1.25 +\begin{abstract}
1.26 +The GNU Affero General Public License is a free, copyleft license
1.27 +for software and other kinds of works, specifically designed to ensure
1.28 +cooperation with the community in the case of network server software.
1.29 +
1.30 +The licenses for most software and other practical works are
1.31 +designed to take away your freedom to share and change the works. By
1.32 +contrast, our General Public Licenses are intended to guarantee your
1.33 +freedom to share and change all versions of a program--to make sure it
1.34 +remains free software for all its users.
1.35 +
1.36 +When we speak of free software, we are referring to freedom, not
1.37 +price. Our General Public Licenses are designed to make sure that you
1.38 +have the freedom to distribute copies of free software (and charge for
1.39 +them if you wish), that you receive source code or can get it if you
1.40 +want it, that you can change the software or use pieces of it in new
1.41 +free programs, and that you know you can do these things.
1.42 +
1.43 +Developers that use our General Public Licenses protect your rights
1.44 +with two steps: (1) assert copyright on the software, and (2) offer
1.45 +you this License which gives you legal permission to copy, distribute
1.46 +and/or modify the software.
1.47 +
1.48 +A secondary benefit of defending all users' freedom is that
1.49 +improvements made in alternate versions of the program, if they
1.50 +receive widespread use, become available for other developers to
1.51 +incorporate. Many developers of free software are heartened and
1.52 +encouraged by the resulting cooperation. However, in the case of
1.53 +software used on network servers, this result may fail to come about.
1.54 +The GNU General Public License permits making a modified version and
1.55 +letting the public access it on a server without ever releasing its
1.56 +source code to the public.
1.57 +
1.58 +The GNU Affero General Public License is designed specifically to
1.59 +ensure that, in such cases, the modified source code becomes available
1.60 +to the community. It requires the operator of a network server to
1.61 +provide the source code of the modified version running there to the
1.62 +users of that server. Therefore, public use of a modified version, on
1.63 +a publicly accessible server, gives the public access to the source
1.64 +code of the modified version.
1.65 +
1.66 +An older license, called the Affero General Public License and
1.67 +published by Affero, was designed to accomplish similar goals. This is
1.68 +a different license, not a version of the Affero GPL, but Affero has
1.69 +released a new version of the Affero GPL which permits relicensing under
1.70 +this license.
1.71 +
1.72 +The precise terms and conditions for copying, distribution and
1.73 +modification follow.

1.75 +
1.76 +\begin{center}
1.77 +{\Large \sc Terms and Conditions}
1.78 +\end{center}
1.79 +
1.80 +
1.81 +\begin{enumerate}
1.82 +
1.83 +\addtocounter{enumi}{-1}
1.84 +
1.85 +\item Definitions.
1.86 +
1.87 +``This License'' refers to version 3 of the GNU Affero General Public License.
1.88 +
1.89 +``Copyright'' also means copyright-like laws that apply to other kinds of
1.90 +works, such as semiconductor masks.
1.91 +
1.92 +``The Program'' refers to any copyrightable work licensed under this
1.93 +License. Each licensee is addressed as ``you''. ``Licensees'' and
1.94 +``recipients'' may be individuals or organizations.
1.95 +
1.96 +To ``modify'' a work means to copy from or adapt all or part of the work
1.97 +in a fashion requiring copyright permission, other than the making of an
1.98 +exact copy. The resulting work is called a ``modified version'' of the
1.99 +earlier work or a work ``based on'' the earlier work.
1.100 +
1.101 +A ``covered work'' means either the unmodified Program or a work based
1.102 +on the Program.
1.103 +
1.104 +To ``propagate'' a work means to do anything with it that, without
1.105 +permission, would make you directly or secondarily liable for
1.106 +infringement under applicable copyright law, except executing it on a
1.107 +computer or modifying a private copy. Propagation includes copying,
1.108 +distribution (with or without modification), making available to the
1.109 +public, and in some countries other activities as well.
1.110 +
1.111 +To ``convey'' a work means any kind of propagation that enables other
1.112 +parties to make or receive copies. Mere interaction with a user through
1.113 +a computer network, with no transfer of a copy, is not conveying.
