     21                        Version 3, 29 June 2007
     22 
     23  Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
     24  Everyone is permitted to copy and distribute verbatim copies
     25  of this license document, but changing it is not allowed.
     26 
     27                             Preamble
     28 
     29   The GNU General Public License is a free, copyleft license for
     30 software and other kinds of works.
     31 
     32   The licenses for most software and other practical works are designed
     33 to take away your freedom to share and change the works.  By contrast,
     34 the GNU General Public License is intended to guarantee your freedom to
     35 share and change all versions of a program--to make sure it remains free
     36 software for all its users.  We, the Free Software Foundation, use the
     37 GNU General Public License for most of our software; it applies also to
     38 any other work released this way by its authors.  You can apply it to
     39 your programs, too.
     40 
     41   When we speak of free software, we are referring to freedom, not
     42 price.  Our General Public Licenses are designed to make sure that you
     43 have the freedom to distribute copies of free software (and charge for
     44 them if you wish), that you receive source code or can get it if you
     45 want it, that you can change the software or use pieces of it in new
     46 free programs, and that you know you can do these things.
     47 
     48   To protect your rights, we need to prevent others from denying you
     49 these rights or asking you to surrender the rights.  Therefore, you have
     50 certain responsibilities if you distribute copies of the software, or if
     51 you modify it: responsibilities to respect the freedom of others.
     52 
     53   For example, if you distribute copies of such a program, whether
     54 gratis or for a fee, you must pass on to the recipients the same
     55 freedoms that you received.  You must make sure that they, too, receive
     56 or can get the source code.  And you must show them these terms so they
     57 know their rights.
     58 
     59   Developers that use the GNU GPL protect your rights with two steps:
     60 (1) assert copyright on the software, and (2) offer you this License
     61 giving you legal permission to copy, distribute and/or modify it.
     62 
     63   For the developers' and authors' protection, the GPL clearly explains
     64 that there is no warranty for this free software.  For both users' and
     65 authors' sake, the GPL requires that modified versions be marked as
     66 changed, so that their problems will not be attributed erroneously to
     67 authors of previous versions.
     68 
     69   Some devices are designed to deny users access to install or run
     70 modified versions of the software inside them, although the manufacturer
     71 can do so.  This is fundamentally incompatible with the aim of
     72 protecting users' freedom to change the software.  The systematic
     73 pattern of such abuse occurs in the area of products for individuals to
     74 use, which is precisely where it is most unacceptable.  Therefore, we
     75 have designed this version of the GPL to prohibit the practice for those
     76 products.  If such problems arise substantially in other domains, we
     77 stand ready to extend this provision to those domains in future versions
     78 of the GPL, as needed to protect the freedom of users.
     79 
     80   Finally, every program is threatened constantly by software patents.
     81 States should not allow patents to restrict development and use of
     82 software on general-purpose computers, but in those that do, we wish to
     83 avoid the special danger that patents applied to a free program could
     84 make it effectively proprietary.  To prevent this, the GPL assures that
     85 patents cannot be used to render the program non-free.
     86 
     87   The precise terms and conditions for copying, distribution and
     88 modification follow.
     89 
     90                        TERMS AND CONDITIONS
     91 
     92   0. Definitions.
     93 
     94   "This License" refers to version 3 of the GNU General Public License.
     95 
     96   "Copyright" also means copyright-like laws that apply to other kinds of
     97 works, such as semiconductor masks.
     98 
     99   "The Program" refers to any copyrightable work licensed under this
    100 License.  Each licensee is addressed as "you".  "Licensees" and
    101 "recipients" may be individuals or organizations.
    102 
    103   To "modify" a work means to copy from or adapt all or part of the work
    104 in a fashion requiring copyright permission, other than the making of an
    105 exact copy.  The resulting work is called a "modified version" of the
    106 earlier work or a work "based on" the earlier work.
    107 
    108   A "covered work" means either the unmodified Program or a work based
    109 on the Program.
