Ruby on Rails 2.0

Ruby on Rails 2.0 is out. This web development framework written in the Ruby dynamic programming language was the hot web dev topic for the past year or two (is it still a hot topic?).

It installs under both Microsoft Windows and Mac OS X. Mac OS X Tiger users note that the Rails website says that the version of Ruby provided with 10.4 is broken. The installation for both OSes requires RubyGems. So, be sure to install Ruby and RubyGems before attempting to install Rails 2.0. Oddly enough, I've only installed Rails under Linux. I'd be interested to hear your experience installing it under Windows or Mac OS X (especially 10.5 Leopard).
