6 //This source code and any program in which it is compiled/used is provided under the GNU GENERAL
7 //PUBLIC LICENSE, Version 3, full license text below.
8 //-------------------------------------------------------------------------------------------------
10 // Version 3, 29 June 2007
11 //
12 // Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
13 // Everyone is permitted to copy and distribute verbatim copies
14 // of this license document, but changing it is not allowed.
15 //
16 // Preamble
17 //
18 // The GNU General Public License is a free, copyleft license for
19 //software and other kinds of works.
20 //
21 // The licenses for most software and other practical works are designed
22 //to take away your freedom to share and change the works. By contrast,
23 //the GNU General Public License is intended to guarantee your freedom to
24 //share and change all versions of a program--to make sure it remains free
25 //software for all its users. We, the Free Software Foundation, use the
26 //GNU General Public License for most of our software; it applies also to
27 //any other work released this way by its authors. You can apply it to
28 //your programs, too.
29 //
30 // When we speak of free software, we are referring to freedom, not
31 //price. Our General Public Licenses are designed to make sure that you
32 //have the freedom to distribute copies of free software (and charge for
33 //them if you wish), that you receive source code or can get it if you
34 //want it, that you can change the software or use pieces of it in new
35 //free programs, and that you know you can do these things.
36 //
37 // To protect your rights, we need to prevent others from denying you
38 //these rights or asking you to surrender the rights. Therefore, you have
39 //certain responsibilities if you distribute copies of the software, or if
40 //you modify it: responsibilities to respect the freedom of others.
41 //
42 // For example, if you distribute copies of such a program, whether
43 //gratis or for a fee, you must pass on to the recipients the same
44 //freedoms that you received. You must make sure that they, too, receive
45 //or can get the source code. And you must show them these terms so they
46 //know their rights.
47 //
48 // Developers that use the GNU GPL protect your rights with two steps:
49 //(1) assert copyright on the software, and (2) offer you this License
50 //giving you legal permission to copy, distribute and/or modify it.
51 //
52 // For the developers' and authors' protection, the GPL clearly explains
53 //that there is no warranty for this free software. For both users' and
54 //authors' sake, the GPL requires that modified versions be marked as
55 //changed, so that their problems will not be attributed erroneously to
56 //authors of previous versions.
57 //
58 // Some devices are designed to deny users access to install or run
59 //modified versions of the software inside them, although the manufacturer
60 //can do so. This is fundamentally incompatible with the aim of
61 //protecting users' freedom to change the software. The systematic
62 //pattern of such abuse occurs in the area of products for individuals to
63 //use, which is precisely where it is most unacceptable. Therefore, we
64 //have designed this version of the GPL to prohibit the practice for those
65 //products. If such problems arise substantially in other domains, we
66 //stand ready to extend this provision to those domains in future versions
67 //of the GPL, as needed to protect the freedom of users.
68 //
69 // Finally, every program is threatened constantly by software patents.
70 //States should not allow patents to restrict development and use of
71 //software on general-purpose computers, but in those that do, we wish to
72 //avoid the special danger that patents applied to a free program could
73 //make it effectively proprietary. To prevent this, the GPL assures that
74 //patents cannot be used to render the program non-free.
75 //
76 // The precise terms and conditions for copying, distribution and
77 //modification follow.
78 //
80 //
81 // 0. Definitions.
82 //
83 // "This License" refers to version 3 of the GNU General Public License.
84 //
85 // "Copyright" also means copyright-like laws that apply to other kinds of
86 //works, such as semiconductor masks.
87 //
88 // "The Program" refers to any copyrightable work licensed under this
89 //License. Each licensee is addressed as "you". "Licensees" and
90 //"recipients" may be individuals or organizations.
91 //
92 // To "modify" a work means to copy from or adapt all or part of the work
93 //in a fashion requiring copyright permission, other than the making of an
94 //exact copy. The resulting work is called a "modified version" of the
95 //earlier work or a work "based on" the earlier work.
96 //
97 // A "covered work" means either the unmodified Program or a work based
98 //on the Program.
