14 <p style="text-align: center;">Version 3, 29 June 2007</p>
15
16 <p>Copyright &copy; 2007 Free Software Foundation, Inc.
17 &lt;<a href="https://fsf.org/">https://fsf.org/</a>&gt;</p><p>
18 Everyone is permitted to copy and distribute verbatim copies
19 of this license document, but changing it is not allowed.</p>
20
21 <h3><a name="preamble"></a>Preamble</h3>
22
23 <p>The GNU General Public License is a free, copyleft license for
24 software and other kinds of works.</p>
25
26 <p>The licenses for most software and other practical works are designed
27 to take away your freedom to share and change the works. By contrast,
28 the GNU General Public License is intended to guarantee your freedom to
29 share and change all versions of a program--to make sure it remains free
30 software for all its users. We, the Free Software Foundation, use the
31 GNU General Public License for most of our software; it applies also to
32 any other work released this way by its authors. You can apply it to
33 your programs, too.</p>
34
35 <p>When we speak of free software, we are referring to freedom, not
36 price. Our General Public Licenses are designed to make sure that you
37 have the freedom to distribute copies of free software (and charge for
38 them if you wish), that you receive source code or can get it if you
39 want it, that you can change the software or use pieces of it in new
40 free programs, and that you know you can do these things.</p>
41
42 <p>To protect your rights, we need to prevent others from denying you
43 these rights or asking you to surrender the rights. Therefore, you have
44 certain responsibilities if you distribute copies of the software, or if
45 you modify it: responsibilities to respect the freedom of others.</p>
46
47 <p>For example, if you distribute copies of such a program, whether
48 gratis or for a fee, you must pass on to the recipients the same
49 freedoms that you received. You must make sure that they, too, receive
50 or can get the source code. And you must show them these terms so they
51 know their rights.</p>
52
53 <p>Developers that use the GNU GPL protect your rights with two steps:
54 (1) assert copyright on the software, and (2) offer you this License
55 giving you legal permission to copy, distribute and/or modify it.</p>
56
57 <p>For the developers' and authors' protection, the GPL clearly explains
58 that there is no warranty for this free software. For both users' and
59 authors' sake, the GPL requires that modified versions be marked as
60 changed, so that their problems will not be attributed erroneously to
61 authors of previous versions.</p>
62
63 <p>Some devices are designed to deny users access to install or run
64 modified versions of the software inside them, although the manufacturer
65 can do so. This is fundamentally incompatible with the aim of
66 protecting users' freedom to change the software. The systematic
67 pattern of such abuse occurs in the area of products for individuals to
68 use, which is precisely where it is most unacceptable. Therefore, we
69 have designed this version of the GPL to prohibit the practice for those
70 products. If such problems arise substantially in other domains, we
71 stand ready to extend this provision to those domains in future versions
72 of the GPL, as needed to protect the freedom of users.</p>
73
74 <p>Finally, every program is threatened constantly by software patents.
75 States should not allow patents to restrict development and use of
76 software on general-purpose computers, but in those that do, we wish to
77 avoid the special danger that patents applied to a free program could
78 make it effectively proprietary. To prevent this, the GPL assures that
79 patents cannot be used to render the program non-free.</p>
80
81 <p>The precise terms and conditions for copying, distribution and
82 modification follow.</p>
83
84 <h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
85
86 <h4><a name="section0"></a>0. Definitions.</h4>
87
88 <p>&ldquo;This License&rdquo; refers to version 3 of the GNU General Public License.</p>
89
90 <p>&ldquo;Copyright&rdquo; also means copyright-like laws that apply to other kinds of
91 works, such as semiconductor masks.</p>
92
93 <p>&ldquo;The Program&rdquo; refers to any copyrightable work licensed under this
94 License. Each licensee is addressed as &ldquo;you&rdquo;. &ldquo;Licensees&rdquo; and
95 &ldquo;recipients&rdquo; may be individuals or organizations.</p>
96
97 <p>To &ldquo;modify&rdquo; a work means to copy from or adapt all or part of the work
98 in a fashion requiring copyright permission, other than the making of an
99 exact copy. The resulting work is called a &ldquo;modified version&rdquo; of the
100 earlier work or a work &ldquo;based on&rdquo; the earlier work.</p>
101
102 <p>A &ldquo;covered work&rdquo; means either the unmodified Program or a work based
103 on the Program.</p>
104
