| 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 |
