GlCommands Feature in Md2 files

Two questions
1-
Anyone can tell me what are the GlCommands structure stord in a MD2 file?
What is the purpose of that?

2-
Is there an information stored in MD2 files that give Material values? (Shininess, Specular color etc…)

Thanks for your help.

I could answer those questions. But I’ll do one better and point you to http://www.wotsit.org
Go there and do a search for md2.

Thank you.
