1 This software is 2 3 © 2013-15 Christoph Lohmann <firstname.lastname@example.org> 4 5 See the following part of this file for the license details: 6 7 8 GNU AFFERO GENERAL PUBLIC LICENSE 9 Version 3, 19 November 2007 10 11 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> 12 Everyone is permitted to copy and distribute verbatim copies 13 of this license document, but changing it is not allowed. 14 15 Preamble 16 17 The GNU Affero General Public License is a free, copyleft license for 18 software and other kinds of works, specifically designed to ensure 19 cooperation with the community in the case of network server software. 20 21 The licenses for most software and other practical works are designed 22 to take away your freedom to share and change the works. By contrast, 23 our General Public Licenses are intended to guarantee your freedom to 24 share and change all versions of a program--to make sure it remains free 25 software for all its users. 26 27 When we speak of free software, we are referring to freedom, not 28 price. Our General Public Licenses are designed to make sure that you 29 have the freedom to distribute copies of free software (and charge for 30 them if you wish), that you receive source code or can get it if you 31 want it, that you can change the software or use pieces of it in new 32 free programs, and that you know you can do these things. 33 34 Developers that use our General Public Licenses protect your rights 35 with two steps: (1) assert copyright on the software, and (2) offer 36 you this License which gives you legal permission to copy, distribute 37 and/or modify the software. 38 39 A secondary benefit of defending all users' freedom is that 40 improvements made in alternate versions of the program, if they 41 receive widespread use, become available for other developers to 42 incorporate. Many developers of free software are heartened and 43 encouraged by the resulting cooperation. However, in the case of 44 software used on network servers, this result may fail to come about. 45 The GNU General Public License permits making a modified version and 46 letting the public access it on a server without ever releasing its 47 source code to the public. 48 49 The GNU Affero General Public License is designed specifically to 50 ensure that, in such cases, the modified source code becomes available 51 to the community. It requires the operator of a network server to 52 provide the source code of the modified version running there to the 53 users of that server. Therefore, public use of a modified version, on 54 a publicly accessible server, gives the public access to the source 55 code of the modified version. 56 57 An older license, called the Affero General Public License and 58 published by Affero, was designed to accomplish similar goals. This is 59 a different license, not a version of the Affero GPL, but Affero has 60 released a new version of the Affero GPL which permits relicensing under 61 this license. 62 63 The precise terms and conditions for copying, distribution and 64 modification follow. 65 66 TERMS AND CONDITIONS 67 68 0. Definitions. 69 70 "This License" refers to version 3 of the GNU Affero General Public License. 71 72 "Copyright" also means copyright-like laws that apply to other kinds of 73 works, such as semiconductor masks. 74 75 "The Program" refers to any copyrightable work licensed under this 76 License. Each licensee is addressed as "you". "Licensees" and 77 "recipients" may be individuals or organizations. 78 79 To "modify" a work means to copy from or adapt all or part of the work 80 in a fashion requiring copyright permission, other than the making of an 81 exact copy. The resulting work is called a "modified version" of the 82 earlier work or a work "based on" the earlier work. 83 84 A "covered work" means either the unmodified Program or a work based 85 on the Program. 86 87 To "propagate" a work means to do anything with it that, without 88 permission, would make you directly or secondarily liable for 89 infringement under applicable copyright law, except executing it on a 90 computer or modifying a private copy. Propagation includes copying, 91 distribution (with or without modification), making available to the 92 public, and in some countries other activities as well. 93 94 To "convey" a work means any kind of propagation that enables other 95 parties to make or receive copies. Mere interaction with a user through 96 a computer network, with no transfer of a copy, is not conveying. 97 98 An interactive user interface displays "Appropriate Legal Notices" 99 to the extent that it includes a convenient and prominently visible 100 feature that (1) displays an appropriate copyright notice, and (2) 101 tells the user that there is no warranty for the work (except to the 102 extent that warranties are provided), that licensees may convey the 103 work under this License, and how to view a copy of this License. If 104 the interface presents a list of user commands or options, such as a 105 menu, a prominent item in the list meets this criterion. 