<a class="ulink" href="http://www.fsf.org/" target="_top">http://www.fsf.org/</a>
|
||
</p><p>
|
||
Everyone is permitted to copy and distribute verbatim copies of this license
|
||
document, but changing it is not allowed.
|
||
</p><h2><a id="gpl-3-preamble"></a>
|
||
Preamble
|
||
</h2><p>
|
||
The <acronym class="acronym">GNU</acronym> General Public License is a free, copyleft
|
||
license for software and other kinds of works.
|
||
</p><p>
|
||
The licenses for most software and other practical works are designed to
|
||
take away your freedom to share and change the works. By contrast, the
|
||
<acronym class="acronym">GNU</acronym> General Public License is intended to guarantee your
|
||
freedom to share and change all versions of a program—to make sure it
|
||
remains free software for all its users. We, the Free Software Foundation,
|
||
use the <acronym class="acronym">GNU</acronym> General Public License for most of our
|
||
software; it applies also to any other work released this way by its
|
||
authors. You can apply it to your programs, too.
|
||
</p><p>
|
||
When we speak of free software, we are referring to freedom, not price. Our
|
||
General Public Licenses are designed to make sure that you have the freedom
|
||
to distribute copies of free software (and charge for them if you wish),
|
||
that you receive source code or can get it if you want it, that you can
|
||
change the software or use pieces of it in new free programs, and that you
|
||
know you can do these things.
|
||
</p><p>
|
||
To protect your rights, we need to prevent others from denying you these
|
||
rights or asking you to surrender the rights. Therefore, you have certain
|
||
responsibilities if you distribute copies of the software, or if you modify
|
||
it: responsibilities to respect the freedom of others.
|
||
</p><p>
|
||
For example, if you distribute copies of such a program, whether gratis or
|
||
for a fee, you must pass on to the recipients the same freedoms that you
|
||
received. You must make sure that they, too, receive or can get the source
|
||
code. And you must show them these terms so they know their rights.
|
||
</p><p>
|
||
Developers that use the <acronym class="acronym">GNU</acronym> <acronym class="acronym">GPL</acronym>
|
||
protect your rights with two steps: (1) assert copyright on the software,
|
||
and (2) offer you this License giving you legal permission to copy,
|
||
distribute and/or modify it.
|
||
</p><p>
|
||
For the developers’ and authors’ protection, the
|
||
<acronym class="acronym">GPL</acronym> clearly explains that there is no warranty for this
|
||
free software. For both users’ and authors’ sake, the
|
||
<acronym class="acronym">GPL</acronym> requires that modified versions be marked as changed,
|
||
so that their problems will not be attributed erroneously to authors of
|
||
previous versions.
|
||
</p><p>
|
||
Some devices are designed to deny users access to install or run modified
|
||
versions of the software inside them, although the manufacturer can do so.
|
||
This is fundamentally incompatible with the aim of protecting users’
|
||
freedom to change the software. The systematic pattern of such abuse occurs
|
||
in the area of products for individuals to use, which is precisely where it
|
||
is most unacceptable. Therefore, we have designed this version of the
|
||
<acronym class="acronym">GPL</acronym> to prohibit the practice for those products. If such
|
||
problems arise substantially in other domains, we stand ready to extend this
|
||
provision to those domains in future versions of the <acronym class="acronym">GPL</acronym>,
|
||
as needed to protect the freedom of users.
|
||
</p><p>
|
||
Finally, every program is threatened constantly by software patents. States
|
||
should not allow patents to restrict development and use of software on
|
||
general-purpose computers, but in those that do, we wish to avoid the
|
||
special danger that patents applied to a free program could make it
|
||
effectively proprietary. To prevent this, the <acronym class="acronym">GPL</acronym>
|
||
assures that patents cannot be used to render the program non-free.
|
||
</p><p>
|
||
The precise terms and conditions for copying, distribution and modification
|
||
follow.
|
||
</p><h2><a id="id487484"></a>
|
||
TERMS AND CONDITIONS
|
||
</h2><h2><a id="gpl-3-definitions"></a>
|
||
0. Definitions.
|
||
</h2><p>
|
||
“This License” refers to version 3 of the <acronym class="acronym">GNU</acronym>
|
||
General Public License.
|
||
</p><p>
|
||
“Copyright” also means copyright-like laws that apply to other
|
||
kinds of works, such as semiconductor masks.
|
||
</p><p>
|
||
“The Program” refers to any copyrightable work licensed under
|
||
