RobotLegs AS3.0 Application Development Framework
Robotlegs is an AS 3.0 micro-architecture (or call it framework) to use with your AS 3.0 or Flex Projects. Its just an extension of PureMVC and adds Dependency Injection to it. Didnt try it personally but says it reduces the amount of boilerplate code to be written to setup a PureMVC application. It also avoids Singletons and static constants from your projects. It supports Modules (It has to, as PureMVC does it).
