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

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
tellingtheuserhowtoviewacopyofthisLicense.(Exception:iftheProgramitselfisinteractivebut

These requirements apply to the modified work as a whole. If identifiable sections of that work are

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 collective
