     15                        Version 3, 29 June 2007
     16 
     17  Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
     18  Everyone is permitted to copy and distribute verbatim copies
     19  of this license document, but changing it is not allowed.
     20 
     21                             Preamble
     22 
     23   The GNU General Public License is a free, copyleft license for
     24 software and other kinds of works.
     25 
     26   The licenses for most software and other practical works are designed
     27 to take away your freedom to share and change the works.  By contrast,
     28 the GNU General Public License is intended to guarantee your freedom to
     29 share and change all versions of a program--to make sure it remains free
     30 software for all its users.  We, the Free Software Foundation, use the
     31 GNU General Public License for most of our software; it applies also to
     32 any other work released this way by its authors.  You can apply it to
     33 your programs, too.
     34 
     35   When we speak of free software, we are referring to freedom, not
     36 price.  Our General Public Licenses are designed to make sure that you
     37 have the freedom to distribute copies of free software (and charge for
     38 them if you wish), that you receive source code or can get it if you
     39 want it, that you can change the software or use pieces of it in new
     40 free programs, and that you know you can do these things.
     41 
     42   To protect your rights, we need to prevent others from denying you
     43 these rights or asking you to surrender the rights.  Therefore, you have
     44 certain responsibilities if you distribute copies of the software, or if
     45 you modify it: responsibilities to respect the freedom of others.
     46 
     47   For example, if you distribute copies of such a program, whether
     48 gratis or for a fee, you must pass on to the recipients the same
     49 freedoms that you received.  You must make sure that they, too, receive
     50 or can get the source code.  And you must show them these terms so they
     51 know their rights.
     52 
     53   Developers that use the GNU GPL protect your rights with two steps:
     54 (1) assert copyright on the software, and (2) offer you this License
     55 giving you legal permission to copy, distribute and/or modify it.
     56 
     57   For the developers' and authors' protection, the GPL clearly explains
     58 that there is no warranty for this free software.  For both users' and
     59 authors' sake, the GPL requires that modified versions be marked as
     60 changed, so that their problems will not be attributed erroneously to
     61 authors of previous versions.
     62 
     63   Some devices are designed to deny users access to install or run
     64 modified versions of the software inside them, although the manufacturer
     65 can do so.  This is fundamentally incompatible with the aim of
     66 protecting users' freedom to change the software.  The systematic
     67 pattern of such abuse occurs in the area of products for individuals to
     68 use, which is precisely where it is most unacceptable.  Therefore, we
     69 have designed this version of the GPL to prohibit the practice for those
     70 products.  If such problems arise substantially in other domains, we
     71 stand ready to extend this provision to those domains in future versions
     72 of the GPL, as needed to protect the freedom of users.
     73 
     74   Finally, every program is threatened constantly by software patents.
     75 States should not allow patents to restrict development and use of
     76 software on general-purpose computers, but in those that do, we wish to
     77 avoid the special danger that patents applied to a free program could
     78 make it effectively proprietary.  To prevent this, the GPL assures that
     79 patents cannot be used to render the program non-free.
     80 
     81   The precise terms and conditions for copying, distribution and
     82 modification follow.
     83 
     84                        TERMS AND CONDITIONS
     85 
     86   0. Definitions.
     87 
     88   "This License" refers to version 3 of the GNU General Public License.
     89 
     90   "Copyright" also means copyright-like laws that apply to other kinds of
     91 works, such as semiconductor masks.
     92 
     93   "The Program" refers to any copyrightable work licensed under this
     94 License.  Each licensee is addressed as "you".  "Licensees" and
     95 "recipients" may be individuals or organizations.
     96 
     97   To "modify" a work means to copy from or adapt all or part of the work
     98 in a fashion requiring copyright permission, other than the making of an
     99 exact copy.  The resulting work is called a "modified version" of the
    100 earlier work or a work "based on" the earlier work.
    101 
    102   A "covered work" means either the unmodified Program or a work based
    103 on the Program.
    104 
    105   To "propagate" a work means to do anything with it that, without
    106 permission, would make you directly or secondarily liable for
    107 infringement under applicable copyright law, except executing it on a
    108 computer or modifying a private copy.  Propagation includes copying,
    109 distribution (with or without modification), making available to the
    110 public, and in some countries other activities as well.
