     3                     GNU GENERAL PUBLIC LICENSE
     4                        Version 3, 29 June 2007
     5 
     6  Copyright (C) 2007 Free Software Foundation, Inc. 
     7  Everyone is permitted to copy and distribute verbatim copies
     8  of this license document, but changing it is not allowed.
     9 
    10                             Preamble
    11 
    12   The GNU General Public License is a free, copyleft license for
    13 software and other kinds of works.
    14 
    15   The licenses for most software and other practical works are designed
    16 to take away your freedom to share and change the works.  By contrast,
    17 the GNU General Public License is intended to guarantee your freedom to
    18 share and change all versions of a program--to make sure it remains free
    19 software for all its users.  We, the Free Software Foundation, use the
    20 GNU General Public License for most of our software; it applies also to
    21 any other work released this way by its authors.  You can apply it to
    22 your programs, too.
    23 
    24   When we speak of free software, we are referring to freedom, not
    25 price.  Our General Public Licenses are designed to make sure that you
    26 have the freedom to distribute copies of free software (and charge for
    27 them if you wish), that you receive source code or can get it if you
    28 want it, that you can change the software or use pieces of it in new
    29 free programs, and that you know you can do these things.
    30 
    31   To protect your rights, we need to prevent others from denying you
    32 these rights or asking you to surrender the rights.  Therefore, you have
    33 certain responsibilities if you distribute copies of the software, or if
    34 you modify it: responsibilities to respect the freedom of others.
    35 
    36   For example, if you distribute copies of such a program, whether
    37 gratis or for a fee, you must pass on to the recipients the same
    38 freedoms that you received.  You must make sure that they, too, receive
    39 or can get the source code.  And you must show them these terms so they
    40 know their rights.
    41 
    42   Developers that use the GNU GPL protect your rights with two steps:
    43 (1) assert copyright on the software, and (2) offer you this License
    44 giving you legal permission to copy, distribute and/or modify it.
    45 
    46   For the developers' and authors' protection, the GPL clearly explains
    47 that there is no warranty for this free software.  For both users' and
    48 authors' sake, the GPL requires that modified versions be marked as
    49 changed, so that their problems will not be attributed erroneously to
    50 authors of previous versions.
    51 
    52   Some devices are designed to deny users access to install or run
    53 modified versions of the software inside them, although the manufacturer
    54 can do so.  This is fundamentally incompatible with the aim of
    55 protecting users' freedom to change the software.  The systematic
    56 pattern of such abuse occurs in the area of products for individuals to
    57 use, which is precisely where it is most unacceptable.  Therefore, we
    58 have designed this version of the GPL to prohibit the practice for those
    59 products.  If such problems arise substantially in other domains, we
    60 stand ready to extend this provision to those domains in future versions
    61 of the GPL, as needed to protect the freedom of users.
    62 
    63   Finally, every program is threatened constantly by software patents.
    64 States should not allow patents to restrict development and use of
    65 software on general-purpose computers, but in those that do, we wish to
    66 avoid the special danger that patents applied to a free program could
    67 make it effectively proprietary.  To prevent this, the GPL assures that
    68 patents cannot be used to render the program non-free.
    69 
    70   The precise terms and conditions for copying, distribution and
    71 modification follow.
    72 
    73                        TERMS AND CONDITIONS
    74 
    75   0. Definitions.
    76 
    77   "This License" refers to version 3 of the GNU General Public License.
    78 
    79   "Copyright" also means copyright-like laws that apply to other kinds of
    80 works, such as semiconductor masks.
    81 
    82   "The Program" refers to any copyrightable work licensed under this
    83 License.  Each licensee is addressed as "you".  "Licensees" and
    84 "recipients" may be individuals or organizations.
    85 
    86   To "modify" a work means to copy from or adapt all or part of the work
    87 in a fashion requiring copyright permission, other than the making of an
    88 exact copy.  The resulting work is called a "modified version" of the
    89 earlier work or a work "based on" the earlier work.
    90 
    91   A "covered work" means either the unmodified Program or a work based
    92 on the Program.
    93 
    94   To "propagate" a work means to do anything with it that, without
    95 permission, would make you directly or secondarily liable for
    96 infringement under applicable copyright law, except executing it on a
    97 computer or modifying a private copy.  Propagation includes copying,
    98 distribution (with or without modification), making available to the
    99 public, and in some countries other activities as well.
