    13   The licenses for most software and other practical works are designed

    14 to take away your freedom to share and change the works.  By contrast,

    40   Developers that use the GNU GPL protect your rights with two steps:
    41 
    41 (1) assert copyright on the software, and (2) offer you this License

    42 giving you legal permission to copy, distribute and/or modify it.
    43 
    43 
    44   You may convey a covered work under sections 3 and 4 of this License
    44   For the developers' and authors' protection, the GPL clearly explains
    45 without being bound by section 3 of the GNU GPL.
    45 that there is no warranty for this free software.  For both users' and
    46 
    46 authors' sake, the GPL requires that modified versions be marked as

    48 
    48 authors of previous versions.
    49   If you modify a copy of the Library, and, in your modifications, a
    49 
    50 facility refers to a function or data to be supplied by an Application
    50   Some devices are designed to deny users access to install or run
    51 that uses the facility (other than as an argument passed when the
    51 modified versions of the software inside them, although the manufacturer
    52 facility is invoked), then you may convey a copy of the modified

    53 protecting users' freedom to change the software.  The systematic
    54 
    54 pattern of such abuse occurs in the area of products for individuals to

    55 use, which is precisely where it is most unacceptable.  Therefore, we
    56    ensure that, in the event an Application does not supply the
    56 have designed this version of the GPL to prohibit the practice for those
    57    function or data, the facility still operates, and performs
    57 products.  If such problems arise substantially in other domains, we
    58    whatever part of its purpose remains meaningful, or
    58 stand ready to extend this provision to those domains in future versions
    59 
    59 of the GPL, as needed to protect the freedom of users.

   167 of having them make modifications exclusively for you, or provide you
       
   168 with facilities for running those works, provided that you comply with
       
   169 the terms of this License in conveying all material for which you do
       
   170 not control copyright.  Those thus making or running the covered works
       
   171 for you must do so exclusively on your behalf, under your direction
       
   172 and control, on terms that prohibit them from making any copies of
       
   173 your copyrighted material outside their relationship with you.
       
   174 
       
   175   Conveying under any other circumstances is permitted solely under
       
   176 the conditions stated below.  Sublicensing is not allowed; section 10
       
   177 makes it unnecessary.
       
   178 
       
   179   3. Protecting Users' Legal Rights From Anti-Circumvention Law.
       
   180 
       
   181   No covered work shall be deemed part of an effective technological
       
   182 measure under any applicable law fulfilling obligations under article
       
   183 11 of the WIPO copyright treaty adopted on 20 December 1996, or
       
   184 similar laws prohibiting or restricting circumvention of such
       
   185 measures.
       
   186 
       
   187   When you convey a covered work, you waive any legal power to forbid
       
   188 circumvention of technological measures to the extent such circumvention
       
   189 is effected by exercising rights under this License with respect to
       
   190 the covered work, and you disclaim any intention to limit operation or
       
   191 modification of the work as a means of enforcing, against the work's
       
   192 users, your or third parties' legal rights to forbid circumvention of
       
   193 technological measures.
       
   194 
       
   195   4. Conveying Verbatim Copies.
       
   196 
       
   197   You may convey verbatim copies of the Program's source code as you
       
   198 receive it, in any medium, provided that you conspicuously and
       
   199 appropriately publish on each copy an appropriate copyright notice;
       
   200 keep intact all notices stating that this License and any
       
   201 non-permissive terms added in accord with section 7 apply to the code;
       
   202 keep intact all notices of the absence of any warranty; and give all
       
   203 recipients a copy of this License along with the Program.
       
   204 
       
   205   You may charge any price or no price for each copy that you convey,
       
   206 and you may offer support or warranty protection for a fee.
       
   207 
       
   208   5. Conveying Modified Source Versions.
       
   209 
       
   210   You may convey a work based on the Program, or the modifications to
       
   211 produce it from the Program, in the form of source code under the
       
   212 terms of section 4, provided that you also meet all of these conditions:
       
   213 
       
   214     a) The work must carry prominent notices stating that you modified
       
   215     it, and giving a relevant date.
       
   216 
       
   217     b) The work must carry prominent notices stating that it is
       
   218     released under this License and any conditions added under section
       
   219     7.  This requirement modifies the requirement in section 4 to
       
   220     "keep intact all notices".
       
