===================
Freeciv Version 2.1
===================

Welcome to Freeciv!

This archive contains Freeciv, a free Civilization-like game, primarily
for X under Unix.  It has support for multiplayer games locally or
over a network, and an AI which gives most people a run for their money.

Freeciv aims to be mostly rule-compatible with Civilization II [tm],
published by Sid Meier and Microprose [tm].  A few rules are different
where we think it makes more sense, and we have lots and lots of
adjustable parameters to make customizing games possible.

Freeciv has been implemented completely independently of Civilization;
you do not need to own Civilization to play Freeciv.

Compiling and installing:
=========================

Please read the INSTALL file carefully for instructions on how to get
Freeciv compiled and installed on your machine.


Starting a new game:
====================

Freeciv is actually two programs, a server and a client.  When a game
is in progress, there will be one server program running, and as many
client programs as there are human players.  The server does not need
X, but the clients do.

  NOTE:
  The following examples assume that Freeciv has been installed on
  your system, and that the directory containing the "civclient"
  and "civserver" programs is in your PATH.  If Freeciv is not
  installed, then you may want to use the "civ" and "ser" programs,
  which can be found in the top Freeciv directory.  They are used
  in exactly the same fashion as "civclient" and "civserver".

Running Freeciv involves starting the server, then the client(s)
and AI(s), then telling the server to start the game.  Here are the
steps:

Server:

  To start the server:

  |  % civserver

  Or for a list of command-line options:

  |  % civserver --help

  Once the server is started, a prompt will appear:

  |  For introductory help, type 'help'.
  |  >

  and, you can see this information by using the help command:

  |  > help
  |  Welcome - this is the introductory help text for the Freeciv server.
  |
  |  Two important server concepts are Commands and Options.
  |  Commands, such as 'help', are used to interact with the server.
  |  Some commands take one or more parameters, separated by spaces.
  |  In many cases commands and command arguments may be abbreviated.
  |  Options are settings which control the server as it is running.
  |
  |  To find out how to get more information about commands and options,
  |  use 'help help'.
  |
  |  For the impatient, the main commands to get going are:
  |    show   -  to see current options
  |    set    -  to set options
  |    start  -  to start the game once players have connected
  |    save   -  to save the current game
  |    quit   -  to exit
  |  >

  If you like, you can use the 'set' command to set any of the various
  server options for the game.  You can get a list of the options
  with the 'show' command, and detailed descriptions of each with the
  'help <option-name>' command.

  For example:

  | > help size
  |  Option: size  -  Map size in 1,000 tiles units
  |  Description:
  |    This value is used to determine the map dimensions.
  |      size = 4 is a normal map of 4,000 tiles (default)
  |      size = 20 is a huge map of 20,000 tiles
  | Status: changeable
  | Value: 4, Minimum: 1, Default: 4, Maximum: 29

  And:

  |  > set size 8

  This will make the map twice as large as the default.

Client:

  Now all the human players should join, by running the Freeciv
  client:

  |  % civclient

  This assumes the server is running on the same machine.  If not, you
  can either specify it on the command line with the '--server' option,
  or enter it into the first dialog box once the client starts.

  For example, suppose the server is running on a different machine
  called 'neptune'.  Then players would join with a command like:

  |  % civclient --server neptune

  If you're the only human player, then only one client needs to be
  started.  In standard Unix fashion you can start the client
  "in the background" by appending an ampersand:

  |  % civclient &

  Another option for the client you may like to try is the '--tiles'
  option, which can be used to select different "tilesets" (that is,
  different graphics for the map terrain, units, and so on).  The
  distribution comes with 5 main tilesets:
  - amplio: An isometric tileset with larger and more detailed tiles.
  - isotrident: An isometric tileset similar in shape to the one in Civ 2.
  - trident: a Civ 1-style tileset with 30x30 tiles.
  - isophex: an isometric hexagonal tileset
  - hex2t: an overhead hexagonal tileset

  In this release the amplio tileset is the default tileset.
  To try another one, for instance the trident tileset, start the
  client with:

  |  % civclient --tiles trident

  Other tilesets are available from http://www.freeciv.org/wiki/Tilesets


  Clients can be authorized to issue server commands.  To allow them
  to use informational commands only, type at the server prompt

  |  > cmdlevel info

  Clients can now use '/help', '/list', '/show settlers', etc.

