9     //PUBLIC LICENSE, Version 3, full license text below.

11     // GNU GENERAL PUBLIC LICENSE
12     // Version 3, 29 June 2007
13     //
14     // Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
15     // Everyone is permitted to copy and distribute verbatim copies
16     // of this license document, but changing it is not allowed.
17     //
18     // Preamble
19     //
20     // The GNU General Public License is a free, copyleft license for
21     //software and other kinds of works.
22     //
23     // The licenses for most software and other practical works are designed
24     //to take away your freedom to share and change the works. By contrast,
25     //the GNU General Public License is intended to guarantee your freedom to
26     //share and change all versions of a program--to make sure it remains free
27     //software for all its users. We, the Free Software Foundation, use the
28     //GNU General Public License for most of our software; it applies also to
29     //any other work released this way by its authors. You can apply it to
30     //your programs, too.
31     //
32     // When we speak of free software, we are referring to freedom, not
33     //price. Our General Public Licenses are designed to make sure that you
34     //have the freedom to distribute copies of free software (and charge for
35     //them if you wish), that you receive source code or can get it if you
36     //want it, that you can change the software or use pieces of it in new
37     //free programs, and that you know you can do these things.
38     //
39     // To protect your rights, we need to prevent others from denying you
40     //these rights or asking you to surrender the rights. Therefore, you have
41     //certain responsibilities if you distribute copies of the software, or if
42     //you modify it: responsibilities to respect the freedom of others.
43     //
44     // For example, if you distribute copies of such a program, whether
45     //gratis or for a fee, you must pass on to the recipients the same
46     //freedoms that you received. You must make sure that they, too, receive
47     //or can get the source code. And you must show them these terms so they
48     //know their rights.
49     //
50     // Developers that use the GNU GPL protect your rights with two steps:
51     //(1) assert copyright on the software, and (2) offer you this License
52     //giving you legal permission to copy, distribute and/or modify it.
53     //
54     // For the developers' and authors' protection, the GPL clearly explains
55     //that there is no warranty for this free software. For both users' and
56     //authors' sake, the GPL requires that modified versions be marked as
57     //changed, so that their problems will not be attributed erroneously to
58     //authors of previous versions.
59     //
60     // Some devices are designed to deny users access to install or run
61     //modified versions of the software inside them, although the manufacturer
62     //can do so. This is fundamentally incompatible with the aim of
63     //protecting users' freedom to change the software. The systematic
64     //pattern of such abuse occurs in the area of products for individuals to
65     //use, which is precisely where it is most unacceptable. Therefore, we
66     //have designed this version of the GPL to prohibit the practice for those
67     //products. If such problems arise substantially in other domains, we
68     //stand ready to extend this provision to those domains in future versions
69     //of the GPL, as needed to protect the freedom of users.
70     //
71     // Finally, every program is threatened constantly by software patents.
72     //States should not allow patents to restrict development and use of
73     //software on general-purpose computers, but in those that do, we wish to
74     //avoid the special danger that patents applied to a free program could
75     //make it effectively proprietary. To prevent this, the GPL assures that
76     //patents cannot be used to render the program non-free.
77     //
78     // The precise terms and conditions for copying, distribution and
79     //modification follow.
80     //
81     // TERMS AND CONDITIONS
82     //
83     // 0. Definitions.
84     //
85     // "This License" refers to version 3 of the GNU General Public License.
86     //
87     // "Copyright" also means copyright-like laws that apply to other kinds of
88     //works, such as semiconductor masks.
89     //
90     // "The Program" refers to any copyrightable work licensed under this
91     //License. Each licensee is addressed as "you". "Licensees" and
92     //"recipients" may be individuals or organizations.
93     //
94     // To "modify" a work means to copy from or adapt all or part of the work
95     //in a fashion requiring copyright permission, other than the making of an
96     //exact copy. The resulting work is called a "modified version" of the
97     //earlier work or a work "based on" the earlier work.
98     //
99     // A "covered work" means either the unmodified Program or a work based
100     //on the Program.
101     //
102     // To "propagate" a work means to do anything with it that, without
103     //permission, would make you directly or secondarily liable for
104     //infringement under applicable copyright law, except executing it on a
105     //computer or modifying a private copy. Propagation includes copying,
106     //distribution (with or without modification), making available to the
107     //public, and in some countries other activities as well.
108     //
109     // To "convey" a work means any kind of propagation that enables other
110     //parties to make or receive copies. Mere interaction with a user through
111     //a computer network, with no transfer of a copy, is not conveying.
112     //
113     // An interactive user interface displays "Appropriate Legal Notices"
114     //to the extent that it includes a convenient and prominently visible
115     //feature that (1) displays an appropriate copyright notice, and (2)
116     //tells the user that there is no warranty for the work (except to the
117     //extent that warranties are provided), that licensees may convey the
118     //work under this License, and how to view a copy of this License. If
119     //the interface presents a list of user commands or options, such as a
120     //menu, a prominent item in the list meets this criterion.
121     //
122     // 1. Source Code.
123     //
124     // The "source code" for a work means the preferred form of the work
125     //for making modifications to it. "Object code" means any non-source
126     //form of a work.
127     //
128     // A "Standard Interface" means an interface that either is an official
129     //standard defined by a recognized standards body, or, in the case of
130     //interfaces specified for a particular programming language, one that
131     //is widely used among developers working in that language.
132     //
133     // The "System Libraries" of an executable work include anything, other
134     //than the work as a whole, that (a) is included in the normal form of
135     //packaging a Major Component, but which is not part of that Major
136     //Component, and (b) serves only to enable use of the work with that
137     //Major Component, or to implement a Standard Interface for which an
138     //implementation is available to the public in source code form. A
139     //"Major Component", in this context, means a major essential component
140     //(kernel, window system, and so on) of the specific operating system
141     //(if any) on which the executable work runs, or a compiler used to
142     //produce the work, or an object code interpreter used to run it.
143     //
144     // The "Corresponding Source" for a work in object code form means all
145     //the source code needed to generate, install, and (for an executable
146     //work) run the object code and to modify the work, including scripts to
147     //control those activities. However, it does not include the work's
148     //System Libraries, or general-purpose tools or generally available free
149     //programs which are used unmodified in performing those activities but
150     //which are not part of the work. For example, Corresponding Source
151     //includes interface definition files associated with source files for
152     //the work, and the source code for shared libraries and dynamically
153     //linked subprograms that the work is specifically designed to require,
154     //such as by intimate data communication or control flow between those
155     //subprograms and other parts of the work.
156     //
157     // The Corresponding Source need not include anything that users
158     //can regenerate automatically from other parts of the Corresponding
159     //Source.
160     //
161     // The Corresponding Source for a work in source code form is that
162     //same work.
163     //
164     // 2. Basic Permissions.
165     //
166     // All rights granted under this License are granted for the term of
167     //copyright on the Program, and are irrevocable provided the stated
168     //conditions are met. This License explicitly affirms your unlimited
169     //permission to run the unmodified Program. The output from running a
170     //covered work is covered by this License only if the output, given its
171     //content, constitutes a covered work. This License acknowledges your
172     //rights of fair use or other equivalent, as provided by copyright law.
