9                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
10 Everyone is permitted to copy and distribute verbatim copies
11 of this license document, but changing it is not allowed.
12
13                            Preamble
14
15  The licenses for most software are designed to take away your
16freedom to share and change it.  By contrast, the GNU General Public
17License is intended to guarantee your freedom to share and change free
18software--to make sure the software is free for all its users.  This
19General Public License applies to most of the Free Software
20Foundation's software and to any other program whose authors commit to
21using it.  (Some other Free Software Foundation software is covered by
22the GNU Library General Public License instead.)  You can apply it to
23your programs, too.
24
25  When we speak of free software, we are referring to freedom, not
26price.  Our General Public Licenses are designed to make sure that you
27have the freedom to distribute copies of free software (and charge for
28this service if you wish), that you receive source code or can get it
29if you want it, that you can change the software or use pieces of it
30in new free programs; and that you know you can do these things.
31
32  To protect your rights, we need to make restrictions that forbid
33anyone to deny you these rights or to ask you to surrender the rights.
34These restrictions translate to certain responsibilities for you if you
35distribute copies of the software, or if you modify it.
36
37  For example, if you distribute copies of such a program, whether
38gratis or for a fee, you must give the recipients all the rights that
39you have.  You must make sure that they, too, receive or can get the
40source code.  And you must show them these terms so they know their
41rights.
42
43  We protect your rights with two steps: (1) copyright the software, and
44(2) offer you this license which gives you legal permission to copy,
45distribute and/or modify the software.
46
47  Also, for each author's protection and ours, we want to make certain
48that everyone understands that there is no warranty for this free
49software.  If the software is modified by someone else and passed on, we
50want its recipients to know that what they have is not the original, so
51that any problems introduced by others will not reflect on the original
52authors' reputations.
53
54  Finally, any free program is threatened constantly by software
55patents.  We wish to avoid the danger that redistributors of a free
56program will individually obtain patent licenses, in effect making the
57program proprietary.  To prevent this, we have made it clear that any
58patent must be licensed for everyone's free use or not licensed at all.
59
60  The precise terms and conditions for copying, distribution and
61modification follow.
62
63                    GNU GENERAL PUBLIC LICENSE
64   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
65
66  0. This License applies to any program or other work which contains
67a notice placed by the copyright holder saying it may be distributed
68under the terms of this General Public License.  The "Program", below,
69refers to any such program or work, and a "work based on the Program"
70means either the Program or any derivative work under copyright law:
71that is to say, a work containing the Program or a portion of it,
72either verbatim or with modifications and/or translated into another
73language.  (Hereinafter, translation is included without limitation in
74the term "modification".)  Each licensee is addressed as "you".
75
76Activities other than copying, distribution and modification are not
77covered by this License; they are outside its scope.  The act of
78running the Program is not restricted, and the output from the Program
79is covered only if its contents constitute a work based on the
80Program (independent of having been made by running the Program).
81Whether that is true depends on what the Program does.
82
83  1. You may copy and distribute verbatim copies of the Program's
84source code as you receive it, in any medium, provided that you
85conspicuously and appropriately publish on each copy an appropriate
86copyright notice and disclaimer of warranty; keep intact all the
87notices that refer to this License and to the absence of any warranty;
88and give any other recipients of the Program a copy of this License
89along with the Program.
90
91You may charge a fee for the physical act of transferring a copy, and
92you may at your option offer warranty protection in exchange for a fee.
93
94  2. You may modify your copy or copies of the Program or any portion
95of it, thus forming a work based on the Program, and copy and
96distribute such modifications or work under the terms of Section 1
97above, provided that you also meet all of these conditions:
98
99    a) You must cause the modified files to carry prominent notices
100    stating that you changed the files and the date of any change.
101
102    b) You must cause any work that you distribute or publish, that in
103    whole or in part contains or is derived from the Program or any
104    part thereof, to be licensed as a whole at no charge to all third
105    parties under the terms of this License.