Computer Players:

  There are two ways to create AI players.  The first is to set
  the number of players (human and AI) by setting the 'aifill'
  server option.  For example:

  |  > set aifill 7

  After using the 'start' server command to start the game, any players
  which aren't controlled by humans will be AI players.  For the above,
  if two human players had joined, 5 AI players would be created.

  The second way is to explicitly create an AI with the 'create'
  server command.  For example:

  |  > create HumanKiller

  This will create an AI-controlled player called HumanKiller.

  AI players are assigned to nations after all human players have
  chosen their nations, but you can choose a particular nation for an
  AI player by using the normal name for that nation's leader.  For
  example, to play against AI-controlled Romans, use this server
  command:

  |  > create Caesar

  Note, this is just a preference:  If no other human player chooses
  to play the Romans, then this AI will.

Server:

  When everybody has joined (use the "list" command to see who's in),
  start the game with the "start" command:

  |  > start

And the game is on!

  NOTE: In this version of Freeciv, the GTK and SDL clients have the
  capability to automagically start a civserver session when the user
  selects "Start New Game" from the main menu. This reduces the steps
  needed to get started playing a game of Freeciv. On the other hand,
  it also means that if the client crashes for some reason or becomes
  unavailable, the civserver session will also be lost. So starting a
  separate civserver session and then connect to it with the client is
  generally the recommended method.


Announcing the game:
====================

If you do not want to limit your opponents to local friends or AI players,
visit the Freeciv metaserver:

  http://meta.freeciv.org/metaserver.phtml

It is a list of Freeciv servers.  To make your own server announce itself
there, start civserver with the '--meta' option, or just '-m' for short.

Caveats:

 1) Due to the inclusion of new features, different client and server
    versions are often incompatible. The 2.0.0 version is for example
    incompatible with 1.14.2 or earlier versions.

 2) If the Metaserver button in the connection dialog doesn't work,
    check if your ISP uses a mandatory WWW proxy and make civclient
    use it through the $http_proxy environment variable.  For instance,
    if the proxy is proxy.myisp.com port 8888, set $http_proxy
    to http://proxy.myisp.com:8888/ before starting the client.

 3) Sometimes there are no games on the metaserver.  That happens.
    The number of players there vary with the time of the day. Try 
    starting one yourself!


Playing the game:
=================

The game may be saved at any time using the 'save' server command,
like so:

  |  > save mygame.sav

(If your server is compiled with compression support, and the
'compress' server option is set to other than 0 (zero), then the
file written may be compressed and called 'mygame.sav.gz'.)

The Freeciv client works pretty much as you would expect from a
multiplayer civilization game.  That is, the human players all move
at the same time, then all the AI players move when all the human
players have completed their turn.  There's a turn timeout value,
which is by default set to 0 seconds (no timeout).  The server
operator can alter this value at any time with the 'set' command.

Have a look at the online help system. All three mouse-buttons are
used, and documented in the help.

Players can hold down 'Shift' and push the 'Return' key to announce
the end of their turn, or just push the 'Turn Done' button.

Use the 'Players' dialog to see who has announced their end of turn,
and who you're waiting for.  (Hey feller, are you asleep or what?? ;).

Use the input line at the bottom of the window for broadcasting
messages to other players.

You can send a message to an individual player (e.g., 'peter') like so:

  |  peter: move that armor away *NOW*!

The server is smart enough to perform "name completion", so if you had
typed "pet:", it will find a player name that matches the part of the
name you typed.

You can send a message to all your allies by prefixing it with the 
letter '.' (yes, that is a period).

You can issue server commands from the client input line:

  |  /list
  |  /set settlers 4
  |  /save mygame.sav

The server operator will probably let you issue informational commands
only.  This is partly because allowing clients to use all server
commands has security implications; consider if a player tried:

  |  /save /etc/passwd

Of course the server should not be running with superuser privileges in
any case, to reduce this sort of risk.

