In order to make this project\nusable to a vast majority of developers, we distribute it under two\nmutually exclusive open-source licenses.\n\nThis means that *you* must choose *one* of the two licenses described\nbelow, then obey all its terms and conditions when using FreeType 2 in\nany of your projects or products.\n\n - The FreeType License, found in the file `docs/FTL.TXT`, which is\n similar to the original BSD license *with* an advertising clause\n that forces you to explicitly cite the FreeType project in your\n product's documentation. All details are in the license file.\n This license is suited to products which don't use the GNU General\n Public License.\n\n Note that this license is compatible to the GNU General Public\n License version 3, but not version 2.\n\n - The GNU General Public License version 2, found in\n `docs/GPLv2.TXT` (any later version can be used also), for\n programs which already use the GPL. Note that the FTL is\n incompatible with GPLv2 due to its advertisement clause.\n\nThe contributed BDF and PCF drivers come with a license similar to\nthat of the X Window System. It is compatible to the above two\nlicenses (see files `src/bdf/README` and `src/pcf/README`). The same\nholds for the source code files `src/base/fthash.c` and\n`include/freetype/internal/fthash.h`; they were part of the BDF driver\nin earlier FreeType versions.\n\nThe gzip module uses the zlib license (see `src/gzip/zlib.h`) which\ntoo is compatible to the above two licenses.\n\nThe files `src/autofit/ft-hb.c` and `src/autofit/ft-hb.h` contain code\ntaken almost verbatim from the HarfBuzz file `hb-ft.cc`, which uses\nthe 'Old MIT' license, compatible to the above two licenses.\n\nThe MD5 checksum support (only used for debugging in development\nbuilds) is in the public domain.\n\n\n--- end of LICENSE.TXT ---\n The FreeType Project LICENSE\n ----------------------------\n\n 2006-Jan-27\n\n Copyright 1996-2002, 2006 by\n David Turner, Robert Wilhelm, and Werner Lemberg\n\n\n\nIntroduction\n============\n\n The FreeType Project is distributed in several archive packages;\n some of them may contain, in addition to the FreeType font engine,\n various tools and contributions which rely on, or relate to, the\n FreeType Project.\n\n This license applies to all files found in such packages, and\n which do not fall under their own explicit license. The license\n affects thus the FreeType font engine, the test programs,\n documentation and makefiles, at the very least.\n\n This license was inspired by the BSD, Artistic, and IJG\n (Independent JPEG Group) licenses, which all encourage inclusion\n and use of free software in commercial and freeware products\n alike. As a consequence, its main points are that:\n\n o We don't promise that this software works. However, we will be\n interested in any kind of bug reports. (`as is' distribution)\n\n o You can use this software for whatever you want, in parts or\n full form, without having to pay us. (`royalty-free' usage)\n\n o You may not pretend that you wrote this software. If you use\n it, or only parts of it, in a program, you must acknowledge\n somewhere in your documentation that you have used the\n FreeType code. (`credits')\n\n We specifically permit and encourage the inclusion of this\n software, with or without modifications, in commercial products.\n We disclaim all warranties covering The FreeType Project and\n assume no liability related to The FreeType Project.\n\n\n Finally, many people asked us for a preferred form for a\n credit/disclaimer to use in compliance with this license. We thus\n encourage you to use the following text:\n\n """\n Portions of this software are copyright © <year> The FreeType\n Project (www.freetype.org). All rights reserved.\n """\n\n Please replace <year> with the value from the FreeType version you\n actually use.\n\n\nLegal Terms\n===========\n\n0. Definitions\n--------------\n\n Throughout this license, the terms `package', `FreeType Project',\n and `FreeType archive' refer to the set of files originally\n distributed by the authors (David Turner, Robert Wilhelm, and\n Werner Lemberg) as the `FreeType Project', be they named as alpha,\n beta or final release.\n\n `You' refers to the licensee, or person using the project, where\n `using' is a generic term including compiling the project's source\n code as well as linking it to form a `program' or `executable'.\n This program is referred to as `a program using the FreeType\n engine'.\n\n This license applies to all files distributed in the original\n FreeType Project, including all source code, binaries and\n documentation, unless otherwise stated in the file in its\n original, unmodified form as distributed in the original archive.\n If you are unsure whether or not a particular file is covered by\n this license, you must contact us to verify this.\n\n The FreeType Project is copyright (C) 1996-2000 by David Turner,\n Robert Wilhelm, and Werner Lemberg.

