You may modify your copy or copies of the Program or any portion of it, 2)
thus forming a work based on the Program, and copy and distribute such
modications or work under the terms of Section 1 above, provided that you
also meet all of these conditions.
You must cause the modied les to carry prominent notices stating that you •
changed the les and the date of any change.
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.
If the modied 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 modied work as a whole.
If identiable 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
