "info show"), and only the guns loaded onto
   a land unit are counted in the # of guns firing.
 * Ship flak is then fired.  Up to a maximum of 14 guns can fire
   before being scaled.
 * Defensive planes then intercept.

In  all  of  the above flak rounds, once the maximum # of guns firing has been
determined, the # of guns is then scaled by your country's  tech  factor,  and
then  doubled.   So,  for  example, if you had 14 guns firing, and have a tech
factor of 35%, you would have a total of (14 * .35) * 2 = 10 (after  rounding)
guns firing.

In  addition,  if you are pinbombing a land unit or a ship, when you make your
bombing run, the specific unit/ship you are bombing gets to fire flak  at  you
again.  This number of guns firing flak in these cases is NOT scaled after the
number of guns is determined.

When a sector fires flak, the amount of shells required is the # of guns fired
divided by 2.  If not enough shells are available, either no flak is fired, or
the flak is reduced to the number of shells available.  Note that  the  shells
are not consumed during flak fire, they just need to be available.

When  a ship fires flak, at least 1 shell must be available.  If no shells are
available, no flak is fired.  Note that the shell is not consumed during  flak
fire, it just needs to be available.

Land  units  use no shells when firing flak.  Any land unit with an aaf rating
of > 0 will fire flak when pin-bombed.

The formulas for determining the # of guns fired in a general volley is:
Sector:
    guns = (guns in sector);
    if (guns > 14)
        guns = 14;

Ship:
    guns = 0;
    for (each ship in the sector)
        guns += min(guns, guns able to fire) * (techfact of ship) * 2;
    if (guns > 14)
        guns = 14;

Land unit:
    guns = 0;
    for (each land unit in the sector)
        guns += (aaf rating) * (techfact of unit) * 3;
    if (guns > 14)
     guns = 14;

Then, for each of the above general flak volleys, the # of guns is scaled like
so:
    firing = guns * (techfact of nation) * 2;

On specific bombing runs, the # of guns firing is determined by:

Ship:
    guns = min(guns, guns able to fire) * (techfact of ship) * 2;

Land unit:
    guns = (aaf rating) * (techfact of unit) * 3;

The # of guns in these cases are NOT scaled.

techfact is determined by:
    techfact = (50.0 + tech) / (200.0 + tech);

Once  the  number  of flak guns firing has been determined, the planes have to
fly through it.  The plane may have to fly through flak up to 4 times in  each
sector, depending on circumstances.  They are:

    1) Fly through general sector flak (if any)
    1a) fight in a possible dog-fight
    2) Fly through general ship flak (if any)
    3) Fly through general unit flak (if any)
    4) If pinbombing, fly through specific unit or ship flak (if any)

To  figure  out the damages that a plane takes each time it flys through flak,
the following formula's are used:

    flak = # of guns firing.
    flak = flak - (planes defense + 1);
    if (plane is stealthy)
        flak = flak - 2;
    if (plane is half stealthy)
        flak = flak - 1;
    if (flak > 8)
        mult = flaktable[15] * 1.33;
    else if (flak < -7)
        mult = flaktable[0] * 0.66;
    else {
        flak += 7;
        mult = flaktable[flak];
    }
    mult *= flakscale;
    damage = ((random number from 1 to 8) + 2) * mult;
    if (damage > 100)
        damage = 100;

    plane's eff = (plane's eff) - dam;
    if (plane's eff < 10%)
        plane is shot down
    else if (chance((100 - (plane's eff)) / 100))
        plane aborts mission
    otherwise the plane continues on it's mission

For the above, use this table:

    flaktable[0] = 0.20
    flaktable[1] = 0.20
    flaktable[2] = 0.25
    flaktable[3] = 0.30
    flaktable[4] = 0.35
    flaktable[5] = 0.40
    flaktable[6] = 0.45
    flaktable[7] = 0.50
    flaktable[8] = 0.50
    flaktable[9] = 0.55
    flaktable[10] = 0.60
    flaktable[11] = 0.65
    flaktable[12] = 0.70
    flaktable[13] = 0.75
    flaktable[14] = 0.80
    flaktable[15] = 0.85

and a flakscale of 1.75

NAME
   Food - How much people eat at the update

Level: Expert

In  Empire,  as  in the real world, everyone must eat to survive, (see SPECIAL
NOTE below for the exception).  All of these  numbers  below  are  subject  to
change.  Execute the version command to get some of this information.  Ask the
deity for the rest.

Each civilian or military eats 0.0005 units of food per time unit, (i.e. 0.024
units of food a day in non-Blitz Empire).

The ability of a sector to grow food is indicated by its fertility.  Fertility
values range from 0 to 100.

Food can be grown in any kind of sector although agribusinesses  are  able  to
grow more food with fewer workers.

Every sector produces a base level of food according to the following:

  The amount of food that the sector can grow in one time unit is:

     fertility * 0.002

  The amount of food that can be harvested in one time unit is:

     (civilians + military / 5) * 0.002

  i.e.  one  civilian can harvest four times the amount that he/she eats while
  one military can harvest 4/5 of the amount that she/he eats.

  Note that this means that although a sector with a fertility of 40 can  grow
  enough food to support 160 people at least 10 of them must be civilians.  In
  fact, any combination of civilians and military that meets the following two
  criteria will be self-sufficient:

     civilians + military <= 4 * fertility (amount that grows)

     military <= 15 * civilians (amount that gets harvested)

In  an agribusiness an additional amount of food can be grown.  That amount is
calculated by the following:

  An efficiency factor (effact) takes into account the state of repair of  the
  agribusiness  itself  (sector efficiency, effic) and the technology level of
  your farmers (the national technology level, tlev):

     effact = (effic * (tlev + 10)) / (100 * (tlev + 20))

  The amount of additional food that the sector produces in one time unit is:

     (civilians + military / 5) * effact * fertility / 1000.

  Thus, a 100% agribusiness with a fertility of 50 and an educational level of
  10  has an efficiency factor is 2/3; one civilian can harvest 0.033 units of
  food per time unit beyond the food normally produced in that  sector.   This
  extra  amount  is enough to support 33-three other people while one military
  can harvest 0.0066, enough to feed 13 other people.

  The amount of food cultivated by 10 civilians in 10 time  units  in  a  100%
  agribusiness are:

              |  EDUCATION LEVEL  |
              |  0  |  10  |  100 |
        ------+-----+------+------+
        F  10 | 0.5 | 0.67 | 0.92 |
        E  ---+-----+------+------+
        R  50 | 2.5 | 3.33 | 4.58 |
        T  ---+-----+------+------+
        . 100 | 5.0 | 6.67 | 9.17 |
        ------+-----+------+------+

     SPECIAL  NOTE:  Residents of a sanctuary need no food to survive; thus no
     one ever starves in a sanctuary.

     On a ship the following applies:

       The amount of food that can be produced on a fishing boat in  one  time
       unit is:

          (civil * etus * fertil) / 10000;

       However, if the NEWFISH option is in use, the limit is:

          (civil * etus * fertil) / 1000;

       The  amount  of food that can be produced on any other ship in one time
       unit is:

          0

     Note that if a ship doesn't have enough food, it will try to draw it from
     supply sources (see info supply). If it still hasn't enough food, it will
     attempt to grab unneeded food from any land units it is carrying.

     Land units eat food as well, an amount based on the total number of mili-
     tary  in  the unit (this is the efficiency times the number of mil needed
     to build the unit). If a land unit doesn't have enough food, it will  try
     to  draw  it  from  supply sources (see info supply). If it still doesn't
     have enough, and it is on a ship, it will attempt to get  food  from  the
     ship.

     The presence of food also affects the birthrate in Empire; if there is no
     food in a sector no babies will be born.  A baby consumes  0.3  units  of
     food  in  growing  to adulthood.  However, babies are only allowed to eat
     half the food in a sector.  Thus if a sector could produce 25 new  civil-
     ians  but  only  has 2 spare units of food, (after the current population
     has eaten), only three babies will be born and one unit of food  will  be
     left.

NAME
   Guerrilla - Guerrilla warfare

Level: Expert

Guerrillas are created in several ways; when a sector is captured by an enemy,
or when civilians riot for one reason or another  (starvation,  no  happiness,
etc).

Guerrillas have a generally detrimental effect on the well-being of your coun-
try.  Depending on the amount of military in the sector they infest, they will
either  attack the military there (but only if they have a good chance of win-
ning), blow up things (lowering sector efficiency), or, if they are too  badly
outnumbered, they will try and move to a different sector.

If  there  are  no military in the infested sector at the end of the update to
break up guerrilla recruitment drives, your civilians'  loyalty  will  suffer.
If the sector is only occupied -- not completely owned by you, that is -- then
it will revert back to the old owner, renouncing the conqueror  and  returning
to  their  old  allegiance.   The guerrillas will then move on to convert more
sectors.  Particular guerrilla bands will fight to the  death,  or  until  you
dissolve in disgust.

Guerrillas  will  attempt to recruit new followers from semi-loyal sectors and
from the uncompensated worker population.  Loyal civilians will  resist  these
recruiting  drives,  but uncompensated workers will always flock to the banner
of the guerrilla warrior.

The renowned guerrilla fighter Colonel (later Captain) Batguano gave a talk to
the  special  forces, which was later made into an Armed Forces Technical Man-
ual.  In it he states,

The first thing you learn is that the che  are  hardier
than cockroaches, eat like birds, and are simply invul-
nerable to gunfire and napalm.  They hide in  the  sew-
ers.   There are two ways to handle the guerrilla prob-
lem; one way requires high yield  fusion  weapons,  and
then  they  only die when everything else in the sector
is  destroyed.   Unfortunately,  collateral  damage  to
civilian assets renders this strategy negatory ... Col.
Batguano then launches into a tirade against the wimpy-
assed liberals which interfere with the proper guerril-
la suppression techniques ...  Almost every fully-popu-
lated  area we moved into had a few dozen of the little
monsters, and troop levels of 50-100  per  sector  were
found  to adequately pacify the region.  Of course, de-
populating the area prior to takeover often had a salu-

You will be notified of the varying civil disturbances by production telegrams
showing a body count of guerrillas killed, a sector being subverted by revolu-
tionary propaganda, or a sector lost to guerrilla activities!

Land units present in a sector help to fight them, fighting without any multi-
plier, either offensive or defensive and without any fortification bonus.  Any
units  with  the security ability will also kill some che before anything else
is done (commando raids).

NAME
   Happiness - How happiness is calculated at the update

Level: Expert

Happiness  is required for countries which have any sort of technology or edu-
cation at all, with greater levels being  required  as  the  expectation  (and
tech/edu levels) of the populace increases.  A country with an unhappy popula-
tion can expect a decrease in the work of some sectors.

Also, the morale of your land units is determined by  the  happiness  of  your
people.  The  morale of a unit can be set by the player, but the minimum level
allowable is determined by happiness:
   75 - happiness

Thus, a nation with a happiness of 20 would have a  minimum  allowable  morale
level of 55%

The  nation  command  will display, among other things, your current happiness
level.

The procedure determining happiness level is exactly the same for happiness as
it is for education (see "info Education") except for the fact that "happiness
log base" is always 6.0 and "easy happiness" is always 5.0.  New happiness  is
averaged  with old happiness in the same way that education is averaged except
that happiness averaging has its own line in the "version" output:
  Happiness is averaged over 48 time units.

It has also been rumored that increasing  happiness  will  help  to  keep  the
rebels in check somewhat, but the exact results are sketchy at best.

NAME
   Hitchance - The chance of a projectile hitting its target

Level: Expert

This  page describes the chance of a mine, torpedo, ship anti-missile defense,
missile, or plane hitting its target.

Sea Mine hitchance
The chance of a ship hitting a mine at sea is (mines/(mines+20)). (For
example, with 20 mines, the chance of hitting one is 20/40 = 50%) The
damage is dependent upon the size of the ship and the spot that the
mine hits.  (see info Damage).

Land Mine Hitchance
The chance of a land unit hitting a land mine is mines/(mines+35).
(For example, with 20 mines, the chance of hitting one is 20/55 =
36%).  See info Damage to find out how much damage things take
from land mines.  Note that the chance of land units hitting land
mines is divided by 3 if the land units are accompanied by engineers.

When moving commodities (civs, mil, shells, etc) or transporting
planes, the chance is also dependent upon the weight being moved.
First the above chance is checked, and then a chance equal to (weight
/ 100) is checked.

Torpedo hitchance
The chance of a torpedo hitting its target is equal to:
  hitchance = 0.9/(range + 1)
where "range" is the range to the target.  If the visibility of the
ship firing is less than 6, then (5 - visibility) * 0.03 is added to
the hitchance.

Thus, the base chance of a sub hitting its target (before visibility
modification) is:

     Range   Chance
     0       90%
     1       45%
     2       30%
     3       22.5%
     4       18%
     5       15%

Ships anti-missile defense
If a ship has "anti-missile" defense capabiilty, then it will
intercept any marine missiles launched at ships within 1 sector of the
ship.  Only missiles belonging to a country you are "At War" with will
be intercepted.  Only ships which are at least 60% efficient will be
able to use their anti-missile defenses.  The chance of the ship
hitting the incoming missile it equal to:

  hitchance = gun * eff * tfact * 4.5 - (missile "def" value)
where
  gun = the number of guns the ship is allowed to carry
  eff = the efficiency of the shiip
  tfact = tech / (tech + 200)
where
  tech is the tech level that the ship was built at

Plane and missile hitchance
If the plane or missile is carrying a nuclear warhead or the target is
a sector, then the hitchance is 100%.  Otherwise, the following
procedure is used to calculate hitchance.

The formula for a plane or missile hitting its target depends on the
type of the target (ship, plane, land unit) and the "hardtarget" value
of the target (which represents how hard that target is to hit).

Ship:
  vis = the visibility of the ship (from 'show ship stats').
For a sub, we set vis = visibility * 4.
If the ship is at sea, then:
  hardtarget = (eff of ship) * (20 + speed/2 - vis)
otherwise:
  hardtarget = (eff of ship) * (20 - vis)
The hardtarget of a fleet is the hardtarget if the "easiest" target in
the fleet.

Land unit:
  hardtarget = (efficiency) * (10 + (sector defense) * 2 + speed/2 - vis)
The hardtarget of an army is the hardtarget of the "easiest" target in
the army.

Plane:
If the plane is in the air (satellite, icbm), then
  hardtarget = the "def" value of the plane.
otherwise if the plane is on the ground:
  hardtarget = 0

Once we have calculated the "hardtarget" value of the target, then the
chance of a plane or missile hitting its target is equal to:

  hitchance = acc - hardtarget

where
  acc = (efficiency) * (1 - 0.1 * tfact) * (1 - placc/100)
where
  tfact = (pltech - mintech)/(pltech - mintech/2)
where
  pltech = tech level of plane
  mintech = min tech level required to build plane
and
  placc = plane accuracy
and if the target is a ship and the plane is an ASW plane, then
  placc = placc - 20
and if the target is a ship and the plane does not have tactical capability
  placc = placc + 35

Lastly we smooth out the bottom end of the hitchance curve.  If
hitchance is less than 20, then it is "belled up" using the following
curve:
  hitchance = 5 + 300 / (40 - hitchance).

On the other hand, you can just find out the hitchance by pinbombing
or launching a missile--the hitchance is always printed!  :-)

NAME
   Infrastructure - Making your sectors better

Level: Basic

INFRASTRUCTURE

The  infrastructure  of  your sectors determines how well your sectors defend,
and how well you can move commodities and vehicles (land units)  through  your
sectors.

You  can  improve  the  "road", "rail" and "defense" efficiency of all of your
sectors, given that you have the  correct  commodities,  enough  mobility  and
enough money.

The  "road"  infrastructure  determines how well (i.e. the mobility cost) com-
modities and non-train vehicles travelling through your  sector  are  able  to
move at both distribution time and while you are moving them by hand.

The  "rail" infrastructure determines how well (i.e. the mobility cost) trains
are able to move through your sectors.

The "defense" infrastructure determines how well  (i.e.  the  defense  factor)
your  sector  defends  itself.   There is a maximum amount that the sector may
obtain.  Use the "show sect stats" to see what the maximum values are.

So, what you can do, by using up some commodities, mobility and  cash,  is  to
create  a  pseudo-highway  network through non-highway sectors.  You can still
create highway sectors for just the designation fee  of  the  sector,  but  it
costs  you  a whole sector to use it.  This is a trade-off for both being able
to use the sector and still move things through it at a reasonable cost.

When you "improve" the infrastructure of your sectors, you  are  improving  on
the  efficiency  of  part  of  that sector (either road, rail or defense.)  By
improving it, it's statistics get better.  For roads  and  rails,  that  means
that  the  mobility  cost  to move through goes down.  For defense, that means
that you are building up the "defenses" of  the  sector  towards  the  maximum
allowed (see "show sector stats" for the maximum values.)

Since infrastructure is on an efficiency basis, it takes damage just like reg-
ular efficiency.  So, when a sector is shelled or bombed,  the  infrastructure
there is damaged in an efficiency based manner.

Infrastructure  is  also  not affected by rebuilding the sector.  So, once you
build infrastructure, it stays in place until the sector is  damaged  in  some
way.

Use  the  "sinfrastructure"  command to see what the current infrastructure of
your country looks like.

Use the "improve" command to improve the infrastructure of your sectors.

To find out the required amounts of materials, mobility,  and  money  use  the
"show sect build" command.

Also, defensive infrastructure is not always improvable.  See the version info
to see if the DEFENSE_INFRA option is enabled or not.  If it is  not  enabled,
the  defense infrastructure of the sector is always the same as the efficiency
of the sector.  If it is enabled, you must improve your sectors defensive val-
ues using the "improve" command.

   Innards - Some details about the inner workings of the server

Level: Expert

Much of this file is now out-of-date.  Correct information may be found in the
files Update-sequence and build.

This topic contains fairly nitty-gritty descriptions of some of the underlying
mechanisms  in  the  Empire  system.  It is not meant for the weak-of-heart or
casual reader.  (And it's usually out of date.)

Sector Updates

Several characteristics of the Empire game are dependent on sector updates  --
mobility, efficiency, mining of ore, generation of production units, etc.

An understanding of the calculations involved is often helpful in planning the
timing of various actions and although it is unlikely that this description is
strictly up to date, it should provide a feel for the overall philosophy.

All  commodities  in  a sector are kept as short integers.  The program cannot
have negative commodity values, so the theoretical capacity  of  a  sector  is
32767,  while in practice it is actually 9999 (for formatting reasons).  While
it is possible to move more commodities than 9999 into sectors, production  of
commodities  will  not go above the level of 999.  So, an update that produces
450 units of iron in a sector that already has 800 units can at most  add  199
units.

Here is an approximate description of the algorithm that is called whenever an
update occurs:

Variables used are:
     etus  the # of Empire time units in this update
      civ  civilians in the sector
      mil  military in the sector
       uw  uncompensated workers in the sector
    desig  designation of the sector
    effic  efficiency of the sector
    miner  iron mineral content of the sector
     gold  gold mineral content of the sector
  t_level  technology level of the country
  r_level  research level of the country
  p_stage  plague stage in the sector
   p_time  plague stage duration
workforce  an intermediate variable that represents work potential
     work  the amount of work done in the sector

Parameters used are (see the version command for actual values):
s_p_etu  seconds per Empire time unit
 fgrate  the food growth rate
 fcrate  the food cultivation rate
eatrate  how much food people eat
 obrate  birth rate
uwbrate  uncompensated worker birth rate
babyeat  how much babies eat growing up
bankint  bank interest rate in $/bar

workforce = (civ*100/sector work + uw + mil / 5.) / 100.
If workforce = 0 go away and don't update anything

/* increase sector efficiency */
If the weather is good enough for construction and we're not broke then
  effic becomes effic + work (if possible) and costs $1 for each
  percentage point gained.
Otherwise charge the $1 for each percentage point that would have been
  gained, (pay for workers to play cards).

/* grow some food */
Set dd = etu * sector_fertility * fgrate
    (this is the amount of food that can be grown in etu time units)
Set dtemp = work * 100. * fcrate
    (this is the amount of food that the people there can harvest)
If (dtemp < dd)     (if there aren't enough people to harvest it all)
    set dd = dtemp
Set foodtmp to the amount of food in the sector plus dd

/* feed the masses */
If desig is sanctuary then
    set dd equal to 0.
Else
    set dd equal to etu * (civ + mil) * eatrate
     (this is the amount of food the people need to eat)
If (dd > foodtmp) then some people will starve
    figure out what percentage of the population can be fed,
    and kill the rest (up to a maximum of 1/2 the populace)
    set food = 0
Otherwise
    set food = foodtmp - dd (with a maximum of 999)

/* population growth */
set q = etu * civ * obrate
     the number of births possible in other sectors
If q is bigger than food / (2 * babyeat) set q to food / (2 * babyeat)
     food available to mature this many babies into civilians
If q is bigger than 999 - civ set q to 999 - civ
     enough room for that many
Set food = food - q * babyeat
Set civ = civ + q

/* mobility */
Add etu to mobil (to a max of 127)

/* pay taxes */
Collect the taxes, pay the military
    civ_tax = (int) (.5 + (civs * eff * etu * civtaxrate / 100.));
    if (conquered) civ_tax /= 4.;
    uw_tax  = (int) (.5 + (uws  * eff * etu * uwtaxrate  / 100.));
    mil_pay = (int) (mil * etu * milpayrate);

    nat_money -= mil_pay
    nat_money += civ_tax + uw_tax

/* plague */
If p_stage = third kill off a bunch of people,
   alert the owner and the news and decrement p_time by dt.
   If p_time <= 0 set p_stage = zero (plague has burned itself out).
If p_stage = second report
   to the owner and the news and decrement p_time by dt.
   If p_time <= 0 set p_stage = third
      and randomly reset p_time in the range of etu_per_update to
      (etu_per_update * 2).
If p_stage = first decrement p_time by dt.
   If p_time <= 0 set p_stage = second
      and randomly reset p_time in the range of etu_per_update to
      (etu_per_update * 2).
If p_stage = zero and a random number in the range 0-99
   is less than the figure generated by the equation in info plague
   then set p_stage = first
   and set p_time to a random number in the range of etu_per_update to
   (etu_per_update * 2).

/* delivery & distribution */
If anything is being delivered from this sector and there is
more of it than the delivery threshold (always a multiple of 8)
and the country is not broke
    deliver as much of the excess as mobility allows.
    If plague_stage is second (the infectious stage)
     set plague_stage and plague_time in the destination sector.
If there is a distribution threshold for this sector, and
if the sector isn't at this threshold,
     import or export as necessary from the distribution warehouse
     the number of commodities, mobility permitting.

/* production */
If effic is less than 60 skip the rest.

If desig is bank then accrue  etu * bankint  interest per gold bar
If desig is capital pay etu * $1 for government salaries
If desig is enlistment sector, then convert civilians to military
        newmil = (etu * (mil + 10) * 0.05);
        nat_money -= newmil * 3;
If this sector produces something (mines, research labs, etc.)
      calculate how much can be produced (see info Products)
          (Note that the amount that can be produced is limited by work)
      produce it
      pay for it (money, iron, gold mineral, oil, etc.)

Several points are noteworthy:

+o The work done in a sector (ore dug up, efficiency growth, population growth,
products generated, etc) is dependent on the product of time since last update
and work force (work above) while the accumulation of mobility is  independent
of work force.

+o  If the population of a sector is very low it may never generate any work at
all due to conversion to integer truncation.

Ship Updates

Ships are also updated only when accessed however the  mechanism  is  simpler.
The  only  characteristics  that are changed by ship updates are the mobility,
the efficiency, (if less than 100%).  the food, (and  therefore  the  crew  if
starvation  occurs),  the  amount  of  oil, and plague status, (which can also
change the size of the crew).

The algorithm is essentially:
   add etu to mobility (with a maximum of 127)
   add etu to efficiency (with a maximum of 100)
   add etu * civil * sector_oil / 10000. to oil if ship type is oil derrick
   add etu * civil * sector_fertil / 10000. to food if ship type is fishing boat
   feed the crew and passengers
       starve a few if not enough food
   check for plague progress,
       (the same as in sectors except each stage lasts twice as long on a ship)

Bureaucratic Time Units

There is one further update that is not handled in the sector update  routine;
that  is  the update of bureaucracy time units (BTU's).  These are the numbers
printed in brackets before the command prompt.  Most commands given use BTU's,
some use 1, some use 2 and some use more, making BTU's a vital commodity.  The
generation of BTU's is dependent on the efficiency and the work force  in  the
capital sector.  (see info BTU).

NAME
   Interception - How plane interdiction works

Level: Expert

Each  time  an enemy plane (i.e. a plane owned by a country that your are HOS-
TILE to or worse) flies into over a sector you own, planes you have  with  the
intercept ability will intercept them if:

   a) The incoming plane is not stealthy, or is detected.
   b) The sector is within 1/2 the interceptor's range (as modified
   by rangeedit)
   b) They have mobility
   c) Their efficiency is 40 or more
   d) They are at an appropriate place:
        1) planes without VTOL ability must be at an airport that
             is at least 60% efficient.

        2) planes on ships may only fly if the ship can operate
             that kind of aircraft.

   e) There is petrol there equal to 1/2 the plane's fuel rating.
        (rounded down)

Before planes scramble to intercept incoming planes, any SAMs in range will be
launched.  One SAM is launched at each incoming plane that cost at least $1000
to build.  See below for the damage that the SAM does to the plane it hits.

Enemy  planes  will  be  intercepted by up to 1 more interceptor, i.e. 1 plane
will be intercepted by 2 (if available), 2 by 3, 3 by 4, etc. The highest num-
bered  planes  intercept  first. Incoming missiles will only be intercepted by
ABM's

Once the roster of attackers  &  intercepters  is  determined,  attackers  and
interceptors  dogfight.  First escorts & interceptors fight, then planes being
escorted & surviving non-aborted interceptors.

First, an attacker and a defender are chosen, then each  plane  on  each  list
fights once.

Combat values

The  attacker's  combat  value  is  calculated  by adding up his planes attack
value, and modifying it for efficiency, bomb-load,  and  stealth.  The  attack
value  of  the plane is multiplied times the plane's efficiency, but cannot go
below 1/2 of the plane-type's base value (as shown by show plane stats).   (If
the  plane's  attack  value  is 0, the defensive value is used instead, with a
minimum of 1/2 the plane- type's defensive value)

Two is subtracted if the attacking plane is carrying bombs.

If the plane is stealthy, stealth%/25 is added.

The defender's value is calculated in the same way, except that the  defensive
value is always used.

Odds

Next, an odds ratio is calculated: (att/(def+att))*100.

Combat Intensity

Then, a combat intensity is rolled: (d20+d20+d20+d20)

Combat  For  each point of combat intensity (or until both planes are dead), a
d100 is rolled. If the value is less than the odds, the defender takes a casu-
alty, otherwise the attacker takes a casualty.

Once  all  combat  rolls have been made, the attacker and defender are checked
for aborting. If a plane is damaged below 80%, then it will have a  chance  of
aborting.   The  chance  to abort is (100-plane eff). (Example: a plane at 70%
has a 30% chance to abort.

Missiles intercepting die after the combat is done.
Example

Suppose that a fighter 2 (30% efficient, tech 154, attack value 7) is conduct-
ing  a  recon  mission.  As  it enters an enemy controlled sector, a fighter 1
(100% efficient, tech 131, defense  value  4)  rises  up  to  fight  it.   The
attacker's combat value is calculated:

   1) 7 * (30/100) = 2.1 = 2

   2) 2 is less than 1/2 the base attack value of an f2 (6), so the value
   is changed to 3

   3) The attacking plane is not stealthy. No modifier.

   4) The attacking plane is not carrying bombs. No modifier.

The defender's defense value, calculated similarly, is 4.

The odds ratio is (3/(3+4)) = .429 = 43%

The  intensity  is  randomly  determined  to be 30. A d100 is rolled 30 times.
Each time that is 43 or less, the defender takes a hit. Each time it is 44  or
more, the attacker takes a hit.

In  our  example,  the attacker takes 17, the defender 13, leaving them at 13%
and 87% efficiency, respectively. The attacker has an 87% chance to abort, and
the  defender  a 13%. If neither aborts, the attacker flies on. If both abort,
the mission is over. If only the defender aborts, the attacker will fly on  to
the  next sector in his flight path (perhaps to have combat again) If only the
attacker aborts, the defender flies home with the  knowledge  of  a  job  well
done.

ABM's  ABM's  do  not  use  the  normal combat procedure. They simply have a %
chance of destroying an incoming warhead equal to their defensive value.

If you have land units in the enemy plane's target  sector,  your  plane  will
intercept  the  enemy  planes  AGAIN.  If  you have non-sub ships in the enemy
plane's target sector, your planes will intercept them yet again. If  you  own
the  target  sector,  and have ships & units there, your planes will therefore
intercept them a total of three times in that sector. Note that a 'target sec-
tor'  is a sector that is the target of a bombing or para mission. Merely hav-
ing ships in a sector will not cause interception of planes flying over.

NAME
   Land-units - How to use land units

Level: Basic

Land  units  are organized collections of mil (militia). They are considerably
more effective and cost-efficient than militia, and have many extra abilities.
With  the  addition  of  land units, mil are now more or less considered to be
militia instead of military, and are less important.

The way that military are incorporated into units are that the mil  are  load-
able commodities of the unit.  The offensive or defensive

Commands  for  land  units are generally similar to those of planes/ships, and
will usually start with 'l'.

Land unit characteristics

Land units have some characteristics of  both  ships  and  planes,  plus  some
unique  ones. Like both ships & planes, they have efficiency & mobility.  Like
ships, they can carry cargo, may have/use fuel, and may be able to  fire  guns
at  distant targets. Like planes, they have attack and defense values, and may
be able to act automatically to defend your country.  Let's look at a  typical
land unit:

   [##:##] Command: land *

      # unit type             x,y   a  eff mil fort  mu  fd tech retr rd xl ship
      0 inf   infantry        8,0      96% 100    0  93  24    0  42%  1  0
   1 unit

This  land  unit  is an infantry unit, located at 8,0. In many games, you will
start with 1-2 basic land units of this type. Some of the things about it  are
familiar. It is 96% efficient, has 93 mobility units, carries 1 food, no fuel,
and is tech 0 and currently contains 100 mi. It carries 0 extra-light  planes,
and  is  not  on  a  ship. The 'a' stands for army, and is just like fleets or
wings, i.e. a way of grouping your units. (See info army for more information)
Fort  is  the  level  of  fortification  of  the  land  unit.  The  higher the
fortification, the harder the unit is to hurt.

The 'retr' stands for retreat percentage. This land unit  must  begin  rolling
morale  checks  in combat whenever its efficiency goes below 75%. This is user
settable in a range determined by the happiness of  the  owning  country.  The
happier  your  people  are, the more determinedly they fight. If, on the other
hand, you want the unit to retreat easily, you can set this to  100%  or  some
other  high  number.  (For  information  on setting this, see info morale. For
information on morale checks, see info attack)

The 'rd' field is referred to as the unit's 'reaction radius', and is the dis-
tance  to  which  the unit can react to defend your country.  Basically, if an
enemy attacks a sector close enough to the unit, it will go to the  threatened
sector and fight, like a plane intercepting. If it survives the attack without
failing a morale check, it will return to the sector  it  started  from,  just
like  a  plane would. (For more information on reacting and morale checks, see
info attack) Just as you can use rangeedit to change the range of your  planes
and  control  how  far  away they'll intercept, so you can change the reaction
radius with lrangedit. Units with a base reaction radius of 0, or those  whose
radius you have set to 0, will not react.

Cargo

Each land unit can carry cargo. The cargo display for land units is very simi-
lar to that of ships, and is gotten with the lcargo command.

   [##:##] Command: lcargo *

   lnd# unit type     x,y    a   eff  sh gun pet irn dst bar oil lcm hcm rad
      0 infantry      8,0        96%   0   0   0   0   0   0   0   0   0   0
   1 unit

The land unit is not carrying anything. Potentially, land units can carry  any
of the commodities listed above. Unlike ships, they cannot carry mil, civs, or
uw's. Land units are loaded and unloaded using the lload command, which  works
pretty  much  like the load command for ships. (See info lload) Units on ships
can transfer supplies to/from the ships with the ltend command.

HQ's & Building land units

Like planes and ships, land units are  built  in  special  sectors.  For  land
units,  the  sector  is  the  headquarters  sectors, designation !. Like other
units, they may require hcms and lcms, and will generally require money.

Some land units may require guns to build. All this info can  be  gotten  with
the show command.

   [##:##] Command: show land build

                             lcm hcm guns avail tech  $
   inf   infantry             10   5    0    40    0  $500

The  infantry  unit  takes  a  total of 10 lcms, 5 hcms, and  0 guns to build.
Like ships and planes, units are built at a lower percentage, and 'grow' up to
100%,  and  any  unit  with an efficiency of less than the build percentage is
dead. For land units, this minimum efficiency is 10%.  The build  requirements
for  land  units,  like  those  listed  above,  are for a 100% unit. Thus, the
infantr1 would require 1 lcm and .5  hcms  (Fractional  amounts  are  randomly
rounded...  i.e.  .5 has a 50% chance of being 1 or 0. It'll all even out over
time)

When 'growing', land units require materials which must be present in the sec-
tor.  The  amount of growth is calculated in the same fashion as planes/ships.
Generally a land unit can grow by up to 2x the ETUs per update. (See the  ver-
sion command for exact maximums, as these are deity-settable) So, for example,
in a 32 ETU game, a land unit could possibly grow by 64% per update.  For  the
infantry  unit  shown above, this would require 6.4 lcms and 3.2 hcms.  If any
of these things aren't present in the sector, the unit won't gain  efficiency.

Repair of Land units

Ships  can  repair themselves in any sector, and can use work from their crew,
or from a harbor they are in. Planes can only be  repaired  in  airports,  and
only  use  work  from  the  airport. Land units can be repaired in HQ's, or in
fortresses, and use the work of the HQ or fort.  This  means  that  front-line
units in forts will repair themselves each update, assuming that the necessary
materials and work are available. They can also gain efficiency in other  sec-
tor types, but at a much reduced efficiency (1/3rd normal gain)

Land unit statistics

Each  land  unit  has certain vital statistics which show how it will operate.
These are obtainable from the show command:

   [##:##] Command: show land statistics

                                          s  v  s  r  f  a  d  a  a        x
                                          p  i  p  a  r  c  a  m  a  f  f  p
                             att def vul  d  s  y  d  g  c  m  m  f  c  u  l
   infantry                  1.0 1.5  60 23 15  2  1  0  0  0  0  0  0  0  0

The infantry unit has an attack multiplier of 1.0, and defensive multiplier of
1.5.  It  has a vulnerability rating of 60, a speed of 23, a visibility of 15,
spy value of 2, reaction radius maximum of 1, no firing range, no accuracy, no
firing  damage,  uses  no ammo, has no aa fire, doesn't carry of use fuel, and
can't carry extra-light planes.

When attacking, a unit's value is expressed in 'mil-equivalents', i.e. 1  mil-
eq  is  as  strong as 1 mil. To find a unit's attack value, find the number of
mil currently in it, and multiply by the attack multiplier and efficiency.  In
the   case  of  our  infantry  unit  the  unit  has  an  attack  value  of  96
(100*1.0*.96), and a defense value  of  144  (100*1.5.96).  Some  units,  like
tanks,  will  have  high  attack  multipliers, and medium defense multipliers.
Some, like most infantry, will be better at defending  than  attacking.  Some,
like artillery units, will be bad at both.

As  time  goes  on, and your tech increases, the stats of your land units will
get better.  This reflects the technological breakthroughs you  have  made  in
that you can now build better units of the same type.

The  vulnerability  of  a  unit  determines how easy it is to hurt the unit by
shelling it, bombing it, or when it encounters land mines. The lower the  vul-
nerability, the better. Values range from 1-100.

Spd  is  the relative speed of the land unit. Land units move by marching (see
info march), and use mob depending on their speed and  the  terrain  they  are
moving through. For more info and formulas, see info march.

Vis  is  the  visibility  of  the unit. This is a measure of how easy it is to
see/detect the unit. Lower is harder to see, and the numbers  can  range  from
1-100  or  so.  When a land unit tries to use the llookout command to look for
enemy land units/planes, its chances of success are  affected  by  the  target
units' visibility (see info llookout for more details).

Spy is the other side of the equation, i.e. how well can the unit find things?
A unit with a low spy won't be very good at locating other units, and won't be
able to report much when it encounters them in battle. A high-spy unit will be
able to use the llookout command with more chance of success, and will be able
to  more accurately report information about the units it runs into in battle.
(See info attack for information about intelligence reports) Units with  radar
capacity  also use their spy value to determine how far they can see. Spy val-
ues range from 0-127, with low numbers being most common.

Don't confuse this spy value with the "spy" capability of a unit.   See  "info
Spies" for more information.

Rad  is  the  maximum  reaction radius for the unit. When built, the unit will
have this as its reaction radius. If you change the reaction radius  by  using
the  lrangedit command, you will be able to select any value that is between 0
and the maximum.

Frg is the unit's firing range. The unit can fire as far as the frg,  modified
by  the  unit's  tech.  Accuracy  is  the unit's firing accuracy, and helps to
determine how much damage it will do, along with the dam  of  the  unit.  When
firing  at  sectors,  damage  is  based  solely  on the damage. When firing in
defense of a sector, or firing at ships, damage is based on both acc and  dam.
(See info fire for more information)

Ammo  is the number of shells a land unit uses every time it fires or partici-
pates in combat. If the unit does not have enough shells when  firing,  damage
will be reduced proportionately. If a unit does not have enough shells in com-
bat, it will be out of supply, and have its combat strength cut in half.  (See
info  supply and info attack for information on supply and how it affects com-
bat.

Aaf is the unit's anti-aircraft fire value. The higher  the  value,  the  more
damage the unit will do to planes flying overhead.

Fc/fu  are the unit's fuel capacity and use. If the fc/fu are 0, the unit does
not need fuel to gain mobility. If the fc/fu are non-zero, the unit will  need
fuel  to  gain  mobility,  and will use fu fuel whenever it fights.  (See info
fuel for information on fuel)

Xpl is the number of extra-light planes the unit can carry. Planes can operate
from  a  land  unit  in  the  same fashion as if it were a carrier.  Normally,
extra-light planes are SAMs, so units can carry  SAMs  for  air-defense.  This
particular unit can't carry any.

Land unit capabilities

There  are  many  different capabilities that land units may have. They may be
seen with the show command:

   [##:##] Command: show land capability

                             capabilities
   infantry                  5f light assault

The command shows the cargos the unit can carry (5 food in this case), and its
abilities. See info Unit-types for a complete description of the various capa-
bilities.

Moving

Land units move with the march command, which is pretty identical to the navi-
gate  command.  Marching  units  can run into land-mines, be interdicted, etc.
See info march for more info. See info mission for  information  on  interdic-
tion.

Units & ships

Each  type  of  ship  is rated on the number of land units it can carry.  Land
units that are 'light' can be loaded onto ships using the normal load  command
(see info load). Units that also have the 'assault' ability (see info show and
info Unit-types for explanations of abilities) can be used in assaulting  sec-
tors. (See info assault).

Supply

Units  need  supplies  in  order  to  attack.  Each update, and each time they
attack, units will attempt to draw supplies. See  info  supply.   Really,  I'm
serious.  If  you don't read info supply, you'll die a horrible death. I'm not
kidding.

Fortification

Land units are able to fortify themselves to better resist damage. Each  point
of  mobility  spent  increases  the  fortification level by 1, up to a maximum
equal to the maximum mobility of a land unit. A fully fortified unit takes one
half the normal amount of damage. Fortification is lost when the unit moves or
retreats. (Note that a reacting defending unit can have a fortification value.
This is an abstraction) Read info fortify for more details.

Looking

Land  units  can use llookout to look around. This command is analogous to the
look command used by ships. When llooking, land units have a  chance  to  spot
other  land units and also planes. Recon units tend to have better spy values,
and so are better at this.  (See info show and info  Unit-types  to  find  out
more about recon units).

Radar

Some  units can use the lradar command. This command works like the radar com-
mand. Radar range is determined by the unit's spy value.  (See info  show  and
info Unit-types to find out more about radar units).

Engineers

Some  land  units  have  the 'engineering' ability. These units can do several
things. Engineers are the only units that can lay  land-mines,  and  the  only
units  that  can  sweep them when moving (like a minesweeper). Attacking engi-
neers also halve the defender's mine bonus. Engineers can also  use  the  work
command,  which  allows  them to raise sector efficiency. (See info work) They
also tend to be quite expensive.

Attacking & defending

Info attack has a complete treatment of this, but I will summarize here.  When
you  decide  to  attack a sector, you can use mil and units from adjacent sec-
tors. The attack value of your forces is the combined  attack  values  of  all
attacking  land units, plus the number of mil coming in from adjacent sectors.

The defense value is equal to the  mil  in  the  defending  sector,  plus  the
defense values of any defending units in the sector, as well as any that react
and move there.

Friendly ships/forts/artillery units/planes can  contribute  support.  Support
starts  at  1.0.  Each  friendly ship/fort/artillery unit/ plane that can help
adds its damage/100 to the support. For example, if you were attacking a  sec-
tor,  and  a friendly battleship was close enough to fire there, it could sup-
port you. If it would normally do 23% damage when firing, it  would  add  +.23
support, making your support number 1.23. The enemy also gets support from all
his stuff.

When all support is totaled,  the  attacker  strength  is  multiplied  by  the
attacker's  support  to  get the total attacker strength. The defender's total
strength is determined similarly. Both sides have their strength  modified  by
the  terrain. (show sector stats will show the defensive value of a sector) He
can also get support by having mine-fields in the sector (see info  lmine  and
info  attack  for more information). Planes support only if assigned to a sup-
port mission. See info mission for information on support missions.

Combat is done fairly normally, with a series of rolls for attacker/  defender
casualties,  until  one side is dead or retreats. Land units take damage after
all mil on their side are dead, and each 'hit' on a land unit does 1 mil  dam-
age.  (Therefore, a unit that takes 100 mil to build would take 1% damage when
it suffers a casualty. A unit that takes 50 mil would take  2%,  etc)  When  a
land unit's level of damage taken in a battle reaches it's 'retreat level', it
must begin taking morale checks. When it fails one, it will retreat.  Retreat-
ing attacking units go back to the sector they came from. Defending units will
attempt to retreat to an adjacent owned sector. If there are  none,  the  unit
will take extra damage and continue fighting.

If the attacker wins, he captures the sector, and his mil/units will move into
the sector if he ordered that. If the defender wins a combat, his units in the
sector  stay  there.  His  reacting defending units that did not fail a morale
check return to their starting point.  Defending  units  who  started  in  the
sector stay in the sector.

In both cases, retreated units end up in the sector they retreated to.

Units and retreating

Ships  can  use the retreat command to specify when and how they will run away
from trouble. Land units use a similar command lretreat to do the same  thing.
See info lretreat for more details.

NAME
   Maintenance - The cost to maintain ships, planes, and land units.

Level: Expert

During  each  update,  nations  must  pay  to  maintain their units, ships and
planes.

The cost to maintain a ship, or land-unit is:

        .001 * cost of thing * ETUs/update

The cost to maintain a plane is:

        .001 * cost of thing * ETUs/update + 5 * mil_cost * crew

Note that this cost can be changed by the deity.

Also note that if you have purchased high-tech items, and your tech is not  at
least 85% of the item's tech, you are charged double to maintain the item.

Also  note  that  engineering land units costs 3 times what normal units cost,
after the tech is figured in.

If you can not afford to pay maintenance costs or you choose not to  pay  them
(see  info budget) then your unit will lose ETU/5 points of efficiency.  Thus,
if you were playing in a 60 ETU game, and you did  not  pay  your  maintenance
costs for a 50% frigate, then the frigate would drop to 38% efficiency.

NAME
   Mobility - How much mobility stuff costs

Level: Expert

Mobility represents the amount of time and energy it takes to do
something.  In "Real Life" a ground offensive takes hours.  In Empire,
it takes less than a second.  Now the way Empire *could* work would be
for you to give your troops "orders" and then wait a "realistic"
amount of time for them to carry these orders out.  But who wants to
type "nav 15 yh" and then wait 30 minutes for the ship to get there?
Certainly not you!  That's why mobility was invented.  Every update,
all of your units and sectors get more mobility, and that means that
enough time has passed for you to be able to do more stuff!

In Empire, four things have mobility: sectors, ships, planes, and land
units.  You can see how much mobility each of these gets every update
in the output of the "version" command:
                                Sectors Ships   Planes  Units
Maximum mobility                127     127     127     127
Max mob gain per update         60      120     90      90

If the mobility cost for something is a fraction, for example 2.4,
then there will be a percentage chance that the actual cost is rounded
up or down.  In our example, there would be a 60% chance that 2.4 is
rounded down to 2 and a 40% chance that it is rounded up to 3.

-- Land Units --
Land units are charged mobility for the following actions:

1. Fighting
See "info Attack" for the mobility cost to attack.

2. Fighting rebels
For each 2 points of efficiency a land unit looses fighting rebels at
the update, it looses one point of mobility.

3. Fortification
To fortify ("dig in") a land unit costs one point of mobility per
point of fortification.

4. Converting civs
Security units are charged 10 mobility every time civs are converted
in a sector they are in.

5. Laying mines
A land unit is charged one point of mobility for every land mine laid.

6. Work
The increase in efficiency depends on mobility used. It costs a 100%
efficient land unit 6 mobility to raise a sector 1% efficiency.  Less
efficient land units are charged proportionally higher amounts of
mobility.  For example, a 50% land unit would be charged 12 mobility
to raise the efficiency of a sector by 1%.

7. Supply
When supply is drawn from a supply unit, that unit pays the mobility
cost to move the goods to the destination sector.  That cost is the
same as it would cost the sector to move the goods using the "move"
command.

8. Marching, reacting or retreating
The mobility cost for a land unit to march, react or retreat is:
  (path cost) * 5 * 480 / (unit speed)
See "Path Cost" below for the path cost formula.  Note that reactung
land units only pay mobility to move "to" the attacked sector; they
return to their start sector for free.  Land units on "reserve"
mission only pay half the mobility cost to react.

Note that the efficiency of a land unit does not affect the mobility
costs it pays to march, unless the unit is a supply unit.  Then the
mobility costs are proportional to the efficiency of the unit.

9. Shell damage
When a land unit is shelled, its mobility goes down in exactly the
same way that its efficiency goes down (see "info Damage").

-- Planes --
Plane mobility can never go below -32.  Planes are charged mobility
for the following:

1. Air combat
For every two points of damage the plane takes from air combat, the
plane looses one point of mobility.

2. Launching satellites
A satellite is charged one point of mobility for each sector it passes
over in its launch trajectory.

3. Flying
The mobility cost for a plane to fly is:
  5 + (flight cost) * (distance flown) / (max distance plane can fly)

For excorts and interceptors, the flight cost is:
  10 / (plane efficiency)
For all other flights, the flight cost is:
  20 / (plane effciiency)
For planes flying on an air defense mission, this cost is cut in half.

4. Land mine, pinbombing, a-sat, and nuclear damage
A land mine, pinpoint bomb, anti-sat missile or nuclear detonation
will damage the mobility of the plane in exactly the same way that the
efficiency of the plane is damaged (see "info Damage").

-- Ships --
Ships are charged mobility for the following:

1. Firing a shell
The mobility cost to fire a shell is 15, unless the NOMOBCOST option
is enabled in which case ships are charged nothing.

2. Firing a torpedo
The cost for a ship to fire a torpedo is one half of the cost for it
to move one sector.

3. Boarding a ship from a ship
See "info Attack" for the mobility cost to board a ship from a ship.

4. Navigating and retreating
The mobility cost for a ship to navigate or retreat is:
  (sectors travelled) * 480 / (ship speed)
where
  ship speed = (base speed) * (1 + (tech factor))
  base speed = max(0.01, efficiency * speed)
  tech factor = (50 + tech) / (200 + tech)

5. Shell damage
When a ship is shelled, its mobility goes down in exactly the same way
that its efficiency goes down (see "info Damage").

-- Sectors --
Sectors are charged mobility for the following actions:

1. Converting civs
Each civ converted costs 0.2 mobility.

2. Shooting civs & uws
The mobility cost to shoot civs or uws is
  (number shot + 4) / 5

3. Enlisting mil
The mobility cost for enlisting mil depends on what fraction of the
civs present you are enlisting:
  (new mobility) = (old mobility) * (1 - newmil / (starv civs))

4. Fighting
See "info Attack" for the mobility cost of attacking.

5. Moving commodities
Sectors move commodities in the "move" and "explore" commands, when
"supply" is drawn from them, and when they "deliver" and "distribute"
at the update.

Mobility is used from the source sector when moving.  Mobility used is
a factor of the commodity involved, the amount of the commodity, the
types of the sector and dist sector, the efficiency of both, and the
cost of the path to the destination sector.  When the move is
finished, move reports the total mobility used, and the amount of
mobility left in the sector.

The exact formula is:
  mob cost = (amount) * (weight) * (path cost) / (source packing bonus)

If the movement happened at the update, then the cost is:
  delivery cost = (mob cost) / 4
  distribute cost = (mob cost) / (10 * (destination packing bonus))

Weight
Each commodity has a weight:
  bar        50
  gun        10
  rad         8
  dust        5
  uw          2
  other       1

Packing Bonus
Some sectors are better at moving certain commodities than
others. This ability is known as their packing bonus. These sectors
only get these bonuses for moving items "from" them--not for moving
items "to" them. If the sector is less than 60% efficient, it doesn't
get its packing bonus.  Here are the packing bonuses:
        warehouse   harbor   bank   city*
  mil          1        1      1      1
   uw          2        2      1      1
  civ          4        4      1     10
  bar          5        5      4      1
other         10       10      1      1

* Note that If the BIG_CITY option is enabled, then 'c' sectors stand
for 'city' sectors, they can hold 10x as many civs, and they get a 10x
packing bonus for moving civs.

Path Cost
The path cost is the cumulative mobility cost of moving through each
sector in the path. The cost to enter a sector is based on the
sector's type and efficiency. All sectors cost 0.4 to move into when
they have a 0% road factor, except for mountains which cost 5.0 at 0%.
The mobility cost to move into a sector goes down linearly as the
road efficiency increases.  This represents the construction of roads.

You can also build railways to make the moving of trains faster.  When
marching trains about, the rail factor is used.  Otherwise, the road
factor is used.

See "info improve" for more information on improving the efficiency
ratings of your sectors, and see "info sinfrastructure" for information
on showing the infrastructure of your sectors.

See "info Infrastructure" for more general information on Infrastructure.

Update mobility bonus
Commodities get moved at the update through delivery and distribution.
All goods moved this way get their mob cost divided by 4 for deliver,
and 10 for distribute.  Furthermore, commodities distributed into a
harbor or warehouse get the warehouse packing bonus (normally, packing
bonuses only apply for the type of the source sector and not the type
of the destination sector).  These two bonuses represent the fact that
moving goods through an established distribution network is more
efficient.

6. Transporting planes or nukes
The weight of a plane is lcm + 2*hcm.  The weight of a nuke is the
number of "lbs" it has (from "show nuke stats").

7. Shell damage
When a sector is shelled, its mobility goes down in exactly the same
way that efficiency goes down (see "info Damage").

Most  of  Empire  consists  of you moving something from one place to another.
The following table tells you which commands you use to move the kind of thing
that you want to move.

   nuke            plane       sector    disarm 

Note  that  in the case of load, lload, unload, tend, and lunload, the way you
specify whether you are moving a commodity, land unit or plane is by using the
word  "land" or "plane" instead of the commodity name in the  field.  If
 is "land" or "plane", then  is the unit or plane id.  So for exam-
ple, to load ship #1 with land unit #2, you would type:
   [##:##] Command: load land 1 2

NAME
   Nuke-types - Description of different kinds of nuclear weapons

Level: Expert

There  are  two  different  types of nuclear devices in Empire: fission bombs,
fusion bombs.  Both fission and fusion bombs perform  similarly,  with  fusion
bombs giving more bang for the buck.