1.114 +
1.115 +An interactive user interface displays ``Appropriate Legal Notices''
1.116 +to the extent that it includes a convenient and prominently visible
1.117 +feature that (1) displays an appropriate copyright notice, and (2)
1.118 +tells the user that there is no warranty for the work (except to the
1.119 +extent that warranties are provided), that licensees may convey the
1.120 +work under this License, and how to view a copy of this License. If
1.121 +the interface presents a list of user commands or options, such as a
1.122 +menu, a prominent item in the list meets this criterion.
1.123 +
1.124 +\item Source Code.
1.125 +
1.126 +The ``source code'' for a work means the preferred form of the work
1.127 +for making modifications to it. ``Object code'' means any non-source
1.128 +form of a work.
1.129 +
1.130 +A ``Standard Interface'' means an interface that either is an official
1.131 +standard defined by a recognized standards body, or, in the case of
1.132 +interfaces specified for a particular programming language, one that
1.133 +is widely used among developers working in that language.
1.134 +
1.135 +The ``System Libraries'' of an executable work include anything, other
1.136 +than the work as a whole, that (a) is included in the normal form of
1.137 +packaging a Major Component, but which is not part of that Major
1.138 +Component, and (b) serves only to enable use of the work with that
1.139 +Major Component, or to implement a Standard Interface for which an
1.140 +implementation is available to the public in source code form. A
1.141 +``Major Component'', in this context, means a major essential component
1.142 +(kernel, window system, and so on) of the specific operating system
1.143 +(if any) on which the executable work runs, or a compiler used to
1.144 +produce the work, or an object code interpreter used to run it.
1.145 +
1.146 +The ``Corresponding Source'' for a work in object code form means all
1.147 +the source code needed to generate, install, and (for an executable
1.148 +work) run the object code and to modify the work, including scripts to
1.149 +control those activities. However, it does not include the work's
1.150 +System Libraries, or general-purpose tools or generally available free
1.151 +programs which are used unmodified in performing those activities but
1.152 +which are not part of the work. For example, Corresponding Source
1.153 +includes interface definition files associated with source files for
1.154 +the work, and the source code for shared libraries and dynamically
1.155 +linked subprograms that the work is specifically designed to require,
1.156 +such as by intimate data communication or control flow between those
1.157 +subprograms and other parts of the work.
1.158 +
1.159 +The Corresponding Source need not include anything that users
1.160 +can regenerate automatically from other parts of the Corresponding
1.161 +Source.
1.162 +
1.163 +The Corresponding Source for a work in source code form is that
1.164 +same work.
1.165 +
1.166 +\item Basic Permissions.
1.167 +
1.168 +All rights granted under this License are granted for the term of
1.169 +copyright on the Program, and are irrevocable provided the stated
1.170 +conditions are met. This License explicitly affirms your unlimited
1.171 +permission to run the unmodified Program. The output from running a
1.172 +covered work is covered by this License only if the output, given its
1.173 +content, constitutes a covered work. This License acknowledges your
1.174 +rights of fair use or other equivalent, as provided by copyright law.
1.175 +
1.176 +You may make, run and propagate covered works that you do not
1.177 +convey, without conditions so long as your license otherwise remains
1.178 +in force. You may convey covered works to others for the sole purpose
1.179 +of having them make modifications exclusively for you, or provide you
1.180 +with facilities for running those works, provided that you comply with
1.181 +the terms of this License in conveying all material for which you do
1.182 +not control copyright. Those thus making or running the covered works
1.183 +for you must do so exclusively on your behalf, under your direction
1.184 +and control, on terms that prohibit them from making any copies of
1.185 +your copyrighted material outside their relationship with you.
1.186 +
1.187 +Conveying under any other circumstances is permitted solely under
1.188 +the conditions stated below. Sublicensing is not allowed; section 10
1.189 +makes it unnecessary.
1.190 +
1.191 +\item Protecting Users' Legal Rights From Anti-Circumvention Law.
