8 | Everyone is permitted to copy and distribute verbatim copies of this license |
9 | document, but changing it is not allowed. |
10 | |
11 | |
12 | Preamble |
13 | -------- |
14 | |
15 | The GNU General Public License is a free, copyleft license for software and |
16 | other kinds of works. |
17 | |
18 | The licenses for most software and other practical works are designed to take |
19 | away your freedom to share and change the works. By contrast, the GNU General |
20 | Public License is intended to guarantee your freedom to share and change all |
21 | versions of a program--to make sure it remains free software for all its users. |
22 | We, the Free Software Foundation, use the GNU General Public License for most of |
23 | our software; it applies also to any other work released this way by its |
24 | authors. You can apply it to your programs, too. |
25 | |
26 | When we speak of free software, we are referring to freedom, not price. Our |
27 | General Public Licenses are designed to make sure that you have the freedom to |
28 | distribute copies of free software (and charge for them if you wish), that you |
29 | receive source code or can get it if you want it, that you can change the |
30 | software or use pieces of it in new free programs, and that you know you can do |
31 | these things. |
32 | |
33 | To protect your rights, we need to prevent others from denying you these rights |
34 | or asking you to surrender the rights. Therefore, you have certain |
35 | responsibilities if you distribute copies of the software, or if you modify it: |
36 | responsibilities to respect the freedom of others. |
37 | |
38 | For example, if you distribute copies of such a program, whether gratis or for a |
39 | fee, you must pass on to the recipients the same freedoms that you received. You |
40 | must make sure that they, too, receive or can get the source code. And you must |
41 | show them these terms so they know their rights. |
42 | |
43 | Developers that use the GNU GPL protect your rights with two steps: (1) assert |
44 | copyright on the software, and (2) offer you this License giving you legal |
45 | permission to copy, distribute and/or modify it. |
46 | |
47 | For the developers' and authors' protection, the GPL clearly explains that there |
48 | is no warranty for this free software. For both users' and authors' sake, the |
49 | GPL requires that modified versions be marked as changed, so that their problems |
50 | will not be attributed erroneously to authors of previous versions. |
51 | |
52 | Some devices are designed to deny users access to install or run modified |
53 | versions of the software inside them, although the manufacturer can do so. This |
54 | is fundamentally incompatible with the aim of protecting users' freedom to |
55 | change the software. The systematic pattern of such abuse occurs in the area of |
56 | products for individuals to use, which is precisely where it is most |
57 | unacceptable. Therefore, we have designed this version of the GPL to prohibit |
58 | the practice for those products. If such problems arise substantially in other |
59 | domains, we stand ready to extend this provision to those domains in future |
60 | versions of the GPL, as needed to protect the freedom of users. |
61 | |
62 | Finally, every program is threatened constantly by software patents. States |
63 | should not allow patents to restrict development and use of software on |
64 | general-purpose computers, but in those that do, we wish to avoid the special |
65 | danger that patents applied to a free program could make it effectively |
66 | proprietary. To prevent this, the GPL assures that patents cannot be used to |
67 | render the program non-free. |
68 | |
69 | The precise terms and conditions for copying, distribution and modification |
70 | follow. |
71 | |
72 | |
73 | TERMS AND CONDITIONS |
74 | -------------------- |
75 | |
76 | |
77 | ### 0. Definitions. |
78 | |
79 | "This License refers to version 3 of the GNU General Public License. |
80 | |
81 | "Copyright" also means copyright-like laws that apply to other kinds of works, |
82 | such as semiconductor masks. |
83 | |
84 | "The Program" refers to any copyrightable work licensed under this License. Each |
85 | licensee is addressed as "you". "Licensees" and "recipients" may be individuals |
86 | or organizations. |
87 | |
88 | To "modify" a work means to copy from or adapt all or part of the work in a |
89 | fashion requiring copyright permission, other than the making of an exact copy. |
90 | The resulting work is called a "modified version" of the earlier work or a work |
91 | "based on" the earlier work. |
92 | |
93 | A "covered work" means either the unmodified Program or a work based on the |
94 | Program. |
95 | |
96 | To "propagate" a work means to do anything with it that, without permission, |