    111 
    112   To "convey" a work means any kind of propagation that enables other
    113 parties to make or receive copies.  Mere interaction with a user through
    114 a computer network, with no transfer of a copy, is not conveying.
    115 
    116   An interactive user interface displays "Appropriate Legal Notices"
    117 to the extent that it includes a convenient and prominently visible
    118 feature that (1) displays an appropriate copyright notice, and (2)
    119 tells the user that there is no warranty for the work (except to the
    120 extent that warranties are provided), that licensees may convey the
    121 work under this License, and how to view a copy of this License.  If
    122 the interface presents a list of user commands or options, such as a
    123 menu, a prominent item in the list meets this criterion.
    124 
    125   1. Source Code.
    126 
    127   The "source code" for a work means the preferred form of the work
    128 for making modifications to it.  "Object code" means any non-source
    129 form of a work.
    130 
    131   A "Standard Interface" means an interface that either is an official
    132 standard defined by a recognized standards body, or, in the case of
    133 interfaces specified for a particular programming language, one that
    134 is widely used among developers working in that language.
    135 
    136   The "System Libraries" of an executable work include anything, other
    137 than the work as a whole, that (a) is included in the normal form of
    138 packaging a Major Component, but which is not part of that Major
    139 Component, and (b) serves only to enable use of the work with that
    140 Major Component, or to implement a Standard Interface for which an
    141 implementation is available to the public in source code form.  A
    142 "Major Component", in this context, means a major essential component
    143 (kernel, window system, and so on) of the specific operating system
    144 (if any) on which the executable work runs, or a compiler used to
    145 produce the work, or an object code interpreter used to run it.
    146 
    147   The "Corresponding Source" for a work in object code form means all
    148 the source code needed to generate, install, and (for an executable
    149 work) run the object code and to modify the work, including scripts to
    150 control those activities.  However, it does not include the work's
    151 System Libraries, or general-purpose tools or generally available free
    152 programs which are used unmodified in performing those activities but
    153 which are not part of the work.  For example, Corresponding Source
    154 includes interface definition files associated with source files for
    155 the work, and the source code for shared libraries and dynamically
    156 linked subprograms that the work is specifically designed to require,
    157 such as by intimate data communication or control flow between those
    158 subprograms and other parts of the work.
    159 
    160   The Corresponding Source need not include anything that users
    161 can regenerate automatically from other parts of the Corresponding
    162 Source.
    163 
    164   The Corresponding Source for a work in source code form is that
    165 same work.
    166 
    167   2. Basic Permissions.
    168 
    169   All rights granted under this License are granted for the term of
    170 copyright on the Program, and are irrevocable provided the stated
    171 conditions are met.  This License explicitly affirms your unlimited
    172 permission to run the unmodified Program.  The output from running a
    173 covered work is covered by this License only if the output, given its
    174 content, constitutes a covered work.  This License acknowledges your
    175 rights of fair use or other equivalent, as provided by copyright law.
    176 
    177   You may make, run and propagate covered works that you do not
    178 convey, without conditions so long as your license otherwise remains
    179 in force.  You may convey covered works to others for the sole purpose
    180 of having them make modifications exclusively for you, or provide you
    181 with facilities for running those works, provided that you comply with
    182 the terms of this License in conveying all material for which you do
    183 not control copyright.  Those thus making or running the covered works
    184 for you must do so exclusively on your behalf, under your direction
    185 and control, on terms that prohibit them from making any copies of
    186 your copyrighted material outside their relationship with you.
    187 
    188   Conveying under any other circumstances is permitted solely under
    189 the conditions stated below.  Sublicensing is not allowed; section 10
    190 makes it unnecessary.
    191 
    192   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
    193 
    194   No covered work shall be deemed part of an effective technological
    195 measure under any applicable law fulfilling obligations under article
    196 11 of the WIPO copyright treaty adopted on 20 December 1996, or
    197 similar laws prohibiting or restricting circumvention of such
    198 measures.
    199 
    200   When you convey a covered work, you waive any legal power to forbid
    201 circumvention of technological measures to the extent such circumvention
    202 is effected by exercising rights under this License with respect to
    203 the covered work, and you disclaim any intention to limit operation or
    204 modification of the work as a means of enforcing, against the work's
    205 users, your or third parties' legal rights to forbid circumvention of
    206 technological measures.
