2.25 +\begin{abstract}
2.26 +The GNU Affero General Public License is a free, copyleft license
2.27 +for software and other kinds of works, specifically designed to ensure
2.28 +cooperation with the community in the case of network server software.
2.29 +
2.30 +The licenses for most software and other practical works are
2.31 +designed to take away your freedom to share and change the works. By
2.32 +contrast, our General Public Licenses are intended to guarantee your
2.33 +freedom to share and change all versions of a program--to make sure it
2.34 +remains free software for all its users.
2.35 +
2.36 +When we speak of free software, we are referring to freedom, not
2.37 +price. Our General Public Licenses are designed to make sure that you
2.38 +have the freedom to distribute copies of free software (and charge for
2.39 +them if you wish), that you receive source code or can get it if you
2.40 +want it, that you can change the software or use pieces of it in new
2.41 +free programs, and that you know you can do these things.
2.42 +
2.43 +Developers that use our General Public Licenses protect your rights
2.44 +with two steps: (1) assert copyright on the software, and (2) offer
2.45 +you this License which gives you legal permission to copy, distribute
2.46 +and/or modify the software.
2.47 +
2.48 +A secondary benefit of defending all users' freedom is that
2.49 +improvements made in alternate versions of the program, if they
2.50 +receive widespread use, become available for other developers to
2.51 +incorporate. Many developers of free software are heartened and
2.52 +encouraged by the resulting cooperation. However, in the case of
2.53 +software used on network servers, this result may fail to come about.
2.54 +The GNU General Public License permits making a modified version and
2.55 +letting the public access it on a server without ever releasing its
2.56 +source code to the public.
2.57 +
2.58 +The GNU Affero General Public License is designed specifically to
2.59 +ensure that, in such cases, the modified source code becomes available
2.60 +to the community. It requires the operator of a network server to
2.61 +provide the source code of the modified version running there to the
2.62 +users of that server. Therefore, public use of a modified version, on
2.63 +a publicly accessible server, gives the public access to the source
2.64 +code of the modified version.
2.65 +
2.66 +An older license, called the Affero General Public License and
2.67 +published by Affero, was designed to accomplish similar goals. This is
2.68 +a different license, not a version of the Affero GPL, but Affero has
2.69 +released a new version of the Affero GPL which permits relicensing under
2.70 +this license.
2.71 +
2.72 +The precise terms and conditions for copying, distribution and
2.73 +modification follow.

2.77 +{\Large \sc Terms and Conditions}
2.78 +\end{center}
2.79 +
2.80 +
2.81 +\begin{enumerate}
2.82 +
2.83 +\addtocounter{enumi}{-1}
2.84 +
2.85 +\item Definitions.
2.86 +
2.87 +``This License'' refers to version 3 of the GNU Affero General Public License.
2.88 +
2.89 +``Copyright'' also means copyright-like laws that apply to other kinds of
2.90 +works, such as semiconductor masks.
2.91 +
2.92 +``The Program'' refers to any copyrightable work licensed under this
2.93 +License. Each licensee is addressed as ``you''. ``Licensees'' and
2.94 +``recipients'' may be individuals or organizations.
2.95 +
2.96 +To ``modify'' a work means to copy from or adapt all or part of the work
2.97 +in a fashion requiring copyright permission, other than the making of an
2.98 +exact copy. The resulting work is called a ``modified version'' of the
2.99 +earlier work or a work ``based on'' the earlier work.
2.100 +
2.101 +A ``covered work'' means either the unmodified Program or a work based
2.102 +on the Program.
2.103 +
2.104 +To ``propagate'' a work means to do anything with it that, without
2.105 +permission, would make you directly or secondarily liable for
2.106 +infringement under applicable copyright law, except executing it on a
2.107 +computer or modifying a private copy. Propagation includes copying,
2.108 +distribution (with or without modification), making available to the
2.109 +public, and in some countries other activities as well.
2.110 +
2.111 +To ``convey'' a work means any kind of propagation that enables other
2.112 +parties to make or receive copies. Mere interaction with a user through
2.113 +a computer network, with no transfer of a copy, is not conveying.
2.114 +
2.115 +An interactive user interface displays ``Appropriate Legal Notices''
2.116 +to the extent that it includes a convenient and prominently visible
2.117 +feature that (1) displays an appropriate copyright notice, and (2)
2.118 +tells the user that there is no warranty for the work (except to the
2.119 +extent that warranties are provided), that licensees may convey the
2.120 +work under this License, and how to view a copy of this License. If
2.121 +the interface presents a list of user commands or options, such as a
2.122 +menu, a prominent item in the list meets this criterion.
2.123 +
2.124 +\item Source Code.
2.125 +
2.126 +The ``source code'' for a work means the preferred form of the work
2.127 +for making modifications to it. ``Object code'' means any non-source
2.128 +form of a work.
2.129 +
2.130 +A ``Standard Interface'' means an interface that either is an official
2.131 +standard defined by a recognized standards body, or, in the case of
2.132 +interfaces specified for a particular programming language, one that
2.133 +is widely used among developers working in that language.
2.134 +
2.135 +The ``System Libraries'' of an executable work include anything, other
2.136 +than the work as a whole, that (a) is included in the normal form of
2.137 +packaging a Major Component, but which is not part of that Major
2.138 +Component, and (b) serves only to enable use of the work with that
2.139 +Major Component, or to implement a Standard Interface for which an
2.140 +implementation is available to the public in source code form. A
2.141 +``Major Component'', in this context, means a major essential component
2.142 +(kernel, window system, and so on) of the specific operating system
2.143 +(if any) on which the executable work runs, or a compiler used to
2.144 +produce the work, or an object code interpreter used to run it.
2.145 +
2.146 +The ``Corresponding Source'' for a work in object code form means all
2.147 +the source code needed to generate, install, and (for an executable
2.148 +work) run the object code and to modify the work, including scripts to
2.149 +control those activities. However, it does not include the work's
2.150 +System Libraries, or general-purpose tools or generally available free
2.151 +programs which are used unmodified in performing those activities but
2.152 +which are not part of the work. For example, Corresponding Source
2.153 +includes interface definition files associated with source files for
2.154 +the work, and the source code for shared libraries and dynamically
2.155 +linked subprograms that the work is specifically designed to require,
2.156 +such as by intimate data communication or control flow between those
2.157 +subprograms and other parts of the work.
2.158 +
2.159 +The Corresponding Source need not include anything that users
2.160 +can regenerate automatically from other parts of the Corresponding
2.161 +Source.
2.162 +
2.163 +The Corresponding Source for a work in source code form is that
2.164 +same work.
2.165 +
2.166 +\item Basic Permissions.
2.167 +
2.168 +All rights granted under this License are granted for the term of
2.169 +copyright on the Program, and are irrevocable provided the stated
2.170 +conditions are met. This License explicitly affirms your unlimited
2.171 +permission to run the unmodified Program. The output from running a
2.172 +covered work is covered by this License only if the output, given its
2.173 +content, constitutes a covered work. This License acknowledges your
2.174 +rights of fair use or other equivalent, as provided by copyright law.
2.175 +
2.176 +You may make, run and propagate covered works that you do not
2.177 +convey, without conditions so long as your license otherwise remains
2.178 +in force. You may convey covered works to others for the sole purpose
2.179 +of having them make modifications exclusively for you, or provide you
2.180 +with facilities for running those works, provided that you comply with
2.181 +the terms of this License in conveying all material for which you do
2.182 +not control copyright. Those thus making or running the covered works
2.183 +for you must do so exclusively on your behalf, under your direction
2.184 +and control, on terms that prohibit them from making any copies of
2.185 +your copyrighted material outside their relationship with you.
2.186 +
2.187 +Conveying under any other circumstances is permitted solely under
2.188 +the conditions stated below. Sublicensing is not allowed; section 10
2.189 +makes it unnecessary.
2.190 +
2.191 +\item Protecting Users' Legal Rights From Anti-Circumvention Law.
