9 <p style="text-align: center;">Version 3, 29 June 2007</p>
11 <p>Copyright © 2007 Free Software Foundation, Inc.
12 &lt;<a href="http://fsf.org/">http://fsf.org/</a>&gt;</p><p>
13 Everyone is permitted to copy and distribute verbatim copies
14 of this license document, but changing it is not allowed.</p>
16 <h3><a name="preamble"></a>Preamble</h3>
18 <p>The GNU General Public License is a free, copyleft license for
19 software and other kinds of works.</p>
21 <p>The licenses for most software and other practical works are designed
22 to take away your freedom to share and change the works. By contrast,
23 the GNU General Public License is intended to guarantee your freedom to
24 share and change all versions of a program--to make sure it remains free
25 software for all its users. We, the Free Software Foundation, use the
26 GNU General Public License for most of our software; it applies also to
27 any other work released this way by its authors. You can apply it to
28 your programs, too.</p>
30 <p>When we speak of free software, we are referring to freedom, not
31 price. Our General Public Licenses are designed to make sure that you
32 have the freedom to distribute copies of free software (and charge for
33 them if you wish), that you receive source code or can get it if you
34 want it, that you can change the software or use pieces of it in new
35 free programs, and that you know you can do these things.</p>
37 <p>To protect your rights, we need to prevent others from denying you
38 these rights or asking you to surrender the rights. Therefore, you have
39 certain responsibilities if you distribute copies of the software, or if
40 you modify it: responsibilities to respect the freedom of others.</p>
42 <p>For example, if you distribute copies of such a program, whether
43 gratis or for a fee, you must pass on to the recipients the same
44 freedoms that you received. You must make sure that they, too, receive
45 or can get the source code. And you must show them these terms so they
46 know their rights.</p>
48 <p>Developers that use the GNU GPL protect your rights with two steps:
49 (1) assert copyright on the software, and (2) offer you this License
50 giving you legal permission to copy, distribute and/or modify it.</p>
52 <p>For the developers' and authors' protection, the GPL clearly explains
53 that there is no warranty for this free software. For both users' and
54 authors' sake, the GPL requires that modified versions be marked as
55 changed, so that their problems will not be attributed erroneously to
56 authors of previous versions.</p>
58 <p>Some devices are designed to deny users access to install or run
59 modified versions of the software inside them, although the manufacturer
60 can do so. This is fundamentally incompatible with the aim of
61 protecting users' freedom to change the software. The systematic
62 pattern of such abuse occurs in the area of products for individuals to
63 use, which is precisely where it is most unacceptable. Therefore, we
64 have designed this version of the GPL to prohibit the practice for those
65 products. If such problems arise substantially in other domains, we
66 stand ready to extend this provision to those domains in future versions
67 of the GPL, as needed to protect the freedom of users.</p>
69 <p>Finally, every program is threatened constantly by software patents.
70 States should not allow patents to restrict development and use of
71 software on general-purpose computers, but in those that do, we wish to
72 avoid the special danger that patents applied to a free program could
73 make it effectively proprietary. To prevent this, the GPL assures that
74 patents cannot be used to render the program non-free.</p>
76 <p>The precise terms and conditions for copying, distribution and
77 modification follow.</p>
79 <h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
81 <h4><a name="section0"></a>0. Definitions.</h4>
83 <p>“This License” refers to version 3 of the GNU General Public License.</p>
85 <p>“Copyright” also means copyright-like laws that apply to other kinds of
86 works, such as semiconductor masks.</p>
88 <p>“The Program” refers to any copyrightable work licensed under this
89 License. Each licensee is addressed as “you”. “Licensees” and
90 “recipients” may be individuals or organizations.</p>
92 <p>To “modify” a work means to copy from or adapt all or part of the work
93 in a fashion requiring copyright permission, other than the making of an
94 exact copy. The resulting work is called a “modified version” of the
95 earlier work or a work “based on” the earlier work.</p>
97 <p>A “covered work” means either the unmodified Program or a work based
98 on the Program.</p>
100 <p>To “propagate” a work means to do anything with it that, without
101 permission, would make you directly or secondarily liable for
102 infringement under applicable copyright law, except executing it on a
103 computer or modifying a private copy. Propagation includes copying,
104 distribution (with or without modification), making available to the
105 public, and in some countries other activities as well.</p>
107 <p>To “convey” a work means any kind of propagation that enables other
108 parties to make or receive copies. Mere interaction with a user through
