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
"furtherrestrictions" 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
yourlicense 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 thelicenses 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 acovered
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 therights 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 litigation (including a
cross-claim or counterclaim in a lawsuit) alleging that any
patent claim is infringed by making, using, selling, offering
for sale, or importing the Program or any portion of it.
11. Patents.
A "contributor" is a copyright holder who authorizes
use under this License of the Program or a work on
which the Program is based. The work thus licensed
is called the contributor's "contributor version".
A contributor's "essential patent claims" are all patent
claims owned or controlled by the contributor, whether
already acquired or hereafter acquired, that would be
infringed by some manner, permitted by this License,
of making, using, or selling its contributor version, but
do not include claims that would be infringed only as a
consequence of further modification of the contributor
version. For purposes of this definition, "control"
includes the right to grant patent sublicenses in a manner
consistent with the requirements of this License.
Each contributor grants you a non-exclusive,
worldwide, royalty-free patent license under the
contributor's essential patent claims, to make, use, sell,
offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
In the following three paragraphs, a "patent license"
is any express agreement or commitment, however
denominated, not to enforce a patent (such as an express
permission to practice a patent or covenant not to sue
for patent infringement). To "grant" such a patent
license to a party means to make such an agreement or
commitment not to enforce a patent against the party.
