<pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
US$10,000 to the Mesa project to support its continuing development.
Mesa is a free implementation of the OpenGL 3D graphics library and id's
newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
The donation will go to Keith Whitwell, who has been optimizing Mesa to
improve performance on 3d hardware. Thanks to Keith's work, many
applications using Mesa 3.1 will see a dramatic performance increase
over Mesa 3.0. The donation will allow Keith to continue working on
Mesa full time for some time to come.

This donation from John/id is very generous. Keith and I are very
grateful.