2.192 +
2.193 +No covered work shall be deemed part of an effective technological
2.194 +measure under any applicable law fulfilling obligations under article
2.195 +11 of the WIPO copyright treaty adopted on 20 December 1996, or
2.196 +similar laws prohibiting or restricting circumvention of such
2.197 +measures.
2.198 +
2.199 +When you convey a covered work, you waive any legal power to forbid
2.200 +circumvention of technological measures to the extent such circumvention
2.201 +is effected by exercising rights under this License with respect to
2.202 +the covered work, and you disclaim any intention to limit operation or
2.203 +modification of the work as a means of enforcing, against the work's
2.204 +users, your or third parties' legal rights to forbid circumvention of
2.205 +technological measures.
2.206 +
2.207 +\item Conveying Verbatim Copies.
2.208 +
2.209 +You may convey verbatim copies of the Program's source code as you
2.210 +receive it, in any medium, provided that you conspicuously and
2.211 +appropriately publish on each copy an appropriate copyright notice;
2.212 +keep intact all notices stating that this License and any
2.213 +non-permissive terms added in accord with section 7 apply to the code;
2.214 +keep intact all notices of the absence of any warranty; and give all
2.215 +recipients a copy of this License along with the Program.
2.216 +
2.217 +You may charge any price or no price for each copy that you convey,
2.218 +and you may offer support or warranty protection for a fee.
2.219 +
2.220 +\item Conveying Modified Source Versions.
2.221 +
2.222 +You may convey a work based on the Program, or the modifications to
2.223 +produce it from the Program, in the form of source code under the
2.224 +terms of section 4, provided that you also meet all of these conditions:
2.225 + \begin{enumerate}
2.226 + \item The work must carry prominent notices stating that you modified
2.227 + it, and giving a relevant date.
2.228 +
2.229 + \item The work must carry prominent notices stating that it is
2.230 + released under this License and any conditions added under section
2.231 + 7. This requirement modifies the requirement in section 4 to
2.232 + ``keep intact all notices''.
2.233 +
2.234 + \item You must license the entire work, as a whole, under this
2.235 + License to anyone who comes into possession of a copy. This
2.236 + License will therefore apply, along with any applicable section 7
2.237 + additional terms, to the whole of the work, and all its parts,
2.238 + regardless of how they are packaged. This License gives no
2.239 + permission to license the work in any other way, but it does not
2.240 + invalidate such permission if you have separately received it.
2.241 +
2.242 + \item If the work has interactive user interfaces, each must display
2.243 + Appropriate Legal Notices; however, if the Program has interactive
2.244 + interfaces that do not display Appropriate Legal Notices, your
2.245 + work need not make them do so.
2.246 +\end{enumerate}
2.247 +A compilation of a covered work with other separate and independent
2.248 +works, which are not by their nature extensions of the covered work,
2.249 +and which are not combined with it such as to form a larger program,
2.250 +in or on a volume of a storage or distribution medium, is called an
2.251 +``aggregate'' if the compilation and its resulting copyright are not
2.252 +used to limit the access or legal rights of the compilation's users
2.253 +beyond what the individual works permit. Inclusion of a covered work
2.254 +in an aggregate does not cause this License to apply to the other
2.255 +parts of the aggregate.
2.256 +
2.257 +\item Conveying Non-Source Forms.
2.258 +
2.259 +You may convey a covered work in object code form under the terms
2.260 +of sections 4 and 5, provided that you also convey the
2.261 +machine-readable Corresponding Source under the terms of this License,
2.262 +in one of these ways:
2.263 + \begin{enumerate}
2.264 + \item Convey the object code in, or embodied in, a physical product
2.265 + (including a physical distribution medium), accompanied by the
2.266 + Corresponding Source fixed on a durable physical medium
2.267 + customarily used for software interchange.
2.268 +
2.269 + \item Convey the object code in, or embodied in, a physical product
2.270 + (including a physical distribution medium), accompanied by a
2.271 + written offer, valid for at least three years and valid for as
2.272 + long as you offer spare parts or customer support for that product
2.273 + model, to give anyone who possesses the object code either (1) a
2.274 + copy of the Corresponding Source for all the software in the
2.275 + product that is covered by this License, on a durable physical
2.276 + medium customarily used for software interchange, for a price no
2.277 + more than your reasonable cost of physically performing this
2.278 + conveying of source, or (2) access to copy the
2.279 + Corresponding Source from a network server at no charge.
2.280 +
2.281 + \item Convey individual copies of the object code with a copy of the
2.282 + written offer to provide the Corresponding Source. This
2.283 + alternative is allowed only occasionally and noncommercially, and
2.284 + only if you received the object code with such an offer, in accord
2.285 + with subsection 6b.
2.286 +
2.287 + \item Convey the object code by offering access from a designated
2.288 + place (gratis or for a charge), and offer equivalent access to the
2.289 + Corresponding Source in the same way through the same place at no
2.290 + further charge. You need not require recipients to copy the
2.291 + Corresponding Source along with the object code. If the place to
2.292 + copy the object code is a network server, the Corresponding Source
2.293 + may be on a different server (operated by you or a third party)
2.294 + that supports equivalent copying facilities, provided you maintain
2.295 + clear directions next to the object code saying where to find the
2.296 + Corresponding Source. Regardless of what server hosts the
2.297 + Corresponding Source, you remain obligated to ensure that it is
2.298 + available for as long as needed to satisfy these requirements.
2.299 +
2.300 + \item Convey the object code using peer-to-peer transmission, provided
2.301 + you inform other peers where the object code and Corresponding
2.302 + Source of the work are being offered to the general public at no
2.303 + charge under subsection 6d.
2.304 + \end{enumerate}
2.305 +
2.306 +A separable portion of the object code, whose source code is excluded
2.307 +from the Corresponding Source as a System Library, need not be
2.308 +included in conveying the object code work.
2.309 +
2.310 +A ``User Product'' is either (1) a ``consumer product'', which means any
2.311 +tangible personal property which is normally used for personal, family,
2.312 +or household purposes, or (2) anything designed or sold for incorporation
2.313 +into a dwelling. In determining whether a product is a consumer product,
2.314 +doubtful cases shall be resolved in favor of coverage. For a particular
2.315 +product received by a particular user, ``normally used'' refers to a
2.316 +typical or common use of that class of product, regardless of the status
2.317 +of the particular user or of the way in which the particular user
2.318 +actually uses, or expects or is expected to use, the product. A product
2.319 +is a consumer product regardless of whether the product has substantial
2.320 +commercial, industrial or non-consumer uses, unless such uses represent
2.321 +the only significant mode of use of the product.
2.322 +
2.323 +``Installation Information'' for a User Product means any methods,
2.324 +procedures, authorization keys, or other information required to install
2.325 +and execute modified versions of a covered work in that User Product from
2.326 +a modified version of its Corresponding Source. The information must
2.327 +suffice to ensure that the continued functioning of the modified object
2.328 +code is in no case prevented or interfered with solely because
2.329 +modification has been made.
2.330 +
2.331 +If you convey an object code work under this section in, or with, or
2.332 +specifically for use in, a User Product, and the conveying occurs as
2.333 +part of a transaction in which the right of possession and use of the
2.334 +User Product is transferred to the recipient in perpetuity or for a
2.335 +fixed term (regardless of how the transaction is characterized), the
2.336 +Corresponding Source conveyed under this section must be accompanied
2.337 +by the Installation Information. But this requirement does not apply
2.338 +if neither you nor any third party retains the ability to install
2.339 +modified object code on the User Product (for example, the work has
2.340 +been installed in ROM).
2.341 +
2.342 +The requirement to provide Installation Information does not include a
2.343 +requirement to continue to provide support service, warranty, or updates
2.344 +for a work that has been modified or installed by the recipient, or for
2.345 +the User Product in which it has been modified or installed. Access to a
2.346 +network may be denied when the modification itself materially and
2.347 +adversely affects the operation of the network or violates the rules and
2.348 +protocols for communication across the network.
