OpenGL extension registry files + converter scripts to generate
extension interface headers.

Files associated with the OpenGL extension registry.
THESE FILES MUST NOT BE MODIFIED EXCEPT BY SGI'S ARB REPRESENTATIVE.

    gl.spec	    - GL function registry
    enum.spec	    - GL enumerant registry
    glx.spec	    - GLX function registry (incomplete - see glxext.spec)
    glxenum.spec    - GLX enumerant registry
    glu.spec	    - GLU function registry
    enumglu.spec    - GLU enumerant registry (should be renamed)
    wgl.spec	    - WGL function registry (incomplete, out of date)
    wglenum.spec    - WGL enumerant registry (based on master Microsoft registry)

Derivative files used to construct *ext.h extension interface headers
    and related development stuff.

THESE FILES MUST REMAIN SYNCHRONIZED WITH THE REGISTRY FILES ABOVE.

    enumext.spec    - GL enumerants in extension order
    glxenumext.spec - GLX enumerants in extension order
    wglenumext.spec - WGL enumerants in extension order

    glxext.spec     - GLX extension functions in extension order
    wglext.spec     - WGL extension functions in extension order

Scripts used to construct extension interface headers:

    glextenum.pl    - Convert enum.spec files into C headers
    glexttemplate.pl- Convert gl.spec files into C headers
    glext.pl	    - Assumble enumerants and functions into combined header

    {gl,glx,wgl}.tm - Typemaps converting from specfile to C types