    110 
    111   To "propagate" a work means to do anything with it that, without
    112 permission, would make you directly or secondarily liable for
    113 infringement under applicable copyright law, except executing it on a
    114 computer or modifying a private copy.  Propagation includes copying,
    115 distribution (with or without modification), making available to the
    116 public, and in some countries other activities as well.
    117 
    118   To "convey" a work means any kind of propagation that enables other
    119 parties to make or receive copies.  Mere interaction with a user through
    120 a computer network, with no transfer of a copy, is not conveying.
    121 
    122   An interactive user interface displays "Appropriate Legal Notices"
    123 to the extent that it includes a convenient and prominently visible
    124 feature that (1) displays an appropriate copyright notice, and (2)
    125 tells the user that there is no warranty for the work (except to the
    126 extent that warranties are provided), that licensees may convey the
    127 work under this License, and how to view a copy of this License.  If
    128 the interface presents a list of user commands or options, such as a
    129 menu, a prominent item in the list meets this criterion.
    130 
    131   1. Source Code.
    132 
    133   The "source code" for a work means the preferred form of the work
    134 for making modifications to it.  "Object code" means any non-source
    135 form of a work.
    136 
    137   A "Standard Interface" means an interface that either is an official
    138 standard defined by a recognized standards body, or, in the case of
    139 interfaces specified for a particular programming language, one that
    140 is widely used among developers working in that language.
    141 
    142   The "System Libraries" of an executable work include anything, other
    143 than the work as a whole, that (a) is included in the normal form of
    144 packaging a Major Component, but which is not part of that Major
    145 Component, and (b) serves only to enable use of the work with that
    146 Major Component, or to implement a Standard Interface for which an
    147 implementation is available to the public in source code form.  A
    148 "Major Component", in this context, means a major essential component
    149 (kernel, window system, and so on) of the specific operating system
    150 (if any) on which the executable work runs, or a compiler used to
    151 produce the work, or an object code interpreter used to run it.
    152 
    153   The "Corresponding Source" for a work in object code form means all
    154 the source code needed to generate, install, and (for an executable
    155 work) run the object code and to modify the work, including scripts to
    156 control those activities.  However, it does not include the work's
    157 System Libraries, or general-purpose tools or generally available free
    158 programs which are used unmodified in performing those activities but
    159 which are not part of the work.  For example, Corresponding Source
    160 includes interface definition files associated with source files for
    161 the work, and the source code for shared libraries and dynamically
    162 linked subprograms that the work is specifically designed to require,
    163 such as by intimate data communication or control flow between those
    164 subprograms and other parts of the work.
    165 
    166   The Corresponding Source need not include anything that users
    167 can regenerate automatically from other parts of the Corresponding
    168 Source.
    169 
    170   The Corresponding Source for a work in source code form is that
    171 same work.
    172 
    173   2. Basic Permissions.
    174 
    175   All rights granted under this License are granted for the term of
    176 copyright on the Program, and are irrevocable provided the stated
    177 conditions are met.  This License explicitly affirms your unlimited
    178 permission to run the unmodified Program.  The output from running a
    179 covered work is covered by this License only if the output, given its
    180 content, constitutes a covered work.  This License acknowledges your
    181 rights of fair use or other equivalent, as provided by copyright law.
    182 
    183   You may make, run and propagate covered works that you do not
    184 convey, without conditions so long as your license otherwise remains
    185 in force.  You may convey covered works to others for the sole purpose
    186 of having them make modifications exclusively for you, or provide you
    187 with facilities for running those works, provided that you comply with
    188 the terms of this License in conveying all material for which you do
    189 not control copyright.  Those thus making or running the covered works
    190 for you must do so exclusively on your behalf, under your direction
    191 and control, on terms that prohibit them from making any copies of
    192 your copyrighted material outside their relationship with you.
    193 
    194   Conveying under any other circumstances is permitted solely under
    195 the conditions stated below.  Sublicensing is not allowed; section 10
    196 makes it unnecessary.
