+ GNU AFFERO GENERAL PUBLIC LICENSE\r
+ Version 3, 19 November 2007\r
+\r
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>\r
+ Everyone is permitted to copy and distribute verbatim copies\r
+ of this license document, but changing it is not allowed.\r
+\r
+ Preamble\r
+\r
+ The GNU Affero General Public License is a free, copyleft license for\r
+software and other kinds of works, specifically designed to ensure\r
+cooperation with the community in the case of network server software.\r
+\r
+ The licenses for most software and other practical works are designed\r
+to take away your freedom to share and change the works. By contrast,\r
+our General Public Licenses are intended to guarantee your freedom to\r
+share and change all versions of a program--to make sure it remains free\r
+software for all its users.\r
+\r
+ When we speak of free software, we are referring to freedom, not\r
+price. Our General Public Licenses are designed to make sure that you\r
+have the freedom to distribute copies of free software (and charge for\r
+them if you wish), that you receive source code or can get it if you\r
+want it, that you can change the software or use pieces of it in new\r
+free programs, and that you know you can do these things.\r
+\r
+ Developers that use our General Public Licenses protect your rights\r
+with two steps: (1) assert copyright on the software, and (2) offer\r
+you this License which gives you legal permission to copy, distribute\r
+and/or modify the software.\r
+\r
+ A secondary benefit of defending all users' freedom is that\r
+improvements made in alternate versions of the program, if they\r
+receive widespread use, become available for other developers to\r
+incorporate. Many developers of free software are heartened and\r
+encouraged by the resulting cooperation. However, in the case of\r
+software used on network servers, this result may fail to come about.\r
+The GNU General Public License permits making a modified version and\r
+letting the public access it on a server without ever releasing its\r
+source code to the public.\r
+\r
+ The GNU Affero General Public License is designed specifically to\r
+ensure that, in such cases, the modified source code becomes available\r
+to the community. It requires the operator of a network server to\r
+provide the source code of the modified version running there to the\r
+users of that server. Therefore, public use of a modified version, on\r
+a publicly accessible server, gives the public access to the source\r
+code of the modified version.\r
+\r
+ An older license, called the Affero General Public License and\r
+published by Affero, was designed to accomplish similar goals. This is\r
+a different license, not a version of the Affero GPL, but Affero has\r
+released a new version of the Affero GPL which permits relicensing under\r
+this license.\r
+\r
+ The precise terms and conditions for copying, distribution and\r
+modification follow.\r
+\r
+ TERMS AND CONDITIONS\r
+\r
+ 0. Definitions.\r
+\r
+ "This License" refers to version 3 of the GNU Affero General Public License.\r
+\r
+ "Copyright" also means copyright-like laws that apply to other kinds of\r
+works, such as semiconductor masks.\r
+\r
+ "The Program" refers to any copyrightable work licensed under this\r
+License. Each licensee is addressed as "you". "Licensees" and\r
+"recipients" may be individuals or organizations.\r
+\r
+ To "modify" a work means to copy from or adapt all or part of the work\r
+in a fashion requiring copyright permission, other than the making of an\r
+exact copy. The resulting work is called a "modified version" of the\r
+earlier work or a work "based on" the earlier work.\r
+\r
+ A "covered work" means either the unmodified Program or a work based\r
+on the Program.\r
+\r
+ To "propagate" a work means to do anything with it that, without\r
+permission, would make you directly or secondarily liable for\r
+infringement under applicable copyright law, except executing it on a\r
+computer or modifying a private copy. Propagation includes copying,\r
+distribution (with or without modification), making available to the\r
+public, and in some countries other activities as well.\r
+\r
+ To "convey" a work means any kind of propagation that enables other\r
+parties to make or receive copies. Mere interaction with a user through\r
+a computer network, with no transfer of a copy, is not conveying.\r
+\r
+ An interactive user interface displays "Appropriate Legal Notices"\r
+to the extent that it includes a convenient and prominently visible\r
+feature that (1) displays an appropriate copyright notice, and (2)\r
+tells the user that there is no warranty for the work (except to the\r
+extent that warranties are provided), that licensees may convey the\r
+work under this License, and how to view a copy of this License. If\r
+the interface presents a list of user commands or options, such as a\r
+menu, a prominent item in the list meets this criterion.\r
+\r
+ 1. Source Code.\r
+\r
+ The "source code" for a work means the preferred form of the work\r
