26 // GNU GENERAL PUBLIC LICENSE
27 // Version 3, 29 June 2007
28 //
29 // Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
30 // Everyone is permitted to copy and distribute verbatim copies
31 // of this license document, but changing it is not allowed.
32 //
33 // Preamble
34 //
35 // The GNU General Public License is a free, copyleft license for
36 //software and other kinds of works.
37 //
38 // The licenses for most software and other practical works are designed
39 //to take away your freedom to share and change the works. By contrast,
40 //the GNU General Public License is intended to guarantee your freedom to
41 //share and change all versions of a program--to make sure it remains free
42 //software for all its users. We, the Free Software Foundation, use the
43 //GNU General Public License for most of our software; it applies also to
44 //any other work released this way by its authors. You can apply it to
45 //your programs, too.
46 //
47 // When we speak of free software, we are referring to freedom, not
48 //price. Our General Public Licenses are designed to make sure that you
49 //have the freedom to distribute copies of free software (and charge for
50 //them if you wish), that you receive source code or can get it if you
51 //want it, that you can change the software or use pieces of it in new
52 //free programs, and that you know you can do these things.
53 //
54 // To protect your rights, we need to prevent others from denying you
55 //these rights or asking you to surrender the rights. Therefore, you have
56 //certain responsibilities if you distribute copies of the software, or if
57 //you modify it: responsibilities to respect the freedom of others.
58 //
59 // For example, if you distribute copies of such a program, whether
60 //gratis or for a fee, you must pass on to the recipients the same
61 //freedoms that you received. You must make sure that they, too, receive
62 //or can get the source code. And you must show them these terms so they
63 //know their rights.
64 //
65 // Developers that use the GNU GPL protect your rights with two steps:
66 //(1) assert copyright on the software, and (2) offer you this License
67 //giving you legal permission to copy, distribute and/or modify it.
68 //
69 // For the developers' and authors' protection, the GPL clearly explains
70 //that there is no warranty for this free software. For both users' and
71 //authors' sake, the GPL requires that modified versions be marked as
72 //changed, so that their problems will not be attributed erroneously to
73 //authors of previous versions.
74 //
75 // Some devices are designed to deny users access to install or run
76 //modified versions of the software inside them, although the manufacturer
77 //can do so. This is fundamentally incompatible with the aim of
78 //protecting users' freedom to change the software. The systematic
79 //pattern of such abuse occurs in the area of products for individuals to
80 //use, which is precisely where it is most unacceptable. Therefore, we
81 //have designed this version of the GPL to prohibit the practice for those
82 //products. If such problems arise substantially in other domains, we
83 //stand ready to extend this provision to those domains in future versions
84 //of the GPL, as needed to protect the freedom of users.
85 //
86 // Finally, every program is threatened constantly by software patents.
87 //States should not allow patents to restrict development and use of
88 //software on general-purpose computers, but in those that do, we wish to
89 //avoid the special danger that patents applied to a free program could
90 //make it effectively proprietary. To prevent this, the GPL assures that
91 //patents cannot be used to render the program non-free.
92 //
93 // The precise terms and conditions for copying, distribution and
94 //modification follow.
95 //
96 // TERMS AND CONDITIONS
97 //
98 // 0. Definitions.
99 //
100 // "This License" refers to version 3 of the GNU General Public License.
101 //
102 // "Copyright" also means copyright-like laws that apply to other kinds of
103 //works, such as semiconductor masks.
104 //
105 // "The Program" refers to any copyrightable work licensed under this
106 //License. Each licensee is addressed as "you". "Licensees" and
107 //"recipients" may be individuals or organizations.
108 //
109 // To "modify" a work means to copy from or adapt all or part of the work
110 //in a fashion requiring copyright permission, other than the making of an
111 //exact copy. The resulting work is called a "modified version" of the
112 //earlier work or a work "based on" the earlier work.
113 //
114 // A "covered work" means either the unmodified Program or a work based
115 //on the Program.
116 //
117 // To "propagate" a work means to do anything with it that, without
118 //permission, would make you directly or secondarily liable for
119 //infringement under applicable copyright law, except executing it on a
120 //computer or modifying a private copy. Propagation includes copying,
121 //distribution (with or without modification), making available to the
122 //public, and in some countries other activities as well.