In  general,  the only way to avoid damage by a nuclear detonation is to avoid
the area prior to and during actual detonation.  Hardening missiles (in silos)
is  the  only exception, and even that cannot protect from a direct hit by the
larger nuclear devices.

The details of the nuclear devices present in Empire can  be  seen  using  the
show command.  The meaning of the fields are as follows:

name  The nukes name.
 lcm  The amount of lcm needed to build the nuke
 hcm  The amount of hcm needed to build the nuke
 oil  The amount of crude oil required to build it.
 rad  The number of radioactive products required to build it.
tech  The minimum tech level required to construct the nuke.
   $  The cost of the nuke to construct.

The other fields given in the capabilities are as follows.

blst  The blast type of the nuke
 dam  The damage rating of the nuke
 lbs  the  weight  of  the  warhead, limiting missile and plane nuclear device
      carrying capacity.

As a guide (these numbers are subject to change):
   [##:##] Command: show nuke build

The larger the megatonnage, the more damage done by the weapon.   Effects  (as
in  the  real  world)  can  only  be  determined  by experimentation, although
research suggests that radioactivity left behind by  nuclear  detonations  may
have lasting effects.

NAME
   Plague - The Plague

Level: Expert

Plague  is  used  in  Empire to symbolize all forms of disease and is the only
health hazard associated with the Empire game, (ignoring it's effects  on  the
players).   The characteristics of plague are, therefore, a compromise of dis-
ease features (or bugs).

Note that if the NO_PLAGUE option is in use, a kindly deity has wiped out  the
plague for you. If not, worry about it.

All of the timelines below are based on a game with 32 ETU updates.

The  Empire  Plague  takes  between 96 and 189 time units to run its course on
land, (i.e., 2 to 4 days in any particular sector/ship/land unit if an  Empire
time unit is 1/2 and hour.)  In so doing the plague goes through three stages:

Stage I -- The gestation or incubation phase  in  which  no  symptoms  appear.
   Sectors or ships that are in this stage of the plague are indistinguishable
   from healthy sectors or ships.  This stage lasts 32 to 63 time units, (less
   than a day and a half).

Stage  II -- The infectious phase in which the symptoms first appear -- orange
   blotches on the face and hands, sometimes accompanied by  grey  stripes  on
   the  genitalia,  itching of the liver and spleen, an uncontrollable fear of
   ripe tomatoes, etc.  During this phase the plague is  extremely  communica-
   ble;  for  example, a simple delivery from an infectious sector will infect
   the destination sector.

Stage III -- The terminal phase in which people die, often in the act of flee-
   ing  from  (real  or  imagined) tomatoes.  The number of people that die is
   roughly inversely proportional to the research level of the  country  (plus
   100).

All three phases are of roughly equal average duration, (about 48 time periods
or 1 day).

Plague usually arises in countries with  high  technological  development  and
comparatively little medical research.  It arises specifically in sectors with
high population density and low efficiency.

Recently archaeologists have uncovered a treatise by a  Dr. M. Welby  entitled
Demographic considerations and the Empire Plague.  In part it states:

It  appeared  that our original hypothesis based on the
high percentage of Lumbagan Legionnaires among the  af-
flicted  had  led  us down a blind alley and that if we
were to solve this complex puzzle before the end of the
series in the spring a reference to the series of tests
leading to the mysterious Neilson Rating we would  have
to  turn to other disciplines for help.  It was only by
the merest lucky coincidence that as I drove  home  one
evening  ...   Dr.  Welby  relates  an amusing anecdote
about a Brownie Scout and the director of a film  enti-
tled  Close  Encounters of the Third Grade ...  leading
us to the following amazing formulation  of  the  rela-
tionship  between medical research, technology, popula-

   likelihood   civ + mil + uw   t_level + (iron + oil + rad * 2) / 10 + 100
       of     = -------------- * -------------------------------------------
     plague           999               r_level + effic + mobil + 100

Later formulations of this relationship show great similarity to his statement
(see info Innards).

Many  researchers have commented on the surprising lack of correlation between
food supply and plague outbreak.

Fortunately, the plague is only infectious while the sector is  actively  bat-
tling  the plague (Stage II).  The most effective method for curing plague has
been to isolate the sector by stopping all distribution, deliveries, movement,
etc.  originating from the sector once an outbreak has been spotted.

This  includes  loading and unloading of ships and land units (since they can,
of course, carry plague), allowing explorations out of the sector, moving com-
modities  out  of the sector, distribution or deliveries from the sector, etc.
Basically, any people or commodities that originate  from  a  sector  actively
battling  plague  will  cause the destination sector (or ship or land unit) to
become infected.

Once an outbreak has been spotted, the plague takes on an infectious state  at
the  next  update.   There is very little time to isolate the sector and limit
deaths caused by plague.

NAME
   Plane-types - Description of different kinds of planes

Level: Basic

The general plane types currently available in Empire are:

   fighter  A general offense/defense plane. Historical examples include
            the FE.2B, the Sopwith Snipe & Camel, the Nieuport V-XVII, the
            Spad, and the Fokker planes. From WWII are the Me-109, the
            FW-190, the English Spitfire & Hurricane, the Japanese Zero,
            the American P-39, P-40, P-38, and the Soviet Yak series.
            Later planes include the Me-262, the Gloster Meteor, P-80,
            Mig-15. Korean War vintage planes are the F-87 Sabre, F-100
            SuperSabre, and the Mig-17. Vietnam Era planes are the F-4 &
            Mig-21. Later, NATO & WP models include the F-16 & F-15 and the
            Mig-23, 25, and 29.

            The main points of similarity are: 1 or 2 high performance
            engines, a single pilot, and plenty of guns/missiles. Duties
            include patrol/interception, escort, and light bombing.

   escort   These are planes optimized for escorting, with superior range,
            sometimes at the expense of fighting capacity. Examples are
            the Me-110 & the P-51. Note that this type is relatively rare,
            as long range heavy bombing was rare.

   naval
   fighter  These planes all sacrifice range and/or fighting power in order
            to fit on a carrier and carry the gear necessary to operate
            from one. Examples are the series of Short biplanes built in
            Britain, the Sopwith Baby & Cuckoo, the Gloster Gladiator, the
            American Wildcat & Corsair, versions of the Japanese Zero, the
            F8 Corsair, the F-4, F-14, and F-18. Many of the planes were
            multi-role, due to the relatively small plane capacity of their
            carriers. They were almost always inferior in performance to
            land fighters. Many of them carry dual engines.

   light
   bomber   These planes are tactical bombers, suited for strafing, combat
            support, etc. These range from the first trench bombers, such as
            the Junkers J-I and the Sopwith Snark & Dolphin, the Ju-87
            Stuka, the American P-47, various ground-attack versions of the
            Yaks, the Japanese Val and Kate, the British Typhoon, and many
            others.  Modern versions are the A-3 SkyWarrior, the A-4
            Skyhawk, the A-6 Intruder, the Su-22 Frogfoot, the Su-27, and
            various British models. A modern and most effective example is
            the A-10

            The common factors are maneuverability, the ability to take
            damage and still fly, and the ability to hit targets precisely.
            (Either through low-speed bombing, dive-bombing, or rocket or
            guided bombs/missiles) Their performance against fighters of
            any sort is poor, with few exceptions (notably the P-47, which
            was designed as a fighter, and used as a ground-attack plane
            due to its toughness) Many are naval, or have naval versions,
            since the requirements of a naval plane do not affect them as
            greatly as fighters.

   heavy
   bomber   These planes are build for long range and great load-carrying
            ability, and the ability to defend themselves against fighters.
            (Although that never worked more than middling well) Examples
            are the Handley-Paige bombers of WWI (especially the O/400), the
            German Gothas and Giants, the B-17 Flying Fortress, the B-24
            Liberator, the B-29 SuperFortress, the Avro Lancaster, the Short
            Sterling, and the Vickers Wellington, as well as the more modern
            B-36, B-47, B-50, B-52, B-1, and the Soviet Ant-4, Tu-20 Bear,
            Tu-2? Backfire, and others.

            The common factors are the extreme range, the ability to carry
            several tons of bombs, the wide range of defensive armament, and
            four engines.

   medium
   bombers  These were basically an intermediate stage between the light &
            heavy bomber, and were used for both purposes. Examples are the
            He-111, the Do-17, the B-25 Mitchell, B-26 Marauder, the A-20
            Havoc, the Avro Manchester, Armstrong Whitworth Whitely, the
            Russian Il-4 & I-15, and the Japanese Betty & Sally.

            These planes were essentially compromises, and were phased out
            as time went on. They could not bomb as precisely as a light
            bomber, nor as heavily as a heavy bomber.

   transports

            Initially, these were basically similar to civilian airliners.
            They could carry supplies or troops. (In Norway, the Germans
            captured airports and flew in troops) Later, they were used for
            paratroop landings. Eventually paratrooping became too dangerous
            for these planes (with the introduction of SAMs) and they were
            replaced by helicopter assault, with the transports going back
            to carrying supplies and equipment.

   transport
   helicopters

            These were made to transport assault troops. They also carry
            supplies & wounded, but their main duty was to deliver troops
            with greater precision, rapidity, safety, and cohesion than was
            possible with paratrooping. (They were also to replace the
            landing craft, as the Marines looked at the odds of an invasion
            fleet standing up to nukes)

   attack
   helicopters

            These supplement the light bombers, and specialize in the very
            precise application of firepower, as well as evading
            interception, by use of terrain.

   recon
   planes &
   satellites

            These provide precise information about enemy troop dispositions
            and movements. The first recon planes had no protection. Then,
            it was attempted to make them un-interceptable. This was done by
            simply being faster than anything the enemy had, such as the
            stripped down British Hurricanes, US P-38's & P-51's, or German
            FW-190's or Blitz-Bombers. Later, emphasis shifter to also being
            able to fly higher, as with the U-2 & SR-71. These planes are
            largely superseded by satellites now (for good or ill).

   ssm's
   & icbm's

            The first ssm's were used as strategic harassing weapons, and
            were almost useless. (German V-1 & V-2) There were also combat
            rockets, such as the Russian Katayusha's and the German
            Nebelwerfers, but these were essentially similar to artillery.
            The first true SSM's were the Russian missiles in the 1950's,
            such as the Frog. They were intended to deliver nuclear or
            chemical warheads at medium ranges, and to be un-interceptable.
            Later missiles increase payload & range.

            However, since we've artificially restricted the blast effects
            of nuclear weapons, I am merging these in with tactical
            missiles. (no need for an icbm unless you've got big nukes)

   marine
   missiles
            These are modern smart-missiles. They are naval weapons, such
            as the Harpoon, Penguin, Exocet. They are accurate missiles which
            may be launched at ships.

   sam's
            The first sams were nuclear-tipped, and intended to break up
            large attacking bomber forces. Later, they were made smaller
            and more accurate, and were intended to hit single targets
            at any speed or altitude.

   abm's    These are to shoot down missiles, and are mostly fantasy.

   asw
   planes   These are either long-range bomber type aircraft, with some
            sort of equipment for locating & killing submarines, or also
            helicopters, able to fly from most naval vessels.

These plane types differ in their fundamental capabilities; some can fly bomb-
ing missions, other carry cargo, others exist  to  shoot  down  other  planes.
Missiles are special; they are planes which fly one-way missions and cannot be
shot down by opposing planes.

The technology level at which the plane was built is very important.  The same
model plane built at a higher tech level will outperform the planes built at a
lower tech level.

The particular planes available and their attributes are  given  by  the  show
command.  The fields given in the output are as follows.  For building:

  lcm  the amount of lcm to build the unit,
  hcm  the amount of hcm to build the unit,
 crew  the number of military this plane has as crew
avail  the amount of avail used to build this plane
 tech  minimum tech level to build this unit,
    $  cost of the unit in dollars,

For the stats report the fields are:

    acc  bomb accuracy, low is best; a 0 accuracy implies no ability.
   load  bomb load/cargo capacity.
    att  air-to-air  combat  attack rating (reduced by low eff, can't go below
         1/2 of base).
    def  air-to-air combat defense rating (reduced by low eff, can't go  below
         1/2 of base).
    ran  base range (in sectors).
   fuel  amount of fuel used each trip.
stealth  the percentage chance this plane has of evading detection

The abilities are given as a set of attributes for each plane.  These include:

 tactical  Pinpoint bombing ability.  Can be put on interdiction  and  support
           missions.  Tactical missiles may be launched at sectors unless they
           have "marine" ability in which case  they  may  only  be  fired  at
           ships.
   bomber  strategic bombing ability
intercept  Interception  and  escort  ability.   May  be  put on escort or air
           defense missions.
    cargo  cargo-carrying ability
     VTOL  vertical take-off ability -- no need to use airports
  missile  missile -- one shot, can be launched (see info  launch).   "marine"
           missiles  may  only  be  fired  at ships, "tactical" missiles which
           don't have "marine" capability may only be fired at sectors.
    light  light, can land on carriers or be carried on a submarine
      spy  spy ability, for recon missions (see info recon,  info  bomb,  info
           satellite)
    image  full  imaging  capability  - satellites with this ability show much
           more (see info satellite)
satellite  a satellite - stays in orbit until shot down
  stealth  a stealth plane - has a chance of not triggering intercepts
      SDI  Intercepts tactical missiles.

           cepts
  x-light  xtra-light, can be carried and used on any ship or land unit with a
           non-zero xl capacity. (see info Ship-types)
     helo  ship-helicopter, can be carried and used on any ship  with  a  non-
           zero hl capacity. (see info Ship-types)
      ASW  Has  ASW  (anti-submarine  warfare)  ability.  May use sonar & bomb
           subs.
     para  may be used to paratroop
   escort  Escort ability only.  May be put on escort missions.
     mine  Can lay mines (see info mine).
    sweep  Can sweep mines (see info sweep).
   marine  Missiles with this ability may only be launched at ships.

Each plane has a stealth rating. The stealth rating of a group  of  planes  is
that of the plane with the LOWEST rating.

NAME
   Products - Formulas for the production of commodities

Level: Basic

Many  Empire  sector types exist specifically to turn raw materials into prod-
ucts.  Some of those products may, in turn, be considered  raw  materials  for
other industries which produce other products.

This table gives the constituents and costs for each type of product.

NOTE:  All  costs given in the table are for 100% production efficiency.  Many
processes depend on technology level or educational level of  the  country;  a
note  like  p.e.=(tlev+10)/(tlev+20)  means  that  a country with a technology
level of 0 has a production efficiency of 50% and will only  produce  one-half
of  the specified product amount for the given costs, whereas a country with a
technology level of 100 will have a production efficiency of 92%.

In addition, some sectors don't produce raw materials as well as  others,  and
some produce much better than others.  Use the "show sector capabilities" com-
mand to see production efficiencies and other useful information on  producing
sectors.

The  rate  at  which  constituents are turned into products is governed by the
work accrued to a sector (see info Innards)  divided  by  the  units  of  con-
stituents  per  unit  of product.  E.g., it takes 3 units of work to produce 1
shell; 2 units to incorporate the light construction materials and 1 unit  for
the  heavy.   Natural  resources  such  as fertility count as one unit of con-
stituents; e.g., it takes 1 unit of work per unit of food produced.

    shells  Shell  production  efficiency   depends   on   technology   level;
            p.e.=(tlev-20)/(tlev-10) Shells cost $3 each to manufacture.  Each
            requires 2 units of light construction materials  and  1  unit  of
            heavy  construction materials.  You must have a minimum technology
            of 20 to produce shells.
      guns  Gun     production     depends      on      technology      level;
            p.e.=(tlev-20)/(tlev-10)  Guns cost $30 each to manufacture.  Each
            requires 5 units of light  construction  materials,  10  units  of
            heavy  construction materials, and 1 unit of oil.  You must have a
            minimum technology of 20 to produce guns.
      iron  Iron  ore  production  depends  on  mineral  content   in   mines.
            Extracting iron ore is free, and the mineral content of the sector
            is not depleted by mining iron.
      dust  Gold dust production depends  on  gold  mineral  content  in  gold
            mines.  Extracting gold dust is free, but the gold mineral content
            of the sector is depleted by mining gold dust.  In addition, moun-
            tains  may sometimes produce gold dust as well.  The efficiency of
            mountains producing gold dust may not be as good  as  gold  mines.
            Use  the  "show sector capabilities" command to see the production
            efficiency of sectors.
      bars  Gold bars are produced in banks.  Gold bar production  depends  on
            gold  dust  in  gold  mines.   Gold  bars  cost $10 to produce and
            require 5 units of gold dust each.
      food  Food production efficiency depends on  technology  level  and  the
            fertility  of  the sector; p.e.=(tlev+10)/(tlev+20).  Growing food
            is free, and the fertility of the sector is not depleted by  grow-
            ing food.
       oil  Oil  production efficiency depends on technology level and the oil
            content of the sector; p.e.=(tlev+10)/(tlev+20).  Pumping  oil  is
            free,  but the oil content of the sector is depleted by extracting
            and refining oil.
 petroleum  Petroleum    production    depends    on     technology     level;
            p.e.=(tlev-20)/(tlev-10).   A  unit of petroleum costs $1 to manu-
            facture.  Every 10 units of petroleum require 1  unit  of  oil  to
            produce.   You  must  have  a  minimum technology of 20 to produce
            petroleum.
       lcm  Light construction material production efficiency depends on tech-
            nology  level;  p.e.=(tlev+10)/(tlev+20).  Producing lcms does not
            cost money, but requires 1 unit of iron ore.
       hcm  Heavy construction material production efficiency depends on tech-
            nology  level;  p.e.=(tlev+10)/(tlev+20).  Producing hcms does not
            cost money, but requires 2 unit of iron ore.
       rad  Radioactive material production efficiency depends  on  technology
            level, which must be at least 40.  p.e.=(tlev-40)/(tlev-30).  Pro-
            ducing rads cost $2 per ton, and depletes the uranium  content  of
            the sector.
 education  A  unit  of education (a class of graduates), costs $10 to produce
            and requires 1 unit of light  construction  materials  (see  "info
            Education").
 happiness  A  unit  of  happiness (happy strollers), costs $10 to produce and
            requires 1 unit of light construction materials (see "info  Happi-
            ness").
technology  Technology  production  efficiency  depends  on  education  level;
            p.e.=(elev-5)/(elev+5).  A unit  of  technology  (a  technological
            breakthrough),  costs  $5  times  the number of ETUs per update to
            produce, and requires 10 units of light construction materials,  5
            units  of oil and 1 unit of gold dust.  For more details about how
            technology level is calculated from technology  units,  see  "info
            Technology".
  research  Research   production   efficiency  depends  on  education  level;
            p.e.=(elev-5)/(elev+5).  A unit of research (a medical discovery),
            costs  $90  to produce and requires 10 units of light construction
            materials, 5 units of oil and 1  unit  of  gold  dust  (see  "info
            Research").

NAME
   Research - How Research level is calculated each update

Level: Expert

If  the  RES_POP  option is in use, the research level of a country determines
the maximum number of civilians, mil, and uw's that can live in a sector.  The
maximum then is:

   400 + 600 * ((research*4 + 50)/(research*3 + 200))

So,  for  example, at 0 research, after an update, the max you could have in a
sector would be 550 civs, 550 uws, and 550 mil.  Note that in the case of cap-
tured  sectors,  the  research level of the current owner governs, even if the
old owner of the sector had a higher/lower research.

If, after population growth, there are more civs than the  limit,  the  excess
are lost. Uw's & mil work the same way, each being individually limited.

The  research  level also affects the likelihood of plague outbreaks.  (Unless
the NO_PLAGUE option is used, of course)

The nation command will display, among other  things,  your  current  research
level.

The procedure determining how much your research level goes up every update is
exactly the same for research as it is for technology (see "info  Technology")
except  for  the  fact  that  "research  log  base"  is  always 2.00 and "easy
research" is always 0.75.  But besides  this,  research  bleeds,  decays,  and
leaks in exactly the same way as technology.

NAME
   Sector-ownership - Sector ownership

Level: Basic

In  order to own a sector, you must have at least one of the following present
in the sector:

   1) mil
   2) a land unit
   3) non-captured civilians

If at any time you do not have at least one of those 3 things in a sector, you
will  lose  control  of it.  If you are not the old owner at the time you lose
the sector, it will revert to the old owner.  Otherwise it will revert to  the
deity,  country  #0,  even  if another country's land units are present in the
sector.  If there are no people at all in the sector, it will  revert  to  the
deity.

Note  that this means that if you attack a sector and do not move in, you will
not gain possession of it. If there are civilians in the  sector,  the  sector
will  revert back to the original owner. If there are no civilians in the sec-
tor (and no mil or units, because you  just  killed  them),  the  sector  will
revert back to the deity.

Similarly, if you abandon a sector, it'll revert immediately.

                                    BASICS

SEA  -  Sea  sectors  form natural barriers that can only be crossed by ships,
(made in harbors, below), or spanned by bridges, (also below).   You  can  not
designate  anything  else  to  be sea nor can sea be designated to be anything
else.

MOUNTAIN - Mountain sectors form another natural barrier that cannot be redes-
ignated;  however,  they  can  be  moved through (at great expense in terms of
mobility units).  In an emergency, they can be used as capital. See info capi-
tal  for  more information.  In addition, mountains can only hold a maximum of
1/10th the civilians and uncompensated workers that other sectors can normally
have.   And  military,  civilians and uncompensated workers that will actually
produce anything there are also limited to 1/10th.

SANCTUARY - Sanctuary sectors are created when a new nation is created.   They
are inviolate in that no one can fire at them or attack them.  This protection
ends when the new country first moves out of the  sanctuary  (called  breaking
sanctuary);  the  sector then becomes a capital.  NOTE: in games with multiple
sanctuaries per country ALL sanctuaries become capitals when any one does!

WASTELAND - This is the result of the explosion of a nuclear  device.   Waste-
lands are uninhabitable forever.

WILDERNESS  -  Most  of  the world is wilderness at the beginning of the game.
Wilderness has no particular attributes; you can move into it  if  unoccupied,
thereby  making  it  your territory, but will probably want to designate it as
something else once you own it.

PLAINS - Plains sectors form another natural barrier that cannot  be  redesig-
nated.   They  can be occupied and moved through however.  In addition, plains
can only hold a maximum of 1/20th the civilians and uncompensated workers that
other  sectors  can  normally have.  And military, civilians and uncompensated
workers that will actually produce anything there are also limited to  1/20th.

CAPITAL  -  Capitals  are  the source of bureaucracy time units (BTU's).  They
accrue in proportion to the efficiency of the capital and the number of civil-
ians at work in it.  (see info BTU).  Most commands use up BTU's, (see list of
commands for numbers of BTU's used per command).  A nation may only  have  one
active  capital  at  a  time (although many sectors may be designated as capi-
tals).  The capture of a capital will result in the loss  of  money  from  the
victim nation (see info capital), Capitals are twice as efficient at defending
against attack as other sectors (except fortresses).  Use the capital  command
to  make a capital the active one.  In a pinch, mountains can be used as capi-
tals. They generate very few BTU's, and represent being 'holed up in the moun-
tains',  perhaps  like  Pancho  Villa.   Note  that  if the BIG_CITY option is
enabled, then 'c' sectors stand for 'cities' and can hold 10x  as  many  civs.
They  also get a 10x packing bonus for moving civs, and require a certain num-
ber of lcm's, hcm's, and $$ to build (see show sect build).

PARK - Parks are provided solely for the convenience  of  the  people.   Parks
require  construction  materials  to provide maintenance services and add to a
nation's happiness level.  The conversion of raw materials takes  place  auto-
matically at a rate dependent on the efficiency of the sector, the presence of
the required materials, and the number of workers in the sector.

                                COMMUNICATIONS

HIGHWAY - Whenever you move civilians, ore, gold, etc, mobility units (mob  on
the  census) are consumed dependent on how far and how much you move.  However
if the movement is through 100% efficient highway it costs much less to  move.

RADAR  - Radar stations can scan the surrounding area (up to 16 units away for
100% efficiency) and generate a radar plot identifying sector  types  at  dis-
tances up to 1/3 their range and ships up to their full range.

BRIDGE  HEAD  -  Bridge  heads are the land based ends of bridges.  They, like
harbors, turn construction materials into bridge spans; see info build for the
details of this process.  and are much like highways except for three things:
(1)  Bridge  spans provide food through fishing, (the fertility can be thought
of as fish-count).  (This is deity-settable, however.. in many games,  bridges
do not provide food. Be sure to ask)
(2)  Bridge spans must maintain at least 20% efficiency or else they collapse.
(3) If the only bridge head supporting a particular bridge  span  is  redesig-
nated  as  something else the bridge span will collapse.  (If the EASY_BRIDGES
option is in use, bridges do not need bridgeheads.  Check info build  for  the
details)

BRIDGE  TOWER  -  Bridge towers are like bridge heads you can build out in the
ocean.  You can only build bridge towers from a bridge span, and in open water
(not  adjacent  to any land or other bridge towers.)  From a bridge tower, you
can build other bridge spans.  The BRIDGETOWERS option must be enabled for you
to be able to build bridge towers.
Bridge  towers  must  maintain  at least 20% efficiency or else they collapse.
Any bridges connected to the tower will collapse as well, unless  held  up  by
another  adjacent structure (bridge head, bridge tower or land if EASY_BRIDGES
is enabled.)

                                  FINANCIAL

BANK - Banks are used for smelting and storing  gold  bars.   They  include  a
smelter  to refine gold dust into gold bars.  While the bars are stored in the
bank the busy little bankers invest them and return a  profit  on  their  use.
Banks  are of the Fort Knox variety; they are more impervious to shelling than
any other sector and militia in them fight twice as  hard  against  attack  as
those  in  industries.   Banks are also particularly adept at moving gold bars
around; bars are moved and stored in groups of four thus fewer mobility  units
are required to move a gold bar from a bank than anywhere else.

                                  INDUSTRIES

DEFENSE  - In defense plants construction materials are turned into guns.  The
conversion of raw materials into guns takes  place  automatically  at  a  rate
dependent  on the efficiency of the sector, the presence of the required mate-
rials, the technology level of the country, and the number of workers  in  the
sector.   See  info Products for information on the materials required to pro-
duce guns.

SHELL INDUSTRY - These sectors are similar to  defense  plant  sectors  except
they turn construction materials into shells.  The conversion of raw materials
takes place automatically at a rate dependent on the efficiency of the sector,
the  presence  of the required materials, the technology level of the country,
and the number of workers in the sector.  See info Products for information on
the  materials  required.   One  shell is used each time you fire, (except for
submarines which use three shells to make one torpedo).

MINE - Mines produce iron ore by digging it out of the ground.   The  rate  at
which  it  is  produced  is  dependent on three factors; the efficiency of the
mine, the number of civilians working in the mine, and the mineral sample  for
the  sector  (min  on  the census report).  Iron is a renewable resource; i.e.
digging up iron does not deplete the mineral content of the sector.

GOLD MINE - Gold mines are similar to ordinary  mines,  (above),  except  that
they  produce  gold  dust.   The rate at which it is extracted is dependent on
three factors; the efficiency of the sector, the size of the  labor  force  in
the  sector,  and  the gold sample for the sector (gmin on the census report).
The raw gold dust can be transported to any sector but if it is left in a bank
sector  it  will be refined into bars automatically .  Gold is a non-renewable
resource; i.e. extracting the gold depletes the gold content of the sector.

URANIUM MINE - Uranium mines are very similar to gold mines,  (above),  except
that they produce radioactive materials.  The rate at which it is extracted is
dependent on three factors; the efficiency of the  sector,  the  size  of  the
labor  force in the sector, and the uranium content of the sector (uran on the
census report).  Uranium is  a  non-renewable  resource;  i.e.  extracting  it
depletes the content of the sector.

HARBOR  - Harbors combine shipyard facilities and docks.  Construction materi-
als are converted into ships and the ships can be loaded and unloaded  in  the
harbor,  (see info load).  No ships are constructed until the build command is
given, (see info build).

WAREHOUSE - Warehouses are used to store shells, guns, iron, gold dust,  food,
oil,  light  construction materials, and heavy construction materials.  Moving
the above out of a warehouse only takes one tenth the mobility  cost  it  nor-
mally would.  Note: warehouses are often used as distribution centers.

AIRFIELD  - Airplanes can only be built in airports and most can only take off
and land at airports.  (though some can take off and land in other sectors and
some can take of and land on aircraft carriers see Ship-types for details)

AGRIBUSINESS  -  These sectors are large farms and provide food.  Agribusiness
sectors produce as much as five times as much food as other sectors.  The har-
vesting takes place automatically at a rate dependent on the efficiency of the
sector, the fertility of the sector (fert in the census), the technology level
of  the  country,  and the number of workers in the sector.  See info Products
for details.

OIL - Oil fields produce oil by sucking it out of the ground.  The  extraction
of  oil takes place automatically at a rate dependent on the efficiency of the
sector, the oil content of the sector (oil on the census report), the technol-
ogy  level  of the country, and the number of workers in the sector.  Oil is a
non-renewable resource; i.e. extracting oil depletes the oil  content  of  the
sector.

REFINERY  -  Refineries  produce petroleum by processing oil.  This production
takes place automatically at a rate dependent on the efficiency of the sector,
the number of workers in the sector, and  the technology level of the country.

LIGHT - Light manufacturing plants produce light construction  materials  from
iron.   This  production  takes place automatically at a rate dependent on the
efficiency of the sector, the iron in the sector, the technology level of  the
country, and the number of workers in the sector.

HEAVY  -  Heavy manufacturing plants produce heavy construction materials from
iron.  This production takes place automatically at a rate  dependent  on  the
efficiency  of the sector, the iron in the sector, the technology level of the
country, and the number of workers in the sector.

                            MILITARY / SCIENTIFIC

FORTRESS - Fortress sectors have many special characteristics;  you  can  fire
guns  from fortresses, whenever an attack is launched from a fort or on a fort
the militia in the fort are stronger than military in any other type of sector
by  an  amount  proportional  to  the efficiency of the fort. (See information
below in sector stats) Also, forts and commodities  in  forts  are  MUCH  more
resistant to damage than normal sectors.

TECHNOLOGY - Technical centers are bastions of pure technology research, which
is to say universities with massive defense department grants.  They turn con-
struction materials into technological advances thereby raising the technology
level of the country (which affects gun ranges, pollution, etc.).  The conver-
sion  of  raw  materials  takes place automatically at a rate dependent on the
efficiency of the sector, the presence of the required materials,  the  educa-
tion level of the country, and the number of workers in the sector.

RESEARCH - The research lab is a bastion of pure medical research, which is to
say it is  a  large  university  with  massive  March-of-Dimes  funding.   The
research lab turns construction materials into medical discoveries which raise
the research level of the country and help retard the spread of disease, (usu-
ally  caused  by the pollution from technical centers).  The conversion of raw
materials takes place automatically at a rate dependent on the  efficiency  of
the sector, the presence of the required materials, the education level of the
country, and the number of workers in the sector.

NUCLEAR - The nuclear lab is a bastion of applied technology, which is to  say
it is an immense underground building filled with evil geniuses playing Adven-
ture on huge computers.  The nuclear lab  turns  construction  materials  into
nuclear weapons.  No devices are constructed until the build command is given,
(see info build).

LIBRARY/SCHOOL - The library/school sector is the foundation  of  a  country's
educational structure.  They use up construction materials to produce units of
education which raise the educational level of the country (which affects  the
efficiency of research and technology sectors).  The conversion of raw materi-
als takes place automatically at a rate dependent on  the  efficiency  of  the
sector,  the  presence of the required materials, and the number of workers in
the sector.

ENLISTMENT - The enlistment sector is the boot camp of  Empire.   It  converts
civilians  into  militia,  once  the  efficiency level has been raised to 60%.
Unlike the other production sectors, it uses only militia as a workforce,  and
converts civilians in the sector into military.

HEADQUARTERS  -  This  is where basic militia are converted into units.  Head-
quarters also give a bonus to reaction radius for units in them, allowing them
to defend better.

The  show  command  can be used to show special things about sector types. For
example:
   [##:##] Command: show sect build

   sector type    cost to des    cost for 1% eff   lcms for 1%    hcms for 1%
   f              500            5                 0              1

   Infrastructure building - adding 1 point of efficiency costs:
          type          lcms    hcms    mobility    $$$$
   road network            1       1           1       1
   rail network            2       2           1       3
   defense factor          1       1           1       1

Cost to des is the cost to designate the sector type. This is charged when you
give the designate command.  Note that if the BIG_CITY option is enabled, then
'c' sectors also cost money, lcm's and hcm's to build, and they can  hold  10x
as many civs as other sectors.

You can also build infrastructure into your sectors.  That is how the mobilty,
for both commodities and units, is determined.  You can also raise the  defen-
sive  value  of  your sectors to a maximum amount (which is shown in the "show
sect stats" described below.)

   [##:##] Command: des 2,0 f
That just cost you $500 Cost for 1% efficiency is the $$  cost  per  point  of
efficiency built.  Lcms/Hcms for 1% are similar.

   d defense plant             2   1.00  1.50     1   1   1   1     1

This  shows the relative cost to move through the sector types, and the offen-
sive and defensive values of the sector types. For example, a capital  with  a
100%  defensive efficiency is twice as good as a park (since the base value is
1.00.)  All sectors start with a 0% defensive efficiency, thus they all  start
with a defense of 1.00.  You can increase the defensive capability of any sec-
tor up to the amount shown by the "max def" column.

   [##:##] Command: show sect capabilities

   There is no information on sector capabilities.

NAME
   Ship-types - Description of different types of ships.

Level: Basic

Some of the ships currently available in Empire are:

torpedo-boat   These ships have been misrepresented in Empire. They were
          designed to kill large ships by swarming them and launching
          torpedoes. In fact, they were projected to be so effective
          that the French 'Jeune Ecole' (Young School) of naval officers
          advocated abandoning battleships entirely, saying that they
          would be helpless in the face of the torpedo-boat. In reality,
          the torpedo boat was limited by it's short range, deficient
          sea-keeping ability, and the battleship's quick acquisition of
          numerous light quick-firing guns and machine guns. They were
          effective when used in large numbers, but tended to die a lot.

destroyer These include three kinds of ships. First is the 1880-1910
          destroyers, originally 'torpedo-boat destroyers', and meant to
          be cheap ships to screen the battleships. Second is the
          1910-1950 version, meant to kill submarines with sonar and
          depth-charges. Lastly is the 1950-1965 destroyer, an all around
          ship, with ASW and ASuW (anti-surface armament). After that,
          they type mostly died out, as it had gotten too large.

frigate        Originally, these were ships of about 200-400t, with a crew
          of 200-500, armed with from 30-50 large cannon plus numerous
          small cannon. They were intended to scout for ships of the
          line, and protect/destroy commerce. After about 1860, the type
          died out entirely, and was replaced by light cruisers. In the
          1960's, the type was resurrected for a new class of ASW (anti
          submarine warfare) ships of small-medium size.

light cruiser  The class came into existence in the 1860-1905 period to provide
          fast ships suitable for extended deployment in far-away places.
          They were intended to out-class local defense boats, and not
          much else. Much was sacrificed to give them long-term speed
          end endurance. They were not intended to have a role in a major
          battle.

heavy cruiser  This class has a dual role. It was intended to reinforce the
          light cruisers in the colonies, providing a heavier punch and
          more armor, and also to be scouting elements in major fleet
          battles.

ship-of-the-line
pre-dreadnought
dreadnought
battleship     While the names change, the purpose remained the same: a ship
          that brings heavy guns close to the enemy and destroys him. It
          also was much used for off-shore bombardment, and for ships
          of the line, minor invasions. (A complement of 300-400 marines
          and 600 sailors allowed a ship of the line to land up to 750
          fighting men at any desired point. Small squadrons of these
          ships could (and did) take over towns, attack fortresses by
          surprise, and generally make life miserable for the defense).

          The pre-dreadnought was a battleship with a limited number
          (usually 4) of heavy guns, numerous lighter guns ('secondary'
          and 'tertiary' armament), and heavy armor on vital portions
          of the ship. They were hard to kill, even for themselves, as
          they had only a few guns that could penetrate the armor of
          their peers.

          The dreadnought was introduced in an article in Jane's Fighting
          Ships by an Italian designer, who received permission to publish
          his design after the Italian government decided that it was
          too large and expensive for them. The design/concept was seized
          upon by First Sea Lord Jacky Fisher, who rushed completion of
          the first ship, the Dreadnought, through in only 1 year. (An
          amazing feat and a major record) The Dreadnought gave its
          name to the entire type of ship, having 8-12 large calibre
          guns, few secondary & tertiary weapons, and good armor. (As
          can be guessed, the threat posed by torpedo boats had diminished
          considerably, mostly with the quiet abandonment of the policy
          of close blockade, and the advent of the destroyer)

          The battleship of the 1918-1945 period was faster, and carried
          a new AA capacity, especially in the latter years of the period.

          After 1945, the class died out (except for 4 ships)

          For our purposes, a battleship 1 is a ship of the line, a
          battleship 2 is a pre-dreadnought, a battleship 3 is a
          dreadnought, and a battleship 4 is what was called a battleship
          or (sometimes) super-dreadnought.

battlecruiser  These special ships existed in the 1905-1920 period, prior to
          the widespread introduction of oil fuel. They had full battle-
          ship guns, and a large speed advantage over the battleships,
          but very little armor. They were initially the pet project of
          First Sea Lord Jacky Fisher, who intended them to both kill
          the heavy/armored cruisers of the time, and to scout for the
          battleships. With their heavy armament (and name), their
          function inevitably blurred, and they were used in combat
          against full-fledged battleships, where they died like flies.
          With this (and with the introduction of oil fuel, which made
          battleships their equal in speed), they were phased out.

ASW cruiser    These ships came into being in the 1965-present period in
          response to a need for a large ASW ship to carry ASW helicopters
          and command equipment. It typically carries full ASW armament,
          as well as a minor ASuW capability.

missile boat
missile frigate
missile cruiser     These ships range in size from 100t missile boats (the modern
          replacement for the torpedo-boat) to the 6000-8000t missile
          cruiser. They all are designed to bring missiles to bear on
          the enemy. (The first successful missile boats were Egyptian,
          and used against the Israelis in the 1967 Arab-Israeli war)

          The missile frigate and cruiser also serve as SAM ships.

landing craft  These ships are relatively unique, being used mainly in the
          1942-1950 period. Before that, landings were carried out by
          frigates, ships-of-the-line, light & heavy cruisers, &
          pre-dreadnoughts, all of which could land a large number of
          men. With the introduction of the concept of beach-defense by
          the Germans, these ships were invented to get large numbers of
          men on the beaches quickly. After 1950, their functions were
          largely assumed by the helicopter.

aircraft carrier
light carrier
escort carrier These ships are designed for various purposes. At first,
          carriers concentrated on scouting for the battleships. Later,
          it was proved that airplanes could sink battleships (Thanks to
          Billy Mitchell here), and the emphasis moved to all-around sea
          control. Still later, with the disappearance of the battleship,
          a large power-projection capacity was added.

          Light carriers were simply smaller versions of the large or
          'fleet' carriers, and were used for the same duties.

          Escort carriers were usually hastily converted merchantmen,
          and carried small numbers of fighters and ASW planes. (Some
          merchantment, in fact, were equipped with 1 fighter and a
          temporary catapult. When threatened by enemy planes, the
          fighter took off. When it was done, it ditched, and the pilot
          was (theoretically) picked up by the merchant ship's convoy.
          This was used several times, and worked!)

submarine The submarine was originally intended, in the 1900-1910 period,
          to fill the same role as the torpedo boat, using stealth to
          get to the battleships instead of speed. It was a strictly
          defensive weapon, without much speed or endurance.

          In the 1910-1925 period, the sub was much enlarged, and use in
          a combination anti-battleship (sank at least 20)/anti-commerce
          role. Endurance was much improved, and the sub could now
          operate a long distance from its home port.

          In the 1925-1945 period, the sub steadily grew large and more
          capable, gaining mostly in speed, sonar ability, and endurance.

          After 1945, nuclear power vastly increased the subs endurance,
          making it effectively infinite. Sonar was also vastly improved,
          and removed the reliance upon the periscope. The subs armament
          was also vastly improved with the addition of the SLM & SLBM.

minesweeper    Usually converted fishing vessels, small, and expendable. They
          found and destroyed mines with a variety of tricks, including
          cables & magnetism.

oiler          These ships represent the whole range of refueling ships.

These  units  types  differ  in  their fundamental capabilities; some can fire
guns, some cannot; each has it's own specific abilities & roles.  The capabil-
ities  of  each  ship are given by the show command.  The headings are as fol-
lows. For the building data:

   [##:##] Command: show ship build

  lcm  The lcm required to build the ship.
  hcm  The hcm required to build the ship.
avail  The avail (work) required to build the ship.
 tech  The minimum technology required to build the ship.
    $  The cost of the ship.

The headings for the stats listing are

   [##:##] Command: show ship stats

def  defensive armament of the ship
spd  the distance/mu for moving (in relative units)
vis  how visible the ship is, (relative units)
spy  how far the ship can see, (i.e. how good the communication equipment is),
     again in relative units
rng  twice  the  distance  the  guns  can fire, The range formula is (rng/2) *
     ((tech + 50) / (tech + 200))
fir  the number of guns the ship can fire at once
hel  The number of helicopters the ship can carry. (If the SHIPCHOPPER  option
     is enabled)
xpl  The  number  of  extra-light  planes  the  ship can carry. (If the XLIGHT
     option is enabled)
pln  The number of light planes the ship can carry.
lnd  The number of 'light' land units the ship can carry. If  the  ship  is  a
     supply ship, it can carry even non-'light' units.
fuel  The ship's fuel capacity & usage. (see info fuel) (If the FUEL option is
     enabled)

Each ship can carry a certain amount of products and has certain capabilities.
These  are listed under the cargoes & abilities section.  The cargoes give the
number of each product that can be carried.  The abilities are as follows.

   [##:##] Command: show ship capabilities

NAME
   Spies - How spies work

Level: Expert

There  is  a  land  unit type "spy".  These can be very valuable land units to
have wandering around the planet...

Spies are very special land units.  They are able to  march  into  any  sector
(owned or unowned) and look about.  Of course, if you are marching in unallied
territory, there is a chance you will get caught.

If a spy is caught by a friendly or neutral country, the country  will  get  a
message  that  a  spy was spotted in their country.  If the spy is caught by a
hostile or at war nation, the spy gets shot on the spot.  The chance  of  get-
ting caught while marching about is inverse to the efficiency of the spy.  So,
at 100%, a spy has a 10% chance of getting caught.  at 10%, a spy has  a  100%
chance of getting caught.  Thus, you want efficient spies.

Spies  are  also  very  fragile.   If  they  are caught in any kind of combat,
shelling, bombing, etc. and take ANY damage at all, they die.

Spies may also be snuck on shore via ships using the  "assault"  command.   If
you  assault a sector using just spies, they have a 10% chance of making it on
shore without being spotted (no matter what their  efficiency).   If  spotted,
the  same  rules apply for how a spy is dealt with.  If you mix spies and mil,
the spies must fight just like normal units.  And, since any damage they  take
kills them, this is very risky usage of spies.

You may locate spies using the "llookout" or the "spy" command.

Use your imagination on how to eradicate errant spies. ;-)

Submarines may carry up to two spy units.

When unloaded from a ship, spies are not given over to the owner of the sector
as other units are.

NAME
   Syntax - The Empire command syntax

Level: Basic

The Empire Shell (command interpreter) expects input in the form:
   [##:##] Command: VERB ARG1 ARG2 ...
VERB  is  any  one  of the Empire commands on the Q*command list (what you see
when you type list-- e.g.  map, move, info, etc).

The number of ARGs varies from command to command.  In  most  cases  the  ARGs
need  not  be  supplied on the command line; any that are not supplied will be
obtained by prompting.  The exception to this rule are  those  ARGs  that  are
enclosed in [square brackets] in the command list.  The presence of these ARGs
changes the way the command is carried out.

Certain basic argument types recur often and are abbreviated in the  following
ways.

  ::=  'se',  'sh',  'l',  or  'p' for sector, ship, land unit, or plane
   respectively.  If "sector" is not a possibility, then 's' will likely  suf-
   fice for "ship".

 ::= either a country number or a country name

  ::= any one, (or unambiguous abbreviation), of the list of commodities
   found in info Selector:
 ::= loan number
 ::= sector coordinates in the form: x,y
 ::= sector(s) in the form:

         lox:hix,loy:hiy ?cond&cond&...

   lox, hix, loy, hiy are coordinates bounding the rectangular area to be con-
   sidered

   cond is a condition of the form:

         

     is  either a , as above, a number in the range 0 to 65536, a
   sector designation, (m for mine, c  for  capital,  etc),  a  type  of  unit
   (frigate, cavalry, etc), or a selector found in info Selector.
    can be any one of:
   <  less than
   =  equal
   >  greater than
   #  not equal

   Thus mob=100, ore#0, 7=guns, civ#mil, des=b are examples of legitimate con-
   ditions, (note lack of embedded spaces), and
      [##:##] Command: census -3:3,-3:3 ?des=+&gun=5&mil>civ
   will list all highways within 3 of your capital with  exactly  5  guns  and
   more military than civilians.

   Similarly,
      [##:##] Command: deliver f -9:9,-9:9 ?f_del=0
   will  allow  you  to  set  up  food  delivery in all the sectors that don't
   already have food delivery.

   Note that  hix,  hiy,  and  ?cond  are  all  optional.   Also,  the  entire
   lox:hix,loy:hiy section may be replaced by either #, #0, #1, #2, or #3, ...
   which refer to realms which you can define.  (See info realm.)  Note that #
   and  #0 are equivalent.  Also * refers to all sectors, and @x,y:dist refers
   to all sectors within dist of x,y.
 ::= one ship number
 ::= fleet designation, which may be  a  list  of  ships  separated  by
   slashes  (`/'),  a  fleet letter, the character tilde (`~') which means all
   ships not in a specific fleet, or a rectangular sector area.
 ::= either a single ship number or a fleet designation.

   Note that  specifications may have an optional ?cond&cond...   argu-
   ment like that used for  arguments.  For instance:
      [##:##] Command: ship ~ ?des=d&mil>5
   will  list all destroyers that have more than 5 military which are not cur-
   rently in any fleet.

   The output from commands may also be sent to a file or another  process  by
   utilizing these alternate syntaxes:

      [##:##] Command: VERB ARG1 ... > FILE
   which sends the output to the file FILE.

      [##:##] Command: VERB ARG1 ... >> FILE
   which appends the output to the file FILE.

      [##:##] Command: VERB ARG1 ... >! FILE
   which  sends  the  output  to  the  file  FILE, replacing the file it if it
   already exists.

      [##:##] Command: VERB ARG ... | PROGRAM [ARGS...]
   which send the output of the command to the program PROGRAM  with  optional
   arguments  ARGS.   This  is  most useful when PROGRAM is some type of pager
   like more(1) or less(1).

   The Empire shell also recognizes a few control characters:

        _n_a_m_e  _m_e_a_n_i_n_g
   interrupt  Abort command and return to Empire command level
        quit  Exit Empire
         EOT  Exit Empire

NAME
   Taxes - How taxes are calculated

Level: Expert

Civilians  exist in Empire to work and provide cash to the government.  Simply
by existing, they generate revenue to their host country in proportion to  the
efficiency of the sector in which they work.

The  military-industrial complex exists in order to siphon off hard-earned tax
dollars.  Military cost (in general) about ten times as  much  as  a  civilian
pays in taxes.

In  addition,  final  goods  and  services cost money to produce.  Ships, land
units, planes, guns and shells are all examples of the costs inflicted upon  a
helpless  government  by the military-industrial complex.  Also, services such
as technology research, medical research, and even happiness (money and  lcm's
can  buy happiness here...)  cost something to create.  Consumer items such as
food, lcm, hcm, and all other intermediate goods (or raw materials) cost noth-
ing other than the hard work of the oppressed citizenry.

Note  that it takes ten civilians to keep one soldier in the field.  Note also
that the only way to make money is either to be pacifistic and let your nation
accumulate  wealth  by having a small standing army, or by selling products to
other nations. Also, land units can multiply the strength of each mil,  making
them  perhaps  more  economical,  if  you  already have made the technological
investment.

Also note that captured civilians only pay 1/4 the normal taxes.  They like to
hide  money until they are all finally agree to become naturalized citizens of
their new government.

NAME
   Technology - How technology level is calculated each update

Level: Expert

Your  technology  level  affects  the range that guns can fire, the range over
which radar is effective, the range that planes can fly  and  the  range  that
torpedoes can travel, among other things.

The  nation  command will display your current technology level and technology
factor.

This is how your new technology level is determined every update:

(1) Technological breakthroughs are produced in tech centres.
See "info Products" or the "production" command to find out how many
technological breakthroughs you are going to produce.  Your update
telegram will tell you the number of technological breakthroughs
produced in your various tech centres in a line like this:
  technological breakthroughs (7.2) produced in 3,1

(2) Calculate tech delta from technological breakthroughs
In the output of the "version" command, you will see a line like this:
  Tech Buildup is limited to logarithmic growth (base 2.00) after 3.00.

In this example, the "tech log base" is 2.00 and the "easy tech" is
3.00.  To find out what your tech delta for an update will be, subtract
"easy tech" from the number of technological breakthroughs you are
producing and then add 1, then take the logorithm with base "tech log
base" and then add the "easy tech" back on.

For example, say you had a number of tech centres producing a total of
18.0 tech units.  Then to calculate your delta, first subtract "easy
tech" from it and then add 1 to obtain 16.0, then take the log base 2.0
of that which is 4.0 (since 2 to the power 4 is equal to 16), and then
add the "easy tech" back on to get a tech delta of 7.0.

(3) Tech bleed
If the ALL_BLEED option is enabled, then you will gain extra technology from
all countries producing tech, and there will be a line in the
"version" output like this:
  The technology/research boost you get from the world is 50.00%.

If the ALL_BLEED option is turned off, then you will gain extra
technology from the countries with whom you share a two-way alliance,
and the line in the "version" output will look like this:
  The technology/research boost you get from your allies is 50.00%.

In both cases, the amount of tech you get is 50% of the average amount
of tech delta for all eligible "bleeders".  Note that a fundamental
difference between these two cases is that in the ALL_BLEED case, only
countries which are producing tech are counted in the average, whereas
in the case where ALL_BLEED is turned off, the amount of tech bleed is
averaged among all of your allies whether they are producing tech or not.

Your net tech delta will be printed in your update telegram as:
  3.000 technology (2.0000 + 1.0000)
where the 3.0000 is your net tech level gain, and that is broken down into
how much you produced (2.0000) and how much you got from tech bleed (1.0000).

(4) Tech decay
After your net tech increase has been added to your country's
technology level, then your technology level will decay.  The amount of tech
decay is printed in the version output as:
  Nation levels (tech etc.) decline 1% every 96 time units.
The number of time units in an update is printed in the version output as:
  An update consists of 60 empire time units.
Every update, your tech is reduced by
  decay = (tech level) * (decay rate) * (etu per update) / (decay etus).
So if your tech level was 200.0, and the decay rate was as above, then
you would lose:
  decay = 200 * 0.01 * 60 / 96 = 1.25
and so your tech would go down to 198.75 from decay.

(5) Tech leak
If your tech level is much lower than the tech level of the highest
tech country in the world, then every update, there is a chance that
one of their high tech secrets will get leaked into your country.

Take the tech level of the highest tech country in the world and
divide by 5.  Call this the "minimum tech".  If your tech level is
lower than the "minimum tech", then every update, there is a 20%
chance that your tech level will increase by one third of the
difference between your tech level and the minimum tech.