106 107 1. Source Code. 108 109 The "source code" for a work means the preferred form of the work 110 for making modifications to it. "Object code" means any non-source 111 form of a work. 112 113 A "Standard Interface" means an interface that either is an official 114 standard defined by a recognized standards body, or, in the case of 115 interfaces specified for a particular programming language, one that 116 is widely used among developers working in that language. 117 118 The "System Libraries" of an executable work include anything, other 119 than the work as a whole, that (a) is included in the normal form of 120 packaging a Major Component, but which is not part of that Major 121 Component, and (b) serves only to enable use of the work with that 122 Major Component, or to implement a Standard Interface for which an 123 implementation is available to the public in source code form. A 124 "Major Component", in this context, means a major essential component 125 (kernel, window system, and so on) of the specific operating system 126 (if any) on which the executable work runs, or a compiler used to 127 produce the work, or an object code interpreter used to run it. 128 129 The "Corresponding Source" for a work in object code form means all 130 the source code needed to generate, install, and (for an executable 131 work) run the object code and to modify the work, including scripts to 132 control those activities. However, it does not include the work's 133 System Libraries, or general-purpose tools or generally available free 134 programs which are used unmodified in performing those activities but 135 which are not part of the work. For example, Corresponding Source 136 includes interface definition files associated with source files for 137 the work, and the source code for shared libraries and dynamically 138 linked subprograms that the work is specifically designed to require, 139 such as by intimate data communication or control flow between those 140 subprograms and other parts of the work. 141 142 The Corresponding Source need not include anything that users 143 can regenerate automatically from other parts of the Corresponding 144 Source. 145 146 The Corresponding Source for a work in source code form is that 147 same work. 148 149 2. Basic Permissions. 150 151 All rights granted under this License are granted for the term of 152 copyright on the Program, and are irrevocable provided the stated 153 conditions are met. This License explicitly affirms your unlimited 154 permission to run the unmodified Program. The output from running a 155 covered work is covered by this License only if the output, given its 156 content, constitutes a covered work. This License acknowledges your 157 rights of fair use or other equivalent, as provided by copyright law. 158 159 You may make, run and propagate covered works that you do not 160 convey, without conditions so long as your license otherwise remains 161 in force. You may convey covered works to others for the sole purpose 162 of having them make modifications exclusively for you, or provide you 163 with facilities for running those works, provided that you comply with 164 the terms of this License in conveying all material for which you do 165 not control copyright. Those thus making or running the covered works 166 for you must do so exclusively on your behalf, under your direction 167 and control, on terms that prohibit them from making any copies of 168 your copyrighted material outside their relationship with you. 169 170 Conveying under any other circumstances is permitted solely under 171 the conditions stated below. Sublicensing is not allowed; section 10 172 makes it unnecessary. 173 174 3. Protecting Users' Legal Rights From Anti-Circumvention Law. 175 176 No covered work shall be deemed part of an effective technological 177 measure under any applicable law fulfilling obligations under article 178 11 of the WIPO copyright treaty adopted on 20 December 1996, or 179 similar laws prohibiting or restricting circumvention of such 180 measures. 181 182 When you convey a covered work, you waive any legal power to forbid 183 circumvention of technological measures to the extent such circumvention 184 is effected by exercising rights under this License with respect to 185 the covered work, and you disclaim any intention to limit operation or 186 modification of the work as a means of enforcing, against the work's 187 users, your or third parties' legal rights to forbid circumvention of 188 technological measures. 189 190 4. Conveying Verbatim Copies. 191 192 You may convey verbatim copies of the Program's source code as you 193 receive it, in any medium, provided that you conspicuously and 194 appropriately publish on each copy an appropriate copyright notice; 195 keep intact all notices stating that this License and any 196 non-permissive terms added in accord with section 7 apply to the code; 197 keep intact all notices of the absence of any warranty; and give all 198 recipients a copy of this License along with the Program. 199 200 You may charge any price or no price for each copy that you convey, 201 and you may offer support or warranty protection for a fee. 202 203 5. Conveying Modified Source Versions. 