0002 <p style="text-align: center;">Version 3, 19 November 2007</p>
0003 
0004 <p>Copyright © 2007 Free Software Foundation, Inc.
0005  &lt;<a href="https://fsf.org/">https://fsf.org/</a>&gt;</p><p>
0006  Everyone is permitted to copy and distribute verbatim copies
0007  of this license document, but changing it is not allowed.</p>
0008 
0009 <h3><a name="preamble"></a>Preamble</h3>
0010 
0011 <p>The GNU Affero General Public License is a free, copyleft license 
0012 for software and other kinds of works, specifically designed to ensure 
0013 cooperation with the community in the case of network server software.</p>
0014 
0015 <p>The licenses for most software and other practical works are designed 
0016 to take away your freedom to share and change the works.  By contrast, 
0017 our General Public Licenses are intended to guarantee your freedom to 
0018 share and change all versions of a program--to make sure it remains free 
0019 software for all its users.</p>
0020 
0021 <p>When we speak of free software, we are referring to freedom, not 
0022 price.  Our General Public Licenses are designed to make sure that you 
0023 have the freedom to distribute copies of free software (and charge for 
0024 them if you wish), that you receive source code or can get it if you 
0025 want it, that you can change the software or use pieces of it in new 
0026 free programs, and that you know you can do these things.</p>
0027 
0028 <p>Developers that use our General Public Licenses protect your rights 
0029 with two steps: (1) assert copyright on the software, and (2) offer 
0030 you this License which gives you legal permission to copy, distribute 
0031 and/or modify the software.</p>
0032 
0033 <p>A secondary benefit of defending all users' freedom is that 
0034 improvements made in alternate versions of the program, if they 
0035 receive widespread use, become available for other developers to 
0036 incorporate.  Many developers of free software are heartened and 
0037 encouraged by the resulting cooperation.  However, in the case of 
0038 software used on network servers, this result may fail to come about. 
0039 The GNU General Public License permits making a modified version and 
0040 letting the public access it on a server without ever releasing its 
0041 source code to the public.</p>
0042 
0043 <p>The GNU Affero General Public License is designed specifically to 
0044 ensure that, in such cases, the modified source code becomes available 
0045 to the community.  It requires the operator of a network server to 
0046 provide the source code of the modified version running there to the 
0047 users of that server.  Therefore, public use of a modified version, on 
0048 a publicly accessible server, gives the public access to the source 
0049 code of the modified version.</p>
0050 
0051 <p>An older license, called the Affero General Public License and 
0052 published by Affero, was designed to accomplish similar goals.  This is 
0053 a different license, not a version of the Affero GPL, but Affero has 
0054 released a new version of the Affero GPL which permits relicensing under 
0055 this license.</p>
0056 
0057 <p>The precise terms and conditions for copying, distribution and 
0058 modification follow.</p>
0059 
0060 <h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
0061 
0062 <h4><a name="section0"></a>0. Definitions.</h4>
0063 
0064 <p>"This License" refers to version 3 of the GNU Affero General Public 
0065 License.</p>
0066 
0067 <p>"Copyright" also means copyright-like laws that apply to other kinds 
0068 of works, such as semiconductor masks.</p>
0069 
0070 <p>"The Program" refers to any copyrightable work licensed under this 
0071 License.  Each licensee is addressed as "you".  "Licensees" and 
0072 "recipients" may be individuals or organizations.</p>
0073 
0074 <p>To "modify" a work means to copy from or adapt all or part of the work 
0075 in a fashion requiring copyright permission, other than the making of an 
0076 exact copy.  The resulting work is called a "modified version" of the 
0077 earlier work or a work "based on" the earlier work.</p>
0078 
0079 <p>A "covered work" means either the unmodified Program or a work based 
0080 on the Program.</p>
0081 
0082 <p>To "propagate" a work means to do anything with it that, without 
0083 permission, would make you directly or secondarily liable for 
0084 infringement under applicable copyright law, except executing it on a 
0085 computer or modifying a private copy.  Propagation includes copying, 
0086 distribution (with or without modification), making available to the 
0087 public, and in some countries other activities as well.</p>
0088 
0089 <p>To "convey" a work means any kind of propagation that enables other 
0090 parties to make or receive copies.  Mere interaction with a user through 
0091 a computer network, with no transfer of a copy, is not conveying.</p>
0092 
0093 <p>An interactive user interface displays "Appropriate Legal Notices" 
0094 to the extent that it includes a convenient and prominently visible 
0095 feature that (1) displays an appropriate copyright notice, and (2) 
