7 Everyone is permitted to copy and distribute verbatim copies
8 of this license document, but changing it is not allowed.
13 The purpose of this License is to make a manual, textbook, or other
14 functional and useful document "free" in the sense of freedom: to
15 assure everyone the effective freedom to copy and redistribute it,
16 with or without modifying it, either commercially or noncommercially.
17 Secondarily, this License preserves for the author and publisher a way
18 to get credit for their work, while not being considered responsible
19 for modifications made by others.
21 This License is a kind of "copyleft", which means that derivative
22 works of the document must themselves be free in the same sense. It
23 complements the GNU General Public License, which is a copyleft
24 license designed for free software.
26 We have designed this License in order to use it for manuals for free
27 software, because free software needs free documentation: a free
28 program should come with manuals providing the same freedoms that the
29 software does. But this License is not limited to software manuals;
30 it can be used for any textual work, regardless of subject matter or
31 whether it is published as a printed book. We recommend this License
32 principally for works whose purpose is instruction or reference.
35 1. APPLICABILITY AND DEFINITIONS
37 This License applies to any manual or other work, in any medium, that
38 contains a notice placed by the copyright holder saying it can be
39 distributed under the terms of this License. Such a notice grants a
40 world-wide, royalty-free license, unlimited in duration, to use that
41 work under the conditions stated herein. The "Document", below,
42 refers to any such manual or work. Any member of the public is a
43 licensee, and is addressed as "you". You accept the license if you
44 copy, modify or distribute the work in a way requiring permission
47 A "Modified Version" of the Document means any work containing the
48 Document or a portion of it, either copied verbatim, or with
49 modifications and/or translated into another language.
51 A "Secondary Section" is a named appendix or a front-matter section of
52 the Document that deals exclusively with the relationship of the
53 publishers or authors of the Document to the Document's overall subject
54 (or to related matters) and contains nothing that could fall directly
55 within that overall subject. (Thus, if the Document is in part a
56 textbook of mathematics, a Secondary Section may not explain any
57 mathematics.) The relationship could be a matter of historical
58 connection with the subject or with related matters, or of legal,
59 commercial, philosophical, ethical or political position regarding
62 The "Invariant Sections" are certain Secondary Sections whose titles
63 are designated, as being those of Invariant Sections, in the notice
64 that says that the Document is released under this License. If a
65 section does not fit the above definition of Secondary then it is not
66 allowed to be designated as Invariant. The Document may contain zero
67 Invariant Sections. If the Document does not identify any Invariant
68 Sections then there are none.
70 The "Cover Texts" are certain short passages of text that are listed,
71 as Front-Cover Texts or Back-Cover Texts, in the notice that says that
72 the Document is released under this License. A Front-Cover Text may
73 be at most 5 words, and a Back-Cover Text may be at most 25 words.
75 A "Transparent" copy of the Document means a machine-readable copy,
76 represented in a format whose specification is available to the
77 general public, that is suitable for revising the document
78 straightforwardly with generic text editors or (for images composed of
79 pixels) generic paint programs or (for drawings) some widely available
80 drawing editor, and that is suitable for input to text formatters or
81 for automatic translation to a variety of formats suitable for input
82 to text formatters. A copy made in an otherwise Transparent file
83 format whose markup, or absence of markup, has been arranged to thwart
84 or discourage subsequent modification by readers is not Transparent.
85 An image format is not Transparent if used for any substantial amount
86 of text. A copy that is not "Transparent" is called "Opaque".
88 Examples of suitable formats for Transparent copies include plain
89 ASCII without markup, Texinfo input format, LaTeX input format, SGML
90 or XML using a publicly available DTD, and standard-conforming simple
91 HTML, PostScript or PDF designed for human modification. Examples of
92 transparent image formats include PNG, XCF and JPG. Opaque formats
93 include proprietary formats that can be read and edited only by
94 proprietary word processors, SGML or XML for which the DTD and/or
95 processing tools are not generally available, and the
96 machine-generated HTML, PostScript or PDF produced by some word
97 processors for output purposes only.
99 The "Title Page" means, for a printed book, the title page itself,
100 plus such following pages as are needed to hold, legibly, the material
101 this License requires to appear in the title page. For works in
102 formats which do not have any title page as such, "Title Page" means
103 the text near the most prominent appearance of the work's title,
104 preceding the beginning of the body of the text.
106 A section "Entitled XYZ" means a named subunit of the Document whose
107 title either is precisely XYZ or contains XYZ in parentheses following
108 text that translates XYZ in another language. (Here XYZ stands for a
109 specific section name mentioned below, such as "Acknowledgements",
110 "Dedications", "Endorsements", or "History".) To "Preserve the Title"
111 of such a section when you modify the Document means that it remains a
112 section "Entitled XYZ" according to this definition.
114 The Document may include Warranty Disclaimers next to the notice which
115 states that this License applies to the Document. These Warranty
116 Disclaimers are considered to be included by reference in this
117 License, but only as regards disclaiming warranties: any other
118 implication that these Warranty Disclaimers may have is void and has
119 no effect on the meaning of this License.
124 You may copy and distribute the Document in any medium, either
125 commercially or noncommercially, provided that this License, the
126 copyright notices, and the license notice saying this License applies
127 to the Document are reproduced in all copies, and that you add no other
128 conditions whatsoever to those of this License. You may not use
129 technical measures to obstruct or control the reading or further
130 copying of the copies you make or distribute. However, you may accept
131 compensation in exchange for copies. If you distribute a large enough
132 number of copies you must also follow the conditions in section 3.
134 You may also lend copies, under the same conditions stated above, and
135 you may publicly display copies.
138 3. COPYING IN QUANTITY
140 If you publish printed copies (or copies in media that commonly have
141 printed covers) of the Document, numbering more than 100, and the
142 Document's license notice requires Cover Texts, you must enclose the
143 copies in covers that carry, clearly and legibly, all these Cover
144 Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on
145 the back cover. Both covers must also clearly and legibly identify
146 you as the publisher of these copies. The front cover must present
147 the full title with all words of the title equally prominent and
148 visible. You may add other material on the covers in addition.
