27                       59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
28 Everyone is permitted to copy and distribute verbatim copies
29 of this license document, but changing it is not allowed.
30
31			    Preamble
32
33  The licenses for most software are designed to take away your
34freedom to share and change it.  By contrast, the GNU General Public
35License is intended to guarantee your freedom to share and change free
36software--to make sure the software is free for all its users.  This
37General Public License applies to most of the Free Software
38Foundation's software and to any other program whose authors commit to
39using it.  (Some other Free Software Foundation software is covered by
40the GNU Library General Public License instead.)  You can apply it to
41your programs, too.
42
43  When we speak of free software, we are referring to freedom, not
44price.  Our General Public Licenses are designed to make sure that you
45have the freedom to distribute copies of free software (and charge for
46this service if you wish), that you receive source code or can get it
47if you want it, that you can change the software or use pieces of it
48in new free programs; and that you know you can do these things.
49
50  To protect your rights, we need to make restrictions that forbid
51anyone to deny you these rights or to ask you to surrender the rights.
52These restrictions translate to certain responsibilities for you if you
53distribute copies of the software, or if you modify it.
54
55  For example, if you distribute copies of such a program, whether
56gratis or for a fee, you must give the recipients all the rights that
57you have.  You must make sure that they, too, receive or can get the
58source code.  And you must show them these terms so they know their
59rights.
60
61  We protect your rights with two steps: (1) copyright the software, and
62(2) offer you this license which gives you legal permission to copy,
63distribute and/or modify the software.
64
65  Also, for each author's protection and ours, we want to make certain
66that everyone understands that there is no warranty for this free
67software.  If the software is modified by someone else and passed on, we
68want its recipients to know that what they have is not the original, so
69that any problems introduced by others will not reflect on the original
70authors' reputations.
71
72  Finally, any free program is threatened constantly by software
73patents.  We wish to avoid the danger that redistributors of a free
74program will individually obtain patent licenses, in effect making the
75program proprietary.  To prevent this, we have made it clear that any
76patent must be licensed for everyone's free use or not licensed at all.
77
78  The precise terms and conditions for copying, distribution and
79modification follow.
80
81		    GNU GENERAL PUBLIC LICENSE
82   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
83
84  0. This License applies to any program or other work which contains
85a notice placed by the copyright holder saying it may be distributed
86under the terms of this General Public License.  The "Program", below,
87refers to any such program or work, and a "work based on the Program"
88means either the Program or any derivative work under copyright law:
89that is to say, a work containing the Program or a portion of it,
90either verbatim or with modifications and/or translated into another
91language.  (Hereinafter, translation is included without limitation in
92the term "modification".)  Each licensee is addressed as "you".
93
94Activities other than copying, distribution and modification are not
95covered by this License; they are outside its scope.  The act of
96running the Program is not restricted, and the output from the Program
97is covered only if its contents constitute a work based on the
98Program (independent of having been made by running the Program).
99Whether that is true depends on what the Program does.
100
101  1. You may copy and distribute verbatim copies of the Program's
102source code as you receive it, in any medium, provided that you
103conspicuously and appropriately publish on each copy an appropriate
104copyright notice and disclaimer of warranty; keep intact all the
105notices that refer to this License and to the absence of any warranty;
106and give any other recipients of the Program a copy of this License
107along with the Program.
108
109You may charge a fee for the physical act of transferring a copy, and
110you may at your option offer warranty protection in exchange for a fee.
111
112  2. You may modify your copy or copies of the Program or any portion
113of it, thus forming a work based on the Program, and copy and
114distribute such modifications or work under the terms of Section 1
115above, provided that you also meet all of these conditions:
116
117    a) You must cause the modified files to carry prominent notices
118    stating that you changed the files and the date of any change.
119
120    b) You must cause any work that you distribute or publish, that in
121    whole or in part contains or is derived from the Program or any
122    part thereof, to be licensed as a whole at no charge to all third
123    parties under the terms of this License.
