 128 Mesa's directory tree has been overhauled.
 129 Things are better organized now with some thought toward future needs.
 130 </p>
 131 <p>
 132 In CVS, the latest Mesa 5.1 development code is now rooted under the
 133 <b>Mesa-newtree/</b> directory.  The old top-level <b>Mesa/</b> directory

 694 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
 695 US$10,000 to the Mesa project to support its continuing development.
 696 Mesa is a free implementation of the OpenGL 3D graphics library and id's
 697 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
 698
 699 The donation will go to Keith Whitwell, who has been optimizing Mesa to
 700 improve performance on 3d hardware.  Thanks to Keith's work, many
 701 applications using Mesa 3.1 will see a dramatic performance increase
 702 over Mesa 3.0.  The donation will allow Keith to continue working on
 703 Mesa full time for some time to come.
