     2                    GNU GENERAL PUBLIC LICENSE
     3                       Version 3, 29 June 2007
     4
     5 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
     6 Everyone is permitted to copy and distribute verbatim copies
     7 of this license document, but changing it is not allowed.
     8
     9                            Preamble
     10
     11  The GNU General Public License is a free, copyleft license for
     12software and other kinds of works.
     13
     14  The licenses for most software and other practical works are designed
     15to take away your freedom to share and change the works.  By contrast,
     16the GNU General Public License is intended to guarantee your freedom to
     17share and change all versions of a program--to make sure it remains free
     18software for all its users.  We, the Free Software Foundation, use the
     19GNU General Public License for most of our software; it applies also to
     20any other work released this way by its authors.  You can apply it to
     21your programs, too.
     22
     23  When we speak of free software, we are referring to freedom, not
     24price.  Our General Public Licenses are designed to make sure that you
     25have the freedom to distribute copies of free software (and charge for
     26them if you wish), that you receive source code or can get it if you
     27want it, that you can change the software or use pieces of it in new
     28free programs, and that you know you can do these things.
     29
     30  To protect your rights, we need to prevent others from denying you
     31these rights or asking you to surrender the rights.  Therefore, you have
     32certain responsibilities if you distribute copies of the software, or if
     33you modify it: responsibilities to respect the freedom of others.
     34
     35  For example, if you distribute copies of such a program, whether
     36gratis or for a fee, you must pass on to the recipients the same
     37freedoms that you received.  You must make sure that they, too, receive
     38or can get the source code.  And you must show them these terms so they
     39know their rights.
     40
     41  Developers that use the GNU GPL protect your rights with two steps:
     42(1) assert copyright on the software, and (2) offer you this License
     43giving you legal permission to copy, distribute and/or modify it.
     44
     45  For the developers' and authors' protection, the GPL clearly explains
     46that there is no warranty for this free software.  For both users' and
     47authors' sake, the GPL requires that modified versions be marked as
     48changed, so that their problems will not be attributed erroneously to
     49authors of previous versions.
     50
     51  Some devices are designed to deny users access to install or run
     52modified versions of the software inside them, although the manufacturer
     53can do so.  This is fundamentally incompatible with the aim of
     54protecting users' freedom to change the software.  The systematic
     55pattern of such abuse occurs in the area of products for individuals to
     56use, which is precisely where it is most unacceptable.  Therefore, we
     57have designed this version of the GPL to prohibit the practice for those
     58products.  If such problems arise substantially in other domains, we
     59stand ready to extend this provision to those domains in future versions
     60of the GPL, as needed to protect the freedom of users.
     61
     62  Finally, every program is threatened constantly by software patents.
     63States should not allow patents to restrict development and use of
     64software on general-purpose computers, but in those that do, we wish to
     65avoid the special danger that patents applied to a free program could
     66make it effectively proprietary.  To prevent this, the GPL assures that
     67patents cannot be used to render the program non-free.
     68
     69  The precise terms and conditions for copying, distribution and
     70modification follow.
     71
     72                       TERMS AND CONDITIONS
     73
     74  0. Definitions.
     75
     76  "This License" refers to version 3 of the GNU General Public License.
     77
     78  "Copyright" also means copyright-like laws that apply to other kinds of
     79works, such as semiconductor masks.
     80
     81  "The Program" refers to any copyrightable work licensed under this
     82License.  Each licensee is addressed as "you".  "Licensees" and
     83"recipients" may be individuals or organizations.
     84
     85  To "modify" a work means to copy from or adapt all or part of the work
     86in a fashion requiring copyright permission, other than the making of an
     87exact copy.  The resulting work is called a "modified version" of the
     88earlier work or a work "based on" the earlier work.
     89
     90  A "covered work" means either the unmodified Program or a work based
     91on the Program.
     92
     93  To "propagate" a work means to do anything with it that, without
     94permission, would make you directly or secondarily liable for
     95infringement under applicable copyright law, except executing it on a
     96computer or modifying a private copy.  Propagation includes copying,
     97distribution (with or without modification), making available to the
     98public, and in some countries other activities as well.
