      AfterStep is a window manager for the Unix X Window
      System. Originally based on the look and feel of the NeXTStep
      interface, it provides end users with a consistent, clean, and
      elegant desktop. The goal of AfterStep development is to provide
      for flexibility of desktop configuration, improving aestetics,
      and efficient use of system resources.
