2 <h2 style="text-align: center;">GNU GENERAL PUBLIC LICENSE</h2>
3 <p style="text-align: center;">Version 3, 29 June 2007</p>
4
5 <p>Copyright &copy; 2007 Free Software Foundation, Inc.
6 &lt;<a href="http://fsf.org/">http://fsf.org/</a>&gt;</p><p>
7 Everyone is permitted to copy and distribute verbatim copies
8 of this license document, but changing it is not allowed.</p>
9
10 <h3>Preamble</h3>
11
12 <p>The GNU General Public License is a free, copyleft license for
13 software and other kinds of works.</p>
14
15 <p>The licenses for most software and other practical works are designed
16 to take away your freedom to share and change the works. By contrast,
17 the GNU General Public License is intended to guarantee your freedom to
18 share and change all versions of a program--to make sure it remains free
19 software for all its users. We, the Free Software Foundation, use the
20 GNU General Public License for most of our software; it applies also to
21 any other work released this way by its authors. You can apply it to
22 your programs, too.</p>
23
24 <p>When we speak of free software, we are referring to freedom, not
25 price. Our General Public Licenses are designed to make sure that you
26 have the freedom to distribute copies of free software (and charge for
27 them if you wish), that you receive source code or can get it if you
28 want it, that you can change the software or use pieces of it in new
29 free programs, and that you know you can do these things.</p>
30
31 <p>To protect your rights, we need to prevent others from denying you
32 these rights or asking you to surrender the rights. Therefore, you have
33 certain responsibilities if you distribute copies of the software, or if
34 you modify it: responsibilities to respect the freedom of others.</p>
35
36 <p>For example, if you distribute copies of such a program, whether
37 gratis or for a fee, you must pass on to the recipients the same
38 freedoms that you received. You must make sure that they, too, receive
39 or can get the source code. And you must show them these terms so they
40 know their rights.</p>
41
42 <p>Developers that use the GNU GPL protect your rights with two steps:
43 (1) assert copyright on the software, and (2) offer you this License
44 giving you legal permission to copy, distribute and/or modify it.</p>
45
46 <p>For the developers' and authors' protection, the GPL clearly explains
47 that there is no warranty for this free software. For both users' and
48 authors' sake, the GPL requires that modified versions be marked as
49 changed, so that their problems will not be attributed erroneously to
50 authors of previous versions.</p>
51
52 <p>Some devices are designed to deny users access to install or run
53 modified versions of the software inside them, although the manufacturer
54 can do so. This is fundamentally incompatible with the aim of
55 protecting users' freedom to change the software. The systematic
56 pattern of such abuse occurs in the area of products for individuals to
57 use, which is precisely where it is most unacceptable. Therefore, we
58 have designed this version of the GPL to prohibit the practice for those
59 products. If such problems arise substantially in other domains, we
60 stand ready to extend this provision to those domains in future versions
61 of the GPL, as needed to protect the freedom of users.</p>
62
63 <p>Finally, every program is threatened constantly by software patents.