   221 
       
   222     c) You must license the entire work, as a whole, under this
       
   223     License to anyone who comes into possession of a copy.  This
       
   224     License will therefore apply, along with any applicable section 7
       
   225     additional terms, to the whole of the work, and all its parts,
       
   226     regardless of how they are packaged.  This License gives no
       
   227     permission to license the work in any other way, but it does not
       
   228     invalidate such permission if you have separately received it.
       
   229 
       
   230     d) If the work has interactive user interfaces, each must display
       
   231     Appropriate Legal Notices; however, if the Program has interactive
       
   232     interfaces that do not display Appropriate Legal Notices, your
       
   233     work need not make them do so.
       
   234 
       
   235   A compilation of a covered work with other separate and independent
       
   236 works, which are not by their nature extensions of the covered work,
       
   237 and which are not combined with it such as to form a larger program,
       
   238 in or on a volume of a storage or distribution medium, is called an
       
   239 "aggregate" if the compilation and its resulting copyright are not
       
   240 used to limit the access or legal rights of the compilation's users
       
   241 beyond what the individual works permit.  Inclusion of a covered work
       
   242 in an aggregate does not cause this License to apply to the other
       
   243 parts of the aggregate.
       
   244 
       
   245   6. Conveying Non-Source Forms.
       
   246 
       
   247   You may convey a covered work in object code form under the terms
       
   248 of sections 4 and 5, provided that you also convey the
       
   249 machine-readable Corresponding Source under the terms of this License,
       
   250 in one of these ways:
       
   251 
       
   252     a) Convey the object code in, or embodied in, a physical product
       
   253     (including a physical distribution medium), accompanied by the
       
   254     Corresponding Source fixed on a durable physical medium
       
   255     customarily used for software interchange.
       
   256 
       
   257     b) Convey the object code in, or embodied in, a physical product
       
   258     (including a physical distribution medium), accompanied by a
       
   259     written offer, valid for at least three years and valid for as
       
   260     long as you offer spare parts or customer support for that product
       
   261     model, to give anyone who possesses the object code either (1) a
       
   262     copy of the Corresponding Source for all the software in the
       
   263     product that is covered by this License, on a durable physical
       
   264     medium customarily used for software interchange, for a price no
       
   265     more than your reasonable cost of physically performing this
       
   266     conveying of source, or (2) access to copy the
       
   267     Corresponding Source from a network server at no charge.
       
   268 
       
   269     c) Convey individual copies of the object code with a copy of the
       
   270     written offer to provide the Corresponding Source.  This
       
   271     alternative is allowed only occasionally and noncommercially, and
       
   272     only if you received the object code with such an offer, in accord
       
   273     with subsection 6b.
       
   274 
       
   275     d) Convey the object code by offering access from a designated
       
   276     place (gratis or for a charge), and offer equivalent access to the
       
   277     Corresponding Source in the same way through the same place at no
       
   278     further charge.  You need not require recipients to copy the
       
   279     Corresponding Source along with the object code.  If the place to
       
   280     copy the object code is a network server, the Corresponding Source
       
   281     may be on a different server (operated by you or a third party)
       
   282     that supports equivalent copying facilities, provided you maintain
       
   283     clear directions next to the object code saying where to find the
       
   284     Corresponding Source.  Regardless of what server hosts the
       
   285     Corresponding Source, you remain obligated to ensure that it is
       
   286     available for as long as needed to satisfy these requirements.
       
   287 
       
   288     e) Convey the object code using peer-to-peer transmission, provided
       
   289     you inform other peers where the object code and Corresponding
       
   290     Source of the work are being offered to the general public at no
       
   291     charge under subsection 6d.
       
   292 
       
   293   A separable portion of the object code, whose source code is excluded
       
   294 from the Corresponding Source as a System Library, need not be
       
   295 included in conveying the object code work.
       
   296 
       
   297   A "User Product" is either (1) a "consumer product", which means any
       
   298 tangible personal property which is normally used for personal, family,
       
   299 or household purposes, or (2) anything designed or sold for incorporation
       
   300 into a dwelling.  In determining whether a product is a consumer product,
       
   301 doubtful cases shall be resolved in favor of coverage.  For a particular
       
   302 product received by a particular user, "normally used" refers to a
       
   303 typical or common use of that class of product, regardless of the status
       
   304 of the particular user or of the way in which the particular user
       
   305 actually uses, or expects or is expected to use, the product.  A product
       
   306 is a consumer product regardless of whether the product has substantial
       
   307 commercial, industrial or non-consumer uses, unless such uses represent
       
   308 the only significant mode of use of the product.
       
