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.
cron-apt -V (return code: -15)
The config file --VERSION does not exist.
cron-apt --help (return code: 0)
USAGE: cron-apt [-i] [-s] [configfiles]
