| 2 GNU GENERAL PUBLIC LICENSE | |
| 3 Version 3, 29 June 2007 | |
| 4 | |
| 5 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> | |
| 6 Everyone is permitted to copy and distribute verbatim copies | |
| 7 of this license document, but changing it is not allowed. | |
| 8 | |
| 9 Preamble | |
| 10 | |
| 11 The GNU General Public License is a free, copyleft license for | |
| 12 software and other kinds of works. | |
| 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 the GNU General Public License is 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. We, the Free Software Foundation, use the | |
| 19 GNU General Public License for most of our software; it applies also to | |
| 20 any other work released this way by its authors. You can apply it to | |
| 21 your programs, too. | |
| 22 | |
| 23 When we speak of free software, we are referring to freedom, not | |
| 24 price. Our General Public Licenses are designed to make sure that you | |
| 25 have the freedom to distribute copies of free software (and charge for | |
| 26 them if you wish), that you receive source code or can get it if you | |
| 27 want it, that you can change the software or use pieces of it in new | |
| 28 free programs, and that you know you can do these things. | |
| 29 | |
| 30 To protect your rights, we need to prevent others from denying you | |
| 31 these rights or asking you to surrender the rights. Therefore, you have | |
| 32 certain responsibilities if you distribute copies of the software, or if | |
| 33 you modify it: responsibilities to respect the freedom of others. | |
| 34 | |
| 35 For example, if you distribute copies of such a program, whether | |
| 36 gratis or for a fee, you must pass on to the recipients the same | |
| 37 freedoms that you received. You must make sure that they, too, receive | |
| 38 or can get the source code. And you must show them these terms so they | |
| 39 know their rights. | |
| 40 | |
| 41 Developers that use the GNU GPL protect your rights with two steps: | |
| 42 (1) assert copyright on the software, and (2) offer you this License | |
| 43 giving you legal permission to copy, distribute and/or modify it. | |
| 44 | |
| 45 For the developers' and authors' protection, the GPL clearly explains | |
| 46 that there is no warranty for this free software. For both users' and | |
| 47 authors' sake, the GPL requires that modified versions be marked as | |
| 48 changed, so that their problems will not be attributed erroneously to | |
| 49 authors of previous versions. | |
| 50 | |
| 51 Some devices are designed to deny users access to install or run | |
| 52 modified versions of the software inside them, although the manufacturer | |
| 53 can do so. This is fundamentally incompatible with the aim of | |
| 54 protecting users' freedom to change the software. The systematic | |
| 55 pattern of such abuse occurs in the area of products for individuals to | |
| 56 use, which is precisely where it is most unacceptable. Therefore, we | |
| 57 have designed this version of the GPL to prohibit the practice for those | |
| 58 products. If such problems arise substantially in other domains, we | |
| 59 stand ready to extend this provision to those domains in future versions | |
| 60 of the GPL, as needed to protect the freedom of users. | |
| 61 | |
| 62 Finally, every program is threatened constantly by software patents. | |
| 63 States should not allow patents to restrict development and use of | |
| 64 software on general-purpose computers, but in those that do, we wish to | |
| 65 avoid the special danger that patents applied to a free program could | |
| 66 make it effectively proprietary. To prevent this, the GPL assures that | |
| 67 patents cannot be used to render the program non-free. | |
| 68 | |
| 69 The precise terms and conditions for copying, distribution and | |
| 70 modification follow. | |
| 71 | |
| 72 TERMS AND CONDITIONS | |
| 73 | |
| 74 0. Definitions. | |
| 75 | |
| 76 "This License" refers to version 3 of the GNU General Public License. | |
| 77 | |
| 78 "Copyright" also means copyright-like laws that apply to other kinds of | |
| 79 works, such as semiconductor masks. | |
| 80 | |
| 81 "The Program" refers to any copyrightable work licensed under this | |
| 82 License. Each licensee is addressed as "you". "Licensees" and | |
| 83 "recipients" may be individuals or organizations. | |
| 84 | |
| 85 To "modify" a work means to copy from or adapt all or part of the work | |
| 86 in a fashion requiring copyright permission, other than the making of an | |
| 87 exact copy. The resulting work is called a "modified version" of the | |
| 88 earlier work or a work "based on" the earlier work. | |
| 89 | |
| 90 A "covered work" means either the unmodified Program or a work based | |
| 91 on the Program. | |
| 92 | |
| 93 To "propagate" a work means to do anything with it that, without | |
| 94 permission, would make you directly or secondarily liable for | |
| 95 infringement under applicable copyright law, except executing it on a | |