149 Copying with changes limited to the covers, as long as they preserve
150 the title of the Document and satisfy these conditions, can be treated
151 as verbatim copying in other respects.
153 If the required texts for either cover are too voluminous to fit
154 legibly, you should put the first ones listed (as many as fit
155 reasonably) on the actual cover, and continue the rest onto adjacent
158 If you publish or distribute Opaque copies of the Document numbering
159 more than 100, you must either include a machine-readable Transparent
160 copy along with each Opaque copy, or state in or with each Opaque copy
161 a computer-network location from which the general network-using
162 public has access to download using public-standard network protocols
163 a complete Transparent copy of the Document, free of added material.
164 If you use the latter option, you must take reasonably prudent steps,
165 when you begin distribution of Opaque copies in quantity, to ensure
166 that this Transparent copy will remain thus accessible at the stated
167 location until at least one year after the last time you distribute an
168 Opaque copy (directly or through your agents or retailers) of that
169 edition to the public.
171 It is requested, but not required, that you contact the authors of the
172 Document well before redistributing any large number of copies, to give
173 them a chance to provide you with an updated version of the Document.
178 You may copy and distribute a Modified Version of the Document under
179 the conditions of sections 2 and 3 above, provided that you release
180 the Modified Version under precisely this License, with the Modified
181 Version filling the role of the Document, thus licensing distribution
182 and modification of the Modified Version to whoever possesses a copy
183 of it. In addition, you must do these things in the Modified Version:
185 A. Use in the Title Page (and on the covers, if any) a title distinct
186 from that of the Document, and from those of previous versions
187 (which should, if there were any, be listed in the History section
188 of the Document). You may use the same title as a previous version
189 if the original publisher of that version gives permission.
190 B. List on the Title Page, as authors, one or more persons or entities
191 responsible for authorship of the modifications in the Modified
192 Version, together with at least five of the principal authors of the
193 Document (all of its principal authors, if it has fewer than five),
194 unless they release you from this requirement.
195 C. State on the Title page the name of the publisher of the
196 Modified Version, as the publisher.
197 D. Preserve all the copyright notices of the Document.
198 E. Add an appropriate copyright notice for your modifications
199 adjacent to the other copyright notices.
200 F. Include, immediately after the copyright notices, a license notice
201 giving the public permission to use the Modified Version under the
202 terms of this License, in the form shown in the Addendum below.
203 G. Preserve in that license notice the full lists of Invariant Sections
204 and required Cover Texts given in the Document's license notice.
205 H. Include an unaltered copy of this License.
206 I. Preserve the section Entitled "History", Preserve its Title, and add
207 to it an item stating at least the title, year, new authors, and
208 publisher of the Modified Version as given on the Title Page. If
209 there is no section Entitled "History" in the Document, create one
210 stating the title, year, authors, and publisher of the Document as
211 given on its Title Page, then add an item describing the Modified
212 Version as stated in the previous sentence.
213 J. Preserve the network location, if any, given in the Document for
214 public access to a Transparent copy of the Document, and likewise
215 the network locations given in the Document for previous versions
216 it was based on. These may be placed in the "History" section.
217 You may omit a network location for a work that was published at
218 least four years before the Document itself, or if the original
219 publisher of the version it refers to gives permission.
220 K. For any section Entitled "Acknowledgements" or "Dedications",
221 Preserve the Title of the section, and preserve in the section all
222 the substance and tone of each of the contributor acknowledgements
223 and/or dedications given therein.
224 L. Preserve all the Invariant Sections of the Document,
225 unaltered in their text and in their titles. Section numbers
226 or the equivalent are not considered part of the section titles.
227 M. Delete any section Entitled "Endorsements". Such a section
228 may not be included in the Modified Version.
229 N. Do not retitle any existing section to be Entitled "Endorsements"
230 or to conflict in title with any Invariant Section.
231 O. Preserve any Warranty Disclaimers.
233 If the Modified Version includes new front-matter sections or
234 appendices that qualify as Secondary Sections and contain no material
235 copied from the Document, you may at your option designate some or all
236 of these sections as invariant. To do this, add their titles to the
237 list of Invariant Sections in the Modified Version's license notice.
238 These titles must be distinct from any other section titles.
240 You may add a section Entitled "Endorsements", provided it contains
241 nothing but endorsements of your Modified Version by various
242 parties--for example, statements of peer review or that the text has
243 been approved by an organization as the authoritative definition of a
246 You may add a passage of up to five words as a Front-Cover Text, and a
247 passage of up to 25 words as a Back-Cover Text, to the end of the list
248 of Cover Texts in the Modified Version. Only one passage of
249 Front-Cover Text and one of Back-Cover Text may be added by (or
250 through arrangements made by) any one entity. If the Document already
251 includes a cover text for the same cover, previously added by you or
252 by arrangement made by the same entity you are acting on behalf of,
253 you may not add another; but you may replace the old one, on explicit
254 permission from the previous publisher that added the old one.
256 The author(s) and publisher(s) of the Document do not by this License
257 give permission to use their names for publicity for or to assert or
258 imply endorsement of any Modified Version.
261 5. COMBINING DOCUMENTS
263 You may combine the Document with other documents released under this
264 License, under the terms defined in section 4 above for modified
265 versions, provided that you include in the combination all of the
266 Invariant Sections of all of the original documents, unmodified, and
267 list them all as Invariant Sections of your combined work in its
268 license notice, and that you preserve all their Warranty Disclaimers.
270 The combined work need only contain one copy of this License, and
271 multiple identical Invariant Sections may be replaced with a single
272 copy. If there are multiple Invariant Sections with the same name but
273 different contents, make the title of each such section unique by
274 adding at the end of it, in parentheses, the name of the original
275 author or publisher of that section if known, or else a unique number.
