+# Usage
+#
+
+# Synopsis:
+#
+# make WITH_ZLIB=1 UNIX=1 MANUAL_CONFIG=1
+#
+# (See below for the list of possible options.)
+#
+# Alternately, you can run make without the MANUAL_CONFIG part. It then
+# generates Makefile.config, where you can customize all the options.
+# However beware that for all subsequent calls the option values from
+# Makefile.config take precedence to the commandline options.
+#
+# (That means that you probably want to either specify the options on command
+# line together with MANUAL_CONFIG=1 or you want to specify no commandline
+# options at all.)
+
+# Targets:
+#
+# Defaults to building binary
+# clean: remove intermediate build files
+# mrproper: remove intermediate files and makefile configuration
+# upgradeconf: add new options to old Makefile.config
+# osx: OS X application
+# release: used by OSX to make a dmg file ready to release
+
+# Options:
+#
+# Summary of OS choice defines
+# WIN32: building on Windows
+# UNIX: building on *nix derivate (Linux, FreeBSD)
+# OSX: building on Mac OS X
+# MORPHOS: building on MorphOS
+# BEOS: building on BeOS
+# SUNOS: building on SunOS (Solaris)
+#
+# Summary of library choice defines
+# WITH_ZLIB: savegames using zlib
+# WITH_PNG: screenshots using PNG
+# WITH_SDL: SDL video driver support
+# WITH_COCOA: Cocoa video driver support
+#
+# Summary of other defines:
+# DEBUG: build in debug mode
+# PROFILE: build in profile mode, disables -s and -fomit-frame-pointer
+# TRANSLATOR: build in translator mode (untranslated strings are prepended by
+#             a <TODO> mark)
+# RELEASE: this will be the released version number. It replaces all places
+#          where it normally would print the revision number
+# MIDI: if set, it will use it as custom path to midi player.
+#       If unset, it will use the hardcoded path in the c code
+#       This can still be overriden by the music.extmidi openttd.cfg option.
+# WITH_DIRECTMUSIC: enable DirectMusic MIDI support
+# WITH_NETWORK: enable networking
+# DEDICATED: allows compilation on UNIX without SDL. Useful for dedicated servers
+# MAX_NUM_AUTOSAVES: sets the number of autosaves the games will make before starting
+#		to overwrite the old ones. If not set, the game will use 16.
+#		NOTE: assign a number, not a string of a number
+#
+# Paths:
+# INSTALL: If not set, the game uses the directory of the binary to
+# store everything (lang, data, gm, save and openttd.cfg), this is the `old' behaviour.
+# In this case, none of the following paths are used, you also should _not_
+# use `make install', but copy the required stuff yourself (or just play out
+# of you source directory, which should work fine).
+# If you want to use `make install' to install the game globally, you should
+# define it _before_ you build the game. If you only define INSTALL when you
+# do `make install', the game won't be able to find it's files (so you should
+# also define all the following paths before building).
+#
+# So, the following paths should be defined if INSTALL is defined.
+# None of these paths have to end with /
+# PREFIX:	Normally /usr/local
+# BINARY_DIR:	The location of the binary, normally games. (Will be prefixed
+#		with $PREFIX)
+# DATA_DIR: 	The location of the data (lang, data, gm and scenario), normally
+#		share/games/openttd. (Will be prefixed with $PREFIX) Note that scenarios
+#		are only put here if USE_HOMEDIR is true, otherwise they are placed in
+#		PERSONAL_DIR/scenario
+# ICON_DIR:   The location of the openttd icon. (Will be prefixed with
+# 	$PREFIX).
+# PERSONAL_DIR:	The directory where openttd.cfg and the save folder will be
+#		stored. You cannot use ~ here, define USE_HOMEDIR for that.
+# USE_HOMEDIR:	If this variable is set, PERSONAL_DIR will be prefixed with
+#		~/ at runtime (the user's homedir)
+# SECOND_DATA_PATH  Use this data dir if a file is not found in the data dir in the data path
+# CUSTOM_LANG_PATH  If this is set, it will use the path given to search for lng files
+#		instead of the lang dir in the data path
+#   NOTE: both SECOND_DATA_PATH and CUSTOM_LANG_PATH uses paths relative to where OTTD is opened
+#
+# DEST_DIR:	make install will use this directory instead of the filesystem
+# 		root to install its files. This should normally not be used by
+# 		ordinary users, currently it is only used for the debian
+# 		packaging. This value should only be set when calling `make
+# 		install' and is not saved in Makefile.config
+#               (Note that DESTDIR is checked if DEST_DIR is not set.)
