The code is all documented using javadoc comments. The package description was automatically created using the javadoc command.

The only thing I had to do besides the commenting in the code was write a simple general description file called package.html to generate a few general comments, which it incorporated into the pages it generated. The javadoc command does the rest of the work. I think it is pretty impressive.
