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

688
689 <p>The GNU General Public License does not permit incorporating your program
690 into proprietary programs. If your program is a subroutine library, you
691 may consider it more useful to permit linking proprietary applications with
692 the library. If this is what you want to do, use the GNU Lesser General
693 Public License instead of this License. But first, please read