99 //
100 // To "propagate" a work means to do anything with it that, without
101 //permission, would make you directly or secondarily liable for
102 //infringement under applicable copyright law, except executing it on a
103 //computer or modifying a private copy. Propagation includes copying,
104 //distribution (with or without modification), making available to the
105 //public, and in some countries other activities as well.
106 //
107 // To "convey" a work means any kind of propagation that enables other
108 //parties to make or receive copies. Mere interaction with a user through
109 //a computer network, with no transfer of a copy, is not conveying.
110 //
111 // An interactive user interface displays "Appropriate Legal Notices"
112 //to the extent that it includes a convenient and prominently visible
113 //feature that (1) displays an appropriate copyright notice, and (2)
114 //tells the user that there is no warranty for the work (except to the
115 //extent that warranties are provided), that licensees may convey the
116 //work under this License, and how to view a copy of this License. If
117 //the interface presents a list of user commands or options, such as a
118 //menu, a prominent item in the list meets this criterion.
119 //
120 // 1. Source Code.
121 //
122 // The "source code" for a work means the preferred form of the work
123 //for making modifications to it. "Object code" means any non-source
124 //form of a work.
125 //
126 // A "Standard Interface" means an interface that either is an official
127 //standard defined by a recognized standards body, or, in the case of
128 //interfaces specified for a particular programming language, one that
129 //is widely used among developers working in that language.
130 //
131 // The "System Libraries" of an executable work include anything, other
132 //than the work as a whole, that (a) is included in the normal form of
133 //packaging a Major Component, but which is not part of that Major
134 //Component, and (b) serves only to enable use of the work with that
135 //Major Component, or to implement a Standard Interface for which an
136 //implementation is available to the public in source code form. A
137 //"Major Component", in this context, means a major essential component
138 //(kernel, window system, and so on) of the specific operating system
139 //(if any) on which the executable work runs, or a compiler used to
140 //produce the work, or an object code interpreter used to run it.
141 //
142 // The "Corresponding Source" for a work in object code form means all
143 //the source code needed to generate, install, and (for an executable
144 //work) run the object code and to modify the work, including scripts to
145 //control those activities. However, it does not include the work's
146 //System Libraries, or general-purpose tools or generally available free
147 //programs which are used unmodified in performing those activities but
148 //which are not part of the work. For example, Corresponding Source
149 //includes interface definition files associated with source files for
150 //the work, and the source code for shared libraries and dynamically
151 //linked subprograms that the work is specifically designed to require,
152 //such as by intimate data communication or control flow between those
153 //subprograms and other parts of the work.
154 //
155 // The Corresponding Source need not include anything that users
156 //can regenerate automatically from other parts of the Corresponding
157 //Source.
158 //
159 // The Corresponding Source for a work in source code form is that
160 //same work.
161 //
162 // 2. Basic Permissions.
163 //
164 // All rights granted under this License are granted for the term of
165 //copyright on the Program, and are irrevocable provided the stated
166 //conditions are met. This License explicitly affirms your unlimited
167 //permission to run the unmodified Program. The output from running a
168 //covered work is covered by this License only if the output, given its
169 //content, constitutes a covered work. This License acknowledges your
170 //rights of fair use or other equivalent, as provided by copyright law.
171 //
172 // You may make, run and propagate covered works that you do not
173 //convey, without conditions so long as your license otherwise remains
174 //in force. You may convey covered works to others for the sole purpose
175 //of having them make modifications exclusively for you, or provide you
176 //with facilities for running those works, provided that you comply with
177 //the terms of this License in conveying all material for which you do
178 //not control copyright. Those thus making or running the covered works
179 //for you must do so exclusively on your behalf, under your direction
180 //and control, on terms that prohibit them from making any copies of
181 //your copyrighted material outside their relationship with you.
182 //
183 // Conveying under any other circumstances is permitted solely under
184 //the conditions stated below. Sublicensing is not allowed; section 10
185 //makes it unnecessary.
186 //
187 // 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
188 //
189 // No covered work shall be deemed part of an effective technological
190 //measure under any applicable law fulfilling obligations under article
191 //11 of the WIPO copyright treaty adopted on 20 December 1996, or
192 //similar laws prohibiting or restricting circumvention of such
193 //measures.