1.192 +
1.193 +No covered work shall be deemed part of an effective technological
1.194 +measure under any applicable law fulfilling obligations under article
1.195 +11 of the WIPO copyright treaty adopted on 20 December 1996, or
1.196 +similar laws prohibiting or restricting circumvention of such
1.197 +measures.
1.198 +
1.199 +When you convey a covered work, you waive any legal power to forbid
1.200 +circumvention of technological measures to the extent such circumvention
1.201 +is effected by exercising rights under this License with respect to
1.202 +the covered work, and you disclaim any intention to limit operation or
1.203 +modification of the work as a means of enforcing, against the work's
1.204 +users, your or third parties' legal rights to forbid circumvention of
1.205 +technological measures.
1.206 +
1.207 +\item Conveying Verbatim Copies.
1.208 +
1.209 +You may convey verbatim copies of the Program's source code as you
1.210 +receive it, in any medium, provided that you conspicuously and
1.211 +appropriately publish on each copy an appropriate copyright notice;
1.212 +keep intact all notices stating that this License and any
1.213 +non-permissive terms added in accord with section 7 apply to the code;
1.214 +keep intact all notices of the absence of any warranty; and give all
1.215 +recipients a copy of this License along with the Program.
1.216 +
1.217 +You may charge any price or no price for each copy that you convey,
1.218 +and you may offer support or warranty protection for a fee.
1.219 +
1.220 +\item Conveying Modified Source Versions.
1.221 +
1.222 +You may convey a work based on the Program, or the modifications to
1.223 +produce it from the Program, in the form of source code under the
1.224 +terms of section 4, provided that you also meet all of these conditions:
1.225 + \begin{enumerate}
1.226 + \item The work must carry prominent notices stating that you modified
1.227 + it, and giving a relevant date.
1.228 +
1.229 + \item The work must carry prominent notices stating that it is
1.230 + released under this License and any conditions added under section
1.231 + 7. This requirement modifies the requirement in section 4 to
1.232 + ``keep intact all notices''.
1.233 +
1.234 + \item You must license the entire work, as a whole, under this
1.235 + License to anyone who comes into possession of a copy. This
1.236 + License will therefore apply, along with any applicable section 7
1.237 + additional terms, to the whole of the work, and all its parts,
1.238 + regardless of how they are packaged. This License gives no
1.239 + permission to license the work in any other way, but it does not
1.240 + invalidate such permission if you have separately received it.
1.241 +
1.242 + \item If the work has interactive user interfaces, each must display
1.243 + Appropriate Legal Notices; however, if the Program has interactive
1.244 + interfaces that do not display Appropriate Legal Notices, your
1.245 + work need not make them do so.
1.246 +\end{enumerate}
1.247 +A compilation of a covered work with other separate and independent
1.248 +works, which are not by their nature extensions of the covered work,
1.249 +and which are not combined with it such as to form a larger program,
1.250 +in or on a volume of a storage or distribution medium, is called an
1.251 +``aggregate'' if the compilation and its resulting copyright are not
1.252 +used to limit the access or legal rights of the compilation's users
1.253 +beyond what the individual works permit. Inclusion of a covered work
1.254 +in an aggregate does not cause this License to apply to the other
1.255 +parts of the aggregate.
1.256 +
1.257 +\item Conveying Non-Source Forms.
1.258 +
1.259 +You may convey a covered work in object code form under the terms
1.260 +of sections 4 and 5, provided that you also convey the
1.261 +machine-readable Corresponding Source under the terms of this License,
1.262 +in one of these ways:
1.263 + \begin{enumerate}
1.264 + \item Convey the object code in, or embodied in, a physical product
1.265 + (including a physical distribution medium), accompanied by the
1.266 + Corresponding Source fixed on a durable physical medium
1.267 + customarily used for software interchange.
1.268 +
1.269 + \item Convey the object code in, or embodied in, a physical product
1.270 + (including a physical distribution medium), accompanied by a
1.271 + written offer, valid for at least three years and valid for as
1.272 + long as you offer spare parts or customer support for that product
1.273 + model, to give anyone who possesses the object code either (1) a
1.274 + copy of the Corresponding Source for all the software in the
1.275 + product that is covered by this License, on a durable physical
1.276 + medium customarily used for software interchange, for a price no
1.277 + more than your reasonable cost of physically performing this
1.278 + conveying of source, or (2) access to copy the
1.279 + Corresponding Source from a network server at no charge.