124
125    c) If the modified program normally reads commands interactively
126    when run, you must cause it, when started running for such
127    interactive use in the most ordinary way, to print or display an
128    announcement including an appropriate copyright notice and a
129    notice that there is no warranty (or else, saying that you provide
130    a warranty) and that users may redistribute the program under
131    these conditions, and telling the user how to view a copy of this
132    License.  (Exception: if the Program itself is interactive but
133    does not normally print such an announcement, your work based on
134    the Program is not required to print an announcement.)
135
136These requirements apply to the modified work as a whole.  If
137identifiable sections of that work are not derived from the Program,
138and can be reasonably considered independent and separate works in
139themselves, then this License, and its terms, do not apply to those
140sections when you distribute them as separate works.  But when you
141distribute the same sections as part of a whole which is a work based
142on the Program, the distribution of the whole must be on the terms of
143this License, whose permissions for other licensees extend to the
144entire whole, and thus to each and every part regardless of who wrote it.
145
146Thus, it is not the intent of this section to claim rights or contest
147your rights to work written entirely by you; rather, the intent is to
148exercise the right to control the distribution of derivative or
149collective works based on the Program.
150
151In addition, mere aggregation of another work not based on the Program
152with the Program (or with a work based on the Program) on a volume of
153a storage or distribution medium does not bring the other work under
154the scope of this License.
155
156  3. You may copy and distribute the Program (or a work based on it,
157under Section 2) in object code or executable form under the terms of
158Sections 1 and 2 above provided that you also do one of the following:
159
160    a) Accompany it with the complete corresponding machine-readable
161    source code, which must be distributed under the terms of Sections
162    1 and 2 above on a medium customarily used for software interchange; or,
163
164    b) Accompany it with a written offer, valid for at least three
165    years, to give any third party, for a charge no more than your
166    cost of physically performing source distribution, a complete
167    machine-readable copy of the corresponding source code, to be
168    distributed under the terms of Sections 1 and 2 above on a medium
169    customarily used for software interchange; or,
170
171    c) Accompany it with the information you received as to the offer
172    to distribute corresponding source code.  (This alternative is
173    allowed only for noncommercial distribution and only if you
174    received the program in object code or executable form with such
175    an offer, in accord with Subsection b above.)
176
177The source code for a work means the preferred form of the work for
178making modifications to it.  For an executable work, complete source
179code means all the source code for all modules it contains, plus any
180associated interface definition files, plus the scripts used to
181control compilation and installation of the executable.  However, as a
182special exception, the source code distributed need not include
183anything that is normally distributed (in either source or binary
184form) with the major components (compiler, kernel, and so on) of the
185operating system on which the executable runs, unless that component
186itself accompanies the executable.
187
188If distribution of executable or object code is made by offering
189access to copy from a designated place, then offering equivalent
190access to copy the source code from the same place counts as
191distribution of the source code, even though third parties are not
192compelled to copy the source along with the object code.
193
194  4. You may not copy, modify, sublicense, or distribute the Program
195except as expressly provided under this License.  Any attempt
196otherwise to copy, modify, sublicense or distribute the Program is
197void, and will automatically terminate your rights under this License.
198However, parties who have received copies, or rights, from you under
199this License will not have their licenses terminated so long as such
200parties remain in full compliance.
201
202  5. You are not required to accept this License, since you have not
203signed it.  However, nothing else grants you permission to modify or
204distribute the Program or its derivative works.  These actions are
205prohibited by law if you do not accept this License.  Therefore, by
206modifying or distributing the Program (or any work based on the
207Program), you indicate your acceptance of this License to do so, and
208all its terms and conditions for copying, distributing or modifying
209the Program or works based on it.
210
211  6. Each time you redistribute the Program (or any work based on the
212Program), the recipient automatically receives a license from the
213original licensor to copy, distribute or modify the Program subject to
214these terms and conditions.  You may not impose any further
215restrictions on the recipients' exercise of the rights granted herein.
216You are not responsible for enforcing compliance by third parties to
217this License.