+for making modifications to it. "Object code" means any non-source\r
+form of a work.\r
+\r
+ A "Standard Interface" means an interface that either is an official\r
+standard defined by a recognized standards body, or, in the case of\r
+interfaces specified for a particular programming language, one that\r
+is widely used among developers working in that language.\r
+\r
+ The "System Libraries" of an executable work include anything, other\r
+than the work as a whole, that (a) is included in the normal form of\r
+packaging a Major Component, but which is not part of that Major\r
+Component, and (b) serves only to enable use of the work with that\r
+Major Component, or to implement a Standard Interface for which an\r
+implementation is available to the public in source code form. A\r
+"Major Component", in this context, means a major essential component\r
+(kernel, window system, and so on) of the specific operating system\r
+(if any) on which the executable work runs, or a compiler used to\r
+produce the work, or an object code interpreter used to run it.\r
+\r
+ The "Corresponding Source" for a work in object code form means all\r
+the source code needed to generate, install, and (for an executable\r
+work) run the object code and to modify the work, including scripts to\r
+control those activities. However, it does not include the work's\r
+System Libraries, or general-purpose tools or generally available free\r
+programs which are used unmodified in performing those activities but\r
+which are not part of the work. For example, Corresponding Source\r
+includes interface definition files associated with source files for\r
+the work, and the source code for shared libraries and dynamically\r
+linked subprograms that the work is specifically designed to require,\r
+such as by intimate data communication or control flow between those\r
+subprograms and other parts of the work.\r
+\r
+ The Corresponding Source need not include anything that users\r
+can regenerate automatically from other parts of the Corresponding\r
+Source.\r
+\r
+ The Corresponding Source for a work in source code form is that\r
+same work.\r
+\r
+ 2. Basic Permissions.\r
+\r
+ All rights granted under this License are granted for the term of\r
+copyright on the Program, and are irrevocable provided the stated\r
+conditions are met. This License explicitly affirms your unlimited\r
+permission to run the unmodified Program. The output from running a\r
+covered work is covered by this License only if the output, given its\r
+content, constitutes a covered work. This License acknowledges your\r
+rights of fair use or other equivalent, as provided by copyright law.\r
+\r
+ You may make, run and propagate covered works that you do not\r
+convey, without conditions so long as your license otherwise remains\r
+in force. You may convey covered works to others for the sole purpose\r
+of having them make modifications exclusively for you, or provide you\r
+with facilities for running those works, provided that you comply with\r
+the terms of this License in conveying all material for which you do\r
+not control copyright. Those thus making or running the covered works\r
+for you must do so exclusively on your behalf, under your direction\r
+and control, on terms that prohibit them from making any copies of\r
+your copyrighted material outside their relationship with you.\r
+\r
+ Conveying under any other circumstances is permitted solely under\r
+the conditions stated below. Sublicensing is not allowed; section 10\r
+makes it unnecessary.\r
+\r
+ 3. Protecting Users' Legal Rights From Anti-Circumvention Law.\r
+\r
+ No covered work shall be deemed part of an effective technological\r
+measure under any applicable law fulfilling obligations under article\r
+11 of the WIPO copyright treaty adopted on 20 December 1996, or\r
+similar laws prohibiting or restricting circumvention of such\r
+measures.\r
+\r
+ When you convey a covered work, you waive any legal power to forbid\r
+circumvention of technological measures to the extent such circumvention\r
+is effected by exercising rights under this License with respect to\r
+the covered work, and you disclaim any intention to limit operation or\r
+modification of the work as a means of enforcing, against the work's\r
+users, your or third parties' legal rights to forbid circumvention of\r
+technological measures.\r
+\r
+ 4. Conveying Verbatim Copies.\r
+\r
+ You may convey verbatim copies of the Program's source code as you\r
+receive it, in any medium, provided that you conspicuously and\r
+appropriately publish on each copy an appropriate copyright notice;\r
+keep intact all notices stating that this License and any\r
+non-permissive terms added in accord with section 7 apply to the code;\r
+keep intact all notices of the absence of any warranty; and give all\r
+recipients a copy of this License along with the Program.\r
+\r
+ You may charge any price or no price for each copy that you convey,\r
+and you may offer support or warranty protection for a fee.\r
+\r
+ 5. Conveying Modified Source Versions.\r
+\r
