in Rails3 beta 4 where is the code that gets executed when you type 'rails server'?

I'm tracing my way through the source code and can't seem to find where the command "rails server" would be for a generated app. Where is it? Also is there some way 开发者_StackOverflow社区I can track down these things in the future?

In Rails 2 there was the script/server ruby script local to an application. In Rails 3, it appears they detect when they are inside a rails application path and have global scripts for all applications.

If your ruby install location was /ruby191, it would be in: /ruby191/lib/ruby/gems/1.9.1/gems/railties-3.0.0.beta4/lib/rails/commands/server.rb