     99
     100  To "convey" a work means any kind of propagation that enables other
     101parties to make or receive copies.  Mere interaction with a user through
     102a computer network, with no transfer of a copy, is not conveying.
     103
     104  An interactive user interface displays "Appropriate Legal Notices"
     105to the extent that it includes a convenient and prominently visible
     106feature that (1) displays an appropriate copyright notice, and (2)
     107tells the user that there is no warranty for the work (except to the
     108extent that warranties are provided), that licensees may convey the
     109work under this License, and how to view a copy of this License.  If
     110the interface presents a list of user commands or options, such as a
     111menu, a prominent item in the list meets this criterion.
     112
     113  1. Source Code.
     114
     115  The "source code" for a work means the preferred form of the work
     116for making modifications to it.  "Object code" means any non-source
     117form of a work.
     118
     119  A "Standard Interface" means an interface that either is an official
     120standard defined by a recognized standards body, or, in the case of
     121interfaces specified for a particular programming language, one that
     122is widely used among developers working in that language.
     123
     124  The "System Libraries" of an executable work include anything, other
     125than the work as a whole, that (a) is included in the normal form of
     126packaging a Major Component, but which is not part of that Major
     127Component, and (b) serves only to enable use of the work with that
     128Major Component, or to implement a Standard Interface for which an
     129implementation is available to the public in source code form.  A
     130"Major Component", in this context, means a major essential component
     131(kernel, window system, and so on) of the specific operating system
     132(if any) on which the executable work runs, or a compiler used to
     133produce the work, or an object code interpreter used to run it.
     134
     135  The "Corresponding Source" for a work in object code form means all
     136the source code needed to generate, install, and (for an executable
     137work) run the object code and to modify the work, including scripts to
     138control those activities.  However, it does not include the work's
     139System Libraries, or general-purpose tools or generally available free
     140programs which are used unmodified in performing those activities but
     141which are not part of the work.  For example, Corresponding Source
     142includes interface definition files associated with source files for
     143the work, and the source code for shared libraries and dynamically
     144linked subprograms that the work is specifically designed to require,
     145such as by intimate data communication or control flow between those
     146subprograms and other parts of the work.
     147
     148  The Corresponding Source need not include anything that users
     149can regenerate automatically from other parts of the Corresponding
     150Source.
     151
     152  The Corresponding Source for a work in source code form is that
     153same work.
     154
     155  2. Basic Permissions.
     156
     157  All rights granted under this License are granted for the term of
     158copyright on the Program, and are irrevocable provided the stated
     159conditions are met.  This License explicitly affirms your unlimited
     160permission to run the unmodified Program.  The output from running a
     161covered work is covered by this License only if the output, given its
     162content, constitutes a covered work.  This License acknowledges your
     163rights of fair use or other equivalent, as provided by copyright law.
     164
     165  You may make, run and propagate covered works that you do not
     166convey, without conditions so long as your license otherwise remains
     167in force.  You may convey covered works to others for the sole purpose
     168of having them make modifications exclusively for you, or provide you
     169with facilities for running those works, provided that you comply with
     170the terms of this License in conveying all material for which you do
     171not control copyright.  Those thus making or running the covered works
     172for you must do so exclusively on your behalf, under your direction
     173and control, on terms that prohibit them from making any copies of
     174your copyrighted material outside their relationship with you.
     175
     176  Conveying under any other circumstances is permitted solely under
     177the conditions stated below.  Sublicensing is not allowed; section 10
     178makes it unnecessary.
     179
     180  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
     181
     182  No covered work shall be deemed part of an effective technological
     183measure under any applicable law fulfilling obligations under article
     18411 of the WIPO copyright treaty adopted on 20 December 1996, or
     185similar laws prohibiting or restricting circumvention of such
     186measures.
     187
     188  When you convey a covered work, you waive any legal power to forbid
     189circumvention of technological measures to the extent such circumvention
     190is effected by exercising rights under this License with respect to
     191the covered work, and you disclaim any intention to limit operation or
     192modification of the work as a means of enforcing, against the work's
     193users, your or third parties' legal rights to forbid circumvention of
     194technological measures.