+ You may convey a work based on the Program, or the modifications to\r
+produce it from the Program, in the form of source code under the\r
+terms of section 4, provided that you also meet all of these conditions:\r
+\r
+ a) The work must carry prominent notices stating that you modified\r
+ it, and giving a relevant date.\r
+\r
+ b) The work must carry prominent notices stating that it is\r
+ released under this License and any conditions added under section\r
+ 7. This requirement modifies the requirement in section 4 to\r
+ "keep intact all notices".\r
+\r
+ c) You must license the entire work, as a whole, under this\r
+ License to anyone who comes into possession of a copy. This\r
+ License will therefore apply, along with any applicable section 7\r
+ additional terms, to the whole of the work, and all its parts,\r
+ regardless of how they are packaged. This License gives no\r
+ permission to license the work in any other way, but it does not\r
+ invalidate such permission if you have separately received it.\r
+\r
+ d) If the work has interactive user interfaces, each must display\r
+ Appropriate Legal Notices; however, if the Program has interactive\r
+ interfaces that do not display Appropriate Legal Notices, your\r
+ work need not make them do so.\r
+\r
+ A compilation of a covered work with other separate and independent\r
+works, which are not by their nature extensions of the covered work,\r
+and which are not combined with it such as to form a larger program,\r
+in or on a volume of a storage or distribution medium, is called an\r
+"aggregate" if the compilation and its resulting copyright are not\r
+used to limit the access or legal rights of the compilation's users\r
+beyond what the individual works permit. Inclusion of a covered work\r
+in an aggregate does not cause this License to apply to the other\r
+parts of the aggregate.\r
+\r
+ 6. Conveying Non-Source Forms.\r
+\r
+ You may convey a covered work in object code form under the terms\r
+of sections 4 and 5, provided that you also convey the\r
+machine-readable Corresponding Source under the terms of this License,\r
+in one of these ways:\r
+\r
+ a) Convey the object code in, or embodied in, a physical product\r
+ (including a physical distribution medium), accompanied by the\r
+ Corresponding Source fixed on a durable physical medium\r
+ customarily used for software interchange.\r
+\r
+ b) Convey the object code in, or embodied in, a physical product\r
+ (including a physical distribution medium), accompanied by a\r
+ written offer, valid for at least three years and valid for as\r
+ long as you offer spare parts or customer support for that product\r
+ model, to give anyone who possesses the object code either (1) a\r
+ copy of the Corresponding Source for all the software in the\r
+ product that is covered by this License, on a durable physical\r
+ medium customarily used for software interchange, for a price no\r
+ more than your reasonable cost of physically performing this\r
+ conveying of source, or (2) access to copy the\r
+ Corresponding Source from a network server at no charge.\r
+\r
+ c) Convey individual copies of the object code with a copy of the\r
+ written offer to provide the Corresponding Source. This\r
+ alternative is allowed only occasionally and noncommercially, and\r
+ only if you received the object code with such an offer, in accord\r
+ with subsection 6b.\r
+\r
+ d) Convey the object code by offering access from a designated\r
+ place (gratis or for a charge), and offer equivalent access to the\r
+ Corresponding Source in the same way through the same place at no\r
+ further charge. You need not require recipients to copy the\r
+ Corresponding Source along with the object code. If the place to\r
+ copy the object code is a network server, the Corresponding Source\r
+ may be on a different server (operated by you or a third party)\r
+ that supports equivalent copying facilities, provided you maintain\r
+ clear directions next to the object code saying where to find the\r
+ Corresponding Source. Regardless of what server hosts the\r
+ Corresponding Source, you remain obligated to ensure that it is\r
+ available for as long as needed to satisfy these requirements.\r
+\r
+ e) Convey the object code using peer-to-peer transmission, provided\r
+ you inform other peers where the object code and Corresponding\r
+ Source of the work are being offered to the general public at no\r
+ charge under subsection 6d.\r
+\r
+ A separable portion of the object code, whose source code is excluded\r
+from the Corresponding Source as a System Library, need not be\r
+included in conveying the object code work.\r
+\r
+ A "User Product" is either (1) a "consumer product", which means any\r
+tangible personal property which is normally used for personal, family,\r
+or household purposes, or (2) anything designed or sold for incorporation\r
+into a dwelling. In determining whether a product is a consumer product,\r
+doubtful cases shall be resolved in favor of coverage. For a particular\r
+product received by a particular user, "normally used" refers to a\r
