allow the OpenGL implementation to be overriden through the
OPENGL_DRIVER environment variable. If it is not set, we use the
implementation installed in the profile
/nix/var/nix/profiles/opengl, allowing easy late binding by the
user, e.g.,
$ nix-env -p /nix/var/nix/profiles/opengl -i nvidia-sys-opengl
might install the NVidia OpenGL implementation.
The code that does this is not specific to Quake 3: it has been
factored out into build-support/opengl/mesa-switch.sh. Presumably
any application that requires hardware-accelerated OpenGL needs it.

quake3/demo takes care of downloading and patching the required PAK
files. quake3/wrapper calls the Quake binary with a synthesised
directory of symlinks to activated PAK files. This should make it
easy to plug in the commercial PAKs, or third-party mods.

to work "out of the box" with hardware acceleration and either the
shareware or full PAK files. But with some hackery, I have gotten
it to work with both Mesa software rendering and NVidia hardware
rendering.