   100 
   101   To "convey" a work means any kind of propagation that enables other
   102 parties to make or receive copies.  Mere interaction with a user through
   103 a computer network, with no transfer of a copy, is not conveying.
   104 
   105   An interactive user interface displays "Appropriate Legal Notices"
   106 to the extent that it includes a convenient and prominently visible
   107 feature that (1) displays an appropriate copyright notice, and (2)
   108 tells the user that there is no warranty for the work (except to the
   109 extent that warranties are provided), that licensees may convey the
   110 work under this License, and how to view a copy of this License.  If
   111 the interface presents a list of user commands or options, such as a
   112 menu, a prominent item in the list meets this criterion.
   113 
   114   1. Source Code.
   115 
   116   The "source code" for a work means the preferred form of the work
   117 for making modifications to it.  "Object code" means any non-source
   118 form of a work.
   119 
   120   A "Standard Interface" means an interface that either is an official
   121 standard defined by a recognized standards body, or, in the case of
   122 interfaces specified for a particular programming language, one that
   123 is widely used among developers working in that language.
   124 
   125   The "System Libraries" of an executable work include anything, other
   126 than the work as a whole, that (a) is included in the normal form of
   127 packaging a Major Component, but which is not part of that Major
   128 Component, and (b) serves only to enable use of the work with that
   129 Major Component, or to implement a Standard Interface for which an
   130 implementation is available to the public in source code form.  A
   131 "Major Component", in this context, means a major essential component
   132 (kernel, window system, and so on) of the specific operating system
   133 (if any) on which the executable work runs, or a compiler used to
   134 produce the work, or an object code interpreter used to run it.
   135 
   136   The "Corresponding Source" for a work in object code form means all
   137 the source code needed to generate, install, and (for an executable
   138 work) run the object code and to modify the work, including scripts to
   139 control those activities.  However, it does not include the work's
   140 System Libraries, or general-purpose tools or generally available free
   141 programs which are used unmodified in performing those activities but
   142 which are not part of the work.  For example, Corresponding Source
   143 includes interface definition files associated with source files for
   144 the work, and the source code for shared libraries and dynamically
   145 linked subprograms that the work is specifically designed to require,
   146 such as by intimate data communication or control flow between those
   147 subprograms and other parts of the work.
   148 
   149   The Corresponding Source need not include anything that users
   150 can regenerate automatically from other parts of the Corresponding
   151 Source.
   152 
   153   The Corresponding Source for a work in source code form is that
   154 same work.
   155 
   156   2. Basic Permissions.
   157 
   158   All rights granted under this License are granted for the term of
   159 copyright on the Program, and are irrevocable provided the stated
   160 conditions are met.  This License explicitly affirms your unlimited
   161 permission to run the unmodified Program.  The output from running a
   162 covered work is covered by this License only if the output, given its
   163 content, constitutes a covered work.  This License acknowledges your
   164 rights of fair use or other equivalent, as provided by copyright law.
   165 
   166   You may make, run and propagate covered works that you do not
   167 convey, without conditions so long as your license otherwise remains
   168 in force.  You may convey covered works to others for the sole purpose
   169 of having them make modifications exclusively for you, or provide you
   170 with facilities for running those works, provided that you comply with
   171 the terms of this License in conveying all material for which you do
   172 not control copyright.  Those thus making or running the covered works
   173 for you must do so exclusively on your behalf, under your direction
   174 and control, on terms that prohibit them from making any copies of
   175 your copyrighted material outside their relationship with you.
   176 
   177   Conveying under any other circumstances is permitted solely under
   178 the conditions stated below.  Sublicensing is not allowed; section 10
   179 makes it unnecessary.
   180 
   181   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
   182 
   183   No covered work shall be deemed part of an effective technological
   184 measure under any applicable law fulfilling obligations under article
   185 11 of the WIPO copyright treaty adopted on 20 December 1996, or
   186 similar laws prohibiting or restricting circumvention of such
   187 measures.
   188 
   189   When you convey a covered work, you waive any legal power to forbid
   190 circumvention of technological measures to the extent such circumvention
   191 is effected by exercising rights under this License with respect to
   192 the covered work, and you disclaim any intention to limit operation or
   193 modification of the work as a means of enforcing, against the work's
   194 users, your or third parties' legal rights to forbid circumvention of
   195 technological measures.
