2 //-------------------------------------------------------------------------------------------------
3 //This source code and any program in which it is compiled/used is provided under the GNU GENERAL
4 //PUBLIC LICENSE, Version 3, full license text below.
5 //-------------------------------------------------------------------------------------------------
6 // GNU GENERAL PUBLIC LICENSE
7 // Version 3, 29 June 2007
8 //
9 // Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
10 // Everyone is permitted to copy and distribute verbatim copies
11 // of this license document, but changing it is not allowed.
12 //
13 // Preamble
14 //
15 // The GNU General Public License is a free, copyleft license for
16 //software and other kinds of works.
17 //
18 // The licenses for most software and other practical works are designed
19 //to take away your freedom to share and change the works. By contrast,
20 //the GNU General Public License is intended to guarantee your freedom to
21 //share and change all versions of a program--to make sure it remains free
22 //software for all its users. We, the Free Software Foundation, use the
23 //GNU General Public License for most of our software; it applies also to
24 //any other work released this way by its authors. You can apply it to
25 //your programs, too.
26 //
27 // When we speak of free software, we are referring to freedom, not
28 //price. Our General Public Licenses are designed to make sure that you
29 //have the freedom to distribute copies of free software (and charge for
30 //them if you wish), that you receive source code or can get it if you
31 //want it, that you can change the software or use pieces of it in new
32 //free programs, and that you know you can do these things.
33 //
34 // To protect your rights, we need to prevent others from denying you
35 //these rights or asking you to surrender the rights. Therefore, you have
36 //certain responsibilities if you distribute copies of the software, or if
37 //you modify it: responsibilities to respect the freedom of others.
38 //
39 // For example, if you distribute copies of such a program, whether
40 //gratis or for a fee, you must pass on to the recipients the same
41 //freedoms that you received. You must make sure that they, too, receive
42 //or can get the source code. And you must show them these terms so they
43 //know their rights.
44 //
45 // Developers that use the GNU GPL protect your rights with two steps:
46 //(1) assert copyright on the software, and (2) offer you this License
47 //giving you legal permission to copy, distribute and/or modify it.
48 //
49 // For the developers' and authors' protection, the GPL clearly explains
50 //that there is no warranty for this free software. For both users' and
51 //authors' sake, the GPL requires that modified versions be marked as
52 //changed, so that their problems will not be attributed erroneously to
53 //authors of previous versions.
54 //
55 // Some devices are designed to deny users access to install or run
56 //modified versions of the software inside them, although the manufacturer
57 //can do so. This is fundamentally incompatible with the aim of
58 //protecting users' freedom to change the software. The systematic
59 //pattern of such abuse occurs in the area of products for individuals to
60 //use, which is precisely where it is most unacceptable. Therefore, we
61 //have designed this version of the GPL to prohibit the practice for those
62 //products. If such problems arise substantially in other domains, we
63 //stand ready to extend this provision to those domains in future versions
64 //of the GPL, as needed to protect the freedom of users.
65 //
66 // Finally, every program is threatened constantly by software patents.
67 //States should not allow patents to restrict development and use of
68 //software on general-purpose computers, but in those that do, we wish to
69 //avoid the special danger that patents applied to a free program could
70 //make it effectively proprietary. To prevent this, the GPL assures that
71 //patents cannot be used to render the program non-free.
72 //
73 // The precise terms and conditions for copying, distribution and
74 //modification follow.
75 //
76 // TERMS AND CONDITIONS
77 //
78 // 0. Definitions.
79 //
80 // "This License" refers to version 3 of the GNU General Public License.
81 //
82 // "Copyright" also means copyright-like laws that apply to other kinds of
83 //works, such as semiconductor masks.
84 //
85 // "The Program" refers to any copyrightable work licensed under this
86 //License. Each licensee is addressed as "you". "Licensees" and
87 //"recipients" may be individuals or organizations.
88 //
89 // To "modify" a work means to copy from or adapt all or part of the work
90 //in a fashion requiring copyright permission, other than the making of an
91 //exact copy. The resulting work is called a "modified version" of the
92 //earlier work or a work "based on" the earlier work.
93 //
94 // A "covered work" means either the unmodified Program or a work based
95 //on the Program.