   309 
       
   310   "Installation Information" for a User Product means any methods,
       
   311 procedures, authorization keys, or other information required to install
       
   312 and execute modified versions of a covered work in that User Product from
       
   313 a modified version of its Corresponding Source.  The information must
       
   314 suffice to ensure that the continued functioning of the modified object
       
   315 code is in no case prevented or interfered with solely because
       
   316 modification has been made.
       
   317 
       
   318   If you convey an object code work under this section in, or with, or
       
   319 specifically for use in, a User Product, and the conveying occurs as
       
   320 part of a transaction in which the right of possession and use of the
       
   321 User Product is transferred to the recipient in perpetuity or for a
       
   322 fixed term (regardless of how the transaction is characterized), the
       
   323 Corresponding Source conveyed under this section must be accompanied
       
   324 by the Installation Information.  But this requirement does not apply
       
   325 if neither you nor any third party retains the ability to install
       
   326 modified object code on the User Product (for example, the work has
       
   327 been installed in ROM).
       
   328 
       
   329   The requirement to provide Installation Information does not include a
       
   330 requirement to continue to provide support service, warranty, or updates
       
   331 for a work that has been modified or installed by the recipient, or for
       
   332 the User Product in which it has been modified or installed.  Access to a
       
   333 network may be denied when the modification itself materially and
       
   334 adversely affects the operation of the network or violates the rules and
       
   335 protocols for communication across the network.
       
   336 
       
   337   Corresponding Source conveyed, and Installation Information provided,
       
   338 in accord with this section must be in a format that is publicly
       
   339 documented (and with an implementation available to the public in
       
   340 source code form), and must require no special password or key for
       
   341 unpacking, reading or copying.
       
   342 
       
   343   7. Additional Terms.
       
   344 
       
   345   "Additional permissions" are terms that supplement the terms of this
       
   346 License by making exceptions from one or more of its conditions.
       
   347 Additional permissions that are applicable to the entire Program shall
       
   348 be treated as though they were included in this License, to the extent
       
   349 that they are valid under applicable law.  If additional permissions
       
   350 apply only to part of the Program, that part may be used separately
       
   351 under those permissions, but the entire Program remains governed by
       
   352 this License without regard to the additional permissions.
       
   353 
       
   354   When you convey a copy of a covered work, you may at your option
       
   355 remove any additional permissions from that copy, or from any part of
       
   356 it.  (Additional permissions may be written to require their own
       
   357 removal in certain cases when you modify the work.)  You may place
       
   358 additional permissions on material, added by you to a covered work,
       
   359 for which you have or can give appropriate copyright permission.
       
   360 
       
   361   Notwithstanding any other provision of this License, for material you
       
   362 add to a covered work, you may (if authorized by the copyright holders of
       
   363 that material) supplement the terms of this License with terms:
       
   364 
       
   365     a) Disclaiming warranty or limiting liability differently from the
       
   366     terms of sections 15 and 16 of this License; or
       
   367 
       
   368     b) Requiring preservation of specified reasonable legal notices or
       
   369     author attributions in that material or in the Appropriate Legal
       
   370     Notices displayed by works containing it; or
       
   371 
       
   372     c) Prohibiting misrepresentation of the origin of that material, or
       
   373     requiring that modified versions of such material be marked in
       
   374     reasonable ways as different from the original version; or
       
   375 
       
   376     d) Limiting the use for publicity purposes of names of licensors or
       
   377     authors of the material; or
       
   378 
       
   379     e) Declining to grant rights under trademark law for use of some
       
   380     trade names, trademarks, or service marks; or
       
   381 
       
   382     f) Requiring indemnification of licensors and authors of that
       
   383     material by anyone who conveys the material (or modified versions of
       
   384     it) with contractual assumptions of liability to the recipient, for
       
   385     any liability that these contractual assumptions directly impose on
       
   386     those licensors and authors.
       
   387 
       
   388   All other non-permissive additional terms are considered "further
       
   389 restrictions" within the meaning of section 10.  If the Program as you
       
   390 received it, or any part of it, contains a notice stating that it is
       
   391 governed by this License along with a term that is a further
       
   392 restriction, you may remove that term.  If a license document contains
       
   393 a further restriction but permits relicensing or conveying under this
       
   394 License, you may add to a covered work material governed by the terms
       
   395 of that license document, provided that the further restriction does
       
   396 not survive such relicensing or conveying.
       