this License. Each licensee is addressed as “you”.
|
||
“Licensees” and “recipients” may be individuals or
|
||
organizations.
|
||
</p><p>
|
||
To “modify” a work means to copy from or adapt all or part of
|
||
the work in a fashion requiring copyright permission, other than the making
|
||
of an exact copy. The resulting work is called a “modified
|
||
version” of the earlier work or a work “based on” the
|
||
earlier work.
|
||
</p><p>
|
||
A “covered work” means either the unmodified Program or a work
|
||
based on the Program.
|
||
</p><p>
|
||
To “propagate” a work means to do anything with it that, without
|
||
permission, would make you directly or secondarily liable for infringement
|
||
under applicable copyright law, except executing it on a computer or
|
||
modifying a private copy. Propagation includes copying, distribution (with
|
||
or without modification), making available to the public, and in some
|
||
countries other activities as well.
|
||
</p><p>
|
||
To “convey” a work means any kind of propagation that enables
|
||
other parties to make or receive copies. Mere interaction with a user
|
||
through a computer network, with no transfer of a copy, is not conveying.
|
||
</p><p>
|
||
An interactive user interface displays “Appropriate Legal
|
||
Notices” to the extent that it includes a convenient and prominently
|
||
visible feature that (1) displays an appropriate copyright notice, and (2)
|
||
tells the user that there is no warranty for the work (except to the extent
|
||
that warranties are provided), that licensees may convey the work under this
|
||
License, and how to view a copy of this License. If the interface presents
|
||
a list of user commands or options, such as a menu, a prominent item in the
|
||
list meets this criterion.
|
||
</p><h2><a id="SourceCode"></a>
|
||
1. Source Code.
|
||
</h2><p>
|
||
The “source code” for a work means the preferred form of the
|
||
work for making modifications to it. “Object code” means any
|
||
non-source form of a work.
|
||
</p><p>
|
||
A “Standard Interface” means an interface that either is an
|
||
official standard defined by a recognized standards body, or, in the case of
|
||
interfaces specified for a particular programming language, one that is
|
||
widely used among developers working in that language.
|
||
</p><p>
|
||
The “System Libraries” of an executable work include anything,
|
||
other than the work as a whole, that (a) is included in the normal form of
|
||
packaging a Major Component, but which is not part of that Major Component,
|
||
and (b) serves only to enable use of the work with that Major Component, or
|
||
to implement a Standard Interface for which an implementation is available
|
||
to the public in source code form. A “Major Component”, in this
|
||
context, means a major essential component (kernel, window system, and so
|
||
on) of the specific operating system (if any) on which the executable work
|
||
runs, or a compiler used to produce the work, or an object code interpreter
|
||
used to run it.
|
||
</p><p>
|
||
The “Corresponding Source” for a work in object code form means
|
||
all the source code needed to generate, install, and (for an executable
|
||
work) run the object code and to modify the work, including scripts to
|
||
control those activities. However, it does not include the work’s
|
||
System Libraries, or general-purpose tools or generally available free
|
||
programs which are used unmodified in performing those activities but which
|
||
are not part of the work. For example, Corresponding Source includes
|
||
interface definition files associated with source files for the work, and
|
||
the source code for shared libraries and dynamically linked subprograms that
|
||
the work is specifically designed to require, such as by intimate data
|
||
communication or control flow between those subprograms and other parts of
|
||
the work.
|
||
</p><p>
|
||
The Corresponding Source need not include anything that users can regenerate
|
||
automatically from other parts of the Corresponding Source.
|
||
</p><p>
|
||
The Corresponding Source for a work in source code form is that same work.
|
||
</p><h2><a id="BasicPermissions"></a>
|
||
2. Basic Permissions.
|
||
</h2><p>
|
||
All rights granted under this License are granted for the term of copyright
|
||
on the Program, and are irrevocable provided the stated conditions are met.
|
||
This License explicitly affirms your unlimited permission to run the
|
||
unmodified Program. The output from running a covered work is covered by
|
||
this License only if the output, given its content, constitutes a covered
|
||
work. This License acknowledges your rights of fair use or other
|
||
equivalent, as provided by copyright law.