97 | would make you directly or secondarily liable for infringement under applicable |
98 | copyright law, except executing it on a computer or modifying a private copy. |
99 | Propagation includes copying, distribution (with or without modification), |
100 | making available to the public, and in some countries other activities as well. |
101 | |
102 | To "convey" a work means any kind of propagation that enables other parties to |
103 | make or receive copies. Mere interaction with a user through a computer network, |
104 | with no transfer of a copy, is not conveying. |
105 | |
106 | An interactive user interface displays "Appropriate Legal Notices" to the extent |
107 | that it includes a convenient and prominently visible feature that (1) displays |
108 | an appropriate copyright notice, and (2) tells the user that there is no |
109 | warranty for the work (except to the extent that warranties are provided), that |
110 | licensees may convey the work under this License, and how to view a copy of this |
111 | License. If the interface presents a list of user commands or options, such as a |
112 | menu, a prominent item in the list meets this criterion. |
113 | |
114 | |
115 | ### 1. Source Code. |
116 | |
117 | The "source code" for a work means the preferred form of the work for making |
118 | modifications to it. "Object code" means any non-source form of a work. |
119 | |
120 | A "Standard Interface" means an interface that either is an official standard |
121 | defined by a recognized standards body, or, in the case of interfaces specified |
122 | for a particular programming language, one that is widely used among developers |
123 | working in that language. |
124 | |
125 | The "System Libraries" of an executable work include anything, other than the |
126 | work as a whole, that (a) is included in the normal form of packaging a Major |
127 | Component, but which is not part of that Major Component, and (b) serves only to |
128 | enable use of the work with that Major Component, or to implement a Standard |
129 | Interface for which an implementation is available to the public in source code |
130 | form. A "Major Component", in this context, means a major essential component |
131 | (kernel, window system, and so on) of the specific operating system (if any) on |
132 | which the executable work runs, or a compiler used to produce the work, or an |
133 | object code interpreter used to run it. |
134 | |
135 | The "Corresponding Source" for a work in object code form means all the source |
136 | code needed to generate, install, and (for an executable work) run the object |
137 | code and to modify the work, including scripts to control those activities. |
138 | However, it does not include the work's System Libraries, or general-purpose |
139 | tools or generally available free programs which are used unmodified in |
140 | performing those activities but which are not part of the work. For example, |
141 | Corresponding Source includes interface definition files associated with source |
142 | files for the work, and the source code for shared libraries and dynamically |
143 | linked subprograms that the work is specifically designed to require, such as by |
144 | intimate data communication or control flow between those subprograms and other |
145 | parts of the work. |
146 | |
147 | The Corresponding Source need not include anything that users can regenerate |
148 | automatically from other parts of the Corresponding Source. |
149 | |
150 | The Corresponding Source for a work in source code form is that same work. |
151 | |
152 | |
153 | ### 2. Basic Permissions. |
154 | |
155 | All rights granted under this License are granted for the term of copyright on |
156 | the Program, and are irrevocable provided the stated conditions are met. This |
157 | License explicitly affirms your unlimited permission to run the unmodified |
158 | Program. The output from running a covered work is covered by this License only |
159 | if the output, given its content, constitutes a covered work. This License |
160 | acknowledges your rights of fair use or other equivalent, as provided by |
161 | copyright law. |
162 | |
163 | You may make, run and propagate covered works that you do not convey, without |
164 | conditions so long as your license otherwise remains in force. You may convey |
165 | covered works to others for the sole purpose of having them make modifications |
166 | exclusively for you, or provide you with facilities for running those works, |
167 | provided that you comply with the terms of this License in conveying all |
168 | material for which you do not control copyright. Those thus making or running |
169 | the covered works for you must do so exclusively on your behalf, under your |
170 | direction and control, on terms that prohibit them from making any copies of |
171 | your copyrighted material outside their relationship with you. |
