Probably the best single piece of documentation with the module is the README file contained in the distribution. There are a few very simple examples about half way down.

Beyond that, the key to understanding how to use the module, is to understand the Win32 Permissions model. It is a very powerful, but also very complex beast. The book would probably be a good way to getting an understanding of the module and how to use it, but don't be surprised if it has to go into quite a lot of detail of the OS security model to do it.

Whilst you wait for the book to arrive, you could try the MS documentation....here is as good a starting point as any.

Good luck.