194 //
195 // When you convey a covered work, you waive any legal power to forbid
196 //circumvention of technological measures to the extent such circumvention
197 //is effected by exercising rights under this License with respect to
198 //the covered work, and you disclaim any intention to limit operation or
199 //modification of the work as a means of enforcing, against the work's
200 //users, your or third parties' legal rights to forbid circumvention of
201 //technological measures.
202 //
203 // 4. Conveying Verbatim Copies.
204 //
205 // You may convey verbatim copies of the Program's source code as you
206 //receive it, in any medium, provided that you conspicuously and
207 //appropriately publish on each copy an appropriate copyright notice;
208 //keep intact all notices stating that this License and any
209 //non-permissive terms added in accord with section 7 apply to the code;
210 //keep intact all notices of the absence of any warranty; and give all
211 //recipients a copy of this License along with the Program.
212 //
213 // You may charge any price or no price for each copy that you convey,
214 //and you may offer support or warranty protection for a fee.
215 //
216 // 5. Conveying Modified Source Versions.
217 //
218 // You may convey a work based on the Program, or the modifications to
219 //produce it from the Program, in the form of source code under the
220 //terms of section 4, provided that you also meet all of these conditions:
221 //
222 // a) The work must carry prominent notices stating that you modified
223 // it, and giving a relevant date.
224 //
225 // b) The work must carry prominent notices stating that it is
226 // released under this License and any conditions added under section
227 // 7. This requirement modifies the requirement in section 4 to
228 // "keep intact all notices".
229 //
230 // c) You must license the entire work, as a whole, under this
231 // License to anyone who comes into possession of a copy. This
232 // License will therefore apply, along with any applicable section 7
233 // additional terms, to the whole of the work, and all its parts,
234 // regardless of how they are packaged. This License gives no
235 // permission to license the work in any other way, but it does not
236 // invalidate such permission if you have separately received it.
237 //
238 // d) If the work has interactive user interfaces, each must display
239 // Appropriate Legal Notices; however, if the Program has interactive
240 // interfaces that do not display Appropriate Legal Notices, your
241 // work need not make them do so.
242 //
243 // A compilation of a covered work with other separate and independent
244 //works, which are not by their nature extensions of the covered work,
245 //and which are not combined with it such as to form a larger program,
246 //in or on a volume of a storage or distribution medium, is called an
247 //"aggregate" if the compilation and its resulting copyright are not
248 //used to limit the access or legal rights of the compilation's users
249 //beyond what the individual works permit. Inclusion of a covered work
250 //in an aggregate does not cause this License to apply to the other
251 //parts of the aggregate.
252 //
253 // 6. Conveying Non-Source Forms.
254 //
255 // You may convey a covered work in object code form under the terms
256 //of sections 4 and 5, provided that you also convey the
257 //machine-readable Corresponding Source under the terms of this License,
258 //in one of these ways:
259 //
260 // a) Convey the object code in, or embodied in, a physical product
261 // (including a physical distribution medium), accompanied by the
262 // Corresponding Source fixed on a durable physical medium
263 // customarily used for software interchange.
264 //
265 // b) Convey the object code in, or embodied in, a physical product
266 // (including a physical distribution medium), accompanied by a
267 // written offer, valid for at least three years and valid for as
268 // long as you offer spare parts or customer support for that product
269 // model, to give anyone who possesses the object code either (1) a
270 // copy of the Corresponding Source for all the software in the
271 // product that is covered by this License, on a durable physical
272 // medium customarily used for software interchange, for a price no
273 // more than your reasonable cost of physically performing this
274 // conveying of source, or (2) access to copy the
275 // Corresponding Source from a network server at no charge.
276 //
277 // c) Convey individual copies of the object code with a copy of the
278 // written offer to provide the Corresponding Source. This
279 // alternative is allowed only occasionally and noncommercially, and
280 // only if you received the object code with such an offer, in accord
281 // with subsection 6b.
