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