172 | |
173 | Conveying under any other circumstances is permitted solely under the conditions |
174 | stated below. Sublicensing is not allowed; section 10 makes it unnecessary. |
175 | |
176 | |
177 | ### 3. Protecting Users' Legal Rights From Anti-Circumvention Law. |
178 | |
179 | No covered work shall be deemed part of an effective technological measure under |
180 | any applicable law fulfilling obligations under article 11 of the WIPO copyright |
181 | treaty adopted on 20 December 1996, or similar laws prohibiting or restricting |
182 | circumvention of such measures. |
183 | |
184 | When you convey a covered work, you waive any legal power to forbid |
185 | circumvention of technological measures to the extent such circumvention is |
186 | effected by exercising rights under this License with respect to the covered |
187 | work, and you disclaim any intention to limit operation or modification of the |
188 | work as a means of enforcing, against the work's users, your or third parties' |
189 | legal rights to forbid circumvention of technological measures. |
190 | |
191 | |
192 | ### 4. Conveying Verbatim Copies. |
193 | |
194 | You may convey verbatim copies of the Program's source code as you receive it, |
195 | in any medium, provided that you conspicuously and appropriately publish on each |
196 | copy an appropriate copyright notice; keep intact all notices stating that this |
197 | License and any non-permissive terms added in accord with section 7 apply to the |
198 | code; keep intact all notices of the absence of any warranty; and give all |
199 | recipients a copy of this License along with the Program. |
200 | |
201 | You may charge any price or no price for each copy that you convey, and you may |
202 | offer support or warranty protection for a fee. |
203 | |
204 | |
205 | ### 5. Conveying Modified Source Versions. |
206 | |
207 | You may convey a work based on the Program, or the modifications to produce it |
208 | from the Program, in the form of source code under the terms of section 4, |
209 | provided that you also meet all of these conditions: |
210 | |
211 | * **a)** The work must carry prominent notices stating that you modified it, |
212 | and giving a relevant date. |
213 | |
214 | * **b)** The work must carry prominent notices stating that it is released |
215 | under this License and any conditions added under section 7. This |
216 | requirement modifies the requirement in section 4 to "keep intact all |
217 | notices". |
218 | |
219 | * **c)** You must license the entire work, as a whole, under this License to |
220 | anyone who comes into possession of a copy. This License will therefore |
221 | apply, along with any applicable section 7 additional terms, to the whole of |
222 | the work, and all its parts, regardless of how they are packaged. This |
223 | License gives no permission to license the work in any other way, but it |
224 | does not invalidate such permission if you have separately received it. |
225 | |
226 | * **d)** If the work has interactive user interfaces, each must display |
227 | Appropriate Legal Notices; however, if the Program has interactive |
228 | interfaces that do not display Appropriate Legal Notices, your work need not |
229 | make them do so. |
230 | |
231 | A compilation of a covered work with other separate and independent works, |
232 | which are not by their nature extensions of the covered work, and which are |
233 | not combined with it such as to form a larger program, in or on a volume of |
234 | a storage or distribution medium, is called an "aggregate" if the |
235 | compilation and its resulting copyright are not used to limit the access or |
236 | legal rights of the compilation's users beyond what the individual works |
237 | permit. Inclusion of a covered work in an aggregate does not cause this |
238 | License to apply to the other parts of the aggregate. |
239 | |
240 | |
241 | ### 6. Conveying Non-Source Forms. |
242 | |
243 | You may convey a covered work in object code form under the terms of sections 4 |
244 | and 5, provided that you also convey the machine-readable Corresponding Source |
245 | under the terms of this License, in one of these ways: |
246 | |
247 | * **a)** Convey the object code in, or embodied in, a physical product |
248 | (including a physical distribution medium), accompanied by the Corresponding |
249 | Source fixed on a durable physical medium customarily used for software |
250 | interchange. |
251 | |
252 | * **b)** Convey the object code in, or embodied in, a physical product |
253 | (including a physical distribution medium), accompanied by a written offer, |
254 | valid for at least three years and valid for as long as you offer spare |
255 | parts or customer support for that product model, to give anyone who |
256 | possesses the object code either (1) a copy of the Corresponding Source for |
