By contrast, 19 | our General Public Licenses are intended to guarantee your freedom to 20 | share and change all versions of a program--to make sure it remains 21 | free software for all its users. 22 | 23 | When we speak of free software, we are referring to freedom, not 24 | price. Our General Public Licenses are designed to make sure that you 25 | have the freedom to distribute copies of free software (and charge for 26 | them if you wish), that you receive source code or can get it if you 27 | want it, that you can change the software or use pieces of it in new 28 | free programs, and that you know you can do these things. 29 | 30 | Developers that use our General Public Licenses protect your rights 31 | with two steps: (1) assert copyright on the software, and (2) offer 32 | you this License which gives you legal permission to copy, distribute 33 | and/or modify the software. 34 | 35 | A secondary benefit of defending all users' freedom is that 36 | improvements made in alternate versions of the program, if they 37 | receive widespread use, become available for other developers to 38 | incorporate. Many developers of free software are heartened and 39 | encouraged by the resulting cooperation. However, in the case of 40 | software used on network servers, this result may fail to come about. 41 | The GNU General Public License permits making a modified version and 42 | letting the public access it on a server without ever releasing its 43 | source code to the public. 44 | 45 | The GNU Affero General Public License is designed specifically to 46 | ensure that, in such cases, the modified source code becomes available 47 | to the community. It requires the operator of a network server to 48 | provide the source code of the modified version running there to the 49 | users of that server. Therefore, public use of a modified version, on 50 | a publicly accessible server, gives the public access to the source 51 | code of the modified version. 52 | 53 | An older license, called the Affero General Public License and 54 | published by Affero, was designed to accomplish similar goals. This is 55 | a different license, not a version of the Affero GPL, but Affero has 56 | released a new version of the Affero GPL which permits relicensing 57 | under this license. 58 | 59 | The precise terms and conditions for copying, distribution and 60 | modification follow. 61 | 62 | ### TERMS AND CONDITIONS 63 | 64 | #### 0. Definitions. 65 | 66 | "This License" refers to version 3 of the GNU Affero General Public 67 | License. 68 | 69 | "Copyright" also means copyright-like laws that apply to other kinds 70 | of works, such as semiconductor masks. 71 | 72 | "The Program" refers to any copyrightable work licensed under this 73 | License. Each licensee is addressed as "you". "Licensees" and 74 | "recipients" may be individuals or organizations. 75 | 76 | To "modify" a work means to copy from or adapt all or part of the work 77 | in a fashion requiring copyright permission, other than the making of 78 | an exact copy. The resulting work is called a "modified version" of 79 | the earlier work or a work "based on" the earlier work. 80 | 81 | A "covered work" means either the unmodified Program or a work based 82 | on the Program. 83 | 84 | To "propagate" a work means to do anything with it that, without 85 | permission, would make you directly or secondarily liable for 86 | infringement under applicable copyright law, except executing it on a 87 | computer or modifying a private copy. Propagation includes copying, 88 | distribution (with or without modification), making available to the 89 | public, and in some countries other activities as well. 90 | 91 | To "convey" a work means any kind of propagation that enables other 92 | parties to make or receive copies. Mere interaction with a user 93 | through a computer network, with no transfer of a copy, is not 94 | conveying. 95 | 96 | An interactive user interface displays "Appropriate Legal Notices" to 97 | the extent that it includes a convenient and prominently visible 98 | feature that (1) displays an appropriate copyright notice, and (2) 99 | tells the user that there is no warranty for the work (except to the 100 | extent that warranties are provided), that licensees may convey the 101 | work under this License, and how to view a copy of this License. If 102 | the interface presents a list of user commands or options, such as a 103 | menu, a prominent item in the list meets this criterion. 104 | 105 | #### 1. Source Code. 106 | 107 | The "source code" for a work means the preferred form of the work for 108 | making modifications to it. "Object code" means any non-source form of 109 | a work. 110 | 111 | A "Standard Interface" means an interface that either is an official 112 | standard defined by a recognized standards body, or, in the case of 113 | interfaces specified for a particular programming language, one that 114 | is widely used among developers working in that language. 