| JS | 2 | Version 3, 29 June 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 General Public License is a free, copyleft license for | |
| 11 | software and other kinds of works. | |
| 12 | ||
| 13 | The licenses for most software and other practical works are designed | |
| 14 | to take away your freedom to share and change the works. By contrast, | |
| 15 | the GNU General Public License is intended to guarantee your freedom to | |
| 16 | share and change all versions of a program--to make sure it remains free | |
| 17 | software for all its users. We, the Free Software Foundation, use the | |
| 18 | GNU General Public License for most of our software; it applies also to | |
| 19 | any other work released this way by its authors. You can apply it to | |
| 20 | your programs, too. | |
| 21 | ||
| 22 | When we speak of free software, we are referring to freedom, not | |
| 23 | price. Our General Public Licenses are designed to make sure that you | |
| 24 | have the freedom to distribute copies of free software (and charge for | |
| 25 | them if you wish), that you receive source code or can get it if you | |
| 26 | want it, that you can change the software or use pieces of it in new | |
| 27 | free programs, and that you know you can do these things. | |
| 28 | ||
| 29 | To protect your rights, we need to prevent others from denying you | |
| 30 | these rights or asking you to surrender the rights. Therefore, you have | |
| 31 | certain responsibilities if you distribute copies of the software, or if | |
| 32 | you modify it: responsibilities to respect the freedom of others. | |
| 33 | ||
| 34 | For example, if you distribute copies of such a program, whether | |
| 35 | gratis or for a fee, you must pass on to the recipients the same | |
| 36 | freedoms that you received. You must make sure that they, too, receive | |
| 37 | or can get the source code. And you must show them these terms so they | |
| 38 | know their rights. | |
| 39 | ||
| 40 | Developers that use the GNU GPL protect your rights with two steps: | |
| 41 | (1) assert copyright on the software, and (2) offer you this License | |
| 42 | giving you legal permission to copy, distribute and/or modify it. | |
| 43 | ||
| 44 | For the developers' and authors' protection, the GPL clearly explains | |
| 45 | that there is no warranty for this free software. For both users' and | |
| 46 | authors' sake, the GPL requires that modified versions be marked as | |
| 47 | changed, so that their problems will not be attributed erroneously to | |
| 48 | authors of previous versions. | |
| 49 | ||
| 50 | Some devices are designed to deny users access to install or run | |
| 51 | modified versions of the software inside them, although the manufacturer | |
| 52 | can do so. This is fundamentally incompatible with the aim of | |
| 53 | protecting users' freedom to change the software. The systematic | |
| 54 | pattern of such abuse occurs in the area of products for individuals to | |
| 55 | use, which is precisely where it is most unacceptable. Therefore, we | |
| 56 | have designed this version of the GPL to prohibit the practice for those | |
| 57 | products. If such problems arise substantially in other domains, we | |
| 58 | stand ready to extend this provision to those domains in future versions | |
| 59 | of the GPL, as needed to protect the freedom of users. | |
| 60 | ||
| 61 | Finally, every program is threatened constantly by software patents. | |
| 62 | States should not allow patents to restrict development and use of | |
| 63 | software on general-purpose computers, but in those that do, we wish to | |
| 64 | avoid the special danger that patents applied to a free program could | |
| 65 | make it effectively proprietary. To prevent this, the GPL assures that | |
| 66 | patents cannot be used to render the program non-free. | |
| 67 | ||
| 68 | The precise terms and conditions for copying, distribution and | |
| 69 | modification follow. | |
| 70 | ||
| 71 | TERMS AND CONDITIONS | |
| 72 | ||
| 73 | 0. Definitions. | |
| 74 | ||
| 75 | "This License" refers to version 3 of the GNU General Public License. | |
| 76 | ||
| 77 | "Copyright" also means copyright-like laws that apply to other kinds of | |
| 78 | works, such as semiconductor masks. | |
| 79 | ||
| 80 | "The Program" refers to any copyrightable work licensed under this | |
| 81 | License. Each licensee is addressed as "you". "Licensees" and | |
| 82 | "recipients" may be individuals or organizations. | |
| 83 | ||
| 84 | To "modify" a work means to copy from or adapt all or part of the work | |
| 85 | in a fashion requiring copyright permission, other than the making of an | |
| 86 | exact copy. The resulting work is called a "modified version" of the | |
| 87 | earlier work or a work "based on" the earlier work. | |
| 88 | ||
| 89 | A "covered work" means either the unmodified Program or a work based | |
| 90 | on the Program. | |
| 91 | ||
| 92 | To "propagate" a work means to do anything with it that, without | |
| 93 | permission, would make you directly or secondarily liable for | |
| 94 | infringement under applicable copyright law, except executing it on a | |
