## 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 your good faith effort is made
  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,
    rather than copying library functions into the executable, 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.