115 | 116 | The "System Libraries" of an executable work include anything, other 117 | than the work as a whole, that (a) is included in the normal form of 118 | packaging a Major Component, but which is not part of that Major 119 | Component, and (b) serves only to enable use of the work with that 120 | Major Component, or to implement a Standard Interface for which an 121 | implementation is available to the public in source code form. A 122 | "Major Component", in this context, means a major essential component 123 | (kernel, window system, and so on) of the specific operating system 124 | (if any) on which the executable work runs, or a compiler used to 125 | produce the work, or an object code interpreter used to run it. 126 | 127 | The "Corresponding Source" for a work in object code form means all 128 | the source code needed to generate, install, and (for an executable 129 | work) run the object code and to modify the work, including scripts to 130 | control those activities. However, it does not include the work's 131 | System Libraries, or general-purpose tools or generally available free 132 | programs which are used unmodified in performing those activities but 133 | which are not part of the work. For example, Corresponding Source 134 | includes interface definition files associated with source files for 135 | the work, and the source code for shared libraries and dynamically 136 | linked subprograms that the work is specifically designed to require, 137 | such as by intimate data communication or control flow between those 138 | subprograms and other parts of the work. 139 | 140 | The Corresponding Source need not include anything that users can 141 | regenerate automatically from other parts of the Corresponding Source. 142 | 143 | The Corresponding Source for a work in source code form is that same 144 | work. 145 | 146 | #### 2. Basic Permissions. 147 | 148 | All rights granted under this License are granted for the term of 149 | copyright on the Program, and are irrevocable provided the stated 150 | conditions are met. This License explicitly affirms your unlimited 151 | permission to run the unmodified Program. The output from running a 152 | covered work is covered by this License only if the output, given its 153 | content, constitutes a covered work. This License acknowledges your 154 | rights of fair use or other equivalent, as provided by copyright law. 155 | 156 | You may make, run and propagate covered works that you do not convey, 157 | without conditions so long as your license otherwise remains in force. 158 | You may convey covered works to others for the sole purpose of having 159 | them make modifications exclusively for you, or provide you with 160 | facilities for running those works, provided that you comply with the 161 | terms of this License in conveying all material for which you do not 162 | control copyright. Those thus making or running the covered works for 163 | you must do so exclusively on your behalf, under your direction and 164 | control, on terms that prohibit them from making any copies of your 165 | copyrighted material outside their relationship with you. 166 | 167 | Conveying under any other circumstances is permitted solely under the 168 | conditions stated below. Sublicensing is not allowed; section 10 makes 169 | it unnecessary. 170 | 171 | #### 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 172 | 173 | No covered work shall be deemed part of an effective technological 174 | measure under any applicable law fulfilling obligations under article 175 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or 176 | similar laws prohibiting or restricting circumvention of such 177 | measures. 178 | 179 | When you convey a covered work, you waive any legal power to forbid 180 | circumvention of technological measures to the extent such 181 | circumvention is effected by exercising rights under this License with 182 | respect to the covered work, and you disclaim any intention to limit 183 | operation or modification of the work as a means of enforcing, against 184 | the work's users, your or third parties' legal rights to forbid 185 | circumvention of technological measures. 186 | 187 | #### 4. Conveying Verbatim Copies. 188 | 189 | You may convey verbatim copies of the Program's source code as you 190 | receive it, in any medium, provided that you conspicuously and 191 | appropriately publish on each copy an appropriate copyright notice; 192 | keep intact all notices stating that this License and any 193 | non-permissive terms added in accord with section 7 apply to the code; 194 | keep intact all notices of the absence of any warranty; and give all 195 | recipients a copy of this License along with the Program. 196 | 197 | You may charge any price or no price for each copy that you convey, 198 | and you may offer support or warranty protection for a fee. 199 | 200 | #### 5. Conveying Modified Source Versions. 201 | 202 | You may convey a work based on the Program, or the modifications to 203 | produce it from the Program, in the form of source code under the 204 | terms of section 4, provided that you also meet all of these 205 | conditions: 206 | 207 | - a) The work must carry prominent notices stating that you modified 208 | it, and giving a relevant date. 209 | - b) The work must carry prominent notices stating that it is 210 | released under this License and any conditions added under 211 | section 7. This requirement modifies the requirement in section 4 212 | to "keep intact all notices". 