96 //
97 // To "propagate" a work means to do anything with it that, without
98 //permission, would make you directly or secondarily liable for
99 //infringement under applicable copyright law, except executing it on a
100 //computer or modifying a private copy. Propagation includes copying,
101 //distribution (with or without modification), making available to the
102 //public, and in some countries other activities as well.
103 //
104 // To "convey" a work means any kind of propagation that enables other
105 //parties to make or receive copies. Mere interaction with a user through
106 //a computer network, with no transfer of a copy, is not conveying.
107 //
108 // An interactive user interface displays "Appropriate Legal Notices"
109 //to the extent that it includes a convenient and prominently visible
110 //feature that (1) displays an appropriate copyright notice, and (2)
111 //tells the user that there is no warranty for the work (except to the
112 //extent that warranties are provided), that licensees may convey the
113 //work under this License, and how to view a copy of this License. If
114 //the interface presents a list of user commands or options, such as a
115 //menu, a prominent item in the list meets this criterion.
116 //
117 // 1. Source Code.
118 //
119 // The "source code" for a work means the preferred form of the work
120 //for making modifications to it. "Object code" means any non-source
121 //form of a work.
122 //
123 // A "Standard Interface" means an interface that either is an official
124 //standard defined by a recognized standards body, or, in the case of
125 //interfaces specified for a particular programming language, one that
126 //is widely used among developers working in that language.
127 //
128 // The "System Libraries" of an executable work include anything, other
129 //than the work as a whole, that (a) is included in the normal form of
130 //packaging a Major Component, but which is not part of that Major
131 //Component, and (b) serves only to enable use of the work with that
132 //Major Component, or to implement a Standard Interface for which an
133 //implementation is available to the public in source code form. A
134 //"Major Component", in this context, means a major essential component
135 //(kernel, window system, and so on) of the specific operating system
136 //(if any) on which the executable work runs, or a compiler used to
137 //produce the work, or an object code interpreter used to run it.
138 //
139 // The "Corresponding Source" for a work in object code form means all
140 //the source code needed to generate, install, and (for an executable
141 //work) run the object code and to modify the work, including scripts to
142 //control those activities. However, it does not include the work's
143 //System Libraries, or general-purpose tools or generally available free
144 //programs which are used unmodified in performing those activities but
145 //which are not part of the work. For example, Corresponding Source
146 //includes interface definition files associated with source files for
147 //the work, and the source code for shared libraries and dynamically
148 //linked subprograms that the work is specifically designed to require,
149 //such as by intimate data communication or control flow between those
150 //subprograms and other parts of the work.
151 //
152 // The Corresponding Source need not include anything that users
153 //can regenerate automatically from other parts of the Corresponding
154 //Source.
155 //
156 // The Corresponding Source for a work in source code form is that
157 //same work.
158 //
159 // 2. Basic Permissions.
160 //
161 // All rights granted under this License are granted for the term of
162 //copyright on the Program, and are irrevocable provided the stated
163 //conditions are met. This License explicitly affirms your unlimited
164 //permission to run the unmodified Program. The output from running a
165 //covered work is covered by this License only if the output, given its
166 //content, constitutes a covered work. This License acknowledges your
167 //rights of fair use or other equivalent, as provided by copyright law.
168 //
169 // You may make, run and propagate covered works that you do not
170 //convey, without conditions so long as your license otherwise remains
171 //in force. You may convey covered works to others for the sole purpose
172 //of having them make modifications exclusively for you, or provide you
173 //with facilities for running those works, provided that you comply with
174 //the terms of this License in conveying all material for which you do
175 //not control copyright. Those thus making or running the covered works
176 //for you must do so exclusively on your behalf, under your direction
177 //and control, on terms that prohibit them from making any copies of
178 //your copyrighted material outside their relationship with you.
179 //
180 // Conveying under any other circumstances is permitted solely under
181 //the conditions stated below. Sublicensing is not allowed; section 10
182 //makes it unnecessary.
183 //
184 // 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
185 //
186 // No covered work shall be deemed part of an effective technological
187 //measure under any applicable law fulfilling obligations under article
188 //11 of the WIPO copyright treaty adopted on 20 December 1996, or
189 //similar laws prohibiting or restricting circumvention of such
190 //measures.