0096 tells the user that there is no warranty for the work (except to the 
0097 extent that warranties are provided), that licensees may convey the 
0098 work under this License, and how to view a copy of this License.  If 
0099 the interface presents a list of user commands or options, such as a 
0100 menu, a prominent item in the list meets this criterion.</p>
0101 
0102 <h4><a name="section1"></a>1. Source Code.</h4>
0103 
0104 <p>The "source code" for a work means the preferred form of the work 
0105 for making modifications to it.  "Object code" means any non-source 
0106 form of a work.</p>
0107 
0108 <p>A "Standard Interface" means an interface that either is an official 
0109 standard defined by a recognized standards body, or, in the case of 
0110 interfaces specified for a particular programming language, one that 
0111 is widely used among developers working in that language.</p>
0112 
0113 <p>The "System Libraries" of an executable work include anything, other 
0114 than the work as a whole, that (a) is included in the normal form of 
0115 packaging a Major Component, but which is not part of that Major 
0116 Component, and (b) serves only to enable use of the work with that 
0117 Major Component, or to implement a Standard Interface for which an 
0118 implementation is available to the public in source code form.  A 
0119 "Major Component", in this context, means a major essential component 
0120 (kernel, window system, and so on) of the specific operating system 
0121 (if any) on which the executable work runs, or a compiler used to 
0122 produce the work, or an object code interpreter used to run it.</p>
0123 
0124 <p>The "Corresponding Source" for a work in object code form means all 
0125 the source code needed to generate, install, and (for an executable 
0126 work) run the object code and to modify the work, including scripts to 
0127 control those activities.  However, it does not include the work's 
0128 System Libraries, or general-purpose tools or generally available free 
0129 programs which are used unmodified in performing those activities but 
0130 which are not part of the work.  For example, Corresponding Source 
0131 includes interface definition files associated with source files for 
0132 the work, and the source code for shared libraries and dynamically 
0133 linked subprograms that the work is specifically designed to require, 
0134 such as by intimate data communication or control flow between those 
0135 subprograms and other parts of the work.</p>
0136 
0137 <p>The Corresponding Source need not include anything that users 
0138 can regenerate automatically from other parts of the Corresponding 
0139 Source.</p>
0140 
0141 <p>The Corresponding Source for a work in source code form is that 
0142 same work.</p>
0143 
0144 <h4><a name="section2"></a>2. Basic Permissions.</h4>
0145 
0146 <p>All rights granted under this License are granted for the term of 
0147 copyright on the Program, and are irrevocable provided the stated 
0148 conditions are met.  This License explicitly affirms your unlimited 
0149 permission to run the unmodified Program.  The output from running a 
0150 covered work is covered by this License only if the output, given its 
0151 content, constitutes a covered work.  This License acknowledges your 
0152 rights of fair use or other equivalent, as provided by copyright law.</p>
0153 
0154 <p>You may make, run and propagate covered works that you do not 
0155 convey, without conditions so long as your license otherwise remains 
0156 in force.  You may convey covered works to others for the sole purpose 
0157 of having them make modifications exclusively for you, or provide you 
0158 with facilities for running those works, provided that you comply with 
0159 the terms of this License in conveying all material for which you do 
0160 not control copyright.  Those thus making or running the covered works 
0161 for you must do so exclusively on your behalf, under your direction 
0162 and control, on terms that prohibit them from making any copies of 
0163 your copyrighted material outside their relationship with you.</p>
0164 
0165 <p>Conveying under any other circumstances is permitted solely under 
0166 the conditions stated below.  Sublicensing is not allowed; section 10 
0167 makes it unnecessary.</p>
0168 
0169 <h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
0170 
0171 <p>No covered work shall be deemed part of an effective technological 
0172 measure under any applicable law fulfilling obligations under article 
0173 11 of the WIPO copyright treaty adopted on 20 December 1996, or 
0174 similar laws prohibiting or restricting circumvention of such 
0175 measures.</p>
0176 
0177 <p>When you convey a covered work, you waive any legal power to forbid 
0178 circumvention of technological measures to the extent such circumvention 
0179 is effected by exercising rights under this License with respect to 
0180 the covered work, and you disclaim any intention to limit operation or 
0181 modification of the work as a means of enforcing, against the work's 
0182 users, your or third parties' legal rights to forbid circumvention of 