213 | - c) You must license the entire work, as a whole, under this 214 | License to anyone who comes into possession of a copy. This 215 | License will therefore apply, along with any applicable section 7 216 | additional terms, to the whole of the work, and all its parts, 217 | regardless of how they are packaged. This License gives no 218 | permission to license the work in any other way, but it does not 219 | invalidate such permission if you have separately received it. 220 | - d) If the work has interactive user interfaces, each must display 221 | Appropriate Legal Notices; however, if the Program has interactive 222 | interfaces that do not display Appropriate Legal Notices, your 223 | work need not make them do so. 224 | 225 | A compilation of a covered work with other separate and independent 226 | works, which are not by their nature extensions of the covered work, 227 | and which are not combined with it such as to form a larger program, 228 | in or on a volume of a storage or distribution medium, is called an 229 | "aggregate" if the compilation and its resulting copyright are not 230 | used to limit the access or legal rights of the compilation's users 231 | beyond what the individual works permit. Inclusion of a covered work 232 | in an aggregate does not cause this License to apply to the other 233 | parts of the aggregate. 234 | 235 | #### 6. Conveying Non-Source Forms. 236 | 237 | You may convey a covered work in object code form under the terms of 238 | sections 4 and 5, provided that you also convey the machine-readable 239 | Corresponding Source under the terms of this License, in one of these 240 | ways: 241 | 242 | - a) Convey the object code in, or embodied in, a physical product 243 | (including a physical distribution medium), accompanied by the 244 | Corresponding Source fixed on a durable physical medium 245 | customarily used for software interchange. 246 | - b) Convey the object code in, or embodied in, a physical product 247 | (including a physical distribution medium), accompanied by a 248 | written offer, valid for at least three years and valid for as 249 | long as you offer spare parts or customer support for that product 250 | model, to give anyone who possesses the object code either (1) a 251 | copy of the Corresponding Source for all the software in the 252 | product that is covered by this License, on a durable physical 253 | medium customarily used for software interchange, for a price no 254 | more than your reasonable cost of physically performing this 255 | conveying of source, or (2) access to copy the Corresponding 256 | Source from a network server at no charge. 257 | - c) Convey individual copies of the object code with a copy of the 258 | written offer to provide the Corresponding Source. This 259 | alternative is allowed only occasionally and noncommercially, and 260 | only if you received the object code with such an offer, in accord 261 | with subsection 6b. 262 | - d) Convey the object code by offering access from a designated 263 | place (gratis or for a charge), and offer equivalent access to the 264 | Corresponding Source in the same way through the same place at no 265 | further charge. You need not require recipients to copy the 266 | Corresponding Source along with the object code. If the place to 267 | copy the object code is a network server, the Corresponding Source 268 | may be on a different server (operated by you or a third party) 269 | that supports equivalent copying facilities, provided you maintain 270 | clear directions next to the object code saying where to find the 271 | Corresponding Source. Regardless of what server hosts the 272 | Corresponding Source, you remain obligated to ensure that it is 273 | available for as long as needed to satisfy these requirements. 274 | - e) Convey the object code using peer-to-peer transmission, 275 | provided you inform other peers where the object code and 276 | Corresponding Source of the work are being offered to the general 277 | public at no charge under subsection 6d. 278 | 279 | A separable portion of the object code, whose source code is excluded 280 | from the Corresponding Source as a System Library, need not be 281 | included in conveying the object code work. 282 | 283 | A "User Product" is either (1) a "consumer product", which means any 284 | tangible personal property which is normally used for personal, 285 | family, or household purposes, or (2) anything designed or sold for 286 | incorporation into a dwelling. In determining whether a product is a 287 | consumer product, doubtful cases shall be resolved in favor of 288 | coverage. For a particular product received by a particular user, 289 | "normally used" refers to a typical or common use of that class of 290 | product, regardless of the status of the particular user or of the way 291 | in which the particular user actually uses, or expects or is expected 292 | to use, the product. A product is a consumer product regardless of 293 | whether the product has substantial commercial, industrial or 294 | non-consumer uses, unless such uses represent the only significant 295 | mode of use of the product. 