30 These restrictions translate to certain responsibilities for you if you 31 certain responsibilities if you distribute copies of the software, or if

63 software on general-purpose computers, but in those that do, we wish to

193 restrictions on the recipients' exercise of the rights granted herein. 205 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 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
195 this License. 485 this License.
196 486
197 7. If, as a consequence of a court judgment or allegation of patent 487 Each contributor grants you a non-exclusive, worldwide, royalty-free
198 infringement or for any other reason (not limited to patent issues), 488 patent license under the contributor's essential patent claims, to
199 conditions are imposed on you (whether by court order, agreement or 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
200 otherwise) that contradict the conditions of this License, they do not 543 otherwise) that contradict the conditions of this License, they do not
201 excuse you from the conditions of this License. If you cannot 544 excuse you from the conditions of this License. If you cannot convey a
202 distribute so as to satisfy simultaneously your obligations under this 545 covered work so as to satisfy simultaneously your obligations under this
203 License and any other pertinent obligations, then as a consequence you 546 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 547 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 548 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 549 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 550 License would be to refrain entirely from conveying the Program.
208 refrain entirely from distribution of the Program. 551
209 552 13. Use with the GNU Affero General Public License.

211 any particular circumstance, the balance of the section is intended to 554 Notwithstanding any other provision of this License, you have

223 to distribute software through any other system and a licensee cannot 566 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 567 be similar in spirit to the present version, but may differ in detail to
240 address new problems or concerns. 568 address new problems or concerns.
241 569
242 Each version is given a distinguishing version number. If the Program 570 Each version is given a distinguishing version number. If the
243 specifies a version number of this License which applies to it and "any 571 Program specifies that a certain numbered version of the GNU General
244 later version", you have the option of following the terms and conditions 572 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 573 option of following the terms and conditions either of that numbered
246 Software Foundation. If the Program does not specify a version number of 574 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 575 Foundation. If the Program does not specify a version number of the
248 Foundation. 576 GNU General Public License, you may choose any version ever published
249 577 by the Free Software Foundation.
250 10. If you wish to incorporate parts of the Program into other free 578
251 programs whose distribution conditions are different, write to the author 579 If the Program specifies that a proxy can decide which future
252 to ask for permission. For software which is copyrighted by the Free 580 versions of the GNU General Public License can be used, that proxy's
253 Software Foundation, write to the Free Software Foundation; we sometimes 581 public statement of acceptance of a version permanently authorizes you
254 make exceptions for this. Our decision will be guided by the two goals 582 to choose that version for the Program.
255 of preserving the free status of all derivatives of our free software and 583
256 of promoting the sharing and reuse of software generally. 584 Later license versions may give you additional or different
257 585 permissions. However, no additional obligations are imposed on any