64 States should not allow patents to restrict development and use of
65 software on general-purpose computers, but in those that do, we wish to
66 avoid the special danger that patents applied to a free program could
67 make it effectively proprietary. To prevent this, the GPL assures that
68 patents cannot be used to render the program non-free.</p>
69
70 <p>The precise terms and conditions for copying, distribution and
71 modification follow.</p>
72
73 <h3><a name="terms"></a>TERMS AND CONDITIONS</h3>
74
75 <h4><a name="section0"></a>0. Definitions.</h4>
76
77 <p>&ldquo;This License&rdquo; refers to version 3 of the GNU General Public License.</p>
78
79 <p>&ldquo;Copyright&rdquo; also means copyright-like laws that apply to other kinds of
80 works, such as semiconductor masks.</p>
81
82 <p>&ldquo;The Program&rdquo; refers to any copyrightable work licensed under this
83 License. Each licensee is addressed as &ldquo;you&rdquo;. &ldquo;Licensees&rdquo; and
84 &ldquo;recipients&rdquo; may be individuals or organizations.</p>
85
86 <p>To &ldquo;modify&rdquo; a work means to copy from or adapt all or part of the work
87 in a fashion requiring copyright permission, other than the making of an
88 exact copy. The resulting work is called a &ldquo;modified version&rdquo; of the
89 earlier work or a work &ldquo;based on&rdquo; the earlier work.</p>
90
91 <p>A &ldquo;covered work&rdquo; means either the unmodified Program or a work based
92 on the Program.</p>
93
94 <p>To &ldquo;propagate&rdquo; a work means to do anything with it that, without
95 permission, would make you directly or secondarily liable for
96 infringement under applicable copyright law, except executing it on a
97 computer or modifying a private copy. Propagation includes copying,
98 distribution (with or without modification), making available to the
99 public, and in some countries other activities as well.</p>
100
101 <p>To &ldquo;convey&rdquo; a work means any kind of propagation that enables other
102 parties to make or receive copies. Mere interaction with a user through
103 a computer network, with no transfer of a copy, is not conveying.</p>
104
105 <p>An interactive user interface displays &ldquo;Appropriate Legal Notices&rdquo;
106 to the extent that it includes a convenient and prominently visible
107 feature that (1) displays an appropriate copyright notice, and (2)
108 tells the user that there is no warranty for the work (except to the
109 extent that warranties are provided), that licensees may convey the
110 work under this License, and how to view a copy of this License. If
111 the interface presents a list of user commands or options, such as a
112 menu, a prominent item in the list meets this criterion.</p>
113
114 <h4><a name="section1"></a>1. Source Code.</h4>
115
116 <p>The &ldquo;source code&rdquo; for a work means the preferred form of the work
117 for making modifications to it. &ldquo;Object code&rdquo; means any non-source
118 form of a work.</p>
119
120 <p>A &ldquo;Standard Interface&rdquo; means an interface that either is an official
121 standard defined by a recognized standards body, or, in the case of
122 interfaces specified for a particular programming language, one that
123 is widely used among developers working in that language.</p>
124
125 <p>The &ldquo;System Libraries&rdquo; of an executable work include anything, other
126 than the work as a whole, that (a) is included in the normal form of
127 packaging a Major Component, but which is not part of that Major
128 Component, and (b) serves only to enable use of the work with that
129 Major Component, or to implement a Standard Interface for which an
130 implementation is available to the public in source code form. A
131 &ldquo;Major Component&rdquo;, in this context, means a major essential component
132 (kernel, window system, and so on) of the specific operating system
133 (if any) on which the executable work runs, or a compiler used to
134 produce the work, or an object code interpreter used to run it.</p>
135
136 <p>The &ldquo;Corresponding Source&rdquo; for a work in object code form means all
137 the source code needed to generate, install, and (for an executable
138 work) run the object code and to modify the work, including scripts to
139 control those activities. However, it does not include the work's
140 System Libraries, or general-purpose tools or generally available free
141 programs which are used unmodified in performing those activities but
142 which are not part of the work. For example, Corresponding Source
143 includes interface definition files associated with source files for
144 the work, and the source code for shared libraries and dynamically
145 linked subprograms that the work is specifically designed to require,
146 such as by intimate data communication or control flow between those
147 subprograms and other parts of the work.</p>
148
149 <p>The Corresponding Source need not include anything that users
150 can regenerate automatically from other parts of the Corresponding
151 Source.</p>
152
153 <p>The Corresponding Source for a work in source code form is that
154 same work.</p>
155
156 <h4><a name="section2"></a>2. Basic Permissions.</h4>
157
158 <p>All rights granted under this License are granted for the term of
159 copyright on the Program, and are irrevocable provided the stated
160 conditions are met. This License explicitly affirms your unlimited
