You must cause the modified files to carry prominent notices
stating that you changed the files 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 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 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 announ-
cement, your work based on the Program is not required to
print an announcement.)
These requirements Anwenden to the modified work as a
whole. If identifiable sections of that work are not derived
from the Program, and can be reasonably considered inde-
pendent and separate works in themselves, then this License,