| 95 | computer or modifying a private copy. Propagation includes copying, | |
| 96 | distribution (with or without modification), making available to the | |
| 97 | public, and in some countries other activities as well. | |
| 98 | ||
| 99 | To "convey" a work means any kind of propagation that enables other | |
| 100 | parties to make or receive copies. Mere interaction with a user through | |
| 101 | a computer network, with no transfer of a copy, is not conveying. | |
| 102 | ||
| 103 | An interactive user interface displays "Appropriate Legal Notices" | |
| 104 | to the extent that it includes a convenient and prominently visible | |
| 105 | feature that (1) displays an appropriate copyright notice, and (2) | |
| 106 | tells the user that there is no warranty for the work (except to the | |
| 107 | extent that warranties are provided), that licensees may convey the | |
| 108 | work under this License, and how to view a copy of this License. If | |
| 109 | the interface presents a list of user commands or options, such as a | |
| 110 | menu, a prominent item in the list meets this criterion. | |
| 111 | ||
| 112 | 1. Source Code. | |
| 113 | ||
| 114 | The "source code" for a work means the preferred form of the work | |
| 115 | for making modifications to it. "Object code" means any non-source | |
| 116 | form of a work. | |
| 117 | ||
| 118 | A "Standard Interface" means an interface that either is an official | |
| 119 | standard defined by a recognized standards body, or, in the case of | |
| 120 | interfaces specified for a particular programming language, one that | |
| 121 | is widely used among developers working in that language. | |
| 122 | ||
| 123 | The "System Libraries" of an executable work include anything, other | |
| 124 | than the work as a whole, that (a) is included in the normal form of | |
| 125 | packaging a Major Component, but which is not part of that Major | |
| 126 | Component, and (b) serves only to enable use of the work with that | |
| 127 | Major Component, or to implement a Standard Interface for which an | |
| 128 | implementation is available to the public in source code form. A | |
| 129 | "Major Component", in this context, means a major essential component | |
| 130 | (kernel, window system, and so on) of the specific operating system | |
| 131 | (if any) on which the executable work runs, or a compiler used to | |
| 132 | produce the work, or an object code interpreter used to run it. | |
| 133 | ||
| 134 | The "Corresponding Source" for a work in object code form means all | |
| 135 | the source code needed to generate, install, and (for an executable | |
| 136 | work) run the object code and to modify the work, including scripts to | |
| 137 | control those activities. However, it does not include the work's | |
| 138 | System Libraries, or general-purpose tools or generally available free | |
| 139 | programs which are used unmodified in performing those activities but | |
| 140 | which are not part of the work. For example, Corresponding Source | |
| 141 | includes interface definition files associated with source files for | |
| 142 | the work, and the source code for shared libraries and dynamically | |
| 143 | linked subprograms that the work is specifically designed to require, | |
| 144 | such as by intimate data communication or control flow between those | |
| 145 | subprograms and other parts of the work. | |
| 146 | ||
| 147 | The Corresponding Source need not include anything that users | |
| 148 | can regenerate automatically from other parts of the Corresponding | |
| 149 | Source. | |
| 150 | ||
| 151 | The Corresponding Source for a work in source code form is that | |
| 152 | same work. | |
| 153 | ||
| 154 | 2. Basic Permissions. | |
| 155 | ||
| 156 | All rights granted under this License are granted for the term of | |
| 157 | copyright on the Program, and are irrevocable provided the stated | |
| 158 | conditions are met. This License explicitly affirms your unlimited | |
| 159 | permission to run the unmodified Program. The output from running a | |
| 160 | covered work is covered by this License only if the output, given its | |
| 161 | content, constitutes a covered work. This License acknowledges your | |
| 162 | rights of fair use or other equivalent, as provided by copyright law. | |
| 163 | ||
| 164 | You may make, run and propagate covered works that you do not | |
| 165 | convey, without conditions so long as your license otherwise remains | |
| 166 | in force. You may convey covered works to others for the sole purpose | |
| 167 | of having them make modifications exclusively for you, or provide you | |
| 168 | with facilities for running those works, provided that you comply with | |
| 169 | the terms of this License in conveying all material for which you do | |
| 170 | not control copyright. Those thus making or running the covered works | |
| 171 | for you must do so exclusively on your behalf, under your direction | |
| 172 | and control, on terms that prohibit them from making any copies of | |
| 173 | your copyrighted material outside their relationship with you. | |
| 174 | ||
| 175 | Conveying under any other circumstances is permitted solely under | |
