+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.