IN NO EVENT WILL ANY OF THE AUTHORS OR COPYRIGHT HOLDERS\n BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE OR THE INABILITY TO\n USE, OF THE FREETYPE PROJECT.\n\n2.

The copyright notices of the unaltered,\n original files must be preserved in all copies of source\n files.\n\n o Redistribution in binary form must provide a disclaimer that\n states that the software is based in part of the work of the\n FreeType Team, in the distribution documentation. We also\n encourage you to put an URL to the FreeType web page in your\n documentation, though this isn't mandatory.\n\n These conditions apply to any software derived from or based on\n the FreeType Project, not just the unmodified files. If you use\n our work, you must acknowledge us. However, no fee need be paid\n to us.\n\n3.

By contrast, the GNU General Public\nLicense is intended to guarantee your freedom to share and change free\nsoftware--to make sure the software is free for all its users. This\nGeneral Public License applies to most of the Free Software\nFoundation's software and to any other program whose authors commit to\nusing it. (Some other Free Software Foundation software is covered by\nthe GNU Library General Public License instead.) You can apply it to\nyour programs, too.\n\n When we speak of free software, we are referring to freedom, not\nprice. Our General Public Licenses are designed to make sure that you\nhave the freedom to distribute copies of free software (and charge for\nthis service if you wish), that you receive source code or can get it\nif you want it, that you can change the software or use pieces of it\nin new free programs; and that you know you can do these things.\n\n To protect your rights, we need to make restrictions that forbid\nanyone to deny you these rights or to ask you to surrender the rights.\nThese restrictions translate to certain responsibilities for you if you\ndistribute copies of the software, or if you modify it.\n\n For example, if you distribute copies of such a program, whether\ngratis or for a fee, you must give the recipients all the rights that\nyou have. You must make sure that they, too, receive or can get the\nsource code. And you must show them these terms so they know their\nrights.\n\n We protect your rights with two steps: (1) copyright the software, and\n(2) offer you this license which gives you legal permission to copy,\ndistribute and/or modify the software.\n\n Also, for each author's protection and ours, we want to make certain\nthat everyone understands that there is no warranty for this free\nsoftware. If the software is modified by someone else and passed on, we\nwant its recipients to know that what they have is not the original, so\nthat any problems introduced by others will not reflect on the original\nauthors' reputations.\n\n Finally, any free program is threatened constantly by software\npatents. We wish to avoid the danger that redistributors of a free\nprogram will individually obtain patent licenses, in effect making the\nprogram proprietary. To prevent this, we have made it clear that any\npatent must be licensed for everyone's free use or not licensed at all.\n\n The precise terms and conditions for copying, distribution and\nmodification follow.\n \n GNU GENERAL PUBLIC LICENSE\n TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION\n\n 0. This License applies to any program or other work which contains\na notice placed by the copyright holder saying it may be distributed\nunder the terms of this General Public License. The "Program", below,\nrefers to any such program or work, and a "work based on the Program"\nmeans either the Program or any derivative work under copyright law:\nthat is to say, a work containing the Program or a portion of it,\neither verbatim or with modifications and/or translated into another\nlanguage. (Hereinafter, translation is included without limitation in\nthe term "modification".) Each licensee is addressed as "you".\n\nActivities other than copying, distribution and modification are not\ncovered by this License; they are outside its scope. The act of\nrunning the Program is not restricted, and the output from the Program\nis covered only if its contents constitute a work based on the\nProgram (independent of having been made by running the Program).\nWhether that is true depends on what the Program does.