Very nice work Peter. Thank you. Very good idea.

I made a few small edits and checked them in.
* Regarding BaseGLUT depending only upon BaseGL: in real life, libglut
depends on both libglu and libgl. So, anyone using BaseGLUT will need
those libs installed anyway. In C code, glut.h #includes glu.h and
gl.h. I'm not sure why we'd list BaseGLUT as depending only upon GL
rather than both GLU and GL.
BTW, as a ruby-opengl user, I'd expect that if I wanted to use
BaseGLUT, I'd need to write my first lines as:
in that order.
* What does this one mean:
| * The project will make a development environment suitable for porting to
| other platforms available via checkout from the svn repository
* I like your idea of keeping the 3 modules in a parent "GL"
directory. I also like the idea of following Ruby conventions of
keeping the file names lowercase. Further, I'm also warming up to the
idea of having the module names first-letter-only-capitalized:
Gl.glFooBar( Gl::GL_FOO_BAR )
glFooBar( GL_FOO_BAR )
My reasons being:
A. There's good contrast between the three different capitalizations.
B. It follows standard Ruby naming conventions.
C. IMO, GL.glFoo and GL::GL_FOO doesn't look any better than Gl.glFoo
and Gl::GL_FOO. Most folks would probably just use the `include Gl`
and so wouldn't see it anyway.
* Regarding tracking of different versions of GL and GLUT, 0.32pre2
already has Yoshi's conditional stuff in it for older versions. Anyone
know how difficult it would be with SWIG to get it to do the same sort
Peter -- have you formed an opinion on the SWIG issue yet?
