     6  Everyone is permitted to copy and distribute verbatim copies

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

     8 

     9 			    Preamble

    10 

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

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

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

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

    15 General Public License applies to most of the Free Software

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

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

    18 the GNU Library General Public License instead.)  You can apply it to

    19 your programs, too.

    20 

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

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

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

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

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

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

    27 

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

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

    30 These restrictions translate to certain responsibilities for you if you

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

    32 

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

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

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

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

    37 rights.

    38 

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

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

    41 distribute and/or modify the software.

    42 

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

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

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

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

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

    48 authors' reputations.

    49 

    50   Finally, any free program is threatened constantly by software

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

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

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

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

    55 

    56   The precise terms and conditions for copying, distribution and

    57 modification follow.

    58 

    59 		    GNU GENERAL PUBLIC LICENSE

    60    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

    61 

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

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

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

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

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

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

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

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

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

    71 

    72 Activities other than copying, distribution and modification are not

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

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

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

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

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

    78 

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

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

    81 conspicuously and appropriately publish on each copy an appropriate

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

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

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

    85 along with the Program.

    86 

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

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

    89 

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

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

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

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

    94 

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

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

    97 

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

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

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

   101     parties under the terms of this License.

   102 

   103     c) If the modified program normally reads commands interactively

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

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

   106     announcement including an appropriate copyright notice and a

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

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

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

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

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

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

   113 

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

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

   116 and can be reasonably considered independent and separate works in

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

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

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

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

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

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

   123 

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

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

   126 exercise the right to control the distribution of derivative or

   127 collective works based on the Program.

   128 

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

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

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

   132 the scope of this License.

   133 

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

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

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

   137 

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

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

   140     1 and 2 above on a medium customarily used for software interchange; or,

   141 

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

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

   144     cost of physically performing source distribution, a complete

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

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

   147     customarily used for software interchange; or,

   148 

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

   150     to distribute corresponding source code.  (This alternative is

   151     allowed only for noncommercial distribution and only if you

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

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

   154 

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

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

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

   158 associated interface definition files, plus the scripts used to

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

   160 special exception, the source code distributed need not include

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

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

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

   164 itself accompanies the executable.

   165 

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

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

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

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

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

   171 

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

   173 except as expressly provided under this License.  Any attempt

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

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

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

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

   178 parties remain in full compliance.

   179 

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

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

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

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

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

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

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

   187 the Program or works based on it.

   188 

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

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

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

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

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

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

   195 this License.

   196 

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

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

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

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

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

   202 distribute so as to satisfy simultaneously your obligations under this

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

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

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

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

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

   208 refrain entirely from distribution of the Program.

   209 

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

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

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

   213 circumstances.

   214 

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

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

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

   218 integrity of the free software distribution system, which is

   219 implemented by public license practices.  Many people have made

   220 generous contributions to the wide range of software distributed

   221 through that system in reliance on consistent application of that

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

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

   224 impose that choice.

   225 

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

   227 be a consequence of the rest of this License.

   228 

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

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

   231 original copyright holder who places the Program under this License

   232 may add an explicit geographical distribution limitation excluding

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

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

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

   236 

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

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

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

   240 address new problems or concerns.

   241 

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

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

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

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

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

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

   248 Foundation.

   249 

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

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

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

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

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

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

   256 of promoting the sharing and reuse of software generally.

   257 

   258 			    NO WARRANTY

   259 

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

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

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

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

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

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

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

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

   268 REPAIR OR CORRECTION.

   269 

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

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

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

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

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

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

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

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

   278 POSSIBILITY OF SUCH DAMAGES.

   279 

   280 		     END OF TERMS AND CONDITIONS

   281 

   282 	    How to Apply These Terms to Your New Programs

   283 

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

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

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

   287 

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

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

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

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

   292 

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

   294     Copyright (C) 19yy  <name of author>

   295 

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

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

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

   299     (at your option) any later version.

   300 

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

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

   303     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

   304     GNU General Public License for more details.

   305 

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

   307     along with this program; if not, write to the Free Software

   308     Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA  02110-1301  USA

   309 

   310 

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

   312 

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

   314 when it starts in an interactive mode:

   315 

   316     Gnomovision version 69, Copyright (C) 19yy name of author

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

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

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

   320 

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

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

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

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

   325 

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

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

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

   329 

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

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

   335 

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

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

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

   339 library.  If this is what you want to do, use the GNU Library General

   340 Public License instead of this License.

   344 		  GNU LIBRARY GENERAL PUBLIC LICENSE

   345 		       Version 2, June 1991

   346 

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

   348                     51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA

   349  Everyone is permitted to copy and distribute verbatim copies

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

   351 

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

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

   354 

   355 			    Preamble

   356 

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

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

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

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

   361 

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

   363 specially designated Free Software Foundation software, and to any

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

   365 your libraries, too.

   366 

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

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

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

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

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

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

   373 

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

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

   376 These restrictions translate to certain responsibilities for you if

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

   378 

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

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

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

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

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

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

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

   386 

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

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

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

   390 

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

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

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

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

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

   396 the original authors' reputations.

   397 

   398   Finally, any free program is threatened constantly by software

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

   400 software will individually obtain patent licenses, thus in effect

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

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

   403 free use or not licensed at all.

   404 

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

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

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

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

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

   410 the same as in the ordinary license.