106
107    c) If the modified program normally reads commands interactively
108    when run, you must cause it, when started running for such
109    interactive use in the most ordinary way, to print or display an
110    announcement including an appropriate copyright notice and a
111    notice that there is no warranty (or else, saying that you provide
112    a warranty) and that users may redistribute the program under
113    these conditions, and telling the user how to view a copy of this
114    License.  (Exception: if the Program itself is interactive but
115    does not normally print such an announcement, your work based on
116    the Program is not required to print an announcement.)
117
118These requirements apply to the modified work as a whole.  If
119identifiable sections of that work are not derived from the Program,
120and can be reasonably considered independent and separate works in
121themselves, then this License, and its terms, do not apply to those
122sections when you distribute them as separate works.  But when you
123distribute the same sections as part of a whole which is a work based
124on the Program, the distribution of the whole must be on the terms of
125this License, whose permissions for other licensees extend to the
126entire whole, and thus to each and every part regardless of who wrote it.
127
128Thus, it is not the intent of this section to claim rights or contest
129your rights to work written entirely by you; rather, the intent is to
130exercise the right to control the distribution of derivative or
131collective works based on the Program.
132
133In addition, mere aggregation of another work not based on the Program
134with the Program (or with a work based on the Program) on a volume of
135a storage or distribution medium does not bring the other work under
136the scope of this License.
137
138  3. You may copy and distribute the Program (or a work based on it,
139under Section 2) in object code or executable form under the terms of
140Sections 1 and 2 above provided that you also do one of the following:
141
142    a) Accompany it with the complete corresponding machine-readable
143    source code, which must be distributed under the terms of Sections
144    1 and 2 above on a medium customarily used for software interchange; or,
145
146    b) Accompany it with a written offer, valid for at least three
147    years, to give any third party, for a charge no more than your
148    cost of physically performing source distribution, a complete
149    machine-readable copy of the corresponding source code, to be
150    distributed under the terms of Sections 1 and 2 above on a medium
151    customarily used for software interchange; or,
152
153    c) Accompany it with the information you received as to the offer
154    to distribute corresponding source code.  (This alternative is
155    allowed only for noncommercial distribution and only if you
156    received the program in object code or executable form with such
157    an offer, in accord with Subsection b above.)
158
159The source code for a work means the preferred form of the work for
160making modifications to it.  For an executable work, complete source
161code means all the source code for all modules it contains, plus any
162associated interface definition files, plus the scripts used to
163control compilation and installation of the executable.  However, as a
164special exception, the source code distributed need not include
165anything that is normally distributed (in either source or binary
166form) with the major components (compiler, kernel, and so on) of the
167operating system on which the executable runs, unless that component
168itself accompanies the executable.
169
170If distribution of executable or object code is made by offering
171access to copy from a designated place, then offering equivalent
172access to copy the source code from the same place counts as
173distribution of the source code, even though third parties are not
174compelled to copy the source along with the object code.
175
176  4. You may not copy, modify, sublicense, or distribute the Program
177except as expressly provided under this License.  Any attempt
178otherwise to copy, modify, sublicense or distribute the Program is
179void, and will automatically terminate your rights under this License.
180However, parties who have received copies, or rights, from you under
181this License will not have their licenses terminated so long as such
182parties remain in full compliance.
183
184  5. You are not required to accept this License, since you have not
185signed it.  However, nothing else grants you permission to modify or
186distribute the Program or its derivative works.  These actions are
187prohibited by law if you do not accept this License.  Therefore, by
188modifying or distributing the Program (or any work based on the
189Program), you indicate your acceptance of this License to do so, and
190all its terms and conditions for copying, distributing or modifying
191the Program or works based on it.
192
193  6. Each time you redistribute the Program (or any work based on the
194Program), the recipient automatically receives a license from the
195original licensor to copy, distribute or modify the Program subject to
196these terms and conditions.  You may not impose any further
197restrictions on the recipients' exercise of the rights granted herein.
198You are not responsible for enforcing compliance by third parties to
199this License.