   397 
       
   398   If you add terms to a covered work in accord with this section, you
       
   399 must place, in the relevant source files, a statement of the
       
   400 additional terms that apply to those files, or a notice indicating
       
   401 where to find the applicable terms.
       
   402 
       
   403   Additional terms, permissive or non-permissive, may be stated in the
       
   404 form of a separately written license, or stated as exceptions;
       
   405 the above requirements apply either way.
       
   406 
       
   407   8. Termination.
       
   408 
       
   409   You may not propagate or modify a covered work except as expressly
       
   410 provided under this License.  Any attempt otherwise to propagate or
       
   411 modify it is void, and will automatically terminate your rights under
       
   412 this License (including any patent licenses granted under the third
       
   413 paragraph of section 11).
       
   414 
       
   415   However, if you cease all violation of this License, then your
       
   416 license from a particular copyright holder is reinstated (a)
       
   417 provisionally, unless and until the copyright holder explicitly and
       
   418 finally terminates your license, and (b) permanently, if the copyright
       
   419 holder fails to notify you of the violation by some reasonable means
       
   420 prior to 60 days after the cessation.
       
   421 
       
   422   Moreover, your license from a particular copyright holder is
       
   423 reinstated permanently if the copyright holder notifies you of the
       
   424 violation by some reasonable means, this is the first time you have
       
   425 received notice of violation of this License (for any work) from that
       
   426 copyright holder, and you cure the violation prior to 30 days after
       
   427 your receipt of the notice.
       
   428 
       
   429   Termination of your rights under this section does not terminate the
       
   430 licenses of parties who have received copies or rights from you under
       
   431 this License.  If your rights have been terminated and not permanently
       
   432 reinstated, you do not qualify to receive new licenses for the same
       
   433 material under section 10.
       
   434 
       
   435   9. Acceptance Not Required for Having Copies.
       
   436 
       
   437   You are not required to accept this License in order to receive or
       
   438 run a copy of the Program.  Ancillary propagation of a covered work
       
   439 occurring solely as a consequence of using peer-to-peer transmission
       
   440 to receive a copy likewise does not require acceptance.  However,
       
   441 nothing other than this License grants you permission to propagate or
       
   442 modify any covered work.  These actions infringe copyright if you do
       
   443 not accept this License.  Therefore, by modifying or propagating a
       
   444 covered work, you indicate your acceptance of this License to do so.
       
   445 
       
   446   10. Automatic Licensing of Downstream Recipients.
       
   447 
       
   448   Each time you convey a covered work, the recipient automatically
       
   449 receives a license from the original licensors, to run, modify and
       
   450 propagate that work, subject to this License.  You are not responsible
       
   451 for enforcing compliance by third parties with this License.
       
   452 
       
   453   An "entity transaction" is a transaction transferring control of an
       
   454 organization, or substantially all assets of one, or subdividing an
       
   455 organization, or merging organizations.  If propagation of a covered
       
   456 work results from an entity transaction, each party to that
       
   457 transaction who receives a copy of the work also receives whatever
       
   458 licenses to the work the party's predecessor in interest had or could
       
   459 give under the previous paragraph, plus a right to possession of the
       
   460 Corresponding Source of the work from the predecessor in interest, if
       
   461 the predecessor has it or can get it with reasonable efforts.
       
   462 
       
   463   You may not impose any further restrictions on the exercise of the
       
   464 rights granted or affirmed under this License.  For example, you may
       
   465 not impose a license fee, royalty, or other charge for exercise of
       
   466 rights granted under this License, and you may not initiate litigation
       
   467 (including a cross-claim or counterclaim in a lawsuit) alleging that
       
   468 any patent claim is infringed by making, using, selling, offering for
       
   469 sale, or importing the Program or any portion of it.
       
   470 
       
   471   11. Patents.
       
   472 
       
   473   A "contributor" is a copyright holder who authorizes use under this
       
   474 License of the Program or a work on which the Program is based.  The
       
   475 work thus licensed is called the contributor's "contributor version".
       
   476 
       
   477   A contributor's "essential patent claims" are all patent claims
       
   478 owned or controlled by the contributor, whether already acquired or
       
   479 hereafter acquired, that would be infringed by some manner, permitted
       
   480 by this License, of making, using, or selling its contributor version,
       
   481 but do not include claims that would be infringed only as a
       
   482 consequence of further modification of the contributor version.  For
       
   483 purposes of this definition, "control" includes the right to grant
       
   484 patent sublicenses in a manner consistent with the requirements of
       
   485 this License.
       
