   257 		  GNU LIBRARY GENERAL PUBLIC LICENSE

   258 		       Version 2, June 1991

   259 

   260  Copyright (C) 1991 Free Software Foundation, Inc.

   261  Everyone is permitted to copy and distribute verbatim copies

   262  of this license document, but changing it is not allowed.

   263 

   264 [This is the first released version of the library GPL.  It is

   265  numbered 2 because it goes with version 2 of the ordinary GPL.]

   266 

   267 			    Preamble

   268 

   269   The licenses for most software are designed to take away your

   270 freedom to share and change it.  By contrast, the GNU General Public

   271 Licenses are intended to guarantee your freedom to share and change

   272 free software--to make sure the software is free for all its users.

   273 

   274   This license, the Library General Public License, applies to some

   275 specially designated Free Software Foundation software, and to any

   276 other libraries whose authors decide to use it.  You can use it for

   277 your libraries, too.

   278 

   279   When we speak of free software, we are referring to freedom, not

   280 price.  Our General Public Licenses are designed to make sure that you

   281 have the freedom to distribute copies of free software (and charge for

   282 this service if you wish), that you receive source code or can get it

   283 if you want it, that you can change the software or use pieces of it

   284 in new free programs; and that you know you can do these things.

   285 

   286   To protect your rights, we need to make restrictions that forbid

   287 anyone to deny you these rights or to ask you to surrender the rights.

   288 These restrictions translate to certain responsibilities for you if

   289 you distribute copies of the library, or if you modify it.

   290 

   291   For example, if you distribute copies of the library, whether gratis

   292 or for a fee, you must give the recipients all the rights that we gave

   293 you.  You must make sure that they, too, receive or can get the source

   294 code.  If you link a program with the library, you must provide

   295 complete object files to the recipients so that they can relink them

   296 with the library, after making changes to the library and recompiling

   297 it.  And you must show them these terms so they know their rights.

   298 

   299   Our method of protecting your rights has two steps: (1) copyright

   300 the library, and (2) offer you this license which gives you legal

   301 permission to copy, distribute and/or modify the library.

   302 

   303   Also, for each distributor's protection, we want to make certain

   304 that everyone understands that there is no warranty for this free

   305 library.  If the library is modified by someone else and passed on, we

   306 want its recipients to know that what they have is not the original

   307 version, so that any problems introduced by others will not reflect on

   308 the original authors' reputations.

   309 

   310 

   311   Finally, any free program is threatened constantly by software

   312 patents.  We wish to avoid the danger that companies distributing free

   313 software will individually obtain patent licenses, thus in effect

   314 transforming the program into proprietary software.  To prevent this,

   315 we have made it clear that any patent must be licensed for everyone's

   316 free use or not licensed at all.

   317 

   318   Most GNU software, including some libraries, is covered by the ordinary

   319 GNU General Public License, which was designed for utility programs.  This

   320 license, the GNU Library General Public License, applies to certain

   321 designated libraries.  This license is quite different from the ordinary

   322 one; be sure to read it in full, and don't assume that anything in it is

   323 the same as in the ordinary license.

   324 

   325   The reason we have a separate public license for some libraries is that

   326 they blur the distinction we usually make between modifying or adding to a

   327 program and simply using it.  Linking a program with a library, without

   328 changing the library, is in some sense simply using the library, and is

   329 analogous to running a utility program or application program.  However, in

   330 a textual and legal sense, the linked executable is a combined work, a

   331 derivative of the original library, and the ordinary General Public License

   332 treats it as such.

   333 

   334   Because of this blurred distinction, using the ordinary General

   335 Public License for libraries did not effectively promote software

   336 sharing, because most developers did not use the libraries.  We

   337 concluded that weaker conditions might promote sharing better.

   338 

   339   However, unrestricted linking of non-free programs would deprive the

   340 users of those programs of all benefit from the free status of the

   341 libraries themselves.  This Library General Public License is intended to

   342 permit developers of non-free programs to use free libraries, while

   343 preserving your freedom as a user of such programs to change the free

   344 libraries that are incorporated in them.  (We have not seen how to achieve

   345 this as regards changes in header files, but we have achieved it as regards

   346 changes in the actual functions of the Library.)  The hope is that this

   347 will lead to faster development of free libraries.

   348 

   349   The precise terms and conditions for copying, distribution and

   350 modification follow.  Pay close attention to the difference between a

   351 "work based on the library" and a "work that uses the library".  The

   352 former contains code derived from the library, while the latter only

   353 works together with the library.

   354 

   355   Note that it is possible for a library to be covered by the ordinary

   356 General Public License rather than by this special one.

   357 

   358 

   359 		  GNU LIBRARY GENERAL PUBLIC LICENSE

   360    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

   361 

   362   0. This License Agreement applies to any software library which

   363 contains a notice placed by the copyright holder or other authorized

   364 party saying it may be distributed under the terms of this Library

   365 General Public License (also called "this License").  Each licensee is

   366 addressed as "you".

   367 

   368   A "library" means a collection of software functions and/or data

   369 prepared so as to be conveniently linked with application programs

   370 (which use some of those functions and data) to form executables.

   371 

   372   The "Library", below, refers to any such software library or work

   373 which has been distributed under these terms.  A "work based on the

   374 Library" means either the Library or any derivative work under

   375 copyright law: that is to say, a work containing the Library or a

   376 portion of it, either verbatim or with modifications and/or translated

   377 straightforwardly into another language.  (Hereinafter, translation is

   378 included without limitation in the term "modification".)

   379 

   380   "Source code" for a work means the preferred form of the work for

   381 making modifications to it.  For a library, complete source code means

   382 all the source code for all modules it contains, plus any associated

   383 interface definition files, plus the scripts used to control compilation

   384 and installation of the library.

