      OptionList.strip_output("      How RDoc generates output depends on the output formatter being
      used, and on the options you give.

      - HTML output is normally produced into a number of separate files
        (one per class, module, and file, along with various indices). 
        These files will appear in the directory given by the --op
        option (doc/ by default).

      - XML output by default is written to standard output. If a
        --opname option is given, the output will instead be written
        to a file with that name in the output directory.

      - .chm files (Windows help files) are written in the --op directory.
        If an --opname parameter is present, that name is used, otherwise
        the file will be called rdoc.chm.

      For information on other RDoc options, use "rdoc --help".

          Files are parsed, and the information they contain
          collected, before any output is produced. This allows cross
          references between all files to be resolved. If a name is a
          directory, it is traversed. If no names are specified, all
          Ruby files in the current directory (and subdirectories) are
          processed.