\n\n 1. You may copy and distribute verbatim copies of the Program's\nsource code as you receive it, in any medium, provided that you\nconspicuously and appropriately publish on each copy an appropriate\ncopyright notice and disclaimer of warranty; keep intact all the\nnotices that refer to this License and to the absence of any warranty;\nand give any other recipients of the Program a copy of this License\nalong with the Program.\n\nYou may charge a fee for the physical act of transferring a copy, and\nyou may at your option offer warranty protection in exchange for a fee.\n\n 2. You may modify your copy or copies of the Program or any portion\nof it, thus forming a work based on the Program, and copy and\ndistribute such modifications or work under the terms of Section 1\nabove, provided that you also meet all of these conditions:\n\n a) You must cause the modified files to carry prominent notices\n stating that you changed the files and the date of any change.\n\n b) You must cause any work that you distribute or publish, that in\n whole or in part contains or is derived from the Program or any\n part thereof, to be licensed as a whole at no charge to all third\n parties under the terms of this License.\n\n c) If the modified program normally reads commands interactively\n when run, you must cause it, when started running for such\n interactive use in the most ordinary way, to print or display an\n announcement including an appropriate copyright notice and a\n notice that there is no warranty (or else, saying that you provide\n a warranty) and that users may redistribute the program under\n these conditions, and telling the user how to view a copy of this\n License. (Exception: if the Program itself is interactive but\n does not normally print such an announcement, your work based on\n the Program is not required to print an announcement.)\n \nThese requirements apply to the modified work as a whole. If\nidentifiable sections of that work are not derived from the Program,\nand can be reasonably considered independent and separate works in\nthemselves, then this License, and its terms, do not apply to those\nsections when you distribute them as separate works. But when you\ndistribute the same sections as part of a whole which is a work based\non the Program, the distribution of the whole must be on the terms of\nthis License, whose permissions for other licensees extend to the\nentire whole, and thus to each and every part regardless of who wrote it.\n\nThus, it is not the intent of this section to claim rights or contest\nyour rights to work written entirely by you; rather, the intent is to\nexercise the right to control the distribution of derivative or\ncollective works based on the Program.\n\nIn addition, mere aggregation of another work not based on the Program\nwith the Program (or with a work based on the Program) on a volume of\na storage or distribution medium does not bring the other work under\nthe scope of this License.\n\n 3. You may copy and distribute the Program (or a work based on it,\nunder Section 2) in object code or executable form under the terms of\nSections 1 and 2 above provided that you also do one of the following:\n\n a) Accompany it with the complete corresponding machine-readable\n source code, which must be distributed under the terms of Sections\n 1 and 2 above on a medium customarily used for software interchange; or,\n\n b) Accompany it with a written offer, valid for at least three\n years, to give any third party, for a charge no more than your\n cost of physically performing source distribution, a complete\n machine-readable copy of the corresponding source code, to be\n distributed under the terms of Sections 1 and 2 above on a medium\n customarily used for software interchange; or,\n\n c) Accompany it with the information you received as to the offer\n to distribute corresponding source code. (This alternative is\n allowed only for noncommercial distribution and only if you\n received the program in object code or executable form with such\n an offer, in accord with Subsection b above.)\n\nThe source code for a work means the preferred form of the work for\nmaking modifications to it. For an executable work, complete source\ncode means all the source code for all modules it contains, plus any\nassociated interface definition files, plus the scripts used to\ncontrol compilation and installation of the executable. However, as a\nspecial exception, the source code distributed need not include\nanything that is normally distributed (in either source or binary\nform) with the major components (compiler, kernel, and so on) of the\noperating system on which the executable runs, unless that component\nitself accompanies the executable.