20/// The check supports these options:
21/// - `HeaderFileExtensions`: a semicolon-separated list of filename
22/// extensions of header files (The filename extension should not contain
23/// "." prefix). ";h;hh;hpp;hxx" by default.
24///
25/// For extension-less header files, using an empty string or leaving an
26/// empty string between ";" if there are other filename extensions.