218
219  7. If, as a consequence of a court judgment or allegation of patent
220infringement or for any other reason (not limited to patent issues),
221conditions are imposed on you (whether by court order, agreement or
222otherwise) that contradict the conditions of this License, they do not
223excuse you from the conditions of this License.  If you cannot
224distribute so as to satisfy simultaneously your obligations under this
225License and any other pertinent obligations, then as a consequence you
226may not distribute the Program at all.  For example, if a patent
227license would not permit royalty-free redistribution of the Program by
228all those who receive copies directly or indirectly through you, then
229the only way you could satisfy both it and this License would be to
230refrain entirely from distribution of the Program.
231
232If any portion of this section is held invalid or unenforceable under
233any particular circumstance, the balance of the section is intended to
234apply and the section as a whole is intended to apply in other
235circumstances.
236
237It is not the purpose of this section to induce you to infringe any
238patents or other property right claims or to contest validity of any
239such claims; this section has the sole purpose of protecting the
240integrity of the free software distribution system, which is
241implemented by public license practices.  Many people have made
242generous contributions to the wide range of software distributed
243through that system in reliance on consistent application of that
244system; it is up to the author/donor to decide if he or she is willing
245to distribute software through any other system and a licensee cannot
246impose that choice.
247
248This section is intended to make thoroughly clear what is believed to
249be a consequence of the rest of this License.
250
251  8. If the distribution and/or use of the Program is restricted in
252certain countries either by patents or by copyrighted interfaces, the
253original copyright holder who places the Program under this License
254may add an explicit geographical distribution limitation excluding
255those countries, so that distribution is permitted only in or among
256countries not thus excluded.  In such case, this License incorporates
257the limitation as if written in the body of this License.
258
259  9. The Free Software Foundation may publish revised and/or new versions
260of the General Public License from time to time.  Such new versions will
261be similar in spirit to the present version, but may differ in detail to
262address new problems or concerns.
263
264Each version is given a distinguishing version number.  If the Program
265specifies a version number of this License which applies to it and "any
266later version", you have the option of following the terms and conditions
267either of that version or of any later version published by the Free
268Software Foundation.  If the Program does not specify a version number of
269this License, you may choose any version ever published by the Free Software
270Foundation.
271
272  10. If you wish to incorporate parts of the Program into other free
273programs whose distribution conditions are different, write to the author
274to ask for permission.  For software which is copyrighted by the Free
275Software Foundation, write to the Free Software Foundation; we sometimes
276make exceptions for this.  Our decision will be guided by the two goals
277of preserving the free status of all derivatives of our free software and
278of promoting the sharing and reuse of software generally.
279
280			    NO WARRANTY
281
282  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
283FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
284OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
285PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
286OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
287MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
288TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
289PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
290REPAIR OR CORRECTION.
291
292  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
293WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
294REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
295INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
296OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
297TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
298YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
299PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
300POSSIBILITY OF SUCH DAMAGES.
301
302		     END OF TERMS AND CONDITIONS
303
304	    How to Apply These Terms to Your New Programs
305
306  If you develop a new program, and you want it to be of the greatest
307possible use to the public, the best way to achieve this is to make it
308free software which everyone can redistribute and change under these terms.
309
310  To do so, attach the following notices to the program.  It is safest
311to attach them to the start of each source file to most effectively
312convey the exclusion of warranty; and each file should have at least
313the "copyright" line and a pointer to where the full notice is found.
314
315    <one line to give the program's name and a brief idea of what it does.>
316    Copyright (C) <year>  <name of author>
317
318    This program is free software; you can redistribute it and/or modify
319    it under the terms of the GNU General Public License as published by
320    the Free Software Foundation; either version 2 of the License, or
321    (at your option) any later version.
322
323    This program is distributed in the hope that it will be useful,
324    but WITHOUT ANY WARRANTY; without even the implied warranty of
325    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
326    GNU General Public License for more details.
327
328    You should have received a copy of the GNU General Public License
329    along with this program; if not, write to the Free Software
330    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
331
332
333Also add information on how to contact you by electronic and paper mail.
334
335If the program is interactive, make it output a short notice like this
336when it starts in an interactive mode:
337
338    Gnomovision version 69, Copyright (C) year name of author
339    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
340    This is free software, and you are welcome to redistribute it
341    under certain conditions; type `show c' for details.
