| 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. |
