   355  51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA

   358    explicit claim or by omission.

   356  Everyone is permitted to copy and distribute verbatim copies

   359 

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

   359 			    Preamble

   362 

   360 

   363 4. If PCRE is embedded in any software that is released under the GNU

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

   364    General Purpose Licence (GPL), then the terms of that licence shall

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

   365    supersede any condition above with which it is incompatible.

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

   366 -----------------------------------------------------------------------------

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

   367 

   365 General Public License applies to most of the Free Software

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

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

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

   369 your programs, too.

   370 

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

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

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

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

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

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

   377 

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

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

   380 These restrictions translate to certain responsibilities for you if you

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

   382 

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

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

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

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

   387 rights.

   388 

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

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

   391 distribute and/or modify the software.

   392 

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

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

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

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

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

   398 authors' reputations.

   399 

   400   Finally, any free program is threatened constantly by software

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

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

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

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

   405 

   406   The precise terms and conditions for copying, distribution and

   407 modification follow.

   408 

   409 		    GNU GENERAL PUBLIC LICENSE

   410    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

   411 

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

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

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

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

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

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

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

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

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

   421 

   422 Activities other than copying, distribution and modification are not

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

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

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

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

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

   428 

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

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

   431 conspicuously and appropriately publish on each copy an appropriate

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

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

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

   435 along with the Program.

   436 

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

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

   439 

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

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

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

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

   444 

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

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

   447 

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

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

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

   451     parties under the terms of this License.

   452 

   453     c) If the modified program normally reads commands interactively

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

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

   456     announcement including an appropriate copyright notice and a

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

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

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

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

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

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

   463 

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

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

   466 and can be reasonably considered independent and separate works in

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

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

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

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

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

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

   473 

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

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

   476 exercise the right to control the distribution of derivative or

   477 collective works based on the Program.

   478 

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

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

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

   482 the scope of this License.

   483 

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

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

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

   487 

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

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

   490     1 and 2 above on a medium customarily used for software interchange; or,

   491 

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

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

   494     cost of physically performing source distribution, a complete

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

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

   497     customarily used for software interchange; or,

   498 

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

   500     to distribute corresponding source code.  (This alternative is

   501     allowed only for noncommercial distribution and only if you

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

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

   504 

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

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

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

   508 associated interface definition files, plus the scripts used to

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

   510 special exception, the source code distributed need not include

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

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

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

   514 itself accompanies the executable.

   515 

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

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

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

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

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

   521 

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

   523 except as expressly provided under this License.  Any attempt

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

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

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

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

   528 parties remain in full compliance.

   529 

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

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

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

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

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

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

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

   537 the Program or works based on it.

   538 

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

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

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

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

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

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

   545 this License.

   546 

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

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

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

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

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

   552 distribute so as to satisfy simultaneously your obligations under this

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

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

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

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

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

   558 refrain entirely from distribution of the Program.

   559 

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

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

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

   563 circumstances.

   564 

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

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

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

   568 integrity of the free software distribution system, which is

   569 implemented by public license practices.  Many people have made

   570 generous contributions to the wide range of software distributed

   571 through that system in reliance on consistent application of that

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

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

   574 impose that choice.

   575 

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

   577 be a consequence of the rest of this License.

   578 

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

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

   581 original copyright holder who places the Program under this License

   582 may add an explicit geographical distribution limitation excluding

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

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

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

   586 

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

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

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

   590 address new problems or concerns.

   591 

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

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

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

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

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

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

   598 Foundation.

   599 

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

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

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

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

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

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

   606 of promoting the sharing and reuse of software generally.

   607 

   608 			    NO WARRANTY

   609 

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

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

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

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

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

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

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

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

   618 REPAIR OR CORRECTION.

   619 

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

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

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

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

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

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

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

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

   628 POSSIBILITY OF SUCH DAMAGES.

   629 

   630 		     END OF TERMS AND CONDITIONS

   631 

   632 	    How to Apply These Terms to Your New Programs

   633 

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

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

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

   637 

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

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

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

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

   642 

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

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

   645 

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

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

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

   649     (at your option) any later version.

   650 

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

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

   653     MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the

   654     GNU General Public License for more details.

   655 

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

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

   658     51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.

   659 

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

   661 

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

   663 when it starts in an interactive mode:

   664 

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

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

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

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

   669 

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

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

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

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

   674 

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

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

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

   678 

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

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

   681 

   682   <signature of Ty Coon>, 1 April 1989

   683   Ty Coon, President of Vice

   684 

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

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

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

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

   689 Public License instead of this License.

   690
