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