    21 \renewcommand{\abstractname}{Preamble}

    22 \begin{abstract}

    23 The GNU General Public License is a free, copyleft license for

    24 software and other kinds of works.

    25

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

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

    28 the GNU General Public License is intended to guarantee your freedom to

    29 share and change all versions of a program--to make sure it remains free

    30 software for all its users.  We, the Free Software Foundation, use the

    31 GNU General Public License for most of our software; it applies also to

    32 any other work released this way by its authors.  You can apply it to

    33 your programs, too.

    34

    35 When we speak of free software, we are referring to freedom, not

    36 price.  Our General Public Licenses are designed to make sure that you

    37 have the freedom to distribute copies of free software (and charge for

    38 them if you wish), that you receive source code or can get it if you

    39 want it, that you can change the software or use pieces of it in new

    40 free programs, and that you know you can do these things.

    41

    42 To protect your rights, we need to prevent others from denying you

    43 these rights or asking you to surrender the rights.  Therefore, you have

    44 certain responsibilities if you distribute copies of the software, or if

    45 you modify it: responsibilities to respect the freedom of others.

    46

    47 For example, if you distribute copies of such a program, whether

    48 gratis or for a fee, you must pass on to the recipients the same

    49 freedoms that you received.  You must make sure that they, too, receive

    50 or can get the source code.  And you must show them these terms so they

    51 know their rights.

    52

    53 Developers that use the GNU GPL protect your rights with two steps:

    54 (1) assert copyright on the software, and (2) offer you this License

    55 giving you legal permission to copy, distribute and/or modify it.

    56

    57 For the developers' and authors' protection, the GPL clearly explains

    58 that there is no warranty for this free software.  For both users' and

    59 authors' sake, the GPL requires that modified versions be marked as

    60 changed, so that their problems will not be attributed erroneously to

    61 authors of previous versions.

    62

    63 Some devices are designed to deny users access to install or run

    64 modified versions of the software inside them, although the manufacturer

    65 can do so.  This is fundamentally incompatible with the aim of

    66 protecting users' freedom to change the software.  The systematic

    67 pattern of such abuse occurs in the area of products for individuals to

    68 use, which is precisely where it is most unacceptable.  Therefore, we

    69 have designed this version of the GPL to prohibit the practice for those

    70 products.  If such problems arise substantially in other domains, we

    71 stand ready to extend this provision to those domains in future versions

    72 of the GPL, as needed to protect the freedom of users.

    73

    74 Finally, every program is threatened constantly by software patents.

    75 States should not allow patents to restrict development and use of

    76 software on general-purpose computers, but in those that do, we wish to

    77 avoid the special danger that patents applied to a free program could

    78 make it effectively proprietary.  To prevent this, the GPL assures that

    79 patents cannot be used to render the program non-free.

    80

    81 The precise terms and conditions for copying, distribution and

    82 modification follow.

    86 {\Large \sc Terms and Conditions}

    87 \end{center}

    89

    90 \begin{enumerate}

    91

    92 \addtocounter{enumi}{-1}

    93

    94 \item Definitions.

    95

    96 This License'' refers to version 3 of the GNU General Public License.

    97

    98 Copyright'' also means copyright-like laws that apply to other kinds of

    99 works, such as semiconductor masks.

   100

   101 The Program'' refers to any copyrightable work licensed under this

   102 License.  Each licensee is addressed as you''.  Licensees'' and

   103 recipients'' may be individuals or organizations.

   104

   105 To modify'' a work means to copy from or adapt all or part of the work

   106 in a fashion requiring copyright permission, other than the making of an

   107 exact copy.  The resulting work is called a modified version'' of the

   108 earlier work or a work based on'' the earlier work.

   109

   110 A covered work'' means either the unmodified Program or a work based

   111 on the Program.

   112

   113 To propagate'' a work means to do anything with it that, without

   114 permission, would make you directly or secondarily liable for

   115 infringement under applicable copyright law, except executing it on a

   116 computer or modifying a private copy.  Propagation includes copying,

   117 distribution (with or without modification), making available to the

   118 public, and in some countries other activities as well.

   119

   120 To convey'' a work means any kind of propagation that enables other

   121 parties to make or receive copies.  Mere interaction with a user through

   122 a computer network, with no transfer of a copy, is not conveying.

