Yes, I agree, actually.

Along these lines, I think we ought to reconsider making a single
barracuda.jar that combines the core and plankton stuff needed for
runtime...we can actually do this right now, using the jars.master taskdef -
it creates a single barracuda.jar, but it just leaves it in /lib-cvs, rather
than deploying inot /lib. We deploy all of our webapps using that single jar
just because fewer jars seems to make it easier to keep track of. I suspect
most people would probably prefer this (and we could still build the
barracuda-core.jar and plankton.jar in /lib-cvs...just not deploy them).

Anyway...just a thought...not a burning issue or anything.
