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>

    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/>.
