DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN +ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS INFORMATION ON AN +"AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES REGARDING THE USE OF THIS +DOCUMENT OR THE INFORMATION OR WORKS PROVIDED HEREUNDER, AND DISCLAIMS +LIABILITY FOR DAMAGES RESULTING FROM THE USE OF THIS DOCUMENT OR THE +INFORMATION OR WORKS PROVIDED HEREUNDER. + +Statement of Purpose + +The laws of most jurisdictions throughout the world automatically confer +exclusive Copyright and Related Rights (defined below) upon the creator and +subsequent owner(s) (each and all, an "owner") of an original work of +authorship and/or a database (each, a "Work"). + +Certain owners wish to permanently relinquish those rights to a Work for the +purpose of contributing to a commons of creative, cultural and scientific works +("Commons") that the public can reliably and without fear of later claims of +infringement build upon, modify, incorporate in other works, reuse and +redistribute as freely as possible in any form whatsoever and for any purposes, +including without limitation commercial purposes. These owners may contribute +to the Commons to promote the ideal of a free culture and the further +production of creative, cultural and scientific works, or to gain reputation or +greater distribution for their Work in part through the use and efforts of +others. + +For these and/or other purposes and motivations, and without any expectation of +additional consideration or compensation, the person associating CC0 with a +Work (the "Affirmer"), to the extent that he or she is an owner of Copyright +and Related Rights in the Work, voluntarily elects to apply CC0 to the Work and +publicly distribute the Work under its terms, with knowledge of his or her +Copyright and Related Rights in the Work and the meaning and intended legal +effect of CC0 on those rights. + + 1. Copyright and Related Rights. A Work made available under CC0 may be + protected by copyright and related or neighboring rights ("Copyright and + Related Rights"). Copyright and Related Rights include, but are not limited + to, the following: + + i. the right to reproduce, adapt, distribute, perform, display, + communicate, and translate a Work; + + ii. moral rights retained by the original author(s) and/or performer(s); + + iii. publicity and privacy rights pertaining to a person's image or + likeness depicted in a Work; + + iv. rights protecting against unfair competition in regards to a Work, + subject to the limitations in paragraph 4(a), below; + + v. rights protecting the extraction, dissemination, use and reuse of data + in a Work; + + vi. database rights (such as those arising under Directive 96/9/EC of the + European Parliament and of the Council of 11 March 1996 on the legal + protection of databases, and under any national implementation thereof, + including any amended or successor version of such directive); and + + vii. other similar, equivalent or corresponding rights throughout the + world based on applicable law or treaty, and any national implementations + thereof. + + 2. Waiver. To the greatest extent permitted by, but not in contravention of, + applicable law, Affirmer hereby overtly, fully, permanently, irrevocably and + unconditionally waives, abandons, and surrenders all of Affirmer's Copyright + and Related Rights and associated claims and causes of action, whether now + known or unknown (including existing as well as future claims and causes of + action), in the Work (i) in all territories worldwide, (ii) for the maximum + duration provided by applicable law or treaty (including future time + extensions), (iii) in any current or future medium and for any number of + copies, and (iv) for any purpose whatsoever, including without limitation + commercial, advertising or promotional purposes (the "Waiver"). Affirmer + makes the Waiver for the benefit of each member of the public at large and + to the detriment of Affirmer's heirs and successors, fully intending that + such Waiver shall not be subject to revocation, rescission, cancellation, + termination, or any other legal or equitable action to disrupt the quiet + enjoyment of the Work by the public as contemplated by Affirmer's express + Statement of Purpose. + + 3. Public License Fallback. Should any part of the Waiver for any reason be + judged legally invalid or ineffective under applicable law, then the Waiver + shall be preserved to the maximum extent permitted taking into account + Affirmer's express Statement of Purpose. In addition, to the extent the + Waiver is so judged Affirmer hereby grants to each affected person a + royalty-free, non transferable, non sublicensable, non exclusive, + irrevocable and unconditional license to exercise Affirmer's Copyright and + Related Rights in the Work (i) in all territories worldwide, (ii) for the + maximum duration provided by applicable law or treaty (including future time + extensions), (iii) in any current or future medium and for any number of + copies, and (iv) for any purpose whatsoever, including without limitation + commercial, advertising or promotional purposes (the "License"). The License + shall be deemed effective as of the date CC0 was applied by Affirmer to the + Work. Should any part of the License for any reason be judged legally + invalid or ineffective under applicable law, such partial invalidity or + ineffectiveness shall not invalidate the remainder of the License, and in + such case Affirmer hereby affirms that he or she will not (i) exercise any + of his or her remaining Copyright and Related Rights in the Work or (ii) + assert any associated claims and causes of action with respect to the Work, + in either case contrary to Affirmer's express Statement of Purpose. + + 4. Limitations and Disclaimers. + + a. No trademark or patent rights held by Affirmer are waived, abandoned, + surrendered, licensed or otherwise affected by this document. + + b. Affirmer offers the Work as-is and makes no representations or + warranties of any kind concerning the Work, express, implied, statutory + or otherwise, including without limitation warranties of title, + merchantability, fitness for a particular purpose, non infringement, or + the absence of latent or other defects, accuracy, or the present or + absence of errors, whether or not discoverable, all to the greatest + extent permissible under applicable law. + + c. Affirmer disclaims responsibility for clearing rights of other persons + that may apply to the Work or any use thereof, including without + limitation any person's Copyright and Related Rights in the Work. + Further, Affirmer disclaims responsibility for obtaining any necessary + consents, permissions or other rights required for any use of the Work. + + d. Affirmer understands and acknowledges that Creative Commons is not a + party to this document and has no duty or obligation with respect to this + CC0 or use of the Work. + +------ + +** Potrace; version 1.16 -- http://potrace.sourceforge.net/ +Copyright (C) 2001-2019 Peter Selinger. + +GNU GENERAL PUBLIC LICENSE + +Version 2, June 1991 + +Copyright (C) 1989, 1991 Free Software Foundation, Inc. + +51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 , USA + +Everyone is permitted to copy and distribute verbatim copies of this license +document, but changing it is not allowed. + +Preamble + +The licenses for most software are designed to take away your freedom to share +and change it. 