  42 Execute command in all open screen(1) windows
  43
  44 For example, to send the command "hash -r" to all windows:
  45
  46   $progname hash -r
  47
  48 No " -- " before the command or quotes around the command are necessary,
  49 as the option parsing stops at the first non-option argument.
  50
  51 Usage: $progname [options] COMMAND
  52
  53 Options:
  54
  55   -h, --help
  56     Show this help.
  57   -q, --quiet
  58     Be more quiet. Can be repeated to increase silence.
  59   -v, --verbose
  60     Increase level of verbosity. Can be repeated.
  61   --version
  62     Print version information.
