31 Everyone is permitted to copy and distribute verbatim copies
32 of this license document, but changing it is not allowed.
33
34			    Preamble
35
36  The licenses for most software are designed to take away your
37freedom to share and change it.  By contrast, the GNU General Public
38License is intended to guarantee your freedom to share and change free
39software--to make sure the software is free for all its users.  This
40General Public License applies to most of the Free Software
41Foundation's software and to any other program whose authors commit to
42using it.  (Some other Free Software Foundation software is covered by
43the GNU Library General Public License instead.)  You can apply it to
44your programs, too.
45
46  When we speak of free software, we are referring to freedom, not
47price.  Our General Public Licenses are designed to make sure that you
48have the freedom to distribute copies of free software (and charge for
49this service if you wish), that you receive source code or can get it
50if you want it, that you can change the software or use pieces of it
51in new free programs; and that you know you can do these things.
52
53  To protect your rights, we need to make restrictions that forbid
54anyone to deny you these rights or to ask you to surrender the rights.
55These restrictions translate to certain responsibilities for you if you
56distribute copies of the software, or if you modify it.
57
58  For example, if you distribute copies of such a program, whether
59gratis or for a fee, you must give the recipients all the rights that
60you have.  You must make sure that they, too, receive or can get the
61source code.  And you must show them these terms so they know their
62rights.
63
64  We protect your rights with two steps: (1) copyright the software, and
65(2) offer you this license which gives you legal permission to copy,
66distribute and/or modify the software.
67
68  Also, for each author's protection and ours, we want to make certain
69that everyone understands that there is no warranty for this free
70software.  If the software is modified by someone else and passed on, we
71want its recipients to know that what they have is not the original, so
72that any problems introduced by others will not reflect on the original
73authors' reputations.
74
75  Finally, any free program is threatened constantly by software
76patents.  We wish to avoid the danger that redistributors of a free
77program will individually obtain patent licenses, in effect making the
78program proprietary.  To prevent this, we have made it clear that any
79patent must be licensed for everyone's free use or not licensed at all.
80
81  The precise terms and conditions for copying, distribution and
82modification follow.
83
84		    GNU GENERAL PUBLIC LICENSE
85   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
86
87  0. This License applies to any program or other work which contains
88a notice placed by the copyright holder saying it may be distributed
89under the terms of this General Public License.  The "Program", below,
90refers to any such program or work, and a "work based on the Program"
91means either the Program or any derivative work under copyright law:
92that is to say, a work containing the Program or a portion of it,
93either verbatim or with modifications and/or translated into another
94language.  (Hereinafter, translation is included without limitation in
95the term "modification".)  Each licensee is addressed as "you".
96
97Activities other than copying, distribution and modification are not
98covered by this License; they are outside its scope.  The act of
99running the Program is not restricted, and the output from the Program
100is covered only if its contents constitute a work based on the
101Program (independent of having been made by running the Program).
102Whether that is true depends on what the Program does.
103
104  1. You may copy and distribute verbatim copies of the Program's
105source code as you receive it, in any medium, provided that you
106conspicuously and appropriately publish on each copy an appropriate
107copyright notice and disclaimer of warranty; keep intact all the
108notices that refer to this License and to the absence of any warranty;
109and give any other recipients of the Program a copy of this License
110along with the Program.
111
112You may charge a fee for the physical act of transferring a copy, and
113you may at your option offer warranty protection in exchange for a fee.
114
115  2. You may modify your copy or copies of the Program or any portion
116of it, thus forming a work based on the Program, and copy and
117distribute such modifications or work under the terms of Section 1
118above, provided that you also meet all of these conditions:
119
120    a) You must cause the modified files to carry prominent notices
121    stating that you changed the files and the date of any change.
122
123    b) You must cause any work that you distribute or publish, that in
124    whole or in part contains or is derived from the Program or any
125    part thereof, to be licensed as a whole at no charge to all third
126    parties under the terms of this License.