282 //
283 // d) Convey the object code by offering access from a designated
284 // place (gratis or for a charge), and offer equivalent access to the
285 // Corresponding Source in the same way through the same place at no
286 // further charge. You need not require recipients to copy the
287 // Corresponding Source along with the object code. If the place to
288 // copy the object code is a network server, the Corresponding Source
289 // may be on a different server (operated by you or a third party)
290 // that supports equivalent copying facilities, provided you maintain
291 // clear directions next to the object code saying where to find the
292 // Corresponding Source. Regardless of what server hosts the
293 // Corresponding Source, you remain obligated to ensure that it is
294 // available for as long as needed to satisfy these requirements.
295 //
296 // e) Convey the object code using peer-to-peer transmission, provided
297 // you inform other peers where the object code and Corresponding
298 // Source of the work are being offered to the general public at no
299 // charge under subsection 6d.
300 //
301 // A separable portion of the object code, whose source code is excluded
302 //from the Corresponding Source as a System Library, need not be
303 //included in conveying the object code work.
304 //
305 // A "User Product" is either (1) a "consumer product", which means any
306 //tangible personal property which is normally used for personal, family,
307 //or household purposes, or (2) anything designed or sold for incorporation
308 //into a dwelling. In determining whether a product is a consumer product,
309 //doubtful cases shall be resolved in favor of coverage. For a particular
310 //product received by a particular user, "normally used" refers to a
311 //typical or common use of that class of product, regardless of the status
312 //of the particular user or of the way in which the particular user
313 //actually uses, or expects or is expected to use, the product. A product
314 //is a consumer product regardless of whether the product has substantial
315 //commercial, industrial or non-consumer uses, unless such uses represent
316 //the only significant mode of use of the product.
317 //
318 // "Installation Information" for a User Product means any methods,
319 //procedures, authorization keys, or other information required to install
320 //and execute modified versions of a covered work in that User Product from
321 //a modified version of its Corresponding Source. The information must
322 //suffice to ensure that the continued functioning of the modified object
323 //code is in no case prevented or interfered with solely because
324 //modification has been made.
325 //
326 // If you convey an object code work under this section in, or with, or
327 //specifically for use in, a User Product, and the conveying occurs as
328 //part of a transaction in which the right of possession and use of the
329 //User Product is transferred to the recipient in perpetuity or for a
330 //fixed term (regardless of how the transaction is characterized), the
331 //Corresponding Source conveyed under this section must be accompanied
332 //by the Installation Information. But this requirement does not apply
333 //if neither you nor any third party retains the ability to install
334 //modified object code on the User Product (for example, the work has
335 //been installed in ROM).
336 //
337 // The requirement to provide Installation Information does not include a
338 //requirement to continue to provide support service, warranty, or updates
339 //for a work that has been modified or installed by the recipient, or for
340 //the User Product in which it has been modified or installed. Access to a
341 //network may be denied when the modification itself materially and
342 //adversely affects the operation of the network or violates the rules and
343 //protocols for communication across the network.
344 //
345 // Corresponding Source conveyed, and Installation Information provided,
346 //in accord with this section must be in a format that is publicly
347 //documented (and with an implementation available to the public in
348 //source code form), and must require no special password or key for
349 //unpacking, reading or copying.
350 //
351 // 7. Additional Terms.
352 //
353 // "Additional permissions" are terms that supplement the terms of this
354 //License by making exceptions from one or more of its conditions.
355 //Additional permissions that are applicable to the entire Program shall
356 //be treated as though they were included in this License, to the extent
357 //that they are valid under applicable law. If additional permissions
358 //apply only to part of the Program, that part may be used separately
359 //under those permissions, but the entire Program remains governed by
360 //this License without regard to the additional permissions.
361 //
362 // When you convey a copy of a covered work, you may at your option
363 //remove any additional permissions from that copy, or from any part of
364 //it. (Additional permissions may be written to require their own
365 //removal in certain cases when you modify the work.) You may place
366 //additional permissions on material, added by you to a covered work,
367 //for which you have or can give appropriate copyright permission.
368 //
369 // Notwithstanding any other provision of this License, for material you
370 //add to a covered work, you may (if authorized by the copyright holders of
371 //that material) supplement the terms of this License with terms:
372 //
373 // a) Disclaiming warranty or limiting liability differently from the
374 // terms of sections 15 and 16 of this License; or
375 //
376 // 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
379 //
380 // 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
383 //
384 // d) Limiting the use for publicity purposes of names of licensors or
385 // authors of the material; or
386 //
387 // e) Declining to grant rights under trademark law for use of some
388 // trade names, trademarks, or service marks; or
389 //
390 // 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.
