wine users - Jul 2008 - What is the new appwiz panel?

Hi, this sounds very interesting, but where can I find it and how does it work?
A search in the documentation/wiki/changelogs didnt turn up anything.

No idea, anyone? What is the purpose of a new feature, if you dont document it?
How can you let it be tested, how can anybody use it? This is strange.