127
128    c) If the modified program normally reads commands interactively
129    when run, you must cause it, when started running for such
130    interactive use in the most ordinary way, to print or display an
131    announcement including an appropriate copyright notice and a
132    notice that there is no warranty (or else, saying that you provide
133    a warranty) and that users may redistribute the program under
134    these conditions, and telling the user how to view a copy of this
135    License.  (Exception: if the Program itself is interactive but
136    does not normally print such an announcement, your work based on
137    the Program is not required to print an announcement.)
138
139These requirements apply to the modified work as a whole.  If
140identifiable sections of that work are not derived from the Program,
141and can be reasonably considered independent and separate works in
142themselves, then this License, and its terms, do not apply to those
143sections when you distribute them as separate works.  But when you
144distribute the same sections as part of a whole which is a work based
145on the Program, the distribution of the whole must be on the terms of
146this License, whose permissions for other licensees extend to the
147entire whole, and thus to each and every part regardless of who wrote it.
148
149Thus, it is not the intent of this section to claim rights or contest
150your rights to work written entirely by you; rather, the intent is to
151exercise the right to control the distribution of derivative or
152collective works based on the Program.
153
154In addition, mere aggregation of another work not based on the Program
155with the Program (or with a work based on the Program) on a volume of
156a storage or distribution medium does not bring the other work under
157the scope of this License.
158
159  3. You may copy and distribute the Program (or a work based on it,
160under Section 2) in object code or executable form under the terms of
161Sections 1 and 2 above provided that you also do one of the following:
162
163    a) Accompany it with the complete corresponding machine-readable
164    source code, which must be distributed under the terms of Sections
165    1 and 2 above on a medium customarily used for software interchange; or,
166
167    b) Accompany it with a written offer, valid for at least three
168    years, to give any third party, for a charge no more than your
169    cost of physically performing source distribution, a complete
170    machine-readable copy of the corresponding source code, to be
171    distributed under the terms of Sections 1 and 2 above on a medium
172    customarily used for software interchange; or,
173
174    c) Accompany it with the information you received as to the offer
175    to distribute corresponding source code.  (This alternative is
176    allowed only for noncommercial distribution and only if you
177    received the program in object code or executable form with such
178    an offer, in accord with Subsection b above.)
179
180The source code for a work means the preferred form of the work for
181making modifications to it.  For an executable work, complete source
182code means all the source code for all modules it contains, plus any
183associated interface definition files, plus the scripts used to
184control compilation and installation of the executable.  However, as a
185special exception, the source code distributed need not include
186anything that is normally distributed (in either source or binary
187form) with the major components (compiler, kernel, and so on) of the
188operating system on which the executable runs, unless that component
189itself accompanies the executable.
190
191If distribution of executable or object code is made by offering
192access to copy from a designated place, then offering equivalent
193access to copy the source code from the same place counts as
194distribution of the source code, even though third parties are not
195compelled to copy the source along with the object code.
196
197  4. You may not copy, modify, sublicense, or distribute the Program
198except as expressly provided under this License.  Any attempt
199otherwise to copy, modify, sublicense or distribute the Program is
200void, and will automatically terminate your rights under this License.
201However, parties who have received copies, or rights, from you under
202this License will not have their licenses terminated so long as such
203parties remain in full compliance.
204
205  5. You are not required to accept this License, since you have not
206signed it.  However, nothing else grants you permission to modify or
207distribute the Program or its derivative works.  These actions are
208prohibited by law if you do not accept this License.  Therefore, by
209modifying or distributing the Program (or any work based on the
210Program), you indicate your acceptance of this License to do so, and
211all its terms and conditions for copying, distributing or modifying
212the Program or works based on it.
213
214  6. Each time you redistribute the Program (or any work based on the
215Program), the recipient automatically receives a license from the
216original licensor to copy, distribute or modify the Program subject to
217these terms and conditions.  You may not impose any further
218restrictions on the recipients' exercise of the rights granted herein.
219You are not responsible for enforcing compliance by third parties to
220this License.
221
222  7. If, as a consequence of a court judgment or allegation of patent
223infringement or for any other reason (not limited to patent issues),
224conditions are imposed on you (whether by court order, agreement or
225otherwise) that contradict the conditions of this License, they do not
226excuse you from the conditions of this License.  If you cannot
227distribute so as to satisfy simultaneously your obligations under this
228License and any other pertinent obligations, then as a consequence you
229may not distribute the Program at all.  For example, if a patent
230license would not permit royalty-free redistribution of the Program by
231all those who receive copies directly or indirectly through you, then
232the only way you could satisfy both it and this License would be to
233refrain entirely from distribution of the Program.