   123

   124 An interactive user interface displays Appropriate Legal Notices''

   125 to the extent that it includes a convenient and prominently visible

   126 feature that (1) displays an appropriate copyright notice, and (2)

   127 tells the user that there is no warranty for the work (except to the

   128 extent that warranties are provided), that licensees may convey the

   129 work under this License, and how to view a copy of this License.  If

   130 the interface presents a list of user commands or options, such as a

   131 menu, a prominent item in the list meets this criterion.

   132

   133 \item Source Code.

   134

   135 The source code'' for a work means the preferred form of the work

   136 for making modifications to it.  Object code'' means any non-source

   137 form of a work.

   138

   139 A Standard Interface'' means an interface that either is an official

   140 standard defined by a recognized standards body, or, in the case of

   141 interfaces specified for a particular programming language, one that

   142 is widely used among developers working in that language.

   143

   144 The System Libraries'' of an executable work include anything, other

   145 than the work as a whole, that (a) is included in the normal form of

   146 packaging a Major Component, but which is not part of that Major

   147 Component, and (b) serves only to enable use of the work with that

   148 Major Component, or to implement a Standard Interface for which an

   149 implementation is available to the public in source code form.  A

   150 Major Component'', in this context, means a major essential component

   151 (kernel, window system, and so on) of the specific operating system

   152 (if any) on which the executable work runs, or a compiler used to

   153 produce the work, or an object code interpreter used to run it.

   154

   155 The Corresponding Source'' for a work in object code form means all

   156 the source code needed to generate, install, and (for an executable

   157 work) run the object code and to modify the work, including scripts to

   158 control those activities.  However, it does not include the work's

   159 System Libraries, or general-purpose tools or generally available free

   160 programs which are used unmodified in performing those activities but

   161 which are not part of the work.  For example, Corresponding Source

   162 includes interface definition files associated with source files for

   163 the work, and the source code for shared libraries and dynamically

   164 linked subprograms that the work is specifically designed to require,

   165 such as by intimate data communication or control flow between those

   166 subprograms and other parts of the work.

   167

   168 The Corresponding Source need not include anything that users

   169 can regenerate automatically from other parts of the Corresponding

   170 Source.

   171

   172 The Corresponding Source for a work in source code form is that

   173 same work.

   174

   175 \item Basic Permissions.

   176

   177 All rights granted under this License are granted for the term of

   178 copyright on the Program, and are irrevocable provided the stated

   179 conditions are met.  This License explicitly affirms your unlimited

   180 permission to run the unmodified Program.  The output from running a

   181 covered work is covered by this License only if the output, given its

   182 content, constitutes a covered work.  This License acknowledges your

   183 rights of fair use or other equivalent, as provided by copyright law.

   184

   185 You may make, run and propagate covered works that you do not

   186 convey, without conditions so long as your license otherwise remains

   187 in force.  You may convey covered works to others for the sole purpose

   188 of having them make modifications exclusively for you, or provide you

   189 with facilities for running those works, provided that you comply with

   190 the terms of this License in conveying all material for which you do

   191 not control copyright.  Those thus making or running the covered works

   192 for you must do so exclusively on your behalf, under your direction

   193 and control, on terms that prohibit them from making any copies of

   194 your copyrighted material outside their relationship with you.

   195

   196 Conveying under any other circumstances is permitted solely under

   197 the conditions stated below.  Sublicensing is not allowed; section 10

   198 makes it unnecessary.

   199

   200 \item Protecting Users' Legal Rights From Anti-Circumvention Law.

   201

   202 No covered work shall be deemed part of an effective technological

   203 measure under any applicable law fulfilling obligations under article

   204 11 of the WIPO copyright treaty adopted on 20 December 1996, or

   205 similar laws prohibiting or restricting circumvention of such

   206 measures.

   207

   208 When you convey a covered work, you waive any legal power to forbid

   209 circumvention of technological measures to the extent such circumvention

   210 is effected by exercising rights under this License with respect to

   211 the covered work, and you disclaim any intention to limit operation or

   212 modification of the work as a means of enforcing, against the work's

   213 users, your or third parties' legal rights to forbid circumvention of

   214 technological measures.

   215

   216 \item Conveying Verbatim Copies.

