5 //Copyright 2006 David T. Ashley
6 //-------------------------------------------------------------------------------------------------
7 //This source code and any program in which it is compiled/used is provided under the GNU GENERAL
8 //PUBLIC LICENSE, Version 3, full license text below.
9 //-------------------------------------------------------------------------------------------------
10 // GNU GENERAL PUBLIC LICENSE
11 // Version 3, 29 June 2007
12 //
13 // Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
14 // Everyone is permitted to copy and distribute verbatim copies
15 // of this license document, but changing it is not allowed.
16 //
17 // Preamble
18 //
19 // The GNU General Public License is a free, copyleft license for
20 //software and other kinds of works.
21 //
22 // The licenses for most software and other practical works are designed
23 //to take away your freedom to share and change the works. By contrast,
24 //the GNU General Public License is intended to guarantee your freedom to
25 //share and change all versions of a program--to make sure it remains free
26 //software for all its users. We, the Free Software Foundation, use the
27 //GNU General Public License for most of our software; it applies also to
28 //any other work released this way by its authors. You can apply it to
29 //your programs, too.
30 //
31 // When we speak of free software, we are referring to freedom, not
32 //price. Our General Public Licenses are designed to make sure that you
33 //have the freedom to distribute copies of free software (and charge for
34 //them if you wish), that you receive source code or can get it if you
35 //want it, that you can change the software or use pieces of it in new
36 //free programs, and that you know you can do these things.
37 //
38 // To protect your rights, we need to prevent others from denying you
39 //these rights or asking you to surrender the rights. Therefore, you have
40 //certain responsibilities if you distribute copies of the software, or if
41 //you modify it: responsibilities to respect the freedom of others.
42 //
43 // For example, if you distribute copies of such a program, whether
44 //gratis or for a fee, you must pass on to the recipients the same
45 //freedoms that you received. You must make sure that they, too, receive
46 //or can get the source code. And you must show them these terms so they
47 //know their rights.
48 //
49 // Developers that use the GNU GPL protect your rights with two steps:
50 //(1) assert copyright on the software, and (2) offer you this License
51 //giving you legal permission to copy, distribute and/or modify it.
52 //
53 // For the developers' and authors' protection, the GPL clearly explains
54 //that there is no warranty for this free software. For both users' and
55 //authors' sake, the GPL requires that modified versions be marked as
56 //changed, so that their problems will not be attributed erroneously to
57 //authors of previous versions.
58 //
59 // Some devices are designed to deny users access to install or run
60 //modified versions of the software inside them, although the manufacturer
61 //can do so. This is fundamentally incompatible with the aim of
62 //protecting users' freedom to change the software. The systematic
63 //pattern of such abuse occurs in the area of products for individuals to
64 //use, which is precisely where it is most unacceptable. Therefore, we
65 //have designed this version of the GPL to prohibit the practice for those
66 //products. If such problems arise substantially in other domains, we
67 //stand ready to extend this provision to those domains in future versions
68 //of the GPL, as needed to protect the freedom of users.
69 //
70 // Finally, every program is threatened constantly by software patents.
71 //States should not allow patents to restrict development and use of
72 //software on general-purpose computers, but in those that do, we wish to
73 //avoid the special danger that patents applied to a free program could
74 //make it effectively proprietary. To prevent this, the GPL assures that
75 //patents cannot be used to render the program non-free.
76 //
77 // The precise terms and conditions for copying, distribution and
78 //modification follow.
79 //
80 // TERMS AND CONDITIONS
81 //
82 // 0. Definitions.
83 //
84 // "This License" refers to version 3 of the GNU General Public License.
85 //
86 // "Copyright" also means copyright-like laws that apply to other kinds of
87 //works, such as semiconductor masks.
88 //
89 // "The Program" refers to any copyrightable work licensed under this
90 //License. Each licensee is addressed as "you". "Licensees" and
91 //"recipients" may be individuals or organizations.
92 //
93 // To "modify" a work means to copy from or adapt all or part of the work
94 //in a fashion requiring copyright permission, other than the making of an
95 //exact copy. The resulting work is called a "modified version" of the
96 //earlier work or a work "based on" the earlier work.
