2 //Copyright 2016 David T. Ashley
3 //-------------------------------------------------------------------------------------------------
4 //This source code and any program in which it is compiled/used is provided under the GNU GENERAL
5 //PUBLIC LICENSE, Version 3, full license text below.
6 //-------------------------------------------------------------------------------------------------
7 // GNU GENERAL PUBLIC LICENSE
8 // Version 3, 29 June 2007
9 //
10 // Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
11 // Everyone is permitted to copy and distribute verbatim copies
12 // of this license document, but changing it is not allowed.
13 //
14 // Preamble
15 //
16 // The GNU General Public License is a free, copyleft license for
17 //software and other kinds of works.
18 //
19 // The licenses for most software and other practical works are designed
20 //to take away your freedom to share and change the works. By contrast,
21 //the GNU General Public License is intended to guarantee your freedom to
22 //share and change all versions of a program--to make sure it remains free
23 //software for all its users. We, the Free Software Foundation, use the
24 //GNU General Public License for most of our software; it applies also to
25 //any other work released this way by its authors. You can apply it to
26 //your programs, too.
27 //
28 // When we speak of free software, we are referring to freedom, not
29 //price. Our General Public Licenses are designed to make sure that you
30 //have the freedom to distribute copies of free software (and charge for
31 //them if you wish), that you receive source code or can get it if you
32 //want it, that you can change the software or use pieces of it in new
33 //free programs, and that you know you can do these things.
34 //
35 // To protect your rights, we need to prevent others from denying you
36 //these rights or asking you to surrender the rights. Therefore, you have
37 //certain responsibilities if you distribute copies of the software, or if
38 //you modify it: responsibilities to respect the freedom of others.
39 //
40 // For example, if you distribute copies of such a program, whether
41 //gratis or for a fee, you must pass on to the recipients the same
42 //freedoms that you received. You must make sure that they, too, receive
43 //or can get the source code. And you must show them these terms so they
44 //know their rights.
45 //
46 // Developers that use the GNU GPL protect your rights with two steps:
47 //(1) assert copyright on the software, and (2) offer you this License
48 //giving you legal permission to copy, distribute and/or modify it.
49 //
50 // For the developers' and authors' protection, the GPL clearly explains
51 //that there is no warranty for this free software. For both users' and
52 //authors' sake, the GPL requires that modified versions be marked as
53 //changed, so that their problems will not be attributed erroneously to
54 //authors of previous versions.
55 //
56 // Some devices are designed to deny users access to install or run
57 //modified versions of the software inside them, although the manufacturer
58 //can do so. This is fundamentally incompatible with the aim of
59 //protecting users' freedom to change the software. The systematic
60 //pattern of such abuse occurs in the area of products for individuals to
61 //use, which is precisely where it is most unacceptable. Therefore, we
62 //have designed this version of the GPL to prohibit the practice for those
63 //products. If such problems arise substantially in other domains, we
64 //stand ready to extend this provision to those domains in future versions
65 //of the GPL, as needed to protect the freedom of users.
66 //
67 // Finally, every program is threatened constantly by software patents.
68 //States should not allow patents to restrict development and use of
69 //software on general-purpose computers, but in those that do, we wish to
70 //avoid the special danger that patents applied to a free program could
71 //make it effectively proprietary. To prevent this, the GPL assures that
72 //patents cannot be used to render the program non-free.
73 //
74 // The precise terms and conditions for copying, distribution and
75 //modification follow.
76 //
77 // TERMS AND CONDITIONS
78 //
79 // 0. Definitions.
80 //
81 // "This License" refers to version 3 of the GNU General Public License.
82 //
83 // "Copyright" also means copyright-like laws that apply to other kinds of
84 //works, such as semiconductor masks.
85 //
86 // "The Program" refers to any copyrightable work licensed under this
87 //License. Each licensee is addressed as "you". "Licensees" and
88 //"recipients" may be individuals or organizations.
89 //
90 // To "modify" a work means to copy from or adapt all or part of the work
91 //in a fashion requiring copyright permission, other than the making of an
92 //exact copy. The resulting work is called a "modified version" of the
93 //earlier work or a work "based on" the earlier work.
94 //
95 // A "covered work" means either the unmodified Program or a work based
96 //on the Program.
97 //
98 // To "propagate" a work means to do anything with it that, without
99 //permission, would make you directly or secondarily liable for
100 //infringement under applicable copyright law, except executing it on a
101 //computer or modifying a private copy. Propagation includes copying,
102 //distribution (with or without modification), making available to the
103 //public, and in some countries other activities as well.
104 //
105 // To "convey" a work means any kind of propagation that enables other
106 //parties to make or receive copies. Mere interaction with a user through
107 //a computer network, with no transfer of a copy, is not conveying.
108 //
109 // An interactive user interface displays "Appropriate Legal Notices"
110 //to the extent that it includes a convenient and prominently visible
111 //feature that (1) displays an appropriate copyright notice, and (2)
112 //tells the user that there is no warranty for the work (except to the
113 //extent that warranties are provided), that licensees may convey the
114 //work under this License, and how to view a copy of this License. If
115 //the interface presents a list of user commands or options, such as a
116 //menu, a prominent item in the list meets this criterion.
117 //
118 // 1. Source Code.
119 //
120 // The "source code" for a work means the preferred form of the work
121 //for making modifications to it. "Object code" means any non-source
122 //form of a work.
123 //
124 // A "Standard Interface" means an interface that either is an official
125 //standard defined by a recognized standards body, or, in the case of
126 //interfaces specified for a particular programming language, one that
127 //is widely used among developers working in that language.
128 //
129 // The "System Libraries" of an executable work include anything, other
130 //than the work as a whole, that (a) is included in the normal form of
131 //packaging a Major Component, but which is not part of that Major
132 //Component, and (b) serves only to enable use of the work with that
133 //Major Component, or to implement a Standard Interface for which an
134 //implementation is available to the public in source code form. A
135 //"Major Component", in this context, means a major essential component
136 //(kernel, window system, and so on) of the specific operating system
137 //(if any) on which the executable work runs, or a compiler used to
138 //produce the work, or an object code interpreter used to run it.
139 //
140 // The "Corresponding Source" for a work in object code form means all
141 //the source code needed to generate, install, and (for an executable
142 //work) run the object code and to modify the work, including scripts to
143 //control those activities. However, it does not include the work's
144 //System Libraries, or general-purpose tools or generally available free
145 //programs which are used unmodified in performing those activities but
146 //which are not part of the work. For example, Corresponding Source
147 //includes interface definition files associated with source files for
148 //the work, and the source code for shared libraries and dynamically
149 //linked subprograms that the work is specifically designed to require,
150 //such as by intimate data communication or control flow between those
151 //subprograms and other parts of the work.
152 //
153 // The Corresponding Source need not include anything that users
154 //can regenerate automatically from other parts of the Corresponding
155 //Source.
156 //
157 // The Corresponding Source for a work in source code form is that
158 //same work.
159 //
160 // 2. Basic Permissions.
161 //
162 // All rights granted under this License are granted for the term of
163 //copyright on the Program, and are irrevocable provided the stated
164 //conditions are met. This License explicitly affirms your unlimited
165 //permission to run the unmodified Program. The output from running a
166 //covered work is covered by this License only if the output, given its
167 //content, constitutes a covered work. This License acknowledges your
168 //rights of fair use or other equivalent, as provided by copyright law.