2.349 +
2.350 +Corresponding Source conveyed, and Installation Information provided,
2.351 +in accord with this section must be in a format that is publicly
2.352 +documented (and with an implementation available to the public in
2.353 +source code form), and must require no special password or key for
2.354 +unpacking, reading or copying.
2.355 +
2.356 +\item Additional Terms.
2.357 +
2.358 +``Additional permissions'' are terms that supplement the terms of this
2.359 +License by making exceptions from one or more of its conditions.
2.360 +Additional permissions that are applicable to the entire Program shall
2.361 +be treated as though they were included in this License, to the extent
2.362 +that they are valid under applicable law. If additional permissions
2.363 +apply only to part of the Program, that part may be used separately
2.364 +under those permissions, but the entire Program remains governed by
2.365 +this License without regard to the additional permissions.
2.366 +
2.367 +When you convey a copy of a covered work, you may at your option
2.368 +remove any additional permissions from that copy, or from any part of
2.369 +it. (Additional permissions may be written to require their own
2.370 +removal in certain cases when you modify the work.) You may place
2.371 +additional permissions on material, added by you to a covered work,
2.372 +for which you have or can give appropriate copyright permission.
2.373 +
2.374 +Notwithstanding any other provision of this License, for material you
2.375 +add to a covered work, you may (if authorized by the copyright holders of
2.376 +that material) supplement the terms of this License with terms:
2.377 + \begin{enumerate}
2.378 + \item Disclaiming warranty or limiting liability differently from the
2.379 + terms of sections 15 and 16 of this License; or
2.380 +
2.381 + \item Requiring preservation of specified reasonable legal notices or
2.382 + author attributions in that material or in the Appropriate Legal
2.383 + Notices displayed by works containing it; or
2.384 +
2.385 + \item Prohibiting misrepresentation of the origin of that material, or
2.386 + requiring that modified versions of such material be marked in
2.387 + reasonable ways as different from the original version; or
2.388 +
2.389 + \item Limiting the use for publicity purposes of names of licensors or
2.390 + authors of the material; or
2.391 +
2.392 + \item Declining to grant rights under trademark law for use of some
2.393 + trade names, trademarks, or service marks; or
2.394 +
2.395 + \item Requiring indemnification of licensors and authors of that
2.396 + material by anyone who conveys the material (or modified versions of
2.397 + it) with contractual assumptions of liability to the recipient, for
2.398 + any liability that these contractual assumptions directly impose on
2.399 + those licensors and authors.
2.400 + \end{enumerate}
2.401 +
2.402 +All other non-permissive additional terms are considered ``further
2.403 +restrictions'' within the meaning of section 10. If the Program as you
2.404 +received it, or any part of it, contains a notice stating that it is
2.405 +governed by this License along with a term that is a further
2.406 +restriction, you may remove that term. If a license document contains
2.407 +a further restriction but permits relicensing or conveying under this
2.408 +License, you may add to a covered work material governed by the terms
2.409 +of that license document, provided that the further restriction does
2.410 +not survive such relicensing or conveying.
2.411 +
2.412 +If you add terms to a covered work in accord with this section, you
2.413 +must place, in the relevant source files, a statement of the
2.414 +additional terms that apply to those files, or a notice indicating
2.415 +where to find the applicable terms.
2.416 +
2.417 +Additional terms, permissive or non-permissive, may be stated in the
2.418 +form of a separately written license, or stated as exceptions;
2.419 +the above requirements apply either way.
2.420 +
2.421 +\item Termination.
2.422 +
2.423 +You may not propagate or modify a covered work except as expressly
2.424 +provided under this License. Any attempt otherwise to propagate or
2.425 +modify it is void, and will automatically terminate your rights under
2.426 +this License (including any patent licenses granted under the third
2.427 +paragraph of section 11).
2.428 +
2.429 +However, if you cease all violation of this License, then your
2.430 +license from a particular copyright holder is reinstated (a)
2.431 +provisionally, unless and until the copyright holder explicitly and
2.432 +finally terminates your license, and (b) permanently, if the copyright
2.433 +holder fails to notify you of the violation by some reasonable means
2.434 +prior to 60 days after the cessation.
2.435 +
2.436 +Moreover, your license from a particular copyright holder is
2.437 +reinstated permanently if the copyright holder notifies you of the
2.438 +violation by some reasonable means, this is the first time you have
2.439 +received notice of violation of this License (for any work) from that
2.440 +copyright holder, and you cure the violation prior to 30 days after
2.441 +your receipt of the notice.
2.442 +
2.443 +Termination of your rights under this section does not terminate the
2.444 +licenses of parties who have received copies or rights from you under
2.445 +this License. If your rights have been terminated and not permanently
2.446 +reinstated, you do not qualify to receive new licenses for the same
2.447 +material under section 10.
2.448 +
2.449 +\item Acceptance Not Required for Having Copies.
2.450 +
2.451 +You are not required to accept this License in order to receive or
2.452 +run a copy of the Program. Ancillary propagation of a covered work
2.453 +occurring solely as a consequence of using peer-to-peer transmission
2.454 +to receive a copy likewise does not require acceptance. However,
2.455 +nothing other than this License grants you permission to propagate or
2.456 +modify any covered work. These actions infringe copyright if you do
2.457 +not accept this License. Therefore, by modifying or propagating a
2.458 +covered work, you indicate your acceptance of this License to do so.
2.459 +
2.460 +\item Automatic Licensing of Downstream Recipients.
2.461 +
2.462 +Each time you convey a covered work, the recipient automatically
2.463 +receives a license from the original licensors, to run, modify and
2.464 +propagate that work, subject to this License. You are not responsible
2.465 +for enforcing compliance by third parties with this License.
2.466 +
2.467 +An ``entity transaction'' is a transaction transferring control of an
2.468 +organization, or substantially all assets of one, or subdividing an
2.469 +organization, or merging organizations. If propagation of a covered
2.470 +work results from an entity transaction, each party to that
2.471 +transaction who receives a copy of the work also receives whatever
2.472 +licenses to the work the party's predecessor in interest had or could
2.473 +give under the previous paragraph, plus a right to possession of the
2.474 +Corresponding Source of the work from the predecessor in interest, if
2.475 +the predecessor has it or can get it with reasonable efforts.
2.476 +
2.477 +You may not impose any further restrictions on the exercise of the
2.478 +rights granted or affirmed under this License. For example, you may
2.479 +not impose a license fee, royalty, or other charge for exercise of
2.480 +rights granted under this License, and you may not initiate litigation
2.481 +(including a cross-claim or counterclaim in a lawsuit) alleging that
2.482 +any patent claim is infringed by making, using, selling, offering for
2.483 +sale, or importing the Program or any portion of it.
2.484 +
2.485 +\item Patents.
2.486 +
2.487 +A ``contributor'' is a copyright holder who authorizes use under this
2.488 +License of the Program or a work on which the Program is based. The
2.489 +work thus licensed is called the contributor's ``contributor version''.
2.490 +
2.491 +A contributor's ``essential patent claims'' are all patent claims
2.492 +owned or controlled by the contributor, whether already acquired or
2.493 +hereafter acquired, that would be infringed by some manner, permitted
2.494 +by this License, of making, using, or selling its contributor version,
2.495 +but do not include claims that would be infringed only as a
2.496 +consequence of further modification of the contributor version. For
2.497 +purposes of this definition, ``control'' includes the right to grant
2.498 +patent sublicenses in a manner consistent with the requirements of
2.499 +this License.
2.500 +
2.501 +Each contributor grants you a non-exclusive, worldwide, royalty-free
2.502 +patent license under the contributor's essential patent claims, to
2.503 +make, use, sell, offer for sale, import and otherwise run, modify and
2.504 +propagate the contents of its contributor version.
2.505 +
2.506 +In the following three paragraphs, a ``patent license'' is any express
2.507 +agreement or commitment, however denominated, not to enforce a patent
2.508 +(such as an express permission to practice a patent or covenant not to
2.509 +sue for patent infringement). To ``grant'' such a patent license to a
2.510 +party means to make such an agreement or commitment not to enforce a
2.511 +patent against the party.
