Mesa is a 3-D graphics library with an API which is very similar to that of OpenGL*. The primary Mesa ftp site is ftp://mesa3d.sourceforge.net/pub/mesa3d/. Mesa is also mirrored at ftp://ftp.kddlabs.co.jp/.6/graphics/mesa/. As of version 2.3, Mesa is distributed in two pieces: main library code and demos. If you're upgrading from a previous version of Mesa or you're not interested in the demos you can just download the core Mesa archive file.
