[cfe-dev] Clang beginner - how to parse multiple files?

[Yaakov Davis]

I have a c++ application which I wish to convert to C#.
I can figure out some basic transformation rules which will do most of the
work (wrap static constants and functions, expand macros and typedefs,
remove pointers, etc.), then I'll do the rest by hand.

Where are the ClangTool and CompilationDatabase classes defined? I was
unable to locate them in the trunk.