   385 

   386   Activities other than copying, distribution and modification are not

   387 covered by this License; they are outside its scope.  The act of

   388 running a program using the Library is not restricted, and output from

   389 such a program is covered only if its contents constitute a work based

   390 on the Library (independent of the use of the Library in a tool for

   391 writing it).  Whether that is true depends on what the Library does

   392 and what the program that uses the Library does.

   393   

   394   1. You may copy and distribute verbatim copies of the Library's

   395 complete source code as you receive it, in any medium, provided that

   396 you conspicuously and appropriately publish on each copy an

   397 appropriate copyright notice and disclaimer of warranty; keep intact

   398 all the notices that refer to this License and to the absence of any

   399 warranty; and distribute a copy of this License along with the

   400 Library.

   401 

   402   You may charge a fee for the physical act of transferring a copy,

   403 and you may at your option offer warranty protection in exchange for a

   404 fee.

   405 

   406 

   407   2. You may modify your copy or copies of the Library or any portion

   408 of it, thus forming a work based on the Library, and copy and

   409 distribute such modifications or work under the terms of Section 1

   410 above, provided that you also meet all of these conditions:

   411 

   412     a) The modified work must itself be a software library.

   413 

   414     b) You must cause the files modified to carry prominent notices

   415     stating that you changed the files and the date of any change.

   416 

   417     c) You must cause the whole of the work to be licensed at no

   418     charge to all third parties under the terms of this License.

   419 

   420     d) If a facility in the modified Library refers to a function or a

   421     table of data to be supplied by an application program that uses

   422     the facility, other than as an argument passed when the facility

   423     is invoked, then you must make a good faith effort to ensure that,

   424     in the event an application does not supply such function or

   425     table, the facility still operates, and performs whatever part of

   426     its purpose remains meaningful.

   427 

   428     (For example, a function in a library to compute square roots has

   429     a purpose that is entirely well-defined independent of the

   430     application.  Therefore, Subsection 2d requires that any

   431     application-supplied function or table used by this function must

   432     be optional: if the application does not supply it, the square

   433     root function must still compute square roots.)

   434 

   435 These requirements apply to the modified work as a whole.  If

   436 identifiable sections of that work are not derived from the Library,

   437 and can be reasonably considered independent and separate works in

   438 themselves, then this License, and its terms, do not apply to those

   439 sections when you distribute them as separate works.  But when you

   440 distribute the same sections as part of a whole which is a work based

   441 on the Library, the distribution of the whole must be on the terms of

   442 this License, whose permissions for other licensees extend to the

   443 entire whole, and thus to each and every part regardless of who wrote

   444 it.

   445 

   446 Thus, it is not the intent of this section to claim rights or contest

   447 your rights to work written entirely by you; rather, the intent is to

   448 exercise the right to control the distribution of derivative or

   449 collective works based on the Library.

   450 

   451 In addition, mere aggregation of another work not based on the Library

   452 with the Library (or with a work based on the Library) on a volume of

   453 a storage or distribution medium does not bring the other work under

   454 the scope of this License.

   455 

   456   3. You may opt to apply the terms of the ordinary GNU General Public

   457 License instead of this License to a given copy of the Library.  To do

   458 this, you must alter all the notices that refer to this License, so

   459 that they refer to the ordinary GNU General Public License, version 2,

   460 instead of to this License.  (If a newer version than version 2 of the

   461 ordinary GNU General Public License has appeared, then you can specify

   462 that version instead if you wish.)  Do not make any other change in

   463 these notices.

   464 

   465 

   466   Once this change is made in a given copy, it is irreversible for

   467 that copy, so the ordinary GNU General Public License applies to all

   468 subsequent copies and derivative works made from that copy.

   469 

   470   This option is useful when you wish to copy part of the code of

   471 the Library into a program that is not a library.

   472 

   473   4. You may copy and distribute the Library (or a portion or

   474 derivative of it, under Section 2) in object code or executable form

   475 under the terms of Sections 1 and 2 above provided that you accompany

   476 it with the complete corresponding machine-readable source code, which

   477 must be distributed under the terms of Sections 1 and 2 above on a

   478 medium customarily used for software interchange.

   479 

   480   If distribution of object code is made by offering access to copy

   481 from a designated place, then offering equivalent access to copy the

   482 source code from the same place satisfies the requirement to

   483 distribute the source code, even though third parties are not

   484 compelled to copy the source along with the object code.

   485 

   486   5. A program that contains no derivative of any portion of the

   487 Library, but is designed to work with the Library by being compiled or

   488 linked with it, is called a "work that uses the Library".  Such a

   489 work, in isolation, is not a derivative work of the Library, and

   490 therefore falls outside the scope of this License.

   491 

   492   However, linking a "work that uses the Library" with the Library

   493 creates an executable that is a derivative of the Library (because it

   494 contains portions of the Library), rather than a "work that uses the

   495 library".  The executable is therefore covered by this License.

   496 Section 6 states terms for distribution of such executables.

   497 

   498   When a "work that uses the Library" uses material from a header file

   499 that is part of the Library, the object code for the work may be a

   500 derivative work of the Library even though the source code is not.

   501 Whether this is true is especially significant if the work can be

   502 linked without the Library, or if the work is itself a library.  The

   503 threshold for this to be true is not precisely defined by law.

   504 

   505   If such an object file uses only numerical parameters, data

   506 structure layouts and accessors, and small macros and small inline

   507 functions (ten lines or less in length), then the use of the object

   508 file is unrestricted, regardless of whether it is legally a derivative

   509 work.  (Executables containing this object code plus portions of the

   510 Library will still fall under Section 6.)

   511 

   512   Otherwise, if the work is a derivative of the Library, you may

   513 distribute the object code for the work under the terms of Section 6.

   514 Any executables containing that work also fall under Section 6,

   515 whether or not they are linked directly with the Library itself.