    197 
    198   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
    199 
    200   No covered work shall be deemed part of an effective technological
    201 measure under any applicable law fulfilling obligations under article
    202 11 of the WIPO copyright treaty adopted on 20 December 1996, or
    203 similar laws prohibiting or restricting circumvention of such
    204 measures.
    205 
    206   When you convey a covered work, you waive any legal power to forbid
    207 circumvention of technological measures to the extent such circumvention
    208 is effected by exercising rights under this License with respect to
    209 the covered work, and you disclaim any intention to limit operation or
    210 modification of the work as a means of enforcing, against the work's
    211 users, your or third parties' legal rights to forbid circumvention of
    212 technological measures.
    213 
    214   4. Conveying Verbatim Copies.
    215 
    216   You may convey verbatim copies of the Program's source code as you
    217 receive it, in any medium, provided that you conspicuously and
    218 appropriately publish on each copy an appropriate copyright notice;
    219 keep intact all notices stating that this License and any
    220 non-permissive terms added in accord with section 7 apply to the code;
    221 keep intact all notices of the absence of any warranty; and give all
    222 recipients a copy of this License along with the Program.
    223 
    224   You may charge any price or no price for each copy that you convey,
    225 and you may offer support or warranty protection for a fee.
    226 
    227   5. Conveying Modified Source Versions.
    228 
    229   You may convey a work based on the Program, or the modifications to
    230 produce it from the Program, in the form of source code under the
    231 terms of section 4, provided that you also meet all of these conditions:
    232 
    233     a) The work must carry prominent notices stating that you modified
    234     it, and giving a relevant date.
    235 
    236     b) The work must carry prominent notices stating that it is
    237     released under this License and any conditions added under section
    238     7.  This requirement modifies the requirement in section 4 to
    239     "keep intact all notices".
    240 
    241     c) You must license the entire work, as a whole, under this
    242     License to anyone who comes into possession of a copy.  This
    243     License will therefore apply, along with any applicable section 7
    244     additional terms, to the whole of the work, and all its parts,
    245     regardless of how they are packaged.  This License gives no
    246     permission to license the work in any other way, but it does not
    247     invalidate such permission if you have separately received it.
    248 
    249     d) If the work has interactive user interfaces, each must display
    250     Appropriate Legal Notices; however, if the Program has interactive
    251     interfaces that do not display Appropriate Legal Notices, your
    252     work need not make them do so.
    253 
    254   A compilation of a covered work with other separate and independent
    255 works, which are not by their nature extensions of the covered work,
    256 and which are not combined with it such as to form a larger program,
    257 in or on a volume of a storage or distribution medium, is called an
    258 "aggregate" if the compilation and its resulting copyright are not
    259 used to limit the access or legal rights of the compilation's users
    260 beyond what the individual works permit.  Inclusion of a covered work
    261 in an aggregate does not cause this License to apply to the other
    262 parts of the aggregate.
    263 
    264   6. Conveying Non-Source Forms.
    265 
    266   You may convey a covered work in object code form under the terms
    267 of sections 4 and 5, provided that you also convey the
    268 machine-readable Corresponding Source under the terms of this License,
    269 in one of these ways:
    270 
    271     a) Convey the object code in, or embodied in, a physical product
    272     (including a physical distribution medium), accompanied by the
    273     Corresponding Source fixed on a durable physical medium
    274     customarily used for software interchange.
    275 
    276     b) Convey the object code in, or embodied in, a physical product
    277     (including a physical distribution medium), accompanied by a
    278     written offer, valid for at least three years and valid for as
    279     long as you offer spare parts or customer support for that product
    280     model, to give anyone who possesses the object code either (1) a
    281     copy of the Corresponding Source for all the software in the
    282     product that is covered by this License, on a durable physical
    283     medium customarily used for software interchange, for a price no
    284     more than your reasonable cost of physically performing this
    285     conveying of source, or (2) access to copy the
    286     Corresponding Source from a network server at no charge.
    287 
    288     c) Convey individual copies of the object code with a copy of the
    289     written offer to provide the Corresponding Source.  This
    290     alternative is allowed only occasionally and noncommercially, and
    291     only if you received the object code with such an offer, in accord
    292     with subsection 6b.
