| 3294 | 10 |
| 7016 | 11 Everyone is permitted to copy and distribute verbatim copies of this |
| 12 license document, but changing it is not allowed. | |
| 3294 | 13 @end display |
| 14 | |
| 7016 | 15 @heading Preamble |
| 16 | |
| 17 The GNU General Public License is a free, copyleft license for | |
| 18 software and other kinds of works. | |
| 3294 | 19 |
| 7016 | 20 The licenses for most software and other practical works are designed |
| 21 to take away your freedom to share and change the works. By contrast, | |
| 22 the GNU General Public License is intended to guarantee your freedom | |
| 23 to share and change all versions of a program---to make sure it remains | |
| 24 free software for all its users. We, the Free Software Foundation, | |
| 25 use the GNU General Public License for most of our software; it | |
| 26 applies also to any other work released this way by its authors. You | |
| 27 can apply it to your programs, too. | |
| 3294 | 28 |
| 7016 | 29 When we speak of free software, we are referring to freedom, not |
| 3294 | 30 price. Our General Public Licenses are designed to make sure that you |
| 31 have the freedom to distribute copies of free software (and charge for | |
| 7016 | 32 them if you wish), that you receive source code or can get it if you |
| 33 want it, that you can change the software or use pieces of it in new | |
| 34 free programs, and that you know you can do these things. | |
| 35 | |
| 36 To protect your rights, we need to prevent others from denying you | |
| 37 these rights or asking you to surrender the rights. Therefore, you | |
| 38 have certain responsibilities if you distribute copies of the | |
| 39 software, or if you modify it: responsibilities to respect the freedom | |
| 40 of others. | |
| 3294 | 41 |
| 7016 | 42 For example, if you distribute copies of such a program, whether |
| 43 gratis or for a fee, you must pass on to the recipients the same | |
| 44 freedoms that you received. You must make sure that they, too, | |
| 45 receive or can get the source code. And you must show them these | |
| 46 terms so they know their rights. | |
| 3294 | 47 |
| 7016 | 48 Developers that use the GNU GPL protect your rights with two steps: |
| 49 (1) assert copyright on the software, and (2) offer you this License | |
| 50 giving you legal permission to copy, distribute and/or modify it. | |
| 3294 | 51 |
| 7016 | 52 For the developers' and authors' protection, the GPL clearly explains |
| 53 that there is no warranty for this free software. For both users' and | |
| 54 authors' sake, the GPL requires that modified versions be marked as | |
| 55 changed, so that their problems will not be attributed erroneously to | |
| 56 authors of previous versions. | |
| 3294 | 57 |
| 7016 | 58 Some devices are designed to deny users access to install or run |
| 59 modified versions of the software inside them, although the | |
| 60 manufacturer can do so. This is fundamentally incompatible with the | |
| 61 aim of protecting users' freedom to change the software. The | |
| 62 systematic pattern of such abuse occurs in the area of products for | |
| 63 individuals to use, which is precisely where it is most unacceptable. | |
| 64 Therefore, we have designed this version of the GPL to prohibit the | |
| 65 practice for those products. If such problems arise substantially in | |
| 66 other domains, we stand ready to extend this provision to those | |
| 67 domains in future versions of the GPL, as needed to protect the | |
| 68 freedom of users. | |
| 3294 | 69 |
| 7016 | 70 Finally, every program is threatened constantly by software patents. |
| 71 States should not allow patents to restrict development and use of | |
| 72 software on general-purpose computers, but in those that do, we wish | |
| 73 to avoid the special danger that patents applied to a free program | |
| 74 could make it effectively proprietary. To prevent this, the GPL | |
| 75 assures that patents cannot be used to render the program non-free. | |
| 3294 | 76 |
| 7016 | 77 The precise terms and conditions for copying, distribution and |
| 3294 | 78 modification follow. |
| 79 | |
| 7016 | 80 @heading TERMS AND CONDITIONS |
| 3294 | 81 |
| 82 @enumerate 0 | |
| 7016 | 83 @item Definitions. |
| 84 | |
| 85 ``This License'' refers to version 3 of the GNU General Public License. | |
| 86 | |
| 87 ``Copyright'' also means copyright-like laws that apply to other kinds | |
| 88 of works, such as semiconductor masks. | |
| 89 | |
| 90 ``The Program'' refers to any copyrightable work licensed under this | |
| 91 License. Each licensee is addressed as ``you''. ``Licensees'' and | |
| 92 ``recipients'' may be individuals or organizations. | |
| 93 | |
| 94 To ``modify'' a work means to copy from or adapt all or part of the work | |
| 95 in a fashion requiring copyright permission, other than the making of | |
