    80 		    GNU GENERAL PUBLIC LICENSE
       
    81    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
       
    82 
       
    83   0. This License applies to any program or other work which contains
       
    84 a notice placed by the copyright holder saying it may be distributed
       
    85 under the terms of this General Public License.  The "Program", below,
       
    86 refers to any such program or work, and a "work based on the Program"
       
    87 means either the Program or any derivative work under copyright law:
       
    88 that is to say, a work containing the Program or a portion of it,
       
    89 either verbatim or with modifications and/or translated into another
       
    90 language.  (Hereinafter, translation is included without limitation in
       
    91 the term "modification".)  Each licensee is addressed as "you".
       
    92 
       
    93 Activities other than copying, distribution and modification are not
       
    94 covered by this License; they are outside its scope.  The act of
       
    95 running the Program is not restricted, and the output from the Program
       
    96 is covered only if its contents constitute a work based on the
       
    97 Program (independent of having been made by running the Program).
       
    98 Whether that is true depends on what the Program does.
       
    99 
       
   100   1. You may copy and distribute verbatim copies of the Program's
       
   101 source code as you receive it, in any medium, provided that you
       
   102 conspicuously and appropriately publish on each copy an appropriate
       
   103 copyright notice and disclaimer of warranty; keep intact all the
       
   104 notices that refer to this License and to the absence of any warranty;
       
   105 and give any other recipients of the Program a copy of this License
       
   106 along with the Program.
       
   107 
       
   108 You may charge a fee for the physical act of transferring a copy, and
       
   109 you may at your option offer warranty protection in exchange for a fee.
       
   110 
       
   111   2. You may modify your copy or copies of the Program or any portion
       
   112 of it, thus forming a work based on the Program, and copy and
       
   113 distribute such modifications or work under the terms of Section 1
       
   114 above, provided that you also meet all of these conditions:
       
   115 
       
   116     a) You must cause the modified files to carry prominent notices
       
   117     stating that you changed the files and the date of any change.
       
   118 
       
   119     b) You must cause any work that you distribute or publish, that in
       
   120     whole or in part contains or is derived from the Program or any
       
   121     part thereof, to be licensed as a whole at no charge to all third
       
   122     parties under the terms of this License.
       
   123 
       
   124     c) If the modified program normally reads commands interactively
       
   125     when run, you must cause it, when started running for such
       
   126     interactive use in the most ordinary way, to print or display an
       
   127     announcement including an appropriate copyright notice and a
       
   128     notice that there is no warranty (or else, saying that you provide
       
   129     a warranty) and that users may redistribute the program under
       
   130     these conditions, and telling the user how to view a copy of this
       
   131     License.  (Exception: if the Program itself is interactive but
       
   132     does not normally print such an announcement, your work based on
       
   133     the Program is not required to print an announcement.)
       
   134 
       
   135 These requirements apply to the modified work as a whole.  If
       
   136 identifiable sections of that work are not derived from the Program,
       
   137 and can be reasonably considered independent and separate works in
       
   138 themselves, then this License, and its terms, do not apply to those
       
   139 sections when you distribute them as separate works.  But when you
       
   140 distribute the same sections as part of a whole which is a work based
       
   141 on the Program, the distribution of the whole must be on the terms of
       
   142 this License, whose permissions for other licensees extend to the
       
   143 entire whole, and thus to each and every part regardless of who wrote it.
       
   144 
       
   145 Thus, it is not the intent of this section to claim rights or contest
       
   146 your rights to work written entirely by you; rather, the intent is to
       
   147 exercise the right to control the distribution of derivative or
       
   148 collective works based on the Program.
       
   149 
       
   150 In addition, mere aggregation of another work not based on the Program
       
   151 with the Program (or with a work based on the Program) on a volume of
       
   152 a storage or distribution medium does not bring the other work under
       
   153 the scope of this License.
       
