Yes, that looks like a good start; thanks.  Obviously there's more
work to do (e.g., "$something", and most importantly modifying the
documentation and the rest of Autoconf to use it) but this is a good
way to go.

One minor comment; perhaps it'd be better to replace IFS='$2' with
IFS=$2 so that the user can use shell variables, apostrophes, etc.
