With EFL new API work, we are trying to provide a more unified view and namespace of EFL. The old weird namespace split should be turning into a cleaner logical one where EFL is the base of it. I am guessing there should be maybe 2 differents introduction. One for those who know about EFL legacy API and one for those who don't.
This should cover major new feature like Eo object model, binding generation, asynchronous by design and MVVM.