     195
     196  4. Conveying Verbatim Copies.
     197
     198  You may convey verbatim copies of the Program's source code as you
     199receive it, in any medium, provided that you conspicuously and
     200appropriately publish on each copy an appropriate copyright notice;
     201keep intact all notices stating that this License and any
     202non-permissive terms added in accord with section 7 apply to the code;
     203keep intact all notices of the absence of any warranty; and give all
     204recipients a copy of this License along with the Program.
     205
     206  You may charge any price or no price for each copy that you convey,
     207and you may offer support or warranty protection for a fee.
     208
     209  5. Conveying Modified Source Versions.
     210
     211  You may convey a work based on the Program, or the modifications to
     212produce it from the Program, in the form of source code under the
     213terms of section 4, provided that you also meet all of these conditions:
     214
     215    a) The work must carry prominent notices stating that you modified
     216    it, and giving a relevant date.
     217
     218    b) The work must carry prominent notices stating that it is
     219    released under this License and any conditions added under section
     220    7.  This requirement modifies the requirement in section 4 to
     221    "keep intact all notices".
     222
     223    c) You must license the entire work, as a whole, under this
     224    License to anyone who comes into possession of a copy.  This
     225    License will therefore apply, along with any applicable section 7
     226    additional terms, to the whole of the work, and all its parts,
     227    regardless of how they are packaged.  This License gives no
     228    permission to license the work in any other way, but it does not
     229    invalidate such permission if you have separately received it.
     230
     231    d) If the work has interactive user interfaces, each must display
     232    Appropriate Legal Notices; however, if the Program has interactive
     233    interfaces that do not display Appropriate Legal Notices, your
     234    work need not make them do so.
     235
     236  A compilation of a covered work with other separate and independent
     237works, which are not by their nature extensions of the covered work,
     238and which are not combined with it such as to form a larger program,
     239in or on a volume of a storage or distribution medium, is called an
     240"aggregate" if the compilation and its resulting copyright are not
     241used to limit the access or legal rights of the compilation's users
     242beyond what the individual works permit.  Inclusion of a covered work
     243in an aggregate does not cause this License to apply to the other
     244parts of the aggregate.
     245
     246  6. Conveying Non-Source Forms.
     247
     248  You may convey a covered work in object code form under the terms
     249of sections 4 and 5, provided that you also convey the
     250machine-readable Corresponding Source under the terms of this License,
     251in one of these ways:
     252
     253    a) Convey the object code in, or embodied in, a physical product
     254    (including a physical distribution medium), accompanied by the
     255    Corresponding Source fixed on a durable physical medium
     256    customarily used for software interchange.
     257
     258    b) Convey the object code in, or embodied in, a physical product
     259    (including a physical distribution medium), accompanied by a
     260    written offer, valid for at least three years and valid for as
     261    long as you offer spare parts or customer support for that product
     262    model, to give anyone who possesses the object code either (1) a
     263    copy of the Corresponding Source for all the software in the
     264    product that is covered by this License, on a durable physical
     265    medium customarily used for software interchange, for a price no
     266    more than your reasonable cost of physically performing this
     267    conveying of source, or (2) access to copy the
     268    Corresponding Source from a network server at no charge.
     269
     270    c) Convey individual copies of the object code with a copy of the
     271    written offer to provide the Corresponding Source.  This
     272    alternative is allowed only occasionally and noncommercially, and
     273    only if you received the object code with such an offer, in accord
     274    with subsection 6b.
     275
     276    d) Convey the object code by offering access from a designated
     277    place (gratis or for a charge), and offer equivalent access to the
     278    Corresponding Source in the same way through the same place at no
     279    further charge.  You need not require recipients to copy the
     280    Corresponding Source along with the object code.  If the place to
     281    copy the object code is a network server, the Corresponding Source
     282    may be on a different server (operated by you or a third party)
     283    that supports equivalent copying facilities, provided you maintain
     284    clear directions next to the object code saying where to find the
     285    Corresponding Source.  Regardless of what server hosts the
     286    Corresponding Source, you remain obligated to ensure that it is
     287    available for as long as needed to satisfy these requirements.