| 176 | the conditions stated below. Sublicensing is not allowed; section 10 | |
| 177 | makes it unnecessary. | |
| 178 | ||
| 179 | 3. Protecting Users' Legal Rights From Anti-Circumvention Law. | |
| 180 | ||
| 181 | No covered work shall be deemed part of an effective technological | |
| 182 | measure under any applicable law fulfilling obligations under article | |
| 183 | 11 of the WIPO copyright treaty adopted on 20 December 1996, or | |
| 184 | similar laws prohibiting or restricting circumvention of such | |
| 185 | measures. | |
| 186 | ||
| 187 | When you convey a covered work, you waive any legal power to forbid | |
| 188 | circumvention of technological measures to the extent such circumvention | |
| 189 | is effected by exercising rights under this License with respect to | |
| 190 | the covered work, and you disclaim any intention to limit operation or | |
| 191 | modification of the work as a means of enforcing, against the work's | |
| 192 | users, your or third parties' legal rights to forbid circumvention of | |
| 193 | technological measures. | |
| 194 | ||
| 195 | 4. Conveying Verbatim Copies. | |
| 196 | ||
| 197 | You may convey verbatim copies of the Program's source code as you | |
| 198 | receive it, in any medium, provided that you conspicuously and | |
| 199 | appropriately publish on each copy an appropriate copyright notice; | |
| 200 | keep intact all notices stating that this License and any | |
| 201 | non-permissive terms added in accord with section 7 apply to the code; | |
| 202 | keep intact all notices of the absence of any warranty; and give all | |
| 203 | recipients a copy of this License along with the Program. | |
| 204 | ||
| 205 | You may charge any price or no price for each copy that you convey, | |
| 206 | and you may offer support or warranty protection for a fee. | |
| 207 | ||
| 208 | 5. Conveying Modified Source Versions. | |
| 209 | ||
| 210 | You may convey a work based on the Program, or the modifications to | |
| 211 | produce it from the Program, in the form of source code under the | |
| 212 | terms of section 4, provided that you also meet all of these conditions: | |
| 213 | ||
| 214 | a) The work must carry prominent notices stating that you modified | |
| 215 | it, and giving a relevant date. | |
| 216 | ||
| 217 | b) The work must carry prominent notices stating that it is | |
| 218 | released under this License and any conditions added under section | |
| 219 | 7. This requirement modifies the requirement in section 4 to | |
| 220 | "keep intact all notices". | |
| 221 | ||
| 222 | c) You must license the entire work, as a whole, under this | |
| 223 | License to anyone who comes into possession of a copy. This | |
| 224 | License will therefore apply, along with any applicable section 7 | |
| 225 | additional terms, to the whole of the work, and all its parts, | |
| 226 | regardless of how they are packaged. This License gives no | |
| 227 | permission to license the work in any other way, but it does not | |
| 228 | invalidate such permission if you have separately received it. | |
| 229 | ||
| 230 | d) If the work has interactive user interfaces, each must display | |
| 231 | Appropriate Legal Notices; however, if the Program has interactive | |
| 232 | interfaces that do not display Appropriate Legal Notices, your | |
| 233 | work need not make them do so. | |
| 234 | ||
| 235 | A compilation of a covered work with other separate and independent | |
| 236 | works, which are not by their nature extensions of the covered work, | |
| 237 | and which are not combined with it such as to form a larger program, | |
| 238 | in or on a volume of a storage or distribution medium, is called an | |
| 239 | "aggregate" if the compilation and its resulting copyright are not | |
| 240 | used to limit the access or legal rights of the compilation's users | |
| 241 | beyond what the individual works permit. Inclusion of a covered work | |
| 242 | in an aggregate does not cause this License to apply to the other | |
| 243 | parts of the aggregate. | |
| 244 | ||
| 245 | 6. Conveying Non-Source Forms. | |
| 246 | ||
| 247 | You may convey a covered work in object code form under the terms | |
| 248 | of sections 4 and 5, provided that you also convey the | |
| 249 | machine-readable Corresponding Source under the terms of this License, | |
| 250 | in one of these ways: | |
| 251 | ||
| 252 | a) Convey the object code in, or embodied in, a physical product | |
| 253 | (including a physical distribution medium), accompanied by the | |
| 254 | Corresponding Source fixed on a durable physical medium | |
| 255 | customarily used for software interchange. | |
| 256 | ||
| 257 | b) Convey the object code in, or embodied in, a physical product | |
| 258 | (including a physical distribution medium), accompanied by a | |
| 259 | written offer, valid for at least three years and valid for as | |
| 260 | long as you offer spare parts or customer support for that product | |
| 261 | model, to give anyone who possesses the object code either (1) a | |
| 262 | copy of the Corresponding Source for all the software in the | |
