   28                        GENERAL PUBLIC LICENSE
   29                        Version 3, 29 June 2007
   30 
   31                             Preamble
   32 
   33   The General Public License is an open source license for software.
   34 
   35   The licenses for most software and other practical works are designed
   36 to take away your freedom to share and change the works.  By contrast,
   37 the General Public License is intended to guarantee your freedom to
   38 share and change all versions of a program--to make sure it remains open
   39 source for all its users.  The Free Software Foundation uses the
   40 General Public License for most of its software; it applies also to
   41 any other work released this way by its authors.  You can apply it to
   42 your programs, too.
   43 
   44   When we speak of free software, we are referring to freedom, not
   45 price.  General Public Licenses are designed to make sure that you
   46 have the freedom to distribute copies of free software (and charge for
   47 them if you wish), that you receive source code or can get it if you
   48 want it, that you can change the software or use pieces of it in new
   49 free programs, and that you know you can do these things.
   50 
   51   To protect your rights, we need to prevent others from denying you
   52 these rights or asking you to surrender the rights.  Therefore, you have
   53 certain responsibilities if you distribute copies of the software, or if
   54 you modify it: responsibilities to respect the freedom of others.
   55 
   56   For example, if you distribute copies of such a program, whether
   57 gratis or for a fee, you must pass on to the recipients the same
   58 freedoms that you received.  You must make sure that they, too, receive
   59 or can get the source code.  And you must show them these terms so they
   60 know their rights.
   61 
   62   Developers that use the GPL protect your rights with two steps:
   63 (1) assert copyright on the software, and (2) offer you this License
   64 giving you legal permission to copy, distribute and/or modify it.
   65 
   66   For the developers' and authors' protection, the GPL clearly explains
   67 that there is no warranty for this open source software.  For both users'
   68 and authors' sake, the GPL requires that modified versions be marked as
   69 changed, so that their problems will not be attributed erroneously to
   70 authors of previous versions.
   71 
   72   Some devices are designed to deny users access to install or run
   73 modified versions of the software inside them, although the manufacturer
   74 can do so.  This is fundamentally incompatible with the aim of
   75 protecting users' freedom to change the software.  The systematic
   76 pattern of such abuse occurs in the area of products for individuals to
   77 use, which is precisely where it is most unacceptable.  Therefore, we
   78 have designed this version of the GPL to prohibit the practice for those
   79 products.  If such problems arise substantially in other domains, we
   80 stand ready to extend this provision to those domains in future versions
   81 of the GPL, as needed to protect the freedom of users.
   82 
   83   Finally, every program is threatened constantly by software patents.
   84 States should not allow patents to restrict development and use of
   85 software on general-purpose computers, but in those that do, we wish to
   86 avoid the special danger that patents applied to an open source program
   87 could make it effectively proprietary.  To prevent this, the GPL assures
   88 that patents cannot be used to render the program closed-source.
   89 
   90   The precise terms and conditions for copying, distribution and
   91 modification follow.
   92 
   93                        TERMS AND CONDITIONS
   94 
   95   0. Definitions.
   96 
   97   "This License" refers to version 3 of the General Public License.
   98 
   99   "Copyright" also means copyright-like laws that apply to other kinds of
  100 works, such as semiconductor masks.
  101 
  102   "The Program" refers to any copyrightable work licensed under this
  103 License.  Each licensee is addressed as "you".  "Licensees" and
  104 "recipients" may be individuals or organizations.
  105 
  106   To "modify" a work means to copy from or adapt all or part of the work
  107 in a fashion requiring copyright permission, other than the making of an
  108 exact copy.  The resulting work is called a "modified version" of the
  109 earlier work or a work "based on" the earlier work.
  110 
  111   A "covered work" means either the unmodified Program or a work based
  112 on the Program.