| 96 an exact copy. The resulting work is called a ``modified version'' of | |
| 97 the earlier work or a work ``based on'' the earlier work. | |
| 98 | |
| 99 A ``covered work'' means either the unmodified Program or a work based | |
| 100 on the Program. | |
| 101 | |
| 102 To ``propagate'' a work means to do anything with it that, without | |
| 103 permission, would make you directly or secondarily liable for | |
| 104 infringement under applicable copyright law, except executing it on a | |
| 105 computer or modifying a private copy. Propagation includes copying, | |
| 106 distribution (with or without modification), making available to the | |
| 107 public, and in some countries other activities as well. | |
| 108 | |
| 109 To ``convey'' a work means any kind of propagation that enables other | |
| 110 parties to make or receive copies. Mere interaction with a user | |
| 111 through a computer network, with no transfer of a copy, is not | |
| 112 conveying. | |
| 3294 | 113 |
| 7016 | 114 An interactive user interface displays ``Appropriate Legal Notices'' to |
| 115 the extent that it includes a convenient and prominently visible | |
| 116 feature that (1) displays an appropriate copyright notice, and (2) | |
| 117 tells the user that there is no warranty for the work (except to the | |
| 118 extent that warranties are provided), that licensees may convey the | |
| 119 work under this License, and how to view a copy of this License. If | |
| 120 the interface presents a list of user commands or options, such as a | |
| 121 menu, a prominent item in the list meets this criterion. | |
| 122 | |
| 123 @item Source Code. | |
| 124 | |
| 125 The ``source code'' for a work means the preferred form of the work for | |
| 126 making modifications to it. ``Object code'' means any non-source form | |
| 127 of a work. | |
| 128 | |
| 129 A ``Standard Interface'' means an interface that either is an official | |
| 130 standard defined by a recognized standards body, or, in the case of | |
| 131 interfaces specified for a particular programming language, one that | |
| 132 is widely used among developers working in that language. | |
| 133 | |
| 134 The ``System Libraries'' of an executable work include anything, other | |
| 135 than the work as a whole, that (a) is included in the normal form of | |
| 136 packaging a Major Component, but which is not part of that Major | |
| 137 Component, and (b) serves only to enable use of the work with that | |
| 138 Major Component, or to implement a Standard Interface for which an | |
| 139 implementation is available to the public in source code form. A | |
| 140 ``Major Component'', in this context, means a major essential component | |
| 141 (kernel, window system, and so on) of the specific operating system | |
| 142 (if any) on which the executable work runs, or a compiler used to | |
| 143 produce the work, or an object code interpreter used to run it. | |
| 3294 | 144 |
| 7016 | 145 The ``Corresponding Source'' for a work in object code form means all |
| 146 the source code needed to generate, install, and (for an executable | |
| 147 work) run the object code and to modify the work, including scripts to | |
| 148 control those activities. However, it does not include the work's | |
| 149 System Libraries, or general-purpose tools or generally available free | |
| 150 programs which are used unmodified in performing those activities but | |
| 151 which are not part of the work. For example, Corresponding Source | |
| 152 includes interface definition files associated with source files for | |
| 153 the work, and the source code for shared libraries and dynamically | |
| 154 linked subprograms that the work is specifically designed to require, | |
| 155 such as by intimate data communication or control flow between those | |
| 156 subprograms and other parts of the work. | |
| 157 | |
| 158 The Corresponding Source need not include anything that users can | |
| 159 regenerate automatically from other parts of the Corresponding Source. | |
| 160 | |
| 161 The Corresponding Source for a work in source code form is that same | |
| 162 work. | |
| 163 | |
| 164 @item Basic Permissions. | |
| 165 | |
| 166 All rights granted under this License are granted for the term of | |
| 167 copyright on the Program, and are irrevocable provided the stated | |
| 168 conditions are met. This License explicitly affirms your unlimited | |
| 169 permission to run the unmodified Program. The output from running a | |
| 170 covered work is covered by this License only if the output, given its | |
| 171 content, constitutes a covered work. This License acknowledges your | |
| 172 rights of fair use or other equivalent, as provided by copyright law. | |
| 173 | |
| 174 You may make, run and propagate covered works that you do not convey, | |
| 175 without conditions so long as your license otherwise remains in force. | |