    293 
    294     d) Convey the object code by offering access from a designated
    295     place (gratis or for a charge), and offer equivalent access to the
    296     Corresponding Source in the same way through the same place at no
    297     further charge.  You need not require recipients to copy the
    298     Corresponding Source along with the object code.  If the place to
    299     copy the object code is a network server, the Corresponding Source
    300     may be on a different server (operated by you or a third party)
    301     that supports equivalent copying facilities, provided you maintain
    302     clear directions next to the object code saying where to find the
    303     Corresponding Source.  Regardless of what server hosts the
    304     Corresponding Source, you remain obligated to ensure that it is
    305     available for as long as needed to satisfy these requirements.
    306 
    307     e) Convey the object code using peer-to-peer transmission, provided
    308     you inform other peers where the object code and Corresponding
    309     Source of the work are being offered to the general public at no
    310     charge under subsection 6d.
    311 
    312   A separable portion of the object code, whose source code is excluded
    313 from the Corresponding Source as a System Library, need not be
    314 included in conveying the object code work.
    315 
    316   A "User Product" is either (1) a "consumer product", which means any
    317 tangible personal property which is normally used for personal, family,
    318 or household purposes, or (2) anything designed or sold for incorporation
    319 into a dwelling.  In determining whether a product is a consumer product,
    320 doubtful cases shall be resolved in favor of coverage.  For a particular
    321 product received by a particular user, "normally used" refers to a
    322 typical or common use of that class of product, regardless of the status
    323 of the particular user or of the way in which the particular user
    324 actually uses, or expects or is expected to use, the product.  A product
    325 is a consumer product regardless of whether the product has substantial
    326 commercial, industrial or non-consumer uses, unless such uses represent
    327 the only significant mode of use of the product.
    328 
    329   "Installation Information" for a User Product means any methods,
    330 procedures, authorization keys, or other information required to install
    331 and execute modified versions of a covered work in that User Product from
    332 a modified version of its Corresponding Source.  The information must
    333 suffice to ensure that the continued functioning of the modified object
    334 code is in no case prevented or interfered with solely because
    335 modification has been made.
    336 
    337   If you convey an object code work under this section in, or with, or
    338 specifically for use in, a User Product, and the conveying occurs as
    339 part of a transaction in which the right of possession and use of the
    340 User Product is transferred to the recipient in perpetuity or for a
    341 fixed term (regardless of how the transaction is characterized), the
    342 Corresponding Source conveyed under this section must be accompanied
    343 by the Installation Information.  But this requirement does not apply
    344 if neither you nor any third party retains the ability to install
    345 modified object code on the User Product (for example, the work has
    346 been installed in ROM).
    347 
    348   The requirement to provide Installation Information does not include a
    349 requirement to continue to provide support service, warranty, or updates
    350 for a work that has been modified or installed by the recipient, or for
    351 the User Product in which it has been modified or installed.  Access to a
    352 network may be denied when the modification itself materially and
    353 adversely affects the operation of the network or violates the rules and
    354 protocols for communication across the network.
    355 
    356   Corresponding Source conveyed, and Installation Information provided,
    357 in accord with this section must be in a format that is publicly
    358 documented (and with an implementation available to the public in
    359 source code form), and must require no special password or key for
    360 unpacking, reading or copying.
    361 
    362   7. Additional Terms.
    363 
    364   "Additional permissions" are terms that supplement the terms of this
    365 License by making exceptions from one or more of its conditions.
    366 Additional permissions that are applicable to the entire Program shall
    367 be treated as though they were included in this License, to the extent
    368 that they are valid under applicable law.  If additional permissions
    369 apply only to part of the Program, that part may be used separately
    370 under those permissions, but the entire Program remains governed by
    371 this License without regard to the additional permissions.
