Linking a program with a library, without + changing the library, is in some sense simply using the library, and is + analogous to running a utility program or application program. However, in + a textual and legal sense, the linked executable is a combined work, a + derivative of the original library, and the ordinary General Public License + treats it as such. - ==================================================================== + Because of this blurred distinction, using the ordinary General + Public License for libraries did not effectively promote software + sharing, because most developers did not use the libraries.

Pay close attention to the difference between a + "work based on the library" and a "work that uses the library".

Definitions. + 0. This License Agreement applies to any software library which + contains a notice placed by the copyright holder or other authorized + party saying it may be distributed under the terms of this Library + General Public License (also called "this License"). Each licensee is + addressed as "you". - "License" shall mean the terms and conditions for use, reproduction, - and distribution as defined by Sections 1 through 9 of this document. + 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. - "Licensor" shall mean the copyright owner or entity authorized by - the copyright owner that is granting the License. + 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".) - "Legal Entity" shall mean the union of the acting entity and all - other entities that control, are controlled by, or are under common - control with that entity. For the purposes of this definition, - "control" means (i) the power, direct or indirect, to cause the - direction or management of such entity, whether by contract or - otherwise, or (ii) ownership of fifty percent (50%) or more of the - outstanding shares, or (iii) beneficial ownership of such entity. + "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. - "You" (or "Your") shall mean an individual or Legal Entity - exercising permissions granted by this License. + 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. - "Source" form shall mean the preferred form for making modifications, - including but not limited to software source code, documentation - source, and configuration files. + 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: - "Object" form shall mean any form resulting from mechanical - transformation or translation of a Source form, including but - not limited to compiled object code, generated documentation, - and conversions to other media types. + a) The modified work must itself be a software library. - "Work" shall mean the work of authorship, whether in Source or - Object form, made available under the License, as indicated by a - copyright notice that is included in or attached to the work - (an example is provided in the Appendix below). + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. - "Derivative Works" shall mean any work, whether in Source or Object - form, that is based on (or derived from) the Work and for which the - editorial revisions, annotations, elaborations, or other modifications - represent, as a whole, an original work of authorship. For the purposes - of this License, Derivative Works shall not include works that remain - separable from, or merely link (or bind by name) to the interfaces of, - the Work and Derivative Works thereof. + 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. - "Contribution" shall mean any work of authorship, including - the original version of the Work and any modifications or additions - to that Work or Derivative Works thereof, that is intentionally - submitted to Licensor for inclusion in the Work by the copyright owner - or by an individual or Legal Entity authorized to submit on behalf of - the copyright owner. For the purposes of this definition, "submitted" - means any form of electronic, verbal, or written communication sent - to the Licensor or its representatives, including but not limited to - communication on electronic mailing lists, source code control systems, - and issue tracking systems that are managed by, or on behalf of, the - Licensor for the purpose of discussing and improving the Work, but - excluding communication that is conspicuously marked or otherwise - designated in writing by the copyright owner as "Not a Contribution." + 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. - "Contributor" shall mean Licensor and any individual or Legal Entity - on behalf of whom a Contribution has been received by Licensor and - subsequently incorporated within the Work. + (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.) - 2. Grant of Copyright License. Subject to the terms and conditions of - this License, each Contributor hereby grants to You a perpetual, - worldwide, non-exclusive, no-charge, royalty-free, irrevocable - copyright license to reproduce, prepare Derivative Works of, - publicly display, publicly perform, sublicense, and distribute the - Work and such Derivative Works in Source or Object form. + 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. - 3. Grant of Patent License. Subject to the terms and conditions of - this License, each Contributor hereby grants to You a perpetual, - worldwide, non-exclusive, no-charge, royalty-free, irrevocable - (except as stated in this section) patent license to make, have made, - use, offer to sell, sell, import, and otherwise transfer the Work, - where such license applies only to those patent claims licensable - by such Contributor that are necessarily infringed by their - Contribution(s) alone or by combination of their Contribution(s) - with the Work to which such Contribution(s) was submitted. If You - institute patent litigation against any entity (including a - cross-claim or counterclaim in a lawsuit) alleging that the Work - or a Contribution incorporated within the Work constitutes direct - or contributory patent infringement, then any patent licenses - granted to You under this License for that Work shall terminate - as of the date such litigation is filed. + 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. - 4. Redistribution. You may reproduce and distribute copies of the - Work or Derivative Works thereof in any medium, with or without - modifications, and in Source or Object form, provided that You - meet the following conditions: + 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. - (a) You must give any other recipients of the Work or - Derivative Works a copy of this License; and + 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. - (b) You must cause any modified files to carry prominent notices - stating that You changed the files; and + This option is useful when you wish to copy part of the code of + the Library into a program that is not a library. - (c) You must retain, in the Source form of any