Class Dependency Tool
I am looking for a tool (preferably open source) that, given the large amount of C / C ++ code, will generate a visual, or perhaps a graph of XML between classes (C ++) and / or files (C).
The idea would be that if you needed to convert your code to another language, you would like to get the lower level classes compiled first and build from there. So, first you need to determine what classes are there.
As far as I can tell, Doxygen doesn't have this capability, but I could be wrong.
Doxygen will do some pretty neat graphics.

I haven't used any open source tools for this, but the Rhapsody UML tool does it. They used to give a 30 day free trial to anyone who asked IBM just bought it, so I don't know if it's still there. http://www-01.ibm.com/software/awdtools/rhapsody/ It will change C / C ++ / Java / Ada.
