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.
runlevel -V (return code: 1)
runlevel: unrecognized option '--version'
runlevel --help (return code: 0)
Prints the previous and current runlevel of the init system.
--help Show this help