Note that if the TECH_POP option is enabled, technology costs  proportionately
more $$$ to make as your civilian population grows past 50,000 civilians.

NAME
   Time - Definitions of BTU and ETL

Level: Expert

Because  of the unique nature of Empire governments, (i.e. the decision makers
spend most of their time on vacation.  Hmmm, not so unique actually), and  the
fact  that  ideally the Empire environment will mirror the real world, various
heuristics dealing with time have been implemented.

The first is the Bureaucratic Time Unit (BTU) concept which keeps track of the
potential for doing work possessed by your government.

The  second heuristic, (i.e. hack), is the Elapsed Time Limit (ETL) which lim-
its the amount of time that players may be logged on each day.  The ETL is not
cumulative  and is reset to some particular value, (often two hours, check the
version command to be sure), every night at midnight.

The ETL and BTU counts are displayed with each command prompt as follows:
   [##:##] Command:
The first ## is the Elapsed Time today, in minutes.  This number starts  at  0
every midnight.  The second ## is the number of BTU's remaining.

NAME
   Trade-ships - How to use trade ships

Level: Basic

Trade  ships  are  special  ships,  with a different function than most Empire
ships. They are in the game only if the TRADESHIPS option is enabled.

Trade ships simulate internal or external trade. In the real world,  countries
make  goods that they can make cheaply, ship them somewhere they're expensive,
and sell them, making a profit.

In the empire version, you make a trade ship, using lots of cm's, and  costing
$2500. You then sail it to a harbor somewhere and scuttle it. You then receive
money, with a varying rate of return.

The trade ship MUST be scuttled in a harbor that is at least 2%  efficient  to
make  money.  (In  other  sectors,  it sinks quietly, like most ships) You may
scuttle it in either a harbor you own, or the harbor of an ally.  Pirates  who
capture  a  trade  ship  may also gain money from it, just as if they were the
lawful owner (although the news knows the difference)

The return rate is based on the straight-line map  distance  from  the  harbor
where the trade ship was built to the harbor where it is scuttled.

You have to sail it at least 8 sectors to get any money at all. At less than 8
sectors, you get nothing, not even your $1750 back. Nothing, nada, zilch, zip,
nothing.  Once  you make a trade-ship, you're pretty much committed to sailing
it at least 8 sectors...

Currently, the return rates are:

             Distance sailed          Return rate
             0-7            NO MONEY
             8-13           2.5% * distance
             14-24               3.5% * distance
             25+            5.0% * distance

For example, if you sail the ship 10 sectors from  the  harbor  where  it  was
built  and  scuttle  it in a harbor there, you would get 125% of the money you
paid for it, or $2188. If you sailed it 15 sectors to a  harbor  and  scuttled
it, you would get 153%, or $2678.

Use  the payoff command to see how much the trade ship would pay were it scut-
tled in a harbour at its present location.

If you scuttle a trade ship in the harbor you do not own, you get a 20%  bonus
(applied after the value is multiplied by the return rate above), AND the per-
son owning the harbor gets 10% of the cash you make as  a  bonus  (the  amount
before  the +20% bonus is applied) You still get the full amount, but he makes
money as well.  (Peaceful trade enriches BOTH countries more than trading only
internally).   For  the  devious, no, being allied with yourself does not mean
you get +20% when scuttling in your own harbors.

For example, using the #'s from above, if you sailed 15 sectors, and  scuttled
in  an  allied  harbor, you'd get $2188 * 1.2 = $2.6K, and your ally would get
$2188/10 = $218.

CASH GAINED IS ALSO MULTIPLIED BY THE EFFICIENCY OF THE TRADE  SHIP.   So,  if
you get shot down to 21%, don't expect to get the full amount...

If  you capture a trade ship, you are free to scuttle it in any harbor you can
get it into, receiving full cash calculated normally.

The cash return is multiplied by the efficiency of the ship, so less efficient
ships produce less money.

Captured  trade ships may be scuttled as if they were yours (although you will
get some bad publicity in the news) Payoff is still based on the distance from
the harbor where the trade ship was built, not the sector in which it was cap-
tured.

You can also use the "order" command to set up automated trading  routes  with
trade  ships  and have them navigate and automatically scuttle themselves when
they reach their destination.  See "info order" for more information on  this,
but basically you can do things like this:

       Step 1) Make a harbor
       Step 2) Get cms distributed/delivered to your harbor each update.
       Step 3) Find a destination harbor to sail to
       Step 4) build tradeships in the harbor each update
       Step 5) load civs and food on the trade ships each update.
       Step 6) order the trade ships to sail and autoscuttle in the dest harbor.

You  can then just repeat steps 4, 5, and 6 each update, and never worry about
your trade ships again.  Unless someone starts intercepting them, that is...

NAME
   Unit-types - Description of the different types of land units

Level: Basic

Some of the units currently available in Empire are:

infantry  The Bloody Infantry. Lotsa guys on foot with guns. They're
          slow, and they carry their supplies in horse-drawn wagons,
          which slows them down even more. Slow. They're also not
          terribly good at scouting. They don't attack very well,
          with a multiplier ranging from 1 to 1.5 or so with better
          tech. However, they really shine on defense, with a multiplier
          from 1.5 to 3.0. If you want to hold a line... use infantry.
          They're fairly resistant to shelling and bombing, with the
          later types of infantry units being better.

cavalry        Empire starts just at the end of the age of cavalry. They're
          quick, and they scout pretty well. They're better at attacking
          than defending. They are pretty easy to kill with shelling or
          bombing. Still, if you want a low-tech unit to go somewhere
          quick, they're the guys.

supply         Supply units range from horse and wagon to truck units. Early
          supply units are slow, but the later supply unit types are
          motorized and are faster. Supply units carry a bunch of stuff,
          but try your best not to get them in combat, because they don't
          enjoy it, and they're REALLY bad at it. Supply units can give
          supplies to land units, as well as forts/ships/sectors. See
          info supply.

lt armor  Armor units may be light, medium, or heavy. Light armor units
armor          have much the same uses as cavalry, although they are a good
hvy armor bit less fragile. Medium armor is medium-fast, good for general
          attacking, while heavy armor is slow, but good for assaults,
          any situation where you need to destroy a heavily-defended
          fixed point.

          All armor is better at attacking than defending. Higher tech
          types of armor units are better at defending, however. Armor
          gets much of its combat advantage from its mobility, being
          able to attack and move in, severing supply lines & blocking
          reaction & reinforcements.

          Armor is fairly resistant to shelling/bombing.

artillery Artillery is a long range killer. You can use it to shell
lt artillery   sectors, but it can often be more effective when used as
hvy artillery  support for your attacks. Lt artillery has more mobility,
mech artillery but less damage. Hvy artillery has less mobility, but more
          damage. Mechanized artillery gives you good damage and good
          mobility, but is very expensive.

          The better the accuracy of the artillery, the better it is
          at assisting your troops or shelling ships. The better the
          damage rating, the better the damage done. High-damage, low
          accuracy artillery is mostly good for shelling sectors, while
          high-accuracy artillery is good at supporting your troops,
          or shooting at ships.

          All artillery is bad at attacking, but can usually defend in
          a not-horrible fashion. Artillery units are, however, pretty
          vulnerable to shelling and bombing. (except for mech artillery)

engineers Engineers are the most versatile unit. They can lay mines,
mech engineers clear mines, defend well, attack well, work on sectors, etc.
          The drawbacks? Well, they're VERY expensive and not very
          big. Mech engineers have vehicles and are much faster and
          more resistant to damage.

mech infantry  These two types of infantry are faster. Mech infantry is
motor infantry also more resistant to damage and even better on defense.

marines        These units are like improved infantry, but more expensive and
          harder to make. Their best use is for assaulting beaches, but
          they do make superior infantry if you have to use them that
          way.

security  These units are good at fighting guerrillas, but not for
          much else. They fight about as well as low-tech infantry,
          and their smallish size makes them not worth much.

          They do help you when shooting helpless civs (see info shoot),
          and fight guerrillas during the update. The security troops
          get a chance to 'raid' the guerrillas and kill some of them
          before the guerrillas fight. This will reduce your casualties
          from guerrilla war.

radar units    These units are high-tech. They give you the ability to
          map the enemy easily as you advance. Try not to get them
          into combat, as they're horrible at it, and they're very costly.
          They're generally motorized, so they're pretty fast, and they
          all get shelled/bombed hard.

aa unit        These units are good defensively, and fight planes well. They
          are a mechanized unit, and move & survive pretty well. Only
          units with the FLAK ability can fire AA.

Use the "show" command to see units stats and capabilities.

These  units  types  differ  in  their fundamental capabilities; some can fire
guns, some cannot; each has it's own specific abilities & roles.  The capabil-
ities  of  each  unit are given by the show command.  The headings are as fol-
lows. For the building data:

   [##:##] Command: show land build

   lcm  The lcm required to build the land unit.
   hcm  The hcm required to build the land unit.
  guns  The guns required to build the land unit.
 avail  The avail (work) required to build the land unit.
  tech  The minimum technology required to build the land unit.
     $  The cost of the land unit.

The headings for the stats listing are

   [##:##] Command: show land stats

att  the attack multiplier of the land unit
def  the defensive multiplier of the land unit
vul  the vulnerability of the unit to bombing/shelling (1-100)
spd  the distance/mu for moving (in relative units)
vis  how visible the land unit is, (relative units)
spy  how far the land unit can see, (i.e. how good the  reconnaissance  equip-
     ment is), again in relative units
rad  the unit's reaction radius
rng  twice  the  distance  the  guns  can fire, The range formula is (rng/2) *
     ((tech + 50) / (tech + 200))
acc  the firing accuracy of the unit
fir  the number of guns that fire when the unit fires
amm  ammo: the number of shells the unit uses when fighting or firing
aaf  the aa fire rating of the unit
fc/fu  The land unit's fuel capacity & usage.  (see info fuel)  (If  the  FUEL
     option is enabled)
xpl  The number of extra-light planes the land unit can carry.  (If the XLIGHT
     option is enabled)

Each land unit can carry a certain amount of products and has certain capabil-
ities.  These  are  listed under the cargoes & abilities section.  The cargoes
give the number of each product that can be carried.   The  abilities  are  as
follows.

   [##:##] Command: show land capabilities

  xlight  the unit can carry xlight planes. (If the XLIGHT option is used)
engineer  the unit can lay/sweep mines, work on sectors/fortifications/etc.
  supply  the unit can supply other units
security  the unit is good at fighting guerrillas and shooting helpless civil-
          ians
   light  the unit can be carried on ships (note that  any  unit,  even  units
          that  are not 'light', can be carried by a non-submarine supply ship
          that is otherwise able to carry units)
  marine  the unit is good at assaulting
   recon  the unit is good at gathering intelligence. It will do better  using
          llookout, and will report enemy units in batter better.
   radar  the unit has radar capability
 assault  the unit may be used in assaults

NAME
   Update-sequence - The order of events at the update

Level: Expert

This document gives a rough order of events during the update.

1) First, prepare all sectors in the world, row by row, going from top
     to bottom, left to right

     a) fallout is checked, if FALLOUT is defined
     b) guerrilla warfare is checked
     c) if the sector doesn't have the plague, see if it catches it
          otherwise plague the people
     d) if there are no civs or mil in the sector, it reverts to the deity
     e) taxes are collected from civs & uws. Mil are paid.
     f) if the sector is a bank it makes $$ proportional to its efficiency

2) Then, in order of country #, deal with each country:
     a) pay for military reserves.
     b) in order of set priorities, 1-39, 1 going first, then 2, etc.
          1) produce for owned sectors of that type
                  a) if the sector is a cap, it costs $$ equal to
                  the # of etus: np->nat_money -= etus;
               b) people in non-sanctuary sectors eat
                    1) If not enough is available, the sector

NAME
   Basics - The basic rules for playing Empire

Level: Basic

First, there are no real rules to playing empire.  What you do is what you do.
There are some general guidelines here, and some deities may be more forgiving
than others.

One  player,  one country.  You man NEVER use any country other than your own.
It is ok for two people to play one country but it is NEVER ok for one  person
to  play  two countries.  If you are caught doing this, your countries will be
removed from the game.  In addition, your registrations for future  games  may
be declined.  DON'T DO IT.

Ok, but what do I do when I'm away?

     1)  you may turn over your country to someone who has never played anyone
     else's country in that game.  You MUST tell the deity if you do  this  as
     he/she/it will be watching who is playing what.
     2) you may turn your country over to the deity.

Bugs:  if  you find a bug, you are REQUIRED to report it to the deity.  I will
not let other people know about the bug and in most cases, you may exploit  it
until  it  is  fixed.  Punishment for use without telling: at least $50,000 or
getting your country removed from the game.

Denial-of-service attacks are forbidden.  Any form of attack that  prevents  a
player from connecting to the server is against the rules.  This includes let-
ter bombing.

NAME
   Clients - Clients which communicate well with the Empire4 Server

Level: Basic

   What follows is a list of clients which support the new Empire4
   protocol.  All of these clients may be found on the Wolfpack Empire
   Archives located at:
     http://www.empire.cx
   or
     ftp://ftp.empire.cx/pub/empire/

   empclient-2.8   - full support

   If you are using one of these clients, then you should type
   "toggle inform" once you have broken sanctuary.  These clients
   are fully asynchronous, which means that they are able to respond
   immediately when an unexpected message arrives from the server.  So,
   for example, if someone sends you a "flash" message, then the message
   will be printed on your screen immediately.  Similarly, with "inform"
   toggled on, you will be informed the moment a telegram arrives.  Note,
   the server remembers your toggle flags when you log out, so you do not
   have to type "toggle inform" again the next time you connect.

   other clients   - no support

   Most other clients should work fine with the Empire4 server, however
   they may get confused if a flash message comes in.  Users of other
   clients should keep the "inform" flag toggled off, and ask a friend to
   send them a "flash" message to see how the client handles it (note,
   you must declare friendly relations towards them in order to receive
   the flash message).  If the flash message confuses your client, then I
   recommend you type "toggle flash" to turn flash mode off.

In  addition, there are a list of commands which have been added to the server
to help the development of clients.  They are:

      dump - Dump sector information
      ldump - Dump land unit information
      sdump - Dump ship information
      pdump - Dump plane inforamation
      ndump - Dump nuclear stockpile information
      lost - Report lost items

See the various info pages on these for complete  documentation  on  how  they
work and how you can use them to help improve your clients.

In addition, there is a "timestamp" field on each object (sectors, ships, land
units, planes, nuclear stockpiles, lost items) that you  can  use  to  compare
against to keep data between clients and the database in sync with each other.
These timestamps are kept in systems seconds, so they should be accurate  down
to 1 second.  Every time an object is changed, it's timestamp is updated.

                       Defense Against Nuclear Attacks
                      Through the Denial of Information
                                by Tom Tedrick

A  very  good defense against nukes is to make it as difficult as possible for
other players to find out where your country is, and thus to make maps of  it.

Here are some simple steps that you can follow:

 1)  Shoot  down  all  planes  that  fly over your airspace.  It helps to have
     numerous airfields, say one airfield for every 25 sectors or  so.   Every
     airfield  should  be  within  interception distance of several other air-
     fields, so that it is more difficult for an enemy to destroy  or  capture
     it.   If  an  airfield  is  detected  and  nuked,  you  still have backup
     airfields.  Every important sector should be within interception distance
     of several airfields.

 2)  Seal off all entrances to your inland seas by building bridges and laying
     mines (so no enemy ships can penetrate the area for mapping purposes).

 3)  Sink all surface vessels and submarines near your coastline.  Have  large
     fleets of destroyers posted around exposed coastal areas covering all sea
     sectors where enemy subs might try to  sneak  in  for  mapping  purposes.
     Usually  two fleets of 30 destroyers each are enough.  Navigate the whole
     fleet one sector, stop and look for subs, navigate one more sector,  stop
     and  look  for  subs, and so on, until the fleet has made a circle and is
     back in its starting position.  Sink any subs you find, of course.

     There is a maximum number of around 30 ships that can be in  a  fleet  if
     you want to maneuver the whole fleet by fleet name (see info fleetadd).

 4)  Establish  alliances  under the condition that secrecy is maintained with
     respect to map information.  Thus other allied countries can serve  as  a
     buffer zone against enemy countries.  Many players are willing to be good
     allies.

 5)  Destroy or capture nearby radar stations.

 6)  Destroy or capture enemy air bases within range of your  country.   Until
     enemy  technology  gets  high  enough to launch against any target world-
     wide, they will often try to get someone to let them have an airbase hid-
     den near your country and launch nuclear strikes from there.  I've always
     been able to find these if I worked at it.

 7)  Use psychological warfare.  Nukers get tired of nuking you if it seems to
     have no effect.  For example, have numerous false capitals, so that when,
     after great efforts, they manage to find what they think is your capital,
     and  nuke it, only to discover that it was a fake, they will get discour-
     aged.  These fake capitals are also very useful as backups in  case  your
     real capital is discovered and destroyed.

     When  an  enemy  gets close to doing real harm, a counterattack can often
     divert attention away from the current attack.  Psychologically,  attack-
     ers  seem  to  underestimate  the harm they are doing to you if you don't
     give out any information about how you are being affected, and they  seem
     to overestimate the danger to themselves from your counterattack.

                         Ship Networks and the Art of
                            Transferring Supplies
                                by Tom Tedrick

Build  large quantities of ships.  When they're 100% efficient, load them with
military and food (and civilians) if possible.  Load guns and  shells  if  you
have  them, but since they tend to be scarce, only a few ships will have them.
Navigate them one by one as far as they will go.  Leave only one ship in  each
sector (this makes it difficult for an enemy to sink very many of them, due to
mobility restrictions and the problem of locating and identifying them one  by
one).  On your maps, mark the ship number in the appropriate sector.  Each sea
sector thus has at most one ship number.

Unless there is something in particular you want to do with a particular ship,
leave it sitting in its sector indefinitely.

As you build more and more ships, move them out one by one.  If you leave ship
X in a sector that already contains ship Y, ship Y should have  full  mobility
by  then.  Navigate ship Y as far as it will go, then leave it sitting until a
new ship comes along.

Every ship in the network is now likely to be within range of some other ships
in  the network.  If a ship requires any supplies, you can load them on a ship
in a harbor, navigate it out, transfer the cargo via tend, navigate the tended
ship,  transfer its cargo, and so on, until you reach the any ship in the net-
work.  If you need military for assaulting or boarding, guns  and  shells  for
firing, torpedoing or laying mines, or if you simply want to move stuff into a
distant harbor, you can do it using several tend and navigate operations.

This has been particularly useful for sinking subs.  I don't have enough  guns
and  shells to keep all of my 100 or more destroyers fully armed, but when one
of the unarmed destroyers spots a sub, I can  arrange  to  transfer  guns  and
shells to it from a loaded ship (or from a harbor).

It's a very simple system from the player's standpoint, because all the player
has to do is build the ship, navigate it, mark its number on the map, and for-
get  about it until a use for it arises.  As more ships are built, the network
automatically expands without requiring any planning.  You don't have to  keep
anything  in memory, except the ship number on your map.  If any enemy surface
ship gets trapped in the network, it's quite likely you can capture  it,  even
if all you have is cargo ships (battleships, landing craft, and carriers could
take some work though).  If an enemy sub is spotted by  your  destroyers,  you
can almost always sink it.  If a convenient target for an assault appears, you
can get the necessary military there.

                       Some Tricks to Use When Fighting
                              by Various People
                               (Mostly by Tom)

The trick for boarding destroyers: you need a bunch of cargo  ships,  both  to
make  several boarding attempts and to tend military.  When you try to board a
ship, both the attacker and defender lose the same amount of mobility.   First
you  have  to get the destroyer's mobility to be negative.  Then you just keep
trying to board it from one ship after another until you win.  That's where my
ship network method comes in handy.  I usually have swarms of ships I can sur-
round enemy ships with.

If I have planes, my normal method is to take a sector I can see,  put  enough
military to hold it, designate it e if it has lots of food, or maybe something
else if there is a reason.  Then get information about  the  adjacent  sectors
and  take  the  most  promising  one.  Without planes it's more of a struggle.
Anyway, I kind of zig-zag into the country taking the  most  interesting  sec-
tors,  ignoring  the  others.   This really seems to freak people out, when an
enemy takes a path right through the heartland.

I would use planes (so having numerous airports each with  a  fair  supply  of
fighters, spread around your country, would be the best countermeasure), ships
(having forts loaded with guns and shells covering all coastlines helps a lot;
also  having destroyers and subs spread around your coastal waters in order to
spot and counterattack enemy ships, also have bombers to bomb enemy ships, and
radar stations to spot them is useful).

I  would  invade by land, firing from forts, (mainly you need to counterattack
actively when the enemy takes any sectors in your area, also forts  with  guns
and shells help a lot).  I would capture islands and build bridges to get into
your country (so watch all offshore islands with bridge span range).

Have a lot of shells in warehouses ready to be moved to  the  front  (you  can
move four for no mobility cost).

Bombing  enemy  ships  spotted by radar seems to work pretty well for the most
part.  If he has an aircraft carrier you can torpedo it.

You never know exactly what may happen, sometimes you get lucky when you think
it's  hopeless.   Even if a plan has only a small chance of working, sometimes
it's worth a try, especially if the enemy has to actively do something to stop
it.

You should always have at least two capitals sectors, in case you lose one.

Just  a tip on empire tactics: mobility is the key to dealing with many empire
problems. Its often the bottleneck which interferes with various  things,  and
the decisive advantage that gives victory to the attacker.

It has been over a year now since I first sat down and thought in a serious
way about writing this guide.  It has been a long trip with many interesting
turns and developments.  When I first started, the version of Empire that
this guide has ultimately been written for had not yet been released.  Now,
with this project nearing release I find that yet another new version of
Empire is coming out.  I look on in near despair as I realize that this guide
may very well soon be outdated.  Nevertheless, I feel compelled to release
this information in what might be considered a final form.

However, I hope that this is not the final form.  With new versions of
Empire coming out in the very near future I hope that some other potential
author steps forward and takes up the banner of educating the new player.
I caution you though that such a work as this takes quite an effort.

To the reader and any critics or even cynics that might be reading, I say
that I am not writer.  I never was, and I never intend to be.  There are
certainly enough writers in the world to write almost everything the world
could want to know about in print.  I was never skilled in the art of proper
style for any sort of writing.  Please, be kind and keep this in mind.

I wrote this guide because I felt there was a great need for something of
this nature.  I have watched so many players come to the network looking
for information on Empire, such as the rules, or information on how to play.
One can get information about the various commands available to oneself
within the game, but to understand how to use those commands effectively
and get skilled at running a country is a far greater task.  Many new
players have despaired after playing their first game for lack of the
requisite knowledge to play effectively.  Some come back fighting hard
in the next game, but many just disappear never to be heard from again.
This guide was written with the hope that if the new player is supplied
with the basics, they can advance in skill more quickly than previously
possible and not despair at their first defeat.

I am hoping that within the near future two other companion guides to
this one will be written and released to the net.  These two guides will
be intended to make the average player a better player or even expert,
and to teach fledgling deities how to compile and establish a, solicit
entries for , and effectively run, a game.  Some people have commented
to me that the time spent on these guides would be better spent if I
were to spend time programming for Empire instead.  It is my belief that
in teaching players to be better players, and teaching deities how to be
a deity should that guide be released, the potential pool for
programmers of Empire will increase.

I can not take credit for the idea of this guide.  The need for such
a guide I think was painfully obvious to a great many players.  Some in
fact did engage in projects to fill that need.  Every such attempt has
fallen short, in my humble opinion.  Witness the large number of people

User's Guide to Empire                                  4

who still ask the network, "How do I play?" and even more importantly
the lack of sufficient answer to such people's questions.  In my highest
hopes, I dream that someday soon that answer will be "Get a copy of the
User's Guide to Empire, which is available via FTP from xx.xx.xx".

This work was made possible by the contributions of several Empire players.
This work would not have been completed without the insights and assistance
of many Empire players and deities.  To the Empire community as a whole,
I say thank you for your priceless contributions.

Chapter 1 :-: What is Empire?

     Empire is a game in which you are pitted against several other
     players in a country vs. country format.  There are economies to
     run, armies to support, policies to generate, and allies and
     enemies to make.  The game supports various features that make
     certain aspects of the game seem to parallel the "realistic"
     world.  These include satellites, planes, banks, parks, etc.

     Empire, in the version herein described, is a very complex
     game.  The closest game that most people will know that is
     analogous to it is the game known as Risk.  However, Empire is
     more complex by a factor of at least one hundred.  Nevertheless,
     as a result of the computer aiding you every step of the way, the
     game is not difficult to play, though it can be difficult to
     learn.  If you read this guide thoroughly, and use it as a
     continuing resource, you can help make learning this game a lot
     easier.

     It should be noted that in learning to play this game, you
     may become frustrated or feel daunted by its complexity.
     Several players have noted that they almost gave up on Empire,
     until one day when everything seemed to start to make sense.
     I call it the "threshold level of understanding" after which
     learning the art of Empire becomes several grades easier, and
     players learn substantially faster.  I urge you to stay with
     it until you get to that level.  It may take some time, but it
     is well worth the effort.  This guide is intended to get you
     to that threshold level of understanding.

     Games usually take two to three months depending on various factors
     that are changeable by the person who runs the game prior to its
     inception.  Some games, known as blitz games, last a day or three
     and will wear out your finger tips from typing too much, will cause
     your family and loved ones to be tremendously upset with you for
     missing breakfast, lunch and dinner for three days straight, will cause
     your stomach to argue constantly with you about its right to
     food, and are a tremendous amount of fun.  Blitz games are not
     for the light of heart nor are they meant for the beginner.

     For more information concerning the basic scope of Empire,
     refer to the game itself.  Within the game, there are
     various help entries accessible through the command 'info'.
     This guide is intended to go well beyond the scope of help
     available from 'info'.

     Empire, the game, has evolved through many different forms
     over the last decade.  There are still numerous versions
     for various computers around.  The version herein discussed
     is BSD Empire, written for the most part by Dave Pare along
     with a lot of help from net people.  As release time approaches
     I am aware that Mr. Pare is working on BSD Empire V2.0.
     This guide is only current to version V1.1.5 of BSD.  I wish

User's Guide to Empire                                  7

     the future author of the guide to V2.0, whomever that might be,
     the best of luck and bequeath that person a family size bottle
     of aspirin for personal use.

Summary: Empire is a very complex game that has a rather steep learning
      curve.  Most of the complexity of the game can be handled by
      the commands available to you, the game server itself, or tools
      that you use to better your country.  Tools are described later
      in this text.

Chapter 2 :-: How to get into a game of Empire.

     The most common way of finding about about games that are about to
     happen is by monitoring the newsgroup rec.games.empire on your local
     news reading program. Other ways are via e-mail by getting to know
     several players with whom you correspond over the network.  Some
     games are by invitation only but these are few and far between as
     usually a game is better with more people in it.  If you do not know
     how to use your local news reading program, ask a local site consultant
     or find a brochure about the news programs available.  One of the most
     common newsreaders can be reached by typing 'rn' from your unix
     prompt.  If you have VMS for an operating system this may not be true.
     To go directly to the rec.games.empire newsgroup you could type in
     'rn rec.games.empire'.

     Before entering a game of Empire, consider the amount of time that
     you have available to play the game.  Two hours a day for a four
     update per day game is usually the norm.  If you are inexperienced,
     and have not fought in wars before, that two hours will dramatically
     increase should war break out between you and another country.

     Note that it is easy to get addicted to the game.  The player should
     be aware of this prior to playing.  Play in moderation.  This is
     obviously not meant to scare you off.  It is merely a word of caution
     to some people.  Remember to play in moderation.

     If you do decide to join in an upcoming game of Empire, then you will
     have the pleasure of playing one of the best games around.  Empire has
     been described as being the most complicated game ever created.
     Despite the fact that the game was created for computers and has
     been in existence for several years, as yet no robot player has been
     developed nor is it anticipated.  It is possible to build such a
     robot, but it would be a huge task.  Do not be dismayed though.
     Most of the complexity of Empire is handled by the server and client.
     There is a fair amount of what is called "micro-managing" that may
     need to be done to be a highly successful nation. However, it is
     not a necessary thing to do.  Furthermore, there are many tools
     (described later) that can handle the micromanaging aspects to
     a great degree.

     After you find out about a game, and decide that you do want to
     play in that upcoming game, you need to contact the "Deity".  The
     "Deity" is the person who runs the game.  You should mail him/her
     with information about yourself and your country.  A customary
     basic form for registering your country to play might contain
     the following information:

     Country name: (any name you like, from Brianville to USofA)
     Rep: (this is your *password*)
     Net address: (the address at which you can be contacted over the net)
     Skill level: (1-10..10 being the best, 1 being beginner)

     It might be necessary depending on the Deity to include all addresses

User's Guide to Empire                                  9

     from which you might be playing.  With the proliferation of suns as
     general user machines this is becoming more and more a chore, and
     few deities require it.  It might suffice to say "mickey@*.buffalo.edu"
     which might cover all machines you play from if you played from
     SUNY-Buffalo.  Mickey, of course, is just an arbitrary username chosen
     for this example.

     Empire players connect to games in progress through a program known
     as a "client".  This program handles communication between your
     computer and the computer that the game is running on.

     There are several versions of clients available.  Some are more
     "capable" than others in that they can make decisions easier for
     you or make the decisions themselves.  They are intended to reduce
     the amount of work you have to do to maintain your country though
     in some cases they actually increase the amount of work you have
     to do.  I have listed places from which you can get other types
     of clients from in the FTP listings in appendix C.

     Sources for basic client program is available by FTPing to
     ucbvax.berkeley.edu.  For the user's benefit, I have included
     a copy of a session in which a user FTPs to ucbvax, retrieves the
     source, compiles the source and establishes the appropriate
     environment variables to connect to a game.

     Note that the following example will work ONLY on a unix,
     ultrix, or other flavor of unix operating system.  This will
     not work for the VMS client.

You can change hosts on-the-fly by using environment variables -- see

------------------------------------------------------------------

     Since you are playing across a network of computers, it is possible
     that there will be problems along the way in connecting to the server
     from the computer you play on.  What follows are some common connection
     errors.

Problem 1:
autarch{client}!>empire
connect: Connection refused

Problem     This generally means that you have either set your environment
       variables wrong (see 'setenv' from earlier in this chapter), or
       the server at the host site is not currently running.
Solution  (1) Check your environment variables by issuing a 'setenv' command.

User's Guide to Empire                                  13

       (2) Wait for the server to come up.

Problem 2:
autarch{client}!>empire
connect: Connection timed out

Problem   This generally means that there is a network outage somewhere
       along the network.
Solution  (1) You can monitor the network by using two unix commands located in
       /usr/etc on most unix systems.  These are 'ping' and 'traceroute'.
       /usr/etc/ping 128.205.7.3 for instance will send a ping at the
       host with ip address 128.205.7.3.  If that machine can be reached
       from your machine across the network it will return:
       128.205.7.3 is alive
       traceroute 128.205.7.3 will request responses from each site along
       the way.  This is useful for seeing which site along the way is
       causing the outage.
       (2) This solution is easier, but more frustrating.  Wait.

Problem 3:
autarch{client}!>empire
Country name? 
Your name? 

        -=O=-
3 country in use by mickey@lictor.acsu.buffalo.edu (pid=5797)

Problem     This one is potentially nasty.  It means that another process is
       logged into your country.  This could be from multiple sources.
       1: Your friend who is playing your country as well.
       2: A process of yours that got accidentally hung.
       3: The network hung your remote process even though your local
          process is now terminated.
Solution  (1) Go kick your friend in the head :-)
       (2) Kill your process 'nicely'.  To find the process execute a
       'ps -x' command and find the appropriate process number:
       autarch{client}ps -x
         PID TT STAT   TIME COMMAND
       3555 t1 S      0:00 -usr/new/csh (csh)
       3575 t1 R      0:00 ps -x
       3559 ?  S      0:00 -usr/new/csh (csh)
       3560 ?  S      0:00 (empire)
       The offending process number in this list is 3560.  To kill it,
       simply type the command 'kill 3560'.  After that, all should be
       well.  Try entering the game again.
       (3) If your process is hung on the server machine, you can
       do one of two things.  First, you can mail the Deity with the
       "pid", or process identification number.  This number is listed

       Your process is now unhung, and your country should be ready to play
       once again.

Problem 4:
autarch{myclient}empire
Country name? 
Your name? 

Bad password

Problem   The server does not accept the password you typed as being correct.
Solution  Try typing it again.  Try using capital letters at the beginning of
       the password as well, or the entire password in caps.  If this does
       not work, mail the Deity and inform him or her of the problem
       and what the password should be.

Problem 5:
autarch{myclient}empire
Alarm clock

Problem   Your connection to the server is not responding.
Solution  The delay time for waiting for a response that is built into
       the client is not exceedingly long.  The theory behind this being
       that if it is taking you that long to get a response from the
       Empire server then it is not worth playing, since response times

User's Guide to Empire                                  15

       for information from the game are going to be pretty unbearable.
       Keep trying is probably the best solution.

     These are most of the problems that you will encounter in connecting to
     the game server.  There are some more problems that you might
     encounter, but generally they are not common.  If you can not reach
     your game server for more than a day, contact your deity and let
     him/her know that you can not connect.

Summary: Getting into a game of Empire is not terribly difficult. Setting up
      a client program should be a fairly painless task.  If it is not,
      do not be dismayed.  Get help from a consultant or another player
      if you can.  Some problems with the network may temporarily prevent
      you from playing.  Be patient, the network is a horse that should
      be shot, but generally it comes around after a while.

Chapter 3 :-: The primitive basics.

     There are a few basic commands and ideas that will help you get
     acquainted with Empire.  These are here summarized.

Concept: Sanctuary.
     All players begin a game of Empire in what is known as a sanctuary.
While you are in a sanctuary state you can not be attacked, overrun, or
otherwise hurt.  However, while you are in sanctuary you can not do
very many things.  In order to really begin playing the game you need
to do what is known as "break sanctuary".  You can do this using the
everyone starts with) will become capital sectors.  You are no longer
protected from attacks from enemy countries.

Concept: Movement in Empire.
     Paths of movement are indicated by several keys.  Path indicators
exist in a hex shape around the letter H on your keyboard.  Thus, y means
travel North-West, u for North-East, j for East, n for South-East, b for
South-West, and g for West.  Also, h means "stop" which terminates movement
of whatever you are moving.  There is one other key, v which "views" the
sector you are currently moving through.  Thus if I gave a movement path
of gggvgh the game would move whatever I am moving three sectors West, view
the sector at three sectors west of my starting point, then move one more
sector west and then stop.

Concept: Update
     Empire games have "turns" known as updates.  When an update occurs,
your country goes through economic growth or decline, interests are paid
on gold bars, military costs are paid for, mobility increases in your
sectors, etc.  You can do a great many things between updates, an update
merely does book keeping more or less, at a predetermined time.  To find
out when the next update is going to happen, you can type 'update' as
a command.

Command: map -10:10,-7:7
     This command will give you a map of the area immediately surrounding
your beginning two sectors.  Specifically, it will give you a map from ten
sectors West of your 0,0 to ten sectors East and from seven sectors North to
seven sectors South of your 0,0.

Command: explore civ 0,0 1
     This command allows you to move one civilian from your 0,0 and
"explore" into wilderness and mountain sectors.

Command: info commands
     This command will list the various commands available in Empire.
It is a very good idea to go through the information on each command
by typing 'info '.  This will help you get more acquainted
with the game.  Though this guide shows many commands and how to use them,
it is no substitute for the game's help itself.

User's Guide to Empire                                  17

Command: designate 1,1 +
     This command will enable you to designate a sector you own into
whatever you desire.  Usually, in the beginning of the game you will designate
sectors that you will not be using actively for a while into highways.
The above shown example of the command will designate your 1,1 sector into
a highway.

Command: telegram 
     Countries in Empire communicate with each other via telegrams.
These are private letters sent just like a telegram would be.  They have
a size limit, but there is usually more than enough room to say what you
want to say.  There is no limit to the number of telegrams you may send.

Command: announce
     Countries broadcast to the world via the command 'announce'.  These
announcements are similar to telegrams except instead of one country reading
the telegram the entire world can read it.

Command: read
     This command allows you to read any incoming telegrams or
announcements.  Empire will notify you when you have new incoming traffic.

Command: news {x number of days}
     This command will allow you to peruse the Empire newspaper.  It does
not make for great reading.  However, it is useful for intelligence gathering.
If you just enter 'news' as a command, it will print all the news since you
last read the news.  Entering 'news 3' will give you the news for the last
three days.  In big games, the news file gets quite large.

Summary: These are the basic ideas and commands of Empire.  Empire has a great
      many commands however, and the player should endeavor to learn them.
      Empire can be played with only a few commands but the additional
      commands are there for your best interests.  If you do not understand
      a command shown here, simply type 'info ' while in the
      game itself.

Chapter 4 :-: Geography in Empire.

     Maps in Empire are based on a simple hex design.  For example:

---------------------------------- There are three basic sector types in
                       Empire (note: "type" is different than
     /    /    /    /    /    "designation".  Designation refers to what
    /    /    /    /    /     that sector has on it, a factory or school
-4 |  .  |  ^  |  -  |  ^  |  .  | for example.  Type refers to what it is
       /    /    /    /    /  built on).  There are:
      /    /    /    /    /   seas : .
-3    |  -  |  -  |  .  |  .  |    mountains : ^
     /    /    /    /    /    wilderness  : -
    /    /    /    /    /     When using the Empire map, you use an "X,Y"
-2 |  .  |  -  |  -  |  -  |  .  | system.  The X coordinate refers to how far
       /    /    /    /    /  along the horizontal you are, the Y referring
      /    /    /    /    /   to the vertical.  Thus, there are seas on
-1    |  -  |  -  |  .  |  .  |    example map at  5,-1  7,-1  0,-2  8,-2
     /    /    /    /    /    5,-3  7,-3  0,-4  and 8,-4.  Negative X is
    /    /    /    /    /     to the left (to the East) of 0,0 just as
      0  1  2  3  4  5  6  7  8    in your high school math courses.  However,
                       negative Y is above (to the North of) 0,0.
          Figure 3          This is different from high school math.
     Example of an Empire map      Why the maps have coordinates in this way
                       is one of the great mysteries of Empire.
----------------------------------

     Figure 4 below is a real map of Empire, in its real size and form.
     Figure 3 is "zoomed in".  Note that the '?' marks on the right part of
     the map belong to a neighboring country.  In this figure all wilderness
     type sectors have been designated into something other than a
     wilderness There are several mountains, and a lot of ocean visible as
     well.

-------------------------------------------------------------------------------

     As you can see, there are a wide variety of sector types in Empire.
     However, until your country becomes populated the most useful sector
     is the highway ('+'), for it allows you to move things around easier,
     even if the highway has only begun being constructed
     (ie, 0% efficient).

Summary: Empire maps are based on a simple hex design, with the movement
      keys based similarly around the letter h on standard keyboards.
      These movement keys are a basic tool in Empire and must be learned.

Chapter 5 :-: The beginning phases of Empire.

     Typically a game starts with a `speed' phase. If it does not, then
     initial play can get boring quickly.  A `speed' opening also demands
     more time for the period when the updates are frequent, but hopefully,
     that will be balanced by your efficient country and the less time
     spent running it when your classes/real life demand more time.

     There are several opening strategies for Empire players.  I am going
     to go through a few of them here.  If you feel you can make a better
     strategy feel free to do so.

     Basically, all strategies for the opening phases revolve around a
     few basic ideas.  First, you want to secure as much land for yourself
     as possible.  Secondly, if you share an island with some other person,
     you want to leave yourself in a strategically advantageous position
     against your opponent, optimally to surround him/her before s/he breaks
     sanctuary.  These two ideas are the most important things to consider
     prior to the first update.  There are other things to consider, which
     will be reviewed later.

     It is highly important for you, the player, to begin playing the game
     as soon as the game begins.  If you do not, you risk being surrounded
     before the first update.  Furthermore, not breaking sanctuary prior to
     the first update can cost you a great deal in terms of population
     growth and the establishment of your economy.

     Some players will use tools, which are reviewed in chapter 14, to
     break sanctuary and occupy land from the beginning.  There are other
     means to aid your land occupation as well.  If you have a programmable
     terminal, or terminal program, you can program a key to contain a
     particular command such as "explore civ 0,0 1 jjjujuuu".  This could
     be a path along a line of land that you have already occupied, and
     wish to expand beyond.  If you had to repeatedly type in that command
     and path you would take a much greater amount of time to occupy land.
     This can also be done through X windows, using the mouse and cut/paste
     capabilities.

     There are a few different theories on how to explore out from your
     sanctuaries to claim as much land as possible for yourself.

     In the following maps, the square island shown is entirely wilderness
     except for the two sanctuaries in the middle.  It is important to note
     that prior to exploring the entire island, the only thing you would
     be able to see on your map would be this:

User's Guide to Empire                                  22

       - - - - - - -
        - - - - - -
         - - - - -

     It is your job to explore the island, while occupying, or securing for
     yourself, as much land as possible.  Note that for the sake of
     simplicity I have not placed another country on this example island.
     If a sector is a "+","c", or "s" it is an occupied (by you) sector.
     If it's a "-" it's a wilderness sector, and if you can move into it,
     it is unoccupied.  This is an important piece of information.  If you
     can note move into a wilderness sector it means that it is occupied by
     another country.  Note that "." are seas, as indicated in chapter 5.
     The basic commands to complete this exploration are 'explore' and
     'designate'.  Learn about those commands either from chapter 4 or
     the game before attempting these theories.

     First, I show the entire island prior to your breaking sanctuary and
     exploring:

     Next, I show theory 1, occupying in a concentric circle.
     Note that once you have broken sanctuary (using the 'break'
     command) that your two sanctuary sectors immediately become
     capitals, with your real capital at 0,0.

     Now, 84 sectors have once again been occupied.  However, an additional
     56 sectors are now within the borders of your country.  Thus, securing
     a total of 140 sectors for yourself.  The disadvantage?  You have three
     lines of occupation ( the "+" sectors) between the center of your
     country and unsecured wilderness.  In theory 1, the same number of
     sectors provides for 4 lines for most of the country.  Another
     disadvantage is that it costs more mobility to use theory 2.  The more
     lines of occupation you have between the central areas of your
     country and the unexplored wilderness or an enemy the easier it is
     to defend your country.

     A third theory is the idea of coastal occupation as a means of securing
     a large island.  The idea being to secure the land immediately around
     you and then explore in one direction until you find seas, and then
     proceed to occupy the coast:

     Here, once again, 84 sectors have been occupied.  In addition, 179
     sectors of wilderness have been secured, ie cut off from another
     country.  This brings a total of 263 sectors occupied or secured.
     This is obviously impressive.  However, it has its drawbacks as well.
     If there was a country bordering this country, that country would
     need only to attack and occupy one of your sectors and then they
     could explore into all of the "secured" sectors.  In addition, there
     are only 2-3 lines of occupied sectors between the borders and the
     center of the country.  This also costs more in terms of mobility than
     either theory 1 or 2.

     The next section contains a strategy submitted by Scott Yelich.  Scott
     adheres in this summary to theory 1 as his method of exploration:

User's Guide to Empire                                  25

  "Designate one of the two initial [sanctuary] capital sectors to
an agricultural center.  Then move a civ out from either sector to
either 1,-1 or 1,1 and designate it a +.  Then, I continue to move out
one civilian at a time from both of my initial sectors.  Only move
the civ one spot into the wilderness and then I designate that sector
as a highway (+).  Then, do a map to see if there is anything
especially interesting... such as, a mountain, more land or ANOTHER
PLAYER.  Of course, Only do that map at certain times... it's not
necessary to do a map after EVERY explore since explore will show you
a one sector radius!

[Editor's note: exploring with one civilian across a wilderness sector
takes .8 mobility.  Across a highway, even a 0% highway, it will cost
only .2 mobility.  Thus, the reason for designating new land as soon
as you occupy it.  You will conserve mobility if you only explore into
lands bordering your new highways.]

  "Here is where quick action comes into play.  If you spot any controlled
sectors (?) or a (-) that can't be entered (if you can note move into the
sector it is occupied by someone else! hurry!), try to make a boarder as
quick as possible by following the pattern above... move one civ, look,
repeat.  If you don't find any controlled sectors, simply [try] to
AVOID MOUNTAINS at ALL costs...  especially during the first couple of
updates.  Typically, from 30 to 70 sectors can be grabbed this way
within the first minute or two.

  "To sum up, the strategy for this is: 1) You want to see who is out there,
2) You want to see what land is out there, 3) when you take more sectors
during the initial updates, you will get more mobility each update
(typically 8, 'version' will tell...).  Anyway, the more sectors you grab
with the first update, the more you can grab the second.  It's like an
exponential function."

     This next section is a strategy submitted by Geoff Cashman.  Geoff
     adheres in this summary to theory 2 as his method for exploration:

  "The basic strategy of moving one sector into the wilderness and then
designate them with a command such as this:  designate #1 ?des=- +  which will
designate all sectors in realm #1 that are wilderness into highways, is a
common one.  Using it wisely is not always done.  My personal method is to
expand only in a few directions, ie 3-6 different directions from your 0,0 2,0
area.  The idea here being to make "spokes" of exploration radiating out from
your 0,0 and 2,0 area.  Using this method, you can use less mobility and see
more land though not actually own more land until after the first update.
Another advantage is you might reach an opponent before s/he reaches you.  A
weakness is that an opponent can explore inbetween your spokes.  If I feel
this is possible inbetween two spokes then I connect the spokes via concentric
(on 2,0 0,0 ) arc several sectors out from the 0,0.  If you do not use this
method, then you would use up all of your mobility to achieve the same number
of sectors by the second update.

User's Guide to Empire                                  26

  "Why save mobility?  Mobility in the 0,0 sector is especially critical.
The reason is because the 0,0 starts out with 999 civs.  If a sector has
999 or more civs it will not give birth to more civilians.  Half of the
battle in winning Empire is population explosion at the beginning of the
game...ESPECIALLY if you get involved in a low tech war with a neighbor
early on.  More population means more resources mined, more supportable
military, and more taxpayers.  If you are going to be a tech producer then
it may be desireable to limit population, but early on I do not recommend
it.  So, with 999 civs in your 0,0 sector you need to be able to move out
many civs (depends on the number of ETUs per update (see the version command)
as to how many you should move out, see number of births per 1,000 civs per
etu in the version command).  Thus, my strategy is slightly different.
I concentrate on getting a 100% highway built at 1,-1 or 1,1.  Why those
sectors?  because I can then use the mobility in 1,-1 or 1,1 to move civs
or products into 2,0."

     The use of the third theory requires a player with some experience
     to deal with its shortcomings.  For the beginner, I do not recommend
     it.

     The following was submitted by another player to point out their means
     of establishing their production and the beginning stages of their
     economy:

"Setting up a distribution network, even with inefficient warehouses, is
fairly critical early on.  If you starve civilians in the beginning of the
game, you will fall behind in production.  It is not uncommon to lose
contact with the game for a day or more due to net failures.  Do not
depend on your capability to connect to the game to feed your civilians.

"Some people never leave their 0,0 or 2,0 designated as a capital during the
beginning of the game.  They check the resources in 0,0 and then determine if
it's suitable for being a mine or a gold mine.  If neither, then they designate
2,0 into a mine.  If mine, then 2,0 becomes a gold mine.  Using this method
they can get maximum production from their civilians that are essentially
trapped for the time being in their 0,0 and 2,0 sectors due to lack of
mobility.  Note that in doing this that you must conserve BTUs.  Having
a 0% efficient capital somewhere else will cause a lack of production of
BTUs.  You must be careful not to run out of BTUs completely, or it could
cause you a great deal of grief.

"NOTE: IT IS EXTREMELY DANGEROUS TO LEAVE A CAPITAL ON THE COAST AFTER
ANYONE PRODUCES A BOAT.  Until that time, a capital on the coast is
an advantage in some ways.  It is easier to defend (less places that
it can be attacked from).  You MUST get some civilians into the capital
at -2,0 (about 50) before the first update along with some food.
In general, your capital will not produce BTUs for a while, but neither
do you need them for a while.  However, leave your 0,0 sector as your
capital until JUST prior (like 2-4 minutes, make it 10 to be safe) to
the update.  Does this all sound complicated?  Yep.  But it works.

User's Guide to Empire                                  27

"After the first or second update I will occupy the remaining wilderness
that I can see, using the mobility from the sectors that I explored into
in the previous update.   I will then continue to move civs out of 0,0 and
into 1,-1 or 1,1 (the highway that I am trying to make 100%) and move from
there.  If I am not going for tech production then I don't need the library
or parks (you can still make education, it helps in some regards, but for
the most part you don't need it if you are not going the way of tech.

You can then pretty much do as you please and work towards the goals you
think are reasonable for your country.  "

     One matter that can not be overlooked by any player is the simple
     fact that people need food to survive.  If a sector has less than
     60 people in it total, including civs, soldiers, and uws, then it
     will not starve.  But if after the update it has more than 60 total
     people will starve.  Make sure to feed your people!

     Ultimately, you want to take over every sector on your island.
     If you have neighbors on your island, you will probably have to share.
     Just try to get a bigger portion of it than your neighbors do.

Summary: There are several basic ideas expressed in this chapter:
      1) Break sanctuary as soon as the game begins.
      2) Secure as much land for yourself as possible.
      3) Use your civilians efficiently.
      4) Do not allow your 0,0 sector to have a lot of civs in it.
      5) Get a distribution system set up early (explained later).

Chapter 6 :-: Diplomacy.

     It's your own ruin or success.  One of the best players of the game
     (who shall go un-named) has had severe problems due to lack of skill
     in diplomacy.  Remember, there is another person on the other end of
     that telegram.  They are human like you are, and like to be treated
     like it for the most part.  There are jerks, and there are non-jerks.
     Determine for yourself and go along with what you think is best, but
     remember, it is ok to lose a few battles so long as you win the war.
     A diplomatic loss can be an overall victory.

     One of the most powerful weapons in the game is information.
     What types of information can you use to your benefit?  Information on;
     the locality of other countries, the plans of opponents, the trading
     going on between certain countries, etc.  There is also a very powerful
     tool right here in this document: how to play the game well.  There
     was a classic case of a country (myself) who accidentally announced
     his attention to attack a bordering country.  The bordering country
     happened to be on, an began an attack.  The attack stalemated for the
     most part because of the obvious inexperience of the person running
     that country.  I offered information to him on how to play the game
     better in exchange for his surrender and some other terms of agreement.
     I turned a horrendous diplomatic mistake into a diplomatic success
     within two hours.  This is obviously the rare case (surprised me too),
     but is a good example of the power of information.

     Another aspect of diplomacy is style.  You project a style in your
     telegrams and announcements whether it is intentional or not.  If
     people like you they tend to side with you more than the next guy.
     Of course, if you are a jerk but a powerful one people tend to
     reluctantly side with you.  Then again, they are more likely to
     backstab you.

     While I am on that subject:  Backstabbing is a bad idea in general.
     It leads to distrust of many players with regards to yourself and tends
     to give yourself backstabbist's wrist if you do it too much.  Even if
     you change your country name from game to game people tend to pick
     out who the major jerks are and their previous names or even net
     addresses.  Trust is important.  If you have allies you can trust
     implicitly you will sleep a lot better at night and also have people
     who you can trust to run your country for you while you are away for a
     few days pursuing real world goals.  If you are going to backstab
     someone crush them while you can and make sure their allies can not
     get at you.  Furthermore, make the world see that the person was a
     fool for trusting you in the first place (like, due to previous war
     or some such).  Sometimes, that extra attack you get without
     interference from automatic defenses due to a declaration of alliance
     with your opponent can be critical.  You can also map an opponent
     country if you are allied with them and they will never know it.
     Thus another good reason why you should be trustable and can trust
     other close allies.  Having allies is important, especially
     in the current market games.