| 96 computer or modifying a private copy. Propagation includes copying, | |
| 97 distribution (with or without modification), making available to the | |
| 98 public, and in some countries other activities as well. | |
| 99 | |
| 100 To "convey" a work means any kind of propagation that enables other | |
| 101 parties to make or receive copies. Mere interaction with a user through | |
| 102 a computer network, with no transfer of a copy, is not conveying. | |
| 103 | |
| 104 An interactive user interface displays "Appropriate Legal Notices" | |
| 105 to the extent that it includes a convenient and prominently visible | |
| 106 feature that (1) displays an appropriate copyright notice, and (2) | |
| 107 tells the user that there is no warranty for the work (except to the | |
| 108 extent that warranties are provided), that licensees may convey the | |
| 109 work under this License, and how to view a copy of this License. If | |
| 110 the interface presents a list of user commands or options, such as a | |
| 111 menu, a prominent item in the list meets this criterion. | |
| 112 | |
| 113 1. Source Code. | |
| 114 | |
| 115 The "source code" for a work means the preferred form of the work | |
| 116 for making modifications to it. "Object code" means any non-source | |
| 117 form of a work. | |
| 118 | |
| 119 A "Standard Interface" means an interface that either is an official | |
| 120 standard defined by a recognized standards body, or, in the case of | |
| 121 interfaces specified for a particular programming language, one that | |
| 122 is widely used among developers working in that language. | |
| 123 | |
| 124 The "System Libraries" of an executable work include anything, other | |
| 125 than the work as a whole, that (a) is included in the normal form of | |
| 126 packaging a Major Component, but which is not part of that Major | |
| 127 Component, and (b) serves only to enable use of the work with that | |
| 128 Major Component, or to implement a Standard Interface for which an | |
| 129 implementation is available to the public in source code form. A | |
| 130 "Major Component", in this context, means a major essential component | |
| 131 (kernel, window system, and so on) of the specific operating system | |
| 132 (if any) on which the executable work runs, or a compiler used to | |
| 133 produce the work, or an object code interpreter used to run it. | |
| 134 | |
| 135 The "Corresponding Source" for a work in object code form means all | |
| 136 the source code needed to generate, install, and (for an executable | |
| 137 work) run the object code and to modify the work, including scripts to | |
| 138 control those activities. However, it does not include the work's | |
| 139 System Libraries, or general-purpose tools or generally available free | |
| 140 programs which are used unmodified in performing those activities but | |
| 141 which are not part of the work. For example, Corresponding Source | |
| 142 includes interface definition files associated with source files for | |
| 143 the work, and the source code for shared libraries and dynamically | |
| 144 linked subprograms that the work is specifically designed to require, | |
| 145 such as by intimate data communication or control flow between those | |
| 146 subprograms and other parts of the work. | |
| 147 | |
| 148 The Corresponding Source need not include anything that users | |
| 149 can regenerate automatically from other parts of the Corresponding | |
| 150 Source. | |
| 151 | |
| 152 The Corresponding Source for a work in source code form is that | |
| 153 same work. | |
| 154 | |
| 155 2. Basic Permissions. | |
| 156 | |
| 157 All rights granted under this License are granted for the term of | |
| 158 copyright on the Program, and are irrevocable provided the stated | |
| 159 conditions are met. This License explicitly affirms your unlimited | |
| 160 permission to run the unmodified Program. The output from running a | |
| 161 covered work is covered by this License only if the output, given its | |
| 162 content, constitutes a covered work. This License acknowledges your | |
| 163 rights of fair use or other equivalent, as provided by copyright law. | |
| 164 | |
| 165 You may make, run and propagate covered works that you do not | |
| 166 convey, without conditions so long as your license otherwise remains | |
| 167 in force. You may convey covered works to others for the sole purpose | |
| 168 of having them make modifications exclusively for you, or provide you | |
| 169 with facilities for running those works, provided that you comply with | |
| 170 the terms of this License in conveying all material for which you do | |
| 171 not control copyright. Those thus making or running the covered works | |
| 172 for you must do so exclusively on your behalf, under your direction | |
| 173 and control, on terms that prohibit them from making any copies of | |
| 174 your copyrighted material outside their relationship with you. | |
| 175 | |