173     //
174     // You may make, run and propagate covered works that you do not
175     //convey, without conditions so long as your license otherwise remains
176     //in force. You may convey covered works to others for the sole purpose
177     //of having them make modifications exclusively for you, or provide you
178     //with facilities for running those works, provided that you comply with
179     //the terms of this License in conveying all material for which you do
180     //not control copyright. Those thus making or running the covered works
181     //for you must do so exclusively on your behalf, under your direction
182     //and control, on terms that prohibit them from making any copies of
183     //your copyrighted material outside their relationship with you.
184     //
185     // Conveying under any other circumstances is permitted solely under
186     //the conditions stated below. Sublicensing is not allowed; section 10
187     //makes it unnecessary.
188     //
189     // 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
190     //
191     // No covered work shall be deemed part of an effective technological
192     //measure under any applicable law fulfilling obligations under article
193     //11 of the WIPO copyright treaty adopted on 20 December 1996, or
194     //similar laws prohibiting or restricting circumvention of such
195     //measures.
196     //
197     // When you convey a covered work, you waive any legal power to forbid
198     //circumvention of technological measures to the extent such circumvention
199     //is effected by exercising rights under this License with respect to
200     //the covered work, and you disclaim any intention to limit operation or
201     //modification of the work as a means of enforcing, against the work's
202     //users, your or third parties' legal rights to forbid circumvention of
203     //technological measures.
204     //
205     // 4. Conveying Verbatim Copies.
206     //
207     // You may convey verbatim copies of the Program's source code as you
208     //receive it, in any medium, provided that you conspicuously and
209     //appropriately publish on each copy an appropriate copyright notice;
210     //keep intact all notices stating that this License and any
211     //non-permissive terms added in accord with section 7 apply to the code;
212     //keep intact all notices of the absence of any warranty; and give all
213     //recipients a copy of this License along with the Program.
214     //
215     // You may charge any price or no price for each copy that you convey,
216     //and you may offer support or warranty protection for a fee.
217     //
218     // 5. Conveying Modified Source Versions.
219     //
220     // You may convey a work based on the Program, or the modifications to
221     //produce it from the Program, in the form of source code under the
222     //terms of section 4, provided that you also meet all of these conditions:
223     //
224     // a) The work must carry prominent notices stating that you modified
225     // it, and giving a relevant date.
226     //
227     // b) The work must carry prominent notices stating that it is
228     // released under this License and any conditions added under section
229     // 7. This requirement modifies the requirement in section 4 to
230     // "keep intact all notices".
231     //
232     // c) You must license the entire work, as a whole, under this
233     // License to anyone who comes into possession of a copy. This
234     // License will therefore apply, along with any applicable section 7
235     // additional terms, to the whole of the work, and all its parts,
236     // regardless of how they are packaged. This License gives no
237     // permission to license the work in any other way, but it does not
238     // invalidate such permission if you have separately received it.
239     //
240     // d) If the work has interactive user interfaces, each must display
241     // Appropriate Legal Notices; however, if the Program has interactive
242     // interfaces that do not display Appropriate Legal Notices, your
243     // work need not make them do so.
244     //
245     // A compilation of a covered work with other separate and independent
246     //works, which are not by their nature extensions of the covered work,
247     //and which are not combined with it such as to form a larger program,
248     //in or on a volume of a storage or distribution medium, is called an
249     //"aggregate" if the compilation and its resulting copyright are not
250     //used to limit the access or legal rights of the compilation's users
251     //beyond what the individual works permit. Inclusion of a covered work
252     //in an aggregate does not cause this License to apply to the other
253     //parts of the aggregate.
254     //
255     // 6. Conveying Non-Source Forms.
256     //
257     // You may convey a covered work in object code form under the terms
258     //of sections 4 and 5, provided that you also convey the
259     //machine-readable Corresponding Source under the terms of this License,
260     //in one of these ways:
261     //
262     // a) Convey the object code in, or embodied in, a physical product
263     // (including a physical distribution medium), accompanied by the
264     // Corresponding Source fixed on a durable physical medium
265     // customarily used for software interchange.
266     //
267     // b) Convey the object code in, or embodied in, a physical product
268     // (including a physical distribution medium), accompanied by a
269     // written offer, valid for at least three years and valid for as
270     // long as you offer spare parts or customer support for that product
271     // model, to give anyone who possesses the object code either (1) a
272     // copy of the Corresponding Source for all the software in the
273     // product that is covered by this License, on a durable physical
274     // medium customarily used for software interchange, for a price no
275     // more than your reasonable cost of physically performing this
276     // conveying of source, or (2) access to copy the
277     // Corresponding Source from a network server at no charge.
278     //
279     // c) Convey individual copies of the object code with a copy of the
280     // written offer to provide the Corresponding Source. This
281     // alternative is allowed only occasionally and noncommercially, and
282     // only if you received the object code with such an offer, in accord
283     // with subsection 6b.
284     //
285     // d) Convey the object code by offering access from a designated
286     // place (gratis or for a charge), and offer equivalent access to the
287     // Corresponding Source in the same way through the same place at no
288     // further charge. You need not require recipients to copy the
289     // Corresponding Source along with the object code. If the place to
290     // copy the object code is a network server, the Corresponding Source
291     // may be on a different server (operated by you or a third party)
292     // that supports equivalent copying facilities, provided you maintain
293     // clear directions next to the object code saying where to find the
294     // Corresponding Source. Regardless of what server hosts the
295     // Corresponding Source, you remain obligated to ensure that it is
296     // available for as long as needed to satisfy these requirements.
297     //
298     // e) Convey the object code using peer-to-peer transmission, provided
299     // you inform other peers where the object code and Corresponding
300     // Source of the work are being offered to the general public at no
301     // charge under subsection 6d.
302     //
303     // A separable portion of the object code, whose source code is excluded
304     //from the Corresponding Source as a System Library, need not be
305     //included in conveying the object code work.
306     //
307     // A "User Product" is either (1) a "consumer product", which means any
308     //tangible personal property which is normally used for personal, family,
309     //or household purposes, or (2) anything designed or sold for incorporation
310     //into a dwelling. In determining whether a product is a consumer product,
311     //doubtful cases shall be resolved in favor of coverage. For a particular
312     //product received by a particular user, "normally used" refers to a
313     //typical or common use of that class of product, regardless of the status
314     //of the particular user or of the way in which the particular user
315     //actually uses, or expects or is expected to use, the product. A product
316     //is a consumer product regardless of whether the product has substantial
317     //commercial, industrial or non-consumer uses, unless such uses represent
318     //the only significant mode of use of the product.
319     //
320     // "Installation Information" for a User Product means any methods,
321     //procedures, authorization keys, or other information required to install
322     //and execute modified versions of a covered work in that User Product from
323     //a modified version of its Corresponding Source. The information must
324     //suffice to ensure that the continued functioning of the modified object
325     //code is in no case prevented or interfered with solely because
326     //modification has been made.