Derivative Works - that You distribute, all copyright, patent, trademark, and - attribution notices from the Source form of the Work, - excluding those notices that do not pertain to any part of - the Derivative Works; and + 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. - (d) If the Work includes a "NOTICE" text file as part of its - distribution, then any Derivative Works that You distribute must - include a readable copy of the attribution notices contained - within such NOTICE file, excluding those notices that do not - pertain to any part of the Derivative Works, in at least one - of the following places: within a NOTICE text file distributed - as part of the Derivative Works; within the Source form or - documentation, if provided along with the Derivative Works; or, - within a display generated by the Derivative Works, if and - wherever such third-party notices normally appear. The contents - of the NOTICE file are for informational purposes only and - do not modify the License. You may add Your own attribution - notices within Derivative Works that You distribute, alongside - or as an addendum to the NOTICE text from the Work, provided - that such additional attribution notices cannot be construed - as modifying the License. + 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. - You may add Your own copyright statement to Your modifications and - may provide additional or different license terms and conditions - for use, reproduction, or distribution of Your modifications, or - for any such Derivative Works as a whole, provided Your use, - reproduction, and distribution of the Work otherwise complies with - the conditions stated in this License. + 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. - 5. Submission of Contributions. Unless You explicitly state otherwise, - any Contribution intentionally submitted for inclusion in the Work - by You to the Licensor shall be under the terms and conditions of - this License, without any additional terms or conditions. - Notwithstanding the above, nothing herein shall supersede or modify - the terms of any separate license agreement you may have executed - with Licensor regarding such Contributions. + 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. - 6. Trademarks. This License does not grant permission to use the trade - names, trademarks, service marks, or product names of the Licensor, - except as required for reasonable and customary use in describing the - origin of the Work and reproducing the content of the NOTICE file. + 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. - 7. Disclaimer of Warranty. Unless required by applicable law or - agreed to in writing, Licensor provides the Work (and each - Contributor provides its Contributions) on an "AS IS" BASIS, - WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or - implied, including, without limitation, any warranties or conditions - of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A - PARTICULAR PURPOSE. You are solely responsible for determining the - appropriateness of using or redistributing the Work and assume any - risks associated with Your exercise of permissions under this License. + 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.) - 8. Limitation of Liability. In no event and under no legal theory, - whether in tort (including negligence), contract, or otherwise, - unless required by applicable law (such as deliberate and grossly - negligent acts) or agreed to in writing, shall any Contributor be - liable to You for damages, including any direct, indirect, special, - incidental, or consequential damages of any character arising as a - result of this License or out of the use or inability to use the - Work (including but not limited to damages for loss of goodwill, - work stoppage, computer failure or malfunction, or any and all - other commercial damages or losses), even if such Contributor - has been advised of the possibility of such damages. + 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 compile 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. - 9. Accepting Warranty or Additional Liability. While redistributing - the Work or Derivative Works thereof, You may choose to offer, - and charge a fee for, acceptance of support, warranty, indemnity, - or other liability obligations and/or rights consistent with this - License. However, in accepting such obligations, You may act only - on Your own behalf and on Your sole responsibility, not on behalf - of any other Contributor, and only if You agree to indemnify, - defend, and hold each Contributor harmless for any liability - incurred by, or claims asserted against, such Contributor by reason - of your accepting any such warranty or additional liability. + 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) 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. + + c) 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. + + d) 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 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. + + 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. - END OF TERMS AND CONDITIONS + 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. - APPENDIX: How to apply the Apache License to your work. + 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 to + 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. - To apply the Apache License to your work, attach the following - boilerplate notice, with the fields enclosed by brackets "[]" - replaced with your own identifying information. (Don't include - the brackets!) The text should be enclosed in the appropriate - comment syntax for the file format. We also recommend that a - file or class name and description of purpose be included on the - same "printed page" as the copyright notice for easier - identification within third-party archives. + 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. - Copyright [yyyy] [name of copyright owner] + 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. - Licensed under the Apache License, Version 2.0 (the "License"); - you may not use this file except in compliance with the License. - You may obtain a copy of the License at + This section is intended to make thoroughly clear what is believed to + be a consequence of the rest of this License. - http://www.apache.org/licenses/LICENSE-2.0 + 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. - Unless required by applicable law or agreed to in writing, software - distributed under the License is distributed on an "AS IS" BASIS, - WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. - See the License for the specific language governing permissions and - limitations under the License. - -### xalan - -Apache 2.0 - -https://xml.apache.org/xalan-j/ - -covers xalan.jar and serializer.jar - - Apache License - Version 2.0, January 2004 - http://www.apache.org/licenses/ + 13.