   154 
       
   155   3. You may copy and distribute the Program (or a work based on it,
       
   156 under Section 2) in object code or executable form under the terms of
       
   157 Sections 1 and 2 above provided that you also do one of the following:
       
   158 
       
   159     a) Accompany it with the complete corresponding machine-readable
       
   160     source code, which must be distributed under the terms of Sections
       
   161     1 and 2 above on a medium customarily used for software interchange; or,
       
   162 
       
   163     b) Accompany it with a written offer, valid for at least three
       
   164     years, to give any third party, for a charge no more than your
       
   165     cost of physically performing source distribution, a complete
       
   166     machine-readable copy of the corresponding source code, to be
       
   167     distributed under the terms of Sections 1 and 2 above on a medium
       
   168     customarily used for software interchange; or,
       
   169 
       
   170     c) Accompany it with the information you received as to the offer
       
   171     to distribute corresponding source code.  (This alternative is
       
   172     allowed only for noncommercial distribution and only if you
       
   173     received the program in object code or executable form with such
       
   174     an offer, in accord with Subsection b above.)
       
   175 
       
   176 The source code for a work means the preferred form of the work for
       
   177 making modifications to it.  For an executable work, complete source
       
   178 code means all the source code for all modules it contains, plus any
       
   179 associated interface definition files, plus the scripts used to
       
   180 control compilation and installation of the executable.  However, as a
       
   181 special exception, the source code distributed need not include
       
   182 anything that is normally distributed (in either source or binary
       
   183 form) with the major components (compiler, kernel, and so on) of the
       
   184 operating system on which the executable runs, unless that component
       
   185 itself accompanies the executable.
       
   186 
       
   187 If distribution of executable or object code is made by offering
       
   188 access to copy from a designated place, then offering equivalent
       
   189 access to copy the source code from the same place counts as
       
   190 distribution of the source code, even though third parties are not
       
   191 compelled to copy the source along with the object code.
       
   192 
       
   193   4. You may not copy, modify, sublicense, or distribute the Program
       
   194 except as expressly provided under this License.  Any attempt
       
   195 otherwise to copy, modify, sublicense or distribute the Program is
       
   196 void, and will automatically terminate your rights under this License.
       
   197 However, parties who have received copies, or rights, from you under
       
   198 this License will not have their licenses terminated so long as such
       
   199 parties remain in full compliance.
       
   200 
       
   201   5. You are not required to accept this License, since you have not
       
   202 signed it.  However, nothing else grants you permission to modify or
       
   203 distribute the Program or its derivative works.  These actions are
       
   204 prohibited by law if you do not accept this License.  Therefore, by
       
   205 modifying or distributing the Program (or any work based on the
       
   206 Program), you indicate your acceptance of this License to do so, and
       
   207 all its terms and conditions for copying, distributing or modifying
       
   208 the Program or works based on it.
       
   209 
       
   210   6. Each time you redistribute the Program (or any work based on the
       
   211 Program), the recipient automatically receives a license from the
       
   212 original licensor to copy, distribute or modify the Program subject to
       
   213 these terms and conditions.  You may not impose any further
       
   214 restrictions on the recipients' exercise of the rights granted herein.
       
   215 You are not responsible for enforcing compliance by third parties to
       
   216 this License.
       
   217 
       
   218   7. If, as a consequence of a court judgment or allegation of patent
       
   219 infringement or for any other reason (not limited to patent issues),
       
   220 conditions are imposed on you (whether by court order, agreement or
       
   221 otherwise) that contradict the conditions of this License, they do not
       
   222 excuse you from the conditions of this License.  If you cannot
       
   223 distribute so as to satisfy simultaneously your obligations under this
       
   224 License and any other pertinent obligations, then as a consequence you
       
   225 may not distribute the Program at all.  For example, if a patent
       
   226 license would not permit royalty-free redistribution of the Program by
       
   227 all those who receive copies directly or indirectly through you, then
       
   228 the only way you could satisfy both it and this License would be to
       
   229 refrain entirely from distribution of the Program.
       
   230 
       
   231 If any portion of this section is held invalid or unenforceable under
       
   232 any particular circumstance, the balance of the section is intended to
       
   233 apply and the section as a whole is intended to apply in other
       
   234 circumstances.
       
   235 
       
   236 It is not the purpose of this section to induce you to infringe any
       
   237 patents or other property right claims or to contest validity of any
       
   238 such claims; this section has the sole purpose of protecting the
       
   239 integrity of the free software distribution system, which is
       
   240 implemented by public license practices.  Many people have made
       
   241 generous contributions to the wide range of software distributed
       
   242 through that system in reliance on consistent application of that
       
   243 system; it is up to the author/donor to decide if he or she is willing
       
   244 to distribute software through any other system and a licensee cannot
       
   245 impose that choice.
       