   196 
   197   4. Conveying Verbatim Copies.
   198 
   199   You may convey verbatim copies of the Program's source code as you
   200 receive it, in any medium, provided that you conspicuously and
   201 appropriately publish on each copy an appropriate copyright notice;
   202 keep intact all notices stating that this License and any
   203 non-permissive terms added in accord with section 7 apply to the code;
   204 keep intact all notices of the absence of any warranty; and give all
   205 recipients a copy of this License along with the Program.
   206 
   207   You may charge any price or no price for each copy that you convey,
   208 and you may offer support or warranty protection for a fee.
   209 
   210   5. Conveying Modified Source Versions.
   211 
   212   You may convey a work based on the Program, or the modifications to
   213 produce it from the Program, in the form of source code under the
   214 terms of section 4, provided that you also meet all of these conditions:
   215 
   216     a) The work must carry prominent notices stating that you modified
   217     it, and giving a relevant date.
   218 
   219     b) The work must carry prominent notices stating that it is
   220     released under this License and any conditions added under section
   221     7.  This requirement modifies the requirement in section 4 to
   222     "keep intact all notices".
   223 
   224     c) You must license the entire work, as a whole, under this
   225     License to anyone who comes into possession of a copy.  This
   226     License will therefore apply, along with any applicable section 7
   227     additional terms, to the whole of the work, and all its parts,
   228     regardless of how they are packaged.  This License gives no
   229     permission to license the work in any other way, but it does not
   230     invalidate such permission if you have separately received it.
   231 
   232     d) If the work has interactive user interfaces, each must display
   233     Appropriate Legal Notices; however, if the Program has interactive
   234     interfaces that do not display Appropriate Legal Notices, your
   235     work need not make them do so.
   236 
   237   A compilation of a covered work with other separate and independent
   238 works, which are not by their nature extensions of the covered work,
   239 and which are not combined with it such as to form a larger program,
   240 in or on a volume of a storage or distribution medium, is called an
   241 "aggregate" if the compilation and its resulting copyright are not
   242 used to limit the access or legal rights of the compilation's users
   243 beyond what the individual works permit.  Inclusion of a covered work
   244 in an aggregate does not cause this License to apply to the other
   245 parts of the aggregate.
   246 
   247   6. Conveying Non-Source Forms.
   248 
   249   You may convey a covered work in object code form under the terms
   250 of sections 4 and 5, provided that you also convey the
   251 machine-readable Corresponding Source under the terms of this License,
   252 in one of these ways:
   253 
   254     a) Convey the object code in, or embodied in, a physical product
   255     (including a physical distribution medium), accompanied by the
   256     Corresponding Source fixed on a durable physical medium
   257     customarily used for software interchange.
   258 
   259     b) Convey the object code in, or embodied in, a physical product
   260     (including a physical distribution medium), accompanied by a
   261     written offer, valid for at least three years and valid for as
   262     long as you offer spare parts or customer support for that product
   263     model, to give anyone who possesses the object code either (1) a
   264     copy of the Corresponding Source for all the software in the
   265     product that is covered by this License, on a durable physical
   266     medium customarily used for software interchange, for a price no
   267     more than your reasonable cost of physically performing this
   268     conveying of source, or (2) access to copy the
   269     Corresponding Source from a network server at no charge.
   270 
   271     c) Convey individual copies of the object code with a copy of the
   272     written offer to provide the Corresponding Source.  This
   273     alternative is allowed only occasionally and noncommercially, and
   274     only if you received the object code with such an offer, in accord
   275     with subsection 6b.
   276 
   277     d) Convey the object code by offering access from a designated
   278     place (gratis or for a charge), and offer equivalent access to the
   279     Corresponding Source in the same way through the same place at no
   280     further charge.  You need not require recipients to copy the
   281     Corresponding Source along with the object code.  If the place to
   282     copy the object code is a network server, the Corresponding Source
   283     may be on a different server (operated by you or a third party)
   284     that supports equivalent copying facilities, provided you maintain
   285     clear directions next to the object code saying where to find the
   286     Corresponding Source.  Regardless of what server hosts the
   287     Corresponding Source, you remain obligated to ensure that it is
   288     available for as long as needed to satisfy these requirements.
