29 // Version 3, 29 June 2007
30 //
31 // Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
32 // Everyone is permitted to copy and distribute verbatim copies
33 // of this license document, but changing it is not allowed.
34 //
35 // Preamble
36 //
37 // The GNU General Public License is a free, copyleft license for
38 //software and other kinds of works.
39 //
40 // The licenses for most software and other practical works are designed
41 //to take away your freedom to share and change the works. By contrast,
42 //the GNU General Public License is intended to guarantee your freedom to
43 //share and change all versions of a program--to make sure it remains free
44 //software for all its users. We, the Free Software Foundation, use the
45 //GNU General Public License for most of our software; it applies also to
46 //any other work released this way by its authors. You can apply it to
47 //your programs, too.
48 //
49 // When we speak of free software, we are referring to freedom, not
50 //price. Our General Public Licenses are designed to make sure that you
51 //have the freedom to distribute copies of free software (and charge for
52 //them if you wish), that you receive source code or can get it if you
53 //want it, that you can change the software or use pieces of it in new
54 //free programs, and that you know you can do these things.
55 //
56 // To protect your rights, we need to prevent others from denying you
57 //these rights or asking you to surrender the rights. Therefore, you have
58 //certain responsibilities if you distribute copies of the software, or if
59 //you modify it: responsibilities to respect the freedom of others.
60 //
61 // For example, if you distribute copies of such a program, whether
62 //gratis or for a fee, you must pass on to the recipients the same
63 //freedoms that you received. You must make sure that they, too, receive
64 //or can get the source code. And you must show them these terms so they
65 //know their rights.
66 //
67 // Developers that use the GNU GPL protect your rights with two steps:
68 //(1) assert copyright on the software, and (2) offer you this License
69 //giving you legal permission to copy, distribute and/or modify it.
70 //
71 // For the developers' and authors' protection, the GPL clearly explains
72 //that there is no warranty for this free software. For both users' and
73 //authors' sake, the GPL requires that modified versions be marked as
74 //changed, so that their problems will not be attributed erroneously to
75 //authors of previous versions.
76 //
77 // Some devices are designed to deny users access to install or run
78 //modified versions of the software inside them, although the manufacturer
79 //can do so. This is fundamentally incompatible with the aim of
80 //protecting users' freedom to change the software. The systematic
81 //pattern of such abuse occurs in the area of products for individuals to
82 //use, which is precisely where it is most unacceptable. Therefore, we
83 //have designed this version of the GPL to prohibit the practice for those
84 //products. If such problems arise substantially in other domains, we
85 //stand ready to extend this provision to those domains in future versions
86 //of the GPL, as needed to protect the freedom of users.
87 //
88 // Finally, every program is threatened constantly by software patents.
89 //States should not allow patents to restrict development and use of
90 //software on general-purpose computers, but in those that do, we wish to
91 //avoid the special danger that patents applied to a free program could
92 //make it effectively proprietary. To prevent this, the GPL assures that
93 //patents cannot be used to render the program non-free.
94 //
95 // The precise terms and conditions for copying, distribution and
96 //modification follow.
97 //
99 //
100 // 0. Definitions.
101 //
102 // "This License" refers to version 3 of the GNU General Public License.
103 //
104 // "Copyright" also means copyright-like laws that apply to other kinds of
105 //works, such as semiconductor masks.
106 //
107 // "The Program" refers to any copyrightable work licensed under this
108 //License. Each licensee is addressed as "you". "Licensees" and
109 //"recipients" may be individuals or organizations.
110 //
111 // To "modify" a work means to copy from or adapt all or part of the work
112 //in a fashion requiring copyright permission, other than the making of an
113 //exact copy. The resulting work is called a "modified version" of the
114 //earlier work or a work "based on" the earlier work.
115 //
116 // A "covered work" means either the unmodified Program or a work based
117 //on the Program.
118 //
119 // To "propagate" a work means to do anything with it that, without
120 //permission, would make you directly or secondarily liable for
121 //infringement under applicable copyright law, except executing it on a
122 //computer or modifying a private copy. Propagation includes copying,
123 //distribution (with or without modification), making available to the
124 //public, and in some countries other activities as well.