0183 technological measures.</p>
0184 
0185 <h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
0186 
0187 <p>You may convey verbatim copies of the Program's source code as you 
0188 receive it, in any medium, provided that you conspicuously and 
0189 appropriately publish on each copy an appropriate copyright notice; 
0190 keep intact all notices stating that this License and any 
0191 non-permissive terms added in accord with section 7 apply to the code; 
0192 keep intact all notices of the absence of any warranty; and give all 
0193 recipients a copy of this License along with the Program.</p>
0194 
0195 <p>You may charge any price or no price for each copy that you convey, 
0196 and you may offer support or warranty protection for a fee.</p>
0197 
0198 <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
0199 
0200 <p>You may convey a work based on the Program, or the modifications to 
0201 produce it from the Program, in the form of source code under the 
0202 terms of section 4, provided that you also meet all of these conditions:</p>
0203 
0204 <ul>
0205 
0206 <li>a) The work must carry prominent notices stating that you modified
0207     it, and giving a relevant date.</li>
0208 
0209 <li>b) The work must carry prominent notices stating that it is
0210     released under this License and any conditions added under section
0211     7.  This requirement modifies the requirement in section 4 to
0212     "keep intact all notices".</li>
0213 
0214 <li>c) You must license the entire work, as a whole, under this
0215     License to anyone who comes into possession of a copy.  This
0216     License will therefore apply, along with any applicable section 7
0217     additional terms, to the whole of the work, and all its parts,
0218     regardless of how they are packaged.  This License gives no
0219     permission to license the work in any other way, but it does not
0220     invalidate such permission if you have separately received it.</li>
0221 
0222 <li>d) If the work has interactive user interfaces, each must display
0223     Appropriate Legal Notices; however, if the Program has interactive
0224     interfaces that do not display Appropriate Legal Notices, your
0225     work need not make them do so.</li>
0226 
0227 </ul>
0228 
0229 <p>A compilation of a covered work with other separate and independent 
0230 works, which are not by their nature extensions of the covered work, 
0231 and which are not combined with it such as to form a larger program, 
0232 in or on a volume of a storage or distribution medium, is called an 
0233 "aggregate" if the compilation and its resulting copyright are not 
0234 used to limit the access or legal rights of the compilation's users 
0235 beyond what the individual works permit.  Inclusion of a covered work 
0236 in an aggregate does not cause this License to apply to the other 
0237 parts of the aggregate.</p>
0238 
0239 <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
0240 
0241 <p>You may convey a covered work in object code form under the terms 
0242 of sections 4 and 5, provided that you also convey the 
0243 machine-readable Corresponding Source under the terms of this License, 
0244 in one of these ways:</p>
0245 
0246 <ul>
0247 
0248 <li>a) Convey the object code in, or embodied in, a physical product
0249     (including a physical distribution medium), accompanied by the
0250     Corresponding Source fixed on a durable physical medium
0251     customarily used for software interchange.</li>
0252 
0253 <li>b) Convey the object code in, or embodied in, a physical product
0254     (including a physical distribution medium), accompanied by a
0255     written offer, valid for at least three years and valid for as
0256     long as you offer spare parts or customer support for that product
0257     model, to give anyone who possesses the object code either (1) a
0258     copy of the Corresponding Source for all the software in the
0259     product that is covered by this License, on a durable physical
0260     medium customarily used for software interchange, for a price no
0261     more than your reasonable cost of physically performing this
0262     conveying of source, or (2) access to copy the
0263     Corresponding Source from a network server at no charge.</li>
0264 
0265 <li>c) Convey individual copies of the object code with a copy of the
0266     written offer to provide the Corresponding Source.  This
0267     alternative is allowed only occasionally and noncommercially, and
0268     only if you received the object code with such an offer, in accord
0269     with subsection 6b.</li>
0270 
0271 <li>d) Convey the object code by offering access from a designated
0272     place (gratis or for a charge), and offer equivalent access to the
0273     Corresponding Source in the same way through the same place at no
0274     further charge.  You need not require recipients to copy the
0275     Corresponding Source along with the object code.  If the place to
0276     copy the object code is a network server, the Corresponding Source
0277     may be on a different server (operated by you or a third party)