   246 
       
   247 This section is intended to make thoroughly clear what is believed to
       
   248 be a consequence of the rest of this License.
       
   249 
       
   250   8. If the distribution and/or use of the Program is restricted in
       
   251 certain countries either by patents or by copyrighted interfaces, the
       
   252 original copyright holder who places the Program under this License
       
   253 may add an explicit geographical distribution limitation excluding
       
   254 those countries, so that distribution is permitted only in or among
       
   255 countries not thus excluded.  In such case, this License incorporates
       
   256 the limitation as if written in the body of this License.
       
   257 
       
   258   9. The Free Software Foundation may publish revised and/or new versions
       
   259 of the General Public License from time to time.  Such new versions will
       
   260 be similar in spirit to the present version, but may differ in detail to
       
   261 address new problems or concerns.
       
   262 
       
   263 Each version is given a distinguishing version number.  If the Program
       
   264 specifies a version number of this License which applies to it and "any

   303 	    How to Apply These Terms to Your New Programs
       
   304 
       
   305   If you develop a new program, and you want it to be of the greatest
       
   306 possible use to the public, the best way to achieve this is to make it
       
   307 free software which everyone can redistribute and change under these terms.
       
   308 
       
   309   To do so, attach the following notices to the program.  It is safest
       
   310 to attach them to the start of each source file to most effectively
       
   311 convey the exclusion of warranty; and each file should have at least
       
   312 the "copyright" line and a pointer to where the full notice is found.
       
   313 
       
   314     <one line to give the program's name and a brief idea of what it does.>

By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too. 
       
   538 When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things. 
       
   539 To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it. 
       
   540 For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. 
       
   541 We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. 
       
   542 Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. 
       
   543 Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. 
       
   544 The precise terms and conditions for copying, distribution and modification follow. 
       
   545 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
       
   546 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". 
       
   547 Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does. 
       
   548 1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program. 
       
   549 You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 
       
   550 2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: 
       
   551 a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change. 
       
   552 b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License. 
       
   553 c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.) 
       
   554 These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. 
       
   555 Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program. 
       
   556 In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 
       
   557 3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following: 
       
   558 a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, 
       
   559 b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or, 
       
   560 c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.) 
       
   561 The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. 
       
   562 If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code. 
       
   563 4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 
       
   564 5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it. 
       
   565 6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License. 
       
   566 7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program. 
       
   567 If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances. 
       
   568 It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. 
       
   569 This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 
       
   570 8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 
       
   571 9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. 
       
   572 Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation. 
       
   573 10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. 
       
   574 NO WARRANTY
       
   575 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 
       
   576 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 
       
   577 END OF TERMS AND CONDITIONS
       
   578 How to Apply These Terms to Your New Programs
       
   579 If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms. 
       
   580 To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. 
       
   581 one line to give the program's name and an idea of what it does.
       
   582 Copyright (C) yyyy  name of author
       
   583 
       
   584 This program is free software; you can redistribute it and/or
       
   585 modify it under the terms of the GNU General Public License
       
   586 as published by the Free Software Foundation; either version 2
       
   587 of the License, or (at your option) any later version.
       
   588 
       
   589 This program is distributed in the hope that it will be useful,
       
   590 but WITHOUT ANY WARRANTY; without even the implied warranty of
       
   591 MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
       
   592 GNU General Public License for more details.
       
   593 
       
   594 You should have received a copy of the GNU General Public License
       
   595 along with this program; if not, write to the Free Software
       
   596 Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA.
       
   597 Also add information on how to contact you by electronic and paper mail. 
       
   598 If the program is interactive, make it output a short notice like this when it starts in an interactive mode: 
       
   599 Gnomovision version 69, Copyright (C) year name of author
       
   600 Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
       
   601 type `show w'.  This is free software, and you are welcome
       
   602 to redistribute it under certain conditions; type `show c' 
       
   603 for details.
       