   411 

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

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

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

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

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

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

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

   419 treats it as such.

   420 

   421   Because of this blurred distinction, using the ordinary General

   422 Public License for libraries did not effectively promote software

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

   424 concluded that weaker conditions might promote sharing better.

   425 

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

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

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

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

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

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

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

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

   434 will lead to faster development of free libraries.

   435 

   436   The precise terms and conditions for copying, distribution and

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

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

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

   440 works together with the library.

   441 

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

   443 General Public License rather than by this special one.

   444 

   445 		  GNU LIBRARY GENERAL PUBLIC LICENSE

   446    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

   447 

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

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

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

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

   452 addressed as "you".

   453 

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

   455 prepared so as to be conveniently linked with application programs

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

   457 

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

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

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

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

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

   463 straightforwardly into another language.  (Hereinafter, translation is

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

   465 

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

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

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

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

   470 and installation of the library.

   471 

   472   Activities other than copying, distribution and modification are not

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

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

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

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

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

   478 and what the program that uses the Library does.

   479   

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

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

   482 you conspicuously and appropriately publish on each copy an

   483 appropriate copyright notice and disclaimer of warranty; keep intact

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

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

   486 Library.

   487 

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

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

   490 fee.

   491 

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

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

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

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

   496 

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

   498 

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

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

   501 

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

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

   504 

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

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

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

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

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

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

   511     its purpose remains meaningful.

   512 

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

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

   515     application.  Therefore, Subsection 2d requires that any

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

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

   518     root function must still compute square roots.)

   519 

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

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

   522 and can be reasonably considered independent and separate works in

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

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

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

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

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

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

   529 it.

   530 

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

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

   533 exercise the right to control the distribution of derivative or

   534 collective works based on the Library.

   535 

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

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

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

   539 the scope of this License.

   540 

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

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

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

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

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

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

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

   548 these notices.

   549 

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

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

   552 subsequent copies and derivative works made from that copy.

   553 

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

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

   556 

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

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

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

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

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

   562 medium customarily used for software interchange.

   563 

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

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

   566 source code from the same place satisfies the requirement to

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

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

   569 

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

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

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

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

   574 therefore falls outside the scope of this License.

   575 

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

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

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

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

   580 Section 6 states terms for distribution of such executables.

   581 

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

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

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

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

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

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

   588 

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

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

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

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

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

   594 Library will still fall under Section 6.)

   595 

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

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

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

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

   600 

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

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

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

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

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

   606 engineering for debugging such modifications.

   607 

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

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

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

   611 during execution displays copyright notices, you must include the

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

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

   614 of these things:

   615 

   616     a) Accompany the work with the complete corresponding

   617     machine-readable source code for the Library including whatever

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

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

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

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

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

   623     executable containing the modified Library.  (It is understood

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

   625     Library will not necessarily be able to recompile the application

   626     to use the modified definitions.)

   627 

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

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

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

   631     than the cost of performing this distribution.

   632 

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

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

   635     specified materials from the same place.

   636 

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

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

   639 

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

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

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

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

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

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

   646 which the executable runs, unless that component itself accompanies

   647 the executable.

   648 

   649   It may happen that this requirement contradicts the license

   650 restrictions of other proprietary libraries that do not normally

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

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

   653 distribute.

   654 

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

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

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

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

   659 the Library and of the other library facilities is otherwise

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

   661 

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

   663     based on the Library, uncombined with any other library

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

   665     Sections above.

   666 

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

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

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

   670 

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

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

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

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

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

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

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

   678 

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

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

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

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

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

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

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

   686 the Library or works based on it.

   687 

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

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

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

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

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

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

   694 this License.

   695 

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

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

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

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

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

   701 distribute so as to satisfy simultaneously your obligations under this

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

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

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

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

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

   707 refrain entirely from distribution of the Library.

   708 

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

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

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

   712 

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

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

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

   716 integrity of the free software distribution system which is

   717 implemented by public license practices.  Many people have made

   718 generous contributions to the wide range of software distributed

   719 through that system in reliance on consistent application of that

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

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

   722 impose that choice.

   723 

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

   725 be a consequence of the rest of this License.

   726 

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

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

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

   730 an explicit geographical distribution limitation excluding those countries,

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

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

   733 written in the body of this License.

   734 

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

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

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

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

   739 

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

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

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

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

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

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

   746 the Free Software Foundation.

   747 

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

   749 programs whose distribution conditions are incompatible with these,

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

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

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

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

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

   755 and reuse of software generally.

   756 

   757 			    NO WARRANTY

   758 

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

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

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

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

   763 KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE

   764 IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR

   765 PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE

   766 LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME

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

   768 

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

   770 WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY

   771 AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU

   772 FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR

   773 CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE

   774 LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING

   775 RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A

   776 FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF

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

   778 DAMAGES.

   779 

   780 		     END OF TERMS AND CONDITIONS

   781 

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

   783 

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

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

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

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

   788 ordinary General Public License).

   789 

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

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

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

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

   794 

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

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

   797 

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

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

   800     License as published by the Free Software Foundation; either

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

   802 

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

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

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

   806     Library General Public License for more details.

   807 

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

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

   810     Software Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301, USA.

   811 

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

   813 

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

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

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

   817 

   818   Yoyodyne, Inc., hereby disclaims all copyright interest in the

   819   library `Frob' (a library for tweaking knobs) written by James Random Hacker.
