Hi,
I am making a game using Ruby-SDL called Nebular Gauntlet and the game 
is working fairly well using SDL drawing, but I was thinking of trying 
to gain a couple extra FPS by using OpenGL to draw. However, I can not 
seem to find any tutorials or samples that could be useful and was 
wondering if anyone else could point me in the right direction (I can't 
even find any documentation for Ruby's OpenGL library).

Thanks,
Steven Davidovitz