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.

Definitions. + NO WARRANTY - "License" shall mean the terms and conditions for use, reproduction, - and distribution as defined by Sections 1 through 9 of this document. + 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. - "Licensor" shall mean the copyright owner or entity authorized by - the copyright owner that is granting the License. + 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. - "Legal Entity" shall mean the union of the acting entity and all - other entities that control, are controlled by, or are under common - control with that entity.

You can do so by permitting + redistribution under these terms (or, alternatively, under the terms of the + ordinary General Public License). - "Source" form shall mean the preferred form for making modifications, - including but not limited to software source code, documentation - source, and configuration files. + 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. - "Object" form shall mean any form resulting from mechanical - transformation or translation of a Source form, including but - not limited to compiled object code, generated documentation, - and conversions to other media types. + + Copyright (C) - "Work" shall mean the work of authorship, whether in Source or - Object form, made available under the License, as indicated by a - copyright notice that is included in or attached to the work - (an example is provided in the Appendix below). + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public + License as published by the Free Software Foundation; either + version 2 of the License, or (at your option) any later version. - "Derivative Works" shall mean any work, whether in Source or Object - form, that is based on (or derived from) the Work and for which the - editorial revisions, annotations, elaborations, or other modifications - represent, as a whole, an original work of authorship. For the purposes - of this License, Derivative Works shall not include works that remain - separable from, or merely link (or bind by name) to the interfaces of, - the Work and Derivative Works thereof. + 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. See the GNU + Library General Public License for more details. - "Contribution" shall mean any work of authorship, including - the original version of the Work and any modifications or additions - to that Work or Derivative Works thereof, that is intentionally - submitted to Licensor for inclusion in the Work by the copyright owner - or by an individual or Legal Entity authorized to submit on behalf of - the copyright owner. For the purposes of this definition, "submitted" - means any form of electronic, verbal, or written communication sent - to the Licensor or its representatives, including but not limited to - communication on electronic mailing lists, source code control systems, - and issue tracking systems that are managed by, or on behalf of, the - Licensor for the purpose of discussing and improving the Work, but - excluding communication that is conspicuously marked or otherwise - designated in writing by the copyright owner as "Not a Contribution." + You should have received a copy of the GNU Library General Public + License along with this library; if not, write to the Free + Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, + MA 02110-1301, USA - "Contributor" shall mean Licensor and any individual or Legal Entity - on behalf of whom a Contribution has been received by Licensor and - subsequently incorporated within the Work. + Also add information on how to contact you by electronic and paper mail. - 2. Grant of Copyright License.