161 permission to run the unmodified Program. The output from running a
162 covered work is covered by this License only if the output, given its
163 content, constitutes a covered work. This License acknowledges your
164 rights of fair use or other equivalent, as provided by copyright law.</p>
165
166 <p>You may make, run and propagate covered works that you do not
167 convey, without conditions so long as your license otherwise remains
168 in force. You may convey covered works to others for the sole purpose
169 of having them make modifications exclusively for you, or provide you
170 with facilities for running those works, provided that you comply with
171 the terms of this License in conveying all material for which you do
172 not control copyright. Those thus making or running the covered works
173 for you must do so exclusively on your behalf, under your direction
174 and control, on terms that prohibit them from making any copies of
175 your copyrighted material outside their relationship with you.</p>
176
177 <p>Conveying under any other circumstances is permitted solely under
178 the conditions stated below. Sublicensing is not allowed; section 10
179 makes it unnecessary.</p>
180
181 <h4><a name="section3"></a>3. Protecting Users' Legal Rights From Anti-Circumvention Law.</h4>
182
183 <p>No covered work shall be deemed part of an effective technological
184 measure under any applicable law fulfilling obligations under article
185 11 of the WIPO copyright treaty adopted on 20 December 1996, or
186 similar laws prohibiting or restricting circumvention of such
187 measures.</p>
188
189 <p>When you convey a covered work, you waive any legal power to forbid
190 circumvention of technological measures to the extent such circumvention
191 is effected by exercising rights under this License with respect to
192 the covered work, and you disclaim any intention to limit operation or
193 modification of the work as a means of enforcing, against the work's
194 users, your or third parties' legal rights to forbid circumvention of
195 technological measures.</p>
196
197 <h4><a name="section4"></a>4. Conveying Verbatim Copies.</h4>
198
199 <p>You may convey verbatim copies of the Program's source code as you
200 receive it, in any medium, provided that you conspicuously and
201 appropriately publish on each copy an appropriate copyright notice;
202 keep intact all notices stating that this License and any
203 non-permissive terms added in accord with section 7 apply to the code;
204 keep intact all notices of the absence of any warranty; and give all
205 recipients a copy of this License along with the Program.</p>
206
207 <p>You may charge any price or no price for each copy that you convey,
208 and you may offer support or warranty protection for a fee.</p>
209
210 <h4><a name="section5"></a>5. Conveying Modified Source Versions.</h4>
211
212 <p>You may convey a work based on the Program, or the modifications to
213 produce it from the Program, in the form of source code under the
214 terms of section 4, provided that you also meet all of these conditions:</p>
215
216 <ul>
217 <li>a) The work must carry prominent notices stating that you modified
218 it, and giving a relevant date.</li>
219
220 <li>b) The work must carry prominent notices stating that it is
221 released under this License and any conditions added under section
222 7. This requirement modifies the requirement in section 4 to
223 &ldquo;keep intact all notices&rdquo;.</li>
224
225 <li>c) You must license the entire work, as a whole, under this
226 License to anyone who comes into possession of a copy. This
227 License will therefore apply, along with any applicable section 7
228 additional terms, to the whole of the work, and all its parts,
229 regardless of how they are packaged. This License gives no
230 permission to license the work in any other way, but it does not
231 invalidate such permission if you have separately received it.</li>
232
233 <li>d) If the work has interactive user interfaces, each must display
234 Appropriate Legal Notices; however, if the Program has interactive
235 interfaces that do not display Appropriate Legal Notices, your
236 work need not make them do so.</li>
237
238 </ul>
239
240 <p>A compilation of a covered work with other separate and independent
241 works, which are not by their nature extensions of the covered work,
242 and which are not combined with it such as to form a larger program,
243 in or on a volume of a storage or distribution medium, is called an
244 &ldquo;aggregate&rdquo; if the compilation and its resulting copyright are not
245 used to limit the access or legal rights of the compilation's users
246 beyond what the individual works permit. Inclusion of a covered work
247 in an aggregate does not cause this License to apply to the other
248 parts of the aggregate.</p>
249
250 <h4><a name="section6"></a>6. Conveying Non-Source Forms.</h4>
251
252 <p>You may convey a covered work in object code form under the terms
253 of sections 4 and 5, provided that you also convey the
254 machine-readable Corresponding Source under the terms of this License,
255 in one of these ways:</p>
256
257 <ul>
258 <li>a) Convey the object code in, or embodied in, a physical product
259 (including a physical distribution medium), accompanied by the
260 Corresponding Source fixed on a durable physical medium
261 customarily used for software interchange.</li>
