+ GNU AFFERO GENERAL PUBLIC LICENSE
+
+ Version 3, 19 November 2007
+
+ Copyright © 2007 Free Software Foundation,
+ Inc. 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

+ 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.
+
+#+BEGIN_EXAMPLE
+ Copyright (C)
+
+ 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 .
+
+#+END_EXAMPLE
+
+ 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 .