123 //
124 // To "convey" a work means any kind of propagation that enables other
125 //parties to make or receive copies. Mere interaction with a user through
126 //a computer network, with no transfer of a copy, is not conveying.
127 //
128 // An interactive user interface displays "Appropriate Legal Notices"
129 //to the extent that it includes a convenient and prominently visible
130 //feature that (1) displays an appropriate copyright notice, and (2)
131 //tells the user that there is no warranty for the work (except to the
132 //extent that warranties are provided), that licensees may convey the
133 //work under this License, and how to view a copy of this License. If
134 //the interface presents a list of user commands or options, such as a
135 //menu, a prominent item in the list meets this criterion.
136 //
137 // 1. Source Code.
138 //
139 // The "source code" for a work means the preferred form of the work
140 //for making modifications to it. "Object code" means any non-source
141 //form of a work.
142 //
143 // A "Standard Interface" means an interface that either is an official
144 //standard defined by a recognized standards body, or, in the case of
145 //interfaces specified for a particular programming language, one that
146 //is widely used among developers working in that language.
147 //
148 // The "System Libraries" of an executable work include anything, other
149 //than the work as a whole, that (a) is included in the normal form of
150 //packaging a Major Component, but which is not part of that Major
151 //Component, and (b) serves only to enable use of the work with that
152 //Major Component, or to implement a Standard Interface for which an
153 //implementation is available to the public in source code form. A
154 //"Major Component", in this context, means a major essential component
155 //(kernel, window system, and so on) of the specific operating system
156 //(if any) on which the executable work runs, or a compiler used to
157 //produce the work, or an object code interpreter used to run it.
158 //
159 // The "Corresponding Source" for a work in object code form means all
160 //the source code needed to generate, install, and (for an executable
161 //work) run the object code and to modify the work, including scripts to
162 //control those activities. However, it does not include the work's
163 //System Libraries, or general-purpose tools or generally available free
164 //programs which are used unmodified in performing those activities but
165 //which are not part of the work. For example, Corresponding Source
166 //includes interface definition files associated with source files for
167 //the work, and the source code for shared libraries and dynamically
168 //linked subprograms that the work is specifically designed to require,
169 //such as by intimate data communication or control flow between those
170 //subprograms and other parts of the work.
171 //
172 // The Corresponding Source need not include anything that users
173 //can regenerate automatically from other parts of the Corresponding
174 //Source.
175 //
176 // The Corresponding Source for a work in source code form is that
177 //same work.
178 //
179 // 2. Basic Permissions.
180 //
181 // All rights granted under this License are granted for the term of
182 //copyright on the Program, and are irrevocable provided the stated
183 //conditions are met. This License explicitly affirms your unlimited
184 //permission to run the unmodified Program. The output from running a
185 //covered work is covered by this License only if the output, given its
186 //content, constitutes a covered work. This License acknowledges your
187 //rights of fair use or other equivalent, as provided by copyright law.
188 //
189 // You may make, run and propagate covered works that you do not
190 //convey, without conditions so long as your license otherwise remains
191 //in force. You may convey covered works to others for the sole purpose
192 //of having them make modifications exclusively for you, or provide you
193 //with facilities for running those works, provided that you comply with
194 //the terms of this License in conveying all material for which you do
195 //not control copyright. Those thus making or running the covered works
196 //for you must do so exclusively on your behalf, under your direction
197 //and control, on terms that prohibit them from making any copies of
198 //your copyrighted material outside their relationship with you.
199 //
200 // Conveying under any other circumstances is permitted solely under
201 //the conditions stated below. Sublicensing is not allowed; section 10
202 //makes it unnecessary.
203 //
204 // 3. Protecting Users' Legal Rights From Anti-Circumvention Law.
205 //
206 // No covered work shall be deemed part of an effective technological
207 //measure under any applicable law fulfilling obligations under article
208 //11 of the WIPO copyright treaty adopted on 20 December 1996, or
209 //similar laws prohibiting or restricting circumvention of such
210 //measures.
