Usage: #{opt.program_name} [options] [names...]

  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.

  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.