   217

   218 You may convey verbatim copies of the Program's source code as you

   219 receive it, in any medium, provided that you conspicuously and

   220 appropriately publish on each copy an appropriate copyright notice;

   221 keep intact all notices stating that this License and any

   222 non-permissive terms added in accord with section 7 apply to the code;

   223 keep intact all notices of the absence of any warranty; and give all

   224 recipients a copy of this License along with the Program.

   225

   226 You may charge any price or no price for each copy that you convey,

   227 and you may offer support or warranty protection for a fee.

   228

   229 \item Conveying Modified Source Versions.

   230

   231 You may convey a work based on the Program, or the modifications to

   232 produce it from the Program, in the form of source code under the

   233 terms of section 4, provided that you also meet all of these conditions:

   234   \begin{enumerate}

   235   \item The work must carry prominent notices stating that you modified

   236   it, and giving a relevant date.

   237

   238   \item The work must carry prominent notices stating that it is

   239   released under this License and any conditions added under section

   240   7.  This requirement modifies the requirement in section 4 to

   241   keep intact all notices''.

   242

   243   \item You must license the entire work, as a whole, under this

   244   License to anyone who comes into possession of a copy.  This

   245   License will therefore apply, along with any applicable section 7

   246   additional terms, to the whole of the work, and all its parts,

   247   regardless of how they are packaged.  This License gives no

   248   permission to license the work in any other way, but it does not

   249   invalidate such permission if you have separately received it.

   250

   251   \item If the work has interactive user interfaces, each must display

   252   Appropriate Legal Notices; however, if the Program has interactive

   253   interfaces that do not display Appropriate Legal Notices, your

   254   work need not make them do so.

   255 \end{enumerate}

   256 A compilation of a covered work with other separate and independent

   257 works, which are not by their nature extensions of the covered work,

   258 and which are not combined with it such as to form a larger program,

   259 in or on a volume of a storage or distribution medium, is called an

   260 aggregate'' if the compilation and its resulting copyright are not

   261 used to limit the access or legal rights of the compilation's users

   262 beyond what the individual works permit.  Inclusion of a covered work

   263 in an aggregate does not cause this License to apply to the other

   264 parts of the aggregate.

   265

   266 \item Conveying Non-Source Forms.

   267

   268 You may convey a covered work in object code form under the terms

   269 of sections 4 and 5, provided that you also convey the

   270 machine-readable Corresponding Source under the terms of this License,

   271 in one of these ways:

   272   \begin{enumerate}

   273   \item Convey the object code in, or embodied in, a physical product

   274   (including a physical distribution medium), accompanied by the

   275   Corresponding Source fixed on a durable physical medium

   276   customarily used for software interchange.

   277

   278   \item Convey the object code in, or embodied in, a physical product

   279   (including a physical distribution medium), accompanied by a

   280   written offer, valid for at least three years and valid for as

   281   long as you offer spare parts or customer support for that product

   282   model, to give anyone who possesses the object code either (1) a

   283   copy of the Corresponding Source for all the software in the

   284   product that is covered by this License, on a durable physical

   285   medium customarily used for software interchange, for a price no

   286   more than your reasonable cost of physically performing this

   287   conveying of source, or (2) access to copy the

   288   Corresponding Source from a network server at no charge.

   289

   290   \item Convey individual copies of the object code with a copy of the

   291   written offer to provide the Corresponding Source.  This

   292   alternative is allowed only occasionally and noncommercially, and

   293   only if you received the object code with such an offer, in accord

   294   with subsection 6b.

   295

   296   \item Convey the object code by offering access from a designated

   297   place (gratis or for a charge), and offer equivalent access to the

   298   Corresponding Source in the same way through the same place at no

   299   further charge.  You need not require recipients to copy the

   300   Corresponding Source along with the object code.  If the place to

   301   copy the object code is a network server, the Corresponding Source

   302   may be on a different server (operated by you or a third party)

   303   that supports equivalent copying facilities, provided you maintain

   304   clear directions next to the object code saying where to find the

   305   Corresponding Source.  Regardless of what server hosts the

   306   Corresponding Source, you remain obligated to ensure that it is

   307   available for as long as needed to satisfy these requirements.

   308

   309   \item Convey the object code using peer-to-peer transmission, provided

   310   you inform other peers where the object code and Corresponding

   311   Source of the work are being offered to the general public at no

   312   charge under subsection 6d.

   313   \end{enumerate}

   314

   315 A separable portion of the object code, whose source code is excluded

   316 from the Corresponding Source as a System Library, need not be

   317 included in conveying the object code work.