    372 
    373   When you convey a copy of a covered work, you may at your option
    374 remove any additional permissions from that copy, or from any part of
    375 it.  (Additional permissions may be written to require their own
    376 removal in certain cases when you modify the work.)  You may place
    377 additional permissions on material, added by you to a covered work,
    378 for which you have or can give appropriate copyright permission.
    379 
    380   Notwithstanding any other provision of this License, for material you
    381 add to a covered work, you may (if authorized by the copyright holders of
    382 that material) supplement the terms of this License with terms:
    383 
    384     a) Disclaiming warranty or limiting liability differently from the
    385     terms of sections 15 and 16 of this License; or
    386 
    387     b) Requiring preservation of specified reasonable legal notices or
    388     author attributions in that material or in the Appropriate Legal
    389     Notices displayed by works containing it; or
    390 
    391     c) Prohibiting misrepresentation of the origin of that material, or
    392     requiring that modified versions of such material be marked in
    393     reasonable ways as different from the original version; or
    394 
    395     d) Limiting the use for publicity purposes of names of licensors or
    396     authors of the material; or
    397 
    398     e) Declining to grant rights under trademark law for use of some
    399     trade names, trademarks, or service marks; or
    400 
    401     f) Requiring indemnification of licensors and authors of that
    402     material by anyone who conveys the material (or modified versions of
    403     it) with contractual assumptions of liability to the recipient, for
    404     any liability that these contractual assumptions directly impose on
    405     those licensors and authors.
    406 
    407   All other non-permissive additional terms are considered "further
    408 restrictions" within the meaning of section 10.  If the Program as you
    409 received it, or any part of it, contains a notice stating that it is
    410 governed by this License along with a term that is a further
    411 restriction, you may remove that term.  If a license document contains
    412 a further restriction but permits relicensing or conveying under this
    413 License, you may add to a covered work material governed by the terms
    414 of that license document, provided that the further restriction does
    415 not survive such relicensing or conveying.
    416 
    417   If you add terms to a covered work in accord with this section, you
    418 must place, in the relevant source files, a statement of the
    419 additional terms that apply to those files, or a notice indicating
    420 where to find the applicable terms.
    421 
    422   Additional terms, permissive or non-permissive, may be stated in the
    423 form of a separately written license, or stated as exceptions;
    424 the above requirements apply either way.
    425 
    426   8. Termination.
    427 
    428   You may not propagate or modify a covered work except as expressly
    429 provided under this License.  Any attempt otherwise to propagate or
    430 modify it is void, and will automatically terminate your rights under
    431 this License (including any patent licenses granted under the third
    432 paragraph of section 11).
    433 
    434   However, if you cease all violation of this License, then your
    435 license from a particular copyright holder is reinstated (a)
    436 provisionally, unless and until the copyright holder explicitly and
    437 finally terminates your license, and (b) permanently, if the copyright
    438 holder fails to notify you of the violation by some reasonable means
    439 prior to 60 days after the cessation.
    440 
    441   Moreover, your license from a particular copyright holder is
    442 reinstated permanently if the copyright holder notifies you of the
    443 violation by some reasonable means, this is the first time you have
    444 received notice of violation of this License (for any work) from that
    445 copyright holder, and you cure the violation prior to 30 days after
    446 your receipt of the notice.
    447 
    448   Termination of your rights under this section does not terminate the
    449 licenses of parties who have received copies or rights from you under
    450 this License.  If your rights have been terminated and not permanently
    451 reinstated, you do not qualify to receive new licenses for the same
    452 material under section 10.
    453 
    454   9. Acceptance Not Required for Having Copies.
