GNU GENERAL PUBLIC LICENSE
|
||
|
|
==========================
|
||
|
|
|
||
|
|
Version 3, 29 June 2007
|
||
|
|
|
||
|
|
Copyright © 2007 Free Software Foundation, Inc. <<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.
|
||
|
|
|
||
|
|
END OF TERMS AND CONDITIONS
|
||
|
|
|
||
|
|
## How to Apply These Terms to Your New Programs
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
<one line to give the program's name and a brief idea of what it does.>
|
||
|
|
Copyright (C) <year> <name of author>
|
||
|
|
|
||
|
|
This program is free software: you can redistribute it and/or modify
|
||
|
|
it under the terms of the GNU 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
|
||
|
|
GNU General Public License for more details.
|
||
|
|
|
||
|
|
You should have received a copy of the GNU General Public License
|
||
|
|
along with this program. If not, see <http://www.gnu.org/licenses/>.
|
||
|
|
|
||
|
|
Also add information on how to contact you by electronic and paper mail.
|
||
|
|
|
||
|
|
If the program does terminal interaction, make it output a short notice like this
|
||
|
|
when it starts in an interactive mode:
|
||
|
|
|
||
|
|
<program> Copyright (C) <year> <name of author>
|
||
|
|
This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'.
|
||
|
|
This is free software, and you are welcome to redistribute it
|
||
|
|
under certain conditions; type 'show c' for details.
|
||
|
|
|
||
|
|
The hypothetical commands 'show w' and 'show c' 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”.
|
||
|
|
|
||
|
|
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 GNU GPL, see
|
||
|
|
<<http://www.gnu.org/licenses/>>.
|
||
|
|
|
||
|
|
The GNU General Public License does not permit incorporating your program into
|
||
|
|
proprietary programs. If your program is a subroutine library, you may consider it
|
||
|
|
more useful to permit linking proprietary applications with the library. If this is
|
||
|
|
what you want to do, use the GNU Lesser General Public License instead of this
|
||
|
|
License. But first, please read
|
||
|
|
<<http://www.gnu.org/philosophy/why-not-lgpl.html>>.
