Remember that the script must parse the AC_PREREQ macro in  the target
package's configure.in file, and then choose the appropriate /usr/auto*
path.  How complicated (e.g. prone to breakage) should this logic be,
given a maze of /usr/autoconf-***/ directories?

I don't think this is really doable without fragility.  However, see
below.

Okay, now that's doable.  (Also, to force one or the other, just set the
path *yourself* to /usr/auto* -- then you'll never run these wrappers at
all.
