gnu general public license
|
|
version 3, 29 june 2007
|
|
|
|
copyright (c) 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 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 <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>.