If you're just starting, and would like to get an idea of a strategy,
have a look in the Freeciv playing HOWTO, contained in the HOWTOPLAY
file.

For lots more information about the client, the server, and the
concepts and rules of the game, see the Freeciv manual, available
at the wiki:

  http://www.freeciv.org/wiki/Manual


Ending the game:
================

There are four ways in which a game can end:

1) Only one nation or one team is left, or all other players of all
   other teams have ceded the game (/surrender).
2) The final year is reached.
3) A player builds and launches a spaceship, which reaches Alpha
   Centauri first.
4) The server operator uses the /endgame command.

A score-table will be shown in all cases.  Hint: The server operator
can set the final year while the game is still going by changing the
'end-year' option.  This is nice when the winner is obvious, but you
don't want to play through the boring 'cleanup phase'.


Restoring games:
================

You can restore a saved game by using the '-f' server option, eg:

  |  % civserver -f oursave2001.sav

or, if the save-file was created by a server that compressed it:

  |  % civserver -f oursave2001.sav.gz

Now the players can rejoin the game:

  |  % civclient -n Alexander

Notice how the player-name is specified with the -n option. It's vital
that the player uses the same name as they had when the game was running,
if they're to be allowed in.

The game may then be restarted with the 'start' command as usual.


Native Language Support:
========================

Freeciv supports several languages.

You may choose which local language to use by specifying a "locale".
Each locale has a standard name (e.g., 'de' for German).  If you have
installed Freeciv, you may choose a locale by setting the environment
variable LANG to that locale's standard name before running civserver
and civclient.

For example, assuming you wish to use the German localization, you
would do:

  export LANG; LANG=de   (in the Bourne shell (sh)),
or
  setenv LANG de         (in the C shell (csh)).

(You could do this in your .profile or .login file.)

Sometimes there is a conflict between the local library implementation
and the internal locale determination.  It is often possible to work
around problems with a more detailed descriptor:

  LANG=de_DE.UTF-8

We'd like to know about such problems.  Please report them as bugs
(see BUGS).


Log messages:
=============

Both the client and server print messages known as "log messages".
There are five categories of log messages: "fatal", "error", "normal",
"verbose", and "debug".

By default, fatal, error and normal messages are printed to standard 
output where the client or server was started.  You can direct log 
messages to a file instead of the screen with the "--log filename", 
or "-l filename" command line options.

You can change the level of log messages displayed with "--debug
level" or "-d level" (or instead "-de level" for the Xaw client, since
"-d" is ambiguous between "-debug" and "-display"), where "level" is
0, 1, 2, or 3.  0 means show fatal messages only, 1 means show fatal
and error messages, 2 means fatal, error and normal messages (the
default), and 3 means show all fatal, error, normal, and verbose
messages.

If you compiled with DEBUG defined (an easy way to do this is to
configure with --enable-debug), then you can get debug level messages
by setting the level to 4.  Also, it is possible to control debug
level messages (but not other messages) on a per-file and per-line
basis.  To do this use "--debug 4:str1:str2" (as many strings as you
like, separated by colons) and any filenames which match those strings
as a substring will have debug log messages turned on, and all other
debug messages will be suppressed.  To control lines, use:
"--debug 4:str1,min,max" and for files which match str1 only debug
messages within the specified minimum and maximum lines will be
printed.  Only one set of (min,max) can be applied to each file.

Example:

  |  % civserver -l my.log -d 3

This sends all server log messages to file "my.log", including verbose
level messages.

Example:

  |  % civclient --debug 0

This suppresses all non-fatal client log messages.

Example:

  |  % civserver -d 4:log:civserver,120,500:autoattack

This turns on all fatal, error, normal and verbose messages for the
server, and debug level messages for some specified modules.  Note
that "log" will match "gamelog.c" as well as "log.c".  For
"civserver.c", debug messages between lines 120 and 500 will be
printed.  This example only works if the server was compiled with
DEBUG.
