  ign msg [options]

Options:

  -i [ --info ] arg     Get info about the specified message type.
  -l [ --list ]         List all topics.
  -h [ --help ]              Print this help message.
  --force-version <VERSION>  Use a specific library version.
  --versions                 Show the available versions.
    -h "Print this help message,
        --help",
    -l, --list                       Print all message types
    -i, --info msg                   Print information about a message