   486 
       
   487   Each contributor grants you a non-exclusive, worldwide, royalty-free
       
   488 patent license under the contributor's essential patent claims, to
       
   489 make, use, sell, offer for sale, import and otherwise run, modify and
       
   490 propagate the contents of its contributor version.
       
   491 
       
   492   In the following three paragraphs, a "patent license" is any express
       
   493 agreement or commitment, however denominated, not to enforce a patent
       
   494 (such as an express permission to practice a patent or covenant not to
       
   495 sue for patent infringement).  To "grant" such a patent license to a
       
   496 party means to make such an agreement or commitment not to enforce a
       
   497 patent against the party.
       
   498 
       
   499   If you convey a covered work, knowingly relying on a patent license,
       
   500 and the Corresponding Source of the work is not available for anyone
       
   501 to copy, free of charge and under the terms of this License, through a
       
   502 publicly available network server or other readily accessible means,
       
   503 then you must either (1) cause the Corresponding Source to be so
       
   504 available, or (2) arrange to deprive yourself of the benefit of the
       
   505 patent license for this particular work, or (3) arrange, in a manner
       
   506 consistent with the requirements of this License, to extend the patent
       
   507 license to downstream recipients.  "Knowingly relying" means you have
       
   508 actual knowledge that, but for the patent license, your conveying the
       
   509 covered work in a country, or your recipient's use of the covered work
       
   510 in a country, would infringe one or more identifiable patents in that
       
   511 country that you have reason to believe are valid.
       
   512 
       
   513   If, pursuant to or in connection with a single transaction or
       
   514 arrangement, you convey, or propagate by procuring conveyance of, a
       
   515 covered work, and grant a patent license to some of the parties
       
   516 receiving the covered work authorizing them to use, propagate, modify
       
   517 or convey a specific copy of the covered work, then the patent license
       
   518 you grant is automatically extended to all recipients of the covered
       
   519 work and works based on it.
       
   520 
       
   521   A patent license is "discriminatory" if it does not include within
       
   522 the scope of its coverage, prohibits the exercise of, or is
       
   523 conditioned on the non-exercise of one or more of the rights that are
       
   524 specifically granted under this License.  You may not convey a covered
       
   525 work if you are a party to an arrangement with a third party that is
       
   526 in the business of distributing software, under which you make payment
       
   527 to the third party based on the extent of your activity of conveying
       
   528 the work, and under which the third party grants, to any of the
       
   529 parties who would receive the covered work from you, a discriminatory
       
   530 patent license (a) in connection with copies of the covered work
       
   531 conveyed by you (or copies made from those copies), or (b) primarily
       
   532 for and in connection with specific products or compilations that
       
   533 contain the covered work, unless you entered into that arrangement,
       
   534 or that patent license was granted, prior to 28 March 2007.
       
   535 
       
   536   Nothing in this License shall be construed as excluding or limiting
       
   537 any implied license or other defenses to infringement that may
       
   538 otherwise be available to you under applicable patent law.
       
   539 
       
   540   12. No Surrender of Others' Freedom.
       
   541 
       
   542   If conditions are imposed on you (whether by court order, agreement or
       
   543 otherwise) that contradict the conditions of this License, they do not
       
   544 excuse you from the conditions of this License.  If you cannot convey a
       
   545 covered work so as to satisfy simultaneously your obligations under this
       
   546 License and any other pertinent obligations, then as a consequence you may
       
   547 not convey it at all.  For example, if you agree to terms that obligate you
       
   548 to collect a royalty for further conveying from those to whom you convey
       
   549 the Program, the only way you could satisfy both those terms and this
       
   550 License would be to refrain entirely from conveying the Program.
       
   551 
       
   552   13. Use with the GNU Affero General Public License.
       
   553 
       
   554   Notwithstanding any other provision of this License, you have
       
   555 permission to link or combine any covered work with a work licensed
       
   556 under version 3 of the GNU Affero General Public License into a single
       
   557 combined work, and to convey the resulting work.  The terms of this
       
   558 License will continue to apply to the part which is the covered work,
       
   559 but the special requirements of the GNU Affero General Public License,
       
   560 section 13, concerning interaction through a network will apply to the
       
   561 combination as such.
       
   562 
       
   563   14. Revised Versions of this License.
       
   564 
       
   565   The Free Software Foundation may publish revised and/or new versions of
       
   566 the GNU General Public License from time to time.  Such new versions will
       
   567 be similar in spirit to the present version, but may differ in detail to
       
   568 address new problems or concerns.
       
