` 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.` |
||||
