* Documentation generator

* Google Code wiki documentation.
*
* This script is rather crappy. It does what it needs to do, but uses global
* variables and it might be a hard to read.
*
* I'm not sure if I care though. Maybe one day this can become a separate
* project
*
* To run this script, just execute on the command line. The script assumes
* it's in the standard bin/ directory.
