## GNU AFFERO GENERAL PUBLIC LICENSE
|
|
|
|
Version 3, 19 November 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 Affero General Public License is a free, copyleft license for
|
|
software and other kinds of works, specifically designed to ensure
|
|
cooperation with the community in the case of network server software.
|
|
|
|
The licenses for most software and other practical works are designed to
|
|
take away your freedom to share and change the works. By contrast, our
|
|
General Public Licenses are 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.
|
|
|
|
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.
|
|
|
|
Developers that use our General Public Licenses protect your rights with
|
|
two steps: (1) assert copyright on the software, and (2) offer you this
|
|
License which gives you legal permission to copy, distribute and/or
|
|
modify the software.
|
|
|
|
A secondary benefit of defending all users' freedom is that improvements
|
|
made in alternate versions of the program, if they receive widespread
|
|
use, become available for other developers to incorporate. Many
|
|
developers of free software are heartened and encouraged by the
|
|
resulting cooperation. However, in the case of software used on network
|
|
servers, this result may fail to come about. The GNU General Public
|
|
License permits making a modified version and letting the public access
|
|
it on a server without ever releasing its source code to the public.
|
|
|
|
The GNU Affero General Public License is designed specifically to ensure
|
|
that, in such cases, the modified source code becomes available to the
|
|
community. It requires the operator of a network server to provide the
|
|
source code of the modified version running there to the users of that
|
|
server. Therefore, public use of a modified version, on a publicly
|
|
accessible server, gives the public access to the source code of the
|
|
modified version.
|
|
|
|
An older license, called the Affero General Public License and published
|
|
by Affero, was designed to accomplish similar goals. This is a different
|
|
license, not a version of the Affero GPL, but Affero has released a new
|
|
version of the Affero GPL which permits relicensing under this license.
|
|
|
|
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 Affero 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. Remote Network Interaction; Use with the GNU General Public License.
|
|
|
|
Notwithstanding any other provision of this License, if you modify the
|
|
Program, your modified version must prominently offer all users
|
|
interacting with it remotely through a computer network (if your version
|
|
supports such interaction) an opportunity to receive the Corresponding
|
|
Source of your version by providing access to the Corresponding Source
|
|
from a network server at no charge, through some standard or customary
|
|
means of facilitating copying of software. This Corresponding Source
|
|
shall include the Corresponding Source for any work covered by version 3
|
|
of the GNU General Public License that is incorporated pursuant to the
|
|
following paragraph.
|
|
|
|
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 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 work with which it
|
|
is combined will remain governed by version 3 of the GNU General Public
|
|
License.
|
|
|
|
#### 14. Revised Versions of this License.
|
|
|
|
The Free Software Foundation may publish revised and/or new versions of
|
|
the GNU Affero 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 Affero 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 Affero 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 Affero 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.
|
|
|

### 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 Affero 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 Affero General Public License for more details.
|
|
|
|
You should have received a copy of the GNU Affero 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 your software can interact with users remotely through a computer
|
|
network, you should also make sure that it provides a way for users to
|
|
get its source. For example, if your program is a web application, its
|
|
interface could display a "Source" link that leads users to an archive
|
|
of the code. There are many ways you could offer source, and different
|
|
solutions will be better for different programs; see section 13 for the
|
|
specific requirements.
|
|
|
|
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 AGPL, see \<<http://www.gnu.org/licenses/>\>.