200
201  7. If, as a consequence of a court judgment or allegation of patent
202infringement or for any other reason (not limited to patent issues),
203conditions are imposed on you (whether by court order, agreement or
204otherwise) that contradict the conditions of this License, they do not
205excuse you from the conditions of this License.  If you cannot
206distribute so as to satisfy simultaneously your obligations under this
207License and any other pertinent obligations, then as a consequence you
208may not distribute the Program at all.  For example, if a patent
209license would not permit royalty-free redistribution of the Program by
210all those who receive copies directly or indirectly through you, then
211the only way you could satisfy both it and this License would be to
212refrain entirely from distribution of the Program.
213
214If any portion of this section is held invalid or unenforceable under
215any particular circumstance, the balance of the section is intended to
216apply and the section as a whole is intended to apply in other
217circumstances.
218
219It is not the purpose of this section to induce you to infringe any
220patents or other property right claims or to contest validity of any
221such claims; this section has the sole purpose of protecting the
222integrity of the free software distribution system, which is
223implemented by public license practices.  Many people have made
224generous contributions to the wide range of software distributed
225through that system in reliance on consistent application of that
226system; it is up to the author/donor to decide if he or she is willing
227to distribute software through any other system and a licensee cannot
228impose that choice.
229
230This section is intended to make thoroughly clear what is believed to
231be a consequence of the rest of this License.
232
233  8. If the distribution and/or use of the Program is restricted in
234certain countries either by patents or by copyrighted interfaces, the
235original copyright holder who places the Program under this License
236may add an explicit geographical distribution limitation excluding
237those countries, so that distribution is permitted only in or among
238countries not thus excluded.  In such case, this License incorporates
239the limitation as if written in the body of this License.
240
241  9. The Free Software Foundation may publish revised and/or new versions
242of the General Public License from time to time.  Such new versions will
243be similar in spirit to the present version, but may differ in detail to
244address new problems or concerns.
245
246Each version is given a distinguishing version number.  If the Program
247specifies a version number of this License which applies to it and "any
248later version", you have the option of following the terms and conditions
249either of that version or of any later version published by the Free
250Software Foundation.  If the Program does not specify a version number of
251this License, you may choose any version ever published by the Free Software
252Foundation.
253
254  10. If you wish to incorporate parts of the Program into other free
255programs whose distribution conditions are different, write to the author
256to ask for permission.  For software which is copyrighted by the Free
257Software Foundation, write to the Free Software Foundation; we sometimes
258make exceptions for this.  Our decision will be guided by the two goals
259of preserving the free status of all derivatives of our free software and
260of promoting the sharing and reuse of software generally.
261
262                            NO WARRANTY
263
264  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
265FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
266OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
267PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
268OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
269MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
270TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
271PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
272REPAIR OR CORRECTION.
273
274  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
275WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
276REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
277INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
278OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
279TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
280YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
281PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
282POSSIBILITY OF SUCH DAMAGES.
283
284                     END OF TERMS AND CONDITIONS
285
286            How to Apply These Terms to Your New Programs
287
288  If you develop a new program, and you want it to be of the greatest
289possible use to the public, the best way to achieve this is to make it
290free software which everyone can redistribute and change under these terms.
291
292  To do so, attach the following notices to the program.  It is safest
293to attach them to the start of each source file to most effectively
294convey the exclusion of warranty; and each file should have at least
295the "copyright" line and a pointer to where the full notice is found.
296
297    <one line to give the program's name and a brief idea of what it does.>
298    Copyright (C) <year>  <name of author>
299
300    This program is free software; you can redistribute it and/or modify
301    it under the terms of the GNU General Public License as published by
302    the Free Software Foundation; either version 2 of the License, or
303    (at your option) any later version.
304
305    This program is distributed in the hope that it will be useful,
306    but WITHOUT ANY WARRANTY; without even the implied warranty of
307    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
308    GNU General Public License for more details.
309
310    You should have received a copy of the GNU General Public License
311    along with this program; if not, write to the Free Software
312    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
313
314
315Also add information on how to contact you by electronic and paper mail.
316
317If the program is interactive, make it output a short notice like this
318when it starts in an interactive mode:
319
320    Gnomovision version 69, Copyright (C) year name of author
321    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
322    This is free software, and you are welcome to redistribute it
323    under certain conditions; type `show c' for details.
