  -p, --protocol[=ID]        Message protocol id (default 1)
  -r, --repeat[=COUNT]       Repeat the output COUNT (default 3) times
  -t, --time[=MICROSECS]     Override default protocol pulse timing

  -?, --help                 Give this help list
      --usage                Give a short usage message

  (e.g. cape_universal + config-pin p8.11 pruout)
  Connect P8_11 to <DATA> on a cheap 433Mhz transmitter module