| 176 You may convey covered works to others for the sole purpose of having | |
| 177 them make modifications exclusively for you, or provide you with | |
| 178 facilities for running those works, provided that you comply with the | |
| 179 terms of this License in conveying all material for which you do not | |
| 180 control copyright. Those thus making or running the covered works for | |
| 181 you must do so exclusively on your behalf, under your direction and | |
| 182 control, on terms that prohibit them from making any copies of your | |
| 183 copyrighted material outside their relationship with you. | |
| 3294 | 184 |
| 7016 | 185 Conveying under any other circumstances is permitted solely under the |
| 186 conditions stated below. Sublicensing is not allowed; section 10 | |
| 187 makes it unnecessary. | |
| 188 | |
| 189 @item Protecting Users' Legal Rights From Anti-Circumvention Law. | |
| 190 | |
| 191 No covered work shall be deemed part of an effective technological | |
| 192 measure under any applicable law fulfilling obligations under article | |
| 193 11 of the WIPO copyright treaty adopted on 20 December 1996, or | |
| 194 similar laws prohibiting or restricting circumvention of such | |
| 195 measures. | |
| 196 | |
| 197 When you convey a covered work, you waive any legal power to forbid | |
| 198 circumvention of technological measures to the extent such | |
| 199 circumvention is effected by exercising rights under this License with | |
| 200 respect to the covered work, and you disclaim any intention to limit | |
| 201 operation or modification of the work as a means of enforcing, against | |
| 202 the work's users, your or third parties' legal rights to forbid | |
| 203 circumvention of technological measures. | |
| 3294 | 204 |
| 7016 | 205 @item Conveying Verbatim Copies. |
| 206 | |
| 207 You may convey verbatim copies of the Program's source code as you | |
| 208 receive it, in any medium, provided that you conspicuously and | |
| 209 appropriately publish on each copy an appropriate copyright notice; | |
| 210 keep intact all notices stating that this License and any | |
| 211 non-permissive terms added in accord with section 7 apply to the code; | |
| 212 keep intact all notices of the absence of any warranty; and give all | |
| 213 recipients a copy of this License along with the Program. | |
| 214 | |
| 215 You may charge any price or no price for each copy that you convey, | |
| 216 and you may offer support or warranty protection for a fee. | |
| 217 | |
| 218 @item Conveying Modified Source Versions. | |
| 219 | |
| 220 You may convey a work based on the Program, or the modifications to | |
| 221 produce it from the Program, in the form of source code under the | |
| 222 terms of section 4, provided that you also meet all of these | |
| 223 conditions: | |

| 7016 | 227 The work must carry prominent notices stating that you modified it, |
| 228 and giving a relevant date. | |
| 3294 | 229 |
| 230 @item | |
| 7016 | 231 The work must carry prominent notices stating that it is released |
| 232 under this License and any conditions added under section 7. This | |
| 233 requirement modifies the requirement in section 4 to ``keep intact all | |
| 234 notices''. | |
| 3294 | 235 |
| 236 @item | |
| 7016 | 237 You must license the entire work, as a whole, under this License to |
| 238 anyone who comes into possession of a copy. This License will | |
| 239 therefore apply, along with any applicable section 7 additional terms, | |
| 240 to the whole of the work, and all its parts, regardless of how they | |
| 241 are packaged. This License gives no permission to license the work in | |
| 242 any other way, but it does not invalidate such permission if you have | |
| 243 separately received it. | |
| 244 | |
| 245 @item | |
| 246 If the work has interactive user interfaces, each must display | |
| 247 Appropriate Legal Notices; however, if the Program has interactive | |
| 248 interfaces that do not display Appropriate Legal Notices, your work | |
| 249 need not make them do so. | |

| 7016 | 252 A compilation of a covered work with other separate and independent |
| 253 works, which are not by their nature extensions of the covered work, | |
| 254 and which are not combined with it such as to form a larger program, | |
| 255 in or on a volume of a storage or distribution medium, is called an | |
| 256 ``aggregate'' if the compilation and its resulting copyright are not | |
| 257 used to limit the access or legal rights of the compilation's users | |
| 258 beyond what the individual works permit. Inclusion of a covered work | |
| 259 in an aggregate does not cause this License to apply to the other | |
| 260 parts of the aggregate. | |
| 3294 | 261 |
| 7016 | 262 @item Conveying Non-Source Forms. |
| 3294 | 263 |
| 7016 | 264 You may convey a covered work in object code form under the terms of |
