I haven't looked at the code in question, but I would
think the hardest part of this whole effort would be
providing the means for Ant to look up antlib version
info.  I'm actually fairly enthusiastic about using
the combination of existing arguments, mostly just
because of the number of requests I've seen for the
proliferation of arguments to Ant.  Surely one of the
existing committers could hook that up if you don't
want to tackle that part, Jeff... again, the rest is
the tricky part IMHO!