   516 

   517 

   518   6. As an exception to the Sections above, you may also compile or

   519 link a "work that uses the Library" with the Library to produce a

   520 work containing portions of the Library, and distribute that work

   521 under terms of your choice, provided that the terms permit

   522 modification of the work for the customer's own use and reverse

   523 engineering for debugging such modifications.

   524 

   525   You must give prominent notice with each copy of the work that the

   526 Library is used in it and that the Library and its use are covered by

   527 this License.  You must supply a copy of this License.  If the work

   528 during execution displays copyright notices, you must include the

   529 copyright notice for the Library among them, as well as a reference

   530 directing the user to the copy of this License.  Also, you must do one

   531 of these things:

   532 

   533     a) Accompany the work with the complete corresponding

   534     machine-readable source code for the Library including whatever

   535     changes were used in the work (which must be distributed under

   536     Sections 1 and 2 above); and, if the work is an executable linked

   537     with the Library, with the complete machine-readable "work that

   538     uses the Library", as object code and/or source code, so that the

   539     user can modify the Library and then relink to produce a modified

   540     executable containing the modified Library.  (It is understood

   541     that the user who changes the contents of definitions files in the

   542     Library will not necessarily be able to recompile the application

   543     to use the modified definitions.)

   544 

   545     b) Accompany the work with a written offer, valid for at

   546     least three years, to give the same user the materials

   547     specified in Subsection 6a, above, for a charge no more

   548     than the cost of performing this distribution.

   549 

   550     c) If distribution of the work is made by offering access to copy

   551     from a designated place, offer equivalent access to copy the above

   552     specified materials from the same place.

   553 

   554     d) Verify that the user has already received a copy of these

   555     materials or that you have already sent this user a copy.

   556 

   557   For an executable, the required form of the "work that uses the

   558 Library" must include any data and utility programs needed for

   559 reproducing the executable from it.  However, as a special exception,

   560 the source code distributed need not include anything that is normally

   561 distributed (in either source or binary form) with the major

   562 components (compiler, kernel, and so on) of the operating system on

   563 which the executable runs, unless that component itself accompanies

   564 the executable.

   565 

   566   It may happen that this requirement contradicts the license

   567 restrictions of other proprietary libraries that do not normally

   568 accompany the operating system.  Such a contradiction means you cannot

   569 use both them and the Library together in an executable that you

   570 distribute.

   571 

   572 

   573   7. You may place library facilities that are a work based on the

   574 Library side-by-side in a single library together with other library

   575 facilities not covered by this License, and distribute such a combined

   576 library, provided that the separate distribution of the work based on

   577 the Library and of the other library facilities is otherwise

   578 permitted, and provided that you do these two things:

   579 

   580     a) Accompany the combined library with a copy of the same work

   581     based on the Library, uncombined with any other library

   582     facilities.  This must be distributed under the terms of the

   583     Sections above.

   584 

   585     b) Give prominent notice with the combined library of the fact

   586     that part of it is a work based on the Library, and explaining

   587     where to find the accompanying uncombined form of the same work.

   588 

   589   8. You may not copy, modify, sublicense, link with, or distribute

   590 the Library except as expressly provided under this License.  Any

   591 attempt otherwise to copy, modify, sublicense, link with, or

   592 distribute the Library is void, and will automatically terminate your

   593 rights under this License.  However, parties who have received copies,

   594 or rights, from you under this License will not have their licenses

   595 terminated so long as such parties remain in full compliance.

   596 

   597   9. You are not required to accept this License, since you have not

   598 signed it.  However, nothing else grants you permission to modify or

   599 distribute the Library or its derivative works.  These actions are

   600 prohibited by law if you do not accept this License.  Therefore, by

   601 modifying or distributing the Library (or any work based on the

   602 Library), you indicate your acceptance of this License to do so, and

   603 all its terms and conditions for copying, distributing or modifying

   604 the Library or works based on it.

   605 

   606   10. Each time you redistribute the Library (or any work based on the

   607 Library), the recipient automatically receives a license from the

   608 original licensor to copy, distribute, link with or modify the Library

   609 subject to these terms and conditions.  You may not impose any further

   610 restrictions on the recipients' exercise of the rights granted herein.

   611 You are not responsible for enforcing compliance by third parties to

   612 this License.

   613 

   614 

   615   11. If, as a consequence of a court judgment or allegation of patent

   616 infringement or for any other reason (not limited to patent issues),

   617 conditions are imposed on you (whether by court order, agreement or

   618 otherwise) that contradict the conditions of this License, they do not

   619 excuse you from the conditions of this License.  If you cannot

   620 distribute so as to satisfy simultaneously your obligations under this

   621 License and any other pertinent obligations, then as a consequence you

   622 may not distribute the Library at all.  For example, if a patent

   623 license would not permit royalty-free redistribution of the Library by

   624 all those who receive copies directly or indirectly through you, then

   625 the only way you could satisfy both it and this License would be to

   626 refrain entirely from distribution of the Library.

   627 

   628 If any portion of this section is held invalid or unenforceable under any

   629 particular circumstance, the balance of the section is intended to apply,

   630 and the section as a whole is intended to apply in other circumstances.

   631 

   632 It is not the purpose of this section to induce you to infringe any

   633 patents or other property right claims or to contest validity of any

   634 such claims; this section has the sole purpose of protecting the

   635 integrity of the free software distribution system which is

   636 implemented by public license practices.  Many people have made

   637 generous contributions to the wide range of software distributed

   638 through that system in reliance on consistent application of that

   639 system; it is up to the author/donor to decide if he or she is willing

   640 to distribute software through any other system and a licensee cannot

   641 impose that choice.

   642 

   643 This section is intended to make thoroughly clear what is believed to

   644 be a consequence of the rest of this License.

