We are reaching out to technical users who are interested in contributing to the Shumway implementation in these five areas:
1. Core. This module includes the main file format parser, the rasterizer, and event system.
2. AVM1. JavaScript interpreter for ActionScript version 1 and version 2 bytecode.
3. AVM2. JavaScript interpreter and JIT compiler for ActionScript version 3 bytecode.
4. Browser Integration handles the glue between the web browser and the Shumway runtime.
5. Testing/Demos. Add good demo and test files/links to Shumway.