262
263 <li>b) Convey the object code in, or embodied in, a physical product
264 (including a physical distribution medium), accompanied by a
265 written offer, valid for at least three years and valid for as
266 long as you offer spare parts or customer support for that product
267 model, to give anyone who possesses the object code either (1) a
268 copy of the Corresponding Source for all the software in the
269 product that is covered by this License, on a durable physical
270 medium customarily used for software interchange, for a price no
271 more than your reasonable cost of physically performing this
272 conveying of source, or (2) access to copy the
273 Corresponding Source from a network server at no charge.</li>
274
275 <li>c) Convey individual copies of the object code with a copy of the
276 written offer to provide the Corresponding Source. This
277 alternative is allowed only occasionally and noncommercially, and
278 only if you received the object code with such an offer, in accord
279 with subsection 6b.</li>
280
281 <li>d) Convey the object code by offering access from a designated
282 place (gratis or for a charge), and offer equivalent access to the
283 Corresponding Source in the same way through the same place at no
284 further charge. You need not require recipients to copy the
285 Corresponding Source along with the object code. If the place to
286 copy the object code is a network server, the Corresponding Source
287 may be on a different server (operated by you or a third party)
288 that supports equivalent copying facilities, provided you maintain
289 clear directions next to the object code saying where to find the
290 Corresponding Source. Regardless of what server hosts the
291 Corresponding Source, you remain obligated to ensure that it is
292 available for as long as needed to satisfy these requirements.</li>
293
294 <li>e) Convey the object code using peer-to-peer transmission, provided
295 you inform other peers where the object code and Corresponding
296 Source of the work are being offered to the general public at no
297 charge under subsection 6d.</li>
298 </ul>
299
300 <p>A separable portion of the object code, whose source code is excluded
301 from the Corresponding Source as a System Library, need not be
302 included in conveying the object code work.</p>
303
304 <p>A &ldquo;User Product&rdquo; is either (1) a &ldquo;consumer product&rdquo;, which means any
305 tangible personal property which is normally used for personal, family,
306 or household purposes, or (2) anything designed or sold for incorporation
307 into a dwelling. In determining whether a product is a consumer product,
308 doubtful cases shall be resolved in favor of coverage. For a particular
309 product received by a particular user, &ldquo;normally used&rdquo; refers to a
310 typical or common use of that class of product, regardless of the status
311 of the particular user or of the way in which the particular user
312 actually uses, or expects or is expected to use, the product. A product
313 is a consumer product regardless of whether the product has substantial
314 commercial, industrial or non-consumer uses, unless such uses represent
315 the only significant mode of use of the product.</p>
316
317 <p>&ldquo;Installation Information&rdquo; for a User Product means any methods,
318 procedures, authorization keys, or other information required to install
319 and execute modified versions of a covered work in that User Product from
320 a modified version of its Corresponding Source. The information must
321 suffice to ensure that the continued functioning of the modified object
322 code is in no case prevented or interfered with solely because
323 modification has been made.</p>
324
325 <p>If you convey an object code work under this section in, or with, or
326 specifically for use in, a User Product, and the conveying occurs as
327 part of a transaction in which the right of possession and use of the
328 User Product is transferred to the recipient in perpetuity or for a
329 fixed term (regardless of how the transaction is characterized), the
330 Corresponding Source conveyed under this section must be accompanied
331 by the Installation Information. But this requirement does not apply
332 if neither you nor any third party retains the ability to install
333 modified object code on the User Product (for example, the work has
334 been installed in ROM).</p>
335
336 <p>The requirement to provide Installation Information does not include a
337 requirement to continue to provide support service, warranty, or updates
338 for a work that has been modified or installed by the recipient, or for
339 the User Product in which it has been modified or installed. Access to a
340 network may be denied when the modification itself materially and
341 adversely affects the operation of the network or violates the rules and
342 protocols for communication across the network.</p>
343
344 <p>Corresponding Source conveyed, and Installation Information provided,
345 in accord with this section must be in a format that is publicly
346 documented (and with an implementation available to the public in
347 source code form), and must require no special password or key for
348 unpacking, reading or copying.</p>
349
350 <h4><a name="section7"></a>7. Additional Terms.</h4>
351
352 <p>&ldquo;Additional permissions&rdquo; are terms that supplement the terms of this