   645 

   646   12. If the distribution and/or use of the Library is restricted in

   647 certain countries either by patents or by copyrighted interfaces, the

   648 original copyright holder who places the Library under this License may add

   649 an explicit geographical distribution limitation excluding those countries,

   650 so that distribution is permitted only in or among countries not thus

   651 excluded.  In such case, this License incorporates the limitation as if

   652 written in the body of this License.

   653 

   654   13. The Free Software Foundation may publish revised and/or new

   655 versions of the Library General Public License from time to time.

   656 Such new versions will be similar in spirit to the present version,

   657 but may differ in detail to address new problems or concerns.

   658 

   659 Each version is given a distinguishing version number.  If the Library

   660 specifies a version number of this License which applies to it and

   661 "any later version", you have the option of following the terms and

   662 conditions either of that version or of any later version published by

   663 the Free Software Foundation.  If the Library does not specify a

   664 license version number, you may choose any version ever published by

   665 the Free Software Foundation.

   666 

   667 

   668   14. If you wish to incorporate parts of the Library into other free

   669 programs whose distribution conditions are incompatible with these,

   670 write to the author to ask for permission.  For software which is

   671 copyrighted by the Free Software Foundation, write to the Free

   672 Software Foundation; we sometimes make exceptions for this.  Our

   673 decision will be guided by the two goals of preserving the free status

   674 of all derivatives of our free software and of promoting the sharing

   675 and reuse of software generally.

   676 

   677 			    NO WARRANTY

   678 

   679   15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO

   680 WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.

   681 EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR

   682 OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY

   687 THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

   688 

   689   16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN

   697 SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH

   698 DAMAGES.

   703      Appendix: How to Apply These Terms to Your New Libraries

   704 

   705   If you develop a new library, and you want it to be of the greatest

   706 possible use to the public, we recommend making it free software that

   707 everyone can redistribute and change.  You can do so by permitting

   708 redistribution under these terms (or, alternatively, under the terms of the

   709 ordinary General Public License).

   710 

   711   To apply these terms, attach the following notices to the library.  It is

   712 safest to attach them to the start of each source file to most effectively

   713 convey the exclusion of warranty; and each file should have at least the

   714 "copyright" line and a pointer to where the full notice is found.

   715 

   716     <one line to give the library's name and a brief idea of what it does.>

   717     Copyright (C) <year>  <name of author>

   718 

   719     This library is free software; you can redistribute it and/or

   720     modify it under the terms of the GNU Library General Public

   721     License as published by the Free Software Foundation; either

   722     version 2 of the License, or (at your option) any later version.

   723 

   724     This library is distributed in the hope that it will be useful,

   725     but WITHOUT ANY WARRANTY; without even the implied warranty of

   726     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU

   727     Library General Public License for more details.

   728 

   729     You should have received a copy of the GNU Library General Public

   730     License along with this library; if not, write to the Free

   731     Software Foundation, Inc.

   732 

   733 Also add information on how to contact you by electronic and paper mail.

   734 

   735 You should also get your employer (if you work as a programmer) or your

   736 school, if any, to sign a "copyright disclaimer" for the library, if

   737 necessary.  Here is a sample; alter the names:

   738

   747                     GNU GENERAL PUBLIC LICENSE

   748                        Version 2, June 1991

   749 

   750  Copyright (C) 1989, 1991 Free Software Foundation, Inc.,

   751  51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA

   752  Everyone is permitted to copy and distribute verbatim copies

   753  of this license document, but changing it is not allowed.

   754 

   755                             Preamble

   756 

   757   The licenses for most software are designed to take away your

   758 freedom to share and change it.  By contrast, the GNU General Public

   759 License is intended to guarantee your freedom to share and change free

   760 software--to make sure the software is free for all its users.  This

   761 General Public License applies to most of the Free Software

   762 Foundation's software and to any other program whose authors commit to

   763 using it.  (Some other Free Software Foundation software is covered by

   764 the GNU Lesser General Public License instead.)  You can apply it to

   765 your programs, too.

   766 

   767   When we speak of free software, we are referring to freedom, not

   768 price.  Our General Public Licenses are designed to make sure that you

   769 have the freedom to distribute copies of free software (and charge for

   770 this service if you wish), that you receive source code or can get it

   771 if you want it, that you can change the software or use pieces of it

   772 in new free programs; and that you know you can do these things.

   773 

   774   To protect your rights, we need to make restrictions that forbid

   775 anyone to deny you these rights or to ask you to surrender the rights.

   776 These restrictions translate to certain responsibilities for you if you

   777 distribute copies of the software, or if you modify it.

   778 

   779   For example, if you distribute copies of such a program, whether

   780 gratis or for a fee, you must give the recipients all the rights that

   781 you have.  You must make sure that they, too, receive or can get the

   782 source code.  And you must show them these terms so they know their

   783 rights.

   784 

   785   We protect your rights with two steps: (1) copyright the software, and

   786 (2) offer you this license which gives you legal permission to copy,

   787 distribute and/or modify the software.

   788 

   789   Also, for each author's protection and ours, we want to make certain

   790 that everyone understands that there is no warranty for this free

   791 software.  If the software is modified by someone else and passed on, we

   792 want its recipients to know that what they have is not the original, so

   793 that any problems introduced by others will not reflect on the original

   794 authors' reputations.

   795 

   796   Finally, any free program is threatened constantly by software

   797 patents.  We wish to avoid the danger that redistributors of a free

   798 program will individually obtain patent licenses, in effect making the

   799 program proprietary.  To prevent this, we have made it clear that any

   800 patent must be licensed for everyone's free use or not licensed at all.

   801 

   802   The precise terms and conditions for copying, distribution and

   803 modification follow.

