19Everyone is permitted to copy and distribute verbatim copies
20of this license document, but changing it is not allowed.
21
22                            Preamble
23
24  The licenses for most software are designed to take away your
25freedom to share and change it.  By contrast, the GNU General Public
26License is intended to guarantee your freedom to share and change free
27software--to make sure the software is free for all its users.  This
28General Public License applies to most of the Free Software
29Foundation's software and to any other program whose authors commit to
30using it.  (Some other Free Software Foundation software is covered by
31the GNU Library General Public License instead.)  You can apply it to
32your programs, too.
33
34  When we speak of free software, we are referring to freedom, not
35price.  Our General Public Licenses are designed to make sure that you
36have the freedom to distribute copies of free software (and charge for
37this service if you wish), that you receive source code or can get it
38if you want it, that you can change the software or use pieces of it
39in new free programs; and that you know you can do these things.
40
41  To protect your rights, we need to make restrictions that forbid
42anyone to deny you these rights or to ask you to surrender the rights.
43These restrictions translate to certain responsibilities for you if you
44distribute copies of the software, or if you modify it.
45
46  For example, if you distribute copies of such a program, whether
47gratis or for a fee, you must give the recipients all the rights that
48you have.  You must make sure that they, too, receive or can get the
49source code.  And you must show them these terms so they know their
50rights.
51
52  We protect your rights with two steps: (1) copyright the software, and
53(2) offer you this license which gives you legal permission to copy,
54distribute and/or modify the software.
55
56  Also, for each author's protection and ours, we want to make certain
57that everyone understands that there is no warranty for this free
58software.  If the software is modified by someone else and passed on, we
59want its recipients to know that what they have is not the original, so
60that any problems introduced by others will not reflect on the original
61authors' reputations.
62
63  Finally, any free program is threatened constantly by software
64patents.  We wish to avoid the danger that redistributors of a free
65program will individually obtain patent licenses, in effect making the
66program proprietary.  To prevent this, we have made it clear that any
67patent must be licensed for everyone's free use or not licensed at all.
68
69  The precise terms and conditions for copying, distribution and
70modification follow.
71
72                    GNU GENERAL PUBLIC LICENSE
73   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
74
75  0. This License applies to any program or other work which contains
76a notice placed by the copyright holder saying it may be distributed
77under the terms of this General Public License.  The "Program", below,
78refers to any such program or work, and a "work based on the Program"
79means either the Program or any derivative work under copyright law:
80that is to say, a work containing the Program or a portion of it,
81either verbatim or with modifications and/or translated into another
82language.  (Hereinafter, translation is included without limitation in
83the term "modification".)  Each licensee is addressed as "you".
84
85Activities other than copying, distribution and modification are not
86covered by this License; they are outside its scope.  The act of
87running the Program is not restricted, and the output from the Program
88is covered only if its contents constitute a work based on the
89Program (independent of having been made by running the Program).
90Whether that is true depends on what the Program does.
91
92  1. You may copy and distribute verbatim copies of the Program's
93source code as you receive it, in any medium, provided that you
94conspicuously and appropriately publish on each copy an appropriate
95copyright notice and disclaimer of warranty; keep intact all the
96notices that refer to this License and to the absence of any warranty;
97and give any other recipients of the Program a copy of this License
98along with the Program.
99
100You may charge a fee for the physical act of transferring a copy, and
101you may at your option offer warranty protection in exchange for a fee.
102
103  2. You may modify your copy or copies of the Program or any portion
104of it, thus forming a work based on the Program, and copy and
105distribute such modifications or work under the terms of Section 1
106above, provided that you also meet all of these conditions:
107
108    a) You must cause the modified files to carry prominent notices
109    stating that you changed the files and the date of any change.
110
111    b) You must cause any work that you distribute or publish, that in
112    whole or in part contains or is derived from the Program or any
113    part thereof, to be licensed as a whole at no charge to all third
114    parties under the terms of this License.
