How cairngorm framework works internally

I had gone through many documents, no where mentioned how cairngorm framework works internally, means, how cairngorm Event, fron开发者_StackOverflow中文版tController, BusinessDelegate,ServiceLocator,Commands works and why we are extending or implementing cairngorm class like ICommand, IResponder and cairngormEvent.

Thanks, Ravi

For the love of GOD, don't use Cairngorm (2) as a framework. Use either RobotLegs or Parsley. Both of which has awesome documentation and a very active community.