1.280 +
1.281 + \item Convey individual copies of the object code with a copy of the
1.282 + written offer to provide the Corresponding Source. This
1.283 + alternative is allowed only occasionally and noncommercially, and
1.284 + only if you received the object code with such an offer, in accord
1.285 + with subsection 6b.
1.286 +
1.287 + \item Convey the object code by offering access from a designated
1.288 + place (gratis or for a charge), and offer equivalent access to the
1.289 + Corresponding Source in the same way through the same place at no
1.290 + further charge. You need not require recipients to copy the
1.291 + Corresponding Source along with the object code. If the place to
1.292 + copy the object code is a network server, the Corresponding Source
1.293 + may be on a different server (operated by you or a third party)
1.294 + that supports equivalent copying facilities, provided you maintain
1.295 + clear directions next to the object code saying where to find the
1.296 + Corresponding Source. Regardless of what server hosts the
1.297 + Corresponding Source, you remain obligated to ensure that it is
1.298 + available for as long as needed to satisfy these requirements.
1.299 +
1.300 + \item Convey the object code using peer-to-peer transmission, provided
1.301 + you inform other peers where the object code and Corresponding
1.302 + Source of the work are being offered to the general public at no
1.303 + charge under subsection 6d.
1.304 + \end{enumerate}
1.305 +
1.306 +A separable portion of the object code, whose source code is excluded
1.307 +from the Corresponding Source as a System Library, need not be
1.308 +included in conveying the object code work.
1.309 +
1.310 +A ``User Product'' is either (1) a ``consumer product'', which means any
1.311 +tangible personal property which is normally used for personal, family,
1.312 +or household purposes, or (2) anything designed or sold for incorporation
1.313 +into a dwelling. In determining whether a product is a consumer product,
1.314 +doubtful cases shall be resolved in favor of coverage. For a particular
1.315 +product received by a particular user, ``normally used'' refers to a
1.316 +typical or common use of that class of product, regardless of the status
1.317 +of the particular user or of the way in which the particular user
1.318 +actually uses, or expects or is expected to use, the product. A product
1.319 +is a consumer product regardless of whether the product has substantial
1.320 +commercial, industrial or non-consumer uses, unless such uses represent
1.321 +the only significant mode of use of the product.
1.322 +
1.323 +``Installation Information'' for a User Product means any methods,
1.324 +procedures, authorization keys, or other information required to install
1.325 +and execute modified versions of a covered work in that User Product from
1.326 +a modified version of its Corresponding Source. The information must
1.327 +suffice to ensure that the continued functioning of the modified object
1.328 +code is in no case prevented or interfered with solely because
1.329 +modification has been made.
1.330 +
1.331 +If you convey an object code work under this section in, or with, or
1.332 +specifically for use in, a User Product, and the conveying occurs as
1.333 +part of a transaction in which the right of possession and use of the
1.334 +User Product is transferred to the recipient in perpetuity or for a
1.335 +fixed term (regardless of how the transaction is characterized), the
1.336 +Corresponding Source conveyed under this section must be accompanied
1.337 +by the Installation Information. But this requirement does not apply
1.338 +if neither you nor any third party retains the ability to install
1.339 +modified object code on the User Product (for example, the work has
1.340 +been installed in ROM).
1.341 +
1.342 +The requirement to provide Installation Information does not include a
1.343 +requirement to continue to provide support service, warranty, or updates
1.344 +for a work that has been modified or installed by the recipient, or for
1.345 +the User Product in which it has been modified or installed. Access to a
1.346 +network may be denied when the modification itself materially and
1.347 +adversely affects the operation of the network or violates the rules and
1.348 +protocols for communication across the network.
1.349 +
1.350 +Corresponding Source conveyed, and Installation Information provided,
1.351 +in accord with this section must be in a format that is publicly
1.352 +documented (and with an implementation available to the public in
1.353 +source code form), and must require no special password or key for
1.354 +unpacking, reading or copying.
1.355 +
1.356 +\item Additional Terms.
