    22 \begin{abstract}
    23 The GNU Affero General Public License is a free, copyleft license
    24 for software and other kinds of works, specifically designed to ensure
    25 cooperation with the community in the case of network server software.
    26 
    27 The licenses for most software and other practical works are
    28 designed to take away your freedom to share and change the works.  By
    29 contrast, our General Public Licenses are intended to guarantee your
    30 freedom to share and change all versions of a program--to make sure it
    31 remains free software for all its users.
    32 
    33 When we speak of free software, we are referring to freedom, not
    34 price.  Our General Public Licenses are designed to make sure that you
    35 have the freedom to distribute copies of free software (and charge for
    36 them if you wish), that you receive source code or can get it if you
    37 want it, that you can change the software or use pieces of it in new
    38 free programs, and that you know you can do these things.
    39 
    40 Developers that use our General Public Licenses protect your rights
    41 with two steps: (1) assert copyright on the software, and (2) offer
    42 you this License which gives you legal permission to copy, distribute
    43 and/or modify the software.
    44 
    45 A secondary benefit of defending all users' freedom is that
    46 improvements made in alternate versions of the program, if they
    47 receive widespread use, become available for other developers to
    48 incorporate.  Many developers of free software are heartened and
    49 encouraged by the resulting cooperation.  However, in the case of
    50 software used on network servers, this result may fail to come about.
    51 The GNU General Public License permits making a modified version and
    52 letting the public access it on a server without ever releasing its
    53 source code to the public.
    54 
    55 The GNU Affero General Public License is designed specifically to
    56 ensure that, in such cases, the modified source code becomes available
    57 to the community.  It requires the operator of a network server to
    58 provide the source code of the modified version running there to the
    59 users of that server.  Therefore, public use of a modified version, on
    60 a publicly accessible server, gives the public access to the source
    61 code of the modified version.
    62 
    63 An older license, called the Affero General Public License and
    64 published by Affero, was designed to accomplish similar goals.  This is
    65 a different license, not a version of the Affero GPL, but Affero has
    66 released a new version of the Affero GPL which permits relicensing under
    67 this license.
    68 
    69 The precise terms and conditions for copying, distribution and
    70 modification follow.

    74 {\Large \sc Terms and Conditions}
    75 \end{center}
    76 
    77 
    78 \begin{enumerate}
    79 
    80 \addtocounter{enumi}{-1}
    81 
    82 \item Definitions.
    83 
    84 ``This License'' refers to version 3 of the GNU Affero General Public License.
    85 
    86 ``Copyright'' also means copyright-like laws that apply to other kinds of
    87 works, such as semiconductor masks.
    88 
    89 ``The Program'' refers to any copyrightable work licensed under this
    90 License.  Each licensee is addressed as ``you''.  ``Licensees'' and
    91 ``recipients'' may be individuals or organizations.
    92 
    93 To ``modify'' a work means to copy from or adapt all or part of the work
    94 in a fashion requiring copyright permission, other than the making of an
    95 exact copy.  The resulting work is called a ``modified version'' of the
    96 earlier work or a work ``based on'' the earlier work.
    97 
    98 A ``covered work'' means either the unmodified Program or a work based
    99 on the Program.
   100 
   101 To ``propagate'' a work means to do anything with it that, without
   102 permission, would make you directly or secondarily liable for
   103 infringement under applicable copyright law, except executing it on a
   104 computer or modifying a private copy.  Propagation includes copying,
   105 distribution (with or without modification), making available to the
   106 public, and in some countries other activities as well.
   107 
   108 To ``convey'' a work means any kind of propagation that enables other
   109 parties to make or receive copies.  Mere interaction with a user through
   110 a computer network, with no transfer of a copy, is not conveying.
   111 
   112 An interactive user interface displays ``Appropriate Legal Notices''
   113 to the extent that it includes a convenient and prominently visible
   114 feature that (1) displays an appropriate copyright notice, and (2)
   115 tells the user that there is no warranty for the work (except to the
   116 extent that warranties are provided), that licensees may convey the
   117 work under this License, and how to view a copy of this License.  If
   118 the interface presents a list of user commands or options, such as a
   119 menu, a prominent item in the list meets this criterion.
   120 
   121 \item Source Code.
