Adobe® Flex ™ becomes OpenSource !!!

Adobe announces plans to open Flex source code under the Mozilla Public License (MPL). This includes not only the ActionScript sources of the Flex SDK components that were available as source code in the SDK, but also includes the Java sources for ActionScript and MXML compilers, the ActionScript debugger and the main ActionScript libraries of the

Flex SDK. The SDK contains all the components necessary for creating Flex Applications that run in any browser on Mac OS X, Windows, and Linux.
