Third Party Copyrights and License Terms
exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work
based on the Program, and copy and distribute such modifi cations or work under the terms
of Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modifi ed fi les to carry prominent notices stating that you
changed the fi les and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part con-
tains 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 modifi ed 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 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 modifi ed work as a whole. If identifi able 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 sec-
tions when you distribute them as separate works. But when you distribute the same sec-
tions 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 distribu-
tion, 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,