1.357 +
1.358 +``Additional permissions'' are terms that supplement the terms of this
1.359 +License by making exceptions from one or more of its conditions.
1.360 +Additional permissions that are applicable to the entire Program shall
1.361 +be treated as though they were included in this License, to the extent
1.362 +that they are valid under applicable law. If additional permissions
1.363 +apply only to part of the Program, that part may be used separately
1.364 +under those permissions, but the entire Program remains governed by
1.365 +this License without regard to the additional permissions.
1.366 +
1.367 +When you convey a copy of a covered work, you may at your option
1.368 +remove any additional permissions from that copy, or from any part of
1.369 +it. (Additional permissions may be written to require their own
1.370 +removal in certain cases when you modify the work.) You may place
1.371 +additional permissions on material, added by you to a covered work,
1.372 +for which you have or can give appropriate copyright permission.
1.373 +
1.374 +Notwithstanding any other provision of this License, for material you
1.375 +add to a covered work, you may (if authorized by the copyright holders of
1.376 +that material) supplement the terms of this License with terms:
1.377 + \begin{enumerate}
1.378 + \item Disclaiming warranty or limiting liability differently from the
1.379 + terms of sections 15 and 16 of this License; or
1.380 +
1.381 + \item Requiring preservation of specified reasonable legal notices or
1.382 + author attributions in that material or in the Appropriate Legal
1.383 + Notices displayed by works containing it; or
1.384 +
1.385 + \item Prohibiting misrepresentation of the origin of that material, or
1.386 + requiring that modified versions of such material be marked in
1.387 + reasonable ways as different from the original version; or
1.388 +
1.389 + \item Limiting the use for publicity purposes of names of licensors or
1.390 + authors of the material; or
1.391 +
1.392 + \item Declining to grant rights under trademark law for use of some
1.393 + trade names, trademarks, or service marks; or
1.394 +
1.395 + \item Requiring indemnification of licensors and authors of that
1.396 + material by anyone who conveys the material (or modified versions of
1.397 + it) with contractual assumptions of liability to the recipient, for
1.398 + any liability that these contractual assumptions directly impose on
1.399 + those licensors and authors.
1.400 + \end{enumerate}
1.401 +
1.402 +All other non-permissive additional terms are considered ``further
1.403 +restrictions'' within the meaning of section 10. If the Program as you
1.404 +received it, or any part of it, contains a notice stating that it is
1.405 +governed by this License along with a term that is a further
1.406 +restriction, you may remove that term. If a license document contains
1.407 +a further restriction but permits relicensing or conveying under this
1.408 +License, you may add to a covered work material governed by the terms
1.409 +of that license document, provided that the further restriction does
1.410 +not survive such relicensing or conveying.
1.411 +
1.412 +If you add terms to a covered work in accord with this section, you
1.413 +must place, in the relevant source files, a statement of the
1.414 +additional terms that apply to those files, or a notice indicating
1.415 +where to find the applicable terms.
1.416 +
1.417 +Additional terms, permissive or non-permissive, may be stated in the
1.418 +form of a separately written license, or stated as exceptions;
1.419 +the above requirements apply either way.
1.420 +
1.421 +\item Termination.
1.422 +
1.423 +You may not propagate or modify a covered work except as expressly
1.424 +provided under this License. Any attempt otherwise to propagate or
1.425 +modify it is void, and will automatically terminate your rights under
1.426 +this License (including any patent licenses granted under the third
1.427 +paragraph of section 11).
1.428 +
1.429 +However, if you cease all violation of this License, then your
1.430 +license from a particular copyright holder is reinstated (a)
1.431 +provisionally, unless and until the copyright holder explicitly and
1.432 +finally terminates your license, and (b) permanently, if the copyright
1.433 +holder fails to notify you of the violation by some reasonable means
1.434 +prior to 60 days after the cessation.
1.435 +
1.436 +Moreover, your license from a particular copyright holder is
1.437 +reinstated permanently if the copyright holder notifies you of the
1.438 +violation by some reasonable means, this is the first time you have
1.439 +received notice of violation of this License (for any work) from that
1.440 +copyright holder, and you cure the violation prior to 30 days after
1.441 +your receipt of the notice.