296 | 297 | "Installation Information" for a User Product means any methods, 298 | procedures, authorization keys, or other information required to 299 | install and execute modified versions of a covered work in that User 300 | Product from a modified version of its Corresponding Source. The 301 | information must suffice to ensure that the continued functioning of 302 | the modified object code is in no case prevented or interfered with 303 | solely because modification has been made. 304 | 305 | If you convey an object code work under this section in, or with, or 306 | specifically for use in, a User Product, and the conveying occurs as 307 | part of a transaction in which the right of possession and use of the 308 | User Product is transferred to the recipient in perpetuity or for a 309 | fixed term (regardless of how the transaction is characterized), the 310 | Corresponding Source conveyed under this section must be accompanied 311 | by the Installation Information. But this requirement does not apply 312 | if neither you nor any third party retains the ability to install 313 | modified object code on the User Product (for example, the work has 314 | been installed in ROM). 315 | 316 | The requirement to provide Installation Information does not include a 317 | requirement to continue to provide support service, warranty, or 318 | updates for a work that has been modified or installed by the 319 | recipient, or for the User Product in which it has been modified or 320 | installed. Access to a network may be denied when the modification 321 | itself materially and adversely affects the operation of the network 322 | or violates the rules and protocols for communication across the 323 | network. 324 | 325 | Corresponding Source conveyed, and Installation Information provided, 326 | in accord with this section must be in a format that is publicly 327 | documented (and with an implementation available to the public in 328 | source code form), and must require no special password or key for 329 | unpacking, reading or copying. 330 | 331 | #### 7. Additional Terms. 332 | 333 | "Additional permissions" are terms that supplement the terms of this 334 | License by making exceptions from one or more of its conditions. 335 | Additional permissions that are applicable to the entire Program shall 336 | be treated as though they were included in this License, to the extent 337 | that they are valid under applicable law. If additional permissions 338 | apply only to part of the Program, that part may be used separately 339 | under those permissions, but the entire Program remains governed by 340 | this License without regard to the additional permissions. 341 | 342 | When you convey a copy of a covered work, you may at your option 343 | remove any additional permissions from that copy, or from any part of 344 | it. (Additional permissions may be written to require their own 345 | removal in certain cases when you modify the work.) You may place 346 | additional permissions on material, added by you to a covered work, 347 | for which you have or can give appropriate copyright permission. 348 | 349 | Notwithstanding any other provision of this License, for material you 350 | add to a covered work, you may (if authorized by the copyright holders 351 | of that material) supplement the terms of this License with terms: 352 | 353 | - a) Disclaiming warranty or limiting liability differently from the 354 | terms of sections 15 and 16 of this License; or 355 | - b) Requiring preservation of specified reasonable legal notices or 356 | author attributions in that material or in the Appropriate Legal 357 | Notices displayed by works containing it; or 358 | - c) Prohibiting misrepresentation of the origin of that material, 359 | or requiring that modified versions of such material be marked in 360 | reasonable ways as different from the original version; or 361 | - d) Limiting the use for publicity purposes of names of licensors 362 | or authors of the material; or 363 | - e) Declining to grant rights under trademark law for use of some 364 | trade names, trademarks, or service marks; or 365 | - f) Requiring indemnification of licensors and authors of that 366 | material by anyone who conveys the material (or modified versions 367 | of it) with contractual assumptions of liability to the recipient, 368 | for any liability that these contractual assumptions directly 369 | impose on those licensors and authors. 370 | 371 | All other non-permissive additional terms are considered "further 372 | restrictions" within the meaning of section 10. If the Program as you 373 | received it, or any part of it, contains a notice stating that it is 374 | governed by this License along with a term that is a further 375 | restriction, you may remove that term. If a license document contains 376 | a further restriction but permits relicensing or conveying under this 377 | License, you may add to a covered work material governed by the terms 378 | of that license document, provided that the further restriction does 379 | not survive such relicensing or conveying. 