  113 
  114   To "propagate" a work means to do anything with it that, without
  115 permission, would make you directly or secondarily liable for
  116 infringement under applicable copyright law, except executing it on a
  117 computer or modifying a private copy.  Propagation includes copying,
  118 distribution (with or without modification), making available to the
  119 public, and in some countries other activities as well.
  120 
  121   To "convey" a work means any kind of propagation that enables other
  122 parties to make or receive copies.  Mere interaction with a user through
  123 a computer network, with no transfer of a copy, is not conveying.
  124 
  125   An interactive user interface displays "Appropriate Legal Notices"
  126 to the extent that it includes a convenient and prominently visible
  127 feature that (1) displays an appropriate copyright notice, and (2)
  128 tells the user that there is no warranty for the work (except to the
  129 extent that warranties are provided), that licensees may convey the
  130 work under this License, and how to view a copy of this License.  If
  131 the interface presents a list of user commands or options, such as a
  132 menu, a prominent item in the list meets this criterion.
  133 
  134   1. Source Code.
  135 
  136   The "source code" for a work means the preferred form of the work
  137 for making modifications to it.  "Object code" means any non-source
  138 form of a work.
  139 
  140   A "Standard Interface" means an interface that either is an official
  141 standard defined by a recognized standards body, or, in the case of
  142 interfaces specified for a particular programming language, one that
  143 is widely used among developers working in that language.
  144 
  145   The "System Libraries" of an executable work include anything, other
  146 than the work as a whole, that (a) is included in the normal form of
  147 packaging a Major Component, but which is not part of that Major
  148 Component, and (b) serves only to enable use of the work with that
  149 Major Component, or to implement a Standard Interface for which an
  150 implementation is available to the public in source code form.  A
  151 "Major Component", in this context, means a major essential component
  152 (kernel, window system, and so on) of the specific operating system
  153 (if any) on which the executable work runs, or a compiler used to
  154 produce the work, or an object code interpreter used to run it.
  155 
  156   The "Corresponding Source" for a work in object code form means all
  157 the source code needed to generate, install, and (for an executable
  158 work) run the object code and to modify the work, including scripts to
  159 control those activities.  However, it does not include the work's
  160 System Libraries, or general-purpose tools or generally available open
  161 source programs which are used unmodified in performing those activities
  162 but which are not part of the work.  For example, Corresponding Source
  163 includes interface definition files associated with source files for
  164 the work, and the source code for shared libraries and dynamically
  165 linked subprograms that the work is specifically designed to require,
  166 such as by intimate data communication or control flow between those
  167 subprograms and other parts of the work.
  168 
  169   The Corresponding Source need not include anything that users
  170 can regenerate automatically from other parts of the Corresponding
  171 Source.
  172 
  173   The Corresponding Source for a work in source code form is that
  174 same work.
  175 
  176   2. Basic Permissions.
  177 
  178   All rights granted under this License are granted for the term of
  179 copyright on the Program, and are irrevocable provided the stated
  180 conditions are met.  This License explicitly affirms your unlimited
  181 permission to run the unmodified Program.  The output from running a
  182 covered work is covered by this License only if the output, given its
  183 content, constitutes a covered work.  This License acknowledges your
  184 rights of fair use or other equivalent, as provided by copyright law.
  185 
  186   You may make, run and propagate covered works that you do not
  187 convey, without conditions so long as your license otherwise remains
  188 in force.  You may convey covered works to others for the sole purpose
  189 of having them make modifications exclusively for you, or provide you
  190 with facilities for running those works, provided that you comply with
  191 the terms of this License in conveying all material for which you do
  192 not control copyright.  Those thus making or running the covered works
  193 for you must do so exclusively on your behalf, under your direction
  194 and control, on terms that prohibit them from making any copies of
  195 your copyrighted material outside their relationship with you.
  196 
  197   Conveying under any other circumstances is permitted solely under
  198 the conditions stated below.  Sublicensing is not allowed; section 10
  199 makes it unnecessary.