109 a computer network, with no transfer of a copy, is not conveying.</p>
111 <p>An interactive user interface displays “Appropriate Legal Notices”
112 to the extent that it includes a convenient and prominently visible
113 feature that (1) displays an appropriate copyright notice, and (2)
114 tells the user that there is no warranty for the work (except to the
115 extent that warranties are provided), that licensees may convey the
116 work under this License, and how to view a copy of this License. If
117 the interface presents a list of user commands or options, such as a
118 menu, a prominent item in the list meets this criterion.</p>
120 <h4><a name="section1"></a>1. Source Code.</h4>
122 <p>The “source code” for a work means the preferred form of the work
123 for making modifications to it. “Object code” means any non-source
124 form of a work.</p>
126 <p>A “Standard Interface” means an interface that either is an official
127 standard defined by a recognized standards body, or, in the case of
128 interfaces specified for a particular programming language, one that
129 is widely used among developers working in that language.</p>
131 <p>The “System Libraries” of an executable work include anything, other
132 than the work as a whole, that (a) is included in the normal form of
133 packaging a Major Component, but which is not part of that Major
134 Component, and (b) serves only to enable use of the work with that
135 Major Component, or to implement a Standard Interface for which an
136 implementation is available to the public in source code form. A
137 “Major Component”, in this context, means a major essential component
138 (kernel, window system, and so on) of the specific operating system
139 (if any) on which the executable work runs, or a compiler used to
140 produce the work, or an object code interpreter used to run it.</p>
142 <p>The “Corresponding Source” for a work in object code form means all
143 the source code needed to generate, install, and (for an executable
144 work) run the object code and to modify the work, including scripts to
145 control those activities. However, it does not include the work's
146 System Libraries, or general-purpose tools or generally available free
147 programs which are used unmodified in performing those activities but
148 which are not part of the work. For example, Corresponding Source
149 includes interface definition files associated with source files for
150 the work, and the source code for shared libraries and dynamically
151 linked subprograms that the work is specifically designed to require,
152 such as by intimate data communication or control flow between those
153 subprograms and other parts of the work.</p>
155 <p>The Corresponding Source need not include anything that users
156 can regenerate automatically from other parts of the Corresponding
157 Source.</p>
159 <p>The Corresponding Source for a work in source code form is that
160 same work.</p>
162 <h4><a name="section2"></a>2. Basic Permissions.</h4>
164 <p>All rights granted under this License are granted for the term of
165 copyright on the Program, and are irrevocable provided the stated
166 conditions are met. This License explicitly affirms your unlimited
167 permission to run the unmodified Program. The output from running a
168 covered work is covered by this License only if the output, given its
169 content, constitutes a covered work. This License acknowledges your
170 rights of fair use or other equivalent, as provided by copyright law.</p>
172 <p>You may make, run and propagate covered works that you do not
173 convey, without conditions so long as your license otherwise remains
174 in force. You may convey covered works to others for the sole purpose
175 of having them make modifications exclusively for you, or provide you
176 with facilities for running those works, provided that you comply with
177 the terms of this License in conveying all material for which you do
178 not control copyright. Those thus making or running the covered works
179 for you must do so exclusively on your behalf, under your direction
180 and control, on terms that prohibit them from making any copies of
181 your copyrighted material outside their relationship with you.</p>
183 <p>Conveying under any other circumstances is permitted solely under
184 the conditions stated below. Sublicensing is not allowed; section 10
185 makes it unnecessary.</p>
187 <h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
189 <p>No covered work shall be deemed part of an effective technological
190 measure under any applicable law fulfilling obligations under article
191 11 of the WIPO copyright treaty adopted on 20 December 1996, or
192 similar laws prohibiting or restricting circumvention of such
193 measures.</p>
195 <p>When you convey a covered work, you waive any legal power to forbid
196 circumvention of technological measures to the extent such circumvention
197 is effected by exercising rights under this License with respect to
198 the covered work, and you disclaim any intention to limit operation or
199 modification of the work as a means of enforcing, against the work's
200 users, your or third parties' legal rights to forbid circumvention of
201 technological measures.</p>
203 <h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