97 //
98 // A "covered work" means either the unmodified Program or a work based
99 //on the Program.
100 //
101 // To "propagate" a work means to do anything with it that, without
102 //permission, would make you directly or secondarily liable for
103 //infringement under applicable copyright law, except executing it on a
104 //computer or modifying a private copy. Propagation includes copying,
105 //distribution (with or without modification), making available to the
106 //public, and in some countries other activities as well.
107 //
108 // To "convey" a work means any kind of propagation that enables other
109 //parties to make or receive copies. Mere interaction with a user through
110 //a computer network, with no transfer of a copy, is not conveying.
111 //
112 // An interactive user interface displays "Appropriate Legal Notices"
113 //to the extent that it includes a convenient and prominently visible
114 //feature that (1) displays an appropriate copyright notice, and (2)
115 //tells the user that there is no warranty for the work (except to the
116 //extent that warranties are provided), that licensees may convey the
117 //work under this License, and how to view a copy of this License. If
118 //the interface presents a list of user commands or options, such as a
119 //menu, a prominent item in the list meets this criterion.
120 //
121 // 1. Source Code.
122 //
123 // The "source code" for a work means the preferred form of the work
124 //for making modifications to it. "Object code" means any non-source
125 //form of a work.
126 //
127 // A "Standard Interface" means an interface that either is an official
128 //standard defined by a recognized standards body, or, in the case of
129 //interfaces specified for a particular programming language, one that
130 //is widely used among developers working in that language.
131 //
132 // The "System Libraries" of an executable work include anything, other
133 //than the work as a whole, that (a) is included in the normal form of
134 //packaging a Major Component, but which is not part of that Major
135 //Component, and (b) serves only to enable use of the work with that
136 //Major Component, or to implement a Standard Interface for which an
137 //implementation is available to the public in source code form. A
138 //"Major Component", in this context, means a major essential component
139 //(kernel, window system, and so on) of the specific operating system
140 //(if any) on which the executable work runs, or a compiler used to
141 //produce the work, or an object code interpreter used to run it.
142 //
143 // The "Corresponding Source" for a work in object code form means all
144 //the source code needed to generate, install, and (for an executable
145 //work) run the object code and to modify the work, including scripts to
146 //control those activities. However, it does not include the work's
147 //System Libraries, or general-purpose tools or generally available free
148 //programs which are used unmodified in performing those activities but
149 //which are not part of the work. For example, Corresponding Source
150 //includes interface definition files associated with source files for
151 //the work, and the source code for shared libraries and dynamically
152 //linked subprograms that the work is specifically designed to require,
153 //such as by intimate data communication or control flow between those
154 //subprograms and other parts of the work.
155 //
156 // The Corresponding Source need not include anything that users
157 //can regenerate automatically from other parts of the Corresponding
158 //Source.
159 //
160 // The Corresponding Source for a work in source code form is that
161 //same work.
162 //
163 // 2. Basic Permissions.
164 //
165 // All rights granted under this License are granted for the term of
166 //copyright on the Program, and are irrevocable provided the stated
167 //conditions are met. This License explicitly affirms your unlimited
168 //permission to run the unmodified Program. The output from running a
169 //covered work is covered by this License only if the output, given its
170 //content, constitutes a covered work. This License acknowledges your
171 //rights of fair use or other equivalent, as provided by copyright law.
172 //
173 // You may make, run and propagate covered works that you do not
174 //convey, without conditions so long as your license otherwise remains
175 //in force. You may convey covered works to others for the sole purpose
176 //of having them make modifications exclusively for you, or provide you
177 //with facilities for running those works, provided that you comply with
178 //the terms of this License in conveying all material for which you do
179 //not control copyright. Those thus making or running the covered works
180 //for you must do so exclusively on your behalf, under your direction
181 //and control, on terms that prohibit them from making any copies of
182 //your copyrighted material outside their relationship with you.
183 //
184 // Conveying under any other circumstances is permitted solely under
185 //the conditions stated below. Sublicensing is not allowed; section 10
186 //makes it unnecessary.