169 //
170 // You may make, run and propagate covered works that you do not
171 //convey, without conditions so long as your license otherwise remains
172 //in force. You may convey covered works to others for the sole purpose
173 //of having them make modifications exclusively for you, or provide you
174 //with facilities for running those works, provided that you comply with
175 //the terms of this License in conveying all material for which you do
176 //not control copyright. Those thus making or running the covered works
177 //for you must do so exclusively on your behalf, under your direction
178 //and control, on terms that prohibit them from making any copies of
179 //your copyrighted material outside their relationship with you.
180 //
181 // Conveying under any other circumstances is permitted solely under
182 //the conditions stated below. Sublicensing is not allowed; section 10
183 //makes it unnecessary.
184 //
185 // 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
186 //
187 // No covered work shall be deemed part of an effective technological
188 //measure under any applicable law fulfilling obligations under article
189 //11 of the WIPO copyright treaty adopted on 20 December 1996, or
190 //similar laws prohibiting or restricting circumvention of such
191 //measures.
192 //
193 // When you convey a covered work, you waive any legal power to forbid
194 //circumvention of technological measures to the extent such circumvention
195 //is effected by exercising rights under this License with respect to
196 //the covered work, and you disclaim any intention to limit operation or
197 //modification of the work as a means of enforcing, against the work's
198 //users, your or third parties' legal rights to forbid circumvention of
199 //technological measures.
200 //
201 // 4. Conveying Verbatim Copies.
202 //
203 // You may convey verbatim copies of the Program's source code as you
204 //receive it, in any medium, provided that you conspicuously and
205 //appropriately publish on each copy an appropriate copyright notice;
206 //keep intact all notices stating that this License and any
207 //non-permissive terms added in accord with section 7 apply to the code;
208 //keep intact all notices of the absence of any warranty; and give all
209 //recipients a copy of this License along with the Program.
210 //
211 // You may charge any price or no price for each copy that you convey,
212 //and you may offer support or warranty protection for a fee.
213 //
214 // 5. Conveying Modified Source Versions.
215 //
216 // You may convey a work based on the Program, or the modifications to
217 //produce it from the Program, in the form of source code under the
218 //terms of section 4, provided that you also meet all of these conditions:
219 //
220 // a) The work must carry prominent notices stating that you modified
221 // it, and giving a relevant date.
222 //
223 // b) The work must carry prominent notices stating that it is
224 // released under this License and any conditions added under section
225 // 7. This requirement modifies the requirement in section 4 to
226 // "keep intact all notices".
227 //
228 // c) You must license the entire work, as a whole, under this
229 // License to anyone who comes into possession of a copy. This
230 // License will therefore apply, along with any applicable section 7
231 // additional terms, to the whole of the work, and all its parts,
232 // regardless of how they are packaged. This License gives no
233 // permission to license the work in any other way, but it does not
234 // invalidate such permission if you have separately received it.
235 //
236 // d) If the work has interactive user interfaces, each must display
237 // Appropriate Legal Notices; however, if the Program has interactive
238 // interfaces that do not display Appropriate Legal Notices, your
239 // work need not make them do so.
240 //
241 // A compilation of a covered work with other separate and independent
242 //works, which are not by their nature extensions of the covered work,
243 //and which are not combined with it such as to form a larger program,
244 //in or on a volume of a storage or distribution medium, is called an
245 //"aggregate" if the compilation and its resulting copyright are not
246 //used to limit the access or legal rights of the compilation's users
247 //beyond what the individual works permit. Inclusion of a covered work
248 //in an aggregate does not cause this License to apply to the other
249 //parts of the aggregate.
250 //
251 // 6. Conveying Non-Source Forms.
252 //
253 // You may convey a covered work in object code form under the terms
254 //of sections 4 and 5, provided that you also convey the
255 //machine-readable Corresponding Source under the terms of this License,
256 //in one of these ways:
257 //
258 // a) Convey the object code in, or embodied in, a physical product
259 // (including a physical distribution medium), accompanied by the
260 // Corresponding Source fixed on a durable physical medium
261 // customarily used for software interchange.
262 //
263 // b) Convey the object code in, or embodied in, a physical product
264 // (including a physical distribution medium), accompanied by a
265 // written offer, valid for at least three years and valid for as
266 // long as you offer spare parts or customer support for that product
267 // model, to give anyone who possesses the object code either (1) a
268 // copy of the Corresponding Source for all the software in the
269 // product that is covered by this License, on a durable physical
270 // medium customarily used for software interchange, for a price no
271 // more than your reasonable cost of physically performing this
272 // conveying of source, or (2) access to copy the
273 // Corresponding Source from a network server at no charge.
274 //
275 // c) Convey individual copies of the object code with a copy of the
276 // written offer to provide the Corresponding Source. This
277 // alternative is allowed only occasionally and noncommercially, and
278 // only if you received the object code with such an offer, in accord
279 // with subsection 6b.
280 //
281 // d) Convey the object code by offering access from a designated
282 // place (gratis or for a charge), and offer equivalent access to the
283 // Corresponding Source in the same way through the same place at no
284 // further charge. You need not require recipients to copy the
285 // Corresponding Source along with the object code. If the place to
286 // copy the object code is a network server, the Corresponding Source
287 // may be on a different server (operated by you or a third party)
288 // that supports equivalent copying facilities, provided you maintain
289 // clear directions next to the object code saying where to find the
290 // Corresponding Source. Regardless of what server hosts the
291 // Corresponding Source, you remain obligated to ensure that it is
292 // available for as long as needed to satisfy these requirements.
293 //
294 // e) Convey the object code using peer-to-peer transmission, provided
295 // you inform other peers where the object code and Corresponding
296 // Source of the work are being offered to the general public at no
297 // charge under subsection 6d.
298 //
299 // A separable portion of the object code, whose source code is excluded
300 //from the Corresponding Source as a System Library, need not be
301 //included in conveying the object code work.
302 //
303 // A "User Product" is either (1) a "consumer product", which means any
304 //tangible personal property which is normally used for personal, family,
305 //or household purposes, or (2) anything designed or sold for incorporation
306 //into a dwelling. In determining whether a product is a consumer product,
307 //doubtful cases shall be resolved in favor of coverage. For a particular
308 //product received by a particular user, "normally used" refers to a
309 //typical or common use of that class of product, regardless of the status
310 //of the particular user or of the way in which the particular user
311 //actually uses, or expects or is expected to use, the product. A product
312 //is a consumer product regardless of whether the product has substantial
313 //commercial, industrial or non-consumer uses, unless such uses represent
314 //the only significant mode of use of the product.
315 //
316 // "Installation Information" for a User Product means any methods,
317 //procedures, authorization keys, or other information required to install
318 //and execute modified versions of a covered work in that User Product from
319 //a modified version of its Corresponding Source. The information must
320 //suffice to ensure that the continued functioning of the modified object
321 //code is in no case prevented or interfered with solely because
322 //modification has been made.
323 //
324 // If you convey an object code work under this section in, or with, or
325 //specifically for use in, a User Product, and the conveying occurs as
326 //part of a transaction in which the right of possession and use of the
327 //User Product is transferred to the recipient in perpetuity or for a
328 //fixed term (regardless of how the transaction is characterized), the
329 //Corresponding Source conveyed under this section must be accompanied
330 //by the Installation Information. But this requirement does not apply
331 //if neither you nor any third party retains the ability to install
332 //modified object code on the User Product (for example, the work has
333 //been installed in ROM).
