/// A base class for defining a ClangTidy check based on a `RewriteRule`.
//
// For example, given a rule `MyCheckAsRewriteRule`, one can define a tidy check
// as follows:
//
// class MyCheck : public TransformerClangTidyCheck {
//  public:
//   MyCheck(StringRef Name, ClangTidyContext *Context)
//       : TransformerClangTidyCheck(MyCheckAsRewriteRule, Name, Context) {}
// };
//
// `TransformerClangTidyCheck` recognizes this clang-tidy option:
//
//  * IncludeStyle. A string specifying which file naming convention is used by
//      the source code, 'llvm' or 'google'.  Default is 'llvm'. The naming
//      convention influences how canonical headers are distinguished from other
//      includes.