234
235If any portion of this section is held invalid or unenforceable under
236any particular circumstance, the balance of the section is intended to
237apply and the section as a whole is intended to apply in other
238circumstances.
239
240It is not the purpose of this section to induce you to infringe any
241patents or other property right claims or to contest validity of any
242such claims; this section has the sole purpose of protecting the
243integrity of the free software distribution system, which is
244implemented by public license practices.  Many people have made
245generous contributions to the wide range of software distributed
246through that system in reliance on consistent application of that
247system; it is up to the author/donor to decide if he or she is willing
248to distribute software through any other system and a licensee cannot
249impose that choice.
250
251This section is intended to make thoroughly clear what is believed to
252be a consequence of the rest of this License.
253
254  8. If the distribution and/or use of the Program is restricted in
255certain countries either by patents or by copyrighted interfaces, the
256original copyright holder who places the Program under this License
257may add an explicit geographical distribution limitation excluding
258those countries, so that distribution is permitted only in or among
259countries not thus excluded.  In such case, this License incorporates
260the limitation as if written in the body of this License.
261
262  9. The Free Software Foundation may publish revised and/or new versions
263of the General Public License from time to time.  Such new versions will
264be similar in spirit to the present version, but may differ in detail to
265address new problems or concerns.
266
267Each version is given a distinguishing version number.  If the Program
268specifies a version number of this License which applies to it and "any
269later version", you have the option of following the terms and conditions
270either of that version or of any later version published by the Free
271Software Foundation.  If the Program does not specify a version number of
272this License, you may choose any version ever published by the Free Software
273Foundation.
274
275  10. If you wish to incorporate parts of the Program into other free
276programs whose distribution conditions are different, write to the author
277to ask for permission.  For software which is copyrighted by the Free
278Software Foundation, write to the Free Software Foundation; we sometimes
279make exceptions for this.  Our decision will be guided by the two goals
280of preserving the free status of all derivatives of our free software and
281of promoting the sharing and reuse of software generally.
282
283			    NO WARRANTY
284
285  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
286FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
287OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
288PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
289OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
290MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
291TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
292PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
293REPAIR OR CORRECTION.
294
295  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
296WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
297REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
298INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
299OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
300TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
301YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
302PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
303POSSIBILITY OF SUCH DAMAGES.
304
305		     END OF TERMS AND CONDITIONS
306
307	    How to Apply These Terms to Your New Programs
308
309  If you develop a new program, and you want it to be of the greatest
310possible use to the public, the best way to achieve this is to make it
311free software which everyone can redistribute and change under these terms.
312
313  To do so, attach the following notices to the program.  It is safest
314to attach them to the start of each source file to most effectively
315convey the exclusion of warranty; and each file should have at least
316the "copyright" line and a pointer to where the full notice is found.
317
318    <one line to give the program's name and a brief idea of what it does.>
319    Copyright (C) <year>  <name of author>
320
321    This program is free software; you can redistribute it and/or modify
322    it under the terms of the GNU General Public License as published by
323    the Free Software Foundation; either version 2 of the License, or
324    (at your option) any later version.
325
326    This program is distributed in the hope that it will be useful,
327    but WITHOUT ANY WARRANTY; without even the implied warranty of
328    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
329    GNU General Public License for more details.
330
331    You should have received a copy of the GNU General Public License
332    along with this program; if not, write to the Free Software
333    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
334
335
336Also add information on how to contact you by electronic and paper mail.
337
338If the program is interactive, make it output a short notice like this
339when it starts in an interactive mode:
340
341    Gnomovision version 69, Copyright (C) year  name of author
342    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
343    This is free software, and you are welcome to redistribute it
344    under certain conditions; type `show c' for details.
