Clang-cast is a clang tool that visits the clang AST to emit diagnostics about C style casts.
It classifies a C style cast as one that includes any combination of const/reinterpret/static casts,
one that can't be converted to a C++ cast, or a no-op cast. The tool can...

- Either warn or error on particular types of C-style casts listed above.
- Fix particular types of C-style casts listed above (in-place or in new files)
  - Can emit code that's -pedantic compliant (for e.x. VLA's are used in casting)
- Give a summary of statistics of C style casts in the translation unit.
- Warn on subtleties such as member-pointer casts of different classes and more.

The tool will stop at system headers and will not visit any headers if --no-includes is set.