    207 
    208   4. Conveying Verbatim Copies.
    209 
    210   You may convey verbatim copies of the Program's source code as you
    211 receive it, in any medium, provided that you conspicuously and
    212 appropriately publish on each copy an appropriate copyright notice;
    213 keep intact all notices stating that this License and any
    214 non-permissive terms added in accord with section 7 apply to the code;
    215 keep intact all notices of the absence of any warranty; and give all
    216 recipients a copy of this License along with the Program.
    217 
    218   You may charge any price or no price for each copy that you convey,
    219 and you may offer support or warranty protection for a fee.
    220 
    221   5. Conveying Modified Source Versions.
    222 
    223   You may convey a work based on the Program, or the modifications to
    224 produce it from the Program, in the form of source code under the
    225 terms of section 4, provided that you also meet all of these conditions:
    226 
    227     a) The work must carry prominent notices stating that you modified
    228     it, and giving a relevant date.
    229 
    230     b) The work must carry prominent notices stating that it is
    231     released under this License and any conditions added under section
    232     7.  This requirement modifies the requirement in section 4 to
    233     "keep intact all notices".
    234 
    235     c) You must license the entire work, as a whole, under this
    236     License to anyone who comes into possession of a copy.  This
    237     License will therefore apply, along with any applicable section 7
    238     additional terms, to the whole of the work, and all its parts,
    239     regardless of how they are packaged.  This License gives no
    240     permission to license the work in any other way, but it does not
    241     invalidate such permission if you have separately received it.
    242 
    243     d) If the work has interactive user interfaces, each must display
    244     Appropriate Legal Notices; however, if the Program has interactive
    245     interfaces that do not display Appropriate Legal Notices, your
    246     work need not make them do so.
    247 
    248   A compilation of a covered work with other separate and independent
    249 works, which are not by their nature extensions of the covered work,
    250 and which are not combined with it such as to form a larger program,
    251 in or on a volume of a storage or distribution medium, is called an
    252 "aggregate" if the compilation and its resulting copyright are not
    253 used to limit the access or legal rights of the compilation's users
    254 beyond what the individual works permit.  Inclusion of a covered work
    255 in an aggregate does not cause this License to apply to the other
    256 parts of the aggregate.
    257 
    258   6. Conveying Non-Source Forms.
    259 
    260   You may convey a covered work in object code form under the terms
    261 of sections 4 and 5, provided that you also convey the
    262 machine-readable Corresponding Source under the terms of this License,
    263 in one of these ways:
    264 
    265     a) Convey the object code in, or embodied in, a physical product
    266     (including a physical distribution medium), accompanied by the
    267     Corresponding Source fixed on a durable physical medium
    268     customarily used for software interchange.
    269 
    270     b) Convey the object code in, or embodied in, a physical product
    271     (including a physical distribution medium), accompanied by a
    272     written offer, valid for at least three years and valid for as
    273     long as you offer spare parts or customer support for that product
    274     model, to give anyone who possesses the object code either (1) a
    275     copy of the Corresponding Source for all the software in the
    276     product that is covered by this License, on a durable physical
    277     medium customarily used for software interchange, for a price no
    278     more than your reasonable cost of physically performing this
    279     conveying of source, or (2) access to copy the
    280     Corresponding Source from a network server at no charge.
    281 
    282     c) Convey individual copies of the object code with a copy of the
    283     written offer to provide the Corresponding Source.  This
    284     alternative is allowed only occasionally and noncommercially, and
    285     only if you received the object code with such an offer, in accord
    286     with subsection 6b.
    287 
    288     d) Convey the object code by offering access from a designated
    289     place (gratis or for a charge), and offer equivalent access to the
    290     Corresponding Source in the same way through the same place at no
    291     further charge.  You need not require recipients to copy the
    292     Corresponding Source along with the object code.  If the place to
    293     copy the object code is a network server, the Corresponding Source
    294     may be on a different server (operated by you or a third party)
    295     that supports equivalent copying facilities, provided you maintain
    296     clear directions next to the object code saying where to find the
    297     Corresponding Source.  Regardless of what server hosts the
    298     Corresponding Source, you remain obligated to ensure that it is
    299     available for as long as needed to satisfy these requirements.