+typical or common use of that class of product, regardless of the status\r
+of the particular user or of the way in which the particular user\r
+actually uses, or expects or is expected to use, the product. A product\r
+is a consumer product regardless of whether the product has substantial\r
+commercial, industrial or non-consumer uses, unless such uses represent\r
+the only significant mode of use of the product.\r
+\r
+ "Installation Information" for a User Product means any methods,\r
+procedures, authorization keys, or other information required to install\r
+and execute modified versions of a covered work in that User Product from\r
+a modified version of its Corresponding Source. The information must\r
+suffice to ensure that the continued functioning of the modified object\r
+code is in no case prevented or interfered with solely because\r
+modification has been made.\r
+\r
+ If you convey an object code work under this section in, or with, or\r
+specifically for use in, a User Product, and the conveying occurs as\r
+part of a transaction in which the right of possession and use of the\r
+User Product is transferred to the recipient in perpetuity or for a\r
+fixed term (regardless of how the transaction is characterized), the\r
+Corresponding Source conveyed under this section must be accompanied\r
+by the Installation Information. But this requirement does not apply\r
+if neither you nor any third party retains the ability to install\r
+modified object code on the User Product (for example, the work has\r
+been installed in ROM).\r
+\r
+ The requirement to provide Installation Information does not include a\r
+requirement to continue to provide support service, warranty, or updates\r
+for a work that has been modified or installed by the recipient, or for\r
+the User Product in which it has been modified or installed. Access to a\r
+network may be denied when the modification itself materially and\r
+adversely affects the operation of the network or violates the rules and\r
+protocols for communication across the network.\r
+\r
+ Corresponding Source conveyed, and Installation Information provided,\r
+in accord with this section must be in a format that is publicly\r
+documented (and with an implementation available to the public in\r
+source code form), and must require no special password or key for\r
+unpacking, reading or copying.\r
+\r
+ 7. Additional Terms.\r
+\r
+ "Additional permissions" are terms that supplement the terms of this\r
+License by making exceptions from one or more of its conditions.\r
+Additional permissions that are applicable to the entire Program shall\r
+be treated as though they were included in this License, to the extent\r
+that they are valid under applicable law. If additional permissions\r
+apply only to part of the Program, that part may be used separately\r
+under those permissions, but the entire Program remains governed by\r
+this License without regard to the additional permissions.\r
+\r
+ When you convey a copy of a covered work, you may at your option\r
+remove any additional permissions from that copy, or from any part of\r
+it. (Additional permissions may be written to require their own\r
+removal in certain cases when you modify the work.) You may place\r
+additional permissions on material, added by you to a covered work,\r
+for which you have or can give appropriate copyright permission.\r
+\r
+ Notwithstanding any other provision of this License, for material you\r
+add to a covered work, you may (if authorized by the copyright holders of\r
+that material) supplement the terms of this License with terms:\r
+\r
+ a) Disclaiming warranty or limiting liability differently from the\r
+ terms of sections 15 and 16 of this License; or\r
+\r
+ b) Requiring preservation of specified reasonable legal notices or\r
+ author attributions in that material or in the Appropriate Legal\r
+ Notices displayed by works containing it; or\r
+\r
+ c) Prohibiting misrepresentation of the origin of that material, or\r
+ requiring that modified versions of such material be marked in\r
+ reasonable ways as different from the original version; or\r
+\r
+ d) Limiting the use for publicity purposes of names of licensors or\r
+ authors of the material; or\r
+\r
+ e) Declining to grant rights under trademark law for use of some\r
+ trade names, trademarks, or service marks; or\r
+\r
+ f) Requiring indemnification of licensors and authors of that\r
+ material by anyone who conveys the material (or modified versions of\r
+ it) with contractual assumptions of liability to the recipient, for\r
+ any liability that these contractual assumptions directly impose on\r
+ those licensors and authors.\r
+\r
+ All other non-permissive additional terms are considered "further\r
+restrictions" within the meaning of section 10. If the Program as you\r
+received it, or any part of it, contains a notice stating that it is\r
+governed by this License along with a term that is a further\r
+restriction, you may remove that term. If a license document contains\r
