      If GTK+-3 or GTK+-2 are installed and

      for GTK+-3 or GTK+-2 will be installed.  As the &root; user,
      update a cache file of GTK+-3 or GTK+-2 so the GTK-based applications
      can find the newly installed IM module and use ibus as an input

      The command above updates the cache file for GTK+-3.  For GTK+-2,