    300 
    301     e) Convey the object code using peer-to-peer transmission, provided
    302     you inform other peers where the object code and Corresponding
    303     Source of the work are being offered to the general public at no
    304     charge under subsection 6d.
    305 
    306   A separable portion of the object code, whose source code is excluded
    307 from the Corresponding Source as a System Library, need not be
    308 included in conveying the object code work.
    309 
    310   A "User Product" is either (1) a "consumer product", which means any
    311 tangible personal property which is normally used for personal, family,
    312 or household purposes, or (2) anything designed or sold for incorporation
    313 into a dwelling.  In determining whether a product is a consumer product,
    314 doubtful cases shall be resolved in favor of coverage.  For a particular
    315 product received by a particular user, "normally used" refers to a
    316 typical or common use of that class of product, regardless of the status
    317 of the particular user or of the way in which the particular user
    318 actually uses, or expects or is expected to use, the product.  A product
    319 is a consumer product regardless of whether the product has substantial
    320 commercial, industrial or non-consumer uses, unless such uses represent
    321 the only significant mode of use of the product.
    322 
    323   "Installation Information" for a User Product means any methods,
    324 procedures, authorization keys, or other information required to install
    325 and execute modified versions of a covered work in that User Product from
    326 a modified version of its Corresponding Source.  The information must
    327 suffice to ensure that the continued functioning of the modified object
    328 code is in no case prevented or interfered with solely because
    329 modification has been made.
    330 
    331   If you convey an object code work under this section in, or with, or
    332 specifically for use in, a User Product, and the conveying occurs as
    333 part of a transaction in which the right of possession and use of the
    334 User Product is transferred to the recipient in perpetuity or for a
    335 fixed term (regardless of how the transaction is characterized), the
    336 Corresponding Source conveyed under this section must be accompanied
    337 by the Installation Information.  But this requirement does not apply
    338 if neither you nor any third party retains the ability to install
    339 modified object code on the User Product (for example, the work has
    340 been installed in ROM).
    341 
    342   The requirement to provide Installation Information does not include a
    343 requirement to continue to provide support service, warranty, or updates
    344 for a work that has been modified or installed by the recipient, or for
    345 the User Product in which it has been modified or installed.  Access to a
    346 network may be denied when the modification itself materially and
    347 adversely affects the operation of the network or violates the rules and
    348 protocols for communication across the network.
    349 
    350   Corresponding Source conveyed, and Installation Information provided,
    351 in accord with this section must be in a format that is publicly
    352 documented (and with an implementation available to the public in
    353 source code form), and must require no special password or key for
    354 unpacking, reading or copying.
    355 
    356   7. Additional Terms.
    357 
    358   "Additional permissions" are terms that supplement the terms of this
    359 License by making exceptions from one or more of its conditions.
    360 Additional permissions that are applicable to the entire Program shall
    361 be treated as though they were included in this License, to the extent
    362 that they are valid under applicable law.  If additional permissions
    363 apply only to part of the Program, that part may be used separately
    364 under those permissions, but the entire Program remains governed by
    365 this License without regard to the additional permissions.
    366 
    367   When you convey a copy of a covered work, you may at your option
    368 remove any additional permissions from that copy, or from any part of
    369 it.  (Additional permissions may be written to require their own
    370 removal in certain cases when you modify the work.)  You may place
    371 additional permissions on material, added by you to a covered work,
    372 for which you have or can give appropriate copyright permission.
    373 
    374   Notwithstanding any other provision of this License, for material you
    375 add to a covered work, you may (if authorized by the copyright holders of
    376 that material) supplement the terms of this License with terms:
    377 
    378     a) Disclaiming warranty or limiting liability differently from the
    379     terms of sections 15 and 16 of this License; or
    380 
    381     b) Requiring preservation of specified reasonable legal notices or
    382     author attributions in that material or in the Appropriate Legal
    383     Notices displayed by works containing it; or
    384 
    385     c) Prohibiting misrepresentation of the origin of that material, or
    386     requiring that modified versions of such material be marked in
    387     reasonable ways as different from the original version; or
    388 
    389     d) Limiting the use for publicity purposes of names of licensors or
    390     authors of the material; or
    391 
    392     e) Declining to grant rights under trademark law for use of some
    393     trade names, trademarks, or service marks; or
    394 
    395     f) Requiring indemnification of licensors and authors of that
    396     material by anyone who conveys the material (or modified versions of
    397     it) with contractual assumptions of liability to the recipient, for
    398     any liability that these contractual assumptions directly impose on
    399     those licensors and authors.