\n\nIf distribution of executable or object code is made by offering\naccess to copy from a designated place, then offering equivalent\naccess to copy the source code from the same place counts as\ndistribution of the source code, even though third parties are not\ncompelled to copy the source along with the object code.\n \n 4. You may not copy, modify, sublicense, or distribute the Program\nexcept as expressly provided under this License. Any attempt\notherwise to copy, modify, sublicense or distribute the Program is\nvoid, and will automatically terminate your rights under this License.\nHowever, parties who have received copies, or rights, from you under\nthis License will not have their licenses terminated so long as such\nparties remain in full compliance.\n\n 5. You are not required to accept this License, since you have not\nsigned it. However, nothing else grants you permission to modify or\ndistribute the Program or its derivative works. These actions are\nprohibited by law if you do not accept this License. Therefore, by\nmodifying or distributing the Program (or any work based on the\nProgram), you indicate your acceptance of this License to do so, and\nall its terms and conditions for copying, distributing or modifying\nthe Program or works based on it.\n\n 6. Each time you redistribute the Program (or any work based on the\nProgram), the recipient automatically receives a license from the\noriginal licensor to copy, distribute or modify the Program subject to\nthese terms and conditions. You may not impose any further\nrestrictions on the recipients' exercise of the rights granted herein.\nYou are not responsible for enforcing compliance by third parties to\nthis License.\n\n 7. If, as a consequence of a court judgment or allegation of patent\ninfringement or for any other reason (not limited to patent issues),\nconditions are imposed on you (whether by court order, agreement or\notherwise) that contradict the conditions of this License, they do not\nexcuse you from the conditions of this License. If you cannot\ndistribute so as to satisfy simultaneously your obligations under this\nLicense and any other pertinent obligations, then as a consequence you\nmay not distribute the Program at all. For example, if a patent\nlicense would not permit royalty-free redistribution of the Program by\nall those who receive copies directly or indirectly through you, then\nthe only way you could satisfy both it and this License would be to\nrefrain entirely from distribution of the Program.\n\nIf any portion of this section is held invalid or unenforceable under\nany particular circumstance, the balance of the section is intended to\napply and the section as a whole is intended to apply in other\ncircumstances.\n\nIt is not the purpose of this section to induce you to infringe any\npatents or other property right claims or to contest validity of any\nsuch claims; this section has the sole purpose of protecting the\nintegrity of the free software distribution system, which is\nimplemented by public license practices. Many people have made\ngenerous contributions to the wide range of software distributed\nthrough that system in reliance on consistent application of that\nsystem; it is up to the author/donor to decide if he or she is willing\nto distribute software through any other system and a licensee cannot\nimpose that choice.\n\nThis section is intended to make thoroughly clear what is believed to\nbe a consequence of the rest of this License.\n \n 8. If the distribution and/or use of the Program is restricted in\ncertain countries either by patents or by copyrighted interfaces, the\noriginal copyright holder who places the Program under this License\nmay add an explicit geographical distribution limitation excluding\nthose countries, so that distribution is permitted only in or among\ncountries not thus excluded. In such case, this License incorporates\nthe limitation as if written in the body of this License.\n\n 9. The Free Software Foundation may publish revised and/or new versions\nof the General Public License from time to time. Such new versions will\nbe similar in spirit to the present version, but may differ in detail to\naddress new problems or concerns.\n\nEach version is given a distinguishing version number. If the Program\nspecifies a version number of this License which applies to it and "any\nlater version", you have the option of following the terms and conditions\neither of that version or of any later version published by the Free\nSoftware Foundation. If the Program does not specify a version number of\nthis License, you may choose any version ever published by the Free Software\nFoundation.