   122 
   123 The ``source code'' for a work means the preferred form of the work
   124 for making modifications to it.  ``Object code'' means any non-source
   125 form of a work.
   126 
   127 A ``Standard Interface'' means an interface that either is an official
   128 standard defined by a recognized standards body, or, in the case of
   129 interfaces specified for a particular programming language, one that
   130 is widely used among developers working in that language.
   131 
   132 The ``System Libraries'' of an executable work include anything, other
   133 than the work as a whole, that (a) is included in the normal form of
   134 packaging a Major Component, but which is not part of that Major
   135 Component, and (b) serves only to enable use of the work with that
   136 Major Component, or to implement a Standard Interface for which an
   137 implementation is available to the public in source code form.  A
   138 ``Major Component'', in this context, means a major essential component
   139 (kernel, window system, and so on) of the specific operating system
   140 (if any) on which the executable work runs, or a compiler used to
   141 produce the work, or an object code interpreter used to run it.
   142 
   143 The ``Corresponding Source'' for a work in object code form means all
   144 the source code needed to generate, install, and (for an executable
   145 work) run the object code and to modify the work, including scripts to
   146 control those activities.  However, it does not include the work's
   147 System Libraries, or general-purpose tools or generally available free
   148 programs which are used unmodified in performing those activities but
   149 which are not part of the work.  For example, Corresponding Source
   150 includes interface definition files associated with source files for
   151 the work, and the source code for shared libraries and dynamically
   152 linked subprograms that the work is specifically designed to require,
   153 such as by intimate data communication or control flow between those
   154 subprograms and other parts of the work.
   155 
   156 The Corresponding Source need not include anything that users
   157 can regenerate automatically from other parts of the Corresponding
   158 Source.
   159 
   160 The Corresponding Source for a work in source code form is that
   161 same work.
   162 
   163 \item Basic Permissions.
   164 
   165 All rights granted under this License are granted for the term of
   166 copyright on the Program, and are irrevocable provided the stated
   167 conditions are met.  This License explicitly affirms your unlimited
   168 permission to run the unmodified Program.  The output from running a
   169 covered work is covered by this License only if the output, given its
   170 content, constitutes a covered work.  This License acknowledges your
   171 rights of fair use or other equivalent, as provided by copyright law.
   172 
   173 You may make, run and propagate covered works that you do not
   174 convey, without conditions so long as your license otherwise remains
   175 in force.  You may convey covered works to others for the sole purpose
   176 of having them make modifications exclusively for you, or provide you
   177 with facilities for running those works, provided that you comply with
   178 the terms of this License in conveying all material for which you do
   179 not control copyright.  Those thus making or running the covered works
   180 for you must do so exclusively on your behalf, under your direction
   181 and control, on terms that prohibit them from making any copies of
   182 your copyrighted material outside their relationship with you.
   183 
   184 Conveying under any other circumstances is permitted solely under
   185 the conditions stated below.  Sublicensing is not allowed; section 10
   186 makes it unnecessary.
   187 
   188 \item Protecting Users' Legal Rights From Anti-Circumvention Law.
   189 
   190 No covered work shall be deemed part of an effective technological
   191 measure under any applicable law fulfilling obligations under article
   192 11 of the WIPO copyright treaty adopted on 20 December 1996, or
   193 similar laws prohibiting or restricting circumvention of such
   194 measures.
   195 
   196 When you convey a covered work, you waive any legal power to forbid
   197 circumvention of technological measures to the extent such circumvention
   198 is effected by exercising rights under this License with respect to
   199 the covered work, and you disclaim any intention to limit operation or
   200 modification of the work as a means of enforcing, against the work's
   201 users, your or third parties' legal rights to forbid circumvention of
   202 technological measures.
   203 
   204 \item Conveying Verbatim Copies.
   205 
   206 You may convey verbatim copies of the Program's source code as you
   207 receive it, in any medium, provided that you conspicuously and
   208 appropriately publish on each copy an appropriate copyright notice;
   209 keep intact all notices stating that this License and any
   210 non-permissive terms added in accord with section 7 apply to the code;
   211 keep intact all notices of the absence of any warranty; and give all
   212 recipients a copy of this License along with the Program.
   213 
   214 You may charge any price or no price for each copy that you convey,
   215 and you may offer support or warranty protection for a fee.