   604 The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program. 
       
   605 You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names: 
       
   606 Yoyodyne, Inc., hereby disclaims all copyright
       
   607 interest in the program `Gnomovision'

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

   623 [This is the first released version of the Lesser GPL.  It also counts
       
   624  as the successor of the GNU Library Public License, version 2, hence
       
   625  the version number 2.1.]
       
   626 Preamble
       
   627 The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. 
       
   628 This license, the Lesser General Public License, applies to some specially designated software packages--typically libraries--of the Free Software Foundation and other authors who decide to use it. You can use it too, but we suggest you first think carefully about whether this license or the ordinary General Public License is the better strategy to use in any particular case, based on the explanations below. 
       
   629 When we speak of free software, we are referring to freedom of use, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish); that you receive source code or can get it if you want it; that you can change the software and use pieces of it in new free programs; and that you are informed that you can do these things. 
       
   630 To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you distribute copies of the library or if you modify it. 
       
   631 For example, if you distribute copies of the library, whether gratis or for a fee, you must give the recipients all the rights that we gave you. You must make sure that they, too, receive or can get the source code. If you link other code with the library, you must provide complete object files to the recipients, so that they can relink them with the library after making changes to the library and recompiling it. And you must show them these terms so they know their rights. 
       
   632 We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this license, which gives you legal permission to copy, distribute and/or modify the library. 
       
   633 To protect each distributor, we want to make it very clear that there is no warranty for the free library. Also, if the library is modified by someone else and passed on, the recipients should know that what they have is not the original version, so that the original author's reputation will not be affected by problems that might be introduced by others. 
       
   634 Finally, software patents pose a constant threat to the existence of any free program. We wish to make sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive license from a patent holder. Therefore, we insist that any patent license obtained for a version of the library must be consistent with the full freedom of use specified in this license. 
       
   635 Most GNU software, including some libraries, is covered by the ordinary GNU General Public License. This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite different from the ordinary General Public License. We use this license for certain libraries in order to permit linking those libraries into non-free programs. 
       
   636 When a program is linked with a library, whether statically or using a shared library, the combination of the two is legally speaking a combined work, a derivative of the original library. The ordinary General Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The Lesser General Public License permits more lax criteria for linking other code with the library. 
       
   637 We call this license the "Lesser" General Public License because it does Less to protect the user's freedom than the ordinary General Public License. It also provides other free software developers Less of an advantage over competing non-free programs. These disadvantages are the reason we use the ordinary General Public License for many libraries. However, the Lesser license provides advantages in certain special circumstances. 
       
   638 For example, on rare occasions, there may be a special need to encourage the widest possible use of a certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be allowed to use the library. A more frequent case is that a free library does the same job as widely used non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we use the Lesser General Public License. 
       
   639 In other cases, permission to use a particular library in non-free programs enables a greater number of people to use a large body of free software. For example, permission to use the GNU C Library in non-free programs enables many more people to use the whole GNU operating system, as well as its variant, the GNU/Linux operating system. 
       
   640 Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that the user of a program that is linked with the Library has the freedom and the wherewithal to run that program using a modified version of the Library. 
       
   641 The precise terms and conditions for copying, distribution and modification follow. Pay close attention to the difference between a "work based on the library" and a "work that uses the library". The former contains code derived from the library, whereas the latter must be combined with the library in order to run. 
       
   642 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
       
   643 0. This License Agreement applies to any software library or other program which contains a notice placed by the copyright holder or other authorized party saying it may be distributed under the terms of this Lesser General Public License (also called "this License"). Each licensee is addressed as "you". 
       
   644 A "library" means a collection of software functions and/or data prepared so as to be conveniently linked with application programs (which use some of those functions and data) to form executables. 
       
   645 The "Library", below, refers to any such software library or work which has been distributed under these terms. A "work based on the Library" means either the Library or any derivative work under copyright law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications and/or translated straightforwardly into another language. (Hereinafter, translation is included without limitation in the term "modification".) 
       
   646 "Source code" for a work means the preferred form of the work for making modifications to it. For a library, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the library. 
       
   647 Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running a program using the Library is not restricted, and output from such a program is covered only if its contents constitute a work based on the Library (independent of the use of the Library in a tool for writing it). Whether that is true depends on what the Library does and what the program that uses the Library does. 
       