334 //
335 // The requirement to provide Installation Information does not include a
336 //requirement to continue to provide support service, warranty, or updates
337 //for a work that has been modified or installed by the recipient, or for
338 //the User Product in which it has been modified or installed. Access to a
339 //network may be denied when the modification itself materially and
340 //adversely affects the operation of the network or violates the rules and
341 //protocols for communication across the network.
342 //
343 // Corresponding Source conveyed, and Installation Information provided,
344 //in accord with this section must be in a format that is publicly
345 //documented (and with an implementation available to the public in
346 //source code form), and must require no special password or key for
347 //unpacking, reading or copying.
348 //
349 // 7. Additional Terms.
350 //
351 // "Additional permissions" are terms that supplement the terms of this
352 //License by making exceptions from one or more of its conditions.
353 //Additional permissions that are applicable to the entire Program shall
354 //be treated as though they were included in this License, to the extent
355 //that they are valid under applicable law. If additional permissions
356 //apply only to part of the Program, that part may be used separately
357 //under those permissions, but the entire Program remains governed by
358 //this License without regard to the additional permissions.
359 //
360 // When you convey a copy of a covered work, you may at your option
361 //remove any additional permissions from that copy, or from any part of
362 //it. (Additional permissions may be written to require their own
363 //removal in certain cases when you modify the work.) You may place
364 //additional permissions on material, added by you to a covered work,
365 //for which you have or can give appropriate copyright permission.
366 //
367 // Notwithstanding any other provision of this License, for material you
368 //add to a covered work, you may (if authorized by the copyright holders of
369 //that material) supplement the terms of this License with terms:
370 //
371 // a) Disclaiming warranty or limiting liability differently from the
372 // terms of sections 15 and 16 of this License; or
373 //
374 // b) Requiring preservation of specified reasonable legal notices or
375 // author attributions in that material or in the Appropriate Legal
376 // Notices displayed by works containing it; or
377 //
378 // c) Prohibiting misrepresentation of the origin of that material, or
379 // requiring that modified versions of such material be marked in
380 // reasonable ways as different from the original version; or
381 //
382 // d) Limiting the use for publicity purposes of names of licensors or
383 // authors of the material; or
384 //
385 // e) Declining to grant rights under trademark law for use of some
386 // trade names, trademarks, or service marks; or
387 //
388 // f) Requiring indemnification of licensors and authors of that
389 // material by anyone who conveys the material (or modified versions of
390 // it) with contractual assumptions of liability to the recipient, for
391 // any liability that these contractual assumptions directly impose on
392 // those licensors and authors.
393 //
394 // All other non-permissive additional terms are considered "further
395 //restrictions" within the meaning of section 10. If the Program as you
396 //received it, or any part of it, contains a notice stating that it is
397 //governed by this License along with a term that is a further
398 //restriction, you may remove that term. If a license document contains
399 //a further restriction but permits relicensing or conveying under this
400 //License, you may add to a covered work material governed by the terms
401 //of that license document, provided that the further restriction does
402 //not survive such relicensing or conveying.
403 //
404 // If you add terms to a covered work in accord with this section, you
405 //must place, in the relevant source files, a statement of the
406 //additional terms that apply to those files, or a notice indicating
407 //where to find the applicable terms.
408 //
409 // Additional terms, permissive or non-permissive, may be stated in the
410 //form of a separately written license, or stated as exceptions;
411 //the above requirements apply either way.
412 //
413 // 8. Termination.
414 //
415 // You may not propagate or modify a covered work except as expressly
416 //provided under this License. Any attempt otherwise to propagate or
417 //modify it is void, and will automatically terminate your rights under
418 //this License (including any patent licenses granted under the third
419 //paragraph of section 11).
420 //
421 // However, if you cease all violation of this License, then your
422 //license from a particular copyright holder is reinstated (a)
423 //provisionally, unless and until the copyright holder explicitly and
424 //finally terminates your license, and (b) permanently, if the copyright
425 //holder fails to notify you of the violation by some reasonable means
426 //prior to 60 days after the cessation.
427 //
428 // Moreover, your license from a particular copyright holder is
429 //reinstated permanently if the copyright holder notifies you of the
430 //violation by some reasonable means, this is the first time you have
431 //received notice of violation of this License (for any work) from that
432 //copyright holder, and you cure the violation prior to 30 days after
433 //your receipt of the notice.
434 //
435 // Termination of your rights under this section does not terminate the
436 //licenses of parties who have received copies or rights from you under
437 //this License. If your rights have been terminated and not permanently
438 //reinstated, you do not qualify to receive new licenses for the same
439 //material under section 10.
440 //
441 // 9. Acceptance Not Required for Having Copies.
442 //
443 // You are not required to accept this License in order to receive or
444 //run a copy of the Program. Ancillary propagation of a covered work
445 //occurring solely as a consequence of using peer-to-peer transmission
446 //to receive a copy likewise does not require acceptance. However,
447 //nothing other than this License grants you permission to propagate or
448 //modify any covered work. These actions infringe copyright if you do
449 //not accept this License. Therefore, by modifying or propagating a
450 //covered work, you indicate your acceptance of this License to do so.
451 //
452 // 10. Automatic Licensing of Downstream Recipients.
453 //
454 // Each time you convey a covered work, the recipient automatically
455 //receives a license from the original licensors, to run, modify and
456 //propagate that work, subject to this License. You are not responsible
457 //for enforcing compliance by third parties with this License.
458 //
459 // An "entity transaction" is a transaction transferring control of an
460 //organization, or substantially all assets of one, or subdividing an
461 //organization, or merging organizations. If propagation of a covered
462 //work results from an entity transaction, each party to that
463 //transaction who receives a copy of the work also receives whatever
464 //licenses to the work the party's predecessor in interest had or could
465 //give under the previous paragraph, plus a right to possession of the
466 //Corresponding Source of the work from the predecessor in interest, if
467 //the predecessor has it or can get it with reasonable efforts.
468 //
469 // You may not impose any further restrictions on the exercise of the
470 //rights granted or affirmed under this License. For example, you may
471 //not impose a license fee, royalty, or other charge for exercise of
472 //rights granted under this License, and you may not initiate litigation
473 //(including a cross-claim or counterclaim in a lawsuit) alleging that
474 //any patent claim is infringed by making, using, selling, offering for
475 //sale, or importing the Program or any portion of it.
476 //
477 // 11. Patents.
478 //
479 // A "contributor" is a copyright holder who authorizes use under this
480 //License of the Program or a work on which the Program is based. The
481 //work thus licensed is called the contributor's "contributor version".
482 //
483 // A contributor's "essential patent claims" are all patent claims
484 //owned or controlled by the contributor, whether already acquired or
485 //hereafter acquired, that would be infringed by some manner, permitted
486 //by this License, of making, using, or selling its contributor version,
487 //but do not include claims that would be infringed only as a
488 //consequence of further modification of the contributor version. For
489 //purposes of this definition, "control" includes the right to grant
490 //patent sublicenses in a manner consistent with the requirements of
491 //this License.
492 //
493 // Each contributor grants you a non-exclusive, worldwide, royalty-free
494 //patent license under the contributor's essential patent claims, to
495 //make, use, sell, offer for sale, import and otherwise run, modify and
496 //propagate the contents of its contributor version.
497 //
498 // In the following three paragraphs, a "patent license" is any express
499 //agreement or commitment, however denominated, not to enforce a patent
500 //(such as an express permission to practice a patent or covenant not to
501 //sue for patent infringement). To "grant" such a patent license to a
502 //party means to make such an agreement or commitment not to enforce a
503 //patent against the party.