257 | all the software in the product that is covered by this License, on a |
258 | durable physical medium customarily used for software interchange, for a |
259 | price no more than your reasonable cost of physically performing this |
260 | conveying of source, or (2) access to copy the Corresponding Source from a |
261 | network server at no charge. |
262 | |
263 | * **c)** Convey individual copies of the object code with a copy of the |
264 | written offer to provide the Corresponding Source. This alternative is |
265 | allowed only occasionally and noncommercially, and only if you received the |
266 | object code with such an offer, in accord with subsection 6b. |
267 | |
268 | * **d)** Convey the object code by offering access from a designated place |
269 | (gratis or for a charge), and offer equivalent access to the Corresponding |
270 | Source in the same way through the same place at no further charge. You need |
271 | not require recipients to copy the Corresponding Source along with the |
272 | object code. If the place to copy the object code is a network server, the |
273 | Corresponding Source may be on a different server (operated by you or a |
274 | third party) that supports equivalent copying facilities, provided you |
275 | maintain clear directions next to the object code saying where to find the |
276 | Corresponding Source. Regardless of what server hosts the Corresponding |
277 | Source, you remain obligated to ensure that it is available for as long as |
278 | needed to satisfy these requirements. |
279 | |
280 | * **e)** Convey the object code using peer-to-peer transmission, provided you |
281 | inform other peers where the object code and Corresponding Source of the |
282 | work are being offered to the general public at no charge under subsection |
283 | 6d. |
284 | |
285 | A separable portion of the object code, whose source code is excluded from |
286 | the Corresponding Source as a System Library, need not be included in |
287 | conveying the object code work. |
288 | |
289 | A "User Product" is either (1) a "consumer product", which means any |
290 | tangible personal property which is normally used for personal, family, or |
291 | household purposes, or (2) anything designed or sold for incorporation into |
292 | a dwelling. In determining whether a product is a consumer product, doubtful |
293 | cases shall be resolved in favor of coverage. For a particular product |
294 | received by a particular user, "normally used" refers to a typical or common |
295 | use of that class of product, regardless of the status of the particular |
296 | user or of the way in which the particular user actually uses, or expects or |
297 | is expected to use, the product. A product is a consumer product regardless |
298 | of whether the product has substantial commercial, industrial or non- |
299 | consumer uses, unless such uses represent the only significant mode of use |
300 | of the product. |
301 | |
302 | "Installation Information" for a User Product means any methods, procedures, |
303 | authorization keys, or other information required to install and execute |
304 | modified versions of a covered work in that User Product from a modified |
305 | version of its Corresponding Source. The information must suffice to ensure |
306 | that the continued functioning of the modified object code is in no case |
307 | prevented or interfered with solely because modification has been made. |
308 | |
309 | If you convey an object code work under this section in, or with, or |
310 | specifically for use in, a User Product, and the conveying occurs as part of |
311 | a transaction in which the right of possession and use of the User Product |
312 | is transferred to the recipient in perpetuity or for a fixed term |
313 | (regardless of how the transaction is characterized), the Corresponding |
314 | Source conveyed under this section must be accompanied by the Installation |
315 | Information. But this requirement does not apply if neither you nor any |
316 | third party retains the ability to install modified object code on the User |
317 | Product (for example, the work has been installed in ROM). |
318 | |
319 | The requirement to provide Installation Information does not include a |
320 | requirement to continue to provide support service, warranty, or updates for |
321 | a work that has been modified or installed by the recipient, or for the User |
322 | Product in which it has been modified or installed. Access to a network may |
323 | be denied when the modification itself materially and adversely affects the |
324 | operation of the network or violates the rules and protocols for |
325 | communication across the network. |
326 | |
327 | Corresponding Source conveyed, and Installation Information provided, in |