353 License by making exceptions from one or more of its conditions.
354 Additional permissions that are applicable to the entire Program shall
355 be treated as though they were included in this License, to the extent
356 that they are valid under applicable law. If additional permissions
357 apply only to part of the Program, that part may be used separately
358 under those permissions, but the entire Program remains governed by
359 this License without regard to the additional permissions.</p>
360
361 <p>When you convey a copy of a covered work, you may at your option
362 remove any additional permissions from that copy, or from any part of
363 it. (Additional permissions may be written to require their own
364 removal in certain cases when you modify the work.) You may place
365 additional permissions on material, added by you to a covered work,
366 for which you have or can give appropriate copyright permission.</p>
367
368 <p>Notwithstanding any other provision of this License, for material you
369 add to a covered work, you may (if authorized by the copyright holders of
370 that material) supplement the terms of this License with terms:</p>
371
372 <ul>
373 <li>a) Disclaiming warranty or limiting liability differently from the
374 terms of sections 15 and 16 of this License; or</li>
375
376 <li>b) Requiring preservation of specified reasonable legal notices or
377 author attributions in that material or in the Appropriate Legal
378 Notices displayed by works containing it; or</li>
379
380 <li>c) Prohibiting misrepresentation of the origin of that material, or
381 requiring that modified versions of such material be marked in
382 reasonable ways as different from the original version; or</li>
383
384 <li>d) Limiting the use for publicity purposes of names of licensors or
385 authors of the material; or</li>
386
387 <li>e) Declining to grant rights under trademark law for use of some
388 trade names, trademarks, or service marks; or</li>
389
390 <li>f) Requiring indemnification of licensors and authors of that
391 material by anyone who conveys the material (or modified versions of
392 it) with contractual assumptions of liability to the recipient, for
393 any liability that these contractual assumptions directly impose on
394 those licensors and authors.</li>
395 </ul>
396
397 <p>All other non-permissive additional terms are considered &ldquo;further
398 restrictions&rdquo; within the meaning of section 10. If the Program as you
399 received it, or any part of it, contains a notice stating that it is
400 governed by this License along with a term that is a further
401 restriction, you may remove that term. If a license document contains
402 a further restriction but permits relicensing or conveying under this
403 License, you may add to a covered work material governed by the terms
404 of that license document, provided that the further restriction does
405 not survive such relicensing or conveying.</p>
406
407 <p>If you add terms to a covered work in accord with this section, you
408 must place, in the relevant source files, a statement of the
409 additional terms that apply to those files, or a notice indicating
410 where to find the applicable terms.</p>
411
412 <p>Additional terms, permissive or non-permissive, may be stated in the
413 form of a separately written license, or stated as exceptions;
414 the above requirements apply either way.</p>
415
416 <h4><a name="section8"></a>8. Termination.</h4>
417
418 <p>You may not propagate or modify a covered work except as expressly
419 provided under this License. Any attempt otherwise to propagate or
420 modify it is void, and will automatically terminate your rights under
421 this License (including any patent licenses granted under the third
422 paragraph of section 11).</p>
423
424 <p>However, if you cease all violation of this License, then your
425 license from a particular copyright holder is reinstated (a)
426 provisionally, unless and until the copyright holder explicitly and
427 finally terminates your license, and (b) permanently, if the copyright
428 holder fails to notify you of the violation by some reasonable means
429 prior to 60 days after the cessation.</p>
430
431 <p>Moreover, your license from a particular copyright holder is
432 reinstated permanently if the copyright holder notifies you of the
433 violation by some reasonable means, this is the first time you have
434 received notice of violation of this License (for any work) from that
435 copyright holder, and you cure the violation prior to 30 days after
436 your receipt of the notice.</p>
437
438 <p>Termination of your rights under this section does not terminate the
