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

          624             How to Apply These Terms to Your New Programs
          625 
          626   If you develop a new program, and you want it to be of the greatest
          627 possible use to the public, the best way to achieve this is to make it
          628 free software which everyone can redistribute and change under these terms.
          629 
          630   To do so, attach the following notices to the program.  It is safest
          631 to attach them to the start of each source file to most effectively
          632 state the exclusion of warranty; and each file should have at least
          633 the "copyright" line and a pointer to where the full notice is found.
          634 
          635     <one line to give the program's name and a brief idea of what it does.>

          637 
          638     This program is free software: you can redistribute it and/or modify
          639     it under the terms of the GNU General Public License as published by
          640     the Free Software Foundation, either version 3 of the License, or
          641     (at your option) any later version.
          642 
          643     This program is distributed in the hope that it will be useful,
          644     but WITHOUT ANY WARRANTY; without even the implied warranty of
          645     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
          646     GNU General Public License for more details.

          648     You should have received a copy of the GNU General Public License
          649     along with this program.  If not, see <http://www.gnu.org/licenses/>.
          650 
          651 Also add information on how to contact you by electronic and paper mail.
          652 
          653   If the program does terminal interaction, make it output a short
          654 notice like this when it starts in an interactive mode:
          655 
          656     <program>  Copyright (C) <year>  <name of author>
          657     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
          658     This is free software, and you are welcome to redistribute it
          659     under certain conditions; type `show c' for details.
          660 
          661 The hypothetical commands `show w' and `show c' should show the appropriate
          662 parts of the General Public License.  Of course, your program's commands
          663 might be different; for a GUI interface, you would use an "about box".
          664 
          665   You should also get your employer (if you work as a programmer) or school,
          666 if any, to sign a "copyright disclaimer" for the program, if necessary.

          669 
          670   The GNU General Public License does not permit incorporating your program
          671 into proprietary programs.  If your program is a subroutine library, you
          672 may consider it more useful to permit linking proprietary applications with
          673 the library.  If this is what you want to do, use the GNU Lesser General
          674 Public License instead of this License.  But first, please read