0278     that supports equivalent copying facilities, provided you maintain
0279     clear directions next to the object code saying where to find the
0280     Corresponding Source.  Regardless of what server hosts the
0281     Corresponding Source, you remain obligated to ensure that it is
0282     available for as long as needed to satisfy these requirements.</li>
0283 
0284 <li>e) Convey the object code using peer-to-peer transmission, provided
0285     you inform other peers where the object code and Corresponding
0286     Source of the work are being offered to the general public at no
0287     charge under subsection 6d.</li>
0288 
0289 </ul>
0290 
0291 <p>A separable portion of the object code, whose source code is excluded 
0292 from the Corresponding Source as a System Library, need not be 
0293 included in conveying the object code work.</p>
0294 
0295 <p>A "User Product" is either (1) a "consumer product", which means any 
0296 tangible personal property which is normally used for personal, family, 
0297 or household purposes, or (2) anything designed or sold for incorporation 
0298 into a dwelling.  In determining whether a product is a consumer product, 
0299 doubtful cases shall be resolved in favor of coverage.  For a particular 
0300 product received by a particular user, "normally used" refers to a 
0301 typical or common use of that class of product, regardless of the status 
0302 of the particular user or of the way in which the particular user 
0303 actually uses, or expects or is expected to use, the product.  A product 
0304 is a consumer product regardless of whether the product has substantial 
0305 commercial, industrial or non-consumer uses, unless such uses represent 
0306 the only significant mode of use of the product.</p>
0307 
0308 <p>"Installation Information" for a User Product means any methods, 
0309 procedures, authorization keys, or other information required to install 
0310 and execute modified versions of a covered work in that User Product from 
0311 a modified version of its Corresponding Source.  The information must 
0312 suffice to ensure that the continued functioning of the modified object 
0313 code is in no case prevented or interfered with solely because 
0314 modification has been made.</p>
0315 
0316 <p>If you convey an object code work under this section in, or with, or 
0317 specifically for use in, a User Product, and the conveying occurs as 
0318 part of a transaction in which the right of possession and use of the 
0319 User Product is transferred to the recipient in perpetuity or for a 
0320 fixed term (regardless of how the transaction is characterized), the 
0321 Corresponding Source conveyed under this section must be accompanied 
0322 by the Installation Information.  But this requirement does not apply 
0323 if neither you nor any third party retains the ability to install 
0324 modified object code on the User Product (for example, the work has 
0325 been installed in ROM).</p>
0326 
0327 <p>The requirement to provide Installation Information does not include a 
0328 requirement to continue to provide support service, warranty, or updates 
0329 for a work that has been modified or installed by the recipient, or for 
0330 the User Product in which it has been modified or installed.  Access to a 
0331 network may be denied when the modification itself materially and 
0332 adversely affects the operation of the network or violates the rules and 
0333 protocols for communication across the network.</p>
0334 
0335 <p>Corresponding Source conveyed, and Installation Information provided, 
0336 in accord with this section must be in a format that is publicly 
0337 documented (and with an implementation available to the public in 
0338 source code form), and must require no special password or key for 
0339 unpacking, reading or copying.</p>
0340 
0341 <h4><a name="section7"></a>7. Additional Terms.</h4>
0342 
0343 <p>"Additional permissions" are terms that supplement the terms of this 
0344 License by making exceptions from one or more of its conditions. 
0345 Additional permissions that are applicable to the entire Program shall 
0346 be treated as though they were included in this License, to the extent 
0347 that they are valid under applicable law.  If additional permissions 
0348 apply only to part of the Program, that part may be used separately 
0349 under those permissions, but the entire Program remains governed by 
0350 this License without regard to the additional permissions.</p>
0351 
0352 <p>When you convey a copy of a covered work, you may at your option 
0353 remove any additional permissions from that copy, or from any part of 