| 176 Conveying under any other circumstances is permitted solely under | |
| 177 the conditions stated below. Sublicensing is not allowed; section 10 | |
| 178 makes it unnecessary. | |
| 179 | |
| 180 3. Protecting Users' Legal Rights From Anti-Circumvention Law. | |
| 181 | |
| 182 No covered work shall be deemed part of an effective technological | |
| 183 measure under any applicable law fulfilling obligations under article | |
| 184 11 of the WIPO copyright treaty adopted on 20 December 1996, or | |
| 185 similar laws prohibiting or restricting circumvention of such | |
| 186 measures. | |
| 187 | |
| 188 When you convey a covered work, you waive any legal power to forbid | |
| 189 circumvention of technological measures to the extent such circumvention | |
| 190 is effected by exercising rights under this License with respect to | |
| 191 the covered work, and you disclaim any intention to limit operation or | |
| 192 modification of the work as a means of enforcing, against the work's | |
| 193 users, your or third parties' legal rights to forbid circumvention of | |
| 194 technological measures. | |
| 195 | |
| 196 4. Conveying Verbatim Copies. | |
| 197 | |
| 198 You may convey verbatim copies of the Program's source code as you | |
| 199 receive it, in any medium, provided that you conspicuously and | |
| 200 appropriately publish on each copy an appropriate copyright notice; | |
| 201 keep intact all notices stating that this License and any | |
| 202 non-permissive terms added in accord with section 7 apply to the code; | |
| 203 keep intact all notices of the absence of any warranty; and give all | |
| 204 recipients a copy of this License along with the Program. | |
| 205 | |
| 206 You may charge any price or no price for each copy that you convey, | |
| 207 and you may offer support or warranty protection for a fee. | |
| 208 | |
| 209 5. Conveying Modified Source Versions. | |
| 210 | |
| 211 You may convey a work based on the Program, or the modifications to | |
| 212 produce it from the Program, in the form of source code under the | |
| 213 terms of section 4, provided that you also meet all of these conditions: | |
| 214 | |
| 215 a) The work must carry prominent notices stating that you modified | |
| 216 it, and giving a relevant date. | |
| 217 | |
| 218 b) The work must carry prominent notices stating that it is | |
| 219 released under this License and any conditions added under section | |
| 220 7. This requirement modifies the requirement in section 4 to | |
| 221 "keep intact all notices". | |
| 222 | |
| 223 c) You must license the entire work, as a whole, under this | |
| 224 License to anyone who comes into possession of a copy. This | |
| 225 License will therefore apply, along with any applicable section 7 | |
| 226 additional terms, to the whole of the work, and all its parts, | |
| 227 regardless of how they are packaged. This License gives no | |
| 228 permission to license the work in any other way, but it does not | |
| 229 invalidate such permission if you have separately received it. | |
| 230 | |
| 231 d) If the work has interactive user interfaces, each must display | |
| 232 Appropriate Legal Notices; however, if the Program has interactive | |
| 233 interfaces that do not display Appropriate Legal Notices, your | |
| 234 work need not make them do so. | |
| 235 | |
| 236 A compilation of a covered work with other separate and independent | |
| 237 works, which are not by their nature extensions of the covered work, | |
| 238 and which are not combined with it such as to form a larger program, | |
| 239 in or on a volume of a storage or distribution medium, is called an | |
| 240 "aggregate" if the compilation and its resulting copyright are not | |
| 241 used to limit the access or legal rights of the compilation's users | |
| 242 beyond what the individual works permit. Inclusion of a covered work | |
| 243 in an aggregate does not cause this License to apply to the other | |
| 244 parts of the aggregate. | |
| 245 | |
| 246 6. Conveying Non-Source Forms. | |
| 247 | |
| 248 You may convey a covered work in object code form under the terms | |
| 249 of sections 4 and 5, provided that you also convey the | |
| 250 machine-readable Corresponding Source under the terms of this License, | |
| 251 in one of these ways: | |
| 252 | |
| 253 a) Convey the object code in, or embodied in, a physical product | |
| 254 (including a physical distribution medium), accompanied by the | |
| 255 Corresponding Source fixed on a durable physical medium | |
| 256 customarily used for software interchange. | |
| 257 | |
| 258 b) Convey the object code in, or embodied in, a physical product | |
| 259 (including a physical distribution medium), accompanied by a | |
| 260 written offer, valid for at least three years and valid for as | |
| 261 long as you offer spare parts or customer support for that product | |
| 262 model, to give anyone who possesses the object code either (1) a | |
| 263 copy of the Corresponding Source for all the software in the | |