205 <p>You may convey verbatim copies of the Program's source code as you
206 receive it, in any medium, provided that you conspicuously and
207 appropriately publish on each copy an appropriate copyright notice;
208 keep intact all notices stating that this License and any
209 non-permissive terms added in accord with section 7 apply to the code;
210 keep intact all notices of the absence of any warranty; and give all
211 recipients a copy of this License along with the Program.</p>
213 <p>You may charge any price or no price for each copy that you convey,
214 and you may offer support or warranty protection for a fee.</p>
216 <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
218 <p>You may convey a work based on the Program, or the modifications to
219 produce it from the Program, in the form of source code under the
220 terms of section 4, provided that you also meet all of these conditions:</p>
222 <ul>
223 <li>a) The work must carry prominent notices stating that you modified
224 it, and giving a relevant date.</li>
226 <li>b) The work must carry prominent notices stating that it is
227 released under this License and any conditions added under section
228 7. This requirement modifies the requirement in section 4 to
229 “keep intact all notices”.</li>
231 <li>c) You must license the entire work, as a whole, under this
232 License to anyone who comes into possession of a copy. This
233 License will therefore apply, along with any applicable section 7
234 additional terms, to the whole of the work, and all its parts,
235 regardless of how they are packaged. This License gives no
236 permission to license the work in any other way, but it does not
237 invalidate such permission if you have separately received it.</li>
239 <li>d) If the work has interactive user interfaces, each must display
240 Appropriate Legal Notices; however, if the Program has interactive
241 interfaces that do not display Appropriate Legal Notices, your
242 work need not make them do so.</li>
243 </ul>
245 <p>A compilation of a covered work with other separate and independent
246 works, which are not by their nature extensions of the covered work,
247 and which are not combined with it such as to form a larger program,
248 in or on a volume of a storage or distribution medium, is called an
249 “aggregate” if the compilation and its resulting copyright are not
250 used to limit the access or legal rights of the compilation's users
251 beyond what the individual works permit. Inclusion of a covered work
252 in an aggregate does not cause this License to apply to the other
253 parts of the aggregate.</p>
255 <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
257 <p>You may convey a covered work in object code form under the terms
258 of sections 4 and 5, provided that you also convey the
259 machine-readable Corresponding Source under the terms of this License,
260 in one of these ways:</p>
262 <ul>
263 <li>a) Convey the object code in, or embodied in, a physical product
264 (including a physical distribution medium), accompanied by the
265 Corresponding Source fixed on a durable physical medium
266 customarily used for software interchange.</li>
268 <li>b) Convey the object code in, or embodied in, a physical product
269 (including a physical distribution medium), accompanied by a
270 written offer, valid for at least three years and valid for as
271 long as you offer spare parts or customer support for that product
272 model, to give anyone who possesses the object code either (1) a
273 copy of the Corresponding Source for all the software in the
274 product that is covered by this License, on a durable physical
275 medium customarily used for software interchange, for a price no
276 more than your reasonable cost of physically performing this
277 conveying of source, or (2) access to copy the
278 Corresponding Source from a network server at no charge.</li>
280 <li>c) Convey individual copies of the object code with a copy of the
281 written offer to provide the Corresponding Source. This
282 alternative is allowed only occasionally and noncommercially, and
283 only if you received the object code with such an offer, in accord
284 with subsection 6b.</li>
286 <li>d) Convey the object code by offering access from a designated
287 place (gratis or for a charge), and offer equivalent access to the
288 Corresponding Source in the same way through the same place at no
289 further charge. You need not require recipients to copy the
290 Corresponding Source along with the object code. If the place to
291 copy the object code is a network server, the Corresponding Source
292 may be on a different server (operated by you or a third party)
293 that supports equivalent copying facilities, provided you maintain
294 clear directions next to the object code saying where to find the
295 Corresponding Source. Regardless of what server hosts the
296 Corresponding Source, you remain obligated to ensure that it is
297 available for as long as needed to satisfy these requirements.</li>
299 <li>e) Convey the object code using peer-to-peer transmission, provided
300 you inform other peers where the object code and Corresponding
301 Source of the work are being offered to the general public at no
302 charge under subsection 6d.</li>
303 </ul>
305 <p>A separable portion of the object code, whose source code is excluded
