Hi Edson,

sure, but if nobody bothers to document this stuff it doesn't matter where the 
information is missing. The function that is exported from the module to the 
config script don't match exactly to the C function that lays behind it. So i 
think that showing users that information will only add confusion.

Well, its possible to provide general overview pages in doxygen. So it would 
be great to have such pages for every module that exports a API that is used 
from some other modules, for example. But this is at the moment not 
available.

Sure, for stable releases there will be no major changes. But i don't think 
that its worth all the work at the moment, especially given the state of the 
doxygen documentation for now. 

Lets look at an example, for the domainpolicy module: 
http://devel.openser.org/doxygen/dir_21e5e54a1f4057cbcc2546fbd3b342f3.html 

The information from the dependency graphs are that this modules depends on 
the parser (that is not configurable) and the DB interface. This information 
should also stated in the module documentation.

Cheers,

Henning