| 265 sections 4 and 5, provided that you also convey the machine-readable | |
| 266 Corresponding Source under the terms of this License, in one of these | |
| 267 ways: | |
| 3294 | 268 |
| 269 @enumerate a | |
| 270 @item | |
| 7016 | 271 Convey the object code in, or embodied in, a physical product |
| 272 (including a physical distribution medium), accompanied by the | |
| 273 Corresponding Source fixed on a durable physical medium customarily | |
| 274 used for software interchange. | |
| 275 | |
| 276 @item | |
| 277 Convey the object code in, or embodied in, a physical product | |
| 278 (including a physical distribution medium), accompanied by a written | |
| 279 offer, valid for at least three years and valid for as long as you | |
| 280 offer spare parts or customer support for that product model, to give | |
| 281 anyone who possesses the object code either (1) a copy of the | |
| 282 Corresponding Source for all the software in the product that is | |
| 283 covered by this License, on a durable physical medium customarily used | |
| 284 for software interchange, for a price no more than your reasonable | |
| 285 cost of physically performing this conveying of source, or (2) access | |
| 286 to copy the Corresponding Source from a network server at no charge. | |
| 3294 | 287 |
| 288 @item | |
| 7016 | 289 Convey individual copies of the object code with a copy of the written |
| 290 offer to provide the Corresponding Source. This alternative is | |
| 291 allowed only occasionally and noncommercially, and only if you | |
| 292 received the object code with such an offer, in accord with subsection | |
| 293 6b. | |
| 3294 | 294 |
| 295 @item | |
| 7016 | 296 Convey the object code by offering access from a designated place |
| 297 (gratis or for a charge), and offer equivalent access to the | |
| 298 Corresponding Source in the same way through the same place at no | |
| 299 further charge. You need not require recipients to copy the | |
| 300 Corresponding Source along with the object code. If the place to copy | |
| 301 the object code is a network server, the Corresponding Source may be | |
| 302 on a different server (operated by you or a third party) that supports | |
| 303 equivalent copying facilities, provided you maintain clear directions | |
| 304 next to the object code saying where to find the Corresponding Source. | |
| 305 Regardless of what server hosts the Corresponding Source, you remain | |
| 306 obligated to ensure that it is available for as long as needed to | |
| 307 satisfy these requirements. | |
| 308 | |
| 309 @item | |
| 310 Convey the object code using peer-to-peer transmission, provided you | |
| 311 inform other peers where the object code and Corresponding Source of | |
| 312 the work are being offered to the general public at no charge under | |
| 313 subsection 6d. | |
| 314 | |
| 3294 | 315 @end enumerate |
| 316 | |
| 7016 | 317 A separable portion of the object code, whose source code is excluded |
| 318 from the Corresponding Source as a System Library, need not be | |
| 319 included in conveying the object code work. | |
| 320 | |
| 321 A ``User Product'' is either (1) a ``consumer product'', which means any | |
| 322 tangible personal property which is normally used for personal, | |
| 323 family, or household purposes, or (2) anything designed or sold for | |
| 324 incorporation into a dwelling. In determining whether a product is a | |
| 325 consumer product, doubtful cases shall be resolved in favor of | |
| 326 coverage. For a particular product received by a particular user, | |
| 327 ``normally used'' refers to a typical or common use of that class of | |
| 328 product, regardless of the status of the particular user or of the way | |
| 329 in which the particular user actually uses, or expects or is expected | |
| 330 to use, the product. A product is a consumer product regardless of | |
| 331 whether the product has substantial commercial, industrial or | |
| 332 non-consumer uses, unless such uses represent the only significant | |
| 333 mode of use of the product. | |
| 334 | |
| 335 ``Installation Information'' for a User Product means any methods, | |
| 336 procedures, authorization keys, or other information required to | |
| 337 install and execute modified versions of a covered work in that User | |
| 338 Product from a modified version of its Corresponding Source. The | |
| 339 information must suffice to ensure that the continued functioning of | |
| 340 the modified object code is in no case prevented or interfered with | |
| 341 solely because modification has been made. | |
| 342 | |
| 343 If you convey an object code work under this section in, or with, or | |
| 344 specifically for use in, a User Product, and the conveying occurs as | |
| 345 part of a transaction in which the right of possession and use of the | |
