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.
iptables-xml -V (return code: -15)
iptables-xml: unrecognized option '--version'
iptables-xml --help (return code: 1)
Usage: iptables-xml [-c] [-v] [-h]
[ --verbose ]
[ --help ]