342
343The hypothetical commands `show w' and `show c' should show the appropriate
344parts of the General Public License.  Of course, the commands you use may
345be called something other than `show w' and `show c'; they could even be
346mouse-clicks or menu items--whatever suits your program.
347
348You should also get your employer (if you work as a programmer) or your
349school, if any, to sign a "copyright disclaimer" for the program, if
350necessary.  Here is a sample; alter the names:
351
352  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
353  `Gnomovision' (which makes passes at compilers) written by James Hacker.

357
358This General Public License does not permit incorporating your program into
359proprietary programs.  If your program is a subroutine library, you may
360consider it more useful to permit linking proprietary applications with the
361library.  If this is what you want to do, use the GNU Library General
362Public License instead of this License.

468 of this license document, but changing it is not allowed.
469
470[This is the first released version of the Lesser GPL.  It also counts
471 as the successor of the GNU Library Public License, version 2, hence
472 the version number 2.1.]
473
474                            Preamble
475
476  The licenses for most software are designed to take away your
477freedom to share and change it.  By contrast, the GNU General Public
478Licenses are intended to guarantee your freedom to share and change
479free software--to make sure the software is free for all its users.
480
481  This license, the Lesser General Public License, applies to some
482specially designated software packages--typically libraries--of the
483Free Software Foundation and other authors who decide to use it.  You
484can use it too, but we suggest you first think carefully about whether
485this license or the ordinary General Public License is the better
486strategy to use in any particular case, based on the explanations below.
487
488  When we speak of free software, we are referring to freedom of use,
489not price.  Our General Public Licenses are designed to make sure that
490you have the freedom to distribute copies of free software (and charge
491for this service if you wish); that you receive source code or can get
492it if you want it; that you can change the software and use pieces of
493it in new free programs; and that you are informed that you can do
494these things.
495
496  To protect your rights, we need to make restrictions that forbid
497distributors to deny you these rights or to ask you to surrender these
498rights.  These restrictions translate to certain responsibilities for
499you if you distribute copies of the library or if you modify it.
500
501  For example, if you distribute copies of the library, whether gratis
502or for a fee, you must give the recipients all the rights that we gave
503you.  You must make sure that they, too, receive or can get the source
504code.  If you link other code with the library, you must provide
505complete object files to the recipients, so that they can relink them
506with the library after making changes to the library and recompiling
507it.  And you must show them these terms so they know their rights.
508
509  We protect your rights with a two-step method: (1) we copyright the
510library, and (2) we offer you this license, which gives you legal
511permission to copy, distribute and/or modify the library.
512
513  To protect each distributor, we want to make it very clear that
514there is no warranty for the free library.  Also, if the library is
515modified by someone else and passed on, the recipients should know
516that what they have is not the original version, so that the original
517author's reputation will not be affected by problems that might be
518introduced by others.
519
520  Finally, software patents pose a constant threat to the existence of
521any free program.  We wish to make sure that a company cannot
522effectively restrict the users of a free program by obtaining a
523restrictive license from a patent holder.  Therefore, we insist that
524any patent license obtained for a version of the library must be
525consistent with the full freedom of use specified in this license.
526
527  Most GNU software, including some libraries, is covered by the
528ordinary GNU General Public License.  This license, the GNU Lesser
529General Public License, applies to certain designated libraries, and
530is quite different from the ordinary General Public License.  We use
531this license for certain libraries in order to permit linking those
532libraries into non-free programs.
533
534  When a program is linked with a library, whether statically or using
535a shared library, the combination of the two is legally speaking a
536combined work, a derivative of the original library.  The ordinary
537General Public License therefore permits such linking only if the
538entire combination fits its criteria of freedom.  The Lesser General
539Public License permits more lax criteria for linking other code with
540the library.
541
542  We call this license the "Lesser" General Public License because it
543does Less to protect the user's freedom than the ordinary General
544Public License.  It also provides other free software developers Less
545of an advantage over competing non-free programs.  These disadvantages
546are the reason we use the ordinary General Public License for many
547libraries.  However, the Lesser license provides advantages in certain
548special circumstances.