276 Make the same adjustment to the section titles in the list of
277 Invariant Sections in the license notice of the combined work.
279 In the combination, you must combine any sections Entitled "History"
280 in the various original documents, forming one section Entitled
281 "History"; likewise combine any sections Entitled "Acknowledgements",
282 and any sections Entitled "Dedications". You must delete all sections
283 Entitled "Endorsements".
286 6. COLLECTIONS OF DOCUMENTS
288 You may make a collection consisting of the Document and other documents
289 released under this License, and replace the individual copies of this
290 License in the various documents with a single copy that is included in
291 the collection, provided that you follow the rules of this License for
292 verbatim copying of each of the documents in all other respects.
294 You may extract a single document from such a collection, and distribute
295 it individually under this License, provided you insert a copy of this
296 License into the extracted document, and follow this License in all
297 other respects regarding verbatim copying of that document.
300 7. AGGREGATION WITH INDEPENDENT WORKS
302 A compilation of the Document or its derivatives with other separate
303 and independent documents or works, in or on a volume of a storage or
304 distribution medium, is called an "aggregate" if the copyright
305 resulting from the compilation is not used to limit the legal rights
306 of the compilation's users beyond what the individual works permit.
307 When the Document is included in an aggregate, this License does not
308 apply to the other works in the aggregate which are not themselves
309 derivative works of the Document.
311 If the Cover Text requirement of section 3 is applicable to these
312 copies of the Document, then if the Document is less than one half of
313 the entire aggregate, the Document's Cover Texts may be placed on
314 covers that bracket the Document within the aggregate, or the
315 electronic equivalent of covers if the Document is in electronic form.
316 Otherwise they must appear on printed covers that bracket the whole
322 Translation is considered a kind of modification, so you may
323 distribute translations of the Document under the terms of section 4.
324 Replacing Invariant Sections with translations requires special
325 permission from their copyright holders, but you may include
326 translations of some or all Invariant Sections in addition to the
327 original versions of these Invariant Sections. You may include a
328 translation of this License, and all the license notices in the
329 Document, and any Warranty Disclaimers, provided that you also include
330 the original English version of this License and the original versions
331 of those notices and disclaimers. In case of a disagreement between
332 the translation and the original version of this License or a notice
333 or disclaimer, the original version will prevail.
335 If a section in the Document is Entitled "Acknowledgements",
336 "Dedications", or "History", the requirement (section 4) to Preserve
337 its Title (section 1) will typically require changing the actual
343 You may not copy, modify, sublicense, or distribute the Document except
344 as expressly provided for under this License. Any other attempt to
345 copy, modify, sublicense or distribute the Document is void, and will
346 automatically terminate your rights under this License. However,
347 parties who have received copies, or rights, from you under this
348 License will not have their licenses terminated so long as such
349 parties remain in full compliance.
352 10. FUTURE REVISIONS OF THIS LICENSE
354 The Free Software Foundation may publish new, revised versions
355 of the GNU Free Documentation License from time to time. Such new
356 versions will be similar in spirit to the present version, but may
357 differ in detail to address new problems or concerns. See
358 http://www.gnu.org/copyleft/.
360 Each version of the License is given a distinguishing version number.
361 If the Document specifies that a particular numbered version of this
362 License "or any later version" applies to it, you have the option of
363 following the terms and conditions either of that specified version or
364 of any later version that has been published (not as a draft) by the
365 Free Software Foundation. If the Document does not specify a version
366 number of this License, you may choose any version ever published (not
367 as a draft) by the Free Software Foundation.
370 ADDENDUM: How to use this License for your documents
372 To use this License in a document you have written, include a copy of
373 the License in the document and put the following copyright and
374 license notices just after the title page:
376 Copyright (c) YEAR YOUR NAME.
377 Permission is granted to copy, distribute and/or modify this document
378 under the terms of the GNU Free Documentation License, Version 1.2
379 or any later version published by the Free Software Foundation;
380 with no Invariant Sections, no Front-Cover Texts, and no Back-Cover Texts.
381 A copy of the license is included in the section entitled "GNU
382 Free Documentation License".
384 If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts,
385 replace the "with...Texts." line with this:
387 with the Invariant Sections being LIST THEIR TITLES, with the
388 Front-Cover Texts being LIST, and with the Back-Cover Texts being LIST.
390 If you have Invariant Sections without Cover Texts, or some other
391 combination of the three, merge those two alternatives to suit the
394 If your document contains nontrivial examples of program code, we
395 recommend releasing these examples in parallel under your choice of
396 free software license, such as the GNU General Public License,
397 to permit their use in free software.
398 GNU GENERAL PUBLIC LICENSE
401 Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
402 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
403 Everyone is permitted to copy and distribute verbatim copies
404 of this license document, but changing it is not allowed.
408 The licenses for most software are designed to take away your
409 freedom to share and change it. By contrast, the GNU General Public
410 License is intended to guarantee your freedom to share and change free
411 software--to make sure the software is free for all its users. This
412 General Public License applies to most of the Free Software
413 Foundation's software and to any other program whose authors commit to
414 using it. (Some other Free Software Foundation software is covered by
415 the GNU Lesser General Public License instead.) You can apply it to
418 When we speak of free software, we are referring to freedom, not
419 price. Our General Public Licenses are designed to make sure that you
420 have the freedom to distribute copies of free software (and charge for
421 this service if you wish), that you receive source code or can get it
422 if you want it, that you can change the software or use pieces of it
423 in new free programs; and that you know you can do these things.
425 To protect your rights, we need to make restrictions that forbid
426 anyone to deny you these rights or to ask you to surrender the rights.
427 These restrictions translate to certain responsibilities for you if you
428 distribute copies of the software, or if you modify it.
430 For example, if you distribute copies of such a program, whether
431 gratis or for a fee, you must give the recipients all the rights that
432 you have. You must make sure that they, too, receive or can get the
433 source code. And you must show them these terms so they know their
436 We protect your rights with two steps: (1) copyright the software, and
437 (2) offer you this license which gives you legal permission to copy,
438 distribute and/or modify the software.
440 Also, for each author's protection and ours, we want to make certain
441 that everyone understands that there is no warranty for this free
442 software. If the software is modified by someone else and passed on, we
443 want its recipients to know that what they have is not the original, so
444 that any problems introduced by others will not reflect on the original
445 authors' reputations.