380 | 381 | If you add terms to a covered work in accord with this section, you 382 | must place, in the relevant source files, a statement of the 383 | additional terms that apply to those files, or a notice indicating 384 | where to find the applicable terms. 385 | 386 | Additional terms, permissive or non-permissive, may be stated in the 387 | form of a separately written license, or stated as exceptions; the 388 | above requirements apply either way. 389 | 390 | #### 8. Termination. 391 | 392 | You may not propagate or modify a covered work except as expressly 393 | provided under this License. Any attempt otherwise to propagate or 394 | modify it is void, and will automatically terminate your rights under 395 | this License (including any patent licenses granted under the third 396 | paragraph of section 11). 397 | 398 | However, if you cease all violation of this License, then your license 399 | from a particular copyright holder is reinstated (a) provisionally, 400 | unless and until the copyright holder explicitly and finally 401 | terminates your license, and (b) permanently, if the copyright holder 402 | fails to notify you of the violation by some reasonable means prior to 403 | 60 days after the cessation. 404 | 405 | Moreover, your license from a particular copyright holder is 406 | reinstated permanently if the copyright holder notifies you of the 407 | violation by some reasonable means, this is the first time you have 408 | received notice of violation of this License (for any work) from that 409 | copyright holder, and you cure the violation prior to 30 days after 410 | your receipt of the notice. 411 | 412 | Termination of your rights under this section does not terminate the 413 | licenses of parties who have received copies or rights from you under 414 | this License. If your rights have been terminated and not permanently 415 | reinstated, you do not qualify to receive new licenses for the same 416 | material under section 10. 417 | 418 | #### 9. Acceptance Not Required for Having Copies. 419 | 420 | You are not required to accept this License in order to receive or run 421 | a copy of the Program. Ancillary propagation of a covered work 422 | occurring solely as a consequence of using peer-to-peer transmission 423 | to receive a copy likewise does not require acceptance. However, 424 | nothing other than this License grants you permission to propagate or 425 | modify any covered work. These actions infringe copyright if you do 426 | not accept this License. Therefore, by modifying or propagating a 427 | covered work, you indicate your acceptance of this License to do so. 428 | 429 | #### 10. Automatic Licensing of Downstream Recipients. 430 | 431 | Each time you convey a covered work, the recipient automatically 432 | receives a license from the original licensors, to run, modify and 433 | propagate that work, subject to this License. You are not responsible 434 | for enforcing compliance by third parties with this License. 435 | 436 | An "entity transaction" is a transaction transferring control of an 437 | organization, or substantially all assets of one, or subdividing an 438 | organization, or merging organizations. If propagation of a covered 439 | work results from an entity transaction, each party to that 440 | transaction who receives a copy of the work also receives whatever 441 | licenses to the work the party's predecessor in interest had or could 442 | give under the previous paragraph, plus a right to possession of the 443 | Corresponding Source of the work from the predecessor in interest, if 444 | the predecessor has it or can get it with reasonable efforts. 445 | 446 | You may not impose any further restrictions on the exercise of the 447 | rights granted or affirmed under this License. For example, you may 448 | not impose a license fee, royalty, or other charge for exercise of 449 | rights granted under this License, and you may not initiate litigation 450 | (including a cross-claim or counterclaim in a lawsuit) alleging that 451 | any patent claim is infringed by making, using, selling, offering for 452 | sale, or importing the Program or any portion of it. 453 | 454 | #### 11. Patents. 455 | 456 | A "contributor" is a copyright holder who authorizes use under this 457 | License of the Program or a work on which the Program is based. The 458 | work thus licensed is called the contributor's "contributor version". 459 | 460 | A contributor's "essential patent claims" are all patent claims owned 461 | or controlled by the contributor, whether already acquired or 462 | hereafter acquired, that would be infringed by some manner, permitted 463 | by this License, of making, using, or selling its contributor version, 464 | but do not include claims that would be infringed only as a 465 | consequence of further modification of the contributor version. For 466 | purposes of this definition, "control" includes the right to grant 467 | patent sublicenses in a manner consistent with the requirements of 468 | this License. 469 | 470 | Each contributor grants you a non-exclusive, worldwide, royalty-free 471 | patent license under the contributor's essential patent claims, to 472 | make, use, sell, offer for sale, import and otherwise run, modify and 473 | propagate the contents of its contributor version. 