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 warranty (or else, saying that you provide a
warranty) and that users may redistribute 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
identifiable 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
Program with the Program (or with a work based on the Program)
on a volume 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, 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:
a) 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,
b) 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
