Disclaimer
Mesa is a 3-D graphics library with an API which is very similar to
that of OpenGL*
To the extent that Mesa utilizes the OpenGL command syntax or state
machine, it is being used with authorization from Silicon Graphics,
Inc.(SGI). However, the author does not possess an OpenGL license
from SGI, and makes no claim that Mesa is in any way a compatible
replacement for OpenGL or associated with SGI. Those who want a
licensed implementation of OpenGL should contact a licensed
vendor.
Please do not refer to the library as MesaGL (for legal
reasons). It's just Mesa or The Mesa 3-D graphics
library
* OpenGL is a trademark of Silicon Graphics Incorporated.

The Mesa distribution consists of several components. Different copyrights
and licenses apply to different components. For example, GLUT is copyrighted
by Mark Kilgard, some demo programs are copyrighted by SGI, some of the Mesa
device drivers are copyrighted by their authors. See below for a list of
Mesa's main components and the license for each.
The core Mesa library is licensed according to the terms of the MIT license.
This allows integration with the XFree86, Xorg and DRI projects.
