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.
mkindex --VERSION (return code: 0)
basename: unrecognized option '--VERSION'
Try 'basename --help' for more information.
mkindex --HELP (return code: 0)
basename: unrecognized option '--HELP'
Try 'basename --help' for more information.