   318

   319 A User Product'' is either (1) a consumer product'', which means any

   320 tangible personal property which is normally used for personal, family,

   321 or household purposes, or (2) anything designed or sold for incorporation

   322 into a dwelling.  In determining whether a product is a consumer product,

   323 doubtful cases shall be resolved in favor of coverage.  For a particular

   324 product received by a particular user, normally used'' refers to a

   325 typical or common use of that class of product, regardless of the status

   326 of the particular user or of the way in which the particular user

   327 actually uses, or expects or is expected to use, the product.  A product

   328 is a consumer product regardless of whether the product has substantial

   329 commercial, industrial or non-consumer uses, unless such uses represent

   330 the only significant mode of use of the product.

   331

   332 Installation Information'' for a User Product means any methods,

   333 procedures, authorization keys, or other information required to install

   334 and execute modified versions of a covered work in that User Product from

   335 a modified version of its Corresponding Source.  The information must

   336 suffice to ensure that the continued functioning of the modified object

   337 code is in no case prevented or interfered with solely because

   338 modification has been made.

   339

   340 If you convey an object code work under this section in, or with, or

   341 specifically for use in, a User Product, and the conveying occurs as

   342 part of a transaction in which the right of possession and use of the

   343 User Product is transferred to the recipient in perpetuity or for a

   344 fixed term (regardless of how the transaction is characterized), the

   345 Corresponding Source conveyed under this section must be accompanied

   346 by the Installation Information.  But this requirement does not apply

   347 if neither you nor any third party retains the ability to install

   348 modified object code on the User Product (for example, the work has

   349 been installed in ROM).

   350

   351 The requirement to provide Installation Information does not include a

   352 requirement to continue to provide support service, warranty, or updates

   353 for a work that has been modified or installed by the recipient, or for

   354 the User Product in which it has been modified or installed.  Access to a

   355 network may be denied when the modification itself materially and

   356 adversely affects the operation of the network or violates the rules and

   357 protocols for communication across the network.

   358

   359 Corresponding Source conveyed, and Installation Information provided,

   360 in accord with this section must be in a format that is publicly

   361 documented (and with an implementation available to the public in

   362 source code form), and must require no special password or key for

   363 unpacking, reading or copying.

   364

   365 \item Additional Terms.

   366

   367 Additional permissions'' are terms that supplement the terms of this

   368 License by making exceptions from one or more of its conditions.

   369 Additional permissions that are applicable to the entire Program shall

   370 be treated as though they were included in this License, to the extent

   371 that they are valid under applicable law.  If additional permissions

   372 apply only to part of the Program, that part may be used separately

   373 under those permissions, but the entire Program remains governed by

   374 this License without regard to the additional permissions.

   375

   376 When you convey a copy of a covered work, you may at your option

   377 remove any additional permissions from that copy, or from any part of

   378 it.  (Additional permissions may be written to require their own

   379 removal in certain cases when you modify the work.)  You may place

   380 additional permissions on material, added by you to a covered work,

   381 for which you have or can give appropriate copyright permission.

   382

   383 Notwithstanding any other provision of this License, for material you

   384 add to a covered work, you may (if authorized by the copyright holders of

   385 that material) supplement the terms of this License with terms:

   386   \begin{enumerate}

   387   \item Disclaiming warranty or limiting liability differently from the

   388   terms of sections 15 and 16 of this License; or

   389

   390   \item Requiring preservation of specified reasonable legal notices or

   391   author attributions in that material or in the Appropriate Legal

   392   Notices displayed by works containing it; or

   393

   394   \item Prohibiting misrepresentation of the origin of that material, or

   395   requiring that modified versions of such material be marked in

   396   reasonable ways as different from the original version; or

   397

   398   \item Limiting the use for publicity purposes of names of licensors or

   399   authors of the material; or

   400

   401   \item Declining to grant rights under trademark law for use of some

   402   trade names, trademarks, or service marks; or

   403

   404   \item Requiring indemnification of licensors and authors of that

   405   material by anyone who conveys the material (or modified versions of

   406   it) with contractual assumptions of liability to the recipient, for

   407   any liability that these contractual assumptions directly impose on

   408   those licensors and authors.