115
116    c) If the modified program normally reads commands interactively
117    when run, you must cause it, when started running for such
118    interactive use in the most ordinary way, to print or display an
119    announcement including an appropriate copyright notice and a
120    notice that there is no warranty (or else, saying that you provide
121    a warranty) and that users may redistribute the program under
122    these conditions, and telling the user how to view a copy of this
123    License.  (Exception: if the Program itself is interactive but
124    does not normally print such an announcement, your work based on
125    the Program is not required to print an announcement.)
126
127These requirements apply to the modified work as a whole.  If
128identifiable sections of that work are not derived from the Program,
129and can be reasonably considered independent and separate works in
130themselves, then this License, and its terms, do not apply to those
131sections when you distribute them as separate works.  But when you
132distribute the same sections as part of a whole which is a work based
133on the Program, the distribution of the whole must be on the terms of
134this License, whose permissions for other licensees extend to the
135entire whole, and thus to each and every part regardless of who wrote it.
136
137Thus, it is not the intent of this section to claim rights or contest
138your rights to work written entirely by you; rather, the intent is to
139exercise the right to control the distribution of derivative or
140collective works based on the Program.
141
142In addition, mere aggregation of another work not based on the Program
143with the Program (or with a work based on the Program) on a volume of
144a storage or distribution medium does not bring the other work under
145the scope of this License.
146
147  3. You may copy and distribute the Program (or a work based on it,
148under Section 2) in object code or executable form under the terms of
149Sections 1 and 2 above provided that you also do one of the following:
150
151    a) Accompany it with the complete corresponding machine-readable
152    source code, which must be distributed under the terms of Sections
153    1 and 2 above on a medium customarily used for software interchange; or,
154
155    b) Accompany it with a written offer, valid for at least three
156    years, to give any third party, for a charge no more than your
157    cost of physically performing source distribution, a complete
158    machine-readable copy of the corresponding source code, to be
159    distributed under the terms of Sections 1 and 2 above on a medium
160    customarily used for software interchange; or,
161
162    c) Accompany it with the information you received as to the offer
163    to distribute corresponding source code.  (This alternative is
164    allowed only for noncommercial distribution and only if you
165    received the program in object code or executable form with such
166    an offer, in accord with Subsection b above.)
167
168The source code for a work means the preferred form of the work for
169making modifications to it.  For an executable work, complete source
170code means all the source code for all modules it contains, plus any
171associated interface definition files, plus the scripts used to
172control compilation and installation of the executable.  However, as a
173special exception, the source code distributed need not include
174anything that is normally distributed (in either source or binary
175form) with the major components (compiler, kernel, and so on) of the
176operating system on which the executable runs, unless that component
177itself accompanies the executable.
178
179If distribution of executable or object code is made by offering
180access to copy from a designated place, then offering equivalent
181access to copy the source code from the same place counts as
182distribution of the source code, even though third parties are not
183compelled to copy the source along with the object code.
184
185  4. You may not copy, modify, sublicense, or distribute the Program
186except as expressly provided under this License.  Any attempt
187otherwise to copy, modify, sublicense or distribute the Program is
188void, and will automatically terminate your rights under this License.
189However, parties who have received copies, or rights, from you under
190this License will not have their licenses terminated so long as such
191parties remain in full compliance.
192
193  5. You are not required to accept this License, since you have not
194signed it.  However, nothing else grants you permission to modify or
195distribute the Program or its derivative works.  These actions are
196prohibited by law if you do not accept this License.  Therefore, by
197modifying or distributing the Program (or any work based on the
198Program), you indicate your acceptance of this License to do so, and
199all its terms and conditions for copying, distributing or modifying
200the Program or works based on it.
201
202  6. Each time you redistribute the Program (or any work based on the
203Program), the recipient automatically receives a license from the
204original licensor to copy, distribute or modify the Program subject to
205these terms and conditions.  You may not impose any further
206restrictions on the recipients' exercise of the rights granted herein.
207You are not responsible for enforcing compliance by third parties to
208this License.