| 264 product that is covered by this License, on a durable physical | |
| 265 medium customarily used for software interchange, for a price no | |
| 266 more than your reasonable cost of physically performing this | |
| 267 conveying of source, or (2) access to copy the | |
| 268 Corresponding Source from a network server at no charge. | |
| 269 | |
| 270 c) Convey individual copies of the object code with a copy of the | |
| 271 written offer to provide the Corresponding Source. This | |
| 272 alternative is allowed only occasionally and noncommercially, and | |
| 273 only if you received the object code with such an offer, in accord | |
| 274 with subsection 6b. | |
| 275 | |
| 276 d) Convey the object code by offering access from a designated | |
| 277 place (gratis or for a charge), and offer equivalent access to the | |
| 278 Corresponding Source in the same way through the same place at no | |
| 279 further charge. You need not require recipients to copy the | |
| 280 Corresponding Source along with the object code. If the place to | |
| 281 copy the object code is a network server, the Corresponding Source | |
| 282 may be on a different server (operated by you or a third party) | |
| 283 that supports equivalent copying facilities, provided you maintain | |
| 284 clear directions next to the object code saying where to find the | |
| 285 Corresponding Source. Regardless of what server hosts the | |
| 286 Corresponding Source, you remain obligated to ensure that it is | |
| 287 available for as long as needed to satisfy these requirements. | |
| 288 | |
| 289 e) Convey the object code using peer-to-peer transmission, provided | |
| 290 you inform other peers where the object code and Corresponding | |
| 291 Source of the work are being offered to the general public at no | |
| 292 charge under subsection 6d. | |
| 293 | |
| 294 A separable portion of the object code, whose source code is excluded | |
| 295 from the Corresponding Source as a System Library, need not be | |
| 296 included in conveying the object code work. | |
| 297 | |
| 298 A "User Product" is either (1) a "consumer product", which means any | |
| 299 tangible personal property which is normally used for personal, family, | |
| 300 or household purposes, or (2) anything designed or sold for incorporation | |
| 301 into a dwelling. In determining whether a product is a consumer product, | |
| 302 doubtful cases shall be resolved in favor of coverage. For a particular | |
| 303 product received by a particular user, "normally used" refers to a | |
| 304 typical or common use of that class of product, regardless of the status | |
| 305 of the particular user or of the way in which the particular user | |
| 306 actually uses, or expects or is expected to use, the product. A product | |
| 307 is a consumer product regardless of whether the product has substantial | |
| 308 commercial, industrial or non-consumer uses, unless such uses represent | |
| 309 the only significant mode of use of the product. | |
| 310 | |
| 311 "Installation Information" for a User Product means any methods, | |
| 312 procedures, authorization keys, or other information required to install | |
| 313 and execute modified versions of a covered work in that User Product from | |
| 314 a modified version of its Corresponding Source. The information must | |
| 315 suffice to ensure that the continued functioning of the modified object | |
| 316 code is in no case prevented or interfered with solely because | |
| 317 modification has been made. | |
| 318 | |
| 319 If you convey an object code work under this section in, or with, or | |
| 320 specifically for use in, a User Product, and the conveying occurs as | |
| 321 part of a transaction in which the right of possession and use of the | |
| 322 User Product is transferred to the recipient in perpetuity or for a | |
| 323 fixed term (regardless of how the transaction is characterized), the | |
| 324 Corresponding Source conveyed under this section must be accompanied | |
| 325 by the Installation Information. But this requirement does not apply | |
| 326 if neither you nor any third party retains the ability to install | |
| 327 modified object code on the User Product (for example, the work has | |
| 328 been installed in ROM). | |
| 329 | |
| 330 The requirement to provide Installation Information does not include a | |
| 331 requirement to continue to provide support service, warranty, or updates | |
| 332 for a work that has been modified or installed by the recipient, or for | |
| 333 the User Product in which it has been modified or installed. Access to a | |
| 334 network may be denied when the modification itself materially and | |
| 335 adversely affects the operation of the network or violates the rules and | |
| 336 protocols for communication across the network. | |
| 337 | |
| 338 Corresponding Source conveyed, and Installation Information provided, | |
| 339 in accord with this section must be in a format that is publicly | |