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. + +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. + +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. + +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. + +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. + +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. + +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. + +The precise terms and conditions for copying, distribution and modification +follow. + +TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 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". + + 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. + + 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. + + 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. + + 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: + + a) You must cause the modified files to carry prominent notices stating + that you changed the files and the date of any change. + + 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. + + 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.) + + 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. + + 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. + + 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. + + 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: + + 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, + + 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, + + 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.) + + 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. + + 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. + + 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. + + 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. + + 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. + + 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. + + 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. + + 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. + + This section is intended to make thoroughly clear what is believed to be a + consequence of the rest of this License. + + 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. + + 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. + + 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. + + 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. + + NO WARRANTY + + 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. + + 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. END OF TERMS AND CONDITIONS + +How to Apply These Terms to Your New Programs + +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. + +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. + +<one line to give the program's name and an idea of what it does.> + +Copyright (C) <yyyy> <name of author> + +This program is free software; you can redistribute it and/or modify it under +the terms of the GNU General Public License as published by the Free Software +Foundation; either version 2 of the License, or (at your option) any later +version. + +This program is distributed in the hope that it will be useful, but WITHOUT ANY +WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A +PARTICULAR PURPOSE. See the GNU General Public License for more details. + +You should have received a copy of the GNU General Public License along with +this program; if not, write to the Free Software Foundation, Inc., 51 Franklin +Street, Fifth Floor, Boston, MA 02110-1301 , USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this when it +starts in an interactive mode: + +Gnomovision version 69, Copyright (C) year name of author Gnomovision comes +with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, +and you are welcome to redistribute it under certain conditions; type `show c' +for details. + +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. + +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.

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. + +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. + +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. + +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. + +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. + +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. + +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. + +The precise terms and conditions for copying, distribution and modification +follow. + +TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 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". + + 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. + + 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. + + 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. + + 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: + + a) You must cause the modified files to carry prominent notices stating + that you changed the files and the date of any change. + + 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. + + 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.) + + 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. + + 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. + + 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. + + 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: + + 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, + + 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, + + 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.) + + 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. + + 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. + + 4.

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. + + 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. + + 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. + + 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. + + 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. + + 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. + + 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. + + 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. + + This section is intended to make thoroughly clear what is believed to be a + consequence of the rest of this License. + + 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. + + 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. + + 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. + + 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. + + NO WARRANTY + + 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. + + 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. END OF TERMS AND CONDITIONS + +How to Apply These Terms to Your New Programs + +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. + +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. + +<one line to give the program's name and an idea of what it does.> + +Copyright (C) <yyyy> <name of author> + +This program is free software; you can redistribute it and/or modify it under +the terms of the GNU General Public License as published by the Free Software +Foundation; either version 2 of the License, or (at your option) any later +version. + +This program is distributed in the hope that it will be useful, but WITHOUT ANY +WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A +PARTICULAR PURPOSE. See the GNU General Public License for more details. + +You should have received a copy of the GNU General Public License along with +this program; if not, write to the Free Software Foundation, Inc., 51 Franklin +Street, Fifth Floor, Boston, MA 02110-1301 , USA. + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this when it +starts in an interactive mode: + +Gnomovision version 69, Copyright (C) year name of author Gnomovision comes +with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, +and you are welcome to redistribute it under certain conditions; type `show c' +for details. + +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. + +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.

