435 | - `top_p`: Used to discard unlikely text in the sampling process. Lower values will make text more predictable but can become repetitious. (Put this value on 1 to disable its effect)
436 | - `top_k`: Alternative sampling method, can be combined with top_p. The number of highest probability vocabulary tokens to keep for top-k-filtering. (Put this value on 0 to disable its effect)
437 | - `typical_p`: Alternative sampling method described in the paper "Typical_p Decoding for Natural Language Generation" (10.48550/ARXIV.2202.00666). The paper suggests 0.2 as a good value for this setting. Set this setting to 1 to disable its effect.
438 | - `repetition_penalty`: Used to penalize words that were already generated or belong to the context (Going over 1.2 breaks 6B models. Set to 1.0 to disable).
439 | - `penalty_alpha`: The alpha coefficient when using contrastive search.

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

618 | ### How to Apply These Terms to Your New Programs
619 |
620 | If you develop a new program, and you want it to be of the greatest
621 | possible use to the public, the best way to achieve this is to make it
622 | free software which everyone can redistribute and change under these
623 | terms.
624 |
625 | To do so, attach the following notices to the program. It is safest to
626 | attach them to the start of each source file to most effectively state
627 | the exclusion of warranty; and each file should have at least the
628 | "copyright" line and a pointer to where the full notice is found.
629 |
630 |
631 | Copyright (C)

633 | This program is free software: you can redistribute it and/or modify
634 | it under the terms of the GNU Affero General Public License as
635 | published by the Free Software Foundation, either version 3 of the
636 | License, or (at your option) any later version.
637 |
638 | This program is distributed in the hope that it will be useful,
639 | but WITHOUT ANY WARRANTY; without even the implied warranty of
640 | MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
641 | GNU Affero General Public License for more details.
642 |
643 | You should have received a copy of the GNU Affero General Public License
644 | along with this program. If not, see .
645 |
646 | Also add information on how to contact you by electronic and paper
647 | mail.
648 |
649 | If your software can interact with users remotely through a computer
650 | network, you should also make sure that it provides a way for users to
651 | get its source. For example, if your program is a web application, its
652 | interface could display a "Source" link that leads users to an archive
653 | of the code. There are many ways you could offer source, and different
654 | solutions will be better for different programs; see section 13 for
655 | the specific requirements.
656 |
657 | You should also get your employer (if you work as a programmer) or
658 | school, if any, to sign a "copyright disclaimer" for the program, if
659 | necessary. For more information on this, and how to apply and follow
660 | the GNU AGPL, see .
