What is Rango?
• Rack-based lightweight web framework
• As agnostic as possible
• The goal is to provide solid framework for building sites in Ruby. More robust than Sinatra, but smaller than Rails or Merb.

Features
• Ruby 1.9-only
• Provides generators, but don’t insist on a certain structure
• Code reloading by shotgun
• Bundler support
• Inspired by Django & Merb
Monday, November 30, 2009
• Django terminology (template, view = view, action in controller)
• Very flexible, you can use just whichever subset of Rango you want and it will work.
• No conventions, just recommendations

Boot Process
• Script init.rb should setup environment
• Work as runner: ./init.rb myscript.rb
• And as a console: ./init.rb -i
• Or both altogether: ./init.rb -i myscript.rb
• Start web server: ./config.ru
• Rewrite arguments: ./config.ru -s thin