328 | accord with this section must be in a format that is publicly documented |
329 | (and with an implementation available to the public in source code form), |
330 | and must require no special password or key for unpacking, reading or |
331 | copying. |
332 | |
333 | |
334 | ### 7. Additional Terms. |
335 | |
336 | "Additional permissions" are terms that supplement the terms of this License by |
337 | making exceptions from one or more of its conditions. Additional permissions |
338 | that are applicable to the entire Program shall be treated as though they were |
339 | included in this License, to the extent that they are valid under applicable |
340 | law. If additional permissions apply only to part of the Program, that part may |
341 | be used separately under those permissions, but the entire Program remains |
342 | governed by this License without regard to the additional permissions. |
343 | |
344 | When you convey a copy of a covered work, you may at your option remove any |
345 | additional permissions from that copy, or from any part of it. (Additional |
346 | permissions may be written to require their own removal in certain cases when |
347 | you modify the work.) You may place additional permissions on material, added by |
348 | you to a covered work, for which you have or can give appropriate copyright |
349 | permission. |
350 | |
351 | Notwithstanding any other provision of this License, for material you add to a |
352 | covered work, you may (if authorized by the copyright holders of that material) |
353 | supplement the terms of this License with terms: |
354 | |
355 | * **a)** Disclaiming warranty or limiting liability differently from the terms |
356 | of sections 15 and 16 of this License; or |
357 | |
358 | * **b)** Requiring preservation of specified reasonable legal notices or |
359 | author attributions in that material or in the Appropriate Legal Notices |
360 | displayed by works containing it; or |
361 | |
362 | * **c)** Prohibiting misrepresentation of the origin of that material, or |
363 | requiring that modified versions of such material be marked in reasonable |
364 | ways as different from the original version; or |
365 | |
366 | * **d)** Limiting the use for publicity purposes of names of licensors or |
367 | authors of the material; or |
368 | |
369 | * **e)** Declining to grant rights under trademark law for use of some trade |
370 | names, trademarks, or service marks; or |
371 | |
372 | * **f)** Requiring indemnification of licensors and authors of that material |
373 | by anyone who conveys the material (or modified versions of it) with |
374 | contractual assumptions of liability to the recipient, for any liability |
375 | that these contractual assumptions directly impose on those licensors and |
376 | authors. |
377 | |
378 | All other non-permissive additional terms are considered "further restrictions" |
379 | within the meaning of section 10. If the Program as you received it, or any part |
380 | of it, contains a notice stating that it is governed by this License along with |
381 | a term that is a further restriction, you may remove that term. If a license |
382 | document contains a further restriction but permits relicensing or conveying |
383 | under this License, you may add to a covered work material governed by the terms |
384 | of that license document, provided that the further restriction does not survive |
385 | such relicensing or conveying. |
386 | |
387 | If you add terms to a covered work in accord with this section, you must place, |
388 | in the relevant source files, a statement of the additional terms that apply to |
389 | those files, or a notice indicating where to find the applicable terms. |
390 | |
391 | Additional terms, permissive or non-permissive, may be stated in the form of a |
392 | separately written license, or stated as exceptions; the above requirements |
393 | apply either way. |
394 | |
395 | |
396 | ### 8. Termination. |
397 | |
398 | You may not propagate or modify a covered work except as expressly provided |
399 | under this License. Any attempt otherwise to propagate or modify it is void, and |
400 | will automatically terminate your rights under this License (including any |
401 | patent licenses granted under the third paragraph of section 11). |
402 | |
403 | However, if you cease all violation of this License, then your license from a |
404 | particular copyright holder is reinstated (a) provisionally, unless and until |
405 | the copyright holder explicitly and finally terminates your license, and (b) |
406 | permanently, if the copyright holder fails to notify you of the violation by |
407 | some reasonable means prior to 60 days after the cessation. |
408 | |
409 | Moreover, your license from a particular copyright holder is reinstated |
410 | permanently if the copyright holder notifies you of the violation by some |
