Yes, this is probably a better way of saying what I want to do.  In the
end, I do want to have something prebuilt that the users can just run.
There's no need to deploy anything else on the server.  I was hoping to
avoid extra coding, but I'm willing to look into this.  
Is there a way to have a custom classloader that doesn't use this plan
mechanism?  If I'm going to build custom code, I'd might as well write
this.  This would help me avoid moving lib files around.  One problem is
that these libraries are used for other command line scripts.

I would like to stick with a released version for stability reasons.  I
currently have 2.0.