A)  What is diplomacy?
     The dictionary defines diplomacy as "1: The art and practice of
     conducting negotiations between nations.  2: Skill in handling
     affairs without arousing hostility."  The second definition may
     not be entirely accurate in that in Empire, diplomacy can sometimes
     be used to cause battles, rather than avoid them, to gain a particular
     end.  I will go into this later.

B)  What purpose, diplomacy?
     Since Empire is a multi-user game the diplomacy side of the game
     is one of the main factors inherent to its playing.  Being able
     to interact with other players, make bargains, treaties, alliances,
     sales, war, etc. leads to an incredibly variety of possible
     scenarios among various countries.  In asking, what purpose is
     there to diplomacy, it must first be realized that diplomacy in
     the game of Empire is virtually unavoidable.  To what degree
     you involve yourself in diplomacy is the true measure.

     Diplomacy can be utterly disastrous for you.  It can also be
     very beneficial.  It can also be a mediocre tool that goes mostly
     unused.  If you master the techniques of diplomacy you will find
     yourself with a very valuable and powerful tool.  If you fail
     at grasping the basic concepts of diplomacy, then you may find
     yourself the quick victim of a diplomatic trick.

C)  General types of relations amongst nations in Empire
     1) No contact.  The two countries have never been in contact.
     2) Allies.  Several types:
          a) Old friends, or local site friends.
          b) People whom you trust more than other people
             in the game, but are not entirely comfortable with.
             Nevertheless, you ally with them for lack of allies.
          c) Enemy allies.  People whom you ally with whom you
             intend to attack.
          d) Undeclared allies.  You conduct a lot of business with
             the country, but you do not officially declare your
             alliance.
     3) Hostile.  Generally speaking, any country who is unfriendly
        towards you.  May not necessarily be declared hostile.
     4) At war.  If you have not figured out what this means, stop
        reading, never play Empire, and go back to elementary school :-)
     5) Neutral.  The broadest category.  You've dealt with this person
        but have not decided one way or another your relations.  It might
        be a person from a previous game or a total unknown.

d)  Types of diplomacy
     1) Active diplomacy
          You interact with the country on a very high level.  Whatever
          their relations with you, a lot of correspondence is going on.
          This is probably the easiest form of diplomacy to invoke.
     2) Passive diplomacy
          Low level contact only.  In essence, you do not work with
          this country.  Some goals served by this:  Country in question

User's Guide to Empire                                  30

          learns little about you; Country in question may give you more
          info than you give him or her; etc..
     3) Indirect diplomacy
          Diplomacy through a middle country to another country.  This
          is most often seen in situations where a known friend is an
          ally of a country you want to be allied with.  You attempt
          to use your friend to convince the prospective ally to ally
          with you.
     4) Median diplomacy
          Being the middle person in a triad or more of allies that
          may not be already allied.  This can be a VERY dangerous
          position to be in.  The other sides of the triad or more
          may have certain expectations of you, which go against what
          another country may want from you.  This is essentially
          sitting on a fence.

E)  Some goals that can be achieved through diplomacy:
     1)  Getting another country to ally with you so that you can
         overfly his country at will without planes scrambling.
     2)  Getting two countries whom you dislike to go to war against
         each other.
     3)  Getting another country to perform an act that is beneficial
         to you or your allies.
     4)  Getting a reduction in price of certain commodities or articles
         from another country.
     5)  Gaining an ally.
     6)  Assisting in destroying an enemy.

     One of the most dangerous means by which diplomacy can be used was
     written about in the book "Red Storm Rising" by Tom Clancy.  If you
     have not already read this book and you are an Empire buff, it is
     strongly recommended reading.  This method is referred to as "The
     Maskirovka" or "Masquerade".  It is often referred to as the "big lie"
     by the victims of this trick.  Essentially it works as follows:

     a) You wish to attack another country, but would like to have things
        sightly different before the attack begins.
          o  You may want that person to be your ally before the attack
             so you can overfly him/her without being shot down.
          o  You might want to get him/her to give you a loan prior to
             your attack.
          o  You might want them to move their fleet off in another
             direction or in closer to your forts.
          o  You might want them to give you certain materials of war
             that you can use in your attack against them.
        All of these things and much more can be accomplished with
        the concept of maskirovka.  Decide what you want to achieve.
     b) You set out to give the impression to the target country that you
        are in a particular state of matters.  This can be accomplished
        in various ways depending on what you are trying to achieve.
        You can have another country attack you for instance to make it

User's Guide to Empire                                  31

        appear that you need military arms or supplies to hold them off.
        This is one small example of what can be done.  Ensure that the
        image you are presenting can ultimately lead to getting what you
        want to achieve accomplished.
     c) You must be convincing in your impression.  Use all means reasonable
        to ensure the target country is getting the right image.  Using
        e-mail with collaborating countries to coordinate such matters
        is often best.
     d) As you begin feeling that you have achieved the correct image,
        begin asking the target country for whatever it is you are trying
        to achieve.  Do not come right out and say it.  That may cause
        the whole trick to collapse on you.  Approach it sideways so to
        speak, and try to get the target country to offer whatever it is
        without you directly asking for it.
     e) If the country agrees to the transaction of events you are seeking,
        all is well and good.  You have achieved your goal.  Keep in mind
        that if you have played the maskirovka well, you have not yet
        committed yourself in any particular direction with any sense of
        strong commitment.  At this point, you can always back down from
        your further goals for which the maskirovka was designed to help.
        The maskirovka at this point will have given you a more favorable
        situation without having committed yourself.  It may also have
        enabled you to see more into the mind of your opponent, often
        a valuable commodity.
     f) If you have failed in your maskirovka, you may still have made
        some gains.  You again might know more about your opponent than
        before.  You might have reached some of your goals that the
        maskirovka set out to accomplish.  Lastly, you have not committed
        yourself in any particular direction, yet you have tried to
        enhance your position.  Not a bad proposition.

     There are many variations to maskirovkas.  The guides listed above are
     very general at best, and are meant more to give you an idea of how to
     build a plan for maskirovka than anything else.

     Chess players who have ever played in matches or tournaments will
     probably feel right at home in scheming a maskirovka.  You must try to
     get into the mind of your opponent, understand what s/he sees from
     his/her vantage point and get a feel for how you think s/he will
     respond.  You must think as if you were your opponent.  Understand
     their vantage point as best as you can.  Do not think of what you
     would do in a given situation, think what they would do.  Think
     consequences to every action you can take.

     This usage of diplomacy is "active diplomacy", sometimes mixed with
     "indirect diplomacy".

     Another oft seen ploy of sorts is one in which you befriend a dying
     rich country.  They may be on there way out, and there may not be a
     whole hell of a lot you can do for them.  However, befriending them
     towards the end may bring you gifts of money or lower market prices

     You can be sincere, or you may chose not to be.  Sometimes a dying

     country has no friends to whom they will leave their money.  If your
     the first to show sympathy, they may be willing to give you much in
     return.  This is an active form of diplomacy, but is rarely seen
     except after a long period of passiveness relative to that country.

     Posturing.  Probably the most common form of diplomacy.  This basically
     means presenting an image to a possible attacker that you are more
     capable than you appear.  In general, people tend to believe it.
     Consider the simple fact that generally speaking a good Empire player
     spends a lot of time working on his or her country.  Then, let them
     believe through posturing that they are at a greater risk than
     they actually are.  They may tend to get possessive about their
     country and not want to risk its destruction and the eventual loss
     of so many sleepless nights and hours building the country in the
     first place.

Summary: Diplomacy is a powerful tool.  Some players consider it the
      most powerful aspect of the game.  In many ways that can be shown
      to be true.  However, do not let other facets of your country
      decline and spend a huge amount of time building an excellent
      diplomatic situation.  The success or failure of diplomacy depends a
      great deal on the other players perception of your words.  If your
      diplomacy fails, you may find that you will be forced to back up what
      you say with military force.

Chapter 7 :-: Setting up your defenses.

     There are various means of "automatic" defense that Empire employs
     against enemy invaders.  These can be outlined in three major areas:

     1: Home air defenses

          Empire has numerous planes and plane capabilities.  The higher
          your tech level, the better the planes you can build.  For
          automatic defenses you are concerned with planes that have the
          "intercept" capability listed next to them in the command,
          'show planes c'.

          Generally speaking, as some games diverge from this list, the
          planes that have intercept capability are:
               a: Fighter 1       (also has VTOL capability)
               b: Fighter 2
               c: Escort 2        (in SOME games)
               d: Jet fighter
               e: Jet fighter 2   (also has VTOL capability)

          These planes are based out of airbases (except for the VTOL
          planes which can scramble from airbases and non-airbase
          sectors) and will automatically intercept incoming enemy
          planes.

          notes: 1: Planes will only scramble if there is petrol in
                 the sector they are scrambling from.
                 2: Airbases must be at 60% or better efficiency to
                 scramble.  This does not apply to other sectors
                 from which VTOL planes are scrambling, nor does it
                 apply to VTOL planes in airports.

          In this version of Empire it is VERY important to have a good
          home air defense network.  Having a great many planes with
          intercept capability without proper planning is not a good
          defense.  You must learn to use the planes wisely.

          Hints for good home air defense:
          1:  Have airports within intercept range of each other.
              A plane's intercept range is 1/2 of its range indicated
              in the command 'show planes c'.  For example:

User's Guide to Empire                                  34

                    Figure 10
            Results from 'show planes capability'

-------------------------------------------------------------------------------

              In this list of planes, only the Sopwith Camel plane is
              capable of interception.  It has a range of 6, and thus
              it can intercept enemy planes up to 3 sectors away from
              the sector it is based in.  Have your planes based in
              sectors that are three sectors away from each other.
          2:  Always have a substantial number of military in your
              airports.  It is all too easy for an enemy to track
              down your airport and capture it, thus possibly destroying
              all your planes, and in the very least taking them
              from you.
          3:  Ensure that all sectors that you have planes based in
              have a sufficient amount of petrol for them.  Note that in
              the above figure, the Sopwith Camel uses 1 fuel per
              mission.  Thus, having 10 or more petrol per Sopwith
              would be sufficient.
          4:  Do not base your entire defense on non-VTOL capable
              interceptors.  If you do, then your enemy can remove
              your air defenses just by taking out your airports.
              Sopwith Camels (Fighter 1s) and Jet Fighter 2s are
              the VTOL intercept capable planes.  Sopwith Camels
              generally become useless for intercept duty as the
              game wears on.  After all, a paper airplane can not
              put up with cannon fire from an F-15 for very long!
          5:  It is a good idea to have each sector in your country
              covered by at least two airbases (or non airbases from
              which your are basing VTOL planes).  This makes it more
              difficult for your enemy to locate where your airbases are.

     2: Forts and guns

          Forts will automatically fire on any enemy army units that
          attack land of the defending nation, assuming that the guns
          in the fort have the range to reach the aggressor.  This
          also assumes that the fort has shells and military.

          Fort gun range is determined by multiplying the number of guns
          in the fort by the technology factor of the nation.  This
          number can be found in the nation report [see command: nation].

User's Guide to Empire                                  35

          Here's an example of calculating your gun range:

                    Figure 11
                Results from a 'nation' report

--------------------------------------------------------------------------------

          To calculate the gun range, multiply the number of guns in
          the fort (up to a maximum of seven) by the number listed in
          "Technology factor" which is shown in this figure as 40.66.
          Then, divide the resulting number by one hundred and that
          is the number of sectors away the gun can fire at.  In this
          case, if you have seven guns the resulting range is 2.85
          sectors.  Effectively, the fort can fire just short of three
          sectors away.

          There is an additional aspect of forts which make them
          useful as defensive sectors.  Military forces inside of
          a fort have four times the defensive factor of military in
          most other sectors.  Ie, 100 soldiers in a fort is equal to
          400 regular troops if they are defending the fort.

          Also note that forts can not be taken by paratroops dropped
          from planes.  They can only be taken via amphibious assault
          and overland attack.

          Forts are generally useful along your border sectors early
          in the game and later on in the game throughout your country.
          Ensure that they each have sufficient (seven or more) guns
          and shells each, when you are able to devote that many guns
          and shells to them.  Forts are sometimes very critical when
          your country is being over run.

User's Guide to Empire                                  36

     3: Naval support

          Your navy will defend itself if it has the capability to do
          so.  Ships do not automatically come with guns when they are
          built; they must be provided with guns and shells by loading
          them onto the respective ship.  Most ships have the capability
          to fire guns.  Should a ship of your nation be attacked, it
          will defend itself if it can.  In addition, ships within range
          will also retaliate.  Note that submarines will *not* fire
          no matter how often they are fired at.

          Ships will not defend your land sectors.

          If ships are attacked from the air, they will fire their
          anti-aircraft guns (which are the same as your regular guns,
          and again are not automatically installed upon their
          construction).  Anti-aircraft guns on ships are pretty much
          worthless on defense.  Additionally, if enemy planes fly
          over your ships but do not attack those ships, your ships
          will not fire on them.  Thus having a line of ships as
          radar pickets will not work.

     In addition to these three major modes of automatic defense, there
     are a few more minor ones.

     Any gun in any sector of yours that is overflown by enemy planes
     will fire on those planes if it has shells, guns,  and military
     available.

     Military in any sector of yours that is attacked will automatically
     fight back to the best of its ability.  There is no such thing as
     retreat in automatic military fighting.  In addition, there are three
     sectors which multiply the effectiveness of military within them.
     We have already mentioned forts in this capacity, in that they
     multiply the effectiveness of troops within them by four.  Capitals
     and Banks multiply troops effectiveness by two, when on the defensive.

     Also note that Capitals and Forts, as previously mentioned, can not
     be taken by airborne paratroopers.  Neither can mountains.

     Lastly, should sectors of yours be taken, the enemy will have to deal
     with your patriotic guerillas.  Guerillas will attempt to retake
     sectors from the enemy every update until they are defeated (which
     takes some time).  They are large in numbers, but have been known to
     reach strengths of a hundred or more soldiers, though this is rare.
     If they can not hope to retake the sector they may try to blow things
     up in the sector the enemy has conquered.  This results in loss of
     efficiency to the sector as well as reduction in the work capability
     of the sector.

     You have *no* control over your guerillas whatsoever.  They are
     completely automatic.  Should guerillas win a sector back from your
     enemy then the surviving guerillas become members of your regular

User's Guide to Empire                                  37

     military, and you can use them as such.

     If your guerillas manage to take a sector back behind enemy lines
     it is possible for you to enlist reservists in that sector.  In
     so doing, you may throw a major thorn into the side of your attacker.
     This is a major reason for maintaining a large amount of reserves.

Summary: Automatic defenses in Empire are a critical part of every country.
      If your country can not defend itself then you can expect to be
      quickly over run.  Use the automatic defenses described in this
      chapter, and you will become a more difficult opponent.  Remember
      the three basic areas of automatic defense.  In addition, keep in
      mind that your airforce is probably the most important component of
      your automatic defenses.

Chapter 8 :-: Nuclear warfare.

     Nuclear war in Empire is not currently the dreaded end of the world
     doomsday machine it is in the real world.  Nuclear weapons in the
     standard release of Empire have no fallout, no radiation, no dust
     clouds, etc.  Nuclear weapons in Empire are essentially big
     conventional bombs.  They are "clean" weapons in that the only
     difference between them and conventional bombs is that they are
     bigger and create nuclear wasteland.

     As such, a nuclear war is much more survivable.

     There are several things that you need in order to wage nuclear
     war against an enemy.  First, you need the nuclear warheads themselves.
     You will also need a missile or plane of sufficient type and range to
     launch the warheads on.  Lastly, you need to have target information,
     ie where to land the nuclear warhead to cause the damage you want it
     to cause.

     Next, you need to decide if it is worth the cost to wage a nuclear
     war.  Should the enemy country know where you are, and have the means
     to retaliate in kind, s/he will most likely do so.  This can cause
     grave damage to your own country, and eliminate any gains you may have
     achieved by beginning a nuclear war.

     There is also the large chance of great diplomatic cost.  Most
     countries do not tend to favor countries that rely on nuclear weapons
     for victory, since it is the "easy" way out.

     However, the scenario that the beginner needs to be most concerned
     about is being the victim of a nuclear attack.  Most beginners never
     come close to achieving enough strength to have an effective nuclear
     force.  It may take several games before you become practiced enough
     to maintain an economy and military that is capable of having the
     resources, etc. necessary for such a force.  Nuclear weapons can be
     bought from larger powers, however the beginner still rarely tends
     to have these.

     In the event that you are attacked with nuclear weapons you need
     to take immediate steps in order to ensure your survival.  You must
     first decide if it is in fact worth it for you to continue.  Most
     nuclear attacks are survivable.  In many cases, you may be hit by
     only one warhead.  Depending on the size of your country, a small
     number of warheads hitting you is survivable.  This all assumes the
     warheads are of the 5mt variety.  5mt warheads create a wasteland
     that is 5 sectors long from left to right.  3mt warheads create
     wasteland that is 3 sectors from left to right.  Diameter in both
     cases is the same north-south as east-west.  These are the only
     nuclear weapons that can really create serious problems for you.
     Other nuclear weapons cause problems, but are essentially nuisances
     that can be easily overcome.

     The following is a map of your -20:0,-10:3 region.  You have been

User's Guide to Empire                                  39

     hit with a 3mt nuclear warhead at your sector -12,-6.  It wastelanded
     7 of your sectors and damaged nearly the entire area.

                    Figure 12
            Map of area hit by 3mt nuclear warhead

--------------------------------------------------------------------------------

     Here is a basic outline of what you will need to do should you be hit
     with one or more 3mt or greater warheads:

     1: Get food to the people in areas that need food.  Especially areas
        that are partially or totally cut off from the rest of your country.
        ON THE MAP ABOVE:  This would probably be necessary for all sectors
                     east of -12 and/or north of -4.

     2: Distribution routes *will* be cut off by a nuclear hit.  Redo your
        distribution routes around the nuclear wasteland areas.  Make sure
        that your new distribution center has enough food to feed the people
        you are trying to support with it.
        ON THE MAP ABOVE:  This would probably be necessary for all sectors
                     in the region.
     3: Move people into the area affected by the blast.  Get highways in
        the area back up to efficiency as soon as possible.  This will
        allow for increased movement in the immediate area of the blast
        which could be critical to the survival of the people in that area
        as well as defense of the area.
        ON THE MAP ABOVE:  You will probably need to restructure your
                        highway system in the region.  Move people in
                     from the south-east (off the map).
     4: Lastly, try to get production back online in the area.  This is
        not as critical as the first three things.

     Those are the essentials for recovering from a nuclear blast.  The

User's Guide to Empire                                  40

     first three items should be done as soon as possible top to bottom,
     ie number one is priority one.

     There are also defense considerations after you have been hit by
     a nuclear blast.  Your air defenses in the area might be wiped out
     which would allow your opponent to take over your land in that area.
     There are also steps you can use to shore up your defenses in the
     area while you are getting the area back on its feet:

     1: Enlist military in the region.  Looking at the map in figure 12,
        You might do something like:

     [23:210] Command: enlist -20:0,-10:3 -25

        That would enlist military in the region so that every sector had
        at least 25 military in it.  Note that you can only enlist half of
        the population in a sector at one time, but you can enlist in the
        same sector over and over again.

        Doing this would hamper an enemy's progress should they attempt a
        paradrop assault in the region.

     2: Move undamaged or nearly undamaged VTOL fighter planes from the
        south-east (off the map) into the area.  Do not put them on
        the airbase.  Provide them with petrol as well.  This will
        shore up your air defenses which were damaged by the blast.  It
        will also make it much more difficult for an enemy power to attack
        by air in the region.

     3: Move guns and shells into the forts on the map if they are not
        already there.  Make sure there is at least 7 guns and a lot of
        shells in each fort.  Also make sure there are substantial military
        forces in each.  This will help prevent extended military action
        on land by an enemy.

     4: Move naval forces into the region if possible.  This will help
        to prevent amphibious assaults.

     If you do all of these things, recovery from the blast will not
     take long at all.  These things will minimize the effect of the
     blast and get the area back on its feet again.

     Do not be dismayed by loss of resources etc.  You *can* recover.
     I have been a victim of nuclear war probably half a dozen times,
     and so far have found only one case in which I was crippled by
     the effects.  My entire homeland (of ~100 sectors) was
     wastelanded except for less than 10 sectors.  No, I could no
     longer hope to win the game, but I did hang on long enough to
     purchase a nuclear warhead and missile and attack the person
     who nuked me.  Doing something like this will make the player
     who nuked you respect you more in future games, and consider
     the consequences before pushing that button.

User's Guide to Empire                                  41

     It has become fairly routine lately for games to end with a world
     wide nuke-off.  Generally speaking, nations having nuclear weapons
     threaten the world with destruction if they are not acknowledged
     as victors.  Other people protest of course, and nuclear war happens.
     A game that has taken eight weeks to evolve to that point can be
     destroyed in less than an hour in the hottest nuclear wars.  This
     of course does not lead to any clear cut winner, and is rather
     pointless but people do it anyway.  It is after all, a game, and
     people want to have fun.  Nuclear war, to many people in Empire,
     is fun.

Summary: Do not be demoralized by a nuclear attack.  Powers using nuclear
      weapons expect their opponents to get demoralized. Recovery from a
      nuclear attack of larger degree is possible as well.  It takes
      perseverance and sometimes hard work.  Don't be dismayed by mass
      starvations.  Populations can recover if you work at it.  Your
      reputation may be greatly improved if you do recover from a nuclear
      blast.

Chapter 9 :-: Technology.

     By most people's definitions technology or the means to purchase
     technological weapons from another country is one of the most
     critical elements in doing well in Empire.

     Having technology allows you to:
     1.  Have increased ranges on your land based radar.
     2.  Build higher capability planes.
     3.  Build more advanced types of planes.
     4.  Build higher capability ships (not as great an effect as in planes)
     5.  Build more advanced types of ships.
     6.  Build bridges.
     7.  Build nuclear weapons.
     8.  Have increased ranges on your guns in forts.

     Thus, having a high technology country is a very useful thing.
     However, attaining a high technology level is very difficult for
     the beginner.  Running a country that has an economy balanced well
     enough to produce technology at a rate sufficient to stay in the
     technology race is a very difficult task, even for players who are
     more experienced and/or have a lot of allies supporting their
     economies as well.

     Producing tech is expensive.  It costs a lot in terms of money
     and materials.  Not only do you have to produce tech, but you
     have to educate your people to a high enough degree that tech
     production can be done efficiently.  Doing this takes a great
     many light construction materials (lcms) for education, and a
     large amount of oil, gold dust and lcms for tech production.

     It is not uncommon for tech nations to be one of the smallest
     and poorest nations around.  Most of their time and resources
     have to be devoted to tech production rather than ships for
     exploration and military to defend outlying colonies.

     Do not fantasize.  If you are a beginner, forget about producing
     tech no matter how good you think you are.  You will be wasting
     your resources in doing so and crippling your economy while other
     countries will run far far ahead of you in production.

     In general, until you have played a few games it is far better to
     purchase high technology items from other players.  Diplomacy,
     discussed at length in chapter 7, is an effective tool for
     purchasing technologically superior items.

     Should you decide to run tech, there are several things you should
     know.  If you are able to take these into account, and balance these
     factors against each other you may be able to produce tech at a
     sufficient rate to stay with the leaders.

     Education is important to produce tech.  You have to have an
     education level of at least five before you can produce any.  However,

User's Guide to Empire                                  43

     an education level of five will produce tech only in an inefficient
     manner.  The higher your education level, the more efficiently tech
     will be produced.  This means that a single tech center can produce
     more tech per update, and cost you less in raw materials, though it
     will cost the same per unit of tech produced.  The savings in raw
     materials is critical.

     Some countries feel it is better to keep your population low when
     they are planning on having a high education level.  The reasoning
     behind this is that it takes less effort to educate a small number
     of people and costs less money as well.  There is a bad side to this
     plan though.  With a small population it is hard to produce things
     in large quantities, and exploring into and occupying new lands is
     very difficult.

     Technology production demands a large amount of resources.  Especially
     oil.  However, the higher tech you are the more oil you are able to
     refine per amount of crude oil in the ground.  Thus, it is better to
     only take out of the ground what oil you need to keep your country
     running, and leave the rest for later on when you have higher tech,
     and get more per barrel of crude.  Thus, if you were to do the
     following:

     [23:512] Command: resource 4,0

     You might see that your 4,0 sector has 100 units of oil in the ground.
     At tech 0 you'll be lucky if you get 500 barrels of oil out of that.
     However, at tech 100 you will probably get somewhere around 700-750.
     That's a big difference.  So, only take approximately what oil you will
     need for each update out of the ground, and leave the rest for later.

     Tech production also requires gold dust.  Gold dust mining is not
     affected by tech like oil wells are.  Thus, mining the gold dust
     right away or saving it later has no impact on how much is produced
     per unit of gold dust in the ground.  There are other considerations
     though.  If you have a lot of gold dust sitting around in your
     warehouse or other storage place, other countries will see via the
     power report that you have a lot of dust.  If they are low on dust they
     just might look at you as a possible target.  So, if you are going to
     mine a lot of your dust right away you might want to consider putting
     a good portion of it into banks where the dust gets converted into
     bars, which will give you more money per update.  This especially
     applies to the Kent State version of Empire, where you can grind up
     your gold bars into gold dust at a loss of 20% of the original amount
     of dust put into the bars.

     Uncompensated workers are also useful for tech production, as well
     as many other things.  However, it has been noticed that a tech
     center with 999 uws will produce tech less efficiently than one with
     500 uws.  The loss in efficiency is greater than what is expected
     from the tech limitation function, which is a non-linear function
     designed to limit fast tech production.  Most players do not feel that
     the loss in efficiency is worth it for the greater amount of tech

User's Guide to Empire                                  44

     production, especially in small countries where having two or even
     three tech centers is unrealistic due to the small amount of land
     available.

     As your technology increases, the possibility of there being an
     outbreak of plague in your country increases.  This is not of great
     concern until such time as your plague factor (found by the command
     "nation") increases above a factor of 3.0 or more.  Even if plague
     does break out in your country, if the plague factor is less than
     3.0 or so, the plague will have minimal effect on your country.
     During your first outbreaks of plague, you will lose some civilians
     but the birth rate of the civilians will be greater than the death
     rate.  Thus, increasing your research level (by opening and operating
     a research center, which requires the same materials as a tech center)
     prior to your plague factor reaching 3.0 is actually a waste of
     resources, time, money and effort.  This fact has been lost on a
     great many people and it is not uncommon to find many players
     boasting of a high research level long before you would have a
     plague factor of 3.0 without any research production.  While we
     have emphasised "3.0" as a point at which things start getting
     bad with plague, that is a vague figure.  Things start getting
     bad before that point, and get worse afterwards.  Its a matter of
     how much you want to put up with civilians dying off.

     There is a command called "report" which will list other countries,
     their status, and their levels of tech, research, and education
     relative to you.  If your tech is significantly higher than
     say a country called 'Canada' then report will indicate that
     Canada's technological level is 'backward' relative to you.
     If Canada's technological level is significantly higher, than
     report will indicate 'advanced', meaning Canada is advanced
     relative to you.  If its roughly the same, 'similar' will be
     shown.  There are two other possibilities, 'primitive' and
     'superior' which are used for extreme differences in levels.
     It should be noted that report is inaccurate at best, and only
     gives a very vague idea of levels.

Summary: Technology is one of the basic aspects of having a country that
      lasts to the end of the game.  Generally, the higher tech you are
      the greater chance of your survival.  However, if you have a high
      technology friend, you chances of survival are still increased
      greatly.  Empire is a classic case of cold war as far as
      technological development is concerned.  As a beginner, you are
      probably better off not producing a great deal of tech until you
      become well versed in how to run a strong economy.

     Special items:  Beaurocratic Time Units (BTUs), Available work (Avail)

                    Figure 13
            Table of types of commodities in Empire

--------------------------------------------------------------------------------

     Beaurocratic Time Units (BTUs) are used when executing a command, such
     as "build" for example.  They are also used to shuffle paperwork
     around, say for soldiers killed in combat.

     Available Work (Avail) is used up by producing sectors and those
     sectors in which you build things (planes, for example).  It is an
     indices of the amount of labor hours available for work.

     Running your economy efficiently as possible is one of the keys to
     being a good Empire player.  Without a good economy it is impossible
     to wage a long lasting war, especially an offensive one.  It is
     possible to last a long time defensively even with a weak economy
     but your chances are greatly increased if you have a strong economy.

     So, what defines an efficient and strong economy?  An efficient
     economy is one in which the amount of a product being produced in a
     sector is nearly equal to the amount that the civilians can produce in
     one turn.  For example, if a light construction materials (LCM) plant
     can produce two hundred LCMs an update, but is only producing one
     hundred, then fifty percent of the people in that plant are basically
     doing nothing.  They could be used elsewhere on something that needs
     more civilians or you could put more iron into the LCM plant to allow
     the civilians to make more LCMs.

User's Guide to Empire                                  46

     A strong economy is an economy that produces a lot of materials,
     resources, etc relative to the size of the country.  If your country
     has only say ten thousand civilians but is producing a large amount
     of materials per update then your country may in fact be a strong
     country.  This is a very unlikely scenario, but it is a good example.
     A strong economy is usually the result of an efficient economy,
     though there are other factors, those mainly referring to population
     growth.  To find out how much work your civilians are going to perform
     at an update you can issue the "prod" command to get a production
     simulation.  Using this you can see if all the civilians in a given
     sector will be making something or if some will be sitting around and
     doing nothing.  Here is a sample output from a prod command:

               Sample output of the 'prod' command

--------------------------------------------------------------------------------

     The important columns to note here are the "will" and "max" columns.
     If the number indicated in the "will" column is less than the "max"
     column by more than 1, then you have civilians who are sitting around
     doing nothing.  The way you calculate the number of civilians you have
     sitting around is fairly simple.  First, it is important to note that
     the number indicated in  the "wkfc" column is the number of civilians
     and uncompensated workers (UWs) you will have in the sector *after* the
     next update.  You need to reduce the number of civs and/or UWs in the
     sector to optimum *before* the next update.

     For this example, and for sake of ease, I am going to assume that
     there are no UWs or soldiers in this sector, which both produce work.
     We will assume that there are only civilians, and happy, content ones
     at that.  Civilians that are starved, or recently starved do not work
     as hard.

     In the above shown production simulation there are two sectors which
     have civilians sitting around idle.  These two sectors are the bank
     ('b') at -10,2, and the library ('l') at -8,4.  We will use the library
     for our example.

User's Guide to Empire                                  47

     The library is going to produce 40 education, but it is capable of
     producing 239.  It doesn't have enough lcms (the only material needed
     to produce education) to produce 239 education.  Thus, only the civs
     necessary to produce 40 education are actually working.  The remaining
     number of civilians, as a percentage, is calculated by this simple
     formula:

     ((# in max column) - (# in 'will' column)) / (# in max column)

     Thus, the percentage of civilians in the library not actually doing
     work is (239 - 40) / 239, or 83.26%.  That's a large percentage!  Now,
     to calculate how many civilians you can move out of the sector without
     reducing your production beneath 40 education in that sector, multiply
     .8326 * the number of civilians currently in that sector.  So, you need
     to do a census command:

--------------------------------------------------------------------------------

[162:166] Command : cen -8,4

                    Figure 15
          Results of a 'census' command of a library

--------------------------------------------------------------------------------

     There are 403 civilians listed in the 'civ' column for the library at
     sector -8,4.  Thus, you multiply 403 by .8326 and you find that you can
     safely remove 355 civilians from that sector and still be producing
     40 education.  That's 355 civilians that can be doing valuable work
     elsewhere instead of sitting around doing nothing!

     The other alternative to get the sector producing efficiently
     is to move lcms into the library up to the number that the library can
     possibly process with the current number of civilians.  Once again, we
     refer to the production report and note the 'use1' and 'max1' columns.
     The library will use 40l (40 lcms) at the next update unless you put
     more lcms into the library.  It can use up to 239 (239l in 'max1')
     lcms.  Thus, it can process an additional 199 lcms.  So, you find lcms
     somewhere else in your country and move the 199 lcms into the library.
     At the next update your library will produce 239 education.  Once
     again, all of the civilians in the sector are now doing something.

     Of course, you can also use a combination of these two methods to
     achieve an equitable balance.

     There are other aspects to running an efficient economy as well.
     Ideally, you do not want to have an abundance of raw materials lying
     around especially in the early stages of the game.  The best situation
     is to have your economy using the same amount of resources per update

User's Guide to Empire                                  48

     as it is making, thus having a zero delta situation with respect to
     all materials in your economy, you neither gain nor lose surplus of
     materials.  Keep in mind however that it is important to create and
     maintain a surplus of materials from which to draw on in times of war,
     especially later on in the game.  Without spare materials, you can not
     wage war very effectively.  In doing this you are getting the best
     balance of production, and are producing finished items at a faster
     pace then if you spent more work producing raw materials.  If you
     spent more work producing finished materials, you would run out of
     raw materials, and find that you have to move your civilians around
     to produce more raw materials or have them sitting idle doing nothing
     while your other civilians produce sufficient raw materials for them
     to do work.  The benefits of a balanced economy are obvious.

     There are additional tasks that are somewhat rewarding in running an
     efficient economy, but they become increasingly technical in nature
     and their impact as a whole against your economy is significantly less.

     As you become more experienced you will no doubt discover these thing
     yourself, or hear about them in a game or on the network.  These basic
     elements are more than enough for you to run smooth production if you
     adhere to them.

     There are still more elements of an economy which, while very useful,
     are not exactly related to the strength or efficiency with which your
     economy is running.  Your country, should it live for some time and
     develop a well balanced economy, will produce a huge amount of
     materials.  It is impossible for you to keep track of everything in
     each and every sector of your country.  Of course, the Empire creators
     realized this and have developed some critical commands for reducing
     by a very large amount the quantity of time you need to spend adjusting
     your economy.  These are the 'distribute' and 'deliver' commands.

     'Distribute' and 'deliver' are commands in Empire which allow
     you to set up your economy to run automatically, with little
     intervention from yourself.  Distribution is the most commonly used
     command in doing this.  However, deliver has certain features which
     are useful as well.

     Distribute is based on the central warehouse scheme of production
     and consumption of materials.  An iron mine produces iron, which it
     ships off to the central warehouse.  A light construction materials
     plant needs iron to make lcms, and thus requests iron to be sent to it
     from the warehouse.  The lcm factory produces lcms, and sends them
     off to the warehouse.  A library plant needs lcms to produce
     education, and requests lcms from the warehouse to do so.  The
     warehouse handles regional traffic for your economy.  Some smaller
     countries only have one warehouse.

     Deliver is based on the local delivery truck idea.  A nearby farm
     produces a certain amount of food per update, and sends it directly to
     the neighboring sector.  You know that the neighboring sector can
     consume more food per update than that farm can produce (this is very

User's Guide to Empire                                  49

     rarely true, this is just an example).  So, the farm sends all the
     food it produces to the neighboring sector.  The neighboring sector
     notes how much food has been delivered from the farm, and then requests
     from the warehouse enough food to feed the rest of the civilians in
     the sector.  In so doing things in this manner, you are possibly saving
     mobility by not having the food automatically move to the warehouse
     from the neighboring farm and then to the neighboring sector.  The same
     result would be achieved however, though as stated at a possible
     greater loss of mobility.  Nevertheless, most people prefer to depend
     entirely on 'distribute' to handle automatic distribution of materials
     around their country.

     To set up a distribution system, or network, you have to set a
     distribution 'path' *from* every sector *to* the warehouse.  I
     emphasize the direction that the path is moving in because all
     distribution paths go *to* the warehouse, not from the warehouse
     to the sector, though materials can and will go from the warehouse
     to the sector along that same path.  The idea here is say a farm
     outside of St. Louis about 50 miles produces 500 units of food, the
     farm needs to know the route by which it should send its trucks to get
     to a warehouse in St. Louis before it can send the food to that
     warehouse (this of course being a real life scenario). The best path
     to choose is across highways.  A 100% highway requires no mobility to
     move anything in to it.  Obviously you don't want to travel the 50
     miles to St. Louis across dirt roads.  You would prefer an interstate
     if you were a truck.  In Empire, a 100% highway is essentially an
     interstate.  Your goal is to have a distribution path from each sector
     to the warehouse travel the route over the least mobility cost path.
     The greater the percentage of that path that is 100% highways the
     better.  It is important to note that distribution paths have a maximum
     length of 10 sectors.  For example:

     Now there is a path along highways from the oil well to the warehouse.
     If you do not understand the nnnjujjjuj command above, refer to chapter
     3 and the section under "movement in Empire".

     Next, you need to set thresholds for the sector.  This sector is an
     oil well, and it produces, you guessed it, oil.  So, you want the oil
     that is produced to be shipped to the warehouse.  You have to tell the

User's Guide to Empire                                  51

     people in the oil well that all oil over 1 unit is to be shipped.
     This is called a "threshold", a level at which any quantity of that
     unit over that amount if shipped to the warehouse.  Note that the
     lowest threshold you can have and still have the item shipped is 1.
     If the threshold is 0, then it will not be shipped.  The command to set
     the threshold in the sector -15,1 for oil is:

[534:31] Command : threshold oil -15,1 1

     Next, you want to make sure that food gets out to the oil well.  The
     other aspect of thresholds is that if there is less than the threshold
     of a commodity, then the warehouse will send out enough of that
     commodity to equal the threshold, assuming it has such commodities in
     the warehouse.  The command to set the threshold for for in the sector
     so that food will go to the sector from the warehouse could be this:

[534:30] Command: threshold food -15,1 50

     Which means at each update, the warehouse will attempt to ensure
     that there is 50 food in the oil well at -15,1 by sending enough
     food, if it can, to raise the stockpile of food in that sector to
     50 units.

     Again, distribution paths must be set up for every sector that you
     intend on doing anything with.  Essentially, as the game progresses,
     this means all of your sectors.  You must also set appropriate
     thresholds as well.  Some sectors need iron from the warehouse to
     produce, and thus a threshold will be required for iron.  Some need
     more than one commodity, so thresholds must be set for each of those
     commodities.  EVERY sector should have a threshold value set for food.
     You do not want to starve your civilians!  To find out what
     commodities a sector needs to produce an item, use the 'production'
     command discussed earlier in this chapter.

     Some things to note about distribute:

1) No distribution path may be longer than 10 sectors.
2) A distribution path must go through sectors controlled by you.
3) Sometimes it may seem that the warehouse is not getting the commodities
   to the sectors requesting it.  Empire updates sectors one at a time, and
   as such the warehouse may actually run out of a commodity, receive the
   request for that commodity, be unable to fill it and move on the the
   sectors it updates after that sector.  Those sectors in turn may send
   commodities to the warehouse, thus giving it enough to fill the previous
   request.  However, since it has already updated that sector, it will not
   fulfill the backlogged request.  Empire updates the world left to right
   and top to bottom.  Thus in a map of your country the most north-west
   sector gets updated first and the most south-east sector gets updated last.
4) The warehouse has to spend mobility to send commodities to the requesting
   sectors.  Warehouses do this at a great reduction in the cost to the
   normal mobility.  However, if the warehouse runs out of mobility it
   will NOT distribute any more commodities for that update.
5) Do NOT set thresholds for all commodities in a sector.  Only set the

User's Guide to Empire                                  52

   thresholds for the commodities you KNOW that sector will need.  Distribute
   will not distribute commodities to sectors with the thresholds set for
   every commodity.

     Deliver is much more basic.  As a result however, it is much less
     powerful, though it is useful.  Deliver works as explained earlier in
     that it does local deliveries of a specified commodity.  Deliver is
     capable of delivering an item to only neighboring sectors.  During the
     update, deliver is done before distribute.  It is important to note
     that.  Let's say that a farm has a lot of food to send to the
     warehouse.  It may not have the mobility to send it all to the
     warehouse, and thus you get a large surplus left over in the farm.
     Eventually, the farm will not have room to store the surplus anymore.
     This is of course bad, since the farm will no longer produce very much
     food.  It will produce only enough food to replace what was taken from
     the storage at the farm.

     The solution to this is to have the farm sends its surplus to a
     neighboring 100% efficient highway.  This will cost the farm no
     mobility and will open up its storage areas for new production at the
     farm.  The highway can then spend mobility sending the food to the
     warehouse.  Once again, we use the map:

                    Figure 18
             Map of an area requiring delivery path

-------------------------------------------------------------------------------

     Let's say the farm at -5,-1 (just north of the middle) has a huge
     surplus of food.  You can send that surplus to the highway at -4,0 by
     issuing this command:

[566:115] Command : deliver food -5,-1 n (50)

User's Guide to Empire                                  53

     Which means, deliver all food in the sector at -5,-1 in excess of 50
     units in the 'n' direction.  Note the deliver threshold in parentheses
     must be in parentheses and that deliver thresholds are different than
     distribute thresholds.

     While I have described how to use the basics of deliver, I do not
     recommend it for the beginner.  Using a distribution network is quite
     sufficient for the beginning player, and you will not notice any great
     difficulty in running your economy without using the deliver command.
     In fact, some of the best players in Empire do not use deliver at all.

Summary: The things discussed in this chapter may seem time consuming, and
      may seem to require a lot of detail.  However, these things are
      important to you as an Empire player to learn and understand.  They
      become easy to use after only a short while.  Having a strong
      economy is the basic element in having a strong country.  If you
      have not understood this chapter, read it again.  Better yet, read
      it while experimenting with a couple of your own sectors in a game.
      While understanding 'deliver' is not very important, understanding
      'distribute' is.

Chapter 11 :-: War

     The art of waging war is certainly beyond the scope of this guide.
     There are a great number of books written on the history of man's wish
     to destroy themselves.  In this chapter, I only intend to give the
     player some rudimentary basics for waging Empire style wars.  Even more
     pertinent in the case of the beginner, how to defend against or
     hopefully repulse an invader.

     Keep in mind that as a beginner, you stand a very good chance of losing
     your first war.  Consider it a learning experience.  The person who
     defeated you is better than you are in most circumstances, and just by
     their actions you can learn how best to wage an offensive or defensive
     war.

     There are several things that you can do to defend your country
     in the event of an attack.  However, it is always best to be prepared
     for an attack before it happens.  There are some basics already
     discussed in this guide on these preparations.  Refer to chapter 8
     for information on automatic defenses, and how they can help your
     country.  I will review the essentials here.

     1) Have a strong airforce with many fighter planes with the intercept
        capability.  Make sure they are used as indicated in chapter 8.
     2) Have forts with overlapping fields of fire.
     3) Have a large number of reserves (typically 1/10 of your population).
     4) Have at least two enlistment centers ready to produce more fresh
        recruits.  Ie, at 100%.  You can "shut off" enlistment centers, that
        is stop them from producing recruits, by leaving 1 civ in them
        or having a military population in the sector equal to one half
        of the civilian population.  To turn them on, put in more civs or
        reduce the number of military.
     5) Have a strong navy to guard your coast.
     6) Mine your own coast.  This prevents many amphibious assaults.
        It also helps to prevent people from mapping your coastline.
     7) Have a good highway network.  This allows you to move materials
        and armies around your country quickly and with ease.
     8) Have more than one capital.  If your real one is taken, you will
        need a back up immediately.
     9) Have a lot of food in all of your sectors if possible.  This allows
        sectors that are cut off from your warehouse to be self sufficient
        at least with respects to feeding the people with food for a few
        updates until you can open up a path to them.

     These are just *basic* hints.  Some more hints are given later in this
     guide.  These are meant to get you started.

     Of course, it is better to not be attacked at all.  But, how do you
     avoid being attacked?  This is not simple, but there are some things
     that you can do to make yourself less of a target.

     One, do NOT allow people to map your coast using their ships,
     especially patrol boats.  Maps of your coastline are deadly.

User's Guide to Empire                                  55

     The opposing country knows where your country lies, and can furthermore
     send that information on to another player who might be interested
     in attacking you in exchange for some commodity or assistance.
     Maps are a critical piece of intelligence gathering.  Some of the
     best players in the game sink ships on sight without warning.  If you
     warn a ship off it might be able to use some of its mobility to
     make a final swing along your coast before going away, and seemingly
     out of your hair without having caused further trouble.  Every piece
     of information about your coast is valuable military intelligence.
     Additionally, it is a good idea to try to map other people.  Do not
     get upset when your ships get sunk.  They will get sunk.  Just consider
     them expendable commodities that are doing a temporary job with
     permanent results.

     Two, if you appear tough people generally will not attack you.
     Posturing can be an effective tool.  Furthermore, if you have a large
     airforce and/or army, people tend to avoid you.  It does not matter if
     your airforce only has wimpy planes in it, your opponent can only
     tell the quantity of planes that you have, not the quality.  They
     might have a general idea of the quality of your airforce, but a large
     airforce is still an intimidating presence.

     Three, do not make yourself a target by having a lot of valuable
     commodities showing up on your power report.  Having lots of money
     in a money poor game for example makes you a juicy target.  The same
     holds true with gold dust or oil.  You need not worry about iron and
     food, since those are renewable resources.  Try to use gold dust and
     oil as you make it.  Having some surplus around is fine, but the more
     you have sitting around the more of a target you become.

     If you are attacked, it is always best if you are logged on to the game
     so that you can actively defend your country rather than relying
     entirely on automatic defenses.  However, as can obviously be seen, you
     probably will not know that your enemy is going to attack you.  Neither
     will s/he broadcast that they are going to attack unless they are very
     foolish or extremely confident.

     In light of this, your opponent will try to attack you at a time when
     they know you are not logged on.  Thus, a great many Empire wars begin
     in the wee hours of the morning, when most people are asleep.  What can
     you do to overcome this shortcoming?  Have allies for one.  If one of
     your allies is going to be up most of the night you can have them
     telephone you if you are being attacked.  Of course, this is for the
     more diehard types :-)

     There are many tactics that an enemy will use against you.  Again,
     these tactics are beyond the scope of this guide, but there are some
     general tactics that you should be aware of.  An opponent may try one
     or more (usually more) of the following tactics:

     1) Remove your airforce as an effective retaliatory force.
     2) Remove your airforce as an effective defensive force.
     3) Take your capital (you lose half your money).

User's Guide to Empire                                  56

     4) Take your banks (you could lose all your gold bars, very valuable!).
     5) Destroy your highway system.
     6) Take your warehouses (lose your stored commodities. OUCH!).
     7) Bomb your enlistment centers.
     8) Take your radar stations.

     In addition, your opponent may try to destroy your distribution and/or
     delivery system (if you so opt to use deliver).  After you take a
     sector back from your enemy check the thresholds and distribution path
     in the sector.  Sometimes if you take a great deal of sectors back it
     is best to just use the 'wipe' command and start from scratch.
     Remember to check your delivery thresholds as well, by issuing a
     'level' command.  Your opponent will probably also redesignate the
     sector to something useless or even detrimental to you.

     It is important to be on around update times when you are at war,
     either defensively or offensively.  Things can go very quickly right
     before and after an update.

     One of the best ways of being a good military tactician is to be
     imaginative.  Think of ways to do things that might surprise your
     opponent.  Think of ways to do things that will cost you less lives,
     or less resources than your original way.

     There is a saying that sometimes the best defense is a good offense.
     This can be very true in Empire.  If you are attacked it might be a
     good idea to launch a counter attack against your opponent's homeland
     if you are able to.  This will certainly surprise them, and may lead
     them to think you are stronger than you actually are.  This can be a
     very powerful tool.

     If you want to win the war, be resilient and tenacious.  Fight as hard
     as you can with every last soldier and resource.  If you make your
     enemy pay a heavy price they may withdraw.  Sometimes breaking an
     opponent's will to fight is the most important factor in winning a
     tactical or strategic situation.  Even if they do not withdraw, or you
     do not win, you may at least be helping to defend the future of your
     allies.  That in itself is an honorable achievement.  There is also the
     point that if you are a tenacious fighter your opponent will respect
     you more in future games than if you just roll over and play dead while
     his/her armies pillage your country.  Reputation does count for a lot in
     Empire.  You may lose now, but your defiance in losing can help you a
     great deal in future games.  Some countries simply will not attack
     another country because they know that country's reputation as a good
     player.  Alternatively, some countries have a poor reputation and
     are attacked in every game they play in!

Summary: The art of Empire war is one that is different from the real life
      world that we live in.  However, many tactics from the real world
      can be applied to Empire.  Remember to be imaginative, learn from
      your mistakes.  Learn from your allies and your opponents.  Fight
      as if it was a real world nation, and you are the leader.

Chapter 12 :-: Other helpful or not so helpful hints:

     Here are some hints on how you might be better able to run
     your country.  Note that a lot of these hints were garnered through
     many player years of play.  You are free to disagree with them, and
     are certainly encouraged to come up with your own ideas.  However,
     keep in mind these recommendations.

     - Build your military reserves to a reasonably high level
       (I try to aim for 5-10% of my total population).  Reserves are
       not expensive to maintain, and it is a commodity that can not
       be destroyed by any military action.
     - As soon as someone starts building ships guard your coastal
       sectors with at least 1 military in each.  This prevents an
       opponent from making landings in mass quantity on your homeland
       with measly cargo ships.  If you have military in a coastal sector
       then opponent ships really need the "land" capability (see
       show ship capability command for further insight) in order to be
       truly effective.  Guard harbors with more military, say 50 or
       so.  Else an opponent can assault a harbor, move his or her invasion
       fleet in, unload the ships and walla several hundred foreign military
       are sitting in your former harbor.
     - As soon as planes start being built, try to get at least 10 military
       into every sector.  This makes it more difficult for a country to
       wipe you out quickly.  In this manner they usually need 2 or more
       transports to take a single sector.  This makes it costly in air
       mobility for them and softens the blow of their attack.  In addition
       reinforce capitals with a lot of military.  Same with banks, airbases,
       and warehouses.
     - Do not base your entire air defenses on non-VTOL (vertical take off
       and landing) planes.  Base your VTOL planes in non airport sectors.
       In doing this, you prevent your enemy from knocking out your airbases
       through any number of means and then flying at liberty over your
       country.  There are two VTOL fighters.  Fighter 1s, which are
       essentially biplanes with very brave souls in them and Jet Fighter 2s
       which are akin to the British Harrier jet.  Fighter 1s are not
       necessarily a bad plane.  Against low tech transports they do not
       fair too badly.  There are two other means of air defense if your
       airbases are knocked out.  Anti-aircraft guns exist in any sector
       that has guns and shells.  They will fire if the sector in question
       is at war with the planes in question.  They are mostly worthless.
       The other method is SAMs (surface to air missiles).  These can be
       quite effective but are shoot once only weapons.
     - Forts are an integral part of any home auto-defense scheme.  They
       will fire on any enemy aggressors that are within range whenever
       any sector of yours within range is attacked.
     - Naval units become essentially useless later on in the game except
       for some actions.  Nevertheless, be careful to have naval units in
       appropriate places around your coast for coastal defense.  Especially
       until you have planes that can pinpoint bomb well (jet lt bombers,
       jet f/bs, helicopters).
     - Always have several fake capitals in reserve.

User's Guide to Empire                                  58

     - If you are not using planes that are 100% and are not planes used
       in air defense, get them off your airports.  Otherwise they become
       easy targets for air assault and bombs.
     - Bridge span sectors are effective means of food production and
       are especially useful in that role in countries with few sectors
       or countries with limited fertility.  They are usually somewhat
       expensive to build, but pay for themselves quickly.
     - Keep in mind that allies are important.  You might want to go it
       alone, but at some point along the way you will need an ally or
       three.  Allies can do many things for you, not the least of which
       is call you over the phone when you are under attack at four in the
       morning.  Its nice to know that even though your country is not
       being played, someone is watching it from a distance and seeing
       whether it gets attacked or not.  You sleep easier :-)
     - If you are positive there is no one else on your island with you
       at the beginning of the game then demobilise your military and
       put them on reserve.  This will save you a lot of money, and help
       in population growth.
     - Never put airports, banks, or capitals on your coast.  They are
       easy targets for your enemies if you do.  Sometimes it is necessary
       to place an airport on your coast to get that extra one sector
       of range for your planes in an attack.  If you do that, don't leave
       your planes in that sector for very long.  You might be surprised.

