Padrino and Template Inheritance

Rango was the first framework supporting template inheritance in Ruby. Now thanks to the template-inheritance gem and its new Padrino adapter you can have all the inheritance goodies in Padrino!

Custom Gems in Gemfile

Switching between your custom libraries from your local directory and from RubyGems.org can be a real pain. Fortunately with Bundler it's getting much easier.
