+/// The check supports these options:
+///   - `UseHeaderFileExtension`: Whether to use file extension to distinguish
+///     header files. True by default.
+///   - `HeaderFileExtensions`: a comma-separated list of filename extensions of
+///     header files (The filename extension should not contain "." prefix).
+///     ",h,hh,hpp,hxx" by default.
+///     For extension-less header files, using an empty string or leaving an
+///     empty string between "," if there are other filename extensions.
