      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.
