Razorqt is an advanced, easy-to-use, and fast desktop environment 
based on Qt technologies. It has been tailored for users who value 
simplicity, speed, and intuitive interface. Unlike desktop environments, 
Razorqt also works fine with weak machines.

Razorqt does not include a window manager.  While it can use fvwm2 or
kwin (included with Slackware), openbox is most often used by the 
upstream developers (and the one found most appealing here), so it is
strongly recommended.
