Subject Re: hotswap

When you say "scared", I hope the code didn't look that bad! (I mean, I thought
you might be talking about the power it could unleash).
No, we don't use it for production at all. Yes, we use it for development only.
I like that I can edit in Vim and invoke an ant target to compile and hotswap
my changes into the app. When I don't actually need a debugger and don't want
to fire up Eclipse, I use this instead.
I'd be happy to attach whatever license is required.