447 Finally, any free program is threatened constantly by software
448 patents. We wish to avoid the danger that redistributors of a free
449 program will individually obtain patent licenses, in effect making the
450 program proprietary. To prevent this, we have made it clear that any
451 patent must be licensed for everyone's free use or not licensed at all.
453 The precise terms and conditions for copying, distribution and
456 GNU GENERAL PUBLIC LICENSE
457 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
459 0. This License applies to any program or other work which contains
460 a notice placed by the copyright holder saying it may be distributed
461 under the terms of this General Public License. The "Program", below,
462 refers to any such program or work, and a "work based on the Program"
463 means either the Program or any derivative work under copyright law:
464 that is to say, a work containing the Program or a portion of it,
465 either verbatim or with modifications and/or translated into another
466 language. (Hereinafter, translation is included without limitation in
467 the term "modification".) Each licensee is addressed as "you".
469 Activities other than copying, distribution and modification are not
470 covered by this License; they are outside its scope. The act of
471 running the Program is not restricted, and the output from the Program
472 is covered only if its contents constitute a work based on the
473 Program (independent of having been made by running the Program).
474 Whether that is true depends on what the Program does.
476 1. You may copy and distribute verbatim copies of the Program's
477 source code as you receive it, in any medium, provided that you
478 conspicuously and appropriately publish on each copy an appropriate
479 copyright notice and disclaimer of warranty; keep intact all the
480 notices that refer to this License and to the absence of any warranty;
481 and give any other recipients of the Program a copy of this License
482 along with the Program.
484 You may charge a fee for the physical act of transferring a copy, and
485 you may at your option offer warranty protection in exchange for a fee.
487 2. You may modify your copy or copies of the Program or any portion
488 of it, thus forming a work based on the Program, and copy and
489 distribute such modifications or work under the terms of Section 1
490 above, provided that you also meet all of these conditions:
492 a) You must cause the modified files to carry prominent notices
493 stating that you changed the files and the date of any change.
495 b) You must cause any work that you distribute or publish, that in
496 whole or in part contains or is derived from the Program or any
497 part thereof, to be licensed as a whole at no charge to all third
498 parties under the terms of this License.
500 c) If the modified program normally reads commands interactively
501 when run, you must cause it, when started running for such
502 interactive use in the most ordinary way, to print or display an
503 announcement including an appropriate copyright notice and a
504 notice that there is no warranty (or else, saying that you provide
505 a warranty) and that users may redistribute the program under
506 these conditions, and telling the user how to view a copy of this
507 License. (Exception: if the Program itself is interactive but
508 does not normally print such an announcement, your work based on
509 the Program is not required to print an announcement.)
511 These requirements apply to the modified work as a whole. If
512 identifiable sections of that work are not derived from the Program,
513 and can be reasonably considered independent and separate works in
514 themselves, then this License, and its terms, do not apply to those
515 sections when you distribute them as separate works. But when you
516 distribute the same sections as part of a whole which is a work based
517 on the Program, the distribution of the whole must be on the terms of
518 this License, whose permissions for other licensees extend to the
519 entire whole, and thus to each and every part regardless of who wrote it.
521 Thus, it is not the intent of this section to claim rights or contest
522 your rights to work written entirely by you; rather, the intent is to
523 exercise the right to control the distribution of derivative or
524 collective works based on the Program.
526 In addition, mere aggregation of another work not based on the Program
527 with the Program (or with a work based on the Program) on a volume of
528 a storage or distribution medium does not bring the other work under
529 the scope of this License.
531 3. You may copy and distribute the Program (or a work based on it,
532 under Section 2) in object code or executable form under the terms of
533 Sections 1 and 2 above provided that you also do one of the following:
535 a) Accompany it with the complete corresponding machine-readable
536 source code, which must be distributed under the terms of Sections
537 1 and 2 above on a medium customarily used for software interchange; or,
539 b) Accompany it with a written offer, valid for at least three
540 years, to give any third party, for a charge no more than your
541 cost of physically performing source distribution, a complete
542 machine-readable copy of the corresponding source code, to be
543 distributed under the terms of Sections 1 and 2 above on a medium
544 customarily used for software interchange; or,
546 c) Accompany it with the information you received as to the offer
547 to distribute corresponding source code. (This alternative is
548 allowed only for noncommercial distribution and only if you
549 received the program in object code or executable form with such
550 an offer, in accord with Subsection b above.)
552 The source code for a work means the preferred form of the work for
553 making modifications to it. For an executable work, complete source
554 code means all the source code for all modules it contains, plus any
555 associated interface definition files, plus the scripts used to
556 control compilation and installation of the executable. However, as a
557 special exception, the source code distributed need not include
558 anything that is normally distributed (in either source or binary
559 form) with the major components (compiler, kernel, and so on) of the
560 operating system on which the executable runs, unless that component
561 itself accompanies the executable.
563 If distribution of executable or object code is made by offering
564 access to copy from a designated place, then offering equivalent
565 access to copy the source code from the same place counts as
566 distribution of the source code, even though third parties are not
567 compelled to copy the source along with the object code.
569 4. You may not copy, modify, sublicense, or distribute the Program
570 except as expressly provided under this License. Any attempt
571 otherwise to copy, modify, sublicense or distribute the Program is
572 void, and will automatically terminate your rights under this License.
573 However, parties who have received copies, or rights, from you under
574 this License will not have their licenses terminated so long as such
575 parties remain in full compliance.
577 5. You are not required to accept this License, since you have not
578 signed it. However, nothing else grants you permission to modify or
579 distribute the Program or its derivative works. These actions are
580 prohibited by law if you do not accept this License. Therefore, by
581 modifying or distributing the Program (or any work based on the
582 Program), you indicate your acceptance of this License to do so, and
583 all its terms and conditions for copying, distributing or modifying
584 the Program or works based on it.
586 6. Each time you redistribute the Program (or any work based on the
587 Program), the recipient automatically receives a license from the
588 original licensor to copy, distribute or modify the Program subject to
589 these terms and conditions. You may not impose any further
590 restrictions on the recipients' exercise of the rights granted herein.
