    # 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.