     288
     289    e) Convey the object code using peer-to-peer transmission, provided
     290    you inform other peers where the object code and Corresponding
     291    Source of the work are being offered to the general public at no
     292    charge under subsection 6d.
     293
     294  A separable portion of the object code, whose source code is excluded
     295from the Corresponding Source as a System Library, need not be
     296included in conveying the object code work.
     297
     298  A "User Product" is either (1) a "consumer product", which means any
     299tangible personal property which is normally used for personal, family,
     300or household purposes, or (2) anything designed or sold for incorporation
     301into a dwelling.  In determining whether a product is a consumer product,
     302doubtful cases shall be resolved in favor of coverage.  For a particular
     303product received by a particular user, "normally used" refers to a
     304typical or common use of that class of product, regardless of the status
     305of the particular user or of the way in which the particular user
     306actually uses, or expects or is expected to use, the product.  A product
     307is a consumer product regardless of whether the product has substantial
     308commercial, industrial or non-consumer uses, unless such uses represent
     309the only significant mode of use of the product.
     310
     311  "Installation Information" for a User Product means any methods,
     312procedures, authorization keys, or other information required to install
     313and execute modified versions of a covered work in that User Product from
     314a modified version of its Corresponding Source.  The information must
     315suffice to ensure that the continued functioning of the modified object
     316code is in no case prevented or interfered with solely because
     317modification has been made.
     318
     319  If you convey an object code work under this section in, or with, or
     320specifically for use in, a User Product, and the conveying occurs as
     321part of a transaction in which the right of possession and use of the
     322User Product is transferred to the recipient in perpetuity or for a
     323fixed term (regardless of how the transaction is characterized), the
     324Corresponding Source conveyed under this section must be accompanied
     325by the Installation Information.  But this requirement does not apply
     326if neither you nor any third party retains the ability to install
     327modified object code on the User Product (for example, the work has
     328been installed in ROM).
     329
     330  The requirement to provide Installation Information does not include a
     331requirement to continue to provide support service, warranty, or updates
     332for a work that has been modified or installed by the recipient, or for
     333the User Product in which it has been modified or installed.  Access to a
     334network may be denied when the modification itself materially and
     335adversely affects the operation of the network or violates the rules and
     336protocols for communication across the network.
     337
     338  Corresponding Source conveyed, and Installation Information provided,
     339in accord with this section must be in a format that is publicly
     340documented (and with an implementation available to the public in
     341source code form), and must require no special password or key for
     342unpacking, reading or copying.
     343
     344  7. Additional Terms.
     345
     346  "Additional permissions" are terms that supplement the terms of this
     347License by making exceptions from one or more of its conditions.
     348Additional permissions that are applicable to the entire Program shall
     349be treated as though they were included in this License, to the extent
     350that they are valid under applicable law.  If additional permissions
     351apply only to part of the Program, that part may be used separately
     352under those permissions, but the entire Program remains governed by
     353this License without regard to the additional permissions.
     354
     355  When you convey a copy of a covered work, you may at your option
     356remove any additional permissions from that copy, or from any part of
     357it.  (Additional permissions may be written to require their own
     358removal in certain cases when you modify the work.)  You may place
     359additional permissions on material, added by you to a covered work,
     360for which you have or can give appropriate copyright permission.
     361
     362  Notwithstanding any other provision of this License, for material you
     363add to a covered work, you may (if authorized by the copyright holders of
     364that material) supplement the terms of this License with terms:
     365
     366    a) Disclaiming warranty or limiting liability differently from the
     367    terms of sections 15 and 16 of this License; or
     368
     369    b) Requiring preservation of specified reasonable legal notices or
     370    author attributions in that material or in the Appropriate Legal
     371    Notices displayed by works containing it; or
     372
     373    c) Prohibiting misrepresentation of the origin of that material, or
     374    requiring that modified versions of such material be marked in
     375    reasonable ways as different from the original version; or
     376
     377    d) Limiting the use for publicity purposes of names of licensors or
     378    authors of the material; or
     379
     380    e) Declining to grant rights under trademark law for use of some
     381    trade names, trademarks, or service marks; or
     382
     383    f) Requiring indemnification of licensors and authors of that
     384    material by anyone who conveys the material (or modified versions of
     385    it) with contractual assumptions of liability to the recipient, for
     386    any liability that these contractual assumptions directly impose on
     387    those licensors and authors.
