Has anybody used  Sawmill or know anything about it?

Here is what I got in an email

THE SAWMILL WINDOW MANAGER                 
        
Sawmill is a highly configurable window manager for Linux and several 
Unix flavors. Its major advantage over the Enlightenment window 
manager is its minimal system requirements. Thus, it can run on Linux 
machines that have slow processors and minimal memory. 

Sawmill is distributed under the terms of the GNU GPL license. You can 
find more information on Sawmill and download it from
