    <para>If the distribution and/or use of the Program is restricted

    in certain countries either by patents or by copyrighted

    interfaces, the original copyright holder who places the Program

    under this License may add an explicit geographical distribution

    limitation excluding those countries, so that distribution is

    permitted only in or among countries not thus excluded.  In such

    case, this License incorporates the limitation as if written in

    the body of this License.</para>