209
210  7. If, as a consequence of a court judgment or allegation of patent
211infringement or for any other reason (not limited to patent issues),
212conditions are imposed on you (whether by court order, agreement or
213otherwise) that contradict the conditions of this License, they do not
214excuse you from the conditions of this License.  If you cannot
215distribute so as to satisfy simultaneously your obligations under this
216License and any other pertinent obligations, then as a consequence you
217may not distribute the Program at all.  For example, if a patent
218license would not permit royalty-free redistribution of the Program by
219all those who receive copies directly or indirectly through you, then
220the only way you could satisfy both it and this License would be to
221refrain entirely from distribution of the Program.
222
223If any portion of this section is held invalid or unenforceable under
224any particular circumstance, the balance of the section is intended to
225apply and the section as a whole is intended to apply in other
226circumstances.
227
228It is not the purpose of this section to induce you to infringe any
229patents or other property right claims or to contest validity of any
230such claims; this section has the sole purpose of protecting the
231integrity of the free software distribution system, which is
232implemented by public license practices.  Many people have made
233generous contributions to the wide range of software distributed
234through that system in reliance on consistent application of that
235system; it is up to the author/donor to decide if he or she is willing
236to distribute software through any other system and a licensee cannot
237impose that choice.
238
239This section is intended to make thoroughly clear what is believed to
240be a consequence of the rest of this License.
241
242  8. If the distribution and/or use of the Program is restricted in
243certain countries either by patents or by copyrighted interfaces, the
244original copyright holder who places the Program under this License
245may add an explicit geographical distribution limitation excluding
246those countries, so that distribution is permitted only in or among
247countries not thus excluded.  In such case, this License incorporates
248the limitation as if written in the body of this License.
249
250  9. The Free Software Foundation may publish revised and/or new versions
251of the General Public License from time to time.  Such new versions will
252be similar in spirit to the present version, but may differ in detail to
253address new problems or concerns.
254
255Each version is given a distinguishing version number.  If the Program
256specifies a version number of this License which applies to it and "any
257later version", you have the option of following the terms and conditions
258either of that version or of any later version published by the Free
259Software Foundation.  If the Program does not specify a version number of
260this License, you may choose any version ever published by the Free Software
261Foundation.
262
263  10. If you wish to incorporate parts of the Program into other free
264programs whose distribution conditions are different, write to the author
265to ask for permission.  For software which is copyrighted by the Free
266Software Foundation, write to the Free Software Foundation; we sometimes
267make exceptions for this.  Our decision will be guided by the two goals
268of preserving the free status of all derivatives of our free software and
269of promoting the sharing and reuse of software generally.
270
271                            NO WARRANTY
272
273  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
274FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
275OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
276PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
277OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
278MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
279TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
280PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
281REPAIR OR CORRECTION.
282
283  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
284WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
285REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
286INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
287OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
288TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
289YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
290PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
291POSSIBILITY OF SUCH DAMAGES.

299
300 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
301 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
302 Everyone is permitted to copy and distribute verbatim copies
303 of this license document, but changing it is not allowed.
304
305[This is the first released version of the Lesser GPL.  It also counts
306 as the successor of the GNU Library Public License, version 2, hence
307 the version number 2.1.]
308
309			    Preamble
310
311  The licenses for most software are designed to take away your
312freedom to share and change it.  By contrast, the GNU General Public
313Licenses are intended to guarantee your freedom to share and change
314free software--to make sure the software is free for all its users.
315
316  This license, the Lesser General Public License, applies to some
317specially designated software packages--typically libraries--of the
318Free Software Foundation and other authors who decide to use it.  You
319can use it too, but we suggest you first think carefully about whether
320this license or the ordinary General Public License is the better
321strategy to use in any particular case, based on the explanations below.
322
323  When we speak of free software, we are referring to freedom of use,
324not price.  Our General Public Licenses are designed to make sure that
325you have the freedom to distribute copies of free software (and charge
326for this service if you wish); that you receive source code or can get
327it if you want it; that you can change the software and use pieces of
328it in new free programs; and that you are informed that you can do
329these things.
330
331  To protect your rights, we need to make restrictions that forbid
332distributors to deny you these rights or to ask you to surrender these
333rights.  These restrictions translate to certain responsibilities for
334you if you distribute copies of the library or if you modify it.