204 205 You may convey a work based on the Program, or the modifications to 206 produce it from the Program, in the form of source code under the 207 terms of section 4, provided that you also meet all of these conditions: 208 209 a) The work must carry prominent notices stating that you modified 210 it, and giving a relevant date. 211 212 b) The work must carry prominent notices stating that it is 213 released under this License and any conditions added under section 214 7. This requirement modifies the requirement in section 4 to 215 "keep intact all notices". 216 217 c) You must license the entire work, as a whole, under this 218 License to anyone who comes into possession of a copy. This 219 License will therefore apply, along with any applicable section 7 220 additional terms, to the whole of the work, and all its parts, 221 regardless of how they are packaged. This License gives no 222 permission to license the work in any other way, but it does not 223 invalidate such permission if you have separately received it. 224 225 d) If the work has interactive user interfaces, each must display 226 Appropriate Legal Notices; however, if the Program has interactive 227 interfaces that do not display Appropriate Legal Notices, your 228 work need not make them do so. 229 230 A compilation of a covered work with other separate and independent 231 works, which are not by their nature extensions of the covered work, 232 and which are not combined with it such as to form a larger program, 233 in or on a volume of a storage or distribution medium, is called an 234 "aggregate" if the compilation and its resulting copyright are not 235 used to limit the access or legal rights of the compilation's users 236 beyond what the individual works permit. Inclusion of a covered work 237 in an aggregate does not cause this License to apply to the other 238 parts of the aggregate. 239 240 6. Conveying Non-Source Forms. 241 242 You may convey a covered work in object code form under the terms 243 of sections 4 and 5, provided that you also convey the 244 machine-readable Corresponding Source under the terms of this License, 245 in one of these ways: 246 247 a) Convey the object code in, or embodied in, a physical product 248 (including a physical distribution medium), accompanied by the 249 Corresponding Source fixed on a durable physical medium 250 customarily used for software interchange. 251 252 b) Convey the object code in, or embodied in, a physical product 253 (including a physical distribution medium), accompanied by a 254 written offer, valid for at least three years and valid for as 255 long as you offer spare parts or customer support for that product 256 model, to give anyone who possesses the object code either (1) a 257 copy of the Corresponding Source for all the software in the 258 product that is covered by this License, on a durable physical 259 medium customarily used for software interchange, for a price no 260 more than your reasonable cost of physically performing this 261 conveying of source, or (2) access to copy the 262 Corresponding Source from a network server at no charge. 263 264 c) Convey individual copies of the object code with a copy of the 265 written offer to provide the Corresponding Source. This 266 alternative is allowed only occasionally and noncommercially, and 267 only if you received the object code with such an offer, in accord 268 with subsection 6b. 269 270 d) Convey the object code by offering access from a designated 271 place (gratis or for a charge), and offer equivalent access to the 272 Corresponding Source in the same way through the same place at no 273 further charge. You need not require recipients to copy the 274 Corresponding Source along with the object code. If the place to 275 copy the object code is a network server, the Corresponding Source 276 may be on a different server (operated by you or a third party) 277 that supports equivalent copying facilities, provided you maintain 278 clear directions next to the object code saying where to find the 279 Corresponding Source. Regardless of what server hosts the 280 Corresponding Source, you remain obligated to ensure that it is 281 available for as long as needed to satisfy these requirements. 282 283 e) Convey the object code using peer-to-peer transmission, provided 284 you inform other peers where the object code and Corresponding 285 Source of the work are being offered to the general public at no 286 charge under subsection 6d. 287 288 A separable portion of the object code, whose source code is excluded 289 from the Corresponding Source as a System Library, need not be 290 included in conveying the object code work. 291 292 A "User Product" is either (1) a "consumer product", which means any 293 tangible personal property which is normally used for personal, family, 294 or household purposes, or (2) anything designed or sold for incorporation 295 into a dwelling. In determining whether a product is a consumer product, 296 doubtful cases shall be resolved in favor of coverage. For a particular 297 product received by a particular user, "normally used" refers to a 298 typical or common use of that class of product, regardless of the status 299 of the particular user or of the way in which the particular user 300 actually uses, or expects or is expected to use, the product. A product 301 is a consumer product regardless of whether the product has substantial 302 commercial, industrial or non-consumer uses, unless such uses represent 303 the only significant mode of use of the product. 