id Software's Quake2 3.21+Changes by Steven Fuller <relnev@icculus.org>,

For this to be of any use, you _must_ own a copy of Quake 2.  The demo would
also work, but you might as well buy the full thing now.

These modifications are intended for Linux users, as I do not have have
access to other platforms.

Be sure to install SDL 1.2 (http://www.libsdl.org) if you want to use the
softsdl or sdlgl drivers, or the sdlquake2 binary.

You can change what drivers you wish to build by editing the Makefile and
changing the BUILD_ lines at the very top.

'make' will, by default, build both the debug and release files.
To build fully optimized binaries: make build_release
The resulting binaries are then put in releasei386.


To install the Quake2 gamedata:
-------------------------------
(installdir is wherever you want to install quake2, and cdromdir is wherever
you mount the Quake 2 CD-ROM)
1. copy <cdromdir>/Install/Data/baseq2/pak0.pak to <installdir>/baseq2/
2. copy <cdromdir>/Install/Data/baseq2/videos/ to <installdir>/baseq2/
   (optional)
3. Download q2-3.20-x86-full.exe from
   ftp://ftp.idsoftware.com/idstuff/quake2/ or a mirror site, and extract the 
   contents to a temporary directory (use unzip -L, as this is a standard zip
   file).
4. copy <q2-3.20-x86-full.exe temp directory>/baseq2/pak1.pak to
   <installdir>/baseq2/
5. copy <q2-3.20-x86-full.exe temp directory>/baseq2/pak2.pak to
   <installdir>/baseq2/
6. copy <q2-3.20-x86-full.exe temp directory>/baseq2/players/ to 
   <installdir>/baseq2/

To install this program:
------------------------
(builddir is either debugi386 or releasei386)
1. copy <builddir>/gamei386.so to <installdir>/baseq2/
2. copy <builddir>/ref_*.so to <installdir>
3. copy <builddir>/quake2 to <installdir>
4. copy <builddir>/sdlquake2 to <installdir> (optional)


To run:
-------
cd <installdir> && ./quake2
Or:
quake2 +set basedir <installdir>

/etc/quake2.conf is no longer needed; instead, the ref_*.so files are loaded
from basedir (basedir is "." by default, and can only be set at the command
line).

Configuration files and such are saved in ~/.quake2/, so <installdir> can be
made read-only or whatever.

WARNING: Please do not make quake2 or any of the libraries suid root!

NOTE: Save games will most likely not work across different versions or
builds (this is due to how savegames were stored).


Commonly used commands:
-----------------------
cd_nocd 0               // disable CD audio
s_initsound 0           // disable sound
_windowed_mouse 0       // disable mouse-grabbing
gl_ext_multitexture 0   // disable OpenGL Multitexturing (requires a
                           vid_restart)
vid_ref <driver>        // select a video driver (softx is the original
                           X11-only, softsdl is SDL software, sdlgl is 
                           SDL OpenGL)
vid_fullscreen 0        // disable fullscreen mode
vid_restart             // restart video driver
snd_restart             // restart sound driver
basedir <dir>           // point quake2 to where the data is
gl_driver <libGL.so>    // point quake2 to your libGL
