| # GNU LESSER GENERAL PUBLIC LICENSE | |
| Version 3, 29 June 2007 | |
| Copyright (C) 2007 Free Software Foundation, Inc. | |
| <https://fsf.org/> | |
| Everyone is permitted to copy and distribute verbatim copies of this | |
| license document, but changing it is not allowed. | |
| This version of the GNU Lesser General Public License incorporates the | |
| terms and conditions of version 3 of the GNU General Public License, | |
| supplemented by the additional permissions listed below. | |
| ## 0. Additional Definitions. | |
| As used herein, "this License" refers to version 3 of the GNU Lesser | |
| General Public License, and the "GNU GPL" refers to version 3 of the | |
| GNU General Public License. | |
| "The Library" refers to a covered work governed by this License, other | |
| than an Application or a Combined Work as defined below. | |
| An "Application" is any work that makes use of an interface provided | |
| by the Library, but which is not otherwise based on the Library. | |
| Defining a subclass of a class defined by the Library is deemed a mode | |
| of using an interface provided by the Library. | |
| A "Combined Work" is a work produced by combining or linking an | |
| Application with the Library. The particular version of the Library | |
| with which the Combined Work was made is also called the "Linked | |
| Version". | |
| The "Minimal Corresponding Source" for a Combined Work means the | |
| Corresponding Source for the Combined Work, excluding any source code | |
| for portions of the Combined Work that, considered in isolation, are | |
| based on the Application, and not on the Linked Version. | |
| The "Corresponding Application Code" for a Combined Work means the | |
| object code and/or source code for the Application, including any data | |
| and utility programs needed for reproducing the Combined Work from the | |
| Application, but excluding the System Libraries of the Combined Work. | |
| ## 1. Exception to Section 3 of the GNU GPL. | |
| You may convey a covered work under sections 3 and 4 of this License | |
| without being bound by section 3 of the GNU GPL. | |
| ## 2. Conveying Modified Versions. | |
| If you modify a copy of the Library, and, in your modifications, a | |
| facility refers to a function or data to be supplied by an Application | |
| that uses the facility (other than as an argument passed when the | |
| facility is invoked), then you may convey a copy of the modified | |
| version: | |
| - a) under this License, provided that you make a good faith effort | |
| to ensure that, in the event an Application does not supply the | |
| function or data, the facility still operates, and performs | |
| whatever part of its purpose remains meaningful, or | |
| - b) under the GNU GPL, with none of the additional permissions of | |
| this License applicable to that copy. | |
| ## 3. Object Code Incorporating Material from Library Header Files. | |
| The object code form of an Application may incorporate material from a | |
| header file that is part of the Library. You may convey such object | |
| code under terms of your choice, provided that, if the incorporated | |
| material is not limited to numerical parameters, data structure | |
| layouts and accessors, or small macros, inline functions and templates | |
| (ten or fewer lines in length), you do both of the following: | |
| - a) Give prominent notice with each copy of the object code that | |
| the Library is used in it and that the Library and its use are | |
| covered by this License. | |
| - b) Accompany the object code with a copy of the GNU GPL and this | |
| license document. | |
| ## 4. Combined Works. | |
| You may convey a Combined Work under terms of your choice that, taken | |
| together, effectively do not restrict modification of the portions of | |
| the Library contained in the Combined Work and reverse engineering for | |
| debugging such modifications, if you also do each of the following: | |
| - a) Give prominent notice with each copy of the Combined Work that | |
| the Library is used in it and that the Library and its use are | |
| covered by this License. | |
| - b) Accompany the Combined Work with a copy of the GNU GPL and this | |
| license document. | |
| - c) For a Combined Work that displays copyright notices during | |
| execution, include the copyright notice for the Library among | |
| these notices, as well as a reference directing the user to the | |
| copies of the GNU GPL and this license document. | |
| - d) Do one of the following: | |
| - 0) Convey the Minimal Corresponding Source under the terms of | |
| this License, and the Corresponding Application Code in a form | |
| suitable for, and under terms that permit, the user to | |
| recombine or relink the Application with a modified version of | |
| the Linked Version to produce a modified Combined Work, in the | |
| manner specified by section 6 of the GNU GPL for conveying | |
| Corresponding Source. | |
| - 1) Use a suitable shared library mechanism for linking with | |
| the Library. A suitable mechanism is one that (a) uses at run | |
| time a copy of the Library already present on the user's | |
| computer system, and (b) will operate properly with a modified | |
| version of the Library that is interface-compatible with the | |
| Linked Version. | |
| - e) Provide Installation Information, but only if you would | |
| otherwise be required to provide such information under section 6 | |
| of the GNU GPL, and only to the extent that such information is | |
| necessary to install and execute a modified version of the | |
| Combined Work produced by recombining or relinking the Application | |
| with a modified version of the Linked Version. (If you use option | |
| 4d0, the Installation Information must accompany the Minimal | |
| Corresponding Source and Corresponding Application Code. If you | |
| use option 4d1, you must provide the Installation Information in | |
| the manner specified by section 6 of the GNU GPL for conveying | |
| Corresponding Source.) | |
| ## 5. Combined Libraries. | |
| You may place library facilities that are a work based on the Library | |
| side by side in a single library together with other library | |
| facilities that are not Applications and are not covered by this | |
| License, and convey such a combined library under terms of your | |
| choice, if you do both of the following: | |
| - a) Accompany the combined library with a copy of the same work | |
| based on the Library, uncombined with any other library | |
| facilities, conveyed under the terms of this License. | |
| - b) Give prominent notice with the combined library that part of it | |
| is a work based on the Library, and explaining where to find the | |
| accompanying uncombined form of the same work. | |
| ## 6. Revised Versions of the GNU Lesser General Public License. | |
| The Free Software Foundation may publish revised and/or new versions | |
| of the GNU Lesser General Public License from time to time. Such new | |
| versions will be similar in spirit to the present version, but may | |
| differ in detail to address new problems or concerns. | |
| Each version is given a distinguishing version number. If the Library | |
| as you received it specifies that a certain numbered version of the | |
| GNU Lesser General Public License "or any later version" applies to | |
| it, you have the option of following the terms and conditions either | |
| of that published version or of any later version published by the | |
| Free Software Foundation. If the Library as you received it does not | |
| specify a version number of the GNU Lesser General Public License, you | |
| may choose any version of the GNU Lesser General Public License ever | |
| published by the Free Software Foundation. | |
| If the Library as you received it specifies that a proxy can decide | |
| whether future versions of the GNU Lesser General Public License shall | |
| apply, that proxy's public statement of acceptance of any version is | |
| permanent authorization for you to choose that version for the | |
| Library. | |