324
325The hypothetical commands `show w' and `show c' should show the appropriate
326parts of the General Public License.  Of course, the commands you use may
327be called something other than `show w' and `show c'; they could even be
328mouse-clicks or menu items--whatever suits your program.
329
330You should also get your employer (if you work as a programmer) or your
331school, if any, to sign a "copyright disclaimer" for the program, if
332necessary.  Here is a sample; alter the names:
333
334  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
335  `Gnomovision' (which makes passes at compilers) written by James Hacker.
336
337  <signature of Ty Coon>, 1 April 1989
338  Ty Coon, President of Vice
339
340This General Public License does not permit incorporating your program into
341proprietary programs.  If your program is a subroutine library, you may
342consider it more useful to permit linking proprietary applications with the
343library.  If this is what you want to do, use the GNU Library General
344Public License instead of this License.

348                  GNU LESSER GENERAL PUBLIC LICENSE
349                       Version 2.1, February 1999
350
351 Copyright (C) 1991, 1999 Free Software Foundation, Inc.
352     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
353 Everyone is permitted to copy and distribute verbatim copies
354 of this license document, but changing it is not allowed.
355
356[This is the first released version of the Lesser GPL.  It also counts
357 as the successor of the GNU Library Public License, version 2, hence
358 the version number 2.1.]
359
360                            Preamble
361
362  The licenses for most software are designed to take away your
363freedom to share and change it.  By contrast, the GNU General Public
364Licenses are intended to guarantee your freedom to share and change
365free software--to make sure the software is free for all its users.
366
367  This license, the Lesser General Public License, applies to some
368specially designated software packages--typically libraries--of the
369Free Software Foundation and other authors who decide to use it.  You
370can use it too, but we suggest you first think carefully about whether
371this license or the ordinary General Public License is the better
372strategy to use in any particular case, based on the explanations below.
373
374  When we speak of free software, we are referring to freedom of use,
375not price.  Our General Public Licenses are designed to make sure that
376you have the freedom to distribute copies of free software (and charge
377for this service if you wish); that you receive source code or can get
378it if you want it; that you can change the software and use pieces of
379it in new free programs; and that you are informed that you can do
380these things.
381
382  To protect your rights, we need to make restrictions that forbid
383distributors to deny you these rights or to ask you to surrender these
384rights.  These restrictions translate to certain responsibilities for
385you if you distribute copies of the library or if you modify it.
386
387  For example, if you distribute copies of the library, whether gratis
388or for a fee, you must give the recipients all the rights that we gave
389you.  You must make sure that they, too, receive or can get the source
390code.  If you link other code with the library, you must provide
391complete object files to the recipients, so that they can relink them
392with the library after making changes to the library and recompiling
393it.  And you must show them these terms so they know their rights.
394
395  We protect your rights with a two-step method: (1) we copyright the
396library, and (2) we offer you this license, which gives you legal
397permission to copy, distribute and/or modify the library.
398
399  To protect each distributor, we want to make it very clear that
400there is no warranty for the free library.  Also, if the library is
401modified by someone else and passed on, the recipients should know
402that what they have is not the original version, so that the original
403author's reputation will not be affected by problems that might be
404introduced by others.
405
406  Finally, software patents pose a constant threat to the existence of
407any free program.  We wish to make sure that a company cannot
408effectively restrict the users of a free program by obtaining a
409restrictive license from a patent holder.  Therefore, we insist that
410any patent license obtained for a version of the library must be
411consistent with the full freedom of use specified in this license.
412
413  Most GNU software, including some libraries, is covered by the
414ordinary GNU General Public License.  This license, the GNU Lesser
415General Public License, applies to certain designated libraries, and
416is quite different from the ordinary General Public License.  We use
417this license for certain libraries in order to permit linking those
418libraries into non-free programs.
419
420  When a program is linked with a library, whether statically or using
421a shared library, the combination of the two is legally speaking a
422combined work, a derivative of the original library.  The ordinary
423General Public License therefore permits such linking only if the
424entire combination fits its criteria of freedom.  The Lesser General
425Public License permits more lax criteria for linking other code with
426the library.
