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 physically performing source
distribution, a complete machine-readable copy of the
corresponding source code, to
