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.
An “entity transaction” is a transaction transferring
control of an organization, or substantially all assets of
one, or subdividing an organization, or merging
organizations. If propagation of a covered work results
from an entity transaction, each party to that transaction
who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest
had or could give under the previous paragraph, plus a
right to possession of the Corresponding Source of the
work from the predecessor in interest, if the
predecessor has it or can get it with reasonable efforts.
You may not impose any further restrictions on the
exercise of the rights granted or affirmed under this
License. For example, you may not impose a license
fee, royalty, or other charge for exercise of rights
granted under this License, and you may not initiate