     388
     389  All other non-permissive additional terms are considered "further
     390restrictions" within the meaning of section 10.  If the Program as you
     391received it, or any part of it, contains a notice stating that it is
     392governed by this License along with a term that is a further
     393restriction, you may remove that term.  If a license document contains
     394a further restriction but permits relicensing or conveying under this
     395License, you may add to a covered work material governed by the terms
     396of that license document, provided that the further restriction does
     397not survive such relicensing or conveying.
     398
     399  If you add terms to a covered work in accord with this section, you
     400must place, in the relevant source files, a statement of the
     401additional terms that apply to those files, or a notice indicating
     402where to find the applicable terms.
     403
     404  Additional terms, permissive or non-permissive, may be stated in the
     405form of a separately written license, or stated as exceptions;
     406the above requirements apply either way.
     407
     408  8. Termination.
     409
     410  You may not propagate or modify a covered work except as expressly
     411provided under this License.  Any attempt otherwise to propagate or
     412modify it is void, and will automatically terminate your rights under
     413this License (including any patent licenses granted under the third
     414paragraph of section 11).
     415
     416  However, if you cease all violation of this License, then your
     417license from a particular copyright holder is reinstated (a)
     418provisionally, unless and until the copyright holder explicitly and
     419finally terminates your license, and (b) permanently, if the copyright
     420holder fails to notify you of the violation by some reasonable means
     421prior to 60 days after the cessation.
     422
     423  Moreover, your license from a particular copyright holder is
     424reinstated permanently if the copyright holder notifies you of the
     425violation by some reasonable means, this is the first time you have
     426received notice of violation of this License (for any work) from that
     427copyright holder, and you cure the violation prior to 30 days after
     428your receipt of the notice.
     429
     430  Termination of your rights under this section does not terminate the
     431licenses of parties who have received copies or rights from you under
     432this License.  If your rights have been terminated and not permanently
     433reinstated, you do not qualify to receive new licenses for the same
     434material under section 10.
     435
     436  9. Acceptance Not Required for Having Copies.
     437
     438  You are not required to accept this License in order to receive or
     439run a copy of the Program.  Ancillary propagation of a covered work
     440occurring solely as a consequence of using peer-to-peer transmission
     441to receive a copy likewise does not require acceptance.  However,
     442nothing other than this License grants you permission to propagate or
     443modify any covered work.  These actions infringe copyright if you do
     444not accept this License.  Therefore, by modifying or propagating a
     445covered work, you indicate your acceptance of this License to do so.
     446
     447  10. Automatic Licensing of Downstream Recipients.
     448
     449  Each time you convey a covered work, the recipient automatically
     450receives a license from the original licensors, to run, modify and
     451propagate that work, subject to this License.  You are not responsible
     452for enforcing compliance by third parties with this License.
     453
     454  An "entity transaction" is a transaction transferring control of an
     455organization, or substantially all assets of one, or subdividing an
     456organization, or merging organizations.  If propagation of a covered
     457work results from an entity transaction, each party to that
     458transaction who receives a copy of the work also receives whatever
     459licenses to the work the party's predecessor in interest had or could
     460give under the previous paragraph, plus a right to possession of the
     461Corresponding Source of the work from the predecessor in interest, if
     462the predecessor has it or can get it with reasonable efforts.
     463
     464  You may not impose any further restrictions on the exercise of the
     465rights granted or affirmed under this License.  For example, you may
     466not impose a license fee, royalty, or other charge for exercise of
     467rights granted under this License, and you may not initiate litigation
     468(including a cross-claim or counterclaim in a lawsuit) alleging that
     469any patent claim is infringed by making, using, selling, offering for
     470sale, or importing the Program or any portion of it.
     471
     472  11. Patents.
     473
     474  A "contributor" is a copyright holder who authorizes use under this
     475License of the Program or a work on which the Program is based.  The
     476work thus licensed is called the contributor's "contributor version".
