darkplaces (crossplatform Quake modification)

DarkPlaces is a gameplay modification and a source port engine based on the
computer game Quake.  It adds enhanced network code, with asynchronous delta
compression, a built in server browser, real-time lighting, and bump mapping.
It makes use of the OpenGL Shading Language and supports Ogg Vorbis.

By default the binaries will not be built from source, we will instead use
the supplied binaries.  if you wish to build your own binaries from source
them pass SOURCE=YES to the build.

The application launcher will launch the OpenGL version of Quake, however
if you would prefer it to launch the SDL version then pass SDL=YES to the
build.

Also the darkplaces game modifications are disabled by default to maintain
that "classic" look of the original quake.  To enable the modifications,
pass DPMOD=YES to the build.

*NOTE* DarkPlaces is only a game engine modification; you still need the
original quake *.pak game files to play quake.  See README.SLACKWARE for
more information on this.