306 from the Corresponding Source as a System Library, need not be
307 included in conveying the object code work.</p>
309 <p>A “User Product” is either (1) a “consumer product”, which means any
310 tangible personal property which is normally used for personal, family,
311 or household purposes, or (2) anything designed or sold for incorporation
312 into a dwelling. In determining whether a product is a consumer product,
313 doubtful cases shall be resolved in favor of coverage. For a particular
314 product received by a particular user, “normally used” refers to a
315 typical or common use of that class of product, regardless of the status
316 of the particular user or of the way in which the particular user
317 actually uses, or expects or is expected to use, the product. A product
318 is a consumer product regardless of whether the product has substantial
319 commercial, industrial or non-consumer uses, unless such uses represent
320 the only significant mode of use of the product.</p>
322 <p>“Installation Information” for a User Product means any methods,
323 procedures, authorization keys, or other information required to install
324 and execute modified versions of a covered work in that User Product from
325 a modified version of its Corresponding Source. The information must
326 suffice to ensure that the continued functioning of the modified object
327 code is in no case prevented or interfered with solely because
328 modification has been made.</p>
330 <p>If you convey an object code work under this section in, or with, or
331 specifically for use in, a User Product, and the conveying occurs as
332 part of a transaction in which the right of possession and use of the
333 User Product is transferred to the recipient in perpetuity or for a
334 fixed term (regardless of how the transaction is characterized), the
335 Corresponding Source conveyed under this section must be accompanied
336 by the Installation Information. But this requirement does not apply
337 if neither you nor any third party retains the ability to install
338 modified object code on the User Product (for example, the work has
339 been installed in ROM).</p>
341 <p>The requirement to provide Installation Information does not include a
342 requirement to continue to provide support service, warranty, or updates
343 for a work that has been modified or installed by the recipient, or for
344 the User Product in which it has been modified or installed. Access to a
345 network may be denied when the modification itself materially and
346 adversely affects the operation of the network or violates the rules and
347 protocols for communication across the network.</p>
349 <p>Corresponding Source conveyed, and Installation Information provided,
350 in accord with this section must be in a format that is publicly
351 documented (and with an implementation available to the public in
352 source code form), and must require no special password or key for
353 unpacking, reading or copying.</p>
355 <h4><a name="section7"></a>7. Additional Terms.</h4>
357 <p>“Additional permissions” are terms that supplement the terms of this
358 License by making exceptions from one or more of its conditions.
359 Additional permissions that are applicable to the entire Program shall
360 be treated as though they were included in this License, to the extent
361 that they are valid under applicable law. If additional permissions
362 apply only to part of the Program, that part may be used separately
363 under those permissions, but the entire Program remains governed by
364 this License without regard to the additional permissions.</p>
366 <p>When you convey a copy of a covered work, you may at your option
367 remove any additional permissions from that copy, or from any part of
368 it. (Additional permissions may be written to require their own
369 removal in certain cases when you modify the work.) You may place
370 additional permissions on material, added by you to a covered work,
371 for which you have or can give appropriate copyright permission.</p>
373 <p>Notwithstanding any other provision of this License, for material you
374 add to a covered work, you may (if authorized by the copyright holders of
375 that material) supplement the terms of this License with terms:</p>
377 <ul>
378 <li>a) Disclaiming warranty or limiting liability differently from the
379 terms of sections 15 and 16 of this License; or</li>
381 <li>b) Requiring preservation of specified reasonable legal notices or
382 author attributions in that material or in the Appropriate Legal
383 Notices displayed by works containing it; or</li>
385 <li>c) Prohibiting misrepresentation of the origin of that material, or
386 requiring that modified versions of such material be marked in
387 reasonable ways as different from the original version; or</li>
389 <li>d) Limiting the use for publicity purposes of names of licensors or
390 authors of the material; or</li>
392 <li>e) Declining to grant rights under trademark law for use of some
393 trade names, trademarks, or service marks; or</li>
395 <li>f) Requiring indemnification of licensors and authors of that
396 material by anyone who conveys the material (or modified versions of
397 it) with contractual assumptions of liability to the recipient, for
