Bruce has forgotten which flavor, since you can either produce shell
script or a binary option processing "partner", a la:
opts=`${0}-opts ${1+"$@"}`
eval "$opts"
case "X${OPTION_CT}" in
X ) exit 1 ;;
X0 ) : ;;
* ) shift ${OPTION_CT} ;;
esac
or source or auto-edit in the generated script:
. ${0}-opts.sh ${1+"$@"}

That is done with a companion binary, but I don't know if I did that
for the emitted shell script. It would be reasonable to check the
minimum count/must-set status and emit appropriate code. I am
certain I haven't done it for "must-set", I might have for "min = 1".
"must-set" is only 6 or 7 years old.

That is the way to go. Is it actually implemented? That is a completely
different question. Since "file" arguments are something from the last
few years and I haven't done much with shell script stuff for close to a
decade, (Parts of makeshell.c file havn't been touched in 14 years. :)
I'm pretty sure that no verifications get inserted into the script.
If you are willing and able to have a binary option parser program,
you'd get more consistency and easier support. Otherwise, for fastest
support, you'd be most welcome to fiddle the code in autoopts/makeshell.c
and the various strings it uses in autoopts/ao-strs.def.

I'd be thanking -you-! :) Cheers - Bruc