\n\n 10. If you wish to incorporate parts of the Program into other free\nprograms whose distribution conditions are different, write to the author\nto ask for permission. For software which is copyrighted by the Free\nSoftware Foundation, write to the Free Software Foundation; we sometimes\nmake exceptions for this. Our decision will be guided by the two goals\nof preserving the free status of all derivatives of our free software and\nof promoting the sharing and reuse of software generally.\n\n NO WARRANTY\n\n 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY\nFOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN\nOTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES\nPROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED\nOR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF\nMERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS\nTO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE\nPROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,\nREPAIR OR CORRECTION.\n\n 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING\nWILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR\nREDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,\nINCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING\nOUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED\nTO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY\nYOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER\nPROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE\nPOSSIBILITY OF SUCH DAMAGES.\n\n END OF TERMS AND CONDITIONS\n \n How to Apply These Terms to Your New Programs\n\n If you develop a new program, and you want it to be of the greatest\npossible use to the public, the best way to achieve this is to make it\nfree software which everyone can redistribute and change under these terms.\n\n To do so, attach the following notices to the program. It is safest\nto attach them to the start of each source file to most effectively\nconvey the exclusion of warranty; and each file should have at least\nthe "copyright" line and a pointer to where the full notice is found.\n\n <one line to give the program's name and a brief idea of what it does.>\n Copyright (C) <year> <name of author>\n\n This program is free software; you can redistribute it and/or modify\n it under the terms of the GNU General Public License as published by\n the Free Software Foundation; either version 2 of the License, or\n (at your option) any later version.\n\n This program is distributed in the hope that it will be useful,\n but WITHOUT ANY WARRANTY; without even the implied warranty of\n MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the\n GNU General Public License for more details.\n\n You should have received a copy of the GNU General Public License\n along with this program; if not, write to the Free Software\n Foundation, Inc., 51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA\n\n\nAlso add information on how to contact you by electronic and paper mail.\n\nIf the program is interactive, make it output a short notice like this\nwhen it starts in an interactive mode:\n\n Gnomovision version 69, Copyright (C) year name of author\n Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.\n This is free software, and you are welcome to redistribute it\n under certain conditions; type `show c' for details.\n\nThe hypothetical commands `show w' and `show c' should show the appropriate\nparts of the General Public License. Of course, the commands you use may\nbe called something other than `show w' and `show c'; they could even be\nmouse-clicks or menu items--whatever suits your program.\n\nYou should also get your employer (if you work as a programmer) or your\nschool, if any, to sign a "copyright disclaimer" for the program, if\nnecessary. Here is a sample; alter the names:\n\n Yoyodyne, Inc., hereby disclaims all copyright interest in the program\n `Gnomovision' (which makes passes at compilers) written by James Hacker.\n\n <signature of Ty Coon>, 1 April 1989\n Ty Coon, President of Vice\n\nThis General Public License does not permit incorporating your program into\nproprietary programs. If your program is a subroutine library, you may\nconsider it more useful to permit linking proprietary applications with the\nlibrary. If this is what you want to do, use the GNU Library General\nPublic License instead of this License.\n \n===== harfbuzz-11.2.1 ===== \n \nHarfBuzz is licensed under the so-called "Old MIT" license.