By contrast, the GNU General +Public License is intended to guarantee your freedom to share and change all +versions of a program--to make sure it remains free software for all its users. +We, the Free Software Foundation, use the GNU General Public License for most +of our software; it applies also to any other work released this way by its +authors. You can apply it to your programs, too. + +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 them 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. + +To protect your rights, we need to prevent others from denying you these rights +or asking you to surrender the rights. Therefore, you have certain +responsibilities if you distribute copies of the software, or if you modify it: +responsibilities to respect the freedom of others. + +For example, if you distribute copies of such a program, whether gratis or for +a fee, you must pass on to the recipients the same freedoms that you received. +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. + +Developers that use the GNU GPL protect your rights with two steps: (1) assert +copyright on the software, and (2) offer you this License giving you legal +permission to copy, distribute and/or modify it. + +For the developers' and authors' protection, the GPL clearly explains that +there is no warranty for this free software. For both users' and authors' sake, +the GPL requires that modified versions be marked as changed, so that their +problems will not be attributed erroneously to authors of previous versions. + +Some devices are designed to deny users access to install or run modified +versions of the software inside them, although the manufacturer can do so. This +is fundamentally incompatible with the aim of protecting users' freedom to +change the software. The systematic pattern of such abuse occurs in the area of +products for individuals to use, which is precisely where it is most +unacceptable. Therefore, we have designed this version of the GPL to prohibit +the practice for those products. If such problems arise substantially in other +domains, we stand ready to extend this provision to those domains in future +versions of the GPL, as needed to protect the freedom of users. + +Finally, every program is threatened constantly by software patents. States +should not allow patents to restrict development and use of software on +general-purpose computers, but in those that do, we wish to avoid the special +danger that patents applied to a free program could make it effectively +proprietary. To prevent this, the GPL assures that patents cannot be used to +render the program non-free. + +The precise terms and conditions for copying, distribution and modification +follow. + +TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of + works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this License. + Each licensee is addressed as "you". "Licensees" and "recipients" may be + individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work in a + fashion requiring copyright permission, other than the making of an exact + copy. The resulting work is called a "modified version" of the earlier work + or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based on the + Program. + + To "propagate" a work means to do anything with it that, without permission, + would make you directly or secondarily liable for infringement under + applicable copyright law, except executing it on a computer or modifying a + private copy. Propagation includes copying, distribution (with or without + modification), making available to the public, and in some countries other + activities as well. + + To "convey" a work means any kind of propagation that enables other parties + to make or receive copies. Mere interaction with a user through a computer + network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" to the + extent that it includes a convenient and prominently visible feature that + (1) displays an appropriate copyright notice, and (2) tells the user that + there is no warranty for the work (except to the extent that warranties are + provided), that licensees may convey the work under this License, and how to + view a copy of this License. If the interface presents a list of user + commands or options, such as a menu, a prominent item in the list meets this + criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work for making + modifications to it. "Object code" means any non-source form of a work. + + A "Standard Interface" means an interface that either is an official + standard defined by a recognized standards body, or, in the case of + interfaces specified for a particular programming language, one that is + widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other than + the work as a whole, that (a) is included in the normal form of packaging a + Major Component, but which is not part of that Major Component, and (b) + serves only to enable use of the work with that Major Component, or to + implement a Standard Interface for which an implementation is available to + the public in source code form. A "Major Component", in this context, means + a major essential component (kernel, window system, and so on) of the + specific operating system (if any) on which the executable work runs, or a + compiler used to produce the work, or an object code interpreter used to run + it. + + The "Corresponding Source" for a work in object code form means all the + source code needed to generate, install, and (for an executable work) run + the object code and to modify the work, including scripts to control those + activities. However, it does not include the work's System Libraries, or + general-purpose tools or generally available free programs which are used + unmodified in performing those activities but which are not part of the + work. For example, Corresponding Source includes interface definition files + associated with source files for the work, and the source code for shared + libraries and dynamically linked subprograms that the work is specifically + designed to require, such as by intimate data communication or control flow + between those subprograms and other parts of the work. + + The Corresponding Source need not include anything that users can regenerate + automatically from other parts of the Corresponding Source. + + The Corresponding Source for a work in source code form is that same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of copyright + on the Program, and are irrevocable provided the stated conditions are met. + This License explicitly affirms your unlimited permission to run the + unmodified Program. The output from running a covered work is covered by + this License only if the output, given its content, constitutes a covered + work. This License acknowledges your rights of fair use or other equivalent, + as provided by copyright law. + + You may make, run and propagate covered works that you do not convey, + without conditions so long as your license otherwise remains in force. You + may convey covered works to others for the sole purpose of having them make + modifications exclusively for you, or provide you with facilities for + running those works, provided that you comply with the terms of this License + in conveying all material for which you do not control copyright. Those thus + making or running the covered works for you must do so exclusively on your + behalf, under your direction and control, on terms that prohibit them from + making any copies of your copyrighted material outside their relationship + with you. + + Conveying under any other circumstances is permitted solely under the + conditions stated below. Sublicensing is not allowed; section 10 makes it + unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological measure + under any applicable law fulfilling obligations under article 11 of the WIPO + copyright treaty adopted on 20 December 1996, or similar laws prohibiting or + restricting circumvention of such measures. + + When you convey a covered work, you waive any legal power to forbid + circumvention of technological measures to the extent such circumvention is + effected by exercising rights under this License with respect to the covered + work, and you disclaim any intention to limit operation or modification of + the work as a means of enforcing, against the work's users, your or third + parties' legal rights to forbid circumvention of technological measures. + + 4. Conveying Verbatim Copies. + + You may convey 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; keep intact all notices + stating that this License and any non-permissive terms added in accord with + section 7 apply to the code; keep intact all notices of the absence of any + warranty; and give all recipients a copy of this License along with the + Program. + + You