| 263 | product that is covered by this License, on a durable physical | |
| 264 | medium customarily used for software interchange, for a price no | |
| 265 | more than your reasonable cost of physically performing this | |
| 266 | conveying of source, or (2) access to copy the | |
| 267 | Corresponding Source from a network server at no charge. | |
| 268 | ||
| 269 | c) Convey individual copies of the object code with a copy of the | |
| 270 | written offer to provide the Corresponding Source. This | |
| 271 | alternative is allowed only occasionally and noncommercially, and | |
| 272 | only if you received the object code with such an offer, in accord | |
| 273 | with subsection 6b. | |
| 274 | ||
| 275 | d) Convey the object code by offering access from a designated | |
| 276 | place (gratis or for a charge), and offer equivalent access to the | |
| 277 | Corresponding Source in the same way through the same place at no | |
| 278 | further charge. You need not require recipients to copy the | |
| 279 | Corresponding Source along with the object code. If the place to | |
| 280 | copy the object code is a network server, the Corresponding Source | |
| 281 | may be on a different server (operated by you or a third party) | |
| 282 | that supports equivalent copying facilities, provided you maintain | |
| 283 | clear directions next to the object code saying where to find the | |
| 284 | Corresponding Source. Regardless of what server hosts the | |
| 285 | Corresponding Source, you remain obligated to ensure that it is | |
| 286 | available for as long as needed to satisfy these requirements. | |
| 287 | ||
| 288 | e) Convey the object code using peer-to-peer transmission, provided | |
| 289 | you inform other peers where the object code and Corresponding | |
| 290 | Source of the work are being offered to the general public at no | |
| 291 | charge under subsection 6d. | |
| 292 | ||
| 293 | A separable portion of the object code, whose source code is excluded | |
| 294 | from the Corresponding Source as a System Library, need not be | |
| 295 | included in conveying the object code work. | |
| 296 | ||
| 297 | A "User Product" is either (1) a "consumer product", which means any | |
| 298 | tangible personal property which is normally used for personal, family, | |
| 299 | or household purposes, or (2) anything designed or sold for incorporation | |
| 300 | into a dwelling. In determining whether a product is a consumer product, | |
| 301 | doubtful cases shall be resolved in favor of coverage. For a particular | |
| 302 | product received by a particular user, "normally used" refers to a | |
| 303 | typical or common use of that class of product, regardless of the status | |
| 304 | of the particular user or of the way in which the particular user | |
| 305 | actually uses, or expects or is expected to use, the product. A product | |
| 306 | is a consumer product regardless of whether the product has substantial | |
| 307 | commercial, industrial or non-consumer uses, unless such uses represent | |
| 308 | the only significant mode of use of the product. | |
| 309 | ||
| 310 | "Installation Information" for a User Product means any methods, | |
| 311 | procedures, authorization keys, or other information required to install | |
| 312 | and execute modified versions of a covered work in that User Product from | |
| 313 | a modified version of its Corresponding Source. The information must | |
| 314 | suffice to ensure that the continued functioning of the modified object | |
| 315 | code is in no case prevented or interfered with solely because | |
| 316 | modification has been made. | |
| 317 | ||
| 318 | If you convey an object code work under this section in, or with, or | |
| 319 | specifically for use in, a User Product, and the conveying occurs as | |
| 320 | part of a transaction in which the right of possession and use of the | |
| 321 | User Product is transferred to the recipient in perpetuity or for a | |
| 322 | fixed term (regardless of how the transaction is characterized), the | |
| 323 | Corresponding Source conveyed under this section must be accompanied | |
| 324 | by the Installation Information. But this requirement does not apply | |
| 325 | if neither you nor any third party retains the ability to install | |
| 326 | modified object code on the User Product (for example, the work has | |
| 327 | been installed in ROM). | |
| 328 | ||
| 329 | The requirement to provide Installation Information does not include a | |
| 330 | requirement to continue to provide support service, warranty, or updates | |
| 331 | for a work that has been modified or installed by the recipient, or for | |
| 332 | the User Product in which it has been modified or installed. Access to a | |
| 333 | network may be denied when the modification itself materially and | |
| 334 | adversely affects the operation of the network or violates the rules and | |
| 335 | protocols for communication across the network. | |
| 336 | ||
| 337 | Corresponding Source conveyed, and Installation Information provided, | |
| 338 | in accord with this section must be in a format that is publicly | |
| 339 | documented (and with an implementation available to the public in | |
