Stealth is a Software Development Kit, a set of code and tools to help programmers build beautifully functional applications in Flash. Reflecting the strengths of the Flash Platform this devkit was designed to be small, fast, graphic-rich, and work everywhere. So it's perfect for mobile apps and games. And it works in everyone's favorite tools, like Flash Professional or Flash Builder, using ActionScript 3 or even MXML!