0354 it.  (Additional permissions may be written to require their own 
0355 removal in certain cases when you modify the work.)  You may place 
0356 additional permissions on material, added by you to a covered work, 
0357 for which you have or can give appropriate copyright permission.</p>
0358 
0359 <p>Notwithstanding any other provision of this License, for material you 
0360 add to a covered work, you may (if authorized by the copyright holders of 
0361 that material) supplement the terms of this License with terms:</p>
0362 
0363 <ul>
0364 
0365 <li>a) Disclaiming warranty or limiting liability differently from the
0366     terms of sections 15 and 16 of this License; or</li>
0367 
0368 <li>b) Requiring preservation of specified reasonable legal notices or
0369     author attributions in that material or in the Appropriate Legal
0370     Notices displayed by works containing it; or</li>
0371 
0372 <li>c) Prohibiting misrepresentation of the origin of that material, or
0373     requiring that modified versions of such material be marked in
0374     reasonable ways as different from the original version; or</li>
0375 
0376 <li>d) Limiting the use for publicity purposes of names of licensors or
0377     authors of the material; or</li>
0378 
0379 <li>e) Declining to grant rights under trademark law for use of some
0380     trade names, trademarks, or service marks; or</li>
0381 
0382 <li>f) Requiring indemnification of licensors and authors of that
0383     material by anyone who conveys the material (or modified versions of
0384     it) with contractual assumptions of liability to the recipient, for
0385     any liability that these contractual assumptions directly impose on
0386     those licensors and authors.</li>
0387 
0388 </ul>
0389 
0390 <p>All other non-permissive additional terms are considered "further 
0391 restrictions" within the meaning of section 10.  If the Program as you 
0392 received it, or any part of it, contains a notice stating that it is 
0393 governed by this License along with a term that is a further restriction, 
0394 you may remove that term.  If a license document contains a further 
0395 restriction but permits relicensing or conveying under this License, you 
0396 may add to a covered work material governed by the terms of that license 
0397 document, provided that the further restriction does not survive such 
0398 relicensing or conveying.</p>
0399 
0400 <p>If you add terms to a covered work in accord with this section, you 
0401 must place, in the relevant source files, a statement of the 
0402 additional terms that apply to those files, or a notice indicating 
0403 where to find the applicable terms.</p>
0404 
0405 <p>Additional terms, permissive or non-permissive, may be stated in the 
0406 form of a separately written license, or stated as exceptions; 
0407 the above requirements apply either way.</p>
0408 
0409 <h4><a name="section8"></a>8. Termination.</h4>
0410 
0411 <p>You may not propagate or modify a covered work except as expressly 
0412 provided under this License.  Any attempt otherwise to propagate or 
0413 modify it is void, and will automatically terminate your rights under 
0414 this License (including any patent licenses granted under the third 
0415 paragraph of section 11).</p>
0416 
0417 <p>However, if you cease all violation of this License, then your 
0418 license from a particular copyright holder is reinstated (a) 
0419 provisionally, unless and until the copyright holder explicitly and 
0420 finally terminates your license, and (b) permanently, if the copyright 
0421 holder fails to notify you of the violation by some reasonable means 
0422 prior to 60 days after the cessation.</p>
0423 
0424 <p>Moreover, your license from a particular copyright holder is 
0425 reinstated permanently if the copyright holder notifies you of the 
0426 violation by some reasonable means, this is the first time you have 
0427 received notice of violation of this License (for any work) from that 
0428 copyright holder, and you cure the violation prior to 30 days after 
0429 your receipt of the notice.</p>
0430 
0431 <p>Termination of your rights under this section does not terminate the 
0432 licenses of parties who have received copies or rights from you under 
0433 this License.  If your rights have been terminated and not permanently 
0434 reinstated, you do not qualify to receive new licenses for the same 
0435 material under section 10.</p>
0436 
0437 <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
0438 
0439 <p>You are not required to accept this License in order to receive or 