    455 
    456   You are not required to accept this License in order to receive or
    457 run a copy of the Program.  Ancillary propagation of a covered work
    458 occurring solely as a consequence of using peer-to-peer transmission
    459 to receive a copy likewise does not require acceptance.  However,
    460 nothing other than this License grants you permission to propagate or
    461 modify any covered work.  These actions infringe copyright if you do
    462 not accept this License.  Therefore, by modifying or propagating a
    463 covered work, you indicate your acceptance of this License to do so.
    464 
    465   10. Automatic Licensing of Downstream Recipients.
    466 
    467   Each time you convey a covered work, the recipient automatically
    468 receives a license from the original licensors, to run, modify and
    469 propagate that work, subject to this License.  You are not responsible
    470 for enforcing compliance by third parties with this License.
    471 
    472   An "entity transaction" is a transaction transferring control of an
    473 organization, or substantially all assets of one, or subdividing an
    474 organization, or merging organizations.  If propagation of a covered
    475 work results from an entity transaction, each party to that
    476 transaction who receives a copy of the work also receives whatever
    477 licenses to the work the party's predecessor in interest had or could
    478 give under the previous paragraph, plus a right to possession of the
    479 Corresponding Source of the work from the predecessor in interest, if
    480 the predecessor has it or can get it with reasonable efforts.
    481 
    482   You may not impose any further restrictions on the exercise of the
    483 rights granted or affirmed under this License.  For example, you may
    484 not impose a license fee, royalty, or other charge for exercise of
    485 rights granted under this License, and you may not initiate litigation
    486 (including a cross-claim or counterclaim in a lawsuit) alleging that
    487 any patent claim is infringed by making, using, selling, offering for
    488 sale, or importing the Program or any portion of it.
    489 
    490   11. Patents.
    491 
    492   A "contributor" is a copyright holder who authorizes use under this
    493 License of the Program or a work on which the Program is based.  The
    494 work thus licensed is called the contributor's "contributor version".
    495 
    496   A contributor's "essential patent claims" are all patent claims
    497 owned or controlled by the contributor, whether already acquired or
    498 hereafter acquired, that would be infringed by some manner, permitted
    499 by this License, of making, using, or selling its contributor version,
    500 but do not include claims that would be infringed only as a
    501 consequence of further modification of the contributor version.  For
    502 purposes of this definition, "control" includes the right to grant
    503 patent sublicenses in a manner consistent with the requirements of
    504 this License.
    505 
    506   Each contributor grants you a non-exclusive, worldwide, royalty-free
    507 patent license under the contributor's essential patent claims, to
    508 make, use, sell, offer for sale, import and otherwise run, modify and
    509 propagate the contents of its contributor version.
    510 
    511   In the following three paragraphs, a "patent license" is any express
    512 agreement or commitment, however denominated, not to enforce a patent
    513 (such as an express permission to practice a patent or covenant not to
    514 sue for patent infringement).  To "grant" such a patent license to a
    515 party means to make such an agreement or commitment not to enforce a
    516 patent against the party.
    517 
    518   If you convey a covered work, knowingly relying on a patent license,
    519 and the Corresponding Source of the work is not available for anyone
    520 to copy, free of charge and under the terms of this License, through a
    521 publicly available network server or other readily accessible means,
    522 then you must either (1) cause the Corresponding Source to be so
    523 available, or (2) arrange to deprive yourself of the benefit of the
    524 patent license for this particular work, or (3) arrange, in a manner
    525 consistent with the requirements of this License, to extend the patent
    526 license to downstream recipients.  "Knowingly relying" means you have
    527 actual knowledge that, but for the patent license, your conveying the
    528 covered work in a country, or your recipient's use of the covered work
    529 in a country, would infringe one or more identifiable patents in that
    530 country that you have reason to believe are valid.
    531 
    532   If, pursuant to or in connection with a single transaction or
    533 arrangement, you convey, or propagate by procuring conveyance of, a
    534 covered work, and grant a patent license to some of the parties
    535 receiving the covered work authorizing them to use, propagate, modify
    536 or convey a specific copy of the covered work, then the patent license
    537 you grant is automatically extended to all recipients of the covered
    538 work and works based on it.
