This directory contains an OpenGL interface.  Layered upon this
interface are a GTK and Common Graphics (Windows-only) veneer.  Read
about them here in the files:

  * cggl/doc.txt
  * gtkgl/doc.txt

The files in the following directories were automatically generated:

  win32-1.1/	OpenGL 1.1 on Windows 2000
  linux-1.2/	OpenGL 1.2 on Red Hat 7.3
  linux-1.3/	OpenGL 1.3 on Red Hat 9.0

The files were generated with SWIG 1.3.22 (from www.swig.org).  If you
want to know more about this see the `Makefile'.

To run the teapot demo on Windows, start up the IDE and evaluate:

        (load "sys:opengl;cggl;load.cl")
        (red-teapot)

To run the GTK teapot demo on Linux/UNIX, start up Lisp and evaluate:

        (load "sys:opengl;gtkgl;load.cl")
	(red-teapot)

    The default OpenGL version is 1.2.   If you are running on a
    system with OpenGL 1.3, then edit opengl/gtkgl/load.cl and change
    the line

        (load (compile-file (merge-pathnames "../linux-1.2/opengl.cl"

    to

        (load (compile-file (merge-pathnames "../linux-1.3/opengl.cl"
