Module: Lunetas::Bag

Defined in:
lib/lunetas/bag.rb

Overview

This is the module that keeps the register of all the Lunetas. It will add the classes to a register, and whenever rack receives a call, it delegates it. If Lunetas is not run as a stand alone rack application, then this module lacks of responsability, ie. Running as a Rails Metal.
