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.
apt-listchanges -V (return code: 1)
apt-listchanges: option --version not recognized
apt-listchanges --help (return code: 0)
Usage: apt-listchanges [options] {--apt | filename.deb ...}
