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".
