现在还没有发布引擎代码，只有一个Demo，需要FlashPlayer9才能观看。

For the problem whether puting XFolder into core AsWing or not, we
have another idea, is a AsWing Extensions Collection page at
www.aswing.org
It's here:
http://aswing.wiki.adaptavist.com/display/AsWing/AsWing+Extensions

The idea is cool that some simple and useful component or any other
aswing useful classes and be shared here easily. This will not enlarge
the core AsWing library, but make people have more useful components.
We'll add some other useful classes later, And we encourage and hope
you to share your component very much!

Hope you like.
