    # pyopengl takes the "name" (for us: the path) and tries to add a

    # list of possible files.

      PyOpenGL is the cross platform Python binding to OpenGL and
      related APIs.  The binding is created using the standard (in
      Python 2.5) ctypes library, and is provided under an extremely
      liberal BSD-style Open-Source license.