504 //
505 // If you convey a covered work, knowingly relying on a patent license,
506 //and the Corresponding Source of the work is not available for anyone
507 //to copy, free of charge and under the terms of this License, through a
508 //publicly available network server or other readily accessible means,
509 //then you must either (1) cause the Corresponding Source to be so
510 //available, or (2) arrange to deprive yourself of the benefit of the
511 //patent license for this particular work, or (3) arrange, in a manner
512 //consistent with the requirements of this License, to extend the patent
513 //license to downstream recipients. "Knowingly relying" means you have
514 //actual knowledge that, but for the patent license, your conveying the
515 //covered work in a country, or your recipient's use of the covered work
516 //in a country, would infringe one or more identifiable patents in that
517 //country that you have reason to believe are valid.
518 //
519 // If, pursuant to or in connection with a single transaction or
520 //arrangement, you convey, or propagate by procuring conveyance of, a
521 //covered work, and grant a patent license to some of the parties
522 //receiving the covered work authorizing them to use, propagate, modify
523 //or convey a specific copy of the covered work, then the patent license
524 //you grant is automatically extended to all recipients of the covered
525 //work and works based on it.
526 //
527 // A patent license is "discriminatory" if it does not include within
528 //the scope of its coverage, prohibits the exercise of, or is
529 //conditioned on the non-exercise of one or more of the rights that are
530 //specifically granted under this License. You may not convey a covered
531 //work if you are a party to an arrangement with a third party that is
532 //in the business of distributing software, under which you make payment
533 //to the third party based on the extent of your activity of conveying
534 //the work, and under which the third party grants, to any of the
535 //parties who would receive the covered work from you, a discriminatory
536 //patent license (a) in connection with copies of the covered work
537 //conveyed by you (or copies made from those copies), or (b) primarily
538 //for and in connection with specific products or compilations that
539 //contain the covered work, unless you entered into that arrangement,
540 //or that patent license was granted, prior to 28 March 2007.
541 //
542 // Nothing in this License shall be construed as excluding or limiting
543 //any implied license or other defenses to infringement that may
544 //otherwise be available to you under applicable patent law.
545 //
546 // 12. No Surrender of Others' Freedom.
547 //
548 // If conditions are imposed on you (whether by court order, agreement or
549 //otherwise) that contradict the conditions of this License, they do not
550 //excuse you from the conditions of this License. If you cannot convey a
551 //covered work so as to satisfy simultaneously your obligations under this
552 //License and any other pertinent obligations, then as a consequence you may
553 //not convey it at all. For example, if you agree to terms that obligate you
554 //to collect a royalty for further conveying from those to whom you convey
555 //the Program, the only way you could satisfy both those terms and this
556 //License would be to refrain entirely from conveying the Program.
557 //
558 // 13. Use with the GNU Affero General Public License.
559 //
560 // Notwithstanding any other provision of this License, you have
561 //permission to link or combine any covered work with a work licensed
562 //under version 3 of the GNU Affero General Public License into a single
563 //combined work, and to convey the resulting work. The terms of this
564 //License will continue to apply to the part which is the covered work,
565 //but the special requirements of the GNU Affero General Public License,
566 //section 13, concerning interaction through a network will apply to the
567 //combination as such.
568 //
569 // 14. Revised Versions of this License.
570 //
571 // The Free Software Foundation may publish revised and/or new versions of
572 //the GNU General Public License from time to time. Such new versions will
573 //be similar in spirit to the present version, but may differ in detail to
574 //address new problems or concerns.
575 //
576 // Each version is given a distinguishing version number. If the
577 //Program specifies that a certain numbered version of the GNU General
578 //Public License "or any later version" applies to it, you have the
579 //option of following the terms and conditions either of that numbered
580 //version or of any later version published by the Free Software
581 //Foundation. If the Program does not specify a version number of the
582 //GNU General Public License, you may choose any version ever published
583 //by the Free Software Foundation.
584 //
585 // If the Program specifies that a proxy can decide which future
586 //versions of the GNU General Public License can be used, that proxy's
587 //public statement of acceptance of a version permanently authorizes you
588 //to choose that version for the Program.
589 //
590 // Later license versions may give you additional or different
591 //permissions. However, no additional obligations are imposed on any
592 //author or copyright holder as a result of your choosing to follow a
593 //later version.
594 //
595 // 15. Disclaimer of Warranty.
596 //
597 // THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
598 //APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
599 //HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
600 //OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
601 //THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
602 //PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
603 //IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
604 //ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
605 //
606 // 16. Limitation of Liability.
607 //
608 // IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
609 //WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
610 //THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
611 //GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
612 //USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
613 //DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
614 //PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
615 //EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
616 //SUCH DAMAGES.
617 //
618 // 17. Interpretation of Sections 15 and 16.
619 //
620 // If the disclaimer of warranty and limitation of liability provided
621 //above cannot be given local legal effect according to their terms,
622 //reviewing courts shall apply local law that most closely approximates
623 //an absolute waiver of all civil liability in connection with the
624 //Program, unless a warranty or assumption of liability accompanies a
625 //copy of the Program in return for a fee.
626 //
627 // END OF TERMS AND CONDITIONS
628 //
629 // How to Apply These Terms to Your New Programs
630 //
631 // If you develop a new program, and you want it to be of the greatest
632 //possible use to the public, the best way to achieve this is to make it
633 //free software which everyone can redistribute and change under these terms.
634 //
635 // To do so, attach the following notices to the program. It is safest
636 //to attach them to the start of each source file to most effectively
637 //state the exclusion of warranty; and each file should have at least
638 //the "copyright" line and a pointer to where the full notice is found.
639 //
640 // <one line to give the program's name and a brief idea of what it does.>
641 // Copyright (C) <year> <name of author>
642 //
643 // This program is free software: you can redistribute it and/or modify
644 // it under the terms of the GNU General Public License as published by

646 // (at your option) any later version.
647 //
648 // This program is distributed in the hope that it will be useful,
649 // but WITHOUT ANY WARRANTY; without even the implied warranty of

652 //
653 // You should have received a copy of the GNU General Public License
654 // along with this program. If not, see <http://www.gnu.org/licenses/>.
655 //
656 //Also add information on how to contact you by electronic and paper mail.
657 //
658 // If the program does terminal interaction, make it output a short
659 //notice like this when it starts in an interactive mode:
660 //
661 // <program> Copyright (C) <year> <name of author>
662 // This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
663 // This is free software, and you are welcome to redistribute it
664 // under certain conditions; type `show c' for details.
665 //
666 //The hypothetical commands `show w' and `show c' should show the appropriate
667 //parts of the General Public License. Of course, your program's commands
668 //might be different; for a GUI interface, you would use an "about box".
669 //
670 // You should also get your employer (if you work as a programmer) or school,
671 //if any, to sign a "copyright disclaimer" for the program, if necessary.
672 //For more information on this, and how to apply and follow the GNU GPL, see

682 //This program, a PHP script, modifies all filenames in a directory to a canonical
683 //form (no upper-case letters or unusual characters). This program is part of a
684 //3-program suite designed to collectively create a web page directly from
685 //digital camera files (and of course the web page can be customized by
686 //hand-editing after it is automatically generated). The supported process for
687 //creating a web page involves 3 programs (rather than 1) primarily to circumvent
688 //the involuntary process termination that will occur in some shared environments
689 //if a process consumes too much CPU time.