398 any liability that these contractual assumptions directly impose on
399 those licensors and authors.</li>
400 </ul>
402 <p>All other non-permissive additional terms are considered “further
403 restrictions” within the meaning of section 10. If the Program as you
404 received it, or any part of it, contains a notice stating that it is
405 governed by this License along with a term that is a further
406 restriction, you may remove that term. If a license document contains
407 a further restriction but permits relicensing or conveying under this
408 License, you may add to a covered work material governed by the terms
409 of that license document, provided that the further restriction does
410 not survive such relicensing or conveying.</p>
412 <p>If you add terms to a covered work in accord with this section, you
413 must place, in the relevant source files, a statement of the
414 additional terms that apply to those files, or a notice indicating
415 where to find the applicable terms.</p>
417 <p>Additional terms, permissive or non-permissive, may be stated in the
418 form of a separately written license, or stated as exceptions;
419 the above requirements apply either way.</p>
421 <h4><a name="section8"></a>8. Termination.</h4>
423 <p>You may not propagate or modify a covered work except as expressly
424 provided under this License. Any attempt otherwise to propagate or
425 modify it is void, and will automatically terminate your rights under
426 this License (including any patent licenses granted under the third
427 paragraph of section 11).</p>
429 <p>However, if you cease all violation of this License, then your
430 license from a particular copyright holder is reinstated (a)
431 provisionally, unless and until the copyright holder explicitly and
432 finally terminates your license, and (b) permanently, if the copyright
433 holder fails to notify you of the violation by some reasonable means
434 prior to 60 days after the cessation.</p>
436 <p>Moreover, your license from a particular copyright holder is
437 reinstated permanently if the copyright holder notifies you of the
438 violation by some reasonable means, this is the first time you have
439 received notice of violation of this License (for any work) from that
440 copyright holder, and you cure the violation prior to 30 days after
441 your receipt of the notice.</p>
443 <p>Termination of your rights under this section does not terminate the
444 licenses of parties who have received copies or rights from you under
445 this License. If your rights have been terminated and not permanently
446 reinstated, you do not qualify to receive new licenses for the same
447 material under section 10.</p>
449 <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
451 <p>You are not required to accept this License in order to receive or
452 run a copy of the Program. Ancillary propagation of a covered work
453 occurring solely as a consequence of using peer-to-peer transmission
454 to receive a copy likewise does not require acceptance. However,
455 nothing other than this License grants you permission to propagate or
456 modify any covered work. These actions infringe copyright if you do
457 not accept this License. Therefore, by modifying or propagating a
458 covered work, you indicate your acceptance of this License to do so.</p>
460 <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
462 <p>Each time you convey a covered work, the recipient automatically
463 receives a license from the original licensors, to run, modify and
464 propagate that work, subject to this License. You are not responsible
465 for enforcing compliance by third parties with this License.</p>
467 <p>An “entity transaction” is a transaction transferring control of an
468 organization, or substantially all assets of one, or subdividing an
469 organization, or merging organizations. If propagation of a covered
470 work results from an entity transaction, each party to that
471 transaction who receives a copy of the work also receives whatever
472 licenses to the work the party's predecessor in interest had or could
473 give under the previous paragraph, plus a right to possession of the
474 Corresponding Source of the work from the predecessor in interest, if
475 the predecessor has it or can get it with reasonable efforts.</p>
477 <p>You may not impose any further restrictions on the exercise of the
478 rights granted or affirmed under this License. For example, you may
479 not impose a license fee, royalty, or other charge for exercise of
480 rights granted under this License, and you may not initiate litigation
481 (including a cross-claim or counterclaim in a lawsuit) alleging that
482 any patent claim is infringed by making, using, selling, offering for
483 sale, or importing the Program or any portion of it.</p>
485 <h4><a name="section11"></a>11. Patents.</h4>
487 <p>A “contributor” is a copyright holder who authorizes use under this
488 License of the Program or a work on which the Program is based. The
489 work thus licensed is called the contributor's “contributor version”.</p>
491 <p>A contributor's “essential patent claims” are all patent claims
492 owned or controlled by the contributor, whether already acquired or
493 hereafter acquired, that would be infringed by some manner, permitted
