phpDocumentor call for help
If you’re looking for a worthwhile project to invest some spare time on (and perhaps add to your CV), phpDocumentor is it. It’s pretty much become the standard API doc tool for PHP and is an asset to everyone working with PHP.
Think the big thing it needs is unit tests, which would do alot to reduce the effort required to maintain it. If you do sign up for the mailing lists, best to take a “self starting” approach – calls for help of this kind usually mean someone already got too much to do.