may charge any price or no price for each copy that you convey, and you + may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to produce + it from the Program, in the form of source code under the terms of section + 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified it, + and giving a relevant date. + + b) The work must carry prominent notices stating that it is released + under this License and any conditions added under section 7. This + requirement modifies the requirement in section 4 to "keep intact all + notices". + + c) You must license the entire work, as a whole, under this License to + anyone who comes into possession of a copy. This License will therefore + apply, along with any applicable section 7 additional terms, to the whole + of the work, and all its parts, regardless of how they are packaged. This + License gives no permission to license the work in any other way, but it + does not invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your work need + not make them do so. + + A compilation of a covered work with other separate and independent works, + which are not by their nature extensions of the covered work, and which are + not combined with it such as to form a larger program, in or on a volume of + a storage or distribution medium, is called an "aggregate" if the + compilation and its resulting copyright are not used to limit the access or + legal rights of the compilation's users beyond what the individual works + permit. Inclusion of a covered work in an aggregate does not cause this + License to apply to the other parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms of + sections 4 and 5, provided that you also convey the machine-readable + Corresponding Source under the terms of this License, in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium customarily used + for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a written + offer, valid for at least three years and valid for as long as you offer + spare parts or customer support for that product model, to give anyone + who possesses the object code either (1) a copy of the Corresponding + Source for all the software in the product that is covered by this + License, on a durable physical medium customarily used for software + interchange, for a price no more than your reasonable cost of physically + performing this conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the written + offer to provide the Corresponding Source. This alternative is allowed + only occasionally and noncommercially, and only if you received the + object code with such an offer, in accord with subsection 6b. + + d) Convey the object code by offering access from a designated place + (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no further + charge. You need not require recipients to copy the Corresponding Source + along with the object code. If the place to copy the object code is a + network server, the Corresponding Source may be on a different server + (operated by you or a third party) that supports equivalent copying + facilities, provided you maintain clear directions next to the object + code saying where to find the Corresponding Source. Regardless of what + server hosts the Corresponding Source, you remain obligated to ensure + that it is available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided you + inform other peers where the object code and Corresponding Source of the + work are being offered to the general public at no charge under + subsection 6d. + + A separable portion of the object code, whose source code is excluded from + the Corresponding Source as a System Library, need not be included in + conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any + tangible personal property which is normally used for personal, family, or + household purposes, or (2) anything designed or sold for incorporation into + a dwelling. In determining whether a product is a consumer product, doubtful + cases shall be resolved in favor of coverage. For a particular product + received by a particular user, "normally used" refers to a typical or common + use of that class of product, regardless of the status of the particular + user or of the way in which the particular user actually uses, or expects or + is expected to use, the product. A product is a consumer product regardless + of whether the product has substantial commercial, industrial or + non-consumer uses, unless such uses represent the only significant mode of + use of the product. + + "Installation Information" for a User Product means any methods, procedures, + authorization keys, or other information required to install and execute + modified versions of a covered work in that User Product from a modified + version of its Corresponding Source. The information must suffice to ensure + that the continued functioning of the modified object code is in no case + prevented or interfered with solely because modification has been made. + + If you convey an object code work under this section in, or with, or + specifically for use in, a User Product, and the conveying occurs as part of + a transaction in which the right of possession and use of the User Product + is transferred to the recipient in perpetuity or for a fixed term + (regardless of how the transaction is characterized), the Corresponding + Source conveyed under this section must be accompanied by the Installation + Information. But this requirement does not apply if neither you nor any + third party retains the ability to install modified object code on the User + Product (for example, the work has been installed in ROM). + + The requirement to provide Installation Information does not include a + requirement to continue to provide support service, warranty, or updates for + a work that has been modified or installed by the recipient, or for the User + Product in which it has been modified or installed. Access to a network may + be denied when the modification itself materially and adversely affects the + operation of the network or violates the rules and protocols for + communication across the network. + + Corresponding Source conveyed, and Installation Information provided, in + accord with this section must be in a format that is publicly documented + (and with an implementation available to the public in source code form), + and must require no special password or key for unpacking, reading or + copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this License + by making exceptions from one or more of its conditions. Additional + permissions that are applicable to the entire Program shall be treated as + though they were included in this License, to the extent that they are valid + under applicable law. If additional permissions apply only to part of the + Program, that part may be used separately under those permissions, but the + entire Program remains governed by this License without regard to the + additional permissions. + + When you convey a copy of a covered work, you may at your option remove any + additional permissions from that copy, or from any part of it. (Additional + permissions may be written to require their own removal in certain cases + when you modify the work.) You may place additional permissions on material, + added by you to a covered work, for which you have or can give appropriate + copyright permission. + + Notwithstanding any other provision of this License, for material you add to + a covered work, you may (if authorized by the copyright holders of that + material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the terms + of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or author + attributions in that material or in the Appropriate Legal Notices + displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in reasonable + ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some trade + names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that material by + anyone who conveys the material (or modified versions of it) with + contractual assumptions of liability to the recipient, for any liability + that these contractual assumptions directly impose on those licensors and + authors. + + All other non-permissive additional terms are considered "further + restrictions" within the meaning of section 10. If the Program as you + received it, or any part of it, contains a notice stating that it is + governed by this License along with a term that is a further restriction, + you may remove that term. If a license document contains a further + restriction but permits relicensing or conveying under this License, you may + add to a covered work material governed by the terms of that license + document, provided that the further restriction does not survive such + relicensing or conveying. + + If you add terms to a covered work in