335
336  For example, if you distribute copies of the library, whether gratis
337or for a fee, you must give the recipients all the rights that we gave
338you.  You must make sure that they, too, receive or can get the source
339code.  If you link other code with the library, you must provide
340complete object files to the recipients, so that they can relink them
341with the library after making changes to the library and recompiling
342it.  And you must show them these terms so they know their rights.
343
344  We protect your rights with a two-step method: (1) we copyright the
345library, and (2) we offer you this license, which gives you legal
346permission to copy, distribute and/or modify the library.
347
348  To protect each distributor, we want to make it very clear that
349there is no warranty for the free library.  Also, if the library is
350modified by someone else and passed on, the recipients should know
351that what they have is not the original version, so that the original
352author's reputation will not be affected by problems that might be
353introduced by others.
354
355  Finally, software patents pose a constant threat to the existence of
356any free program.  We wish to make sure that a company cannot
357effectively restrict the users of a free program by obtaining a
358restrictive license from a patent holder.  Therefore, we insist that
359any patent license obtained for a version of the library must be
360consistent with the full freedom of use specified in this license.
361
362  Most GNU software, including some libraries, is covered by the
363ordinary GNU General Public License.  This license, the GNU Lesser
364General Public License, applies to certain designated libraries, and
365is quite different from the ordinary General Public License.  We use
366this license for certain libraries in order to permit linking those
367libraries into non-free programs.
368
369  When a program is linked with a library, whether statically or using
370a shared library, the combination of the two is legally speaking a
371combined work, a derivative of the original library.  The ordinary
372General Public License therefore permits such linking only if the
373entire combination fits its criteria of freedom.  The Lesser General
374Public License permits more lax criteria for linking other code with
375the library.
376
377  We call this license the "Lesser" General Public License because it
378does Less to protect the user's freedom than the ordinary General
379Public License.  It also provides other free software developers Less
380of an advantage over competing non-free programs.  These disadvantages
381are the reason we use the ordinary General Public License for many
382libraries.  However, the Lesser license provides advantages in certain
383special circumstances.
384
385  For example, on rare occasions, there may be a special need to
386encourage the widest possible use of a certain library, so that it becomes
387a de-facto standard.  To achieve this, non-free programs must be
388allowed to use the library.  A more frequent case is that a free
389library does the same job as widely used non-free libraries.  In this
390case, there is little to gain by limiting the free library to free
391software only, so we use the Lesser General Public License.
392
393  In other cases, permission to use a particular library in non-free
394programs enables a greater number of people to use a large body of
395free software.  For example, permission to use the GNU C Library in
396non-free programs enables many more people to use the whole GNU
397operating system, as well as its variant, the GNU/Linux operating
398system.
399
400  Although the Lesser General Public License is Less protective of the
401users' freedom, it does ensure that the user of a program that is
402linked with the Library has the freedom and the wherewithal to run
403that program using a modified version of the Library.
404
405  The precise terms and conditions for copying, distribution and
406modification follow.  Pay close attention to the difference between a
407"work based on the library" and a "work that uses the library".  The
408former contains code derived from the library, whereas the latter must
409be combined with the library in order to run.
410
411		  GNU LESSER GENERAL PUBLIC LICENSE
412   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
413
414  0. This License Agreement applies to any software library or other
415program which contains a notice placed by the copyright holder or
416other authorized party saying it may be distributed under the terms of
417this Lesser General Public License (also called "this License").
418Each licensee is addressed as "you".
419
420  A "library" means a collection of software functions and/or data
421prepared so as to be conveniently linked with application programs
422(which use some of those functions and data) to form executables.
423
424  The "Library", below, refers to any such software library or work
425which has been distributed under these terms.  A "work based on the
426Library" means either the Library or any derivative work under
427copyright law: that is to say, a work containing the Library or a
428portion of it, either verbatim or with modifications and/or translated
429straightforwardly into another language.  (Hereinafter, translation is
430included without limitation in the term "modification".)
431
432  "Source code" for a work means the preferred form of the work for
433making modifications to it.  For a library, complete source code means
434all the source code for all modules it contains, plus any associated
435interface definition files, plus the scripts used to control compilation
436and installation of the library.