   289 
   290     e) Convey the object code using peer-to-peer transmission, provided
   291     you inform other peers where the object code and Corresponding
   292     Source of the work are being offered to the general public at no
   293     charge under subsection 6d.
   294 
   295   A separable portion of the object code, whose source code is excluded
   296 from the Corresponding Source as a System Library, need not be
   297 included in conveying the object code work.
   298 
   299   A "User Product" is either (1) a "consumer product", which means any
   300 tangible personal property which is normally used for personal, family,
   301 or household purposes, or (2) anything designed or sold for incorporation
   302 into a dwelling.  In determining whether a product is a consumer product,
   303 doubtful cases shall be resolved in favor of coverage.  For a particular
   304 product received by a particular user, "normally used" refers to a
   305 typical or common use of that class of product, regardless of the status
   306 of the particular user or of the way in which the particular user
   307 actually uses, or expects or is expected to use, the product.  A product
   308 is a consumer product regardless of whether the product has substantial
   309 commercial, industrial or non-consumer uses, unless such uses represent
   310 the only significant mode of use of the product.
   311 
   312   "Installation Information" for a User Product means any methods,
   313 procedures, authorization keys, or other information required to install
   314 and execute modified versions of a covered work in that User Product from
   315 a modified version of its Corresponding Source.  The information must
   316 suffice to ensure that the continued functioning of the modified object
   317 code is in no case prevented or interfered with solely because
   318 modification has been made.
   319 
   320   If you convey an object code work under this section in, or with, or
   321 specifically for use in, a User Product, and the conveying occurs as
   322 part of a transaction in which the right of possession and use of the
   323 User Product is transferred to the recipient in perpetuity or for a
   324 fixed term (regardless of how the transaction is characterized), the
   325 Corresponding Source conveyed under this section must be accompanied
   326 by the Installation Information.  But this requirement does not apply
   327 if neither you nor any third party retains the ability to install
   328 modified object code on the User Product (for example, the work has
   329 been installed in ROM).
   330 
   331   The requirement to provide Installation Information does not include a
   332 requirement to continue to provide support service, warranty, or updates
   333 for a work that has been modified or installed by the recipient, or for
   334 the User Product in which it has been modified or installed.  Access to a
   335 network may be denied when the modification itself materially and
   336 adversely affects the operation of the network or violates the rules and
   337 protocols for communication across the network.
   338 
   339   Corresponding Source conveyed, and Installation Information provided,
   340 in accord with this section must be in a format that is publicly
   341 documented (and with an implementation available to the public in
   342 source code form), and must require no special password or key for
   343 unpacking, reading or copying.
   344 
   345   7. Additional Terms.
   346 
   347   "Additional permissions" are terms that supplement the terms of this
   348 License by making exceptions from one or more of its conditions.
   349 Additional permissions that are applicable to the entire Program shall
   350 be treated as though they were included in this License, to the extent
   351 that they are valid under applicable law.  If additional permissions
   352 apply only to part of the Program, that part may be used separately
   353 under those permissions, but the entire Program remains governed by
   354 this License without regard to the additional permissions.
   355 
   356   When you convey a copy of a covered work, you may at your option
   357 remove any additional permissions from that copy, or from any part of
   358 it.  (Additional permissions may be written to require their own
   359 removal in certain cases when you modify the work.)  You may place
   360 additional permissions on material, added by you to a covered work,
   361 for which you have or can give appropriate copyright permission.
   362 
   363   Notwithstanding any other provision of this License, for material you
   364 add to a covered work, you may (if authorized by the copyright holders of
   365 that material) supplement the terms of this License with terms:
   366 
   367     a) Disclaiming warranty or limiting liability differently from the
   368     terms of sections 15 and 16 of this License; or
   369 
   370     b) Requiring preservation of specified reasonable legal notices or
   371     author attributions in that material or in the Appropriate Legal
   372     Notices displayed by works containing it; or
   373 
   374     c) Prohibiting misrepresentation of the origin of that material, or
   375     requiring that modified versions of such material be marked in
   376     reasonable ways as different from the original version; or
   377 
   378     d) Limiting the use for publicity purposes of names of licensors or
   379     authors of the material; or
   380 
   381     e) Declining to grant rights under trademark law for use of some
   382     trade names, trademarks, or service marks; or
   383 
   384     f) Requiring indemnification of licensors and authors of that
   385     material by anyone who conveys the material (or modified versions of
   386     it) with contractual assumptions of liability to the recipient, for
   387     any liability that these contractual assumptions directly impose on
   388     those licensors and authors.