+#
+# STATIC: link statically
+# CYGWIN: build in Cygwin environment
+# MINGW: build with MingW compiler, link with MingW libraries
+#
+# VERBOSE: show full compiler invocations instead of brief progress messages
+#
+# Special for crosscompiling there are some commands available:
+#
+# UNIVERSAL_BINARY: builds a universal binary for OSX. Make sure you got both PPC and x86 libs. Only works with GCC 4 or newer
+# TRIPLE_BINARY: builds a universal binary with the addition of code optimised for G5 (which means a total of 3 binaries in one file)
+# OTTD_PPC, OTTD_PPC970, OTTD_i386: compile for target architecture.
+#    Multiple flags can be used so OTTD_PPC:=1 OTTD_i386:=1 produces the same result as UNIVERSAL_BINARY
+#
+# JAGUAR: Crosscompiling for OSX 1.2.8 (codenamed Jaguar). Only works if OSX is defined too. Only works with GCC 4 or newer
+#	This can be changed to any PPC version of OSX by changing the ppc flags in Makefile.config
+#
+# ENDIAN_FORCE: forces the endian-check to give a certain result. Can be BE, LE or PREPROCESSOR.
+#	PREPROCESSOR is always used on all OSX targets and will make the preprocessor pick the right endian.
+#	this means that you don't have to think about endianess when compiling for OSX.
+#	Very useful for universal binaries and crosscompilers. Not sure if it works on non OSX targets
+# WINDRES: the location of your windres
+# CC_HOST: the gcc of your localhost if you are making a target that produces incompatible executables
+# CFLAGS_HOST: cflags used for CC_HOST. Make it something if you are getting errors when you try to compi
+#		windows executables on linux. (just: CFLAGS_HOST:='-I' or something)

-1.0) About
----- -----
-OpenTTD has 32bpp support. This means: OpenTTD still is 8bpp, but it has the
-posibility to override the graphics with 32bpp. This means that it isn't a
-replacement of grf or newgrf, but simply an addition. If you want to use 32bpp
-graphics of a newgrf, you do need the newgrf itself too (with 8bpp graphics).
-
-
-2.0) The format
----- ----------
-32bpp images are stored in PNG. They should go in:
-  data/sprites/<grfname>/<SpriteID>.png
-
-For example, a grfname would be 'openttd' (without .grf, lowercase), and the
-SpriteID 3, to override the 3rd sprite in openttd.grf with a 32bpp version.
-
-The format of this PNG can be almost anything, but we advise to use RGBA
-format. Alpha-channel is fully supported.
-
-As the core of OpenTTD is 8bpp, and because you of course want company colours
-in your images, you will need to add a mask for every sprite that needs colour
-remapping. The name is simular as above, only you have to put a 'm' behind the
-SpriteID. This image should be a 8bpp palette image, where the palette is the
-OpenTTD palette. Upon load of the PNG, the mask is loaded too, and overrides
-the RGB (not the Alpha) of the original PNG image, and replacing it with a
-8bpp color remapped and converted to 32bpp.
-
-Another thing that OpenTTD needs in your png, is 2 tEXt chunks: x_offs and
-y_offs. This to define the x- and y-offset, of course. Use the tool we supply
-to add this information. Sadly enough most graphical editors trashes those
-chunks upon save, so you have to readd it every time you save your image.
-
-Your images should be the same as the grf, in size.

-1.0) strgen usage
----- ------------
-This guide is only interesting for people who want to alter something
-themselves without access to translator.openttd.org. Please note that
-your compiled language file will only be compatible with the OpenTTD version
-you have downloaded english.txt, the master language file, for. While this is
-not always true, namely when changes in the code have not touched language
-files, your safest bet is to assume this 'limitation'.
-As a first step you need to compile strgen. This is as easy as typing
-'make strgen'. You can download the precompile strgen from:
-http://www.openttd.org/download-strgen
-
-strgen takes as argument a txt file and translates it to a lng file, allowing
-it to be used inside OpenTTD. strgen needs the master language file
-english.txt to work. Below are some examples of strgen usage.
