       Run  GNU  M4  on  the  FILES,  avoiding  useless  runs.  Output the traces if tracing, the frozen file if
       freezing, otherwise the expansion of the FILES.

       If some of the FILES are named 'FILE.m4f' they are considered to be M4 frozen files of all  the  previous
       files  (which  are  therefore  not  loaded).   If  'FILE.m4f'  is not found, then 'FILE.m4' will be used,
       together with all the previous files.

       Some files may be optional, i.e., will only be processed if found in the include path, but then must  end
       in '.m4?';  the question mark is not part of the actual file name.