690 //
691 //The 3 programs in the 3-program suite are:
692 //
693 // filenames_canonize.php (this program):
694 // Converts all names of files in a directory to lower-case, and makes
695 // substitutions for any unusual characters.
696 //
697 // thumbnails_make.php:
698 // Creates thumbnails from recognized image types. The thumbnails are
699 // named relative to the original image file with the suffix "_small".
700 // Only 20 files are converted on each invocation of the program, to
701 // avoid the involuntary process termination that typically occurs in
702 // a shared hosting environment when a process uses too much CPU time.
703 // The program should be run repeatedly until it indicates that it has
704 // no more thumbnails to create.
705 //
706 // If any full-sized photos are modified, any corresponding thumbnails
707 // should be deleted and thumbnails_make.php and indexfile_make.php
708 // should be run again.
709 //
710 // indexfile_make.php
711 // Scans a directory and makes an index file ("index2.php") displaying
712 // all the thumbnail images, each of which link to the corresponding
713 // full-sized image. The index file is tailored to Dave Ashley's
714 // needs, but the created file can be edited and most of the content
715 // pasted into an HTML file. To avoid the accidental loss of
716 // information, any existing "index2.php" file is renamed out of the
717 // way.
718 //
719 //This script is designed to be run manually (rather than automatically invoked
720 //as a result of a web page request). It was written in PHP for convenience
721 //simply because DreamHost (the web hosting company Dave Ashley uses) has as part
722 //of its hosting environment PHP with the ImageMagick library compiled in.
723 //
724 //Usually, this script is invoked using "php <path>/filenames_canonize.php", but
725 //the method of invocation may vary based on computing platform details.

740 // GNU GENERAL PUBLIC LICENSE
741 // Version 3, 29 June 2007
742 //
743 // Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
744 // Everyone is permitted to copy and distribute verbatim copies
745 // of this license document, but changing it is not allowed.
746 //
747 // Preamble
748 //
749 // The GNU General Public License is a free, copyleft license for
750 // software and other kinds of works.
751 //
752 // The licenses for most software and other practical works are designed
753 // to take away your freedom to share and change the works. By contrast,
754 // the GNU General Public License is intended to guarantee your freedom to
755 // share and change all versions of a program--to make sure it remains free
756 // software for all its users. We, the Free Software Foundation, use the
757 // GNU General Public License for most of our software; it applies also to
758 // any other work released this way by its authors. You can apply it to
759 // your programs, too.
760 //
761 // When we speak of free software, we are referring to freedom, not
762 // price. Our General Public Licenses are designed to make sure that you
763 // have the freedom to distribute copies of free software (and charge for
764 // them if you wish), that you receive source code or can get it if you
765 // want it, that you can change the software or use pieces of it in new
766 // free programs, and that you know you can do these things.
767 //
768 // To protect your rights, we need to prevent others from denying you
769 // these rights or asking you to surrender the rights. Therefore, you have
770 // certain responsibilities if you distribute copies of the software, or if
771 // you modify it: responsibilities to respect the freedom of others.
772 //
773 // For example, if you distribute copies of such a program, whether
774 // gratis or for a fee, you must pass on to the recipients the same
775 // freedoms that you received. You must make sure that they, too, receive
776 // or can get the source code. And you must show them these terms so they
777 // know their rights.
778 //
779 // Developers that use the GNU GPL protect your rights with two steps:
780 // (1) assert copyright on the software, and (2) offer you this License
781 // giving you legal permission to copy, distribute and/or modify it.
782 //
783 // For the developers' and authors' protection, the GPL clearly explains
784 // that there is no warranty for this free software. For both users' and
785 // authors' sake, the GPL requires that modified versions be marked as
786 // changed, so that their problems will not be attributed erroneously to
787 // authors of previous versions.
788 //
789 // Some devices are designed to deny users access to install or run
790 // modified versions of the software inside them, although the manufacturer
791 // can do so. This is fundamentally incompatible with the aim of
792 // protecting users' freedom to change the software. The systematic
793 // pattern of such abuse occurs in the area of products for individuals to
794 // use, which is precisely where it is most unacceptable. Therefore, we
795 // have designed this version of the GPL to prohibit the practice for those
796 // products. If such problems arise substantially in other domains, we
797 // stand ready to extend this provision to those domains in future versions
798 // of the GPL, as needed to protect the freedom of users.
799 //
800 // Finally, every program is threatened constantly by software patents.
801 // States should not allow patents to restrict development and use of
802 // software on general-purpose computers, but in those that do, we wish to
803 // avoid the special danger that patents applied to a free program could
804 // make it effectively proprietary. To prevent this, the GPL assures that
805 // patents cannot be used to render the program non-free.
806 //
807 // The precise terms and conditions for copying, distribution and
808 // modification follow.
809 //
810 // TERMS AND CONDITIONS
811 //
812 // 0. Definitions.
813 //
814 // "This License" refers to version 3 of the GNU General Public License.
815 //
816 // "Copyright" also means copyright-like laws that apply to other kinds of
817 // works, such as semiconductor masks.
818 //
819 // "The Program" refers to any copyrightable work licensed under this
820 // License. Each licensee is addressed as "you". "Licensees" and
821 // "recipients" may be individuals or organizations.
822 //
823 // To "modify" a work means to copy from or adapt all or part of the work
824 // in a fashion requiring copyright permission, other than the making of an
825 // exact copy. The resulting work is called a "modified version" of the
826 // earlier work or a work "based on" the earlier work.
827 //
828 // A "covered work" means either the unmodified Program or a work based
829 // on the Program.
830 //
831 // To "propagate" a work means to do anything with it that, without
832 // permission, would make you directly or secondarily liable for
833 // infringement under applicable copyright law, except executing it on a
834 // computer or modifying a private copy. Propagation includes copying,
835 // distribution (with or without modification), making available to the
836 // public, and in some countries other activities as well.
837 //
838 // To "convey" a work means any kind of propagation that enables other
839 // parties to make or receive copies. Mere interaction with a user through
840 // a computer network, with no transfer of a copy, is not conveying.
841 //
842 // An interactive user interface displays "Appropriate Legal Notices"
843 // to the extent that it includes a convenient and prominently visible
844 // feature that (1) displays an appropriate copyright notice, and (2)
845 // tells the user that there is no warranty for the work (except to the
846 // extent that warranties are provided), that licensees may convey the
847 // work under this License, and how to view a copy of this License. If
848 // the interface presents a list of user commands or options, such as a
849 // menu, a prominent item in the list meets this criterion.
850 //
851 // 1. Source Code.
852 //
853 // The "source code" for a work means the preferred form of the work
854 // for making modifications to it. "Object code" means any non-source
855 // form of a work.
856 //
857 // A "Standard Interface" means an interface that either is an official
858 // standard defined by a recognized standards body, or, in the case of
859 // interfaces specified for a particular programming language, one that
860 // is widely used among developers working in that language.
861 //
862 // The "System Libraries" of an executable work include anything, other
863 // than the work as a whole, that (a) is included in the normal form of
864 // packaging a Major Component, but which is not part of that Major
865 // Component, and (b) serves only to enable use of the work with that
866 // Major Component, or to implement a Standard Interface for which an
867 // implementation is available to the public in source code form. A
868 // "Major Component", in this context, means a major essential component
869 // (kernel, window system, and so on) of the specific operating system
870 // (if any) on which the executable work runs, or a compiler used to
871 // produce the work, or an object code interpreter used to run it.