-
-1.1) Examples
----- --------
-Example 1:
-if you are in the root of your working copy (svn code), you should type
-strgen/strgen -s lang lang/english.txt
-to compile englist.txt into english.lng. It will be placed in the lang dir
-
-Example 2:
-you only have the strgen executable (no working copy) and you want to compile
-a txt file in the same directory. You should type
-./strgen english.txt
-and you will get and english.lng in the same dir
-
-Example 3:
-you have strgen somewhere, english.txt in /usr/openttd/lang and you want the
-resulting language file to go to /tmp. Use
-./strgen -s /usr/openttd/lang -d /tmp english.txt
-
-You can interchange english.txt to whichever language you want to generate a
-.lng file for.
-
-1.2) strgen command switches
----- -----------------------
--v | --version
-strgen will tell what svn revision it was last modified
-
--t | --todo
-strgen will add <TODO> to any untranslated/missing strings and use the english
-strings while compiling the language file
-
--w | --warning
-strgen will print any missing strings or wrongly translated (bad format)
-to standard error output(stderr)
-
--h | --help | -?
-Print out a summarized help message explaining these switches
-
--s | --source_dir
-strgen will search for the master file english.txt in the directory specified
-by this switch instead of the current directory
-
--d | --dest_dir
-strgen will put <language>.lng in the directory specified by this switch; if
-no dest_dir is given, output is the same as source_dir

+This is a guide to compile strgen on gcc
+
+All this is done in the makefile, so it's only interesting for people, who wants to alter something themselves (translators)
+
+HOWTO compile lng files:
+
+First you get strgen compiled (look below/download nightly build/run makefile)
+
+strgen takes the argument of a txt file and translates it to a lng file and places that lng file in the same dir as the txt file.
+
+Example 1:
+if you are in the root of your working copy (svn code), you should type

+to compile englist.lng. It will be placed in the lang dir
+
+Example 2:
+you have strgen but not the source and you want to compile a txt file in the same dir. YOu should type
+./strgen english.txt
+and you will get english.lng in the same dir
+
+You can change english to whatever language you want
+
+Commands used by strgen
+
+-v --version
+strgen will tell what svn revision it is based on
+
+-t
+strgen will add <TODO> to the missing strings and use the english strings while compiling
+this will need english.txt to be present
+
+-w
+strgen will print any missing strings to standard error output(stderr)
+this will need english.txt to be present
+
+here are a very useful tool for translators:
+http://openttd.rulez.org/
+
+
+HOWTO compile strgen:
+(this should be useless as you can just type make)
+Goto the main dir
+Compile by typing
+gcc strgen/strgen.c -o strgen/strgen -DUNIX
+or if you want it to tell the revision too
+gcc strgen/strgen.c rev.o -o strgen/strgen -DUNIX -DWITH_REV (this is the one the makefile uses)
+
+you now have a program called strgen in the strgen directory

docs/Manual.txt

@@ -0,0 +1,102 @@
+Welcome to the manual for OpenTTD. The latest release version at the time of  writing is 0.3.2.
+
+1 Obtaining OpenTTD.
+
+You can obtain built binaries of OpenTTD for the 4 supported platforms - Win32, Linux,-x86, BeOS 5 and MacOS-X from the projects Sourceforge page, at http://sourceforge.net/projects/openttd . For the non-Win32 builds you will need libSDL.so, libpng.so and zlib.so compiled for your platform. Some builds will include these. 
+
+If you use another platform, such as FreeBSD, which has POSIX file i/o and an SDL port, you should be able to build OpenTTD from its source. This is available in the proejcts Subversion repository at svn://svn.openttd.com . The module name is "trunk". 
+
+1.1 Building OpenTTD.
+
+Once you have obtained a recent copy of the source, you must build it. Windows build instructions will be provided later.
+
+On UNIX platforms (including OS-X and BeOS), ensure you have a recent GCC (2.9  or above, or 3 and above).You will also need SDL development headers and libraries (libSDL 1.2 or higher). For PNG screenshot support and zlib compressed games, you will need libpng 1.0.12 or higher and zlib 1.2 or higher.
+
+Most UNIX platforms:
+Use make or gmake to compile OpenTTD. You can adjust Makefile.config to compile with other options.
+
+BeOS:
+On BeOS, run ./configure and then use jam. There are a variaty of options you can pass to your build tool, these are reported by ./configure.
+
+
+1.2 Installing OpenTTD.
