Build call graph

[achorein]

Hi.

Is there a way to detect function calls in order to build the call graph ?

Well. There's always a way. The question is how much blood you want to spill to get it.
(Yeah, blood. Sed is dark magic).

Detecting command names in simple command lines should be doable. But I think it will not be trivial if you want to cover all the cases. If parameters can be removed from the call without confusing doxygen, I might give it a shot.
At least for top level commands. Nested calls might be more difficult.
