Actually, Matt himself recommends nms-sourceforge scripts rather than his own and he has some of their scripts on his site available for downloading. He also tells folks that his scripts were written when he was in high school, they aren';t very well-written and are terribly unsecure.

I give the guy credit for making the nms scripts available and realizing he was young when he started writing them. It's pretty amazing that so many people are still using his scripts after all this time!

Anyway... The instructions provided for the nms scripts are better than Matt's, the scripts are much more secure, and they've got more features than the originals. They're also smaller.