427
428  We call this license the "Lesser" General Public License because it
429does Less to protect the user's freedom than the ordinary General
430Public License.  It also provides other free software developers Less
431of an advantage over competing non-free programs.  These disadvantages
432are the reason we use the ordinary General Public License for many
433libraries.  However, the Lesser license provides advantages in certain
434special circumstances.
435
436  For example, on rare occasions, there may be a special need to
437encourage the widest possible use of a certain library, so that it becomes
438a de-facto standard.  To achieve this, non-free programs must be
439allowed to use the library.  A more frequent case is that a free
440library does the same job as widely used non-free libraries.  In this
441case, there is little to gain by limiting the free library to free
442software only, so we use the Lesser General Public License.
443
444  In other cases, permission to use a particular library in non-free
445programs enables a greater number of people to use a large body of
446free software.  For example, permission to use the GNU C Library in
447non-free programs enables many more people to use the whole GNU
448operating system, as well as its variant, the GNU/Linux operating
449system.
450
451  Although the Lesser General Public License is Less protective of the
452users' freedom, it does ensure that the user of a program that is
453linked with the Library has the freedom and the wherewithal to run
454that program using a modified version of the Library.
455
456  The precise terms and conditions for copying, distribution and
457modification follow.  Pay close attention to the difference between a
458"work based on the library" and a "work that uses the library".  The
459former contains code derived from the library, whereas the latter must
460be combined with the library in order to run.
461
462                  GNU LESSER GENERAL PUBLIC LICENSE
463   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
464
465  0. This License Agreement applies to any software library or other
466program which contains a notice placed by the copyright holder or
467other authorized party saying it may be distributed under the terms of
468this Lesser General Public License (also called "this License").
469Each licensee is addressed as "you".
470
471  A "library" means a collection of software functions and/or data
472prepared so as to be conveniently linked with application programs
473(which use some of those functions and data) to form executables.
474
475  The "Library", below, refers to any such software library or work
476which has been distributed under these terms.  A "work based on the
477Library" means either the Library or any derivative work under
478copyright law: that is to say, a work containing the Library or a
479portion of it, either verbatim or with modifications and/or translated
480straightforwardly into another language.  (Hereinafter, translation is
481included without limitation in the term "modification".)
482
483  "Source code" for a work means the preferred form of the work for
484making modifications to it.  For a library, complete source code means
485all the source code for all modules it contains, plus any associated
486interface definition files, plus the scripts used to control compilation
487and installation of the library.
488
489  Activities other than copying, distribution and modification are not
490covered by this License; they are outside its scope.  The act of
491running a program using the Library is not restricted, and output from
492such a program is covered only if its contents constitute a work based
493on the Library (independent of the use of the Library in a tool for
494writing it).  Whether that is true depends on what the Library does
495and what the program that uses the Library does.
496 
497  1. You may copy and distribute verbatim copies of the Library's
498complete source code as you receive it, in any medium, provided that
499you conspicuously and appropriately publish on each copy an
500appropriate copyright notice and disclaimer of warranty; keep intact
501all the notices that refer to this License and to the absence of any
502warranty; and distribute a copy of this License along with the
503Library.
504
505  You may charge a fee for the physical act of transferring a copy,
506and you may at your option offer warranty protection in exchange for a
507fee.
508
509  2. You may modify your copy or copies of the Library or any portion
510of it, thus forming a work based on the Library, and copy and
511distribute such modifications or work under the terms of Section 1
512above, provided that you also meet all of these conditions:
513
514    a) The modified work must itself be a software library.
515
516    b) You must cause the files modified to carry prominent notices
517    stating that you changed the files and the date of any change.
518
519    c) You must cause the whole of the work to be licensed at no
520    charge to all third parties under the terms of this License.
521
522    d) If a facility in the modified Library refers to a function or a
523    table of data to be supplied by an application program that uses
524    the facility, other than as an argument passed when the facility
525    is invoked, then you must make a good faith effort to ensure that,
526    in the event an application does not supply such function or
527    table, the facility still operates, and performs whatever part of
528    its purpose remains meaningful.
