it, thus forming a work based on the Program, and copy and distribute
such modifications or work under the terms of Section 1 above, provi-
ded that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating
that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole
or in part contains or is derived from the Program or any part thereof, to
be licensed as a whole at no charge to all third parties under the terms
of this License.
c) If the modified program normally reads commands interactively when
run, you must cause it, when started running for such interactive use in
the most ordinary way, to print or display an announcement including
an appropriate copyright notice and a notice that there is no warran-
ty (or else, saying that you provide a warranty) and that users may redis-
tribute the program under these conditions, and telling the user how to
view a copy of this License. (Exception: if the Program itself is interactive
but does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifia-
ble sections of that work are not derived from the Program, and can be
reasonably considered independent and separate works in themselves,
then this License, and its terms, do not apply to those sections when you
distribute them as separate works. But when you distribute the same
sections as part of a whole which is a work based on the Program, the
distribution of the whole must be on the terms of this License, whose
permissions for other licensees extend to the entire whole, and thus to
each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your
rights to work written entirely by you; rather, the intent is to exercise the
right to control the distribution of derivative or collective works based
on the Program.
In addition, mere aggregation of another work not based on the Pro-
gram with the Program (or with a work based on the Program) on a vo-
lume of a storage or distribution medium does not bring the other work
under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, un-
der Section 2) in object code or executable form under the terms of Sec-