872 //
873 // The "Corresponding Source" for a work in object code form means all
874 // the source code needed to generate, install, and (for an executable
875 // work) run the object code and to modify the work, including scripts to
876 // control those activities. However, it does not include the work's
877 // System Libraries, or general-purpose tools or generally available free
878 // programs which are used unmodified in performing those activities but
879 // which are not part of the work. For example, Corresponding Source
880 // includes interface definition files associated with source files for
881 // the work, and the source code for shared libraries and dynamically
882 // linked subprograms that the work is specifically designed to require,
883 // such as by intimate data communication or control flow between those
884 // subprograms and other parts of the work.
885 //
886 // The Corresponding Source need not include anything that users
887 // can regenerate automatically from other parts of the Corresponding
888 // Source.
889 //
890 // The Corresponding Source for a work in source code form is that
891 // same work.
892 //
893 // 2. Basic Permissions.
894 //
895 // All rights granted under this License are granted for the term of
896 // copyright on the Program, and are irrevocable provided the stated
897 // conditions are met. This License explicitly affirms your unlimited
898 // permission to run the unmodified Program. The output from running a
899 // covered work is covered by this License only if the output, given its
900 // content, constitutes a covered work. This License acknowledges your
901 // rights of fair use or other equivalent, as provided by copyright law.
902 //
903 // You may make, run and propagate covered works that you do not
904 // convey, without conditions so long as your license otherwise remains
905 // in force. You may convey covered works to others for the sole purpose
906 // of having them make modifications exclusively for you, or provide you
907 // with facilities for running those works, provided that you comply with
908 // the terms of this License in conveying all material for which you do
909 // not control copyright. Those thus making or running the covered works
910 // for you must do so exclusively on your behalf, under your direction
911 // and control, on terms that prohibit them from making any copies of
912 // your copyrighted material outside their relationship with you.
913 //
914 // Conveying under any other circumstances is permitted solely under
915 // the conditions stated below. Sublicensing is not allowed; section 10
916 // makes it unnecessary.
917 //
918 // 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
919 //
920 // No covered work shall be deemed part of an effective technological
921 // measure under any applicable law fulfilling obligations under article
922 // 11 of the WIPO copyright treaty adopted on 20 December 1996, or
923 // similar laws prohibiting or restricting circumvention of such
924 // measures.
925 //
926 // When you convey a covered work, you waive any legal power to forbid
927 // circumvention of technological measures to the extent such circumvention
928 // is effected by exercising rights under this License with respect to
929 // the covered work, and you disclaim any intention to limit operation or
930 // modification of the work as a means of enforcing, against the work's
931 // users, your or third parties' legal rights to forbid circumvention of
932 // technological measures.
933 //
934 // 4. Conveying Verbatim Copies.
935 //
936 // You may convey verbatim copies of the Program's source code as you
937 // receive it, in any medium, provided that you conspicuously and
938 // appropriately publish on each copy an appropriate copyright notice;
939 // keep intact all notices stating that this License and any
940 // non-permissive terms added in accord with section 7 apply to the code;
941 // keep intact all notices of the absence of any warranty; and give all
942 // recipients a copy of this License along with the Program.
943 //
944 // You may charge any price or no price for each copy that you convey,
945 // and you may offer support or warranty protection for a fee.
946 //
947 // 5. Conveying Modified Source Versions.
948 //
949 // You may convey a work based on the Program, or the modifications to
950 // produce it from the Program, in the form of source code under the
951 // terms of section 4, provided that you also meet all of these conditions:
952 //
953 // a) The work must carry prominent notices stating that you modified
954 // it, and giving a relevant date.
955 //
956 // b) The work must carry prominent notices stating that it is
957 // released under this License and any conditions added under section
958 // 7. This requirement modifies the requirement in section 4 to
959 // "keep intact all notices".
960 //
961 // c) You must license the entire work, as a whole, under this
962 // License to anyone who comes into possession of a copy. This
963 // License will therefore apply, along with any applicable section 7
964 // additional terms, to the whole of the work, and all its parts,
965 // regardless of how they are packaged. This License gives no
966 // permission to license the work in any other way, but it does not
967 // invalidate such permission if you have separately received it.
968 //
969 // d) If the work has interactive user interfaces, each must display
970 // Appropriate Legal Notices; however, if the Program has interactive
971 // interfaces that do not display Appropriate Legal Notices, your
972 // work need not make them do so.
973 //
974 // A compilation of a covered work with other separate and independent
975 // works, which are not by their nature extensions of the covered work,
976 // and which are not combined with it such as to form a larger program,
977 // in or on a volume of a storage or distribution medium, is called an
978 // "aggregate" if the compilation and its resulting copyright are not
979 // used to limit the access or legal rights of the compilation's users
980 // beyond what the individual works permit. Inclusion of a covered work
981 // in an aggregate does not cause this License to apply to the other
982 // parts of the aggregate.
983 //
984 // 6. Conveying Non-Source Forms.
985 //
986 // You may convey a covered work in object code form under the terms
987 // of sections 4 and 5, provided that you also convey the
988 // machine-readable Corresponding Source under the terms of this License,
989 // in one of these ways:
990 //
991 // a) Convey the object code in, or embodied in, a physical product
992 // (including a physical distribution medium), accompanied by the
993 // Corresponding Source fixed on a durable physical medium
994 // customarily used for software interchange.
995 //
996 // b) Convey the object code in, or embodied in, a physical product
997 // (including a physical distribution medium), accompanied by a
998 // written offer, valid for at least three years and valid for as
999 // long as you offer spare parts or customer support for that product
1000 // model, to give anyone who possesses the object code either (1) a
1001 // copy of the Corresponding Source for all the software in the
1002 // product that is covered by this License, on a durable physical
1003 // medium customarily used for software interchange, for a price no
1004 // more than your reasonable cost of physically performing this
1005 // conveying of source, or (2) access to copy the
1006 // Corresponding Source from a network server at no charge.
1007 //
1008 // c) Convey individual copies of the object code with a copy of the
1009 // written offer to provide the Corresponding Source. This
1010 // alternative is allowed only occasionally and noncommercially, and
1011 // only if you received the object code with such an offer, in accord
1012 // with subsection 6b.
1013 //
1014 // d) Convey the object code by offering access from a designated
1015 // place (gratis or for a charge), and offer equivalent access to the
1016 // Corresponding Source in the same way through the same place at no
1017 // further charge. You need not require recipients to copy the
1018 // Corresponding Source along with the object code. If the place to
1019 // copy the object code is a network server, the Corresponding Source
1020 // may be on a different server (operated by you or a third party)
1021 // that supports equivalent copying facilities, provided you maintain
1022 // clear directions next to the object code saying where to find the
1023 // Corresponding Source. Regardless of what server hosts the
1024 // Corresponding Source, you remain obligated to ensure that it is
1025 // available for as long as needed to satisfy these requirements.
1026 //
1027 // e) Convey the object code using peer-to-peer transmission, provided
1028 // you inform other peers where the object code and Corresponding
1029 // Source of the work are being offered to the general public at no
1030 // charge under subsection 6d.
1031 //
1032 // A separable portion of the object code, whose source code is excluded
1033 // from the Corresponding Source as a System Library, need not be
1034 // included in conveying the object code work.