   389 
   390   All other non-permissive additional terms are considered "further
   391 restrictions" within the meaning of section 10.  If the Program as you
   392 received it, or any part of it, contains a notice stating that it is
   393 governed by this License along with a term that is a further
   394 restriction, you may remove that term.  If a license document contains
   395 a further restriction but permits relicensing or conveying under this
   396 License, you may add to a covered work material governed by the terms
   397 of that license document, provided that the further restriction does
   398 not survive such relicensing or conveying.
   399 
   400   If you add terms to a covered work in accord with this section, you
   401 must place, in the relevant source files, a statement of the
   402 additional terms that apply to those files, or a notice indicating
   403 where to find the applicable terms.
   404 
   405   Additional terms, permissive or non-permissive, may be stated in the
   406 form of a separately written license, or stated as exceptions;
   407 the above requirements apply either way.
   408 
   409   8. Termination.
   410 
   411   You may not propagate or modify a covered work except as expressly
   412 provided under this License.  Any attempt otherwise to propagate or
   413 modify it is void, and will automatically terminate your rights under
   414 this License (including any patent licenses granted under the third
   415 paragraph of section 11).
   416 
   417   However, if you cease all violation of this License, then your
   418 license from a particular copyright holder is reinstated (a)
   419 provisionally, unless and until the copyright holder explicitly and
   420 finally terminates your license, and (b) permanently, if the copyright
   421 holder fails to notify you of the violation by some reasonable means
   422 prior to 60 days after the cessation.
   423 
   424   Moreover, your license from a particular copyright holder is
   425 reinstated permanently if the copyright holder notifies you of the
   426 violation by some reasonable means, this is the first time you have
   427 received notice of violation of this License (for any work) from that
   428 copyright holder, and you cure the violation prior to 30 days after
   429 your receipt of the notice.
   430 
   431   Termination of your rights under this section does not terminate the
   432 licenses of parties who have received copies or rights from you under
   433 this License.  If your rights have been terminated and not permanently
   434 reinstated, you do not qualify to receive new licenses for the same
   435 material under section 10.
   436 
   437   9. Acceptance Not Required for Having Copies.
   438 
   439   You are not required to accept this License in order to receive or
   440 run a copy of the Program.  Ancillary propagation of a covered work
   441 occurring solely as a consequence of using peer-to-peer transmission
   442 to receive a copy likewise does not require acceptance.  However,
   443 nothing other than this License grants you permission to propagate or
   444 modify any covered work.  These actions infringe copyright if you do
   445 not accept this License.  Therefore, by modifying or propagating a
   446 covered work, you indicate your acceptance of this License to do so.
   447 
   448   10. Automatic Licensing of Downstream Recipients.
   449 
   450   Each time you convey a covered work, the recipient automatically
   451 receives a license from the original licensors, to run, modify and
   452 propagate that work, subject to this License.  You are not responsible
   453 for enforcing compliance by third parties with this License.
   454 
   455   An "entity transaction" is a transaction transferring control of an
   456 organization, or substantially all assets of one, or subdividing an
   457 organization, or merging organizations.  If propagation of a covered
   458 work results from an entity transaction, each party to that
   459 transaction who receives a copy of the work also receives whatever
   460 licenses to the work the party's predecessor in interest had or could
   461 give under the previous paragraph, plus a right to possession of the
   462 Corresponding Source of the work from the predecessor in interest, if
   463 the predecessor has it or can get it with reasonable efforts.
   464 
   465   You may not impose any further restrictions on the exercise of the
   466 rights granted or affirmed under this License.  For example, you may
   467 not impose a license fee, royalty, or other charge for exercise of
   468 rights granted under this License, and you may not initiate litigation
   469 (including a cross-claim or counterclaim in a lawsuit) alleging that
   470 any patent claim is infringed by making, using, selling, offering for
   471 sale, or importing the Program or any portion of it.