   216 
   217 \item Conveying Modified Source Versions.
   218 
   219 You may convey a work based on the Program, or the modifications to
   220 produce it from the Program, in the form of source code under the
   221 terms of section 4, provided that you also meet all of these conditions:
   222   \begin{enumerate}
   223   \item The work must carry prominent notices stating that you modified
   224   it, and giving a relevant date.
   225 
   226   \item The work must carry prominent notices stating that it is
   227   released under this License and any conditions added under section
   228   7.  This requirement modifies the requirement in section 4 to
   229   ``keep intact all notices''.
   230 
   231   \item You must license the entire work, as a whole, under this
   232   License to anyone who comes into possession of a copy.  This
   233   License will therefore apply, along with any applicable section 7
   234   additional terms, to the whole of the work, and all its parts,
   235   regardless of how they are packaged.  This License gives no
   236   permission to license the work in any other way, but it does not
   237   invalidate such permission if you have separately received it.
   238 
   239   \item If the work has interactive user interfaces, each must display
   240   Appropriate Legal Notices; however, if the Program has interactive
   241   interfaces that do not display Appropriate Legal Notices, your
   242   work need not make them do so.
   243 \end{enumerate}
   244 A compilation of a covered work with other separate and independent
   245 works, which are not by their nature extensions of the covered work,
   246 and which are not combined with it such as to form a larger program,
   247 in or on a volume of a storage or distribution medium, is called an
   248 ``aggregate'' if the compilation and its resulting copyright are not
   249 used to limit the access or legal rights of the compilation's users
   250 beyond what the individual works permit.  Inclusion of a covered work
   251 in an aggregate does not cause this License to apply to the other
   252 parts of the aggregate.
   253 
   254 \item Conveying Non-Source Forms.
   255 
   256 You may convey a covered work in object code form under the terms
   257 of sections 4 and 5, provided that you also convey the
   258 machine-readable Corresponding Source under the terms of this License,
   259 in one of these ways:
   260   \begin{enumerate}
   261   \item Convey the object code in, or embodied in, a physical product
   262   (including a physical distribution medium), accompanied by the
   263   Corresponding Source fixed on a durable physical medium
   264   customarily used for software interchange.
   265 
   266   \item Convey the object code in, or embodied in, a physical product
   267   (including a physical distribution medium), accompanied by a
   268   written offer, valid for at least three years and valid for as
   269   long as you offer spare parts or customer support for that product
   270   model, to give anyone who possesses the object code either (1) a
   271   copy of the Corresponding Source for all the software in the
   272   product that is covered by this License, on a durable physical
   273   medium customarily used for software interchange, for a price no
   274   more than your reasonable cost of physically performing this
   275   conveying of source, or (2) access to copy the
   276   Corresponding Source from a network server at no charge.
   277 
   278   \item Convey individual copies of the object code with a copy of the
   279   written offer to provide the Corresponding Source.  This
   280   alternative is allowed only occasionally and noncommercially, and
   281   only if you received the object code with such an offer, in accord
   282   with subsection 6b.
   283 
   284   \item Convey the object code by offering access from a designated
   285   place (gratis or for a charge), and offer equivalent access to the
   286   Corresponding Source in the same way through the same place at no
   287   further charge.  You need not require recipients to copy the
   288   Corresponding Source along with the object code.  If the place to
   289   copy the object code is a network server, the Corresponding Source
   290   may be on a different server (operated by you or a third party)
   291   that supports equivalent copying facilities, provided you maintain
   292   clear directions next to the object code saying where to find the
   293   Corresponding Source.  Regardless of what server hosts the
   294   Corresponding Source, you remain obligated to ensure that it is
   295   available for as long as needed to satisfy these requirements.
   296 
   297   \item Convey the object code using peer-to-peer transmission, provided
   298   you inform other peers where the object code and Corresponding
   299   Source of the work are being offered to the general public at no
   300   charge under subsection 6d.
   301   \end{enumerate}
   302 
   303 A separable portion of the object code, whose source code is excluded
   304 from the Corresponding Source as a System Library, need not be
   305 included in conveying the object code work.
