options handling when there are LOTS of options

Is there a way to make package options take a value, rather than simple binary (present/nonpresent) switches?  I've got a package with over 40 possible drivers. I think it would be a lot easier to take a comma-delimited string and pass it straight to configure since that's the kind of format it's expecting, than to construct such a string from bunches of individual options.  Especially since its configure already supports "all,!driver" syntax.


Thanks,
Tim
