We’ve been working for about 8 months on-and-off on a project we’re really excited about: Mercurial, re-written in Ruby from the ground up. It’s called Amp, and it’s out in beta form!

We didn’t just rewrite it for fun though - there’s a lot of nifty features. The command system is what we’re most proud of right now, and we’ve got a lot of great ideas. Also, we need contributors, so come help out!
