Note: help and version output are generated by a naïve script which tries a few variants of
<command> --help, <command> -h etc. to find the command's help and version info.
Sometimes it gets lucky, sometimes it doesn't; if the output below looks wrong, it probably is.
ipmaddr -V (return code: 5)

Usage: ipmaddr [ add | del ] MULTIADDR dev STRING
