Re: Anyone interested in helping on a Minecraft plugin project?

I have no problem holding hands here :) Sometimes I'm limited by time, but
such annotation support is now a work priority for me.

Given that Minecraft Jython support should be a very good demonstration of
what Clamp can do, and what we need to work on, I'm especially eager for
any and all guinea pigs. Let's do it!