Here is a sample; alter the names: - 3. Grant of Patent License. Subject to the terms and conditions of - this License, each Contributor hereby grants to You a perpetual, - worldwide, non-exclusive, no-charge, royalty-free, irrevocable - (except as stated in this section) patent license to make, have made, - use, offer to sell, sell, import, and otherwise transfer the Work, - where such license applies only to those patent claims licensable - by such Contributor that are necessarily infringed by their - Contribution(s) alone or by combination of their Contribution(s) - with the Work to which such Contribution(s) was submitted. If You - institute patent litigation against any entity (including a - cross-claim or counterclaim in a lawsuit) alleging that the Work - or a Contribution incorporated within the Work constitutes direct - or contributory patent infringement, then any patent licenses - granted to You under this License for that Work shall terminate - as of the date such litigation is filed. + Yoyodyne, Inc., hereby disclaims all copyright interest in the + library `Frob' (a library for tweaking knobs) written by James Random Hacker. - 4.

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. + +### xerces + +Apache 2.0 + +https://xerces.apache.org/xerces2-j/ + - This license, the Library General Public License, applies to some - specially designated Free Software Foundation software, and to any - other libraries whose authors decide to use it. You can use it for - your libraries, too. + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ - 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. + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION - 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 library, or if you modify it. + 1. Definitions. - 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 a program 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. + "License" shall mean the terms and conditions for use, reproduction, + and distribution as defined by Sections 1 through 9 of this document. - Our method of protecting your rights has two steps: (1) copyright - the library, and (2) offer you this license which gives you legal - permission to copy, distribute and/or modify the library. + "Licensor" shall mean the copyright owner or entity authorized by + the copyright owner that is granting the License. - Also, for each distributor's protection, we want to make certain - that everyone understands that there is no warranty for this free - library. If the library is modified by someone else and passed on, we - want its recipients to know that what they have is not the original - version, 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 companies distributing free - software will individually obtain patent licenses, thus in effect - transforming the program into proprietary software. To prevent this, - we have made it clear that any patent must be licensed for everyone's - free use or not licensed at all. + "Legal Entity" shall mean the union of the acting entity and all + other entities that control, are controlled by, or are under common + control with that entity. For the purposes of this definition, + "control" means (i) the power, direct or indirect, to cause the + direction or management of such entity, whether by contract or + otherwise, or (ii) ownership of fifty percent (50%) or more of the + outstanding shares, or (iii) beneficial ownership of such entity. - Most GNU software, including some libraries, is covered by the ordinary - GNU General Public License, which was designed for utility programs. This - license, the GNU Library General Public License, applies to certain - designated libraries. This license is quite different from the ordinary - one; be sure to read it in full, and don't assume that anything in it is - the same as in the ordinary license. + "You" (or "Your") shall mean an individual or Legal Entity + exercising permissions granted by this License. - The reason we have a separate public license for some libraries is that - they blur the distinction we usually make between modifying or adding to a - program and simply using it. Linking a program with a library, without - changing the library, is in some sense simply using the library, and is - analogous to running a utility program or application program. However, in - a textual and legal sense, the linked executable is a combined work, a - derivative of the original library, and the ordinary General Public License - treats it as such. + "Source" form shall mean the preferred form for making modifications, + including but not limited to software source code, documentation + source, and configuration files. - Because of this blurred distinction, using the ordinary General - Public License for libraries did not effectively promote software - sharing, because most developers did not use the libraries. We - concluded that weaker conditions might promote sharing better. + "Object" form shall mean any form resulting from mechanical + transformation or translation of a Source form, including but + not limited to compiled object code, generated documentation, + and conversions to other media types. - However, unrestricted linking of non-free programs would deprive the - users of those programs of all benefit from the free status of the - libraries themselves. This Library General Public License is intended to - permit developers of non-free programs to use free libraries, while - preserving your freedom as a user of such programs to change the free - libraries that are incorporated in them. (We have not seen how to achieve - this as regards changes in header files, but we have achieved it as regards - changes in the actual functions of the Library.) The hope is that this - will lead to faster development of free libraries. + "Work" shall mean the work of authorship, whether in Source or + Object form, made available under the License, as indicated by a + copyright notice that is included in or attached to the