+
+On Windows, insert your "Transport Tycoon Deluxe for Windows 95" disk. You can use a DOS version, but your graphics will be purple. NB: Even if your version of Transport Tycoon Deluxe ran on Windows 95, it may still be the DOS version. Then run the OpenTTD installer. 
+
+On UNIX platforms; decompress your OpenTTD archive, or otherwise run the installer. You should be left with an OpenTTD directory on your system. In this directory, make a subdirectory called 'data', and into this place the sample.cat file and all the .grf files from the install CD of 'Transport Tycoon Deluxe for Windows 95". 
+(Alternatively you can use the TTD GRF files from the DOS version: TRG1.GRF, TRGC.GRF, TRGH.GRF, TRGI.GRF, TRGT.GRF. A few minor graphical glitches with the DOS graphics remain. E.g. the autorail button in the rail toolbar doesn't look as nice as with the Windows graphics.)
+
+If you want MIDI music, copy the 'gm' folder from the original game directory/CD to the OpenTTD folder.
+
+1.3 Running OpenTTD.
+
+On Windows, you can use a third-party launcher such as OTTD-Launcher to run OpenTTD directly from Explorer. Otherwise, navigate via the command prompt to the correct location and launch ttd.exe.
+
+On Linux, navigate at the shell to the correct location and run ttd.
+
+On BeOS and Mac OS-X, just double click the ttd binary in the Tracker/Finder. You can also start from the shell.
+
+1.4 Configuring OpenTTD
+
+OpenTTD's launch menu contains three configuration menus - Difficulty Settings, Configure Patches and Game Settings. Most of these menus can be configured from within a running game as well. 
+
+Difficulty Settings lets you configure settings that affect the difficulty of playing the game. These include when your (computer-controlled) competitors can start building, how many of them there are, and how intelligent they are. You can also control how much the subsidy mutliplier is for subsidised routes, and how stable/volitile the in-game economy is. You can also set how you want the terrain to be configured in a random game.
+
+Game Settings lets you set regional settings - currency, language, town names, etc. It also lets you select the resolution to run the game at, as well as the screenshot format to use.
+
+Configure Patches lets you select which patches to use in the game. This allows you to set the game play to either original Transport Tycoon Deluxe compatible mode or a mode more like playing under TTD-Patch. Patches include building on slopes, longer bridges, longer trains, pre-signals, and TTD-Patch compatible handling of non-stop orders.
+
+2.1 Gameplay
+
+This section of the manual is written with the assumption that you already know the gameplay basics of Transport Tycoon Deluxe, on either DOS or Windows. As you must have the Windows Transport Tycoon Deluxe CD to play OpenTTD, you should either have a paper manual or the complete manual in PDF format on the disk. This section will only cover the gameplay differences from Transport Tycoon Deluxe.
+
+2.2 Station Construction
+
+In OpenTTD, you can build rail stations up to seven squares long and with up to seven platforms. You can also have stations spreading across far larger distances, allowing a large rail station to be connected to a large airport, for instance. 
+
+However, there is an even more noticable difference in rail station construction. You may now add platforms and lenght to a station after it has been built, and you may also add platforms of a different type. Users of TTDPatch will be used to this behaviour. But beyond what TTDPatch has, you can make stations of uneven lenght/width, and even ones with perpendicular tracks. You can also delete single tiles or tracks from a station, by holding down Shift before pressing the station construction button.
+
+2.3 Checkpoint Stations
+
+
+Checkpoint stations (the small blue item in the rail construction window) are small 1x1 stations. They must be built on top of pre-existing track. They do not accept or produce carge of any kind. They exist solely for use as route points. They become useful when dealing with large networks  where trains may attempt to route themselves along undesirable or impossible routes. As an alternative to checkpoint stations, you can also direct trains to visit depots along the way. This has the advantage of also servicing the train and hence the train will rarely to never need to depart from its route to be serviced. 
+
+2.4 Freeform Rail Laying.
+
+Along side the other rail laying buttons, you will see a button that looks somewhat like a crossing. This is the freeform rail laying tool., and it allows you to drag rail in any direction to lay it. This has a number of advantages, one of the main ones being that it can seriously speed up the laying of diagonal tracks.
