great news. I have signed the mailing list.
We certainly want to collaborate, and a student (Gilberto Ribeiro) will be
involved on the
development of the spatial operators as part of his Master thesis.
If you need anything more from us, please let me know.

Basically, if you are familiar with Javadoc comments, you can use exactly the
same technique for Doxygen. It is also very flexible and supports other
doc-comment styles such as the QT style (which I'm not personally aware of) and
some of its own, custom options.
