11 // While single translation unit refactorings are supported via the Rewriter,
12 // when refactoring multiple translation units changes must be stored in a
13 // SourceManager independent form, duplicate changes need to be removed, and
14 // all changes must be applied at once at the end of the refactoring so that
15 // the code is always parseable.