  200 
  201   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  202 
  203   No covered work shall be deemed part of an effective technological
  204 measure under any applicable law fulfilling obligations under article
  205 11 of the WIPO copyright treaty adopted on 20 December 1996, or
  206 similar laws prohibiting or restricting circumvention of such
  207 measures.
  208 
  209   When you convey a covered work, you waive any legal power to forbid
  210 circumvention of technological measures to the extent such circumvention
  211 is effected by exercising rights under this License with respect to
  212 the covered work, and you disclaim any intention to limit operation or
  213 modification of the work as a means of enforcing, against the work's
  214 users, your or third parties' legal rights to forbid circumvention of
  215 technological measures.
  216 
  217   4. Conveying Verbatim Copies.
  218 
  219   You may convey verbatim copies of the Program's source code as you
  220 receive it, in any medium, provided that you conspicuously and
  221 appropriately publish on each copy an appropriate copyright notice;
  222 keep intact all notices stating that this License and any
  223 non-permissive terms added in accord with section 7 apply to the code;
  224 keep intact all notices of the absence of any warranty; and give all
  225 recipients a copy of this License along with the Program.
  226 
  227   You may charge any price or no price for each copy that you convey,
  228 and you may offer support or warranty protection for a fee.
  229 
  230   5. Conveying Modified Source Versions.
  231 
  232   You may convey a work based on the Program, or the modifications to
  233 produce it from the Program, in the form of source code under the
  234 terms of section 4, provided that you also meet all of these conditions:
  235 
  236     a) The work must carry prominent notices stating that you modified
  237     it, and giving a relevant date.
  238 
  239     b) The work must carry prominent notices stating that it is
  240     released under this License and any conditions added under section
  241     7.  This requirement modifies the requirement in section 4 to
  242     "keep intact all notices".
  243 
  244     c) You must license the entire work, as a whole, under this
  245     License to anyone who comes into possession of a copy.  This
  246     License will therefore apply, along with any applicable section 7
  247     additional terms, to the whole of the work, and all its parts,
  248     regardless of how they are packaged.  This License gives no
  249     permission to license the work in any other way, but it does not
  250     invalidate such permission if you have separately received it.
  251 
  252     d) If the work has interactive user interfaces, each must display
  253     Appropriate Legal Notices; however, if the Program has interactive
  254     interfaces that do not display Appropriate Legal Notices, your
  255     work need not make them do so.
  256 
  257   A compilation of a covered work with other separate and independent
  258 works, which are not by their nature extensions of the covered work,
  259 and which are not combined with it such as to form a larger program,
  260 in or on a volume of a storage or distribution medium, is called an
  261 "aggregate" if the compilation and its resulting copyright are not
  262 used to limit the access or legal rights of the compilation's users
  263 beyond what the individual works permit.  Inclusion of a covered work
  264 in an aggregate does not cause this License to apply to the other
  265 parts of the aggregate.
  266 
  267   6. Conveying Non-Source Forms.
  268 
  269   You may convey a covered work in object code form under the terms
  270 of sections 4 and 5, provided that you also convey the
  271 machine-readable Corresponding Source under the terms of this License,
  272 in one of these ways:
  273 
  274     a) Convey the object code in, or embodied in, a physical product
  275     (including a physical distribution medium), accompanied by the
  276     Corresponding Source fixed on a durable physical medium
  277     customarily used for software interchange.
  278 
  279     b) Convey the object code in, or embodied in, a physical product
  280     (including a physical distribution medium), accompanied by a
  281     written offer, valid for at least three years and valid for as
  282     long as you offer spare parts or customer support for that product
  283     model, to give anyone who possesses the object code either (1) a
  284     copy of the Corresponding Source for all the software in the
  285     product that is covered by this License, on a durable physical
  286     medium customarily used for software interchange, for a price no
  287     more than your reasonable cost of physically performing this
  288     conveying of source, or (2) access to copy the
  289     Corresponding Source from a network server at no charge.
  290 
  291     c) Convey individual copies of the object code with a copy of the
  292     written offer to provide the Corresponding Source.  This
  293     alternative is allowed only occasionally and noncommercially, and
  294     only if you received the object code with such an offer, in accord
  295     with subsection 6b.