   306 
   307 A ``User Product'' is either (1) a ``consumer product'', which means any
   308 tangible personal property which is normally used for personal, family,
   309 or household purposes, or (2) anything designed or sold for incorporation
   310 into a dwelling.  In determining whether a product is a consumer product,
   311 doubtful cases shall be resolved in favor of coverage.  For a particular
   312 product received by a particular user, ``normally used'' refers to a
   313 typical or common use of that class of product, regardless of the status
   314 of the particular user or of the way in which the particular user
   315 actually uses, or expects or is expected to use, the product.  A product
   316 is a consumer product regardless of whether the product has substantial
   317 commercial, industrial or non-consumer uses, unless such uses represent
   318 the only significant mode of use of the product.
   319 
   320 ``Installation Information'' for a User Product means any methods,
   321 procedures, authorization keys, or other information required to install
   322 and execute modified versions of a covered work in that User Product from
   323 a modified version of its Corresponding Source.  The information must
   324 suffice to ensure that the continued functioning of the modified object
   325 code is in no case prevented or interfered with solely because
   326 modification has been made.
   327 
   328 If you convey an object code work under this section in, or with, or
   329 specifically for use in, a User Product, and the conveying occurs as
   330 part of a transaction in which the right of possession and use of the
   331 User Product is transferred to the recipient in perpetuity or for a
   332 fixed term (regardless of how the transaction is characterized), the
   333 Corresponding Source conveyed under this section must be accompanied
   334 by the Installation Information.  But this requirement does not apply
   335 if neither you nor any third party retains the ability to install
   336 modified object code on the User Product (for example, the work has
   337 been installed in ROM).
   338 
   339 The requirement to provide Installation Information does not include a
   340 requirement to continue to provide support service, warranty, or updates
   341 for a work that has been modified or installed by the recipient, or for
   342 the User Product in which it has been modified or installed.  Access to a
   343 network may be denied when the modification itself materially and
   344 adversely affects the operation of the network or violates the rules and
   345 protocols for communication across the network.
   346 
   347 Corresponding Source conveyed, and Installation Information provided,
   348 in accord with this section must be in a format that is publicly
   349 documented (and with an implementation available to the public in
   350 source code form), and must require no special password or key for
   351 unpacking, reading or copying.
   352 
   353 \item Additional Terms.
   354 
   355 ``Additional permissions'' are terms that supplement the terms of this
   356 License by making exceptions from one or more of its conditions.
   357 Additional permissions that are applicable to the entire Program shall
   358 be treated as though they were included in this License, to the extent
   359 that they are valid under applicable law.  If additional permissions
   360 apply only to part of the Program, that part may be used separately
   361 under those permissions, but the entire Program remains governed by
   362 this License without regard to the additional permissions.
   363 
   364 When you convey a copy of a covered work, you may at your option
   365 remove any additional permissions from that copy, or from any part of
   366 it.  (Additional permissions may be written to require their own
   367 removal in certain cases when you modify the work.)  You may place
   368 additional permissions on material, added by you to a covered work,
   369 for which you have or can give appropriate copyright permission.
   370 
   371 Notwithstanding any other provision of this License, for material you
   372 add to a covered work, you may (if authorized by the copyright holders of
   373 that material) supplement the terms of this License with terms:
   374   \begin{enumerate}
   375   \item Disclaiming warranty or limiting liability differently from the
   376   terms of sections 15 and 16 of this License; or
   377 
   378   \item Requiring preservation of specified reasonable legal notices or
   379   author attributions in that material or in the Appropriate Legal
   380   Notices displayed by works containing it; or
   381 
   382   \item Prohibiting misrepresentation of the origin of that material, or
   383   requiring that modified versions of such material be marked in
   384   reasonable ways as different from the original version; or
   385 
   386   \item Limiting the use for publicity purposes of names of licensors or
   387   authors of the material; or
   388 
   389   \item Declining to grant rights under trademark law for use of some
   390   trade names, trademarks, or service marks; or
   391 
   392   \item Requiring indemnification of licensors and authors of that
   393   material by anyone who conveys the material (or modified versions of
   394   it) with contractual assumptions of liability to the recipient, for
   395   any liability that these contractual assumptions directly impose on
   396   those licensors and authors.
   397   \end{enumerate}
   398 
   399 All other non-permissive additional terms are considered ``further
   400 restrictions'' within the meaning of section 10.  If the Program as you
   401 received it, or any part of it, contains a notice stating that it is
   402 governed by this License along with a term that is a further
   403 restriction, you may remove that term.  If a license document contains
   404 a further restriction but permits relicensing or conveying under this
   405 License, you may add to a covered work material governed by the terms
   406 of that license document, provided that the further restriction does
   407 not survive such relicensing or conveying.
