b) The work must carry prominent notices stating that it is released
under this License and any conditions added under section 7. This
requirement modifies the requirement in section 4 to "keep intact all
notices".
c) You must license the entire work, as a whole, under this License to
anyone who comes into possession of a copy. This License will
therefore apply, along with any applicable section 7 additional terms,
to the whole of the work, and all its parts, regardless of how they are
packaged. This License gives no permission to license the work in
any other way, but it does not invalidate such permission if you have
separately received it.
d) If the work has interactive user interfaces, each must display
Appropriate Legal Notices; however, if the Program has interactive
interfaces that do not display Appropriate Legal Notices, your work
need not make them do so.
A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work, and
which are not combined with it such as to form a larger program, in or on
a volume of a storage or distribution medium, is called an "aggregate" if
the compilation and its resulting copyright are not used to limit the
access or legal rights of the compilation's users beyond what the
individual works permit. Inclusion of a covered work in an aggregate
does not cause this License to apply to the other parts of the aggregate.
6. Conveying non-source forms.
You may convey a covered work in object code form under the terms of
sections 4 and 5, provided that you also convey the machine-readable
Corresponding Source under the terms of this License, in one of these
ways:
a) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by the
Corresponding Source fixed on a durable physical medium
customarily used for software interchange.
b) Convey the object code in, or embodied in, a physical product
(including a physical distribution medium), accompanied by a written
offer, valid for at least three years and valid for as long as you offer
spare parts or customer support for that product model, to give
anyone who possesses the object code either (1) a copy of the
Corresponding Source for all the software in the product that is
covered by this License, on a durable physical medium customarily
used for software interchange, for a price no more than your
reasonable cost of physically performing this conveying of source, or
(2) access to copy the Corresponding Source from a network server
at no charge.
c) Convey individual copies of the object code with a copy of the
written offer to provide the Corresponding Source. This alternative is
allowed only occasionally and noncommercially, and only if you
received the object code with such an offer, in accord with subsection
6b.
d) Convey the object code by offering access from a designated place
(gratis or for a charge), and offer equivalent access to the
Corresponding Source in the same way through the same place at no
further charge. You need not require recipients to copy the
Corresponding Source along with the object code. If the place to
copy the object code is a network server, the Corresponding Source
may be on a different server (operated by you or a third party) that
supports equivalent copying facilities, provided you maintain clear
directions next to the object code saying where to find the
Corresponding Source. Regardless of what server hosts the
Corresponding Source, you remain obligated to ensure that it is
available for as long as needed to satisfy these requirements.
e) Convey the object code using peer-to-peer transmission, provided
you inform other peers where the object code and Corresponding
Source of the work are being offered to the general public at no
charge under subsection 6d.
A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family, or
household purposes, or (2) anything designed or sold for incorporation
into a dwelling. In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage. For a particular
product received by a particular user, "normally used" refers to a typical
or common use of that class of product, regardless of the status of the
particular user or of the way in which the particular user actually uses, or
expects or is expected to use, the product. A product is a consumer
product regardless of whether the product has substantial commercial,
industrial or non-consumer uses, unless such uses represent the only
significant mode of use of the product.
"Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product
from a modified version of its Corresponding Source. The information
must suffice to ensure that the continued functioning of the modified
object code is in no case prevented or interfered with solely because
modification has been made.
If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as part
of a transaction in which the right of possession and use of the User
Product is transferred to the recipient in perpetuity or for a fixed term
(regardless of how the transaction is characterized), the Corresponding
Source conveyed under this section must be accompanied by the
Installation Information. But this requirement does not apply if neither you
nor any third party retains the ability to install modified object code on the
User Product (for example, the work has been installed in ROM).
The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for the
User Product in which it has been modified or installed. Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
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 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 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.
12. no surrender of others' freedom.
If conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not convey it at all. For example, if you agree to terms that obligate
you to collect a royalty for further conveying from those to whom you
convey the Program, the only way you could satisfy both those terms
and this License would be to refrain entirely from conveying the Program.
13. use with the gnu affero general public license.
Notwithstanding any other provision of this License, you have permission
to link or combine any covered work with a work licensed under version
3 of the GNU Affero General Public License into a single combined work,
and to convey the resulting work. The terms of this License will continue
to apply to the part which is the covered work, but the special
requirements of the GNU Affero General Public License, section 13,
concerning interaction through a network will apply to the combination
as such.
14. revised versions of this license.
The Free Software Foundation may publish revised and/or new versions
of the GNU General Public License from time to time. Such new versions
will be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies that a certain numbered version of the GNU General Public
License "or any later version" applies to it, you have the option of
following the terms and conditions either of that numbered version or of
any later version published by the Free Software Foundation. If the
Program does not specify a version number of the GNU General Public
License, you may choose any version ever published by the Free
Software Foundation.