| 340 | source code form), and must require no special password or key for | |
| 341 | unpacking, reading or copying. | |
| 342 | ||
| 343 | 7. Additional Terms. | |
| 344 | ||
| 345 | "Additional permissions" are terms that supplement the terms of this | |
| 346 | License by making exceptions from one or more of its conditions. | |
| 347 | Additional permissions that are applicable to the entire Program shall | |
| 348 | be treated as though they were included in this License, to the extent | |
| 349 | that they are valid under applicable law. If additional permissions | |
| 350 | apply only to part of the Program, that part may be used separately | |
| 351 | under those permissions, but the entire Program remains governed by | |
| 352 | this License without regard to the additional permissions. | |
| 353 | ||
| 354 | When you convey a copy of a covered work, you may at your option | |
| 355 | remove any additional permissions from that copy, or from any part of | |
| 356 | it. (Additional permissions may be written to require their own | |
| 357 | removal in certain cases when you modify the work.) You may place | |
| 358 | additional permissions on material, added by you to a covered work, | |
| 359 | for which you have or can give appropriate copyright permission. | |
| 360 | ||
| 361 | Notwithstanding any other provision of this License, for material you | |
| 362 | add to a covered work, you may (if authorized by the copyright holders of | |
| 363 | that material) supplement the terms of this License with terms: | |
| 364 | ||
| 365 | a) Disclaiming warranty or limiting liability differently from the | |
| 366 | terms of sections 15 and 16 of this License; or | |
| 367 | ||
| 368 | b) Requiring preservation of specified reasonable legal notices or | |
| 369 | author attributions in that material or in the Appropriate Legal | |
| 370 | Notices displayed by works containing it; or | |
| 371 | ||
| 372 | c) Prohibiting misrepresentation of the origin of that material, or | |
| 373 | requiring that modified versions of such material be marked in | |
| 374 | reasonable ways as different from the original version; or | |
| 375 | ||
| 376 | d) Limiting the use for publicity purposes of names of licensors or | |
| 377 | authors of the material; or | |
| 378 | ||
| 379 | e) Declining to grant rights under trademark law for use of some | |
| 380 | trade names, trademarks, or service marks; or | |
| 381 | ||
| 382 | f) Requiring indemnification of licensors and authors of that | |
| 383 | material by anyone who conveys the material (or modified versions of | |
| 384 | it) with contractual assumptions of liability to the recipient, for | |
| 385 | any liability that these contractual assumptions directly impose on | |
| 386 | those licensors and authors. | |
| 387 | ||
| 388 | All other non-permissive additional terms are considered "further | |
| 389 | restrictions" within the meaning of section 10. If the Program as you | |
| 390 | received it, or any part of it, contains a notice stating that it is | |
| 391 | governed by this License along with a term that is a further | |
| 392 | restriction, you may remove that term. If a license document contains | |
| 393 | a further restriction but permits relicensing or conveying under this | |
| 394 | License, you may add to a covered work material governed by the terms | |
| 395 | of that license document, provided that the further restriction does | |
| 396 | not survive such relicensing or conveying. | |
| 397 | ||
| 398 | If you add terms to a covered work in accord with this section, you | |
| 399 | must place, in the relevant source files, a statement of the | |
| 400 | additional terms that apply to those files, or a notice indicating | |
| 401 | where to find the applicable terms. | |
| 402 | ||
| 403 | Additional terms, permissive or non-permissive, may be stated in the | |
| 404 | form of a separately written license, or stated as exceptions; | |
| 405 | the above requirements apply either way. | |
| 406 | ||
| 407 | 8. Termination. | |
| 408 | ||
| 409 | You may not propagate or modify a covered work except as expressly | |
| 410 | provided under this License. Any attempt otherwise to propagate or | |
| 411 | modify it is void, and will automatically terminate your rights under | |
| 412 | this License (including any patent licenses granted under the third | |
| 413 | paragraph of section 11). | |
| 414 | ||
| 415 | However, if you cease all violation of this License, then your | |
| 416 | license from a particular copyright holder is reinstated (a) | |
| 417 | provisionally, unless and until the copyright holder explicitly and | |
| 418 | finally terminates your license, and (b) permanently, if the copyright | |
| 419 | holder fails to notify you of the violation by some reasonable means | |
| 420 | prior to 60 days after the cessation. | |
| 421 | ||
| 422 | Moreover, your license from a particular copyright holder is | |
| 423 | reinstated permanently if the copyright holder notifies you of the | |
| 424 | violation by some reasonable means, this is the first time you have | |
| 425 | received notice of violation of this License (for any work) from that | |
