# Funny thing: the OpenGL specs document all routines and
# constants *without* “gl” and “GL_” prefixes. It makes
# sense to add these in a language that does not have
# namespaces, like C. In Python, it does not. So this
# routine takes apart the contents of the PyOpenGL modules
# into separate pieces, with those unnecessary prefixes
# stripped. So instead of calling OpenGL.GL.glClear(), say,
# you can call gl.Clear(). And instead of referring to
# OpenGL.GL.GL_ACCUM, you can use GL.ACCUM instead.
# Much more concise all round.