327     //
328     // If you convey an object code work under this section in, or with, or
329     //specifically for use in, a User Product, and the conveying occurs as
330     //part of a transaction in which the right of possession and use of the
331     //User Product is transferred to the recipient in perpetuity or for a
332     //fixed term (regardless of how the transaction is characterized), the
333     //Corresponding Source conveyed under this section must be accompanied
334     //by the Installation Information. But this requirement does not apply
335     //if neither you nor any third party retains the ability to install
336     //modified object code on the User Product (for example, the work has
337     //been installed in ROM).
338     //
339     // The requirement to provide Installation Information does not include a
340     //requirement to continue to provide support service, warranty, or updates
341     //for a work that has been modified or installed by the recipient, or for
342     //the User Product in which it has been modified or installed. Access to a
343     //network may be denied when the modification itself materially and
344     //adversely affects the operation of the network or violates the rules and
345     //protocols for communication across the network.
346     //
347     // Corresponding Source conveyed, and Installation Information provided,
348     //in accord with this section must be in a format that is publicly
349     //documented (and with an implementation available to the public in
350     //source code form), and must require no special password or key for
351     //unpacking, reading or copying.
352     //
353     // 7. Additional Terms.
354     //
355     // "Additional permissions" are terms that supplement the terms of this
356     //License by making exceptions from one or more of its conditions.
357     //Additional permissions that are applicable to the entire Program shall
358     //be treated as though they were included in this License, to the extent
359     //that they are valid under applicable law. If additional permissions
360     //apply only to part of the Program, that part may be used separately
361     //under those permissions, but the entire Program remains governed by
362     //this License without regard to the additional permissions.
363     //
364     // When you convey a copy of a covered work, you may at your option
365     //remove any additional permissions from that copy, or from any part of
366     //it. (Additional permissions may be written to require their own
367     //removal in certain cases when you modify the work.) You may place
368     //additional permissions on material, added by you to a covered work,
369     //for which you have or can give appropriate copyright permission.
370     //
371     // Notwithstanding any other provision of this License, for material you
372     //add to a covered work, you may (if authorized by the copyright holders of
373     //that material) supplement the terms of this License with terms:
374     //
375     // a) Disclaiming warranty or limiting liability differently from the
376     // terms of sections 15 and 16 of this License; or
377     //
378     // b) Requiring preservation of specified reasonable legal notices or
379     // author attributions in that material or in the Appropriate Legal
380     // Notices displayed by works containing it; or
381     //
382     // c) Prohibiting misrepresentation of the origin of that material, or
383     // requiring that modified versions of such material be marked in
384     // reasonable ways as different from the original version; or
385     //
386     // d) Limiting the use for publicity purposes of names of licensors or
387     // authors of the material; or
388     //
389     // e) Declining to grant rights under trademark law for use of some
390     // trade names, trademarks, or service marks; or
391     //
392     // f) Requiring indemnification of licensors and authors of that
393     // material by anyone who conveys the material (or modified versions of
394     // it) with contractual assumptions of liability to the recipient, for
395     // any liability that these contractual assumptions directly impose on
396     // those licensors and authors.
397     //
398     // All other non-permissive additional terms are considered "further
399     //restrictions" within the meaning of section 10. If the Program as you
400     //received it, or any part of it, contains a notice stating that it is
401     //governed by this License along with a term that is a further
402     //restriction, you may remove that term. If a license document contains
403     //a further restriction but permits relicensing or conveying under this
404     //License, you may add to a covered work material governed by the terms
405     //of that license document, provided that the further restriction does
406     //not survive such relicensing or conveying.
407     //
408     // If you add terms to a covered work in accord with this section, you
409     //must place, in the relevant source files, a statement of the
410     //additional terms that apply to those files, or a notice indicating
411     //where to find the applicable terms.
412     //
413     // Additional terms, permissive or non-permissive, may be stated in the
414     //form of a separately written license, or stated as exceptions;
415     //the above requirements apply either way.
416     //
417     // 8. Termination.
418     //
419     // You may not propagate or modify a covered work except as expressly
420     //provided under this License. Any attempt otherwise to propagate or
421     //modify it is void, and will automatically terminate your rights under
422     //this License (including any patent licenses granted under the third
423     //paragraph of section 11).
424     //
425     // However, if you cease all violation of this License, then your
426     //license from a particular copyright holder is reinstated (a)
427     //provisionally, unless and until the copyright holder explicitly and
428     //finally terminates your license, and (b) permanently, if the copyright
429     //holder fails to notify you of the violation by some reasonable means
430     //prior to 60 days after the cessation.
431     //
432     // Moreover, your license from a particular copyright holder is
433     //reinstated permanently if the copyright holder notifies you of the
434     //violation by some reasonable means, this is the first time you have
435     //received notice of violation of this License (for any work) from that
436     //copyright holder, and you cure the violation prior to 30 days after
437     //your receipt of the notice.
438     //
439     // Termination of your rights under this section does not terminate the
440     //licenses of parties who have received copies or rights from you under
441     //this License. If your rights have been terminated and not permanently
442     //reinstated, you do not qualify to receive new licenses for the same
443     //material under section 10.
444     //
445     // 9. Acceptance Not Required for Having Copies.
446     //
447     // You are not required to accept this License in order to receive or
448     //run a copy of the Program. Ancillary propagation of a covered work
449     //occurring solely as a consequence of using peer-to-peer transmission
450     //to receive a copy likewise does not require acceptance. However,
451     //nothing other than this License grants you permission to propagate or
452     //modify any covered work. These actions infringe copyright if you do
453     //not accept this License. Therefore, by modifying or propagating a
454     //covered work, you indicate your acceptance of this License to do so.
455     //
456     // 10. Automatic Licensing of Downstream Recipients.
457     //
458     // Each time you convey a covered work, the recipient automatically
459     //receives a license from the original licensors, to run, modify and
460     //propagate that work, subject to this License. You are not responsible
461     //for enforcing compliance by third parties with this License.
462     //
463     // An "entity transaction" is a transaction transferring control of an
464     //organization, or substantially all assets of one, or subdividing an
465     //organization, or merging organizations. If propagation of a covered
466     //work results from an entity transaction, each party to that
467     //transaction who receives a copy of the work also receives whatever
468     //licenses to the work the party's predecessor in interest had or could
469     //give under the previous paragraph, plus a right to possession of the
470     //Corresponding Source of the work from the predecessor in interest, if
471     //the predecessor has it or can get it with reasonable efforts.
472     //
473     // You may not impose any further restrictions on the exercise of the
474     //rights granted or affirmed under this License. For example, you may
475     //not impose a license fee, royalty, or other charge for exercise of
476     //rights granted under this License, and you may not initiate litigation
477     //(including a cross-claim or counterclaim in a lawsuit) alleging that
478     //any patent claim is infringed by making, using, selling, offering for
479     //sale, or importing the Program or any portion of it.