529
530    (For example, a function in a library to compute square roots has
531    a purpose that is entirely well-defined independent of the
532    application.  Therefore, Subsection 2d requires that any
533    application-supplied function or table used by this function must
534    be optional: if the application does not supply it, the square
535    root function must still compute square roots.)
536
537These requirements apply to the modified work as a whole.  If
538identifiable sections of that work are not derived from the Library,
539and can be reasonably considered independent and separate works in
540themselves, then this License, and its terms, do not apply to those
541sections when you distribute them as separate works.  But when you
542distribute the same sections as part of a whole which is a work based
543on the Library, the distribution of the whole must be on the terms of
544this License, whose permissions for other licensees extend to the
545entire whole, and thus to each and every part regardless of who wrote
546it.
547
548Thus, it is not the intent of this section to claim rights or contest
549your rights to work written entirely by you; rather, the intent is to
550exercise the right to control the distribution of derivative or
551collective works based on the Library.
552
553In addition, mere aggregation of another work not based on the Library
554with the Library (or with a work based on the Library) on a volume of
555a storage or distribution medium does not bring the other work under
556the scope of this License.
557
558  3. You may opt to apply the terms of the ordinary GNU General Public
559License instead of this License to a given copy of the Library.  To do
560this, you must alter all the notices that refer to this License, so
561that they refer to the ordinary GNU General Public License, version 2,
562instead of to this License.  (If a newer version than version 2 of the
563ordinary GNU General Public License has appeared, then you can specify
564that version instead if you wish.)  Do not make any other change in
565these notices.
566
567  Once this change is made in a given copy, it is irreversible for
568that copy, so the ordinary GNU General Public License applies to all
569subsequent copies and derivative works made from that copy.
570
571  This option is useful when you wish to copy part of the code of
572the Library into a program that is not a library.
573
574  4. You may copy and distribute the Library (or a portion or
575derivative of it, under Section 2) in object code or executable form
576under the terms of Sections 1 and 2 above provided that you accompany
577it with the complete corresponding machine-readable source code, which
578must be distributed under the terms of Sections 1 and 2 above on a
579medium customarily used for software interchange.
580
581  If distribution of object code is made by offering access to copy
582from a designated place, then offering equivalent access to copy the
583source code from the same place satisfies the requirement to
584distribute the source code, even though third parties are not
585compelled to copy the source along with the object code.
586
587  5. A program that contains no derivative of any portion of the
588Library, but is designed to work with the Library by being compiled or
589linked with it, is called a "work that uses the Library".  Such a
590work, in isolation, is not a derivative work of the Library, and
591therefore falls outside the scope of this License.
592
593  However, linking a "work that uses the Library" with the Library
594creates an executable that is a derivative of the Library (because it
595contains portions of the Library), rather than a "work that uses the
596library".  The executable is therefore covered by this License.
597Section 6 states terms for distribution of such executables.
598
599  When a "work that uses the Library" uses material from a header file
600that is part of the Library, the object code for the work may be a
601derivative work of the Library even though the source code is not.
602Whether this is true is especially significant if the work can be
603linked without the Library, or if the work is itself a library.  The
604threshold for this to be true is not precisely defined by law.
605
606  If such an object file uses only numerical parameters, data
607structure layouts and accessors, and small macros and small inline
608functions (ten lines or less in length), then the use of the object
609file is unrestricted, regardless of whether it is legally a derivative
610work.  (Executables containing this object code plus portions of the
611Library will still fall under Section 6.)
612
613  Otherwise, if the work is a derivative of the Library, you may
614distribute the object code for the work under the terms of Section 6.
615Any executables containing that work also fall under Section 6,
616whether or not they are linked directly with the Library itself.
617
618  6. As an exception to the Sections above, you may also combine or
619link a "work that uses the Library" with the Library to produce a
620work containing portions of the Library, and distribute that work
621under terms of your choice, provided that the terms permit
622modification of the work for the customer's own use and reverse
623engineering for debugging such modifications.