125 //
126 // To "convey" a work means any kind of propagation that enables other
127 //parties to make or receive copies. Mere interaction with a user through
128 //a computer network, with no transfer of a copy, is not conveying.
129 //
130 // An interactive user interface displays "Appropriate Legal Notices"
131 //to the extent that it includes a convenient and prominently visible
132 //feature that (1) displays an appropriate copyright notice, and (2)
133 //tells the user that there is no warranty for the work (except to the
134 //extent that warranties are provided), that licensees may convey the
135 //work under this License, and how to view a copy of this License. If
136 //the interface presents a list of user commands or options, such as a
137 //menu, a prominent item in the list meets this criterion.
138 //
139 // 1. Source Code.
140 //
141 // The "source code" for a work means the preferred form of the work
142 //for making modifications to it. "Object code" means any non-source
143 //form of a work.
144 //
145 // A "Standard Interface" means an interface that either is an official
146 //standard defined by a recognized standards body, or, in the case of
147 //interfaces specified for a particular programming language, one that
148 //is widely used among developers working in that language.
149 //
150 // The "System Libraries" of an executable work include anything, other
151 //than the work as a whole, that (a) is included in the normal form of
152 //packaging a Major Component, but which is not part of that Major
153 //Component, and (b) serves only to enable use of the work with that
154 //Major Component, or to implement a Standard Interface for which an
155 //implementation is available to the public in source code form. A
156 //"Major Component", in this context, means a major essential component
157 //(kernel, window system, and so on) of the specific operating system
158 //(if any) on which the executable work runs, or a compiler used to
159 //produce the work, or an object code interpreter used to run it.
160 //
161 // The "Corresponding Source" for a work in object code form means all
162 //the source code needed to generate, install, and (for an executable
163 //work) run the object code and to modify the work, including scripts to
164 //control those activities. However, it does not include the work's
165 //System Libraries, or general-purpose tools or generally available free
166 //programs which are used unmodified in performing those activities but
167 //which are not part of the work. For example, Corresponding Source
168 //includes interface definition files associated with source files for
169 //the work, and the source code for shared libraries and dynamically
170 //linked subprograms that the work is specifically designed to require,
171 //such as by intimate data communication or control flow between those
172 //subprograms and other parts of the work.
173 //
174 // The Corresponding Source need not include anything that users
175 //can regenerate automatically from other parts of the Corresponding
176 //Source.
177 //
178 // The Corresponding Source for a work in source code form is that
179 //same work.
180 //
181 // 2. Basic Permissions.
182 //
183 // All rights granted under this License are granted for the term of
184 //copyright on the Program, and are irrevocable provided the stated
185 //conditions are met. This License explicitly affirms your unlimited
186 //permission to run the unmodified Program. The output from running a
187 //covered work is covered by this License only if the output, given its
188 //content, constitutes a covered work. This License acknowledges your
189 //rights of fair use or other equivalent, as provided by copyright law.
190 //
191 // You may make, run and propagate covered works that you do not
192 //convey, without conditions so long as your license otherwise remains
193 //in force. You may convey covered works to others for the sole purpose
194 //of having them make modifications exclusively for you, or provide you
195 //with facilities for running those works, provided that you comply with
196 //the terms of this License in conveying all material for which you do
197 //not control copyright. Those thus making or running the covered works
198 //for you must do so exclusively on your behalf, under your direction
199 //and control, on terms that prohibit them from making any copies of
200 //your copyrighted material outside their relationship with you.
201 //
202 // Conveying under any other circumstances is permitted solely under
203 //the conditions stated below. Sublicensing is not allowed; section 10
204 //makes it unnecessary.
205 //
206 // 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
207 //
208 // No covered work shall be deemed part of an effective technological
209 //measure under any applicable law fulfilling obligations under article
210 //11 of the WIPO copyright treaty adopted on 20 December 1996, or
211 //similar laws prohibiting or restricting circumvention of such
212 //measures.
213 //
214 // When you convey a covered work, you waive any legal power to forbid
215 //circumvention of technological measures to the extent such circumvention
216 //is effected by exercising rights under this License with respect to
217 //the covered work, and you disclaim any intention to limit operation or
218 //modification of the work as a means of enforcing, against the work's
219 //users, your or third parties' legal rights to forbid circumvention of
220 //technological measures.