191 //
192 // When you convey a covered work, you waive any legal power to forbid
193 //circumvention of technological measures to the extent such circumvention
194 //is effected by exercising rights under this License with respect to
195 //the covered work, and you disclaim any intention to limit operation or
196 //modification of the work as a means of enforcing, against the work's
197 //users, your or third parties' legal rights to forbid circumvention of
198 //technological measures.
199 //
200 // 4. Conveying Verbatim Copies.
201 //
202 // You may convey verbatim copies of the Program's source code as you
203 //receive it, in any medium, provided that you conspicuously and
204 //appropriately publish on each copy an appropriate copyright notice;
205 //keep intact all notices stating that this License and any
206 //non-permissive terms added in accord with section 7 apply to the code;
207 //keep intact all notices of the absence of any warranty; and give all
208 //recipients a copy of this License along with the Program.
209 //
210 // You may charge any price or no price for each copy that you convey,
211 //and you may offer support or warranty protection for a fee.
212 //
213 // 5. Conveying Modified Source Versions.
214 //
215 // You may convey a work based on the Program, or the modifications to
216 //produce it from the Program, in the form of source code under the
217 //terms of section 4, provided that you also meet all of these conditions:
218 //
219 // a) The work must carry prominent notices stating that you modified
220 // it, and giving a relevant date.
221 //
222 // b) The work must carry prominent notices stating that it is
223 // released under this License and any conditions added under section
224 // 7. This requirement modifies the requirement in section 4 to
225 // "keep intact all notices".
226 //
227 // c) You must license the entire work, as a whole, under this
228 // License to anyone who comes into possession of a copy. This
229 // License will therefore apply, along with any applicable section 7
230 // additional terms, to the whole of the work, and all its parts,
231 // regardless of how they are packaged. This License gives no
232 // permission to license the work in any other way, but it does not
233 // invalidate such permission if you have separately received it.
234 //
235 // d) If the work has interactive user interfaces, each must display
236 // Appropriate Legal Notices; however, if the Program has interactive
237 // interfaces that do not display Appropriate Legal Notices, your
238 // work need not make them do so.
239 //
240 // 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 //"aggregate" 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.
249 //
250 // 6. Conveying Non-Source Forms.
251 //
252 // 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:
256 //
257 // a) Convey the object code in, or embodied in, a physical product
258 // (including a physical distribution medium), accompanied by the
259 // Corresponding Source fixed on a durable physical medium
260 // customarily used for software interchange.
261 //
262 // b) Convey the object code in, or embodied in, a physical product
263 // (including a physical distribution medium), accompanied by a
264 // written offer, valid for at least three years and valid for as
265 // long as you offer spare parts or customer support for that product
266 // model, to give anyone who possesses the object code either (1) a
267 // copy of the Corresponding Source for all the software in the
268 // product that is covered by this License, on a durable physical
269 // medium customarily used for software interchange, for a price no
270 // more than your reasonable cost of physically performing this
271 // conveying of source, or (2) access to copy the
272 // Corresponding Source from a network server at no charge.
273 //
274 // c) Convey individual copies of the object code with a copy of the
275 // written offer to provide the Corresponding Source. This
276 // alternative is allowed only occasionally and noncommercially, and
277 // only if you received the object code with such an offer, in accord
278 // with subsection 6b.
279 //
280 // d) Convey the object code by offering access from a designated
281 // place (gratis or for a charge), and offer equivalent access to the
282 // Corresponding Source in the same way through the same place at no
283 // further charge. You need not require recipients to copy the
284 // Corresponding Source along with the object code. If the place to
285 // copy the object code is a network server, the Corresponding Source
286 // may be on a different server (operated by you or a third party)
287 // that supports equivalent copying facilities, provided you maintain
288 // clear directions next to the object code saying where to find the
289 // Corresponding Source. Regardless of what server hosts the
290 // Corresponding Source, you remain obligated to ensure that it is
291 // available for as long as needed to satisfy these requirements.
292 //
293 // e) Convey the object code using peer-to-peer transmission, provided
294 // you inform other peers where the object code and Corresponding
295 // Source of the work are being offered to the general public at no
296 // charge under subsection 6d.
