Agilion Chef recipes, for use with librarian. Particularly useful for local development with vagrant.
To generate a new rails application from template simply execute (interactive):
rails new AppName -d postgresql -T --skip-bundle -m https://raw.github.com/AgilionApps/AgilionRecipes/master/rails_template.rb
This will create the application, set up vagrant and chef, boot the vm, provision the vm, and provide custom post-install steps.