494 by this License, of making, using, or selling its contributor version,
495 but do not include claims that would be infringed only as a
496 consequence of further modification of the contributor version. For
497 purposes of this definition, “control” includes the right to grant
498 patent sublicenses in a manner consistent with the requirements of
499 this License.</p>
501 <p>Each contributor grants you a non-exclusive, worldwide, royalty-free
502 patent license under the contributor's essential patent claims, to
503 make, use, sell, offer for sale, import and otherwise run, modify and
504 propagate the contents of its contributor version.</p>
506 <p>In the following three paragraphs, a “patent license” is any express
507 agreement or commitment, however denominated, not to enforce a patent
508 (such as an express permission to practice a patent or covenant not to
509 sue for patent infringement). To “grant” such a patent license to a
510 party means to make such an agreement or commitment not to enforce a
511 patent against the party.</p>
513 <p>If you convey a covered work, knowingly relying on a patent license,
514 and the Corresponding Source of the work is not available for anyone
515 to copy, free of charge and under the terms of this License, through a
516 publicly available network server or other readily accessible means,
517 then you must either (1) cause the Corresponding Source to be so
518 available, or (2) arrange to deprive yourself of the benefit of the
519 patent license for this particular work, or (3) arrange, in a manner
520 consistent with the requirements of this License, to extend the patent
521 license to downstream recipients. “Knowingly relying” means you have
522 actual knowledge that, but for the patent license, your conveying the
523 covered work in a country, or your recipient's use of the covered work
524 in a country, would infringe one or more identifiable patents in that
525 country that you have reason to believe are valid.</p>
527 <p>If, pursuant to or in connection with a single transaction or
528 arrangement, you convey, or propagate by procuring conveyance of, a
529 covered work, and grant a patent license to some of the parties
530 receiving the covered work authorizing them to use, propagate, modify
531 or convey a specific copy of the covered work, then the patent license
532 you grant is automatically extended to all recipients of the covered
533 work and works based on it.</p>
535 <p>A patent license is “discriminatory” if it does not include within
536 the scope of its coverage, prohibits the exercise of, or is
537 conditioned on the non-exercise of one or more of the rights that are
538 specifically granted under this License. You may not convey a covered
539 work if you are a party to an arrangement with a third party that is
540 in the business of distributing software, under which you make payment
541 to the third party based on the extent of your activity of conveying
542 the work, and under which the third party grants, to any of the
543 parties who would receive the covered work from you, a discriminatory
544 patent license (a) in connection with copies of the covered work
545 conveyed by you (or copies made from those copies), or (b) primarily
546 for and in connection with specific products or compilations that
547 contain the covered work, unless you entered into that arrangement,
548 or that patent license was granted, prior to 28 March 2007.</p>
550 <p>Nothing in this License shall be construed as excluding or limiting
551 any implied license or other defenses to infringement that may
552 otherwise be available to you under applicable patent law.</p>
554 <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
556 <p>If conditions are imposed on you (whether by court order, agreement or
557 otherwise) that contradict the conditions of this License, they do not
558 excuse you from the conditions of this License. If you cannot convey a
559 covered work so as to satisfy simultaneously your obligations under this
560 License and any other pertinent obligations, then as a consequence you may
561 not convey it at all. For example, if you agree to terms that obligate you
562 to collect a royalty for further conveying from those to whom you convey
563 the Program, the only way you could satisfy both those terms and this
564 License would be to refrain entirely from conveying the Program.</p>
566 <h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
568 <p>Notwithstanding any other provision of this License, you have
569 permission to link or combine any covered work with a work licensed
570 under version 3 of the GNU Affero General Public License into a single
571 combined work, and to convey the resulting work. The terms of this
572 License will continue to apply to the part which is the covered work,
573 but the special requirements of the GNU Affero General Public License,
574 section 13, concerning interaction through a network will apply to the
575 combination as such.</p>
577 <h4><a name="section14"></a>14. Revised Versions of this License.</h4>
579 <p>The Free Software Foundation may publish revised and/or new versions of
580 the GNU General Public License from time to time. Such new versions will
581 be similar in spirit to the present version, but may differ in detail to
