GNU GENERAL PUBLIC LICENSE
|
|
|
|
Version 3, 29 June 2007
|
|
|
|
Copyright © 2007 Free Software Foundation, Inc. <https://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

|
|
|
You should have received a copy of the GNU General Public License along with
|
|
this program. If not, see <https://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 <https://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 <https://www.gnu.org/
|
|
licenses /why-not-lgpl.html>.
