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 modifications 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 charge 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,