549
550  For example, on rare occasions, there may be a special need to
551encourage the widest possible use of a certain library, so that it becomes
552a de-facto standard.  To achieve this, non-free programs must be
553allowed to use the library.  A more frequent case is that a free
554library does the same job as widely used non-free libraries.  In this
555case, there is little to gain by limiting the free library to free
556software only, so we use the Lesser General Public License.
557
558  In other cases, permission to use a particular library in non-free
559programs enables a greater number of people to use a large body of
560free software.  For example, permission to use the GNU C Library in
561non-free programs enables many more people to use the whole GNU
562operating system, as well as its variant, the GNU/Linux operating
563system.
564
565  Although the Lesser General Public License is Less protective of the
566users' freedom, it does ensure that the user of a program that is
567linked with the Library has the freedom and the wherewithal to run
568that program using a modified version of the Library.
569
570  The precise terms and conditions for copying, distribution and
571modification follow.  Pay close attention to the difference between a
572"work based on the library" and a "work that uses the library".  The
573former contains code derived from the library, whereas the latter must
574be combined with the library in order to run.
575
576                  GNU LESSER GENERAL PUBLIC LICENSE
577   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
578
579  0. This License Agreement applies to any software library or other
580program which contains a notice placed by the copyright holder or
581other authorized party saying it may be distributed under the terms of
582this Lesser General Public License (also called "this License").
583Each licensee is addressed as "you".
584
585  A "library" means a collection of software functions and/or data
586prepared so as to be conveniently linked with application programs
587(which use some of those functions and data) to form executables.
588
589  The "Library", below, refers to any such software library or work
590which has been distributed under these terms.  A "work based on the
591Library" means either the Library or any derivative work under
592copyright law: that is to say, a work containing the Library or a
593portion of it, either verbatim or with modifications and/or translated
594straightforwardly into another language.  (Hereinafter, translation is
595included without limitation in the term "modification".)
596
597  "Source code" for a work means the preferred form of the work for
598making modifications to it.  For a library, complete source code means
599all the source code for all modules it contains, plus any associated
600interface definition files, plus the scripts used to control compilation
601and installation of the library.
602
603  Activities other than copying, distribution and modification are not
604covered by this License; they are outside its scope.  The act of
605running a program using the Library is not restricted, and output from
606such a program is covered only if its contents constitute a work based
607on the Library (independent of the use of the Library in a tool for
608writing it).  Whether that is true depends on what the Library does
609and what the program that uses the Library does.
610
611  1. You may copy and distribute verbatim copies of the Library's
612complete source code as you receive it, in any medium, provided that
613you conspicuously and appropriately publish on each copy an
614appropriate copyright notice and disclaimer of warranty; keep intact
615all the notices that refer to this License and to the absence of any
616warranty; and distribute a copy of this License along with the
617Library.
618
619  You may charge a fee for the physical act of transferring a copy,
620and you may at your option offer warranty protection in exchange for a
621fee.
622
623  2. You may modify your copy or copies of the Library or any portion
624of it, thus forming a work based on the Library, and copy and
625distribute such modifications or work under the terms of Section 1
626above, provided that you also meet all of these conditions:
627
628    a) The modified work must itself be a software library.
629
630    b) You must cause the files modified to carry prominent notices
631    stating that you changed the files and the date of any change.
632
633    c) You must cause the whole of the work to be licensed at no
634    charge to all third parties under the terms of this License.
635
636    d) If a facility in the modified Library refers to a function or a
637    table of data to be supplied by an application program that uses
638    the facility, other than as an argument passed when the facility
639    is invoked, then you must make a good faith effort to ensure that,
640    in the event an application does not supply such function or
641    table, the facility still operates, and performs whatever part of
642    its purpose remains meaningful.
643
644    (For example, a function in a library to compute square roots has
645    a purpose that is entirely well-defined independent of the
646    application.  Therefore, Subsection 2d requires that any
647    application-supplied function or table used by this function must
648    be optional: if the application does not supply it, the square
649    root function must still compute square roots.)