  296 
  297     d) Convey the object code by offering access from a designated
  298     place (gratis or for a charge), and offer equivalent access to the
  299     Corresponding Source in the same way through the same place at no
  300     further charge.  You need not require recipients to copy the
  301     Corresponding Source along with the object code.  If the place to
  302     copy the object code is a network server, the Corresponding Source
  303     may be on a different server (operated by you or a third party)
  304     that supports equivalent copying facilities, provided you maintain
  305     clear directions next to the object code saying where to find the
  306     Corresponding Source.  Regardless of what server hosts the
  307     Corresponding Source, you remain obligated to ensure that it is
  308     available for as long as needed to satisfy these requirements.
  309 
  310     e) Convey the object code using peer-to-peer transmission, provided
  311     you inform other peers where the object code and Corresponding
  312     Source of the work are being offered to the general public at no
  313     charge under subsection 6d.
  314 
  315   A separable portion of the object code, whose source code is excluded
  316 from the Corresponding Source as a System Library, need not be
  317 included in conveying the object code work.
  318 
  319   A "User Product" is either (1) a "consumer product", which means any
  320 tangible personal property which is normally used for personal, family,
  321 or household purposes, or (2) anything designed or sold for incorporation
  322 into a dwelling.  In determining whether a product is a consumer product,
  323 doubtful cases shall be resolved in favor of coverage.  For a particular
  324 product received by a particular user, "normally used" refers to a
  325 typical or common use of that class of product, regardless of the status
  326 of the particular user or of the way in which the particular user
  327 actually uses, or expects or is expected to use, the product.  A product
  328 is a consumer product regardless of whether the product has substantial
  329 commercial, industrial or non-consumer uses, unless such uses represent
  330 the only significant mode of use of the product.
  331 
  332   "Installation Information" for a User Product means any methods,
  333 procedures, authorization keys, or other information required to install
  334 and execute modified versions of a covered work in that User Product from
  335 a modified version of its Corresponding Source.  The information must
  336 suffice to ensure that the continued functioning of the modified object
  337 code is in no case prevented or interfered with solely because
  338 modification has been made.
  339 
  340   If you convey an object code work under this section in, or with, or
  341 specifically for use in, a User Product, and the conveying occurs as
  342 part of a transaction in which the right of possession and use of the
  343 User Product is transferred to the recipient in perpetuity or for a
  344 fixed term (regardless of how the transaction is characterized), the
  345 Corresponding Source conveyed under this section must be accompanied
  346 by the Installation Information.  But this requirement does not apply
  347 if neither you nor any third party retains the ability to install
  348 modified object code on the User Product (for example, the work has
  349 been installed in ROM).
  350 
  351   The requirement to provide Installation Information does not include a
  352 requirement to continue to provide support service, warranty, or updates
  353 for a work that has been modified or installed by the recipient, or for
  354 the User Product in which it has been modified or installed.  Access to a
  355 network may be denied when the modification itself materially and
  356 adversely affects the operation of the network or violates the rules and
  357 protocols for communication across the network.
  358 
  359   Corresponding Source conveyed, and Installation Information provided,
  360 in accord with this section must be in a format that is publicly
  361 documented (and with an implementation available to the public in
  362 source code form), and must require no special password or key for
  363 unpacking, reading or copying.
  364 
  365   7. Additional Terms.
  366 
  367   "Additional permissions" are terms that supplement the terms of this
  368 License by making exceptions from one or more of its conditions.
  369 Additional permissions that are applicable to the entire Program shall
  370 be treated as though they were included in this License, to the extent
  371 that they are valid under applicable law.  If additional permissions
  372 apply only to part of the Program, that part may be used separately
  373 under those permissions, but the entire Program remains governed by
  374 this License without regard to the additional permissions.
