+ * GNU AFFERO GENERAL PUBLIC LICENSE
+ * Version 3, 19 November 2007
+ *
+ * Copyright (C) 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.
+ *
+ * beginDate) 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.
+ *
+ * beginDate) 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
+ *
+ * beginDate) 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.
+ *
+ *
+ * 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 .
+ *
+ * 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
+ * .
