occurs as part of a transaction in which the right of possession
and use of the User Product is transferred to the recipient in
perpetuity or for a fixed term (regardless of how the transaction
is characterized), the Corresponding Source conveyed under this
section must be accompanied by the Installation Information. But
this requirement does not apply if neither you nor any third
party retains the ability to install modified object code on the
User Product (for example, the work has been installed in
ROM).
The requirement to provide Installation Information does not
include a requirement to continue to provide support service,
warranty, or updates for a work that has been modified or
installed by the recipient, or for the User Product in which it has
been modified or installed. Access to a network may be denied
when the modification itself materially and adversely affects the
operation of the network or violates the rules and protocols for
communication across the network.
Corresponding Source conveyed, and Installation Information
provided, in accord with this section must be in a format that is
publicly documented (and with an implementation available to
the public in source code form), and must require no special
password or key for unpacking, reading or copying.
7. Additional Terms.
"Additional permissions" are terms that supplement the terms of
this License by making exceptions from one or more of its
conditions. Additional permissions that are applicable to the
entire Program shall be treated as though they were included in
this License, to the extent that they are valid under applicable
law. If additional permissions apply only to part of the Program,
that part may be used separately under those permissions, but
the entire Program remains governed by this License without
regard to the additional permissions.
When you convey a copy of a covered work, you may at your
option remove any additional permissions from that copy, or
from any part of it. (Additional permissions may be written to
require their own removal in certain cases when you modify the
work.) You may place additional permissions on material, added
by you to a covered work, for which you have or can give
appropriate copyright permission.
Notwithstanding any other provision of this License, for material
you add to a covered work, you may (if authorized by the
copyright holders of that material) supplement the terms of this
License with terms:
•a) Disclaiming warranty or limiting liability differently from the
terms of sections 15 and 16 of this License; or •b) Requiring
preservation of specified reasonable legal notices or author
attributions in that material or in the Appropriate Legal Notices
displayed by works containing it; or •c) Prohibiting
misrepresentation of the origin of that material, or requiring that
modified versions of such material be marked in reasonable ways
as different from the original version; or •d) Limiting the use for
publicity purposes of names of licensors or authors of the
material; or •e) Declining to grant rights under trademark law
for use of some trade names, trademarks, or service marks; or
•f) Requiring indemnification of licensors and authors of that
material by anyone who conveys the material (or modified
versions of it) with contractual assumptions of liability to the
recipient, for any liability that these contractual assumptions
directly impose on those licensors and authors.
All other non-permissive additional terms are considered
"further restrictions" within the meaning of section 10. If the
Program as you received it, or any part of it, contains a notice
stating that it is governed by this License along with a term that
is a further restriction, you may remove that term. If a license
document contains a further restriction but permits relicensing
or conveying under this License, you may add to a covered work
material governed by the terms of that license document,
provided that the further restriction does not survive such
relicensing or conveying.
If you add terms to a covered work in accord with this section,
you must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
Additional terms, permissive or non-permissive, may be stated in
the form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
You may not propagate or modify a covered work except as
expressly provided under this License. Any attempt otherwise to
propagate or modify it is void, and will automatically terminate
your rights under this License (including any patent licenses
granted under the third paragraph of section 11).
However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the
copyright holder fails to notify you of the violation by some
reasonable means prior to 60 days after the cessation.
Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you
have received notice of violation of this License (for any work)
from that copyright holder, and you cure the violation prior to
30 days after your receipt of the notice.
Termination of your rights under this section does not terminate
the licenses of parties who have received copies or rights from
you under this License. If your rights have been terminated and
not permanently reinstated, you do not qualify to receive new
licenses for the same material under section 10.
9. Acceptance Not Required for Having Copies.
You are not required to accept this License in order to receive
or run a copy of the Program. Ancillary propagation of a
covered work occurring solely as a consequence of using peer-
to-peer transmission to receive a copy likewise does not require
acceptance. However, nothing other than this License grants you
permission to propagate or modify any covered work. These
actions infringe copyright if you do not accept this License.
Therefore, by modifying or propagating a covered work, you
indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
Each time you convey a covered work, the recipient
automatically receives a license from the original licensors, to
run, modify and propagate that work, subject to this License.
You are not responsible for enforcing compliance by third
parties with this License.