    401   All other non-permissive additional terms are considered "further
    402 restrictions" within the meaning of section 10.  If the Program as you
    403 received it, or any part of it, contains a notice stating that it is
    404 governed by this License along with a term that is a further
    405 restriction, you may remove that term.  If a license document contains
    406 a further restriction but permits relicensing or conveying under this
    407 License, you may add to a covered work material governed by the terms
    408 of that license document, provided that the further restriction does
    409 not survive such relicensing or conveying.
    410 
    411   If you add terms to a covered work in accord with this section, you
    412 must place, in the relevant source files, a statement of the
    413 additional terms that apply to those files, or a notice indicating
    414 where to find the applicable terms.
    415 
    416   Additional terms, permissive or non-permissive, may be stated in the
    417 form of a separately written license, or stated as exceptions;
    418 the above requirements apply either way.
    419 
    420   8. Termination.
    421 
    422   You may not propagate or modify a covered work except as expressly
    423 provided under this License.  Any attempt otherwise to propagate or
    424 modify it is void, and will automatically terminate your rights under
    425 this License (including any patent licenses granted under the third
    426 paragraph of section 11).
    427 
    428   However, if you cease all violation of this License, then your
    429 license from a particular copyright holder is reinstated (a)
    430 provisionally, unless and until the copyright holder explicitly and
    431 finally terminates your license, and (b) permanently, if the copyright
    432 holder fails to notify you of the violation by some reasonable means
    433 prior to 60 days after the cessation.
    434 
    435   Moreover, your license from a particular copyright holder is
    436 reinstated permanently if the copyright holder notifies you of the
    437 violation by some reasonable means, this is the first time you have
    438 received notice of violation of this License (for any work) from that
    439 copyright holder, and you cure the violation prior to 30 days after
    440 your receipt of the notice.
    441 
    442   Termination of your rights under this section does not terminate the
    443 licenses of parties who have received copies or rights from you under
    444 this License.  If your rights have been terminated and not permanently
    445 reinstated, you do not qualify to receive new licenses for the same
    446 material under section 10.
    447 
    448   9. Acceptance Not Required for Having Copies.
    449 
    450   You are not required to accept this License in order to receive or
    451 run a copy of the Program.  Ancillary propagation of a covered work
    452 occurring solely as a consequence of using peer-to-peer transmission
    453 to receive a copy likewise does not require acceptance.  However,
    454 nothing other than this License grants you permission to propagate or
    455 modify any covered work.  These actions infringe copyright if you do
    456 not accept this License.  Therefore, by modifying or propagating a
    457 covered work, you indicate your acceptance of this License to do so.
    458 
    459   10. Automatic Licensing of Downstream Recipients.
    460 
    461   Each time you convey a covered work, the recipient automatically
    462 receives a license from the original licensors, to run, modify and
    463 propagate that work, subject to this License.  You are not responsible
    464 for enforcing compliance by third parties with this License.
    465 
    466   An "entity transaction" is a transaction transferring control of an
    467 organization, or substantially all assets of one, or subdividing an
    468 organization, or merging organizations.  If propagation of a covered
    469 work results from an entity transaction, each party to that
    470 transaction who receives a copy of the work also receives whatever
    471 licenses to the work the party's predecessor in interest had or could
    472 give under the previous paragraph, plus a right to possession of the
    473 Corresponding Source of the work from the predecessor in interest, if
    474 the predecessor has it or can get it with reasonable efforts.
    475 
    476   You may not impose any further restrictions on the exercise of the
    477 rights granted or affirmed under this License.  For example, you may
    478 not impose a license fee, royalty, or other charge for exercise of
    479 rights granted under this License, and you may not initiate litigation
    480 (including a cross-claim or counterclaim in a lawsuit) alleging that
    481 any patent claim is infringed by making, using, selling, offering for
    482 sale, or importing the Program or any portion of it.
    483 
    484   11. Patents.
    485 
    486   A "contributor" is a copyright holder who authorizes use under this
    487 License of the Program or a work on which the Program is based.  The
    488 work thus licensed is called the contributor's "contributor version".
