The documentation is pretty fragmentary, basically you need to create a 
ContextDefinition object:

http://pyopengl.sourceforge.net/pydoc/OpenGLContext.contextdefinition.html 
<http://pyopengl.sourceforge.net/pydoc/OpenGLContext.context.html>

if __name__ == "__main__":
     from OpenGLContext import contextdefinition
     TestContext.ContextMainLoop(
         definition = contextdefinition.ContextDefinition(
             size = (800,500 ),
         )
     )

which then is passed into the mainloop, which passes it into the 
context.Context() __init__ call.  The various GL features (bit depths 
and the like) are controlled the same way.  Each concrete Context 
sub-class (GLUTContext, PyGameContext, wxContext) then examines the 
ContextDefinition to set up the various features.  The 
ContextDefinitions can be populated from a ConfigParser, should you want 
to do that.

I'll try to add a bit of documentation about this stuff (and maybe make 
the API a little easier too) for the next OpenGLContext release.

Thanks,
Mike