1.442 +
1.443 +Termination of your rights under this section does not terminate the
1.444 +licenses of parties who have received copies or rights from you under
1.445 +this License. If your rights have been terminated and not permanently
1.446 +reinstated, you do not qualify to receive new licenses for the same
1.447 +material under section 10.
1.448 +
1.449 +\item Acceptance Not Required for Having Copies.
1.450 +
1.451 +You are not required to accept this License in order to receive or
1.452 +run a copy of the Program. Ancillary propagation of a covered work
1.453 +occurring solely as a consequence of using peer-to-peer transmission
1.454 +to receive a copy likewise does not require acceptance. However,
1.455 +nothing other than this License grants you permission to propagate or
1.456 +modify any covered work. These actions infringe copyright if you do
1.457 +not accept this License. Therefore, by modifying or propagating a
1.458 +covered work, you indicate your acceptance of this License to do so.
1.459 +
1.460 +\item Automatic Licensing of Downstream Recipients.
1.461 +
1.462 +Each time you convey a covered work, the recipient automatically
1.463 +receives a license from the original licensors, to run, modify and
1.464 +propagate that work, subject to this License. You are not responsible
1.465 +for enforcing compliance by third parties with this License.
1.466 +
1.467 +An ``entity transaction'' is a transaction transferring control of an
1.468 +organization, or substantially all assets of one, or subdividing an
1.469 +organization, or merging organizations. If propagation of a covered
1.470 +work results from an entity transaction, each party to that
1.471 +transaction who receives a copy of the work also receives whatever
1.472 +licenses to the work the party's predecessor in interest had or could
1.473 +give under the previous paragraph, plus a right to possession of the
1.474 +Corresponding Source of the work from the predecessor in interest, if
1.475 +the predecessor has it or can get it with reasonable efforts.
1.476 +
1.477 +You may not impose any further restrictions on the exercise of the
1.478 +rights granted or affirmed under this License. For example, you may
1.479 +not impose a license fee, royalty, or other charge for exercise of
1.480 +rights granted under this License, and you may not initiate litigation
1.481 +(including a cross-claim or counterclaim in a lawsuit) alleging that
1.482 +any patent claim is infringed by making, using, selling, offering for
1.483 +sale, or importing the Program or any portion of it.
1.484 +
1.485 +\item Patents.
1.486 +
1.487 +A ``contributor'' is a copyright holder who authorizes use under this
1.488 +License of the Program or a work on which the Program is based. The
1.489 +work thus licensed is called the contributor's ``contributor version''.
1.490 +
1.491 +A contributor's ``essential patent claims'' are all patent claims
1.492 +owned or controlled by the contributor, whether already acquired or
1.493 +hereafter acquired, that would be infringed by some manner, permitted
1.494 +by this License, of making, using, or selling its contributor version,
1.495 +but do not include claims that would be infringed only as a
1.496 +consequence of further modification of the contributor version. For
1.497 +purposes of this definition, ``control'' includes the right to grant
1.498 +patent sublicenses in a manner consistent with the requirements of
1.499 +this License.
1.500 +
1.501 +Each contributor grants you a non-exclusive, worldwide, royalty-free
1.502 +patent license under the contributor's essential patent claims, to
1.503 +make, use, sell, offer for sale, import and otherwise run, modify and
1.504 +propagate the contents of its contributor version.
1.505 +
1.506 +In the following three paragraphs, a ``patent license'' is any express
1.507 +agreement or commitment, however denominated, not to enforce a patent
1.508 +(such as an express permission to practice a patent or covenant not to
1.509 +sue for patent infringement). To ``grant'' such a patent license to a
1.510 +party means to make such an agreement or commitment not to enforce a
1.511 +patent against the party.