    489 
    490   A contributor's "essential patent claims" are all patent claims
    491 owned or controlled by the contributor, whether already acquired or
    492 hereafter acquired, that would be infringed by some manner, permitted
    493 by this License, of making, using, or selling its contributor version,
    494 but do not include claims that would be infringed only as a
    495 consequence of further modification of the contributor version.  For
    496 purposes of this definition, "control" includes the right to grant
    497 patent sublicenses in a manner consistent with the requirements of
    498 this License.
    499 
    500   Each contributor grants you a non-exclusive, worldwide, royalty-free
    501 patent license under the contributor's essential patent claims, to
    502 make, use, sell, offer for sale, import and otherwise run, modify and
    503 propagate the contents of its contributor version.
    504 
    505   In the following three paragraphs, a "patent license" is any express
    506 agreement or commitment, however denominated, not to enforce a patent
    507 (such as an express permission to practice a patent or covenant not to
    508 sue for patent infringement).  To "grant" such a patent license to a
    509 party means to make such an agreement or commitment not to enforce a
    510 patent against the party.
    511 
    512   If you convey a covered work, knowingly relying on a patent license,
    513 and the Corresponding Source of the work is not available for anyone
    514 to copy, free of charge and under the terms of this License, through a
    515 publicly available network server or other readily accessible means,
    516 then you must either (1) cause the Corresponding Source to be so
    517 available, or (2) arrange to deprive yourself of the benefit of the
    518 patent license for this particular work, or (3) arrange, in a manner
    519 consistent with the requirements of this License, to extend the patent
    520 license to downstream recipients.  "Knowingly relying" means you have
    521 actual knowledge that, but for the patent license, your conveying the
    522 covered work in a country, or your recipient's use of the covered work
    523 in a country, would infringe one or more identifiable patents in that
    524 country that you have reason to believe are valid.
    525 
    526   If, pursuant to or in connection with a single transaction or
    527 arrangement, you convey, or propagate by procuring conveyance of, a
    528 covered work, and grant a patent license to some of the parties
    529 receiving the covered work authorizing them to use, propagate, modify
    530 or convey a specific copy of the covered work, then the patent license
    531 you grant is automatically extended to all recipients of the covered
    532 work and works based on it.
    533 
    534   A patent license is "discriminatory" if it does not include within
    535 the scope of its coverage, prohibits the exercise of, or is
    536 conditioned on the non-exercise of one or more of the rights that are
    537 specifically granted under this License.  You may not convey a covered
    538 work if you are a party to an arrangement with a third party that is
    539 in the business of distributing software, under which you make payment
    540 to the third party based on the extent of your activity of conveying
    541 the work, and under which the third party grants, to any of the
    542 parties who would receive the covered work from you, a discriminatory
    543 patent license (a) in connection with copies of the covered work
    544 conveyed by you (or copies made from those copies), or (b) primarily
    545 for and in connection with specific products or compilations that
    546 contain the covered work, unless you entered into that arrangement,
    547 or that patent license was granted, prior to 28 March 2007.
    548 
    549   Nothing in this License shall be construed as excluding or limiting
    550 any implied license or other defenses to infringement that may
    551 otherwise be available to you under applicable patent law.
    552 
    553   12. No Surrender of Others' Freedom.
    554 
    555   If conditions are imposed on you (whether by court order, agreement or
    556 otherwise) that contradict the conditions of this License, they do not
    557 excuse you from the conditions of this License.  If you cannot convey a
    558 covered work so as to satisfy simultaneously your obligations under this
    559 License and any other pertinent obligations, then as a consequence you may
    560 not convey it at all.  For example, if you agree to terms that obligate you
    561 to collect a royalty for further conveying from those to whom you convey
    562 the Program, the only way you could satisfy both those terms and this
    563 License would be to refrain entirely from conveying the Program.
    564 
    565   13. Use with the GNU Affero General Public License.
    566 
    567   Notwithstanding any other provision of this License, you have
    568 permission to link or combine any covered work with a work licensed
    569 under version 3 of the GNU Affero General Public License into a single
    570 combined work, and to convey the resulting work.  The terms of this
    571 License will continue to apply to the part which is the covered work,
    572 but the special requirements of the GNU Affero General Public License,
    573 section 13, concerning interaction through a network will apply to the
    574 combination as such.