650
651These requirements apply to the modified work as a whole.  If
652identifiable sections of that work are not derived from the Library,
653and can be reasonably considered independent and separate works in
654themselves, then this License, and its terms, do not apply to those
655sections when you distribute them as separate works.  But when you
656distribute the same sections as part of a whole which is a work based
657on the Library, the distribution of the whole must be on the terms of
658this License, whose permissions for other licensees extend to the
659entire whole, and thus to each and every part regardless of who wrote
660it.
661
662Thus, it is not the intent of this section to claim rights or contest
663your rights to work written entirely by you; rather, the intent is to
664exercise the right to control the distribution of derivative or
665collective works based on the Library.
666
667In addition, mere aggregation of another work not based on the Library
668with the Library (or with a work based on the Library) on a volume of
669a storage or distribution medium does not bring the other work under
670the scope of this License.
671
672  3. You may opt to apply the terms of the ordinary GNU General Public
673License instead of this License to a given copy of the Library.  To do
674this, you must alter all the notices that refer to this License, so
675that they refer to the ordinary GNU General Public License, version 2,
676instead of to this License.  (If a newer version than version 2 of the
677ordinary GNU General Public License has appeared, then you can specify
678that version instead if you wish.)  Do not make any other change in
679these notices.
680
681  Once this change is made in a given copy, it is irreversible for
682that copy, so the ordinary GNU General Public License applies to all
683subsequent copies and derivative works made from that copy.
684
685  This option is useful when you wish to copy part of the code of
686the Library into a program that is not a library.
687
688  4. You may copy and distribute the Library (or a portion or
689derivative of it, under Section 2) in object code or executable form
690under the terms of Sections 1 and 2 above provided that you accompany
691it with the complete corresponding machine-readable source code, which
692must be distributed under the terms of Sections 1 and 2 above on a
693medium customarily used for software interchange.
694
695  If distribution of object code is made by offering access to copy
696from a designated place, then offering equivalent access to copy the
697source code from the same place satisfies the requirement to
698distribute the source code, even though third parties are not
699compelled to copy the source along with the object code.
700
701  5. A program that contains no derivative of any portion of the
702Library, but is designed to work with the Library by being compiled or
703linked with it, is called a "work that uses the Library".  Such a
704work, in isolation, is not a derivative work of the Library, and
705therefore falls outside the scope of this License.
706
707  However, linking a "work that uses the Library" with the Library
708creates an executable that is a derivative of the Library (because it
709contains portions of the Library), rather than a "work that uses the
710library".  The executable is therefore covered by this License.
711Section 6 states terms for distribution of such executables.
712
713  When a "work that uses the Library" uses material from a header file
714that is part of the Library, the object code for the work may be a
715derivative work of the Library even though the source code is not.
716Whether this is true is especially significant if the work can be
717linked without the Library, or if the work is itself a library.  The
718threshold for this to be true is not precisely defined by law.
719
720  If such an object file uses only numerical parameters, data
721structure layouts and accessors, and small macros and small inline
722functions (ten lines or less in length), then the use of the object
723file is unrestricted, regardless of whether it is legally a derivative
724work.  (Executables containing this object code plus portions of the
725Library will still fall under Section 6.)
726
727  Otherwise, if the work is a derivative of the Library, you may
728distribute the object code for the work under the terms of Section 6.
729Any executables containing that work also fall under Section 6,
730whether or not they are linked directly with the Library itself.
731
732  6. As an exception to the Sections above, you may also combine or
733link a "work that uses the Library" with the Library to produce a
734work containing portions of the Library, and distribute that work
735under terms of your choice, provided that the terms permit
736modification of the work for the customer's own use and reverse
737engineering for debugging such modifications.