0440 run a copy of the Program.  Ancillary propagation of a covered work 
0441 occurring solely as a consequence of using peer-to-peer transmission 
0442 to receive a copy likewise does not require acceptance.  However, 
0443 nothing other than this License grants you permission to propagate or 
0444 modify any covered work.  These actions infringe copyright if you do 
0445 not accept this License.  Therefore, by modifying or propagating a 
0446 covered work, you indicate your acceptance of this License to do so.</p>
0447 
0448 <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
0449 
0450 <p>Each time you convey a covered work, the recipient automatically 
0451 receives a license from the original licensors, to run, modify and 
0452 propagate that work, subject to this License.  You are not responsible 
0453 for enforcing compliance by third parties with this License.</p>
0454 
0455 <p>An "entity transaction" is a transaction transferring control of an 
0456 organization, or substantially all assets of one, or subdividing an 
0457 organization, or merging organizations.  If propagation of a covered 
0458 work results from an entity transaction, each party to that 
0459 transaction who receives a copy of the work also receives whatever 
0460 licenses to the work the party's predecessor in interest had or could 
0461 give under the previous paragraph, plus a right to possession of the 
0462 Corresponding Source of the work from the predecessor in interest, if 
0463 the predecessor has it or can get it with reasonable efforts.</p>
0464 
0465 <p>You may not impose any further restrictions on the exercise of the 
0466 rights granted or affirmed under this License.  For example, you may 
0467 not impose a license fee, royalty, or other charge for exercise of 
0468 rights granted under this License, and you may not initiate litigation 
0469 (including a cross-claim or counterclaim in a lawsuit) alleging that 
0470 any patent claim is infringed by making, using, selling, offering for 
0471 sale, or importing the Program or any portion of it.</p>
0472 
0473 <h4><a name="section11"></a>11. Patents.</h4>
0474 
0475 <p>A "contributor" is a copyright holder who authorizes use under this 
0476 License of the Program or a work on which the Program is based.  The 
0477 work thus licensed is called the contributor's "contributor version".</p>
0478 
0479 <p>A contributor's "essential patent claims" are all patent claims 
0480 owned or controlled by the contributor, whether already acquired or 
0481 hereafter acquired, that would be infringed by some manner, permitted 
0482 by this License, of making, using, or selling its contributor version, 
0483 but do not include claims that would be infringed only as a 
0484 consequence of further modification of the contributor version.  For 
0485 purposes of this definition, "control" includes the right to grant 
0486 patent sublicenses in a manner consistent with the requirements of 
0487 this License.</p>
0488 
0489 <p>Each contributor grants you a non-exclusive, worldwide, royalty-free 
0490 patent license under the contributor's essential patent claims, to 
0491 make, use, sell, offer for sale, import and otherwise run, modify and 
0492 propagate the contents of its contributor version.</p>
0493 
0494 <p>In the following three paragraphs, a "patent license" is any express 
0495 agreement or commitment, however denominated, not to enforce a patent 
0496 (such as an express permission to practice a patent or covenant not to 
0497 sue for patent infringement).  To "grant" such a patent license to a 
0498 party means to make such an agreement or commitment not to enforce a 
0499 patent against the party.</p>
0500 
0501 <p>If you convey a covered work, knowingly relying on a patent license, 
0502 and the Corresponding Source of the work is not available for anyone 
0503 to copy, free of charge and under the terms of this License, through a 
0504 publicly available network server or other readily accessible means, 
0505 then you must either (1) cause the Corresponding Source to be so 
0506 available, or (2) arrange to deprive yourself of the benefit of the 
0507 patent license for this particular work, or (3) arrange, in a manner 
0508 consistent with the requirements of this License, to extend the patent 
0509 license to downstream recipients.  "Knowingly relying" means you have 
0510 actual knowledge that, but for the patent license, your conveying the 
0511 covered work in a country, or your recipient's use of the covered work 
0512 in a country, would infringe one or more identifiable patents in that 
0513 country that you have reason to believe are valid.</p>