591 You are not responsible for enforcing compliance by third parties to
594 7. If, as a consequence of a court judgment or allegation of patent
595 infringement or for any other reason (not limited to patent issues),
596 conditions are imposed on you (whether by court order, agreement or
597 otherwise) that contradict the conditions of this License, they do not
598 excuse you from the conditions of this License. If you cannot
599 distribute so as to satisfy simultaneously your obligations under this
600 License and any other pertinent obligations, then as a consequence you
601 may not distribute the Program at all. For example, if a patent
602 license would not permit royalty-free redistribution of the Program by
603 all those who receive copies directly or indirectly through you, then
604 the only way you could satisfy both it and this License would be to
605 refrain entirely from distribution of the Program.
607 If any portion of this section is held invalid or unenforceable under
608 any particular circumstance, the balance of the section is intended to
609 apply and the section as a whole is intended to apply in other
612 It is not the purpose of this section to induce you to infringe any
613 patents or other property right claims or to contest validity of any
614 such claims; this section has the sole purpose of protecting the
615 integrity of the free software distribution system, which is
616 implemented by public license practices. Many people have made
617 generous contributions to the wide range of software distributed
618 through that system in reliance on consistent application of that
619 system; it is up to the author/donor to decide if he or she is willing
620 to distribute software through any other system and a licensee cannot
623 This section is intended to make thoroughly clear what is believed to
624 be a consequence of the rest of this License.
626 8. If the distribution and/or use of the Program is restricted in
627 certain countries either by patents or by copyrighted interfaces, the
628 original copyright holder who places the Program under this License
629 may add an explicit geographical distribution limitation excluding
630 those countries, so that distribution is permitted only in or among
631 countries not thus excluded. In such case, this License incorporates
632 the limitation as if written in the body of this License.
634 9. The Free Software Foundation may publish revised and/or new versions
635 of the General Public License from time to time. Such new versions will
636 be similar in spirit to the present version, but may differ in detail to
637 address new problems or concerns.
639 Each version is given a distinguishing version number. If the Program
640 specifies a version number of this License which applies to it and "any
641 later version", you have the option of following the terms and conditions
642 either of that version or of any later version published by the Free
643 Software Foundation. If the Program does not specify a version number of
644 this License, you may choose any version ever published by the Free Software
647 10. If you wish to incorporate parts of the Program into other free
648 programs whose distribution conditions are different, write to the author
649 to ask for permission. For software which is copyrighted by the Free
650 Software Foundation, write to the Free Software Foundation; we sometimes
651 make exceptions for this. Our decision will be guided by the two goals
652 of preserving the free status of all derivatives of our free software and
653 of promoting the sharing and reuse of software generally.
657 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
658 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
659 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
660 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
661 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
662 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
663 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
664 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
665 REPAIR OR CORRECTION.
667 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
668 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
669 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
670 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
671 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
672 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
673 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
674 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
675 POSSIBILITY OF SUCH DAMAGES.
677 END OF TERMS AND CONDITIONS
679 How to Apply These Terms to Your New Programs
681 If you develop a new program, and you want it to be of the greatest
682 possible use to the public, the best way to achieve this is to make it
683 free software which everyone can redistribute and change under these terms.
685 To do so, attach the following notices to the program. It is safest
686 to attach them to the start of each source file to most effectively
687 convey the exclusion of warranty; and each file should have at least
688 the "copyright" line and a pointer to where the full notice is found.
690 <one line to give the program's name and a brief idea of what it does.>
691 Copyright (C) <year> <name of author>
693 This program is free software; you can redistribute it and/or modify
694 it under the terms of the GNU General Public License as published by
695 the Free Software Foundation; either version 2 of the License, or
696 (at your option) any later version.
698 This program is distributed in the hope that it will be useful,
699 but WITHOUT ANY WARRANTY; without even the implied warranty of
700 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
701 GNU General Public License for more details.
703 You should have received a copy of the GNU General Public License along
704 with this program; if not, write to the Free Software Foundation, Inc.,
705 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
707 Also add information on how to contact you by electronic and paper mail.
709 If the program is interactive, make it output a short notice like this
710 when it starts in an interactive mode:
712 Gnomovision version 69, Copyright (C) year name of author
713 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
714 This is free software, and you are welcome to redistribute it
715 under certain conditions; type `show c' for details.
717 The hypothetical commands `show w' and `show c' should show the appropriate
718 parts of the General Public License. Of course, the commands you use may
719 be called something other than `show w' and `show c'; they could even be
720 mouse-clicks or menu items--whatever suits your program.
722 You should also get your employer (if you work as a programmer) or your
723 school, if any, to sign a "copyright disclaimer" for the program, if
724 necessary. Here is a sample; alter the names:
726 Yoyodyne, Inc., hereby disclaims all copyright interest in the program

732 This General Public License does not permit incorporating your program into
733 proprietary programs. If your program is a subroutine library, you may
734 consider it more useful to permit linking proprietary applications with the
735 library. If this is what you want to do, use the GNU Lesser General
736 Public License instead of this License.
737 GNU LESSER GENERAL PUBLIC LICENSE
738 Version 2.1, February 1999
740 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
741 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
742 Everyone is permitted to copy and distribute verbatim copies
743 of this license document, but changing it is not allowed.
745 [This is the first released version of the Lesser GPL. It also counts
746 as the successor of the GNU Library Public License, version 2, hence
747 the version number 2.1.]
751 The licenses for most software are designed to take away your
752 freedom to share and change it. By contrast, the GNU General Public
753 Licenses are intended to guarantee your freedom to share and change
754 free software--to make sure the software is free for all its users.
756 This license, the Lesser General Public License, applies to some
757 specially designated software packages--typically libraries--of the
758 Free Software Foundation and other authors who decide to use it. You
759 can use it too, but we suggest you first think carefully about whether
760 this license or the ordinary General Public License is the better
761 strategy to use in any particular case, based on the explanations below.