+a further restriction but permits relicensing or conveying under this\r
+License, you may add to a covered work material governed by the terms\r
+of that license document, provided that the further restriction does\r
+not survive such relicensing or conveying.\r
+\r
+ If you add terms to a covered work in accord with this section, you\r
+must place, in the relevant source files, a statement of the\r
+additional terms that apply to those files, or a notice indicating\r
+where to find the applicable terms.\r
+\r
+ Additional terms, permissive or non-permissive, may be stated in the\r
+form of a separately written license, or stated as exceptions;\r
+the above requirements apply either way.\r
+\r
+ 8. Termination.\r
+\r
+ You may not propagate or modify a covered work except as expressly\r
+provided under this License. Any attempt otherwise to propagate or\r
+modify it is void, and will automatically terminate your rights under\r
+this License (including any patent licenses granted under the third\r
+paragraph of section 11).\r
+\r
+ However, if you cease all violation of this License, then your\r
+license from a particular copyright holder is reinstated (a)\r
+provisionally, unless and until the copyright holder explicitly and\r
+finally terminates your license, and (b) permanently, if the copyright\r
+holder fails to notify you of the violation by some reasonable means\r
+prior to 60 days after the cessation.\r
+\r
+ Moreover, your license from a particular copyright holder is\r
+reinstated permanently if the copyright holder notifies you of the\r
+violation by some reasonable means, this is the first time you have\r
+received notice of violation of this License (for any work) from that\r
+copyright holder, and you cure the violation prior to 30 days after\r
+your receipt of the notice.\r
+\r
+ Termination of your rights under this section does not terminate the\r
+licenses of parties who have received copies or rights from you under\r
+this License. If your rights have been terminated and not permanently\r
+reinstated, you do not qualify to receive new licenses for the same\r
+material under section 10.\r
+\r
+ 9. Acceptance Not Required for Having Copies.\r
+\r
+ You are not required to accept this License in order to receive or\r
+run a copy of the Program. Ancillary propagation of a covered work\r
+occurring solely as a consequence of using peer-to-peer transmission\r
+to receive a copy likewise does not require acceptance. However,\r
+nothing other than this License grants you permission to propagate or\r
+modify any covered work. These actions infringe copyright if you do\r
+not accept this License. Therefore, by modifying or propagating a\r
+covered work, you indicate your acceptance of this License to do so.\r
+\r
+ 10. Automatic Licensing of Downstream Recipients.\r
+\r
+ Each time you convey a covered work, the recipient automatically\r
+receives a license from the original licensors, to run, modify and\r
+propagate that work, subject to this License. You are not responsible\r
+for enforcing compliance by third parties with this License.\r
+\r
+ An "entity transaction" is a transaction transferring control of an\r
+organization, or substantially all assets of one, or subdividing an\r
+organization, or merging organizations. If propagation of a covered\r
+work results from an entity transaction, each party to that\r
+transaction who receives a copy of the work also receives whatever\r
+licenses to the work the party's predecessor in interest had or could\r
+give under the previous paragraph, plus a right to possession of the\r
+Corresponding Source of the work from the predecessor in interest, if\r
+the predecessor has it or can get it with reasonable efforts.\r
+\r
+ You may not impose any further restrictions on the exercise of the\r
+rights granted or affirmed under this License. For example, you may\r
+not impose a license fee, royalty, or other charge for exercise of\r
+rights granted under this License, and you may not initiate litigation\r
+(including a cross-claim or counterclaim in a lawsuit) alleging that\r
+any patent claim is infringed by making, using, selling, offering for\r
+sale, or importing the Program or any portion of it.\r
+\r
+ 11. Patents.\r
+\r
+ A "contributor" is a copyright holder who authorizes use under this\r
+License of the Program or a work on which the Program is based. The\r
+work thus licensed is called the contributor's "contributor version".\r
+\r
+ A contributor's "essential patent claims" are all patent claims\r
+owned or controlled by the contributor, whether already acquired or\r
+hereafter acquired, that would be infringed by some manner, permitted\r
+by this License, of making, using, or selling its contributor version,\r
+but do not include claims that would be infringed only as a\r
+consequence of further modification of the contributor version. For\r
+purposes of this definition, "control" includes the right to grant\r
+patent sublicenses in a manner consistent with the requirements of\r
+this License.\r
+\r
+ Each contributor grants you a non-exclusive, worldwide, royalty-free\r
