[HOpenGL] Re: GLUT copyright violation

[Ross Paterson]

There may be a way out of this mess without inventing convenient legal
theories.

The text you've used is also spread across the manpages included in
the glut tarball.  Assuming that makes the manpages part of libglut,
they would be covered by the permission Michael Weber mentioned:

	http://www.fifi.org/doc/glutg3-dev/copyright

so it should suffice to change the acknowledgement in GLUT.hs to say
that your docs are based on the manpages from libglut, by Mark J. Kilgard.
