8 //This source code and any program in which it is compiled/used is provided under the GNU GENERAL
9 //PUBLIC LICENSE, Version 3, full license text below.
10 //-------------------------------------------------------------------------------------------------
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.>
645 // Copyright (C) <year> <name of author>

651 //
652 // This program is distributed in the hope that it will be useful,

657 // You should have received a copy of the GNU General Public License
658 // along with this program. If not, see <http://www.gnu.org/licenses/>.
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>
666 // This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
667 // This is free software, and you are welcome to redistribute it
668 // under certain conditions; type `show c' for details.
669 //
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.

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
1272 // parties who would receive the covered work from you, a discriminatory
1273 // patent license (a) in connection with copies of the covered work
1274 // conveyed by you (or copies made from those copies), or (b) primarily
1275 // for and in connection with specific products or compilations that
1276 // contain the covered work, unless you entered into that arrangement,
1277 // or that patent license was granted, prior to 28 March 2007.
1278 //
1279 // Nothing in this License shall be construed as excluding or limiting
1280 // any implied license or other defenses to infringement that may
1281 // otherwise be available to you under applicable patent law.
1282 //
1283 // 12. No Surrender of Others' Freedom.
1284 //
1285 // If conditions are imposed on you (whether by court order, agreement or
1286 // otherwise) that contradict the conditions of this License, they do not
1287 // excuse you from the conditions of this License. If you cannot convey a
1288 // covered work so as to satisfy simultaneously your obligations under this
1289 // License and any other pertinent obligations, then as a consequence you may
1290 // not convey it at all. For example, if you agree to terms that obligate you
1291 // to collect a royalty for further conveying from those to whom you convey
1292 // the Program, the only way you could satisfy both those terms and this
1293 // License would be to refrain entirely from conveying the Program.
1294 //
1295 // 13. Use with the GNU Affero General Public License.
1296 //
1297 // Notwithstanding any other provision of this License, you have
1298 // permission to link or combine any covered work with a work licensed
1299 // under version 3 of the GNU Affero General Public License into a single
1300 // combined work, and to convey the resulting work. The terms of this
1301 // License will continue to apply to the part which is the covered work,
1302 // but the special requirements of the GNU Affero General Public License,
1303 // section 13, concerning interaction through a network will apply to the
1304 // combination as such.
1305 //
1306 // 14. Revised Versions of this License.
1307 //
1308 // The Free Software Foundation may publish revised and/or new versions of
1309 // the GNU General Public License from time to time. Such new versions will
1310 // be similar in spirit to the present version, but may differ in detail to
1311 // address new problems or concerns.
1312 //
1313 // Each version is given a distinguishing version number. If the
1314 // Program specifies that a certain numbered version of the GNU General
1315 // Public License "or any later version" applies to it, you have the
1316 // option of following the terms and conditions either of that numbered
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
1319 // GNU General Public License, you may choose any version ever published
1320 // by the Free Software Foundation.
1321 //
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.
1326 //
1327 // Later license versions may give you additional or different
1328 // permissions. However, no additional obligations are imposed on any
1329 // author or copyright holder as a result of your choosing to follow a
1330 // later version.
1331 //
1332 // 15. Disclaimer of Warranty.
1333 //
1334 // THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
1335 // APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
1336 // HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
1337 // OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
1338 // THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
1339 // PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
1340 // IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
1341 // ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
1342 //
1343 // 16. Limitation of Liability.
1344 //
1345 // IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
1346 // WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
1347 // THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
1348 // GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
1349 // USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
1350 // DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
1351 // PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
1352 // EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
1353 // SUCH DAMAGES.
1354 //
1355 // 17. Interpretation of Sections 15 and 16.
1356 //
1357 // If the disclaimer of warranty and limitation of liability provided
1358 // above cannot be given local legal effect according to their terms,
1359 // reviewing courts shall apply local law that most closely approximates
1360 // an absolute waiver of all civil liability in connection with the
1361 // Program, unless a warranty or assumption of liability accompanies a
1362 // copy of the Program in return for a fee.