297 //
298 // A separable portion of the object code, whose source code is excluded
299 //from the Corresponding Source as a System Library, need not be
300 //included in conveying the object code work.
301 //
302 // A "User Product" is either (1) a "consumer product", which means any
303 //tangible personal property which is normally used for personal, family,
304 //or household purposes, or (2) anything designed or sold for incorporation
305 //into a dwelling. In determining whether a product is a consumer product,
306 //doubtful cases shall be resolved in favor of coverage. For a particular
307 //product received by a particular user, "normally used" refers to a
308 //typical or common use of that class of product, regardless of the status
309 //of the particular user or of the way in which the particular user
310 //actually uses, or expects or is expected to use, the product. A product
311 //is a consumer product regardless of whether the product has substantial
312 //commercial, industrial or non-consumer uses, unless such uses represent
313 //the only significant mode of use of the product.
314 //
315 // "Installation Information" for a User Product means any methods,
316 //procedures, authorization keys, or other information required to install
317 //and execute modified versions of a covered work in that User Product from
318 //a modified version of its Corresponding Source. The information must
319 //suffice to ensure that the continued functioning of the modified object
320 //code is in no case prevented or interfered with solely because
321 //modification has been made.
322 //
323 // If you convey an object code work under this section in, or with, or
324 //specifically for use in, a User Product, and the conveying occurs as
325 //part of a transaction in which the right of possession and use of the
326 //User Product is transferred to the recipient in perpetuity or for a
327 //fixed term (regardless of how the transaction is characterized), the
328 //Corresponding Source conveyed under this section must be accompanied
329 //by the Installation Information. But this requirement does not apply
330 //if neither you nor any third party retains the ability to install
331 //modified object code on the User Product (for example, the work has
332 //been installed in ROM).
333 //
334 // The requirement to provide Installation Information does not include a
335 //requirement to continue to provide support service, warranty, or updates
336 //for a work that has been modified or installed by the recipient, or for
337 //the User Product in which it has been modified or installed. Access to a
338 //network may be denied when the modification itself materially and
339 //adversely affects the operation of the network or violates the rules and
340 //protocols for communication across the network.
341 //
342 // Corresponding Source conveyed, and Installation Information provided,
343 //in accord with this section must be in a format that is publicly
344 //documented (and with an implementation available to the public in
345 //source code form), and must require no special password or key for
346 //unpacking, reading or copying.
347 //
348 // 7. Additional Terms.
349 //
350 // "Additional permissions" are terms that supplement the terms of this
351 //License by making exceptions from one or more of its conditions.
352 //Additional permissions that are applicable to the entire Program shall
353 //be treated as though they were included in this License, to the extent
354 //that they are valid under applicable law. If additional permissions
355 //apply only to part of the Program, that part may be used separately
356 //under those permissions, but the entire Program remains governed by
357 //this License without regard to the additional permissions.
358 //
359 // When you convey a copy of a covered work, you may at your option
360 //remove any additional permissions from that copy, or from any part of
361 //it. (Additional permissions may be written to require their own
362 //removal in certain cases when you modify the work.) You may place
363 //additional permissions on material, added by you to a covered work,
364 //for which you have or can give appropriate copyright permission.
365 //
366 // Notwithstanding any other provision of this License, for material you
367 //add to a covered work, you may (if authorized by the copyright holders of
368 //that material) supplement the terms of this License with terms:
369 //
370 // a) Disclaiming warranty or limiting liability differently from the
371 // terms of sections 15 and 16 of this License; or
372 //
373 // b) Requiring preservation of specified reasonable legal notices or
374 // author attributions in that material or in the Appropriate Legal
375 // Notices displayed by works containing it; or
376 //
377 // c) Prohibiting misrepresentation of the origin of that material, or
378 // requiring that modified versions of such material be marked in
379 // reasonable ways as different from the original version; or
380 //
381 // d) Limiting the use for publicity purposes of names of licensors or
382 // authors of the material; or
383 //
384 // e) Declining to grant rights under trademark law for use of some
385 // trade names, trademarks, or service marks; or
386 //
387 // f) Requiring indemnification of licensors and authors of that
388 // material by anyone who conveys the material (or modified versions of
389 // it) with contractual assumptions of liability to the recipient, for
390 // any liability that these contractual assumptions directly impose on
391 // those licensors and authors.