   472 
   473   11. Patents.
   474 
   475   A "contributor" is a copyright holder who authorizes use under this
   476 License of the Program or a work on which the Program is based.  The
   477 work thus licensed is called the contributor's "contributor version".
   478 
   479   A contributor's "essential patent claims" are all patent claims
   480 owned or controlled by the contributor, whether already acquired or
   481 hereafter acquired, that would be infringed by some manner, permitted
   482 by this License, of making, using, or selling its contributor version,
   483 but do not include claims that would be infringed only as a
   484 consequence of further modification of the contributor version.  For
   485 purposes of this definition, "control" includes the right to grant
   486 patent sublicenses in a manner consistent with the requirements of
   487 this License.
   488 
   489   Each contributor grants you a non-exclusive, worldwide, royalty-free
   490 patent license under the contributor's essential patent claims, to
   491 make, use, sell, offer for sale, import and otherwise run, modify and
   492 propagate the contents of its contributor version.
   493 
   494   In the following three paragraphs, a "patent license" is any express
   495 agreement or commitment, however denominated, not to enforce a patent
   496 (such as an express permission to practice a patent or covenant not to
   497 sue for patent infringement).  To "grant" such a patent license to a
   498 party means to make such an agreement or commitment not to enforce a
   499 patent against the party.
   500 
   501   If you convey a covered work, knowingly relying on a patent license,
   502 and the Corresponding Source of the work is not available for anyone
   503 to copy, free of charge and under the terms of this License, through a
   504 publicly available network server or other readily accessible means,
   505 then you must either (1) cause the Corresponding Source to be so
   506 available, or (2) arrange to deprive yourself of the benefit of the
   507 patent license for this particular work, or (3) arrange, in a manner
   508 consistent with the requirements of this License, to extend the patent
   509 license to downstream recipients.  "Knowingly relying" means you have
   510 actual knowledge that, but for the patent license, your conveying the
   511 covered work in a country, or your recipient's use of the covered work
   512 in a country, would infringe one or more identifiable patents in that
   513 country that you have reason to believe are valid.
   514 
   515   If, pursuant to or in connection with a single transaction or
   516 arrangement, you convey, or propagate by procuring conveyance of, a
   517 covered work, and grant a patent license to some of the parties
   518 receiving the covered work authorizing them to use, propagate, modify
   519 or convey a specific copy of the covered work, then the patent license
   520 you grant is automatically extended to all recipients of the covered
   521 work and works based on it.
   522 
   523   A patent license is "discriminatory" if it does not include within
   524 the scope of its coverage, prohibits the exercise of, or is
   525 conditioned on the non-exercise of one or more of the rights that are
   526 specifically granted under this License.  You may not convey a covered
   527 work if you are a party to an arrangement with a third party that is
   528 in the business of distributing software, under which you make payment
   529 to the third party based on the extent of your activity of conveying
   530 the work, and under which the third party grants, to any of the
   531 parties who would receive the covered work from you, a discriminatory
   532 patent license (a) in connection with copies of the covered work
   533 conveyed by you (or copies made from those copies), or (b) primarily
   534 for and in connection with specific products or compilations that
   535 contain the covered work, unless you entered into that arrangement,
   536 or that patent license was granted, prior to 28 March 2007.
   537 
   538   Nothing in this License shall be construed as excluding or limiting
   539 any implied license or other defenses to infringement that may
   540 otherwise be available to you under applicable patent law.
   541 
   542   12. No Surrender of Others' Freedom.
   543 
   544   If conditions are imposed on you (whether by court order, agreement or
   545 otherwise) that contradict the conditions of this License, they do not
   546 excuse you from the conditions of this License.  If you cannot convey a
   547 covered work so as to satisfy simultaneously your obligations under this
   548 License and any other pertinent obligations, then as a consequence you may
   549 not convey it at all.  For example, if you agree to terms that obligate you
   550 to collect a royalty for further conveying from those to whom you convey
   551 the Program, the only way you could satisfy both those terms and this
   552 License would be to refrain entirely from conveying the Program.
   553 
   554   13. Use with the GNU Affero General Public License.
