The help system works again in the latest builds. You can call help on any function exported by a module and get a description of the function built from its comment docs.
This only works for builds. I revamped the build system a couple days ago. Parts of the build process require java (for YUICompressor) and Python's docutils (for converting the JavaScript docs from RST to HTML). Everything else, like Python, Bash, and Gzip, are pretty much on every Unix system. Windows does need to be addressed at some point. The next step is to create a package management system. The current build includes 241 modules that I've created (some) or ported (most).
The build process does a lot of work that is required for any real production deployment. It creates the documentation, glossary, help files, and YUI compresses, bundles, and gzips all of the content. It would be good to get some feedback on usability.
