    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.
