Operation Manual

73
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, the intent is to exercise the right to control the distribution of derivative or collective works
based on
the Program.
