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 no-
tices 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 Pro-
gram 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 inter-
actively 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 copy-
right notice and a notice that there is no warranty (or else,
saying that you provide a warranty) and that users may re-
distribute 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