   409   \end{enumerate}

   410

   411 All other non-permissive additional terms are considered further

   412 restrictions'' within the meaning of section 10.  If the Program as you

   413 received it, or any part of it, contains a notice stating that it is

   414 governed by this License along with a term that is a further

   415 restriction, you may remove that term.  If a license document contains

   416 a further restriction but permits relicensing or conveying under this

   417 License, you may add to a covered work material governed by the terms

   418 of that license document, provided that the further restriction does

   419 not survive such relicensing or conveying.

   420

   421 If you add terms to a covered work in accord with this section, you

   422 must place, in the relevant source files, a statement of the

   423 additional terms that apply to those files, or a notice indicating

   424 where to find the applicable terms.

   425

   426 Additional terms, permissive or non-permissive, may be stated in the

   427 form of a separately written license, or stated as exceptions;

   428 the above requirements apply either way.

   429

   430 \item Termination.

   431

   432 You may not propagate or modify a covered work except as expressly

   433 provided under this License.  Any attempt otherwise to propagate or

   434 modify it is void, and will automatically terminate your rights under

   435 this License (including any patent licenses granted under the third

   436 paragraph of section 11).

   437

   438 However, if you cease all violation of this License, then your

   439 license from a particular copyright holder is reinstated (a)

   440 provisionally, unless and until the copyright holder explicitly and

   441 finally terminates your license, and (b) permanently, if the copyright

   442 holder fails to notify you of the violation by some reasonable means

   443 prior to 60 days after the cessation.

   444

   445 Moreover, your license from a particular copyright holder is

   446 reinstated permanently if the copyright holder notifies you of the

   447 violation by some reasonable means, this is the first time you have

   448 received notice of violation of this License (for any work) from that

   449 copyright holder, and you cure the violation prior to 30 days after

   450 your receipt of the notice.

   451

   452 Termination of your rights under this section does not terminate the

   453 licenses of parties who have received copies or rights from you under

   454 this License.  If your rights have been terminated and not permanently

   455 reinstated, you do not qualify to receive new licenses for the same

   456 material under section 10.

   457

   458 \item Acceptance Not Required for Having Copies.

   459

   460 You are not required to accept this License in order to receive or

   461 run a copy of the Program.  Ancillary propagation of a covered work

   462 occurring solely as a consequence of using peer-to-peer transmission

   463 to receive a copy likewise does not require acceptance.  However,

   464 nothing other than this License grants you permission to propagate or

   465 modify any covered work.  These actions infringe copyright if you do

   466 not accept this License.  Therefore, by modifying or propagating a

   467 covered work, you indicate your acceptance of this License to do so.

   468

   469 \item Automatic Licensing of Downstream Recipients.

   470

   471 Each time you convey a covered work, the recipient automatically

   472 receives a license from the original licensors, to run, modify and

   473 propagate that work, subject to this License.  You are not responsible

   474 for enforcing compliance by third parties with this License.

   475

   476 An entity transaction'' is a transaction transferring control of an

   477 organization, or substantially all assets of one, or subdividing an

   478 organization, or merging organizations.  If propagation of a covered

   479 work results from an entity transaction, each party to that

   480 transaction who receives a copy of the work also receives whatever

   481 licenses to the work the party's predecessor in interest had or could

   482 give under the previous paragraph, plus a right to possession of the

   483 Corresponding Source of the work from the predecessor in interest, if

   484 the predecessor has it or can get it with reasonable efforts.

   485

   486 You may not impose any further restrictions on the exercise of the

   487 rights granted or affirmed under this License.  For example, you may

   488 not impose a license fee, royalty, or other charge for exercise of

   489 rights granted under this License, and you may not initiate litigation

   490 (including a cross-claim or counterclaim in a lawsuit) alleging that

   491 any patent claim is infringed by making, using, selling, offering for

   492 sale, or importing the Program or any portion of it.

   493

   494 \item Patents.

   495

   496 A contributor'' is a copyright holder who authorizes use under this

   497 License of the Program or a work on which the Program is based.  The

   498 work thus licensed is called the contributor's contributor version''.

   499

   500 A contributor's essential patent claims'' are all patent claims

   501 owned or controlled by the contributor, whether already acquired or

   502 hereafter acquired, that would be infringed by some manner, permitted

   503 by this License, of making, using, or selling its contributor version,

   504 but do not include claims that would be infringed only as a

   505 consequence of further modification of the contributor version.  For

   506 purposes of this definition, control'' includes the right to grant

   507 patent sublicenses in a manner consistent with the requirements of

   508 this License.

