[cfe-dev] Hacking advice

[Jeff Kunkel]

The overall goal would be
1: parse the names, return types, and parameters of functions with a given
context like a namespace, class, struct or global scope.
2: parse classes, structs, enums, etc for the name, internal objects,
members, member methods, virtual overrides, inheritance, etc.
3: The final output would be the boost::python C++ code wrapper with as
descriptive an interface as the C++ class itself.

Thanks,
Jeff Kunkel
