or work under the terms of Section 1 above, provided 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 cha rge 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 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 c ollective 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