   509

   510 Each contributor grants you a non-exclusive, worldwide, royalty-free

   511 patent license under the contributor's essential patent claims, to

   512 make, use, sell, offer for sale, import and otherwise run, modify and

   513 propagate the contents of its contributor version.

   514

   515 In the following three paragraphs, a patent license'' is any express

   516 agreement or commitment, however denominated, not to enforce a patent

   517 (such as an express permission to practice a patent or covenant not to

   518 sue for patent infringement).  To grant'' such a patent license to a

   519 party means to make such an agreement or commitment not to enforce a

   520 patent against the party.

   521

   522 If you convey a covered work, knowingly relying on a patent license,

   523 and the Corresponding Source of the work is not available for anyone

   524 to copy, free of charge and under the terms of this License, through a

   525 publicly available network server or other readily accessible means,

   526 then you must either (1) cause the Corresponding Source to be so

   527 available, or (2) arrange to deprive yourself of the benefit of the

   528 patent license for this particular work, or (3) arrange, in a manner

   529 consistent with the requirements of this License, to extend the patent

   530 license to downstream recipients.  Knowingly relying'' means you have

   531 actual knowledge that, but for the patent license, your conveying the

   532 covered work in a country, or your recipient's use of the covered work

   533 in a country, would infringe one or more identifiable patents in that

   534 country that you have reason to believe are valid.

   535

   536 If, pursuant to or in connection with a single transaction or

   537 arrangement, you convey, or propagate by procuring conveyance of, a

   538 covered work, and grant a patent license to some of the parties

   539 receiving the covered work authorizing them to use, propagate, modify

   540 or convey a specific copy of the covered work, then the patent license

   541 you grant is automatically extended to all recipients of the covered

   542 work and works based on it.

   543

   544 A patent license is discriminatory'' if it does not include within

   545 the scope of its coverage, prohibits the exercise of, or is

   546 conditioned on the non-exercise of one or more of the rights that are

   547 specifically granted under this License.  You may not convey a covered

   548 work if you are a party to an arrangement with a third party that is

   549 in the business of distributing software, under which you make payment

   550 to the third party based on the extent of your activity of conveying

   551 the work, and under which the third party grants, to any of the

   552 parties who would receive the covered work from you, a discriminatory

   553 patent license (a) in connection with copies of the covered work

   554 conveyed by you (or copies made from those copies), or (b) primarily

   555 for and in connection with specific products or compilations that

   556 contain the covered work, unless you entered into that arrangement,

   557 or that patent license was granted, prior to 28 March 2007.

   558

   559 Nothing in this License shall be construed as excluding or limiting

   560 any implied license or other defenses to infringement that may

   561 otherwise be available to you under applicable patent law.

   562

   563 \item No Surrender of Others' Freedom.

   564

   565 If conditions are imposed on you (whether by court order, agreement or

   566 otherwise) that contradict the conditions of this License, they do not

   567 excuse you from the conditions of this License.  If you cannot convey a

   568 covered work so as to satisfy simultaneously your obligations under this

   569 License and any other pertinent obligations, then as a consequence you may

   570 not convey it at all.  For example, if you agree to terms that obligate you

   571 to collect a royalty for further conveying from those to whom you convey

   572 the Program, the only way you could satisfy both those terms and this

   573 License would be to refrain entirely from conveying the Program.

   574

   575 \item Use with the GNU Affero General Public License.

   576

   577 Notwithstanding any other provision of this License, you have

   578 permission to link or combine any covered work with a work licensed

   579 under version 3 of the GNU Affero General Public License into a single

   580 combined work, and to convey the resulting work.  The terms of this

   581 License will continue to apply to the part which is the covered work,

   582 but the special requirements of the GNU Affero General Public License,

   583 section 13, concerning interaction through a network will apply to the

   584 combination as such.

   585

   586 \item Revised Versions of this License.

   587

   588 The Free Software Foundation may publish revised and/or new versions of

   589 the GNU General Public License from time to time.  Such new versions will

   590 be similar in spirit to the present version, but may differ in detail to

   591 address new problems or concerns.

