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.

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 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/>.