763 When we speak of free software, we are referring to freedom of use,
764 not price. Our General Public Licenses are designed to make sure that
765 you have the freedom to distribute copies of free software (and charge
766 for this service if you wish); that you receive source code or can get
767 it if you want it; that you can change the software and use pieces of
768 it in new free programs; and that you are informed that you can do
771 To protect your rights, we need to make restrictions that forbid
772 distributors to deny you these rights or to ask you to surrender these
773 rights. These restrictions translate to certain responsibilities for
774 you if you distribute copies of the library or if you modify it.
776 For example, if you distribute copies of the library, whether gratis
777 or for a fee, you must give the recipients all the rights that we gave
778 you. You must make sure that they, too, receive or can get the source
779 code. If you link other code with the library, you must provide
780 complete object files to the recipients, so that they can relink them
781 with the library after making changes to the library and recompiling
782 it. And you must show them these terms so they know their rights.
784 We protect your rights with a two-step method: (1) we copyright the
785 library, and (2) we offer you this license, which gives you legal
786 permission to copy, distribute and/or modify the library.
788 To protect each distributor, we want to make it very clear that
789 there is no warranty for the free library. Also, if the library is
790 modified by someone else and passed on, the recipients should know
791 that what they have is not the original version, so that the original
792 author's reputation will not be affected by problems that might be
793 introduced by others.
795 Finally, software patents pose a constant threat to the existence of
796 any free program. We wish to make sure that a company cannot
797 effectively restrict the users of a free program by obtaining a
798 restrictive license from a patent holder. Therefore, we insist that
799 any patent license obtained for a version of the library must be
800 consistent with the full freedom of use specified in this license.
802 Most GNU software, including some libraries, is covered by the
803 ordinary GNU General Public License. This license, the GNU Lesser
804 General Public License, applies to certain designated libraries, and
805 is quite different from the ordinary General Public License. We use
806 this license for certain libraries in order to permit linking those
807 libraries into non-free programs.
809 When a program is linked with a library, whether statically or using
810 a shared library, the combination of the two is legally speaking a
811 combined work, a derivative of the original library. The ordinary
812 General Public License therefore permits such linking only if the
813 entire combination fits its criteria of freedom. The Lesser General
814 Public License permits more lax criteria for linking other code with
817 We call this license the "Lesser" General Public License because it
818 does Less to protect the user's freedom than the ordinary General
819 Public License. It also provides other free software developers Less
820 of an advantage over competing non-free programs. These disadvantages
821 are the reason we use the ordinary General Public License for many
822 libraries. However, the Lesser license provides advantages in certain
823 special circumstances.
825 For example, on rare occasions, there may be a special need to
826 encourage the widest possible use of a certain library, so that it becomes
827 a de-facto standard. To achieve this, non-free programs must be
828 allowed to use the library. A more frequent case is that a free
829 library does the same job as widely used non-free libraries. In this
830 case, there is little to gain by limiting the free library to free
831 software only, so we use the Lesser General Public License.
833 In other cases, permission to use a particular library in non-free
834 programs enables a greater number of people to use a large body of
835 free software. For example, permission to use the GNU C Library in
836 non-free programs enables many more people to use the whole GNU
837 operating system, as well as its variant, the GNU/Linux operating
840 Although the Lesser General Public License is Less protective of the
841 users' freedom, it does ensure that the user of a program that is
842 linked with the Library has the freedom and the wherewithal to run
843 that program using a modified version of the Library.
845 The precise terms and conditions for copying, distribution and
846 modification follow. Pay close attention to the difference between a
847 "work based on the library" and a "work that uses the library". The
848 former contains code derived from the library, whereas the latter must
849 be combined with the library in order to run.
851 GNU LESSER GENERAL PUBLIC LICENSE
852 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
854 0. This License Agreement applies to any software library or other
855 program which contains a notice placed by the copyright holder or
856 other authorized party saying it may be distributed under the terms of
857 this Lesser General Public License (also called "this License").
858 Each licensee is addressed as "you".
860 A "library" means a collection of software functions and/or data
861 prepared so as to be conveniently linked with application programs
862 (which use some of those functions and data) to form executables.
864 The "Library", below, refers to any such software library or work
865 which has been distributed under these terms. A "work based on the
866 Library" means either the Library or any derivative work under
867 copyright law: that is to say, a work containing the Library or a
868 portion of it, either verbatim or with modifications and/or translated
869 straightforwardly into another language. (Hereinafter, translation is
870 included without limitation in the term "modification".)
872 "Source code" for a work means the preferred form of the work for
873 making modifications to it. For a library, complete source code means
874 all the source code for all modules it contains, plus any associated
875 interface definition files, plus the scripts used to control compilation
876 and installation of the library.
878 Activities other than copying, distribution and modification are not
879 covered by this License; they are outside its scope. The act of
880 running a program using the Library is not restricted, and output from
881 such a program is covered only if its contents constitute a work based
882 on the Library (independent of the use of the Library in a tool for
883 writing it). Whether that is true depends on what the Library does
884 and what the program that uses the Library does.
886 1. You may copy and distribute verbatim copies of the Library's
887 complete source code as you receive it, in any medium, provided that
888 you conspicuously and appropriately publish on each copy an
889 appropriate copyright notice and disclaimer of warranty; keep intact
890 all the notices that refer to this License and to the absence of any
891 warranty; and distribute a copy of this License along with the
894 You may charge a fee for the physical act of transferring a copy,
895 and you may at your option offer warranty protection in exchange for a
898 2. You may modify your copy or copies of the Library or any portion
899 of it, thus forming a work based on the Library, and copy and
900 distribute such modifications or work under the terms of Section 1
901 above, provided that you also meet all of these conditions:
903 a) The modified work must itself be a software library.
905 b) You must cause the files modified to carry prominent notices
906 stating that you changed the files and the date of any change.
908 c) You must cause the whole of the work to be licensed at no
909 charge to all third parties under the terms of this License.
911 d) If a facility in the modified Library refers to a function or a
912 table of data to be supplied by an application program that uses
913 the facility, other than as an argument passed when the facility
914 is invoked, then you must make a good faith effort to ensure that,
915 in the event an application does not supply such function or
916 table, the facility still operates, and performs whatever part of
917 its purpose remains meaningful.