  375 
  376   When you convey a copy of a covered work, you may at your option
  377 remove any additional permissions from that copy, or from any part of
  378 it.  (Additional permissions may be written to require their own
  379 removal in certain cases when you modify the work.)  You may place
  380 additional permissions on material, added by you to a covered work,
  381 for which you have or can give appropriate copyright permission.
  382 
  383   Notwithstanding any other provision of this License, for material you
  384 add to a covered work, you may (if authorized by the copyright holders of
  385 that material) supplement the terms of this License with terms:
  386 
  387     a) Disclaiming warranty or limiting liability differently from the
  388     terms of sections 15 and 16 of this License; or
  389 
  390     b) Requiring preservation of specified reasonable legal notices or
  391     author attributions in that material or in the Appropriate Legal
  392     Notices displayed by works containing it; or
  393 
  394     c) Prohibiting misrepresentation of the origin of that material, or
  395     requiring that modified versions of such material be marked in
  396     reasonable ways as different from the original version; or
  397 
  398     d) Limiting the use for publicity purposes of names of licensors or
  399     authors of the material; or
  400 
  401     e) Declining to grant rights under trademark law for use of some
  402     trade names, trademarks, or service marks; or
  403 
  404     f) Requiring indemnification of licensors and authors of that
  405     material by anyone who conveys the material (or modified versions of
  406     it) with contractual assumptions of liability to the recipient, for
  407     any liability that these contractual assumptions directly impose on
  408     those licensors and authors.
  409 
  410   All other non-permissive additional terms are considered "further
  411 restrictions" within the meaning of section 10.  If the Program as you
  412 received it, or any part of it, contains a notice stating that it is
  413 governed by this License along with a term that is a further
  414 restriction, you may remove that term.  If a license document contains
  415 a further restriction but permits relicensing or conveying under this
  416 License, you may add to a covered work material governed by the terms
  417 of that license document, provided that the further restriction does
  418 not survive such relicensing or conveying.
  419 
  420   If you add terms to a covered work in accord with this section, you
  421 must place, in the relevant source files, a statement of the
  422 additional terms that apply to those files, or a notice indicating
  423 where to find the applicable terms.
  424 
  425   Additional terms, permissive or non-permissive, may be stated in the
  426 form of a separately written license, or stated as exceptions;
  427 the above requirements apply either way.
  428 
  429   8. Termination.
  430 
  431   You may not propagate or modify a covered work except as expressly
  432 provided under this License.  Any attempt otherwise to propagate or
  433 modify it is void, and will automatically terminate your rights under
  434 this License (including any patent licenses granted under the third
  435 paragraph of section 11).
  436 
  437   However, if you cease all violation of this License, then your
  438 license from a particular copyright holder is reinstated (a)
  439 provisionally, unless and until the copyright holder explicitly and
  440 finally terminates your license, and (b) permanently, if the copyright
  441 holder fails to notify you of the violation by some reasonable means
  442 prior to 60 days after the cessation.
  443 
  444   Moreover, your license from a particular copyright holder is
  445 reinstated permanently if the copyright holder notifies you of the
  446 violation by some reasonable means, this is the first time you have
  447 received notice of violation of this License (for any work) from that
  448 copyright holder, and you cure the violation prior to 30 days after
  449 your receipt of the notice.
  450 
  451   Termination of your rights under this section does not terminate the
  452 licenses of parties who have received copies or rights from you under
  453 this License.  If your rights have been terminated and not permanently
  454 reinstated, you do not qualify to receive new licenses for the same
  455 material under section 10.
  456 
  457   9. Acceptance Not Required for Having Copies.
  458 
  459   You are not required to accept this License in order to receive or
  460 run a copy of the Program.  Ancillary propagation of a covered work
  461 occurring solely as a consequence of using peer-to-peer transmission
  462 to receive a copy likewise does not require acceptance.  However,
  463 nothing other than this License grants you permission to propagate or
  464 modify any covered work.  These actions infringe copyright if you do
  465 not accept this License.  Therefore, by modifying or propagating a
  466 covered work, you indicate your acceptance of this License to do so.
  467 
  468   10. Automatic Licensing of Downstream Recipients.
  469 
  470   Each time you convey a covered work, the recipient automatically
  471 receives a license from the original licensors, to run, modify and
  472 propagate that work, subject to this License.  You are not responsible
  473 for enforcing compliance by third parties with this License.
  474 
  475   An "entity transaction" is a transaction transferring control of an
  476 organization, or substantially all assets of one, or subdividing an
  477 organization, or merging organizations.  If propagation of a covered
  478 work results from an entity transaction, each party to that
  479 transaction who receives a copy of the work also receives whatever
  480 licenses to the work the party's predecessor in interest had or could
  481 give under the previous paragraph, plus a right to possession of the
  482 Corresponding Source of the work from the predecessor in interest, if
  483 the predecessor has it or can get it with reasonable efforts.
  484 
  485   You may not impose any further restrictions on the exercise of the
  486 rights granted or affirmed under this License.  For example, you may
  487 not impose a license fee, royalty, or other charge for exercise of
  488 rights granted under this License, and you may not initiate litigation
  489 (including a cross-claim or counterclaim in a lawsuit) alleging that
  490 any patent claim is infringed by making, using, selling, offering for
  491 sale, or importing the Program or any portion of it.
  492 
  493   11. Patents.
  494 
  495   A "contributor" is a copyright holder who authorizes use under this
  496 License of the Program or a work on which the Program is based.  The
  497 work thus licensed is called the contributor's "contributor version".
  498 
  499   A contributor's "essential patent claims" are all patent claims
  500 owned or controlled by the contributor, whether already acquired or
  501 hereafter acquired, that would be infringed by some manner, permitted
  502 by this License, of making, using, or selling its contributor version,
  503 but do not include claims that would be infringed only as a
  504 consequence of further modification of the contributor version.  For
  505 purposes of this definition, "control" includes the right to grant
  506 patent sublicenses in a manner consistent with the requirements of
  507 this License.
  508 
  509   Each contributor grants you a non-exclusive, worldwide, royalty-free
  510 patent license under the contributor's essential patent claims, to
  511 make, use, sell, offer for sale, import and otherwise run, modify and
  512 propagate the contents of its contributor version.
  513 
  514   In the following three paragraphs, a "patent license" is any express
  515 agreement or commitment, however denominated, not to enforce a patent
  516 (such as an express permission to practice a patent or covenant not to
  517 sue for patent infringement).  To "grant" such a patent license to a
  518 party means to make such an agreement or commitment not to enforce a
  519 patent against the party.
  520 
  521   If you convey a covered work, knowingly relying on a patent license,
  522 and the Corresponding Source of the work is not available for anyone
  523 to copy, free of charge and under the terms of this License, through a
  524 publicly available network server or other readily accessible means,
  525 then you must either (1) cause the Corresponding Source to be so
  526 available, or (2) arrange to deprive yourself of the benefit of the
  527 patent license for this particular work, or (3) arrange, in a manner
  528 consistent with the requirements of this License, to extend the patent
  529 license to downstream recipients.  "Knowingly relying" means you have
  530 actual knowledge that, but for the patent license, your conveying the
  531 covered work in a country, or your recipient's use of the covered work
  532 in a country, would infringe one or more identifiable patents in that
  533 country that you have reason to believe are valid.
  534 
  535   If, pursuant to or in connection with a single transaction or
  536 arrangement, you convey, or propagate by procuring conveyance of, a
  537 covered work, and grant a patent license to some of the parties
  538 receiving the covered work authorizing them to use, propagate, modify
  539 or convey a specific copy of the covered work, then the patent license
  540 you grant is automatically extended to all recipients of the covered
  541 work and works based on it.