1.512 +
1.513 +If you convey a covered work, knowingly relying on a patent license,
1.514 +and the Corresponding Source of the work is not available for anyone
1.515 +to copy, free of charge and under the terms of this License, through a
1.516 +publicly available network server or other readily accessible means,
1.517 +then you must either (1) cause the Corresponding Source to be so
1.518 +available, or (2) arrange to deprive yourself of the benefit of the
1.519 +patent license for this particular work, or (3) arrange, in a manner
1.520 +consistent with the requirements of this License, to extend the patent
1.521 +license to downstream recipients. ``Knowingly relying'' means you have
1.522 +actual knowledge that, but for the patent license, your conveying the
1.523 +covered work in a country, or your recipient's use of the covered work
1.524 +in a country, would infringe one or more identifiable patents in that
1.525 +country that you have reason to believe are valid.
1.526 +
1.527 +If, pursuant to or in connection with a single transaction or
1.528 +arrangement, you convey, or propagate by procuring conveyance of, a
1.529 +covered work, and grant a patent license to some of the parties
1.530 +receiving the covered work authorizing them to use, propagate, modify
1.531 +or convey a specific copy of the covered work, then the patent license
1.532 +you grant is automatically extended to all recipients of the covered
1.533 +work and works based on it.
1.534 +
1.535 +A patent license is ``discriminatory'' if it does not include within
1.536 +the scope of its coverage, prohibits the exercise of, or is
1.537 +conditioned on the non-exercise of one or more of the rights that are
1.538 +specifically granted under this License. You may not convey a covered
1.539 +work if you are a party to an arrangement with a third party that is
1.540 +in the business of distributing software, under which you make payment
1.541 +to the third party based on the extent of your activity of conveying
1.542 +the work, and under which the third party grants, to any of the
1.543 +parties who would receive the covered work from you, a discriminatory
1.544 +patent license (a) in connection with copies of the covered work
1.545 +conveyed by you (or copies made from those copies), or (b) primarily
1.546 +for and in connection with specific products or compilations that
1.547 +contain the covered work, unless you entered into that arrangement,
1.548 +or that patent license was granted, prior to 28 March 2007.
1.549 +
1.550 +Nothing in this License shall be construed as excluding or limiting
1.551 +any implied license or other defenses to infringement that may
1.552 +otherwise be available to you under applicable patent law.
1.553 +
1.554 +\item No Surrender of Others' Freedom.
1.555 +
1.556 +If conditions are imposed on you (whether by court order, agreement or
1.557 +otherwise) that contradict the conditions of this License, they do not
1.558 +excuse you from the conditions of this License. If you cannot convey a
1.559 +covered work so as to satisfy simultaneously your obligations under this
1.560 +License and any other pertinent obligations, then as a consequence you may
1.561 +not convey it at all. For example, if you agree to terms that obligate you
1.562 +to collect a royalty for further conveying from those to whom you convey
1.563 +the Program, the only way you could satisfy both those terms and this
1.564 +License would be to refrain entirely from conveying the Program.
1.565 +
1.566 +\item Remote Network Interaction; Use with the GNU General Public License.
1.567 +
1.568 +Notwithstanding any other provision of this License, if you modify the
1.569 +Program, your modified version must prominently offer all users interacting
1.570 +with it remotely through a computer network (if your version supports such
1.571 +interaction) an opportunity to receive the Corresponding Source of your
1.572 +version by providing access to the Corresponding Source from a network
1.573 +server at no charge, through some standard or customary means of
1.574 +facilitating copying of software. This Corresponding Source shall include
1.575 +the Corresponding Source for any work covered by version 3 of the GNU
1.576 +General Public License that is incorporated pursuant to the following
1.577 +paragraph.
1.578 +
1.579 +Notwithstanding any other provision of this License, you have permission to
1.580 +link or combine any covered work with a work licensed under version 3 of
1.581 +the GNU General Public License into a single combined work, and to convey
1.582 +the resulting work. The terms of this License will continue to apply to
1.583 +the part which is the covered work, but the work with which it is combined
1.584 +will remain governed by version 3 of the GNU General Public License.
1.585 +
1.586 +\item Revised Versions of this License.
1.587 +
1.588 +The Free Software Foundation may publish revised and/or new versions of
1.589 +the GNU Affero General Public License from time to time. Such new versions will
1.590 +be similar in spirit to the present version, but may differ in detail to
1.591 +address new problems or concerns.