919 (For example, a function in a library to compute square roots has
920 a purpose that is entirely well-defined independent of the
921 application. Therefore, Subsection 2d requires that any
922 application-supplied function or table used by this function must
923 be optional: if the application does not supply it, the square
924 root function must still compute square roots.)
926 These requirements apply to the modified work as a whole. If
927 identifiable sections of that work are not derived from the Library,
928 and can be reasonably considered independent and separate works in
929 themselves, then this License, and its terms, do not apply to those
930 sections when you distribute them as separate works. But when you
931 distribute the same sections as part of a whole which is a work based
932 on the Library, the distribution of the whole must be on the terms of
933 this License, whose permissions for other licensees extend to the
934 entire whole, and thus to each and every part regardless of who wrote
937 Thus, it is not the intent of this section to claim rights or contest
938 your rights to work written entirely by you; rather, the intent is to
939 exercise the right to control the distribution of derivative or
940 collective works based on the Library.
942 In addition, mere aggregation of another work not based on the Library
943 with the Library (or with a work based on the Library) on a volume of
944 a storage or distribution medium does not bring the other work under
945 the scope of this License.
947 3. You may opt to apply the terms of the ordinary GNU General Public
948 License instead of this License to a given copy of the Library. To do
949 this, you must alter all the notices that refer to this License, so
950 that they refer to the ordinary GNU General Public License, version 2,
951 instead of to this License. (If a newer version than version 2 of the
952 ordinary GNU General Public License has appeared, then you can specify
953 that version instead if you wish.) Do not make any other change in
956 Once this change is made in a given copy, it is irreversible for
957 that copy, so the ordinary GNU General Public License applies to all
958 subsequent copies and derivative works made from that copy.
960 This option is useful when you wish to copy part of the code of
961 the Library into a program that is not a library.
963 4. You may copy and distribute the Library (or a portion or
964 derivative of it, under Section 2) in object code or executable form
965 under the terms of Sections 1 and 2 above provided that you accompany
966 it with the complete corresponding machine-readable source code, which
967 must be distributed under the terms of Sections 1 and 2 above on a
968 medium customarily used for software interchange.
970 If distribution of object code is made by offering access to copy
971 from a designated place, then offering equivalent access to copy the
972 source code from the same place satisfies the requirement to
973 distribute the source code, even though third parties are not
974 compelled to copy the source along with the object code.
976 5. A program that contains no derivative of any portion of the
977 Library, but is designed to work with the Library by being compiled or
978 linked with it, is called a "work that uses the Library". Such a
979 work, in isolation, is not a derivative work of the Library, and
980 therefore falls outside the scope of this License.
982 However, linking a "work that uses the Library" with the Library
983 creates an executable that is a derivative of the Library (because it
984 contains portions of the Library), rather than a "work that uses the
985 library". The executable is therefore covered by this License.
986 Section 6 states terms for distribution of such executables.
988 When a "work that uses the Library" uses material from a header file
989 that is part of the Library, the object code for the work may be a
990 derivative work of the Library even though the source code is not.
991 Whether this is true is especially significant if the work can be
992 linked without the Library, or if the work is itself a library. The
993 threshold for this to be true is not precisely defined by law.
995 If such an object file uses only numerical parameters, data
996 structure layouts and accessors, and small macros and small inline
997 functions (ten lines or less in length), then the use of the object
998 file is unrestricted, regardless of whether it is legally a derivative
999 work. (Executables containing this object code plus portions of the
1000 Library will still fall under Section 6.)
1002 Otherwise, if the work is a derivative of the Library, you may
1003 distribute the object code for the work under the terms of Section 6.
1004 Any executables containing that work also fall under Section 6,
1005 whether or not they are linked directly with the Library itself.
1007 6. As an exception to the Sections above, you may also combine or
1008 link a "work that uses the Library" with the Library to produce a
1009 work containing portions of the Library, and distribute that work
1010 under terms of your choice, provided that the terms permit
1011 modification of the work for the customer's own use and reverse
1012 engineering for debugging such modifications.
1014 You must give prominent notice with each copy of the work that the
1015 Library is used in it and that the Library and its use are covered by
1016 this License. You must supply a copy of this License. If the work
1017 during execution displays copyright notices, you must include the
1018 copyright notice for the Library among them, as well as a reference
1019 directing the user to the copy of this License. Also, you must do one
1022 a) Accompany the work with the complete corresponding
1023 machine-readable source code for the Library including whatever
1024 changes were used in the work (which must be distributed under
1025 Sections 1 and 2 above); and, if the work is an executable linked
1026 with the Library, with the complete machine-readable "work that
1027 uses the Library", as object code and/or source code, so that the
1028 user can modify the Library and then relink to produce a modified
1029 executable containing the modified Library. (It is understood
1030 that the user who changes the contents of definitions files in the
1031 Library will not necessarily be able to recompile the application
1032 to use the modified definitions.)
1034 b) Use a suitable shared library mechanism for linking with the
1035 Library. A suitable mechanism is one that (1) uses at run time a
1036 copy of the library already present on the user's computer system,
1037 rather than copying library functions into the executable, and (2)
1038 will operate properly with a modified version of the library, if
1039 the user installs one, as long as the modified version is
1040 interface-compatible with the version that the work was made with.
1042 c) Accompany the work with a written offer, valid for at
1043 least three years, to give the same user the materials
1044 specified in Subsection 6a, above, for a charge no more
1045 than the cost of performing this distribution.
1047 d) If distribution of the work is made by offering access to copy
1048 from a designated place, offer equivalent access to copy the above
1049 specified materials from the same place.
1051 e) Verify that the user has already received a copy of these
1052 materials or that you have already sent this user a copy.
