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