+# 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
+
+# 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
+#
+# Summary of library choice defines
+# WITH_ZLIB: savegames using zlib
+# WITH_PNG: screenshots using PNG
+# WITH_SDL: SDL video driver support
+#
+# Summary of other defines:

- - 'pre_server.scr' is executed before the servers tcp stack is started [in-game only]
- - 'pre_dedicated.scr' is executed before the servers tcp stack is started [dedicated only]
-

-32bpp and OpenTTD
-=================
-
-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).
-
-
-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.
-
-An other 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.

-STRGEN USAGE
-------------
-This guide is only interesting for people who want to alter something
-themselves without access to WT2 (translator2.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 also download a precompiled binary from a release,
-nightly, etc.
-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.
-
-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.
-
-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

+
+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

+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.

As an alternative to checkpoint stations, you can also direct trains to visit depots along the way.

+Compiling and developing OpenTTD on MandrakeLinux 10.0 Official
+
+A quick guide to get started with OpenTTD development on Linux.
+---------------------------------------------------------------
+
+1.) RPMs:
+
+Most packages that are required for development (like gcc) should already be installed on your box. You will require those RPMs additionally:
+- libsdl1.2-devel-1.2.7-2mdk
+- subversion-1.0.1-1mdk (+ dependencies)
+- libsvn_ra_svn1_0-1.0.1-1mdk
+
+
+2.) Subversion:
+
+To obtain the source code from the subversion server type
+  $ svn co svn://svn.openttd.com/openttd/trunk openttd
+from command line to dump the code into the directory 'openttd'.
+
+To update your working copy to the latest revision use
+  $ svn update
+Don't worry, your version will be merged with the latest version.
+
+The command
+  $ svn diff > mypatch.diff
+creates a patch file (aka diff file) which you can submit to the developers to share your improvements.
+
+You can undo changes to a file with
+  $svn revert filename
+
+
+3.) Required data files:
+
+Copy the following files from the WINDOWS version of Transport Tycoon Deluxe to openttd/data/
+  sample.cat
+  trg1r.grf
+  trgcr.grf
+  trghr.grf
+  trgir.grf
+  trgtr.grf
+  
+  
+4.) Compiling and running:
+
+Compile OpenTTD with
+  $ make
+and run it with
+  $ ./ttd
+
+     
+5.) Playing the soundtrack:
+
+If you want the original TTD music you need to copy the whole /gm/ directory from Windows. Additionally the TiMidity driver is required:
+  TiMidity++-2.12.0-0.pre1.4mdk (+ dependencies)
+To run OpenTTD with music support type
+  $ ./ttd -m extmidi