392 //
393 // All other non-permissive additional terms are considered "further
394 //restrictions" within the meaning of section 10. If the Program as you
395 //received it, or any part of it, contains a notice stating that it is
396 //governed by this License along with a term that is a further
397 //restriction, you may remove that term. If a license document contains
398 //a further restriction but permits relicensing or conveying under this
399 //License, you may add to a covered work material governed by the terms
400 //of that license document, provided that the further restriction does
401 //not survive such relicensing or conveying.
402 //
403 // If you add terms to a covered work in accord with this section, you
404 //must place, in the relevant source files, a statement of the
405 //additional terms that apply to those files, or a notice indicating
406 //where to find the applicable terms.
407 //
408 // Additional terms, permissive or non-permissive, may be stated in the
409 //form of a separately written license, or stated as exceptions;
410 //the above requirements apply either way.
411 //
412 // 8. Termination.
413 //
414 // You may not propagate or modify a covered work except as expressly
415 //provided under this License. Any attempt otherwise to propagate or
416 //modify it is void, and will automatically terminate your rights under
417 //this License (including any patent licenses granted under the third
418 //paragraph of section 11).
419 //
420 // However, if you cease all violation of this License, then your
421 //license from a particular copyright holder is reinstated (a)
422 //provisionally, unless and until the copyright holder explicitly and
423 //finally terminates your license, and (b) permanently, if the copyright
424 //holder fails to notify you of the violation by some reasonable means
425 //prior to 60 days after the cessation.
426 //
427 // Moreover, your license from a particular copyright holder is
428 //reinstated permanently if the copyright holder notifies you of the
429 //violation by some reasonable means, this is the first time you have
430 //received notice of violation of this License (for any work) from that
431 //copyright holder, and you cure the violation prior to 30 days after
432 //your receipt of the notice.
433 //
434 // Termination of your rights under this section does not terminate the
435 //licenses of parties who have received copies or rights from you under
436 //this License. If your rights have been terminated and not permanently
437 //reinstated, you do not qualify to receive new licenses for the same
438 //material under section 10.
439 //
440 // 9. Acceptance Not Required for Having Copies.
441 //
442 // You are not required to accept this License in order to receive or
443 //run a copy of the Program. Ancillary propagation of a covered work
444 //occurring solely as a consequence of using peer-to-peer transmission
445 //to receive a copy likewise does not require acceptance. However,
446 //nothing other than this License grants you permission to propagate or
447 //modify any covered work. These actions infringe copyright if you do
448 //not accept this License. Therefore, by modifying or propagating a
449 //covered work, you indicate your acceptance of this License to do so.
450 //
451 // 10. Automatic Licensing of Downstream Recipients.
452 //
453 // Each time you convey a covered work, the recipient automatically
454 //receives a license from the original licensors, to run, modify and
455 //propagate that work, subject to this License. You are not responsible
456 //for enforcing compliance by third parties with this License.
457 //
458 // An "entity transaction" is a transaction transferring control of an
459 //organization, or substantially all assets of one, or subdividing an
460 //organization, or merging organizations. If propagation of a covered
461 //work results from an entity transaction, each party to that
462 //transaction who receives a copy of the work also receives whatever
463 //licenses to the work the party's predecessor in interest had or could
464 //give under the previous paragraph, plus a right to possession of the
465 //Corresponding Source of the work from the predecessor in interest, if
466 //the predecessor has it or can get it with reasonable efforts.
467 //
468 // You may not impose any further restrictions on the exercise of the
469 //rights granted or affirmed under this License. For example, you may
470 //not impose a license fee, royalty, or other charge for exercise of
471 //rights granted under this License, and you may not initiate litigation
472 //(including a cross-claim or counterclaim in a lawsuit) alleging that
473 //any patent claim is infringed by making, using, selling, offering for
474 //sale, or importing the Program or any portion of it.
475 //
476 // 11. Patents.
477 //
478 // A "contributor" is a copyright holder who authorizes use under this
479 //License of the Program or a work on which the Program is based. The
480 //work thus licensed is called the contributor's "contributor version".
