# GNU GENERAL PUBLIC LICENSE
|

|
|
||||||

Version 3, 29 June 2007
|
||||||
|
|
||||||
|
Copyright © 2007 Free Software Foundation, Inc.
|
||||||
|
<[http://fsf.org/](http://fsf.org/)>
|
||||||
|
|
||||||
|
Everyone is permitted to copy and distribute verbatim copies of this license
|
||||||
|
document, but changing it is not allowed.
|
||||||
|
|
||||||
|
## Preamble
|
||||||
|
|
||||||
|
The GNU General Public License is a free, copyleft license for software and
|
||||||
|
other kinds of works.
|
||||||
|
|
||||||
|
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 GNU 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 GNU 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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
Developers that use the GNU GPL 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.
|
||||||
|
|
||||||
|
For the developers' and authors' protection, the GPL clearly explains that
|
||||||
|
there is no warranty for this free software. For both users' and authors' sake,
|
||||||
|
the GPL requires that modified versions be marked as changed, so that their
|
||||||
|
problems will not be attributed erroneously to authors of previous versions.
|
||||||
|
|
||||||
|
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 GPL 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 GPL, as needed to protect the freedom of users.
|
||||||
|
|
||||||
|
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 GPL assures that patents cannot be used to
|
||||||
|
render the program non-free.
|
||||||
|
|
||||||
|
The precise terms and conditions for copying, distribution and modification
|
||||||
|
follow.
|
||||||
|
|
||||||
|
## TERMS AND CONDITIONS
|
||||||
|
|
||||||
|
### 0. Definitions.
|
||||||
|
|
||||||
|
“This License” refers to version 3 of the GNU General Public License.
|
||||||
|
|
||||||
|
“Copyright” also means copyright-like laws that apply to other kinds of works,
|
||||||
|
such as semiconductor masks.
|
||||||
|
|
||||||
|
“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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
A “covered work” means either the unmodified Program or a work based on the
|
||||||
|
Program.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
### 1. Source Code.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
The Corresponding Source need not include anything that users can regenerate
|
||||||
|
automatically from other parts of the Corresponding Source.
|
||||||
|
|
||||||
|
The Corresponding Source for a work in source code form is that same work.
|
||||||
|
|
||||||
|
### 2. Basic Permissions.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
Conveying under any other circumstances is permitted solely under the
|
||||||
|
conditions stated below. Sublicensing is not allowed; section 10 makes it
|
||||||
|
unnecessary.
|
||||||
|
|
||||||
|
### 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
### 4. Conveying Verbatim Copies.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
### 5. Conveying Modified Source Versions.
|
||||||
|
|
||||||
|
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:
|
||||||
|
|
||||||
|
* a) The work must carry prominent notices stating that you modified it, and
|
||||||
|
giving a relevant date.
|
||||||
|
* 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.
|
||||||
|
|
||||||
|
If the Program specifies that a proxy can decide which future versions of the
|
||||||
|
GNU 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.
|
||||||
|
|
||||||
|
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.
|
||||||
|
|
||||||
|
### 15. Disclaimer of Warranty.
|
||||||
|
|
||||||
|
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE
|
||||||
|
LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER
|
||||||
|
PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER
|
||||||
|
EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
|
||||||
|
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE
|
||||||
|
QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE
|
||||||
|
DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR
|
||||||
|
CORRECTION.
|
||||||
|
|
||||||
|
### 16. Limitation of Liability.
|
||||||
|
|
||||||
|
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY
|
||||||
|
COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS
|
||||||
|
PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
|
||||||
|
INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE
|
||||||
|
THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
|
||||||
|
INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE
|
||||||
|
PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY
|
||||||
|
HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
|
||||||
|
|
||||||
|
### 17. Interpretation of Sections 15 and 16.
|
||||||
|
|
||||||
|
If the disclaimer of warranty and limitation of liability provided above cannot
|
||||||
|
be given local legal effect according to their terms, reviewing courts shall
|
||||||
|
apply local law that most closely approximates an absolute waiver of all civil
|
||||||
|
liability in connection with the Program, unless a warranty or assumption of
|
||||||
|
liability accompanies a copy of the Program in return for a fee.
