[cfe-dev] Generate a header file from a source file with clang

[Philip Reames]

I hacked together a tool which did this a while back.  If you don't care 
about is handling the full power of C++, it's not that difficult.

Basically, run it through the parser, then perform walks over the AST.

Note: This assumes that the original code compiles cleanly _without_ 
including your newly generated header.

Note: I didn't use the 'plugin' mechanism.  So no comment on that part 
of the question.