345
346The hypothetical commands `show w' and `show c' should show the appropriate
347parts of the General Public License.  Of course, the commands you use may
348be called something other than `show w' and `show c'; they could even be
349mouse-clicks or menu items--whatever suits your program.
350
351You should also get your employer (if you work as a programmer) or your
352school, if any, to sign a "copyright disclaimer" for the program, if
353necessary.  Here is a sample; alter the names:
354
355  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
356  `Gnomovision' (which makes passes at compilers) written by James Hacker.

360
361This General Public License does not permit incorporating your program into
362proprietary programs.  If your program is a subroutine library, you may
363consider it more useful to permit linking proprietary applications with the
364library.  If this is what you want to do, use the GNU Library General
365Public License instead of this License.

374 Everyone is permitted to copy and distribute verbatim copies
375 of this license document, but changing it is not allowed.
376
377[This is the first released version of the library GPL.  It is
378 numbered 2 because it goes with version 2 of the ordinary GPL.]
379
380			    Preamble
381
382  The licenses for most software are designed to take away your
383freedom to share and change it.  By contrast, the GNU General Public
384Licenses are intended to guarantee your freedom to share and change
385free software--to make sure the software is free for all its users.
386
387  This license, the Library General Public License, applies to some
388specially designated Free Software Foundation software, and to any
389other libraries whose authors decide to use it.  You can use it for
390your libraries, too.
391
392  When we speak of free software, we are referring to freedom, not
393price.  Our General Public Licenses are designed to make sure that you
394have the freedom to distribute copies of free software (and charge for
395this service if you wish), that you receive source code or can get it
396if you want it, that you can change the software or use pieces of it
397in new free programs; and that you know you can do these things.
398
399  To protect your rights, we need to make restrictions that forbid
400anyone to deny you these rights or to ask you to surrender the rights.
401These restrictions translate to certain responsibilities for you if
402you distribute copies of the library, or if you modify it.
403
404  For example, if you distribute copies of the library, whether gratis
405or for a fee, you must give the recipients all the rights that we gave
406you.  You must make sure that they, too, receive or can get the source
407code.  If you link a program with the library, you must provide
408complete object files to the recipients so that they can relink them
409with the library, after making changes to the library and recompiling
410it.  And you must show them these terms so they know their rights.
411
412  Our method of protecting your rights has two steps: (1) copyright
413the library, and (2) offer you this license which gives you legal
414permission to copy, distribute and/or modify the library.
415
416  Also, for each distributor's protection, we want to make certain
417that everyone understands that there is no warranty for this free
418library.  If the library is modified by someone else and passed on, we
419want its recipients to know that what they have is not the original
420version, so that any problems introduced by others will not reflect on
421the original authors' reputations.
422
423  Finally, any free program is threatened constantly by software
424patents.  We wish to avoid the danger that companies distributing free
425software will individually obtain patent licenses, thus in effect
426transforming the program into proprietary software.  To prevent this,
427we have made it clear that any patent must be licensed for everyone's
428free use or not licensed at all.
429
430  Most GNU software, including some libraries, is covered by the ordinary
431GNU General Public License, which was designed for utility programs.  This
432license, the GNU Library General Public License, applies to certain
433designated libraries.  This license is quite different from the ordinary
434one; be sure to read it in full, and don't assume that anything in it is
435the same as in the ordinary license.
436
437  The reason we have a separate public license for some libraries is that
438they blur the distinction we usually make between modifying or adding to a
439program and simply using it.  Linking a program with a library, without
440changing the library, is in some sense simply using the library, and is
441analogous to running a utility program or application program.  However, in
442a textual and legal sense, the linked executable is a combined work, a
443derivative of the original library, and the ordinary General Public License
444treats it as such.
445
446  Because of this blurred distinction, using the ordinary General
447Public License for libraries did not effectively promote software
448sharing, because most developers did not use the libraries.  We
449concluded that weaker conditions might promote sharing better.
450
451  However, unrestricted linking of non-free programs would deprive the
452users of those programs of all benefit from the free status of the
453libraries themselves.  This Library General Public License is intended to
454permit developers of non-free programs to use free libraries, while
455preserving your freedom as a user of such programs to change the free
456libraries that are incorporated in them.  (We have not seen how to achieve
457this as regards changes in header files, but we have achieved it as regards
458changes in the actual functions of the Library.)  The hope is that this
459will lead to faster development of free libraries.