2.512 +
2.513 +If you convey a covered work, knowingly relying on a patent license,
2.514 +and the Corresponding Source of the work is not available for anyone
2.515 +to copy, free of charge and under the terms of this License, through a
2.516 +publicly available network server or other readily accessible means,
2.517 +then you must either (1) cause the Corresponding Source to be so
2.518 +available, or (2) arrange to deprive yourself of the benefit of the
2.519 +patent license for this particular work, or (3) arrange, in a manner
2.520 +consistent with the requirements of this License, to extend the patent
2.521 +license to downstream recipients. ``Knowingly relying'' means you have
2.522 +actual knowledge that, but for the patent license, your conveying the
2.523 +covered work in a country, or your recipient's use of the covered work
2.524 +in a country, would infringe one or more identifiable patents in that
2.525 +country that you have reason to believe are valid.
2.526 +
2.527 +If, pursuant to or in connection with a single transaction or
2.528 +arrangement, you convey, or propagate by procuring conveyance of, a
2.529 +covered work, and grant a patent license to some of the parties
2.530 +receiving the covered work authorizing them to use, propagate, modify
2.531 +or convey a specific copy of the covered work, then the patent license
2.532 +you grant is automatically extended to all recipients of the covered
2.533 +work and works based on it.
2.534 +
2.535 +A patent license is ``discriminatory'' if it does not include within
2.536 +the scope of its coverage, prohibits the exercise of, or is
2.537 +conditioned on the non-exercise of one or more of the rights that are
2.538 +specifically granted under this License. You may not convey a covered
2.539 +work if you are a party to an arrangement with a third party that is
2.540 +in the business of distributing software, under which you make payment
2.541 +to the third party based on the extent of your activity of conveying
2.542 +the work, and under which the third party grants, to any of the
2.543 +parties who would receive the covered work from you, a discriminatory
2.544 +patent license (a) in connection with copies of the covered work
2.545 +conveyed by you (or copies made from those copies), or (b) primarily
2.546 +for and in connection with specific products or compilations that
2.547 +contain the covered work, unless you entered into that arrangement,
2.548 +or that patent license was granted, prior to 28 March 2007.
2.549 +
2.550 +Nothing in this License shall be construed as excluding or limiting
2.551 +any implied license or other defenses to infringement that may
2.552 +otherwise be available to you under applicable patent law.
2.553 +
2.554 +\item No Surrender of Others' Freedom.
2.555 +
2.556 +If conditions are imposed on you (whether by court order, agreement or
2.557 +otherwise) that contradict the conditions of this License, they do not
2.558 +excuse you from the conditions of this License. If you cannot convey a
2.559 +covered work so as to satisfy simultaneously your obligations under this
2.560 +License and any other pertinent obligations, then as a consequence you may
2.561 +not convey it at all. For example, if you agree to terms that obligate you
2.562 +to collect a royalty for further conveying from those to whom you convey
2.563 +the Program, the only way you could satisfy both those terms and this
2.564 +License would be to refrain entirely from conveying the Program.
2.565 +
2.566 +\item Remote Network Interaction; Use with the GNU General Public License.
2.567 +
2.568 +Notwithstanding any other provision of this License, if you modify the
2.569 +Program, your modified version must prominently offer all users interacting
2.570 +with it remotely through a computer network (if your version supports such
2.571 +interaction) an opportunity to receive the Corresponding Source of your
2.572 +version by providing access to the Corresponding Source from a network
2.573 +server at no charge, through some standard or customary means of
2.574 +facilitating copying of software. This Corresponding Source shall include
2.575 +the Corresponding Source for any work covered by version 3 of the GNU
2.576 +General Public License that is incorporated pursuant to the following
2.577 +paragraph.
2.578 +
2.579 +Notwithstanding any other provision of this License, you have permission to
2.580 +link or combine any covered work with a work licensed under version 3 of
2.581 +the GNU General Public License into a single combined work, and to convey
2.582 +the resulting work. The terms of this License will continue to apply to
2.583 +the part which is the covered work, but the work with which it is combined
2.584 +will remain governed by version 3 of the GNU General Public License.
2.585 +
2.586 +\item Revised Versions of this License.
2.587 +
2.588 +The Free Software Foundation may publish revised and/or new versions of
2.589 +the GNU Affero General Public License from time to time. Such new versions will
2.590 +be similar in spirit to the present version, but may differ in detail to
2.591 +address new problems or concerns.
2.592 +
2.593 +Each version is given a distinguishing version number. If the
2.594 +Program specifies that a certain numbered version of the GNU Affero General
2.595 +Public License ``or any later version'' applies to it, you have the
2.596 +option of following the terms and conditions either of that numbered
2.597 +version or of any later version published by the Free Software
2.598 +Foundation. If the Program does not specify a version number of the
2.599 +GNU Affero General Public License, you may choose any version ever published
2.600 +by the Free Software Foundation.
2.601 +
2.602 +If the Program specifies that a proxy can decide which future
2.603 +versions of the GNU Affero General Public License can be used, that proxy's
2.604 +public statement of acceptance of a version permanently authorizes you
2.605 +to choose that version for the Program.
2.606 +
2.607 +Later license versions may give you additional or different
2.608 +permissions. However, no additional obligations are imposed on any
2.609 +author or copyright holder as a result of your choosing to follow a
2.610 +later version.
2.611 +
2.612 +\item Disclaimer of Warranty.
2.613 +
2.614 +\begin{sloppypar}
2.615 + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
2.616 + APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE
2.617 + COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS''
2.618 + WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
2.619 + INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
2.620 + MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE
2.621 + RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.
2.622 + SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL
2.623 + NECESSARY SERVICING, REPAIR OR CORRECTION.
2.624 +\end{sloppypar}
2.625 +
2.626 +\item Limitation of Liability.
2.627 +
2.628 + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
2.629 + WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES
2.630 + AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR
2.631 + DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL
2.632 + DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
2.633 + (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED
2.634 + INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE
2.635 + OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
2.636 + HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
2.637 + DAMAGES.
2.638 +
2.639 +\item Interpretation of Sections 15 and 16.
2.640 +
2.641 +If the disclaimer of warranty and limitation of liability provided
2.642 +above cannot be given local legal effect according to their terms,
2.643 +reviewing courts shall apply local law that most closely approximates
2.644 +an absolute waiver of all civil liability in connection with the
2.645 +Program, unless a warranty or assumption of liability accompanies a
2.646 +copy of the Program in return for a fee.

2.652 +How to Apply These Terms to Your New Programs
2.653 +\end{center}
2.654 +
2.655 +If you develop a new program, and you want it to be of the greatest
2.656 +possible use to the public, the best way to achieve this is to make it
2.657 +free software which everyone can redistribute and change under these terms.
2.658 +
2.659 +To do so, attach the following notices to the program. It is safest
2.660 +to attach them to the start of each source file to most effectively
2.661 +state the exclusion of warranty; and each file should have at least
2.662 +the ``copyright'' line and a pointer to where the full notice is found.
2.663 +

2.667 +
2.668 +Copyright (C) <textyear> <name of author>
2.669 +
2.670 +This program is free software: you can redistribute it and/or modify
2.671 +it under the terms of the GNU Affero General Public License as published by
2.672 +the Free Software Foundation, either version 3 of the License, or
2.673 +(at your option) any later version.
2.674 +
2.675 +This program is distributed in the hope that it will be useful,
2.676 +but WITHOUT ANY WARRANTY; without even the implied warranty of
2.677 +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
2.678 +GNU Affero General Public License for more details.
2.679 +
2.680 +You should have received a copy of the GNU Affero General Public License
2.681 +along with this program. If not, see <http://www.gnu.org/licenses/>.
2.682 +\end{verbatim}
2.683 +}
2.684 +
2.685 +Also add information on how to contact you by electronic and paper mail.
2.686 +
2.687 +If your software can interact with users remotely through a computer
2.688 +network, you should also make sure that it provides a way for users to
2.689 +get its source. For example, if your program is a web application, its
2.690 +interface could display a ``Source'' link that leads users to an archive
2.691 +of the code. There are many ways you could offer source, and different
2.692 +solutions will be better for different programs; see section 13 for the
2.693 +specific requirements.
