If a\n--opname option is given, the output will instead be written\nto a file with that name in the output directory.\n\n- .chm files (Windows help files) are written in the --op directory.\nIf an --opname parameter is present, that name is used, otherwise\nthe file will be called rdoc.chm.\n\nFor information on other RDoc options, use \"rdoc --help\".\n")