304 305 "Installation Information" for a User Product means any methods, 306 procedures, authorization keys, or other information required to install 307 and execute modified versions of a covered work in that User Product from 308 a modified version of its Corresponding Source. The information must 309 suffice to ensure that the continued functioning of the modified object 310 code is in no case prevented or interfered with solely because 311 modification has been made. 312 313 If you convey an object code work under this section in, or with, or 314 specifically for use in, a User Product, and the conveying occurs as 315 part of a transaction in which the right of possession and use of the 316 User Product is transferred to the recipient in perpetuity or for a 317 fixed term (regardless of how the transaction is characterized), the 318 Corresponding Source conveyed under this section must be accompanied 319 by the Installation Information. But this requirement does not apply 320 if neither you nor any third party retains the ability to install 321 modified object code on the User Product (for example, the work has 322 been installed in ROM). 323 324 The requirement to provide Installation Information does not include a 325 requirement to continue to provide support service, warranty, or updates 326 for a work that has been modified or installed by the recipient, or for 327 the User Product in which it has been modified or installed. Access to a 328 network may be denied when the modification itself materially and 329 adversely affects the operation of the network or violates the rules and 330 protocols for communication across the network. 331 332 Corresponding Source conveyed, and Installation Information provided, 333 in accord with this section must be in a format that is publicly 334 documented (and with an implementation available to the public in 335 source code form), and must require no special password or key for 336 unpacking, reading or copying. 337 338 7. Additional Terms. 339 340 "Additional permissions" are terms that supplement the terms of this 341 License by making exceptions from one or more of its conditions. 342 Additional permissions that are applicable to the entire Program shall 343 be treated as though they were included in this License, to the extent 344 that they are valid under applicable law. If additional permissions 345 apply only to part of the Program, that part may be used separately 346 under those permissions, but the entire Program remains governed by 347 this License without regard to the additional permissions. 348 349 When you convey a copy of a covered work, you may at your option 350 remove any additional permissions from that copy, or from any part of 351 it. (Additional permissions may be written to require their own 352 removal in certain cases when you modify the work.) You may place 353 additional permissions on material, added by you to a covered work, 354 for which you have or can give appropriate copyright permission. 355 356 Notwithstanding any other provision of this License, for material you 357 add to a covered work, you may (if authorized by the copyright holders of 358 that material) supplement the terms of this License with terms: 359 360 a) Disclaiming warranty or limiting liability differently from the 361 terms of sections 15 and 16 of this License; or 362 363 b) Requiring preservation of specified reasonable legal notices or 364 author attributions in that material or in the Appropriate Legal 365 Notices displayed by works containing it; or 366 367 c) Prohibiting misrepresentation of the origin of that material, or 368 requiring that modified versions of such material be marked in 369 reasonable ways as different from the original version; or 370 371 d) Limiting the use for publicity purposes of names of licensors or 372 authors of the material; or 373 374 e) Declining to grant rights under trademark law for use of some 375 trade names, trademarks, or service marks; or 376 377 f) Requiring indemnification of licensors and authors of that 378 material by anyone who conveys the material (or modified versions of 379 it) with contractual assumptions of liability to the recipient, for 380 any liability that these contractual assumptions directly impose on 381 those licensors and authors. 382 383 All other non-permissive additional terms are considered "further 384 restrictions" within the meaning of section 10. If the Program as you 385 received it, or any part of it, contains a notice stating that it is 386 governed by this License along with a term that is a further 387 restriction, you may remove that term. If a license document contains 388 a further restriction but permits relicensing or conveying under this 389 License, you may add to a covered work material governed by the terms 390 of that license document, provided that the further restriction does 391 not survive such relicensing or conveying. 392 393 If you add terms to a covered work in accord with this section, you 394 must place, in the relevant source files, a statement of the 395 additional terms that apply to those files, or a notice indicating 396 where to find the applicable terms. 397 398 Additional terms, permissive or non-permissive, may be stated in the 399 form of a separately written license, or stated as exceptions; 400 the above requirements apply either way. 401 402 8. Termination. 403 404 You may not propagate or modify a covered work except as expressly 405 provided under this License. Any attempt otherwise to propagate or 406 modify it is void, and will automatically terminate your rights under 407 this License (including any patent licenses granted under the third 408 paragraph of section 11). 409 410 However, if you cease all violation of this License, then your 411 license from a particular copyright holder is reinstated (a) 412 provisionally, unless and until the copyright holder explicitly and 413 finally terminates your license, and (b) permanently, if the copyright 414 holder fails to notify you of the violation by some reasonable means 415 prior to 60 days after the cessation. 416 417 Moreover, your license from a particular copyright holder is 418 reinstated permanently if the copyright holder notifies you of the 419 violation by some reasonable means, this is the first time you have 420 received notice of violation of this License (for any work) from that 421 copyright holder, and you cure the violation prior to 30 days after 422 your receipt of the notice. 423 424 Termination of your rights under this section does not terminate the 425 licenses of parties who have received copies or rights from you under 426 this License. If your rights have been terminated and not permanently 427 reinstated, you do not qualify to receive new licenses for the same 428 material under section 10. 429 430 9. Acceptance Not Required for Having Copies. 431 432 You are not required to accept this License in order to receive or 433 run a copy of the Program. Ancillary propagation of a covered work 434 occurring solely as a consequence of using peer-to-peer transmission 435 to receive a copy likewise does not require acceptance. However, 436 nothing other than this License grants you permission to propagate or 437 modify any covered work. These actions infringe copyright if you do 438 not accept this License. Therefore, by modifying or propagating a 439 covered work, you indicate your acceptance of this License to do so. 440 441 10. Automatic Licensing of Downstream Recipients. 442 443 Each time you convey a covered work, the recipient automatically 444 receives a license from the original licensors, to run, modify and 445 propagate that work, subject to this License. You are not responsible 446 for enforcing compliance by third parties with this License. 447 448 An "entity transaction" is a transaction transferring control of an 449 organization, or substantially all assets of one, or subdividing an 450 organization, or merging organizations. If propagation of a covered 451 work results from an entity transaction, each party to that 452 transaction who receives a copy of the work also receives whatever 453 licenses to the work the party's predecessor in interest had or could 454 give under the previous paragraph, plus a right to possession of the 455 Corresponding Source of the work from the predecessor in interest, if 456 the predecessor has it or can get it with reasonable efforts. 457 458 You may not impose any further restrictions on the exercise of the 459 rights granted or affirmed under this License. For example, you may 460 not impose a license fee, royalty, or other charge for exercise of 461 rights granted under this License, and you may not initiate litigation 462 (including a cross-claim or counterclaim in a lawsuit) alleging that 463 any patent claim is infringed by making, using, selling, offering for 464 sale, or importing the Program or any portion of it. 465 466 11. Patents. 467 468 A "contributor" is a copyright holder who authorizes use under this 469 License of the Program or a work on which the Program is based. The 470 work thus licensed is called the contributor's "contributor version". 471 472 A contributor's "essential patent claims" are all patent claims 473 owned or controlled by the contributor, whether already acquired or 474 hereafter acquired, that would be infringed by some manner, permitted 475 by this License, of making, using, or selling its contributor version, 476 but do not include claims that would be infringed only as a 477 consequence of further modification of the contributor version. For 478 purposes of this definition, "control" includes the right to grant 479 patent sublicenses in a manner consistent with the requirements of 480 this License. 