1.592 +
1.593 +Each version is given a distinguishing version number. If the
1.594 +Program specifies that a certain numbered version of the GNU Affero General
1.595 +Public License ``or any later version'' applies to it, you have the
1.596 +option of following the terms and conditions either of that numbered
1.597 +version or of any later version published by the Free Software
1.598 +Foundation. If the Program does not specify a version number of the
1.599 +GNU Affero General Public License, you may choose any version ever published
1.600 +by the Free Software Foundation.
1.601 +
1.602 +If the Program specifies that a proxy can decide which future
1.603 +versions of the GNU Affero General Public License can be used, that proxy's
1.604 +public statement of acceptance of a version permanently authorizes you
1.605 +to choose that version for the Program.
1.606 +
1.607 +Later license versions may give you additional or different
1.608 +permissions. However, no additional obligations are imposed on any
1.609 +author or copyright holder as a result of your choosing to follow a
1.610 +later version.
1.611 +
1.612 +\item Disclaimer of Warranty.
1.613 +
1.614 +\begin{sloppypar}
1.615 + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
1.616 + APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
1.617 + COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS''
1.618 + WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
1.619 + INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
1.620 + MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE
1.621 + RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
1.622 + SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
1.623 + NECESSARY SERVICING, REPAIR OR CORRECTION.
1.624 +\end{sloppypar}
1.625 +
1.626 +\item Limitation of Liability.
1.627 +
1.628 + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
1.629 + WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
1.630 + AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
1.631 + DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
1.632 + DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
1.633 + (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
1.634 + INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE
1.635 + OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
1.636 + HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
1.637 + DAMAGES.
1.638 +
1.639 +\item Interpretation of Sections 15 and 16.
1.640 +
1.641 +If the disclaimer of warranty and limitation of liability provided
1.642 +above cannot be given local legal effect according to their terms,
1.643 +reviewing courts shall apply local law that most closely approximates
1.644 +an absolute waiver of all civil liability in connection with the
1.645 +Program, unless a warranty or assumption of liability accompanies a
1.646 +copy of the Program in return for a fee.

1.652 +How to Apply These Terms to Your New Programs
1.653 +\end{center}
1.654 +
1.655 +If you develop a new program, and you want it to be of the greatest
1.656 +possible use to the public, the best way to achieve this is to make it
1.657 +free software which everyone can redistribute and change under these terms.
1.658 +
1.659 +To do so, attach the following notices to the program. It is safest
1.660 +to attach them to the start of each source file to most effectively
1.661 +state the exclusion of warranty; and each file should have at least
1.662 +the ``copyright'' line and a pointer to where the full notice is found.
1.663 +
1.664 +{\footnotesize

1.669 +
1.670 +This program is free software: you can redistribute it and/or modify
1.671 +it under the terms of the GNU Affero General Public License as published by
1.672 +the Free Software Foundation, either version 3 of the License, or
1.673 +(at your option) any later version.
1.674 +
1.675 +This program is distributed in the hope that it will be useful,
1.676 +but WITHOUT ANY WARRANTY; without even the implied warranty of
1.677 +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
1.678 +GNU Affero General Public License for more details.
1.679 +
1.680 +You should have received a copy of the GNU Affero General Public License
1.681 +along with this program. If not, see <http://www.gnu.org/licenses/>.
1.682 +\end{verbatim}
1.683 +}
1.684 +
1.685 +Also add information on how to contact you by electronic and paper mail.
1.686 +
1.687 +If your software can interact with users remotely through a computer
1.688 +network, you should also make sure that it provides a way for users to
1.689 +get its source. For example, if your program is a web application, its
1.690 +interface could display a ``Source'' link that leads users to an archive
1.691 +of the code. There are many ways you could offer source, and different
1.692 +solutions will be better for different programs; see section 13 for the
1.693 +specific requirements.
1.694 +
1.695 +You should also get your employer (if you work as a programmer) or
1.696 +school, if any, to sign a ``copyright disclaimer'' for the program, if
1.697 +necessary. For more information on this, and how to apply and follow
1.698 +the GNU AGPL, see \texttt{http://www.gnu.org/licenses/}.