   569 
       
   570   Each version is given a distinguishing version number.  If the
       
   571 Program specifies that a certain numbered version of the GNU General
       
   572 Public License "or any later version" applies to it, you have the
       
   573 option of following the terms and conditions either of that numbered
       
   574 version or of any later version published by the Free Software
       
   575 Foundation.  If the Program does not specify a version number of the
       
   576 GNU General Public License, you may choose any version ever published
       
   577 by the Free Software Foundation.
       
   578 
       
   579   If the Program specifies that a proxy can decide which future
       
   580 versions of the GNU General Public License can be used, that proxy's
       
   581 public statement of acceptance of a version permanently authorizes you
       
   582 to choose that version for the Program.
       
   583 
       
   584   Later license versions may give you additional or different
       
   585 permissions.  However, no additional obligations are imposed on any
       
   586 author or copyright holder as a result of your choosing to follow a
       
   587 later version.
       
   588 
       
   589   15. Disclaimer of Warranty.
       
   590 
       
   591   THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
       
   592 APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
       
   593 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
       
   594 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
       
   595 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
       
   596 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
       
   597 IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
       
   598 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
       
   599 
       
   600   16. Limitation of Liability.
       
   601 
       
   602   IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
       
   603 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
       
   604 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
       
   605 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
       
   606 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
       
   607 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
       
   608 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
       
   609 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
       
   610 SUCH DAMAGES.
       
   611 
       
   612   17. Interpretation of Sections 15 and 16.
       
   613 
       
   614   If the disclaimer of warranty and limitation of liability provided
       
   615 above cannot be given local legal effect according to their terms,
       
   616 reviewing courts shall apply local law that most closely approximates
       
   617 an absolute waiver of all civil liability in connection with the
       
   618 Program, unless a warranty or assumption of liability accompanies a
       
   619 copy of the Program in return for a fee.
       
   620 
       
   621                      END OF TERMS AND CONDITIONS
       
   622 
       
   623             How to Apply These Terms to Your New Programs
       
   624 
       
   625   If you develop a new program, and you want it to be of the greatest
       
   626 possible use to the public, the best way to achieve this is to make it
       
   627 free software which everyone can redistribute and change under these terms.
       
   628 
       
   629   To do so, attach the following notices to the program.  It is safest
       
   630 to attach them to the start of each source file to most effectively
       
   631 state the exclusion of warranty; and each file should have at least
       
   632 the "copyright" line and a pointer to where the full notice is found.
       
   633 
       
   634     {one line to give the program's name and a brief idea of what it does.}
       
   635     Copyright (C) {year}  {name of author}
       
   636 
       
   637     This program is free software: you can redistribute it and/or modify
       
   638     it under the terms of the GNU General Public License as published by
       
   639     the Free Software Foundation, either version 3 of the License, or
       
   640     (at your option) any later version.
       
   641 
       
   642     This program is distributed in the hope that it will be useful,
       
   643     but WITHOUT ANY WARRANTY; without even the implied warranty of
       
   644     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
       
   645     GNU General Public License for more details.
       
   646 
       
   647     You should have received a copy of the GNU General Public License
       
   648     along with this program.  If not, see <http://www.gnu.org/licenses/>.
       
   649 
       
   650 Also add information on how to contact you by electronic and paper mail.
       
   651 
       
   652   If the program does terminal interaction, make it output a short
       
   653 notice like this when it starts in an interactive mode:
       
   654 
       
   655     {project}  Copyright (C) {year}  {fullname}
       
   656     This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
       
   657     This is free software, and you are welcome to redistribute it
       
   658     under certain conditions; type `show c' for details.
       
   659 
       
   660 The hypothetical commands `show w' and `show c' should show the appropriate
       
   661 parts of the General Public License.  Of course, your program's commands
       
   662 might be different; for a GUI interface, you would use an "about box".
       
   663 
       
   664   You should also get your employer (if you work as a programmer) or school,
       
   665 if any, to sign a "copyright disclaimer" for the program, if necessary.

   668 
       
   669   The GNU General Public License does not permit incorporating your program
       
   670 into proprietary programs.  If your program is a subroutine library, you
       
   671 may consider it more useful to permit linking proprietary applications with
       
   672 the library.  If this is what you want to do, use the GNU Lesser General
       
   673 Public License instead of this License.  But first, please read