     477
     478  A contributor's "essential patent claims" are all patent claims
     479owned or controlled by the contributor, whether already acquired or
     480hereafter acquired, that would be infringed by some manner, permitted
     481by this License, of making, using, or selling its contributor version,
     482but do not include claims that would be infringed only as a
     483consequence of further modification of the contributor version.  For
     484purposes of this definition, "control" includes the right to grant
     485patent sublicenses in a manner consistent with the requirements of
     486this License.
     487
     488  Each contributor grants you a non-exclusive, worldwide, royalty-free
     489patent license under the contributor's essential patent claims, to
     490make, use, sell, offer for sale, import and otherwise run, modify and
     491propagate the contents of its contributor version.
     492
     493  In the following three paragraphs, a "patent license" is any express
     494agreement or commitment, however denominated, not to enforce a patent
     495(such as an express permission to practice a patent or covenant not to
     496sue for patent infringement).  To "grant" such a patent license to a
     497party means to make such an agreement or commitment not to enforce a
     498patent against the party.
     499
     500  If you convey a covered work, knowingly relying on a patent license,
     501and the Corresponding Source of the work is not available for anyone
     502to copy, free of charge and under the terms of this License, through a
     503publicly available network server or other readily accessible means,
     504then you must either (1) cause the Corresponding Source to be so
     505available, or (2) arrange to deprive yourself of the benefit of the
     506patent license for this particular work, or (3) arrange, in a manner
     507consistent with the requirements of this License, to extend the patent
     508license to downstream recipients.  "Knowingly relying" means you have
     509actual knowledge that, but for the patent license, your conveying the
     510covered work in a country, or your recipient's use of the covered work
     511in a country, would infringe one or more identifiable patents in that
     512country that you have reason to believe are valid.
     513
     514  If, pursuant to or in connection with a single transaction or
     515arrangement, you convey, or propagate by procuring conveyance of, a
     516covered work, and grant a patent license to some of the parties
     517receiving the covered work authorizing them to use, propagate, modify
     518or convey a specific copy of the covered work, then the patent license
     519you grant is automatically extended to all recipients of the covered
     520work and works based on it.
     521
     522  A patent license is "discriminatory" if it does not include within
     523the scope of its coverage, prohibits the exercise of, or is
     524conditioned on the non-exercise of one or more of the rights that are
     525specifically granted under this License.  You may not convey a covered
     526work if you are a party to an arrangement with a third party that is
     527in the business of distributing software, under which you make payment
     528to the third party based on the extent of your activity of conveying
     529the work, and under which the third party grants, to any of the
     530parties who would receive the covered work from you, a discriminatory
     531patent license (a) in connection with copies of the covered work
     532conveyed by you (or copies made from those copies), or (b) primarily
     533for and in connection with specific products or compilations that
     534contain the covered work, unless you entered into that arrangement,
     535or that patent license was granted, prior to 28 March 2007.
     536
     537  Nothing in this License shall be construed as excluding or limiting
     538any implied license or other defenses to infringement that may
     539otherwise be available to you under applicable patent law.
     540
     541  12. No Surrender of Others' Freedom.
     542
     543  If conditions are imposed on you (whether by court order, agreement or
     544otherwise) that contradict the conditions of this License, they do not
     545excuse you from the conditions of this License.  If you cannot convey a
     546covered work so as to satisfy simultaneously your obligations under this
     547License and any other pertinent obligations, then as a consequence you may
     548not convey it at all.  For example, if you agree to terms that obligate you
     549to collect a royalty for further conveying from those to whom you convey
     550the Program, the only way you could satisfy both those terms and this
     551License would be to refrain entirely from conveying the Program.
     552
     553  13. Use with the GNU Affero General Public License.
     554
     555  Notwithstanding any other provision of this License, you have
     556permission to link or combine any covered work with a work licensed
     557under version 3 of the GNU Affero General Public License into a single
     558combined work, and to convey the resulting work.  The terms of this
     559License will continue to apply to the part which is the covered work,
     560but the special requirements of the GNU Affero General Public License,
     561section 13, concerning interaction through a network will apply to the
     562combination as such.