   804 

   805                     GNU GENERAL PUBLIC LICENSE

   806    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

   807 

   808   0. This License applies to any program or other work which contains

   809 a notice placed by the copyright holder saying it may be distributed

   810 under the terms of this General Public License.  The "Program", below,

   811 refers to any such program or work, and a "work based on the Program"

   812 means either the Program or any derivative work under copyright law:

   813 that is to say, a work containing the Program or a portion of it,

   814 either verbatim or with modifications and/or translated into another

   815 language.  (Hereinafter, translation is included without limitation in

   816 the term "modification".)  Each licensee is addressed as "you".

   817 

   818 Activities other than copying, distribution and modification are not

   819 covered by this License; they are outside its scope.  The act of

   820 running the Program is not restricted, and the output from the Program

   821 is covered only if its contents constitute a work based on the

   822 Program (independent of having been made by running the Program).

   823 Whether that is true depends on what the Program does.

   824 

   825   1. You may copy and distribute verbatim copies of the Program's

   826 source code as you receive it, in any medium, provided that you

   827 conspicuously and appropriately publish on each copy an appropriate

   828 copyright notice and disclaimer of warranty; keep intact all the

   829 notices that refer to this License and to the absence of any warranty;

   830 and give any other recipients of the Program a copy of this License

   831 along with the Program.

   832 

   833 You may charge a fee for the physical act of transferring a copy, and

   834 you may at your option offer warranty protection in exchange for a fee.

   835 

   836   2. You may modify your copy or copies of the Program or any portion

   837 of it, thus forming a work based on the Program, and copy and

   838 distribute such modifications or work under the terms of Section 1

   839 above, provided that you also meet all of these conditions:

   840 

   841     a) You must cause the modified files to carry prominent notices

   842     stating that you changed the files and the date of any change.

   843 

   844     b) You must cause any work that you distribute or publish, that in

   845     whole or in part contains or is derived from the Program or any

   846     part thereof, to be licensed as a whole at no charge to all third

   847     parties under the terms of this License.

   848 

   849     c) If the modified program normally reads commands interactively

   850     when run, you must cause it, when started running for such

   851     interactive use in the most ordinary way, to print or display an

   852     announcement including an appropriate copyright notice and a

   853     notice that there is no warranty (or else, saying that you provide

   854     a warranty) and that users may redistribute the program under

   855     these conditions, and telling the user how to view a copy of this

   856     License.  (Exception: if the Program itself is interactive but

   857     does not normally print such an announcement, your work based on

   858     the Program is not required to print an announcement.)

   859 

   860 These requirements apply to the modified work as a whole.  If

   861 identifiable sections of that work are not derived from the Program,

   862 and can be reasonably considered independent and separate works in

   863 themselves, then this License, and its terms, do not apply to those

   864 sections when you distribute them as separate works.  But when you

   865 distribute the same sections as part of a whole which is a work based

   866 on the Program, the distribution of the whole must be on the terms of

   867 this License, whose permissions for other licensees extend to the

   868 entire whole, and thus to each and every part regardless of who wrote it.

   869 

   870 Thus, it is not the intent of this section to claim rights or contest

   871 your rights to work written entirely by you; rather, the intent is to

   872 exercise the right to control the distribution of derivative or

   873 collective works based on the Program.

   874 

   875 In addition, mere aggregation of another work not based on the Program

   876 with the Program (or with a work based on the Program) on a volume of

   877 a storage or distribution medium does not bring the other work under

   878 the scope of this License.

   879 

   880   3. You may copy and distribute the Program (or a work based on it,

   881 under Section 2) in object code or executable form under the terms of

   882 Sections 1 and 2 above provided that you also do one of the following:

   883 

   884     a) Accompany it with the complete corresponding machine-readable

   885     source code, which must be distributed under the terms of Sections

   886     1 and 2 above on a medium customarily used for software interchange; or,

   887 

   888     b) Accompany it with a written offer, valid for at least three

   889     years, to give any third party, for a charge no more than your

   890     cost of physically performing source distribution, a complete

   891     machine-readable copy of the corresponding source code, to be

   892     distributed under the terms of Sections 1 and 2 above on a medium

   893     customarily used for software interchange; or,

   894 

   895     c) Accompany it with the information you received as to the offer

   896     to distribute corresponding source code.  (This alternative is

   897     allowed only for noncommercial distribution and only if you

   898     received the program in object code or executable form with such

   899     an offer, in accord with Subsection b above.)

   900 

   901 The source code for a work means the preferred form of the work for

   902 making modifications to it.  For an executable work, complete source

   903 code means all the source code for all modules it contains, plus any

   904 associated interface definition files, plus the scripts used to

   905 control compilation and installation of the executable.  However, as a

   906 special exception, the source code distributed need not include

   907 anything that is normally distributed (in either source or binary

   908 form) with the major components (compiler, kernel, and so on) of the

   909 operating system on which the executable runs, unless that component

   910 itself accompanies the executable.

   911 

   912 If distribution of executable or object code is made by offering

   913 access to copy from a designated place, then offering equivalent

   914 access to copy the source code from the same place counts as

   915 distribution of the source code, even though third parties are not

   916 compelled to copy the source along with the object code.

   917 

   918   4. You may not copy, modify, sublicense, or distribute the Program

   919 except as expressly provided under this License.  Any attempt

   920 otherwise to copy, modify, sublicense or distribute the Program is

   921 void, and will automatically terminate your rights under this License.

   922 However, parties who have received copies, or rights, from you under

   923 this License will not have their licenses terminated so long as such

   924 parties remain in full compliance.

   925 

   926   5. You are not required to accept this License, since you have not

   927 signed it.  However, nothing else grants you permission to modify or

   928 distribute the Program or its derivative works.  These actions are

   929 prohibited by law if you do not accept this License.  Therefore, by

   930 modifying or distributing the Program (or any work based on the

   931 Program), you indicate your acceptance of this License to do so, and

   932 all its terms and conditions for copying, distributing or modifying

   933 the Program or works based on it.