481 //
482 // A contributor's "essential patent claims" are all patent claims
483 //owned or controlled by the contributor, whether already acquired or
484 //hereafter acquired, that would be infringed by some manner, permitted
485 //by this License, of making, using, or selling its contributor version,
486 //but do not include claims that would be infringed only as a
487 //consequence of further modification of the contributor version. For
488 //purposes of this definition, "control" includes the right to grant
489 //patent sublicenses in a manner consistent with the requirements of
490 //this License.
491 //
492 // Each contributor grants you a non-exclusive, worldwide, royalty-free
493 //patent license under the contributor's essential patent claims, to
494 //make, use, sell, offer for sale, import and otherwise run, modify and
495 //propagate the contents of its contributor version.
496 //
497 // In the following three paragraphs, a "patent license" is any express
498 //agreement or commitment, however denominated, not to enforce a patent
499 //(such as an express permission to practice a patent or covenant not to
500 //sue for patent infringement). To "grant" such a patent license to a
501 //party means to make such an agreement or commitment not to enforce a
502 //patent against the party.
503 //
504 // If you convey a covered work, knowingly relying on a patent license,
505 //and the Corresponding Source of the work is not available for anyone
506 //to copy, free of charge and under the terms of this License, through a
507 //publicly available network server or other readily accessible means,
508 //then you must either (1) cause the Corresponding Source to be so
509 //available, or (2) arrange to deprive yourself of the benefit of the
510 //patent license for this particular work, or (3) arrange, in a manner
511 //consistent with the requirements of this License, to extend the patent
512 //license to downstream recipients. "Knowingly relying" means you have
513 //actual knowledge that, but for the patent license, your conveying the
514 //covered work in a country, or your recipient's use of the covered work
515 //in a country, would infringe one or more identifiable patents in that
516 //country that you have reason to believe are valid.
517 //
518 // If, pursuant to or in connection with a single transaction or
519 //arrangement, you convey, or propagate by procuring conveyance of, a
520 //covered work, and grant a patent license to some of the parties
521 //receiving the covered work authorizing them to use, propagate, modify
522 //or convey a specific copy of the covered work, then the patent license
523 //you grant is automatically extended to all recipients of the covered
524 //work and works based on it.
525 //
526 // A patent license is "discriminatory" if it does not include within
527 //the scope of its coverage, prohibits the exercise of, or is
528 //conditioned on the non-exercise of one or more of the rights that are
529 //specifically granted under this License. You may not convey a covered
530 //work if you are a party to an arrangement with a third party that is
531 //in the business of distributing software, under which you make payment
532 //to the third party based on the extent of your activity of conveying
533 //the work, and under which the third party grants, to any of the
534 //parties who would receive the covered work from you, a discriminatory
535 //patent license (a) in connection with copies of the covered work
536 //conveyed by you (or copies made from those copies), or (b) primarily
537 //for and in connection with specific products or compilations that
538 //contain the covered work, unless you entered into that arrangement,
539 //or that patent license was granted, prior to 28 March 2007.
540 //
541 // Nothing in this License shall be construed as excluding or limiting
542 //any implied license or other defenses to infringement that may
543 //otherwise be available to you under applicable patent law.
544 //
545 // 12. No Surrender of Others' Freedom.
546 //
547 // If conditions are imposed on you (whether by court order, agreement or
548 //otherwise) that contradict the conditions of this License, they do not
549 //excuse you from the conditions of this License. If you cannot convey a
550 //covered work so as to satisfy simultaneously your obligations under this
551 //License and any other pertinent obligations, then as a consequence you may
552 //not convey it at all. For example, if you agree to terms that obligate you
553 //to collect a royalty for further conveying from those to whom you convey
554 //the Program, the only way you could satisfy both those terms and this
555 //License would be to refrain entirely from conveying the Program.
556 //
557 // 13. Use with the GNU Affero General Public License.
558 //
559 // Notwithstanding any other provision of this License, you have
560 //permission to link or combine any covered work with a work licensed
561 //under version 3 of the GNU Affero General Public License into a single
562 //combined work, and to convey the resulting work. The terms of this
563 //License will continue to apply to the part which is the covered work,
564 //but the special requirements of the GNU Affero General Public License,
565 //section 13, concerning interaction through a network will apply to the
566 //combination as such.
