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

 1 | # Lemmy-Terminal-Viewer
 2 | 
 3 | Terminal User Interface for lemmy for Linux Terminals (should work in MacOs but i can't test)
 4 | 
 5 | ## Install and Usage 
 6 | 
 7 | ### Linux 
 8 | 
 9 | * Download ```ltv-linux.tar.gz``` from [releases](https://github.com/LunaticHacker/lemmy-terminal-viewer/releases)
10 | * Navigate to download location
11 | * Extract it with ```tar -xf ltv-linux.tar.gz ```
12 | * You can now execute the file using ```./ltv```
13 | * To Install globally move the executable to /usr/bin with ```sudo mv ./ltv /usr/bin```
14 | 
15 | ### Mac
16 | Build the project yourself with cargo (no offical support)
17 | 
18 | ### Loggin In
19 | 
20 | You can log in to as many accounts as you want in any number of instances
21 | 
22 | To add an account run
23 | 
24 | ```
25 | ltv login
26 | ```
27 | You will be prompted to provide login details, if you successfully authenticate you will be redirected to your Feed;
28 | 
29 | To log in to an already added account, run
30 | ```
31 | ltv instance.url username_or_email
32 | ```
33 | 
34 | Or you can always browse without logging in by running
35 | ```
36 | ltv instance.url
37 | ```
38 | 
39 | ### Setting up configs (Optional)
40 | Path for storing configs
41 | 
42 | On Linux: ``` /home/alice/.config/ltv/```
43 | 
44 | On Mac: 
45 | ```/Users/Alice/Library/Application Support/dev.ltv.ltv/```
46 | 
47 | copy the [sample config](ltv.sample.toml) rename it to ltv.toml and save to the path given above
48 | and finally make the changes you desire. All configs are explained in the sample config
49 | 
50 | ### Navigation
51 | 
52 | - Navigation is based on Arrow keys (for now)
53 | 
54 | - use ⬆️ and ⬇️ keys to traverse lists of posts and comments
55 | 
56 | - when viewing a post press ⬇️ to see it's comments
57 | 
58 | - press ➡️ to see a comment's replies and ⬅️ to go back
59 | 
60 | ### Browsing communities
61 | 
62 | In the default view press " i "  to enter edit-mode to select community, enter the name of community and press ➡️  to submit. use ⬅️ to exit editing mode.