211 //
212 // When you convey a covered work, you waive any legal power to forbid
213 //circumvention of technological measures to the extent such circumvention
214 //is effected by exercising rights under this License with respect to
215 //the covered work, and you disclaim any intention to limit operation or
216 //modification of the work as a means of enforcing, against the work's
217 //users, your or third parties' legal rights to forbid circumvention of
218 //technological measures.
219 //
220 // 4. Conveying Verbatim Copies.
221 //
222 // You may convey verbatim copies of the Program's source code as you
223 //receive it, in any medium, provided that you conspicuously and
224 //appropriately publish on each copy an appropriate copyright notice;
225 //keep intact all notices stating that this License and any
226 //non-permissive terms added in accord with section 7 apply to the code;
227 //keep intact all notices of the absence of any warranty; and give all
228 //recipients a copy of this License along with the Program.
229 //
230 // You may charge any price or no price for each copy that you convey,
231 //and you may offer support or warranty protection for a fee.
232 //
233 // 5. Conveying Modified Source Versions.
234 //
235 // You may convey a work based on the Program, or the modifications to
236 //produce it from the Program, in the form of source code under the
237 //terms of section 4, provided that you also meet all of these conditions:
238 //
239 // a) The work must carry prominent notices stating that you modified
240 // it, and giving a relevant date.
241 //
242 // b) The work must carry prominent notices stating that it is
243 // released under this License and any conditions added under section
244 // 7. This requirement modifies the requirement in section 4 to
245 // "keep intact all notices".
246 //
247 // c) You must license the entire work, as a whole, under this
248 // License to anyone who comes into possession of a copy. This
249 // License will therefore apply, along with any applicable section 7
250 // additional terms, to the whole of the work, and all its parts,
251 // regardless of how they are packaged. This License gives no
252 // permission to license the work in any other way, but it does not
253 // invalidate such permission if you have separately received it.
254 //
255 // d) If the work has interactive user interfaces, each must display
256 // Appropriate Legal Notices; however, if the Program has interactive
257 // interfaces that do not display Appropriate Legal Notices, your
258 // work need not make them do so.
259 //
260 // A compilation of a covered work with other separate and independent
261 //works, which are not by their nature extensions of the covered work,
262 //and which are not combined with it such as to form a larger program,
263 //in or on a volume of a storage or distribution medium, is called an
264 //"aggregate" if the compilation and its resulting copyright are not
265 //used to limit the access or legal rights of the compilation's users
266 //beyond what the individual works permit. Inclusion of a covered work
267 //in an aggregate does not cause this License to apply to the other
268 //parts of the aggregate.
269 //
270 // 6. Conveying Non-Source Forms.
271 //
272 // You may convey a covered work in object code form under the terms
273 //of sections 4 and 5, provided that you also convey the
274 //machine-readable Corresponding Source under the terms of this License,
275 //in one of these ways:
276 //
277 // a) Convey the object code in, or embodied in, a physical product
278 // (including a physical distribution medium), accompanied by the
279 // Corresponding Source fixed on a durable physical medium
280 // customarily used for software interchange.
281 //
282 // b) Convey the object code in, or embodied in, a physical product
283 // (including a physical distribution medium), accompanied by a
284 // written offer, valid for at least three years and valid for as
285 // long as you offer spare parts or customer support for that product
286 // model, to give anyone who possesses the object code either (1) a
287 // copy of the Corresponding Source for all the software in the
288 // product that is covered by this License, on a durable physical
289 // medium customarily used for software interchange, for a price no
290 // more than your reasonable cost of physically performing this
291 // conveying of source, or (2) access to copy the
292 // Corresponding Source from a network server at no charge.
293 //
294 // c) Convey individual copies of the object code with a copy of the
295 // written offer to provide the Corresponding Source. This
296 // alternative is allowed only occasionally and noncommercially, and
297 // only if you received the object code with such an offer, in accord
298 // with subsection 6b.
299 //
300 // d) Convey the object code by offering access from a designated
301 // place (gratis or for a charge), and offer equivalent access to the
302 // Corresponding Source in the same way through the same place at no
303 // further charge. You need not require recipients to copy the
304 // Corresponding Source along with the object code. If the place to
305 // copy the object code is a network server, the Corresponding Source
306 // may be on a different server (operated by you or a third party)
307 // that supports equivalent copying facilities, provided you maintain
308 // clear directions next to the object code saying where to find the
309 // Corresponding Source. Regardless of what server hosts the
310 // Corresponding Source, you remain obligated to ensure that it is
311 // available for as long as needed to satisfy these requirements.
