Look at clang-tools-extra for examples. Rewriting in header files
happens out of the box, but if you want to check if your location is in
the "main" file or in a header file, you can use the source manager's
isInMainFile() for that purpose. See e.g.
tools/clang/tools/extra/clang-tidy/google/GlobalNamesInHeadersCheck.cpp:55
for a place where that happens.

Miklos