187 //
188 // 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
189 //
190 // No covered work shall be deemed part of an effective technological
191 //measure under any applicable law fulfilling obligations under article
192 //11 of the WIPO copyright treaty adopted on 20 December 1996, or
193 //similar laws prohibiting or restricting circumvention of such
194 //measures.
195 //
196 // When you convey a covered work, you waive any legal power to forbid
197 //circumvention of technological measures to the extent such circumvention
198 //is effected by exercising rights under this License with respect to
199 //the covered work, and you disclaim any intention to limit operation or
200 //modification of the work as a means of enforcing, against the work's
201 //users, your or third parties' legal rights to forbid circumvention of
202 //technological measures.
203 //
204 // 4. Conveying Verbatim Copies.
205 //
206 // You may convey verbatim copies of the Program's source code as you
207 //receive it, in any medium, provided that you conspicuously and
208 //appropriately publish on each copy an appropriate copyright notice;
209 //keep intact all notices stating that this License and any
210 //non-permissive terms added in accord with section 7 apply to the code;
211 //keep intact all notices of the absence of any warranty; and give all
212 //recipients a copy of this License along with the Program.
213 //
214 // You may charge any price or no price for each copy that you convey,
215 //and you may offer support or warranty protection for a fee.
216 //
217 // 5. Conveying Modified Source Versions.
218 //
219 // You may convey a work based on the Program, or the modifications to
220 //produce it from the Program, in the form of source code under the
221 //terms of section 4, provided that you also meet all of these conditions:
222 //
223 // a) The work must carry prominent notices stating that you modified
224 // it, and giving a relevant date.
225 //
226 // b) The work must carry prominent notices stating that it is
227 // released under this License and any conditions added under section
228 // 7. This requirement modifies the requirement in section 4 to
229 // "keep intact all notices".
230 //
231 // c) You must license the entire work, as a whole, under this
232 // License to anyone who comes into possession of a copy. This
233 // License will therefore apply, along with any applicable section 7
234 // additional terms, to the whole of the work, and all its parts,
235 // regardless of how they are packaged. This License gives no
236 // permission to license the work in any other way, but it does not
237 // invalidate such permission if you have separately received it.
238 //
239 // d) If the work has interactive user interfaces, each must display
240 // Appropriate Legal Notices; however, if the Program has interactive
241 // interfaces that do not display Appropriate Legal Notices, your
242 // work need not make them do so.
243 //
244 // A compilation of a covered work with other separate and independent
245 //works, which are not by their nature extensions of the covered work,
246 //and which are not combined with it such as to form a larger program,
247 //in or on a volume of a storage or distribution medium, is called an
248 //"aggregate" if the compilation and its resulting copyright are not
249 //used to limit the access or legal rights of the compilation's users
250 //beyond what the individual works permit. Inclusion of a covered work
251 //in an aggregate does not cause this License to apply to the other
252 //parts of the aggregate.
253 //
254 // 6. Conveying Non-Source Forms.
255 //
256 // You may convey a covered work in object code form under the terms
257 //of sections 4 and 5, provided that you also convey the
258 //machine-readable Corresponding Source under the terms of this License,
259 //in one of these ways:
260 //
261 // a) Convey the object code in, or embodied in, a physical product
262 // (including a physical distribution medium), accompanied by the
263 // Corresponding Source fixed on a durable physical medium
264 // customarily used for software interchange.
265 //
266 // b) Convey the object code in, or embodied in, a physical product
267 // (including a physical distribution medium), accompanied by a
268 // written offer, valid for at least three years and valid for as
269 // long as you offer spare parts or customer support for that product
270 // model, to give anyone who possesses the object code either (1) a
271 // copy of the Corresponding Source for all the software in the
272 // product that is covered by this License, on a durable physical
273 // medium customarily used for software interchange, for a price no
274 // more than your reasonable cost of physically performing this
275 // conveying of source, or (2) access to copy the
276 // Corresponding Source from a network server at no charge.
277 //
278 // c) Convey individual copies of the object code with a copy of the
279 // written offer to provide the Corresponding Source. This
280 // alternative is allowed only occasionally and noncommercially, and
281 // only if you received the object code with such an offer, in accord
282 // with subsection 6b.