    575 
    576   14. Revised Versions of this License.
    577 
    578   The Free Software Foundation may publish revised and/or new versions of
    579 the GNU General Public License from time to time.  Such new versions will
    580 be similar in spirit to the present version, but may differ in detail to
    581 address new problems or concerns.
    582 
    583   Each version is given a distinguishing version number.  If the
    584 Program specifies that a certain numbered version of the GNU General
    585 Public License "or any later version" applies to it, you have the
    586 option of following the terms and conditions either of that numbered
    587 version or of any later version published by the Free Software
    588 Foundation.  If the Program does not specify a version number of the
    589 GNU General Public License, you may choose any version ever published
    590 by the Free Software Foundation.
    591 
    592   If the Program specifies that a proxy can decide which future
    593 versions of the GNU General Public License can be used, that proxy's
    594 public statement of acceptance of a version permanently authorizes you
    595 to choose that version for the Program.
    596 
    597   Later license versions may give you additional or different
    598 permissions.  However, no additional obligations are imposed on any
    599 author or copyright holder as a result of your choosing to follow a
    600 later version.
    601 
    602   15. Disclaimer of Warranty.
    603 
    604   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
    605 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
    606 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
    607 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
    608 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
    609 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
    610 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
    611 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
    612 
    613   16. Limitation of Liability.
    614 
    615   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
    616 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
    617 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
    618 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
    619 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
    620 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
    621 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
    622 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
    623 SUCH DAMAGES.
    624 
    625   17. Interpretation of Sections 15 and 16.
    626 
    627   If the disclaimer of warranty and limitation of liability provided
    628 above cannot be given local legal effect according to their terms,
    629 reviewing courts shall apply local law that most closely approximates
    630 an absolute waiver of all civil liability in connection with the
    631 Program, unless a warranty or assumption of liability accompanies a
    632 copy of the Program in return for a fee.
    633 
    634                      END OF TERMS AND CONDITIONS
    635 
    636             How to Apply These Terms to Your New Programs
    637 
    638   If you develop a new program, and you want it to be of the greatest
    639 possible use to the public, the best way to achieve this is to make it
    640 free software which everyone can redistribute and change under these terms.
    641 
    642   To do so, attach the following notices to the program.  It is safest
    643 to attach them to the start of each source file to most effectively
    644 state the exclusion of warranty; and each file should have at least
    645 the "copyright" line and a pointer to where the full notice is found.
    646 
    647     <one line to give the program's name and a brief idea of what it does.>
    648     Copyright (C) <year>  <name of author>
    649 
    650     This program is free software: you can redistribute it and/or modify
    651     it under the terms of the GNU General Public License as published by
    652     the Free Software Foundation, either version 3 of the License, or
    653     (at your option) any later version.
    654 
    655     This program is distributed in the hope that it will be useful,
    656     but WITHOUT ANY WARRANTY; without even the implied warranty of
    657     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    658     GNU General Public License for more details.
    659 
    660     You should have received a copy of the GNU General Public License
    661     along with this program.  If not, see <https://www.gnu.org/licenses/>.
    662 
    663 Also add information on how to contact you by electronic and paper mail.
    664 
    665   If the program does terminal interaction, make it output a short
    666 notice like this when it starts in an interactive mode:
    667 
    668     <program>  Copyright (C) <year>  <name of author>
    669     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    670     This is free software, and you are welcome to redistribute it
    671     under certain conditions; type `show c' for details.
    672 
    673 The hypothetical commands `show w' and `show c' should show the appropriate
    674 parts of the General Public License.  Of course, your program's commands
    675 might be different; for a GUI interface, you would use an "about box".
    676 
    677   You should also get your employer (if you work as a programmer) or school,
    678 if any, to sign a "copyright disclaimer" for the program, if necessary.
    679 For more information on this, and how to apply and follow the GNU GPL, see
    680 <https://www.gnu.org/licenses/>.
    681 
    682   The GNU General Public License does not permit incorporating your program
    683 into proprietary programs.  If your program is a subroutine library, you
    684 may consider it more useful to permit linking proprietary applications with
    685 the library.  If this is what you want to do, use the GNU Lesser General
    686 Public License instead of this License.  But first, please read
    687 <https://www.gnu.org/licenses/why-not-lgpl.html>.
