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

686 You should have received a copy of the GNU General Public License
687 along with this program. If not, see <http://www.gnu.org/licenses/>.
690 <p>Also add information on how to contact you by electronic and paper
693 <p>If the program does terminal interaction, make it output a short
694 notice like this when it starts in an interactive mode:</p>
696 <pre> <program> Copyright (C) <year> <name of author>
697 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
698 This is free software, and you are welcome to redistribute it
699 under certain conditions; type `show c' for details.
702 <p>The hypothetical commands `show w' and `show c' should show the
704 parts of the General Public License. Of course, your program's commands
705 might be different; for a GUI interface, you would use an “about box”.</p>
707 <p>You should also get your employer (if you work as a programmer) or
709 if any, to sign a “copyright disclaimer” for the program, if necessary.

717 may consider it more useful to permit linking proprietary applications

720 Public License instead of this License. But first, please read
