OpenGL Spec Parsing

Hello, comrades!
Where i can find scripts for generate glext.h file from .spec files?
I found them in OSS opengl sample implementation, but may be I can get new version of scripts?

Yours, Oleg!

And I read this

The header is intended to be useful on other platforms than Linux, particularly Windows; please let us know (via feedback to forums) if it needs enhancement for use on another platform. The generator scripts and “.spec” files used in generating glext.h are also available.
