1
+GNU AFFERO GENERAL PUBLIC LICENSE
2
+   Version 3, 19 November 2007
3
+
4
+Copyright (C) 2007 Free Software Foundation, Inc. <http://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

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 <http://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

3
+## What is Kibou?
4
+Kibou is a lightweight federated social networking server based on open protocols. It is
5
+written in Rust, utilizes Rocket as it's web framework and Diesel as it's database driver.
6
+
7
+**Notice**: Kibou is *not* considered stable yet. This project's development is still
8
+work-in-progress. Using the development branch is not recommended for production usage.
9
+
10
+## Federation with other software
11
+Federation is known to work with Pleroma and Mastodon, which are also the main
12
+projects we are testing against right now. But other implementations should work as well.
