140Mesa's directory tree has been overhauled.
141Things are better organized now with some thought toward future needs.

143<p>
144In CVS, the latest Mesa 5.1 development code is now rooted under the
145<b>Mesa-newtree/</b> directory.  The old top-level <b>Mesa/</b> directory
146holds the Mesa 5.0.x code which will be abandoned at some point.

706<pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
707US$10,000 to the Mesa project to support its continuing development.
708Mesa is a free implementation of the OpenGL 3D graphics library and id's
709newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
710
711The donation will go to Keith Whitwell, who has been optimizing Mesa to
712improve performance on 3d hardware.  Thanks to Keith's work, many
713applications using Mesa 3.1 will see a dramatic performance increase
714over Mesa 3.0.  The donation will allow Keith to continue working on
715Mesa full time for some time to come.