567 //
568 // 14. Revised Versions of this License.
569 //
570 // The Free Software Foundation may publish revised and/or new versions of
571 //the GNU General Public License from time to time. Such new versions will
572 //be similar in spirit to the present version, but may differ in detail to
573 //address new problems or concerns.
574 //
575 // Each version is given a distinguishing version number. If the
576 //Program specifies that a certain numbered version of the GNU General
577 //Public License "or any later version" applies to it, you have the
578 //option of following the terms and conditions either of that numbered
579 //version or of any later version published by the Free Software
580 //Foundation. If the Program does not specify a version number of the
581 //GNU General Public License, you may choose any version ever published
582 //by the Free Software Foundation.
583 //
584 // If the Program specifies that a proxy can decide which future
585 //versions of the GNU General Public License can be used, that proxy's
586 //public statement of acceptance of a version permanently authorizes you
587 //to choose that version for the Program.
588 //
589 // Later license versions may give you additional or different
590 //permissions. However, no additional obligations are imposed on any
591 //author or copyright holder as a result of your choosing to follow a
592 //later version.
593 //
594 // 15. Disclaimer of Warranty.
595 //
596 // THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
597 //APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
598 //HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
599 //OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
600 //THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
601 //PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
602 //IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
603 //ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
604 //
605 // 16. Limitation of Liability.
606 //
607 // IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
608 //WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
609 //THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
610 //GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
611 //USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
612 //DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
613 //PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
614 //EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
615 //SUCH DAMAGES.
616 //
617 // 17. Interpretation of Sections 15 and 16.
618 //
619 // If the disclaimer of warranty and limitation of liability provided
620 //above cannot be given local legal effect according to their terms,
621 //reviewing courts shall apply local law that most closely approximates
622 //an absolute waiver of all civil liability in connection with the
623 //Program, unless a warranty or assumption of liability accompanies a
624 //copy of the Program in return for a fee.
625 //
626 // END OF TERMS AND CONDITIONS
627 //
628 // How to Apply These Terms to Your New Programs
629 //
630 // If you develop a new program, and you want it to be of the greatest
631 //possible use to the public, the best way to achieve this is to make it
632 //free software which everyone can redistribute and change under these terms.
633 //
634 // To do so, attach the following notices to the program. It is safest
635 //to attach them to the start of each source file to most effectively
636 //state the exclusion of warranty; and each file should have at least
637 //the "copyright" line and a pointer to where the full notice is found.
638 //
639 // <one line to give the program's name and a brief idea of what it does.>
640 // Copyright (C) <year> <name of author>
641 //
642 // This program is free software: you can redistribute it and/or modify
643 // it under the terms of the GNU General Public License as published by
644 // the Free Software Foundation, either version 3 of the License, or
645 // (at your option) any later version.
646 //
647 // This program is distributed in the hope that it will be useful,
648 // but WITHOUT ANY WARRANTY; without even the implied warranty of
649 // MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
650 // GNU General Public License for more details.
651 //
652 // You should have received a copy of the GNU General Public License
653 // along with this program. If not, see <http://www.gnu.org/licenses/>.
654 //
655 //Also add information on how to contact you by electronic and paper mail.
656 //
657 // If the program does terminal interaction, make it output a short
658 //notice like this when it starts in an interactive mode:
659 //
660 // <program> Copyright (C) <year> <name of author>
661 // This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
662 // This is free software, and you are welcome to redistribute it
663 // under certain conditions; type `show c' for details.
664 //
665 //The hypothetical commands `show w' and `show c' should show the appropriate
666 //parts of the General Public License. Of course, your program's commands
667 //might be different; for a GUI interface, you would use an "about box".
668 //
669 // You should also get your employer (if you work as a programmer) or school,
670 //if any, to sign a "copyright disclaimer" for the program, if necessary.
671 //For more information on this, and how to apply and follow the GNU GPL, see
672 //<http://www.gnu.org/licenses/>.
673 //
674 // The GNU General Public License does not permit incorporating your program
675 //into proprietary programs. If your program is a subroutine library, you
676 //may consider it more useful to permit linking proprietary applications with
677 //the library. If this is what you want to do, use the GNU Lesser General
678 //Public License instead of this License. But first, please read