738
739  You must give prominent notice with each copy of the work that the
740Library is used in it and that the Library and its use are covered by
741this License.  You must supply a copy of this License.  If the work
742during execution displays copyright notices, you must include the
743copyright notice for the Library among them, as well as a reference
744directing the user to the copy of this License.  Also, you must do one
745of these things:
746
747    a) Accompany the work with the complete corresponding
748    machine-readable source code for the Library including whatever
749    changes were used in the work (which must be distributed under
750    Sections 1 and 2 above); and, if the work is an executable linked
751    with the Library, with the complete machine-readable "work that
752    uses the Library", as object code and/or source code, so that the
753    user can modify the Library and then relink to produce a modified
754    executable containing the modified Library.  (It is understood
755    that the user who changes the contents of definitions files in the
756    Library will not necessarily be able to recompile the application
757    to use the modified definitions.)
758
759    b) Use a suitable shared library mechanism for linking with the
760    Library.  A suitable mechanism is one that (1) uses at run time a
761    copy of the library already present on the user's computer system,
762    rather than copying library functions into the executable, and (2)
763    will operate properly with a modified version of the library, if
764    the user installs one, as long as the modified version is
765    interface-compatible with the version that the work was made with.
766
767    c) Accompany the work with a written offer, valid for at
768    least three years, to give the same user the materials
769    specified in Subsection 6a, above, for a charge no more
770    than the cost of performing this distribution.
771
772    d) If distribution of the work is made by offering access to copy
773    from a designated place, offer equivalent access to copy the above
774    specified materials from the same place.
775
776    e) Verify that the user has already received a copy of these
777    materials or that you have already sent this user a copy.
778
779  For an executable, the required form of the "work that uses the
780Library" must include any data and utility programs needed for
781reproducing the executable from it.  However, as a special exception,
782the materials to be distributed need not include anything that is
783normally distributed (in either source or binary form) with the major
784components (compiler, kernel, and so on) of the operating system on
785which the executable runs, unless that component itself accompanies
786the executable.
787
788  It may happen that this requirement contradicts the license
789restrictions of other proprietary libraries that do not normally
790accompany the operating system.  Such a contradiction means you cannot
791use both them and the Library together in an executable that you
792distribute.
793
794  7. You may place library facilities that are a work based on the
795Library side-by-side in a single library together with other library
796facilities not covered by this License, and distribute such a combined
797library, provided that the separate distribution of the work based on
798the Library and of the other library facilities is otherwise
799permitted, and provided that you do these two things:
800
801    a) Accompany the combined library with a copy of the same work
802    based on the Library, uncombined with any other library
803    facilities.  This must be distributed under the terms of the
804    Sections above.
805
806    b) Give prominent notice with the combined library of the fact
807    that part of it is a work based on the Library, and explaining
808    where to find the accompanying uncombined form of the same work.
809
810  8. You may not copy, modify, sublicense, link with, or distribute
811the Library except as expressly provided under this License.  Any
812attempt otherwise to copy, modify, sublicense, link with, or
813distribute the Library is void, and will automatically terminate your
814rights under this License.  However, parties who have received copies,
815or rights, from you under this License will not have their licenses
816terminated so long as such parties remain in full compliance.
817
818  9. You are not required to accept this License, since you have not
819signed it.  However, nothing else grants you permission to modify or
820distribute the Library or its derivative works.  These actions are
821prohibited by law if you do not accept this License.  Therefore, by
822modifying or distributing the Library (or any work based on the
823Library), you indicate your acceptance of this License to do so, and
824all its terms and conditions for copying, distributing or modifying
825the Library or works based on it.
826
827  10. Each time you redistribute the Library (or any work based on the
828Library), the recipient automatically receives a license from the
829original licensor to copy, distribute, link with or modify the Library
830subject to these terms and conditions.  You may not impose any further
831restrictions on the recipients' exercise of the rights granted herein.
832You are not responsible for enforcing compliance by third parties with
833this License.
834
835  11. If, as a consequence of a court judgment or allegation of patent
836infringement or for any other reason (not limited to patent issues),
837conditions are imposed on you (whether by court order, agreement or
838otherwise) that contradict the conditions of this License, they do not
839excuse you from the conditions of this License.  If you cannot
840distribute so as to satisfy simultaneously your obligations under this
841License and any other pertinent obligations, then as a consequence you
842may not distribute the Library at all.  For example, if a patent
843license would not permit royalty-free redistribution of the Library by
844all those who receive copies directly or indirectly through you, then
845the only way you could satisfy both it and this License would be to
846refrain entirely from distribution of the Library.