   408 
   409 If you add terms to a covered work in accord with this section, you
   410 must place, in the relevant source files, a statement of the
   411 additional terms that apply to those files, or a notice indicating
   412 where to find the applicable terms.
   413 
   414 Additional terms, permissive or non-permissive, may be stated in the
   415 form of a separately written license, or stated as exceptions;
   416 the above requirements apply either way.
   417 
   418 \item Termination.
   419 
   420 You may not propagate or modify a covered work except as expressly
   421 provided under this License.  Any attempt otherwise to propagate or
   422 modify it is void, and will automatically terminate your rights under
   423 this License (including any patent licenses granted under the third
   424 paragraph of section 11).
   425 
   426 However, if you cease all violation of this License, then your
   427 license from a particular copyright holder is reinstated (a)
   428 provisionally, unless and until the copyright holder explicitly and
   429 finally terminates your license, and (b) permanently, if the copyright
   430 holder fails to notify you of the violation by some reasonable means
   431 prior to 60 days after the cessation.
   432 
   433 Moreover, your license from a particular copyright holder is
   434 reinstated permanently if the copyright holder notifies you of the
   435 violation by some reasonable means, this is the first time you have
   436 received notice of violation of this License (for any work) from that
   437 copyright holder, and you cure the violation prior to 30 days after
   438 your receipt of the notice.
   439 
   440 Termination of your rights under this section does not terminate the
   441 licenses of parties who have received copies or rights from you under
   442 this License.  If your rights have been terminated and not permanently
   443 reinstated, you do not qualify to receive new licenses for the same
   444 material under section 10.
   445 
   446 \item Acceptance Not Required for Having Copies.
   447 
   448 You are not required to accept this License in order to receive or
   449 run a copy of the Program.  Ancillary propagation of a covered work
   450 occurring solely as a consequence of using peer-to-peer transmission
   451 to receive a copy likewise does not require acceptance.  However,
   452 nothing other than this License grants you permission to propagate or
   453 modify any covered work.  These actions infringe copyright if you do
   454 not accept this License.  Therefore, by modifying or propagating a
   455 covered work, you indicate your acceptance of this License to do so.
   456 
   457 \item Automatic Licensing of Downstream Recipients.
   458 
   459 Each time you convey a covered work, the recipient automatically
   460 receives a license from the original licensors, to run, modify and
   461 propagate that work, subject to this License.  You are not responsible
   462 for enforcing compliance by third parties with this License.
   463 
   464 An ``entity transaction'' is a transaction transferring control of an
   465 organization, or substantially all assets of one, or subdividing an
   466 organization, or merging organizations.  If propagation of a covered
   467 work results from an entity transaction, each party to that
   468 transaction who receives a copy of the work also receives whatever
   469 licenses to the work the party's predecessor in interest had or could
   470 give under the previous paragraph, plus a right to possession of the
   471 Corresponding Source of the work from the predecessor in interest, if
   472 the predecessor has it or can get it with reasonable efforts.
   473 
   474 You may not impose any further restrictions on the exercise of the
   475 rights granted or affirmed under this License.  For example, you may
   476 not impose a license fee, royalty, or other charge for exercise of
   477 rights granted under this License, and you may not initiate litigation
   478 (including a cross-claim or counterclaim in a lawsuit) alleging that
   479 any patent claim is infringed by making, using, selling, offering for
   480 sale, or importing the Program or any portion of it.
   481 
   482 \item Patents.
   483 
   484 A ``contributor'' is a copyright holder who authorizes use under this
   485 License of the Program or a work on which the Program is based.  The
   486 work thus licensed is called the contributor's ``contributor version''.
   487 
   488 A contributor's ``essential patent claims'' are all patent claims
   489 owned or controlled by the contributor, whether already acquired or
   490 hereafter acquired, that would be infringed by some manner, permitted
   491 by this License, of making, using, or selling its contributor version,
   492 but do not include claims that would be infringed only as a
   493 consequence of further modification of the contributor version.  For
   494 purposes of this definition, ``control'' includes the right to grant
   495 patent sublicenses in a manner consistent with the requirements of
   496 this License.