| 346 User Product is transferred to the recipient in perpetuity or for a | |
| 347 fixed term (regardless of how the transaction is characterized), the | |
| 348 Corresponding Source conveyed under this section must be accompanied | |
| 349 by the Installation Information. But this requirement does not apply | |
| 350 if neither you nor any third party retains the ability to install | |
| 351 modified object code on the User Product (for example, the work has | |
| 352 been installed in ROM). | |
| 3294 | 353 |
| 7016 | 354 The requirement to provide Installation Information does not include a |
| 355 requirement to continue to provide support service, warranty, or | |
| 356 updates for a work that has been modified or installed by the | |
| 357 recipient, or for the User Product in which it has been modified or | |
| 358 installed. Access to a network may be denied when the modification | |
| 359 itself materially and adversely affects the operation of the network | |
| 360 or violates the rules and protocols for communication across the | |
| 361 network. | |
| 362 | |
| 363 Corresponding Source conveyed, and Installation Information provided, | |
| 364 in accord with this section must be in a format that is publicly | |
| 365 documented (and with an implementation available to the public in | |
| 366 source code form), and must require no special password or key for | |
| 367 unpacking, reading or copying. | |
| 368 | |
| 369 @item Additional Terms. | |
| 370 | |
| 371 ``Additional permissions'' are terms that supplement the terms of this | |
| 372 License by making exceptions from one or more of its conditions. | |
| 373 Additional permissions that are applicable to the entire Program shall | |
| 374 be treated as though they were included in this License, to the extent | |
| 375 that they are valid under applicable law. If additional permissions | |
| 376 apply only to part of the Program, that part may be used separately | |
| 377 under those permissions, but the entire Program remains governed by | |
| 378 this License without regard to the additional permissions. | |
| 379 | |
| 380 When you convey a copy of a covered work, you may at your option | |
| 381 remove any additional permissions from that copy, or from any part of | |
| 382 it. (Additional permissions may be written to require their own | |
| 383 removal in certain cases when you modify the work.) You may place | |
| 384 additional permissions on material, added by you to a covered work, | |
| 385 for which you have or can give appropriate copyright permission. | |
| 386 | |
| 387 Notwithstanding any other provision of this License, for material you | |
| 388 add to a covered work, you may (if authorized by the copyright holders | |
| 389 of that material) supplement the terms of this License with terms: | |
| 390 | |
| 391 @enumerate a | |
| 392 @item | |
| 393 Disclaiming warranty or limiting liability differently from the terms | |
| 394 of sections 15 and 16 of this License; or | |
| 3294 | 395 |
| 396 @item | |
| 7016 | 397 Requiring preservation of specified reasonable legal notices or author |
| 398 attributions in that material or in the Appropriate Legal Notices | |
| 399 displayed by works containing it; or | |
| 3294 | 400 |
| 401 @item | |
| 7016 | 402 Prohibiting misrepresentation of the origin of that material, or |
| 403 requiring that modified versions of such material be marked in | |
| 404 reasonable ways as different from the original version; or | |
| 3294 | 405 |
| 406 @item | |
| 7016 | 407 Limiting the use for publicity purposes of names of licensors or |
| 408 authors of the material; or | |
| 409 | |
| 410 @item | |
| 411 Declining to grant rights under trademark law for use of some trade | |
| 412 names, trademarks, or service marks; or | |
| 3294 | 413 |

| 7016 | 415 Requiring indemnification of licensors and authors of that material by |
| 416 anyone who conveys the material (or modified versions of it) with | |
| 417 contractual assumptions of liability to the recipient, for any | |
| 418 liability that these contractual assumptions directly impose on those | |
| 419 licensors and authors. | |
| 420 @end enumerate | |
| 421 | |
| 422 All other non-permissive additional terms are considered ``further | |
| 423 restrictions'' within the meaning of section 10. If the Program as you | |
| 424 received it, or any part of it, contains a notice stating that it is | |
| 425 governed by this License along with a term that is a further | |
| 426 restriction, you may remove that term. If a license document contains | |
| 427 a further restriction but permits relicensing or conveying under this | |
| 428 License, you may add to a covered work material governed by the terms | |
| 429 of that license document, provided that the further restriction does | |
| 430 not survive such relicensing or conveying. | |
