   6 // This widget is used to provide the management mode of ksetup.
   7 // There are two subwidgets; firstly a tree list showing all the
   8 // currently installed packages and secondly a display of the currently
   9 // selected package's properties.
  10 //
  11 // There are also some control buttons which allow the currently
  12 // selected package to be uninstalled or verified.
