There is an automatic parser in use (in python, actually) that was contributed and very cleverly converts in-game help to HTML. It's also scripted to check if the help file changes and update the website accordingly.
Unfortunately however we didn't catch a few items that we found since it went live:
1. angle brackets aren't converted to the proper HTML entities (> and < etc.)
2. some old help entries should not be listed (e.g. the
*delear entry at the top of the help list)
3. management versions of the help files aren't coming out as planned, making it a bit harder than usual to edit some of the existing help entries
There's also some fancy features we'd like to add (hot linking the "see also" footer in help entries; enabling keyword search across all help text; and others). Unfortunately I haven't had time to re-establish contact with the contributor to develop to parser further.