We don't promise that this software works. (But if you find any bugs,\n please let us know!)\n2. You can use this software for whatever you want. You don't have to pay us.\n3. You may not pretend that you wrote this software. If you use it in a\n program, you must acknowledge somewhere in your documentation that\n you've used the IJG code.\n\nIn legalese:\n\nThe authors make NO WARRANTY or representation, either express or implied,\nwith respect to this software, its quality, accuracy, merchantability, or\nfitness for a particular purpose. This software is provided "AS IS", and you,\nits user, assume the entire risk as to its quality and accuracy.\n\nThis software is copyright (C) 1991-2020, Thomas G. Lane, Guido Vollbeding.\nAll Rights Reserved except as specified below.\n\nPermission is hereby granted to use, copy, modify, and distribute this\nsoftware (or portions thereof) for any purpose, without fee, subject to these\nconditions:\n(1) If any part of the source code for this software is distributed, then this\nREADME file must be included, with this copyright and no-warranty notice\nunaltered; and any additions, deletions, or changes to the original files\nmust be clearly indicated in accompanying documentation.\n(2) If only executable code is distributed, then the accompanying\ndocumentation must state that "this software is based in part on the work of\nthe Independent JPEG Group".\n(3) Permission for use of this software is granted only if the user accepts\nfull responsibility for any undesirable consequences; the authors accept\nNO LIABILITY for damages of any kind.\n\nThese conditions apply to any software derived from or based on the IJG code,\nnot just to the unmodified library. If you use our work, you ought to\nacknowledge us.\n\nPermission is NOT granted for the use of any IJG author's name or company name\nin advertising or publicity relating to this software or products derived from\nit. This software may be referred to only as "the Independent JPEG Group's\nsoftware".\n\nWe specifically permit and encourage the use of this software as the basis of\ncommercial products, provided that all warranty or liability claims are\nassumed by the product vendor.\n\nlibjpeg-turbo Licenses\n======================\n\nlibjpeg-turbo is covered by two compatible BSD-style open source licenses:\n\n- The IJG (Independent JPEG Group) License, which is listed in\n [README.ijg](README.ijg)\n\n This license applies to the libjpeg API library and associated programs,\n including any code inherited from libjpeg and any modifications to that\n code. Note that the libjpeg-turbo SIMD source code bears the\n [zlib License](https://opensource.org/licenses/Zlib), but in the context of\n the overall libjpeg API library, the terms of the zlib License are subsumed\n by the terms of the IJG License.\n\n- The Modified (3-clause) BSD License, which is listed below\n\n This license applies to the TurboJPEG API library and associated programs, as\n well as the build system. Note that the TurboJPEG API library wraps the\n libjpeg API library, so in the context of the overall TurboJPEG API library,\n both the terms of the IJG License and the terms of the Modified (3-clause)\n BSD License apply.\n\n\nComplying with the libjpeg-turbo Licenses\n=========================================\n\nThis section provides a roll-up of the libjpeg-turbo licensing terms, to the\nbest of our understanding. This is not a license in and of itself. It is\nintended solely for clarification.\n\n1. If you are distributing a modified version of the libjpeg-turbo source,\n then:\n\n 1. You cannot alter or remove any existing copyright or license notices\n from the source.\n\n **Origin**\n - Clause 1 of the IJG License\n - Clause 1 of the Modified BSD License\n - Clauses 1 and 3 of the zlib License\n\n 2. You must add your own copyright notice to the header of each source\n file you modified, so others can tell that you modified that file. (If\n there is not an existing copyright header in that file, then you can\n simply add a notice stating that you modified the file.)\n\n **Origin**\n - Clause 1 of the IJG License\n - Clause 2 of the zlib License\n\n 3. You must include the IJG README file, and you must not alter any of the\n copyright or license text in that file.\n\n **Origin**\n - Clause 1 of the IJG License\n\n2. If you are distributing only libjpeg-turbo binaries without the source, or\n if you are distributing an application that statically links with\n libjpeg-turbo, then:\n\n 1. Your product documentation must include a message stating:\n\n This software is based in part on the work of the Independent JPEG\n Group.\n\n **Origin**\n - Clause 2 of the IJG license\n\n 2. If your binary distribution includes or uses the TurboJPEG API, then\n your product documentation must include the text of the Modified BSD\n License (see below.)\n\n **Origin**\n - Clause 2 of the Modified BSD License\n\n3. You cannot use the name of the IJG or The libjpeg-turbo Project or the\n contributors thereof in advertising, publicity, etc.\n\n **Origin**\n - IJG License\n - Clause 3 of the Modified BSD License\n\n4. The IJG and The libjpeg-turbo Project do not warrant libjpeg-turbo to be\n free of defects, nor do we accept any liability for undesirable\n consequences resulting from your use of the software.\n\n **Origin**\n - IJG License\n - Modified BSD License\n - zlib License\n\n\nThe Modified (3-clause) BSD License\n===================================\n\nCopyright (C)2009-2024 D. R. Commander. All Rights Reserved.<br>\nCopyright (C)2015 Viktor Szathmáry.

