    (description
     "Window Maker is an X11 window manager originally designed to provide
integration support for the GNUstep Desktop Environment.  In every way
possible, it reproduces the elegant look and feel of the NeXTSTEP user
interface.  It is fast, feature rich, easy to configure, and easy to use.")