2.694 +
2.695 +You should also get your employer (if you work as a programmer) or
2.696 +school, if any, to sign a ``copyright disclaimer'' for the program, if
2.697 +necessary. For more information on this, and how to apply and follow
2.698 +the GNU AGPL, see \texttt{http://www.gnu.org/licenses/}.

3.4 + GNU AFFERO GENERAL PUBLIC LICENSE
3.5 + Version 3, 19 November 2007
3.6 +
3.7 + Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
3.8 + Everyone is permitted to copy and distribute verbatim copies
3.9 + of this license document, but changing it is not allowed.
3.10 +
3.11 + Preamble
3.12 +
3.13 + The GNU Affero General Public License is a free, copyleft license for
3.14 +software and other kinds of works, specifically designed to ensure
3.15 +cooperation with the community in the case of network server software.
3.16 +
3.17 + The licenses for most software and other practical works are designed
3.18 +to take away your freedom to share and change the works. By contrast,
3.19 +our General Public Licenses are intended to guarantee your freedom to
3.20 +share and change all versions of a program--to make sure it remains free
3.21 +software for all its users.
3.22 +
3.23 + When we speak of free software, we are referring to freedom, not
3.24 +price. Our General Public Licenses are designed to make sure that you
3.25 +have the freedom to distribute copies of free software (and charge for
3.26 +them if you wish), that you receive source code or can get it if you
3.27 +want it, that you can change the software or use pieces of it in new
3.28 +free programs, and that you know you can do these things.
3.29 +
3.30 + Developers that use our General Public Licenses protect your rights
3.31 +with two steps: (1) assert copyright on the software, and (2) offer
3.32 +you this License which gives you legal permission to copy, distribute
3.33 +and/or modify the software.
3.34 +
3.35 + A secondary benefit of defending all users' freedom is that
3.36 +improvements made in alternate versions of the program, if they
3.37 +receive widespread use, become available for other developers to
3.38 +incorporate. Many developers of free software are heartened and
3.39 +encouraged by the resulting cooperation. However, in the case of
3.40 +software used on network servers, this result may fail to come about.
3.41 +The GNU General Public License permits making a modified version and
3.42 +letting the public access it on a server without ever releasing its
3.43 +source code to the public.
3.44 +
3.45 + The GNU Affero General Public License is designed specifically to
3.46 +ensure that, in such cases, the modified source code becomes available
3.47 +to the community. It requires the operator of a network server to
3.48 +provide the source code of the modified version running there to the
3.49 +users of that server. Therefore, public use of a modified version, on
3.50 +a publicly accessible server, gives the public access to the source
3.51 +code of the modified version.
3.52 +
3.53 + An older license, called the Affero General Public License and
3.54 +published by Affero, was designed to accomplish similar goals. This is
3.55 +a different license, not a version of the Affero GPL, but Affero has
3.56 +released a new version of the Affero GPL which permits relicensing under
3.57 +this license.
3.58 +
3.59 + The precise terms and conditions for copying, distribution and
3.60 +modification follow.
3.61 +
3.62 + TERMS AND CONDITIONS
3.63 +
3.64 + 0. Definitions.
3.65 +
3.66 + "This License" refers to version 3 of the GNU Affero General Public License.
3.67 +
3.68 + "Copyright" also means copyright-like laws that apply to other kinds of
3.69 +works, such as semiconductor masks.
3.70 +
3.71 + "The Program" refers to any copyrightable work licensed under this
3.72 +License. Each licensee is addressed as "you". "Licensees" and
3.73 +"recipients" may be individuals or organizations.
3.74 +
3.75 + To "modify" a work means to copy from or adapt all or part of the work
3.76 +in a fashion requiring copyright permission, other than the making of an
3.77 +exact copy. The resulting work is called a "modified version" of the
3.78 +earlier work or a work "based on" the earlier work.
3.79 +
3.80 + A "covered work" means either the unmodified Program or a work based
3.81 +on the Program.
3.82 +
3.83 + To "propagate" a work means to do anything with it that, without
3.84 +permission, would make you directly or secondarily liable for
3.85 +infringement under applicable copyright law, except executing it on a
3.86 +computer or modifying a private copy. Propagation includes copying,
3.87 +distribution (with or without modification), making available to the
3.88 +public, and in some countries other activities as well.
3.89 +
3.90 + To "convey" a work means any kind of propagation that enables other
3.91 +parties to make or receive copies. Mere interaction with a user through
3.92 +a computer network, with no transfer of a copy, is not conveying.
3.93 +
3.94 + An interactive user interface displays "Appropriate Legal Notices"
3.95 +to the extent that it includes a convenient and prominently visible
3.96 +feature that (1) displays an appropriate copyright notice, and (2)
3.97 +tells the user that there is no warranty for the work (except to the
3.98 +extent that warranties are provided), that licensees may convey the
3.99 +work under this License, and how to view a copy of this License. If
3.100 +the interface presents a list of user commands or options, such as a
3.101 +menu, a prominent item in the list meets this criterion.
3.102 +
3.103 + 1. Source Code.
3.104 +
3.105 + The "source code" for a work means the preferred form of the work
3.106 +for making modifications to it. "Object code" means any non-source
3.107 +form of a work.
3.108 +
3.109 + A "Standard Interface" means an interface that either is an official
3.110 +standard defined by a recognized standards body, or, in the case of
3.111 +interfaces specified for a particular programming language, one that
3.112 +is widely used among developers working in that language.
3.113 +
3.114 + The "System Libraries" of an executable work include anything, other
3.115 +than the work as a whole, that (a) is included in the normal form of
3.116 +packaging a Major Component, but which is not part of that Major
3.117 +Component, and (b) serves only to enable use of the work with that
3.118 +Major Component, or to implement a Standard Interface for which an
3.119 +implementation is available to the public in source code form. A
3.120 +"Major Component", in this context, means a major essential component
3.121 +(kernel, window system, and so on) of the specific operating system
3.122 +(if any) on which the executable work runs, or a compiler used to
3.123 +produce the work, or an object code interpreter used to run it.
3.124 +
3.125 + The "Corresponding Source" for a work in object code form means all
3.126 +the source code needed to generate, install, and (for an executable
3.127 +work) run the object code and to modify the work, including scripts to
3.128 +control those activities. However, it does not include the work's
3.129 +System Libraries, or general-purpose tools or generally available free
3.130 +programs which are used unmodified in performing those activities but
3.131 +which are not part of the work. For example, Corresponding Source
3.132 +includes interface definition files associated with source files for
3.133 +the work, and the source code for shared libraries and dynamically
3.134 +linked subprograms that the work is specifically designed to require,
3.135 +such as by intimate data communication or control flow between those
3.136 +subprograms and other parts of the work.
3.137 +
3.138 + The Corresponding Source need not include anything that users
3.139 +can regenerate automatically from other parts of the Corresponding
3.140 +Source.
3.141 +
3.142 + The Corresponding Source for a work in source code form is that
3.143 +same work.
3.144 +
3.145 + 2. Basic Permissions.
3.146 +
3.147 + All rights granted under this License are granted for the term of
3.148 +copyright on the Program, and are irrevocable provided the stated
3.149 +conditions are met. This License explicitly affirms your unlimited
3.150 +permission to run the unmodified Program. The output from running a
3.151 +covered work is covered by this License only if the output, given its
3.152 +content, constitutes a covered work. This License acknowledges your
3.153 +rights of fair use or other equivalent, as provided by copyright law.
3.154 +
3.155 + You may make, run and propagate covered works that you do not
3.156 +convey, without conditions so long as your license otherwise remains
3.157 +in force. You may convey covered works to others for the sole purpose
3.158 +of having them make modifications exclusively for you, or provide you
3.159 +with facilities for running those works, provided that you comply with
3.160 +the terms of this License in conveying all material for which you do
3.161 +not control copyright. Those thus making or running the covered works
3.162 +for you must do so exclusively on your behalf, under your direction
3.163 +and control, on terms that prohibit them from making any copies of
3.164 +your copyrighted material outside their relationship with you.
