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.
sync-available --version (return code: 0)
update-avail (dctrl-tools) 2.24
sync-available --help (return code: 0)
Usage:
/usr/sbin/sync-available
/usr/sbin/sync-available --version
/usr/sbin/sync-available --help