474 | 475 | In the following three paragraphs, a "patent license" is any express 476 | agreement or commitment, however denominated, not to enforce a patent 477 | (such as an express permission to practice a patent or covenant not to 478 | sue for patent infringement). To "grant" such a patent license to a 479 | party means to make such an agreement or commitment not to enforce a 480 | patent against the party. 481 | 482 | If you convey a covered work, knowingly relying on a patent license, 483 | and the Corresponding Source of the work is not available for anyone 484 | to copy, free of charge and under the terms of this License, through a 485 | publicly available network server or other readily accessible means, 486 | then you must either (1) cause the Corresponding Source to be so 487 | available, or (2) arrange to deprive yourself of the benefit of the 488 | patent license for this particular work, or (3) arrange, in a manner 489 | consistent with the requirements of this License, to extend the patent 490 | license to downstream recipients. "Knowingly relying" means you have 491 | actual knowledge that, but for the patent license, your conveying the 492 | covered work in a country, or your recipient's use of the covered work 493 | in a country, would infringe one or more identifiable patents in that 494 | country that you have reason to believe are valid. 495 | 496 | If, pursuant to or in connection with a single transaction or 497 | arrangement, you convey, or propagate by procuring conveyance of, a 498 | covered work, and grant a patent license to some of the parties 499 | receiving the covered work authorizing them to use, propagate, modify 500 | or convey a specific copy of the covered work, then the patent license 501 | you grant is automatically extended to all recipients of the covered 502 | work and works based on it. 503 | 504 | A patent license is "discriminatory" if it does not include within the 505 | scope of its coverage, prohibits the exercise of, or is conditioned on 506 | the non-exercise of one or more of the rights that are specifically 507 | granted under this License. You may not convey a covered work if you 508 | are a party to an arrangement with a third party that is in the 509 | business of distributing software, under which you make payment to the 510 | third party based on the extent of your activity of conveying the 511 | work, and under which the third party grants, to any of the parties 512 | who would receive the covered work from you, a discriminatory patent 513 | license (a) in connection with copies of the covered work conveyed by 514 | you (or copies made from those copies), or (b) primarily for and in 515 | connection with specific products or compilations that contain the 516 | covered work, unless you entered into that arrangement, or that patent 517 | license was granted, prior to 28 March 2007. 518 | 519 | Nothing in this License shall be construed as excluding or limiting 520 | any implied license or other defenses to infringement that may 521 | otherwise be available to you under applicable patent law. 522 | 523 | #### 12. No Surrender of Others' Freedom. 524 | 525 | If conditions are imposed on you (whether by court order, agreement or 526 | otherwise) that contradict the conditions of this License, they do not 527 | excuse you from the conditions of this License. If you cannot convey a 528 | covered work so as to satisfy simultaneously your obligations under 529 | this License and any other pertinent obligations, then as a 530 | consequence you may not convey it at all. For example, if you agree to 531 | terms that obligate you to collect a royalty for further conveying 532 | from those to whom you convey the Program, the only way you could 533 | satisfy both those terms and this License would be to refrain entirely 534 | from conveying the Program. 535 | 536 | #### 13. Remote Network Interaction; Use with the GNU General Public License. 537 | 538 | Notwithstanding any other provision of this License, if you modify the 539 | Program, your modified version must prominently offer all users 540 | interacting with it remotely through a computer network (if your 541 | version supports such interaction) an opportunity to receive the 542 | Corresponding Source of your version by providing access to the 543 | Corresponding Source from a network server at no charge, through some 544 | standard or customary means of facilitating copying of software. This 545 | Corresponding Source shall include the Corresponding Source for any 546 | work covered by version 3 of the GNU General Public License that is 547 | incorporated pursuant to the following paragraph. 548 | 549 | Notwithstanding any other provision of this License, you have 550 | permission to link or combine any covered work with a work licensed 551 | under version 3 of the GNU General Public License into a single 552 | combined work, and to convey the resulting work. The terms of this 553 | License will continue to apply to the part which is the covered work, 554 | but the work with which it is combined will remain governed by version 555 | 3 of the GNU General Public License. 556 | 557 | #### 14. Revised Versions of this License. 