480     //
481     // 11. Patents.
482     //
483     // A "contributor" is a copyright holder who authorizes use under this
484     //License of the Program or a work on which the Program is based. The
485     //work thus licensed is called the contributor's "contributor version".
486     //
487     // A contributor's "essential patent claims" are all patent claims
488     //owned or controlled by the contributor, whether already acquired or
489     //hereafter acquired, that would be infringed by some manner, permitted
490     //by this License, of making, using, or selling its contributor version,
491     //but do not include claims that would be infringed only as a
492     //consequence of further modification of the contributor version. For
493     //purposes of this definition, "control" includes the right to grant
494     //patent sublicenses in a manner consistent with the requirements of
495     //this License.
496     //
497     // Each contributor grants you a non-exclusive, worldwide, royalty-free
498     //patent license under the contributor's essential patent claims, to
499     //make, use, sell, offer for sale, import and otherwise run, modify and
500     //propagate the contents of its contributor version.
501     //
502     // In the following three paragraphs, a "patent license" is any express
503     //agreement or commitment, however denominated, not to enforce a patent
504     //(such as an express permission to practice a patent or covenant not to
505     //sue for patent infringement). To "grant" such a patent license to a
506     //party means to make such an agreement or commitment not to enforce a
507     //patent against the party.
508     //
509     // If you convey a covered work, knowingly relying on a patent license,
510     //and the Corresponding Source of the work is not available for anyone
511     //to copy, free of charge and under the terms of this License, through a
512     //publicly available network server or other readily accessible means,
513     //then you must either (1) cause the Corresponding Source to be so
514     //available, or (2) arrange to deprive yourself of the benefit of the
515     //patent license for this particular work, or (3) arrange, in a manner
516     //consistent with the requirements of this License, to extend the patent
517     //license to downstream recipients. "Knowingly relying" means you have
518     //actual knowledge that, but for the patent license, your conveying the
519     //covered work in a country, or your recipient's use of the covered work
520     //in a country, would infringe one or more identifiable patents in that
521     //country that you have reason to believe are valid.
522     //
523     // If, pursuant to or in connection with a single transaction or
524     //arrangement, you convey, or propagate by procuring conveyance of, a
525     //covered work, and grant a patent license to some of the parties
526     //receiving the covered work authorizing them to use, propagate, modify
527     //or convey a specific copy of the covered work, then the patent license
528     //you grant is automatically extended to all recipients of the covered
529     //work and works based on it.
530     //
531     // A patent license is "discriminatory" if it does not include within
532     //the scope of its coverage, prohibits the exercise of, or is
533     //conditioned on the non-exercise of one or more of the rights that are
534     //specifically granted under this License. You may not convey a covered
535     //work if you are a party to an arrangement with a third party that is
536     //in the business of distributing software, under which you make payment
537     //to the third party based on the extent of your activity of conveying
538     //the work, and under which the third party grants, to any of the
539     //parties who would receive the covered work from you, a discriminatory
540     //patent license (a) in connection with copies of the covered work
541     //conveyed by you (or copies made from those copies), or (b) primarily
542     //for and in connection with specific products or compilations that
543     //contain the covered work, unless you entered into that arrangement,
544     //or that patent license was granted, prior to 28 March 2007.
545     //
546     // Nothing in this License shall be construed as excluding or limiting
547     //any implied license or other defenses to infringement that may
548     //otherwise be available to you under applicable patent law.
549     //
550     // 12. No Surrender of Others' Freedom.
551     //
552     // If conditions are imposed on you (whether by court order, agreement or
553     //otherwise) that contradict the conditions of this License, they do not
554     //excuse you from the conditions of this License. If you cannot convey a
555     //covered work so as to satisfy simultaneously your obligations under this
556     //License and any other pertinent obligations, then as a consequence you may
557     //not convey it at all. For example, if you agree to terms that obligate you
558     //to collect a royalty for further conveying from those to whom you convey
559     //the Program, the only way you could satisfy both those terms and this
560     //License would be to refrain entirely from conveying the Program.
561     //
562     // 13. Use with the GNU Affero General Public License.
563     //
564     // Notwithstanding any other provision of this License, you have
565     //permission to link or combine any covered work with a work licensed
566     //under version 3 of the GNU Affero General Public License into a single
567     //combined work, and to convey the resulting work. The terms of this
568     //License will continue to apply to the part which is the covered work,
569     //but the special requirements of the GNU Affero General Public License,
570     //section 13, concerning interaction through a network will apply to the
571     //combination as such.
572     //
573     // 14. Revised Versions of this License.
574     //
575     // The Free Software Foundation may publish revised and/or new versions of
576     //the GNU General Public License from time to time. Such new versions will
577     //be similar in spirit to the present version, but may differ in detail to
578     //address new problems or concerns.
579     //
580     // Each version is given a distinguishing version number. If the
581     //Program specifies that a certain numbered version of the GNU General
582     //Public License "or any later version" applies to it, you have the
583     //option of following the terms and conditions either of that numbered
584     //version or of any later version published by the Free Software
585     //Foundation. If the Program does not specify a version number of the
586     //GNU General Public License, you may choose any version ever published
587     //by the Free Software Foundation.
588     //
589     // If the Program specifies that a proxy can decide which future
590     //versions of the GNU General Public License can be used, that proxy's
591     //public statement of acceptance of a version permanently authorizes you
592     //to choose that version for the Program.
593     //
594     // Later license versions may give you additional or different
595     //permissions. However, no additional obligations are imposed on any
596     //author or copyright holder as a result of your choosing to follow a
597     //later version.
598     //
599     // 15. Disclaimer of Warranty.
600     //
601     // THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
602     //APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
603     //HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
604     //OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
605     //THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
606     //PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
607     //IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
608     //ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
609     //
610     // 16. Limitation of Liability.
611     //
612     // IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
613     //WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
614     //THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
615     //GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
616     //USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
617     //DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
618     //PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
619     //EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
620     //SUCH DAMAGES.
621     //
622     // 17. Interpretation of Sections 15 and 16.
623     //
624     // If the disclaimer of warranty and limitation of liability provided
625     //above cannot be given local legal effect according to their terms,
626     //reviewing courts shall apply local law that most closely approximates
627     //an absolute waiver of all civil liability in connection with the
628     //Program, unless a warranty or assumption of liability accompanies a
629     //copy of the Program in return for a fee.
630     //
631     // END OF TERMS AND CONDITIONS
632     //
633     // How to Apply These Terms to Your New Programs
634     //
635     // If you develop a new program, and you want it to be of the greatest
636     //possible use to the public, the best way to achieve this is to make it
637     //free software which everyone can redistribute and change under these terms.
638     //
639     // To do so, attach the following notices to the program. It is safest
640     //to attach them to the start of each source file to most effectively
641     //state the exclusion of warranty; and each file should have at least
642     //the "copyright" line and a pointer to where the full notice is found.