| 340 documented (and with an implementation available to the public in | |
| 341 source code form), and must require no special password or key for | |
| 342 unpacking, reading or copying. | |
| 343 | |
| 344 7. Additional Terms. | |
| 345 | |
| 346 "Additional permissions" are terms that supplement the terms of this | |
| 347 License by making exceptions from one or more of its conditions. | |
| 348 Additional permissions that are applicable to the entire Program shall | |
| 349 be treated as though they were included in this License, to the extent | |
| 350 that they are valid under applicable law. If additional permissions | |
| 351 apply only to part of the Program, that part may be used separately | |
| 352 under those permissions, but the entire Program remains governed by | |
| 353 this License without regard to the additional permissions. | |
| 354 | |
| 355 When you convey a copy of a covered work, you may at your option | |
| 356 remove any additional permissions from that copy, or from any part of | |
| 357 it. (Additional permissions may be written to require their own | |
| 358 removal in certain cases when you modify the work.) You may place | |
| 359 additional permissions on material, added by you to a covered work, | |
| 360 for which you have or can give appropriate copyright permission. | |
| 361 | |
| 362 Notwithstanding any other provision of this License, for material you | |
| 363 add to a covered work, you may (if authorized by the copyright holders of | |
| 364 that material) supplement the terms of this License with terms: | |
| 365 | |
| 366 a) Disclaiming warranty or limiting liability differently from the | |
| 367 terms of sections 15 and 16 of this License; or | |
| 368 | |
| 369 b) Requiring preservation of specified reasonable legal notices or | |
| 370 author attributions in that material or in the Appropriate Legal | |
| 371 Notices displayed by works containing it; or | |
| 372 | |
| 373 c) Prohibiting misrepresentation of the origin of that material, or | |
| 374 requiring that modified versions of such material be marked in | |
| 375 reasonable ways as different from the original version; or | |
| 376 | |
| 377 d) Limiting the use for publicity purposes of names of licensors or | |
| 378 authors of the material; or | |
| 379 | |
| 380 e) Declining to grant rights under trademark law for use of some | |
| 381 trade names, trademarks, or service marks; or | |
| 382 | |
| 383 f) Requiring indemnification of licensors and authors of that | |
| 384 material by anyone who conveys the material (or modified versions of | |
| 385 it) with contractual assumptions of liability to the recipient, for | |
| 386 any liability that these contractual assumptions directly impose on | |
| 387 those licensors and authors. | |
| 388 | |
| 389 All other non-permissive additional terms are considered "further | |
| 390 restrictions" within the meaning of section 10. If the Program as you | |
| 391 received it, or any part of it, contains a notice stating that it is | |
| 392 governed by this License along with a term that is a further | |
| 393 restriction, you may remove that term. If a license document contains | |
| 394 a further restriction but permits relicensing or conveying under this | |
| 395 License, you may add to a covered work material governed by the terms | |
| 396 of that license document, provided that the further restriction does | |
| 397 not survive such relicensing or conveying. | |
| 398 | |
| 399 If you add terms to a covered work in accord with this section, you | |
| 400 must place, in the relevant source files, a statement of the | |
| 401 additional terms that apply to those files, or a notice indicating | |
| 402 where to find the applicable terms. | |
| 403 | |
| 404 Additional terms, permissive or non-permissive, may be stated in the | |
| 405 form of a separately written license, or stated as exceptions; | |
| 406 the above requirements apply either way. | |
| 407 | |
| 408 8. Termination. | |
| 409 | |
| 410 You may not propagate or modify a covered work except as expressly | |
| 411 provided under this License. Any attempt otherwise to propagate or | |
| 412 modify it is void, and will automatically terminate your rights under | |
| 413 this License (including any patent licenses granted under the third | |
| 414 paragraph of section 11). | |
| 415 | |
| 416 However, if you cease all violation of this License, then your | |
| 417 license from a particular copyright holder is reinstated (a) | |
| 418 provisionally, unless and until the copyright holder explicitly and | |
| 419 finally terminates your license, and (b) permanently, if the copyright | |
| 420 holder fails to notify you of the violation by some reasonable means | |
| 421 prior to 60 days after the cessation. | |
| 422 | |
| 423 Moreover, your license from a particular copyright holder is | |
| 424 reinstated permanently if the copyright holder notifies you of the | |
| 425 violation by some reasonable means, this is the first time you have | |