558 | 559 | The Free Software Foundation may publish revised and/or new versions 560 | of the GNU Affero General Public License from time to time. Such new 561 | versions will be similar in spirit to the present version, but may 562 | differ in detail to address new problems or concerns. 563 | 564 | Each version is given a distinguishing version number. If the Program 565 | specifies that a certain numbered version of the GNU Affero General 566 | Public License "or any later version" applies to it, you have the 567 | option of following the terms and conditions either of that numbered 568 | version or of any later version published by the Free Software 569 | Foundation. If the Program does not specify a version number of the 570 | GNU Affero General Public License, you may choose any version ever 571 | published by the Free Software Foundation. 572 | 573 | If the Program specifies that a proxy can decide which future versions 574 | of the GNU Affero General Public License can be used, that proxy's 575 | public statement of acceptance of a version permanently authorizes you 576 | to choose that version for the Program. 577 | 578 | Later license versions may give you additional or different 579 | permissions. However, no additional obligations are imposed on any 580 | author or copyright holder as a result of your choosing to follow a 581 | later version. 582 | 583 | #### 15. Disclaimer of Warranty. 584 | 585 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 586 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 587 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT 588 | WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT 589 | LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR 590 | A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND 591 | PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE 592 | DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR 593 | CORRECTION. 594 | 595 | #### 16. Limitation of Liability. 596 | 597 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 598 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR 599 | CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, 600 | INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES 601 | ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT 602 | NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR 603 | LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM 604 | TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER 605 | PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 606 | 607 | #### 17. Interpretation of Sections 15 and 16. 608 | 609 | If the disclaimer of warranty and limitation of liability provided 610 | above cannot be given local legal effect according to their terms, 611 | reviewing courts shall apply local law that most closely approximates 612 | an absolute waiver of all civil liability in connection with the 613 | Program, unless a warranty or assumption of liability accompanies a 614 | copy of the Program in return for a fee. 615 | 616 | END OF TERMS AND CONDITIONS 617 | 618 | ### How to Apply These Terms to Your New Programs 619 | 620 | If you develop a new program, and you want it to be of the greatest 621 | possible use to the public, the best way to achieve this is to make it 622 | free software which everyone can redistribute and change under these 623 | terms. 624 | 625 | To do so, attach the following notices to the program. It is safest to 626 | attach them to the start of each source file to most effectively state 627 | the exclusion of warranty; and each file should have at least the 628 | "copyright" line and a pointer to where the full notice is found. 629 | 630 | 631 | Copyright (C) 632 | 633 | This program is free software: you can redistribute it and/or modify 634 | it under the terms of the GNU Affero General Public License as 635 | published by the Free Software Foundation, either version 3 of the 636 | License, or (at your option) any later version. 637 | 638 | This program is distributed in the hope that it will be useful, 639 | but WITHOUT ANY WARRANTY; without even the implied warranty of 640 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 641 | GNU Affero General Public License for more details. 642 | 643 | You should have received a copy of the GNU Affero General Public License 644 | along with this program. If not, see . 645 | 646 | Also add information on how to contact you by electronic and paper 647 | mail. 648 | 649 | If your software can interact with users remotely through a computer 650 | network, you should also make sure that it provides a way for users to 651 | get its source. For example, if your program is a web application, its 652 | interface could display a "Source" link that leads users to an archive 653 | of the code. There are many ways you could offer source, and different 654 | solutions will be better for different programs; see section 13 for 655 | the specific requirements. 656 | 657 | You should also get your employer (if you work as a programmer) or 658 | school, if any, to sign a "copyright disclaimer" for the program, if 659 | necessary. For more information on this, and how to apply and follow 660 | the GNU AGPL, see . 661 | --------------------------------------------------------------------------------