However, the IJG\nLicense specifically refers to the Independent JPEG Group and does not extend\nattribution and endorsement protections to other entities. Thus, it was\ndesirable to choose a license that granted us the same protections for new code\nthat were granted to the IJG for code derived from their software.\n \n===== libpng-1.6.49 ===== \n \nCOPYRIGHT NOTICE, DISCLAIMER, and LICENSE\n=========================================\n\nPNG Reference Library License version 2\n---------------------------------------\n\n * Copyright (c) 1995-2025 The PNG Reference Library Authors.\n * Copyright (c) 2018-2025 Cosmin Truta.\n * Copyright (c) 2000-2002, 2004, 2006-2018 Glenn Randers-Pehrson.\n * Copyright (c) 1996-1997 Andreas Dilger.\n * Copyright (c) 1995-1996 Guy Eric Schalnat, Group 42, Inc.\n\nThe software is supplied "as is", without warranty of any kind,\nexpress or implied, including, without limitation, the warranties\nof merchantability, fitness for a particular purpose, title, and\nnon-infringement.

Here\n is a summary of which licenses apply to which parts of this package:\n\n - liblzma is under the BSD Zero Clause License (0BSD).\n\n - The command line tools xz, xzdec, lzmadec, and lzmainfo are\n under 0BSD except that, on systems that don't have a usable\n getopt_long, GNU getopt_long is compiled and linked in from the\n 'lib' directory. The getopt_long code is under GNU LGPLv2.1+.\n\n - The scripts to grep, diff, and view compressed files have been\n adapted from GNU gzip. These scripts (xzgrep, xzdiff, xzless,\n and xzmore) are under GNU GPLv2+. The man pages of the scripts\n are under 0BSD; they aren't based on the man pages of GNU gzip.\n\n - Most of the XZ Utils specific documentation that is in\n plain text files (like README, INSTALL, PACKAGERS, NEWS,\n and ChangeLog) are under 0BSD unless stated otherwise in\n the file itself. The files xz-file-format.txt and\n lzma-file-format.xt are in the public domain but may\n be distributed under the terms of 0BSD too.\n\n - Translated messages and man pages are under 0BSD except that\n some old translations are in the public domain.\n\n - Test files and test code in the 'tests' directory, and\n debugging utilities in the 'debug' directory are under\n the BSD Zero Clause License (0BSD).\n\n - The GNU Autotools based build system contains files that are\n under GNU GPLv2+, GNU GPLv3+, and a few permissive licenses.\n These files don't affect the licensing of the binaries being\n built.\n\n - The 'extra' directory contains files that are under various\n free software licenses. These aren't built or installed as\n part of XZ Utils.\n\n The following command may be helpful in finding per-file license\n information. It works on xz.git and on a clean file tree extracted\n from a release tarball.\n\n sh build-aux/license-check.sh -v\n\n For the files under the BSD Zero Clause License (0BSD), if\n a copyright notice is needed, the following is sufficient:\n\n Copyright (C) The XZ Utils authors and contributors\n\n If you copy significant amounts of 0BSD-licensed code from XZ Utils\n into your project, acknowledging this somewhere in your software is\n polite (especially if it is proprietary, non-free software), but\n it is not legally required by the license terms. Here is an example\n of a good notice to put into "about box" or into documentation:\n\n This software includes code from XZ Utils <https://tukaani.org/xz/>.\n\n The following license texts are included in the following files:\n - COPYING.0BSD: BSD Zero Clause License\n - COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1\n - COPYING.GPLv2: GNU General Public License version 2\n - COPYING.GPLv3: GNU General Public License version 3\n\n If you have questions, don't hesitate to ask for more information.\n The contact information is in the README file.\n\n \n===== zlib-ng-2.2.4 ===== \n \n(C) 1995-2024 Jean-loup Gailly and Mark Adler\n\nThis software is provided 'as-is', without any express or implied\nwarranty.