643     //
644     // <one line to give the program's name and a brief idea of what it does.>

657     // You should have received a copy of the GNU General Public License

659     //
660     //Also add information on how to contact you by electronic and paper mail.
661     //
662     // If the program does terminal interaction, make it output a short
663     //notice like this when it starts in an interactive mode:
664     //
665     // <program> Copyright (C) <year> <name of author>

667     // This is free software, and you are welcome to redistribute it

670     //The hypothetical commands `show w' and `show c' should show the appropriate
671     //parts of the General Public License. Of course, your program's commands
672     //might be different; for a GUI interface, you would use an "about box".
673     //
674     // You should also get your employer (if you work as a programmer) or school,
675     //if any, to sign a "copyright disclaimer" for the program, if necessary.

678     //
679     // The GNU General Public License does not permit incorporating your program
680     //into proprietary programs. If your program is a subroutine library, you
681     //may consider it more useful to permit linking proprietary applications with
682     //the library. If this is what you want to do, use the GNU Lesser General
683     //Public License instead of this License. But first, please read

686     //This program, a PHP script, creates thumbnail images for recognized
687     //image files in the current working directory. This program is part of a
688     //3-program suite designed to collectively create a web page directly from
689     //digital camera files (and of course the web page can be customized by
690     //hand-editing after it is automatically generated). The supported process for
691     //creating a web page involves 3 programs (rather than 1) primarily to circumvent
692     //the involuntary process termination that will occur in some shared environments
693     //if a process consumes too much CPU time.
694     //
695     //The 3 programs in the 3-program suite are:
696     //
697     // filenames_canonize.php:
698     // Converts all names of files in a directory to lower-case, and makes
699     // substitutions for any unusual characters.
700     //
701     // thumbnails_make.php (this program):
702     // Creates thumbnails from recognized image types. The thumbnails are
703     // named relative to the original image file with the suffix "_small".
704     // Only 20 files are converted on each invocation of the program, to
705     // avoid the involuntary process termination that typically occurs in
706     // a shared hosting environment when a process uses too much CPU time.
707     // The program should be run repeatedly until it indicates that it has
708     // no more thumbnails to create.
709     //
710     // If any full-sized photos are modified, any corresponding thumbnails
711     // should be deleted and thumbnails_make.php and indexfile_make.php should
712     // be run again.
713     //
714     // indexfile_make.php
715     // Scans a directory and makes an index file ("index2.php") displaying
716     // all the thumbnail images, each of which link to the corresponding
717     // full-sized image. The index file is tailored to Dave Ashley's
718     // needs, but the created file can be edited and most of the content
719     // pasted into an HTML file. To avoid the accidental loss of
720     // information, any existing "index2.php" file is renamed out of the
721     // way.
722     //
723     //This script is designed to be run manually (rather than automatically invoked
724     //as a result of a web page request). It was written in PHP for convenience
725     //simply because DreamHost (the web hosting company Dave Ashley uses) has as part
726     //of its hosting environment PHP with the ImageMagick library compiled in.
727     //
728     //Usually, this script is invoked using "php <path>/indexfile_make.php", but the
729     //method of invocation may vary based on computing platform details.

744     // GNU GENERAL PUBLIC LICENSE
745     // Version 3, 29 June 2007
746     //
747     // Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
748     // Everyone is permitted to copy and distribute verbatim copies
749     // of this license document, but changing it is not allowed.
750     //
751     // Preamble
752     //
753     // The GNU General Public License is a free, copyleft license for
754     // software and other kinds of works.
755     //
756     // The licenses for most software and other practical works are designed
757     // to take away your freedom to share and change the works. By contrast,
758     // the GNU General Public License is intended to guarantee your freedom to
759     // share and change all versions of a program--to make sure it remains free
760     // software for all its users. We, the Free Software Foundation, use the
761     // GNU General Public License for most of our software; it applies also to
762     // any other work released this way by its authors. You can apply it to
763     // your programs, too.
764     //
765     // When we speak of free software, we are referring to freedom, not
766     // price. Our General Public Licenses are designed to make sure that you
767     // have the freedom to distribute copies of free software (and charge for
768     // them if you wish), that you receive source code or can get it if you
769     // want it, that you can change the software or use pieces of it in new
770     // free programs, and that you know you can do these things.
771     //
772     // To protect your rights, we need to prevent others from denying you
773     // these rights or asking you to surrender the rights. Therefore, you have
774     // certain responsibilities if you distribute copies of the software, or if
775     // you modify it: responsibilities to respect the freedom of others.
776     //
777     // For example, if you distribute copies of such a program, whether
778     // gratis or for a fee, you must pass on to the recipients the same
779     // freedoms that you received. You must make sure that they, too, receive
780     // or can get the source code. And you must show them these terms so they
781     // know their rights.
782     //
783     // Developers that use the GNU GPL protect your rights with two steps:
784     // (1) assert copyright on the software, and (2) offer you this License
785     // giving you legal permission to copy, distribute and/or modify it.
786     //
787     // For the developers' and authors' protection, the GPL clearly explains
788     // that there is no warranty for this free software. For both users' and
789     // authors' sake, the GPL requires that modified versions be marked as
790     // changed, so that their problems will not be attributed erroneously to
791     // authors of previous versions.
792     //
793     // Some devices are designed to deny users access to install or run
794     // modified versions of the software inside them, although the manufacturer
795     // can do so. This is fundamentally incompatible with the aim of
796     // protecting users' freedom to change the software. The systematic
797     // pattern of such abuse occurs in the area of products for individuals to
798     // use, which is precisely where it is most unacceptable. Therefore, we
799     // have designed this version of the GPL to prohibit the practice for those
800     // products. If such problems arise substantially in other domains, we
801     // stand ready to extend this provision to those domains in future versions
802     // of the GPL, as needed to protect the freedom of users.
803     //
804     // Finally, every program is threatened constantly by software patents.
805     // States should not allow patents to restrict development and use of
806     // software on general-purpose computers, but in those that do, we wish to
807     // avoid the special danger that patents applied to a free program could
808     // make it effectively proprietary. To prevent this, the GPL assures that
809     // patents cannot be used to render the program non-free.
810     //
811     // The precise terms and conditions for copying, distribution and
812     // modification follow.
813     //
814     // TERMS AND CONDITIONS
815     //
816     // 0. Definitions.
817     //
818     // "This License" refers to version 3 of the GNU General Public License.
819     //
820     // "Copyright" also means copyright-like laws that apply to other kinds of
821     // works, such as semiconductor masks.
822     //
823     // "The Program" refers to any copyrightable work licensed under this
824     // License. Each licensee is addressed as "you". "Licensees" and
825     // "recipients" may be individuals or organizations.
826     //
827     // To "modify" a work means to copy from or adapt all or part of the work
828     // in a fashion requiring copyright permission, other than the making of an
829     // exact copy. The resulting work is called a "modified version" of the
830     // earlier work or a work "based on" the earlier work.
831     //
832     // A "covered work" means either the unmodified Program or a work based
833     // on the Program.