395 //
396 // All other non-permissive additional terms are considered "further
397 //restrictions" within the meaning of section 10. If the Program as you
398 //received it, or any part of it, contains a notice stating that it is
399 //governed by this License along with a term that is a further
400 //restriction, you may remove that term. If a license document contains
401 //a further restriction but permits relicensing or conveying under this
402 //License, you may add to a covered work material governed by the terms
403 //of that license document, provided that the further restriction does
404 //not survive such relicensing or conveying.
405 //
406 // If you add terms to a covered work in accord with this section, you
407 //must place, in the relevant source files, a statement of the
408 //additional terms that apply to those files, or a notice indicating
409 //where to find the applicable terms.
410 //
411 // Additional terms, permissive or non-permissive, may be stated in the
412 //form of a separately written license, or stated as exceptions;
413 //the above requirements apply either way.
414 //
415 // 8. Termination.
416 //
417 // You may not propagate or modify a covered work except as expressly
418 //provided under this License. Any attempt otherwise to propagate or
419 //modify it is void, and will automatically terminate your rights under
420 //this License (including any patent licenses granted under the third
421 //paragraph of section 11).
422 //
423 // However, if you cease all violation of this License, then your
424 //license from a particular copyright holder is reinstated (a)
425 //provisionally, unless and until the copyright holder explicitly and
426 //finally terminates your license, and (b) permanently, if the copyright
427 //holder fails to notify you of the violation by some reasonable means
428 //prior to 60 days after the cessation.
429 //
430 // Moreover, your license from a particular copyright holder is
431 //reinstated permanently if the copyright holder notifies you of the
432 //violation by some reasonable means, this is the first time you have
433 //received notice of violation of this License (for any work) from that
434 //copyright holder, and you cure the violation prior to 30 days after
435 //your receipt of the notice.
436 //
437 // Termination of your rights under this section does not terminate the
438 //licenses of parties who have received copies or rights from you under
439 //this License. If your rights have been terminated and not permanently
440 //reinstated, you do not qualify to receive new licenses for the same
441 //material under section 10.
442 //
443 // 9. Acceptance Not Required for Having Copies.
444 //
445 // You are not required to accept this License in order to receive or
446 //run a copy of the Program. Ancillary propagation of a covered work
447 //occurring solely as a consequence of using peer-to-peer transmission
448 //to receive a copy likewise does not require acceptance. However,
449 //nothing other than this License grants you permission to propagate or
450 //modify any covered work. These actions infringe copyright if you do
451 //not accept this License. Therefore, by modifying or propagating a
452 //covered work, you indicate your acceptance of this License to do so.
453 //
454 // 10. Automatic Licensing of Downstream Recipients.
455 //
456 // Each time you convey a covered work, the recipient automatically
457 //receives a license from the original licensors, to run, modify and
458 //propagate that work, subject to this License. You are not responsible
459 //for enforcing compliance by third parties with this License.
460 //
461 // An "entity transaction" is a transaction transferring control of an
462 //organization, or substantially all assets of one, or subdividing an
463 //organization, or merging organizations. If propagation of a covered
464 //work results from an entity transaction, each party to that
465 //transaction who receives a copy of the work also receives whatever
466 //licenses to the work the party's predecessor in interest had or could
467 //give under the previous paragraph, plus a right to possession of the
468 //Corresponding Source of the work from the predecessor in interest, if
469 //the predecessor has it or can get it with reasonable efforts.
470 //
471 // You may not impose any further restrictions on the exercise of the
472 //rights granted or affirmed under this License. For example, you may
473 //not impose a license fee, royalty, or other charge for exercise of
474 //rights granted under this License, and you may not initiate litigation
475 //(including a cross-claim or counterclaim in a lawsuit) alleging that
476 //any patent claim is infringed by making, using, selling, offering for
477 //sale, or importing the Program or any portion of it.
478 //
479 // 11. Patents.
480 //
481 // A "contributor" is a copyright holder who authorizes use under this
482 //License of the Program or a work on which the Program is based. The
483 //work thus licensed is called the contributor's "contributor version".