481 482 Each contributor grants you a non-exclusive, worldwide, royalty-free 483 patent license under the contributor's essential patent claims, to 484 make, use, sell, offer for sale, import and otherwise run, modify and 485 propagate the contents of its contributor version. 486 487 In the following three paragraphs, a "patent license" is any express 488 agreement or commitment, however denominated, not to enforce a patent 489 (such as an express permission to practice a patent or covenant not to 490 sue for patent infringement). To "grant" such a patent license to a 491 party means to make such an agreement or commitment not to enforce a 492 patent against the party. 493 494 If you convey a covered work, knowingly relying on a patent license, 495 and the Corresponding Source of the work is not available for anyone 496 to copy, free of charge and under the terms of this License, through a 497 publicly available network server or other readily accessible means, 498 then you must either (1) cause the Corresponding Source to be so 499 available, or (2) arrange to deprive yourself of the benefit of the 500 patent license for this particular work, or (3) arrange, in a manner 501 consistent with the requirements of this License, to extend the patent 502 license to downstream recipients. "Knowingly relying" means you have 503 actual knowledge that, but for the patent license, your conveying the 504 covered work in a country, or your recipient's use of the covered work 505 in a country, would infringe one or more identifiable patents in that 506 country that you have reason to believe are valid. 507 508 If, pursuant to or in connection with a single transaction or 509 arrangement, you convey, or propagate by procuring conveyance of, a 510 covered work, and grant a patent license to some of the parties 511 receiving the covered work authorizing them to use, propagate, modify 512 or convey a specific copy of the covered work, then the patent license 513 you grant is automatically extended to all recipients of the covered 514 work and works based on it. 515 516 A patent license is "discriminatory" if it does not include within 517 the scope of its coverage, prohibits the exercise of, or is 518 conditioned on the non-exercise of one or more of the rights that are 519 specifically granted under this License. You may not convey a covered 520 work if you are a party to an arrangement with a third party that is 521 in the business of distributing software, under which you make payment 522 to the third party based on the extent of your activity of conveying 523 the work, and under which the third party grants, to any of the 524 parties who would receive the covered work from you, a discriminatory 525 patent license (a) in connection with copies of the covered work 526 conveyed by you (or copies made from those copies), or (b) primarily 527 for and in connection with specific products or compilations that 528 contain the covered work, unless you entered into that arrangement, 529 or that patent license was granted, prior to 28 March 2007. 530 531 Nothing in this License shall be construed as excluding or limiting 532 any implied license or other defenses to infringement that may 533 otherwise be available to you under applicable patent law. 534 535 12. No Surrender of Others' Freedom. 536 537 If conditions are imposed on you (whether by court order, agreement or 538 otherwise) that contradict the conditions of this License, they do not 539 excuse you from the conditions of this License. If you cannot convey a 540 covered work so as to satisfy simultaneously your obligations under this 541 License and any other pertinent obligations, then as a consequence you may 542 not convey it at all. For example, if you agree to terms that obligate you 543 to collect a royalty for further conveying from those to whom you convey 544 the Program, the only way you could satisfy both those terms and this 545 License would be to refrain entirely from conveying the Program. 546 547 13. Remote Network Interaction; Use with the GNU General Public License. 548 549 Notwithstanding any other provision of this License, if you modify the 550 Program, your modified version must prominently offer all users 551 interacting with it remotely through a computer network (if your version 552 supports such interaction) an opportunity to receive the Corresponding 553 Source of your version by providing access to the Corresponding Source 554 from a network server at no charge, through some standard or customary 555 means of facilitating copying of software. This Corresponding Source 556 shall include the Corresponding Source for any work covered by version 3 557 of the GNU General Public License that is incorporated pursuant to the 558 following paragraph. 559 560 Notwithstanding any other provision of this License, you have 561 permission to link or combine any covered work with a work licensed 562 under version 3 of the GNU General Public License into a single 563 combined work, and to convey the resulting work. The terms of this 564 License will continue to apply to the part which is the covered work, 565 but the work with which it is combined will remain governed by version 566 3 of the GNU General Public License. 