   648 1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and distribute a copy of this License along with the Library. 
       
   649 You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee. 
       
   650 2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on the Library, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions: 
       
   651 a) The modified work must itself be a software library. 
       
   652 b) You must cause the files modified to carry prominent notices stating that you changed the files and the date of any change. 
       
   653 c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms of this License. 
       
   654 d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application program that uses the facility, other than as an argument passed when the facility is invoked, then you must make a good faith effort to ensure that, in the event an application does not supply such function or table, the facility still operates, and performs whatever part of its purpose remains meaningful. 
       
   655 (For example, a function in a library to compute square roots has a purpose that is entirely well-defined independent of the application. Therefore, Subsection 2d requires that any application-supplied function or table used by this function must be optional: if the application does not supply it, the square root function must still compute square roots.)
       
   656 These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Library, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Library, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it. 
       
   657 Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Library. 
       
   658 In addition, mere aggregation of another work not based on the Library with the Library (or with a work based on the Library) on a volume of a storage or distribution medium does not bring the other work under the scope of this License. 
       
   659 3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer version than version 2 of the ordinary GNU General Public License has appeared, then you can specify that version instead if you wish.) Do not make any other change in these notices. 
       
   660 Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General Public License applies to all subsequent copies and derivative works made from that copy. 
       
   661 This option is useful when you wish to copy part of the code of the Library into a program that is not a library. 
       
   662 4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange. 
       
   663 If distribution of object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place satisfies the requirement to distribute the source code, even though third parties are not compelled to copy the source along with the object code. 
       
   664 5. A program that contains no derivative of any portion of the Library, but is designed to work with the Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License. 
       
   665 However, linking a "work that uses the Library" with the Library creates an executable that is a derivative of the Library (because it contains portions of the Library), rather than a "work that uses the library". The executable is therefore covered by this License. Section 6 states terms for distribution of such executables. 
       
   666 When a "work that uses the Library" uses material from a header file that is part of the Library, the object code for the work may be a derivative work of the Library even though the source code is not. Whether this is true is especially significant if the work can be linked without the Library, or if the work is itself a library. The threshold for this to be true is not precisely defined by law. 
       
   667 If such an object file uses only numerical parameters, data structure layouts and accessors, and small macros and small inline functions (ten lines or less in length), then the use of the object file is unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object code plus portions of the Library will still fall under Section 6.) 
       
   668 Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not they are linked directly with the Library itself. 
       
   669 6. As an exception to the Sections above, you may also combine or link a "work that uses the Library" with the Library to produce a work containing portions of the Library, and distribute that work under terms of your choice, provided that the terms permit modification of the work for the customer's own use and reverse engineering for debugging such modifications. 
       
   670 You must give prominent notice with each copy of the work that the Library is used in it and that the Library and its use are covered by this License. You must supply a copy of this License. If the work during execution displays copyright notices, you must include the copyright notice for the Library among them, as well as a reference directing the user to the copy of this License. Also, you must do one of these things: 
       
   671 a) Accompany the work with the complete corresponding machine-readable source code for the Library including whatever changes were used in the work (which must be distributed under Sections 1 and 2 above); and, if the work is an executable linked with the Library, with the complete machine-readable "work that uses the Library", as object code and/or source code, so that the user can modify the Library and then relink to produce a modified executable containing the modified Library. (It is understood that the user who changes the contents of definitions files in the Library will not necessarily be able to recompile the application to use the modified definitions.) 
       
   672 b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with. 
       
   673 c) Accompany the work with a written offer, valid for at least three years, to give the same user the materials specified in Subsection 6a, above, for a charge no more than the cost of performing this distribution. 
       
   674 d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent access to copy the above specified materials from the same place. 
       
   675 e) Verify that the user has already received a copy of these materials or that you have already sent this user a copy. 
       
   676 For an executable, the required form of the "work that uses the Library" must include any data and utility programs needed for reproducing the executable from it. However, as a special exception, the materials to be distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable. 
       
   677 It may happen that this requirement contradicts the license restrictions of other proprietary libraries that do not normally accompany the operating system. Such a contradiction means you cannot use both them and the Library together in an executable that you distribute. 
       