   592

   593 Each version is given a distinguishing version number.  If the

   594 Program specifies that a certain numbered version of the GNU General

   595 Public License or any later version'' applies to it, you have the

   596 option of following the terms and conditions either of that numbered

   597 version or of any later version published by the Free Software

   598 Foundation.  If the Program does not specify a version number of the

   599 GNU General Public License, you may choose any version ever published

   600 by the Free Software Foundation.

   601

   602 If the Program specifies that a proxy can decide which future

   603 versions of the GNU General Public License can be used, that proxy's

   604 public statement of acceptance of a version permanently authorizes you

   605 to choose that version for the Program.

   606

   607 Later license versions may give you additional or different

   608 permissions.  However, no additional obligations are imposed on any

   609 author or copyright holder as a result of your choosing to follow a

   610 later version.

   611

   612 \item Disclaimer of Warranty.

   613

   614 \begin{sloppypar}

   615  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY

   616  APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE

   617  COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM AS IS''

   618  WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,

   619  INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF

   620  MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE

   621  RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.

   622  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL

   623  NECESSARY SERVICING, REPAIR OR CORRECTION.

   624 \end{sloppypar}

   625

   626 \item Limitation of Liability.

   627

   628  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN

   629  WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES

   630  AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR

   631  DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL

   632  DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM

   633  (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED

   634  INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE

   635  OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH

   636  HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH

   637  DAMAGES.

   638

   639 \item Interpretation of Sections 15 and 16.

   640

   641 If the disclaimer of warranty and limitation of liability provided

   642 above cannot be given local legal effect according to their terms,

   643 reviewing courts shall apply local law that most closely approximates

   644 an absolute waiver of all civil liability in connection with the

   645 Program, unless a warranty or assumption of liability accompanies a

   646 copy of the Program in return for a fee.

   652 How to Apply These Terms to Your New Programs

   653 \end{center}

   654

   655 If you develop a new program, and you want it to be of the greatest

   656 possible use to the public, the best way to achieve this is to make it

   657 free software which everyone can redistribute and change under these terms.

   658

   659 To do so, attach the following notices to the program.  It is safest

   660 to attach them to the start of each source file to most effectively

   661 state the exclusion of warranty; and each file should have at least

   662 the copyright'' line and a pointer to where the full notice is found.

   663

   664 {\footnotesize

   665 \begin{verbatim}

   666 <one line to give the program's name and a brief idea of what it does.>

   667

   668 Copyright (C) <textyear>  <name of author>

   669

   670 This program is free software: you can redistribute it and/or modify

   671 it under the terms of the GNU General Public License as published by

   672 the Free Software Foundation, either version 3 of the License, or

   673 (at your option) any later version.

   674

   675 This program is distributed in the hope that it will be useful,

   676 but WITHOUT ANY WARRANTY; without even the implied warranty of

   677 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

   678 GNU General Public License for more details.

   679

   680 You should have received a copy of the GNU General Public License

   681 along with this program.  If not, see <http://www.gnu.org/licenses/>.

   682 \end{verbatim}

   683 }

   684

   685 Also add information on how to contact you by electronic and paper mail.

   686

   687 If the program does terminal interaction, make it output a short

   688 notice like this when it starts in an interactive mode:

   689

   690 {\footnotesize

   691 \begin{verbatim}

   692 <program>  Copyright (C) <year>  <name of author>

   693

   694 This program comes with ABSOLUTELY NO WARRANTY; for details type show w'.

   695 This is free software, and you are welcome to redistribute it

   696 under certain conditions; type show c' for details.

   697 \end{verbatim}

   698 }

   699

   700 The hypothetical commands {\tt show w} and {\tt show c} should show

   701 the appropriate

   702 parts of the General Public License.  Of course, your program's commands

   703 might be different; for a GUI interface, you would use an about box''.

   704

   705 You should also get your employer (if you work as a programmer) or

   706 school, if any, to sign a copyright disclaimer'' for the program, if

   707 necessary.  For more information on this, and how to apply and follow

   708 the GNU GPL, see \texttt{http://www.gnu.org/licenses/}.

   709

   710 The GNU General Public License does not permit incorporating your

   711 program into proprietary programs.  If your program is a subroutine

   712 library, you may consider it more useful to permit linking proprietary

   713 applications with the library.  If this is what you want to do, use

   714 the GNU Lesser General Public License instead of this License.  But

   715 first, please read \texttt{http://www.gnu.org/philosophy/why-not-lgpl.html}.