     563
     564  14. Revised Versions of this License.
     565
     566  The Free Software Foundation may publish revised and/or new versions of
     567the GNU General Public License from time to time.  Such new versions will
     568be similar in spirit to the present version, but may differ in detail to
     569address new problems or concerns.
     570
     571  Each version is given a distinguishing version number.  If the
     572Program specifies that a certain numbered version of the GNU General
     573Public License "or any later version" applies to it, you have the
     574option of following the terms and conditions either of that numbered
     575version or of any later version published by the Free Software
     576Foundation.  If the Program does not specify a version number of the
     577GNU General Public License, you may choose any version ever published
     578by the Free Software Foundation.
     579
     580  If the Program specifies that a proxy can decide which future
     581versions of the GNU General Public License can be used, that proxy's
     582public statement of acceptance of a version permanently authorizes you
     583to choose that version for the Program.
     584
     585  Later license versions may give you additional or different
     586permissions.  However, no additional obligations are imposed on any
     587author or copyright holder as a result of your choosing to follow a
     588later version.
     589
     590  15. Disclaimer of Warranty.
     591
     592  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
     593APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
     594HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
     595OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
     596THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
     597PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
     598IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
     599ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
     600
     601  16. Limitation of Liability.
     602
     603  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
     604WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
     605THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
     606GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
     607USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
     608DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
     609PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
     610EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
     611SUCH DAMAGES.
     612
     613  17. Interpretation of Sections 15 and 16.
     614
     615  If the disclaimer of warranty and limitation of liability provided
     616above cannot be given local legal effect according to their terms,
     617reviewing courts shall apply local law that most closely approximates
     618an absolute waiver of all civil liability in connection with the
     619Program, unless a warranty or assumption of liability accompanies a
     620copy of the Program in return for a fee.
     621
     622                     END OF TERMS AND CONDITIONS
     623
     624            How to Apply These Terms to Your New Programs
     625
     626  If you develop a new program, and you want it to be of the greatest
     627possible use to the public, the best way to achieve this is to make it
     628free software which everyone can redistribute and change under these terms.
     629
     630  To do so, attach the following notices to the program.  It is safest
     631to attach them to the start of each source file to most effectively
     632state the exclusion of warranty; and each file should have at least
     633the "copyright" line and a pointer to where the full notice is found.
     634
     635    <one line to give the program's name and a brief idea of what it does.>
     636    Copyright (C) <year>  <name of author>
     637
     638    This program is free software: you can redistribute it and/or modify
     639    it under the terms of the GNU General Public License as published by
     640    the Free Software Foundation, either version 3 of the License, or
     641    (at your option) any later version.
     642
     643    This program is distributed in the hope that it will be useful,
     644    but WITHOUT ANY WARRANTY; without even the implied warranty of
     645    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
     646    GNU General Public License for more details.
     647
     648    You should have received a copy of the GNU General Public License
     649    along with this program.  If not, see <http://www.gnu.org/licenses/>.
     650
     651Also add information on how to contact you by electronic and paper mail.
     652
     653  If the program does terminal interaction, make it output a short
     654notice like this when it starts in an interactive mode:
     655
     656    <program>  Copyright (C) <year>  <name of author>
     657    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
     658    This is free software, and you are welcome to redistribute it
     659    under certain conditions; type `show c' for details.
     660
     661The hypothetical commands `show w' and `show c' should show the appropriate
     662parts of the General Public License.  Of course, your program's commands
     663might be different; for a GUI interface, you would use an "about box".
     664
     665  You should also get your employer (if you work as a programmer) or school,
     666if any, to sign a "copyright disclaimer" for the program, if necessary.
     667For more information on this, and how to apply and follow the GNU GPL, see
     668<http://www.gnu.org/licenses/>.
     669
     670  The GNU General Public License does not permit incorporating your program
     671into proprietary programs.  If your program is a subroutine library, you
     672may consider it more useful to permit linking proprietary applications with
     673the library.  If this is what you want to do, use the GNU Lesser General
     674Public License instead of this License.  But first, please read
     675<http://www.gnu.org/philosophy/why-not-lgpl.html>.