3.165 +
3.166 + Conveying under any other circumstances is permitted solely under
3.167 +the conditions stated below. Sublicensing is not allowed; section 10
3.168 +makes it unnecessary.
3.169 +
3.170 + 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
3.171 +
3.172 + No covered work shall be deemed part of an effective technological
3.173 +measure under any applicable law fulfilling obligations under article
3.174 +11 of the WIPO copyright treaty adopted on 20 December 1996, or
3.175 +similar laws prohibiting or restricting circumvention of such
3.176 +measures.
3.177 +
3.178 + When you convey a covered work, you waive any legal power to forbid
3.179 +circumvention of technological measures to the extent such circumvention
3.180 +is effected by exercising rights under this License with respect to
3.181 +the covered work, and you disclaim any intention to limit operation or
3.182 +modification of the work as a means of enforcing, against the work's
3.183 +users, your or third parties' legal rights to forbid circumvention of
3.184 +technological measures.
3.185 +
3.186 + 4. Conveying Verbatim Copies.
3.187 +
3.188 + You may convey verbatim copies of the Program's source code as you
3.189 +receive it, in any medium, provided that you conspicuously and
3.190 +appropriately publish on each copy an appropriate copyright notice;
3.191 +keep intact all notices stating that this License and any
3.192 +non-permissive terms added in accord with section 7 apply to the code;
3.193 +keep intact all notices of the absence of any warranty; and give all
3.194 +recipients a copy of this License along with the Program.
3.195 +
3.196 + You may charge any price or no price for each copy that you convey,
3.197 +and you may offer support or warranty protection for a fee.
3.198 +
3.199 + 5. Conveying Modified Source Versions.
3.200 +
3.201 + You may convey a work based on the Program, or the modifications to
3.202 +produce it from the Program, in the form of source code under the
3.203 +terms of section 4, provided that you also meet all of these conditions:
3.204 +
3.205 + a) The work must carry prominent notices stating that you modified
3.206 + it, and giving a relevant date.
3.207 +
3.208 + b) The work must carry prominent notices stating that it is
3.209 + released under this License and any conditions added under section
3.210 + 7. This requirement modifies the requirement in section 4 to
3.211 + "keep intact all notices".
3.212 +
3.213 + c) You must license the entire work, as a whole, under this
3.214 + License to anyone who comes into possession of a copy. This
3.215 + License will therefore apply, along with any applicable section 7
3.216 + additional terms, to the whole of the work, and all its parts,
3.217 + regardless of how they are packaged. This License gives no
3.218 + permission to license the work in any other way, but it does not
3.219 + invalidate such permission if you have separately received it.
3.220 +
3.221 + d) If the work has interactive user interfaces, each must display
3.222 + Appropriate Legal Notices; however, if the Program has interactive
3.223 + interfaces that do not display Appropriate Legal Notices, your
3.224 + work need not make them do so.
3.225 +
3.226 + A compilation of a covered work with other separate and independent
3.227 +works, which are not by their nature extensions of the covered work,
3.228 +and which are not combined with it such as to form a larger program,
3.229 +in or on a volume of a storage or distribution medium, is called an
3.230 +"aggregate" if the compilation and its resulting copyright are not
3.231 +used to limit the access or legal rights of the compilation's users
3.232 +beyond what the individual works permit. Inclusion of a covered work
3.233 +in an aggregate does not cause this License to apply to the other
3.234 +parts of the aggregate.
3.235 +
3.236 + 6. Conveying Non-Source Forms.
3.237 +
3.238 + You may convey a covered work in object code form under the terms
3.239 +of sections 4 and 5, provided that you also convey the
3.240 +machine-readable Corresponding Source under the terms of this License,
3.241 +in one of these ways:
3.242 +
3.243 + a) Convey the object code in, or embodied in, a physical product
3.244 + (including a physical distribution medium), accompanied by the
3.245 + Corresponding Source fixed on a durable physical medium
3.246 + customarily used for software interchange.
3.247 +
3.248 + b) Convey the object code in, or embodied in, a physical product
3.249 + (including a physical distribution medium), accompanied by a
3.250 + written offer, valid for at least three years and valid for as
3.251 + long as you offer spare parts or customer support for that product
3.252 + model, to give anyone who possesses the object code either (1) a
3.253 + copy of the Corresponding Source for all the software in the
3.254 + product that is covered by this License, on a durable physical
3.255 + medium customarily used for software interchange, for a price no
3.256 + more than your reasonable cost of physically performing this
3.257 + conveying of source, or (2) access to copy the
3.258 + Corresponding Source from a network server at no charge.
3.259 +
3.260 + c) Convey individual copies of the object code with a copy of the
3.261 + written offer to provide the Corresponding Source. This
3.262 + alternative is allowed only occasionally and noncommercially, and
3.263 + only if you received the object code with such an offer, in accord
3.264 + with subsection 6b.
3.265 +
3.266 + d) Convey the object code by offering access from a designated
3.267 + place (gratis or for a charge), and offer equivalent access to the
3.268 + Corresponding Source in the same way through the same place at no
3.269 + further charge. You need not require recipients to copy the
3.270 + Corresponding Source along with the object code. If the place to
3.271 + copy the object code is a network server, the Corresponding Source
3.272 + may be on a different server (operated by you or a third party)
3.273 + that supports equivalent copying facilities, provided you maintain
3.274 + clear directions next to the object code saying where to find the
3.275 + Corresponding Source. Regardless of what server hosts the
3.276 + Corresponding Source, you remain obligated to ensure that it is
3.277 + available for as long as needed to satisfy these requirements.
3.278 +
3.279 + e) Convey the object code using peer-to-peer transmission, provided
3.280 + you inform other peers where the object code and Corresponding
3.281 + Source of the work are being offered to the general public at no
3.282 + charge under subsection 6d.
3.283 +
3.284 + A separable portion of the object code, whose source code is excluded
3.285 +from the Corresponding Source as a System Library, need not be
3.286 +included in conveying the object code work.
3.287 +
3.288 + A "User Product" is either (1) a "consumer product", which means any
3.289 +tangible personal property which is normally used for personal, family,
3.290 +or household purposes, or (2) anything designed or sold for incorporation
3.291 +into a dwelling. In determining whether a product is a consumer product,
3.292 +doubtful cases shall be resolved in favor of coverage. For a particular
3.293 +product received by a particular user, "normally used" refers to a
3.294 +typical or common use of that class of product, regardless of the status
3.295 +of the particular user or of the way in which the particular user
3.296 +actually uses, or expects or is expected to use, the product. A product
3.297 +is a consumer product regardless of whether the product has substantial
3.298 +commercial, industrial or non-consumer uses, unless such uses represent
3.299 +the only significant mode of use of the product.
3.300 +
3.301 + "Installation Information" for a User Product means any methods,
3.302 +procedures, authorization keys, or other information required to install
3.303 +and execute modified versions of a covered work in that User Product from
3.304 +a modified version of its Corresponding Source. The information must
3.305 +suffice to ensure that the continued functioning of the modified object
3.306 +code is in no case prevented or interfered with solely because
3.307 +modification has been made.
3.308 +
3.309 + If you convey an object code work under this section in, or with, or
3.310 +specifically for use in, a User Product, and the conveying occurs as
3.311 +part of a transaction in which the right of possession and use of the
3.312 +User Product is transferred to the recipient in perpetuity or for a
3.313 +fixed term (regardless of how the transaction is characterized), the
3.314 +Corresponding Source conveyed under this section must be accompanied
3.315 +by the Installation Information. But this requirement does not apply
3.316 +if neither you nor any third party retains the ability to install
3.317 +modified object code on the User Product (for example, the work has
3.318 +been installed in ROM).
3.319 +
3.320 + The requirement to provide Installation Information does not include a
3.321 +requirement to continue to provide support service, warranty, or updates
3.322 +for a work that has been modified or installed by the recipient, or for
3.323 +the User Product in which it has been modified or installed. Access to a
3.324 +network may be denied when the modification itself materially and
3.325 +adversely affects the operation of the network or violates the rules and
3.326 +protocols for communication across the network.