+
+2.5 Vehicle Queuing (with Quantum Effects)
+
+This useful addition to OpenTTD means that road vehicles will queue outside a road station to  wait for a space rather than attempt to enter it immediately. As anyone who has operated a large road network with busy stations will know, road vehicles quickly pile up inside stations. This will prevent that. The Quantum Effects are down to a bug in the game that means that mutliple vehicles will often only take up one space in the queue. However, this is almost too useful to fix, and should still be there in later versions. This can be enabled/disabled.
+
+2.6 Building On Slopes
+
+This allows you to build roads, rails, stations and depots on slopes. It also allows the construction of trasmitters and lighthouses on slopes in the scenario editor. There are some minor differences between OpenTTD's and TTD-Patch's handling of building on slopes, the main one being that  bridges must still have solid land at their endings.
+
+2.7 Long Bridges
+
+OpenTTD allows you to constuct bridges up to 127 squares - half the size of the current map. This means that the crossing of large estuaries, such at the Bristol Channel in the original "West Country 90210" scenario can be acheived with one bridge instead of many bridges with staging points. 
+
+2.8 Long trains
+
+OpenTTD allows trains of around 60 cars length, hence allowing you to use 7 square stations to their capacity and beyond.
+
+2.9 Speed Display
+
+This addition to OpenTTD allows you to see the current speed of any vehicle in their status window. Just open the status window of a vehicle and you can see the speed at that given moment. This allows you to see wheter better bridges, flatter/straighter track or more powerful engines could be used to increase the speed of a vehicle
+
+2.10 More Trains, More Ships, More Everything!
+
+Virtually any settings - train numbers, start date, what vehicles your competitors can use, etc - can be set in OpenTTD. Just use the Configure Patches menu on the main screen.
+
+2.11 Network Play 
+
+See multiplayer.txt for more info.
+
+2.12 Rail Recycling.
+
+This button, at the end of the train construction window, lets you 'recycle' track to a new type. It also works on bridges, tunnels, stations and depots.
+
+2.13 Canal Building
+
+This button, at the end of the water construction window, lets you build canals and shiplifts across the landscape. These act just like normal water.

+There are currently two different downloads for OSX, one is named osx, while the other one is named osx-jaguar
+
+The reason for this is that Apple added more functionality to 10.3 and to make use of that, it will no longer run on OSX 10.2 (codenamed Jaguar). To make the game useable on Jaguar, then a special download is available, but it will miss the bugfixes/features, that relies on newer functionality.
+
+The general download is a universal binary and should work great on all macs using 10.3.9 or newer, no matter what processor it got. You should at all time avoid the Jaguar Build if possible.
+
+Technically the universal binary is a triple binary because it contains code for 3 CPUs and the CPUs in question are PPC (G3+G4), G5 and Intel. The Jaguar build is only optimised for PPC and other (newer) CPUs will not benefit so much from their advanced features. This is another reason to avoid the Jaguar build. It's generally slower on modern CPUs.

-in my opinion!), but until then, OpenTTD 0.5 and later can only be built with GCC.

+A Note About Subversion Revision Numbers
+----------------------------------------
+
+The project file uses a bit of a hack to find out the SVN revision number and
+create an appropriate rev.c file. You'll need the SVN tools in your path
+(specifically, "svnversion"). If "svnversion" can't be found, a generic rev.c
+with the revision set to "norev000" will be created. To specifically force a
+version number, set the environment variable "RELEASE" to the number (eg, "0.3.6")
+-before- starting the Open Watcom IDE (which must be launched from the same shell
+session). Also, beware, as you WILL cause incompatibilities if you try to
+play a multiplayer game with a different version.
+
+Compiling
+---------
+
+To compile, open the os/os2/openttd.wpj file in the IDE and first build
+the strgen.exe target. This will build the .lng file generator, and will
+also attempt to build all the language files (plus the table\strings.h
+file which is required for openttd.exe to be built). Once strgen.exe and
+the language files are built successfully, you can build the openttd.exe
+target.

-Compiling OpenTTD using Microsoft Visual C++
-Last updated: 2010-01-03
---------------------------------------------
-PLEASE READ THE ENTIRE DOCUMENT BEFORE DOING ANY ACTUAL CHANGES!!
-
-
-SUPPORTED MSVC COMPILERS
-------------------------
-OpenTTD includes projects for MSVC 2005.NET and MSVC 2008.NET. Both will
-compile out of the box, providing you have the required libraries/headers;
-which ones, see below. There is no support for VS6 or MSVC 2002, or
-MSVC 2003.NET. You are therefore strongly encouraged to either upgrade to
-MSVC 2008 Express (free) or use GCC.
