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
ofthe 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,
royaltyfree 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.
