Window Maker is a X11 window manager which emulates the look and feel of the
NeXTSTEP (TM) graphical user interface. It is relatively fast, feature rich and
easy to configure and use. Window Maker is part of the official GNU project,
which means that Window Maker can interoperate with other GNU projects, such as
Window Maker allows users to switch themes 'on the fly,' to place favorite
applications on either an application dock, similar to AfterStep's Wharf or on
a workspace dock, a 'clip' which extends the application dock's usefulness.