221 //
222 // 4. Conveying Verbatim Copies.
223 //
224 // You may convey verbatim copies of the Program's source code as you
225 //receive it, in any medium, provided that you conspicuously and
226 //appropriately publish on each copy an appropriate copyright notice;
227 //keep intact all notices stating that this License and any
228 //non-permissive terms added in accord with section 7 apply to the code;
229 //keep intact all notices of the absence of any warranty; and give all
230 //recipients a copy of this License along with the Program.
231 //
232 // You may charge any price or no price for each copy that you convey,
233 //and you may offer support or warranty protection for a fee.
234 //
235 // 5. Conveying Modified Source Versions.
236 //
237 // You may convey a work based on the Program, or the modifications to
238 //produce it from the Program, in the form of source code under the
239 //terms of section 4, provided that you also meet all of these conditions:
240 //
241 // a) The work must carry prominent notices stating that you modified
242 // it, and giving a relevant date.
243 //
244 // b) The work must carry prominent notices stating that it is
245 // released under this License and any conditions added under section
246 // 7. This requirement modifies the requirement in section 4 to
247 // "keep intact all notices".
248 //
249 // c) You must license the entire work, as a whole, under this
250 // License to anyone who comes into possession of a copy. This
251 // License will therefore apply, along with any applicable section 7
252 // additional terms, to the whole of the work, and all its parts,
253 // regardless of how they are packaged. This License gives no
254 // permission to license the work in any other way, but it does not
255 // invalidate such permission if you have separately received it.
256 //
257 // d) If the work has interactive user interfaces, each must display
258 // Appropriate Legal Notices; however, if the Program has interactive
259 // interfaces that do not display Appropriate Legal Notices, your
260 // work need not make them do so.
261 //
262 // A compilation of a covered work with other separate and independent
263 //works, which are not by their nature extensions of the covered work,
264 //and which are not combined with it such as to form a larger program,
265 //in or on a volume of a storage or distribution medium, is called an
266 //"aggregate" if the compilation and its resulting copyright are not
267 //used to limit the access or legal rights of the compilation's users
268 //beyond what the individual works permit. Inclusion of a covered work
269 //in an aggregate does not cause this License to apply to the other
270 //parts of the aggregate.
271 //
272 // 6. Conveying Non-Source Forms.
273 //
274 // You may convey a covered work in object code form under the terms
275 //of sections 4 and 5, provided that you also convey the
276 //machine-readable Corresponding Source under the terms of this License,
277 //in one of these ways:
278 //
279 // a) Convey the object code in, or embodied in, a physical product
280 // (including a physical distribution medium), accompanied by the
281 // Corresponding Source fixed on a durable physical medium
282 // customarily used for software interchange.
283 //
284 // b) Convey the object code in, or embodied in, a physical product
285 // (including a physical distribution medium), accompanied by a
286 // written offer, valid for at least three years and valid for as
287 // long as you offer spare parts or customer support for that product
288 // model, to give anyone who possesses the object code either (1) a
289 // copy of the Corresponding Source for all the software in the
290 // product that is covered by this License, on a durable physical
291 // medium customarily used for software interchange, for a price no
292 // more than your reasonable cost of physically performing this
293 // conveying of source, or (2) access to copy the
294 // Corresponding Source from a network server at no charge.
295 //
296 // c) Convey individual copies of the object code with a copy of the
297 // written offer to provide the Corresponding Source. This
298 // alternative is allowed only occasionally and noncommercially, and
299 // only if you received the object code with such an offer, in accord
300 // with subsection 6b.
301 //
302 // d) Convey the object code by offering access from a designated
303 // place (gratis or for a charge), and offer equivalent access to the
304 // Corresponding Source in the same way through the same place at no
305 // further charge. You need not require recipients to copy the
306 // Corresponding Source along with the object code. If the place to
307 // copy the object code is a network server, the Corresponding Source
308 // may be on a different server (operated by you or a third party)
309 // that supports equivalent copying facilities, provided you maintain
310 // clear directions next to the object code saying where to find the
311 // Corresponding Source. Regardless of what server hosts the
312 // Corresponding Source, you remain obligated to ensure that it is
313 // available for as long as needed to satisfy these requirements.
