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     //