312 //
313 // e) Convey the object code using peer-to-peer transmission, provided
314 // you inform other peers where the object code and Corresponding
315 // Source of the work are being offered to the general public at no
316 // charge under subsection 6d.
317 //
318 // A separable portion of the object code, whose source code is excluded
319 //from the Corresponding Source as a System Library, need not be
320 //included in conveying the object code work.
321 //
322 // A "User Product" is either (1) a "consumer product", which means any
323 //tangible personal property which is normally used for personal, family,
324 //or household purposes, or (2) anything designed or sold for incorporation
325 //into a dwelling. In determining whether a product is a consumer product,
326 //doubtful cases shall be resolved in favor of coverage. For a particular
327 //product received by a particular user, "normally used" refers to a
328 //typical or common use of that class of product, regardless of the status
329 //of the particular user or of the way in which the particular user
330 //actually uses, or expects or is expected to use, the product. A product
331 //is a consumer product regardless of whether the product has substantial
332 //commercial, industrial or non-consumer uses, unless such uses represent
333 //the only significant mode of use of the product.
334 //
335 // "Installation Information" for a User Product means any methods,
336 //procedures, authorization keys, or other information required to install
337 //and execute modified versions of a covered work in that User Product from
338 //a modified version of its Corresponding Source. The information must
339 //suffice to ensure that the continued functioning of the modified object
340 //code is in no case prevented or interfered with solely because
341 //modification has been made.
342 //
343 // If you convey an object code work under this section in, or with, or
344 //specifically for use in, a User Product, and the conveying occurs as
345 //part of a transaction in which the right of possession and use of the
346 //User Product is transferred to the recipient in perpetuity or for a
347 //fixed term (regardless of how the transaction is characterized), the
348 //Corresponding Source conveyed under this section must be accompanied
349 //by the Installation Information. But this requirement does not apply
350 //if neither you nor any third party retains the ability to install
351 //modified object code on the User Product (for example, the work has
352 //been installed in ROM).
353 //
354 // The requirement to provide Installation Information does not include a
355 //requirement to continue to provide support service, warranty, or updates
356 //for a work that has been modified or installed by the recipient, or for
357 //the User Product in which it has been modified or installed. Access to a
358 //network may be denied when the modification itself materially and
359 //adversely affects the operation of the network or violates the rules and
360 //protocols for communication across the network.
361 //
362 // Corresponding Source conveyed, and Installation Information provided,
363 //in accord with this section must be in a format that is publicly
364 //documented (and with an implementation available to the public in
365 //source code form), and must require no special password or key for
366 //unpacking, reading or copying.
367 //
368 // 7. Additional Terms.
369 //
370 // "Additional permissions" are terms that supplement the terms of this
371 //License by making exceptions from one or more of its conditions.
372 //Additional permissions that are applicable to the entire Program shall
373 //be treated as though they were included in this License, to the extent
374 //that they are valid under applicable law. If additional permissions
375 //apply only to part of the Program, that part may be used separately
376 //under those permissions, but the entire Program remains governed by
377 //this License without regard to the additional permissions.
378 //
379 // When you convey a copy of a covered work, you may at your option
380 //remove any additional permissions from that copy, or from any part of
381 //it. (Additional permissions may be written to require their own
382 //removal in certain cases when you modify the work.) You may place
383 //additional permissions on material, added by you to a covered work,
384 //for which you have or can give appropriate copyright permission.
