I've learned to deal with that... because I happen to be just like that ;-)

I think you're right in that doing file parsing is the way to do that. I was
playing with that yesterday ;-)

generating the docs with HDRSCAN and a target. BUt I have a question for
How do you consider the comment "#" style of documentation a better