work + (an example is provided in the Appendix below). - 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, while the latter only - works together with the library. + "Derivative Works" shall mean any work, whether in Source or Object + form, that is based on (or derived from) the Work and for which the + editorial revisions, annotations, elaborations, or other modifications + represent, as a whole, an original work of authorship. For the purposes + of this License, Derivative Works shall not include works that remain + separable from, or merely link (or bind by name) to the interfaces of, + the Work and Derivative Works thereof. - Note that it is possible for a library to be covered by the ordinary - General Public License rather than by this special one. - - GNU LIBRARY GENERAL PUBLIC LICENSE - TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + "Contribution" shall mean any work of authorship, including + the original version of the Work and any modifications or additions + to that Work or Derivative Works thereof, that is intentionally + submitted to Licensor for inclusion in the Work by the copyright owner + or by an individual or Legal Entity authorized to submit on behalf of + the copyright owner. For the purposes of this definition, "submitted" + means any form of electronic, verbal, or written communication sent + to the Licensor or its representatives, including but not limited to + communication on electronic mailing lists, source code control systems, + and issue tracking systems that are managed by, or on behalf of, the + Licensor for the purpose of discussing and improving the Work, but + excluding communication that is conspicuously marked or otherwise + designated in writing by the copyright owner as "Not a Contribution." - 0. This License Agreement applies to any software library which - contains a notice placed by the copyright holder or other authorized - party saying it may be distributed under the terms of this Library - General Public License (also called "this License"). Each licensee is - addressed as "you". + "Contributor" shall mean Licensor and any individual or Legal Entity + on behalf of whom a Contribution has been received by Licensor and + subsequently incorporated within the Work. - 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. + 2. Grant of Copyright License. Subject to the terms and conditions of + this License, each Contributor hereby grants to You a perpetual, + worldwide, non-exclusive, no-charge, royalty-free, irrevocable + copyright license to reproduce, prepare Derivative Works of, + publicly display, publicly perform, sublicense, and distribute the + Work and such Derivative Works in Source or Object form. - 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".) + 3. Grant of Patent License. Subject to the terms and conditions of + this License, each Contributor hereby grants to You a perpetual, + worldwide, non-exclusive, no-charge, royalty-free, irrevocable + (except as stated in this section) patent license to make, have made, + use, offer to sell, sell, import, and otherwise transfer the Work, + where such license applies only to those patent claims licensable + by such Contributor that are necessarily infringed by their + Contribution(s) alone or by combination of their Contribution(s) + with the Work to which such Contribution(s) was submitted. If You + institute patent litigation against any entity (including a + cross-claim or counterclaim in a lawsuit) alleging that the Work + or a Contribution incorporated within the Work constitutes direct + or contributory patent infringement, then any patent licenses + granted to You under this License for that Work shall terminate + as of the date such litigation is filed. - "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. + 4. Redistribution. You may reproduce and distribute copies of the + Work or Derivative Works thereof in any medium, with or without + modifications, and in Source or Object form, provided that You + meet the following conditions: - 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. + (a) You must give any other recipients of the Work or + Derivative Works a copy of this License; and - 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: + (b) You must cause any modified files to carry prominent notices + stating that You changed the files; and - a) The modified work must itself be a software library. + (c) You must retain, in the Source form of any Derivative Works + that You distribute, all copyright, patent, trademark, and + attribution notices from the Source form of the Work, + excluding those notices that do not pertain to any part of + the Derivative Works; and - b) You must cause the files modified to carry prominent notices - stating that you changed the files and the date of any change. + (d) If the Work includes a "NOTICE" text file as part of its + distribution, then any Derivative Works that You distribute must + include a readable copy of the attribution notices contained + within such NOTICE file, excluding those notices that do not + pertain to any part of the Derivative Works, in at least one + of the following places: within a NOTICE text file distributed + as part of the Derivative Works; within the Source form or + documentation, if provided along with the Derivative Works; or, + within a display generated by the Derivative Works, if and + wherever such third-party notices normally appear. The contents + of the NOTICE file are for informational purposes only and + do not modify the License. You may add Your own attribution + notices within Derivative Works that You distribute, alongside + or as an addendum to the NOTICE text from the Work, provided + that such additional attribution notices cannot be construed + as modifying the License. - 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. + You may add Your own copyright statement to Your modifications and + may provide additional or different license terms and conditions + for use, reproduction, or