    <para>
      <application>Qt</application> is a cross-platform application
      framework that is widely used for developing application software
      with a graphical user interface (GUI) (in which cases Qt is classified
      as a widget toolkit), and also used for developing non-GUI programs such
      as command-line tools and consoles for servers. One of the major users
      of <application>Qt</application> is <application>KDE</application>.

        If <application>Qt</application> is being reinstalled, run the
        following commands from a console or non-Qt based window manager.
        It overwrites <application>Qt</application> libraries that should
