Bebox – Convention over configuration for puppet repositories

Bebox helps automating the provisioning of environments in which Ruby on Rails applications run, making easy to create new server setups every time.
Bebox’s main concern is the structure. It is generally a good idea to have conventions about how different source code files are placed and named and be able to use this to reduce the details required to understand a project while also providing automation in key places. These conventions may include things like: how to write puppet modules, how to integrate them into the projects, a directory structure for the projects, how to have a replicated “development/test” environment into virtual machines, etc.