| 426 | copyright holder, and you cure the violation prior to 30 days after | |
| 427 | your receipt of the notice. | |
| 428 | ||
| 429 | Termination of your rights under this section does not terminate the | |
| 430 | licenses of parties who have received copies or rights from you under | |
| 431 | this License. If your rights have been terminated and not permanently | |
| 432 | reinstated, you do not qualify to receive new licenses for the same | |
| 433 | material under section 10. | |
| 434 | ||
| 435 | 9. Acceptance Not Required for Having Copies. | |
| 436 | ||
| 437 | You are not required to accept this License in order to receive or | |
| 438 | run a copy of the Program. Ancillary propagation of a covered work | |
| 439 | occurring solely as a consequence of using peer-to-peer transmission | |
| 440 | to receive a copy likewise does not require acceptance. However, | |
| 441 | nothing other than this License grants you permission to propagate or | |
| 442 | modify any covered work. These actions infringe copyright if you do | |
| 443 | not accept this License. Therefore, by modifying or propagating a | |
| 444 | covered work, you indicate your acceptance of this License to do so. | |
| 445 | ||
| 446 | 10. Automatic Licensing of Downstream Recipients. | |
| 447 | ||
| 448 | Each time you convey a covered work, the recipient automatically | |
| 449 | receives a license from the original licensors, to run, modify and | |
| 450 | propagate that work, subject to this License. You are not responsible | |
| 451 | for enforcing compliance by third parties with this License. | |
| 452 | ||
| 453 | An "entity transaction" is a transaction transferring control of an | |
| 454 | organization, or substantially all assets of one, or subdividing an | |
| 455 | organization, or merging organizations. If propagation of a covered | |
| 456 | work results from an entity transaction, each party to that | |
| 457 | transaction who receives a copy of the work also receives whatever | |
| 458 | licenses to the work the party's predecessor in interest had or could | |
| 459 | give under the previous paragraph, plus a right to possession of the | |
| 460 | Corresponding Source of the work from the predecessor in interest, if | |
| 461 | the predecessor has it or can get it with reasonable efforts. | |
| 462 | ||
| 463 | You may not impose any further restrictions on the exercise of the | |
| 464 | rights granted or affirmed under this License. For example, you may | |
| 465 | not impose a license fee, royalty, or other charge for exercise of | |
| 466 | rights granted under this License, and you may not initiate litigation | |
| 467 | (including a cross-claim or counterclaim in a lawsuit) alleging that | |
| 468 | any patent claim is infringed by making, using, selling, offering for | |
| 469 | sale, or importing the Program or any portion of it. | |
| 470 | ||
| 471 | 11. Patents. | |
| 472 | ||
| 473 | A "contributor" is a copyright holder who authorizes use under this | |
| 474 | License of the Program or a work on which the Program is based. The | |
| 475 | work thus licensed is called the contributor's "contributor version". | |
| 476 | ||
| 477 | A contributor's "essential patent claims" are all patent claims | |
| 478 | owned or controlled by the contributor, whether already acquired or | |
| 479 | hereafter acquired, that would be infringed by some manner, permitted | |
| 480 | by this License, of making, using, or selling its contributor version, | |
| 481 | but do not include claims that would be infringed only as a | |
| 482 | consequence of further modification of the contributor version. For | |
| 483 | purposes of this definition, "control" includes the right to grant | |
| 484 | patent sublicenses in a manner consistent with the requirements of | |
| 485 | this License. | |
| 486 | ||
| 487 | Each contributor grants you a non-exclusive, worldwide, royalty-free | |
| 488 | patent license under the contributor's essential patent claims, to | |
| 489 | make, use, sell, offer for sale, import and otherwise run, modify and | |
| 490 | propagate the contents of its contributor version. | |
| 491 | ||
| 492 | In the following three paragraphs, a "patent license" is any express | |
| 493 | agreement or commitment, however denominated, not to enforce a patent | |
| 494 | (such as an express permission to practice a patent or covenant not to | |
| 495 | sue for patent infringement). To "grant" such a patent license to a | |
| 496 | party means to make such an agreement or commitment not to enforce a | |
| 497 | patent against the party. | |
| 498 | ||
| 499 | If you convey a covered work, knowingly relying on a patent license, | |
| 500 | and the Corresponding Source of the work is not available for anyone | |
| 501 | to copy, free of charge and under the terms of this License, through a | |
| 502 | publicly available network server or other readily accessible means, | |
| 503 | then you must either (1) cause the Corresponding Source to be so | |
| 504 | available, or (2) arrange to deprive yourself of the benefit of the | |
| 505 | patent license for this particular work, or (3) arrange, in a manner | |
