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.
dovecot --version (return code: 0)
dovecot --help (return code: 0)
Usage: dovecot [-F] [-c <config file>] [-p] [-n] [-a] [--help] [--version]
[--build-options] [--hostdomain] [reload] [stop]