314 //
315 // e) Convey the object code using peer-to-peer transmission, provided
316 // you inform other peers where the object code and Corresponding
317 // Source of the work are being offered to the general public at no
318 // charge under subsection 6d.
319 //
320 // A separable portion of the object code, whose source code is excluded
321 //from the Corresponding Source as a System Library, need not be
322 //included in conveying the object code work.
323 //
324 // A "User Product" is either (1) a "consumer product", which means any
325 //tangible personal property which is normally used for personal, family,
326 //or household purposes, or (2) anything designed or sold for incorporation
327 //into a dwelling. In determining whether a product is a consumer product,
328 //doubtful cases shall be resolved in favor of coverage. For a particular
329 //product received by a particular user, "normally used" refers to a
330 //typical or common use of that class of product, regardless of the status
331 //of the particular user or of the way in which the particular user
332 //actually uses, or expects or is expected to use, the product. A product
333 //is a consumer product regardless of whether the product has substantial
334 //commercial, industrial or non-consumer uses, unless such uses represent
335 //the only significant mode of use of the product.
336 //
337 // "Installation Information" for a User Product means any methods,
338 //procedures, authorization keys, or other information required to install
339 //and execute modified versions of a covered work in that User Product from
340 //a modified version of its Corresponding Source. The information must
341 //suffice to ensure that the continued functioning of the modified object
342 //code is in no case prevented or interfered with solely because
343 //modification has been made.
344 //
345 // If you convey an object code work under this section in, or with, or
346 //specifically for use in, a User Product, and the conveying occurs as
347 //part of a transaction in which the right of possession and use of the
348 //User Product is transferred to the recipient in perpetuity or for a
349 //fixed term (regardless of how the transaction is characterized), the
350 //Corresponding Source conveyed under this section must be accompanied
351 //by the Installation Information. But this requirement does not apply
352 //if neither you nor any third party retains the ability to install
353 //modified object code on the User Product (for example, the work has
354 //been installed in ROM).
355 //
356 // The requirement to provide Installation Information does not include a
357 //requirement to continue to provide support service, warranty, or updates
358 //for a work that has been modified or installed by the recipient, or for
359 //the User Product in which it has been modified or installed. Access to a
360 //network may be denied when the modification itself materially and
361 //adversely affects the operation of the network or violates the rules and
362 //protocols for communication across the network.
363 //
364 // Corresponding Source conveyed, and Installation Information provided,
365 //in accord with this section must be in a format that is publicly
366 //documented (and with an implementation available to the public in
367 //source code form), and must require no special password or key for
368 //unpacking, reading or copying.
369 //
370 // 7. Additional Terms.
371 //
372 // "Additional permissions" are terms that supplement the terms of this
373 //License by making exceptions from one or more of its conditions.
374 //Additional permissions that are applicable to the entire Program shall
375 //be treated as though they were included in this License, to the extent
376 //that they are valid under applicable law. If additional permissions
377 //apply only to part of the Program, that part may be used separately
378 //under those permissions, but the entire Program remains governed by
379 //this License without regard to the additional permissions.
380 //
381 // When you convey a copy of a covered work, you may at your option
382 //remove any additional permissions from that copy, or from any part of
383 //it. (Additional permissions may be written to require their own
384 //removal in certain cases when you modify the work.) You may place
385 //additional permissions on material, added by you to a covered work,
386 //for which you have or can give appropriate copyright permission.
387 //
388 // Notwithstanding any other provision of this License, for material you
389 //add to a covered work, you may (if authorized by the copyright holders of
390 //that material) supplement the terms of this License with terms:
391 //
392 // a) Disclaiming warranty or limiting liability differently from the
393 // terms of sections 15 and 16 of this License; or
394 //
395 // b) Requiring preservation of specified reasonable legal notices or
396 // author attributions in that material or in the Appropriate Legal
397 // Notices displayed by works containing it; or
398 //
399 // c) Prohibiting misrepresentation of the origin of that material, or
400 // requiring that modified versions of such material be marked in
401 // reasonable ways as different from the original version; or
402 //
403 // d) Limiting the use for publicity purposes of names of licensors or
404 // authors of the material; or
405 //
406 // e) Declining to grant rights under trademark law for use of some
407 // trade names, trademarks, or service marks; or
408 //
409 // f) Requiring indemnification of licensors and authors of that
410 // material by anyone who conveys the material (or modified versions of
411 // it) with contractual assumptions of liability to the recipient, for
412 // any liability that these contractual assumptions directly impose on
413 // those licensors and authors.