-OpenTTD: OS/2 version
-=====================
-
-OpenTTD has been ported to work on OS/2 4.x or later (including
-eComStation). The game should work as well as it does on Windows
-or other platforms: the main issues you may encounter are graphics
-card problems, but that is really the fault of SDL.
-
-=========================
-USING OPENTTD FOR OS/2
-=========================
-
-LIBRARIES REQUIRED FOR END USERS
---------------------------------
-
-SDL.DLL (SDL 1.2.7) and FSLib.dll are required to use this program:
-these can be downloaded from the Files section at
-http://sourceforge.net/projects/openttd/ - see "os2-useful-v1.1.zip".
-Version 20051222 of SDL or later is required. This can be found at
-http://sdl.netlabs.org/.
-
-Please note that earlier SDL releases will probably NOT work with
-OpenTTD. If you experience problems with OpenTTD, please check
-your SDL and FSLib.dll versions (both must match).
-
-Note that to actually play the game, I have found in my own
-experience that a version of the Scitech Display Drivers or its later
-incarnation (see www.scitech.com) are necessary for it to work. If
-you have trouble with your native drivers, try the Scitech drivers
-and see if they help the problem.
-
-KNOWN ISSUES
-------------
-
-- If an error occurs during loading, the OS/2 error message window
-  is not always displayed.
-
-A NOTE ABOUT MUSIC
-------------------
-
-OpenTTD includes a music driver which uses the MCI MIDI system. Unfortunately,
-due to the lack of proper MIDI hardware myself, I have been unable to test it,
-but during testing, I found that when MIDI was enabled, I got no sound
-effects. I therefore decided to DISABLE music by default.
-
-To enable music, start OpenTTD with the command line:
-
-   openttd -m os2
-
-If I hear enough responses that both music and sound work together (it might
-just be my system), I'll have the defaults changed.
-
-Please note also that the GCC version does not currently support the MCI MIDI
-system.
-
-
-A NOTE ABOUT DEDICATED MULTIPLAYER SERVERS
-------------------------------------------
-
-To start a dedicated multiplayer server, you should run the dedicated.cmd
-file. This enables OpenTTD to open up a VIO console window to display
-its output and gather any necessary input. Running "openttd -D"
-directly will result in the console not being displayed. You may
-still pass any other parameters ('-D' is already passed) to
-dedicated.cmd.
-
-You can find the dedicated.cmd file in the os/os2 directory.
-
-=========================
-BUILDING THE OS/2 VERSION
-=========================
-
-Compiler
---------
-
-Innotek GCC, an OS/2 port of the popular GCC compiler, was used to build OpenTTD.
-See www.innotek.de for more information. You WILL need a reasonably UNIX-like
-build environment in order to build OpenTTD successfully - the following link
-may help to set one up (although some of the links from that page are broken):
-
-   http://www.mozilla.org/ports/os2/gccsetup.html
-
-Alternatively, Paul Smedley's ready-to-go GCC build environment has been known to
-successfully build the game:
-
-   http://www.smedley.info/os2ports/index.php?page=build-environment
-
-To build, you should, if your environment is set up well enough, be able to just
-type `./configure' (or `sh configure' if you're using the OS/2 shell) and `make'.
-
-You may have to manually specify `--os OS2' on the configure command line, as
-configure cannot always detect OS/2 correctly.
-
-A note on Open Watcom
----------------------
-
-Open Watcom C/C++ was previously used to build OpenTTD (version 0.4.x and earlier).
-However, due to advanced C++ features used in the YAPF portion of OpenTTD 0.5
-in particular, the compiler is no longer able to build the game at the moment.
-Hopefully one day Open Watcom will be able to catch up and we will be able to build
-the game once again (it's easier than getting an OS/2 UNIX-like environment set up
-in my opinion!), but until then, OpenTTD 0.5 and later can only be built with GCC.
-
-Libraries Required
-------------------
-
-The following libraries are required. To build zlib and libpng, I
-simply added the required files (watch out for sample programs, etc)
-to an IDE project file and built a library. Do not use the makefiles
-provided, they are not designed for Watcom (apart from SDL):
-
-- zlib
-  http://www.zlib.org/
-
-- libpng
-  http://www.libpng.org/
-
-- SDL for OS/2
-  ftp://ftp.netlabs.org/pub/sdl/sdl-1.2.7-src-20051222.zip used for
-  0.4.7
-
-- Freetype
-  http://freetype.sourceforge.net/
-
-Currently, there are no pre-built libraries available for GCC. If you manage to get
-OpenTTD working on Watcom though (do let us know if this is the case!), pre-built
-versions can be downloaded from the Files section at
-http://sourceforge.net/projects/openttd/ - see "os2-useful-v1.1.zip".
-
-Contact Information
--------------------
-
-If you have any questions regarding OS/2 issues, please contact me
-(owen@owenrudge.net) and I'll try to help you out. For general OpenTTD
-issues, see the Contacting section of readme.txt.
-
-Thanks to Paul Smedley for his help with getting OpenTTD to compile under GCC on OS/2.