437
438  Activities other than copying, distribution and modification are not
439covered by this License; they are outside its scope.  The act of
440running a program using the Library is not restricted, and output from
441such a program is covered only if its contents constitute a work based
442on the Library (independent of the use of the Library in a tool for
443writing it).  Whether that is true depends on what the Library does
444and what the program that uses the Library does.
445  
446  1. You may copy and distribute verbatim copies of the Library's
447complete source code as you receive it, in any medium, provided that
448you conspicuously and appropriately publish on each copy an
449appropriate copyright notice and disclaimer of warranty; keep intact
450all the notices that refer to this License and to the absence of any
451warranty; and distribute a copy of this License along with the
452Library.
453
454  You may charge a fee for the physical act of transferring a copy,
455and you may at your option offer warranty protection in exchange for a
456fee.
457
458  2. You may modify your copy or copies of the Library or any portion
459of it, thus forming a work based on the Library, and copy and
460distribute such modifications or work under the terms of Section 1
461above, provided that you also meet all of these conditions:
462
463    a) The modified work must itself be a software library.
464
465    b) You must cause the files modified to carry prominent notices
466    stating that you changed the files and the date of any change.
467
468    c) You must cause the whole of the work to be licensed at no
469    charge to all third parties under the terms of this License.
470
471    d) If a facility in the modified Library refers to a function or a
472    table of data to be supplied by an application program that uses
473    the facility, other than as an argument passed when the facility
474    is invoked, then you must make a good faith effort to ensure that,
475    in the event an application does not supply such function or
476    table, the facility still operates, and performs whatever part of
477    its purpose remains meaningful.
478
479    (For example, a function in a library to compute square roots has
480    a purpose that is entirely well-defined independent of the
481    application.  Therefore, Subsection 2d requires that any
482    application-supplied function or table used by this function must
483    be optional: if the application does not supply it, the square
484    root function must still compute square roots.)
485
486These requirements apply to the modified work as a whole.  If
487identifiable sections of that work are not derived from the Library,
488and can be reasonably considered independent and separate works in
489themselves, then this License, and its terms, do not apply to those
490sections when you distribute them as separate works.  But when you
491distribute the same sections as part of a whole which is a work based
492on the Library, the distribution of the whole must be on the terms of
493this License, whose permissions for other licensees extend to the
494entire whole, and thus to each and every part regardless of who wrote
495it.
496
497Thus, it is not the intent of this section to claim rights or contest
498your rights to work written entirely by you; rather, the intent is to
499exercise the right to control the distribution of derivative or
500collective works based on the Library.
501
502In addition, mere aggregation of another work not based on the Library
503with the Library (or with a work based on the Library) on a volume of
504a storage or distribution medium does not bring the other work under
505the scope of this License.
506
507  3. You may opt to apply the terms of the ordinary GNU General Public
508License instead of this License to a given copy of the Library.  To do
509this, you must alter all the notices that refer to this License, so
510that they refer to the ordinary GNU General Public License, version 2,
511instead of to this License.  (If a newer version than version 2 of the
512ordinary GNU General Public License has appeared, then you can specify
513that version instead if you wish.)  Do not make any other change in
514these notices.
515
516  Once this change is made in a given copy, it is irreversible for
517that copy, so the ordinary GNU General Public License applies to all
518subsequent copies and derivative works made from that copy.
519
520  This option is useful when you wish to copy part of the code of
521the Library into a program that is not a library.
522
523  4. You may copy and distribute the Library (or a portion or
524derivative of it, under Section 2) in object code or executable form
525under the terms of Sections 1 and 2 above provided that you accompany
526it with the complete corresponding machine-readable source code, which
527must be distributed under the terms of Sections 1 and 2 above on a
528medium customarily used for software interchange.
529
530  If distribution of object code is made by offering access to copy
531from a designated place, then offering equivalent access to copy the
532source code from the same place satisfies the requirement to
533distribute the source code, even though third parties are not
534compelled to copy the source along with the object code.
535
536  5. A program that contains no derivative of any portion of the
537Library, but is designed to work with the Library by being compiled or
538linked with it, is called a "work that uses the Library".  Such a
539work, in isolation, is not a derivative work of the Library, and
540therefore falls outside the scope of this License.
