 875 <p>
 876 Mesa's directory tree has been overhauled.
 877 Things are better organized now with some thought toward future needs.
 878 </p>
 879 <p>
 880 In CVS, the latest Mesa 5.1 development code is now rooted under the
 881 <b>Mesa-newtree/</b> directory.  The old top-level <b>Mesa/</b> directory
 882 holds the Mesa 5.0.x code which will be abandoned at some point.

1392 and OpenGL on Linux.</p>
1393 <p>While I'll be focused on Linux, the X Window System, and hardware acceleration,
1394 my work will continue to be open sourced and available to any other programmers who
1395 may want to contribute to it, or use it for other projects or platforms</p>

1431 <h2>May 13, 1999</h2>
1432 <pre>May 1999 - John Carmack of id Software, Inc. has made a donation of
1433 US$10,000 to the Mesa project to support its continuing development.
1434 Mesa is a free implementation of the OpenGL 3D graphics library and id's
1435 newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
1436
1437 The donation will go to Keith Whitwell, who has been optimizing Mesa to
1438 improve performance on 3d hardware.  Thanks to Keith's work, many
1439 applications using Mesa 3.1 will see a dramatic performance increase
1440 over Mesa 3.0.  The donation will allow Keith to continue working on
1441 Mesa full time for some time to come.
1442
1443 For more information about Mesa see www.mesa3d.org.  For more
1444 information about id Software, Inc. see www.idsoftware.com.

1448 This donation from John/id is very generous.  Keith and I are very
