Re: [Jython-users] Anyone interested in helping on a Minecraft plugin project?

[Jim B. <jim...@py...>]

Paul,

I don't think this needs to be in a private email - threads work well
enough :), and this list is very low traffic.

Anyway, I'm back from vacation, and I should let you and Ben know that I
plan to work next on Clamp's support for Java annotations [1]. We need this
for a project using Spring annotations; that it supports Minecraft sounds
like a very nice bonus to me. I'm sure others will find this very
beneficial as well in their Jython usage.
