> I meant porting existing tools to use it. You did that?

Please read before you write, even if you're busy. Andreas talked
about PlusTools in his post. Earlier this week, you specifically asked
for someone to ready this work for 3.9a, and that's exactly what I
did. See http://lists.squeakfoundation.org/pipermail/squeak-dev/2005-October/096020.html
and other mails surrounding the thread you started.