624
625  You must give prominent notice with each copy of the work that the
626Library is used in it and that the Library and its use are covered by
627this License.  You must supply a copy of this License.  If the work
628during execution displays copyright notices, you must include the
629copyright notice for the Library among them, as well as a reference
630directing the user to the copy of this License.  Also, you must do one
631of these things:
632
633    a) Accompany the work with the complete corresponding
634    machine-readable source code for the Library including whatever
635    changes were used in the work (which must be distributed under
636    Sections 1 and 2 above); and, if the work is an executable linked
637    with the Library, with the complete machine-readable "work that
638    uses the Library", as object code and/or source code, so that the
639    user can modify the Library and then relink to produce a modified
640    executable containing the modified Library.  (It is understood
641    that the user who changes the contents of definitions files in the
642    Library will not necessarily be able to recompile the application
643    to use the modified definitions.)
644
645    b) Use a suitable shared library mechanism for linking with the
646    Library.  A suitable mechanism is one that (1) uses at run time a
647    copy of the library already present on the user's computer system,
648    rather than copying library functions into the executable, and (2)
649    will operate properly with a modified version of the library, if
650    the user installs one, as long as the modified version is
651    interface-compatible with the version that the work was made with.
652
653    c) Accompany the work with a written offer, valid for at
654    least three years, to give the same user the materials
655    specified in Subsection 6a, above, for a charge no more
656    than the cost of performing this distribution.
657
658    d) If distribution of the work is made by offering access to copy
659    from a designated place, offer equivalent access to copy the above
660    specified materials from the same place.
661
662    e) Verify that the user has already received a copy of these
663    materials or that you have already sent this user a copy.
664
665  For an executable, the required form of the "work that uses the
666Library" must include any data and utility programs needed for
667reproducing the executable from it.  However, as a special exception,
668the materials to be distributed need not include anything that is
669normally distributed (in either source or binary form) with the major
670components (compiler, kernel, and so on) of the operating system on
671which the executable runs, unless that component itself accompanies
672the executable.
673
674  It may happen that this requirement contradicts the license
675restrictions of other proprietary libraries that do not normally
676accompany the operating system.  Such a contradiction means you cannot
677use both them and the Library together in an executable that you
678distribute.
679
680  7. You may place library facilities that are a work based on the
681Library side-by-side in a single library together with other library
682facilities not covered by this License, and distribute such a combined
683library, provided that the separate distribution of the work based on
684the Library and of the other library facilities is otherwise
685permitted, and provided that you do these two things:
686
687    a) Accompany the combined library with a copy of the same work
688    based on the Library, uncombined with any other library
689    facilities.  This must be distributed under the terms of the
690    Sections above.
691
692    b) Give prominent notice with the combined library of the fact
693    that part of it is a work based on the Library, and explaining
694    where to find the accompanying uncombined form of the same work.
695
696  8. You may not copy, modify, sublicense, link with, or distribute
697the Library except as expressly provided under this License.  Any
698attempt otherwise to copy, modify, sublicense, link with, or
699distribute the Library is void, and will automatically terminate your
700rights under this License.  However, parties who have received copies,
701or rights, from you under this License will not have their licenses
702terminated so long as such parties remain in full compliance.
703
704  9. You are not required to accept this License, since you have not
705signed it.  However, nothing else grants you permission to modify or
706distribute the Library or its derivative works.  These actions are
707prohibited by law if you do not accept this License.  Therefore, by
708modifying or distributing the Library (or any work based on the
709Library), you indicate your acceptance of this License to do so, and
710all its terms and conditions for copying, distributing or modifying
711the Library or works based on it.
712
713  10. Each time you redistribute the Library (or any work based on the
714Library), the recipient automatically receives a license from the
715original licensor to copy, distribute, link with or modify the Library
716subject to these terms and conditions.  You may not impose any further
717restrictions on the recipients' exercise of the rights granted herein.
718You are not responsible for enforcing compliance by third parties with
719this License.
