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 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.
If you convey a covered work, knowingly relying on a patent license, and
the Corresponding Source of the work is not available for anyone to copy,
free of charge and under the terms of this License, through a publicly
available network server or other readily accessible means, then you must
either ( 1 ) cause the Corresponding Source to be so available, or ( 2 ) arrange
to deprive yourself of the benefit of the patent license for this particular
work, or ( 3 ) arrange, in a manner consistent with the requirements of this
License, to extend the patent license to downstream recipients. "Knowingly
relying" means you have actual knowledge that, but for the patent license,
your conveying the covered work in a country, or your recipient's use of the
covered work in a country, would infringe one or more identifiable patents in
that country that you have reason to believe are valid.
If, pursuant to or in connection with a single transaction or arrangement,
you convey, or propagate by procuring conveyance of, a covered work,
and grant a patent license to some of the parties receiving the covered
work authorizing them to use, propagate, modify or convey a specific
copy of the covered work, then the patent license you grant is
automatically extended to all recipients of the covered work and works
based on it.
A patent license is "discriminatory" if it does not include within the scope
of its coverage, prohibits the exercise of, or is conditioned on the
non-exercise of one or more of the rights that are specifically granted
under this License. You may not convey a covered work if you are a party
to an arrangement with a third party that is in the business of distributing
software, under which you make payment to the third party based on the
extent of your activity of conveying the work, and under which the third
party grants, to any of the parties who would receive the covered work
from you, a discriminatory patent license ( a ) in connection with copies of
the covered work conveyed by you ( or copies made from those copies ) ,
or ( b ) primarily for and in connection with specific products or
compilations that contain the covered work, unless you entered into that
arrangement, or that patent license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any
implied license or other defenses to infringement that may otherwise be
available to you under applicable patent law.