accord with this section, you must + place, in the relevant source files, a statement of the additional terms + that apply to those files, or a notice indicating where to find the + applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the form of + a separately written license, or stated as exceptions; the above + requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly provided + under this License. Any attempt otherwise to propagate or modify it is void, + and will automatically terminate your rights under this License (including + any patent licenses granted under the third paragraph of section 11). + + However, if you cease all violation of this License, then your license from + a particular copyright holder is reinstated (a) provisionally, unless and + until the copyright holder explicitly and finally terminates your license, + and (b) permanently, if the copyright holder fails to notify you of the + violation by some reasonable means prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is reinstated + permanently if the copyright holder notifies you of the violation by some + reasonable means, this is the first time you have received notice of + violation of this License (for any work) from that copyright holder, and you + cure the violation prior to 30 days after your receipt of the notice. + + Termination of your rights under this section does not terminate the + licenses of parties who have received copies or rights from you under this + License. If your rights have been terminated and not permanently reinstated, + you do not qualify to receive new licenses for the same material under + section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or run a + copy of the Program. Ancillary propagation of a covered work occurring + solely as a consequence of using peer-to-peer transmission to receive a copy + likewise does not require acceptance. However, nothing other than this + License grants you permission to propagate or modify any covered work. These + actions infringe copyright if you do not accept this License. Therefore, by + modifying or propagating a covered work, you indicate your acceptance of + this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically receives a + license from the original licensors, to run, modify and propagate that work, + subject to this License. You are not responsible for enforcing compliance by + third parties with this License. + + An "entity transaction" is a transaction transferring control of an + organization, or substantially all assets of one, or subdividing an + organization, or merging organizations. If propagation of a covered work + results from an entity transaction, each party to that transaction who + receives a copy of the work also receives whatever licenses to the work the + party's predecessor in interest had or could give under the previous + paragraph, plus a right to possession of the Corresponding Source of the + work from the predecessor in interest, if the predecessor has it or can get + it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the rights + granted or affirmed under this License. For example, you may not impose a + license fee, royalty, or other charge for exercise of rights granted under + this License, and you may not initiate litigation (including a cross-claim + or counterclaim in a lawsuit) alleging that any patent claim is infringed by + making, using, selling, offering for sale, or importing the Program or any + portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this License + of the Program or a work on which the Program is based. The work thus + licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims owned or + controlled by the contributor, whether already acquired or hereafter + acquired, that would be infringed by some manner, permitted by this License, + of making, using, or selling its contributor version, but do not include + claims that would be infringed only as a consequence of further modification + of the contributor version. For purposes of this definition, "control" + includes the right to grant patent sublicenses in a manner consistent with + the requirements of this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free patent + license under the contributor's essential patent claims, to make, use, sell, + offer for sale, import and otherwise run, modify and propagate the contents + of its contributor version. + + In the following three paragraphs, a "patent license" is any express + agreement or commitment, however denominated, not to enforce a patent (such + as an express permission to practice a patent or covenant not to sue for + patent infringement). To "grant" such a patent license to a party means to + make such an agreement or commitment not to enforce a patent against the + party. + + If you convey a covered work, knowingly relying on a patent license, and the + Corresponding Source of the work is not available for anyone to copy, free + of charge and under the terms of this License, through a publicly available + network server or other readily accessible means, then you must either (1) + cause the Corresponding Source to be so available, or (2) arrange to deprive + yourself of the benefit of the patent license for this particular work, or + (3) arrange, in a manner consistent with the requirements of this License, + to extend the patent license to downstream recipients. "Knowingly relying" + means you have actual knowledge that, but for the patent license, your + conveying the covered work in a country, or your recipient's use of the + covered work in a country, would infringe one or more identifiable patents + in that country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or arrangement, + you convey, or propagate by procuring conveyance of, a covered work, and + grant a patent license to some of the parties receiving the covered work + authorizing them to use, propagate, modify or convey a specific copy of the + covered work, then the patent license you grant is automatically extended to + all recipients of the covered work and works based on it. + + A patent license is "discriminatory" if it does not include within the scope + of its coverage, prohibits the exercise of, or is conditioned on the + non-exercise of one or more of the rights that are specifically granted + under this License. You may not convey a covered work if you are a party to + an arrangement with a third party that is in the business of distributing + software, under which you make payment to the third party based on the + extent of your activity of conveying the work, and under which the third + party grants, to any of the parties who would receive the covered work from + you, a discriminatory patent license (a) in connection with copies of the + covered work conveyed by you (or copies made from those copies), or (b) + primarily for and in connection with specific products or compilations that + contain the covered work, unless you entered into that arrangement, or that + patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting any + implied license or other defenses to infringement that may otherwise be + available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If 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 convey a + covered work so as to satisfy simultaneously your obligations under this + License and any other pertinent obligations, then as a consequence you may + not convey it at all. For example, if you agree to terms that obligate you + to collect a royalty for further conveying from those to whom you convey the + Program, the only way you could satisfy both those terms and this License + would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have permission to + link or combine any covered work with a work licensed under version 3 of the + GNU Affero General Public License into a single combined work, and to convey + the resulting work. The terms of this License will continue to apply to the + part which is the covered work, but the special requirements of the GNU + Affero General Public License, section 13, concerning interaction through a + network will apply to the combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of the + GNU 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. + + Each version is given a distinguishing version number. If the Program + specifies that a certain numbered version of the GNU General Public License + "or any later version" applies to it, you have the option of following the + terms and conditions either of that numbered version or of any later version + published by the Free Software Foundation. If the Program does not specify a + version number of the GNU General Public License, you may choose any version + ever published by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future versions of + the GNU General Public License can be used, that proxy's public statement of + acceptance of a version permanently authorizes you to choose that version + for the Program. + + Later license versions may give you additional or different permissions. + However, no additional obligations are imposed on any author or copyright + holder as a result of your choosing to follow a later version. + + 15. Disclaimer of Warranty. + + 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. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL + ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS 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. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided above + cannot be given local legal effect according to their terms, reviewing + courts shall apply local law that most closely approximates an absolute + waiver of all civil liability in connection with the Program, unless a + warranty or assumption of liability accompanies a copy of the Program in + return for a fee. END OF TERMS AND CONDITIONS + +How to Apply These Terms to Your New Programs + +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. + +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 state the exclusion +of warranty; and each file should have at least the "copyright" line and a +pointer to where the full notice is found. + +<one line to give the program's name and a brief idea of what it does.> + +Copyright (C) <year> <name of author> + +This program is free software: you can redistribute it and/or modify it under +the terms of the GNU General Public License as published by the Free Software +Foundation, either version 3 of the License, or (at your option) any later +version. + +This program is distributed in the hope that it will be useful, but WITHOUT ANY +WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A +PARTICULAR PURPOSE. See the GNU General Public License for more details. + +You should have received a copy of the GNU General Public License along with +this program. If not, see <http s ://www.gnu.org/licenses/>. + +Also add information on how to contact you by electronic and paper mail. + +If the program does terminal interaction, make it output a short notice like +this when it starts in an interactive mode: + +<program> Copyright (C) <year> <name of author> + +This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + +This is free software, and you are welcome to redistribute it under certain +conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands might +be different; for a GUI interface, you would use an "about box". + +You should also get your employer (if you work as a programmer) or school, if +any, to sign a "copyright disclaimer" for the program, if necessary. For more +information on this, and how to apply and follow the GNU GPL, see <http s +://www.gnu.org/licenses/>. + +The GNU 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. But first, please read <http s ://www.gnu.org/ licenses +/why-not-lgpl.html>. + +------ + +** FFmpeg; version 4.2.3 -- http://ffmpeg.org/ +- + +GNU LESSER GENERAL PUBLIC LICENSE + +Version 2.1, February 1999 + +Copyright (C) 1991, 1999 Free Software Foundation, Inc. + +51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA + +Everyone is permitted to copy and distribute verbatim copies of this license +document, but changing it is not allowed. + +[This is the first released version of the Lesser GPL. It also counts as the +successor of the GNU Library Public License, version 2, hence the version +number 2.1.] + +Preamble + +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. + +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. + +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. + +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. + +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. + +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. + +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. + +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. + +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. + +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. + +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. + +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. + +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. + +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. + +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. + +TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 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". + + 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. + + 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".) + + "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. + + 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. + + 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. + + 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. + + 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: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices stating + that you changed the files and the date of any change. + + 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. + + 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. + + (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.) + + 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. + + 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. + + 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. + + 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. + + 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. + + This option is useful when you wish to copy part of the code of the Library + into a program that is not a library. + + 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. + + 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. + + 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. + + 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. + + 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. + + 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.) + + 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. + + 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. + + 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: + + 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.) + + 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. + + 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. + + 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. + + e) Verify that the user has already received a copy of these materials or + that you have already sent this user a copy. + + 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. + + 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. + + 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: + + 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. + + 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. + + 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. + + 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. + + 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. + + 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. + + 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. + + 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. + + This section is intended to make thoroughly clear what is believed to be a + consequence of the rest of this License. + + 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. + + 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. + + 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. + + 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. + + NO WARRANTY + + 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. + + 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. END OF TERMS AND CONDITIONS + +How to Apply These Terms to Your New Libraries + +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). + +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. + +<one line to give the library's name and an idea of what it does.> + +Copyright (C) <year> <name of author> + +This library is free software; you can redistribute it and/or modify it under +the terms of the GNU Lesser General Public License as published by the Free +Software Foundation; either version 2.1 of the License, or (at your option) any +later version. + +This library is distributed in the hope that it will be useful, but WITHOUT ANY +WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A +PARTICULAR PURPOSE.

Additional Definitions. + + As used herein, "this License" refers to version 3 of the GNU Lesser + General Public License, and the "GNU GPL" refers to version 3 of the GNU + General Public License. + + "The Library" refers to a covered work governed by this License, other + than an Application or a Combined Work as defined below. + + An "Application" is any work that makes use of an interface provided by + the Library, but which is not otherwise based on the Library. Defining a + subclass of a class defined by the Library is deemed a mode of using an + interface provided by the Library. + + A "Combined Work" is a work produced by combining or linking an + Application with the Library. The particular version of the Library with + which the Combined Work was made is also called the "Linked Version". + + The "Minimal Corresponding Source" for a Combined Work means the + Corresponding Source for the Combined Work, excluding any source code for + portions of the Combined Work that, considered in isolation, are based on + the Application, and not on the Linked Version. + + The "Corresponding Application Code" for a Combined Work means the object + code and/or source code for the Application, including any data and + utility programs needed for reproducing the Combined Work from the + Application, but excluding the System Libraries of the Combined Work. + + 1. Exception to Section 3 of the GNU GPL. + + You may convey a covered work under sections 3 and 4 of this License without + being bound by section 3 of the GNU GPL. + + 2. Conveying Modified Versions. + + If you modify a copy of the Library, and, in your modifications, a facility + refers to a function or data to be supplied by an Application that uses the + facility (other than as an argument passed when the facility is invoked), + then you may convey a copy of the modified version: + + a) under this License, provided that you make a good faith effort to + ensure that, in the event an Application does not supply the function or + data, the facility still operates, and performs whatever part of its + purpose remains meaningful, or + + b) under the GNU GPL, with none of the additional permissions of this + License applicable to that copy. + + 3. Object Code Incorporating Material from Library Header Files. + + The object code form of an Application may incorporate material from a + header file that is part of the Library. You may convey such object code + under terms of your choice, provided that, if the incorporated material is + not limited to numerical parameters, data structure layouts and accessors, + or small macros, inline functions and templates (ten or fewer lines in + length), you do both of the following: + + a) Give prominent notice with each copy of the object code that the + Library is used in it and that the Library and its use are covered by + this License. + + b) Accompany the object code with a copy of the GNU GPL and this license + document. + + 4. Combined Works. + + You may convey a Combined Work under terms of your choice that, taken + together, effectively do not restrict modification of the portions of the + Library contained in the Combined Work and reverse engineering for debugging + such modifications, if you also do each of the following: + + a) Give prominent notice with each copy of the Combined Work that the + Library is used in it and that the Library and its use are covered by + this License. + + b) Accompany the Combined Work with a copy of the GNU GPL and this + license document. + + c) For a Combined Work that displays copyright notices during execution, + include the copyright notice for the Library among these notices, as well + as a reference directing the user to the copies of the GNU GPL and this + license document. + + d) Do one of the following: + + 0) Convey the Minimal Corresponding Source under the terms of this + License, and the Corresponding Application Code in a form suitable + for, and under terms that permit, the user to recombine or relink the + Application with a modified version of the Linked Version to produce a + modified Combined Work, in the manner specified by section 6 of the + GNU GPL for conveying Corresponding Source. + + 1) Use a suitable shared library mechanism for linking with the + Library. A suitable mechanism is one that (a) uses at run time a copy + of the Library already present on the user's computer system, and (b) + will operate properly with a modified version of the Library that is + interface-compatible with the Linked Version. + + e) Provide Installation Information, but only if you would otherwise be + required to provide such information under section 6 of the GNU GPL, and + only to the extent that such information is necessary to install and + execute a modified version of the Combined Work produced by recombining + or relinking the Application with a modified version of the Linked + Version. (If you use option 4d0, the Installation Information must + accompany the Minimal Corresponding Source and Corresponding Application + Code. If you use option 4d1, you must provide the Installation + Information in the manner specified by section 6 of the GNU GPL for + conveying Corresponding Source.) + + 5. Combined Libraries. + + 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 that are + not Applications and are not covered by this License, and convey such a + combined library under terms of your choice, if you do both of the + following: + + a) Accompany the combined library with a copy of the same work based on + the Library, uncombined with any other library facilities, conveyed under + the terms of this License. + + b) Give prominent notice with the combined library that part of it is a + work based on the Library, and explaining where to find the accompanying + uncombined form of the same work. + + 6. Revised Versions of the GNU Lesser General Public License. + + The Free Software Foundation may publish revised and/or new versions of the + GNU 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. + + Each version is given a distinguishing version number. If the Library as you + received it specifies that a certain numbered version of the GNU Lesser + General Public License "or any later version" applies to it, you have the + option of following the terms and conditions either of that published + version or of any later version published by the Free Software Foundation. + If the Library as you received it does not specify a version number of the + GNU Lesser General Public License, you may choose any version of the GNU + Lesser General Public License ever published by the Free Software + Foundation. + + If the Library as you received it specifies that a proxy can decide whether + future versions of the GNU Lesser General Public License shall apply, that + proxy's public statement of acceptance of any version is permanent + authorization for you to choose that version for the Library. + +------ + +** LIBPNG; version 1.6.37 -- http://prdownloads.sourceforge.net/libpng +* Copyright (c) 1995-2019 The PNG Reference Library Authors. + * Copyright (c) 2018-2019 Cosmin Truta. + * Copyright (c) 2000-2002, 2004, 2006-2018 Glenn Randers-Pehrson. + * Copyright (c) 1996-1997 Andreas Dilger. + * Copyright (c) 1995-1996 Guy Eric Schalnat, Group 42, Inc. + +This copy of the libpng notices is provided for your convenience.

Distribution of Source Form + + All distribution of Covered Software in Source Code Form, including any + Modifications that You create or to which You contribute, must be under + the terms of this License. You must inform recipients that the Source + Code Form of the Covered Software is governed by the terms of this + License, and how they can obtain a copy of this License. You may not + attempt to alter or restrict the recipients' rights in the Source Code + Form. + + 3.2. Distribution of Executable Form + + If You distribute Covered Software in Executable Form then: + + (a) such Covered Software must also be made available in Source Code + Form, as described in Section 3.1, and You must inform recipients of + the Executable Form how they can obtain a copy of such Source Code + Form by reasonable means in a timely manner, at a charge no more than + the cost of distribution to the recipient; and + + (b) You may distribute such Executable Form under the terms of this + License, or sublicense it under different terms, provided that the + license for the Executable Form does not attempt to limit or alter the + recipients' rights in the Source Code Form under this License. + + 3.3. Distribution of a Larger Work + + You may create and distribute a Larger Work under terms of Your choice, + provided that You also comply with the requirements of this License for + the Covered Software. If the Larger Work is a combination of Covered + Software with a work governed by one or more Secondary Licenses, and the + Covered Software is not Incompatible With Secondary Licenses, this + License permits You to additionally distribute such Covered Software + under the terms of such Secondary License(s), so that the recipient of + the Larger Work may, at their option, further distribute the Covered + Software under the terms of either this License or such Secondary + License(s). + + 3.4.

