-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.

+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
-
+'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.

+This is a guide to compile strgen on gcc

+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
+strgen/strgen lang/english.txt
+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

-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

-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.
+Due to complexities in my set-up, I actually used the Win32 version

+----------------------------------------
+
+The project file uses a bit of a hack to find out the SVN revision number and

+(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

-; Example file for the OpenTTD Base Graphics replacement sets.
-; This file consists of basically two different parts:
-;  * metadata
-;  * information about the files
-;
-; Metadata contains information about the name, version and palette
-; of the graphics set.
-;
-; == Getting started ==
-; - you can't add comments after values
-; - you have to fill the MD5 checksum for each file
-; - you may not miss any of the metadata or files items
-; - `openttd -h` lists all graphics replacements sets it found to be correct
-; - `openttd -d grf=1` shows warnings/errors when parsing an .obg file
-; - `openttd -I <name>` starts OpenTTD with the given set (case sensitive)
-; - adding `graphicsset = <name>` to the misc section of openttd.cfg makes
-;   OpenTTD start with that graphics set by default
-; - there is a command line tool for all platforms called md5sum that can
-;   create the MD5 checksum you need.
-; - all files specified in this file are search relatively to the path where
-;   this file is found, i.e. if the graphics files are in a subdir you have
-;   to add that subdir to the names in this file to! It will NOT search for
-;   a file named like specified in here.

-; the version of this graphics set (read as single integer)
-version      = 0
-; a fairly short description of the set
-description  = foo
-; palette used by the set; either DOS or Windows
-palette      = DOS

-; The md5s section lists the MD5 checksum for the files that replace them.