-
-
-1) REQUIRED FILES
------------------
-You might already have some of the files already installed, so check before
-downloading; mostly because the DirectX SDK and Platform SDK are about
-500MB each.
-Download the following files:
-
-	* openttd-useful.zip (http://binaries.openttd.org/extra/openttd-useful/)
-	* DirectX 8.1 SDK (http://neuron.tuke.sk/~mizanin/eng/Dx81sdk-include-lib.rar) (or alternatively the latest DirectX SDK from Microsoft)
-	* MS Windows Platform SDK (http://www.microsoft.com/downloads/details.aspx?FamilyId=A55B6B43-E24F-4EA3-A93E-40C0EC4F68E5&displaylang=en)
-	* afxres.h (http://www-d0.fnal.gov/d0dist/dist/packages/d0ve/devel/windows/AFXRES.H)
-
-...and of course the newest source from svn://svn.openttd.org/trunk
-
-You need an SVN-client to download the source from subversion:
-
-	* CLI Subversion (http://subversion.tigris.org/)
-	* GUI TortoiseSVN (http://tortoisesvn.tigris.org/)
-
-
-2) INCLUDES AND LIBRARIES
--------------------------
-Put the newly downloaded files in the VC lib\ and include\ directories; where
-"C:\Program Files\Microsoft Visual Studio 9.0\VC" is your location of Visual C.
-If you are compiling for an x64 system, use the include\ and lib\ directories
-from the win64/ folder.
-
-	* openttd-useful.zip\include\*
-	* afxresh.h
-	to >	C:\Program Files\Microsoft Visual Studio 9.0\VC\Include
-
-	* openttd-useful.zip\lib\*
-	to >	C:\Program Files\Microsoft Visual Studio 9.0\VC\Lib
-
-Custom directories might be recommended, check 2.2)
-
-
-2.1) INCLUDES AND LIBRARIES - DIRECTX/PLATFORM SDK
---------------------------------------------------
-Basically the same procedure as with the useful zip file, providing
-you are not using the Microsoft installer. Put the include files in the
-include\ directory and the library files to the Lib\ directory.
-
-It is recommended to use custom directories so you don't overwrite any
-default header or library files.
-
-
-2.2) CUSTOM DIRECTORIES
------------------------
-If you have put the above include and/or library files into custom folders,
-MSVC will not find them by default. You need to add these paths to VC through:
-
-Tools > Options > Projects and Solutions > VC++ Directories > show directories for
-
-	* Include files: Add the DirectX/Platform SDK include dir you've created
-	* Library files: Add the path to the SDK custom lib dir
-
-NOTE: make sure that the directory for the DirectX SDK is the first one in the
-list, above all others, otherwise compilation will most likely fail!!
-
-
-3) TTD GRAPHICS FILES
----------------------
-See section 4.1 of readme.txt for the required 3rdparty files and how to install them.
-
-
-4) COMPILING
-------------
-Open trunk/openttd_vs[89]0.sln
-Set the build mode to 'Release' in
-Build > Configuration manager > Active solution configuration > select "Release"
-Compile...
-
-If everything works well the binary should be in trunk/objs/Win[32|64]/Release/openttd.exe
-
-
-5) EDITING, CHANGING SOURCE CODE
---------------------------------
-Set the build mode (back to) 'Debug'
-Change the startup project to openttd by right-clicking the 'openttd' project
-in the Solution Explorer and selecting 'Set as Startup Project'. The 'openttd'
-project should now show up bold instead of 'strgen'.
-
-
-6) PROBLEMS?
-------------
-If compilation fails, double-check that you are using the latest SVN (!)
-source. If it still doesn't work, check in on IRC (irc://irc.oftc.net/openttd),
-to ask about reasons; or just wait. The problem will most likely solve itself
-within a few days as the problem is noticed and fixed.

-OpenTTD's admin network
-Last updated:    2011-01-20

-
-
-1.0) Preface
----- -------
-  The admin network provides a dedicated network protocol designed for other
-  applications to communicate with OpenTTD. Connected applications can execute
-  console commands remotely (rcon commands) with no further authentication.
-  Furthermore information about clients and companies can be provided.
-
-  Admin applications remain connected when starting a new game or loading a saved
-  game in contrast to normal OpenTTD clients that get disconnected.