   934 

   935   6. Each time you redistribute the Program (or any work based on the

   936 Program), the recipient automatically receives a license from the

   937 original licensor to copy, distribute or modify the Program subject to

   938 these terms and conditions.  You may not impose any further

   939 restrictions on the recipients' exercise of the rights granted herein.

   940 You are not responsible for enforcing compliance by third parties to

   941 this License.

   942 

   943   7. If, as a consequence of a court judgment or allegation of patent

   944 infringement or for any other reason (not limited to patent issues),

   945 conditions are imposed on you (whether by court order, agreement or

   946 otherwise) that contradict the conditions of this License, they do not

   947 excuse you from the conditions of this License.  If you cannot

   948 distribute so as to satisfy simultaneously your obligations under this

   949 License and any other pertinent obligations, then as a consequence you

   950 may not distribute the Program at all.  For example, if a patent

   951 license would not permit royalty-free redistribution of the Program by

   952 all those who receive copies directly or indirectly through you, then

   953 the only way you could satisfy both it and this License would be to

   954 refrain entirely from distribution of the Program.

   955 

   956 If any portion of this section is held invalid or unenforceable under

   957 any particular circumstance, the balance of the section is intended to

   958 apply and the section as a whole is intended to apply in other

   959 circumstances.

   960 

   961 It is not the purpose of this section to induce you to infringe any

   962 patents or other property right claims or to contest validity of any

   963 such claims; this section has the sole purpose of protecting the

   964 integrity of the free software distribution system, which is

   965 implemented by public license practices.  Many people have made

   966 generous contributions to the wide range of software distributed

   967 through that system in reliance on consistent application of that

   968 system; it is up to the author/donor to decide if he or she is willing

   969 to distribute software through any other system and a licensee cannot

   970 impose that choice.

   971 

   972 This section is intended to make thoroughly clear what is believed to

   973 be a consequence of the rest of this License.

   974 

   975   8. If the distribution and/or use of the Program is restricted in

   976 certain countries either by patents or by copyrighted interfaces, the

   977 original copyright holder who places the Program under this License

   978 may add an explicit geographical distribution limitation excluding

   979 those countries, so that distribution is permitted only in or among

   980 countries not thus excluded.  In such case, this License incorporates

   981 the limitation as if written in the body of this License.

   982 

   983   9. The Free Software Foundation may publish revised and/or new versions

   984 of the General Public License from time to time.  Such new versions will

   985 be similar in spirit to the present version, but may differ in detail to

   986 address new problems or concerns.

   987 

   988 Each version is given a distinguishing version number.  If the Program

   989 specifies a version number of this License which applies to it and "any

   990 later version", you have the option of following the terms and conditions

   991 either of that version or of any later version published by the Free

   992 Software Foundation.  If the Program does not specify a version number of

   993 this License, you may choose any version ever published by the Free Software

   994 Foundation.

   995 

   996   10. If you wish to incorporate parts of the Program into other free

   997 programs whose distribution conditions are different, write to the author

   998 to ask for permission.  For software which is copyrighted by the Free

   999 Software Foundation, write to the Free Software Foundation; we sometimes

  1000 make exceptions for this.  Our decision will be guided by the two goals

  1001 of preserving the free status of all derivatives of our free software and

  1002 of promoting the sharing and reuse of software generally.

  1003 

  1004                             NO WARRANTY

  1005 

  1006   11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY

  1007 FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN

  1008 OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES

  1009 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED

  1010 OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF

  1011 MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS

  1012 TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE

  1013 PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,

  1014 REPAIR OR CORRECTION.

  1015 

  1016   12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

  1017 WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR

  1018 REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,

  1019 INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING

  1020 OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED

  1021 TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY

  1022 YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER

  1023 PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE

  1024 POSSIBILITY OF SUCH DAMAGES.

  1025 

  1026                      END OF TERMS AND CONDITIONS

  1027 

  1028             How to Apply These Terms to Your New Programs

  1029 

  1030   If you develop a new program, and you want it to be of the greatest

  1031 possible use to the public, the best way to achieve this is to make it

  1032 free software which everyone can redistribute and change under these terms.

  1033 

  1034   To do so, attach the following notices to the program.  It is safest

  1035 to attach them to the start of each source file to most effectively

  1036 convey the exclusion of warranty; and each file should have at least

  1037 the "copyright" line and a pointer to where the full notice is found.

  1038 

  1039     <one line to give the program's name and a brief idea of what it does.>

  1040     Copyright (C) <year>  <name of author>

  1041 

  1042     This program is free software; you can redistribute it and/or modify

  1043     it under the terms of the GNU General Public License as published by

  1044     the Free Software Foundation; either version 2 of the License, or

  1045     (at your option) any later version.

  1046 

  1047     This program is distributed in the hope that it will be useful,

  1048     but WITHOUT ANY WARRANTY; without even the implied warranty of

  1049     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

  1050     GNU General Public License for more details.

  1051 

  1052     You should have received a copy of the GNU General Public License along

  1053     with this program; if not, write to the Free Software Foundation, Inc.,

  1054     51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.

  1055 

  1056 Also add information on how to contact you by electronic and paper mail.

  1057 

  1058 If the program is interactive, make it output a short notice like this

  1059 when it starts in an interactive mode:

  1060 

  1061     Gnomovision version 69, Copyright (C) year name of author

  1062     Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

  1063     This is free software, and you are welcome to redistribute it

  1064     under certain conditions; type `show c' for details.

  1065 

  1066 The hypothetical commands `show w' and `show c' should show the appropriate

  1067 parts of the General Public License.  Of course, the commands you use may

  1068 be called something other than `show w' and `show c'; they could even be

  1069 mouse-clicks or menu items--whatever suits your program.

  1070 

  1071 You should also get your employer (if you work as a programmer) or your

  1072 school, if any, to sign a "copyright disclaimer" for the program, if

  1073 necessary.  Here is a sample; alter the names:

  1074 

  1075   Yoyodyne, Inc., hereby disclaims all copyright interest in the program

  1076   `Gnomovision' (which makes passes at compilers) written by James Hacker.

