About "rewriting" and ObjC support

Does someone have a high-level overview of what all the ObjC rewriting
commits recently are about?

Unrelatedly, supposing one wanted to alter every class and method name
in an ObjC program, would clang's rewriting support be an appropriate
way to do this?

At this point, we're just playing around with it (hence the name "-rewrite-test") to exercise the rewriting library.

The rewriting library is designed to support refactoring and code modification transformations.