-
-  This document describes the admin network and its protocol.
-
-  Please refer to the mentioned enums in src/network/core/tcp_admin.h
-
-  Please also note that further improvements to the admin protocol can mean that
-  more packet types will be sent by the server. For forward compatibility it is
-  therefore wise to ignore unknown packets. Future improvements might also add
-  additional data to packets. This data should be ignored. Data will never be
-  removed from packets in later versions, except the possibility that complete
-  packets are dropped in favour of a new packet.
-  This though will be reflected in the protocol version as announced in the
-  ADMIN_PACKET_SERVER_PROTOCOL in section 2.0).
-
-  A reference implementation in Java for a client connecting to the admin interface
-  can be found at: http://dev.openttdcoop.org/projects/joan
-
-
-2.0) Joining the network
----- -------------------
-  Create a TCP connection to the server on port 3977. The application is
-  expected to authenticate within 10 seconds.
-
-  To authenticate send a ADMIN_PACKET_ADMIN_JOIN packet.
-
-  The server will reply with ADMIN_PACKET_SERVER_PROTOCOL followed directly by
-  ADMIN_PACKET_SERVER_WELCOME.
-
-  ADMIN_PACKET_SERVER_PROTOCOL contains details about the protocol version.
-  It is the job of your application to check this number and decide whether
-  it will remain connected or not.
-  Furthermore, this packet holds details on every AdminUpdateType and the
-  supported AdminFrequencyTypes (bitwise representation).
-
-  ADMIN_PACKET_SERVER_WELCOME contains details on the server and the map,
-  e.g. if the server is dedicated, its NetworkLanguage, size of the Map, etc.
-
-  Once you have received ADMIN_PACKET_SERVER_WELCOME you are connected and
-  authorized to do your thing.
-  The server will not provide any game related updates unless you ask for them.
-  There are four packets the server will none the less send, if applicable:
-    - ADMIN_PACKET_SERVER_ERROR
-    - ADMIN_PACKET_SERVER_WELCOME
-    - ADMIN_PACKET_SERVER_NEWGAME
-    - ADMIN_PACKET_SERVER_SHUTDOWN
-
-  However, ADMIN_PACKET_SERVER_WELCOME only after a ADMIN_PACKET_SERVER_NEWGAME
-
-
-3.0) Asking for updates
----- ------------------
-  Asking for updates is done with ADMIN_PACKET_ADMIN_UPDATE_FREQUENCY.
-  With this packet you define which update you wish to receive at which
-  frequency.
-
-  Note: not every update type supports every frequency. If in doubt, you can
-  verify against the data received in ADMIN_PACKET_SERVER_PROTOCOL.
-
-  The server will not confirm your registered update. However, asking for an
-  invalid AdminUpdateType or a not supported AdminUpdateFrequency you will be
-  disconnected from the server with NETWORK_ERROR_ILLEGAL_PACKET.
-
-  Additional debug information can be found with a debug level of net=3.
-
-  ADMIN_UPDATE_DATE results in the server sending:
-    - ADMIN_PACKET_SERVER_DATE
-
-  ADMIN_UPDATE_CLIENT_INFO results in the server sending:
-    - ADMIN_PACKET_SERVER_CLIENT_JOIN
-    - ADMIN_PACKET_SERVER_CLIENT_INFO
-    - ADMIN_PACKET_SERVER_CLIENT_UPDATE
-    - ADMIN_PACKET_SERVER_CLIENT_QUIT
-    - ADMIN_PACKET_SERVER_CLIENT_ERROR
-
-  ADMIN_UPDATE_COMPANY_INFO results in the server sending:
-    - ADMIN_PACKET_SERVER_COMPANY_NEW
-    - ADMIN_PACKET_SERVER_COMPANY_INFO
-    - ADMIN_PACKET_SERVER_COMPANY_UPDATE
-    - ADMIN_PACKET_SERVER_COMPANY_REMOVE
-
-  ADMIN_UPDATE_COMPANY_ECONOMY results in the server sending:
-    - ADMIN_PACKET_SERVER_COMPANY_ECONOMY
-
-  ADMIN_UPDATE_COMPANY_STATS results in the server sending:
-    - ADMIN_PACKET_SERVER_COMPANY_STATS
-
-  ADMIN_UPDATE_CHAT results in the server sending:
-    - ADMIN_PACKET_SERVER_CHAT
-
-  ADMIN_UPDATE_CONSOLE results in the server sending:
-    - ADMIN_PACKET_SERVER_CONSOLE
-
-
-  ADMIN_UPDATE_CMD_LOGGING results in the server sending:
-    - ADMIN_PACKET_SERVER_CMD_LOGGING
-
-3.1) Polling manually
----- ----------------
-  Certain AdminUpdateTypes can also be polled:
-    - ADMIN_UPDATE_DATE
-    - ADMIN_UPDATE_CLIENT_INFO
-    - ADMIN_UPDATE_COMPANY_INFO
-    - ADMIN_UPDATE_COMPANY_ECONOMY
-    - ADMIN_UPDATE_COMPANY_STATS
-    - ADMIN_UPDATE_CMD_NAMES
-
-  ADMIN_UPDATE_CLIENT_INFO and ADMIN_UPDATE_COMPANY_INFO accept an additional
-  parameter. This parameter is used to specify a certain client or company.