| 431 | |
| 432 If you add terms to a covered work in accord with this section, you | |
| 433 must place, in the relevant source files, a statement of the | |
| 434 additional terms that apply to those files, or a notice indicating | |
| 435 where to find the applicable terms. | |
| 436 | |
| 437 Additional terms, permissive or non-permissive, may be stated in the | |
| 438 form of a separately written license, or stated as exceptions; the | |
| 439 above requirements apply either way. | |
| 440 | |
| 441 @item Termination. | |
| 442 | |
| 443 You may not propagate or modify a covered work except as expressly | |
| 444 provided under this License. Any attempt otherwise to propagate or | |
| 445 modify it is void, and will automatically terminate your rights under | |
| 446 this License (including any patent licenses granted under the third | |
| 447 paragraph of section 11). | |
| 448 | |
| 449 However, if you cease all violation of this License, then your license | |
| 450 from a particular copyright holder is reinstated (a) provisionally, | |
| 451 unless and until the copyright holder explicitly and finally | |
| 452 terminates your license, and (b) permanently, if the copyright holder | |
| 453 fails to notify you of the violation by some reasonable means prior to | |
| 454 60 days after the cessation. | |
| 3294 | 455 |
| 7016 | 456 Moreover, your license from a particular copyright holder is |
| 457 reinstated permanently if the copyright holder notifies you of the | |
| 458 violation by some reasonable means, this is the first time you have | |
| 459 received notice of violation of this License (for any work) from that | |
| 460 copyright holder, and you cure the violation prior to 30 days after | |
| 461 your receipt of the notice. | |
| 462 | |
| 463 Termination of your rights under this section does not terminate the | |
| 464 licenses of parties who have received copies or rights from you under | |
| 465 this License. If your rights have been terminated and not permanently | |
| 466 reinstated, you do not qualify to receive new licenses for the same | |
| 467 material under section 10. | |
| 468 | |
| 469 @item Acceptance Not Required for Having Copies. | |
| 470 | |
| 471 You are not required to accept this License in order to receive or run | |
| 472 a copy of the Program. Ancillary propagation of a covered work | |
| 473 occurring solely as a consequence of using peer-to-peer transmission | |
| 474 to receive a copy likewise does not require acceptance. However, | |
| 475 nothing other than this License grants you permission to propagate or | |
| 476 modify any covered work. These actions infringe copyright if you do | |
| 477 not accept this License. Therefore, by modifying or propagating a | |
| 478 covered work, you indicate your acceptance of this License to do so. | |
| 479 | |
| 480 @item Automatic Licensing of Downstream Recipients. | |
| 481 | |
| 482 Each time you convey a covered work, the recipient automatically | |
| 483 receives a license from the original licensors, to run, modify and | |
| 484 propagate that work, subject to this License. You are not responsible | |
| 485 for enforcing compliance by third parties with this License. | |
| 486 | |
| 487 An ``entity transaction'' is a transaction transferring control of an | |
| 488 organization, or substantially all assets of one, or subdividing an | |
| 489 organization, or merging organizations. If propagation of a covered | |
| 490 work results from an entity transaction, each party to that | |
| 491 transaction who receives a copy of the work also receives whatever | |
| 492 licenses to the work the party's predecessor in interest had or could | |
| 493 give under the previous paragraph, plus a right to possession of the | |
| 494 Corresponding Source of the work from the predecessor in interest, if | |
| 495 the predecessor has it or can get it with reasonable efforts. | |
| 496 | |
| 497 You may not impose any further restrictions on the exercise of the | |
| 498 rights granted or affirmed under this License. For example, you may | |
| 499 not impose a license fee, royalty, or other charge for exercise of | |
| 500 rights granted under this License, and you may not initiate litigation | |
| 501 (including a cross-claim or counterclaim in a lawsuit) alleging that | |
| 502 any patent claim is infringed by making, using, selling, offering for | |
| 503 sale, or importing the Program or any portion of it. | |
| 504 | |
| 505 @item Patents. | |
| 3294 | 506 |
| 7016 | 507 A ``contributor'' is a copyright holder who authorizes use under this |
| 508 License of the Program or a work on which the Program is based. The | |
| 509 work thus licensed is called the contributor's ``contributor version''. | |
| 510 | |
| 511 A contributor's ``essential patent claims'' are all patent claims owned | |