| 426 received notice of violation of this License (for any work) from that | |
| 427 copyright holder, and you cure the violation prior to 30 days after | |
| 428 your receipt of the notice. | |
| 429 | |
| 430 Termination of your rights under this section does not terminate the | |
| 431 licenses of parties who have received copies or rights from you under | |
| 432 this License. If your rights have been terminated and not permanently | |
| 433 reinstated, you do not qualify to receive new licenses for the same | |
| 434 material under section 10. | |

| 436 9. Acceptance Not Required for Having Copies. | |
| 437 | |
| 438 You are not required to accept this License in order to receive or | |
| 439 run a copy of the Program. Ancillary propagation of a covered work | |
| 440 occurring solely as a consequence of using peer-to-peer transmission | |
| 441 to receive a copy likewise does not require acceptance. However, | |
| 442 nothing other than this License grants you permission to propagate or | |
| 443 modify any covered work. These actions infringe copyright if you do | |
| 444 not accept this License. Therefore, by modifying or propagating a | |
| 445 covered work, you indicate your acceptance of this License to do so. | |
| 446 | |
| 447 10. Automatic Licensing of Downstream Recipients. | |
| 448 | |
| 449 Each time you convey a covered work, the recipient automatically | |
| 450 receives a license from the original licensors, to run, modify and | |
| 451 propagate that work, subject to this License. You are not responsible | |
| 452 for enforcing compliance by third parties with this License. | |
| 453 | |
| 454 An "entity transaction" is a transaction transferring control of an | |
| 455 organization, or substantially all assets of one, or subdividing an | |
| 456 organization, or merging organizations. If propagation of a covered | |
| 457 work results from an entity transaction, each party to that | |
| 458 transaction who receives a copy of the work also receives whatever | |
| 459 licenses to the work the party's predecessor in interest had or could | |
| 460 give under the previous paragraph, plus a right to possession of the | |
| 461 Corresponding Source of the work from the predecessor in interest, if | |
| 462 the predecessor has it or can get it with reasonable efforts. | |
| 463 | |
| 464 You may not impose any further restrictions on the exercise of the | |
| 465 rights granted or affirmed under this License. For example, you may | |
| 466 not impose a license fee, royalty, or other charge for exercise of | |
| 467 rights granted under this License, and you may not initiate litigation | |
| 468 (including a cross-claim or counterclaim in a lawsuit) alleging that | |
| 469 any patent claim is infringed by making, using, selling, offering for | |
| 470 sale, or importing the Program or any portion of it. | |
| 471 | |
| 472 11. Patents. | |
| 473 | |
| 474 A "contributor" is a copyright holder who authorizes use under this | |
| 475 License of the Program or a work on which the Program is based. The | |
| 476 work thus licensed is called the contributor's "contributor version". | |
| 477 | |
| 478 A contributor's "essential patent claims" are all patent claims | |
| 479 owned or controlled by the contributor, whether already acquired or | |
| 480 hereafter acquired, that would be infringed by some manner, permitted | |
| 481 by this License, of making, using, or selling its contributor version, | |
| 482 but do not include claims that would be infringed only as a | |
| 483 consequence of further modification of the contributor version. For | |
| 484 purposes of this definition, "control" includes the right to grant | |
| 485 patent sublicenses in a manner consistent with the requirements of | |
| 486 this License. | |
| 487 | |
| 488 Each contributor grants you a non-exclusive, worldwide, royalty-free | |
| 489 patent license under the contributor's essential patent claims, to | |
| 490 make, use, sell, offer for sale, import and otherwise run, modify and | |
| 491 propagate the contents of its contributor version. | |
| 492 | |
| 493 In the following three paragraphs, a "patent license" is any express | |
| 494 agreement or commitment, however denominated, not to enforce a patent | |
| 495 (such as an express permission to practice a patent or covenant not to | |
| 496 sue for patent infringement). To "grant" such a patent license to a | |
| 497 party means to make such an agreement or commitment not to enforce a | |
| 498 patent against the party. | |
| 499 | |
| 500 If you convey a covered work, knowingly relying on a patent license, | |
| 501 and the Corresponding Source of the work is not available for anyone | |
| 502 to copy, free of charge and under the terms of this License, through a | |
| 503 publicly available network server or other readily accessible means, | |
| 504 then you must either (1) cause the Corresponding Source to be so | |
| 505 available, or (2) arrange to deprive yourself of the benefit of the | |
| 506 patent license for this particular work, or (3) arrange, in a manner | |