Summary:  Many of these ideas can only be gained through experience.  Do not
       be come distraught for lack of knowledge.  Experience is a wonderful
       teacher.  These hints cover some of the major pitfalls of beginners,
       and that is all.  There are far more things to be learned that can
       only be taught through experience.

Chapter 13 :-: Some tricks and subtle tactics

     I have listed here some of the tricks used by the more advanced
     players in victimizing the beginning players.  I  divulge this hard won
     information because I feel it will make for a better Empire game for
     everyone.  In reading these, I hope that you will be encouraged to
     develop tactics of your own.  It is not hard to be imaginative.

     Note that not all tricks and subtle tactics will work as advertised.
     Some games have slightly different implementations that have a
     negative effect on these hints.

     - Sacking a warehouse.  This is an old tactic that is useful
       only in those games that have a market.  Essentially the trick is to
       take an opponent's warehouses or distribution points and sell off
       everything that is in the sector to the market.  You don't need a
       buyer immediately, just sell everything off.  If you want the items
       for yourself, sell them to the market at an exhorbinately high price
       and wait for a friend to buy them and sell them back.
     - Tracking an airbase.  This is a less known trick.  Non-VTOL planes
       intercept from airbases.  They also intercept from airbases in a hex
       pattern.  Ie, if the plane has a six sector intercept range it will
       intercept up to six sectors west, six sectors north-west, etc in all
       the six directions.  If you can find two corners of that plane's
       interception hex you can triangulate to find the sector from which it
       is intercepting.  This does work for VTOL planes as well, but isn't
       as useful since airbases usually have far more planes in them to be
       dealt with.  Once you have tracked the originating sector of the
       intercepting planes, what you do to that sector is your option.  Most
       often, a concerted effort will be made to crack the defensive fighter
       cover and blast the airbase.  Sometimes countries will use their
       surface to surface missiles (which do not get intercepted) to take
       out the airbase.  For non-VTOL planes taking out an airbase just
       means getting it below 60% efficiency.
     - Fort "walking".  If you have a land border with a country, you can
       use your forts to demolish a bordering sector with that country.
       By demolishing it, your are completely destroying every living
       civilian and soldier in that sector.  When that is accomplished you
       can explore into that sector as if it were wilderness.  You can then
       designate that sector into a 0% fort, which it will become
       immediately, and then move guns and shells into that sector.
       Then, you can do the same thing to a sector bordering your new
       sector.  In this manner you can slowly invade another country
       beyond a one sector advance in one update without the use of
       planes or ships.  This costs A LOT of BTUs and shells, but in
       critical situations is very useful.
     - Fire base.  This tactic has some relation to the tactic used in
       the Vietnam conflict by U.S. Forces.  The idea is to take an enemy
       sector in an area that you want to wreak havoc on.  Next, use your
       pinpoint bombing capable planes to bomb your own position's sector
       efficiency.  You will have some collateral damage on your troops,
       but it is well worth it.  When the efficiency drops below 5% you can
       then designate the sector into a 0% fort, place guns and shells

User's Guide to Empire                                  60

       in it using air transports, and then have a base from which to
       blast away at your enemy without the use of much airpower.  It is
       possible to use the fort walking tactic from this position.
     - Messing up a country's distribution paths and or thresholds.
       This is most often an "annoyance" tactic.  Most players know about it
       and check the distribution paths and thresholds of sectors they take
       back from an invading country.  The idea is to set the thresholds so
       that a lot of commodities will be distributed to the sector from the
       warehouse of your opponent after your opponent takes the sector
       back.  Then you can take the sector again and get the commodities
       if s/he has not noticed they are there.  Even if s/he notices it is
       a pain getting the commodities back to the warehouse.
       Alternatively, you can screw up the distribution path to run through
       a mountain and then to his warehouse, and also set the thresholds
       of the commodities quite high.  This will cause mobility in her/his
       warehouse to be used in great quantities to get the commodities to
       the recaptured sector.  Either of these ideas can get particularly
       nasty.  Say you conquer a sector, and set the thresholds on food to
       9000 units.  Your opponent takes back the sector, and neglects to
       reset the threshold.  At the next update the warehouse moves 9000
       food (or at least as much as it can) into the sector.  This might
       leave your warehouse without food to deliver to the rest of the
       country.  Food stocks begin to drop, with obvious repercussions.
     - Messing up a country's delivery routes and thresholds.
       Same as above except using deliver.  Many countries do not use
       deliver at all, and as a result are susceptible to this tactic.
       You can cause mass starvation in a country that you attacked, but
       no longer control without the leader ever knowing how.
     - Destroyer trap.  Move a submarine near a destroyer, say one sector
       away.  Lay some mines from the submarine, and then send out an active
       sonar ping using the "sonar" command.  Enemy destroyer rushes over to
       see what it is and KAWHOMP! hits a mine.  You can leave a sector that
       has mines in it safely but can not necessarily enter safely.  Every
       mine laid in a sector increases the chance of a ship hitting a mine
       while entering that sector by five percent.
     - Determining if someone is on.  You can get an idea of when someone
       is usually logged on by doing something like this:

[65:255] Command : news 10 | grep 

       This will scan the news file from the server for the last ten days
       (or however many days up to ten are being preserved in the news).
       You can then get an idea of when your opponent is logged on.
       There are tools that can do this for you, but so far none has
       reached public distribution.
     - Attacking any sector with one soldier repeatedly.  Within the code
       there is a small chance that against incredible odds a small
       collection of soldiers might win.  Taken to the extreme, there is
       a chance for one soldier to win, even against 400 soldiers, or so
       says the game.  Thus a player who wants a particular sector bad
       enough, may spend thirty minutes attacking a sector of yours
       over and over again with one military.  They might win eventually,
       and if it is important enough then they have gained a major sector.

User's Guide to Empire                                  61

     - A player might offer to sell you a type of commodity in several
       batches.  Or, you might just start buying batches of a commodity
       from any given commodity.  If the player you are buying from is on,
       they might change the price on you between batches that you are
       purchasing.  For example, DoDo starts buying food in batches of
       9000 from WabbleHead at 10 cents per food.  This costs DoDo $900
       per batch of food.  Suddenly between DoDo's 2nd and 3rd purchase
       of 9000 food, WabbleHead changes the price on the food from 10 cents
       to 10 dollars per unit.  DoDo never realizes it and pays $90,000
       for the 3rd batch of food.  Moral:  Don't purchase anything without
       checking the price first, and never buy in several batches at once.
       This applies to market and trade.
     - It is possible to move small quantities of a commodity across any
       sector in your country and not have it cost mobility.  To do this,
       you have to have the commodity moving from a warehouse to whatever
       sector you want to move it to.  The basic trick, is to move the
       commodity in batches of 5 or less.  Note this does not work for
       bars, and some other commodities.  It does work for food, shells,
       etc; items that do not take a great deal of mobility to move to
       begin with.  This trick is very effective for getting supplies
       to a region cut off from your main area without highway access
       and possibly even a mountain range separating you from it.
     - Mine your coast.  This prevents your opponents from effectively
       mapping your coast, and you can catch their ships in the act since
       a damaged ship moves a lot slower than a 100% ship.  Some people
       might even scuttle the ship in question to avoid detection.
     - Be aware that submarines will try to map your coast.  Use your
       submarines and destroyers to find them.  Use minefields as a
       preventative measure.
     - Do not give out your net address to anyone except the Deity unless
       people offsite can not finger you, or you have an account on
       another machine, and can regularly play from it.  People can finger
       you over the net to see if you are logged in or not.  If you're not,
       it's a good time to attack probably.
     - Beware of people offering you loans.  Make sure you know the terms
       of the loan.  Someone might offer you a loan that looks nice, say
       for $30,000.  But, the loan might expire in one day and have an
       interest rate of 127%.  The lending country can collect sectors
       directly from you without your permission if you are in arrears
       on the loan.
     - Defend your radar stations.  Always have at least 20 military in
       each of your radar stations, especially ones that are on the coast.
       Otherwise a passing ship might decide to capture it and take a
       snapshot of your country.
     - If a sub attacks one of your ships, it is possible to wander around
       the area with a ship that is not capable of sonar or depth charging,
       and still find that sub.  How?  Try boarding the sub by its hull
       number.  If a sub attacks you, you will get a message saying that
       sub number so and so did such and such to your ship.  Use a ship
       in the area to wander from sector to sector trying to board the
       sub.  If you find it, you will get a message saying that you can not
       board a sub.  Walla, you have found the sub without sonar, which
       other ships can hear anyways.  This is a nice quiet form of anti-

User's Guide to Empire                                  62

       submarine warfare.
     - You can load a missile cruiser full of anti-shipping missiles, and
       then create a script file with firing commands for every ship in
       existence.  Remove your own ships of course.  Then execute the
       script, and the missile cruiser will fire at only those ships
       that are in range, regardless of whether the ships are in radar
       range of the cruiser or not.  They need only be in range of the
       anti-shipping missiles.  This is an effective, if blundering, way
       of removing approaching fleets before you see them on your radars.
       Note: anti-shipping missiles are not available in standard BSD code,
       but are available in some other versions, namely the Kent State
       code.

Summary: Be sneaky.  Be imaginative.  Think of tricks you can pull on your
      opponent.  Quite often, they will in fact work.  Most players of this
      game are not Rommels, Pattons, or Montgomerys.  Many can be duped
      by very simple tricks.

Chapter 14 :-: Tools

     Tools are programs used by players on their local machines to
     assist them in developing their country, analyzing another country,
     conducting war on another country, etc.  Tools are very powerful
     devices at times.  As such, many players have tools that they consider
     to be military secrets and they do not release copies of them.  As a
     result, many programs doing basically identical tasks have been
     written.  I encourage those players that are reading this that have
     such secret tools to release them to an anonymous FTP site with a
     directory for Empire.  Not only does this make the game better for the
     beginners, but it also helps to keep the experts on their toes, and
     give a challenge to those of us who have been playing for quite some
     time.

     Some players feel that playing with tools takes something away from
     the playing aspect of the game, and feel that in so doing they are not
     really playing the game anymore.  This has lately turned into a
     religious war of sorts in the Empire community, with many people taking
     both sides of the coin.

     You do not need tools other than your client to play Empire.
     Empire is designed such that any player can play the game without
     hindrance without the use of a tool other than the basic client itself.

     What follows is a list of tools that are most commonly found
     among players of the game.  Most of these are publically available at
     an FTP site listed in Appendix C.

Tool      Purpose
autodist  Automatically sets distribution paths for an entire
          country or realm within the country.
autofeed  automatically feeds the people in your country.
pmvr,civmvr    Automatically redistributes your population so that sectors
          will be able to have population growth rather than maxing
          out at the limit of 999 civilians.
econ      Provides an analysis of your country's economic progress
          at the next update.
GEET      Gnu-Emacs Empire Tool.  An emacs interface for Empire that
          has a great many capabilities and functions.  Provides for
          better automatic defenses as well.
EIF       A more advanced client than the basic client.  Allows
          for aliasing commands, command editing, etc.
XEMP      Empire client for X windows.  Provides many nice features
          including an on screen map constantly displayed.  A very
          nice interface that unfortunately still has several bugs.

     These are just a few of the Empire tools out there.  There are still
     many more programs not listed.  Some cover news analyses, country
     analyses over several updates, etc.

     Most tools come with documentation on how to use them, and it is
     beyond the scope of this guide to illustrate how each one of them

User's Guide to Empire                                  64

     is used.

     There are other aids that are often called tools which are called
     scripts.  Scripts can do a great many things for you.  The most common
     of these applications are simply files containing a list of commands
     that you want to execute in Empire.

     For example, let's say that at each update you wanted to dump the
     current news into a file in your local directory, get a new power
     report and dump that into another file, and dump all current telegrams
     into yet another file.  This would be three commands that you could
     consolidate into one command by doing this:

     Construct a file in your local directory that has the appropriate
     commands in it.  In this case you could write a file with three lines:

news >>news.file
power new >>powerfile
read >>old.tele

     You could call this file update.do

     While in Empire you could then request the Empire client to access
     that file and execute those commands by using the exec command followed
     by the file name.  Thus:

[102:253] Command: exec update.do

     Building such a simple script is useful for doing a set of commands
     over and over again without typing it in each and every time.

     Lastly, remember to exercise wisdom in the use of tools.  It is
     possible that the execution of a simple tool can damage your country
     irrepairably.  Use tools, especially those written by others, with
     caution.  Try them out on small sections of your country first.  Look
     at the source code prior to running it if you have access to the
     source code.  It is theoretically possible for someone to write
     a tool that will scan the list of countries in a game, and if the
     author's country name is in that list, send valuable information
     about your country to him or her.  Yes, it is true, some people
     have no morals believe it or not.

Summary: Tools are very powerful items if used wisely.  It is not necessary
      to have tools to play Empire effectively.  Some experts of the game
      refuse to use tools of any type, and they remain among the best
      players.  Tools are no replacement for skill.  Be careful when using
      tools, they can ruin your country.

Appendix B :-: Known exploitable bugs

     As a result of Empire having several thousand lines of code, there
are numerous bugs.  Some are simply annoying, others you never notice.  Some,
like the following, are bugs that you can be used against you.

     a) "Intercept" bug - Non-VTOL planes can and will rise and intercept
        hostile planes from any sector as long as there is petrol in the
        sector, the plane has the intercept capability (see show plane c),
        it is at least 40% efficient, and it has mobility.

     b) "Escort" bug - Planes that are capable of escort duty can escort
        themselves on various missions, as long as they are capable of
        the mission in question (such as a bombing raid).  Say for example
        that you want to fly a reconnaissance mission over enemy territory,
        but you know that enemy planes are going to intercept you.
        When the game asks you for the plane that will be doing the recon,
        you can give it plane 345 for example, which for the sake of
        this guide is a jet fighter.  When it asks you for the planes
        that are going to escort it, you can say 345 again.  The game will
        respond as if two planes are flying the mission when in fact only
        one is.  Enemy planes will think there are two planes.  Enemy planes
        will first do battle with the escort.  Let's say they did 16% damage
        to the escort, and the escort did 14% damage to one of the enemy
        interceptors.  Next, the enemy interceptor attacks the recon plane,
        which is the same plane, and inflicts 21% damage.  The recon plane
        inflicts 13% damage on the interceptor, and the recon plane aborts
        the mission.  It looks like you lost the dogfight.  In actuality,
        you did not.  The intercepting plane suffered a total of 27% damage.
        It looks like you suffered 37% damage.  However, you actually only
        suffered the *last* damage inflicted, which was to the recon plane.
        Thus, you only suffered 21% damage and you won the dogfight.

     c) "Flying Bridge" bug - Say for example you have a 100% bridgehead
        sector with enough HCMs, workers, and avail to build a bridge.
        Normally, you would say "build bridge x,y" and then it would ask
        you for a direction to build the bridge.  If after you built the
        bridge you were to redesignate the bridgehead, the bridge would
        collapse.  However, if you redesignate the bridgehead sector
        before you build the bridge, the bridge will be built and will
        not collapse.  At the next update, the bridgehead will become
        the sector you redesignated it to (say, a highway) and the bridge
        will still be there.  Note: It is believed that most current
        games of Empire have a new patch that prevents this bug.

     d) "Resource sucker" bug - Let's say you have a sector with 23 gold
        content left, and it is a gold mine.  Normally it might produce
        say, 111 gold dust at the next update.  If you were to put 9000
        civilians into that sector, it would produce over 900 dust at
        the next update.  The sector's resource content of gold will go
        to 0, but instead of getting a roughly 115 dust from the sector
        with the remaining content, you have gotten over 900 dust.
        Civilians reproduce quickly enough that losing 8000 civs this way

User's Guide to Empire                                  68

        is really of no concern especially when you consider what you
        have gained.  This bug works also for oil wells and uranium
        mines.

     I have listed the bugs here because it is important that players
     know about these bugs in case they are used against them.  I do not
     condone the use of these bugs, nor do many players of the game.
     Many deities (the people who run the game) take action against
     players using these bugs, such as taking away your technology or
     your money.  Do not use them.  Simply be aware that others may use
     them and come up with ways to counter their use.  If you are aware
     that another player is using one of these bugs, report it to the
     deity of the game.  S/he might give you a reward of some sort.

     Also note that since these bugs have been published> here, it is likely
     that some programmer has written bug fixes for these.  Most, and
     possible all of these bugs might not work in a game you are
     participating in.

Appendix C :-: FTP sites and other sources for Empire related items

     Herein listed are the net address of computers that have files
     related to Empire in there anonymous FTP directories.  An example of

   Hints - Hints to help you play Empire better

Level: Expert

Military and the Demobilization of Same

   It's  generally  a good idea to put demobilized military on active reserve.
   You should also consider whether you need an enlistment center to  generate
   more  military.   You  can't  enlist  more  military than you have military
   reserves.  The nation command will tell you how many military you have.  Be
   careful,  as  many  players  have lost their countries through carelessness
   with their military at the start of the game.

   Actually, the enlist command cannot activate more military than you have on
   reserve.  Even then they have to be in sectors with an efficiency of 60% or
   greater.  Enlistment sectors can produce as many military as they are capa-
   ble  of, but will never produce more than one-half of the civilian populace
   there.  So you need to keep moving them out,  or  demobilizing  them,  etc.
   Also, the more military you have in an enlistment center, the more military
   get trained per update.

   Any civilian may be enlisted (no restriction on the efficiency of the  sec-
   tor).   No  more  may  be enlisted than the number of reserves.  Enlistment
   costs mobility whereas while demobilization costs cash.  Military can  only
   be  demobilized  in sectors with a 60% efficiency or greater.  No more than
   one-half the number of civilians in a sector may be enlisted in one  enlist
   command,  but if it is issued many times, virtually all civilians in a sec-
   tor may be enlisted.

   One thousand reserves is enough for now, although I  figure  I  always  put
   them on reserve when I demobilize, at least up to 10,000.

   So  you don't need to push for more reserves now, but might as well put all
   demobilized military on reserve.

   You make back the cost of demobilizing military in just two or three days I
   think, so I generally demobilize the military I don't have any use for, and
   put them on reserve.

   Depends on how you want to use them, I guess.  I figure with 200 jet trans-
   ports  at  127  mobility, I can land 20,000 military in an enemy country in
   one night, so I'd say 20,000 is a safe  upper  limit  for  reserves.   I've
   never needed more than that.

Distribution Hints

   When  distributing  stuff  to a warehouse, set the thresholds in the sector
   that is sending to or receiving from the warehouse to the amount  that  you
   want  left  in  that sector.  Don't set thresholds for the warehouse itself
   (unless its also distributing to another warehouse)

   The minimum threshold for distribution is one.  A threshold of 0  means  no
   distribution of that commodity will take place.

Something to Remember about Technology

   An  education  level  of five is required to build technology.  After "easy
   tech", the tech you build is put through a logorithm with "tech  log  base"
   (see version).

War Zones

   It  makes  it much easier if the player doesn't have to do anything to keep
   his country running, but can instead do the things that  are  of  interest.
   There's  also the problem of what to do in an invasion.  I guess if invaded
   I just accept the damage, and don't try to fix it until the war ends.

   In a war zone I generally follow one  of  two  basic  plans.   If  I'm  the
   invader,  I  either leave the sectors as they are and let the country being
   invaded fall apart, or if I can do something  to  make  it  worse  for  the
   enemy,  I  sometimes  do  that.  I sometimes designate conquered sectors to
   agribusinesses if they need food, banks to reduce shelling damage,  enlist-
   ment  centers  for military, forts for firing and attacking, harbors to get
   ships in, warehouses to collect, move, and  distribute  supplies,  airbases
   for planes and bridge heads for easy movement.

   When being invaded, I also generally postpone any long term development and
   just concentrate on the basic sectors types for combat (a,b,c,e,f,h,w,#,*)

   I've found it's a mistake to worry about long term  development  in  a  war
   zone,  until  the  battle  is  over.   I  will let a war zone be completely
   wrecked in order to achieve victory.  So you need to keep  your  home  area
   away from any war zones.

   So  far the method of treating war zones and peaceful zones differently and
   keeping them separated has worked pretty well.  The mistake I made  in  the
   past  was  to try to develop a war zone before the fight was over.  Now I'm
   willing to completely wreck the area to win, and in fact  you  pretty  much
   have  to.  The guerrillas take several days to get rid of even when the war
   is over.

   I mostly turn the sectors in the front lines into  forts,  enlistment  cen-
   ters,  banks,  and  bridgeheads.  Then maybe some warehouses, airports, and
   harbors within range of the front lines.  And maybe some radar stations.

Work Percentages are Important!

   I've found it good policy to produce a large surplus of  food  and  aim  to
   have  at  least 100 food in each sector, when I have enough. Actually I now
   put 990 food in each sector, except for aggies (100) and warehouses (9990).

   Before moving civilians, check the work in the sector the civilians are in.
   If it's less than 100%, DON'T move any of them out.  The  reason:  work  in
   the  destination sector will drop to the same level as the starting sector.

   It's a good idea to check after every update, to see if  any  sectors  have
   work less than 100%.  cen #0 ?work<100 is what I use.  If work is less than
   100%, workers won't work at full efficiency, and if it gets very  low,  the
   civilians  may revolt and you'll lose the sector.  Build lots of happiness,
   and keep extra mil in sectors with work less  than  100%.   That  seems  to
   help.

Definitions and a Good Thing to Remember

   World tech and world research refers to the technology and research made by
   other countries which will automatically leak to the less  developed  coun-
   tries.

   If  you let education get higher than happiness, then find work going to 0%
   in your sectors, don't say you weren't warned....

On Nuclear Devices

   Just a note on nukes: in this version, there  is  a  nice  balance  between
   nukes  and  economics.   A player can do a lot of damage with nukes, but it
   costs a LOT.  So it's rare that a country is completely  annihilated  by  a
   nuclear attack, as used to be the case in PSL Empire.

NAME
   Kill - How to kill your process on the server

Level: Basic

At some point you may lose your connection to the game.  When this happens its
possible that the game will not log your country off and you will get  a  mes-
sage  saying that you are still playing the game.  This can be easily fixed by
the player if you type in the following.

          telnet your.local.empire.machine 6666
          coun 
          pass 
          kill
          quit

What happens is that you are connecting directly to the Empire  Server.   From
there  you  enter  your  country name and password.  You can then kill the job
that's running and then quit so you can login again using the client.

This little trick will work on just about any Empire game.  Of course you need
to telnet to that game and and enter the correct country and password.

Its  a  good idea to write this down somewhere and DON'T LOSE it cause chances
are that you will have to use it at sometime.

Note that many clients offer a "kill" command which does this.

                                  A Preface
                                by Ken Stevens

       While most of this document applies to the game of Empire in its
current  form,  it is important to keep in mind that the sections which follow
this preface were written long before missions or land units  were  introduced
into  the  game.  The main impact that missions and land units have had on the
game is that they greatly strengthened the defense.  Here are "ten easy steps"
for setting up a strong defense in the new server:

   (1) Build 100% forts and put 10 guns and at least 100 shells in them.
   (2) Put at least 5 mil in all of your coastal sectors.
   (3) Build infantry units, put them in the forts, "fortify" them, and
       put them on "reserve" mission (info mission).
   (4) Build battleships and artillery and put them on "interdiction"
       mission.  Put the artillery in forts and fortify them.
   (5) Put infantry units in your banks and capitals, fortify them, and set their
       reaction radius to 0 (info lrange).

   ---later in the game---

   (6) Put lots of land mines in your ground (info lmine).
   (7) Build fighter planes.
   (8) Always guard your ships with destroyers (or other kinds of ASW ships).
   (9) Build some ASW planes and put them on interdiction mission.
   (10) Build lots of sam's and abm's.

A Treatise of Advice on War and Peace for Budding Empire Players by Dave Pare

This  article  contains  advice  for  beginning players.  It deals mainly with
staying alive and not economic development, because staying alive  is  tougher
for beginners than is playing with the various Sector-types.

The  most  important  thing  I  can say is that beginners should remember that
Empire is not realistic.  There are dozens of tricks to learn; until you  mas-
ter  them, you will lose because of small oversights Beware of patterning your
Empire actions after real-world strategies; they may not work as expected.

When you start, grab as much land as  possible.   Locate  and  identify  other
players,  and  get an idea of the size of your land mass.  Send them all tele-
grams.  Everybody likes to get telegrams; the telegram facility gives you  the
chance to make friends, influence people, and have fun role-playing your coun-
try.  If you get to know somebody, you may not be attacked  because  you  come
across  as  a  nice  guy.   Of  course,  if you sound like a bozo, you may get
stepped on.

Establish a definite border with your neighbors by inhabiting sectors with one
civilian.  This establishes your claim to the land behind these outposts, even
though you don't actually occupy it yet.  It also prevents your neighbor  from
discovering  where YOUR capital is.  In Empire, it's very important to protect
the location of your capital; likewise, it's quite nice to know  the  location
of the neighboring capitals just in case!

If any of your neighbors attacks your outposts, that gives you a valuable clue
to their intentions, while not costing you  much  in  the  way  of  resources.
Also,  an  attack on a remote outpost may give you enough time to prepare your
country for the possible invasion to follow.  You may not want  to  claim  too
much  land  though,  or the outposts will get overrun by people who are fed up
with your obvious land-grabbing.

Basically, try and be fair about land distribution, but make sure  you  get  a
good deal for yourself.

Empire players go to war for many reasons.  One is lack of resources; you have
land, and they want it.  Another is safety; your troops or ships are perceived
as  menacing, so they are destroyed by your adversary.  Another is because the
attacking player really enjoys attacking people!   Still  another  is  boredom
and/or curiosity -- Just how do nukes work anyway?  Hey, I know, I'll try them
out on Freedonia!

In Empire, wars are generally won by people who attack first.  Because  mobil-
ity  can  be  saved  up  your  attacks  can proceed while the hapless enemy is
asleep.  Many Empire attacks have happened over the weekend, or at 2:00 in the
morning.   It is quite difficult to defend your country when you're not logged
in.  The auto-defense features of the game are minimal at best.

The whole philosophy of First Strike holds true from early  land  warfare,  to
naval warfare, to the philosophy of Mutual Assured Destruction.  If you strike
first and your attack is well-planned, any retributive strike of  the  enemy's
will  be  ragged  at best.  If it's a land war, all of the fighting will be on
the enemy's territory, not on yours.  Your industries will be  fine,  and  the
battleground will be the enemy's.

Having mentioned the advantages of pre-emptive strikes, I must caution against
spur-of-the-moment attacks.  I've noticed that many wars tend to occur because
some  country  sinks  your  battleship; you get mad and decide to attack.  I'm
just as guilty of this as anyone.  Spending a few days marshaling your  forces
can  mean the difference between a long, drawn-out slugfest, and an overwhelm-
ing 2:00 blitzkrieg that blows away half the enemy's army and navy within  the
first  few hours.  While it's nice to have instant gratification (seeing enemy
troops die right after you read the telegram  describing  the  destruction  of
your  poor,  defenseless battleship feels SO good), a hasty counterattack will
alert your enemy who will mobilize forces and retaliate  accordingly.   Things
will  escalate,  and you'll be in a full-scale shooting war before you can say
Gulf of Tonkin Resolution!  And you will have lost the advantage.

Going first only counts if you have marshaled your forces.  A scattered,  ill-
planned attack will net you nothing but a little instant gratification, at the
cost of a long drawn-out war in which your neighbors who aren't  fighting  are
the  only  winners.   Once  two  countries are at war, it's much harder to win
overnight.  Vietnam is a good example of what you shouldn't do.  Gradual esca-
lation just gives the enemy time to prepare.  A sudden, overwhelming attack is
far better and will achieve your goals much more cheaply.

Knowing where the enemy is located is absolutely critical to the planning of a
successful attack.

War  takes  up  a  lot  of  resources; your personal time is the most precious
resource of all.  In a war, your time, energy, and creativity will be  devoted
towards  destroying  your  adversary.   This  leaves  little time for economic
development.  In war, the home front stagnates, or goes  to  seed.   Only  the
bare necessities are produced for the civilians at home, technological innova-
tion and new land development ceases, and your  country  will  generally  fall
behind in the global race for technology.

Therefore,  if  you  decide  to go to war, you'd better win quickly or else it
will take a lot of time, and your country will go downhill  fast.   If  you're
just punishing someone for doing something nasty, offer nice peace terms after
you've meted out appropriate punishment.   If  you  aren't  attacking  because
you're  bored, other players are likely to agree to peace because losing a war
is unpleasant.  I've turned enemies into allies often enough; they  are  happy
to  survive,  and  if  your attack was relatively justified, they are happy to
have you as a friend.

You'll notice I didn't give any advice to responding to an  attack.   I  think
being  attacked  is  generally  a  losing  proposition  because  in Empire the
attacker generally has the advantage unless fighting with greatly  lower  tech
equipment.

As  soon  as  ships  start appearing on the power chart, make sure each sector
bordering water has at least five to  ten  military.   When  more  ships  come
around,  beef  up  the  coastline defenses even more.  Put tons of military in
your capital.

To summarize, if you go to war, strike the first blow -- preferably at 0200.

Remember the cost in your own personal time investment.  Once the ball  starts
rolling,  you  won't  be  able to call it all off and go for a vacation.  Your
enemy will want to kill you, so you'd better be prepared to  spend  plenty  of
time in solid play.

                              Treatise of Advice
                                by Tom Tedrick

In  addition,  keep  mobility  in mind.  In many of my low-tech wars, superior
mobility was decisive.

Combining these ideas gives you my basic opening strategy: take as  many  sec-
tors as is possible, as quickly as possible (I will take 300 sectors the first
day if I can), and designate them highways, leaving one civilian in each  sec-
tor.  (You may need to leave one food in sectors with zero fertility.)

When  my  country first reaches 100% efficiency, roughly two-thirds of my sec-
tors will be 100% efficient highways.  This allows me to shift my  forces  all
the  way  from  one  border to another in a single move.  I once had great fun
smashing three countries that attacked me simultaneously from three  sides  by
shifting  all my forces from border to border to border, achieving local supe-
riority in each case, and annihilating the enemy forces  in  turn  at  updates
(this  is related to the theory of the advantages of interior lines worked out
by the Germans).

If the enemy runs out of mobility you can sometimes catch  the  main  invasion
force helplessly immobilized on the front lines and annihilate it.

Since  this is an advice note, I'll refrain from being too specific about tac-
tics.  You'll just have to learn them yourself.

Building the Perfect Beast: (Country Construction)

   The first thing you want is land.  Lots of land.  A whole hell of a lot  of
   land.  You should try to expand your country from the very beginning.  From
   there, you'll meet your neighbors who are doubtlessly doing the same  thing
   you're  doing.  Expanding wildly.  Now comes the first of a series of deci-
   sions you have to make.  Do you want to become a raging  power-mad  warmon-
   ger?   If  you  do,  be  sure  to have built your army beyond the basic 100
   troops.  The earlier in the game you find someone,  the  easier  it  is  to
   crush them into oblivion.  If you feel peaceful, see the diplomatic section
   of the text.

   Another difficult decision is designating your sectors.  A  good  beginning
   mix  is  two  mines  per light construction and heavy construction factory,
   about 20% agribusinesses (later dropping to 10%, 5%, or even none at all!),
   and  a  few  schools,  research,  parks, etc.  to fill up some of the other
   space.  The most important thing to have is a good transportation system in
   the  form of your highways.  Anywhere from 20-40% of your country should be
   highways.  You'll find them infinitely useful in moving food to a  starving
   sector,  taking  people  to  a  new settlement, or transporting troops to a
   local revolution, highways are vital!

   Another important consideration is do you want really want  to  win?   This
   implies the idea of competing in terms of building technology and research,
   and being able to get supplies to continue to produce both of  these  vital
   products  plus happiness, a high (greater than 10) education, maintaining a
   military force, etc.  Winning means succeeding on all fronts.   I  play  to
   win,  but find that I can't devote the time or effort to winning, so I usu-
   ally end up playing for the pure enjoyment of the game.  Ask Tom  [Tedrick]
   how many hours he puts into playing, and you can figure that is what you're
   going to have to do to win.  A final warning, if you play  seriously,  your
   grades  will  drop.   No  if's, and's, or but's about this.  You can't just
   throw three to five hours a day away and not have your schoolwork suffer.

Happiness is a Warm Gun: (The Art of Diplomacy)

   No one trusts anybody in this game unless you know them personally  outside
   of  the  limited scope of Empire.  Of course, this limits you a lot, so you
   break the rules and make alliances with people who you have no relation to.
   And they in turn backstab you and devastate the country you so meticulously
   built for the last few weeks.  Oh well, that's what you deserve...

   Just kidding.  Most of the people you will play with are rather trustworthy
   souls.   At  least  they  are  until it becomes burdensome to them.  A good
   relationship (as all those sex manuals will tell you) is based on trust and
   respect  for  the  other person.  What does this mean to you?  Build enough
   military to be a pain to invade.  Military power insures respect.  Trust is
   up to the two people involved.

Night Moves: (The Art of Empire)

   Empire is a skill.  Never forget that.  You will learn as you play that you
   may have to stay up for that 3:00 AM update  to  completely  surprise  your
   unknowing  victim  or even just to maximize your country's potential.  Also
   never forget that someone may be up at that time waiting to pounce all over
   you too.  Pleasant dreams.

Running on Empty: (Losing and still having fun)

   Okay,  you've tried to keep up with Tom [Tedrick], Chris [Guthrie], and all
   those other experienced people, but it just isn't going  to   happen.   You
   are  not  going  to win the big win (i.e., become world dictator).  What do
   you do?  Give up and watch your country go to pot?   Give  all  your  stuff
   away to another country and resign?

   No!  You can have fun even after you can't win.  Make small wars with other
   small countries.  Try to get a hold of nukes to  devastate  them.   Form  a
   cartel  with  other small nations and try to run over a big country.  As in
   real life, the possibilities are endless!  Look at the Middle East, they're
   having fun, right?

   This  is just a game, and from this point on, you don't have to worry about
   watching over your nation too closely.  Play for the enjoyment of  playing.

   Which, of course, is the intention of Empire in the first place.

                      On the Distribution of All Things
                              by David Bleckmann

The  reader  here is assumed to have read the information pages on distribute,
threshold, and level.

To use distribute, it is a good idea to have a warehouse.  You don't have  to,
but  this  is how the command usually works.  If for some odd reason you don't
use a warehouse, you will have to use some other sector  as  your  destination
sector,  as  mentioned in info level.  For novices, just build a warehouse.  I
will refer to warehouse instead of distribution sector for the  rest  of  this
text.

You should place your warehouse in a spot that can be reached by all your sec-
tors via a low mobility path.  That is, for each sector you own, there  should
be  a  path  along  which  you  could move goods at very little mobility cost.
Since 100% efficient highways don't cost any mobility to  move  across,  roads
that  come close to each of your sectors and lead to your warehouse are a good
idea.

Now for each of your sectors you must set up a  distribution  path.   Use  the
distribute  command.   This  is a path from each of your sectors to your ware-
house, along a low mobility path as described above.  For example, if you have
a nation that looks like this:

          j j m + c
            m + g * +
          h + w + k
           m + + g

And you wanted to set up a path from your capital, you would give the command
   [##:##] Command: dist 0,0 bbg

Note:  the  path can only be so long, and as your country gets larger you will
need more than one warehouse.

Once you have done this for all of your sectors, you are ready to  start  dis-
tributing.

Now you will probably want to have food on all your sectors, and if one sector
has a lot of people on it, you may want to have a bit more on  it.   You  will
not  want to have to monitor the food levels for all of your sectors.  This is
the process that is automated by distribute.

Using food as an example, you can go through all of your sectors and  issue  a
threshold command, such as:
   [##:##] Command: thresh f 0,0 40

This  will  set the threshold for food at your capital at 40.  You can do this
for all of your sectors using a command like
   [##:##] Command: thresh f #

And give a threshold for each of your sectors as prompted.

Now at each update, Empire will move food to and from  your  warehouse  in  an
attempt  to satisfy all your threshold requirements.  If for example a certain
sector has more than its allotted threshold of a  certain  product  (e.g.,  an
agribusiness  producing food), food will be moved off it to the warehouse.  If
a sector has less than its threshold, and the warehouse has any of  that  com-
modity, the product will be moved from the warehouse to the needy sector in an
attempt to satisfy its threshold.  If a certain sector has a  threshold  of  0
for a certain product, no distribution takes place.

Therefore  if  you  wished  to move as much iron as possible from an iron mine
every update, you would set its threshold for iron to one.  If somewhere  else
you  had a lcm factory that can use 45 iron a turn (found out through the prod
command) you would set its threshold for iron  to  45  (or  greater)  and  its
threshold  for lcm's to one.  Then, on each update, Empire would move all iron
off your iron mine (except for one unit), try to put 45 iron on your lcm  fac-
tory  and  take  all lcm's (except for one) off your lcm plant (possibly to be
used somewhere else).

Note: the order in which this happens is predictable, but  not  always  desir-
able.   Thus, if you have no iron on your warehouse to start with and your lcm
factory gets updated first, it won't get any iron even though  there  will  be
some in the warehouse in a few seconds.  It is always a good idea to keep sur-
plus goods in your warehouse.

The end result is that you can set up  your  country  to  move  your  products
around  without  you logging in.  It also doesn't cost as many mobility points
to move things as distribute, and it costs no BTU's!

                         Some Further Clarifications
                       on Distribution versus Delivery
                            by David Muir Sharnoff

   Secondly, I am still a little confused  about  distribution  and  delivery.
   When  I  designate a distribution route, does that mean that things will be
   delivered from the point of distribution to the warehouse?  Or  do  I  also
   have  add  the  delivery route on top of the distribution route in order to
   get things moving?  And how do I get the visual route of  the  distribution
   route?  I can get delivery routes by doing the route command.  Thanks.

The   two   methods  of  moving  commodities  (distribute/threshold/level  and
deliver/cutoff/route) are completely independent.

Delivery is most useful for short, one-sector, movement of commodities.   Dis-
tribute  can  be used in conjunction with highways and distribution sectors to
provide low-cost, long-range movement of commodities.  There is no  analog  to
the route command in the distribute paradigm.

Here are some examples of commands:

   [##:##] Command: distribute -2,0 jjjh
This  command sets up a distribution path from the distribution sector in -2,0
to sector 4,0.

   [##:##] Command: thresh food 4,0 400
This command sets the threshold on sector 4,0.  Sector -2,0 (the  distribution
sector  for 4,0) will attempt to keep 400 units of food in 4,0 by importing or
exporting as necessary.

   [##:##] Command: thresh oil 4,0 100
This command is the same as above, but will instead attempt to keep 100  units
of oil.

   [##:##] Command: level -2,0
This  command  will  report  the distribution routes and thresholds for sector
-2,0.

   [##:##] Command: deliver food -2,0 (384) y
This command will deliver all food from -2,0 in excess of 384 units to  -3,-1.

   [##:##] Command: deliver lcm -2,0 b
This command will deliver all lcm's from -2,0 to -3,1.

   [##:##] Command: deliver lcm -2,0 +30
This  command  will  deliver  lcm's in excess of 24 (deliver uses multiples of
eight).

   [##:##] Command: cutoff -2,0
This command will report what commodities are being delivered  from  -2,0  and
what their cutoffs are.

   [##:##] Command: route food -20:20,-10:10
This  command  will  graphically report the food delivery paths in the sectors
from -20:20 to -10:10.

                        Some More Hints for the Novice
                                 by Jeff Trim

Tech levels are very important in this game.  You cannot produce uranium, guns
or shells until you achieve a tech level of 40.

Choose  your  friends  carefully.  I was talking to Lewis from Cornell College
and his comment was the best I'd heard in a while:  Never  ally  with  someone
that  doesn't  have  a  definite  interest  in  seeing  you survive.  Don't be
deceived by the treaty command; treaty violations will show up  in  the  news,
but that is not going to stop the aggressor from wiping you out, no matter how
bad it looks in the news.

Nuclear attacks can cause a lot of damage, but no one has ever been taken  out
of  the  game by a nuclear attack.  The damage from a purely nuclear attack is
recoverable.  It takes conventional forces combined with nukes  to  really  do
damage.   (Of  course  I  won't fool you either; it doesn't hurt to have a few
nukes either.)

Beware of running low on BTU's.  I will recount one story of a player on  this
site that was running low on BTU's.  His enemies launched a nuclear attack and
hit his capital!  Unfortunately, he didn't have enough BTU's to redesignate  a
new capital.  The moral of the story is that you should plan an alternate cap-
ital at some point in the game.  These are generally not needed at the  begin-
ning  of  the game, because you need to effectively deploy your sectors in the
early going.  But later, it wouldn't hurt to have one or more alternate  capi-
tals.

Empire  is  a  game  of  perception.   If your adversaries think you're tough,
they're probably going to pass you and head for easier prey.  But the  reverse
is  also  true;  if  you  look weak they might try a few tactics on you -- and
depending upon your response, they'll either back down or fight it out.   Bar-
gain  from  a  position  of strength.  You could be the weakest country on the
planet but still look so tough that no one would bother you.  It's all percep-
tion.

Weak  countries have an added advantage: gun running!  If a country is heading
out with his fleet to attack another country and you happen to  be  along  the
way,  you  could  cut a deal with him and you could make a deal and allow that
country to attack a coastal sector and turn it  into  a  harbor.   You've  now
placed  an  obligation  on  that country, who will be very careful to keep you
happy so you won't grant similar privileges to  that  country's  enemy.   Weak
nations  can  be  quite powerful if you handle the diplomacy right.  The tough
players like blowing away their tough adversaries and as  long  as  you  stand
idly by and watch those two countries blow each other to little pieces, you'll
be left intact and growing richer off their little war.

NAME
   Overview - An Overview of the Game

Level: Basic

What is Empire?

   Empire  is  an  military/economic simulation of make-believe countries in a
   make-believe world.  The military part is emphasized.  The economic part is
   still there, but as a prerequisite to a working military.

What part do I play?

   Each player is the ruler of a country.  As leader of your country, you give
   commands that affect your country (e.g., move people  around,  re-designate
   sectors, etc).  You also handle all of your country's foreign policy.

   Empire  lets you get reports on the status of your country (``info census''
   and others), find out what's going on in other parts of the  world  (``info
   news''), and communicate with other countries (``info telegram'').

   Although  no  goal  is explicitly stated, most players rapidly derive their
   own, ranging from the mundane desire to be the biggest,  strongest  country
   in  the  game,  to the more refined goals of having the most efficient land
   use possible, or having the lowest ratio of  military  to  civilians  while
   still surviving.

The World of Empire

   Empire  is played on a hexagonal map partitioned into a rectangular grid of
   M x N sectors (where M and N are typically, but not necessarily, powers  of
   two,  usually  64, 128, or 256).  The world is made up of approximately 50%
   sea, 45% habitable land and 5% uninhabitable mountains.

   Sectors can be assigned a specific sector type.   These  types  range  from
   banks  to  nuclear  fuel  processing plants.  See ``info Sector-types'' for
   more detail.

   Your personal coordinate system is based on your capital, which is  a  type
   of sector.  Your capital is generally marked by the coordinates 0, 0.

The Empire Time Scale

   The Empire world both does and does not match the real-time world.  To bet-
   ter explain this, let us examine the concept of an update.

   At regular intervals (usually once per day), the  entire  Empire  world  is
   updated.   When the world updates, new population is added, ores are dug up
   and added to stockpiles, food and other commodities are distributed to sec-
   tors,  the educational and technological levels are updated, and so on.  It
   can be thought of as the minimum quantum for growth.

   On this time scale, an update could be considered to be  approximately  one
   generation.  Thus the difference from the time scale of the real world.

   However,  certain commands are issued in real-time, such as attacks.  These
   commands have instantaneous effects on the state of  your  country.   Dedi-
   cated  (or  merely experienced) Empire players will often log on to monitor
   their country.  And most attackers will wait until the small hours  of  the
   morning to carry out their attacks, for obvious reasons.

   If you do not log in to Empire, any automatic policies you have set up will
   be carried out.  However, Empire will not try to fix any mistakes you  have
   made; unless you are very careful, it's probably not a good idea to rely on
   these automatics.

Bureaucratic Time Units (BTU's)

   To prevent the more fanatical Empire players from staying logged on all the
   time,  Empire places a limit on the amount of time you may be logged in per
   day.  This limit is settable by the deity, usually 1000  minutes.   If  you
   run  out of time, too bad!  You can't log in again until the counter resets
   itself (usually at midnight).

   The other control on the number of commands that you may issue  are  called
   ``Bureaucratic  Time  Units''  or  BTU's.   A BTU is an arbitrary amount of
   bureaucratic bookkeeping that your government must spend to perform a  cer-
   tain function.  Most commands that are not merely informative cost BTU's.

   BTU's  are  generated  by  your country's capital.  The more efficient your
   capital, the more BTU's that are  generated.   The  number  of  BTU's  also
   depend on the game's settings.. See the output of the 'version' command for
   an estimate of BTU generation speeds.  However, you may have a  maximum  of
   512  BTU's  at  any  one time.  And once your BTU's reach zero, you may not
   issue any commands that use BTU's.

   Three things to note about BTU's:

    1)  Since commands use up BTU's, this limits the number of commands that a
        player  may  issue over a particular time period.  This has the effect
        of preventing the Empire fanatic from overruning  other  players  with
        less free time to log on.

    2)  The  build-up of BTU's is constant and does not depend on being logged
        in.  This allows players to participate when it is  convenient  rather
        than  at  some fixed time (such as most board games, or the stock mar-
        ket).

    3)  The BTU concept helps compensate for the fact that,  in  concept,  the
        governments of each country are always ``playing'' although the player
        representing that country may only log in periodically.

How long will a game take?

   Probably from one to four months.  You should expect to spend one  to  four
   hours  a day playing.  Also expect that if you do spend this amount of time
   playing, your grades or work will suffer.  You just can't spend  that  much
   time playing and either study or be productive.

What should I do now?

   When  a  new country enters the game, it starts out with an amount of money
   and two sectors.  These sectors are sanctuaries and have an initial  amount
   of  people  and  commodities.   Until  you break sanctuary, your country is
   effectively in stasis.  Nothing will change until you actually log  in  and
   force a change (such as designating a capital to begin accumulating BTU's).

   The absolutely minimal set of information pages you should read are: break,
   map,  ann,  wire,  tel, read, expl, move, res, cen, dist, thresh, lev, com,
   prod, budget, Sector-types.

A Comment from Peter S. Langston (the author of the original Empire game)

   It should be remembered that Empire is merely an  interesting  pastime;  in
   the vernacular, it's just a game.  There are many amusing stories of people
   that took the game too seriously; one tells of a corporate  Vice  President
   who  walked  into the computer room and flipped the main circuit breaker in
   order to stop an attack on his country; another tells of the  Harvard  stu-
   dent  that  refused to go to bed until everyone logged out of Empire and of
   the other players who took turns staying up late....

   While many players take Empire very seriously, an equal number  of  players
   use it as a safe environment in which they can act out their fantasies.  On
   occasion the fantasies involved are remarkably aggressive or  hostile.   It
   has  been my experience that the people with the most belligerent countries
   are often the people with the kindest hearts; anti-social game play doesn't
   necessarily  reflect  the  true  being underneath (or else I have some VERY
   weird friends).

A Brief History

   The game Empire is the most recent in a  series  of  territorial  conquest,
   political/economic  simulation  games initially inspired by a board game of
   the same name played at Reed College (Portland, Oregon).  Earlier  versions
   were  written  at Reed by Peter Langston and at The Evergreen State College
   (Olympia, Washington) by Chas Douglas, Peter  Langston,  Ben  Norton,  Mike
   Rainwater  and  others;  of particular note are the games Galaxy (Langston)
   and Civil (Norton).  The previous version was written in 1985 partly on the
   HRSTS Unix system at the Harvard Science Center, (Cambridge, Mass.), partly
   on the Unix system at Commercial  Union  Leasing  Corporation,  (New  York,
   N. Y.)   and partly on the Unix system at Davis Polk & Wardwell, (New York,
   N. Y.)  by Peter Langston with invaluable goading from Joe Stetson,  Robert
   Bradbury, Nat Howard, Brian Redman, Adam Buchsbaum, and a myriad of others.
   Since Langston never released source code for his version,  Dave  Pare  and
   friends  de-compiled  it  in  that  same year and have created this version
   which is very different.  Since then many re-writes and fixes have been put
   in and none of the original code exists anymore.  Many people have enhanced
   the code, most notably, Dave Pare added plane units in  1986,  Jeff  Bailey
   added  many  configurable  options  in the KSU distribution, Thomas Ruschak
   added land units and missions in  1992-1993  and  released  the  "Chainsaw"
   server,  and  Ken  Stevens  rewrote  much  of  the  server code in 1995 and
   released the "Empire2" server, and Steve McClure and the Wolfpack made lots
   of other changes and released the "Empire4" server in August of 1996.

NAME
   Suggestions - Suggestions for enhancements to the game

Level: Expert

     Whenever I think about new things for empire, I evaluate them in this
order:

          1) Is it fun?

     This is subjective, of course. The real question should be "Will the
majority of Empire players find this enjoyable?"

          2) Is is complicated?

     What sorts of new commands are needed? How will the player use the new
feature? Do new commands need to be added? How much will this change impact
the user?

          3) Is is code-able?

     How difficult is it to do? Does it involve minor changes, or a major
re-write? Many ideas have merit, but are prohibitively difficult to implement.

          4) Is it realistic?

     In general, realism is good, in that it makes the game more intuitive,
and easier for new players to learn.

             5) Is it play-balanced?

     It is important that the delicate balance between offense and
defense not be tipped one way or the other.  For example, a stacking
limit for land units would tip the balance too far in favour of the
defender.  Or, allowing more than one ship to assault at a time would
tip the balance in favour of the attacker.

          6) Is it important?

     If the change involves adding detail to the game, is the detail
important enough? Does the change go beyond the general level of Empire
abstraction? For example, a change to allow you to name each of your mil
would obviously be beyond Empire's general detail level. A command to name
ships is stretching it.

   Bugs - Known bugs in the Empire Server

Level: Expert

NOTE:  This  file is dramatically out of date.  The classification scheme used
by report is dumb.

You can make a sector temporarily useless by filling up all  its  fields  with
delivery and distribution information.  This is useful when an enemy is trying
to capture the sector (his mil don't have room to move in :-) You have to halt
some  of the deliveries or distributions to make room for the military to move
in.  (Mostly fixed by changing the number of available fields)

Warehouses can't distribute all commodities  simultaneously,  due  to  limited
fields for this information.  This becomes a problem if you have a countrywide
network of warehouses distributing to each other.  (Mostly fixed  by  changing
the number of available fields)

You  can  sometimes build planes in non-airport sectors, deliberately or acci-
dentally. FIXED

You can sometimes move small quantities of certain items from warehouses at no
mobility  cost,  even into mountains (this is my favorite bug, I'd hate to see
it fixed :-)

Guerrillas don't seem to carry the plague.

You can get information about enemy sectors  by  attacking  with  0  military.
This  costs 0 BTU's currently (this is another of my favorite bugs :-) This is
a good way to flood the enemy mailbox with junk mail  at  no  cost  in  BTU's.
FIXED

You  can  sometimes  trick someone into paying a huge price for commodities by
changing the price suddenly.  Therefore one should always  check  prices  when
buying commodities.

When  two countries are attacking each other simultaneously, you can sometimes
move into a sector he is in the process of attacking.  If you get  the  timing
right,  he  will  take the sector but you will get it back, along with all his
military.

