OpenGL functions documents

Where can I find a list of complete (or most of) OpenGL functions with belief description?
Thank you for your help.

I often find useful to go read the OpenGL manpages .
Sometimes delighting, especially for beginners.

I personally think I don't need everything other than this and the extension registry 90% of the time.