-Compiling OpenTTD using Microsoft Visual C++
-January 2, 2007
---------------------------------------------
-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 2005 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://sf.net/project/showfiles.php?group_id=103924&package_id=114307)
-	* 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/servlets/ProjectDocumentList?folderID=91)
-	* GUI TortoiseSVN (http://tortoisesvn.tigris.org/download.html)
-
-
-2) INCLUDES AND LIBRARIES
--------------------------
-Put the newly downloaded files in the VC lib\ and include\ directories; where
-"C:\Program Files\Microsoft Visual Studio 8\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 8\VC\Include
-
-	* openttd-useful.zip\lib\*
-	to >	C:\Program Files\Microsoft Visual Studio 8\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
----------------------
-Copy the following files from Transport Tycoon Deluxe to the bin/data folder
-
-	* sample.cat
-	* trg1r.grf
-	* trgcr.grf
-	* trghr.grf
-	* trgir.grf
-	* trgtr.grf
-
-
-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.

+In VC6.0: Tools -> Options -> Directories -> show directories for:
+a) include files (the include dir: D:\Program Files\Microsoft Visual Studio\VC98\DirectX 7 SDK\include )
+b) libraru files (the lib dir, D:\Program Files\Microsoft Visual Studio\VC98\DirectX 7 SDK\lib )

-Multiplayer Manual for OpenTTD (0.3.5)
-=======================================
+Multiplayer Manual for OpenTTD
+----------------------------------------
 
 1. Starting a Server
----------------------
-
- - Click "multiplayer" on the startup screen
- - Click "start server"
- - Type in a game name
- - Select the type of game ('LAN/Internet' or 'Internet (advertise)'. With the last one
-    other people are able to see you online. Else they need your IP and port to join)
- - Click "start game", "load game" or "load scenario"
- - Start playing
-
 
+ - click "multiplayer" on the startup screen
+ - click "start server"
+ - type in a game name
+ - click "start game" ,"load game" or "load scenario"
+ 
 2. Connecting to a Server
---------------------------
-
- - Click "multiplayer" on the startup screen
-
- - If you want to connect to any network game in your LAN click on 'LAN', then on
-    'Find Server'
- - If you want to see which servers all online on the Internet, click on 'Internet'
-    and 'Find Server'
-
- - If there were more then one server
+ 
+ - click "multiplayer" on the startup screen
+ 
+ - if you want to connect to any network game in your LAN click "find server"
+ 
+ - if there were more then one server 
    - select one in the list below the buttons
-   - click on 'join game'
+   - click on "join game".
 
- - If you want to play and you have the ip or hostname of the game server you want connect to.
-   - click add server
+ - if you want to play over the internet you should have the ip of the game server you want connect to.
+   - click direct connect
    - type in the ip address or hostname
    - if you want to add a port use :<port>
-
- - Now you can select a company and press: "Join company", to help that company
- - Or you can press "Spectate game", to spectate the game
- - Or you can press "New company", and start your own company (if there are slots free)
-
- - You see a progressbar how far you are with joining the server.
-
- - Happy playing
-
-
+   - if you want to connect as an special player use #<player-no>
+   
 3. Connecting to a Server over the Console
--------------------------------------------
 
- - Open the console and type in the following command:
-
-    connect <ip/host>:<port>#<player-no>
+ - open the console and type in the following command:
+  
+    ]connect <ip/host>:<port>#<player-no>
 