385 //
386 // Notwithstanding any other provision of this License, for material you
387 //add to a covered work, you may (if authorized by the copyright holders of
388 //that material) supplement the terms of this License with terms:
389 //
390 // a) Disclaiming warranty or limiting liability differently from the
391 // terms of sections 15 and 16 of this License; or
392 //
393 // b) Requiring preservation of specified reasonable legal notices or
394 // author attributions in that material or in the Appropriate Legal
395 // Notices displayed by works containing it; or
396 //
397 // c) Prohibiting misrepresentation of the origin of that material, or
398 // requiring that modified versions of such material be marked in
399 // reasonable ways as different from the original version; or
400 //
401 // d) Limiting the use for publicity purposes of names of licensors or
402 // authors of the material; or
403 //
404 // e) Declining to grant rights under trademark law for use of some
405 // trade names, trademarks, or service marks; or
406 //
407 // f) Requiring indemnification of licensors and authors of that
408 // material by anyone who conveys the material (or modified versions of
409 // it) with contractual assumptions of liability to the recipient, for
410 // any liability that these contractual assumptions directly impose on
411 // those licensors and authors.
412 //
413 // All other non-permissive additional terms are considered "further
414 //restrictions" within the meaning of section 10. If the Program as you
415 //received it, or any part of it, contains a notice stating that it is
416 //governed by this License along with a term that is a further
417 //restriction, you may remove that term. If a license document contains
418 //a further restriction but permits relicensing or conveying under this
419 //License, you may add to a covered work material governed by the terms
420 //of that license document, provided that the further restriction does
421 //not survive such relicensing or conveying.
422 //
423 // If you add terms to a covered work in accord with this section, you
424 //must place, in the relevant source files, a statement of the
425 //additional terms that apply to those files, or a notice indicating
426 //where to find the applicable terms.
427 //
428 // Additional terms, permissive or non-permissive, may be stated in the
429 //form of a separately written license, or stated as exceptions;
430 //the above requirements apply either way.
431 //
432 // 8. Termination.
433 //
434 // You may not propagate or modify a covered work except as expressly
435 //provided under this License. Any attempt otherwise to propagate or
436 //modify it is void, and will automatically terminate your rights under
437 //this License (including any patent licenses granted under the third
438 //paragraph of section 11).
439 //
440 // However, if you cease all violation of this License, then your
441 //license from a particular copyright holder is reinstated (a)
442 //provisionally, unless and until the copyright holder explicitly and
443 //finally terminates your license, and (b) permanently, if the copyright
444 //holder fails to notify you of the violation by some reasonable means
445 //prior to 60 days after the cessation.
446 //
447 // Moreover, your license from a particular copyright holder is
448 //reinstated permanently if the copyright holder notifies you of the
449 //violation by some reasonable means, this is the first time you have
450 //received notice of violation of this License (for any work) from that
451 //copyright holder, and you cure the violation prior to 30 days after
452 //your receipt of the notice.
453 //
454 // Termination of your rights under this section does not terminate the
455 //licenses of parties who have received copies or rights from you under
456 //this License. If your rights have been terminated and not permanently
457 //reinstated, you do not qualify to receive new licenses for the same
458 //material under section 10.
459 //
460 // 9. Acceptance Not Required for Having Copies.
461 //
462 // You are not required to accept this License in order to receive or
463 //run a copy of the Program. Ancillary propagation of a covered work
464 //occurring solely as a consequence of using peer-to-peer transmission
465 //to receive a copy likewise does not require acceptance. However,
466 //nothing other than this License grants you permission to propagate or
467 //modify any covered work. These actions infringe copyright if you do
468 //not accept this License. Therefore, by modifying or propagating a
469 //covered work, you indicate your acceptance of this License to do so.
470 //
471 // 10. Automatic Licensing of Downstream Recipients.
472 //
473 // Each time you convey a covered work, the recipient automatically
474 //receives a license from the original licensors, to run, modify and
475 //propagate that work, subject to this License. You are not responsible
476 //for enforcing compliance by third parties with this License.
477 //
478 // An "entity transaction" is a transaction transferring control of an
479 //organization, or substantially all assets of one, or subdividing an
480 //organization, or merging organizations. If propagation of a covered
481 //work results from an entity transaction, each party to that
482 //transaction who receives a copy of the work also receives whatever
483 //licenses to the work the party's predecessor in interest had or could
484 //give under the previous paragraph, plus a right to possession of the
485 //Corresponding Source of the work from the predecessor in interest, if
486 //the predecessor has it or can get it with reasonable efforts.