Application of Additional Terms + + You may choose to offer, and to charge a fee for, warranty, support, + indemnity or liability obligations to one or more recipients of Covered + Software. However, You may do so only on Your own behalf, and not on + behalf of any Contributor. You must make it absolutely clear that any + such warranty, support, indemnity, or liability obligation is offered by + You alone, and You hereby agree to indemnify every Contributor for any + liability incurred by such Contributor as a result of warranty, support, + indemnity or liability terms You offer. You may include additional + disclaimers of warranty and limitations of liability specific to any + jurisdiction. + + 4. Inability to Comply Due to Statute or Regulation + + If it is impossible for You to comply with any of the terms of this License + with respect to some or all of the Covered Software due to statute, judicial + order, or regulation then You must: (a) comply with the terms of this + License to the maximum extent possible; and (b) describe the limitations and + the code they affect. Such description must be placed in a text file + included with all distributions of the Covered Software under this License. + Except to the extent prohibited by statute or regulation, such description + must be sufficiently detailed for a recipient of ordinary skill to be able + to understand it. + + 5. Termination + + 5.1. The rights granted under this License will terminate automatically + if You fail to comply with any of its terms. However, if You become + compliant, then the rights granted under this License from a particular + Contributor are reinstated (a) provisionally, unless and until such + Contributor explicitly and finally terminates Your grants, and (b) on an + ongoing basis, if such Contributor fails to notify You of the + non-compliance by some reasonable means prior to 60 days after You have + come back into compliance. Moreover, Your grants from a particular + Contributor are reinstated on an ongoing basis if such Contributor + notifies You of the non-compliance by some reasonable means, this is the + first time You have received notice of non-compliance with this License + from such Contributor, and You become compliant prior to 30 days after + Your receipt of the notice. + + 5.2. If You initiate litigation against any entity by asserting a patent + infringement claim (excluding declaratory judgment actions, + counter-claims, and cross-claims) alleging that a Contributor Version + directly or indirectly infringes any patent, then the rights granted to + You by any and all Contributors for the Covered Software under Section + 2.1 of this License shall terminate. + + 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end + user license agreements (excluding distributors and resellers) which have + been validly granted by You or Your distributors under this License prior + to termination shall survive termination. + + 6. Disclaimer of Warranty + + Covered Software is provided under this License on an "as is" basis, without + warranty of any kind, either expressed, implied, or statutory, including, + without limitation, warranties that the Covered Software is free of defects, + merchantable, fit for a particular purpose or non-infringing. The entire + risk as to the quality and performance of the Covered Software is with You. + Should any Covered Software prove defective in any respect, You (not any + Contributor) assume the cost of any necessary servicing, repair, or + correction. This disclaimer of warranty constitutes an essential part of + this License. No use of any Covered Software is authorized under this + License except under this disclaimer. + + 7. Limitation of Liability + + Under no circumstances and under no legal theory, whether tort (including + negligence), contract, or otherwise, shall any Contributor, or anyone who + distributes Covered Software as permitted above, be liable to You for any + direct, indirect, special, incidental, or consequential damages of any + character including, without limitation, damages for lost profits, loss of + goodwill, work stoppage, computer failure or malfunction, or any and all + other commercial damages or losses, even if such party shall have been + informed of the possibility of such damages. This limitation of liability + shall not apply to liability for death or personal injury resulting from + such party's negligence to the extent applicable law prohibits such + limitation. Some jurisdictions do not allow the exclusion or limitation of + incidental or consequential damages, so this exclusion and limitation may + not apply to You. + + 8. Litigation + + Any litigation relating to this License may be brought only in the courts of + a jurisdiction where the defendant maintains its principal place of business + and such litigation shall be governed by laws of that jurisdiction, without + reference to its conflict-of-law provisions. Nothing in this Section shall + prevent a party's ability to bring cross-claims or counter-claims. + + 9. Miscellaneous + + This License represents the complete agreement concerning the subject matter + hereof. If any provision of this License is held to be unenforceable, such + provision shall be reformed only to the extent necessary to make it + enforceable. Any law or regulation which provides that the language of a + contract shall be construed against the drafter shall not be used to + construe this License against a Contributor. + + 10. Versions of the License + + 10.1. New Versions + + Mozilla Foundation is the license steward. Except as provided in Section + 10.3, no one other than the license steward has the right to modify or + publish new versions of this License. Each version will be given a + distinguishing version number. + + 10.2. Effect of New Versions + + You may distribute the Covered Software under the terms of the version of + the License under which You originally received the Covered Software, or + under the terms of any subsequent version published by the license + steward. + + 10.3. Modified Versions + + If you create software not governed by this License, and you want to + create a new license for such software, you may create and use a modified + version of this License if you rename the license and remove any + references to the name of the license steward (except to note that such + modified license differs from this License). + + 10.4.

All rights reserved. + +A. HISTORY OF THE SOFTWARE +========================== + +Python was created in the early 1990s by Guido van Rossum at Stichting +Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands +as a successor of a language called ABC. Guido remains Python's +principal author, although it includes many contributions from others. + +In 1995, Guido continued his work on Python at the Corporation for +National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) +in Reston, Virginia where he released several versions of the +software. + +In May 2000, Guido and the Python core development team moved to +BeOpen.com to form the BeOpen PythonLabs team. In October of the same +year, the PythonLabs team moved to Digital Creations, which became +Zope Corporation. In 2001, the Python Software Foundation (PSF, see +https://www.python.org/psf/) was formed, a non-profit organization +created specifically to own Python-related Intellectual Property. +Zope Corporation was a sponsoring member of the PSF. + +All Python releases are Open Source (see http://www.opensource.org for +the Open Source Definition). Historically, most, but not all, Python +releases have also been GPL-compatible; the table below summarizes +the various releases. + + Release Derived Year Owner GPL- + from compatible? (1) + + 0.9.0 thru 1.2 1991-1995 CWI yes + 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes + 1.6 1.5.2 2000 CNRI no + 2.0 1.6 2000 BeOpen.com no + 1.6.1 1.6 2001 CNRI yes (2) + 2.1 2.0+1.6.1 2001 PSF no + 2.0.1 2.0+1.6.1 2001 PSF yes + 2.1.1 2.1+2.0.1 2001 PSF yes + 2.1.2 2.1.1 2002 PSF yes + 2.1.3 2.1.2 2002 PSF yes + 2.2 and above 2.1.1 2001-now PSF yes + +Footnotes: + +(1) GPL-compatible doesn't mean that we're distributing Python under + the GPL. All Python licenses, unlike the GPL, let you distribute + a modified version without making your changes open source. The + GPL-compatible licenses make it possible to combine Python with + other software that is released under the GPL; the others don't. + +(2) According to Richard Stallman, 1.6.1 is not GPL-compatible, + because its license has a choice of law clause. According to + CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1 + is "not incompatible" with the GPL. + +Thanks to the many outside volunteers who have worked under Guido's +direction to make these releases possible. + + +B.
