Yes, I need this information to create a description of my source code as a 
graph, like a call graph, but with more information on the nodes. Every code 
line should be one node in the graph. If I have a function: I want to use the 
symbol name to link the function to another graph which describes it. And I need 
to identify the source file and the line to find the comments in the original 
code file.

Thanks for the hint. It will take me some time to look into that.
