    <para>

      You may copy and distribute the Program (or a work based on it,

      under Section 2) in object code or executable form under the

      terms of Sections 1 and 2 above provided that you also do one of

      the following:

    <orderedlist numeration="loweralpha">

        <listitem>

            <para>

              Accompany it with the complete corresponding

              machine-readable source code, which must be distributed

              under the terms of Sections 1 and 2 above on a medium

              customarily used for software interchange; or,

            </para>

        </listitem>

        <listitem>

            <para>

              Accompany it with a written offer, valid for at least

              three years, to give any third party, for a charge no

              more than your cost of physically performing source

              distribution, a complete machine-readable copy of the

              corresponding source code, to be distributed under the

              terms of Sections 1 and 2 above on a medium customarily

              used for software interchange; or,

            </para>

            <para>

              Accompany it with the information you received as to the

              offer to distribute corresponding source code.  (This

              alternative is allowed only for noncommercial

              distribution and only if you received the program in

              object code or executable form with such an offer, in

              accord with Subsection b above.)

    <para>The source code for a work means the preferred form of the

    work for making modifications to it.  For an executable work,

    complete source code means all the source code for all modules it

    contains, plus any associated interface definition files, plus the

    scripts used to control compilation and installation of the

    executable.  However, as a special exception, the source code

    distributed need not include anything that is normally distributed

    (in either source or binary form) with the major components

    (compiler, kernel, and so on) of the operating system on which the

    executable runs, unless that component itself accompanies the

    executable.</para>

    <para>If distribution of executable or object code is made by

    offering access to copy from a designated place, then offering

    equivalent access to copy the source code from the same place

    counts as distribution of the source code, even though third

    parties are not compelled to copy the source along with the object

    code.</para>