If a plane is out to trade, and gets shot down, it can still be  bought  until
the  next  update.  If another country builds a new plane that gets the number
of the plane that was shot down, the new plane will go on the  trading  market
automatically.   Then  if  that plane is bought, the money goes to the country
whose plane was shot down, not the country that  built  the  plane.   I  stole
numerous  planes  (including  nuclear  missiles  :-) this way (by deliberately
putting low numbered planes up for trade, then having them shot down).

If a plane has negative mobility, then gets traded, mobility goes to 0.

Firing on sectors with land-locked sunken ships does strange things.

If two countries are cooperating, its possible to raid an  enemy  airport  and
steal the planes by putting them out to trade.

You  can also strip enemy sectors of commodities using sell, if you have mili-
tary control temporarily.

One can raid an enemy harbor and use up all the raw materials by building use-
less ships. FIXED

One  can make work go back to 100 everywhere in a country by moving all civil-
ians in low-work sectors onto a bridge, then collapsing the bridge.  Work then
goes  to 100 at the next update, if you leave some mil in the vacated sectors.
Or you can move mil out too, letting the sector ownership change to the Deity,
then  move  back  in  from a 100% working sector, and work goes immediately to
100.

Two cooperative countries can move commodities  around  at  no  mobility  cost
using the market.

You can depopulate an enemy sector in a raid by converting all civs to uws and
selling them.  This can make it hard for the victim to get back  in  the  game
even with a rapid & successful counterattack. FIXED, convert takes mob now.

Sometimes  sector  ownership  doesn't change when the last civ starves, so you
may get census information about sectors with 0 civs.  Later this same  sector
may get its ownership switched to the Deity without your doing anything. FIXED

You can only have so much of a commodity in a sector.  If you went over 32,000
and  something,  units  of  food, for example, bizarre things might happen.  I
think that has been fixed. FIXED

Treaty had bugs (for example, firing on any ships was considered a treaty vio-
lation,  not  just  the  ships of the country you had a treaty with).  I think
Jeff might have fixed this. FIXED

Also air attacks were not considered treaty violations.  This  may  have  been
fixed. FIXED

You  can  collapse enemy bridges by making a lightning raid on his bridgeheads
and redesignating them, even if you only hold the bridgehead for a short time.
(In this games, bridges work differently, see info build, info bridges")

You can map out enemy territory by raiding his radar stations.

Condition  checking  is very treacherous.  Global commands with conditions are
unreliable.  I never figured out exactly what was wrong, although I think your
method of putting conditions towards the front of the line helped sometimes.

You  can  have  more than 26 ships in a fleet, but only the first 26 will move
when you navigate the fleet (I think 26 is the right number, but I'm not  cer-
tain.  It might be 32).

Look  only spots subs (from destroyers) at a certain distance.  If you are too
close you won't see them (unless you are in the same sector).

You can only fly as many planes on a mission as you can  fit  on  the  command
line (so low numbered planes have an advantage this way).  USE WINGS

I  never  managed  to load more than 1 warhead on a missile, but I didn't have
time to investigate this thoroughly. FIXED

Wilderness sectors that you own don't appear as ? on enemy maps,  so  you  can
sometimes hide information by leaving sectors as wilderness. FIXED

When  a  sector  has  a visible ship, radar doesn't show whether the sector is
land or sea, just the ship.  This has interesting possibilities for  exploita-
tion  (like  land-locking a battleship in your capital in order to deceive the
enemy :-)

I don't think you can land planes on a land-locked aircraft carrier anymore.

Its common to mistakenly set the price of a plane or ship incorrectly  so  one
should check trade after using set.

Torpedo  isn't  random,  but always works within range (another of my favorite
bugs :-) FIXED

Transporting nukes costs 0 mobility. FIXED

The must be accepted by date on offered loans is bogus.

Turn off doesn't stop updates.

NAME
   CHANGES.CHAINSAW - Changes from KSU Empire to Chainsaw code

Level: Expert

CHANGES.CHAINSAW.1.0

Changes to the Chainsaw code in version 1.0

This file enumerates some of the more important changes between BBN Empire 1.0
& BSD Empire 1.1.5, KSU, & MERC empire. BBN Empire 1.0 is a  superset  of  the
other  versions,  including  all MERC code, which includes all KSU code, which
include the BSD 1.1.5 code.

Bug-fixes

Scrap and scuttle will now ask for confirmation before scrapping or  scuttling
wing  or fleets. The will also ask before scrapping or scuttling ALL planes or
ships (when a '*' is given as an argument)

Bomb has been changed to allow planes with the P_T (tactical bomber)  flag  to
bomb,  even  if  they  are also cargo planes. This fixes the problem with Zep-
pelins not being allowed to bomb.

Power has been modified to not report on all deity countries  (as  opposed  to
just ignoring country 0)

The  plane  functions  have been extensively modified to calculate and enforce
the ship plane-capacity limits. In previous versions, this was  enforced  only
in  the  load  command, and incorrectly maintained. (In some situations, the #
could go negative, and wrap around to 255, causing much disbelief)

The telegram command was changed so that bulletins from a  deity  include  the
name of the deity country that sent them. (Useful for multiple deity games)

The  nation files are re-read for the report and country commands. Before, the
program would use the in-memory nation stuff, which meant that it was  out  of
date if it changed (i.e. people logging in/out after you would not be shown as
logged in in the country output, report would be out of date, esp in  blitzes,
etc)  With this option, the nation file is closed and re-opened, which updates
the in-memory stuff to be current. This is still not perfect, as  when  people
exit  incorrectly,  they  are  still shown as logged on, until they telnet and
kill the process, or the transaction manager is restarted.

Also, the init_nats function was changed. Previously, if  a  country  did  not
receive a BTU delta when logging in, its last login time was not set.

OPTIONS

Many new options have been defined for BBN 1.0.

CHOPPER-STEALTH

Choppers  have  a chance of evading interception. It isn't as good as stealth,
which is why it's listed as half-stealth. I'm not telling the exact numbers...
figure them out for yourself.

BABY_NUKES

Credit  for  this  idea  goes to Tom Tedrick. Damage/effects are the same, but
blast effects are confined to the target hex. This also automatically turns of
MISSING MISSILES. Note that launch will still ask about air/ground burst.

SUPER_BARS

Gold  bars  cannot  be pin bombed, and are not hurt by firing. There are still
ways to kill them, but not by shelling or bombing.

EASY_BRIDGES

A bridge can be built in any sector adjacent to one of yours,  providing  that
the  target  sector is adjacent to a non-sea, non-bridge sector. Since bridge-
heads are not required, you can't collapse bridges by killing the head.   (You
can  still kill them by taking the bridge below 20%) This also fixes a problem
with planes on bridges not dying when the bridge dies. (This was partly  fixed
before, but the fix didn't work all the time)

Note that the sector building the bridge may be a bridge, providing the sector
that the bridge is being built in is adjacent to a non-sea, non-bridge sector.
For example, this is legal:

 . . . . . . . =>    . . . . . . .
 . - = . - . . =>    . - = = - . .
 . . . . . . . =>    . . . . . . .

This is not legal:
 . . . . . . . =>    . . . . . . .
 . - = . . - . =>    . - = = . - .
 . . . . . . . =>    . . . . . . .

Also, the sector building the bridge must be at least 60% efficient.

BETTERARMOR

Ship's  armor  factors now more greatly affect both shelling and bombing. BB's
are much harder to kill. Smaller ships are more fragile..s1
ALL_BLEED

When this option is enabled, countries receive tech leakage from ALL tech pro-
ducers,  not merely allies. Tech leakage is 33% by default. The leak is calcu-
lated as 33% of the average tech made by all those making tech.  For  example,
if  there  are 10 players, making 3, 4, 0, 0, 3, 0, 2, 0, 2, 1 tech, the total
tech made is 15 by 6 countries, for an average of 2.5 tech. All  10  countries
would  get  .833  tech leak (33% of 2.5), for total tech production of: 3.833,
4.833, 0.833, 0.833, 3.833, 0.833, 2.833, 0.833, 2.833, 1.833

DRNUKE

You need research to build nukes. (1/4 the tech value,  so  a  tech  300  nuke
needs 100 research)

SLOW_WAR

You  cannot  attack  someone's  land unless you are at war with them. (You can
still blow up their ships with fire, board, torp, etc) When you declare war on
someone,  your relation goes to Mobilizing. You still can't attack them. After
the next update, your relation goes to Sitzkrieg, and you still  can't  attack
them. After the NEXT update, you're at war with them, and anything goes.

If  someone is Mobilizing or in Sitzkrieg, or At War with you, and you declare
war against them, your relation is set to be the same as theirs, so  there  is
no  way to gain any advantage through this stuff. It just means that you can't
sneak-attack people.

The restrictions do not apply if you are the old_owner of the sector.  If  you
are the old_owner, you may bomb/shell/attack at will.

Note that while ships are freely attackable, regardless of war status, even if
they are in a harbor of a nation you are not at war with.

The first person who declares war pays $1000. Return declarations are free.

NOMOBCOST

Ships do not use mobility when firing. Torpedo mobility cost is reduced to  be
equal to 1/2 the mobility the firing ship would use to move a sector.

NEWSUBS

This option encompasses several small changes in sub-warfare. A new flag, sub-
t, is added. Only ships with the sub-t flag are allowed to torpedo subs. Also,
ships  with  depth-charge capability can now use them to their full gun range.
Depth charges are  more  affected  by  sub  armor  value.  Torpedo  damage  is
increased.

OTHER-CHANGES

Most of the ships have had their firing ranges bumped up significantly.

CHANGES.CHAINSAW.2.0

Changes to the Chainsaw code in version 2.0

This  file enumerates some of the more important changes between the code used
for BBNII (Chainsaw Empire 1.0) & Chainsaw 2.0.

Bug-fixes

You can no longer map by attempting to land planes on  unknown  sectors.   The
replies have been standardized to give no information.

The radar command is fixed to eliminate 'ghost' images at high tech.

Planes can now land on carriers that happen to be in bridge sectors.

You  can no longer find out if any enemy subs are under your bridges by trying
to load things on them.

You can no longer load things onto non-allied ships, even if  they  are  in  a
harbor you own.

to 0,0.

When  specifying  a flight path, the terminating 'h' is no longer counted as a
sector for purposes of range.

Qorder is now documented, and works as described in the document.

CHANGES

When scrapping or scuttling groups of ships/planes or wings  of  ships/planes,
you will be asked to confirm that you want to do it.  (Also when doing scrap *
or scuttle *)

Ships that assault will always retain 1 food.

You may now specify a "number to build" parameter for build.

The deity can now make declaration on another country's behalf.

Minesweepers now take less damage from mines (1/2 the normal amount).

A plane unloaded in an ally's harbor now becomes his  plane.  A  plane  loaded
onto an ally's ship also becomes his plane.

Your  planes  may  now  land  on  an ally's sectors or ships. Once there, they
become his planes.

Ships will fire back in defense  of  sectors  being  attacked,  assaulted,  or
shelled.

Your  ships/sects  will no longer shoot themselves in defense.  You can cheer-
fully blast your own ships/sects without fear of  retaliation  from  your  own
forces.  You  can  also torp your own ships, and they will resignedly watch as
the torps slam into them.

Gun ranges are no longer truncated. Instead, there is a % chance equal to  the
decimal  portion  of  the range of gaining a hex. For example, with a range of
2.50, there is a 50% chance of being able to fire at range 3. With a range  of
6.33, there is a 33% chance of being able to fire at range 7.

The  power report has been changed to be more realistic. The relative worth of
most commodities has been changed, and a country's total is  multiplied  by  a
tech factor to arrive at a final value.

There  is no longer a minimum maintenance cost of $1/ETU for planes and ships.
The new minimum is $1.

The torpedo command is changed. Surface ships may now have the  torpedo  abil-
ity, as well as subs. When surface ships torpedo, they are fired at by defend-
ing ships BEFORE they fire their torpedos.

An "escort" flag was added for planes. Planes with the escort flag may  escort
missions. (Formerly, only planes with the intercept flag could escort)

Fighter  aircraft  being used as tactical bombers are now at a greater penalty
in air-to-air combat.

Ships with no mobility may now be nav'd. This allows  fishing  boats  and  oil
derricks  to  check  resource values without having mob. (Of course, you can't
move with no mob, and an attempt to do so kicks you out)

The load command will now allow you to load wings/groups of planes.

You may now give things to allied ships using the tend command. (You  may  not
take things from allied ships, only give) (If ALLYHARBOR is used)

You may now upgrade allied ships. (If ALLYHARBOR is used)

Your civs will work on allied ships in your harbors. (If ALLYHARBOR is used)

You  may assault your own sectors. Mil assaulting are simply added to the num-
ber in the sector.

You may now land planes on a carrier in an allied harbor.  (If  ALLYHARBOR  is
used)

Conventional non-tactical missiles will now be intercepted by ABM's.

Options

Trade-Ships

Trade  ships  simulate internal or external trade. In the real world, you make
goods someplace where they're cheap, ship them  somewhere  they're  expensive,
and sell them, making a profit.

For  empire  purposes,  you make a trade ship, which uses many cm's, and costs
$2500. You then sail it somewhere and scuttle it. You  get  money  back,  more
than  you  put into building the ship. The return rate depends on several fac-
tors.

The primary factor is distance. The distance is  calculated  as  straight-line
distance from the sector the ship is scuttled in to the sector in which it was
built. You have to sail it at least 8 sectors to get any profit at all. If you
sail it more than eight, the profit rises steadily.
          dist < 14:     +3.5% * dist
          dist < 25:     +5.5% * dist
          otherwise:     +7.5% * dist

Another  factor  is the sector in which you scuttle it. If you scuttle it in a
harbor you own, you get normal cash. If you scuttle it in  the  harbor  of  an
ally,  you  get  a 20% bonus, AND your ally gets 10% of the cash you make as a
bonus (you still get the full amount)

For example, using the numbers from above, if you sailed 15 sectors, and scut-
tled  in  an allied harbor, you'd get $4562 * 1.2 = $5.5K, and your ally would
get $4562/10 = $456.

The last factor is the efficiency of the trade ship. The cash return is multi-
plied by the efficiency of the ship when it is scuttled.

Note that captured trade ships can be scuttled by pirates, who receive cash as
if it was their own.

FUEL

Each ship has a fuel capacity, and a fuel usage rate. During an update,  ships
use  fuel at a rate of 10 mob for every  units of fuel. Ships with
a fuel usage of 1 get 10 mob for every 1 fuel, ships with 2 fuel usage get  10
mob for 2 fuel, etc. Ships with no fuel do not get mobility. Ships with a fuel
usage of 0 do not need fuel. (Sailing ships & nuc ships/subs)

A new command, "fuel" is added. It allows fueling from a harbor sector,  or  a
ship  or  ships  with the "oiler" flag. When fueling, petrol and/or oil in the
harbor or on the oiler is exchanged for fuel points, which are loaded  on  the
ship.  Petrol  is  used  first, if available, at a rate of 1 pet = 10 fuel. If
there is not enough petrol, oil is used, at a rate of 1 oil = 50 fuel.

Ships of allies can be fueled, if the ALLYHARBOR option is in use, either at a
harbor, or with an oiler.

SEMILAND

This  option  adds  a flag, "semi-lander", which allows the ship to use 25% of
its mil in an assault.

SHIPCHOPPERS
XLIGHT

These two flags are similar. They establish  new  plane  flags,  "helo"  (ship
helicopter),  and  "x-light"  (extra  light).  Each ship is then rated on it's
ability to carry those types, independently of it's ability  to  carry  normal
planes. This allows deities to let non-carriers carry sams, for example, or to
let ships carry anti-sub helicopters or transport helos.

ASW_PLANES

A new plane flag is added "asw". This allows planes with the flag to spot subs
on  recon missions. (Detection chance is (100-accuracy)-(4-sub visibility)*10)
Planes with this flag may be informed (depending on  detection  ability)  when
pin-bombing a sea-sector of the presence of subs. They then have the option of
bombing the subs. Each plane on such a mission rolls separately  to  find  the
subs, and can only bomb the ones it can find.

PARAFLAG

A  "para" flag is added for planes. Only planes with the para flag can be used
to paratroop.

STEALTHV

This option adds a new statistic for planes, stealth percentage. Use  of  this
option  effectively disables stealth planes and the CHOPPER_STEALTH option, as
the stealth and half-stealth flags are ignored.

With this option, each plane is rated as to its  percentage  chance  to  evade
ground-fire and interception. The stealth rating of a group of planes is equal
to the rating of the plane in the group with the lowest stealth rating.

MULTIFIRE

When this option is used, both fire and torpedo accept multiple ships/sectors.
Each firing ship/sector may be used against a separate target, or all may fire
together.

Return fire is distributed evenly over the  firing  ships/sectors,  with  each
defending  ship/sector  firing  once.  The spreading of damage also applies to
subs being depth-charged after torping, and for torpedo boats being  fired  at
prior to torping.

RETREATS

Each  ship/fleet  may  be given a retreat path, and retreat conditions. Condi-
tions are: retreat when damaged at all,  retreat  when  torped,  retreat  when
sonared,  retreat  when  fired  upon from beyond max range, retreat if bombed,
retreat if depth-charged.

Retreat conditions are assigned to ships, and may be assigned to entire fleets
at once. When a ship's retreat condition is satisfied, things happen.

If the ship's fleet has a retreat path, all ships in the fleet that are in the
affected sector attempt to retreat 2 sectors along the path, using mobility as
if they were navigating.

If  the ship's fleet does not have a retreat path, then the ship checks to see
if it has it's own retreat path. If so, it retreats 2  sectors  along  it,  as
above.

Note that retreating ships can hit mines, and could be blocked by new bridges,
or by an ally changing to non-allied status (which would make them  unable  to
retreat into a harbor)

Retreat  paths  are  wiped  from a ship when the ship moves. Retreat paths are
wiped from fleets only at the player's request.

HARBOR_POLICE

With this option, the board command is extended to  allow  boarding  of  enemy
ships  in  your harbors. The harbor sector must have mobility, but the command
does not use any mobility.

MINE_PLANES

With this option, planes with the mine ability are allowed  to  use  the  drop
command to drop shells as mines in sea sectors. (see info drop)

SWEEP_PLANES

With  this option, planes with the sweep ability will automatically attempt to
sweep mines while on recon missions. See info recon for more details.

BUDGET  This option changes the update ordering a bit, and allows you  to  set
priorities  for  production, for those situations where money is tight.  A new
command, budget, is added, that shows financial information, and  allows  set-
ting of priorities.

DAVYJONES

When this option is used, nukes striking wasteland or sanctuary sectors do not
detonate. Nukes striking water sectors affect only their impact sector.

Thanks go to all the people who've helped me with ideas and playtesting: Jorge
Diaz  (Ansalon),  Tom  Tedrick (Afrika Korps), Keith Graham (DreamLands), Dave
Nye (Evil_Empire), Sasha Mikheev  (Dolgopa),  Baldric,  Elsinore,  Brett  Reid
(Resvon), Kazzadur ystein Tvedten (Flipper's evil twin), Tharkadia, Yikes, and
many more I'm forgetting. The good things  are  mostly  ideas  contributed  by
these people. The bugs, I'm afraid, are my own.

                         Thomas Ruschak (The_Scum)

CHANGES.CHAINSAW.2.1

Changes to the Chainsaw code in version 2.1

Chainsaw 2.1 has some minor differences from Chainsaw 2.0.

Now,  when  navigating,  sonar  or  radar commands will default to the current
ship, or the first (lowest numbered) ship in a group. You may override this by
specifying the desired ship on the command line.  (I.e. "r 12" or "radar 212",
etc)

The chance of a plane aborting is changed to (100-eff)%. This means that if  a
100%  plane  takes  a hit for 30% damage, it has a 30% chance to abort.  If it
then takes another hit for 20% more, a total of  50%  damage,  it  has  a  50%
chance  to  abort.   Also, when bombing ships, rolls are not made for aborting
until after all ships have fired, rather than rolling  every  time  the  plane
takes a flak hit from a ship.

A  new  command  has  been added, the 'payoff' command.  It shows the value of
trade ships if scuttled at the current sect (check info payoff).

Constants have been added to control ship & plane efficiency growth  rate.  It
is now possible to allow 2xETUS growth in efficiency, 3x, etc.

Subs may no longer shell.. they may only torpedo.

A WIRE option has been added that activates the announcements. The normal read
command then reads only telegrams & bulletins.

When assaulting, troops will always leave at least 1 food on the ship.

You may now build multiples of an item by adding a build count at the  end  of
your build command. (see info build)

You may now give comments in the hours file. Comment lines start with a

The  report  command  has  been  changed to not include countries that are not
active. (i.e. visitor or in sanctuary)

The version command now show the ship/sector/plane mobility max/gain, as  well
as the ship/plane growth constants.

CHANGES.CHAINSAW.2.2

Changes to the Chainsaw code in version 2.2

Chainsaw 2.2 has some minor differences from Chainsaw 2.1.

A  new  option,  SNEAK_ATTACK  is included. It can only be used in conjunction
with SLOW_WAR. It allows you to attack a sector of someone you're not  at  war
with.  Once  attacked,  the  attacker  automatically  declares war against the
defender, and pays $5K.  At that point, the attacker has  to  go  through  the
normal  SLOW_WAR  procedure  before  attacking  again.  See  info attack, info
assault.  SNEAK_ATTACKs may not be done by parachute.

The 'list of commands' command now puts  a  'c'  in  front  of  commands  that
require  you  to  have  a  capital to use, and a '$' in front of commands that
require you to be non-broke for use.

CHANGES.CHAINSAW.3.0

Changes to the Chainsaw code in version 3.0

Chainsaw 3.0 has some major differences from Chainsaw 2.2.

Ships that don't carry enough crew lose effic when at sea. See info build (the
ship building section)

The  BUDGET  option  has  been  removed.  Budget is now standard.  The NEWSUBS
option has been removed. NEWSUBS is now standard.  The  MULTIFIRE  option  has
been removed. MULTIFIRE is now standard.

I took out the 'too much traffic for workers' thing, because it was dumb.

Ships of tech 310 or better can detect mines with sonar.

Conventional  missiles  launched  from  subs  are anonymous. The victim is not
notified of the launching country's identity, and the news knows naught.

In order to export something from a sector, you must have military control  of
the  sector. In order to import something from a distribution sector, you must
have military control of the distribution sector.

The chances to hit a mine are changed. See info mine and info lmine.

Two new deity commands have been added, 'disable' and 'enable', which  disable
and  enable  updates. The 'update' command will mention it if updates are dis-
abled.

When you capture a sector, all distribution info is wiped  (distribution  sec-
tor, thresholds).  Sectors just taken over are stopped (see start and stop).

The criteria for sector ownership have been changed slightly. See info sector-
ownership for information.

Countries still in sanctuary can now get telegrams and announcements.

Fishing boats and oil derricks only work in open ocean sectors.

Civs & mil may be distributed. No sector will export its last civ.

A new command, bdesignate, has been added. It allows you  to  manually  modify
your bmap.

When navigating a ship or marching a unit, you get a map of the sectors around
your ship or unit, without using BTU's.

When using map or bmap, giving the number of a ship you own instead of an area
will give you a map centered around that ship. For example,

   [##:##] Command: map 1

will  give  you a map centered on ship 1. Lmap works similarly, except you can
get a map around a land unit, and pmap gives a map around a plane.

When loading/unloading, you can give a desired  level  as  a  negative  number
instead of an amount to load/unload. For example:

   [##:##] Command: load 4 -10 food

will  attempt  to  load  or unload food as necessary to get ship 4 to 10 food.
(Similar to the syntax for enlist) See info load for details.

Land units have been added. There are many new commands for dealing with them.
Look at info Land-units for a general overview.

Sectors  that  don't  have  enough food at the update will now attempt to draw
food from supply sources. (see info supply  for  details  on  supply  sources.
Conquered  sectors will not draw food) Other sectors/ships/units will now draw
supplies (mostly shells) when they need them.

You can now give destination sectors instead of paths for  all  movement  com-
mands. For example,

   [##:##] Command: move c 0,0 10 5,-1

will  move  10 civs from 0,0 to 5,-1 via the most efficient path, the one that
uses the least mobility.

Ships/planes/units now use lcms/hcms as  they  gain  efficiency,  rather  than
using them all at once. See info build for more details.

Distribution  has  been  changed.  Each  sector  now has a distribution sector
rather than a distribution path (during the update,  the  least-cost  path  is
found and used) Also, importing & exporting via distribute now happen in sepa-
rate  phases, rather than being mingled. See info distribute and info  update-
sequence for a full description.  Read info distribute, or don't cry.

There is a document that details the update sequence. (info update-sequence)

Civs/mil/uw's are much harder to kill (how much harder is deity-settable) with
shelling or bombing or nuking.

Air to air combat is changed. Check info interception for  an  explanation  of
the interception process and a description of air combat.

Fully efficient roads now have a small mob cost to move through.

Fort  gun  range is now (7*tech factor). Damage from fort shelling now depends
on the number of guns firing. Forts get a +1 range bonus if at least 60% effi-
cient.

Sectors  can  cost  money  to designate, and may cost extra to build. They may
also take lcms or hcms to build. Show sector build will show this.

A new command, cede, allows you to give a sector or ship to  a  neighbor.  See
info cede for more details.

There are several new information commands, such as neweff and starvation. See
the info pages for details.

Sectors are damaged by combat occurring in them. See info attack for  details.

Missions  may be given to ships/planes/units, allowing them to interdict enemy
movement, support friendly attacks & defense, and other things.  See info mis-
sion for details.

Forts automatically fire at enemy ships coming within range.

Mountains can be used (poorly) as capitals. See info capital.

New options:

RES_POP:  when  RES_POP  is  enabled, the maximum number of civilians, mil, or
uw's that can be in a sector is determined by research. See info research  for
exact details.

NEW_STARVE:  when  NEW_STARVE  is enabled, the starvation ordering is changed.
Instead of losing equal numbers of each type of population (uws,  civs,  mil),
you  first  lose  uw's,  then  civs, then mil. As before, no more than 1/2 the
total population of a sector can starve in one update. Example:  if  you  have
200  uw's,  100  mil,  and 500 civilians, and no food, normally you'd have 100
uw's, 50 mil, and 250 civs after the update. With NEW_STARVE in effect,  you'd
have 0 uw's, 300 civilians, and 100 mil.

NEW_WORK:  When moving civs to or from a sector with low work, the new loyalty
and work percentage of the destination sector is computed proportionally.  For
example,  of you move 100 people from a 0% work sector to a 100% work destina-
tion sector with 100 people in it, the destination sector will  have  200  50%
work  people  in  it.  If  you  then  moved  in  100  people  with a 100% work
percentage, the sector would have 300 67% work people in it.

CARRIER_WORK: carriers will now work on damaged  planes  on  board.  It's  not
much, but it's something.

STOP:  there  are  now  2 new commands, stop & start. If you stop a sector, it
will not gain efficiency or produce for  1  update.  Start  counteracts  stop.
Census is also changed to report the production status of a sector.

CHANGES.CHAINSAW.3.3

Changes to the Chainsaw code in version 3.3

Sectors taken over have the their production stopped.  This should prevent the
"redesignate a dozen tech centers" update attack.  If STOP is not defined, the
new  sector  designation  is set to be the same as the current sector designa-
tion.

The 'file' utility now creates an all-sea world  instead  of  not  creating  a
world.

NAME
   Empire2 - Changes from the Chainsaw server to the Empire2 Server

Level: Expert

There  have  been  several  changes/fixes made to the Chainsaw code in the new
Empire2 Server.  This outlines the various changes and how  they  will  affect
you,  the  player.   Most  of  these  changes were coded by Ken Stevens  and any bug-reports in the new server should be  directed  to
him.

Ships
   -  Ships now have three letter abbreviations.
   -  "load" syntax has been changed to make it the same as the "move" syntax.
      - The following changes were made to the sonar command:
        - will only work from ships at sea
        - will only detect ships at sea
        - will now detect the shoreline
        - will only detect things if there is a straight line of water
          between the detector and the detected
        - now displays a map and changes your bmap
        - for ships with tech > 310, shows mines on the map with an X and
          puts the X on your bmap
   -  All ships (including subs) in harbors are now visible  via  the  Q*look-
      outU* command by all ships (including subs) in adjacent sectors
   -  If  a  NEUTRAL  (or worse) ship sails within your coastwatch range, then
      you will receive a telegram like this:
      TheBorg lc2 light cruiser 2 (#666) sighted at -9,-1
      This telegram is sent before any interdiction is done.  If you  want  to
      turn this feature off, then type "toggle coastwatch off".  Note that you
      can also now turn off those nuisance sonar ping detection  telegrams  by
      typing "toggle sonar off".
   -  You  may  now  tend land units which have "assault" capability (see info
      tend).
   -  "build" syntax has been simplified.  You no longer need to specify  tech
      level  to  build at (the default is your current tech level).  Also, the
       arg now comes before the  arg:

         [##:##] Command: build s 4,0 fb1
      builds a fishing boat at current tech level.

         [##:##] Command: build s 4,0 fb1 5
      builds 5 fishing boats at current tech level.

         [##:##] Command: build s 4,0 fb1 2 99
      builds 2 fishing boats at tech level 99.
   -  "show" output now shows you the total amount  of  avail  used  to  build
      something.
   -  The  Autonav  code  has  been  completely  rewritten and is dramatically
      improved.  Thanks Chad!
   -  You now get a telegram if someone loads something onto your ship  or  if
      someone unloads into your harbour.
   -  Load/Unload now tell you exactly how much stuff got loaded/unloaded from
      each ship.
   -  You can now only unload into a sector if you are friendly towards  them.
   -  The  "coastwatch"  command  now  shows  ship names!  (Empire invents the
      telescope!)
   -  The "payoff"  command  now  shows  the  distance  your  ship  has  trav-
      eled--handy for making sure you pass those critical distances.
   -  The  tech level required to build aegis cruisers has been increased from
      150 to 260.
   -  The following ships: "mc  missile cruiser", "aac aa cruiser", "agc aegis
      cruiser",  and  "ncr  nuc cruiser" have been given a new ship capability
      called "anti-missile"  This means that they will use their  anti-missile
      systems  to attempt to intercept enemy missiles aimed at any ship within
      a 1 sector radius.  Note that just like abm &  a-sat  missile  intercep-
      tion, only missiles belonging to countries you are "Hostile" or "At War"
      with will be intercepted.  Thanks Chad!
   -  Ship damage now always factors the armor value of the  ship,  no  matter
      where  the  damage comes from.  Also, whenever a ship is hit, the player
      is told exactly how hard that particular ship was hit.
   -  The "scuttle", "scrap", "mission", and "fuel" commands will  now  accept
      "l" for the unit type.  (You are no longer required to type "la".)
   -  Now  when  you  load land units onto a ship, the code will automatically
      try to supply them, and if they are out of supply, you will get a  warn-
      ing.

Subs
   -  ASW  planes  will  now fly out to track any non-FRIENDLY (including NEU-
      TRAL) sub movement.
   -  However there is a chance that the plane won't even leave the ground and
      notice  any sub movement at all.  The chance of detection is identchance
      = (1 - (1 - hitchance)^2).
   -  ASW planes will no longer detect subs they  fly  over  while  flying  an
      interdiction mission.
   -  Once  the  planes  have arrived at the sector where the sub movement was
      detected, then identchance is checked again.  If success, then the plane
      is able to identify the owner of the sub.  If the owner is neutral, then
      the player gets the message:
            np1 naval plane 1 #2 tracks TheBorg subs at 2,-6
      If the plane is unable to identify the owner of the sub, then the player
      gets the message:
            np1 naval plane 1 #2 detects sub movement in -3,-3
      If  the  ship  was  identified as HOSTILE or AT_WAR, then the plane will
      drop depth charges.
   -  If depth-charges miss, then the ship owner will get the message:
      RUMBLE... your sub in 24,0 hears a depth-charge explode nearby
   -  torp and fire will now only tell the victim that a "sub" torped them, or
      that return fire damaged a "sub" (rather than giving out detailed infor-
      mation about the sub number, type, and owner...)
   -  max sonar range has been reduced to 7 and sonar output no longer  prints
      blank lines.
   -  sonar  has  been changed in the following way: detection = (source "spy"
      value) + (target "vis" value) If the detection value  is  less  than  8,
      then sonar will just print
        Sonar detects sub #12
      If  the  detection  value is above 7, then sonar will report the type of
      sub.  Only if the detection value is above 9 will the owner of  the  sub
      be revealed.
   -  For  ASW planes flying "sonar" or "recon" missions, a similar change has
      been made.  The plane needs to pass one identchance  check  to  see  the
      type  of  sub, and needs to pass two identchance checks to see the owner
      of the sub.
   -  Note in both of the above cases, owner and type of FRIENDLY  and  ALLIED
      subs will always be revealed.

Navigation
   -  When  you "nav" or "order" your ships, they will automatically avoid "x"
      and "X" sectors on your bmap.
   -  now when you navi (or march), any new sector designations  automatically
      appear on your nav map and get added to your bmap (you no longer need to
      do a "look" to find out their designation.  Note that subs will only see
      sea, harbors, and bridges and will have to look" (and risk detection) to
      see anything else.
   -  If you hit the wrong character, navi will now display all possible  navi
      commands.
   -  You can now draw a 'M' map or a 'B' bmap while navigating.
   -  You  can  list  the ship you are navigating using 'i' and you can change
      your flagship using 'f'.
   -  Navigating using "nav", "order" or "sail" now  calls  exactly  the  same
      code  and  will thus result in exactly the same risks (mines & interdic-
      tion).
   -  Now you can type commands like this:
         [##:##] Command: nav 72 jlsruMluBursh
      That is, you can mix directions with other navigation commands.
   -  Interdiction of navigating ships now works as follows:

               1. Forts interdict.
               2. If there are any ships left, ships, land, planes interdict.
               3. If there are any ships left, marine missiles on interdiction  fire one at a
                  time until there are no ships left.

   -  There is now a new kind of diplomatic relation that you can have with  a
      country:  "Friendly"  which  falls between "Neutral" and "Allied".  This
      basically splits "Allied" into two steps: anything to do with  ships  is
      available  to  "Friendly"  nations  (nav,  load,  unload, tend, upgrade,
      order, sail, follow), whereas anything to do  with  planes  or  military
      support  is  reserved  for Allies.  This allows you to establish trading
      relationships without the necessity of  a  military  relationship.   See
      info relation for full details.
   -  If  the BIG_CITY option is enabled, then small ships may navigate, load,
      and unload in 2% cities.

Planes
   -  Planes which are less than 40% efficient can not fly.
   -  If you're tech is higher than 290, then you may not  build  planes  with
      tech lower than 150.
   -  Planes  will  only abort if they have been damaged below 80% (it used to
      be that they could abort at anything below 100%).
   -  The range of marine missiles and SAM's has been reduced.
   -  Air combat reports are now succinct tables with headers.  Much easier to
      read.  Thanks Waffen!
   -  New  command "skywatch" scans your skies overhead for satellites.  Works
      very much like "coastwatch".
   -  You can now filter your satellite output  to  list,  for  example,  only
      banks  owned  by country #7 which are over 60% efficient.  The selectors
      available are exactly the same as those used by  the  "census",  "ship",
      and "land" commands.  See "info satellite" for more details.
   -  A 75% satellite now only sees 75% of sectors (the rest are blank).  It's
      always the same 25% that are blank.
   -  All missiles are now VTOL.  In particular, this means that  missiles  on
      missions will now fire from anywhere (including on subs).
   -  Surface missiles can now be put on interdiction mission.  To distinguish
      surface missiles from anti-ship missiles, the latter have been  given  a
      new  capability  called "marine".  Surface missiles on interdiction will
      keep firing on the enemy until at least 100 damage has been done.
   -  Interdicting marine missiles will also fire on ships when they "fire".
   -  Missiles and planes flying interdiction missions will now  detonate  any
      nuclear warheads that they are carrying.
   -  When  you  "arm" a missile or plane, you will be asked whether you would
      like to program the warhead to airburst or groundburst.
   -  Missiles and planes are now limited to a maximum of one warhead  apiece.
   -  A-sats  will  now  automatically  attempt  to  intercept  any satellites
      launched by a country you're "Hostile" or "At  War"  with.   This  works
      exactly  the  same  way as ABM defense.  Also, if you launch a satellite
      over a sector which is owned by a non-ally then they will get a  message
      telling them that you have positioned a satellite over their sector.  In
      the age of advanced telecommunication such things don't go unnoticed.
   -  There is now only one formula for determining  whether  a  plane/missile
      hits  its  target  and  how  much damage it does (including abm's and a-
      sat's).  See "info bomb" for the formula.   In  particular,  planes/mis-
      siles  flying missions will now have exactly the same hitchance as those
      flown by hand.

Land Units
   -  Land units now have three letter abbreviations.
   -  Artillery must be at least 20% efficient before it can fire.
   -  The "lmine" command now allows you to lay as  many  land  mines  as  you
      want.   If  the  unit  can't carry as many mines as you asked it to lay,
      then it will just keep resupplying itself until  it  finishes  the  job.
      Also, it now costs engineers 1 point of mobility per mine laid.
   -  If land units are accompanied by engineers, then their chance of hitting
      a land mine is reduced by a factor of 3.  E.g. if there are 25 mines  in
      the  sector,  then  a land unit has a 33% chance of hitting a land mine.
      If it is accompanied by an engineer, then that chance drops to 11%.
   -  If an engineer sweeps a land mine that it cannot carry, it drops it as a
      shell into the sector.
   -  Engineers  now  sweep  a  number of times equal to 2 times the number of
      shells they can carry.
   -  The chance of an engineer finding a land mine in a  sector  is  now  50%
      time the "att" value of the unit:
                # of sweeps   chance of finding a mine
      old system   5            66%
      eng1  130    6            60%
      eng2  165    8            75%
      meng  260    8            90%
   -  You  can  now draw a 'M' map or a 'B' bmap while marching.  Also, if you
      hit the wrong character, navi will now display all possible  march  com-
      mands.
   -  Fortifying a land unit no longer clears the unit's mission.
   -  You  can  list  the  units you are marching using 'i' and you can change
      your leader using 'f'.
   -  Now you can type commands like this:
         [##:##] Command: mar 72 jlruMluBurh
      That is, you can mix directions with other march commands.

Forts
   -  Forts now get their range bonus for return fire if they're > 60%.
   -  Forts now do not cost anything to designate.
   -  You may not fire a fort which is less than 5% efficient.
   -  Forts will now only automatically interdict ships that the country would
      be  able  to  see  using  the "coastwatch" command.  Ships out of visual
      range will not be interdicted by forts.  Note that ship/ship, unit/ship,
      plane/ship interdiction was not changed, and also the "fire" command was
      not changed.  _only_ fort/ship interdiction was changed.

Sectors
   -  Bank interest is now scaled by efficiency rather than simply turning off
      below 60%.
   -  Shoot syntax has changed from "shoot 2,0 c 400" to "shoot c 2,0 400".
   -  Harbors now have the same packing bonus as a warehouse.
   -  You can now build bridges all on one line as in:
         [##:##] Command: build b 2,2 j
   -  You  are  now only allowed to cede to nations which are Friendly towards
      you.
   -  The new Empire command "strength" will show you the defense strength  of
      all your sectors (including number of land mines and reacting units from
      nearby sectors).
   -  The "test" command no longer requires there to be the commodity  in  the
      sector  (useful  if  you want to use that sector as a temporary stopover
      and you don't want the stuff to get stranded there).
   -  Shelling now factors in the efficiency of the sector into its  defensive
      bonus,  so now a 0% bank defends the same as a 0% fort which defends the
      same as a 0% road.  The formula for calculating the new defense value of
      a sector is: ((defense - 2)*eff/100) + 2
   -  The "neweff" command now checks to see if a sector has been stopped.
   -  xdist and ydist are now in player coordinates.
   -  Any interdiction of things being moved will also damage the sector being
      moved into.  Note: this will slow down bridge attacks!
   -  Deliver now gets the same 4x bonus that distribute gets.
   -  The "spy" command now gives you much more useful information:

   SPY report
   Wed Jul 26 21:10:13 1995
      sect   type own oldown eff  civ  mil  shl gun  pet food bars units planes
     29,5      c+   4      4  90  980    0  940  10    0    0    0     2      0

   -  A new option has been added to the server  called  BIG_CITY.   When  the
      BIG_CITY option is turned on, it takes lcm's, hcm's, and money to create
      a city ('c' sector), but they can hold ten times as many civs, and get a
      10x packing bonus for moving civs.
   -  It  used  to be that a gold mine could not hold more than 999 dust.  Now
      all sectors are allowed to hold 9999 of anything, but  it  is  now  only
      _production_ which is limited to 999 per update.
   -  Now  the  "starvation" command will let you check for starvation on land
      units or ships.

Info
   -  The info pages are now organized into subjects.  Type "info" for a list.
   -  The  budget  command  has been changed so that now you may choose not to
      pay maintenance costs.  Also, "mil" on ships/planes/units has been moved
      from  the maintenance costs for those items to the "Military" section of
      the budget.

Commands
   -  Broke countries are now allowed to use all commands except for the  fol-
      lowing:

      arm  assault  attack board bomb build convert disarm drop enlist explore
      fire fly grind harden launch lmine mine paradrop recon  satellite  scrap
      shoot sweep torpedo treaty upgrade work
   -  Broke  countries used to be prevented from using the following commands,
      but will now be allowed to use them:

      demobilize lload llookout load lookout lradar lrange lretreat ltend lun-
      load  march  mission  morale  mquota  navigate  order qorder radar range
      retreat sail sonar sorder spy supply tend transport unload unsail

Update
   -  If you can not afford to maintain your ships/planes/units or you  choose
      not  to  maintain  them  using the "budget" command, then they will lose
      ETU/5 % efficiency at the update.  Also, if you are broke at  the  point
      of  the  update  when  it comes time to build something, then that thing
      will not be built.  In short, the only way you can go broke  now  is  by
      having lots of mil to pay.

Communication
   -  The new commands "flash" and "wall" permit instant communication between
      friends and allies respectively.  Type "info flash" and "info wall"  for
      more details.
   -  The  new  command  "toggle" can be used to instantly inform you when you
      receive a new telegram.  You can also use "toggle" to temporarily  block
      flash  messages.   To  find  out  which clients support this, type "info
      Clients".
   -  The server will now correctly report how many telegrams you  have  wait-
      ing.
   -  The  new  command  "pray" lets you send a telegram to the Deity.  Also a
      telegram from the deity is no longer called a BULLETIN, it is now called
      a TELEGRAM.
   -  The new command "motd" lets you see the "message of the day" (login mes-
      sage) again.
   -  The buggy commands "mail" and "wmail" have been removed from the server.
      If you want to use them, you'll have to use pei.
   -  You  can  now  specify which countries you'd like to see in your "power"
      report.
   -  New "report" command lists number ranges rather than "advanced",  "supe-
      rior", etc...

Combat
   -  Defense against attack, assault, and paradrop is now exactly the same.
   -  If  attack  odds  are > 90%, then defensive support is no longer called.
      This will put a stop to most shell-draining techniques.
   -  You can now specify how many troops you want to board with.   Also,  the
      code  now  always  forces  you to leave at least 1 mil on your ship when
      boarding.  You can also board from any sector type and with  land  units
      having  "assault"  capability.  You may not board with more mil or units
      than the boarded ship can hold.
   -  You may not attack with supply, security,  artillery,  or  anti-aircraft
      (flak capability) land units.
   -  Attacking land units & mil used to be taken out of the sectors/ship they
      were attacking/assaulting/boarding from.  This caused  endless  problems
      (including  stranded  units).  In the new code, mil and units stay where
      they were until they have finished attacking.  The battle is assumed  to
      take  place  along  the  "border"  between  the  two sectors.  Thus, the
      attacking mil & land units will be vulnerable to shelling and  attacking
      while you are answering the attack prompts.
   -  If,  while  you  are  answering  the attack prompts, anything happens to
      either the sector you are attacking, or the mil & units you are  attack-
      ing  with,  then you will be notified ("land unit #3 damaged from 80% to
      50%", "Your mil in 3,1 damaged from 180 to 12", "defending mil has  been
      increased  from 10 to 250").  You will also be notified in this way if a
      bridge collapses, one of your attacking  sectors  was  taken,  you  were
      shelled,  your  enemy abandoned the sector you were attacking, your land
      units reacted to fight another battle, battle  and  given  a  chance  to
      abort  your  attack.   If  for  some  reason it is no longer possible to
      attack (e.g. you now own the sector, or a  bridge  collapses)  then  the
      attack will be automatically aborted.
   -  The  sub-prompt  for  both the "attack with" and the "move in" questions
      has changed to [ynYNq?].  The meanings of these 6 answers are:

               y - yes this unit
               n - no this unit
               Y - yes all units in this army
               N - no all units in this army
               q - quit attack
               ? - print this help message

   -  The server will now add up the mil you saw and the enemy land units your
      scouts  saw, and based on this info, it will estimate a defense strength
      of the enemy.  If your scouts didn't see the  efficiency  of  the  enemy
      units,  then it will assume that they were at 100%.  Based on this esti-
      mated defense strength, the server will calculate an  estimate  of  your
      success odds for you and if these estimated odds are less than 50%, then
      the server will ask you if you're sure you want  to  continue  with  the
      attack.   These  estimates  are  made  before support is calculated, and
      before the enemy reacting units have reacted, so it will not be particu-
      larly  accurate.   However, if by the time you've finished answering all
      the attack prompts something has happened which has made your odds  much
      worse  than  you  expected  (e.g. your cavalry got shelled or your enemy
      beefed up his mil), then this will  give  you  a  chance  to  abort  the
      attack.
   -  Immediately  after  a battle is won (i.e. before any move-in sub-prompts
      are asked), 1 mil (first choice) or 1 land unit (second choice) is auto-
      matically moved into the taken sector.  Not only does this put a defini-
      tive stop to shell-draining tricks, but it also resolves what was a  big
      problem  in  the old code of the taken sector being owned but not occup-
      pied for a period.   This  problem  resulted  in,  among  other  things,
      stranded  land units.  It is impossible to strand a land unit in the new
      code.
   -  I have added a new option to the  server  called  INTERDICT_ATT,  which,
      when  enabled,  calls the usual interdiction routines against mil & land
      units moving into the victim sector after an attack.  The  same  chances
      of interdiction apply as in "move" and "march".  The mil get interdicted
      sector by sector, and the land units all at once.
   -  In the new attack code, it is much harder for a unit to  fail  a  morale
      check.  The new chance (recalculated after each hit) is (retreat% - unit
      efficiency).  Thus, a land unit which has a retreat  percentage  of  60%
      and is now 50% efficient, will have a 10% chance of retreating with each
      hit.

Important bugfixes
   -  Missiles on subs will now fly missions against enemy planes  (in  chain-
      saw, the missiles simply vanish).
   -  Subs now only interdict subs if they have sub-torp ability (in chainsaw,
      sb1's will interdict sb1's).
   -  Missiles will no longer hit subs.
   -  Your airport now needs to be at least 60% eff in order  to  fly  bombing
      runs  from  it (in chainsaw you can bomb from 40% airports, but only fly
      and recon to 60% airports).
   -  You can't sweep, hit, or lay sea mines in a harbour.  You  can't  sweep,
      hit,  or  lay  land  mines on a bridge.  (In chainsaw, your ally can hit
      your land mines in your harbour.)
   -  It is no longer possible to accidently go broke through any of the  fol-
      lowing  commands:  build,  convert,  demob,  des,  harden, upgrade.  (In
      chainsaw it's easy to accidentally go broke through one  of  these  com-
      mands.)
   -  Much of the "attack" function was rewritten to check for "special cases"
      which can result in lost military and units.  Thanks Chad!
   -  The range of missiles on interdiction mission was half of what it should
      be.  this is now fixed.
   -  If  you  typed  "realm #2 0:10,0:10", it would change realm #0.  This is
      now fixed
   -  If you downgraded your relations from Allied to Neutral, then the  other
      country would downgrade their relations towards you to Hostile.  This is
      now fixed.
   -  You used to have to log out and back in again to stop being broke.   Now
      your status will be updated as soon as you get the money (well, one com-
      mand after to be exact).

NAME
   Empire3 - Changes from the Empire2 server to the Empire3 Server

Level: Expert

There  have  been  several  changes/fixes  made to the Empire2 code in the new
Empire3 Server.  This outlines the various changes and how  they  will  affect
you,  the  player.   Most  of  these  changes were coded by Ken Stevens  and any bug-reports in the new server should be  directed  to
him.

Sectors
   -  The delivery and distribution stuff was removed from the output of "com-
      modity" and each column was widened to 5 characters (to  accomodate  the
      new system where sectors are now allowed to hold up to 9999 of stuff)
   -  Mountains  will now mine gold at 3/4 the rate that gold mines do (thar's
      gold 'n them thar hills!)
   -  Mountains can now only hold 1/10th the population of normal sectors.
   -  The mobility cost to move into a sector has been changed from:
          cost = (mcost - eff) / 5
        to:
          if (mcost < 25)
            cost = (2 + (3 - mcost) * eff) / 5
          else
            cost = (mcost - 20 * eff) / 5

      OLD SYSTEM: eff   0%  100%     NEW SYSTEM: eff   0%  100%
                    +  0.2   0.0                   +  0.4   0.0
                    m  0.4   0.2                   m  0.4   0.2
                    ^  5.0   4.8                   ^  5.0   1.0
      Note that this means land units can attack 100% mountains now, so  there
      will  be  a  tradeoff for the defender--either they can have a low effi-
      ciency mountain that costs more mobility to  attack  but  gets  a  lower
      defense  bonus,  or  they can have a high efficiency mountain that costs
      less mobility to attack but gets a higher defense bonus.
   -  New conditional query "coastal" which gets set when you take a  "census"
      of the sector.  Type "cens * ?coast=1" to get a list of all of your sec-
      tors which are adjacent to  water  (and  thus  vulnerable  to  assault).
      Ships
   -  -  The  size of "ts1 trade ship 1" was reduced to 100 lcm, 50 hcm, $1500
      (from 200 lcm, 100 hcm, $2500).  Most players were waiting  for  ts2  so
      this is a nice way to deal with that.
Planes
   -  In the old system, planes would be charged either 10 mobility (intercep-
      tors), 12 mobility (escorts) or 20 mobility (the rest) per flight.  This
      cost  was then multiplied by (100 / eff) with the restriction that plane
      mobility could not go below -32.  Planes flying  missions  were  charged
      only  1/4 of this.  In the new system, planes are charged a base rate of
      5 mobility to prepare for takeoff.  On top of this, they are  charged  a
      flight  cost  which  is  either 10 (interceptors and escorts) or 20 (the
      rest), however this flight cost is scaled down according to  the  length
      of  the flight--it is multiplied by (flight length) / (max plane range).
      The flight cost is then scaled by (100/eff) with the restriction that  a
      plane  can't  go below -32 mobility.  Planes flying missions are charged
      1/2 of this.
   -  The mobility of a plane will now go down by  one  point  for  every  two
      points  of damage it took from air-to-air combat, to a limit of -32 mob.
      This is to simulate the high mobility cost of air-to-air combat, and the
      fact that air-to-air combat is more effort for low tech planes.
   -  SAM  interception  is  now  separate  from  plane interception; for each
      attacking plane, if it cost at least $1000 to build, then one  SAM  will
      be  launched  at  it.   After  SAMs have been fired, fighter planes will
      intercept what's left over.
   -  The restriction that high tech nations can not build low tech planes has
      been removed (the above changes address the f1 SAM-soaking problem).
   -  Marine  missiles  on  interdiction now fire at a single ship rather than
      the whole fleet.  They pick the ship which is the most valuable  accord-
      ing  to (cost to build) * efficiency.  Furthermore, marine missiles will
      only launch at a ship if the ship cost >= $1000 to build or  if  it  can
      carry land units or planes.
   -  Sectors  which  your  planes fly over when they fly missions will now be
      added to your bmap.
Land Units
   -  There are three new land  units:  'cavalry  2',  'light  infantry',  and
      'aau1'.   Here's  the  basic  scheme.   The  old  cavalry are an average
      between the somewhat weaker cav1  and  somewhat  stronger  cav2.   light
      infantry  are  half  the size of and slightly fastar than inf1's. 'aau1'
      come at the same tech as Zepplins and let  low  tech  countries  try  to
      throw rocks at low tech planes...
Maps
   -  You now have 50 realms.
   -  Each  country  now  has two bmaps, their 'working' bmap and their 'true'
      bmap.  The true bmap contains only information put there by the  server.
      The  working  bmap  also  contains information put there by the bdes and
      sharebmap commands.  The 'bmap' command  usually  displays  the  working
      bmap  unless  the  player specifies 'bmap  true'.  If the players
      working bmap becomes corrupted somehow, then they can type 'bmap 
      revert'  to  revert  their  working  bmap back to their true bmap.  This
      change was necessary to prevent abuse of  the  new  'sharebmap'  command
      (which  compares  the  players  true bmaps when determining whether they
      overlap).
   -  There is a  new  command  "sharebmap    ".   If    is
      friendly towards you and your 'true' bmaps already share enough informa-
      tion in common, then your bmap will be added to their  bmap.   For  more
      details see 'info sharebmap'.
Information
   -  The  new  info  page "info Mobility" gives the formulas for all mobility
      costs in the game.
Communication
   -  If someone else was the last person to use your country, then  when  you
      login you will get a message like:

               Last connection from: Mon Nov 13 04:48:04 1995
                                 to: Mon Nov 13 05:13:12 1995
                                 by: children@RedDragon.Empire.Net

   -  If the game is a blitz, then the 'players' command will list other coun-
      tries which are logged on.  This will cut down on the 'is  anybody  else
      logged  on?'  announcements.   Note that for players, 'last command' and
      'user@hostname' are not printed (only deities get to see this stuff).
   -  You can now read old announcements which you've already thrown  away  by
      typing:

      SYNTAX
         [##:##]% wire 

      This  works  much  in  the  same  way as news.  The server automatically
      deletes all announcements older than 7 days.
   -  New server commands 'toggle sync', 'toggle  async',  and  'sync'  permit
      client-server database synchronization.
   -  Before you type a telegram, you will now see:
          Enter telegram for Fodderland
          undo last line with ~u, print with ~p, abort with ~q, end with ^D or .
          1024 left:
        The new tilde escapes work very nicely.

