I think that AXIOMsys contains more than depsys, but I don't really know.  In
any case, depsys doesn't start the axiom interpreter, rather it gives you a
lisp prompt right away.  I guess that it's faster to start it.

I think so.  I also thought about trying this, because it might imply that we
could generate the interface from a distribution, too.
