| 3 … | +Version 3, 19 November 2007 |
| 4 … | + |
| 5 … | +Copyright (C) 2007 Free Software Foundation, Inc. |
| 6 … | +<https://fsf.org/> |
| 7 … | + |
| 8 … | +Everyone is permitted to copy and distribute verbatim copies of this |
| 9 … | +license document, but changing it is not allowed. |
| 10 … | + |
| 11 … | +### Preamble |
| 12 … | + |
| 13 … | +The GNU Affero General Public License is a free, copyleft license for |
| 14 … | +software and other kinds of works, specifically designed to ensure |
| 15 … | +cooperation with the community in the case of network server software. |
| 16 … | + |
| 17 … | +The licenses for most software and other practical works are designed |
| 18 … | +to take away your freedom to share and change the works. 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 … | + <one line to give the program's name and a brief idea of what it does.> |
| 631 … | + Copyright (C) <year> <name of author> |
| 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 <https://www.gnu.org/licenses/>. |
| 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 <https://www.gnu.org/licenses/>. |