   497 
   498 Each contributor grants you a non-exclusive, worldwide, royalty-free
   499 patent license under the contributor's essential patent claims, to
   500 make, use, sell, offer for sale, import and otherwise run, modify and
   501 propagate the contents of its contributor version.
   502 
   503 In the following three paragraphs, a ``patent license'' is any express
   504 agreement or commitment, however denominated, not to enforce a patent
   505 (such as an express permission to practice a patent or covenant not to
   506 sue for patent infringement).  To ``grant'' such a patent license to a
   507 party means to make such an agreement or commitment not to enforce a
   508 patent against the party.
   509 
   510 If you convey a covered work, knowingly relying on a patent license,
   511 and the Corresponding Source of the work is not available for anyone
   512 to copy, free of charge and under the terms of this License, through a
   513 publicly available network server or other readily accessible means,
   514 then you must either (1) cause the Corresponding Source to be so
   515 available, or (2) arrange to deprive yourself of the benefit of the
   516 patent license for this particular work, or (3) arrange, in a manner
   517 consistent with the requirements of this License, to extend the patent
   518 license to downstream recipients.  ``Knowingly relying'' means you have
   519 actual knowledge that, but for the patent license, your conveying the
   520 covered work in a country, or your recipient's use of the covered work
   521 in a country, would infringe one or more identifiable patents in that
   522 country that you have reason to believe are valid.
   523 
   524 If, pursuant to or in connection with a single transaction or
   525 arrangement, you convey, or propagate by procuring conveyance of, a
   526 covered work, and grant a patent license to some of the parties
   527 receiving the covered work authorizing them to use, propagate, modify
   528 or convey a specific copy of the covered work, then the patent license
   529 you grant is automatically extended to all recipients of the covered
   530 work and works based on it.
   531 
   532 A patent license is ``discriminatory'' if it does not include within
   533 the scope of its coverage, prohibits the exercise of, or is
   534 conditioned on the non-exercise of one or more of the rights that are
   535 specifically granted under this License.  You may not convey a covered
   536 work if you are a party to an arrangement with a third party that is
   537 in the business of distributing software, under which you make payment
   538 to the third party based on the extent of your activity of conveying
   539 the work, and under which the third party grants, to any of the
   540 parties who would receive the covered work from you, a discriminatory
   541 patent license (a) in connection with copies of the covered work
   542 conveyed by you (or copies made from those copies), or (b) primarily
   543 for and in connection with specific products or compilations that
   544 contain the covered work, unless you entered into that arrangement,
   545 or that patent license was granted, prior to 28 March 2007.
   546 
   547 Nothing in this License shall be construed as excluding or limiting
   548 any implied license or other defenses to infringement that may
   549 otherwise be available to you under applicable patent law.
   550 
   551 \item No Surrender of Others' Freedom.
   552 
   553 If conditions are imposed on you (whether by court order, agreement or
   554 otherwise) that contradict the conditions of this License, they do not
   555 excuse you from the conditions of this License.  If you cannot convey a
   556 covered work so as to satisfy simultaneously your obligations under this
   557 License and any other pertinent obligations, then as a consequence you may
   558 not convey it at all.  For example, if you agree to terms that obligate you
   559 to collect a royalty for further conveying from those to whom you convey
   560 the Program, the only way you could satisfy both those terms and this
   561 License would be to refrain entirely from conveying the Program.
   562 
   563 \item Remote Network Interaction; Use with the GNU General Public License.
   564 
   565 Notwithstanding any other provision of this License, if you modify the
   566 Program, your modified version must prominently offer all users interacting
   567 with it remotely through a computer network (if your version supports such
   568 interaction) an opportunity to receive the Corresponding Source of your
   569 version by providing access to the Corresponding Source from a network
   570 server at no charge, through some standard or customary means of
   571 facilitating copying of software.  This Corresponding Source shall include
   572 the Corresponding Source for any work covered by version 3 of the GNU
   573 General Public License that is incorporated pursuant to the following
   574 paragraph.
   575 
   576 Notwithstanding any other provision of this License, you have permission to
   577 link or combine any covered work with a work licensed under version 3 of
   578 the GNU General Public License into a single combined work, and to convey
   579 the resulting work.  The terms of this License will continue to apply to
   580 the part which is the covered work, but the work with which it is combined
   581 will remain governed by version 3 of the GNU General Public License.