541
542  However, linking a "work that uses the Library" with the Library
543creates an executable that is a derivative of the Library (because it
544contains portions of the Library), rather than a "work that uses the
545library".  The executable is therefore covered by this License.
546Section 6 states terms for distribution of such executables.
547
548  When a "work that uses the Library" uses material from a header file
549that is part of the Library, the object code for the work may be a
550derivative work of the Library even though the source code is not.
551Whether this is true is especially significant if the work can be
552linked without the Library, or if the work is itself a library.  The
553threshold for this to be true is not precisely defined by law.
554
555  If such an object file uses only numerical parameters, data
556structure layouts and accessors, and small macros and small inline
557functions (ten lines or less in length), then the use of the object
558file is unrestricted, regardless of whether it is legally a derivative
559work.  (Executables containing this object code plus portions of the
560Library will still fall under Section 6.)
561
562  Otherwise, if the work is a derivative of the Library, you may
563distribute the object code for the work under the terms of Section 6.
564Any executables containing that work also fall under Section 6,
565whether or not they are linked directly with the Library itself.
566
567  6. As an exception to the Sections above, you may also combine or
568link a "work that uses the Library" with the Library to produce a
569work containing portions of the Library, and distribute that work
570under terms of your choice, provided that the terms permit
571modification of the work for the customer's own use and reverse
572engineering for debugging such modifications.
573
574  You must give prominent notice with each copy of the work that the
575Library is used in it and that the Library and its use are covered by
576this License.  You must supply a copy of this License.  If the work
577during execution displays copyright notices, you must include the
578copyright notice for the Library among them, as well as a reference
579directing the user to the copy of this License.  Also, you must do one
580of these things:
581
582    a) Accompany the work with the complete corresponding
583    machine-readable source code for the Library including whatever
584    changes were used in the work (which must be distributed under
585    Sections 1 and 2 above); and, if the work is an executable linked
586    with the Library, with the complete machine-readable "work that
587    uses the Library", as object code and/or source code, so that the
588    user can modify the Library and then relink to produce a modified
589    executable containing the modified Library.  (It is understood
590    that the user who changes the contents of definitions files in the
591    Library will not necessarily be able to recompile the application
592    to use the modified definitions.)
593
594    b) Use a suitable shared library mechanism for linking with the
595    Library.  A suitable mechanism is one that (1) uses at run time a
596    copy of the library already present on the user's computer system,
597    rather than copying library functions into the executable, and (2)
598    will operate properly with a modified version of the library, if
599    the user installs one, as long as the modified version is
600    interface-compatible with the version that the work was made with.
601
602    c) Accompany the work with a written offer, valid for at
603    least three years, to give the same user the materials
604    specified in Subsection 6a, above, for a charge no more
605    than the cost of performing this distribution.
606
607    d) If distribution of the work is made by offering access to copy
608    from a designated place, offer equivalent access to copy the above
609    specified materials from the same place.
610
611    e) Verify that the user has already received a copy of these
612    materials or that you have already sent this user a copy.
613
614  For an executable, the required form of the "work that uses the
615Library" must include any data and utility programs needed for
616reproducing the executable from it.  However, as a special exception,
617the materials to be distributed need not include anything that is
618normally distributed (in either source or binary form) with the major
619components (compiler, kernel, and so on) of the operating system on
620which the executable runs, unless that component itself accompanies
621the executable.
622
623  It may happen that this requirement contradicts the license
624restrictions of other proprietary libraries that do not normally
625accompany the operating system.  Such a contradiction means you cannot
626use both them and the Library together in an executable that you
627distribute.
628
629  7. You may place library facilities that are a work based on the
630Library side-by-side in a single library together with other library
631facilities not covered by this License, and distribute such a combined
632library, provided that the separate distribution of the work based on
633the Library and of the other library facilities is otherwise
634permitted, and provided that you do these two things:
635
636    a) Accompany the combined library with a copy of the same work
637    based on the Library, uncombined with any other library
638    facilities.  This must be distributed under the terms of the
639    Sections above.
640
641    b) Give prominent notice with the combined library of the fact
642    that part of it is a work based on the Library, and explaining
643    where to find the accompanying uncombined form of the same work.