439 licenses of parties who have received copies or rights from you under
440 this License. If your rights have been terminated and not permanently
441 reinstated, you do not qualify to receive new licenses for the same
442 material under section 10.</p>
443
444 <h4><a name="section9"></a>9. Acceptance Not Required for Having Copies.</h4>
445
446 <p>You are not required to accept this License in order to receive or
447 run a copy of the Program. Ancillary propagation of a covered work
448 occurring solely as a consequence of using peer-to-peer transmission
449 to receive a copy likewise does not require acceptance. However,
450 nothing other than this License grants you permission to propagate or
451 modify any covered work. These actions infringe copyright if you do
452 not accept this License. Therefore, by modifying or propagating a
453 covered work, you indicate your acceptance of this License to do so.</p>
454
455 <h4><a name="section10"></a>10. Automatic Licensing of Downstream Recipients.</h4>
456
457 <p>Each time you convey a covered work, the recipient automatically
458 receives a license from the original licensors, to run, modify and
459 propagate that work, subject to this License. You are not responsible
460 for enforcing compliance by third parties with this License.</p>
461
462 <p>An &ldquo;entity transaction&rdquo; is a transaction transferring control of an
463 organization, or substantially all assets of one, or subdividing an
464 organization, or merging organizations. If propagation of a covered
465 work results from an entity transaction, each party to that
466 transaction who receives a copy of the work also receives whatever
467 licenses to the work the party's predecessor in interest had or could
468 give under the previous paragraph, plus a right to possession of the
469 Corresponding Source of the work from the predecessor in interest, if
470 the predecessor has it or can get it with reasonable efforts.</p>
471
472 <p>You may not impose any further restrictions on the exercise of the
473 rights granted or affirmed under this License. For example, you may
474 not impose a license fee, royalty, or other charge for exercise of
475 rights granted under this License, and you may not initiate litigation
476 (including a cross-claim or counterclaim in a lawsuit) alleging that
477 any patent claim is infringed by making, using, selling, offering for
478 sale, or importing the Program or any portion of it.</p>

480 <h4><a name="section11"></a>11. Patents.</h4>
481
482 <p>A &ldquo;contributor&rdquo; is a copyright holder who authorizes use under this
483 License of the Program or a work on which the Program is based. The
484 work thus licensed is called the contributor's &ldquo;contributor version&rdquo;.</p>
485
486 <p>A contributor's &ldquo;essential patent claims&rdquo; are all patent claims
487 owned or controlled by the contributor, whether already acquired or
488 hereafter acquired, that would be infringed by some manner, permitted
489 by this License, of making, using, or selling its contributor version,
490 but do not include claims that would be infringed only as a
491 consequence of further modification of the contributor version. For
492 purposes of this definition, &ldquo;control&rdquo; includes the right to grant
493 patent sublicenses in a manner consistent with the requirements of
494 this License.</p>
495
496 <p>Each contributor grants you a non-exclusive, worldwide, royalty-free
497 patent license under the contributor's essential patent claims, to
498 make, use, sell, offer for sale, import and otherwise run, modify and
499 propagate the contents of its contributor version.</p>
500
501 <p>In the following three paragraphs, a &ldquo;patent license&rdquo; is any express
502 agreement or commitment, however denominated, not to enforce a patent
503 (such as an express permission to practice a patent or covenant not to
504 sue for patent infringement). To &ldquo;grant&rdquo; such a patent license to a
505 party means to make such an agreement or commitment not to enforce a
506 patent against the party.</p>
507
508 <p>If you convey a covered work, knowingly relying on a patent license,
509 and the Corresponding Source of the work is not available for anyone
510 to copy, free of charge and under the terms of this License, through a
511 publicly available network server or other readily accessible means,
512 then you must either (1) cause the Corresponding Source to be so
513 available, or (2) arrange to deprive yourself of the benefit of the
514 patent license for this particular work, or (3) arrange, in a manner
515 consistent with the requirements of this License, to extend the patent