283 //
284 // d) Convey the object code by offering access from a designated
285 // place (gratis or for a charge), and offer equivalent access to the
286 // Corresponding Source in the same way through the same place at no
287 // further charge. You need not require recipients to copy the
288 // Corresponding Source along with the object code. If the place to
289 // copy the object code is a network server, the Corresponding Source
290 // may be on a different server (operated by you or a third party)
291 // that supports equivalent copying facilities, provided you maintain
292 // clear directions next to the object code saying where to find the
293 // Corresponding Source. Regardless of what server hosts the
294 // Corresponding Source, you remain obligated to ensure that it is
295 // available for as long as needed to satisfy these requirements.
296 //
297 // e) Convey the object code using peer-to-peer transmission, provided
298 // you inform other peers where the object code and Corresponding
299 // Source of the work are being offered to the general public at no
300 // charge under subsection 6d.
301 //
302 // A separable portion of the object code, whose source code is excluded
303 //from the Corresponding Source as a System Library, need not be
304 //included in conveying the object code work.
305 //
306 // A "User Product" is either (1) a "consumer product", which means any
307 //tangible personal property which is normally used for personal, family,
308 //or household purposes, or (2) anything designed or sold for incorporation
309 //into a dwelling. In determining whether a product is a consumer product,
310 //doubtful cases shall be resolved in favor of coverage. For a particular
311 //product received by a particular user, "normally used" refers to a
312 //typical or common use of that class of product, regardless of the status
313 //of the particular user or of the way in which the particular user
314 //actually uses, or expects or is expected to use, the product. A product
315 //is a consumer product regardless of whether the product has substantial
316 //commercial, industrial or non-consumer uses, unless such uses represent
317 //the only significant mode of use of the product.
318 //
319 // "Installation Information" for a User Product means any methods,
320 //procedures, authorization keys, or other information required to install
321 //and execute modified versions of a covered work in that User Product from
322 //a modified version of its Corresponding Source. The information must
323 //suffice to ensure that the continued functioning of the modified object
324 //code is in no case prevented or interfered with solely because
325 //modification has been made.
326 //
327 // If you convey an object code work under this section in, or with, or
328 //specifically for use in, a User Product, and the conveying occurs as
329 //part of a transaction in which the right of possession and use of the
330 //User Product is transferred to the recipient in perpetuity or for a
331 //fixed term (regardless of how the transaction is characterized), the
332 //Corresponding Source conveyed under this section must be accompanied
333 //by the Installation Information. But this requirement does not apply
334 //if neither you nor any third party retains the ability to install
335 //modified object code on the User Product (for example, the work has
336 //been installed in ROM).
337 //
338 // The requirement to provide Installation Information does not include a
339 //requirement to continue to provide support service, warranty, or updates
340 //for a work that has been modified or installed by the recipient, or for
341 //the User Product in which it has been modified or installed. Access to a
342 //network may be denied when the modification itself materially and
343 //adversely affects the operation of the network or violates the rules and
344 //protocols for communication across the network.
345 //
346 // Corresponding Source conveyed, and Installation Information provided,
347 //in accord with this section must be in a format that is publicly
348 //documented (and with an implementation available to the public in
349 //source code form), and must require no special password or key for
350 //unpacking, reading or copying.
351 //
352 // 7. Additional Terms.
353 //
354 // "Additional permissions" are terms that supplement the terms of this
355 //License by making exceptions from one or more of its conditions.
356 //Additional permissions that are applicable to the entire Program shall
357 //be treated as though they were included in this License, to the extent
358 //that they are valid under applicable law. If additional permissions
359 //apply only to part of the Program, that part may be used separately
360 //under those permissions, but the entire Program remains governed by
361 //this License without regard to the additional permissions.
362 //
363 // When you convey a copy of a covered work, you may at your option
364 //remove any additional permissions from that copy, or from any part of
365 //it. (Additional permissions may be written to require their own
366 //removal in certain cases when you modify the work.) You may place
367 //additional permissions on material, added by you to a covered work,
368 //for which you have or can give appropriate copyright permission.