414 //
415 // All other non-permissive additional terms are considered "further
416 //restrictions" within the meaning of section 10. If the Program as you
417 //received it, or any part of it, contains a notice stating that it is
418 //governed by this License along with a term that is a further
419 //restriction, you may remove that term. If a license document contains
420 //a further restriction but permits relicensing or conveying under this
421 //License, you may add to a covered work material governed by the terms
422 //of that license document, provided that the further restriction does
423 //not survive such relicensing or conveying.
424 //
425 // If you add terms to a covered work in accord with this section, you
426 //must place, in the relevant source files, a statement of the
427 //additional terms that apply to those files, or a notice indicating
428 //where to find the applicable terms.
429 //
430 // Additional terms, permissive or non-permissive, may be stated in the
431 //form of a separately written license, or stated as exceptions;
432 //the above requirements apply either way.
433 //
434 // 8. Termination.
435 //
436 // You may not propagate or modify a covered work except as expressly
437 //provided under this License. Any attempt otherwise to propagate or
438 //modify it is void, and will automatically terminate your rights under
439 //this License (including any patent licenses granted under the third
440 //paragraph of section 11).
441 //
442 // However, if you cease all violation of this License, then your
443 //license from a particular copyright holder is reinstated (a)
444 //provisionally, unless and until the copyright holder explicitly and
445 //finally terminates your license, and (b) permanently, if the copyright
446 //holder fails to notify you of the violation by some reasonable means
447 //prior to 60 days after the cessation.
448 //
449 // Moreover, your license from a particular copyright holder is
450 //reinstated permanently if the copyright holder notifies you of the
451 //violation by some reasonable means, this is the first time you have
452 //received notice of violation of this License (for any work) from that
453 //copyright holder, and you cure the violation prior to 30 days after
454 //your receipt of the notice.
455 //
456 // Termination of your rights under this section does not terminate the
457 //licenses of parties who have received copies or rights from you under
458 //this License. If your rights have been terminated and not permanently
459 //reinstated, you do not qualify to receive new licenses for the same
460 //material under section 10.
461 //
462 // 9. Acceptance Not Required for Having Copies.
463 //
464 // You are not required to accept this License in order to receive or
465 //run a copy of the Program. Ancillary propagation of a covered work
466 //occurring solely as a consequence of using peer-to-peer transmission
467 //to receive a copy likewise does not require acceptance. However,
468 //nothing other than this License grants you permission to propagate or
469 //modify any covered work. These actions infringe copyright if you do
470 //not accept this License. Therefore, by modifying or propagating a
471 //covered work, you indicate your acceptance of this License to do so.
472 //
473 // 10. Automatic Licensing of Downstream Recipients.
474 //
475 // Each time you convey a covered work, the recipient automatically
476 //receives a license from the original licensors, to run, modify and
477 //propagate that work, subject to this License. You are not responsible
478 //for enforcing compliance by third parties with this License.
479 //
480 // An "entity transaction" is a transaction transferring control of an
481 //organization, or substantially all assets of one, or subdividing an
482 //organization, or merging organizations. If propagation of a covered
483 //work results from an entity transaction, each party to that
484 //transaction who receives a copy of the work also receives whatever
485 //licenses to the work the party's predecessor in interest had or could
486 //give under the previous paragraph, plus a right to possession of the
487 //Corresponding Source of the work from the predecessor in interest, if
488 //the predecessor has it or can get it with reasonable efforts.
489 //
490 // You may not impose any further restrictions on the exercise of the
491 //rights granted or affirmed under this License. For example, you may
492 //not impose a license fee, royalty, or other charge for exercise of
493 //rights granted under this License, and you may not initiate litigation
494 //(including a cross-claim or counterclaim in a lawsuit) alleging that
495 //any patent claim is infringed by making, using, selling, offering for
496 //sale, or importing the Program or any portion of it.