484 //
485 // A contributor's "essential patent claims" are all patent claims
486 //owned or controlled by the contributor, whether already acquired or
487 //hereafter acquired, that would be infringed by some manner, permitted
488 //by this License, of making, using, or selling its contributor version,
489 //but do not include claims that would be infringed only as a
490 //consequence of further modification of the contributor version. For
491 //purposes of this definition, "control" includes the right to grant
492 //patent sublicenses in a manner consistent with the requirements of
493 //this License.
494 //
495 // Each contributor grants you a non-exclusive, worldwide, royalty-free
496 //patent license under the contributor's essential patent claims, to
497 //make, use, sell, offer for sale, import and otherwise run, modify and
498 //propagate the contents of its contributor version.
499 //
500 // In the following three paragraphs, a "patent license" is any express
501 //agreement or commitment, however denominated, not to enforce a patent
502 //(such as an express permission to practice a patent or covenant not to
503 //sue for patent infringement). To "grant" such a patent license to a
504 //party means to make such an agreement or commitment not to enforce a
505 //patent against the party.
506 //
507 // If you convey a covered work, knowingly relying on a patent license,
508 //and the Corresponding Source of the work is not available for anyone
509 //to copy, free of charge and under the terms of this License, through a
510 //publicly available network server or other readily accessible means,
511 //then you must either (1) cause the Corresponding Source to be so
512 //available, or (2) arrange to deprive yourself of the benefit of the
513 //patent license for this particular work, or (3) arrange, in a manner
514 //consistent with the requirements of this License, to extend the patent
515 //license to downstream recipients. "Knowingly relying" means you have
516 //actual knowledge that, but for the patent license, your conveying the
517 //covered work in a country, or your recipient's use of the covered work
518 //in a country, would infringe one or more identifiable patents in that
519 //country that you have reason to believe are valid.
520 //
521 // If, pursuant to or in connection with a single transaction or
522 //arrangement, you convey, or propagate by procuring conveyance of, a
523 //covered work, and grant a patent license to some of the parties
524 //receiving the covered work authorizing them to use, propagate, modify
525 //or convey a specific copy of the covered work, then the patent license
526 //you grant is automatically extended to all recipients of the covered
527 //work and works based on it.
528 //
529 // A patent license is "discriminatory" if it does not include within
530 //the scope of its coverage, prohibits the exercise of, or is
531 //conditioned on the non-exercise of one or more of the rights that are
532 //specifically granted under this License. You may not convey a covered
533 //work if you are a party to an arrangement with a third party that is
534 //in the business of distributing software, under which you make payment
535 //to the third party based on the extent of your activity of conveying
536 //the work, and under which the third party grants, to any of the
537 //parties who would receive the covered work from you, a discriminatory
538 //patent license (a) in connection with copies of the covered work
539 //conveyed by you (or copies made from those copies), or (b) primarily
540 //for and in connection with specific products or compilations that
541 //contain the covered work, unless you entered into that arrangement,
542 //or that patent license was granted, prior to 28 March 2007.
543 //
544 // Nothing in this License shall be construed as excluding or limiting
545 //any implied license or other defenses to infringement that may
546 //otherwise be available to you under applicable patent law.
547 //
548 // 12. No Surrender of Others' Freedom.
549 //
550 // If conditions are imposed on you (whether by court order, agreement or
551 //otherwise) that contradict the conditions of this License, they do not
552 //excuse you from the conditions of this License. If you cannot convey a
553 //covered work so as to satisfy simultaneously your obligations under this
554 //License and any other pertinent obligations, then as a consequence you may
555 //not convey it at all. For example, if you agree to terms that obligate you
556 //to collect a royalty for further conveying from those to whom you convey
557 //the Program, the only way you could satisfy both those terms and this
558 //License would be to refrain entirely from conveying the Program.
559 //
560 // 13. Use with the GNU Affero General Public License.