516 license to downstream recipients. &ldquo;Knowingly relying&rdquo; means you have
517 actual knowledge that, but for the patent license, your conveying the
518 covered work in a country, or your recipient's use of the covered work
519 in a country, would infringe one or more identifiable patents in that
520 country that you have reason to believe are valid.</p>
521
522
523 <p>If, pursuant to or in connection with a single transaction or
524 arrangement, you convey, or propagate by procuring conveyance of, a
525 covered work, and grant a patent license to some of the parties
526 receiving the covered work authorizing them to use, propagate, modify
527 or convey a specific copy of the covered work, then the patent license
528 you grant is automatically extended to all recipients of the covered
529 work and works based on it.</p>
530
531 <p>A patent license is &ldquo;discriminatory&rdquo; if it does not include within
532 the scope of its coverage, prohibits the exercise of, or is
533 conditioned on the non-exercise of one or more of the rights that are
534 specifically granted under this License. You may not convey a covered
535 work if you are a party to an arrangement with a third party that is
536 in the business of distributing software, under which you make payment
537 to the third party based on the extent of your activity of conveying
538 the work, and under which the third party grants, to any of the
539 parties who would receive the covered work from you, a discriminatory
540 patent license (a) in connection with copies of the covered work
541 conveyed by you (or copies made from those copies), or (b) primarily
542 for and in connection with specific products or compilations that
543 contain the covered work, unless you entered into that arrangement,
544 or that patent license was granted, prior to 28 March 2007.</p>
545
546 <p>Nothing in this License shall be construed as excluding or limiting
547 any implied license or other defenses to infringement that may
548 otherwise be available to you under applicable patent law.</p>
549
550 <h4><a name="section12"></a>12. No Surrender of Others' Freedom.</h4>
551
552 <p>If conditions are imposed on you (whether by court order, agreement or
553 otherwise) that contradict the conditions of this License, they do not
554 excuse you from the conditions of this License. If you cannot convey a
555 covered work so as to satisfy simultaneously your obligations under this
556 License and any other pertinent obligations, then as a consequence you may
557 not convey it at all. For example, if you agree to terms that obligate you
558 to collect a royalty for further conveying from those to whom you convey
559 the Program, the only way you could satisfy both those terms and this
560 License would be to refrain entirely from conveying the Program.</p>
561
562 <h4><a name="section13"></a>13. Use with the GNU Affero General Public License.</h4>
563
564 <p>Notwithstanding any other provision of this License, you have
565 permission to link or combine any covered work with a work licensed
566 under version 3 of the GNU Affero General Public License into a single
567 combined work, and to convey the resulting work. The terms of this
568 License will continue to apply to the part which is the covered work,
569 but the special requirements of the GNU Affero General Public License,
570 section 13, concerning interaction through a network will apply to the
571 combination as such.</p>
572
573 <h4><a name="section14"></a>14. Revised Versions of this License.</h4>
574
575 <p>The Free Software Foundation may publish revised and/or new versions of
576 the GNU General Public License from time to time. Such new versions will
577 be similar in spirit to the present version, but may differ in detail to
578 address new problems or concerns.</p>
579
580 <p>Each version is given a distinguishing version number. If the
581 Program specifies that a certain numbered version of the GNU General
582 Public License &ldquo;or any later version&rdquo; applies to it, you have the
583 option of following the terms and conditions either of that numbered
584 version or of any later version published by the Free Software
585 Foundation. If the Program does not specify a version number of the
586 GNU General Public License, you may choose any version ever published
587 by the Free Software Foundation.</p>
588
589 <p>If the Program specifies that a proxy can decide which future
590 versions of the GNU General Public License can be used, that proxy's
591 public statement of acceptance of a version permanently authorizes you
592 to choose that version for the Program.</p>