  1080 

  1081 This General Public License does not permit incorporating your program into

  1082 proprietary programs.  If your program is a subroutine library, you may

  1083 consider it more useful to permit linking proprietary applications with the

  1084 library.  If this is what you want to do, use the GNU Lesser General

  1085 Public License instead of this License.

  1097 

  1098 [This is the first released version of the library GPL.  It is

  1099  numbered 2 because it goes with version 2 of the ordinary GPL.]

  1100 

  1101                             Preamble

  1102 

  1103   The licenses for most software are designed to take away your

  1104 freedom to share and change it.  By contrast, the GNU General Public

  1105 Licenses are intended to guarantee your freedom to share and change

  1106 free software--to make sure the software is free for all its users.

  1107 

  1108   This license, the Library General Public License, applies to some

  1109 specially designated Free Software Foundation software, and to any

  1110 other libraries whose authors decide to use it.  You can use it for

  1111 your libraries, too.

  1112 

  1113   When we speak of free software, we are referring to freedom, not

  1114 price.  Our General Public Licenses are designed to make sure that you

  1115 have the freedom to distribute copies of free software (and charge for

  1116 this service if you wish), that you receive source code or can get it

  1117 if you want it, that you can change the software or use pieces of it

  1118 in new free programs; and that you know you can do these things.

  1119 

  1120   To protect your rights, we need to make restrictions that forbid

  1121 anyone to deny you these rights or to ask you to surrender the rights.

  1122 These restrictions translate to certain responsibilities for you if

  1123 you distribute copies of the library, or if you modify it.

  1124 

  1125   For example, if you distribute copies of the library, whether gratis

  1126 or for a fee, you must give the recipients all the rights that we gave

  1127 you.  You must make sure that they, too, receive or can get the source

  1128 code.  If you link a program with the library, you must provide

  1129 complete object files to the recipients so that they can relink them

  1130 with the library, after making changes to the library and recompiling

  1131 it.  And you must show them these terms so they know their rights.

  1132 

  1133   Our method of protecting your rights has two steps: (1) copyright

  1134 the library, and (2) offer you this license which gives you legal

  1135 permission to copy, distribute and/or modify the library.

  1136 

  1137   Also, for each distributor's protection, we want to make certain

  1138 that everyone understands that there is no warranty for this free

  1139 library.  If the library is modified by someone else and passed on, we

  1140 want its recipients to know that what they have is not the original

  1141 version, so that any problems introduced by others will not reflect on

  1142 the original authors' reputations.

  1143 

  1144   Finally, any free program is threatened constantly by software

  1145 patents.  We wish to avoid the danger that companies distributing free

  1146 software will individually obtain patent licenses, thus in effect

  1147 transforming the program into proprietary software.  To prevent this,

  1148 we have made it clear that any patent must be licensed for everyone's

  1149 free use or not licensed at all.

  1150 

  1151   Most GNU software, including some libraries, is covered by the ordinary

  1152 GNU General Public License, which was designed for utility programs.  This

  1153 license, the GNU Library General Public License, applies to certain

  1154 designated libraries.  This license is quite different from the ordinary

  1155 one; be sure to read it in full, and don't assume that anything in it is

  1156 the same as in the ordinary license.

  1157 

  1158   The reason we have a separate public license for some libraries is that

  1159 they blur the distinction we usually make between modifying or adding to a

  1160 program and simply using it.  Linking a program with a library, without

  1161 changing the library, is in some sense simply using the library, and is

  1162 analogous to running a utility program or application program.  However, in

  1163 a textual and legal sense, the linked executable is a combined work, a

  1164 derivative of the original library, and the ordinary General Public License

  1165 treats it as such.

  1166 

  1167   Because of this blurred distinction, using the ordinary General

  1168 Public License for libraries did not effectively promote software

  1169 sharing, because most developers did not use the libraries.  We

  1170 concluded that weaker conditions might promote sharing better.

  1171 

  1172   However, unrestricted linking of non-free programs would deprive the

  1173 users of those programs of all benefit from the free status of the

  1174 libraries themselves.  This Library General Public License is intended to

  1175 permit developers of non-free programs to use free libraries, while

  1176 preserving your freedom as a user of such programs to change the free

  1177 libraries that are incorporated in them.  (We have not seen how to achieve

  1178 this as regards changes in header files, but we have achieved it as regards

  1179 changes in the actual functions of the Library.)  The hope is that this

  1180 will lead to faster development of free libraries.

  1181 

  1182   The precise terms and conditions for copying, distribution and

  1183 modification follow.  Pay close attention to the difference between a

  1184 "work based on the library" and a "work that uses the library".  The

  1185 former contains code derived from the library, while the latter only

  1186 works together with the library.

  1187 

  1188   Note that it is possible for a library to be covered by the ordinary

  1189 General Public License rather than by this special one.

  1190 

  1191                   GNU LIBRARY GENERAL PUBLIC LICENSE

  1192    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

  1193 

  1194   0. This License Agreement applies to any software library which

  1195 contains a notice placed by the copyright holder or other authorized

  1196 party saying it may be distributed under the terms of this Library

  1197 General Public License (also called "this License").  Each licensee is

  1198 addressed as "you".

  1199 

  1200   A "library" means a collection of software functions and/or data

  1201 prepared so as to be conveniently linked with application programs

  1202 (which use some of those functions and data) to form executables.

  1203 

  1204   The "Library", below, refers to any such software library or work

  1205 which has been distributed under these terms.  A "work based on the

  1206 Library" means either the Library or any derivative work under

  1207 copyright law: that is to say, a work containing the Library or a

  1208 portion of it, either verbatim or with modifications and/or translated

  1209 straightforwardly into another language.  (Hereinafter, translation is

  1210 included without limitation in the term "modification".)