   555 
   556   Notwithstanding any other provision of this License, you have
   557 permission to link or combine any covered work with a work licensed
   558 under version 3 of the GNU Affero General Public License into a single
   559 combined work, and to convey the resulting work.  The terms of this
   560 License will continue to apply to the part which is the covered work,
   561 but the special requirements of the GNU Affero General Public License,
   562 section 13, concerning interaction through a network will apply to the
   563 combination as such.
   564 
   565   14. Revised Versions of this License.
   566 
   567   The Free Software Foundation may publish revised and/or new versions of
   568 the GNU General Public License from time to time.  Such new versions will
   569 be similar in spirit to the present version, but may differ in detail to
   570 address new problems or concerns.
   571 
   572   Each version is given a distinguishing version number.  If the
   573 Program specifies that a certain numbered version of the GNU General
   574 Public License "or any later version" applies to it, you have the
   575 option of following the terms and conditions either of that numbered
   576 version or of any later version published by the Free Software
   577 Foundation.  If the Program does not specify a version number of the
   578 GNU General Public License, you may choose any version ever published
   579 by the Free Software Foundation.
   580 
   581   If the Program specifies that a proxy can decide which future
   582 versions of the GNU General Public License can be used, that proxy's
   583 public statement of acceptance of a version permanently authorizes you
   584 to choose that version for the Program.
   585 
   586   Later license versions may give you additional or different
   587 permissions.  However, no additional obligations are imposed on any
   588 author or copyright holder as a result of your choosing to follow a
   589 later version.
   590 
   591   15. Disclaimer of Warranty.
   592 
   593   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
   594 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
   595 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
   596 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
   597 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
   598 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
   599 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
   600 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
   601 
   602   16. Limitation of Liability.
   603 
   604   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
   605 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
   606 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
   607 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
   608 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
   609 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
   610 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
   611 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
   612 SUCH DAMAGES.
   613 
   614   17. Interpretation of Sections 15 and 16.
   615 
   616   If the disclaimer of warranty and limitation of liability provided
   617 above cannot be given local legal effect according to their terms,
   618 reviewing courts shall apply local law that most closely approximates
   619 an absolute waiver of all civil liability in connection with the
   620 Program, unless a warranty or assumption of liability accompanies a
   621 copy of the Program in return for a fee.
   622 
   623                      END OF TERMS AND CONDITIONS
   624 
   625             How to Apply These Terms to Your New Programs
   626 
   627   If you develop a new program, and you want it to be of the greatest
   628 possible use to the public, the best way to achieve this is to make it
   629 free software which everyone can redistribute and change under these terms.
   630 
   631   To do so, attach the following notices to the program.  It is safest
   632 to attach them to the start of each source file to most effectively
   633 state the exclusion of warranty; and each file should have at least
   634 the "copyright" line and a pointer to where the full notice is found.
   635 
   636     
   637     Copyright (C)   
   638 
   639     This program is free software: you can redistribute it and/or modify
   640     it under the terms of the GNU General Public License as published by
   641     the Free Software Foundation, either version 3 of the License, or
   642     (at your option) any later version.
   643 
   644     This program is distributed in the hope that it will be useful,
   645     but WITHOUT ANY WARRANTY; without even the implied warranty of
   646     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
   647     GNU General Public License for more details.
   648 
   649     You should have received a copy of the GNU General Public License
   650     along with this program.  If not, see .
   651 
   652 Also add information on how to contact you by electronic and paper mail.
   653 
   654   If the program does terminal interaction, make it output a short
   655 notice like this when it starts in an interactive mode:
   656 
   657       Copyright (C)   
   658     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
   659     This is free software, and you are welcome to redistribute it
   660     under certain conditions; type `show c' for details.
   661 
   662 The hypothetical commands `show w' and `show c' should show the appropriate
   663 parts of the General Public License.  Of course, your program's commands
   664 might be different; for a GUI interface, you would use an "about box".
   665 
   666   You should also get your employer (if you work as a programmer) or school,
   667 if any, to sign a "copyright disclaimer" for the program, if necessary.
   668 For more information on this, and how to apply and follow the GNU GPL, see
   669 .
   670 
   671   The GNU General Public License does not permit incorporating your program
   672 into proprietary programs.  If your program is a subroutine library, you
   673 may consider it more useful to permit linking proprietary applications with
   674 the library.  If this is what you want to do, use the GNU Lesser General
   675 Public License instead of this License.  But first, please read
   676 .