593
594 <p>Later license versions may give you additional or different
595 permissions. However, no additional obligations are imposed on any
596 author or copyright holder as a result of your choosing to follow a
597 later version.</p>
598
599 <h4><a name="section15"></a>15. Disclaimer of Warranty.</h4>
600
601 <p>THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
602 APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
603 HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM &ldquo;AS IS&rdquo; WITHOUT WARRANTY
604 OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
605 THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
606 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
607 IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
608 ALL NECESSARY SERVICING, REPAIR OR CORRECTION.</p>
609
610 <h4><a name="section16"></a>16. Limitation of Liability.</h4>
611
612 <p>IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
613 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
614 THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
615 GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
616 USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
617 DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
618 PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
619 EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
620 SUCH DAMAGES.</p>
621
622 <h4><a name="section17"></a>17. Interpretation of Sections 15 and 16.</h4>
623
624 <p>If the disclaimer of warranty and limitation of liability provided
625 above cannot be given local legal effect according to their terms,
626 reviewing courts shall apply local law that most closely approximates
627 an absolute waiver of all civil liability in connection with the
628 Program, unless a warranty or assumption of liability accompanies a
629 copy of the Program in return for a fee.</p>

633 <h3><a name="howto"></a>How to Apply These Terms to Your New Programs</h3>
634
635 <p>If you develop a new program, and you want it to be of the greatest
636 possible use to the public, the best way to achieve this is to make it
637 free software which everyone can redistribute and change under these terms.</p>
638
639 <p>To do so, attach the following notices to the program. It is safest
640 to attach them to the start of each source file to most effectively
641 state the exclusion of warranty; and each file should have at least
642 the &ldquo;copyright&rdquo; line and a pointer to where the full notice is found.</p>
643
644 <pre> &lt;one line to give the program's name and a brief idea of what it does.&gt;
645 Copyright (C) &lt;year&gt; &lt;name of author&gt;
646
647 This program is free software: you can redistribute it and/or modify
648 it under the terms of the GNU General Public License as published by
649 the Free Software Foundation, either version 3 of the License, or
650 (at your option) any later version.
651
652 This program is distributed in the hope that it will be useful,
653 but WITHOUT ANY WARRANTY; without even the implied warranty of
654 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
655 GNU General Public License for more details.
656
657 You should have received a copy of the GNU General Public License
658 along with this program. If not, see &lt;http://www.gnu.org/licenses/&gt;.
659 </pre>
660
661 <p>Also add information on how to contact you by electronic and paper mail.</p>
662
663 <p>If the program does terminal interaction, make it output a short
664 notice like this when it starts in an interactive mode:</p>
665
666 <pre> &lt;program&gt; Copyright (C) &lt;year&gt; &lt;name of author&gt;
667
668 This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
669 This is free software, and you are welcome to redistribute it
670 under certain conditions; type `show c' for details.
671 </pre>
672
673 <p>The hypothetical commands `show w' and `show c' should show the appropriate
674 parts of the General Public License. Of course, your program's commands
675 might be different; for a GUI interface, you would use an &ldquo;about box&rdquo;.</p>
676
677 <p>You should also get your employer (if you work as a programmer) or school,
678 if any, to sign a &ldquo;copyright disclaimer&rdquo; for the program, if necessary.

681
682 <p>The GNU General Public License does not permit incorporating your program
683 into proprietary programs. If your program is a subroutine library, you
684 may consider it more useful to permit linking proprietary applications with
685 the library. If this is what you want to do, use the GNU Lesser General
686 Public License instead of this License. But first, please read