105 <p>To &ldquo;propagate&rdquo; a work means to do anything with it that, without
106 permission, would make you directly or secondarily liable for
107 infringement under applicable copyright law, except executing it on a
108 computer or modifying a private copy. Propagation includes copying,
109 distribution (with or without modification), making available to the
110 public, and in some countries other activities as well.</p>
111
112 <p>To &ldquo;convey&rdquo; a work means any kind of propagation that enables other
113 parties to make or receive copies. Mere interaction with a user through
114 a computer network, with no transfer of a copy, is not conveying.</p>
115
116 <p>An interactive user interface displays &ldquo;Appropriate Legal Notices&rdquo;
117 to the extent that it includes a convenient and prominently visible
118 feature that (1) displays an appropriate copyright notice, and (2)
119 tells the user that there is no warranty for the work (except to the
120 extent that warranties are provided), that licensees may convey the
121 work under this License, and how to view a copy of this License. If
122 the interface presents a list of user commands or options, such as a
123 menu, a prominent item in the list meets this criterion.</p>
124
125 <h4><a name="section1"></a>1. Source Code.</h4>
126
127 <p>The &ldquo;source code&rdquo; for a work means the preferred form of the work
128 for making modifications to it. &ldquo;Object code&rdquo; means any non-source
129 form of a work.</p>
130
131 <p>A &ldquo;Standard Interface&rdquo; means an interface that either is an official
132 standard defined by a recognized standards body, or, in the case of
133 interfaces specified for a particular programming language, one that
134 is widely used among developers working in that language.</p>
135
136 <p>The &ldquo;System Libraries&rdquo; of an executable work include anything, other
137 than the work as a whole, that (a) is included in the normal form of
138 packaging a Major Component, but which is not part of that Major
139 Component, and (b) serves only to enable use of the work with that
140 Major Component, or to implement a Standard Interface for which an
141 implementation is available to the public in source code form. A
142 &ldquo;Major Component&rdquo;, in this context, means a major essential component
143 (kernel, window system, and so on) of the specific operating system
144 (if any) on which the executable work runs, or a compiler used to
145 produce the work, or an object code interpreter used to run it.</p>
146
147 <p>The &ldquo;Corresponding Source&rdquo; for a work in object code form means all
148 the source code needed to generate, install, and (for an executable
149 work) run the object code and to modify the work, including scripts to
150 control those activities. However, it does not include the work's
151 System Libraries, or general-purpose tools or generally available free
152 programs which are used unmodified in performing those activities but
153 which are not part of the work. For example, Corresponding Source
154 includes interface definition files associated with source files for
155 the work, and the source code for shared libraries and dynamically
156 linked subprograms that the work is specifically designed to require,
157 such as by intimate data communication or control flow between those
158 subprograms and other parts of the work.</p>
159
160 <p>The Corresponding Source need not include anything that users
161 can regenerate automatically from other parts of the Corresponding
162 Source.</p>
163
164 <p>The Corresponding Source for a work in source code form is that
165 same work.</p>
166
167 <h4><a name="section2"></a>2. Basic Permissions.</h4>
168
169 <p>All rights granted under this License are granted for the term of
170 copyright on the Program, and are irrevocable provided the stated
171 conditions are met. This License explicitly affirms your unlimited
172 permission to run the unmodified Program. The output from running a
173 covered work is covered by this License only if the output, given its
174 content, constitutes a covered work. This License acknowledges your
175 rights of fair use or other equivalent, as provided by copyright law.</p>
176
177 <p>You may make, run and propagate covered works that you do not
178 convey, without conditions so long as your license otherwise remains
179 in force. You may convey covered works to others for the sole purpose
180 of having them make modifications exclusively for you, or provide you
181 with facilities for running those works, provided that you comply with
182 the terms of this License in conveying all material for which you do
183 not control copyright. Those thus making or running the covered works
184 for you must do so exclusively on your behalf, under your direction
185 and control, on terms that prohibit them from making any copies of
186 your copyrighted material outside their relationship with you.</p>
187
188 <p>Conveying under any other circumstances is permitted solely under
189 the conditions stated below. Sublicensing is not allowed; section 10
190 makes it unnecessary.</p>
191
192 <h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
193
194 <p>No covered work shall be deemed part of an effective technological
195 measure under any applicable law fulfilling obligations under article
196 11 of the WIPO copyright treaty adopted on 20 December 1996, or
197 similar laws prohibiting or restricting circumvention of such
198 measures.</p>
199
200 <p>When you convey a covered work, you waive any legal power to forbid
201 circumvention of technological measures to the extent such circumvention
202 is effected by exercising rights under this License with respect to
203 the covered work, and you disclaim any intention to limit operation or
204 modification of the work as a means of enforcing, against the work's
205 users, your or third parties' legal rights to forbid circumvention of
206 technological measures.</p>
207
208 <h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
209
210 <p>You may convey verbatim copies of the Program's source code as you
211 receive it, in any medium, provided that you conspicuously and
212 appropriately publish on each copy an appropriate copyright notice;
213 keep intact all notices stating that this License and any
214 non-permissive terms added in accord with section 7 apply to the code;
215 keep intact all notices of the absence of any warranty; and give all
216 recipients a copy of this License along with the Program.</p>
217
218 <p>You may charge any price or no price for each copy that you convey,
219 and you may offer support or warranty protection for a fee.</p>
220
221 <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
222
223 <p>You may convey a work based on the Program, or the modifications to
224 produce it from the Program, in the form of source code under the
225 terms of section 4, provided that you also meet all of these conditions:</p>
226
227 <ul>
228 <li>a) The work must carry prominent notices stating that you modified
229 it, and giving a relevant date.</li>
230
231 <li>b) The work must carry prominent notices stating that it is
232 released under this License and any conditions added under section
233 7. This requirement modifies the requirement in section 4 to
234 &ldquo;keep intact all notices&rdquo;.</li>
235
236 <li>c) You must license the entire work, as a whole, under this
237 License to anyone who comes into possession of a copy. This
238 License will therefore apply, along with any applicable section 7
239 additional terms, to the whole of the work, and all its parts,
240 regardless of how they are packaged. This License gives no
241 permission to license the work in any other way, but it does not
242 invalidate such permission if you have separately received it.</li>
243
244 <li>d) If the work has interactive user interfaces, each must display
245 Appropriate Legal Notices; however, if the Program has interactive
246 interfaces that do not display Appropriate Legal Notices, your
247 work need not make them do so.</li>
248 </ul>
249
250 <p>A compilation of a covered work with other separate and independent
251 works, which are not by their nature extensions of the covered work,
252 and which are not combined with it such as to form a larger program,
253 in or on a volume of a storage or distribution medium, is called an
254 &ldquo;aggregate&rdquo; if the compilation and its resulting copyright are not
255 used to limit the access or legal rights of the compilation's users
256 beyond what the individual works permit. Inclusion of a covered work
257 in an aggregate does not cause this License to apply to the other
258 parts of the aggregate.</p>
259
260 <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
261
262 <p>You may convey a covered work in object code form under the terms
263 of sections 4 and 5, provided that you also convey the
264 machine-readable Corresponding Source under the terms of this License,
265 in one of these ways:</p>
266
267 <ul>
268 <li>a) Convey the object code in, or embodied in, a physical product
269 (including a physical distribution medium), accompanied by the
270 Corresponding Source fixed on a durable physical medium
271 customarily used for software interchange.</li>
272
273 <li>b) Convey the object code in, or embodied in, a physical product
274 (including a physical distribution medium), accompanied by a
275 written offer, valid for at least three years and valid for as
276 long as you offer spare parts or customer support for that product
277 model, to give anyone who possesses the object code either (1) a
278 copy of the Corresponding Source for all the software in the
279 product that is covered by this License, on a durable physical
280 medium customarily used for software interchange, for a price no
281 more than your reasonable cost of physically performing this
282 conveying of source, or (2) access to copy the
283 Corresponding Source from a network server at no charge.</li>
284
285 <li>c) Convey individual copies of the object code with a copy of the
286 written offer to provide the Corresponding Source. This
287 alternative is allowed only occasionally and noncommercially, and
288 only if you received the object code with such an offer, in accord
289 with subsection 6b.</li>
290
291 <li>d) Convey the object code by offering access from a designated
292 place (gratis or for a charge), and offer equivalent access to the
293 Corresponding Source in the same way through the same place at no
294 further charge. You need not require recipients to copy the
295 Corresponding Source along with the object code. If the place to
296 copy the object code is a network server, the Corresponding Source
297 may be on a different server (operated by you or a third party)
298 that supports equivalent copying facilities, provided you maintain
299 clear directions next to the object code saying where to find the
300 Corresponding Source. Regardless of what server hosts the
301 Corresponding Source, you remain obligated to ensure that it is
302 available for as long as needed to satisfy these requirements.</li>
303
304 <li>e) Convey the object code using peer-to-peer transmission, provided
305 you inform other peers where the object code and Corresponding
306 Source of the work are being offered to the general public at no
307 charge under subsection 6d.</li>
308 </ul>
309
310 <p>A separable portion of the object code, whose source code is excluded
311 from the Corresponding Source as a System Library, need not be
312 included in conveying the object code work.</p>
313
314 <p>A &ldquo;User Product&rdquo; is either (1) a &ldquo;consumer product&rdquo;, which means any
315 tangible personal property which is normally used for personal, family,
316 or household purposes, or (2) anything designed or sold for incorporation
317 into a dwelling. In determining whether a product is a consumer product,
318 doubtful cases shall be resolved in favor of coverage. For a particular
319 product received by a particular user, &ldquo;normally used&rdquo; refers to a
320 typical or common use of that class of product, regardless of the status
321 of the particular user or of the way in which the particular user
322 actually uses, or expects or is expected to use, the product. A product
323 is a consumer product regardless of whether the product has substantial
324 commercial, industrial or non-consumer uses, unless such uses represent
325 the only significant mode of use of the product.</p>
326
327 <p>&ldquo;Installation Information&rdquo; for a User Product means any methods,
328 procedures, authorization keys, or other information required to install
329 and execute modified versions of a covered work in that User Product from
330 a modified version of its Corresponding Source. The information must
331 suffice to ensure that the continued functioning of the modified object
332 code is in no case prevented or interfered with solely because
333 modification has been made.</p>
334
335 <p>If you convey an object code work under this section in, or with, or
336 specifically for use in, a User Product, and the conveying occurs as
337 part of a transaction in which the right of possession and use of the
338 User Product is transferred to the recipient in perpetuity or for a
339 fixed term (regardless of how the transaction is characterized), the
340 Corresponding Source conveyed under this section must be accompanied
341 by the Installation Information. But this requirement does not apply
342 if neither you nor any third party retains the ability to install
343 modified object code on the User Product (for example, the work has
344 been installed in ROM).</p>
345
346 <p>The requirement to provide Installation Information does not include a
347 requirement to continue to provide support service, warranty, or updates
348 for a work that has been modified or installed by the recipient, or for
349 the User Product in which it has been modified or installed. Access to a
350 network may be denied when the modification itself materially and
351 adversely affects the operation of the network or violates the rules and
352 protocols for communication across the network.</p>
353
354 <p>Corresponding Source conveyed, and Installation Information provided,
355 in accord with this section must be in a format that is publicly
356 documented (and with an implementation available to the public in
357 source code form), and must require no special password or key for
358 unpacking, reading or copying.</p>
359
360 <h4><a name="section7"></a>7. Additional Terms.</h4>
361
362 <p>&ldquo;Additional permissions&rdquo; are terms that supplement the terms of this
363 License by making exceptions from one or more of its conditions.
364 Additional permissions that are applicable to the entire Program shall
365 be treated as though they were included in this License, to the extent
366 that they are valid under applicable law. If additional permissions
367 apply only to part of the Program, that part may be used separately
368 under those permissions, but the entire Program remains governed by
369 this License without regard to the additional permissions.</p>
370
371 <p>When you convey a copy of a covered work, you may at your option
372 remove any additional permissions from that copy, or from any part of
373 it. (Additional permissions may be written to require their own
374 removal in certain cases when you modify the work.) You may place
375 additional permissions on material, added by you to a covered work,
376 for which you have or can give appropriate copyright permission.</p>
377
378 <p>Notwithstanding any other provision of this License, for material you
379 add to a covered work, you may (if authorized by the copyright holders of
380 that material) supplement the terms of this License with terms:</p>
381
382 <ul>
383 <li>a) Disclaiming warranty or limiting liability differently from the
384 terms of sections 15 and 16 of this License; or</li>
385
386 <li>b) Requiring preservation of specified reasonable legal notices or
387 author attributions in that material or in the Appropriate Legal
388 Notices displayed by works containing it; or</li>
389
390 <li>c) Prohibiting misrepresentation of the origin of that material, or
391 requiring that modified versions of such material be marked in
392 reasonable ways as different from the original version; or</li>
393
394 <li>d) Limiting the use for publicity purposes of names of licensors or
395 authors of the material; or</li>
396
397 <li>e) Declining to grant rights under trademark law for use of some
398 trade names, trademarks, or service marks; or</li>
399
400 <li>f) Requiring indemnification of licensors and authors of that
401 material by anyone who conveys the material (or modified versions of
402 it) with contractual assumptions of liability to the recipient, for
403 any liability that these contractual assumptions directly impose on
404 those licensors and authors.</li>
405 </ul>
406
407 <p>All other non-permissive additional terms are considered &ldquo;further
408 restrictions&rdquo; within the meaning of section 10. If the Program as you
409 received it, or any part of it, contains a notice stating that it is
410 governed by this License along with a term that is a further
411 restriction, you may remove that term. If a license document contains
412 a further restriction but permits relicensing or conveying under this
413 License, you may add to a covered work material governed by the terms
414 of that license document, provided that the further restriction does
415 not survive such relicensing or conveying.</p>
416
417 <p>If you add terms to a covered work in accord with this section, you
418 must place, in the relevant source files, a statement of the
419 additional terms that apply to those files, or a notice indicating
420 where to find the applicable terms.</p>
421
422 <p>Additional terms, permissive or non-permissive, may be stated in the
423 form of a separately written license, or stated as exceptions;
424 the above requirements apply either way.</p>
425
426 <h4><a name="section8"></a>8. Termination.</h4>
427
428 <p>You may not propagate or modify a covered work except as expressly
429 provided under this License. Any attempt otherwise to propagate or
430 modify it is void, and will automatically terminate your rights under
431 this License (including any patent licenses granted under the third
432 paragraph of section 11).</p>
433
434 <p>However, if you cease all violation of this License, then your
435 license from a particular copyright holder is reinstated (a)
436 provisionally, unless and until the copyright holder explicitly and
437 finally terminates your license, and (b) permanently, if the copyright
438 holder fails to notify you of the violation by some reasonable means
439 prior to 60 days after the cessation.</p>
440
441 <p>Moreover, your license from a particular copyright holder is
442 reinstated permanently if the copyright holder notifies you of the
443 violation by some reasonable means, this is the first time you have
444 received notice of violation of this License (for any work) from that
445 copyright holder, and you cure the violation prior to 30 days after
446 your receipt of the notice.</p>
447
448 <p>Termination of your rights under this section does not terminate the
449 licenses of parties who have received copies or rights from you under
450 this License. If your rights have been terminated and not permanently
451 reinstated, you do not qualify to receive new licenses for the same
452 material under section 10.</p>
453
454 <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
455
456 <p>You are not required to accept this License in order to receive or
457 run a copy of the Program. Ancillary propagation of a covered work
458 occurring solely as a consequence of using peer-to-peer transmission
459 to receive a copy likewise does not require acceptance. However,
460 nothing other than this License grants you permission to propagate or
461 modify any covered work. These actions infringe copyright if you do
462 not accept this License. Therefore, by modifying or propagating a
463 covered work, you indicate your acceptance of this License to do so.</p>
464
465 <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
466
467 <p>Each time you convey a covered work, the recipient automatically
468 receives a license from the original licensors, to run, modify and
469 propagate that work, subject to this License. You are not responsible
470 for enforcing compliance by third parties with this License.</p>
471
472 <p>An &ldquo;entity transaction&rdquo; is a transaction transferring control of an
473 organization, or substantially all assets of one, or subdividing an
474 organization, or merging organizations. If propagation of a covered
475 work results from an entity transaction, each party to that
476 transaction who receives a copy of the work also receives whatever
477 licenses to the work the party's predecessor in interest had or could
478 give under the previous paragraph, plus a right to possession of the
479 Corresponding Source of the work from the predecessor in interest, if
480 the predecessor has it or can get it with reasonable efforts.</p>
481
482 <p>You may not impose any further restrictions on the exercise of the
483 rights granted or affirmed under this License. For example, you may
484 not impose a license fee, royalty, or other charge for exercise of
485 rights granted under this License, and you may not initiate litigation
486 (including a cross-claim or counterclaim in a lawsuit) alleging that
487 any patent claim is infringed by making, using, selling, offering for
488 sale, or importing the Program or any portion of it.</p>
489
490 <h4><a name="section11"></a>11. Patents.</h4>
491
492 <p>A &ldquo;contributor&rdquo; is a copyright holder who authorizes use under this
493 License of the Program or a work on which the Program is based. The
494 work thus licensed is called the contributor's &ldquo;contributor version&rdquo;.</p>
495
496 <p>A contributor's &ldquo;essential patent claims&rdquo; are all patent claims
497 owned or controlled by the contributor, whether already acquired or
498 hereafter acquired, that would be infringed by some manner, permitted
499 by this License, of making, using, or selling its contributor version,
500 but do not include claims that would be infringed only as a
501 consequence of further modification of the contributor version. For
502 purposes of this definition, &ldquo;control&rdquo; includes the right to grant
503 patent sublicenses in a manner consistent with the requirements of
504 this License.</p>
505
506 <p>Each contributor grants you a non-exclusive, worldwide, royalty-free
507 patent license under the contributor's essential patent claims, to
508 make, use, sell, offer for sale, import and otherwise run, modify and
509 propagate the contents of its contributor version.</p>
510
511 <p>In the following three paragraphs, a &ldquo;patent license&rdquo; is any express
512 agreement or commitment, however denominated, not to enforce a patent
513 (such as an express permission to practice a patent or covenant not to
514 sue for patent infringement). To &ldquo;grant&rdquo; such a patent license to a
515 party means to make such an agreement or commitment not to enforce a
516 patent against the party.</p>
517
518 <p>If you convey a covered work, knowingly relying on a patent license,
519 and the Corresponding Source of the work is not available for anyone
520 to copy, free of charge and under the terms of this License, through a
521 publicly available network server or other readily accessible means,
522 then you must either (1) cause the Corresponding Source to be so
523 available, or (2) arrange to deprive yourself of the benefit of the
524 patent license for this particular work, or (3) arrange, in a manner
525 consistent with the requirements of this License, to extend the patent
526 license to downstream recipients. &ldquo;Knowingly relying&rdquo; means you have
527 actual knowledge that, but for the patent license, your conveying the
528 covered work in a country, or your recipient's use of the covered work
529 in a country, would infringe one or more identifiable patents in that
530 country that you have reason to believe are valid.</p>
531
532 <p>If, pursuant to or in connection with a single transaction or
533 arrangement, you convey, or propagate by procuring conveyance of, a
534 covered work, and grant a patent license to some of the parties
535 receiving the covered work authorizing them to use, propagate, modify
536 or convey a specific copy of the covered work, then the patent license
537 you grant is automatically extended to all recipients of the covered
538 work and works based on it.</p>
539
540 <p>A patent license is &ldquo;discriminatory&rdquo; if it does not include within
541 the scope of its coverage, prohibits the exercise of, or is
542 conditioned on the non-exercise of one or more of the rights that are
543 specifically granted under this License. You may not convey a covered
544 work if you are a party to an arrangement with a third party that is
545 in the business of distributing software, under which you make payment
546 to the third party based on the extent of your activity of conveying
547 the work, and under which the third party grants, to any of the
548 parties who would receive the covered work from you, a discriminatory
549 patent license (a) in connection with copies of the covered work
550 conveyed by you (or copies made from those copies), or (b) primarily
551 for and in connection with specific products or compilations that
552 contain the covered work, unless you entered into that arrangement,
553 or that patent license was granted, prior to 28 March 2007.</p>
554
555 <p>Nothing in this License shall be construed as excluding or limiting
556 any implied license or other defenses to infringement that may
557 otherwise be available to you under applicable patent law.</p>
558
559 <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
560
561 <p>If conditions are imposed on you (whether by court order, agreement or
562 otherwise) that contradict the conditions of this License, they do not
563 excuse you from the conditions of this License. If you cannot convey a
564 covered work so as to satisfy simultaneously your obligations under this
565 License and any other pertinent obligations, then as a consequence you may
566 not convey it at all. For example, if you agree to terms that obligate you
567 to collect a royalty for further conveying from those to whom you convey
568 the Program, the only way you could satisfy both those terms and this
569 License would be to refrain entirely from conveying the Program.</p>
570
571 <h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
572
573 <p>Notwithstanding any other provision of this License, you have
574 permission to link or combine any covered work with a work licensed
575 under version 3 of the GNU Affero General Public License into a single
576 combined work, and to convey the resulting work. The terms of this
577 License will continue to apply to the part which is the covered work,
578 but the special requirements of the GNU Affero General Public License,
579 section 13, concerning interaction through a network will apply to the
580 combination as such.</p>
581
582 <h4><a name="section14"></a>14. Revised Versions of this License.</h4>
583
584 <p>The Free Software Foundation may publish revised and/or new versions of
585 the GNU General Public License from time to time. Such new versions will
586 be similar in spirit to the present version, but may differ in detail to
587 address new problems or concerns.</p>
588
589 <p>Each version is given a distinguishing version number. If the
590 Program specifies that a certain numbered version of the GNU General
591 Public License &ldquo;or any later version&rdquo; applies to it, you have the
592 option of following the terms and conditions either of that numbered
593 version or of any later version published by the Free Software
594 Foundation. If the Program does not specify a version number of the
595 GNU General Public License, you may choose any version ever published
596 by the Free Software Foundation.</p>
597
598 <p>If the Program specifies that a proxy can decide which future
599 versions of the GNU General Public License can be used, that proxy's
600 public statement of acceptance of a version permanently authorizes you
601 to choose that version for the Program.</p>
602
603 <p>Later license versions may give you additional or different
604 permissions. However, no additional obligations are imposed on any
605 author or copyright holder as a result of your choosing to follow a
606 later version.</p>
607
608 <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
609
610 <p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
611 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
612 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM &ldquo;AS IS&rdquo; WITHOUT WARRANTY
613 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
614 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
615 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
616 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
617 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
618
619 <h4><a name="section16"></a>16. Limitation of Liability.</h4>
620
621 <p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
622 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
623 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
624 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
625 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
626 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
627 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
628 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
629 SUCH DAMAGES.</p>
630
631 <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
632
633 <p>If the disclaimer of warranty and limitation of liability provided
634 above cannot be given local legal effect according to their terms,
635 reviewing courts shall apply local law that most closely approximates
636 an absolute waiver of all civil liability in connection with the
637 Program, unless a warranty or assumption of liability accompanies a
638 copy of the Program in return for a fee.</p>
639
640 <p>END OF TERMS AND CONDITIONS</p>
641
642 <h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
643
644 <p>If you develop a new program, and you want it to be of the greatest
645 possible use to the public, the best way to achieve this is to make it
646 free software which everyone can redistribute and change under these terms.</p>
647
648 <p>To do so, attach the following notices to the program. It is safest
649 to attach them to the start of each source file to most effectively
650 state the exclusion of warranty; and each file should have at least
651 the &ldquo;copyright&rdquo; line and a pointer to where the full notice is found.</p>
652
653 <pre> &lt;one line to give the program's name and a brief idea of what it does.&gt;
654 Copyright (C) &lt;year&gt; &lt;name of author&gt;
655
656 This program is free software: you can redistribute it and/or modify
657 it under the terms of the GNU General Public License as published by
658 the Free Software Foundation, either version 3 of the License, or
659 (at your option) any later version.
660
661 This program is distributed in the hope that it will be useful,
662 but WITHOUT ANY WARRANTY; without even the implied warranty of
663 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
664 GNU General Public License for more details.
665
666 You should have received a copy of the GNU General Public License
667 along with this program. If not, see &lt;https://www.gnu.org/licenses/&gt;.
668 </pre>
669
670 <p>Also add information on how to contact you by electronic and paper mail.</p>
671
672 <p>If the program does terminal interaction, make it output a short
673 notice like this when it starts in an interactive mode:</p>
674
675 <pre> &lt;program&gt; Copyright (C) &lt;year&gt; &lt;name of author&gt;
676 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
677 This is free software, and you are welcome to redistribute it
678 under certain conditions; type `show c' for details.
679 </pre>
680
681 <p>The hypothetical commands `show w' and `show c' should show the appropriate
682 parts of the General Public License. Of course, your program's commands
683 might be different; for a GUI interface, you would use an &ldquo;about box&rdquo;.</p>
684
685 <p>You should also get your employer (if you work as a programmer) or school,
686 if any, to sign a &ldquo;copyright disclaimer&rdquo; for the program, if necessary.

689
690 <p>The GNU General Public License does not permit incorporating your program
691 into proprietary programs. If your program is a subroutine library, you
692 may consider it more useful to permit linking proprietary applications with
693 the library. If this is what you want to do, use the GNU Lesser General
694 Public License instead of this License. But first, please read