497 //
498 // 11. Patents.
499 //
500 // A "contributor" is a copyright holder who authorizes use under this
501 //License of the Program or a work on which the Program is based. The
502 //work thus licensed is called the contributor's "contributor version".
503 //
504 // A contributor's "essential patent claims" are all patent claims
505 //owned or controlled by the contributor, whether already acquired or
506 //hereafter acquired, that would be infringed by some manner, permitted
507 //by this License, of making, using, or selling its contributor version,
508 //but do not include claims that would be infringed only as a
509 //consequence of further modification of the contributor version. For
510 //purposes of this definition, "control" includes the right to grant
511 //patent sublicenses in a manner consistent with the requirements of
512 //this License.
513 //
514 // Each contributor grants you a non-exclusive, worldwide, royalty-free
515 //patent license under the contributor's essential patent claims, to
516 //make, use, sell, offer for sale, import and otherwise run, modify and
517 //propagate the contents of its contributor version.
518 //
519 // In the following three paragraphs, a "patent license" is any express
520 //agreement or commitment, however denominated, not to enforce a patent
521 //(such as an express permission to practice a patent or covenant not to
522 //sue for patent infringement). To "grant" such a patent license to a
523 //party means to make such an agreement or commitment not to enforce a
524 //patent against the party.
525 //
526 // If you convey a covered work, knowingly relying on a patent license,
527 //and the Corresponding Source of the work is not available for anyone
528 //to copy, free of charge and under the terms of this License, through a
529 //publicly available network server or other readily accessible means,
530 //then you must either (1) cause the Corresponding Source to be so
531 //available, or (2) arrange to deprive yourself of the benefit of the
532 //patent license for this particular work, or (3) arrange, in a manner
533 //consistent with the requirements of this License, to extend the patent
534 //license to downstream recipients. "Knowingly relying" means you have
535 //actual knowledge that, but for the patent license, your conveying the
536 //covered work in a country, or your recipient's use of the covered work
537 //in a country, would infringe one or more identifiable patents in that
538 //country that you have reason to believe are valid.
539 //
540 // If, pursuant to or in connection with a single transaction or
541 //arrangement, you convey, or propagate by procuring conveyance of, a
542 //covered work, and grant a patent license to some of the parties
543 //receiving the covered work authorizing them to use, propagate, modify
544 //or convey a specific copy of the covered work, then the patent license
545 //you grant is automatically extended to all recipients of the covered
546 //work and works based on it.
547 //
548 // A patent license is "discriminatory" if it does not include within
549 //the scope of its coverage, prohibits the exercise of, or is
550 //conditioned on the non-exercise of one or more of the rights that are
551 //specifically granted under this License. You may not convey a covered
552 //work if you are a party to an arrangement with a third party that is
553 //in the business of distributing software, under which you make payment
554 //to the third party based on the extent of your activity of conveying
555 //the work, and under which the third party grants, to any of the
556 //parties who would receive the covered work from you, a discriminatory
557 //patent license (a) in connection with copies of the covered work
558 //conveyed by you (or copies made from those copies), or (b) primarily
559 //for and in connection with specific products or compilations that
560 //contain the covered work, unless you entered into that arrangement,
561 //or that patent license was granted, prior to 28 March 2007.
562 //
563 // Nothing in this License shall be construed as excluding or limiting
564 //any implied license or other defenses to infringement that may
565 //otherwise be available to you under applicable patent law.
566 //
567 // 12. No Surrender of Others' Freedom.
568 //
569 // If conditions are imposed on you (whether by court order, agreement or
570 //otherwise) that contradict the conditions of this License, they do not
571 //excuse you from the conditions of this License. If you cannot convey a
572 //covered work so as to satisfy simultaneously your obligations under this
573 //License and any other pertinent obligations, then as a consequence you may
574 //not convey it at all. For example, if you agree to terms that obligate you
575 //to collect a royalty for further conveying from those to whom you convey
576 //the Program, the only way you could satisfy both those terms and this
577 //License would be to refrain entirely from conveying the Program.
578 //
579 // 13. Use with the GNU Affero General Public License.