460
461  The precise terms and conditions for copying, distribution and
462modification follow.  Pay close attention to the difference between a
463"work based on the library" and a "work that uses the library".  The
464former contains code derived from the library, while the latter only
465works together with the library.
466
467  Note that it is possible for a library to be covered by the ordinary
468General Public License rather than by this special one.
469
470		  GNU LIBRARY GENERAL PUBLIC LICENSE
471   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
472
473  0. This License Agreement applies to any software library which
474contains a notice placed by the copyright holder or other authorized
475party saying it may be distributed under the terms of this Library
476General Public License (also called "this License").  Each licensee is
477addressed as "you".
478
479  A "library" means a collection of software functions and/or data
480prepared so as to be conveniently linked with application programs
481(which use some of those functions and data) to form executables.
482
483  The "Library", below, refers to any such software library or work
484which has been distributed under these terms.  A "work based on the
485Library" means either the Library or any derivative work under
486copyright law: that is to say, a work containing the Library or a
487portion of it, either verbatim or with modifications and/or translated
488straightforwardly into another language.  (Hereinafter, translation is
489included without limitation in the term "modification".)
490
491  "Source code" for a work means the preferred form of the work for
492making modifications to it.  For a library, complete source code means
493all the source code for all modules it contains, plus any associated
494interface definition files, plus the scripts used to control compilation
495and installation of the library.
496
497  Activities other than copying, distribution and modification are not
498covered by this License; they are outside its scope.  The act of
499running a program using the Library is not restricted, and output from
500such a program is covered only if its contents constitute a work based
501on the Library (independent of the use of the Library in a tool for
502writing it).  Whether that is true depends on what the Library does
503and what the program that uses the Library does.
504  
505  1. You may copy and distribute verbatim copies of the Library's
506complete source code as you receive it, in any medium, provided that
507you conspicuously and appropriately publish on each copy an
508appropriate copyright notice and disclaimer of warranty; keep intact
509all the notices that refer to this License and to the absence of any
510warranty; and distribute a copy of this License along with the
511Library.
512
513  You may charge a fee for the physical act of transferring a copy,
514and you may at your option offer warranty protection in exchange for a
515fee.
516
517  2. You may modify your copy or copies of the Library or any portion
518of it, thus forming a work based on the Library, and copy and
519distribute such modifications or work under the terms of Section 1
520above, provided that you also meet all of these conditions:
521
522    a) The modified work must itself be a software library.
523
524    b) You must cause the files modified to carry prominent notices
525    stating that you changed the files and the date of any change.
526
527    c) You must cause the whole of the work to be licensed at no
528    charge to all third parties under the terms of this License.
529
530    d) If a facility in the modified Library refers to a function or a
531    table of data to be supplied by an application program that uses
532    the facility, other than as an argument passed when the facility
533    is invoked, then you must make a good faith effort to ensure that,
534    in the event an application does not supply such function or
535    table, the facility still operates, and performs whatever part of
536    its purpose remains meaningful.
537
538    (For example, a function in a library to compute square roots has
539    a purpose that is entirely well-defined independent of the
540    application.  Therefore, Subsection 2d requires that any
541    application-supplied function or table used by this function must
542    be optional: if the application does not supply it, the square
543    root function must still compute square roots.)
544
545These requirements apply to the modified work as a whole.  If
546identifiable sections of that work are not derived from the Library,
547and can be reasonably considered independent and separate works in
548themselves, then this License, and its terms, do not apply to those
549sections when you distribute them as separate works.  But when you
550distribute the same sections as part of a whole which is a work based
551on the Library, the distribution of the whole must be on the terms of
552this License, whose permissions for other licensees extend to the
553entire whole, and thus to each and every part regardless of who wrote
554it.
555
556Thus, it is not the intent of this section to claim rights or contest
557your rights to work written entirely by you; rather, the intent is to
558exercise the right to control the distribution of derivative or
559collective works based on the Library.
