-    Everyone is permitted to copy and distribute verbatim copies
-    of this license document, but changing it is not allowed.
+Being under the terms of the GNU General Public License v2.0 or later, according with
 
-### Preamble
+    LICENSES/GPL-2.0-or-later
 
-The licenses for most software are designed to take away your freedom
-to share and change it. By contrast, the GNU General Public License is
-intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users. This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it. (Some other Free Software Foundation software is covered by
-the GNU Lesser General Public License instead.) You can apply it to
-your programs, too.
 
-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.
+In addition, other licenses may also apply. Please see
 
-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 software, or if you modify it.
+    LICENSES/README.md
 
-For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have. You must make sure that they, too, receive or can get the
-source code. And you must show them these terms so they know their
-rights.
+for more details.
 
-We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
-
-Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software. If the software is modified by someone else and passed on,
-we want its recipients to know that what they have is not the
-original, 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 redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary. To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at
-all.
-
-The precise terms and conditions for copying, distribution and
-modification follow.
-
-### TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
-
-**0.** This License applies to any program or other work which
-contains a notice placed by the copyright holder saying it may be
-distributed under the terms of this General Public License. The
-"Program", below, refers to any such program or work, and a "work
-based on the Program" means either the Program or any derivative work
-under copyright law: that is to say, a work containing the Program or
-a portion of it, either verbatim or with modifications and/or
-translated into another language. (Hereinafter, translation is
-included without limitation in the term "modification".) Each licensee
-is addressed as "you".
-
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope. The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the Program
-(independent of having been made by running the Program). Whether that
-is true depends on what the Program does.
-
-**1.** You may copy and distribute verbatim copies of the Program's
-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 give any other recipients of the Program a copy of this License
-along with the Program.
-
-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 Program or any
-portion of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
-
-  
-**a)** You must cause the modified files to carry prominent notices
-stating that you changed the files and the date of any change.
-
-  
-**b)** You must cause any work that you distribute or publish, that in
-whole or in part contains or is derived from the Program or any part
-thereof, to be licensed as a whole at no charge to all third parties
-under the terms of this License.
-
-  
-**c)** If the modified program normally reads commands interactively
-when run, you must cause it, when started running for such interactive
-use in the most ordinary way, to print or display an announcement
-including an appropriate copyright notice and a notice that there is
-no warranty (or else, saying that you provide a warranty) and that
-users may redistribute the program under these conditions, and telling
-the user how to view a copy of this License. (Exception: if the
-Program itself is interactive but does not normally print such an
-announcement, your work based on the Program is not required to print
-an announcement.)
-
-These requirements apply to the modified work as a whole. If
-identifiable sections of that work are not derived from the Program,
-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 Program, 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.
-
-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 Program.
-
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
-
-**3.** You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
-
-  
-**a)** 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; or,
-
-  
-**b)** Accompany it with a written offer, valid for at least three
-years, to give any third party, for a charge no more than your cost of
-physically performing source distribution, a complete machine-readable
-copy of the corresponding source code, to be distributed under the
-terms of Sections 1 and 2 above on a medium customarily used for
-software interchange; or,
-
-  
-**c)** Accompany it with the information you received as to the offer
-to distribute corresponding source code. (This alternative is allowed
-only for noncommercial distribution and only if you received the
-program in object code or executable form with such an offer, in
-accord with Subsection b above.)
-
-The source code for a work means the preferred form of the work for
-making modifications to it. For an executable work, 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 executable. 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.
-
-If distribution of executable or 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 counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-**4.** You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License. Any attempt otherwise
-to copy, modify, sublicense or distribute the Program 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.
-
-**5.** 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 Program or its derivative works. These actions are
-prohibited by law if you do not accept this License. Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
-
-**6.** Each time you redistribute the Program (or any work based on
-the Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program 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.
-
-**7.** 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 Program at all. For
-example, if a patent license would not permit royalty-free
-redistribution of the Program 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
-Program.
-
-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.
-
-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.
-
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-**8.** If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program 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.
-
-**9.** The Free Software Foundation may publish revised and/or new
-versions of the 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 Program
-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 Program does not specify a
-version number of this License, you may choose any version ever
-published by the Free Software Foundation.
-
-**10.** If you wish to incorporate parts of the Program into other
-free programs whose distribution conditions are different, 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.
-
-**NO WARRANTY**
-
-**11.** BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO
-WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
-EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
-OTHER PARTIES PROVIDE THE PROGRAM "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
-PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME
-THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-**12.** 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 PROGRAM 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
-PROGRAM (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 PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF
-SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
-DAMAGES.
-
-### END OF TERMS AND CONDITIONS
-
-### How to Apply These Terms to Your New Programs
-
-If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these
-terms.
-
-To do so, attach the following notices to the program. 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.
-
-    one line to give the program's name and an idea of what it does.
-    Copyright (C) yyyy  name of author
-
-    This program is free software; you can redistribute it and/or
-    modify it under the terms of the GNU General Public License
-    as published by the Free Software Foundation; either version 2
-    of the License, or (at your option) any later version.
-
-    This program 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 General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program; if not, write to the Free Software
-    Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301, USA.
-
-Also add information on how to contact you by electronic and paper
-mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
-    type `show w'.  This is free software, and you are welcome
-    to redistribute it under certain conditions; type `show c' 
-    for details.
-
-The hypothetical commands \`show w' and \`show c' should show the
-appropriate parts of the General Public License. Of course, the
-commands you use may be called something other than \`show w' and
-\`show c'; they could even be mouse-clicks or menu items--whatever
-suits your program.
-
-You should also get your employer (if you work as a programmer) or
-your school, if any, to sign a "copyright disclaimer" for the program,
-if necessary. Here is a sample; alter the names:
-
-    Yoyodyne, Inc., hereby disclaims all copyright
-    interest in the program `Gnomovision'
-    (which makes passes at compilers) written 
-    by James Hacker.
-
-    signature of Ty Coon, 1 April 1989
-    Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program
-into proprietary programs. If your program is a subroutine library,
-you may consider it more useful to permit linking proprietary
-applications with the library. If this is what you want to do, use the
-[GNU Lesser General Public
-License](https://www.gnu.org/licenses/lgpl.html) instead of this
-License.