  1211 

  1212   "Source code" for a work means the preferred form of the work for

  1213 making modifications to it.  For a library, complete source code means

  1214 all the source code for all modules it contains, plus any associated

  1215 interface definition files, plus the scripts used to control compilation

  1216 and installation of the library.

  1217 

  1218   Activities other than copying, distribution and modification are not

  1219 covered by this License; they are outside its scope.  The act of

  1220 running a program using the Library is not restricted, and output from

  1221 such a program is covered only if its contents constitute a work based

  1222 on the Library (independent of the use of the Library in a tool for

  1223 writing it).  Whether that is true depends on what the Library does

  1224 and what the program that uses the Library does.

  1225   

  1226   1. You may copy and distribute verbatim copies of the Library's

  1227 complete source code as you receive it, in any medium, provided that

  1228 you conspicuously and appropriately publish on each copy an

  1229 appropriate copyright notice and disclaimer of warranty; keep intact

  1230 all the notices that refer to this License and to the absence of any

  1231 warranty; and distribute a copy of this License along with the

  1232 Library.

  1233 

  1234   You may charge a fee for the physical act of transferring a copy,

  1235 and you may at your option offer warranty protection in exchange for a

  1236 fee.

  1237 

  1238   2. You may modify your copy or copies of the Library or any portion

  1239 of it, thus forming a work based on the Library, and copy and

  1240 distribute such modifications or work under the terms of Section 1

  1241 above, provided that you also meet all of these conditions:

  1242 

  1243     a) The modified work must itself be a software library.

  1244 

  1245     b) You must cause the files modified to carry prominent notices

  1246     stating that you changed the files and the date of any change.

  1247 

  1248     c) You must cause the whole of the work to be licensed at no

  1249     charge to all third parties under the terms of this License.

  1250 

  1251     d) If a facility in the modified Library refers to a function or a

  1252     table of data to be supplied by an application program that uses

  1253     the facility, other than as an argument passed when the facility

  1254     is invoked, then you must make a good faith effort to ensure that,

  1255     in the event an application does not supply such function or

  1256     table, the facility still operates, and performs whatever part of

  1257     its purpose remains meaningful.

  1258 

  1259     (For example, a function in a library to compute square roots has

  1260     a purpose that is entirely well-defined independent of the

  1261     application.  Therefore, Subsection 2d requires that any

  1262     application-supplied function or table used by this function must

  1263     be optional: if the application does not supply it, the square

  1264     root function must still compute square roots.)

  1265 

  1266 These requirements apply to the modified work as a whole.  If

  1267 identifiable sections of that work are not derived from the Library,

  1268 and can be reasonably considered independent and separate works in

  1269 themselves, then this License, and its terms, do not apply to those

  1270 sections when you distribute them as separate works.  But when you

  1271 distribute the same sections as part of a whole which is a work based

  1272 on the Library, the distribution of the whole must be on the terms of

  1273 this License, whose permissions for other licensees extend to the

  1274 entire whole, and thus to each and every part regardless of who wrote

  1275 it.

  1276 

  1277 Thus, it is not the intent of this section to claim rights or contest

  1278 your rights to work written entirely by you; rather, the intent is to

  1279 exercise the right to control the distribution of derivative or

  1280 collective works based on the Library.

  1281 

  1282 In addition, mere aggregation of another work not based on the Library

  1283 with the Library (or with a work based on the Library) on a volume of

  1284 a storage or distribution medium does not bring the other work under

  1285 the scope of this License.

  1286 

  1287   3. You may opt to apply the terms of the ordinary GNU General Public

  1288 License instead of this License to a given copy of the Library.  To do

  1289 this, you must alter all the notices that refer to this License, so

  1290 that they refer to the ordinary GNU General Public License, version 2,

  1291 instead of to this License.  (If a newer version than version 2 of the

  1292 ordinary GNU General Public License has appeared, then you can specify

  1293 that version instead if you wish.)  Do not make any other change in

  1294 these notices.

  1295 

  1296   Once this change is made in a given copy, it is irreversible for

  1297 that copy, so the ordinary GNU General Public License applies to all

  1298 subsequent copies and derivative works made from that copy.

  1299 

  1300   This option is useful when you wish to copy part of the code of

  1301 the Library into a program that is not a library.

  1302 

  1303   4. You may copy and distribute the Library (or a portion or

  1304 derivative of it, under Section 2) in object code or executable form

  1305 under the terms of Sections 1 and 2 above provided that you accompany

  1306 it with the complete corresponding machine-readable source code, which

  1307 must be distributed under the terms of Sections 1 and 2 above on a

  1308 medium customarily used for software interchange.

  1309 

  1310   If distribution of object code is made by offering access to copy

  1311 from a designated place, then offering equivalent access to copy the

  1312 source code from the same place satisfies the requirement to

  1313 distribute the source code, even though third parties are not

  1314 compelled to copy the source along with the object code.

  1315 

  1316   5. A program that contains no derivative of any portion of the

  1317 Library, but is designed to work with the Library by being compiled or

  1318 linked with it, is called a "work that uses the Library".  Such a

  1319 work, in isolation, is not a derivative work of the Library, and

  1320 therefore falls outside the scope of this License.

  1321 

  1322   However, linking a "work that uses the Library" with the Library

  1323 creates an executable that is a derivative of the Library (because it

  1324 contains portions of the Library), rather than a "work that uses the

  1325 library".  The executable is therefore covered by this License.

  1326 Section 6 states terms for distribution of such executables.

  1327 

  1328   When a "work that uses the Library" uses material from a header file

  1329 that is part of the Library, the object code for the work may be a

  1330 derivative work of the Library even though the source code is not.

  1331 Whether this is true is especially significant if the work can be

  1332 linked without the Library, or if the work is itself a library.  The
