# Changelog:
# 0.2.8-1:   16/may/2005 by Eric Hameleers <alien@sox.homeip.net>
#            * Initial build.

# THIS PACKAGE WILL BE LINKED AGAINST YOUR OPENGL HARDWARE DRIVER.
# Change this next line when you're building on hardware that has no nvidia
# OpenGL driver installed, lke mine.
# That way, downloaders can see what OpenGL driver is supported by the
# binary package (think of ati or mesa as alternatives).
