Mesa is a 3-D graphics library with an API which is very similar to that
of OpenGL*.

The primary Mesa ftp site is iris.ssec.wisc.edu in the pub/Mesa directory.
Mesa is also mirrored on sunsite in the directory pub/packages/development
/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.
