This project is intended to help Flex and AS3 application developers, that use the PureMVC framework for AS3 - simple or multicore version - by providing them deep insights on what happens at the framework level: Notifications, Commands, Mediators and Proxies. PureMVC is a highly recognized MVC framework, that has also many portages in various languages, and that’s now quite widely in Flex applications, though not as much as Cairngorm.