580 //
581 // Notwithstanding any other provision of this License, you have
582 //permission to link or combine any covered work with a work licensed
583 //under version 3 of the GNU Affero General Public License into a single
584 //combined work, and to convey the resulting work. The terms of this
585 //License will continue to apply to the part which is the covered work,
586 //but the special requirements of the GNU Affero General Public License,
587 //section 13, concerning interaction through a network will apply to the
588 //combination as such.
589 //
590 // 14. Revised Versions of this License.
591 //
592 // The Free Software Foundation may publish revised and/or new versions of
593 //the GNU General Public License from time to time. Such new versions will
594 //be similar in spirit to the present version, but may differ in detail to
595 //address new problems or concerns.
596 //
597 // Each version is given a distinguishing version number. If the
598 //Program specifies that a certain numbered version of the GNU General
599 //Public License "or any later version" applies to it, you have the
600 //option of following the terms and conditions either of that numbered
601 //version or of any later version published by the Free Software
602 //Foundation. If the Program does not specify a version number of the
603 //GNU General Public License, you may choose any version ever published
604 //by the Free Software Foundation.
605 //
606 // If the Program specifies that a proxy can decide which future
607 //versions of the GNU General Public License can be used, that proxy's
608 //public statement of acceptance of a version permanently authorizes you
609 //to choose that version for the Program.
610 //
611 // Later license versions may give you additional or different
612 //permissions. However, no additional obligations are imposed on any
613 //author or copyright holder as a result of your choosing to follow a
614 //later version.
615 //
616 // 15. Disclaimer of Warranty.
617 //
626 //
627 // 16. Limitation of Liability.
628 //
638 //
639 // 17. Interpretation of Sections 15 and 16.
640 //
641 // If the disclaimer of warranty and limitation of liability provided
642 //above cannot be given local legal effect according to their terms,
643 //reviewing courts shall apply local law that most closely approximates
644 //an absolute waiver of all civil liability in connection with the
645 //Program, unless a warranty or assumption of liability accompanies a
646 //copy of the Program in return for a fee.
647 //
649 //
650 // How to Apply These Terms to Your New Programs
651 //
652 // If you develop a new program, and you want it to be of the greatest
653 //possible use to the public, the best way to achieve this is to make it
654 //free software which everyone can redistribute and change under these terms.
655 //
656 // To do so, attach the following notices to the program. It is safest
657 //to attach them to the start of each source file to most effectively
658 //state the exclusion of warranty; and each file should have at least
659 //the "copyright" line and a pointer to where the full notice is found.
660 //
661 // <one line to give the program's name and a brief idea of what it does.>
662 // Copyright (C) <year> <name of author>
663 //
664 // This program is free software: you can redistribute it and/or modify
665 // it under the terms of the GNU General Public License as published by
666 // the Free Software Foundation, either version 3 of the License, or
667 // (at your option) any later version.
668 //
669 // This program is distributed in the hope that it will be useful,
670 // but WITHOUT ANY WARRANTY; without even the implied warranty of
672 // GNU General Public License for more details.
673 //
674 // You should have received a copy of the GNU General Public License
675 // along with this program. If not, see <http://www.gnu.org/licenses/>.
676 //
677 //Also add information on how to contact you by electronic and paper mail.
678 //
679 // If the program does terminal interaction, make it output a short
680 //notice like this when it starts in an interactive mode:
681 //
682 // <program> Copyright (C) <year> <name of author>
683 // This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
684 // This is free software, and you are welcome to redistribute it
685 // under certain conditions; type `show c' for details.
686 //
687 //The hypothetical commands `show w' and `show c' should show the appropriate
688 //parts of the General Public License. Of course, your program's commands
689 //might be different; for a GUI interface, you would use an "about box".
690 //
691 // You should also get your employer (if you work as a programmer) or school,
692 //if any, to sign a "copyright disclaimer" for the program, if necessary.
693 //For more information on this, and how to apply and follow the GNU GPL, see
694 //<http://www.gnu.org/licenses/>.

696 // The GNU General Public License does not permit incorporating your program
697 //into proprietary programs. If your program is a subroutine library, you
698 //may consider it more useful to permit linking proprietary applications with
