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