I try to come up with the /usr/src doxygen target first.

Sounds fine to me. One directory per subsystem if we go the split-up way.

I'm not sure the subdirectory builds are that simple to implement in a  
generic fashion (I have to play around with some ideas here...).  
Adding a target by hand to each interesting subdirectory is easy.

I think provides a  
good start (until someone writes doxygen_style(9) :-) ).

A FAQ is available at  
and contains a list  
of all doxygen recognized documentation-commands.