   678 7. You may place library facilities that are a work based on the Library side-by-side in a single library together with other library facilities not covered by this License, and distribute such a combined library, provided that the separate distribution of the work based on the Library and of the other library facilities is otherwise permitted, and provided that you do these two things: 
       
   679 a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities. This must be distributed under the terms of the Sections above. 
       
   680 b) Give prominent notice with the combined library of the fact that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 
       
   681 8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance. 
       
   682 9. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Library or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or any work based on the Library), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Library or works based on it. 
       
   683 10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically receives a license from the original licensor to copy, distribute, link with or modify the Library subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties with this License. 
       
   684 11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For example, if a patent license would not permit royalty-free redistribution of the Library by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Library. 
       
   685 If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply, and the section as a whole is intended to apply in other circumstances. 
       
   686 It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice. 
       
   687 This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License. 
       
   688 12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Library under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License. 
       
   689 13. The Free Software Foundation may publish revised and/or new versions of the Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. 
       
   690 Each version is given a distinguishing version number. If the Library specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Library does not specify a license version number, you may choose any version ever published by the Free Software Foundation. 
       
   691 14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions are incompatible with these, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally. 
       
   692 NO WARRANTY 
       
   693 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. 
       
   694 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. 
       
   695 END OF TERMS AND CONDITIONS
       
   696 How to Apply These Terms to Your New Libraries
       
   697 If you develop a new library, and you want it to be of the greatest possible use to the public, we recommend making it free software that everyone can redistribute and change. You can do so by permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General Public License). 
       
   698 To apply these terms, attach the following notices to the library. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found. 
       
   699 one line to give the library's name and an idea of what it does.

   726 Artistic License 2.0
       
   727 Copyright (c) 2000-2006, The Perl Foundation.
       
   728 Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
       
   729 Preamble
       
   730 This license establishes the terms under which a given free software Package may be copied, modified, distributed, and/or redistributed. The intent is that the Copyright Holder maintains some artistic control over the development of that Package while still keeping the Package available as open source and free software.
       
   731 You are always permitted to make arrangements wholly outside of this license directly with the Copyright Holder of a given Package. If the terms of this license do not permit the full use that you propose to make of the Package, you should contact the Copyright Holder and seek a different licensing arrangement.
       
   732 Definitions
       
   733 "Copyright Holder" means the individual(s) or organization(s) named in the copyright notice for the entire Package.
       
   734 "Contributor" means any party that has contributed code or other material to the Package, in accordance with the Copyright Holder's procedures.
       
   735 "You" and "your" means any person who would like to copy, distribute, or modify the Package.
       
   736 "Package" means the collection of files distributed by the Copyright Holder, and derivatives of that collection and/or of those files. A given Package may consist of either the Standard Version, or a Modified Version.
       
   737 "Distribute" means providing a copy of the Package or making it accessible to anyone else, or in the case of a company or organization, to others outside of your company or organization.
       
   738 "Distributor Fee" means any fee that you charge for Distributing this Package or providing support for this Package to another party. It does not mean licensing fees.
       
   739 "Standard Version" refers to the Package if it has not been modified, or has been modified only in ways explicitly requested by the Copyright Holder.
       
   740 "Modified Version" means the Package, if it has been changed, and such changes were not explicitly requested by the Copyright Holder.
       
   741 "Original License" means this Artistic License as Distributed with the Standard Version of the Package, in its current version or as it may be modified by The Perl Foundation in the future.
       
   742 "Source" form means the source code, documentation source, and configuration files for the Package.
       
   743 "Compiled" form means the compiled bytecode, object code, binary, or any other form resulting from mechanical transformation or translation of the Source form.
       
   744 Permission for Use and Modification Without Distribution
       
   745 (1) You are permitted to use the Standard Version and create and use Modified Versions for any purpose without restriction, provided that you do not Distribute the Modified Version.
       
   746 Permissions for Redistribution of the Standard Version
       
   747 (2) You may Distribute verbatim copies of the Source form of the Standard Version of this Package in any medium without restriction, either gratis or for a Distributor Fee, provided that you duplicate all of the original copyright notices and associated disclaimers. At your discretion, such verbatim copies may or may not include a Compiled form of the Package.
       