1035 //
1036 // A "User Product" is either (1) a "consumer product", which means any
1037 // tangible personal property which is normally used for personal, family,
1038 // or household purposes, or (2) anything designed or sold for incorporation
1039 // into a dwelling. In determining whether a product is a consumer product,
1040 // doubtful cases shall be resolved in favor of coverage. For a particular
1041 // product received by a particular user, "normally used" refers to a
1042 // typical or common use of that class of product, regardless of the status
1043 // of the particular user or of the way in which the particular user
1044 // actually uses, or expects or is expected to use, the product. A product
1045 // is a consumer product regardless of whether the product has substantial
1046 // commercial, industrial or non-consumer uses, unless such uses represent
1047 // the only significant mode of use of the product.
1048 //
1049 // "Installation Information" for a User Product means any methods,
1050 // procedures, authorization keys, or other information required to install
1051 // and execute modified versions of a covered work in that User Product from
1052 // a modified version of its Corresponding Source. The information must
1053 // suffice to ensure that the continued functioning of the modified object
1054 // code is in no case prevented or interfered with solely because
1055 // modification has been made.
1056 //
1057 // If you convey an object code work under this section in, or with, or
1058 // specifically for use in, a User Product, and the conveying occurs as
1059 // part of a transaction in which the right of possession and use of the
1060 // User Product is transferred to the recipient in perpetuity or for a
1061 // fixed term (regardless of how the transaction is characterized), the
1062 // Corresponding Source conveyed under this section must be accompanied
1063 // by the Installation Information. But this requirement does not apply
1064 // if neither you nor any third party retains the ability to install
1065 // modified object code on the User Product (for example, the work has
1066 // been installed in ROM).
1067 //
1068 // The requirement to provide Installation Information does not include a
1069 // requirement to continue to provide support service, warranty, or updates
1070 // for a work that has been modified or installed by the recipient, or for
1071 // the User Product in which it has been modified or installed. Access to a
1072 // network may be denied when the modification itself materially and
1073 // adversely affects the operation of the network or violates the rules and
1074 // protocols for communication across the network.
1075 //
1076 // Corresponding Source conveyed, and Installation Information provided,
1077 // in accord with this section must be in a format that is publicly
1078 // documented (and with an implementation available to the public in
1079 // source code form), and must require no special password or key for
1080 // unpacking, reading or copying.
1081 //
1082 // 7. Additional Terms.
1083 //
1084 // "Additional permissions" are terms that supplement the terms of this
1085 // License by making exceptions from one or more of its conditions.
1086 // Additional permissions that are applicable to the entire Program shall
1087 // be treated as though they were included in this License, to the extent
1088 // that they are valid under applicable law. If additional permissions
1089 // apply only to part of the Program, that part may be used separately
1090 // under those permissions, but the entire Program remains governed by
1091 // this License without regard to the additional permissions.
1092 //
1093 // When you convey a copy of a covered work, you may at your option
1094 // remove any additional permissions from that copy, or from any part of
1095 // it. (Additional permissions may be written to require their own
1096 // removal in certain cases when you modify the work.) You may place
1097 // additional permissions on material, added by you to a covered work,
1098 // for which you have or can give appropriate copyright permission.
1099 //
1100 // Notwithstanding any other provision of this License, for material you
1101 // add to a covered work, you may (if authorized by the copyright holders of
1102 // that material) supplement the terms of this License with terms:
1103 //
1104 // a) Disclaiming warranty or limiting liability differently from the
1105 // terms of sections 15 and 16 of this License; or
1106 //
1107 // b) Requiring preservation of specified reasonable legal notices or
1108 // author attributions in that material or in the Appropriate Legal
1109 // Notices displayed by works containing it; or
1110 //
1111 // c) Prohibiting misrepresentation of the origin of that material, or
1112 // requiring that modified versions of such material be marked in
1113 // reasonable ways as different from the original version; or
1114 //
1115 // d) Limiting the use for publicity purposes of names of licensors or
1116 // authors of the material; or
1117 //
1118 // e) Declining to grant rights under trademark law for use of some
1119 // trade names, trademarks, or service marks; or
1120 //
1121 // f) Requiring indemnification of licensors and authors of that
1122 // material by anyone who conveys the material (or modified versions of
1123 // it) with contractual assumptions of liability to the recipient, for
1124 // any liability that these contractual assumptions directly impose on
1125 // those licensors and authors.
1126 //
1127 // All other non-permissive additional terms are considered "further
1128 // restrictions" within the meaning of section 10. If the Program as you
1129 // received it, or any part of it, contains a notice stating that it is
1130 // governed by this License along with a term that is a further
1131 // restriction, you may remove that term. If a license document contains
1132 // a further restriction but permits relicensing or conveying under this
1133 // License, you may add to a covered work material governed by the terms
1134 // of that license document, provided that the further restriction does
1135 // not survive such relicensing or conveying.
1136 //
1137 // If you add terms to a covered work in accord with this section, you
1138 // must place, in the relevant source files, a statement of the
1139 // additional terms that apply to those files, or a notice indicating
1140 // where to find the applicable terms.
1141 //
1142 // Additional terms, permissive or non-permissive, may be stated in the
1143 // form of a separately written license, or stated as exceptions;
1144 // the above requirements apply either way.
1145 //
1146 // 8. Termination.
1147 //
1148 // You may not propagate or modify a covered work except as expressly
1149 // provided under this License. Any attempt otherwise to propagate or
1150 // modify it is void, and will automatically terminate your rights under
1151 // this License (including any patent licenses granted under the third
1152 // paragraph of section 11).
1153 //
1154 // However, if you cease all violation of this License, then your
1155 // license from a particular copyright holder is reinstated (a)
1156 // provisionally, unless and until the copyright holder explicitly and
1157 // finally terminates your license, and (b) permanently, if the copyright
1158 // holder fails to notify you of the violation by some reasonable means
1159 // prior to 60 days after the cessation.
1160 //
1161 // Moreover, your license from a particular copyright holder is
1162 // reinstated permanently if the copyright holder notifies you of the
1163 // violation by some reasonable means, this is the first time you have
1164 // received notice of violation of this License (for any work) from that
1165 // copyright holder, and you cure the violation prior to 30 days after
1166 // your receipt of the notice.
1167 //
1168 // Termination of your rights under this section does not terminate the
1169 // licenses of parties who have received copies or rights from you under
1170 // this License. If your rights have been terminated and not permanently
1171 // reinstated, you do not qualify to receive new licenses for the same
1172 // material under section 10.
1173 //
1174 // 9. Acceptance Not Required for Having Copies.
1175 //
1176 // You are not required to accept this License in order to receive or
1177 // run a copy of the Program. Ancillary propagation of a covered work
1178 // occurring solely as a consequence of using peer-to-peer transmission
1179 // to receive a copy likewise does not require acceptance. However,
1180 // nothing other than this License grants you permission to propagate or
1181 // modify any covered work. These actions infringe copyright if you do
1182 // not accept this License. Therefore, by modifying or propagating a
1183 // covered work, you indicate your acceptance of this License to do so.
1184 //
1185 // 10. Automatic Licensing of Downstream Recipients.
1186 //
1187 // Each time you convey a covered work, the recipient automatically
1188 // receives a license from the original licensors, to run, modify and
1189 // propagate that work, subject to this License. You are not responsible
1190 // for enforcing compliance by third parties with this License.