3.327 +
3.328 + Corresponding Source conveyed, and Installation Information provided,
3.329 +in accord with this section must be in a format that is publicly
3.330 +documented (and with an implementation available to the public in
3.331 +source code form), and must require no special password or key for
3.332 +unpacking, reading or copying.
3.333 +
3.334 + 7. Additional Terms.
3.335 +
3.336 + "Additional permissions" are terms that supplement the terms of this
3.337 +License by making exceptions from one or more of its conditions.
3.338 +Additional permissions that are applicable to the entire Program shall
3.339 +be treated as though they were included in this License, to the extent
3.340 +that they are valid under applicable law. If additional permissions
3.341 +apply only to part of the Program, that part may be used separately
3.342 +under those permissions, but the entire Program remains governed by
3.343 +this License without regard to the additional permissions.
3.344 +
3.345 + When you convey a copy of a covered work, you may at your option
3.346 +remove any additional permissions from that copy, or from any part of
3.347 +it. (Additional permissions may be written to require their own
3.348 +removal in certain cases when you modify the work.) You may place
3.349 +additional permissions on material, added by you to a covered work,
3.350 +for which you have or can give appropriate copyright permission.
3.351 +
3.352 + Notwithstanding any other provision of this License, for material you
3.353 +add to a covered work, you may (if authorized by the copyright holders of
3.354 +that material) supplement the terms of this License with terms:
3.355 +
3.356 + a) Disclaiming warranty or limiting liability differently from the
3.357 + terms of sections 15 and 16 of this License; or
3.358 +
3.359 + b) Requiring preservation of specified reasonable legal notices or
3.360 + author attributions in that material or in the Appropriate Legal
3.361 + Notices displayed by works containing it; or
3.362 +
3.363 + c) Prohibiting misrepresentation of the origin of that material, or
3.364 + requiring that modified versions of such material be marked in
3.365 + reasonable ways as different from the original version; or
3.366 +
3.367 + d) Limiting the use for publicity purposes of names of licensors or
3.368 + authors of the material; or
3.369 +
3.370 + e) Declining to grant rights under trademark law for use of some
3.371 + trade names, trademarks, or service marks; or
3.372 +
3.373 + f) Requiring indemnification of licensors and authors of that
3.374 + material by anyone who conveys the material (or modified versions of
3.375 + it) with contractual assumptions of liability to the recipient, for
3.376 + any liability that these contractual assumptions directly impose on
3.377 + those licensors and authors.
3.378 +
3.379 + All other non-permissive additional terms are considered "further
3.380 +restrictions" within the meaning of section 10. If the Program as you
3.381 +received it, or any part of it, contains a notice stating that it is
3.382 +governed by this License along with a term that is a further
3.383 +restriction, you may remove that term. If a license document contains
3.384 +a further restriction but permits relicensing or conveying under this
3.385 +License, you may add to a covered work material governed by the terms
3.386 +of that license document, provided that the further restriction does
3.387 +not survive such relicensing or conveying.
3.388 +
3.389 + If you add terms to a covered work in accord with this section, you
3.390 +must place, in the relevant source files, a statement of the
3.391 +additional terms that apply to those files, or a notice indicating
3.392 +where to find the applicable terms.
3.393 +
3.394 + Additional terms, permissive or non-permissive, may be stated in the
3.395 +form of a separately written license, or stated as exceptions;
3.396 +the above requirements apply either way.
3.397 +
3.398 + 8. Termination.
3.399 +
3.400 + You may not propagate or modify a covered work except as expressly
3.401 +provided under this License. Any attempt otherwise to propagate or
3.402 +modify it is void, and will automatically terminate your rights under
3.403 +this License (including any patent licenses granted under the third
3.404 +paragraph of section 11).
3.405 +
3.406 + However, if you cease all violation of this License, then your
3.407 +license from a particular copyright holder is reinstated (a)
3.408 +provisionally, unless and until the copyright holder explicitly and
3.409 +finally terminates your license, and (b) permanently, if the copyright
3.410 +holder fails to notify you of the violation by some reasonable means
3.411 +prior to 60 days after the cessation.
3.412 +
3.413 + Moreover, your license from a particular copyright holder is
3.414 +reinstated permanently if the copyright holder notifies you of the
3.415 +violation by some reasonable means, this is the first time you have
3.416 +received notice of violation of this License (for any work) from that
3.417 +copyright holder, and you cure the violation prior to 30 days after
3.418 +your receipt of the notice.
3.419 +
3.420 + Termination of your rights under this section does not terminate the
3.421 +licenses of parties who have received copies or rights from you under
3.422 +this License. If your rights have been terminated and not permanently
3.423 +reinstated, you do not qualify to receive new licenses for the same
3.424 +material under section 10.
3.425 +
3.426 + 9. Acceptance Not Required for Having Copies.
3.427 +
3.428 + You are not required to accept this License in order to receive or
3.429 +run a copy of the Program. Ancillary propagation of a covered work
3.430 +occurring solely as a consequence of using peer-to-peer transmission
3.431 +to receive a copy likewise does not require acceptance. However,
3.432 +nothing other than this License grants you permission to propagate or
3.433 +modify any covered work. These actions infringe copyright if you do
3.434 +not accept this License. Therefore, by modifying or propagating a
3.435 +covered work, you indicate your acceptance of this License to do so.
3.436 +
3.437 + 10. Automatic Licensing of Downstream Recipients.
3.438 +
3.439 + Each time you convey a covered work, the recipient automatically
3.440 +receives a license from the original licensors, to run, modify and
3.441 +propagate that work, subject to this License. You are not responsible
3.442 +for enforcing compliance by third parties with this License.
3.443 +
3.444 + An "entity transaction" is a transaction transferring control of an
3.445 +organization, or substantially all assets of one, or subdividing an
3.446 +organization, or merging organizations. If propagation of a covered
3.447 +work results from an entity transaction, each party to that
3.448 +transaction who receives a copy of the work also receives whatever
3.449 +licenses to the work the party's predecessor in interest had or could
3.450 +give under the previous paragraph, plus a right to possession of the
3.451 +Corresponding Source of the work from the predecessor in interest, if
3.452 +the predecessor has it or can get it with reasonable efforts.
3.453 +
3.454 + You may not impose any further restrictions on the exercise of the
3.455 +rights granted or affirmed under this License. For example, you may
3.456 +not impose a license fee, royalty, or other charge for exercise of
3.457 +rights granted under this License, and you may not initiate litigation
3.458 +(including a cross-claim or counterclaim in a lawsuit) alleging that
3.459 +any patent claim is infringed by making, using, selling, offering for
3.460 +sale, or importing the Program or any portion of it.
3.461 +
3.462 + 11. Patents.
3.463 +
3.464 + A "contributor" is a copyright holder who authorizes use under this
3.465 +License of the Program or a work on which the Program is based. The
3.466 +work thus licensed is called the contributor's "contributor version".
3.467 +
3.468 + A contributor's "essential patent claims" are all patent claims
3.469 +owned or controlled by the contributor, whether already acquired or
3.470 +hereafter acquired, that would be infringed by some manner, permitted
3.471 +by this License, of making, using, or selling its contributor version,
3.472 +but do not include claims that would be infringed only as a
3.473 +consequence of further modification of the contributor version. For
3.474 +purposes of this definition, "control" includes the right to grant
3.475 +patent sublicenses in a manner consistent with the requirements of
3.476 +this License.
3.477 +
3.478 + Each contributor grants you a non-exclusive, worldwide, royalty-free
3.479 +patent license under the contributor's essential patent claims, to
3.480 +make, use, sell, offer for sale, import and otherwise run, modify and
3.481 +propagate the contents of its contributor version.