369 //
370 // Notwithstanding any other provision of this License, for material you
371 //add to a covered work, you may (if authorized by the copyright holders of
372 //that material) supplement the terms of this License with terms:
373 //
374 // a) Disclaiming warranty or limiting liability differently from the
375 // terms of sections 15 and 16 of this License; or
376 //
377 // b) Requiring preservation of specified reasonable legal notices or
378 // author attributions in that material or in the Appropriate Legal
379 // Notices displayed by works containing it; or
380 //
381 // c) Prohibiting misrepresentation of the origin of that material, or
382 // requiring that modified versions of such material be marked in
383 // reasonable ways as different from the original version; or
384 //
385 // d) Limiting the use for publicity purposes of names of licensors or
386 // authors of the material; or
387 //
388 // e) Declining to grant rights under trademark law for use of some
389 // trade names, trademarks, or service marks; or
390 //
391 // f) Requiring indemnification of licensors and authors of that
392 // material by anyone who conveys the material (or modified versions of
393 // it) with contractual assumptions of liability to the recipient, for
394 // any liability that these contractual assumptions directly impose on
395 // those licensors and authors.
396 //
397 // All other non-permissive additional terms are considered "further
398 //restrictions" within the meaning of section 10. If the Program as you
399 //received it, or any part of it, contains a notice stating that it is
400 //governed by this License along with a term that is a further
401 //restriction, you may remove that term. If a license document contains
402 //a further restriction but permits relicensing or conveying under this
403 //License, you may add to a covered work material governed by the terms
404 //of that license document, provided that the further restriction does
405 //not survive such relicensing or conveying.
406 //
407 // If you add terms to a covered work in accord with this section, you
408 //must place, in the relevant source files, a statement of the
409 //additional terms that apply to those files, or a notice indicating
410 //where to find the applicable terms.
411 //
412 // Additional terms, permissive or non-permissive, may be stated in the
413 //form of a separately written license, or stated as exceptions;
414 //the above requirements apply either way.
415 //
416 // 8. Termination.
417 //
418 // You may not propagate or modify a covered work except as expressly
419 //provided under this License. Any attempt otherwise to propagate or
420 //modify it is void, and will automatically terminate your rights under
421 //this License (including any patent licenses granted under the third
422 //paragraph of section 11).
423 //
424 // However, if you cease all violation of this License, then your
425 //license from a particular copyright holder is reinstated (a)
426 //provisionally, unless and until the copyright holder explicitly and
427 //finally terminates your license, and (b) permanently, if the copyright
428 //holder fails to notify you of the violation by some reasonable means
429 //prior to 60 days after the cessation.
430 //
431 // Moreover, your license from a particular copyright holder is
432 //reinstated permanently if the copyright holder notifies you of the
433 //violation by some reasonable means, this is the first time you have
434 //received notice of violation of this License (for any work) from that
435 //copyright holder, and you cure the violation prior to 30 days after
436 //your receipt of the notice.
437 //
438 // Termination of your rights under this section does not terminate the
439 //licenses of parties who have received copies or rights from you under
440 //this License. If your rights have been terminated and not permanently
441 //reinstated, you do not qualify to receive new licenses for the same
442 //material under section 10.
443 //
444 // 9. Acceptance Not Required for Having Copies.
445 //
446 // You are not required to accept this License in order to receive or
447 //run a copy of the Program. Ancillary propagation of a covered work
448 //occurring solely as a consequence of using peer-to-peer transmission
449 //to receive a copy likewise does not require acceptance. However,
450 //nothing other than this License grants you permission to propagate or
451 //modify any covered work. These actions infringe copyright if you do
452 //not accept this License. Therefore, by modifying or propagating a
453 //covered work, you indicate your acceptance of this License to do so.
454 //
455 // 10. Automatic Licensing of Downstream Recipients.
456 //
457 // Each time you convey a covered work, the recipient automatically
458 //receives a license from the original licensors, to run, modify and
459 //propagate that work, subject to this License. You are not responsible
460 //for enforcing compliance by third parties with this License.
461 //
462 // An "entity transaction" is a transaction transferring control of an
463 //organization, or substantially all assets of one, or subdividing an
464 //organization, or merging organizations. If propagation of a covered
465 //work results from an entity transaction, each party to that
466 //transaction who receives a copy of the work also receives whatever
467 //licenses to the work the party's predecessor in interest had or could
468 //give under the previous paragraph, plus a right to possession of the
469 //Corresponding Source of the work from the predecessor in interest, if
470 //the predecessor has it or can get it with reasonable efforts.
471 //
472 // You may not impose any further restrictions on the exercise of the
473 //rights granted or affirmed under this License. For example, you may
474 //not impose a license fee, royalty, or other charge for exercise of
475 //rights granted under this License, and you may not initiate litigation
476 //(including a cross-claim or counterclaim in a lawsuit) alleging that
477 //any patent claim is infringed by making, using, selling, offering for
478 //sale, or importing the Program or any portion of it.
479 //
480 // 11. Patents.
481 //
482 // A "contributor" is a copyright holder who authorizes use under this
483 //License of the Program or a work on which the Program is based. The
484 //work thus licensed is called the contributor's "contributor version".
485 //
486 // A contributor's "essential patent claims" are all patent claims
487 //owned or controlled by the contributor, whether already acquired or
488 //hereafter acquired, that would be infringed by some manner, permitted
489 //by this License, of making, using, or selling its contributor version,
490 //but do not include claims that would be infringed only as a
491 //consequence of further modification of the contributor version. For
492 //purposes of this definition, "control" includes the right to grant
493 //patent sublicenses in a manner consistent with the requirements of
494 //this License.
495 //
496 // Each contributor grants you a non-exclusive, worldwide, royalty-free
497 //patent license under the contributor's essential patent claims, to
498 //make, use, sell, offer for sale, import and otherwise run, modify and
499 //propagate the contents of its contributor version.
500 //
501 // In the following three paragraphs, a "patent license" is any express
502 //agreement or commitment, however denominated, not to enforce a patent
503 //(such as an express permission to practice a patent or covenant not to
504 //sue for patent infringement). To "grant" such a patent license to a
505 //party means to make such an agreement or commitment not to enforce a
506 //patent against the party.
507 //
508 // If you convey a covered work, knowingly relying on a patent license,
509 //and the Corresponding Source of the work is not available for anyone
510 //to copy, free of charge and under the terms of this License, through a
511 //publicly available network server or other readily accessible means,
512 //then you must either (1) cause the Corresponding Source to be so
513 //available, or (2) arrange to deprive yourself of the benefit of the
514 //patent license for this particular work, or (3) arrange, in a manner
515 //consistent with the requirements of this License, to extend the patent
516 //license to downstream recipients. "Knowingly relying" means you have
517 //actual knowledge that, but for the patent license, your conveying the
518 //covered work in a country, or your recipient's use of the covered work
519 //in a country, would infringe one or more identifiable patents in that
520 //country that you have reason to believe are valid.
521 //
522 // If, pursuant to or in connection with a single transaction or
523 //arrangement, you convey, or propagate by procuring conveyance of, a
524 //covered work, and grant a patent license to some of the parties
525 //receiving the covered work authorizing them to use, propagate, modify
526 //or convey a specific copy of the covered work, then the patent license
527 //you grant is automatically extended to all recipients of the covered
528 //work and works based on it.
529 //
530 // A patent license is "discriminatory" if it does not include within
531 //the scope of its coverage, prohibits the exercise of, or is
532 //conditioned on the non-exercise of one or more of the rights that are
533 //specifically granted under this License. You may not convey a covered
534 //work if you are a party to an arrangement with a third party that is
535 //in the business of distributing software, under which you make payment
536 //to the third party based on the extent of your activity of conveying
537 //the work, and under which the third party grants, to any of the
538 //parties who would receive the covered work from you, a discriminatory
539 //patent license (a) in connection with copies of the covered work
540 //conveyed by you (or copies made from those copies), or (b) primarily
541 //for and in connection with specific products or compilations that
542 //contain the covered work, unless you entered into that arrangement,
543 //or that patent license was granted, prior to 28 March 2007.
544 //
545 // Nothing in this License shall be construed as excluding or limiting
546 //any implied license or other defenses to infringement that may
547 //otherwise be available to you under applicable patent law.
548 //
549 // 12. No Surrender of Others' Freedom.
550 //
551 // If conditions are imposed on you (whether by court order, agreement or
552 //otherwise) that contradict the conditions of this License, they do not
553 //excuse you from the conditions of this License. If you cannot convey a
554 //covered work so as to satisfy simultaneously your obligations under this
555 //License and any other pertinent obligations, then as a consequence you may
556 //not convey it at all. For example, if you agree to terms that obligate you
557 //to collect a royalty for further conveying from those to whom you convey
558 //the Program, the only way you could satisfy both those terms and this
559 //License would be to refrain entirely from conveying the Program.
560 //
561 // 13. Use with the GNU Affero General Public License.
562 //
563 // Notwithstanding any other provision of this License, you have
564 //permission to link or combine any covered work with a work licensed
565 //under version 3 of the GNU Affero General Public License into a single
566 //combined work, and to convey the resulting work. The terms of this
567 //License will continue to apply to the part which is the covered work,
568 //but the special requirements of the GNU Affero General Public License,
569 //section 13, concerning interaction through a network will apply to the
570 //combination as such.
571 //
572 // 14. Revised Versions of this License.
573 //
574 // The Free Software Foundation may publish revised and/or new versions of
575 //the GNU General Public License from time to time. Such new versions will
576 //be similar in spirit to the present version, but may differ in detail to
577 //address new problems or concerns.
578 //
579 // Each version is given a distinguishing version number. If the
580 //Program specifies that a certain numbered version of the GNU General
581 //Public License "or any later version" applies to it, you have the
582 //option of following the terms and conditions either of that numbered
583 //version or of any later version published by the Free Software
584 //Foundation. If the Program does not specify a version number of the
585 //GNU General Public License, you may choose any version ever published
586 //by the Free Software Foundation.
587 //
588 // If the Program specifies that a proxy can decide which future
589 //versions of the GNU General Public License can be used, that proxy's
590 //public statement of acceptance of a version permanently authorizes you
591 //to choose that version for the Program.
592 //
593 // Later license versions may give you additional or different
594 //permissions. However, no additional obligations are imposed on any
595 //author or copyright holder as a result of your choosing to follow a
596 //later version.
597 //
598 // 15. Disclaimer of Warranty.
599 //
600 // THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
601 //APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
602 //HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
603 //OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
604 //THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
605 //PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
606 //IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
607 //ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
608 //
609 // 16. Limitation of Liability.
610 //
611 // IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
612 //WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
613 //THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
614 //GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
615 //USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
616 //DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
617 //PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
618 //EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
619 //SUCH DAMAGES.
620 //
621 // 17. Interpretation of Sections 15 and 16.
622 //
623 // If the disclaimer of warranty and limitation of liability provided
624 //above cannot be given local legal effect according to their terms,
625 //reviewing courts shall apply local law that most closely approximates
626 //an absolute waiver of all civil liability in connection with the
627 //Program, unless a warranty or assumption of liability accompanies a
628 //copy of the Program in return for a fee.
629 //
630 // END OF TERMS AND CONDITIONS
631 //
632 // How to Apply These Terms to Your New Programs
633 //
634 // If you develop a new program, and you want it to be of the greatest
635 //possible use to the public, the best way to achieve this is to make it
636 //free software which everyone can redistribute and change under these terms.
637 //
638 // To do so, attach the following notices to the program. It is safest
639 //to attach them to the start of each source file to most effectively
640 //state the exclusion of warranty; and each file should have at least
641 //the "copyright" line and a pointer to where the full notice is found.
642 //
643 // <one line to give the program's name and a brief idea of what it does.>
644 // Copyright (C) <year> <name of author>

649 // (at your option) any later version.
650 //
651 // This program is distributed in the hope that it will be useful,
652 // but WITHOUT ANY WARRANTY; without even the implied warranty of

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