|
||
</p><p>
|
||
You may make, run and propagate covered works that you do not convey,
|
||
without conditions so long as your license otherwise remains in force. You
|
||
may convey covered works to others for the sole purpose of having them make
|
||
modifications exclusively for you, or provide you with facilities for
|
||
running those works, provided that you comply with the terms of this License
|
||
in conveying all material for which you do not control copyright. Those
|
||
thus making or running the covered works for you must do so exclusively on
|
||
your behalf, under your direction and control, on terms that prohibit them
|
||
from making any copies of your copyrighted material outside their
|
||
relationship with you.
|
||
</p><p>
|
||
Conveying under any other circumstances is permitted solely under the
|
||
conditions stated below. Sublicensing is not allowed; section 10 makes it
|
||
unnecessary.
|
||
</p><h2><a id="Protecting"></a>
|
||
3. Protecting Users’ Legal Rights From Anti-Circumvention Law.
|
||
</h2><p>
|
||
No covered work shall be deemed part of an effective technological measure
|
||
under any applicable law fulfilling obligations under article 11 of the WIPO
|
||
copyright treaty adopted on 20 December 1996, or similar laws prohibiting or
|
||
restricting circumvention of such measures.
|
||
</p><p>
|
||
When you convey a covered work, you waive any legal power to forbid
|
||
circumvention of technological measures to the extent such circumvention is
|
||
effected by exercising rights under this License with respect to the covered
|
||
work, and you disclaim any intention to limit operation or modification of
|
||
the work as a means of enforcing, against the work’s users, your or
|
||
third parties’ legal rights to forbid circumvention of technological
|
||
measures.
|
||
</p><h2><a id="ConveyingVerbatim"></a>
|
||
4. Conveying Verbatim Copies.
|
||
</h2><p>
|
||
You may convey verbatim copies of the Program’s source code as you
|
||
receive it, in any medium, provided that you conspicuously and appropriately
|
||
publish on each copy an appropriate copyright notice; keep intact all
|
||
notices stating that this License and any non-permissive terms added in
|
||
accord with section 7 apply to the code; keep intact all notices of the
|
||
absence of any warranty; and give all recipients a copy of this License
|
||
along with the Program.
|
||
</p><p>
|
||
You may charge any price or no price for each copy that you convey, and you
|
||
may offer support or warranty protection for a fee.
|
||
</p><h2><a id="ConveyingModified"></a>
|
||
5. Conveying Modified Source Versions.
|
||
</h2><p>
|
||
You may convey a work based on the Program, or the modifications to produce
|
||
it from the Program, in the form of source code under the terms of section
|
||
4, provided that you also meet all of these conditions:
|
||
</p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p>
|
||
The work must carry prominent notices stating that you modified it, and
|
||
giving a relevant date.
|
||
</p></li><li class="listitem"><p>
|
||
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”.
|
||
</p></li><li class="listitem"><p>
|
||
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.
|
||
</p></li><li class="listitem"><p>
|
||
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.
|
||
</p></li></ol></div><p>
|
||
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.
|
||
</p><h2><a id="ConveyingNonSource"></a>
|
||
6. Conveying Non-Source Forms.
|
||
</h2><p>
|
||
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:
|
||
</p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p>
|
||
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.
|
||
</p></li><li class="listitem"><p>
|
||
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.
|
||
</p></li><li class="listitem"><p>
|
||
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.
|
||
</p></li><li class="listitem"><p>
|
||
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.
|
||
</p></li><li class="listitem"><p>
|
||
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.
|
||
</p></li></ol></div><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
“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.
|
||
</p><p>
|
||
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
|
||
<acronym class="acronym">ROM</acronym>).
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><h2><a id="AdditionalTerms"></a>
|
||
7. Additional Terms.
|
||
</h2><p>
|
||
“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.
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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:
|
||
</p><div class="orderedlist"><ol class="orderedlist" type="a"><li class="listitem"><p>