1191 //
1192 // An "entity transaction" is a transaction transferring control of an
1193 // organization, or substantially all assets of one, or subdividing an
1194 // organization, or merging organizations. If propagation of a covered
1195 // work results from an entity transaction, each party to that
1196 // transaction who receives a copy of the work also receives whatever
1197 // licenses to the work the party's predecessor in interest had or could
1198 // give under the previous paragraph, plus a right to possession of the
1199 // Corresponding Source of the work from the predecessor in interest, if
1200 // the predecessor has it or can get it with reasonable efforts.
1201 //
1202 // You may not impose any further restrictions on the exercise of the
1203 // rights granted or affirmed under this License. For example, you may
1204 // not impose a license fee, royalty, or other charge for exercise of
1205 // rights granted under this License, and you may not initiate litigation
1206 // (including a cross-claim or counterclaim in a lawsuit) alleging that
1207 // any patent claim is infringed by making, using, selling, offering for
1208 // sale, or importing the Program or any portion of it.
1209 //
1210 // 11. Patents.
1211 //
1212 // A "contributor" is a copyright holder who authorizes use under this
1213 // License of the Program or a work on which the Program is based. The
1214 // work thus licensed is called the contributor's "contributor version".
1215 //
1216 // A contributor's "essential patent claims" are all patent claims
1217 // owned or controlled by the contributor, whether already acquired or
1218 // hereafter acquired, that would be infringed by some manner, permitted
1219 // by this License, of making, using, or selling its contributor version,
1220 // but do not include claims that would be infringed only as a
1221 // consequence of further modification of the contributor version. For
1222 // purposes of this definition, "control" includes the right to grant
1223 // patent sublicenses in a manner consistent with the requirements of
1224 // this License.
1225 //
1226 // Each contributor grants you a non-exclusive, worldwide, royalty-free
1227 // patent license under the contributor's essential patent claims, to
1228 // make, use, sell, offer for sale, import and otherwise run, modify and
1229 // propagate the contents of its contributor version.
1230 //
1231 // In the following three paragraphs, a "patent license" is any express
1232 // agreement or commitment, however denominated, not to enforce a patent
1233 // (such as an express permission to practice a patent or covenant not to
1234 // sue for patent infringement). To "grant" such a patent license to a
1235 // party means to make such an agreement or commitment not to enforce a
1236 // patent against the party.
1237 //
1238 // If you convey a covered work, knowingly relying on a patent license,
1239 // and the Corresponding Source of the work is not available for anyone
1240 // to copy, free of charge and under the terms of this License, through a
1241 // publicly available network server or other readily accessible means,
1242 // then you must either (1) cause the Corresponding Source to be so
1243 // available, or (2) arrange to deprive yourself of the benefit of the
1244 // patent license for this particular work, or (3) arrange, in a manner
1245 // consistent with the requirements of this License, to extend the patent
1246 // license to downstream recipients. "Knowingly relying" means you have
1247 // actual knowledge that, but for the patent license, your conveying the
1248 // covered work in a country, or your recipient's use of the covered work
1249 // in a country, would infringe one or more identifiable patents in that
1250 // country that you have reason to believe are valid.
1251 //
1252 // If, pursuant to or in connection with a single transaction or
1253 // arrangement, you convey, or propagate by procuring conveyance of, a
1254 // covered work, and grant a patent license to some of the parties
1255 // receiving the covered work authorizing them to use, propagate, modify
1256 // or convey a specific copy of the covered work, then the patent license
1257 // you grant is automatically extended to all recipients of the covered
1258 // work and works based on it.
1259 //
1260 // A patent license is "discriminatory" if it does not include within
1261 // the scope of its coverage, prohibits the exercise of, or is
1262 // conditioned on the non-exercise of one or more of the rights that are
1263 // specifically granted under this License. You may not convey a covered
1264 // work if you are a party to an arrangement with a third party that is
1265 // in the business of distributing software, under which you make payment
1266 // to the third party based on the extent of your activity of conveying
1267 // the work, and under which the third party grants, to any of the
1268 // parties who would receive the covered work from you, a discriminatory
1269 // patent license (a) in connection with copies of the covered work
1270 // conveyed by you (or copies made from those copies), or (b) primarily
1271 // for and in connection with specific products or compilations that
1272 // contain the covered work, unless you entered into that arrangement,
1273 // or that patent license was granted, prior to 28 March 2007.
1274 //
1275 // Nothing in this License shall be construed as excluding or limiting
1276 // any implied license or other defenses to infringement that may
1277 // otherwise be available to you under applicable patent law.
1278 //
1279 // 12. No Surrender of Others' Freedom.
1280 //
1281 // If conditions are imposed on you (whether by court order, agreement or
1282 // otherwise) that contradict the conditions of this License, they do not
1283 // excuse you from the conditions of this License. If you cannot convey a
1284 // covered work so as to satisfy simultaneously your obligations under this
1285 // License and any other pertinent obligations, then as a consequence you may
1286 // not convey it at all. For example, if you agree to terms that obligate you
1287 // to collect a royalty for further conveying from those to whom you convey
1288 // the Program, the only way you could satisfy both those terms and this
1289 // License would be to refrain entirely from conveying the Program.
1290 //
1291 // 13. Use with the GNU Affero General Public License.
1292 //
1293 // Notwithstanding any other provision of this License, you have
1294 // permission to link or combine any covered work with a work licensed
1295 // under version 3 of the GNU Affero General Public License into a single
1296 // combined work, and to convey the resulting work. The terms of this
1297 // License will continue to apply to the part which is the covered work,
1298 // but the special requirements of the GNU Affero General Public License,
1299 // section 13, concerning interaction through a network will apply to the
1300 // combination as such.
1301 //
1302 // 14. Revised Versions of this License.
1303 //
1304 // The Free Software Foundation may publish revised and/or new versions of
1305 // the GNU General Public License from time to time. Such new versions will
1306 // be similar in spirit to the present version, but may differ in detail to
1307 // address new problems or concerns.
1308 //
1309 // Each version is given a distinguishing version number. If the
1310 // Program specifies that a certain numbered version of the GNU General
1311 // Public License "or any later version" applies to it, you have the
1312 // option of following the terms and conditions either of that numbered
1313 // version or of any later version published by the Free Software
1314 // Foundation. If the Program does not specify a version number of the
1315 // GNU General Public License, you may choose any version ever published
1316 // by the Free Software Foundation.
1317 //
1318 // If the Program specifies that a proxy can decide which future
1319 // versions of the GNU General Public License can be used, that proxy's
1320 // public statement of acceptance of a version permanently authorizes you
1321 // to choose that version for the Program.
1322 //
1323 // Later license versions may give you additional or different
1324 // permissions. However, no additional obligations are imposed on any
1325 // author or copyright holder as a result of your choosing to follow a
1326 // later version.
1327 //
1328 // 15. Disclaimer of Warranty.
1329 //
1330 // THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
1331 // APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
1332 // HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
1333 // OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
1334 // THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
1335 // PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
1336 // IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
1337 // ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
1338 //
1339 // 16. Limitation of Liability.
1340 //
1341 // IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
1342 // WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
1343 // THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
1344 // GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
1345 // USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
1346 // DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
1347 // PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
1348 // EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
1349 // SUCH DAMAGES.
1350 //
1351 // 17. Interpretation of Sections 15 and 16.
1352 //
1353 // If the disclaimer of warranty and limitation of liability provided
1354 // above cannot be given local legal effect according to their terms,
1355 // reviewing courts shall apply local law that most closely approximates
1356 // an absolute waiver of all civil liability in connection with the
1357 // Program, unless a warranty or assumption of liability accompanies a
1358 // copy of the Program in return for a fee.
