 Each of your application's modules must somehow implement LifeCycle. This is the minimum contract Booty needs in order to handle them. If you don't want to change your module dependencies, you can simply create anonymous LifeCycle classes that wrap them.

Chances are the behaviours themselves are already implemented in each module.