560
561In addition, mere aggregation of another work not based on the Library
562with the Library (or with a work based on the Library) on a volume of
563a storage or distribution medium does not bring the other work under
564the scope of this License.
565
566  3. You may opt to apply the terms of the ordinary GNU General Public
567License instead of this License to a given copy of the Library.  To do
568this, you must alter all the notices that refer to this License, so
569that they refer to the ordinary GNU General Public License, version 2,
570instead of to this License.  (If a newer version than version 2 of the
571ordinary GNU General Public License has appeared, then you can specify
572that version instead if you wish.)  Do not make any other change in
573these notices.
574
575  Once this change is made in a given copy, it is irreversible for
576that copy, so the ordinary GNU General Public License applies to all
577subsequent copies and derivative works made from that copy.
578
579  This option is useful when you wish to copy part of the code of
580the Library into a program that is not a library.
581
582  4. You may copy and distribute the Library (or a portion or
583derivative of it, under Section 2) in object code or executable form
584under the terms of Sections 1 and 2 above provided that you accompany
585it with the complete corresponding machine-readable source code, which
586must be distributed under the terms of Sections 1 and 2 above on a
587medium customarily used for software interchange.
588
589  If distribution of object code is made by offering access to copy
590from a designated place, then offering equivalent access to copy the
591source code from the same place satisfies the requirement to
592distribute the source code, even though third parties are not
593compelled to copy the source along with the object code.
594
595  5. A program that contains no derivative of any portion of the
596Library, but is designed to work with the Library by being compiled or
597linked with it, is called a "work that uses the Library".  Such a
598work, in isolation, is not a derivative work of the Library, and
599therefore falls outside the scope of this License.
600
601  However, linking a "work that uses the Library" with the Library
602creates an executable that is a derivative of the Library (because it
603contains portions of the Library), rather than a "work that uses the
604library".  The executable is therefore covered by this License.
605Section 6 states terms for distribution of such executables.
606
607  When a "work that uses the Library" uses material from a header file
608that is part of the Library, the object code for the work may be a
609derivative work of the Library even though the source code is not.
610Whether this is true is especially significant if the work can be
611linked without the Library, or if the work is itself a library.  The
612threshold for this to be true is not precisely defined by law.
613
614  If such an object file uses only numerical parameters, data
615structure layouts and accessors, and small macros and small inline
616functions (ten lines or less in length), then the use of the object
617file is unrestricted, regardless of whether it is legally a derivative
618work.  (Executables containing this object code plus portions of the
619Library will still fall under Section 6.)
620
621  Otherwise, if the work is a derivative of the Library, you may
622distribute the object code for the work under the terms of Section 6.
623Any executables containing that work also fall under Section 6,
624whether or not they are linked directly with the Library itself.
625
626  6. As an exception to the Sections above, you may also compile or
627link a "work that uses the Library" with the Library to produce a
628work containing portions of the Library, and distribute that work
629under terms of your choice, provided that the terms permit
630modification of the work for the customer's own use and reverse
631engineering for debugging such modifications.
632
633  You must give prominent notice with each copy of the work that the
634Library is used in it and that the Library and its use are covered by
635this License.  You must supply a copy of this License.  If the work
636during execution displays copyright notices, you must include the
637copyright notice for the Library among them, as well as a reference
638directing the user to the copy of this License.  Also, you must do one
639of these things:
640
641    a) Accompany the work with the complete corresponding
642    machine-readable source code for the Library including whatever
643    changes were used in the work (which must be distributed under
644    Sections 1 and 2 above); and, if the work is an executable linked
645    with the Library, with the complete machine-readable "work that
646    uses the Library", as object code and/or source code, so that the
647    user can modify the Library and then relink to produce a modified
648    executable containing the modified Library.  (It is understood
649    that the user who changes the contents of definitions files in the
650    Library will not necessarily be able to recompile the application
651    to use the modified definitions.)
652
653    b) 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    c) 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    d) 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 source code distributed need not include anything that is normally
669distributed (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 to
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 Library 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 Library General Public
825    License as published by the Free Software Foundation; either
826    version 2 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    Library General Public License for more details.
832
833    You should have received a copy of the GNU Library 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
