+    GNU AFFERO GENERAL PUBLIC LICENSE
+       Version 3, 19 November 2007
+
+Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/> Everyone is
+permitted to copy and distribute verbatim copies of this license document, but
+changing it is not allowed.
+
+    Preamble
+
+The GNU 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 <https://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
+<https://www.gnu.org/licenses/>.