| 506 | consistent with the requirements of this License, to extend the patent | |
| 507 | license to downstream recipients. "Knowingly relying" means you have | |
| 508 | actual knowledge that, but for the patent license, your conveying the | |
| 509 | covered work in a country, or your recipient's use of the covered work | |
| 510 | in a country, would infringe one or more identifiable patents in that | |
| 511 | country that you have reason to believe are valid. | |
| 512 | ||
| 513 | If, pursuant to or in connection with a single transaction or | |
| 514 | arrangement, you convey, or propagate by procuring conveyance of, a | |
| 515 | covered work, and grant a patent license to some of the parties | |
| 516 | receiving the covered work authorizing them to use, propagate, modify | |
| 517 | or convey a specific copy of the covered work, then the patent license | |
| 518 | you grant is automatically extended to all recipients of the covered | |
| 519 | work and works based on it. | |
| 520 | ||
| 521 | A patent license is "discriminatory" if it does not include within | |
| 522 | the scope of its coverage, prohibits the exercise of, or is | |
| 523 | conditioned on the non-exercise of one or more of the rights that are | |
| 524 | specifically granted under this License. You may not convey a covered | |
| 525 | work if you are a party to an arrangement with a third party that is | |
| 526 | in the business of distributing software, under which you make payment | |
| 527 | to the third party based on the extent of your activity of conveying | |
| 528 | the work, and under which the third party grants, to any of the | |
| 529 | parties who would receive the covered work from you, a discriminatory | |
| 530 | patent license (a) in connection with copies of the covered work | |
| 531 | conveyed by you (or copies made from those copies), or (b) primarily | |
| 532 | for and in connection with specific products or compilations that | |
| 533 | contain the covered work, unless you entered into that arrangement, | |
| 534 | or that patent license was granted, prior to 28 March 2007. | |
| 535 | ||
| 536 | Nothing in this License shall be construed as excluding or limiting | |
| 537 | any implied license or other defenses to infringement that may | |
| 538 | otherwise be available to you under applicable patent law. | |
| 539 | ||
| 540 | 12. No Surrender of Others' Freedom. | |
| 541 | ||
| 542 | If conditions are imposed on you (whether by court order, agreement or | |
| 543 | otherwise) that contradict the conditions of this License, they do not | |
| 544 | excuse you from the conditions of this License. If you cannot convey a | |
| 545 | covered work so as to satisfy simultaneously your obligations under this | |
| 546 | License and any other pertinent obligations, then as a consequence you may | |
| 547 | not convey it at all. For example, if you agree to terms that obligate you | |
| 548 | to collect a royalty for further conveying from those to whom you convey | |
| 549 | the Program, the only way you could satisfy both those terms and this | |
| 550 | License would be to refrain entirely from conveying the Program. | |
| 551 | ||
| 552 | 13. Use with the GNU Affero General Public License. | |
| 553 | ||
| 554 | Notwithstanding any other provision of this License, you have | |
| 555 | permission to link or combine any covered work with a work licensed | |
| 556 | under version 3 of the GNU Affero General Public License into a single | |
| 557 | combined work, and to convey the resulting work. The terms of this | |
| 558 | License will continue to apply to the part which is the covered work, | |
| 559 | but the special requirements of the GNU Affero General Public License, | |
| 560 | section 13, concerning interaction through a network will apply to the | |
| 561 | combination as such. | |
| 562 | ||
| 563 | 14. Revised Versions of this License. | |
| 564 | ||
| 565 | The Free Software Foundation may publish revised and/or new versions of | |
| 566 | the GNU General Public License from time to time. Such new versions will | |
| 567 | be similar in spirit to the present version, but may differ in detail to | |
| 568 | address new problems or concerns. | |
| 569 | ||
| 570 | Each version is given a distinguishing version number. If the | |
| 571 | Program specifies that a certain numbered version of the GNU General | |
| 572 | Public License "or any later version" applies to it, you have the | |
| 573 | option of following the terms and conditions either of that numbered | |
| 574 | version or of any later version published by the Free Software | |
| 575 | Foundation. If the Program does not specify a version number of the | |
| 576 | GNU General Public License, you may choose any version ever published | |
| 577 | by the Free Software Foundation. | |
| 578 | ||
| 579 | If the Program specifies that a proxy can decide which future | |
| 580 | versions of the GNU General Public License can be used, that proxy's | |
| 581 | public statement of acceptance of a version permanently authorizes you | |
| 582 | to choose that version for the Program. | |
| 583 | ||
