     DESCRIPTION
          This documentation is no longer being maintained and may be
          inaccurate or incomplete.  The Texinfo documentation is now
          the authoritative source.

          prints the command line arguments, separated by spaces and
          followed by a newline, forever until it is killed.  If no
          arguments are given, it prints `y' followed by a newline
          forever until killed.

          When GNU yes is invoked with exactly one argument, the
          following options are recognized:

          --help
               Print a usage message on standard output and exit
               successfully.

               successfully.