| 507 consistent with the requirements of this License, to extend the patent | |
| 508 license to downstream recipients. "Knowingly relying" means you have | |
| 509 actual knowledge that, but for the patent license, your conveying the | |
| 510 covered work in a country, or your recipient's use of the covered work | |
| 511 in a country, would infringe one or more identifiable patents in that | |
| 512 country that you have reason to believe are valid. | |
| 513 | |
| 514 If, pursuant to or in connection with a single transaction or | |
| 515 arrangement, you convey, or propagate by procuring conveyance of, a | |
| 516 covered work, and grant a patent license to some of the parties | |
| 517 receiving the covered work authorizing them to use, propagate, modify | |
| 518 or convey a specific copy of the covered work, then the patent license | |
| 519 you grant is automatically extended to all recipients of the covered | |
| 520 work and works based on it. | |
| 521 | |
| 522 A patent license is "discriminatory" if it does not include within | |
| 523 the scope of its coverage, prohibits the exercise of, or is | |
| 524 conditioned on the non-exercise of one or more of the rights that are | |
| 525 specifically granted under this License. You may not convey a covered | |
| 526 work if you are a party to an arrangement with a third party that is | |
| 527 in the business of distributing software, under which you make payment | |
| 528 to the third party based on the extent of your activity of conveying | |
| 529 the work, and under which the third party grants, to any of the | |
| 530 parties who would receive the covered work from you, a discriminatory | |
| 531 patent license (a) in connection with copies of the covered work | |
| 532 conveyed by you (or copies made from those copies), or (b) primarily | |
| 533 for and in connection with specific products or compilations that | |
| 534 contain the covered work, unless you entered into that arrangement, | |
| 535 or that patent license was granted, prior to 28 March 2007. | |
| 536 | |
| 537 Nothing in this License shall be construed as excluding or limiting | |
| 538 any implied license or other defenses to infringement that may | |
| 539 otherwise be available to you under applicable patent law. | |
| 540 | |
| 541 12. No Surrender of Others' Freedom. | |
| 542 | |
| 543 If conditions are imposed on you (whether by court order, agreement or | |
| 544 otherwise) that contradict the conditions of this License, they do not | |
| 545 excuse you from the conditions of this License. If you cannot convey a | |
| 546 covered work so as to satisfy simultaneously your obligations under this | |
| 547 License and any other pertinent obligations, then as a consequence you may | |
| 548 not convey it at all. For example, if you agree to terms that obligate you | |
| 549 to collect a royalty for further conveying from those to whom you convey | |
| 550 the Program, the only way you could satisfy both those terms and this | |
| 551 License would be to refrain entirely from conveying the Program. | |
| 552 | |
| 553 13. Use with the GNU Affero General Public License. | |
| 554 | |
| 555 Notwithstanding any other provision of this License, you have | |
| 556 permission to link or combine any covered work with a work licensed | |
| 557 under version 3 of the GNU Affero General Public License into a single | |
| 558 combined work, and to convey the resulting work. The terms of this | |
| 559 License will continue to apply to the part which is the covered work, | |
| 560 but the special requirements of the GNU Affero General Public License, | |
| 561 section 13, concerning interaction through a network will apply to the | |
| 562 combination as such. | |
| 563 | |
| 564 14. Revised Versions of this License. | |
| 565 | |
| 566 The Free Software Foundation may publish revised and/or new versions of | |
| 567 the GNU General Public License from time to time. Such new versions will | |
| 568 be similar in spirit to the present version, but may differ in detail to | |
| 569 address new problems or concerns. | |
| 570 | |
| 571 Each version is given a distinguishing version number. If the | |
| 572 Program specifies that a certain numbered version of the GNU General | |
| 573 Public License "or any later version" applies to it, you have the | |
| 574 option of following the terms and conditions either of that numbered | |
| 575 version or of any later version published by the Free Software | |
| 576 Foundation. If the Program does not specify a version number of the | |
| 577 GNU General Public License, you may choose any version ever published | |
| 578 by the Free Software Foundation. | |
| 579 | |
| 580 If the Program specifies that a proxy can decide which future | |
| 581 versions of the GNU General Public License can be used, that proxy's | |
| 582 public statement of acceptance of a version permanently authorizes you | |
| 583 to choose that version for the Program. | |
| 584 | |