Options
The following options have been made standard:

NAME
   Empire4 - Changes from the Empire3 server to the Empire4 Server

Level: Expert

There  have  been  several  changes/fixes  made to the Empire3 code in the new
Empire4 Server.  This outlines the various changes and how  they  will  affect
you,  the  player.   These were coded as the Wolfpack project, and bug-reports
should be sent to .

   Changes to Empire 4.2.11 - Sun Sep  1 09:54:59 MDT 2002
    * Added compile option for the Mac OSX architecture.
    * Fixed bug in cargo where unit array was indexed by shp_maxno
      instead of lnd_maxno.

      server.
    * Can't buy land units into enemy headquarters.
    * Added sabotage command and commando unit.
    * Spies moving by themselves will not trigger interdiction.
    * Fixed error in map distance calculation that caused errant
      interdiction.
    * Ships going under -127 mobility will be set to -127 mob and
      not roll over to positive mobility.
    * Corrected plane cost in info Maintenance.

    * Updated player idle counter during read prompt so players
      wouldn't be kicked off during long flashes or writing telegrams.
    * LOSE_CONTACT will work as advertised.
    * Allied units marching through 0 mobility conquered sectors
      are charged at least LND_MINMOBCOST.

   Changes to Empire 4.2.10 - Fri Aug 10 17:25:05 MDT 2001
    * Assault can reinforce own sector when SLOW_WAR is enabled.
    * emp_client no longer converts lines into tags but still verifies executes,
      pipes, and file redirect match players input.
    * Added pboard command to capture enemy planes in your territory.
    * Declaring war when at Sitzkrieg won't return relations to Mobilizing.
    * Declaring war won't charge money if you're already Mobilizing.
    * Added multiple territory fields.
    * "show nuke build" displays the proper avail.
    * retreating land units will only retreat to sectors owned by the player
      that owns the unit.
    * added hard cap of "250 + easy" to limit_level.
    * education p.e. calculation divides edu constant by etu per update.

    * Corrected formula for likelihood of plague in info Plague.
    * Fixed files to correctly size map and bmap files from econfig file.

   Changes to Empire 4.2.8 - Mon Oct  9 17:35:35 MDT 2000
    * Fixed range in radar.t and Sector-types.t.  Maximum range at infinite
      tech is 16.
    * Changed so that player can't drop civilians into occupied sectors.
    * Fixed bug that crashes update if etus/update is less than 8.
    * Fixed sometimes not reporting overflights

    * Updated order of firing flak in Flak.t.
    * Fixed 80% efficient planes on ships must be maintained.
    * Fixed initial MOB_ACCESS check thread sleep time was set by an uninitialized
      variable.
    * Removed "TEMPORARILY DISABLED" message from mission command for escort

    * Added comments on setting update policy in econfig file.
    * Added logging of cases where write extends data file by more than one id.
    * Option MARKET is turned off by default.

   Changes to Empire 4.2.7 - Fri Mar 10 18:41:04 PST 2000
    * Added new NF_SACKED flag to indicate when a country has had it's
      capital sacked.  This flag is only cleared when the country actively
      redesignates it's capital using the "capital" command, and changed
      capital.t to reflect this (no more re-sacking after an update if the
      country doesn't reset and repeating until they are out of cash.)
    * Added land unit to edit command for planes.
    * Added nuketype to edit command for planes.
    * Changed so that if the leader of a group of units is a train, the
      railways are used for bestpath instead of roadways.
    * Changed mission command to also print reaction radius of reserve
      missions when set for land units.
    * Changed Flak.t to reflect guns having to be loaded onto a land unit
      for flak to fire.
    * Changed so that visitor countries cannot change their name or password.
    * Changed so that you cannot upgrade deity planes, ships or units.
    * Changed so that you know where missions are flown from.
    * Changed so that the airport owner you fly a mission from is informed.
    * Changed so that preperations for takeoff are reported to the owner of
      the sector, ship or unit a plane is taking off from if it is not owned
      by the owner of the plane.
    * Changed so that when a sector reverts during a guerrilla revolt, the
      mobility is not reset.  When MOB_ACCESS is not enabled, this used to mean
      you would always get at least an updates worth of mobility.  With
      MOB_ACCESS, sectors that reverted during the update were useless, since you
      got no mobility for a long time.  This fixes that problem, and makes che
      more useful as well.
    * Changed so that air defense missions don't always send up every plane in the
      area, but instead always send up at most two times the number of incoming
      planes (for each interdicting country.) This helps to stop 1 plane from
      stripping the mobility from 25 air defense planes all at once, but doesn't
      limit it to n+1 as there is for regular interception.
    * Clarified deity reversion of sectors in Sector-ownership.t
    * Clarified production efficiency and added pointer to "show sector cap"
      in Product.t
    * Clarified nuketype selector for planes in Selector.t
    * Clarified that fortifying units does not affect mission status in info
      pages for mission and fortify.
    * Clarified fuel syntax upon error in fuel command in empmod.c.
    * Cleaned up comments causing minor complaints in some builds.
    * Fixed bug in loans where you could collect on proposed loans.
    * Fixed production command to be more accurate (though it *still* has some
      rounding errors, it's better.)
    * Fixed potential memory leak in air defense missions.
    * Fixed bug where you couldn't pinbomb some commodities if other commodities
      didn't already exist in the sector.
    * Fixed bug where you couldn't build 0 crew planes without military in the
      sector.  (This is different from needing at least 1 military to build all
      planes that need a crew which introduced another related bug earlier.)
    * Fixed bug where scrapping land unit 0 could cause erroneous transfer
      messages to be displayed for deity owned planes.
    * Fixed bug where land units on ships in a sector taken over were blown
      up or captured.
    * Fixed bug where planes on ships in a sector taken over were blown up
      or captured.
    * Fixed bug in sdump printing origx and origy in deity coordinates.
    * Fixed bug in satellites showing wrong sectors (sometimes) when using the
      optional arguments.
    * Fixed bug in launch showing wrong satellite target (showed asat instead
      of the target satellite.)
    * Fixed bug where you could gain information not normally available using
      the "fire" command to determine sector type information.
    * Fixed bug in market/trade creating extra money when loans are taken out.
    * Fixed problem with land units not being reported sunk after being sunk
      on a ship that was nuked or wastelanded in a sector.
    * Fixed problem with Spies.t using "llook" instead of "llookout".
    * Fixed problem in lwp/arch.c including jmp_buf.h instead of setjmp.h
      on some Linux boxes.
    * Fixed problem with plague infection being way too high in cities when
      the BIG_CITY option is enabled.
    * Fixed bug in edit command getting confused with arguments.
    * Fixed bug in ask_move_in_off asking you to move in a negative number of
      troops (hey, it could happen. :) )
    * Fixed bug in add command not keeping flags or relations initially correct.
    * Fixed bug in torpedo command sometimes telling victim about torpedo
      sightings even when way out of range.
    * Fixed bug in spy command not reporting planes in adjacent sectors, as well
      as not formatting them properly when reporting them.
    * Fixed bug in satellite with noisy transmission causing a potential
      crash of the server with non-100% efficient satellites.
    * Fixed potential crashing of the server during satellite display when not
      calculating distances to ships and units correctly.
    * Fixed bug where planes in non-allied sectors, ships and units could be
      used on missions.
    * Fixed bug where planes on the trading block could be used on missions.
    * Fixed bug where planes and units that get traded don't have mobility set
      correctly when using MOB_ACCESS option.
    * Fixed bug which made security units virtually useless.
    * Fixed access times and mobility not being set right when building planes,
      ships, units, bridges and bridge towers when MOB_ACCESS is enabled.
    * Fixed minor formatting problem with launch of satellites.
    * Fixed minor formatting problem with planes with greater than 999 tech.
    * Fixed minor formatting problem with ships with greater than 999 tech.
    * Fixed problem with "llook" showing up in TOP info file.
    * Fixed problem with lwp Makefile choking on NT builds with clean target.
    * General cleanup of potentially ambiguous statements.

   Changes to Empire 4.2.6 - Fri Jun  4 05:55:20 PDT 1999
    * Added "TECH_POP" as an option where technology costs more to make
      as your population grows past 50K civilians.  It is disabled by
      default.
    * Changed "produce" command to accurately print what the true p.e. is.
    * Changed "update" command to display if mobility updating is enabled for
      MOB_ACCESS option.
    * Fixed bug where toggling off the coastwatch flag also turned off
      forts firing on hostile ships coming into range.
    * Fixed bug where assaulting your own land would violate any treaties
      you have where assaults are a violation.
    * Fixed bug where all planes (even those without need for a crew, such
      as missiles) needed at least 1 military to build.
    * Fixed bug where when a ship sinks during the update due to lack of maint,
      land units and planes on it were left stranded.
    * Fixed bug where when a land unit dies during the update due to lack of
      maint, land units and planes on it were left stranded on it.
    * Fixed bug where nukes could be lost due to MOB_ACCESS updating mobility
      while arming.
    * Fixed bug in "show sector capabilities" not showing products correctly.
    * Fixed bug in "show tower build" printing "bridges" instead of "bridge
      towers".
    * Fixed bug in sectors that don't revolt not showing up as lost items.
    * Fixed bug where maps with an X of exactly 200 is not drawing third line.
    * Fixed bug where MOB_ACCESS was not updating the mobility just before
      the update.
    * Fixed bug in the way treaties are examined and sometimes produce
      wrong results.
    * Fixed edit to allow creating negative mobility for sectors.
    * Fixed setsector to allow creating negative mobility for sectors.
    * Fixed bug where when writing out the value of a sector that had
      negative mobility and was damaged in combat, mobility was being
      set back to 0.
    * Fixed Taxes.t info page to reflect that captured civvies only pay
      1/4 taxes.
    * Fixed Technology.t info page to reflect TECH_POP option.
    * Fixed navigate.t info page to reflect that only ships in the fleet
      in the same sector that are fired upon have damage divided up.
    * Made techlists toggle on by default (so things are shown in order of
      technological advances.)

   Changes to Empire 4.2.5 - Mon Mar  1 06:42:24 PST 1999
    * Added optimization to increasing mobility to check if an object is
      already at max mob, just return since it can't be increased.
    * Added "-ltermcap" for client libs for hp build (it was already in
      hpux build.)
    * Added clearing of telegram flags after the update so that the next
      telegram is flagged as new and not part of the update.
    * Fixed Update-sequence.t to reflect MOB_ACCESS.
    * Fixed bug where fortification amount was not being limited to
      maximum mobility for land units (land_mob_max).
    * Fixed bug where land unit fortification strength was being calculated
      by using 127 instead of land_mob_max.
    * Fixed bug where scrapping land units was creating military.
    * Fixed description of sect_mob_neg_factor in econfig file.
    * Increased speed of PT boats.

   Changes to Empire 4.2.4 - Tue Feb  2 05:47:44 PST 1999
    * Added check to make military values match up correctly for land
      units.
    * Fixed bug in doconfig not putting ipglob.c in the right place.
    * Fixed bug where attacking deity sectors will violate a treaty.
    * Fixed newspaper.t information file.
    * Fixed potential bug in fixing up timestamp information when restarting a
      game with MOB_ACCESS turned on.
    * Fixed bug in explore command not setting mobility to correct
      value when MOB_ACCESS was enabled.
    * Fixed bug in enlist setting mobility incorrectly sometimes.
    * Added doc/backup file for deities which recommends how backups and
      restores of the data directory should be done.

   Changes to Empire 4.2.3 - Wed Jan 13 06:02:35 PST 1999
    * Added linux-pthreads target and build for using pthreads under Linux.
    * Added NO_FORT_FIRE option which disables the ability of forts to
      fire when enabled.
    * Added more error checking and recovery for corrupt data files.
    * Changed alphapos target to alpha-pthreads for better clarity.
    * Changed fairland to allow 0 sector distance to other islands and
      continents (James Risner)
    * Changed "frg" and "dam" land unit stats to "rng" and "fir" so they
      match the way ships are described (since this is how they really work.)
    * Changed Unit-types.t to now describe "rng" as firing range of a unit,
      and "fir" as the number of guns that a land unit fires.
    * Cleaned up misc. build warnings.
    * Changed artillery damage to be 5 + d6 per gun firing from just d6
      per gun firing and updated Damage.t to reflect this change.
    * Changed artillery firing ranges to be like ships ranges - divided
      by two, and modified them to make more sense.
    * Changed artillery units to be "slightly" :) more powerful.
    * Changed "cavalry" unit to tech 30 and lowered mil content to 20.
    * Changed "artillery" unit to tech 35.
    * Changed so that guns are no longer required to build units, and
      that guns must be loaded onto artillery units for them to fire.
      Client developers note: the show command has not changed yet to
      remove the 'guns' column (since guns are no longer required) but
      will in a future revision (possibly 4.2.4) so "be prepared" for
      "show land build" to change. :)
    * Fixed landunitgun to handle all the damage calculations like it should.
    * Fixed bug sinking planes when the ship they are on sinks.
    * Fixed bug destroying planes when the land unit they are on is destroyed.
    * Fixed bug where land units could fire support without enough military.
    * Fixed bug in abandoning sectors by marching out a land unit where it
      would not let you sometimes (uninitialized variable problem.)
    * Fixed gets problem in files.c (James Risner)
    * Fixed bug in determinig operations range of a ship.
    * Fixed bug in building planes where you could manufacture military.
    * Fixed warnings in threading package(s).
    * Fixed fire.t to reflect new firing changes.
    * Fixed lstat.t to reflect new firing changes.
    * Fixed sstat.t to reflect the way things really work.
    * Fixed Ship-types.t to reflect the way things really work.
    * Fixed the way shutdowns work to hopefully better protect data files.
    * Fixed bug in attacking when sector mobility is less than 0 and it would
      prompt for attacking with a negative amount of military.
    * Fixed typo in fire.t stating wrong parameters for firing from a sector.
    * Fixed bug in client when it prompts for country name it was putting
      an extraneous end of line on the end that needed to be stripped off.
    * Fixed problems running on Linux running on an Alpha machine.  Thanks
      to Rocky Mountain Internet and Jeremy A. Cunningham for giving us time
      on a machine to work out the bugs.  (Note that the only build that
      works on Linux/Alpha is the linux-pthreads)

   Changes to Empire 4.2.2 - Sun Dec 27 12:46:34 PST 1998
    * Added some code optimizations into the update code when building paths.
    * Added some new cacheing for building paths to help speed up updates.
    * Added so that you can use "name" and "password" with the change command
      as well as "country" and "representative".
    * Added flag to power command so that if you are a deity and enter
      a negative number of countries you want to see, you see the power chart
      for that many countries without power numbers on the next line.  Only
      useful for deities that want to see the chart un-broken up by that line.
    * Added new functionality to fortify command.  You can now use a negative
      fortification value to cause the unit to be fortified and leave at
      least that much mobility on the unit. I.E. "fort * -67" will fortify
      all units and make sure the mobility of each unit doesn't go below
      67.  If the mobility is already below that level (or equal) the unit
      is left unchanged.
    * Added that the realm command prints "Realm #n is x:x,y:y" after
      you set a new realm.
    * Added TREATIES option and enabled it by default.
    * Added "no depth-charging subs" and "no new land units" treaty
      clauses.
    * Added Trannie Carter's basic client fix to use fgets instead of gets.
    * Changed market and command to only print the lowest priced lot of
       each given commodity by default.  If you specify "all" it shows
       all lots on the market, and if you specify a specific item, it shows
       all lots of that item type.
    * Changed start command to only write out sector if it changed.
    * Changed stop command to only write out sector if it changed.
    * Changed how plane names were changed on server startup if the
      PLANENAMES option was enabled.
    * Changed move command to use standard askyn function for abandoning
      sector prompt.
    * Changed plane overlight sightings to take stealth into account,
      and if the planes managed to evade all flak and interceptors, they
      are not marked as "spotted" over enemy sectors.
    * Changed all units with the supply flag to have their marching speeds
      based on efficiency since that is their purpose.  What this means is
      that supply units and trains are more effective at 100% than at 10%
      (just as fighting units are more effective at 100% than at 10%, but
       their effectiveness is determined by how well they fight, not how well
       they "run away, run away!" :) )
    * Changed so that flash toggle is on by default for POGO at setup
      time.
    * Changed so that when a sector is taken, all land units owned by the
      current owner are treated as planes are during takeovers (i.e. there
      is a pretty good chance they are blown up, and if not, they change owner
      to the attacker and are beat up pretty good.)
    * Fixed treaties to work again.
    * Fixed bug in taking over land units not using correct pointer (can
      cause a crash or data corruption.)
    * Fixed collect command to wipe deliver and distribution information
      correctly.
    * Fixed potential bug in bmap not working when destination bmap has
      blank spaces in it.
    * Fixed bug in shark command not getting right nation structure.
    * Fixed bug in server where empty commands (for example, all spaces
      or tabs) were being reported as bogus commands.  They are now just
      ignored.
    * Fixed bug in scrap not dropping land units off of scrapped units carrying
      them.
    * Fixed bug in news where boarding of land units was reported backwards.
    * Fixed bug in calculating new people when growing them during an update.
    * Fixed missing -ltermcap in HP/UX build.
    * Fixed setsector to limit mobility to 127 not 255 (255 was being caught
      later and being reset to 0 anyway)
    * Fixed Sector-types.t to show a '' instead of a '/' for wasteland,
      since that is what it really is.
    * Fixed retreat.t documentation to reflect the "retreat upon failed
      boarding" flag.
    * Fixed bug where satellites were not orbiting the world during the
      update.
    * Fixed bug in torpedos being too smart.  They knew how to jump over
      land! :)  Now the "line_of_sight" routine is used to determine if a
      torpedo has a straight path to the destination.  If it doesn't, the
      torpedo no longer jumps over land, but instead slams into it.  This was
      an interesting bug because you could torp ships on the other side of
      a very skinny island as long as they were in range, even if there was
      no sea route possible.
    * Fixed bug when pinbombing and you run out of an object to pinbomb (land
      units for example) but you still have to pick something to bomb.  For
      ships it worked ok (just aborted that it couldn't find any more ships)
      and this was fixed for land units and planes.
    * Fixed server crashing bug when flying a plane and not carrying
      any cargo.
    * Fixed bug in move losing commodities when it runs out of room in the
      destination sector.  Goods are now attempted to be returned to the
      start sector, and apporpriate steps taken if the start sector is no
      longer available.
    * Fixed march to prompt you before you abandon a sector you own by
      marching out the last land unit.
    * Fixed check functions to only check the relevant portions of the structure
      and not the timestamp info that doesn't affect how the object functions.
    * Fixed bug in spy command that always told you if a spy unit was in a
      non-owned sector.
    * Fixed bug in displaying of land unit missions not showing correct land
      unit range.
    * Fixed bug in wire command where new announcements that you read at
      the last second don't get wiped out properly.
    * Fixed bug where announcement file could be corrupted by very long lines.
    * Fixed bug where bmap was not set when player was told what kind of
      sector they were attacking (this was an old abusable bug that was
      removed long ago to fix the abuse, and it's been fixed in a non-abusable
      way finally.)
    * Fixed bug where change command would warn you about monetary and
      BTU costs, but not prompt you to break out if you didn't want to really
      change your country name.
    * Fixed bug in sub-launched nukes that are intercepted being reported in
      the news incorrectly.
    * Fixed bug in load where you could abandon a sector and not know it by
      loading your last civilians or military onto a ship.
    * Fixed potential memory leak in autonav code.
    * Fixed potential bug where you could possibly determine if a sector is
      owned or not using one way plane missions.
    * Fixed Damage.t info page to properly show damages for planes and
      land unit shelling.
    * Fixed deliver.t to include syntax for command.
    * Fixed country.t to include syntax for command.
    * Fixed bug where ships on orders were not adding radar information to
      the bmap during an update.
    * Fixed bug where ships on sail were not adding radar information to
      the bmap during an update.
    * Fixed bestownedpath code to use the bmap properly.  Note this is a very
      important bug fix.  When navigating a ship, players are no longer given
      free information that they would not normally know.  For example, if you
      try sailing your ship off into uncharted areas of your bmap, the bestpath
      code will only use as much information as you have on-hand (i.e. your
      bmap) to plan out your path for you.  If you have no information on an
      area, it just keeps forging on, until bumping into something.  Of course,
      after the initial exploration through an area, the bmap will be set and
      used for all future sailings through that area.  Harbors and bridges
      are still checked for construction worthiness if you know where they
      are (i.e. they are on your bmap.) (Overall, what happened before
      was that the bestpath code would route your ship around islands that
      you didn't even know were there, and you could use various commands
      to see how that ship was going to sail during the update and thus you
      gained information that you wouldn't normally know.)
    * Merged bestpath and bestownedpath and wrote new wrappers, "BestShipPath"
      and "BestAirPath" to use it properly.  It is also good to note that
      bestownedpath is used to determine paths for ships and for planes,
      and that best_path (which uses the A* algorithm) is used for all land
      based paths, and that the two are never interchanged.
    * Removed "jet recon" plane (it slipped in during the PLANENAMES conversion,
      and RECON was never used before.)
    * Removed extraneous "resnoise" and "resbenefit" functions and combined
      the two for setresource and setsector commands.

   Changes to Empire 4.2.1 - Tue Nov  3 12:56:20 PST 1998
    * Fixed problem with global/plane.c not defining last structure element
      properly, and thus causing crashes when accessing certain plane
      routines.  This happened during the move to make the PLANENAMES option
      run-time configurable.

   Changes to Empire 4.2.0 - Thu Oct 29 06:27:15 PST 1998
    * Bumped rev to 4.2.0 since this is a major release (the server is now
      run-time configurable for just about everything and is released under
      the GNU GPL.)
    * Put in official licensing information.
    * Re-arranged and commented the econfig (Empire Configuration) file.  The
      auto-generated "data/econfig" file is now pumped out chock full of
      comments (which may or may not be useful.)  Since the server is
      pretty much fully run-time configurable (MAXNOC is not, but it gets
      a default of 99 anyway) deities will probably be spending more time
      in the config file.
    * Added server support for building under NT, including mods from
      Doug Hay and Steve McClure to get the server building and running
      under NT. (This was built using MSVC++ 5.0 on NT 4.0 and command
      line "nmake nt")
    * Added Doug Hay's ntthread.c implementation for NT threading.
    * Added max pop column to "show sector stats" output.
    * Added lboard command for boarding land units from sectors.  Only raw
      mil can board land units, and only mil and land units aboard the unit
      being boarded fight back.
    * Added GODNEWS option.  When enabled, the deity giving people stuff
      is shown in the news.
    * Added bridge tower sector ('@')
    * Added BRIDGETOWERS option.  When enabled you can build bridge towers
      from a bridge span.  You can then build bridge spans from the tower.
      If the tower is destroyed ( <20% eff) bridges connected fall unless
      supported on the other side.  You can only build bridge towers in open
      water not adjacent to land and other towers.  Expensive.
    * Added plains sector ('~') - Max pop is 1/40th regular sectors, and
      it is deity creatable only (can't redesignate unless you wasteland it
      with a nuke :) )
    * Changed "info all" to no longer use printdir, instead it just uses the "all"
      info page which contains this information.
    * Changed so you can now load up to 2 spy units onto non-land unit carrying
      submarines if the LANDSPIES option is enabled.  Useful for sneaking up
      to shore and spying on your neighbors.
    * Changed so spies unloaded from ships are not given as gifts, they are just
      unloaded quietly.
    * Changed build command to handle building towers ("build t")
    * Changed show command to show tower stats ("show t b")
    * Changed reject so you can now reject things from any country except
      deity countries (this now includes sanctuary countries and visitor
      countries you don't want to deal with)
    * Changed ndump to dump nuclear stockpile ID as well.
    * Changed flash so that if someone allied to you is either not logged on or
      not accepting flashes, you are notified.  This is info you could gain
      otherwise since you can see other countries that are allied to you via
      players.
    * Fixed bug in news command when HIDDEN mods are enabled.
    * Fixed distribute command to only write out to the database if we
      actually changed the sector (i.e. if we really moved the dist
      center, we write.  Otherwise, it makes no point.)
    * Fixed threshold command to only write out to the database if
      we actually changed the sector (i.e. if we really changed the
      threshold, we write.  Otherwise, it makes no point.)
    * Fixed - population growth and truncation in "Update-sequence.t" info
      file is now clearer
    * Fixed the way fortify takes mobility away from a land unit if
      engineers are present.
    * Fixed bug in buying commodities at the last minute not resetting the
      time correctly in all situations.
    * Fixed bug in building nukes where it would always ask if you tried
      building more than one at a time.
    * Fixed bug where if you put (either by building or by transporting)
      more than 127 of one type of nuke in a sector, they all got lost. A
      negative wrapover sort of thing.
    * Fixed ndump to print # of stockpiles dumped.
    * Fixed ndump.t to reflect changes
    * Fixed bug in build command that didn't account for EOL characters.
    * Fixed bug where you could use planes to drop conquered populace
    * Fixed bug in distribute command in how it checked for current distribution
      sector.
    * Fixed pr_flash and pr_inform to no longer send messages if the player
      is still in the process of logging in (i.e. not in the PLAYING state)
    * Fixed report command output for deities.
    * Fixed bug in nuclear damage either taking out submarines when it
      shouldn't, or not taking them out when it should.
    * Fixed bug in loading units that are carrying units onto other units
      (note that it doesn't happen since only HEAVY units can carry other
      units and that check works, but that might change some day, and we
      don't want units carrying units to be carried by other units, etc. :) )
    * Fixed info pages to reflect new sector types.
    * Fixed info pages to reflect new spy unit capabilities.
    * Fixed show commands to only show trade ships if the TRADESHIPS option
      is enabled.
    * Fixed build command to only allow building of trade ships if the
      TRADESHIPS options is enabled.
    * Fixed up some definitions located in many places used for checking
      sectors for navigation rights.
    * Fixed power.t to correctly describe NEW_POWER formula.
    * Made HIDDEN option run time configurable.
    * Made LOSE_CONTACT option run time configurable.
    * Made ORBIT option run time configurable.
    * Made SAIL option run time configurable.
    * Made MOB_ACCESS option run time configurable.
    * Made FALLOUT option run time configurable.
    * Made SLOW_WAR option run time configurable.
    * Made SNEAK_ATTACK option run time configurable.
    * Made WORLD_X and WORLD_Y run time configurable.
    * Made MARKET option run time configurable.
    * Made LOANS option run time configurable.
    * Made BIG_CITY option run time configurable.
    * Made TRADESHIPS option run time configurable.
    * Made SHIPNAMES option run time configurable.
    * Made DEMANDUPDATE option run time configurable.
    * Made UPDATESCHED option run time configurable.
    * Made LANDSPIES option run time configurable.
    * Made NONUKES option run time configurable.
    * Made PLANENAMES option run time configurable.
    * Removed SMALL_SERVER stuff (unused baggage)
    * Removed trading post sector ('v')

   Changes to Empire 4.0.18 - Thu Sep 24 06:54:27 PDT 1998
    * Fixed bug in aircombat where planes in flight could intercept air
      defense planes and take no damage (i.e. they got to fight twice,
      once for free.)
    * Fixed bug in freeing memory after performing missions that could crash
      the server (it mainly happened after an interdiction mission using
      planes and escorts, where some escorts came from airports that didn't have
      bombers going up.  Freeing the leftover escorts was crashing the server.)
    * Fixed bug where you could load non-existant units if you were allied
      with country #0.
    * Fixed bug where you could pin-bomb a plane with itself.
    * Fixed bug where satellites over a bridge may get killed if the bridge
      is sunk.
    * Fixed bug where land units on a ship in the same sector as a bridge
      that is splashed may get sunk.
    * Fixed bug where planes on a ship in the same sector as a bridge
      that is splashed may get sunk.
    * Fixed doconfig with correct empire site text.
    * Fixed major problem with abms not firing, and sometimes crashing
      server.
    * Fixed bug in land units counting up loaded units wrong.
    * Fixed doconfig makefile to have doconfig.c as a dependency.
    * Fixed bug in resetting commodities (the comm_uid was not being
      properly set.)
    * Fixed bug in repaying loans not working correctly (the l_uid was not
      being properly set.)
    * Fixed bug in buying items from the trading block not allowing you
      to due to a perceived change in item status.
    * Fixed bug in mfir.c where a bogus input to a target could crash
      the server.
    * Fixed bug that after you read telegrams new telegrams may not send
      an inform message (the old telegram flags were not cleared.)
    * Fixed bug where fort support distance calculations are calculated
      twice instead of just once.  This bug caused a lower percentage
      of support fire than designed.
    * Fixed bomb.t to reflect land unit changes.
    * Put in some integrity checking for planes returing from bombing runs.
    * Added ability to edit land unit that a land unit is loaded on in
      edit command.
    * Consolidated bridgefall code into "knockdown" function (this code
      existed in at least 3 places, and was different in all of them.)
    * Subs returning fire are no longer reported in the news.
    * Visitor countries can now use the 'motd' command.
    * When trying to use a visitor country, if it is in use, you are not told
      by whom, just that it is in use.
    * Optimized (slightly) support fire from forts not getting supply and
      shells if not needed (out of range)
    * Updated Education.t
    * Modified (increased) chances of hitting mines slightly.
    * Removed unused variables from shp_check_mines.

      Larsen.  They are described with other changes below.
    * Fixed bugs in the following commands that allowed two cooperating
      countries to create infinite numbers of any commodity and/or cash

      countries.
    * Fixed bug in anti command not stopping sectors when they revolt.
    * Fixed bug in set_coastal function not counting bridge spans as
      water based sectors (after all, the land is still a coastal sector,

      before.)
    * Fixed bug in neweff not reporting stopped sectors.  It now (correctly)

      ships were selected.
    * Temporarily disabled escort missions until a fix is found. They are
      randomly crashing the server.

      that has a bridge collapse are being sunk.
    * Fixed bug in update/produce.c when a sector overflows it's capacity
      on production.
    * Fixed bug in produce command reporting incorrect costs (sometimes).
    * Land units on ships will now try to draw supply from the ship they
      are on.

   Changes to Empire 4.0.13 - Mon Mar  2 11:04:28 EST 1998
    * Fixed bug in distribute when world sizes are other than 64x32
    * Fixed bug in getcommand (not really a bug, just made it work like

      again)
    * Fixed building of POSIX threads on Alpha running Digital Unix.
    * Fixed line_of_sight prototype in sona.c
    * Fixed fairland not to conuse stupid C++ compilers.

   Changes to Empire 4.0.11 - Tue Feb 10 10:53:10 EST 1998
    * AIX build seems to only work with gcc right now (but at least that works)
    * Vax Ultrix (vaxultrix) build should work now (hopefully) out of the box.
    * Took out autosupply of airports when bombing or dropping shells.
       (This was the only commodity this was done for, and it was creating
       problems since supply is still somewhat broken somewhere)
    * Included Curtis Larsen's, Markus Armbruster's and Sverker Wiberg's
       submitted patches, which collectively included cleaning up most
       of the server prototypes and bogus declarations.  Many thanks.

    * Fixed bug where fleets were being interdicted but the damage was being
       spread to ships not in the same sectors.
    * Fixed but in market when buying goods without enough cash.
    * Planes in orbit over airports are no longer fixed up during updates.

    * Fixed doconfig.c to use STDC instead of multi-level #ifdefs.
    * Fixed bug in parse.c that was screwing up double quotes in conditional
       arguments.
    * Military in a sector now only produce up to maxpop, just like civvies
       and uw's.  No more stuffing 6K mil into a mountain to max it out.  You
       can still hold more mil there over the updates, but the extras just
       won't produce anymore.
    * Fixed bug in shark that allowed you to shark up loans even if you couldn't
       cover the debt.
    * Fixed bug in day of week calculation for server up time in common/keyword.c
       that is used for gamedays.
    * Documented what happens to standing military in collect.t when you collect
       a sector.
    * Documented mountains only holding and using 1/10th of the normal sector
       population in Sector-types.t.
    * Fixed documentation on ship's firing ranges in fire.t to be less
       ambiguous.
    * Updated nukes in nuke.t
    * Added apropos command (thanks to Mike Wise)
    * Added case-insensitivity to the info command (thanks to Mike Wise).  If
       there are two files of the same name, and you don't get a complete match,
       then whichever file is found first in the directory is used.
    * Changed documentation in wantupd.h

   Changes to Empire 4.0.9 - Sat Apr 19 23:01:51 EDT 1997
    * Fixed dump info pages that were getting formatted funny.

    * Fixed bug in harden not printing correct values.
    * Fixed bug in creating/moving/etc. nuclear stockpiles.
    * Fixed bug where subs were trying to torp commodities moving on land when
       on interdiction.  (This was funny ;-) )
    * Fixed bug in "move" where you could keep a sector even after someone else
       took it from you.
    * Budget now correctly reports the # of units being built.
    * Mil on units & ships are now reported as normal military costs, not
       ship or unit maintainence costs in budget.
    * Fixed bug in update code where taxes could potentially be initialized
       incorrectly (affected budgets too.)
    * Fixed bug in nat.h header so that it uses SCT_MAXDEF instead of a fixed
       number (that was incorrect.)
    * Fixed bug with trains - they needed the xlight flag to carry planes.
    * Revamped and improved flak.
    * Added "Flak" info page.
    * Added "Fallout" info page.
    * Fixed repay/offer/consider to all need a capital to be used.
    * Fixed bug with air defense missions not running when not AT WAR.  They now
       fly when HOSTILE.
    * plane/ship/unit short names are all now 4 characters, padded if needed.
    * pdump/sdump/ldump/ndump now just print the short name for the type.
    * sdump now has ship name at very end in quotes.
       These were done at the request of some client developers for ease of use.
    * Fixed extra space in the dump output.
    * Fixed fallout - not quite so nasty anymore.
    * Fixed fallout - things on ships/units are damaged now.
    * Fixed and balanced planes/ships/units/nukes in conjunction with each other.
    * Fixed bug in doconfig.c calculating wrong s_p_etu sometimes.
    * Fixed bug where harbors weren't being used to resupply.
    * Fixed bug where selling units loaded with planes and units wouldn't take
       the loaded planes or units - they are now dropped.
    * Fixed bug in arm/disarm where you could arm/disarm planes on the trading
       block.
    * Deities can now remove things from the trading block/market.
    * Fixed bug in "work" not charging engineers enough mob.
    * Fixed bug in "work" not adding teardown and buildup avail costs together.
    * Subs no longer need mobility to return fire when fired upon.
    * Fixed "reset".
    * Fixed bug in "trade" allowing 2 players to pay for the same item, but only
       the last player gets it.

       the midnight "raid and sell" abuse down. :)
    * Fixed "show plane cap" to move the last column over 1 more where it should
       be.
    * Fixed timestamps to be updated for units/planes on ships/units that move,
       since those units/planes move too.

   Changes to Empire 4.0.8 - Wed Feb 26 23:00:51 EST 1997
    * Fixed bug in nstr_exec that was wiping out the previous conditional.
       This was major because it affected timestamp values which are more
       than 65535.
    * Fixed bug in sdump.c for typo in reporting the trade ships origin.

   Changes to Empire 4.0.7 - Mon Feb 24 22:48:54 EST 1997
    * Fixed bug in aircombat.c when calculating the air combat odds.  Negative
       numbers were screwing things up good...
    * Fort sector's coordinates are no longer printed when auto-firing at
       ships.
    * Subs can now surface and fire deck guns (again)  They can also be
       hit by return fire when doing so.
    * Fixed bug in setting of plane attack and defensive values so that
       negative numbers don't keep going further negative.
    * Fixed incorrect military control calculation in the sell command.
    * Trading posts are no longer required to sell goods from.  You can sell
       from harbors and warehouses now too.
    * Spy now prints out the owner of land units you see when spying.  Before
       this was assumed to be sector owner, which is no longer true.
    * Loading land units now prints out what was loaded onto each unit,
       just as loading ships do.
    * Added fallout, coast, c_del, m_del, c_cut and m_cut to dump output.
    * Added "GO_RENEW" option.  This option means that gold and oil resources
       are renewable.
    * Added "lost_items_timeout" config variable, and set the default to
       48 hours.  This determines how long lost items stay in the lost items
       database.
    * Fixed land unit names to be more consistent.
    * Fixed mission.t info page.
    * Fixed bug in that if mission_mob_cost was set to 0, even negative
       mob units should be able to be put on missions.
    * Removed restriction on things needing to be at least 60% to be put
       on a mission.  Note that while you can put them on missions at < 60%
       now, when trying to do the mission, it still checks the eff.  This
       is to help in automatic setup (build, put on mission, forget) instead
       of having to come back repeatedly.
    * Spies caught in Neutral or Friendly countries cause the Neutral or
       Friendly country to go Hostile towards the owner of the spy.
    * Tweaked ammunition numbers for artillery units.
    * No more automatic declarations of War should be made.  You will go
       hostile, but since going to war doesn't increase your countries
       defenses, and is purely political, it is left to the player to go
       that final step.
    * Fixed bug in trade that wasn't incrementing the time if last second bidding.
    * Fixed bug in "lmine" that was crashing the server if the land unit was
       out of mobility.
    * Fixed buy so that if you specify a product, you can only bid on that
       type of product.
    * Added "lost.t" info page.
    * Added "lost items" database (EF_LOST)
    * Fixed bug where you could move in allied forces after an attack if they
       bordered the victim area.
    * Fixed nstr_comp to deal with values > 16 bits coming in from
       client for comparisons.
    * Changed last minute market/trade timers to increment 5 minutes.  2 minutes
       was too quick.
    * Fixed decode in lib/common/nstr_subs.c to deal with NSC_TIME better.
    * Commented out the logging of the market checking in server/marketup.c,
       lib/commands/buy.c and lib/commands/trad.c  It was generating lots of
       pretty much useless data that made parsing the server.log file more
       more difficult than it needed to be.
    * Fixed crashing bug in ldump.
    * sdump, ldump, ndump, pdump and dump now print out the current
       timestamp on the "DUMP XXX" line.
    * Fixed denial of service bug in lib/player/accept.c in
       player_find_other function.
    * Fixed bug in shark reporting incorrect buyer of the loan.
    * Fixed bug in sdump.c (case 0 should have been case 10)
    * ldump and sdump now always print the fuel column if asked for,
       even if opt_FUEL is turned off.  In the case that it is turned
       off, the fuel is listed as 0.
    * Added "timestamp" field, which is updated every time an item is
       changed.
    * Fixed up the Clients.t info page.
    * sdump now prints trade ship building origin.
    * sdump now always prints name even if SHIPNAMES isn't defined.  If
       it is not defined, then the name is empty.
    * Added "timestamp" to info/Concepts/Selector.t
    * Added some more relevant info to info/Server/Empire4.t
    * Fixed Infrastructure.t info page to reflect the fact that infrastructure
       is no longer torn down when a sector is re-designated.
    * Fixed sell.t to more accurately reflect the time-delay market.
    * Fixed read.t and wire.t to reference accept and reject.
    * Fixed reject.t not referencing accept command.
    * Fixed collect.t to more accurately reflect what goes on when collecting
       sectors.
    * Fixed financial.t to reflect defaulted loans.
    * Fixed dump.t, sdump.t, ldump.t, ndump.t, pdump.t to reflect new
       timestamp info.
    * Fixed "census.t" (had incorrect reference to "info syntax" instead
       of "info Syntax".

   Changes to Empire 4.0.6 - Thu Jan 16 11:33 EST 1997
    * Increased damage from depthcharges because on increased damage from
       torpedos.  Sub frange decreased to be more balanced with destroyer frange.
    * Intelligence reports (spy) on units will now report the estimated number
       of mil on the unit.
    * Fixed equation for ship visibility so it will drop as tech increases.
    * Added new commands sdump, ldump, pdump, and ndump to dump data on ships,
       land units, planes, and nukes.
    * If fields are provided, dump will only supply those fields requested.
    * Decreased speed of subs.
    * When options NO_LCMS or NO_HCMS are set, those commodities are no longer
       required for infrastructure improvements.
    * Units that lose an assault or a boarding attempt from a ship will no
       longer swim back to the ship they came from.
    * Units that take extra casualties will no longer lose all their mil at
       once.
    * Infrastucture is retained when redesignating a sector.
    * Dieing spies will no longer crash the server.
    * Units, planes, and ships must have mobility to perform missions.
    * Units on ship being scrapped are transferred to harbor.
    * Food is no longer autoloaded onto units when they are built.
    * Fixed show plane stat to show correct range.
    * Infantries now take damage at same rate as casualties.
    * Fixed bug with hap_fact.  Having more happiness now helps with fighting
       che.
    * Fixed anti to write back target country so che will continue to fight
       when they survive.
    * Fixed llookout to show correct estimate on number of mil on unit.
    * Added buildable architecture "hp".  This type will build the server on
       a HP/UX machine using the standard compiler instead of gcc.

   Changes to Empire 4.0.5 - Thu Dec 12 10:28:48 EST 1996
    * Fixed bug in update/distribute.c where pathcost was not being called with
       the MOB_ROAD argument (and thus distribution costs could be GREATLY

    * Put in change in lnd_mobcost in lndsub.c
    * Put in new nuke costs in nuke.c
    * Put in fix so that total work can only be done by the max pop. No more extra
       civvies tossed in will do it anymore in human.c.
    * Put in fix for src/util/Makefile - beefed it up.
    * Put in fix to show where your ship is when it gets shelled in mfir.c.

    * Changed mountains to get an automatic "2" for defensive bonus in attsub.c
    * Fixed consider.t
    * Fixed repay.t
    * Fixed offer.t
    * Fixed "offer" and "consider" not being legal commands in player/empmod.c
    * Fixed Damage.t
    * Fixed sstat.t
    * Fixed lstat.c, pstat.c and sstat.c
    * Fixed cutoff command in cuto.c
    * Fixed attack value in attack_val in lndsub.c
    * Fixed lload in commands/load.c
    * Fixed defense_val in lndsub.c - Made it a minimum of 1, so that units will
       always fight until dead or retreating.  0 makes them get stuck.
    * Fixed update/deliver.c - no delivery of non-oldowned civvies (or anything
       else for that matter.)
    * Fixed llook in commands/look.c
    * Fixed che bug in subs/nstr.c
    * Fixed bug in strv.c by overcompensating by 1 food per sector (minute amounts
       of people would starve.)
    * Fixed update/human.c - feed_people rounding problems (I hope.)
    * Fixed morale problem in update/land.c
    * Fixed count_bodies in attsub.c
    * Fixed lnd_mobcost.
    * Fixed subs/land,plane,ship.c to handle sunken units and planes correctly.
    * Fixed interest rate in commands/offe.c
    * Fixed bug in buy.c.
    * Put in DEFENSE_INFRA soption o you can turn on/off the use of the defensive
       infrastructure.  When off, the defensive infrastructure is the same
       as the sector efficiency, and you can't improve it.  This is OFF by
       default.
    * Fixed Empire4.t
    * Added Wolfpack.t
    * Land units are now built with a default reaction radius of 0.
    * Changed name of lt artilleries to "lat" from "lart" so you can now build
       "lar"s again.
    * Lowered the speed and firing range of pt boats.
    * Lowered the initial att strength of cavs from 1.5 to 1.3 (they were TOO
       powerful.)
    * Changed the max mob gain defaults of units/planes to 1.0 and ships to 1.5
       (This is * ETU_RATE, so it is equal to ETU_RATE for units/planes and
        1.5 * ETU_RATE for ships.)
    * Conquered civvies only pay 1/4 taxes.
    * Railways don't get torn down when you rebuild sectors anymore (but roads
       and defenses do (if enabled.)

   Changes to Empire 4.0.1 - Wed Aug 28 11:35:40 EDT 1996
    * Added "extern double tradetax" to check_trade in trad.c
    * Improved description of data directory in build.conf
    * Fixed bug in attacking land units that retreat so they now get
       charged mobility for attacking.
    * Fixed dump to report road, rail and defense of a sector at the end.
    * Fixed doconfig bug in not checking the right directory to see if the
       "data" directory existed or not before trying to create it.
    * "change" now works for sanctuary countries.
    * Fixed the description of "sinfrastructure".
    * Added more info to "Infrastructure".
    * Units/planes are no longer reduced to 75% when bought from the trading
       block.
    * Supply units were slowed down to the speed of infantry units.
    * Trade-ship payoffs have been lowered to 2.5, 3.5 and 5.0
    * Bars interest is up to $250 per 1K again.
    * Civ taxes were raised back up to a 10:1 mil/civ tax ratio (was 20:1)
    * Fixed various info pages.
    * Fixed bug in people not getting truncated when broke (this was thought
       to be fixed, but wasn't. Now it is, dammit!)
    * Fixed bug with units marching across oceans (scuba gear not included. ;-) )
    * Market/trade taxes and trade ship payoff figures were added to version.
    * "cede" has been removed as a default command.
    * Makefile rule was fixed for depend build.
    * Fixed bug in mapdist not taking world edges into account nicely enough.
    * Added a "scuttle" order for autoscuttling trade ships.  Makes using them
       easier.  Cleaned up scuttle code while in there.
    * Fixed bug with scuttling a ship with units on it not scuttling the units
       too.

   Changes to Empire 4.0.0 - Initial release
    * Initial Wolfpack release - Long live the Wolfpack!!!!
    * Cleaned up the build environment.  Now all that is needed is to edit the
       build.conf file, answer the questions there and type "make " to
       build for a specific architecture.  Thus, no more reliance on gnumake
       or special shell scripts.
    * We are now shipping the pre-built info pages with the server for those who
       Don't want to build them.  You can also still just type "make" and have
       the info pages build, but it doesn't completely work (i.e. rebuild new
       Subjects) if you don't have perl5 installed.
    * Put in the "help" command that does the same thing as "info".
    * Removed C_SYNC.  This is done for 2 reasons.  1) None of us like it or
       wish to support it.  2) We envision a better scheme for doing similar
       things will come along.
    * Put in MOB_ACCESS - This allows real-time updating of mobility.
    * Put in MARKET - This is the time-based market (yes, still teleports,
       but it's not as bad as it was.)
    * Lots of the documenation has been updated, but there is more to do.
    * Added NO_LCMS, NO_HCMS and NO_OIL options.  When any of these options are
       enabled, you don't need any of that type of material to build things.
       If NO_HCMS is enabled, you don't need HCMS to build bridges, you need
       lcms.  If both NO_HCMS and NO_LCMS are enabled, then you don't need
       any materials to build a bridge.
    * There is no mobility cost for assigning missions.  But, there is also
       no longer any benefit for being on a mission either.
    * Damage is the same for all commodities (people too.)  This means you
       can deity shell/bomb sectors again.
    * Units are now dependant on tech.  What this means is that their statistics
       now increase with tech.  In addition, there is only 1 type of each basic
       unit now (i.e. just "cavalry" instead of "cavalry 1", "cavalry 2", etc.)
       This reflects the idea that as you learn more, you learn how to not only
       build better units, but you learn to build units better. :)  This also
       opens the door for a "lupgrade" command along the same lines as the
       "upgrade" command for ships.
    * Units now have a minimum mob cost for attacking a sector.  Marching
       mob costs have not changed.
    * Starting units have been removed.  This means that at the beginning, people
       may live a little longer since their neighbor can't come visiting quite
       as quick.
    * Shells are no longer required to build units.
    * Mil are no longer required to build units.
    * Mil are no longer an intrinsic part of a unit.  They are now a loadable
       commodity.  The way a unit's defense/att bonuses work now are
           attack = (att * mil * eff)
           defense = (def * mil * eff)
       In addition, when a unit takes damage, both the eff and the mil go
       down.  You can quickly toss in new hacks, but you need to wait to repair
       the unit at the update.  Thus, you can now look at unit's efficiency
       as their training.
    * You need at least 1 mil on a unit to march it (spies are the exception.)
    * Units always react if in range and they have the mobility, no matter
       what their efficency.
    * Units may now march anywhere - in your own sectors, deity owned sectors
       or allied sectors, with 1 exception, spies.  Also, your units can get
       trapped if your ally declares non-alliance with you while your units
       are still in his country.)
    * Units always march at their speed, efficiency doesn't matter.
    * LANDSPIES was added - This creates land unit based spies.  Spies may march
       anywhere, with a chance of getting caught (except in allied territory.)
       See "info Spies" for more info on them.
    * Planes may now be based out of allied airports.  Landing planes on
       ships/sectors you do not own no longer changes thier owner.  You can only
       land on owned/allied sectors/ships, and you may only
       fly/bomb/para/recon/drop from owned/allied sectors.  So, if a country
       you are allied with goes hostile at you, your planes are now stuck there.
       Note that if you are using an allied airport, their commodities get
       sucked up, not yours (obviously.)
    * Planes are now tech-based.  Their statistics increase as their tech
       increases.  Deleted extraneous planes.
    * There is a new toggle, "techlists", which allows you to see what you
       can build/stats/capabilities sorted by tech instead of groupings.
    * Ships are now tech-based.  Their statistics increase as their tech
       increases.  Deleted extraneous ships.
    * Che can now be lessened by making happiness.  If you have more happiness
       than your conquered populace, they don't fight as hard or recruit as
       much.  If you have less than them, they fight harder and recruit more.
       It's not much though - it ranges from 2.0 in your favor to only 0.8
       against you (whereas it was always 1.0 before.)  So, it definitely
       favors the attackers to make lots of happy now.
    * Bridgeheads can only be built on coasts.
    * Players command was fixed so you only see allies, and don't get
       approx #'s of players anymore.
    * POSIX threads support has been added.
    * The attack bmap bug has been fixed.
    * BTUs regenerate 3 times faster now.
    * GRAB_THINGS is off by default.
    * Big nuclear bombs are back, and FALLOUT has been fixed and enabled
       as a default (you couldn't make wasteland before with FALLOUT, now
       you can.)
    * You can now deliver military and civilians.
    * Added SHIP_DECAY option - off by default (turns off ships decaying out
       at sea if not enough mil.)
    * The reverting owner bug has been fixed in territory, thresh, dist
       and deliver.  There are probably more, and when found, will be fixed.
    * The "sectors don't starve when stopped or broke" bug has been fixed.
    * The "people never get truncated" bug has been fixed.
    * Added infrastructure to sectors.  What this means is that a sector
       can now have it's mobility improved by building both roads and
       railways.  It also means that a sectors defense is now based on the
       defensive infrastructure you build into the sector (no more intrinsic
       better defenses based on the sector, you determine which sectors are
       defended heavily, and which aren't.)
    * The defensive value of a sector no longer relies on the efficiency of
       the sector. Instead, it relies on the defensive efficiency of the sector.
       Thus, the "production" and "defensive" aspects of sectors have been
       separated.
    * "show sect stats" now shows the maximum defensive value for sectors.
    * Changed sector structure to take floats for off/def values so we can use
       a base of 1 instead of 2.
    * Added "improve" and "sinfrastructure" to support the infrastructure
       concepts.
    * Added L_TRAIN units which can only travel along railways.  Very fast on
       efficient railways, slow on non-efficient ones.
    * Added the ability for units to carry other units.
    * Fixed census (shortened up "fallout" and "coast" to "fall" and "coa".)
    * Forts only cost $500 to build and 100 hcms now (since they don't get any
       better defenses automagically.)
    * Modified "show sect build" to show the costs for building up the
       infrastructure of a sector.
    * Changed "spy" and the satellite recon stuff (which shows sector stuff for
       spyplanes too) to show the new infrastructure stuff, rounded of course.
    * Added Drake's info->html scripts, with some modifications, so you can
       now type "make html" and have your info pages built as html files too.
       This adds a new directory, "info.html", to the build tree.
    * Modified upgrade so that planes and land units may now be upgraded.
    * Added pstat command to list the statistics of your planes.
    * Added lstat command to list the statistics of your land units.
    * Added sstat command to list the statistics of your ships.
    * Added nmap command to show a map of your sectors after their new
       designations have taken place.