 
 4. Playing Internet-Games
---------------------------
 
- - Since OpenTTD 0.3.5 the network protocol has been rewritten and is very stable, even over slow connections.
-
- - Servers with a red dot behind it have a different version then you have. You will not be able to join those servers.
-
- - Servers with a yellow dot behind it have NewGRFs that you do not have. You will not be able to join those servers.
-
- - It can happen that a connection is that slow, or you have that many clients connected to your server, that your clients start to loose their connection. Some things you can do about it:
-
-   - net_frame_freq:
-      change it in console with: net_frame_freq = <number>
-     the number should be between the 0 and 10, not much higher. It indicates the delay between clicking and showing up. The higher, the more you notice it, but the less bandwidth you use.
-     A good value for Internet-games is 2 or 3.
-
-   - net_sync_freq:
-      change it in console with: net_sync_freq = <number>
-     the number should be between the 50 and 1000, not much lower, not much higer. It indicates the time between sync-frames. A sync-frame is a frame which checks if all clients are still in sync. When the value it too high, clients can desync in 1960, but the server detects it in 1970. Not really handy. The lower the value, the more bandwidth it uses.
-
-   NB: changing net_frame_freq has more effect on the bandwidth then net_sync_freq. You should never change net_sync_freq!
-
-
-5. Tips for servers
---------------------
-
- - You can launch a dedicated server by adding -D as parameter
- - In UNIX like systems, you can fork your dedicated server by adding -f as parameter
-
- - You can automaticly clean companies that do not have a client connected to them, for, let's say,
-      3 years. You can do this via: 'set autoclean_companies' and 'set autoclean_protected' and
-      'set autoclean_unprotected'. Unprotected removes a password from a company when it is
-      not used for more then the defined amount of months.
- - You can also do this manually via the console: 'reset_company'.
-    Both ways, the company will go bankrupt.
-
- - You can let your server automaticly restart a map when, let's say, year 2030 is reached.
-    See 'set restart_game_date' for detail.
- - If you want to be on the server-list, enable Advertising. To do this, select 'Internet (advertise)'
-    in the Start Server menu, or type in console: 'set server_advertise 1'.
-
- - You can protect your server with a password via the console: 'set server_pw', or via the
-    Start Server menu.
-
- - When you have many clients connected to your server via Internet, watch your bandwidth (if
-    you have any limit on it, set by your ISP). 1 client uses +/- 3 kb/s up and down. To decrease
-    this amount, set 'net_frame_freq' to 1 for example. This will reduce it to 1.5 kb/s per client.
-
-
-6. Some useful things
-----------------------
-
- - You can protect your company so nobody else can join uninvited. To do this, check your Company Screen
-
- - You can give other players some money via the ClientList (under the 'head' in the mainbar).
-
- - You can chat with other players via ENTER or via SHIFT+T or via the ClientList
-
- - Servers can now kick players, so don't make them use it!
-
- - From 0.3.5, desyncs should not happen anymore
-
- - From 0.3.5, patch-settings are also synced. You can now play without deleting openttd.cfg, and with, for example, extra large trains enabled.
-
-7. Troubleshooting
-------------------
-
- - My advertised server does not show up in the 'advertised server list' (servers.openttd.org)
-     Run openttd with the '-d net=2' parameter, as this will show whether it receives replies from the master server.
-     If it does not receive replies it is most likely that you need to configure your router to forward the OpenTTD ports 3979 (both TCP and UDP) to the computer that is hosting the game.
+ - since OpenTTD 0.3.4 you can also play internet games over higher latency connections.
+ - to do this the gameservers sync frequency should be highered to a decent value.
+   - open the console [on the server]
+   - type in the following command:
+   
+    ] *net_sync_freq = <4-80>
+    
+    default value: 4
+    
+   - this is lowering the sync frequency of the server and your game should be less laggy.
+   - this is a server variable: it has nothing to do with the clients
+   
+ - you can also change when the clients ready packet is sent if you still have lags.
+   - open the console
+   - type in the following command:
+   
+    ] *net_ready_ahead = <1-8>
+    
+    default value: 1
+    
+   - in that way your client is sending its "i am ready for next sync" a bit earlier
+     thats quite good for games where some players have higher latencies than the others.
+   - this is a client variable: it has nothing to do with the server
+ 
+ - to change the client timeout time
+   - open the console [on the server]
+   - type in the following command:
+   
+    ] *net_client_timeout = <30-x>
+    
+    default value: 300
+   
+   - warning: a too low value will disconnect your clients if they have a short lag
+   
+