1054 For an executable, the required form of the "work that uses the
1055 Library" must include any data and utility programs needed for
1056 reproducing the executable from it. However, as a special exception,
1057 the materials to be distributed need not include anything that is
1058 normally distributed (in either source or binary form) with the major
1059 components (compiler, kernel, and so on) of the operating system on
1060 which the executable runs, unless that component itself accompanies
1063 It may happen that this requirement contradicts the license
1064 restrictions of other proprietary libraries that do not normally
1065 accompany the operating system. Such a contradiction means you cannot
1066 use both them and the Library together in an executable that you
1069 7. You may place library facilities that are a work based on the
1070 Library side-by-side in a single library together with other library
1071 facilities not covered by this License, and distribute such a combined
1072 library, provided that the separate distribution of the work based on
1073 the Library and of the other library facilities is otherwise
1074 permitted, and provided that you do these two things:
1076 a) Accompany the combined library with a copy of the same work
1077 based on the Library, uncombined with any other library
1078 facilities. This must be distributed under the terms of the
1081 b) Give prominent notice with the combined library of the fact
1082 that part of it is a work based on the Library, and explaining
1083 where to find the accompanying uncombined form of the same work.
1085 8. You may not copy, modify, sublicense, link with, or distribute
1086 the Library except as expressly provided under this License. Any
1087 attempt otherwise to copy, modify, sublicense, link with, or
1088 distribute the Library is void, and will automatically terminate your
1089 rights under this License. However, parties who have received copies,
1090 or rights, from you under this License will not have their licenses
1091 terminated so long as such parties remain in full compliance.
1093 9. You are not required to accept this License, since you have not
1094 signed it. However, nothing else grants you permission to modify or
1095 distribute the Library or its derivative works. These actions are
1096 prohibited by law if you do not accept this License. Therefore, by
1097 modifying or distributing the Library (or any work based on the
1098 Library), you indicate your acceptance of this License to do so, and
1099 all its terms and conditions for copying, distributing or modifying
1100 the Library or works based on it.
1102 10. Each time you redistribute the Library (or any work based on the
1103 Library), the recipient automatically receives a license from the
1104 original licensor to copy, distribute, link with or modify the Library
1105 subject to these terms and conditions. You may not impose any further
1106 restrictions on the recipients' exercise of the rights granted herein.
1107 You are not responsible for enforcing compliance by third parties with
1110 11. If, as a consequence of a court judgment or allegation of patent
1111 infringement or for any other reason (not limited to patent issues),
1112 conditions are imposed on you (whether by court order, agreement or
1113 otherwise) that contradict the conditions of this License, they do not
1114 excuse you from the conditions of this License. If you cannot
1115 distribute so as to satisfy simultaneously your obligations under this
1116 License and any other pertinent obligations, then as a consequence you
1117 may not distribute the Library at all. For example, if a patent
1118 license would not permit royalty-free redistribution of the Library by
1119 all those who receive copies directly or indirectly through you, then
1120 the only way you could satisfy both it and this License would be to
1121 refrain entirely from distribution of the Library.
1123 If any portion of this section is held invalid or unenforceable under any
1124 particular circumstance, the balance of the section is intended to apply,
1125 and the section as a whole is intended to apply in other circumstances.
1127 It is not the purpose of this section to induce you to infringe any
1128 patents or other property right claims or to contest validity of any
1129 such claims; this section has the sole purpose of protecting the
1130 integrity of the free software distribution system which is
1131 implemented by public license practices. Many people have made
1132 generous contributions to the wide range of software distributed
1133 through that system in reliance on consistent application of that
1134 system; it is up to the author/donor to decide if he or she is willing
1135 to distribute software through any other system and a licensee cannot
1138 This section is intended to make thoroughly clear what is believed to
1139 be a consequence of the rest of this License.
1141 12. If the distribution and/or use of the Library is restricted in
1142 certain countries either by patents or by copyrighted interfaces, the
1143 original copyright holder who places the Library under this License may add
1144 an explicit geographical distribution limitation excluding those countries,
1145 so that distribution is permitted only in or among countries not thus
1146 excluded. In such case, this License incorporates the limitation as if
1147 written in the body of this License.
1149 13. The Free Software Foundation may publish revised and/or new
1150 versions of the Lesser General Public License from time to time.
1151 Such new versions will be similar in spirit to the present version,
1152 but may differ in detail to address new problems or concerns.
1154 Each version is given a distinguishing version number. If the Library
1155 specifies a version number of this License which applies to it and
1156 "any later version", you have the option of following the terms and
1157 conditions either of that version or of any later version published by
1158 the Free Software Foundation. If the Library does not specify a
1159 license version number, you may choose any version ever published by
1160 the Free Software Foundation.
1162 14. If you wish to incorporate parts of the Library into other free
1163 programs whose distribution conditions are incompatible with these,
1164 write to the author to ask for permission. For software which is
1165 copyrighted by the Free Software Foundation, write to the Free
1166 Software Foundation; we sometimes make exceptions for this. Our
1167 decision will be guided by the two goals of preserving the free status
1168 of all derivatives of our free software and of promoting the sharing
1169 and reuse of software generally.
1173 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
1174 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
1175 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
1176 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
1177 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
1178 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
1179 PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
1180 LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
1181 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
1183 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
1184 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
1185 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
1186 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
1187 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
1188 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
1189 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
1190 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
1191 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
1194 END OF TERMS AND CONDITIONS
1196 How to Apply These Terms to Your New Libraries
1198 If you develop a new library, and you want it to be of the greatest
1199 possible use to the public, we recommend making it free software that
1200 everyone can redistribute and change. You can do so by permitting
1201 redistribution under these terms (or, alternatively, under the terms of the
1202 ordinary General Public License).
1204 To apply these terms, attach the following notices to the library. It is
1205 safest to attach them to the start of each source file to most effectively
1206 convey the exclusion of warranty; and each file should have at least the
1207 "copyright" line and a pointer to where the full notice is found.
1209 <one line to give the library's name and a brief idea of what it does.>
1210 Copyright (C) <year> <name of author>

1217 This library is distributed in the hope that it will be useful,
1218 but WITHOUT ANY WARRANTY; without even the implied warranty of

1223 License along with this library; if not, write to the Free Software
1224 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
1226 Also add information on how to contact you by electronic and paper mail.
1228 You should also get your employer (if you work as a programmer) or your
1229 school, if any, to sign a "copyright disclaimer" for the library, if
1230 necessary. Here is a sample; alter the names:
