    longDescription = ''
      Sawfish is an extensible window manager using a Lisp-based scripting
      language. Its policy is very minimal compared to most window managers. Its
      aim is simply to manage windows in the most flexible and attractive manner
      possible. All high-level WM functions are implemented in Lisp for future
      extensibility or redefinition.