   748 (3) You may apply any bug fixes, portability changes, and other modifications made available from the Copyright Holder. The resulting Package will still be considered the Standard Version, and as such will be subject to the Original License.
       
   749 Distribution of Modified Versions of the Package as Source
       
   750 (4) You may Distribute your Modified Version as Source (either gratis or for a Distributor Fee, and with or without a Compiled form of the Modified Version) provided that you clearly document how it differs from the Standard Version, including, but not limited to, documenting any non-standard features, executables, or modules, and provided that you do at least ONE of the following:
       
   751 (a) make the Modified Version available to the Copyright Holder of the Standard Version, under the Original License, so that the Copyright Holder may include your modifications in the Standard Version.
       
   752 (b) ensure that installation of your Modified Version does not prevent the user installing or running the Standard Version. In addition, the Modified Version must bear a name that is different from the name of the Standard Version.
       
   753 (c) allow anyone who receives a copy of the Modified Version to make the Source form of the Modified Version available to others under
       
   754 (i) the Original License or
       
   755 (ii) a license that permits the licensee to freely copy, modify and redistribute the Modified Version using the same licensing terms that apply to the copy that the licensee received, and requires that the Source form of the Modified Version, and of any works derived from it, be made freely available in that license fees are prohibited but Distributor Fees are allowed.
       
   756 Distribution of Compiled Forms of the Standard Version or Modified Versions without the Source
       
   757 (5) You may Distribute Compiled forms of the Standard Version without the Source, provided that you include complete instructions on how to get the Source of the Standard Version. Such instructions must be valid at the time of your distribution. If these instructions, at any time while you are carrying out such distribution, become invalid, you must provide new instructions on demand or cease further distribution. If you provide valid instructions or cease distribution within thirty days after you become aware that the instructions are invalid, then you do not forfeit any of your rights under this license.
       
   758 (6) You may Distribute a Modified Version in Compiled form without the Source, provided that you comply with Section 4 with respect to the Source of the Modified Version.
       
   759 Aggregating or Linking the Package
       
   760 (7) You may aggregate the Package (either the Standard Version or Modified Version) with other packages and Distribute the resulting aggregation provided that you do not charge a licensing fee for the Package. Distributor Fees are permitted, and licensing fees for other components in the aggregation are permitted. The terms of this license apply to the use and Distribution of the Standard or Modified Versions as included in the aggregation.
       
   761 (8) You are permitted to link Modified and Standard Versions with other works, to embed the Package in a larger work of your own, or to build stand-alone binary or bytecode versions of applications that include the Package, and Distribute the result without restriction, provided the result does not expose a direct interface to the Package.
       
   762 Items That are Not Considered Part of a Modified Version
       
   763 (9) Works (including, but not limited to, modules and scripts) that merely extend or make use of the Package, do not, by themselves, cause the Package to be a Modified Version. In addition, such works are not considered parts of the Package itself, and are not subject to the terms of this license.
       
   764 General Provisions
       
   765 (10) Any use, modification, and distribution of the Standard or Modified Versions is governed by this Artistic License. By using, modifying or distributing the Package, you accept this license. Do not use, modify, or distribute the Package, if you do not accept this license.
       
   766 (11) If your Modified Version has been derived from a Modified Version made by someone other than you, you are nevertheless required to ensure that your Modified Version complies with the requirements of this license.
       
   767 (12) This license does not grant you the right to use any trademark, service mark, tradename, or logo of the Copyright Holder.
       
   768 (13) This license includes the non-exclusive, worldwide, free-of-charge patent license to make, have made, use, offer to sell, sell, import and otherwise transfer the Package with respect to any patent claims licensable by the Copyright Holder that are necessarily infringed by the Package. If you institute patent litigation (including a cross-claim or counterclaim) against any party alleging that the Package constitutes direct or contributory patent infringement, then this Artistic License to you shall terminate on the date that such litigation is filed.
       
   769 (14) Disclaimer of Warranty: THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. THE IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT PERMITTED BY YOUR LOCAL LAW. UNLESS REQUIRED BY LAW, NO COPYRIGHT HOLDER OR CONTRIBUTOR WILL BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE, EVEN IF ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.