+patent license under the contributor's essential patent claims, to\r
+make, use, sell, offer for sale, import and otherwise run, modify and\r
+propagate the contents of its contributor version.\r
+\r
+ In the following three paragraphs, a "patent license" is any express\r
+agreement or commitment, however denominated, not to enforce a patent\r
+(such as an express permission to practice a patent or covenant not to\r
+sue for patent infringement). To "grant" such a patent license to a\r
+party means to make such an agreement or commitment not to enforce a\r
+patent against the party.\r
+\r
+ If you convey a covered work, knowingly relying on a patent license,\r
+and the Corresponding Source of the work is not available for anyone\r
+to copy, free of charge and under the terms of this License, through a\r
+publicly available network server or other readily accessible means,\r
+then you must either (1) cause the Corresponding Source to be so\r
+available, or (2) arrange to deprive yourself of the benefit of the\r
+patent license for this particular work, or (3) arrange, in a manner\r
+consistent with the requirements of this License, to extend the patent\r
+license to downstream recipients. "Knowingly relying" means you have\r
+actual knowledge that, but for the patent license, your conveying the\r
+covered work in a country, or your recipient's use of the covered work\r
+in a country, would infringe one or more identifiable patents in that\r
+country that you have reason to believe are valid.\r
+\r
+ If, pursuant to or in connection with a single transaction or\r
+arrangement, you convey, or propagate by procuring conveyance of, a\r
+covered work, and grant a patent license to some of the parties\r
+receiving the covered work authorizing them to use, propagate, modify\r
+or convey a specific copy of the covered work, then the patent license\r
+you grant is automatically extended to all recipients of the covered\r
+work and works based on it.\r
+\r
+ A patent license is "discriminatory" if it does not include within\r
+the scope of its coverage, prohibits the exercise of, or is\r
+conditioned on the non-exercise of one or more of the rights that are\r
+specifically granted under this License. You may not convey a covered\r
+work if you are a party to an arrangement with a third party that is\r
+in the business of distributing software, under which you make payment\r
+to the third party based on the extent of your activity of conveying\r
+the work, and under which the third party grants, to any of the\r
+parties who would receive the covered work from you, a discriminatory\r
+patent license (a) in connection with copies of the covered work\r
+conveyed by you (or copies made from those copies), or (b) primarily\r
+for and in connection with specific products or compilations that\r
+contain the covered work, unless you entered into that arrangement,\r
+or that patent license was granted, prior to 28 March 2007.\r
+\r
+ Nothing in this License shall be construed as excluding or limiting\r
+any implied license or other defenses to infringement that may\r
+otherwise be available to you under applicable patent law.\r
+\r
+ 12. No Surrender of Others' Freedom.\r
+\r
+ If conditions are imposed on you (whether by court order, agreement or\r
+otherwise) that contradict the conditions of this License, they do not\r
+excuse you from the conditions of this License. If you cannot convey a\r
+covered work so as to satisfy simultaneously your obligations under this\r
+License and any other pertinent obligations, then as a consequence you may\r
+not convey it at all. For example, if you agree to terms that obligate you\r
+to collect a royalty for further conveying from those to whom you convey\r
+the Program, the only way you could satisfy both those terms and this\r
+License would be to refrain entirely from conveying the Program.\r
+\r
+ 13. Remote Network Interaction; Use with the GNU General Public License.\r
+\r
+ Notwithstanding any other provision of this License, if you modify the\r
+Program, your modified version must prominently offer all users\r
+interacting with it remotely through a computer network (if your version\r
+supports such interaction) an opportunity to receive the Corresponding\r
+Source of your version by providing access to the Corresponding Source\r
+from a network server at no charge, through some standard or customary\r
+means of facilitating copying of software. This Corresponding Source\r
+shall include the Corresponding Source for any work covered by version 3\r
+of the GNU General Public License that is incorporated pursuant to the\r
+following paragraph.\r
+\r
+ Notwithstanding any other provision of this License, you have\r
+permission to link or combine any covered work with a work licensed\r
+under version 3 of the GNU General Public License into a single\r
+combined work, and to convey the resulting work. The terms of this\r
+License will continue to apply to the part which is the covered work,\r
+but the work with which it is combined will remain governed by version\r
