usage: opengl-update <GL implementation>
note:
This utility switch between OpenGL implementations. Currently there
are two supported implementations, namely "xfree" and "nvidia", the
implementations for XFree86 and the NVidia drivers respectively.
examples:
opengl-update xfree
This will setup things to use libGL.so from XFree86
opengl-update nvidia
This will setup things to use libGL.so from the NVidia drivers.