Comments from Dave Pare

I've  been  deity of seven or eight games, and each time I learn something new
about how far I should go, and how active a role I should take.

There are several things a deity should take into account.

 1)  Bug policy.  When a player says that a bug bit him, how do you handle it?
     Since  I  used to hack on the game at the same time players would play, I
     used to have a nasty bug policy.  That is, if a bug bites  a  player,  he
     loses.   It is very difficult to verify if a player really did lose those
     1000 gold bars from that bank because of a bug.  Also, whenever a  player
     had  something  bad  happen  to  him,  he'd yell BUG.  All too often, the
     player just did something stupid.

     If a player ever found a good bug (and reported it in a timely  fashion),
     I'd  give  him  some  kind  of reward.  The reward was generally material
     enough to encourage them to report bugs, but not too much  so  the  other
     players  complained.   If through use of this bug the player manufactured
     too many goodies for himself, I acted to redress the balance immediately.

     This whole case is only interesting when the Deity knows the Empire code,
     and can identify bugs as such.

 2)  Unskilled players.  It's tough watching your friends lose  in  an  Empire
     game.  Helping just a little by giving information, or by giving a teensy
     bit of assistance is BAD.  Empire is NOT a game of socialist care for the
     needy;  it's  more  like survival of the fittest.  Players should sink or
     swim on their own.  If you help a novice, you're deliberately hurting his
     opponent.   Some  players will lose, and as Deity you'll have to stand by
     and watch this happen.

 3)  Answering random prayers.  If you DO help someone,  help  them  in  rela-
     tively  minor  ways.  Do things like fill in some ocean, etc.  Don't give
     away commodities -- except perhaps food.  Whatever  you  do,  don't  give
     tech,  military hardware, civilians, military, or any information at all!
     The game is very stingy with information, and you should be too.

 4)  Security.  Make SURE that nobody else has access to the data directories.
     There  are  always players who will do anything to win.  If you help them
     control themselves by making the data  completely  unavailable  --  watch
     those  dump  tapes  too -- you'll be doing their moral fiber and everyone
     else a favor.

Remember, as Deity your job is to make the  game  fair.   Don't  hose  players
(unless  they  cheat  -- and you catch them!)  and don't give out information.
Information is very important in Empire, and as Deity you've got access to all
of  it.  Be careful in what you say, and how you leave your terminal at night!

Unless you've got nothing else to do, a Deity should  keep  player  communica-
tions  to  a  minimum.   Handling special player requests gets tedious after a
while; make players pay for Deity assistance.  One game I suggested  that  the
only  way  players  could  get the Deity to fill in ocean sectors, zap plague,
etc, was to offer a real-life sacrifice to the deity -- a few bottles of  good
beer, for example!  I got perhaps a dozen bottles, and managed to greatly cur-
tail player requests at the same time!

In summary, an Empire game should be between  players.   Any  time  the  Deity
helps  anyone,  Deity intervention starts becoming a factor in the game.  As a
Deity, you absolutely can't go wrong if you do nothing at all  except  routine
game maintenance.

NAME
   Hidden - The HIDDEN option

Level: Expert

The following commands are restricted when the HIDDEN option is in play:

   power:  Will only display your country's power. Other nations never show up.
   report: Will only report on contacted countries, and no status (active/flux).
   relat:  Will only display contacted countries.
   news:   Will only show news about contacted countries (except for headlines).
   accep:  Will only display contacted countries.
   tele:   Only allowed with contacted and deity countries.

A  country  is  'contacted' with a successful spy, look, coastwatch, or recon,
when an attack is made, or when you are the victom of  an  attack  or  if  you
receive a telegram.

It  possible  for  contact  to be one sided. If you contact someone, they must
also contact you in order to obtain information from you. If you want  someone
to be able to contact you, you can send them a telegram.

Tech  and  research bleed only comes from contacted countries, so it's in your
best interest to explore as much as possible.

Because of the difficulty of tracking past news, news cannot be used  with  an
argument  under  this  option. Once the news is read, it cannot be read again.
This may change in the future.

If the LOSE_CONTACT option is in play, contact is lost after three  update  of
no  contact.  Contact  can  be maintained by the same methods described above.
It's important to note, however, that contact is retained by RECEIVING a tele-
gram, not sending one.

NAME
   History - Empire Revision History

Level: Expert

   1985 PSL Empire, Peter Langston

   Naturally, the original creator (or at least the last surviving
   implementor) of Empire is Peter Langston.  He distributed the
   game that we all wanted to hack on, but naturally enough he
   didn't give out the source!  (he wasn't dumb...he probably knew
   what we'd do to his code)

   1986 UCSD Empire 0.x, Dave Pare

   Made Empire multiplayer with fixed update times.  Added hexmap, planes, nukes,
   satellites, ships, market, distribute, and updates.

   Jim Reuter (and his PDP/11 decompiler) provided Dave Pare with a large
   quantity of amazingly readable decompiled code.  His contribution
   came at a time when Dave's interest in reverse-engineering was
   flagging, and it provided what was necessary to create the
   original UCSD Empire.

   David Muir Sharnoff was responsible for promoting the early
   development of Empire 0.X.  Without David it is unlikely if Empire
   would have escaped UCSD!  He took on the onerous task of managing
   the source, creating mailing lists, applying patches, and generally
   making the early versions of UCSD Empire releasable -- they
   sure weren't when they left Dave Pare's hands...

   The rest of the folks who contributed to the early versions did
   so with code and/or ideas.  (If I've forgotten anyone, let me know!)
   They appear in chronological order.

   The following people (listed in alphabetical order) have contributed
   to the development of BSD Empire 1.1.  Without these people, BSD
   Empire would never have happened.  Thanks also go to the XCF at the
   University of California, Berkeley, for providing the facilities on
   which we performed this herculean task.

   1995 Empire 2.0, Dave Pare

   emp_player, emp_tm, and emp_update, were consolidated into one program
   called emp_server.  A threads package called "lwp threads" was used to
   manage the player threads.  Many options were made standard.  Kevin Klemmick
   added HIDDEN and NEWPAF options.  Many options were made standard.
   These are the people who submitted patches for Empire 2.0:
                  Chad Zabel (3 letter abbrev's, & autonav)

                  Julian Onions

   1995 Empire 2.1 beta, Ken Stevens

   Organized info pages, wrote a "configure" script, made minor
   improvements to many commands, rewrote missile, navigation, and march
   code.  Consolidated launch/bomb and missile/plane interdiction so that
   hitchance and damage is the same whether it's a mission or done "by
   hand".  Added collateral damage, interdiction nuke detonation,
   "friendly" trade relations, BIG_CITY, ATT_INTERDICT,
   Consolidated sail, navi, and order.  Added toggle, flash, wall,
   shutdown, strength.  Other contributers:
                  Chad Zabel (ship anti-missile defense)
                  Julian Onions (runtime configuration)
                  Sasha Mikheev (linux port)

   1995 Empire 2.2 beta, Ken Stevens

   Completely rewrote attack, assault, board, and paradrop.  Added
   "players", "skywatch", "disarm", tend land units.  Other contributers:
                  Craig Leres
                  Janjaap van Velthooven (IRIX port)
                  Ken Huisman (RCS source managemant)

   1995 Empire 2.3, Ken Stevens

   After running a series of playtest games, Ken fixed all known bugs in
   the server, organized and rewrote alot of documentation (including
   this info page) and released the Empire2 server out of beta.

   1995 Empire 3.0, Ken Stevens

   Empire 3.0 implemented the C_SYNC RFC, a powerful platform independent
   client-server protocol for synchronizing the client database with the
   server database.  The Empire 3.0 server was released with the Empire
   Toolkit written by Kevin Morgan, a portable C library which parses the
   C_SYNC messages from the server into a database for the client.  Thus,
   clients can link with the Empire Toolkit and be confident that when
   the server gets upgraded, their client will still work.  Note that the
   C_SYNC protocol is asynchronous so, in particular, players will be
   able to watch their neighbours sail ships past their coast etc...

   1996 Empire 4.0, Wolfpack (http://www.empire.cx)

   A group of people got together to form a new server project.  This project
   is a new project, and is a complete takeoff from the Empire 3.0 server
   project.  There are many additions and some subtractions from the 3.0
   code base.  The Wolfpack is headed up by Steve McClure and consists of the
   following people:

                           Mark Ballinger
                           Geoff Cashman
                           Bill Frolick
                           William S. Kaster
                           Pat Loney
                           Steve McClure
                           Richard Moss
                           Walter Smith
                           Sam Tetherow
                           Yannick Trembley
                           John Yockey

   1998 Empire 4.2, Wolfpack (http://www.empire.cx)

   The above authors (Dave Pare, Jeff Bailey, Thomas Rushack, Ken Stevens
   and Steve McClure) agreed to re-release the source code under the GNU
   GPL.  The source was already freely released to the public, but any
   copyright issues (such as gaining permission from Phil Lapsley for the
   A* code and removing any other copyrighted code which would violate
   the GPL) were cleared up, and the licensing information was put in
   place to keep the server source free forever.  Yee-haw!

   In addition, the server was made run-time configurable (yes, including
   WORLD_X and WORLD_Y) so that you didn't have to re-build an entire server
   each time you changed an option (you just have to rebuild the world
   sometimes. ;-) )

   The source is still managed by the Wolfpack team, and still headed
   up by Steve McClure.

NAME
   Merc - Changes from KSU code to Merc code

Level: Expert

There  have  been  several  changes/fixes  made to the KSU code for the Merc V
game.  This will outline the various changes and how they will affect you.

Bridges

There was a bug which allowed planes that were on bridges  that  collapsed  to
remain  in  the  sea  sector  and  could be retrieved by either rebuilding the
bridge or moving them onto a 100% highway.  This has been fixed  so  that  any
planes upon a bridgespan which falls will be destroyed.

Uncompensated Workers

Uncompensated  workers  were not paying taxes, even though the version command
provided a tax rate for them.  They now pay the taxes that are shown.

SYNTAX
   [##:##]% reject reject announcements *

This command now works, so that you can reject announcements  from  everybody.
This is not recommended though...

Technology

The tech formula has been fixed so that all increases in material result in an
increase in the amount of tech produced.

        if(breakthroughs > 0.75) {
             above = breakthroughs - 0.75;
             tech = 0.75 + log2(1 + above);
        }
        else {
             tech = breakthroughs;
        }

Grind

The grind command now requires available work to grind up bars.   It  takes  5
avail to grind up a gold bar.

Loans

Loans  have been removed from Merc V.  This is an experiment to see how things
go without loans being available.

Country Names

Certain commands only worked with country numbers,  but  they  now  work  with
country  names  as  well.  The primary command that this affects for Merc V is
report.

Production

The production of dust/oil/rads is now limited to the resource content of  the
sector.  It used to be possible to get more out of a sector.,

Starvation

Sectors  that  have  a very large number of civilians that starve will have at
most 499 civilians after the update unless there was enough food to feed  more
than 499 civs.

Attack

The attack command now uses at least 1 mobility point per sector that partici-
pates in any attack.

Pinpoint Bombing

Pinpoint bombing now lists all the commodities in a sector that can be bombed.

Production Report

The  production report now contains a report of what will actually be produced
by your sectors at the next update.  Since some of the rounding  done  by  the
update  code uses a random percentage chance, it is possible that you will get
1-2 units more of some of the items.  The production report command is conser-
vative, and assumes that all rounding will be down.

Version

The  information  in  the version command was modified so that the information
that was printed out would reflect the actual parameters of the game.

NAME
   Old-empire - Differences from 1.2 to UCB Empire

Level: Expert

          UCB Empire Version 0.9.24 - Update for Version 1.2 Players

So you want to try the New Empire Huh?

Okay,  I  have written this document with YOU in mind!  Welcome to the Univer-
sity of California at Berkeley's Empire!  (From now  on  called  UCB  Empire).
There are a whole bunch of changes in the game since we last played, so I need
to bring you up to date.

Our OLD EMPIRE game was Version 1.2 - written way back in the  70's  by  Peter
Langston, when he was going to College like we are!  But Empire has come along
way since then - and what many have considered the REAL EMPIRE was released in
1985 - containing the final version of Peter Langston's Empire game.  It still
is considered the Standard.  But in  1986  the  computer  brains  at  Berkeley
decided to play around with the Source Code and create their own enhanced ver-
sion of the game.  Hence Berkeley Empire was created....

                           Changes from Version 1.2

(Please keep in mind that these are only a FEW on the changes -  you're  going
to have to read the Manual and use the INFO command to get a REAL good idea on
what you should read up on - DON'T depend on this list to tell you  everything
you need to know)

There  is  an  announce command - this command sends a Telegram to EVERYONE in
the game - and you can make an announcement to the World.

In the OLD game - you simply dug up ORE and sent it  to  the  Shell,  Defense,
etc.   factory  to  have  it processed into something else (make guns, shells,
etc).

But in the NEW game - sectors are a lot more complex.  For one  thing  curtain
sectors  CAN'T even PRODUCE until your country has reached a given TECH level.
These sectors are currently:

Shell Factories  (need at least 20 TECH) Gun  Factories   (need  at  least  20
TECH)  Petroleum  Plants [ for Airplane Fuel ] (need at least 20 TECH) Uranium
Mines   (need at least 40 TECH)

Other sectors can produce normally, even though your TECH level  is  still  0.
Keep in mind that you CAN DESIGNATE the ABOVE sectors - but they won't produce
until you reach the desired TECH LEVEL.

Also, it takes more Materials to make 1 Unit of a finished product.  By this I
mean  that  to make approximately 1 SHELL at your shell factory, you'd have to
have: 3 Dollars (in the treasury), 2 LCM, 1 HCM, and at least 20 TECH Level.

LCM is Light Construction Materials, HCM is Heavy Construction Materials,  and
I  discussed the TECH Level problem (above).  To fully understand this concept
- please see info Products and info Sector-types.

FORTS - have been improved.  It used to be in OLD Empire that you had  to  use
the  DEFEND  command  to  say which sectors you wanted to DEFEND with the guns
from your fort.  But in the NEW Empire - your forts will  fire  on  ANY  enemy
attacker as long as the attacker is within the guns' range when the attack was
made.  Hence - no more DEFEND command.

FOOD - In the OLD Empire you didn't have to worry about it -  the  people  fed
themselves.   But in the NEW Empire - there is a new sector designation called
a for agribusiness.  These are farms that make food and you have to  transport
that  food to other sectors that don't grow food or those sectors will starve.
**NOTE** that in the FERTILITY rating in the CENSUS report - only  those  with
HIGH Fertility ratings can successfully grow food.  If the FERTILITY rating is
in the 10-30% - BE CAREFUL - they may not be able to grow enough food to  sus-
tain even themselves!  Food is also a great Commodity to SELL (hint,hint!)

WEATHER  - There ISN'T ANY!  (no more rainy days :-) Although judging from the
way Berkeley has been improving the game - it won't be long till they  do  fix
it.   Can you imagine what weather will be like if they update it like the did
the planes!  Thunderstorms, tornadoes, hurricanes, earthquakes, volcanos, etc.
BUT FOR NOW - THERE IS NO WEATHER - Atmosphere is stuck at 0 - clear days!

NEXT  UPDATE  (how  will  I know when it is supposed to Happen?) - EMPIRE will
always tell you when the NEXT UPDATE is scheduled by using  the  VERSION  com-
mand.   VERSION will also tell you how much food will grow per-update and also
things like - how much food you people eat per update - etc.

MAP CHANGES - in the OLD Empire you could move u)p, l)eft, r)ight, d)own,  etc
- but now you have to move in DIAGONALS - you'll get used to it - the world is
set up like this so the game can handle more  SECTORS  per  world.   Basically
means  that the MAP display is more condensed - and you'll be able to see more
sectors on a MAP display than ever before.

   A few new SECTOR-DESIGNATIONS have been added:

       BASICS                   INDUSTRIES                MILITARY / SCIENTIFIC
       .  sea                   d  defense plant          t  technical center
       ^  mountain              i  shell industry         f  fortress
       s  sanctuary             m  mine                   r  research lab
       /  wasteland             g  gold mine              n  nuclear plant
       -  wilderness            h  harbor                 l  library/school
       c  capital               w  warehouse              e  enlistment center
       p  park                  u  uranium mine           !  headquarters
       COMMUNICATIONS           *  airfield               FINANCIAL
       +  highway               a  agribusiness           b  bank
       )  radar installation    o  oil field
                                j  light manufacturing
       #  bridge head           k  heavy manufacturing
       =  bridge span           %  refinery

PLEASE!  Fully READ the info Sector-types

I haven't got time to go through all of them - but I will point out a  few  of
them that might be unfamiliar to you.

PARKS  -  these are special because they convince your people that they should
ENLIST and go out and fight for you!  Lots of fun - gotta have one of these to
keep the ENLISTMENT rate high.

URANIUM  MINE  -  I forgot to add this above with the other Commodities - with
the Commodities FERTILITY, OIL, GOLD, MINE - there is also  URANIUM.   Uranium
is  the  most UNCOMMON natural resource and hence those that have a deposit of
it should be careful to guard it well.  When URANIUM  is  dug  up  it  becomes
radioactive  Matter  -  you then deliver the Radioactive Matter to the Nuclear
Plant and have it converted into - you guessed it - NUKES!  Be aware, however,
that  you  must have a HIGH Tech level to make nukes - and it is going to take
you a LONG TIME to get to this point.

REFINERY SECTORS: These are where the OIL you make is turned into PETROL(-eum)
for  your  various AIRPLANE needs.  Planes run on PETROL and the refinery sec-
tors make PETROL out of OIL.  You then have to deliver the PETROL to your Air-
ports for use...

LIBRARY/SCHOOL:   Obviously  your  people  aren't very smart :-) As it is your
going to need to educated them.  Education will increase CROP yields and  also
help with TECHNOLOGY.  see info education.

                                World Updates

In  the  OLD EMPIRE - updates weren't handled in a FAIR way.  If you created a
0% FORT before you logged out of Empire - it would REMAIN a 0% FORT until  you
logged  back into Empire - and if your on a LONG weekend that could have meant
that you would be WIPED OUT!!!!

In the NEW EMPIRE - updates are handled by an independent program  called  the
Transaction  Manager.  This program runs independently of EMPIRE and runs at 4
hours intervals, updating the game constantly.  That means  that  you  enemies
will  be  updated  just as often as you ARE - and may make them think a little
more carefully about attacking you.  The CURRENT update times are:

2am, 6am, 10am, 2pm, 6pm, 10pm (In the local time zone)

NO OTHER UPDATES ARE POSSIBLE - except at these times.  What is updated is all
Mobility,  Food  Production, Shell & Factory Production, Ship Plane and Sector
Efficiency, and EVERYTHING that update used to do.  (hence there is NO  Update
Command).  Everyone is updated at the SAME TIME!

                    Other Things That Might be of Interest

Terrorists!   -  (real trouble makers, but great for setting on your enemies -
they blow up things and convert followers!)

SHOOT - it is now possible to SHOOT your civilians (captured  enemy  ones)  or
your  own  :-)  God knows why you would but...  sometimes the conquered people
are REAL radical and it DOES become necessary

SELL - you can sell your goods on the OPEN Market - and set PRICE  MULTIPLIERS
so that your enemies HAVE to buy at a BIG mark up - but your friends can still
buy your good cheap!

Okay - you've been waiting for it - so here it is!  The  new  line  of  Ships,
Planes and Nukes for Empire:

NAME
   lboard - Board enemy land unit

Level: Basic

SYNTAX
   [##:##]% lboard [] []

The  lboard  command  enables  the owner of a sector to engage in hand-to-hand
combat with a land unit in that sector.  To board unit #5 from sector 1,-1 you
might type:
   [##:##] Command: lboard 5

The  program  will ask from which sector you wish to board and how many troops
to board with.

In order to board a land unit from a sector, the land unit must be in the sec-
tor, and the sector must have mobility.

Some things to note:

Any  land units in the combat will fight as if they were simply mil, i.e. they
won't get any offensive of defensive multiplier,  except  for  "marine"  units
which get their full bonus.  Similarly, units on land units don't have to take
morale checks, as they are fighting as mil.  Mil on the victim unit will still
die before units take casualties, however.

Note  that you can only board with as many mil that the unit you are trying to
board can hold.

See info Attack for the exact procedure.

NAME
   pboard - Board enemy plane

Level: Basic

SYNTAX
   [##:##]% pboard []

The pboard command enables the owner of a sector to capture any planes another
player has trapped in that sector.  To board plane #6 you might type:
   [##:##] Command: pboard 6

In order to board a plane, the plane must be on the ground in  a  sector  that
you own.

Some things to note:

The  crew  of  the plane will attempt to blow up or disable the plane to avoid
capture.

The boarding parties do not recognize relations.  Thus "pboard *"  will  board
all planes in your territory whether owned by allies or enemies.

NAME
   sabotage - Damage enemy territory with spy unit

Level: Basic

SYNTAX
   [##:##]% sabotage 

The  sabotage  command  is  used to blow up commodities and cause havoc in the
sector the spy is in.  Spies don't check relations and  can  cause  damage  to
enemies  and  allies.   Sabotage  can only be done by spy units.  The spy must
have a shell to make an attempt.

Terrorizing your neighbors is dangerous work.  Spies can be caught or die dur-
ing a sabotage attempt.

Sabotage  can be more effective against enemy warehouses filled with explosive
or flammable materials.

.SH DESCRIPTION
.I fairland
is a program which creates land and ore for Empire.  It
should be run after 
.I files 
has been run and before 
.I emp_server
has been started.  This is a land generator for empire that creates a
specified number of continents, and spaces them evenly accross the
map.  It tries to make all of them the same size, and makes sure that
they don't meet.  It gives each start island exactly the same
distribution of resources and the same number of mountains.  You can
get nearly any kind of map you want by choosing the right arguments.

.SH DESCRIPTION
.I pconfig
creates an "econfig" file which may be used with the \-e argument with
most Empire programs.  By default, Empire programs look for a file
called "econfig" in the data directory, but the 
.I pconfig
program may be used to create an alternate Empire configuration file.
After you have created an "econfig" file, you can edit the game
configuration data in the file which the server uses to control
various parameters for the game.

# postresults - Steve McClure (ionica@empire.cx), 1998
#    Do an automated post to rec.games.empire of a game's power chart
#    and the last day's annoucements.
#
# To use, you need to create a visitor country in your game.  For example,
# use "News" and "reporter" for the country name/rep of a special country
# used to get the power chart and annos.
#
# Also, this file references a "visitor" account.  If you don't have one,
# you may want to take that line out.
#
# Note that this uses 'inews' to post.  It's also very crude.  But, it
# works great when used from a cronjob.
#
# You will also want to change the messages below to more accurately 
# reflect your game.
#
# Note this is the same script I used to post results for the Winterfest
# '98 Tourney.  I'm submitting it to wolfpack for inclusion with the
# server.

submitted by various people for doing routine maintainence on the
server, such as keeping it alive, making maps, posting to newsgroups,
starting blitzes, etc.

While we provide these files for your convenience, they are not an
"official" part of the server.  Therefore, you can e-mail us with
problems with them, but we may or may not know the answers and/or how
to fix any problems.  Some of the files have the author's e-mail in
them, and others are anonymous submissions, so you may want to try
to contact the authors if all else fails (but try us first, as we might
know.)

Wolfpack!

------

keepitup
	Automatically reboots your Empire server if it crashes.
	No configuration necessary.  See the comments at the top of
	the file for syntax.  See crontab.config for an example of
	what to add to your crontab.

saveass
	Makes automatic backups of your game data.  See crontab.config.
	To configure, change two paths at the top of the file.

bigstart
	Handy for blitzes.  Fill start islands with sanctuaries and
	fill the sanctuaries with civs.  To configure, change the
	value of "height" and "width" in teh BEGIN routine.

postresults
	Useful for posting canned results to a newsgroup.

blitz/
	Scripts for running an auto-resetting blitz.

mapper/
	Scripts for making mpeg videos of your game.  See mapper/README
	for configuration details.

#! of the first empire tourney in December of 1990.  This is a basic script
#! run from cron usually 15 miniutes before the update and keeps three copies

   This directory contains a number of scripts which output PPM format
files suitable for conversion to gif with the PBM utilities or MPEG
with mpeg_encode.  mpeg_encode is available from
	http://s2k-ftp.cs.berkeley.edu:8000/multimedia/mpeg/
PBMPLUS is available from 
	ftp://ftp.ee.lbl.gov/
Some of the scripts (mapper in particular) depend on a country
"mapper" being defined that can be logged into automatically using the
Empire client eif.  Modify to use the client and country name of your
choice.

pgmmap.awk
   A simple map making program.  Reads a deity dump file and produces
a grayscale .pgm file as output, with each color corresponding to a
country number.  To make a color coded map, scramble the colors.

pgmfallout.awk
   Convert a deity census file into a PGM file with fallout levels.

randppm.awk
   Generates random colors in a ppm file.  Useful for remmapping colors
from pgmmap.awk

over.awk
   Reads in a report file and generates a text overlay of country names.
Requires pbmtext (part of netpbm) to work.

param.pl
   Modify an mpeg parameter file to use map-*.gif files as input.
Reads the highest level file from the file 'frames' and skips over any
file not 300-500 bytes long (in a 64x32 blitz, the .gif files should
be ~400 bytes).  Larger worlds may require different size limits.
Disabling the size limits is not advised, as this is the only way
corrupt frames are eliminated.

makempeg
   Log into the mapper country, capture new report files, and generate
a new .mpg file.  Also copies map.mpg and final.gif into the web space
directories so others can view them.  The web copy may be commented
out or modified to meet your local needs.

mapper
   Log into mapper country and capture a map of the current owners of
the world (.gif format).  Games without fallout should comment out the
fallmap producing line.

archive.pl
   Pushes the archived blitz records down the stack (in web space) and
prints out a new .html index.

.SH DESCRIPTION
.I empire
is a bare bones client to connect to the Empire server.  Empire is a
global economic/political/military simulation game wherein players,
representing national governments, make "real-time" decisions
concerning resource allocation, national goals, international
diplomatic efforts, etc.  Extensive records are kept for all players.

WARNING -- This game is not only addictive but often peels back
the thin veneer of civilization that hides the maniac within.
.SH OPTIONS
.TP
.IR country
the name of your country in the game
.TP
.IR password
the password for your country in the game
.TP
.BI \-k
if someone else is connected to your country, kill their connection
.TP
.BI \-2 outfile
redirect output to 
.I outfile
.SH ENVIRONMENT VARIABLES
setenv EMPIREHOST server-machine to access the game on server-machine.
.PP
setenv EMPIREPORT port-number to access the game on port-number.
(the person running the game should tell you what this is... if not, 
you should have the right default already.)

This is the basic Empire Client version 2.8.

See the "LEGAL", "LICENSE", "CREDITS" and "README" files for all the
related information and legal notices. It is expected that any future
projects/authors will amend these files as needed.

For questions and comments, please contact "wolfpack@empire.cx".

Note that this client is the same client that is shipped with the
server.  The only difference is the Makefile is copied from the
"Makefile.standalone" for the standalone distributions, and
from the "Makefile.server" for the server distributions.

If you are building this with the server, it is built automatically.

If you are building this standalone, continue reading to see how
to build the client.

To make the program, edit ipglob.c and change empirehost[] to
point at the machine where the game is running (although this is
not necessary.)

Also, if you are going to use "gcc", you need to change the Makefile
line "CC=cc" to "CC=gcc".

To build for a Linux macihne, type "make linux".

To build for a HP/UX machine, type "make hpux".

To build for a DG/UX machine, type "make dgux".

To build for a Solaris machine, type "make solaris".

To build for a Windows machine, type "nmake win32".
  (Note that the Windows port was built with MSVC 5.0)

For other machines, type "make".

You can change hosts on-the-fly by using environment variables -- see
the man page for details.  But, for a short version, you can set the
EMPIREHOST and EMPIREPORT environment variables to the host and
port of the server you wish to connect to, and the client will
automatically use them instead of the built in ones.

Also note that pipes do not work on the Windows versions.

This library implements a reasonably general version of the A* algorithm.
Basically, A* is like an ordered search, but with a heuristic that allows
it to make a better choices as to which path to take.  The subdirectory
"test" has example code for using A* to search a weighted cartesian matrix.
The file "XXX//bestpath.c" has code to interface Empire to the A*
algorithms.

This library is copyrighted; see the file COPYRIGHT for details.

COMPILATION

Do a "make" in this directory to make the library.  Cd into "test" and
do a "make" there to make a test program, called (ta da) "test".

LIBRARY USAGE

Pretty much all the data that the user needs to communicate to the library
is stored in an "as_data" structure, which is created by a call to "as_init":

	struct as_data	*adp;

	adp = as_init( ... );

The arguments to as_init specify a number of key things the algorithm will
use, and these are discussed below.

Once you have an "as_data" structure, you can fill in its "from" and "to"
members, which specify the coordinates of the points between which you want
to go.  The basic coordinate data structure is the "as_coord", which is
just an "x" integer and a "y" integer.  So:

	adp->from.x = ...;
	adp->from.y = ...;
	adp->to.x = ...;
	adp->to.y = ...;

and then call as_search:

	as_search(adp);

If the return value of as_search is 0, the algorithm found a path from
"from" to "to".  The path is stored in the "path" member of the "as_data"
structure, and is just a linked list of coordinates ("as_coord" structs)
from "from" to "to".

If the return value of as_search is -1, the algorithm couldn't find a
path from "from" to "to".  If the return is -2, a system error occurred
(most probably malloc failed).

After a call to as_search, lots of malloced data 'n' stuff will be
floating around, all pointed to by items in the "as_data" data structure.
If you call "as_search" again (presumably with new "from" and "to"
coordinates), the system will free these data structures and reallocate
new ones.  If you no longer want the data structures at all (i.e., you
never intend to call "as_search" again), you can call:

	as_delete(adp);

and this will free up all data associated with the as_data structure pointed
to by adp.

ARGUMENTS TO AS_INIT

"as_init" takes eight arguments, in the following order:

	maxneighbors		The maximum number of neighboring sectors a
				coordinate can have.  On a cartesian grid,
				this would be 8.  On a hex map, it would be 6.

	hashsize		The size of the hash table used to determine
				if we've visited a particular coordinate.

	hashfunc		A pointer to a function that takes an
				"as_coord" as an argument and returns an
				integer that will be used as a hash value.
				If this is a NULL pointer, the as library
				will assign its own hash function that just
				adds the x and y coordinates together.

	neighborfunc		A pointer to a function that takes a coordinate
				(call it "c"), a pointer to an array of
				coordinates of length "maxneighbors", and
				a user data pointer (see below).  This
				function should figure out the coordinates
				of all the neighbors of "c" and put them in
				the array cp[0] ... cp[maxneighbors-1].
				It should then return the number of neighbors
				found.

	lbcostfunc		A pointer to a function that takes two
				coordinates, call them "from" and "to",
				and a user data pointer (see below).  It
				returns a double precision *LOWER BOUND*
				on the cost to get from "from" to "to".
				"from" and "to" may be separated by an
				arbitrary distance.  More on this below.

	realcostfunc		A pointer to a function that takes two
				coordinates, call them "from" and "to",
				and a user data pointer (see below).  It
				returns a double precision value of
				the *actual cost* to move from "from" to
				"to".  Note that "from" will never be more
				than one sector away from "to".

	seccostfunc		A pointer to a function that takes two
				coordinates, call them "from" and "to",
				and a user data pointer (see below).  It
				returns a double precision value that will
				be used to break ties when two nodes have
				the same lower bound to the target.  An
				example will be discussed below.

	userdata		A (char *) that can be a pointer to
				any kind of data you want.  This will
				be passed as the third argument to the
				neighborfunc, lbcostfunc, realcostfunc,
				and seccostfunc.

Look in test/cart.c to see examples of these functions for cartesian
coordinates.

NOTES ON THE LOWER BOUND FUNCTION

"lbcostfunc" is *CRUCIAL* to the algorithm's performance.  The entire
idea behind the A* algorithm is that, when considering whether to move
to a new coordinate, you know two things:

	(1) how much it's cost you to get to that coordinate so far,

	(2) a LOWER BOUND on how much it will cost to get to the
	    destination from that coordinate.

If these two conditions are met, the algorithm will return the optimal
path to the destination.  The closer the lower bound is to the actual
cost to get from one point to another, the quicker the algorithm will
find this path.  HOWEVER, if the lower bound is ever violated, i.e.,
if the so-called lower bound function returns a value that is greater
than the actual cost to get to the destination, then the algorithm will
not necessarily find the optimal path.

Example:

Assume that we're on a cartesian matrix, and the cost to move from one point
to another is just the distance between the two points, and that no
other costs are involved.  In this case, the lower bound function could
be the same as the actual cost function, i.e.,

	real cost = lower bound cost = sqrt(dx^2 + dy^2);

In this case, the algorithm will find the destination as quickly as possible.

Another example:

Again assume we're on a cartesian matrix, and the cost to move from
one point to another is two things: (1) the distance between them, (2) some
arbitrary cost function we get off of a map.  E.g.,

		X

	   0  1  2  3
	0  0  0  0  0
	1  0  0  0  0 
   Y	2  0  0  2  0
	3  0  0  0  0

The real cost to move from (x,y) 0,0 to 1,0 is 1.  That is, it's the distance
(1) plus the value of the map at (1,0), which is 0.  The real cost to move
from (1,2) to (2,2) is 3: the distance (1) plus the map value at (2,2), which
is 2, totaling 3.

In this case, the lower bound function could still be the distance between
the two points, since this WILL NEVER BE MORE than the actual cost, and
hence is a lower bound.  I.e.,

	real cost = sqrt(dx^2 + dy^2) + map costs

	lower bound cost = sqrt(dx^2 + dy^2)

	lower bound cost <= real cost for all coordinates

This is what the the example in the "test" directory uses.

A third example:

You could make the lower bound function always return 0.  This would be
a valid lower bound of the cost to move between any two points.  In this
case, the A* algorithm will behave like a breadth-first search, and isn't
very much fun.

SECONDARY COST FUNCTION

The algorithm tries new coordinates in order of lowest lower-bound.
There can be cases where the lower-bound function for two (or more)
coordinates is the same, i.e., there is a tie.  The algorithm uses
the secondary cost function (which does NOT have to be a lower bound)
to choose which coordinate to pick.  A typical heuristic might be
to use Euclidian distance for this secondary cost function, on the
assumption that it's always better to move closer the destination.
The Empire code does just this.

If you don't need a secondary cost function, just specify a NULL pointer
to the seccost argument to as_init, and the routines will use 0.0 for you.

EMPIRE INTERFACE

The interface code in "XXX/bestpath.c" is a rather complicated example
of A* interface code.  What it does is based on some features of Empire
that are explained here.

First, movement cost in Empire is based on a quantity called "mobility
cost", which is a property of every sector.  As we trace a path from
source to destination, we add up mobility cost as we go.  Once we're
there, we have a total mobility cost.  This is what we'd like to
minimize.

Second, Empire has highways, which are zero cost movement paths.  This
hurts the A* algorithm, because it means that the lower bound cost
function is very weak.  For example, think what happens if we move from
one side of the country to another: if the two sectors are attached via
a highway, the cost will be very small -- in fact, it will be the cost
to move out of the source sector, and the cost to move into the
destination sector.  If, on the other hand, the two sectors aren't
connected by a highway, the cost could be quite large.  Thus, the lower
bound is just the cost to move out of a sector plus the cost to move
into a sector.  This is a pretty weak lower bound, and means that we
have to explore a lot of sectors.

Third, the mobility costs tend to tie a lot, as explained in the
section above on secondary cost functions.  Thus, we use the Empire
"mapdist" function as a secondary sort function to break ties.  For
example, consider the case where a sector borders two highway sectors,
one on each side.  The lower bound function will say that the two have
equal lower bound costs, since they're both highways and cost nothing
to move on.  The secondary sort function is then used to break the tie --
it says, "Take the one that moves you closer to the destination".

Fourth, all of the information we need about a sector (its mobility
cost, who owns it, etc.) is stored in the sector file on disk.  This 
means that the getsect() function to get it off disk will do a read(),
which is VERY expensive.  Because of the weak lower bound, A* ends up
checking lots of sectors, including sectors that it's seen before.
To avoid doing thousands of system calls per second, the bestpath.c file
has sector caching routines that store in memory copies of every
sector we read.  (The function bp_getsect handles this).  This means
we never read a sector from disk more than once, although at the expense
of using lots of memory.

THEORY OF OPERATION

The basic idea is as follows:

	1. Add the start node to the head of a master queue.
	2. Is the head of the queue where we want to be?  If so, stop.
	3. Make a list of all the neighbors coordinates around the
	   coordinate of the head.

	4. For each neighbor coordinate,

		Compute the lower bound cost to the destination from here.

		If this coordinate is already on the either the
		master queue or the "tried" queue:

		4a.	If it was on either the "master" queue or the
			"tried" queue and the one on the queue has a
			smaller lower-bound than the neighbor, ignore
			this neighbor and go on to the next neighbor.

		4b.	If it was on the "master" queue and the new
			neighbor has a smaller lower bound,
				Move the one on the queue to a different
				queue called "subsumed".

		4c.	If it was on the "tried" queue and the new
			neighbor has a smaller lower bound,
				Move the one on the "tried" queue to the
				master queue, and update its lower bound
				value to be as the new neighbor, and
				update its backpointer appropriately.

	   We now have a list of all neighbor coordinates that are either
	   not on the queue already, or are cheaper than the ones on the
	   queue.

	5. Move the node at the head of the queue (the one whose neighbors
	   we now have in a list) onto a different queue called "tried".

	6. Sort this list of neighbors, and merge it into the master queue,
	   keeping the master queue ordered by lower bound cost to destination.

	7. Goto 2.

My algorithm does all of this, plus a little more (the above doesn't really
mention backpointers except in passing), EXCEPT: I don't do step 4c.
I'm not convinced that this can ever occur if the lower bound rule isn't
broken, and I have yet to see it occur.  However, if as_winnow returns -1,
this error has occurred.

**  bestpath(x1,y1,x2,y2,(s_char *)terrain);
**
**  Calculate routing string to get from sector [x1,y1] to sector [x2,y2]
**  via a specified type of terrain.
**
**  Specify:
**
**	x1,y1	     starting coordinates
**
**	x2,y2	     destination coordinates
**
**	terrain	     ptr to string showing the types of sectors that
**		     we're allowed to pass through:
**
**		     A null string enables routing through any kind of
**		     sector (useful for airplanes).
**
**		     A string that begins with an 'R' ensures that
**		     the source and destination sectors also match
**		     the specified type of terrain.
**
**		     A string that begins with a '~' (after the 'R',
**		     if necessary) specifies that we can pass through
**		     any kind of sector EXCEPT those in the remainder
**                   of the string.
**
**		     Examples:
**
**			"R~.^"	all sectors along route must be
**				non-ocean, non-mountain
**
**			"+"	all sectors between start and end
**				must be highway
**
**			"h. "	all sectors along route must be
**				harbor, water, or unmapped
**
**  'bestpath' returns a pointer to a route string containing either:
**
**     yugjbn - string of normal routing characters if route possible
**     ?      - if route is longer than MAXROUTE characters
**     \0     - (null string) if no route possible
**     h      - if start and end points are the same sector

/* This code implements the vsprintf function, without relying on
 * the existance of _doprint or other system specific code.
 *
 * Define NOVOID if void * is not a supported type.
 *
 * Two compile options are available for efficency:
 *	INTSPRINTF	should be defined if sprintf is int and returns
 *			the number of chacters formated.
 *	LONGINT		should be defined if sizeof(long) == sizeof(int)
 *
 *	They only make the code smaller and faster, they need not be
 *	defined.
 *
 * UNSIGNEDSPECIAL should be defined if unsigned is treated differently
 * than int in argument passing.  If this is definded, and LONGINT is not,
 * the compiler must support the type unsingned long.
 *
 * Most quirks and bugs of the available sprintf fuction are duplicated,
 * however * in the width and precision fields will work correctly
 * even if sprintf does not support this, as will the n format.
 *
 * Bad format strings, or those with very long width and precision
 * fields (including expanded * fields) will cause undesired results.

\title{The {\sc Rex} lightweight process library}
\author{Stephen Crane\\ (jsc@doc.ic.ac.uk)\thanks{Thanks to Mark Little
(m.c.little@ncl.ac.uk) for the Linux port}}
\begin{document}
\maketitle
This document describes the interface to and the behaviour underlying
my threads library for Rex.\footnote{Available as lwp.tar.gz by anonymous 
ftp from gummo.doc.ic.ac.uk:/rex.  Rex (Esprit project 2080) was
axed by Men in Suits.}  It has been tested on Sun-3, Sun-4,
Mips, 386-BSD and Linux systems.  Counting semi-colons, it is 
260 lines long, including support for the different architectures (this
figure includes variable- but not function-declarations).

\section{Threads}
Threads are prioritised and
non-preemptive.  Operations supported on threads are:
\begin{tgrind}
\L{\LB{}\Tab{8}{\K{struct} pcb *initlp (\K{int} priority)}}
\L{\LB{}\Tab{8}{\K{struct} pcb *creatp (priority, entry, size, argc, argv, envp)}}
\L{\LB{}\Tab{8}{\K{void} readyp (\K{struct} pcb *p)}}
\L{\LB{}\Tab{8}{\K{void} yieldp (\K{void})}}
\L{\LB{}\Tab{8}{\K{void} *getenvp (\K{struct} pcb *p)}}
\L{\LB{}\Tab{8}{\K{void} setenvp (\K{struct} pcb *p, \K{void} *)}}
\L{\LB{}\Tab{8}{\K{void} suicidep (\K{void})}}
\L{\LB{}\Tab{8}{\K{void} destroyp (\K{struct} pcb *p)}}
\end{tgrind}
\begin{description}
\item[initlp] initialises the threads runtime, creating a thread with
specified priority for the invoker.
\item[creatp] creates a new thread with specified {\em priority}, {\em
entry} point, with a stack of {\em size}, {\em argc} arguments in {\em
argv} and a user-defined environment pointer.
\item[getenvp] returns the environment pointer associated with the given
thread.  If the thread is null, the current thread is assumed.
\item[setenvp] reassigns the environment pointer associated with the
given thread.
\item[readyp] makes the specified thread ready to run, or the current
thread if null.
\item[yieldp] makes the current thread ready to run.  If no thread of 
higher priority is runnable, the current thread will run.
\item[suicidep] marks the invoking thread as dead.  It will never be
rescheduled.
\item[destroyp] marks the specified thread as dead.  It will be removed
at the next reschedule.  If it is currently running, it will be
unaffected until the next reschedule.
\end{description}

\section{Semaphores}
For synchronisation, counting semaphores are provided.  Available
operations are:
\begin{tgrind}
\L{\LB{}\Tab{8}{\K{struct} sem *creats (\K{int} count)}}
\L{\LB{}\Tab{8}{\K{void} signals (\K{struct} sem *s)}}
\L{\LB{}\Tab{8}{\K{void} waits (\K{struct} sem *s)}}
\end{tgrind}
\begin{description}
\item[creats] allocates a new semaphore from the heap and initialises its
count.
\item[signals] increments the semaphore's count, makes a waiting process
ready if there is one.  If the readied process's priority is greater than
that of the signaller, a reschedule is done.
\item[waits] decrements the semaphore's count.  If it becomes negative,
the current process is suspended and a reschedule is done.
\end{description}

\section{Signals}
The library is concerned with two types of signal, {\sc sigio} and {\sc
sigalrm}.  These signals are normally blocked until the null process is
scheduled.  It uses {\tt sigpause()} to reenable them and wait for one
to arrive.  While awaiting a signal, the null process `runs' at maximum
priority.  Thus users will not be able to cause a reschedule from
their handlers.  When {\tt sigpause()} returns, the signal will have
been handled and the null process drops back down to the lowest priority
and yields to any thread which has been made ready to run from the
user-level handler.

These semantics make the library rather unresponsive to signals in the
presence of busy processes.  If a more responsive system is required,
the constant {\sc LCOUNT} may be changed.  This value determines the
number of times the {\tt reschedp ()} function must be called before
signals are re-enabled.  If given a value of {\tt 1}, it will affect
context-switching time by about 50\%.  Its default value is {\tt -1}.

\subsection{Input and output}
Input and output present a problem to threads, because they require
calls to the underlying {\sc Unix} system, which will block not only
the invoking thread, but also all others in the process.  Thus, in
general, a thread must wait until the descriptor on which I/O is to
be done becomes ready for the operation.  This is done by trapping
{\sc sigio}.  Two routines are provided:
\begin{tgrind}
\L{\LB{}\Tab{8}{\K{int} sigioset (\K{int} fd, \K{void} (*han) (\K{void}
*, \K{int}), \K{void} *ctx)}}
\L{\LB{}\Tab{8}{\K{int} sigioclr (\K{int} fd)}}
\end{tgrind}
The general model adopted for processing {\sc sigio} is to install a
{\em handler} routine for the I/O descriptor using {\em sigioset} and
remove it using {\em sigioclr}.  The user is responsible for setting up
the device correctly to generate {\sc sigio}.  When {\sc sigio} arrives
for the descriptor, the handler will be called with a context pointer
as its argument.  (In C++, this context is the instance pointer of the
invoking thread.)

\subsection{The timer}
A single routine is provided to block the invoking thread for the
specified time:
\begin{tgrind}
\L{\LB{}\Tab{8}{\K{void} delayp (\K{int} n)}}
\end{tgrind}
This routine blocks the invoker for {\em at least\/} the time specified.
If this is zero, a reschedule is done.  Delays are implemented as a
delta queue, using {\sc sigalrm}.  $n$ specifies a microsecond delay
which is of limited utility in practice.

\begin{description}
\item[sun3] has very lightweight process initialisation, compared with
context switching.
\item[sun4] has a high context switch time as a result of {\tt setjmp ()} and
{\tt longjmp ()} implementations.  Process initialisation is also relatively
heavyweight: it requires two calls to {\tt setjmp ()} and one to {\tt longjmp
()}.
\item[mips] provides its own context switching in assembly language.
\end{description}

\section{Porting to another architecture}
Although the threads library is quite portable, a few guidelines should
be observed when moving to a new architecture.

\begin{itemize}
\item Create two new files for your architecture/kernel (e.g. {\tt sun4.c}
and {\tt sun4.h}). 
The `.c' file should contain any routines which your version of {\sc Unix} is
missing and a thread initialisation routine:
\begin{tgrind}
\L{\LB{}\Tab{8}{\K{void} initp (\K{struct} pcb *, \K{void} *)}}
\end{tgrind}
The `.h' file contains any machine-specific definitions.
\item If {\tt setjmp ()} and {\tt longjmp ()} don't work on your machine
(for example the {\sc Ultrix} {\tt longjmp ()} implementation checks that
the frame being jumped to is an ancestor of the current one), you will
have to write {\tt savep ()} and {\tt restorep ()} and put the following
define into your machine-specific header file:
\begin{tgrind}
\L{\LB{}\Tab{8}{\K{\#define} OWN\_CONTEXT\_SWITCH}}
\end{tgrind}
\item Compile and run the three test programs: {\tt producer.c}, {\tt
timer.c} and {\tt bm.c}.
\item Add the name of the architecture to `config'.
\item Send {\tt new-arch.[ch]}, any context diffs for the rest of the
library and the output of {\tt bm.c} to {\tt jsc@doc.ic.ac.uk}.  Also
please let me know where you got the library from.
\end{itemize}

/*
 * The principal object in this code is the "combat" object.  A combat object
 * is either a sector or ship.  There are
 * usually two instances of this, the "def" or defense combat object, and
 * the array of "off" or offense objects.  The number of offense objects is
 * determined by the value of off->last (e.g. more than one attacking sector).
 * the type of the object is determined by combat->type which can take the
 * values EF_SECTOR, EF_SHIP, EF_PLANE, or EF_BAD.  Another important parameter
 * which is often passed to these functions is combat_mode.  This can take
 * the value A_DEFENSE, A_ATTACK, A_ASSAULT, A_PARA, A_BOARD and A_LBOARD.
 * As these six modes of being in combat affect things like mobcost and combat
 * value, there are often switches made on combat_mode.  Note that in all cases
 * no mobility is taken from sectors, ships, or land units until the player
 * has committed to a fight.  Instead, the cost is temporarily placed in
 * combat->mobcost, or llp->mobil as the case may be, and then when the object
 * is "put" back onto disk, then the amounts in these variables are subtracted
 * from the object's mobility.  It needs to be done this way as the objects
 * are constantly being re-read from disk, and we don't want to take any mob
 * unless a fight actually occurrs.

 * In the oceans, it puts oil = (2d6-4)*10+d10, fert = (2d6-2)*10+d10
 *                        (max of 127 in both cases)
 *
 * For islands smaller than ISLANDSIZE, it puts in normal
 *     resources. (These are assumed to be small non-start islands)
 * For islands at least ISLANDSIZE big, it makes normal fert,
 *     but it uses the MIN, OIL, GOLD, and URAN arrays to find out
 *     what resources to put there. The intent is to find all start
 *     islands, and give them all a pre-determined spread of stuff.
 *     To change the stuff, just change the MIN, OIL, GOLD, and URAN arrays.
 *
 * For example, if the GOLD array is 90,80,70,60, it'll try to put 1
 *     sector with 90 gold, 1 with 80 gold, 1 with 70, and 1 with 60 gold
 *     on each island of at least ISLANDSIZE. It will not overrun start
 *     sectors, and should be run AFTER you have placed capitals.