582 address new problems or concerns.</p>
584 <p>Each version is given a distinguishing version number. If the
585 Program specifies that a certain numbered version of the GNU General
586 Public License “or any later version” applies to it, you have the
587 option of following the terms and conditions either of that numbered
588 version or of any later version published by the Free Software
589 Foundation. If the Program does not specify a version number of the
590 GNU General Public License, you may choose any version ever published
591 by the Free Software Foundation.</p>
593 <p>If the Program specifies that a proxy can decide which future
594 versions of the GNU General Public License can be used, that proxy's
595 public statement of acceptance of a version permanently authorizes you
596 to choose that version for the Program.</p>
598 <p>Later license versions may give you additional or different
599 permissions. However, no additional obligations are imposed on any
600 author or copyright holder as a result of your choosing to follow a
601 later version.</p>
603 <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
605 <p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
606 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
607 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY
608 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
609 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
610 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
611 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
612 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
614 <h4><a name="section16"></a>16. Limitation of Liability.</h4>
616 <p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
617 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
618 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
619 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
620 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
621 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
622 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
623 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
624 SUCH DAMAGES.</p>
626 <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
628 <p>If the disclaimer of warranty and limitation of liability provided
629 above cannot be given local legal effect according to their terms,
630 reviewing courts shall apply local law that most closely approximates
631 an absolute waiver of all civil liability in connection with the
632 Program, unless a warranty or assumption of liability accompanies a
633 copy of the Program in return for a fee.</p>
635 <p>END OF TERMS AND CONDITIONS</p>
637 <h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
639 <p>If you develop a new program, and you want it to be of the greatest
640 possible use to the public, the best way to achieve this is to make it
641 free software which everyone can redistribute and change under these terms.</p>
643 <p>To do so, attach the following notices to the program. It is safest
644 to attach them to the start of each source file to most effectively
645 state the exclusion of warranty; and each file should have at least
646 the “copyright” line and a pointer to where the full notice is found.</p>
648 <pre> &lt;one line to give the program's name and a brief idea of what it does.&gt;
649 Copyright (C) &lt;year&gt; &lt;name of author&gt;
651 This program is free software: you can redistribute it and/or modify
652 it under the terms of the GNU General Public License as published by
653 the Free Software Foundation, either version 3 of the License, or
654 (at your option) any later version.
656 This program is distributed in the hope that it will be useful,
657 but WITHOUT ANY WARRANTY; without even the implied warranty of
658 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
659 GNU General Public License for more details.
661 You should have received a copy of the GNU General Public License
662 along with this program. If not, see &lt;http://www.gnu.org/licenses/&gt;.
663 </pre>
665 <p>Also add information on how to contact you by electronic and paper mail.</p>
667 <p>If the program does terminal interaction, make it output a short
668 notice like this when it starts in an interactive mode:</p>
670 <pre> &lt;program&gt; Copyright (C) &lt;year&gt; &lt;name of author&gt;
671 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
672 This is free software, and you are welcome to redistribute it
673 under certain conditions; type `show c' for details.
674 </pre>
676 <p>The hypothetical commands `show w' and `show c' should show the appropriate
677 parts of the General Public License. Of course, your program's commands
678 might be different; for a GUI interface, you would use an “about box”.</p>
680 <p>You should also get your employer (if you work as a programmer) or school,
681 if any, to sign a “copyright disclaimer” for the program, if necessary.

685 <p>The GNU General Public License does not permit incorporating your program
686 into proprietary programs. If your program is a subroutine library, you
687 may consider it more useful to permit linking proprietary applications with
688 the library. If this is what you want to do, use the GNU Lesser General
689 Public License instead of this License. But first, please read