distribution of Your modifications, or + for any such Derivative Works as a whole, provided Your use, + reproduction, and distribution of the Work otherwise complies with + the conditions stated in 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. + 5. Submission of Contributions. Unless You explicitly state otherwise, + any Contribution intentionally submitted for inclusion in the Work + by You to the Licensor shall be under the terms and conditions of + this License, without any additional terms or conditions. + Notwithstanding the above, nothing herein shall supersede or modify + the terms of any separate license agreement you may have executed + with Licensor regarding such Contributions. - (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.) + 6. Trademarks. This License does not grant permission to use the trade + names, trademarks, service marks, or product names of the Licensor, + except as required for reasonable and customary use in describing the + origin of the Work and reproducing the content of the NOTICE file. - 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. + 7. Disclaimer of Warranty. Unless required by applicable law or + agreed to in writing, Licensor provides the Work (and each + Contributor provides its Contributions) on an "AS IS" BASIS, + WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or + implied, including, without limitation, any warranties or conditions + of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A + PARTICULAR PURPOSE. You are solely responsible for determining the + appropriateness of using or redistributing the Work and assume any + risks associated with Your exercise of permissions under this License. - 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. + 8. Limitation of Liability. In no event and under no legal theory, + whether in tort (including negligence), contract, or otherwise, + unless required by applicable law (such as deliberate and grossly + negligent acts) or agreed to in writing, shall any Contributor be + liable to You for damages, including any direct, indirect, special, + incidental, or consequential damages of any character arising as a + result of this License or out of the use or inability to use the + Work (including but not limited to damages for loss of goodwill, + work stoppage, computer failure or malfunction, or any and all + other commercial damages or losses), even if such Contributor + has been advised of the possibility of such damages. - 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. + 9. Accepting Warranty or Additional Liability. While redistributing + the Work or Derivative Works thereof, You may choose to offer, + and charge a fee for, acceptance of support, warranty, indemnity, + or other liability obligations and/or rights consistent with this + License. However, in accepting such obligations, You may act only + on Your own behalf and on Your sole responsibility, not on behalf + of any other Contributor, and only if You agree to indemnify, + defend, and hold each Contributor harmless for any liability + incurred by, or claims asserted against, such Contributor by reason + of your accepting any such warranty or additional liability. - 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. + END OF TERMS AND CONDITIONS - This option is useful when you wish to copy part of the code of - the Library into a program that is not a library. + APPENDIX: How to apply the Apache License to your work. - 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. + To apply the Apache License to your work, attach the following + boilerplate notice, with the fields enclosed by brackets "[]" + replaced with your own identifying information. (Don't include + the brackets!) The text should be enclosed in the appropriate + comment syntax for the file format. We also recommend that a + file or class name and description of purpose be included on the + same "printed page" as the copyright notice for easier + identification within third-party archives. - 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. + Copyright [yyyy] [name of copyright owner] - 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. + Licensed under the Apache License, Version 2.0 (the "License"); + you may not use this file except in compliance with the License. + You may obtain a copy of the License at - 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. + http://www.apache.org/licenses/LICENSE-2.0 - 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. + Unless required by applicable law or agreed to in writing, software + distributed under the License is distributed on an "AS IS" BASIS, + WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. + See the License for the specific language governing permissions and + limitations under the License. - 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.) + +### xml-apis + +Apache 2.0 + +https://xerces.apache.org/xml-commons/ + + Unless otherwise noted all files in XML Commons are covered under the + Apache License Version 2.0. Please read the LICENSE and NOTICE files. - 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 compile 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. + XML Commons contains some software and documentation that is covered + under a number of different licenses. This applies particularly to the + xml-commons/java/external/ directory. Most files under + xml-commons/java/external/ are covered under their respective + LICENSE.*.txt files; see the matching README.