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.
nup -V (return code: 1)
nup: illegal option --version
usage: nup [-2|4|8] [-l] [-n] [-p paper]
nup --help (return code: 1)
nup: illegal option --help
usage: nup [-2|4|8] [-l] [-n] [-p paper]