-  Setting this parameter to UINT32_MAX (0xFFFFFFFF) will tell the server you
-  want to receive updates for all clients or companies.
-
-  Not supported AdminUpdateType in the poll will result in the server
-  disconnecting the application with NETWORK_ERROR_ILLEGAL_PACKET.
-
-  Additional debug information can be found with a debug level of net=3.
-
-
-4.0) Sending rcon commands
----- ---------------------
-  Rcon runs separate from the ADMIN_UPDATE_CONSOLE AdminUpdateType. Requesting
-  the execution of a remote console command is done with the packet
-  ADMIN_PACKET_ADMIN_RCON.
-
-  Note: No additional authentication is required for rcon commands.
-
-  The server will reply with a ADMIN_PACKET_SERVER_RCON packet. Applications
-  will not receive the answer twice if they have asked for the AdminUpdateType
-  ADMIN_UPDATE_CONSOLE, as the result is not printed on the servers console
-  (just like clients rcon commands).
-
-  Furthermore, sending a 'say' command (or any similar command) will not
-  be sent back into the admin network.
-  Chat from the server itself will only be sent to the admin network when it
-  was not sent from the admin network.
-
-
-5.0) Sending chat
----- ------------
-  Sending a ADMIN_PACKET_ADMIN_CHAT results in chat originating from the server.
-
-  Currently four types of chat are supported:
-    - NETWORK_ACTION_CHAT
-    - NETWORK_ACTION_CHAT_CLIENT
-    - NETWORK_ACTION_CHAT_COMPANY
-    - NETWORK_ACTION_SERVER_MESSAGE
-
-  NETWORK_ACTION_SERVER_MESSAGE can be sent to a single client or company
-  using the respective DestType and ID.
-  This is a message prefixed with the 3 stars, e.g. *** foo has joined the game
-
-5.1) Receiving chat
----- -------------
-  Register ADMIN_UPDATE_CHAT at ADMIN_FREQUENCY_AUTOMATIC to receive chat.
-  The application will be able to receive all chat the server can see.
-
-  The configuration option network.server_admin_chat specifies whether
-  private chat for to the server is distributed into the admin network.
-
-
-6.0) Disconnecting
----- -------------
-  It is a kind thing to say good bye before leaving. Do this by sending the
-  ADMIN_PACKET_ADMIN_QUIT packet.
-
-
-7.0) Certain packet information
----- --------------------------
-  All ADMIN_PACKET_SERVER_* packets have an enum value greater 100.
-
-  ADMIN_PACKET_SERVER_WELCOME
-    Either directly follows ADMIN_PACKET_SERVER_PROTOCOL or is sent
-    after a new game has been started or a map loaded, i.e. also
-    after ADMIN_PACKET_SERVER_NEWGAME.
-
-  ADMIN_PACKET_SERVER_CLIENT_JOIN and ADMIN_PACKET_SERVER_COMPANY_NEW
-    These packets directly follow their respective INFO packets. If you receive
-    a CLIENT_JOIN / COMPANY_NEW packet without having received the INFO packet
-    it may be a good idea to POLL for the specific ID.
-
-  ADMIN_PACKET_SERVER_CMD_NAMES and ADMIN_PACKET_SERVER_CMD_LOGGING
-    Data provided with these packets is not stable and will not be
-    treated as such. Do not rely on IDs or names to be constant
-    across different versions / revisions of OpenTTD.
-    Data provided in this packet is for logging purposes only.