*.txt files for + descriptions. + - 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: + Apache License + Version 2.0, January 2004 + http://www.apache.org/licenses/ - 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.) + TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION - b) 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. + 1. Definitions. - c) 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. + "License" shall mean the terms and conditions for use, reproduction, + and distribution as defined by Sections 1 through 9 of this document. - d) Verify that the user has already received a copy of these - materials or that you have already sent this user a copy. + "Licensor" shall mean the copyright owner or entity authorized by + the copyright owner that is granting the License. - 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 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. + "Legal Entity" shall mean the union of the acting entity and all + other entities that control, are controlled by, or are under common + control with that entity. For the purposes of this definition, + "control" means (i) the power, direct or indirect, to cause the + direction or management of such entity, whether by contract or + otherwise, or (ii) ownership of fifty percent (50%) or more of the + outstanding shares, or (iii) beneficial ownership of such entity. - 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: + "You" (or "Your") shall mean an individual or Legal Entity + exercising permissions granted by this License. - 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. + "Source" form shall mean the preferred form for making modifications, + including but not limited to software source code, documentation + source, and configuration files. - 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. + "Object" form shall mean any form resulting from mechanical + transformation or translation of a Source form, including but + not limited to compiled object code, generated documentation, + and conversions to other media types. - 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. + "Work" shall mean the work of authorship, whether in Source or + Object form, made available under the License, as indicated by a + copyright notice that is included in or attached to the work + (an example is provided in the Appendix below). - 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. + "Derivative Works" shall mean any work, whether in Source or Object + form, that is based on (or derived from) the Work and for which the + editorial revisions, annotations, elaborations, or other modifications + represent, as a whole, an original work of authorship. For the purposes + of this License, Derivative Works shall not include works that remain + separable from, or merely link (or bind by name) to the interfaces of, + the Work and Derivative Works thereof. - 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 to - 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. + "Contribution" shall mean any work of authorship, including + the original version of the Work and any modifications or additions + to that Work or Derivative Works thereof, that is intentionally + submitted to Licensor for inclusion in the Work by the copyright owner + or by an individual or Legal Entity authorized to submit on behalf of + the copyright owner. For the purposes of this definition, "submitted" + means any form of electronic, verbal, or written communication sent + to the Licensor or its representatives, including but not limited to + communication on electronic mailing lists, source code control systems, + and issue tracking systems that are managed by, or on behalf of, the + Licensor for the purpose of discussing and improving the Work, but + excluding communication that is conspicuously marked or otherwise + designated in writing by the copyright owner as "Not a Contribution." - 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. + "Contributor" shall mean Licensor and any individual or Legal Entity + on behalf of whom a Contribution has been received by Licensor and + subsequently incorporated within the Work. - 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. + 2. Grant of Copyright License. Subject to the terms and conditions of + this License, each Contributor hereby grants to You a perpetual, + worldwide, non-exclusive, no-charge, royalty-free, irrevocable + copyright license to reproduce, prepare Derivative Works of, + publicly display, publicly perform, sublicense, and distribute the + Work and such Derivative Works in Source or Object form. - This section is intended to make thoroughly clear what is believed to - be a consequence of the rest of this License. + 3. Grant of Patent License. Subject to the terms and conditions of + this License, each Contributor hereby grants to You a perpetual, + worldwide, non-exclusive, no-charge, royalty-free, irrevocable + (except as stated in this section) patent license to make, have made, + use, offer to sell, sell, import, and otherwise transfer the Work, + where such license applies only to those patent claims licensable + by such Contributor that are necessarily infringed by their + Contribution(s) alone or by combination of their Contribution(s) + with the Work to which such Contribution(s) was submitted. If You + institute patent litigation against any entity (including a + cross-claim or counterclaim in a lawsuit) alleging that the Work + or a Contribution incorporated within the Work constitutes direct + or contributory patent infringement, then any patent licenses + granted to You under this License for that Work shall terminate + as of the date such litigation is filed. - 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. + 4. Redistribution. You may reproduce and distribute copies of the + Work or Derivative Works thereof in any medium, with or without + modifications, and in Source or Object form, provided that You + meet the following conditions: - 13. The Free Software Foundation may publish revised and/or new - versions of the Library 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. + (a) You must give any other recipients of the Work or + Derivative Works a copy of this License; and - 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. + (b) You must cause any modified files to carry prominent notices + stating that You changed the files; and - NO WARRANTY + (c) You must retain, in the Source form of any Derivative Works + that You distribute, all copyright, patent, trademark, and + attribution notices from the Source form of the Work, + excluding those notices that do not pertain to any part of + the Derivative Works; and - 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. + (d) If the Work includes a "NOTICE" text file as part of its + distribution, then any Derivative Works that You distribute must + include a readable copy of the attribution notices contained + within such NOTICE file, excluding those notices that do not + pertain to any part of the Derivative Works, in at least one + of the following places: within a NOTICE text file distributed + as part of the Derivative Works; within the Source form or + documentation, if provided along with the Derivative Works; or, + within a display generated by the Derivative Works, if and + wherever such third-party notices normally appear. The contents + of the NOTICE file are for informational purposes only and + do not modify the License. You may add Your own attribution + notices within Derivative Works that You distribute, alongside + or as an addendum to the NOTICE text from the Work, provided + that such additional attribution notices cannot be construed + as modifying the License. - 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. + You may add Your own copyright statement to Your modifications and + may provide additional or different license terms and conditions + for use, reproduction, or distribution of Your modifications, or + for any such Derivative Works as a whole, provided Your use, + reproduction, and distribution of the Work otherwise complies with + the conditions stated in this License. - END OF TERMS AND CONDITIONS - - Appendix: How to Apply These Terms to Your New Libraries + 5. Submission of Contributions. Unless You explicitly state otherwise, + any Contribution intentionally submitted for inclusion in the Work + by You to the Licensor shall be under the terms and conditions of + this License, without any additional terms or conditions. + Notwithstanding the above, nothing herein shall supersede or modify + the terms of any separate license agreement you may have executed + with Licensor regarding such Contributions. - 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). + 6. Trademarks. This License does not grant permission to use the trade + names, trademarks, service marks, or product names of the Licensor, + except as required for reasonable and customary use in describing the + origin of the Work and reproducing the content of the NOTICE file. - 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. + 7. Disclaimer of Warranty. Unless required by applicable law or + agreed to in writing, Licensor provides the Work (and each + Contributor provides its Contributions) on an "AS IS" BASIS, + WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or + implied, including, without limitation, any warranties or conditions + of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A + PARTICULAR PURPOSE. You are solely responsible for determining the + appropriateness of using or redistributing the Work and assume any + risks associated with Your exercise of permissions under this License. - - Copyright (C) + 8. Limitation of Liability. In no event and under no legal theory, + whether in tort (including negligence), contract, or otherwise, + unless required by applicable law (such as deliberate and grossly + negligent acts) or agreed to in writing, shall any Contributor be + liable to You for damages, including any direct, indirect, special, + incidental, or consequential damages of any character arising as a + result of this License or out of the use or inability to use the + Work (including but not limited to damages for loss of goodwill, + work stoppage, computer failure or malfunction, or any and all + other commercial damages or losses), even if such Contributor + has been advised of the possibility of such damages. - This library is free software; you can redistribute it and/or - modify it under the terms of the GNU Library General Public - License as published by the Free Software Foundation; either - version 2 of the License, or (at your option) any later version. + 9. Accepting Warranty or Additional Liability. While redistributing + the Work or Derivative Works thereof, You may choose to offer, + and charge a fee for, acceptance of support, warranty, indemnity, + or other liability obligations and/or rights consistent with this + License. However, in accepting such obligations, You may act only + on Your own behalf and on Your sole responsibility, not on behalf + of any other Contributor, and only if You agree to indemnify, + defend, and hold each Contributor harmless for any liability + incurred by, or claims asserted against, such Contributor by reason + of your accepting any such warranty or additional liability. - 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. See the GNU - Library General Public License for more details. + END OF TERMS AND CONDITIONS - You should have received a copy of the GNU Library General Public - License along with this library; if not, write to the Free - Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, - MA 02110-1301, USA + APPENDIX: How to apply the Apache License to your work. - Also add information on how to contact you by electronic and paper mail. + To apply the Apache License to your work, attach the following + boilerplate notice, with the fields enclosed by brackets "[]" + replaced with your own identifying information. (Don't include + the brackets!) The text should be enclosed in the appropriate + comment syntax for the file format. We also recommend that a + file or class name and description of purpose be included on the + same "printed page" as the copyright notice for easier + identification within third-party archives. - You should also get your employer (if you work as a programmer) or your - school, if any, to sign a "copyright disclaimer" for the library, if - necessary.
