-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 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.
-
-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

+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:

+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

+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.

+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:

---------------------------------------------
-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://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 8\VC" is your location of Visual C.
-If you are compiling for an x64 system, use the include\ and lib\ directories

-
-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'

+Notes about DirectMusic driver for Win32
+----------------------------------------
+
+If compiling under MinGW32, you require the DirectX 7.0 files for MinGW32, available from
+http://alleg.sourceforge.net/files/dx70_mgw.zip.
+
+If compiling under MSVC 6.0, you require the equivalent for MSVC, available from
+http://alleg.sourceforge.net/files/dx70_min.zip. MSVC 7.0/7.1 include header files that
+are recent enough.
+
+If you do not want to compile the DirectMusic driver, undefine WIN32_ENABLE_DIRECTMUSIC_SUPPORT
+in stdafx.h.
+
+Bugs, etc
+---------
+
+- The volume control doesn't work properly. I'll fix this soon.

-------------------
-
- - 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.