| 512 or controlled by the contributor, whether already acquired or | |
| 513 hereafter acquired, that would be infringed by some manner, permitted | |
| 514 by this License, of making, using, or selling its contributor version, | |
| 515 but do not include claims that would be infringed only as a | |
| 516 consequence of further modification of the contributor version. For | |
| 517 purposes of this definition, ``control'' includes the right to grant | |
| 518 patent sublicenses in a manner consistent with the requirements of | |
| 519 this License. | |
| 520 | |
| 521 Each contributor grants you a non-exclusive, worldwide, royalty-free | |
| 522 patent license under the contributor's essential patent claims, to | |
| 523 make, use, sell, offer for sale, import and otherwise run, modify and | |
| 524 propagate the contents of its contributor version. | |
| 3294 | 525 |
| 7016 | 526 In the following three paragraphs, a ``patent license'' is any express |
| 527 agreement or commitment, however denominated, not to enforce a patent | |
| 528 (such as an express permission to practice a patent or covenant not to | |
| 529 sue for patent infringement). To ``grant'' such a patent license to a | |
| 530 party means to make such an agreement or commitment not to enforce a | |
| 531 patent against the party. | |
| 532 | |
| 533 If you convey a covered work, knowingly relying on a patent license, | |
| 534 and the Corresponding Source of the work is not available for anyone | |
| 535 to copy, free of charge and under the terms of this License, through a | |
| 536 publicly available network server or other readily accessible means, | |
| 537 then you must either (1) cause the Corresponding Source to be so | |
| 538 available, or (2) arrange to deprive yourself of the benefit of the | |
| 539 patent license for this particular work, or (3) arrange, in a manner | |
| 540 consistent with the requirements of this License, to extend the patent | |
| 541 license to downstream recipients. ``Knowingly relying'' means you have | |
| 542 actual knowledge that, but for the patent license, your conveying the | |
| 543 covered work in a country, or your recipient's use of the covered work | |
| 544 in a country, would infringe one or more identifiable patents in that | |
| 545 country that you have reason to believe are valid. | |
| 546 | |
| 547 If, pursuant to or in connection with a single transaction or | |
| 548 arrangement, you convey, or propagate by procuring conveyance of, a | |
| 549 covered work, and grant a patent license to some of the parties | |
| 550 receiving the covered work authorizing them to use, propagate, modify | |
| 551 or convey a specific copy of the covered work, then the patent license | |
| 552 you grant is automatically extended to all recipients of the covered | |
| 553 work and works based on it. | |
| 3294 | 554 |
| 7016 | 555 A patent license is ``discriminatory'' if it does not include within the |
| 556 scope of its coverage, prohibits the exercise of, or is conditioned on | |
| 557 the non-exercise of one or more of the rights that are specifically | |
| 558 granted under this License. You may not convey a covered work if you | |
| 559 are a party to an arrangement with a third party that is in the | |
| 560 business of distributing software, under which you make payment to the | |
| 561 third party based on the extent of your activity of conveying the | |
| 562 work, and under which the third party grants, to any of the parties | |
| 563 who would receive the covered work from you, a discriminatory patent | |
| 564 license (a) in connection with copies of the covered work conveyed by | |
| 565 you (or copies made from those copies), or (b) primarily for and in | |
| 566 connection with specific products or compilations that contain the | |
| 567 covered work, unless you entered into that arrangement, or that patent | |
| 568 license was granted, prior to 28 March 2007. | |
| 569 | |
| 570 Nothing in this License shall be construed as excluding or limiting | |
| 571 any implied license or other defenses to infringement that may | |
| 572 otherwise be available to you under applicable patent law. | |
| 573 | |
| 574 @item No Surrender of Others' Freedom. | |
| 3294 | 575 |
| 7016 | 576 If conditions are imposed on you (whether by court order, agreement or |
| 577 otherwise) that contradict the conditions of this License, they do not | |
| 578 excuse you from the conditions of this License. If you cannot convey | |
| 579 a covered work so as to satisfy simultaneously your obligations under | |
| 580 this License and any other pertinent obligations, then as a | |
| 581 consequence you may not convey it at all. For example, if you agree | |
| 582 to terms that obligate you to collect a royalty for further conveying | |
| 583 from those to whom you convey the Program, the only way you could | |