834     //
835     // To "propagate" a work means to do anything with it that, without
836     // permission, would make you directly or secondarily liable for
837     // infringement under applicable copyright law, except executing it on a
838     // computer or modifying a private copy. Propagation includes copying,
839     // distribution (with or without modification), making available to the
840     // public, and in some countries other activities as well.
841     //
842     // To "convey" a work means any kind of propagation that enables other
843     // parties to make or receive copies. Mere interaction with a user through
844     // a computer network, with no transfer of a copy, is not conveying.
845     //
846     // An interactive user interface displays "Appropriate Legal Notices"
847     // to the extent that it includes a convenient and prominently visible
848     // feature that (1) displays an appropriate copyright notice, and (2)
849     // tells the user that there is no warranty for the work (except to the
850     // extent that warranties are provided), that licensees may convey the
851     // work under this License, and how to view a copy of this License. If
852     // the interface presents a list of user commands or options, such as a
853     // menu, a prominent item in the list meets this criterion.
854     //
855     // 1. Source Code.
856     //
857     // The "source code" for a work means the preferred form of the work
858     // for making modifications to it. "Object code" means any non-source
859     // form of a work.
860     //
861     // A "Standard Interface" means an interface that either is an official
862     // standard defined by a recognized standards body, or, in the case of
863     // interfaces specified for a particular programming language, one that
864     // is widely used among developers working in that language.
865     //
866     // The "System Libraries" of an executable work include anything, other
867     // than the work as a whole, that (a) is included in the normal form of
868     // packaging a Major Component, but which is not part of that Major
869     // Component, and (b) serves only to enable use of the work with that
870     // Major Component, or to implement a Standard Interface for which an
871     // implementation is available to the public in source code form. A
872     // "Major Component", in this context, means a major essential component
873     // (kernel, window system, and so on) of the specific operating system
874     // (if any) on which the executable work runs, or a compiler used to
875     // produce the work, or an object code interpreter used to run it.
876     //
877     // The "Corresponding Source" for a work in object code form means all
878     // the source code needed to generate, install, and (for an executable
879     // work) run the object code and to modify the work, including scripts to
880     // control those activities. However, it does not include the work's
881     // System Libraries, or general-purpose tools or generally available free
882     // programs which are used unmodified in performing those activities but
883     // which are not part of the work. For example, Corresponding Source
884     // includes interface definition files associated with source files for
885     // the work, and the source code for shared libraries and dynamically
886     // linked subprograms that the work is specifically designed to require,
887     // such as by intimate data communication or control flow between those
888     // subprograms and other parts of the work.
889     //
890     // The Corresponding Source need not include anything that users
891     // can regenerate automatically from other parts of the Corresponding
892     // Source.
893     //
894     // The Corresponding Source for a work in source code form is that
895     // same work.
896     //
897     // 2. Basic Permissions.
898     //
899     // All rights granted under this License are granted for the term of
900     // copyright on the Program, and are irrevocable provided the stated
901     // conditions are met. This License explicitly affirms your unlimited
902     // permission to run the unmodified Program. The output from running a
903     // covered work is covered by this License only if the output, given its
904     // content, constitutes a covered work. This License acknowledges your
905     // rights of fair use or other equivalent, as provided by copyright law.
906     //
907     // You may make, run and propagate covered works that you do not
908     // convey, without conditions so long as your license otherwise remains
909     // in force. You may convey covered works to others for the sole purpose
910     // of having them make modifications exclusively for you, or provide you
911     // with facilities for running those works, provided that you comply with
912     // the terms of this License in conveying all material for which you do
913     // not control copyright. Those thus making or running the covered works
914     // for you must do so exclusively on your behalf, under your direction
915     // and control, on terms that prohibit them from making any copies of
916     // your copyrighted material outside their relationship with you.
917     //
918     // Conveying under any other circumstances is permitted solely under
919     // the conditions stated below. Sublicensing is not allowed; section 10
920     // makes it unnecessary.
921     //
922     // 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
923     //
924     // No covered work shall be deemed part of an effective technological
925     // measure under any applicable law fulfilling obligations under article
926     // 11 of the WIPO copyright treaty adopted on 20 December 1996, or
927     // similar laws prohibiting or restricting circumvention of such
928     // measures.
929     //
930     // When you convey a covered work, you waive any legal power to forbid
931     // circumvention of technological measures to the extent such circumvention
932     // is effected by exercising rights under this License with respect to
933     // the covered work, and you disclaim any intention to limit operation or
934     // modification of the work as a means of enforcing, against the work's
935     // users, your or third parties' legal rights to forbid circumvention of
936     // technological measures.
937     //
938     // 4. Conveying Verbatim Copies.
939     //
940     // You may convey verbatim copies of the Program's source code as you
941     // receive it, in any medium, provided that you conspicuously and
942     // appropriately publish on each copy an appropriate copyright notice;
943     // keep intact all notices stating that this License and any
944     // non-permissive terms added in accord with section 7 apply to the code;
945     // keep intact all notices of the absence of any warranty; and give all
946     // recipients a copy of this License along with the Program.
947     //
948     // You may charge any price or no price for each copy that you convey,
949     // and you may offer support or warranty protection for a fee.
950     //
951     // 5. Conveying Modified Source Versions.
952     //
953     // You may convey a work based on the Program, or the modifications to
954     // produce it from the Program, in the form of source code under the
955     // terms of section 4, provided that you also meet all of these conditions:
956     //
957     // a) The work must carry prominent notices stating that you modified
958     // it, and giving a relevant date.
959     //
960     // b) The work must carry prominent notices stating that it is
961     // released under this License and any conditions added under section
962     // 7. This requirement modifies the requirement in section 4 to
963     // "keep intact all notices".
964     //
965     // c) You must license the entire work, as a whole, under this
966     // License to anyone who comes into possession of a copy. This
967     // License will therefore apply, along with any applicable section 7
968     // additional terms, to the whole of the work, and all its parts,
969     // regardless of how they are packaged. This License gives no
970     // permission to license the work in any other way, but it does not
971     // invalidate such permission if you have separately received it.
972     //
973     // d) If the work has interactive user interfaces, each must display
974     // Appropriate Legal Notices; however, if the Program has interactive
975     // interfaces that do not display Appropriate Legal Notices, your
976     // work need not make them do so.
977     //
978     // A compilation of a covered work with other separate and independent
979     // works, which are not by their nature extensions of the covered work,
980     // and which are not combined with it such as to form a larger program,
981     // in or on a volume of a storage or distribution medium, is called an
982     // "aggregate" if the compilation and its resulting copyright are not
983     // used to limit the access or legal rights of the compilation's users
984     // beyond what the individual works permit. Inclusion of a covered work
985     // in an aggregate does not cause this License to apply to the other
986     // parts of the aggregate.
987     //
988     // 6. Conveying Non-Source Forms.