644
645  8. You may not copy, modify, sublicense, link with, or distribute
646the Library except as expressly provided under this License.  Any
647attempt otherwise to copy, modify, sublicense, link with, or
648distribute the Library is void, and will automatically terminate your
649rights under this License.  However, parties who have received copies,
650or rights, from you under this License will not have their licenses
651terminated so long as such parties remain in full compliance.
652
653  9. You are not required to accept this License, since you have not
654signed it.  However, nothing else grants you permission to modify or
655distribute the Library or its derivative works.  These actions are
656prohibited by law if you do not accept this License.  Therefore, by
657modifying or distributing the Library (or any work based on the
658Library), you indicate your acceptance of this License to do so, and
659all its terms and conditions for copying, distributing or modifying
660the Library or works based on it.
661
662  10. Each time you redistribute the Library (or any work based on the
663Library), the recipient automatically receives a license from the
664original licensor to copy, distribute, link with or modify the Library
665subject to these terms and conditions.  You may not impose any further
666restrictions on the recipients' exercise of the rights granted herein.
667You are not responsible for enforcing compliance by third parties with
668this License.
669
670  11. If, as a consequence of a court judgment or allegation of patent
671infringement or for any other reason (not limited to patent issues),
672conditions are imposed on you (whether by court order, agreement or
673otherwise) that contradict the conditions of this License, they do not
674excuse you from the conditions of this License.  If you cannot
675distribute so as to satisfy simultaneously your obligations under this
676License and any other pertinent obligations, then as a consequence you
677may not distribute the Library at all.  For example, if a patent
678license would not permit royalty-free redistribution of the Library by
679all those who receive copies directly or indirectly through you, then
680the only way you could satisfy both it and this License would be to
681refrain entirely from distribution of the Library.
682
683If any portion of this section is held invalid or unenforceable under any
684particular circumstance, the balance of the section is intended to apply,
685and the section as a whole is intended to apply in other circumstances.
686
687It is not the purpose of this section to induce you to infringe any
688patents or other property right claims or to contest validity of any
689such claims; this section has the sole purpose of protecting the
690integrity of the free software distribution system which is
691implemented by public license practices.  Many people have made
692generous contributions to the wide range of software distributed
693through that system in reliance on consistent application of that
694system; it is up to the author/donor to decide if he or she is willing
695to distribute software through any other system and a licensee cannot
696impose that choice.
697
698This section is intended to make thoroughly clear what is believed to
699be a consequence of the rest of this License.
700
701  12. If the distribution and/or use of the Library is restricted in
702certain countries either by patents or by copyrighted interfaces, the
703original copyright holder who places the Library under this License may add
704an explicit geographical distribution limitation excluding those countries,
705so that distribution is permitted only in or among countries not thus
706excluded.  In such case, this License incorporates the limitation as if
707written in the body of this License.
708
709  13. The Free Software Foundation may publish revised and/or new
710versions of the Lesser General Public License from time to time.
711Such new versions will be similar in spirit to the present version,
712but may differ in detail to address new problems or concerns.
713
714Each version is given a distinguishing version number.  If the Library
715specifies a version number of this License which applies to it and
716"any later version", you have the option of following the terms and
717conditions either of that version or of any later version published by
718the Free Software Foundation.  If the Library does not specify a
719license version number, you may choose any version ever published by
720the Free Software Foundation.
721
722  14. If you wish to incorporate parts of the Library into other free
723programs whose distribution conditions are incompatible with these,
724write to the author to ask for permission.  For software which is
725copyrighted by the Free Software Foundation, write to the Free
726Software Foundation; we sometimes make exceptions for this.  Our
727decision will be guided by the two goals of preserving the free status
728of all derivatives of our free software and of promoting the sharing
729and reuse of software generally.
730
731			    NO WARRANTY
732
733  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
734WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
735EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
736OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
737KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
738IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
739PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
740LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
741THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
742
743  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
744WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
745AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
746FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
747CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
748LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
749RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
750FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
751SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
752DAMAGES.