411 | reasonable means, this is the first time you have received notice of violation |
412 | of this License (for any work) from that copyright holder, and you cure the |
413 | violation prior to 30 days after your receipt of the notice. |
414 | |
415 | Termination of your rights under this section does not terminate the licenses of |
416 | parties who have received copies or rights from you under this License. If your |
417 | rights have been terminated and not permanently reinstated, you do not qualify |
418 | to receive new licenses for the same material under section 10. |
419 | |
420 | |
421 | ### 9. Acceptance Not Required for Having Copies. |
422 | |
423 | You are not required to accept this License in order to receive or run a copy of |
424 | the Program. Ancillary propagation of a covered work occurring solely as a |
425 | consequence of using peer-to-peer transmission to receive a copy likewise does |
426 | not require acceptance. However, nothing other than this License grants you |
427 | permission to propagate or modify any covered work. These actions infringe |
428 | copyright if you do not accept this License. Therefore, by modifying or |
429 | propagating a covered work, you indicate your acceptance of this License to do |
430 | so. |
431 | |
432 | |
433 | ### 10. Automatic Licensing of Downstream Recipients. |
434 | |
435 | Each time you convey a covered work, the recipient automatically receives a |
436 | license from the original licensors, to run, modify and propagate that work, |
437 | subject to this License. You are not responsible for enforcing compliance by |
438 | third parties with this License. |
439 | |
440 | An "entity transaction" is a transaction transferring control of an |
441 | organization, or substantially all assets of one, or subdividing an |
442 | organization, or merging organizations. If propagation of a covered work results |
443 | from an entity transaction, each party to that transaction who receives a copy |
444 | of the work also receives whatever licenses to the work the party's predecessor |
445 | in interest had or could give under the previous paragraph, plus a right to |
446 | possession of the Corresponding Source of the work from the predecessor in |
447 | interest, if the predecessor has it or can get it with reasonable efforts. |
448 | |
449 | You may not impose any further restrictions on the exercise of the rights |
450 | granted or affirmed under this License. For example, you may not impose a |
451 | license fee, royalty, or other charge for exercise of rights granted under this |
452 | License, and you may not initiate litigation (including a cross-claim or |
453 | counterclaim in a lawsuit) alleging that any patent claim is infringed by |
454 | making, using, selling, offering for sale, or importing the Program or any |
455 | portion of it. |

458 | ### 11. Patents. |
459 | |
460 | A "contributor" is a copyright holder who authorizes use under this License of |
461 | the Program or a work on which the Program is based. The work thus licensed is |
462 | called the contributor's "contributor version". |
463 | |
464 | A contributor's "essential patent claims" are all patent claims owned or |
465 | controlled by the contributor, whether already acquired or hereafter acquired, |
466 | that would be infringed by some manner, permitted by this License, of making, |
467 | using, or selling its contributor version, but do not include claims that would |
468 | be infringed only as a consequence of further modification of the contributor |
469 | version. For purposes of this definition, "control" includes the right to grant |
470 | patent sublicenses in a manner consistent with the requirements of this License. |
471 | |
472 | Each contributor grants you a non-exclusive, worldwide, royalty-free patent |
473 | license under the contributor's essential patent claims, to make, use, sell, |
474 | offer for sale, import and otherwise run, modify and propagate the contents of |
475 | its contributor version. |
476 | |
477 | In the following three paragraphs, a "patent license" is any express agreement |
478 | or commitment, however denominated, not to enforce a patent (such as an express |
479 | permission to practice a patent or covenant not to sue for patent infringement). |
480 | To "grant" such a patent license to a party means to make such an agreement or |
481 | commitment not to enforce a patent against the party. |
482 | |
483 | If you convey a covered work, knowingly relying on a patent license, and the |
484 | Corresponding Source of the work is not available for anyone to copy, free of |
485 | charge and under the terms of this License, through a publicly available network |
486 | server or other readily accessible means, then you must either (1) cause the |
487 | Corresponding Source to be so available, or (2) arrange to deprive yourself of |