989     //
990     // You may convey a covered work in object code form under the terms
991     // of sections 4 and 5, provided that you also convey the
992     // machine-readable Corresponding Source under the terms of this License,
993     // in one of these ways:
994     //
995     // a) Convey the object code in, or embodied in, a physical product
996     // (including a physical distribution medium), accompanied by the
997     // Corresponding Source fixed on a durable physical medium
998     // customarily used for software interchange.
999     //
1000     // b) Convey the object code in, or embodied in, a physical product
1001     // (including a physical distribution medium), accompanied by a
1002     // written offer, valid for at least three years and valid for as
1003     // long as you offer spare parts or customer support for that product
1004     // model, to give anyone who possesses the object code either (1) a
1005     // copy of the Corresponding Source for all the software in the
1006     // product that is covered by this License, on a durable physical
1007     // medium customarily used for software interchange, for a price no
1008     // more than your reasonable cost of physically performing this
1009     // conveying of source, or (2) access to copy the
1010     // Corresponding Source from a network server at no charge.
1011     //
1012     // c) Convey individual copies of the object code with a copy of the
1013     // written offer to provide the Corresponding Source. This
1014     // alternative is allowed only occasionally and noncommercially, and
1015     // only if you received the object code with such an offer, in accord
1016     // with subsection 6b.
1017     //
1018     // d) Convey the object code by offering access from a designated
1019     // place (gratis or for a charge), and offer equivalent access to the
1020     // Corresponding Source in the same way through the same place at no
1021     // further charge. You need not require recipients to copy the
1022     // Corresponding Source along with the object code. If the place to
1023     // copy the object code is a network server, the Corresponding Source
1024     // may be on a different server (operated by you or a third party)
1025     // that supports equivalent copying facilities, provided you maintain
1026     // clear directions next to the object code saying where to find the
1027     // Corresponding Source. Regardless of what server hosts the
1028     // Corresponding Source, you remain obligated to ensure that it is
1029     // available for as long as needed to satisfy these requirements.
1030     //
1031     // e) Convey the object code using peer-to-peer transmission, provided
1032     // you inform other peers where the object code and Corresponding
1033     // Source of the work are being offered to the general public at no
1034     // charge under subsection 6d.
1035     //
1036     // A separable portion of the object code, whose source code is excluded
1037     // from the Corresponding Source as a System Library, need not be
1038     // included in conveying the object code work.
1039     //
1040     // A "User Product" is either (1) a "consumer product", which means any
1041     // tangible personal property which is normally used for personal, family,
1042     // or household purposes, or (2) anything designed or sold for incorporation
1043     // into a dwelling. In determining whether a product is a consumer product,
1044     // doubtful cases shall be resolved in favor of coverage. For a particular
1045     // product received by a particular user, "normally used" refers to a
1046     // typical or common use of that class of product, regardless of the status
1047     // of the particular user or of the way in which the particular user
1048     // actually uses, or expects or is expected to use, the product. A product
1049     // is a consumer product regardless of whether the product has substantial
1050     // commercial, industrial or non-consumer uses, unless such uses represent
1051     // the only significant mode of use of the product.
1052     //
1053     // "Installation Information" for a User Product means any methods,
1054     // procedures, authorization keys, or other information required to install
1055     // and execute modified versions of a covered work in that User Product from
1056     // a modified version of its Corresponding Source. The information must
1057     // suffice to ensure that the continued functioning of the modified object
1058     // code is in no case prevented or interfered with solely because
1059     // modification has been made.
1060     //
1061     // If you convey an object code work under this section in, or with, or
1062     // specifically for use in, a User Product, and the conveying occurs as
1063     // part of a transaction in which the right of possession and use of the
1064     // User Product is transferred to the recipient in perpetuity or for a
1065     // fixed term (regardless of how the transaction is characterized), the
1066     // Corresponding Source conveyed under this section must be accompanied
1067     // by the Installation Information. But this requirement does not apply
1068     // if neither you nor any third party retains the ability to install
1069     // modified object code on the User Product (for example, the work has
1070     // been installed in ROM).
1071     //
1072     // The requirement to provide Installation Information does not include a
1073     // requirement to continue to provide support service, warranty, or updates
1074     // for a work that has been modified or installed by the recipient, or for
1075     // the User Product in which it has been modified or installed. Access to a
1076     // network may be denied when the modification itself materially and
1077     // adversely affects the operation of the network or violates the rules and
1078     // protocols for communication across the network.
1079     //
1080     // Corresponding Source conveyed, and Installation Information provided,
1081     // in accord with this section must be in a format that is publicly
1082     // documented (and with an implementation available to the public in
1083     // source code form), and must require no special password or key for
1084     // unpacking, reading or copying.
1085     //
1086     // 7. Additional Terms.
1087     //
1088     // "Additional permissions" are terms that supplement the terms of this
1089     // License by making exceptions from one or more of its conditions.
1090     // Additional permissions that are applicable to the entire Program shall
1091     // be treated as though they were included in this License, to the extent
1092     // that they are valid under applicable law. If additional permissions
1093     // apply only to part of the Program, that part may be used separately
1094     // under those permissions, but the entire Program remains governed by
1095     // this License without regard to the additional permissions.
1096     //
1097     // When you convey a copy of a covered work, you may at your option
1098     // remove any additional permissions from that copy, or from any part of
1099     // it. (Additional permissions may be written to require their own
1100     // removal in certain cases when you modify the work.) You may place
1101     // additional permissions on material, added by you to a covered work,
1102     // for which you have or can give appropriate copyright permission.
1103     //
1104     // Notwithstanding any other provision of this License, for material you
1105     // add to a covered work, you may (if authorized by the copyright holders of
1106     // that material) supplement the terms of this License with terms:
1107     //
1108     // a) Disclaiming warranty or limiting liability differently from the
1109     // terms of sections 15 and 16 of this License; or
1110     //
1111     // b) Requiring preservation of specified reasonable legal notices or
1112     // author attributions in that material or in the Appropriate Legal
1113     // Notices displayed by works containing it; or
1114     //
1115     // c) Prohibiting misrepresentation of the origin of that material, or
1116     // requiring that modified versions of such material be marked in
1117     // reasonable ways as different from the original version; or
1118     //
1119     // d) Limiting the use for publicity purposes of names of licensors or
1120     // authors of the material; or
1121     //
1122     // e) Declining to grant rights under trademark law for use of some
1123     // trade names, trademarks, or service marks; or
1124     //
1125     // f) Requiring indemnification of licensors and authors of that
1126     // material by anyone who conveys the material (or modified versions of
1127     // it) with contractual assumptions of liability to the recipient, for
1128     // any liability that these contractual assumptions directly impose on
1129     // those licensors and authors.
1130     //
1131     // All other non-permissive additional terms are considered "further
1132     // restrictions" within the meaning of section 10. If the Program as you
1133     // received it, or any part of it, contains a notice stating that it is
1134     // governed by this License along with a term that is a further
1135     // restriction, you may remove that term. If a license document contains
1136     // a further restriction but permits relicensing or conveying under this
1137     // License, you may add to a covered work material governed by the terms
1138     // of that license document, provided that the further restriction does
1139     // not survive such relicensing or conveying.
