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.
lockfile-remove -V (return code: 1)
lockfile-remove: unrecognized option '--version'
usage: lockfile-remove [--lock-name] file
lockfile-remove -h (return code: 1)
lockfile-remove: invalid option -- 'h'
usage: lockfile-remove [--lock-name] file
