+===========
+SDL on OS/2
+===========
+
+Last updated on Oct 02, 2005.
+
+
+1. How to compile?
+------------------
+
+To compile this, you'll need the followings installed:
+- The OS/2 Developer's Toolkit
+- The OpenWatcom compiler 
+  (http://www.openwatcom.org)
+- The FSLib library
+  (ftp://ftp.netlabs.org/pub/SDL)
+
+Please edit the second, fourth and fifth lines of setvars.cmd file
+to set the folders where the toolkit, the OW compiler and the FSLib are. 
+You won't need NASM yet (The Netwide Assembler), you can leave that line.
+Run setvars.cmd, and you should get a shell in which you can
+compile SDL.
+
+Check the "Watcom.mif" file. This is the file which is included by all the
+Watcom makefiles, so changes here will affect the whole build process.
+There is a line in there which determines if the resulting SDL.DLL will be
+a 'debug' or a 'release' build. The 'debug' version is full of printf()'s,
+so if something goes wrong, its output can help a lot for debugging.
+
+Then go to the 'src' folder, and run "wmake -f makefile.wat".
+This should create the SDL.DLL and the corresponding SDL.LIB file there.
+
+To test applications, it's a good idea to use the 'debug' build of SDL, and
+redirect the standard output and standard error output to files, to see what
+happens internally in SDL.
+(like: testsprite >stdout.txt 2>stderr.txt)
+
+To rebuild SDL, use the following commands in 'src' folder:
+wmake -f makefile.wat clean
+wmake -f makefile.wat
+
+
+
+2. How to compile the testapps?
+-------------------------------
+
+Once you have SDL.DLL compiled, navigate into the 'test' folder, copy in there
+the newly built SDL.DLL, and copy in there FSLib.DLL.
+
+Then run "wmake -f makefile.wat" in there to compile some of the testapps.
+
+
+
+3. What is missing?
+-------------------
+
+The following things are missing from this SDL implementation:
+- MMX, SSE and 3DNOW! optimized video blitters?
+- HW Video surfaces
+- OpenGL support
+
+
+
+4. Special Keys / Full-Screen support
+-------------------------------------
+
+There are two special hot-keys implemented:
+- Alt+Home switches between fullscreen and windowed mode
+- Alt+End simulates closing the window (can be used as a Panic key)
+Only the LEFT Alt key will work.
+
+
+
+5. Joysticks on SDL/2
+---------------------
+
+The Joystick detection only works for standard joysticks (2 buttons, 2 axes
+and the like). Therefore, if you use a non-standard joystick, you should
+specify its features in the SDL_OS2_JOYSTICK environment variable in a batch
+file or CONFIG.SYS, so SDL applications can provide full capability to your
+device. The syntax is:
+
+SET SDL_OS2_JOYSTICK=[JOYSTICK_NAME] [AXES] [BUTTONS] [HATS] [BALLS]
+
+So, it you have a Gravis GamePad with 4 axes, 2 buttons, 2 hats and 0 balls,
+the line should be:
+
+SET SDL_OS2_JOYSTICK=Gravis_GamePad 4 2 2 0
+
+If you want to add spaces in your joystick name, just surround it with
+quotes or double-quotes:
+
+SET SDL_OS2_JOYSTICK='Gravis GamePad' 4 2 2 0
+
+or
+
+SET SDL_OS2_JOYSTICK="Gravis GamePad" 4 2 2 0
+
+   Notive However that Balls and Hats are not supported under OS/2, and the
+value will be ignored... but it is wise to define these correctly because 
+in the future those can be supported.
+   Also the number of buttons is limited to 2 when using two joysticks,
+4 when using one joystick with 4 axes, 6 when using a joystick with 3 axes
+and 8 when using a joystick with 2 axes. Notice however these are limitations 
+of the Joystick Port hardware, not OS/2.
+
+
+
+6. Next steps...
+----------------
+
+Things to do:
+- Implement missing stuffs (look for 'TODO' string in source code!)
+- Finish video driver (the 'wincommon' can be a good example for missing
+  things like application icon and so on...)
+- Enable MMX/SSE/SSE2 acceleration functions
+- Rewrite CDROM support using DOS Ioctl for better support.
