  21 <p>
  22 Mesa is a 3-D graphics library with an API which is very similar to
  23 that of <a href="https://www.opengl.org/">OpenGL</a><sup>[<a href="#trademark">1</a>]</sup>.
  24 To the extent that Mesa utilizes the OpenGL command syntax or state
  25 machine, it is being used with authorization from <a
  26 href="https://www.sgi.com/">Silicon Graphics,
  27 Inc.</a>(SGI). However, the author does not possess an OpenGL license
  28 from SGI, and makes no claim that Mesa is in any way a compatible
  29 replacement for OpenGL or associated with SGI. Those who want a
  30 licensed implementation of OpenGL should contact a licensed
  31 vendor.
  32 </p>
  33
  34 <p>
  35 Please do not refer to the library as <em>MesaGL</em> (for legal
  36 reasons). It's just <em>Mesa</em> or <em>The Mesa 3-D graphics
  37 library</em>.