1140     //
1141     // If you add terms to a covered work in accord with this section, you
1142     // must place, in the relevant source files, a statement of the
1143     // additional terms that apply to those files, or a notice indicating
1144     // where to find the applicable terms.
1145     //
1146     // Additional terms, permissive or non-permissive, may be stated in the
1147     // form of a separately written license, or stated as exceptions;
1148     // the above requirements apply either way.
1149     //
1150     // 8. Termination.
1151     //
1152     // You may not propagate or modify a covered work except as expressly
1153     // provided under this License. Any attempt otherwise to propagate or
1154     // modify it is void, and will automatically terminate your rights under
1155     // this License (including any patent licenses granted under the third
1156     // paragraph of section 11).
1157     //
1158     // However, if you cease all violation of this License, then your
1159     // license from a particular copyright holder is reinstated (a)
1160     // provisionally, unless and until the copyright holder explicitly and
1161     // finally terminates your license, and (b) permanently, if the copyright
1162     // holder fails to notify you of the violation by some reasonable means
1163     // prior to 60 days after the cessation.
1164     //
1165     // Moreover, your license from a particular copyright holder is
1166     // reinstated permanently if the copyright holder notifies you of the
1167     // violation by some reasonable means, this is the first time you have
1168     // received notice of violation of this License (for any work) from that
1169     // copyright holder, and you cure the violation prior to 30 days after
1170     // your receipt of the notice.
1171     //
1172     // Termination of your rights under this section does not terminate the
1173     // licenses of parties who have received copies or rights from you under
1174     // this License. If your rights have been terminated and not permanently
1175     // reinstated, you do not qualify to receive new licenses for the same
1176     // material under section 10.
1177     //
1178     // 9. Acceptance Not Required for Having Copies.
1179     //
1180     // You are not required to accept this License in order to receive or
1181     // run a copy of the Program. Ancillary propagation of a covered work
1182     // occurring solely as a consequence of using peer-to-peer transmission
1183     // to receive a copy likewise does not require acceptance. However,
1184     // nothing other than this License grants you permission to propagate or
1185     // modify any covered work. These actions infringe copyright if you do
1186     // not accept this License. Therefore, by modifying or propagating a
1187     // covered work, you indicate your acceptance of this License to do so.
1188     //
1189     // 10. Automatic Licensing of Downstream Recipients.
1190     //
1191     // Each time you convey a covered work, the recipient automatically
1192     // receives a license from the original licensors, to run, modify and
1193     // propagate that work, subject to this License. You are not responsible
1194     // for enforcing compliance by third parties with this License.
1195     //
1196     // An "entity transaction" is a transaction transferring control of an
1197     // organization, or substantially all assets of one, or subdividing an
1198     // organization, or merging organizations. If propagation of a covered
1199     // work results from an entity transaction, each party to that
1200     // transaction who receives a copy of the work also receives whatever
1201     // licenses to the work the party's predecessor in interest had or could
1202     // give under the previous paragraph, plus a right to possession of the
1203     // Corresponding Source of the work from the predecessor in interest, if
1204     // the predecessor has it or can get it with reasonable efforts.
1205     //
1206     // You may not impose any further restrictions on the exercise of the
1207     // rights granted or affirmed under this License. For example, you may
1208     // not impose a license fee, royalty, or other charge for exercise of
1209     // rights granted under this License, and you may not initiate litigation
1210     // (including a cross-claim or counterclaim in a lawsuit) alleging that
1211     // any patent claim is infringed by making, using, selling, offering for
1212     // sale, or importing the Program or any portion of it.
1213     //
1214     // 11. Patents.
1215     //
1216     // A "contributor" is a copyright holder who authorizes use under this
1217     // License of the Program or a work on which the Program is based. The
1218     // work thus licensed is called the contributor's "contributor version".
1219     //
1220     // A contributor's "essential patent claims" are all patent claims
1221     // owned or controlled by the contributor, whether already acquired or
1222     // hereafter acquired, that would be infringed by some manner, permitted
1223     // by this License, of making, using, or selling its contributor version,
1224     // but do not include claims that would be infringed only as a
1225     // consequence of further modification of the contributor version. For
1226     // purposes of this definition, "control" includes the right to grant
1227     // patent sublicenses in a manner consistent with the requirements of
1228     // this License.
1229     //
1230     // Each contributor grants you a non-exclusive, worldwide, royalty-free
1231     // patent license under the contributor's essential patent claims, to
1232     // make, use, sell, offer for sale, import and otherwise run, modify and
1233     // propagate the contents of its contributor version.
1234     //
1235     // In the following three paragraphs, a "patent license" is any express
1236     // agreement or commitment, however denominated, not to enforce a patent
1237     // (such as an express permission to practice a patent or covenant not to
1238     // sue for patent infringement). To "grant" such a patent license to a
1239     // party means to make such an agreement or commitment not to enforce a
1240     // patent against the party.
1241     //
1242     // If you convey a covered work, knowingly relying on a patent license,
1243     // and the Corresponding Source of the work is not available for anyone
1244     // to copy, free of charge and under the terms of this License, through a
1245     // publicly available network server or other readily accessible means,
1246     // then you must either (1) cause the Corresponding Source to be so
1247     // available, or (2) arrange to deprive yourself of the benefit of the
1248     // patent license for this particular work, or (3) arrange, in a manner
1249     // consistent with the requirements of this License, to extend the patent
1250     // license to downstream recipients. "Knowingly relying" means you have
1251     // actual knowledge that, but for the patent license, your conveying the
1252     // covered work in a country, or your recipient's use of the covered work
1253     // in a country, would infringe one or more identifiable patents in that
1254     // country that you have reason to believe are valid.
1255     //
1256     // If, pursuant to or in connection with a single transaction or
1257     // arrangement, you convey, or propagate by procuring conveyance of, a
1258     // covered work, and grant a patent license to some of the parties
1259     // receiving the covered work authorizing them to use, propagate, modify
1260     // or convey a specific copy of the covered work, then the patent license
1261     // you grant is automatically extended to all recipients of the covered
1262     // work and works based on it.
1263     //
1264     // A patent license is "discriminatory" if it does not include within
1265     // the scope of its coverage, prohibits the exercise of, or is
1266     // conditioned on the non-exercise of one or more of the rights that are
1267     // specifically granted under this License. You may not convey a covered
1268     // work if you are a party to an arrangement with a third party that is
1269     // in the business of distributing software, under which you make payment
1270     // to the third party based on the extent of your activity of conveying
1271     // the work, and under which the third party grants, to any of the

1317     // version or of any later version published by the Free Software
1318     // Foundation. If the Program does not specify a version number of the

1320     // by the Free Software Foundation.

1322     // If the Program specifies that a proxy can decide which future
1323     // versions of the GNU General Public License can be used, that proxy's
1324     // public statement of acceptance of a version permanently authorizes you
1325     // to choose that version for the Program.