   582 
   583 \item Revised Versions of this License.
   584 
   585 The Free Software Foundation may publish revised and/or new versions of
   586 the GNU Affero General Public License from time to time.  Such new versions will
   587 be similar in spirit to the present version, but may differ in detail to
   588 address new problems or concerns.
   589 
   590 Each version is given a distinguishing version number.  If the
   591 Program specifies that a certain numbered version of the GNU Affero General
   592 Public License ``or any later version'' applies to it, you have the
   593 option of following the terms and conditions either of that numbered
   594 version or of any later version published by the Free Software
   595 Foundation.  If the Program does not specify a version number of the
   596 GNU Affero General Public License, you may choose any version ever published
   597 by the Free Software Foundation.
   598 
   599 If the Program specifies that a proxy can decide which future
   600 versions of the GNU Affero General Public License can be used, that proxy's
   601 public statement of acceptance of a version permanently authorizes you
   602 to choose that version for the Program.
   603 
   604 Later license versions may give you additional or different
   605 permissions.  However, no additional obligations are imposed on any
   606 author or copyright holder as a result of your choosing to follow a
   607 later version.
   608 
   609 \item Disclaimer of Warranty.
   610 
   611 \begin{sloppypar}
   612  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
   613  APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE
   614  COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS''
   615  WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
   616  INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
   617  MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE
   618  RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
   619  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
   620  NECESSARY SERVICING, REPAIR OR CORRECTION.
   621 \end{sloppypar}
   622 
   623 \item Limitation of Liability.
   624 
   625  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
   626  WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
   627  AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
   628  DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
   629  DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
   630  (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
   631  INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE
   632  OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
   633  HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
   634  DAMAGES.
   635 
   636 \item Interpretation of Sections 15 and 16.
   637 
   638 If the disclaimer of warranty and limitation of liability provided
   639 above cannot be given local legal effect according to their terms,
   640 reviewing courts shall apply local law that most closely approximates
   641 an absolute waiver of all civil liability in connection with the
   642 Program, unless a warranty or assumption of liability accompanies a
   643 copy of the Program in return for a fee.

   649 How to Apply These Terms to Your New Programs
   650 \end{center}
   651 
   652 If you develop a new program, and you want it to be of the greatest
   653 possible use to the public, the best way to achieve this is to make it
   654 free software which everyone can redistribute and change under these terms.
   655 
   656 To do so, attach the following notices to the program.  It is safest
   657 to attach them to the start of each source file to most effectively
   658 state the exclusion of warranty; and each file should have at least
   659 the ``copyright'' line and a pointer to where the full notice is found.
   660 
   661 {\footnotesize
   662 \begin{verbatim}
   663 <one line to give the program's name and a brief idea of what it does.>
   664 
   665 Copyright (C) <textyear>  <name of author>
   666 
   667 This program is free software: you can redistribute it and/or modify
   668 it under the terms of the GNU Affero General Public License as published by
   669 the Free Software Foundation, either version 3 of the License, or
   670 (at your option) any later version.
   671 
   672 This program is distributed in the hope that it will be useful,
   673 but WITHOUT ANY WARRANTY; without even the implied warranty of
   674 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
   675 GNU Affero General Public License for more details.
   676 
   677 You should have received a copy of the GNU Affero General Public License
   678 along with this program.  If not, see <http://www.gnu.org/licenses/>.
   679 \end{verbatim}
   680 }
   681 
   682 Also add information on how to contact you by electronic and paper mail.
   683 
   684 If your software can interact with users remotely through a computer
   685 network, you should also make sure that it provides a way for users to
   686 get its source.  For example, if your program is a web application, its
   687 interface could display a ``Source'' link that leads users to an archive
   688 of the code.  There are many ways you could offer source, and different
   689 solutions will be better for different programs; see section 13 for the
   690 specific requirements.
   691 
   692 You should also get your employer (if you work as a programmer) or
   693 school, if any, to sign a ``copyright disclaimer'' for the program, if
   694 necessary.  For more information on this, and how to apply and follow
   695 the GNU AGPL, see \texttt{http://www.gnu.org/licenses/}.
