Well, you're going to want to look into Rack.

Really, you should just check out Sinatra. The whole 'framework' is like a thousand lines (or maybe two) of Ruby, and it's a pretty thin wrapper over Rack.

... any particular reason I'm at 0? Rack is the absolute minimum you're going to need to get Ruby to serve up dynamic pages, and Sinatra is an extremely minimal framework, to the point where it almost doesn't really deserve the term.