488 | the benefit of the patent license for this particular work, or (3) arrange, in a |
489 | manner consistent with the requirements of this License, to extend the patent |
490 | license to downstream recipients. "Knowingly relying" means you have actual |
491 | knowledge that, but for the patent license, your conveying the covered work in a |
492 | country, or your recipient's use of the covered work in a country, would |
493 | infringe one or more identifiable patents in that country that you have reason |
494 | to believe are valid. |
495 | |
496 | If, pursuant to or in connection with a single transaction or arrangement, you |
497 | convey, or propagate by procuring conveyance of, a covered work, and grant a |
498 | patent license to some of the parties receiving the covered work authorizing |
499 | them to use, propagate, modify or convey a specific copy of the covered work, |
500 | then the patent license you grant is automatically extended to all recipients of |
501 | the covered work and works based on it. |
502 | |
503 | A patent license is "discriminatory" if it does not include within the scope of |
504 | its coverage, prohibits the exercise of, or is conditioned on the non- exercise |
505 | of one or more of the rights that are specifically granted under this License. |
506 | You may not convey a covered work if you are a party to an arrangement with a |
507 | third party that is in the business of distributing software, under which you |
508 | make payment to the third party based on the extent of your activity of |
509 | conveying the work, and under which the third party grants, to any of the |
510 | parties who would receive the covered work from you, a discriminatory patent |
511 | license (a) in connection with copies of the covered work conveyed by you (or |
512 | copies made from those copies), or (b) primarily for and in connection with |
513 | specific products or compilations that contain the covered work, unless you |
514 | entered into that arrangement, or that patent license was granted, prior to 28 |
515 | March 2007. |
516 | |
517 | Nothing in this License shall be construed as excluding or limiting any implied |
518 | license or other defenses to infringement that may otherwise be available to you |
519 | under applicable patent law. |
520 | |
521 | |
522 | ### 12. No Surrender of Others' Freedom. |
523 | |
524 | If conditions are imposed on you (whether by court order, agreement or |
525 | otherwise) that contradict the conditions of this License, they do not excuse |
526 | you from the conditions of this License. If you cannot convey a covered work so |
527 | as to satisfy simultaneously your obligations under this License and any other |
528 | pertinent obligations, then as a consequence you may not convey it at all. For |
529 | example, if you agree to terms that obligate you to collect a royalty for |
530 | further conveying from those to whom you convey the Program, the only way you |
531 | could satisfy both those terms and this License would be to refrain entirely |
532 | from conveying the Program. |
533 | |
534 | |
535 | ### 13. Use with the GNU Affero General Public License. |
536 | |
537 | Notwithstanding any other provision of this License, you have permission to link |
538 | or combine any covered work with a work licensed under version 3 of the GNU |
539 | Affero General Public License into a single combined work, and to convey the |
540 | resulting work. The terms of this License will continue to apply to the part |
541 | which is the covered work, but the special requirements of the GNU Affero |
542 | General Public License, section 13, concerning interaction through a network |
543 | will apply to the combination as such. |
544 | |
545 | |
546 | ### 14. Revised Versions of this License. |
547 | |
548 | The Free Software Foundation may publish revised and/or new versions of the GNU |
549 | General Public License from time to time. Such new versions will be similar in |
550 | spirit to the present version, but may differ in detail to address new problems |
551 | or concerns. |
552 | |
553 | Each version is given a distinguishing version number. If the Program specifies |
554 | that a certain numbered version of the GNU General Public License "or any later |
555 | version" applies to it, you have the option of following the terms and |
556 | conditions either of that numbered version or of any later version published by |
557 | the Free Software Foundation. If the Program does not specify a version number |
558 | of the GNU General Public License, you may choose any version ever published by |
559 | the Free Software Foundation. |
560 | |
561 | If the Program specifies that a proxy can decide which future versions of the |
562 | GNU General Public License can be used, that proxy's public statement of |
563 | acceptance of a version permanently authorizes you to choose that version for |