    539 
    540   A patent license is "discriminatory" if it does not include within
    541 the scope of its coverage, prohibits the exercise of, or is
    542 conditioned on the non-exercise of one or more of the rights that are
    543 specifically granted under this License.  You may not convey a covered
    544 work if you are a party to an arrangement with a third party that is
    545 in the business of distributing software, under which you make payment
    546 to the third party based on the extent of your activity of conveying
    547 the work, and under which the third party grants, to any of the
    548 parties who would receive the covered work from you, a discriminatory
    549 patent license (a) in connection with copies of the covered work
    550 conveyed by you (or copies made from those copies), or (b) primarily
    551 for and in connection with specific products or compilations that
    552 contain the covered work, unless you entered into that arrangement,
    553 or that patent license was granted, prior to 28 March 2007.
    554 
    555   Nothing in this License shall be construed as excluding or limiting
    556 any implied license or other defenses to infringement that may
    557 otherwise be available to you under applicable patent law.
    558 
    559   12. No Surrender of Others' Freedom.
    560 
    561   If conditions are imposed on you (whether by court order, agreement or
    562 otherwise) that contradict the conditions of this License, they do not
    563 excuse you from the conditions of this License.  If you cannot convey a
    564 covered work so as to satisfy simultaneously your obligations under this
    565 License and any other pertinent obligations, then as a consequence you may
    566 not convey it at all.  For example, if you agree to terms that obligate you
    567 to collect a royalty for further conveying from those to whom you convey
    568 the Program, the only way you could satisfy both those terms and this
    569 License would be to refrain entirely from conveying the Program.
    570 
    571   13. Use with the GNU Affero General Public License.
    572 
    573   Notwithstanding any other provision of this License, you have
    574 permission to link or combine any covered work with a work licensed
    575 under version 3 of the GNU Affero General Public License into a single
    576 combined work, and to convey the resulting work.  The terms of this
    577 License will continue to apply to the part which is the covered work,
    578 but the special requirements of the GNU Affero General Public License,
    579 section 13, concerning interaction through a network will apply to the
    580 combination as such.
    581 
    582   14. Revised Versions of this License.
    583 
    584   The Free Software Foundation may publish revised and/or new versions of
    585 the GNU General Public License from time to time.  Such new versions will
    586 be similar in spirit to the present version, but may differ in detail to
    587 address new problems or concerns.
    588 
    589   Each version is given a distinguishing version number.  If the
    590 Program specifies that a certain numbered version of the GNU General
    591 Public License "or any later version" applies to it, you have the
    592 option of following the terms and conditions either of that numbered
    593 version or of any later version published by the Free Software
    594 Foundation.  If the Program does not specify a version number of the
    595 GNU General Public License, you may choose any version ever published
    596 by the Free Software Foundation.
    597 
    598   If the Program specifies that a proxy can decide which future
    599 versions of the GNU General Public License can be used, that proxy's
    600 public statement of acceptance of a version permanently authorizes you
    601 to choose that version for the Program.
    602 
    603   Later license versions may give you additional or different
    604 permissions.  However, no additional obligations are imposed on any
    605 author or copyright holder as a result of your choosing to follow a
    606 later version.
    607 
    608   15. Disclaimer of Warranty.
    609 
    610   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
    611 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
    612 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
    613 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
    614 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
    615 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
    616 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
    617 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
    618 
    619   16. Limitation of Liability.
    620 
    621   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
    622 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
    623 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
    624 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
    625 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
    626 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
    627 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
    628 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
    629 SUCH DAMAGES.
    630 
    631   17. Interpretation of Sections 15 and 16.
    632 
    633   If the disclaimer of warranty and limitation of liability provided
    634 above cannot be given local legal effect according to their terms,
    635 reviewing courts shall apply local law that most closely approximates
    636 an absolute waiver of all civil liability in connection with the
    637 Program, unless a warranty or assumption of liability accompanies a
    638 copy of the Program in return for a fee.