| 584 | Later license versions may give you additional or different | |
| 585 | permissions. However, no additional obligations are imposed on any | |
| 586 | author or copyright holder as a result of your choosing to follow a | |
| 587 | later version. | |
| 588 | ||
| 589 | 15. Disclaimer of Warranty. | |
| 590 | ||
| 591 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY | |
| 592 | APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT | |
| 593 | HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY | |
| 594 | OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, | |
| 595 | THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR | |
| 596 | PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM | |
| 597 | IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF | |
| 598 | ALL NECESSARY SERVICING, REPAIR OR CORRECTION. | |
| 599 | ||
| 600 | 16. Limitation of Liability. | |
| 601 | ||
| 602 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | |
| 603 | WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS | |
| 604 | THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY | |
| 605 | GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE | |
| 606 | USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF | |
| 607 | DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD | |
| 608 | PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), | |
| 609 | EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF | |
| 610 | SUCH DAMAGES. | |
| 611 | ||
| 612 | 17. Interpretation of Sections 15 and 16. | |
| 613 | ||
| 614 | If the disclaimer of warranty and limitation of liability provided | |
| 615 | above cannot be given local legal effect according to their terms, | |
| 616 | reviewing courts shall apply local law that most closely approximates | |
| 617 | an absolute waiver of all civil liability in connection with the | |
| 618 | Program, unless a warranty or assumption of liability accompanies a | |
| 619 | copy of the Program in return for a fee. | |
| 620 | ||
| 621 | END OF TERMS AND CONDITIONS | |
| 622 | ||
| 623 | How to Apply These Terms to Your New Programs | |
| 624 | ||
| 625 | If you develop a new program, and you want it to be of the greatest | |
| 626 | possible use to the public, the best way to achieve this is to make it | |
| 627 | free software which everyone can redistribute and change under these terms. | |
| 628 | ||
| 629 | To do so, attach the following notices to the program. It is safest | |
| 630 | to attach them to the start of each source file to most effectively | |
| 631 | state the exclusion of warranty; and each file should have at least | |
| 632 | the "copyright" line and a pointer to where the full notice is found. | |
| 633 | ||
| 634 | <one line to give the program's name and a brief idea of what it does.> | |
| 635 | Copyright (C) <year> <name of author> | |
| 636 | ||
| 637 | This program is free software: you can redistribute it and/or modify | |
| 638 | it under the terms of the GNU General Public License as published by | |
| 639 | the Free Software Foundation, either version 3 of the License, or | |
| 640 | (at your option) any later version. | |
| 641 | ||
| 642 | This program is distributed in the hope that it will be useful, | |
| 643 | but WITHOUT ANY WARRANTY; without even the implied warranty of | |
| 644 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the | |
| 645 | GNU General Public License for more details. | |
| 646 | ||
| 647 | You should have received a copy of the GNU General Public License | |
| 648 | along with this program. If not, see <http://www.gnu.org/licenses/>. | |
| 649 | ||
| 650 | Also add information on how to contact you by electronic and paper mail. | |
| 651 | ||
| 652 | If the program does terminal interaction, make it output a short | |
| 653 | notice like this when it starts in an interactive mode: | |
| 654 | ||
| 655 | <program> Copyright (C) <year> <name of author> | |
| 656 | This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. | |
| 657 | This is free software, and you are welcome to redistribute it | |
| 658 | under certain conditions; type `show c' for details. | |
| 659 | ||
| 660 | The hypothetical commands `show w' and `show c' should show the appropriate | |
| 661 | parts of the General Public License. Of course, your program's commands | |
| 662 | might be different; for a GUI interface, you would use an "about box". | |
| 663 | ||
| 664 | You should also get your employer (if you work as a programmer) or school, | |
| 665 | if any, to sign a "copyright disclaimer" for the program, if necessary. | |
| 666 | For more information on this, and how to apply and follow the GNU GPL, see | |
| 667 | <http://www.gnu.org/licenses/>. | |
| 668 | ||
| 669 | The GNU General Public License does not permit incorporating your program | |
| 670 | into proprietary programs. If your program is a subroutine library, you | |
| 671 | may consider it more useful to permit linking proprietary applications with | |
| 672 | the library. If this is what you want to do, use the GNU Lesser General | |
| 673 | Public License instead of this License. But first, please read | |
| 674 | <http://www.gnu.org/philosophy/why-not-lgpl.html>. | |
