ChicagoRuby.org: Multi-Level Ruby

In a short time frame Rails is moving from version 2.2, to 2.3, to (with the Merb merge) 3.0. In that same period Ruby will grow from version 1.8.7 to 1.9.1. How do you keep up? How do you run multiple versions of Ruby and Rails on the same machine?

We’ll discuss one multi-version method at our Feb 21, 2009 meeting. And if you have a few tips & tricks of your own, come prepared to share!
