Doxygen

I downloaded a copy of Doxygen today. It parses C++ code for special comments in order to automatically produce documentation. I've used this before, but it's been awhile, and I'm rediscovering what a wonderful thing it is. All I have to do is update comments in the code every time I change the code, and my documentation is automatically kept up to date!