487 //
488 // You may not impose any further restrictions on the exercise of the
489 //rights granted or affirmed under this License. For example, you may
490 //not impose a license fee, royalty, or other charge for exercise of
491 //rights granted under this License, and you may not initiate litigation
492 //(including a cross-claim or counterclaim in a lawsuit) alleging that
493 //any patent claim is infringed by making, using, selling, offering for
494 //sale, or importing the Program or any portion of it.
495 //
496 // 11. Patents.
497 //
498 // A "contributor" is a copyright holder who authorizes use under this
499 //License of the Program or a work on which the Program is based. The
500 //work thus licensed is called the contributor's "contributor version".
501 //
502 // A contributor's "essential patent claims" are all patent claims
503 //owned or controlled by the contributor, whether already acquired or
504 //hereafter acquired, that would be infringed by some manner, permitted
505 //by this License, of making, using, or selling its contributor version,
506 //but do not include claims that would be infringed only as a
507 //consequence of further modification of the contributor version. For
508 //purposes of this definition, "control" includes the right to grant
509 //patent sublicenses in a manner consistent with the requirements of
510 //this License.
511 //
512 // Each contributor grants you a non-exclusive, worldwide, royalty-free
513 //patent license under the contributor's essential patent claims, to
514 //make, use, sell, offer for sale, import and otherwise run, modify and
515 //propagate the contents of its contributor version.
516 //
517 // In the following three paragraphs, a "patent license" is any express
518 //agreement or commitment, however denominated, not to enforce a patent
519 //(such as an express permission to practice a patent or covenant not to
520 //sue for patent infringement). To "grant" such a patent license to a
521 //party means to make such an agreement or commitment not to enforce a
522 //patent against the party.
523 //
524 // If you convey a covered work, knowingly relying on a patent license,
525 //and the Corresponding Source of the work is not available for anyone
526 //to copy, free of charge and under the terms of this License, through a
527 //publicly available network server or other readily accessible means,
528 //then you must either (1) cause the Corresponding Source to be so
529 //available, or (2) arrange to deprive yourself of the benefit of the
530 //patent license for this particular work, or (3) arrange, in a manner
531 //consistent with the requirements of this License, to extend the patent
532 //license to downstream recipients. "Knowingly relying" means you have
533 //actual knowledge that, but for the patent license, your conveying the
534 //covered work in a country, or your recipient's use of the covered work
535 //in a country, would infringe one or more identifiable patents in that
536 //country that you have reason to believe are valid.
537 //
538 // If, pursuant to or in connection with a single transaction or
539 //arrangement, you convey, or propagate by procuring conveyance of, a
540 //covered work, and grant a patent license to some of the parties
541 //receiving the covered work authorizing them to use, propagate, modify
542 //or convey a specific copy of the covered work, then the patent license
543 //you grant is automatically extended to all recipients of the covered
544 //work and works based on it.
545 //
546 // A patent license is "discriminatory" if it does not include within
547 //the scope of its coverage, prohibits the exercise of, or is
548 //conditioned on the non-exercise of one or more of the rights that are
549 //specifically granted under this License. You may not convey a covered
550 //work if you are a party to an arrangement with a third party that is
551 //in the business of distributing software, under which you make payment
552 //to the third party based on the extent of your activity of conveying
553 //the work, and under which the third party grants, to any of the
554 //parties who would receive the covered work from you, a discriminatory
555 //patent license (a) in connection with copies of the covered work
556 //conveyed by you (or copies made from those copies), or (b) primarily
557 //for and in connection with specific products or compilations that
558 //contain the covered work, unless you entered into that arrangement,
559 //or that patent license was granted, prior to 28 March 2007.
560 //
561 // Nothing in this License shall be construed as excluding or limiting
562 //any implied license or other defenses to infringement that may
563 //otherwise be available to you under applicable patent law.
564 //
565 // 12. No Surrender of Others' Freedom.
566 //
567 // If conditions are imposed on you (whether by court order, agreement or
568 //otherwise) that contradict the conditions of this License, they do not
569 //excuse you from the conditions of this License. If you cannot convey a
570 //covered work so as to satisfy simultaneously your obligations under this
571 //License and any other pertinent obligations, then as a consequence you may
572 //not convey it at all. For example, if you agree to terms that obligate you
573 //to collect a royalty for further conveying from those to whom you convey
574 //the Program, the only way you could satisfy both those terms and this
575 //License would be to refrain entirely from conveying the Program.
