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.

967     // Adding a record:
968     // a)The index must be absent (it is assigned automatically by the database).
969     // b)The userid must be included and must be globally unique, otherwise an error will be
970     // returned and the record won't be added.

973     // c)All fields not present in the associative array will be assigned default values.
974     // d)The creation/modification SGUID is handled automatically and may not be included in the
975     // associative array.
976     //
977     // Modifying a record:
978     // a)The record is specified by either index or userid. If both are specified, they must
979     // correspond to an existing record and must be consistent.
980     // b)Fields not included in the associative array are not touched.