564 | the Program. |
565 | |
566 | Later license versions may give you additional or different permissions. |
567 | However, no additional obligations are imposed on any author or copyright holder |
568 | as a result of your choosing to follow a later version. |
569 | |
570 | |
571 | ### 15. Disclaimer of Warranty. |
572 | |
573 | THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. |
574 | EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER |
575 | PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER |
576 | EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF |
577 | MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE |
578 | QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE |
579 | DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. |
580 | |
581 | |
582 | ### 16. Limitation of Liability. |
583 | |
584 | IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY |
585 | COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS |
586 | PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, |
587 | INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE |
588 | THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED |
589 | INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE |
590 | PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY |
591 | HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. |
592 | |
593 | ### 17. Interpretation of Sections 15 and 16. |
594 | |
595 | If the disclaimer of warranty and limitation of liability provided above cannot |
596 | be given local legal effect according to their terms, reviewing courts shall |
597 | apply local law that most closely approximates an absolute waiver of all civil |
598 | liability in connection with the Program, unless a warranty or assumption of |
599 | liability accompanies a copy of the Program in return for a fee. |
600 | |

604 | How to Apply These Terms to Your New Programs |
605 | --------------------------------------------- |
606 | |
607 | If you develop a new program, and you want it to be of the greatest possible use |
608 | to the public, the best way to achieve this is to make it free software which |
609 | everyone can redistribute and change under these terms. |
610 | |
611 | To do so, attach the following notices to the program. It is safest to attach |
612 | them to the start of each source file to most effectively state the exclusion of |
613 | warranty; and each file should have at least the "copyright" line and a pointer |
614 | to where the full notice is found. |
615 | |
616 | <one line to give the program's name and a brief idea of what it does.> |
617 | Copyright (C) <year> <name of author> |
618 | |
619 | This program is free software: you can redistribute it and/or modify it |
620 | under the terms of the GNU General Public License as published by the Free |
621 | Software Foundation, either version 3 of the License, or (at your option) |
622 | any later version. |
623 | |
624 | This program is distributed in the hope that it will be useful, but WITHOUT |
625 | ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or |
626 | FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for |
627 | more details. |
628 | |
629 | You should have received a copy of the GNU General Public License along with |
630 | this program. If not, see <http://www.gnu.org/licenses/>. |
631 | |
632 | Also add information on how to contact you by electronic and paper mail. |
633 | |
634 | If the program does terminal interaction, make it output a short notice like |
635 | this when it starts in an interactive mode: |
636 | |
637 | <program> Copyright (C) <year> <name of author> |
638 | This program comes with ABSOLUTELY NO WARRANTY; for details type 'show w'. |
639 | This is free software, and you are welcome to redistribute it under certain |
640 | conditions; type 'show c' for details. |
641 | |
642 | The hypothetical commands 'show w' and 'show c' should show the appropriate |
643 | parts of the General Public License. Of course, your program's commands might be |
644 | different; for a GUI interface, you would use an "about box". |
645 | |
646 | You should also get your employer (if you work as a programmer) or school, if |
647 | any, to sign a "copyright disclaimer" for the program, if necessary. For more |
648 | information on this, and how to apply and follow the GNU GPL, see |
649 | <<http://www.gnu.org/licenses/>>. |
650 | |
651 | The GNU General Public License does not permit incorporating your program into |
652 | proprietary programs. If your program is a subroutine library, you may consider |
653 | it more useful to permit linking proprietary applications with the library. If |
654 | this is what you want to do, use the GNU Lesser General Public License instead |
655 | of this License. But first, please read |
656 | <<http://www.gnu.org/philosophy/why-not-lgpl.html>>. |