567 568 14. Revised Versions of this License. 569 570 The Free Software Foundation may publish revised and/or new versions of 571 the GNU Affero General Public License from time to time. Such new versions 572 will be similar in spirit to the present version, but may differ in detail to 573 address new problems or concerns. 574 575 Each version is given a distinguishing version number. If the 576 Program specifies that a certain numbered version of the GNU Affero General 577 Public License "or any later version" applies to it, you have the 578 option of following the terms and conditions either of that numbered 579 version or of any later version published by the Free Software 580 Foundation. If the Program does not specify a version number of the 581 GNU Affero General Public License, you may choose any version ever published 582 by the Free Software Foundation. 583 584 If the Program specifies that a proxy can decide which future 585 versions of the GNU Affero General Public License can be used, that proxy's 586 public statement of acceptance of a version permanently authorizes you 587 to choose that version for the Program. 588 589 Later license versions may give you additional or different 590 permissions. However, no additional obligations are imposed on any 591 author or copyright holder as a result of your choosing to follow a 592 later version. 593 594 15. Disclaimer of Warranty. 595 596 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY 597 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT 598 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY 599 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, 600 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR 601 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM 602 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF 603 ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 604 605 16. Limitation of Liability. 606 607 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING 608 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 609 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY 610 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE 611 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF 612 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD 613 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), 614 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF 615 SUCH DAMAGES. 616 617 17. Interpretation of Sections 15 and 16. 618 619 If the disclaimer of warranty and limitation of liability provided 620 above cannot be given local legal effect according to their terms, 621 reviewing courts shall apply local law that most closely approximates 622 an absolute waiver of all civil liability in connection with the 623 Program, unless a warranty or assumption of liability accompanies a 624 copy of the Program in return for a fee. 625 626 END OF TERMS AND CONDITIONS 627 628 How to Apply These Terms to Your New Programs 629 630 If you develop a new program, and you want it to be of the greatest 631 possible use to the public, the best way to achieve this is to make it 632 free software which everyone can redistribute and change under these terms. 633 634 To do so, attach the following notices to the program. It is safest 635 to attach them to the start of each source file to most effectively 636 state the exclusion of warranty; and each file should have at least 637 the "copyright" line and a pointer to where the full notice is found. 638 639 <one line to give the program's name and a brief idea of what it does.> 640 Copyright (C) <year> <name of author> 641 642 This program is free software: you can redistribute it and/or modify 643 it under the terms of the GNU Affero General Public License as published by 644 the Free Software Foundation, either version 3 of the License, or 645 (at your option) any later version. 646 647 This program is distributed in the hope that it will be useful, 648 but WITHOUT ANY WARRANTY; without even the implied warranty of 649 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the 650 GNU Affero General Public License for more details. 651 652 You should have received a copy of the GNU Affero General Public License 653 along with this program. If not, see <http://www.gnu.org/licenses/>. 654 655 Also add information on how to contact you by electronic and paper mail. 656 657 If your software can interact with users remotely through a computer 658 network, you should also make sure that it provides a way for users to 659 get its source. For example, if your program is a web application, its 660 interface could display a "Source" link that leads users to an archive 661 of the code. There are many ways you could offer source, and different 662 solutions will be better for different programs; see section 13 for the 663 specific requirements. 664 665 You should also get your employer (if you work as a programmer) or school, 666 if any, to sign a "copyright disclaimer" for the program, if necessary. 667 For more information on this, and how to apply and follow the GNU AGPL, see 668 <http://www.gnu.org/licenses/>.