561 //
562 // Notwithstanding any other provision of this License, you have
563 //permission to link or combine any covered work with a work licensed
564 //under version 3 of the GNU Affero General Public License into a single
565 //combined work, and to convey the resulting work. The terms of this
566 //License will continue to apply to the part which is the covered work,
567 //but the special requirements of the GNU Affero General Public License,
568 //section 13, concerning interaction through a network will apply to the
569 //combination as such.
570 //
571 // 14. Revised Versions of this License.
572 //
573 // The Free Software Foundation may publish revised and/or new versions of
574 //the GNU General Public License from time to time. Such new versions will
575 //be similar in spirit to the present version, but may differ in detail to
576 //address new problems or concerns.
577 //
578 // Each version is given a distinguishing version number. If the
579 //Program specifies that a certain numbered version of the GNU General
580 //Public License "or any later version" applies to it, you have the
581 //option of following the terms and conditions either of that numbered
582 //version or of any later version published by the Free Software
583 //Foundation. If the Program does not specify a version number of the
584 //GNU General Public License, you may choose any version ever published
585 //by the Free Software Foundation.
586 //
587 // If the Program specifies that a proxy can decide which future
588 //versions of the GNU General Public License can be used, that proxy's
589 //public statement of acceptance of a version permanently authorizes you
590 //to choose that version for the Program.
591 //
592 // Later license versions may give you additional or different
593 //permissions. However, no additional obligations are imposed on any
594 //author or copyright holder as a result of your choosing to follow a
595 //later version.
596 //
597 // 15. Disclaimer of Warranty.
598 //
607 //
608 // 16. Limitation of Liability.
609 //
619 //
620 // 17. Interpretation of Sections 15 and 16.
621 //
622 // If the disclaimer of warranty and limitation of liability provided
623 //above cannot be given local legal effect according to their terms,
624 //reviewing courts shall apply local law that most closely approximates
625 //an absolute waiver of all civil liability in connection with the
626 //Program, unless a warranty or assumption of liability accompanies a
627 //copy of the Program in return for a fee.
628 //
630 //
631 // How to Apply These Terms to Your New Programs
632 //
633 // If you develop a new program, and you want it to be of the greatest
634 //possible use to the public, the best way to achieve this is to make it
635 //free software which everyone can redistribute and change under these terms.
636 //
637 // To do so, attach the following notices to the program. It is safest
638 //to attach them to the start of each source file to most effectively
639 //state the exclusion of warranty; and each file should have at least
640 //the "copyright" line and a pointer to where the full notice is found.
641 //
642 // <one line to give the program's name and a brief idea of what it does.>
643 // Copyright (C) <year> <name of author>
644 //
645 // This program is free software: you can redistribute it and/or modify
646 // it under the terms of the GNU General Public License as published by
647 // the Free Software Foundation, either version 3 of the License, or
648 // (at your option) any later version.
649 //
650 // This program is distributed in the hope that it will be useful,
651 // but WITHOUT ANY WARRANTY; without even the implied warranty of
653 // GNU General Public License for more details.
654 //
655 // You should have received a copy of the GNU General Public License
656 // along with this program. If not, see <http://www.gnu.org/licenses/>.
657 //
658 //Also add information on how to contact you by electronic and paper mail.
659 //
660 // If the program does terminal interaction, make it output a short
661 //notice like this when it starts in an interactive mode:
662 //
663 // <program> Copyright (C) <year> <name of author>
664 // This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
665 // This is free software, and you are welcome to redistribute it
666 // under certain conditions; type `show c' for details.
667 //
668 //The hypothetical commands `show w' and `show c' should show the appropriate
669 //parts of the General Public License. Of course, your program's commands
670 //might be different; for a GUI interface, you would use an "about box".
671 //
672 // You should also get your employer (if you work as a programmer) or school,
673 //if any, to sign a "copyright disclaimer" for the program, if necessary.
674 //For more information on this, and how to apply and follow the GNU GPL, see
675 //<http://www.gnu.org/licenses/>.
676 //
677 // The GNU General Public License does not permit incorporating your program
678 //into proprietary programs. If your program is a subroutine library, you
679 //may consider it more useful to permit linking proprietary applications with
680 //the library. If this is what you want to do, use the GNU Lesser General
681 //Public License instead of this License. But first, please read
682 //<http://www.gnu.org/philosophy/why-not-lgpl.html>.