| 585 Later license versions may give you additional or different | |
| 586 permissions. However, no additional obligations are imposed on any | |
| 587 author or copyright holder as a result of your choosing to follow a | |
| 588 later version. | |
| 589 | |
| 590 15. Disclaimer of Warranty. | |
| 591 | |
| 592 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY | |
| 593 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT | |
| 594 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY | |
| 595 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, | |
| 596 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR | |
| 597 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM | |
| 598 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF | |
| 599 ALL NECESSARY SERVICING, REPAIR OR CORRECTION. | |
| 600 | |
| 601 16. Limitation of Liability. | |
| 602 | |
| 603 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING | |
| 604 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS | |
| 605 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY | |
| 606 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE | |
| 607 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF | |
| 608 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD | |
| 609 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), | |
| 610 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF | |
| 611 SUCH DAMAGES. | |
| 612 | |
| 613 17. Interpretation of Sections 15 and 16. | |
| 614 | |
| 615 If the disclaimer of warranty and limitation of liability provided | |
| 616 above cannot be given local legal effect according to their terms, | |
| 617 reviewing courts shall apply local law that most closely approximates | |
| 618 an absolute waiver of all civil liability in connection with the | |
| 619 Program, unless a warranty or assumption of liability accompanies a | |
| 620 copy of the Program in return for a fee. | |
| 621 | |
| 622 END OF TERMS AND CONDITIONS | |
| 623 | |
| 624 How to Apply These Terms to Your New Programs | |
| 625 | |
| 626 If you develop a new program, and you want it to be of the greatest | |
| 627 possible use to the public, the best way to achieve this is to make it | |
| 628 free software which everyone can redistribute and change under these terms. | |
| 629 | |
| 630 To do so, attach the following notices to the program. It is safest | |
| 631 to attach them to the start of each source file to most effectively | |
| 632 state the exclusion of warranty; and each file should have at least | |
| 633 the "copyright" line and a pointer to where the full notice is found. | |
| 634 | |
| 635 <one line to give the program's name and a brief idea of what it does.> | |
| 636 Copyright (C) <year> <name of author> | |
| 637 | |
| 638 This program is free software: you can redistribute it and/or modify | |
| 639 it under the terms of the GNU General Public License as published by | |
| 640 the Free Software Foundation, either version 3 of the License, or | |
| 641 (at your option) any later version. | |
| 642 | |
| 643 This program is distributed in the hope that it will be useful, | |
| 644 but WITHOUT ANY WARRANTY; without even the implied warranty of | |
| 645 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the | |
| 646 GNU General Public License for more details. | |
| 647 | |
| 648 You should have received a copy of the GNU General Public License | |
| 649 along with this program. If not, see <http://www.gnu.org/licenses/>. | |
| 650 | |
| 651 Also add information on how to contact you by electronic and paper mail. | |
| 652 | |
| 653 If the program does terminal interaction, make it output a short | |
| 654 notice like this when it starts in an interactive mode: | |
| 655 | |
| 656 <program> Copyright (C) <year> <name of author> | |
| 657 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. | |
| 658 This is free software, and you are welcome to redistribute it | |
| 659 under certain conditions; type `show c' for details. | |
| 660 | |
| 661 The hypothetical commands `show w' and `show c' should show the appropriate | |
| 662 parts of the General Public License. Of course, your program's commands | |
| 663 might be different; for a GUI interface, you would use an "about box". | |
| 664 | |
| 665 You should also get your employer (if you work as a programmer) or school, | |
| 666 if any, to sign a "copyright disclaimer" for the program, if necessary. | |
| 667 For more information on this, and how to apply and follow the GNU GPL, see | |
| 668 <http://www.gnu.org/licenses/>. | |
| 669 | |
| 670 The GNU General Public License does not permit incorporating your program | |
| 671 into proprietary programs. If your program is a subroutine library, you | |
| 672 may consider it more useful to permit linking proprietary applications with | |
| 673 the library. If this is what you want to do, use the GNU Lesser General | |
| 674 Public License instead of this License. But first, please read | |
| 675 <http://www.gnu.org/philosophy/why-not-lgpl.html>. | |