720
721  11. If, as a consequence of a court judgment or allegation of patent
722infringement or for any other reason (not limited to patent issues),
723conditions are imposed on you (whether by court order, agreement or
724otherwise) that contradict the conditions of this License, they do not
725excuse you from the conditions of this License.  If you cannot
726distribute so as to satisfy simultaneously your obligations under this
727License and any other pertinent obligations, then as a consequence you
728may not distribute the Library at all.  For example, if a patent
729license would not permit royalty-free redistribution of the Library by
730all those who receive copies directly or indirectly through you, then
731the only way you could satisfy both it and this License would be to
732refrain entirely from distribution of the Library.
733
734If any portion of this section is held invalid or unenforceable under any
735particular circumstance, the balance of the section is intended to apply,
736and the section as a whole is intended to apply in other circumstances.
737
738It is not the purpose of this section to induce you to infringe any
739patents or other property right claims or to contest validity of any
740such claims; this section has the sole purpose of protecting the
741integrity of the free software distribution system which is
742implemented by public license practices.  Many people have made
743generous contributions to the wide range of software distributed
744through that system in reliance on consistent application of that
745system; it is up to the author/donor to decide if he or she is willing
746to distribute software through any other system and a licensee cannot
747impose that choice.
748
749This section is intended to make thoroughly clear what is believed to
750be a consequence of the rest of this License.
751
752  12. If the distribution and/or use of the Library is restricted in
753certain countries either by patents or by copyrighted interfaces, the
754original copyright holder who places the Library under this License may add
755an explicit geographical distribution limitation excluding those countries,
756so that distribution is permitted only in or among countries not thus
757excluded.  In such case, this License incorporates the limitation as if
758written in the body of this License.
759
760  13. The Free Software Foundation may publish revised and/or new
761versions of the Lesser General Public License from time to time.
762Such new versions will be similar in spirit to the present version,
763but may differ in detail to address new problems or concerns.
764
765Each version is given a distinguishing version number.  If the Library
766specifies a version number of this License which applies to it and
767"any later version", you have the option of following the terms and
768conditions either of that version or of any later version published by
769the Free Software Foundation.  If the Library does not specify a
770license version number, you may choose any version ever published by
771the Free Software Foundation.
772
773  14. If you wish to incorporate parts of the Library into other free
774programs whose distribution conditions are incompatible with these,
775write to the author to ask for permission.  For software which is
776copyrighted by the Free Software Foundation, write to the Free
777Software Foundation; we sometimes make exceptions for this.  Our
778decision will be guided by the two goals of preserving the free status
779of all derivatives of our free software and of promoting the sharing
780and reuse of software generally.
781
782                            NO WARRANTY
783
784  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
785WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
786EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
787OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
788KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
789IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
790PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
791LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
792THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
793
794  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
795WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
796AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
797FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
798CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
799LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
800RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
801FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
802SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
803DAMAGES.
804
805                     END OF TERMS AND CONDITIONS
806
807           How to Apply These Terms to Your New Libraries
808
809  If you develop a new library, and you want it to be of the greatest
810possible use to the public, we recommend making it free software that
811everyone can redistribute and change.  You can do so by permitting
812redistribution under these terms (or, alternatively, under the terms of the
813ordinary General Public License).
814
815  To apply these terms, attach the following notices to the library.  It is
816safest to attach them to the start of each source file to most effectively
817convey the exclusion of warranty; and each file should have at least the
818"copyright" line and a pointer to where the full notice is found.
819
820    <one line to give the library's name and a brief idea of what it does.>
821    Copyright (C) <year>  <name of author>
822
823    This library is free software; you can redistribute it and/or
824    modify it under the terms of the GNU Lesser General Public
825    License as published by the Free Software Foundation; either
826    version 2.1 of the License, or (at your option) any later version.
827
828    This library is distributed in the hope that it will be useful,
829    but WITHOUT ANY WARRANTY; without even the implied warranty of
830    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
831    Lesser General Public License for more details.
832
833    You should have received a copy of the GNU Lesser General Public
834    License along with this library; if not, write to the Free Software
835    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
836
837Also add information on how to contact you by electronic and paper mail.
838
839You should also get your employer (if you work as a programmer) or your
840school, if any, to sign a "copyright disclaimer" for the library, if
841necessary.  Here is a sample; alter the names:
842
843  Yoyodyne, Inc., hereby disclaims all copyright interest in the
844  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