576 //
577 // 13. Use with the GNU Affero General Public License.
578 //
579 // Notwithstanding any other provision of this License, you have
580 //permission to link or combine any covered work with a work licensed
581 //under version 3 of the GNU Affero General Public License into a single
582 //combined work, and to convey the resulting work. The terms of this
583 //License will continue to apply to the part which is the covered work,
584 //but the special requirements of the GNU Affero General Public License,
585 //section 13, concerning interaction through a network will apply to the
586 //combination as such.
587 //
588 // 14. Revised Versions of this License.
589 //
590 // The Free Software Foundation may publish revised and/or new versions of
591 //the GNU General Public License from time to time. Such new versions will
592 //be similar in spirit to the present version, but may differ in detail to
593 //address new problems or concerns.
594 //
595 // Each version is given a distinguishing version number. If the
596 //Program specifies that a certain numbered version of the GNU General
597 //Public License "or any later version" applies to it, you have the
598 //option of following the terms and conditions either of that numbered
599 //version or of any later version published by the Free Software
600 //Foundation. If the Program does not specify a version number of the
601 //GNU General Public License, you may choose any version ever published
602 //by the Free Software Foundation.
603 //
604 // If the Program specifies that a proxy can decide which future
605 //versions of the GNU General Public License can be used, that proxy's
606 //public statement of acceptance of a version permanently authorizes you
607 //to choose that version for the Program.
608 //
609 // Later license versions may give you additional or different
610 //permissions. However, no additional obligations are imposed on any
611 //author or copyright holder as a result of your choosing to follow a
612 //later version.
613 //
614 // 15. Disclaimer of Warranty.
615 //
616 // THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
617 //APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
618 //HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
619 //OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
620 //THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
621 //PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
622 //IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
623 //ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
624 //
625 // 16. Limitation of Liability.
626 //
627 // IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
628 //WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
629 //THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
630 //GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
631 //USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
632 //DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
633 //PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
634 //EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
635 //SUCH DAMAGES.
636 //
637 // 17. Interpretation of Sections 15 and 16.
638 //
639 // If the disclaimer of warranty and limitation of liability provided
640 //above cannot be given local legal effect according to their terms,
641 //reviewing courts shall apply local law that most closely approximates
642 //an absolute waiver of all civil liability in connection with the
643 //Program, unless a warranty or assumption of liability accompanies a
644 //copy of the Program in return for a fee.
645 //
646 // END OF TERMS AND CONDITIONS
647 //
648 // How to Apply These Terms to Your New Programs
649 //
650 // If you develop a new program, and you want it to be of the greatest
651 //possible use to the public, the best way to achieve this is to make it
652 //free software which everyone can redistribute and change under these terms.
653 //
654 // To do so, attach the following notices to the program. It is safest
655 //to attach them to the start of each source file to most effectively
656 //state the exclusion of warranty; and each file should have at least
657 //the "copyright" line and a pointer to where the full notice is found.

719 // action_in

721 // "A" : Add new.
722 // "M" : Modify existing.
723 //
724 // rec_in
725 // The data about the record to add or modify, as an associative array.
726 //
727 // Adding a record:
728 // a)The index must be absent (it is assigned automatically by the database).
729 // b)The userid must be included and must be globally unique, otherwise an error will be
730 // returned and the record won't be added.
731 // c)Fields out of range or defective will be corrected, and warnings will be returned.
732 // The record will, however, be added if possible.
733 // c)All fields not present in the associative array will be assigned default values.
734 // d)The creation/modification SGUID is handled automatically and may not be included in the
735 // associative array.
736 //
737 // Modifying a record:
738 // a)The record is specified by either index or userid. If both are specified, they must
739 // correspond to an existing record and must be consistent.
740 // b)Fields not included in the associative array are not touched.
741 // c)The creation/modification SGUID is handled automatically. If this field is included
742 // in the associative array, it means to check this against what is in the database
743 // and error out on editing collision if the value doesn't match what is in the database.

745 //Outputs
746 // result_code_out
747 // Adding a record:
748 // 0 if the operation failed, or the index if it succeeded.