3.482 +
3.483 + In the following three paragraphs, a "patent license" is any express
3.484 +agreement or commitment, however denominated, not to enforce a patent
3.485 +(such as an express permission to practice a patent or covenant not to
3.486 +sue for patent infringement). To "grant" such a patent license to a
3.487 +party means to make such an agreement or commitment not to enforce a
3.488 +patent against the party.
3.489 +
3.490 + If you convey a covered work, knowingly relying on a patent license,
3.491 +and the Corresponding Source of the work is not available for anyone
3.492 +to copy, free of charge and under the terms of this License, through a
3.493 +publicly available network server or other readily accessible means,
3.494 +then you must either (1) cause the Corresponding Source to be so
3.495 +available, or (2) arrange to deprive yourself of the benefit of the
3.496 +patent license for this particular work, or (3) arrange, in a manner
3.497 +consistent with the requirements of this License, to extend the patent
3.498 +license to downstream recipients. "Knowingly relying" means you have
3.499 +actual knowledge that, but for the patent license, your conveying the
3.500 +covered work in a country, or your recipient's use of the covered work
3.501 +in a country, would infringe one or more identifiable patents in that
3.502 +country that you have reason to believe are valid.
3.503 +
3.504 + If, pursuant to or in connection with a single transaction or
3.505 +arrangement, you convey, or propagate by procuring conveyance of, a
3.506 +covered work, and grant a patent license to some of the parties
3.507 +receiving the covered work authorizing them to use, propagate, modify
3.508 +or convey a specific copy of the covered work, then the patent license
3.509 +you grant is automatically extended to all recipients of the covered
3.510 +work and works based on it.
3.511 +
3.512 + A patent license is "discriminatory" if it does not include within
3.513 +the scope of its coverage, prohibits the exercise of, or is
3.514 +conditioned on the non-exercise of one or more of the rights that are
3.515 +specifically granted under this License. You may not convey a covered
3.516 +work if you are a party to an arrangement with a third party that is
3.517 +in the business of distributing software, under which you make payment
3.518 +to the third party based on the extent of your activity of conveying
3.519 +the work, and under which the third party grants, to any of the
3.520 +parties who would receive the covered work from you, a discriminatory
3.521 +patent license (a) in connection with copies of the covered work
3.522 +conveyed by you (or copies made from those copies), or (b) primarily
3.523 +for and in connection with specific products or compilations that
3.524 +contain the covered work, unless you entered into that arrangement,
3.525 +or that patent license was granted, prior to 28 March 2007.
3.526 +
3.527 + Nothing in this License shall be construed as excluding or limiting
3.528 +any implied license or other defenses to infringement that may
3.529 +otherwise be available to you under applicable patent law.
3.530 +
3.531 + 12. No Surrender of Others' Freedom.
3.532 +
3.533 + If conditions are imposed on you (whether by court order, agreement or
3.534 +otherwise) that contradict the conditions of this License, they do not
3.535 +excuse you from the conditions of this License. If you cannot convey a
3.536 +covered work so as to satisfy simultaneously your obligations under this
3.537 +License and any other pertinent obligations, then as a consequence you may
3.538 +not convey it at all. For example, if you agree to terms that obligate you
3.539 +to collect a royalty for further conveying from those to whom you convey
3.540 +the Program, the only way you could satisfy both those terms and this
3.541 +License would be to refrain entirely from conveying the Program.
3.542 +
3.543 + 13. Remote Network Interaction; Use with the GNU General Public License.
3.544 +
3.545 + Notwithstanding any other provision of this License, if you modify the
3.546 +Program, your modified version must prominently offer all users
3.547 +interacting with it remotely through a computer network (if your version
3.548 +supports such interaction) an opportunity to receive the Corresponding
3.549 +Source of your version by providing access to the Corresponding Source
3.550 +from a network server at no charge, through some standard or customary
3.551 +means of facilitating copying of software. This Corresponding Source
3.552 +shall include the Corresponding Source for any work covered by version 3
3.553 +of the GNU General Public License that is incorporated pursuant to the
3.554 +following paragraph.
3.555 +
3.556 + Notwithstanding any other provision of this License, you have
3.557 +permission to link or combine any covered work with a work licensed
3.558 +under version 3 of the GNU General Public License into a single
3.559 +combined work, and to convey the resulting work. The terms of this
3.560 +License will continue to apply to the part which is the covered work,
3.561 +but the work with which it is combined will remain governed by version
3.562 +3 of the GNU General Public License.
3.563 +
3.564 + 14. Revised Versions of this License.
3.565 +
3.566 + The Free Software Foundation may publish revised and/or new versions of
3.567 +the GNU Affero General Public License from time to time. Such new versions
3.568 +will be similar in spirit to the present version, but may differ in detail to
3.569 +address new problems or concerns.
3.570 +
3.571 + Each version is given a distinguishing version number. If the
3.572 +Program specifies that a certain numbered version of the GNU Affero General
3.573 +Public License "or any later version" applies to it, you have the
3.574 +option of following the terms and conditions either of that numbered
3.575 +version or of any later version published by the Free Software
3.576 +Foundation. If the Program does not specify a version number of the
3.577 +GNU Affero General Public License, you may choose any version ever published
3.578 +by the Free Software Foundation.
3.579 +
3.580 + If the Program specifies that a proxy can decide which future
3.581 +versions of the GNU Affero General Public License can be used, that proxy's
3.582 +public statement of acceptance of a version permanently authorizes you
3.583 +to choose that version for the Program.
3.584 +
3.585 + Later license versions may give you additional or different
3.586 +permissions. However, no additional obligations are imposed on any
3.587 +author or copyright holder as a result of your choosing to follow a
3.588 +later version.
3.589 +
3.590 + 15. Disclaimer of Warranty.
3.591 +
3.592 + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
3.593 +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
3.594 +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
3.595 +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
3.596 +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
3.597 +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
3.598 +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
3.599 +ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
3.600 +
3.601 + 16. Limitation of Liability.
3.602 +
3.603 + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
3.604 +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
3.605 +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
3.606 +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE

3.616 +above cannot be given local legal effect according to their terms,
3.617 +reviewing courts shall apply local law that most closely approximates
3.618 +an absolute waiver of all civil liability in connection with the
3.619 +Program, unless a warranty or assumption of liability accompanies a
3.620 +copy of the Program in return for a fee.

3.623 +
3.624 + How to Apply These Terms to Your New Programs
3.625 +
3.626 + If you develop a new program, and you want it to be of the greatest
3.627 +possible use to the public, the best way to achieve this is to make it
3.628 +free software which everyone can redistribute and change under these terms.
3.629 +
3.630 + To do so, attach the following notices to the program. It is safest
3.631 +to attach them to the start of each source file to most effectively
3.632 +state the exclusion of warranty; and each file should have at least
3.633 +the "copyright" line and a pointer to where the full notice is found.
3.634 +
3.635 + <one line to give the program's name and a brief idea of what it does.>
3.636 + Copyright (C) <year> <name of author>
3.637 +
3.638 + This program is free software: you can redistribute it and/or modify
3.639 + it under the terms of the GNU Affero General Public License as published by
3.640 + the Free Software Foundation, either version 3 of the License, or
3.641 + (at your option) any later version.
3.642 +
3.643 + This program is distributed in the hope that it will be useful,
3.644 + but WITHOUT ANY WARRANTY; without even the implied warranty of
3.645 + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
3.646 + GNU Affero General Public License for more details.
3.647 +
3.648 + You should have received a copy of the GNU Affero General Public License
3.649 + along with this program. If not, see <http://www.gnu.org/licenses/>.
3.650 +
3.651 +Also add information on how to contact you by electronic and paper mail.
3.652 +
3.653 + If your software can interact with users remotely through a computer
3.654 +network, you should also make sure that it provides a way for users to
3.655 +get its source. For example, if your program is a web application, its
3.656 +interface could display a "Source" link that leads users to an archive
3.657 +of the code. There are many ways you could offer source, and different
3.658 +solutions will be better for different programs; see section 13 for the
3.659 +specific requirements.
3.660 +
3.661 + You should also get your employer (if you work as a programmer) or school,
3.662 +if any, to sign a "copyright disclaimer" for the program, if necessary.