0514 
0515 <p>If, pursuant to or in connection with a single transaction or 
0516 arrangement, you convey, or propagate by procuring conveyance of, a 
0517 covered work, and grant a patent license to some of the parties 
0518 receiving the covered work authorizing them to use, propagate, modify 
0519 or convey a specific copy of the covered work, then the patent license 
0520 you grant is automatically extended to all recipients of the covered 
0521 work and works based on it.</p>
0522 
0523 <p>A patent license is "discriminatory" if it does not include within 
0524 the scope of its coverage, prohibits the exercise of, or is 
0525 conditioned on the non-exercise of one or more of the rights that are 
0526 specifically granted under this License.  You may not convey a covered 
0527 work if you are a party to an arrangement with a third party that is 
0528 in the business of distributing software, under which you make payment 
0529 to the third party based on the extent of your activity of conveying 
0530 the work, and under which the third party grants, to any of the 
0531 parties who would receive the covered work from you, a discriminatory 
0532 patent license (a) in connection with copies of the covered work 
0533 conveyed by you (or copies made from those copies), or (b) primarily 
0534 for and in connection with specific products or compilations that 
0535 contain the covered work, unless you entered into that arrangement, 
0536 or that patent license was granted, prior to 28 March 2007.</p>
0537 
0538 <p>Nothing in this License shall be construed as excluding or limiting 
0539 any implied license or other defenses to infringement that may 
0540 otherwise be available to you under applicable patent law.</p>
0541 
0542 <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
0543 
0544 <p>If conditions are imposed on you (whether by court order, agreement or 
0545 otherwise) that contradict the conditions of this License, they do not 
0546 excuse you from the conditions of this License.  If you cannot convey a 
0547 covered work so as to satisfy simultaneously your obligations under this 
0548 License and any other pertinent obligations, then as a consequence you may 
0549 not convey it at all.  For example, if you agree to terms that obligate you 
0550 to collect a royalty for further conveying from those to whom you convey 
0551 the Program, the only way you could satisfy both those terms and this 
0552 License would be to refrain entirely from conveying the Program.</p>
0553 
0554 <h4><a name="section13"></a>13. Remote Network Interaction; Use with the GNU General Public License.</h4>
0555 
0556 <p>Notwithstanding any other provision of this License, if you modify the 
0557 Program, your modified version must prominently offer all users 
0558 interacting with it remotely through a computer network (if your version 
0559 supports such interaction) an opportunity to receive the Corresponding 
0560 Source of your version by providing access to the Corresponding Source 
0561 from a network server at no charge, through some standard or customary 
0562 means of facilitating copying of software.  This Corresponding Source 
0563 shall include the Corresponding Source for any work covered by version 3 
0564 of the GNU General Public License that is incorporated pursuant to the 
0565 following paragraph.</p>
0566 
0567 <p>Notwithstanding any other provision of this License, you have permission 
0568 to link or combine any covered work with a work licensed under version 3 
0569 of the GNU General Public License into a single combined work, and to 
0570 convey the resulting work.  The terms of this License will continue to 
0571 apply to the part which is the covered work, but the work with which it is 
0572 combined will remain governed by version 3 of the GNU General Public 
0573 License.</p>
0574 
0575 <h4><a name="section14"></a>14. Revised Versions of this License.</h4>
0576 
0577 <p>The Free Software Foundation may publish revised and/or new versions of 
0578 the GNU Affero General Public License from time to time.  Such new 
0579 versions will be similar in spirit to the present version, but may differ 
0580 in detail to address new problems or concerns.</p>
0581 
0582 <p>Each version is given a distinguishing version number.  If the 
0583 Program specifies that a certain numbered version of the GNU Affero 
0584 General Public License "or any later version" applies to it, you have 
0585 the option of following the terms and conditions either of that 
0586 numbered version or of any later version published by the Free 
0587 Software Foundation.  If the Program does not specify a version number 