| 584 satisfy both those terms and this License would be to refrain entirely | |
| 585 from conveying the Program. | |
| 586 | |
| 587 @item Use with the GNU Affero General Public License. | |
| 588 | |
| 589 Notwithstanding any other provision of this License, you have | |
| 590 permission to link or combine any covered work with a work licensed | |
| 591 under version 3 of the GNU Affero General Public License into a single | |
| 592 combined work, and to convey the resulting work. The terms of this | |
| 593 License will continue to apply to the part which is the covered work, | |
| 594 but the special requirements of the GNU Affero General Public License, | |
| 595 section 13, concerning interaction through a network will apply to the | |
| 596 combination as such. | |
| 597 | |
| 598 @item Revised Versions of this License. | |
| 599 | |
| 3294 | 600 The Free Software Foundation may publish revised and/or new versions |
| 7016 | 601 of the GNU General Public License from time to time. Such new |
| 602 versions will be similar in spirit to the present version, but may | |
| 603 differ in detail to address new problems or concerns. | |
| 3294 | 604 |
| 605 Each version is given a distinguishing version number. If the Program | |
| 7016 | 606 specifies that a certain numbered version of the GNU General Public |
| 607 License ``or any later version'' applies to it, you have the option of | |
| 608 following the terms and conditions either of that numbered version or | |
| 609 of any later version published by the Free Software Foundation. If | |
| 610 the Program does not specify a version number of the GNU General | |
| 611 Public License, you may choose any version ever published by the Free | |
| 612 Software Foundation. | |
| 3294 | 613 |
| 7016 | 614 If the Program specifies that a proxy can decide which future versions |
| 615 of the GNU General Public License can be used, that proxy's public | |
| 616 statement of acceptance of a version permanently authorizes you to | |
| 617 choose that version for the Program. | |
| 618 | |
| 619 Later license versions may give you additional or different | |
| 620 permissions. However, no additional obligations are imposed on any | |
| 621 author or copyright holder as a result of your choosing to follow a | |
| 622 later version. | |
| 623 | |
| 624 @item Disclaimer of Warranty. | |
| 3294 | 625 |
| 7016 | 626 THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY |
| 627 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT | |
| 628 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM ``AS IS'' WITHOUT | |
| 629 WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT | |
| 630 LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR | |
| 631 A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND | |
| 632 PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE | |
| 633 DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR | |
| 634 CORRECTION. | |
| 635 | |
| 636 @item Limitation of Liability. | |
| 3294 | 637 |
| 7016 | 638 IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING |
| 639 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR | |
| 640 CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, | |
| 641 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES | |
| 642 ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT | |
| 643 NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR | |
| 644 LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM | |
| 645 TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER | |
| 646 PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. | |
| 3294 | 647 |
| 7016 | 648 @item Interpretation of Sections 15 and 16. |
| 649 | |
| 650 If the disclaimer of warranty and limitation of liability provided | |
| 651 above cannot be given local legal effect according to their terms, | |
| 652 reviewing courts shall apply local law that most closely approximates | |
| 653 an absolute waiver of all civil liability in connection with the | |
| 654 Program, unless a warranty or assumption of liability accompanies a | |
| 655 copy of the Program in return for a fee. | |

| 661 @heading How to Apply These Terms to Your New Programs | |
| 3294 | 662 |
| 7016 | 663 If you develop a new program, and you want it to be of the greatest |
| 3294 | 664 possible use to the public, the best way to achieve this is to make it |
| 7016 | 665 free software which everyone can redistribute and change under these |
| 666 terms. | |
| 3294 | 667 |
| 7016 | 668 To do so, attach the following notices to the program. It is safest |
| 3294 | 669 to attach them to the start of each source file to most effectively |
| 7016 | 670 state the exclusion of warranty; and each file should have at least |
| 3294 | 671 the ``copyright'' line and a pointer to where the full notice is found. |

| 7016 | 713 The GNU General Public License does not permit incorporating your |
