So then you start moving it over.  In commons everything is broken out
component-wise, but this is nothing new.  Let's start talking about how
to go forward with whatever you/we feel should be in the commons.  I see
commons as a bunch of components, but I tend to NOT see a framework in

So let's get all Excalibur's and Avalon's utility code into commons,
then Excalibur still uses it, and commons doesn't have to rewrite
(although rewriting seems to be the jakarta way, IMHO).  Everybody
should win.  Right?
