    <para>You may modify your copy or copies of the Program or any
2ed941
    portion of it, thus forming a work based on the Program, and copy
2ed941
    and distribute such modifications or work under the terms of
2ed941
    Section 1 above, provided that you also meet all of these
2ed941
    conditions:</para>

            <para>If the modified program normally reads commands
2ed941
            interactively when run, you must cause it, when started
2ed941
            running for such interactive use in the most ordinary way,
2ed941
            to print or display an announcement including an
2ed941
            appropriate copyright notice and a notice that there is no
2ed941
            warranty (or else, saying that you provide a warranty) and
2ed941
            that users may redistribute the program under these
2ed941
            conditions, and telling the user how to view a copy of

                <para>
2ed941
                  If the Program itself is interactive but does not
2ed941
                  normally print such an announcement, your work based
2ed941
                  on the Program is not required to print an
2ed941
                  announcement.

2ed941
    
2ed941
    <para>These requirements apply to the modified work as a whole.
2ed941
    If identifiable sections of that work are not derived from the
2ed941
    Program, and can be reasonably considered independent and separate
2ed941
    works in themselves, then this License, and its terms, do not
2ed941
    apply to those sections when you distribute them as separate
2ed941
    works.  But when you distribute the same sections as part of a
2ed941
    whole which is a work based on the Program, the distribution of
2ed941
    the whole must be on the terms of this License, whose permissions
2ed941
    for other licensees extend to the entire whole, and thus to each
2ed941
    and every part regardless of who wrote it.</para>
2ed941
    
2ed941
    <para>Thus, it is not the intent of this section to claim rights
2ed941
    or contest your rights to work written entirely by you; rather,
2ed941
    the intent is to exercise the right to control the distribution of
2ed941
    derivative or collective works based on the Program.</para>
2ed941
    
2ed941
    <para>In addition, mere aggregation of another work not based on
2ed941
    the Program with the Program (or with a work based on the Program)
2ed941
    on a volume of a storage or distribution medium does not bring the
2ed941
    other work under the scope of this License.</para>
