EPF is a PHP Framework based on the concept that any application can be considered as a model that the user manipulates.

It uses MVC components. The model is accessed using RESTfull controllers, and views creates the user interface.

The framework entry point (EPF) uses EPF::SAPI components, those are responsible of handling the different PHP SAPIs used to access the application. They create controllers (EPF::Controller) and views (EPF::View), and associate them with the user created EPF::Model. Communication between all those elements is done with messages (EPF::Message).
