193 restrictions on the recipients' exercise of the rights granted herein. 206 You may charge any price or no price for each copy that you convey,
194 You are not responsible for enforcing compliance by third parties to 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.
435
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
195 this License. 486 this License.
196 487
197 7. If, as a consequence of a court judgment or allegation of patent 488 Each contributor grants you a non-exclusive, worldwide, royalty-free
198 infringement or for any other reason (not limited to patent issues), 489 patent license under the contributor's essential patent claims, to
199 conditions are imposed on you (whether by court order, agreement or 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
200 otherwise) that contradict the conditions of this License, they do not 544 otherwise) that contradict the conditions of this License, they do not
201 excuse you from the conditions of this License. If you cannot 545 excuse you from the conditions of this License. If you cannot convey a
202 distribute so as to satisfy simultaneously your obligations under this 546 covered work so as to satisfy simultaneously your obligations under this
203 License and any other pertinent obligations, then as a consequence you 547 License and any other pertinent obligations, then as a consequence you may
204 may not distribute the Program at all. For example, if a patent 548 not convey it at all. For example, if you agree to terms that obligate you
205 license would not permit royalty-free redistribution of the Program by 549 to collect a royalty for further conveying from those to whom you convey
206 all those who receive copies directly or indirectly through you, then 550 the Program, the only way you could satisfy both those terms and this
207 the only way you could satisfy both it and this License would be to 551 License would be to refrain entirely from conveying the Program.
208 refrain entirely from distribution of the Program. 552
209 553 13. Use with the GNU Affero General Public License.

211 any particular circumstance, the balance of the section is intended to 555 Notwithstanding any other provision of this License, you have

223 to distribute software through any other system and a licensee cannot 567 the GNU General Public License from time to time. Such new versions will
224 impose that choice.
225
226 This section is intended to make thoroughly clear what is believed to
227 be a consequence of the rest of this License.
228
229 8. If the distribution and/or use of the Program is restricted in
230 certain countries either by patents or by copyrighted interfaces, the
231 original copyright holder who places the Program under this License
232 may add an explicit geographical distribution limitation excluding
233 those countries, so that distribution is permitted only in or among
234 countries not thus excluded. In such case, this License incorporates
235 the limitation as if written in the body of this License.
236
237 9. The Free Software Foundation may publish revised and/or new versions
238 of the General Public License from time to time. Such new versions will
239 be similar in spirit to the present version, but may differ in detail to 568 be similar in spirit to the present version, but may differ in detail to
240 address new problems or concerns. 569 address new problems or concerns.
241 570
242 Each version is given a distinguishing version number. If the Program 571 Each version is given a distinguishing version number. If the
243 specifies a version number of this License which applies to it and "any 572 Program specifies that a certain numbered version of the GNU General
244 later version", you have the option of following the terms and conditions 573 Public License "or any later version" applies to it, you have the
245 either of that version or of any later version published by the Free 574 option of following the terms and conditions either of that numbered
246 Software Foundation. If the Program does not specify a version number of 575 version or of any later version published by the Free Software
247 this License, you may choose any version ever published by the Free Software 576 Foundation. If the Program does not specify a version number of the
248 Foundation. 577 GNU General Public License, you may choose any version ever published
249 578 by the Free Software Foundation.
250 10. If you wish to incorporate parts of the Program into other free 579
251 programs whose distribution conditions are different, write to the author 580 If the Program specifies that a proxy can decide which future
252 to ask for permission. For software which is copyrighted by the Free 581 versions of the GNU General Public License can be used, that proxy's
253 Software Foundation, write to the Free Software Foundation; we sometimes 582 public statement of acceptance of a version permanently authorizes you

255 of preserving the free status of all derivatives of our free software and 584
256 of promoting the sharing and reuse of software generally. 585 Later license versions may give you additional or different