0588 of the GNU Affero General Public License, you may choose any version 
0589 ever published by the Free Software Foundation.</p>
0590 
0591 <p>If the Program specifies that a proxy can decide which future 
0592 versions of the GNU Affero General Public License can be used, that 
0593 proxy's public statement of acceptance of a version permanently 
0594 authorizes you to choose that version for the Program.</p>
0595 
0596 <p>Later license versions may give you additional or different 
0597 permissions.  However, no additional obligations are imposed on any 
0598 author or copyright holder as a result of your choosing to follow a 
0599 later version.</p>
0600 
0601 <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
0602 
0603 <p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 
0604 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 
0605 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 
0606 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 
0607 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 
0608 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 
0609 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 
0610 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
0611 
0612 <h4><a name="section16"></a>16. Limitation of Liability.</h4>
0613 
0614 <p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 
0615 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 
0616 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 
0617 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 
0618 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 
0619 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 
0620 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 
0621 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 
0622 SUCH DAMAGES.</p>
0623 
0624 <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
0625 
0626 <p>If the disclaimer of warranty and limitation of liability provided 
0627 above cannot be given local legal effect according to their terms, 
0628 reviewing courts shall apply local law that most closely approximates 
0629 an absolute waiver of all civil liability in connection with the 
0630 Program, unless a warranty or assumption of liability accompanies a 
0631 copy of the Program in return for a fee.</p>
0632 
0633 <p>END OF TERMS AND CONDITIONS</p>
0634 
0635 <h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
0636 
0637 <p>If you develop a new program, and you want it to be of the greatest 
0638 possible use to the public, the best way to achieve this is to make it 
0639 free software which everyone can redistribute and change under these terms.</p>
0640 
0641 <p>To do so, attach the following notices to the program.  It is safest 
0642 to attach them to the start of each source file to most effectively 
0643 state the exclusion of warranty; and each file should have at least 
0644 the "copyright" line and a pointer to where the full notice is found.</p>
0645 
0646 <pre>    &lt;one line to give the program's name and a brief idea of what it does.&gt;
0647     Copyright (C) &lt;year&gt;  &lt;name of author&gt;
0648 
0649     This program is free software: you can redistribute it and/or modify
0650     it under the terms of the GNU Affero General Public License as
0651     published by the Free Software Foundation, either version 3 of the
0652     License, or (at your option) any later version.
0653 
0654     This program is distributed in the hope that it will be useful,
0655     but WITHOUT ANY WARRANTY; without even the implied warranty of
0656     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
0657     GNU Affero General Public License for more details.
0658 
0659     You should have received a copy of the GNU Affero General Public License
0660     along with this program.  If not, see &lt;https://www.gnu.org/licenses/&gt;.
0661 </pre>
0662 
0663 <p>Also add information on how to contact you by electronic and paper mail.</p>
0664 
0665 <p>If your software can interact with users remotely through a computer 
0666 network, you should also make sure that it provides a way for users to 
0667 get its source.  For example, if your program is a web application, its 
0668 interface could display a "Source" link that leads users to an archive 
0669 of the code.  There are many ways you could offer source, and different 
0670 solutions will be better for different programs; see section 13 for the 
0671 specific requirements.</p>
0672 
0673 <p>You should also get your employer (if you work as a programmer) or school, 
0674 if any, to sign a "copyright disclaimer" for the program, if necessary.