liability that these contractual assumptions directly impose on those
|
||
licensors and authors.
|
||
</p></li></ol></div><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><h2><a id="gpl-3-termination"></a>
|
||
8. Termination.
|
||
</h2><p>
|
||
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).
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><h2><a id="AcceptanceNotRequired"></a>
|
||
9. Acceptance Not Required for Having Copies.
|
||
</h2><p>
|
||
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.
|
||
</p><h2><a id="AutomaticDownstream"></a>
|
||
10. Automatic Licensing of Downstream Recipients.
|
||
</h2><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><h2><a id="Patents"></a>
|
||
11. Patents.
|
||
</h2><p>
|
||
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”.
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><p>
|
||
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.
|
||
</p><h2><a id="NoSurrender"></a>
|
||
12. No Surrender of Others’ Freedom.
|
||
</h2><p>
|
||
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 <acronym class="acronym">GNU</acronym> Affero General Public License.
|
||
</h2><p>
|
||
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
|
||
<acronym class="acronym">GNU</acronym> 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 <acronym class="acronym">GNU</acronym> Affero General Public License,
|

section 13, concerning interaction through a network will apply to the
|
||
combination as such.

</p><h2><a id="RevisedVersions"></a>

14. Revised Versions of this License.
|

</h2><p>
|

The Free Software Foundation may publish revised and/or new versions of the

<acronym class="acronym">GNU</acronym> 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.
|
||
</p><p>
|
||
Each version is given a distinguishing version number. If the Program
|
||
specifies that a certain numbered version of the <acronym class="acronym">GNU</acronym>
|
||
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
|
||
<acronym class="acronym">GNU</acronym> General Public License, you may choose any version
|
||
ever published by the Free Software Foundation.
|
||
</p><p>
|
||
If the Program specifies that a proxy can decide which future versions of
|
||
the <acronym class="acronym">GNU</acronym> General Public License can be used, that
|
||
proxy’s public statement of acceptance of a version permanently
|
||
authorizes you to choose that version for the Program.
|

</p><p>
|

Later license versions may give you additional or different permissions.
|

However, no additional obligations are imposed on any author or copyright

holder as a result of your choosing to follow a later version.

|

How to Apply These Terms to Your New Programs
|
||
</h2><p>
|
||
If you develop a new program, and you want it to be of the greatest possible
|
||
use to the public, the best way to achieve this is to make it free software
|
||
which everyone can redistribute and change under these terms.
|
||
</p><p>
|
||
To do so, attach the following notices to the program. It is safest to
|
||
attach them to the start of each source file to most effectively state the
|
||
exclusion of warranty; and each file should have at least the
|
||
“copyright” line and a pointer to where the full notice is
|
||
found.
|
||
</p><pre class="screen">

||

|
||
|
||
This program is free software: you can redistribute it and/or modify
|
||
it under the terms of the <acronym class="acronym">GNU</acronym> General Public License as published by

the Free Software Foundation, either version 3 of the License, or
|
||
(at your option) any later version.

|

This program is distributed in the hope that it will be useful,
|
||
but WITHOUT ANY WARRANTY; without even the implied warranty of
|
||
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
|
||
<acronym class="acronym">GNU</acronym> General Public License for more details.
|
||
|
||
You should have received a copy of the <acronym class="acronym">GNU</acronym> General Public License
|
||
along with this program. If not, see <a class="ulink" href="http://www.gnu.org/licenses/" target="_top">http://www.gnu.org/licenses/</a>.
|
||
</pre><p>
|
||
Also add information on how to contact you by electronic and paper mail.
|
||
</p><p>
|
||
If the program does terminal interaction, make it output a short notice like
|
||
this when it starts in an interactive mode:
|
||
</p><pre class="screen">

This program comes with ABSOLUTELY NO WARRANTY; for details type ‘<code class="literal">show w</code>’.
|
||
This is free software, and you are welcome to redistribute it
|
||
under certain conditions; type ‘<code class="literal">show c</code>’ for details.
|
||
</pre><p>
|
||
The hypothetical commands ‘<code class="literal">show w</code>’ and
|
||
‘<code class="literal">show c</code>’ should show the appropriate parts of
|
||
the General Public License. Of course, your program’s commands might be
|
||
different; for a GUI interface, you would use an “about box”.
|
||
</p><p>
|
||
You should also get your employer (if you work as a programmer) or school,
|
||
if any, to sign a “copyright disclaimer” for the program, if
|
||
necessary. For more information on this, and how to apply and follow the

The <acronym class="acronym">GNU</acronym> General Public License does not permit

incorporating your program into proprietary programs. If your program is a
