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