  542 
  543   A patent license is "discriminatory" if it does not include within
  544 the scope of its coverage, prohibits the exercise of, or is
  545 conditioned on the non-exercise of one or more of the rights that are
  546 specifically granted under this License.  You may not convey a covered
  547 work if you are a party to an arrangement with a third party that is
  548 in the business of distributing software, under which you make payment
  549 to the third party based on the extent of your activity of conveying
  550 the work, and under which the third party grants, to any of the
  551 parties who would receive the covered work from you, a discriminatory
  552 patent license (a) in connection with copies of the covered work
  553 conveyed by you (or copies made from those copies), or (b) primarily
  554 for and in connection with specific products or compilations that
  555 contain the covered work, unless you entered into that arrangement,
  556 or that patent license was granted, prior to 28 March 2007.
  557 
  558   Nothing in this License shall be construed as excluding or limiting
  559 any implied license or other defenses to infringement that may
  560 otherwise be available to you under applicable patent law.
  561 
  562   12. No Surrender of Others' Freedom.
  563 
  564   If conditions are imposed on you (whether by court order, agreement or
  565 otherwise) that contradict the conditions of this License, they do not
  566 excuse you from the conditions of this License.  If you cannot convey a
  567 covered work so as to satisfy simultaneously your obligations under this
  568 License and any other pertinent obligations, then as a consequence you may
  569 not convey it at all.  For example, if you agree to terms that obligate you
  570 to collect a royalty for further conveying from those to whom you convey
  571 the Program, the only way you could satisfy both those terms and this
  572 License would be to refrain entirely from conveying the Program.
  573 
  574   13. Use with the Affero General Public License.
  575 
  576   Notwithstanding any other provision of this License, you have
  577 permission to link or combine any covered work with a work licensed
  578 under version 3 of the Affero General Public License into a single
  579 combined work, and to convey the resulting work.  The terms of this
  580 License will continue to apply to the part which is the covered work,
  581 but the special requirements of the Affero General Public License,
  582 section 13, concerning interaction through a network will apply to the
  583 combination as such.
  584 
  585   14. Revised Versions of this License.
  586 
  587   The Free Software Foundation may publish revised and/or new versions of
  588 the General Public License from time to time.  Such new versions will
  589 be similar in spirit to the present version, but may differ in detail to
  590 address new problems or concerns.
  591 
  592   Each version is given a distinguishing version number.  If the
  593 Program specifies that a certain numbered version of the General
  594 Public License "or any later version" applies to it, you have the
  595 option of following the terms and conditions either of that numbered
  596 version or of any later version published by the Free Software
  597 Foundation.  If the Program does not specify a version number of the
  598 General Public License, you may choose any version ever published
  599 by the Free Software Foundation.
  600 
  601   If the Program specifies that a proxy can decide which future
  602 versions of the General Public License can be used, that proxy's
  603 public statement of acceptance of a version permanently authorizes you
  604 to choose that version for the Program.
  605 
  606   Later license versions may give you additional or different
  607 permissions.  However, no additional obligations are imposed on any
  608 author or copyright holder as a result of your choosing to follow a
  609 later version.
  610 
  611   15. Disclaimer of Warranty.
  612 
  613   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
  614 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
  615 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
  616 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
  617 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
  618 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
  619 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
  620 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
  621 
  622   16. Limitation of Liability.
  623 
  624   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
  625 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
  626 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
  627 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
  628 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
  629 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
  630 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
  631 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
  632 SUCH DAMAGES.
  633 
  634   17. Interpretation of Sections 15 and 16.
  635 
  636   If the disclaimer of warranty and limitation of liability provided
  637 above cannot be given local legal effect according to their terms,
  638 reviewing courts shall apply local law that most closely approximates
  639 an absolute waiver of all civil liability in connection with the
  640 Program, unless a warranty or assumption of liability accompanies a
  641 copy of the Program in return for a fee.
  642 
  643                      END OF TERMS AND CONDITIONS
