thanks for the tips!

Right, sounds good. So, a conditional 'make doxygen' rule in the top-level 
makefile?

Requiring this stuff is less of a burden if only maintainers need to deal 
with it.

I think the stumbling block is how to automate the runs. I don't mind 
reformatting all the comments and everything if the end product is really 
nice documentation...