847
848If any portion of this section is held invalid or unenforceable under any
849particular circumstance, the balance of the section is intended to apply,
850and the section as a whole is intended to apply in other circumstances.
851
852It is not the purpose of this section to induce you to infringe any
853patents or other property right claims or to contest validity of any
854such claims; this section has the sole purpose of protecting the
855integrity of the free software distribution system which is
856implemented by public license practices.  Many people have made
857generous contributions to the wide range of software distributed
858through that system in reliance on consistent application of that
859system; it is up to the author/donor to decide if he or she is willing
860to distribute software through any other system and a licensee cannot
861impose that choice.
862
863This section is intended to make thoroughly clear what is believed to
864be a consequence of the rest of this License.
865
866  12. If the distribution and/or use of the Library is restricted in
867certain countries either by patents or by copyrighted interfaces, the
868original copyright holder who places the Library under this License may add
869an explicit geographical distribution limitation excluding those countries,
870so that distribution is permitted only in or among countries not thus
871excluded.  In such case, this License incorporates the limitation as if
872written in the body of this License.
873
874  13. The Free Software Foundation may publish revised and/or new
875versions of the Lesser General Public License from time to time.
876Such new versions will be similar in spirit to the present version,
877but may differ in detail to address new problems or concerns.
878
879Each version is given a distinguishing version number.  If the Library
880specifies a version number of this License which applies to it and
881"any later version", you have the option of following the terms and
882conditions either of that version or of any later version published by
883the Free Software Foundation.  If the Library does not specify a
884license version number, you may choose any version ever published by
885the Free Software Foundation.
886
887  14. If you wish to incorporate parts of the Library into other free
888programs whose distribution conditions are incompatible with these,
889write to the author to ask for permission.  For software which is
890copyrighted by the Free Software Foundation, write to the Free
891Software Foundation; we sometimes make exceptions for this.  Our
892decision will be guided by the two goals of preserving the free status
893of all derivatives of our free software and of promoting the sharing
894and reuse of software generally.
895
896                            NO WARRANTY
897
898  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
899WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
900EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
901OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
902KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
903IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
904PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
905LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
906THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
907
908  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
909WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
910AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
911FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
912CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
913LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
914RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
915FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
916SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
917DAMAGES.
918
919                     END OF TERMS AND CONDITIONS
920
921           How to Apply These Terms to Your New Libraries
922
923  If you develop a new library, and you want it to be of the greatest
924possible use to the public, we recommend making it free software that
925everyone can redistribute and change.  You can do so by permitting
926redistribution under these terms (or, alternatively, under the terms of the
927ordinary General Public License).
928
929  To apply these terms, attach the following notices to the library.  It is
930safest to attach them to the start of each source file to most effectively
931convey the exclusion of warranty; and each file should have at least the
932"copyright" line and a pointer to where the full notice is found.
933
934    <one line to give the library's name and a brief idea of what it does.>
935    Copyright (C) <year>  <name of author>
936
937    This library is free software; you can redistribute it and/or
938    modify it under the terms of the GNU Lesser General Public
939    License as published by the Free Software Foundation; either
940    version 2.1 of the License, or (at your option) any later version.
941
942    This library is distributed in the hope that it will be useful,
943    but WITHOUT ANY WARRANTY; without even the implied warranty of
944    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
945    Lesser General Public License for more details.
946
947    You should have received a copy of the GNU Lesser General Public
948    License along with this library; if not, write to the Free Software
949    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA
950
951Also add information on how to contact you by electronic and paper mail.
952
953You should also get your employer (if you work as a programmer) or your
954school, if any, to sign a "copyright disclaimer" for the library, if
955necessary.  Here is a sample; alter the names:
956
957  Yoyodyne, Inc., hereby disclaims all copyright interest in the
958  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