+3 of the GNU General Public License.\r
+\r
+ 14. Revised Versions of this License.\r
+\r
+ The Free Software Foundation may publish revised and/or new versions of\r
+the GNU Affero General Public License from time to time. Such new versions\r
+will be similar in spirit to the present version, but may differ in detail to\r
+address new problems or concerns.\r
+\r
+ Each version is given a distinguishing version number. If the\r
+Program specifies that a certain numbered version of the GNU Affero General\r
+Public License "or any later version" applies to it, you have the\r
+option of following the terms and conditions either of that numbered\r
+version or of any later version published by the Free Software\r
+Foundation. If the Program does not specify a version number of the\r
+GNU Affero General Public License, you may choose any version ever published\r
+by the Free Software Foundation.\r
+\r
+ If the Program specifies that a proxy can decide which future\r
+versions of the GNU Affero General Public License can be used, that proxy's\r
+public statement of acceptance of a version permanently authorizes you\r
+to choose that version for the Program.\r
+\r
+ Later license versions may give you additional or different\r
+permissions. However, no additional obligations are imposed on any\r
+author or copyright holder as a result of your choosing to follow a\r
+later version.\r
+\r
+ 15. Disclaimer of Warranty.\r
+\r
+ THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY\r
+APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT\r
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY\r
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,\r
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR\r
+PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM\r
+IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF\r
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.\r
+\r
+ 16. Limitation of Liability.\r
+\r
+ IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\r
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS\r
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY\r
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE\r
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF\r
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD\r
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),\r
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF\r
+SUCH DAMAGES.\r
+\r
+ 17. Interpretation of Sections 15 and 16.\r
+\r
+ If the disclaimer of warranty and limitation of liability provided\r
+above cannot be given local legal effect according to their terms,\r
+reviewing courts shall apply local law that most closely approximates\r
+an absolute waiver of all civil liability in connection with the\r
+Program, unless a warranty or assumption of liability accompanies a\r
+copy of the Program in return for a fee.\r
+\r
+ END OF TERMS AND CONDITIONS\r
+\r
+ How to Apply These Terms to Your New Programs\r
+\r
+ If you develop a new program, and you want it to be of the greatest\r
+possible use to the public, the best way to achieve this is to make it\r
+free software which everyone can redistribute and change under these terms.\r
+\r
+ To do so, attach the following notices to the program. It is safest\r
+to attach them to the start of each source file to most effectively\r
+state the exclusion of warranty; and each file should have at least\r
+the "copyright" line and a pointer to where the full notice is found.\r
+\r
+ <one line to give the program's name and a brief idea of what it does.>\r
+ Copyright (C) <year> <name of author>\r
+\r
+ This program is free software: you can redistribute it and/or modify\r
+ it under the terms of the GNU Affero General Public License as published by\r
+ the Free Software Foundation, either version 3 of the License, or\r
+ (at your option) any later version.\r
+\r
+ This program is distributed in the hope that it will be useful,\r
+ but WITHOUT ANY WARRANTY; without even the implied warranty of\r
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the\r
+ GNU Affero General Public License for more details.\r
+\r
+ You should have received a copy of the GNU Affero General Public License\r
+ along with this program. If not, see <http://www.gnu.org/licenses/>.\r
+\r
+Also add information on how to contact you by electronic and paper mail.\r
+\r
+ If your software can interact with users remotely through a computer\r
+network, you should also make sure that it provides a way for users to\r
+get its source. For example, if your program is a web application, its\r
+interface could display a "Source" link that leads users to an archive\r
+of the code. There are many ways you could offer source, and different\r
+solutions will be better for different programs; see section 13 for the\r
+specific requirements.\r
+\r
+ You should also get your employer (if you work as a programmer) or school,\r
+if any, to sign a "copyright disclaimer" for the program, if necessary.\r
+For more information on this, and how to apply and follow the GNU AGPL, see\r
+<http://www.gnu.org/licenses/>.\r
