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 addi-
tional permissions.
When you convey a copy of a covered work, you
may at your option remove any additional permis-
sions from that copy, or from any part of it. (Addi-
tional 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 permis-
sion.
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 differ-
ently from the terms of sections 15 and 16 of this
License; or
* b) Requiring preservation of specified reasona-
ble legal notices or author attributions in that
material or in the Appropriate Legal Notices dis-
played 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 ser-
vice marks; or
* f) Requiring indemnification of licensors and
authors of that material by anyone who conveys
the material (or modified versions of it) with con-
tractual assumptions of liability to the recipient,
for any liability that these contractual assump-
tions directly impose on those licensors and
authors.
All other non-permissive additional terms are con-
sidered “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 reasona-
ble 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 reasona-
ble 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 accept-
ance. 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 prede-
cessor 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 import-
ing the Program or any portion of it.
11. Pa tent s.
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 pat-
ent 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 contribu-
tor version, but do not include claims that would be
infringed only as a consequence of further modifica-
tion of the contributor version. For purposes of this
definition, “control” includes the right to grant patent
sublicenses in a manner consistent with the require-
ments of this License.
Each contributor grants you a non-exclusive, world-
wide, royalty-free patent license under the contribu-
tor's essential patent claims, to make, use, sell, offer
for sale, import and otherwise run, modify and prop-
agate 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 pat-
ent 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 transac-
tion 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 automati-
cally 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-exer-
cise 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 distribut-
ing 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 arrange-
ment, or that patent license was granted, prior to 28
March 2007.
