glslang:
Here, glslang proper means core GLSL parsing, HLSL parsing, and SPIR-V code
generation. Glslang proper requires use of a number of licenses, one that covers
preprocessing and others that covers non-preprocessing.
Bison was removed long ago. You can build glslang from the source grammar,
using tools of your choice, without using bison or any bison files.
Other parts, outside of glslang proper, include:
-gl_types.h, only needed for OpenGL-like reflection, and can be left out of
  a parse and codegen project.  See it for its license.
-update_glslang_sources.py, which is not part of the project proper and does
  not need to be used.
-the SPIR-V "remapper", which is optional, but has the same license as
  glslang proper
-Google tests and SPIR-V tools, and anything in the external subdirectory
  are external and optional; see them for their respective licenses.
--------------------------------------------------------------------------------


The core of glslang-proper, minus the preprocessor is licenced as follows:

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.
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.

parser generator using the skeleton or a modified version thereof

the parser skeleton itself, you may (at your option) remove this
special exception, which will cause the skeleton and the resulting
Bison output files to be licensed under the GNU General Public

 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.
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.

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

Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA  02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing
it is not allowed.
[This is the first released version of the Lesser GPL.  It also counts as the successor of the GNU
Library Public License, version 2, hence the version number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to share and change it.  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.
This license, the Lesser General Public License, applies to some specially designated software
packages--typically libraries--of the Free Software Foundation and other authors who decide to use
it.  You can use it too, but we suggest you first think carefully about whether this license or the
ordinary General Public License is the better strategy to use in any particular case, based on the
explanations below.
When we speak of free software, we are referring to freedom of use, 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 and use pieces of it in new free programs; and that you are
nformed that you can do these things.
To protect your rights, we need to make restrictions that forbid distributors to deny you these rights
or to ask you to surrender these rights.  These restrictions translate to certain responsibilities for you
if you distribute copies of the library or if you modify it.
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 other code 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.
We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you
this license, which gives you legal permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no warranty for the free
library.  Also, if the library is modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original author's reputation will not be
affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free program.  We wish to
make sure that a company cannot effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder.  Therefore, we insist that any patent license obtained for a
version of the library must be consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the ordinary GNU General Public
License.  This license, the GNU Lesser General Public License, applies to certain designated
libraries, and is quite different from the ordinary General Public License.  We use this license for
certain libraries in order to permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a shared library, the
combination of the two is legally speaking a combined work, a derivative of the original library
The ordinary General Public License therefore permits such linking only if the entire combination
fits its criteria of freedom.  The Lesser General Public License permits more lax criteria for linking
other code with the library.
We call this license the "Lesser" General Public License because it does Less to protect the user's
freedom than the ordinary General Public License.  It also provides other free software developers
Less of an advantage over competing non-free programs.  These disadvantages are the reason we use
the ordinary General Public License for many libraries.  However, the Lesser license provides
advantages in certain special circumstances.
For example, on rare occasions, there may be a special need to encourage the widest possible use of a
certain library, so that it becomes a de-facto standard.  To achieve this, non-free programs must be
allowed to use the library.  A more frequent case is that a free library does the same job as widely
used non-free libraries.  In this case, there is little to gain by limiting the free library to free software
only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs enables a greater number
of people to use a large body of free software.  For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU operating system, as well as its
variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users' freedom, it does ensure
that the user of a program that is linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
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, whereas the latter must be combined with the library
in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
1. This License Agreement applies to any software library or other program which contains a notice
placed by the copyright holder or other authorized party saying it may be distributed under the terms
of this Lesser General Public License (also called "this License"). Each licensee is addressed as
you".
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.
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".)
"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.
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.
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 Sectio
1 above, provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices
 stating that you changed the files and the date of any change.
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.
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.
 (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.)
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.
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.
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.
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.
This option is useful when you wish to copy part of the code of the Library into a program that is not
a library.
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.
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.
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.
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.
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.
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.)
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 combine 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.
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) Use a suitable shared library mechanism for linking with the
 Library.  A suitable mechanism is one that (1) 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 (2)
 will operate properly with a modified version of the library, if
 the user installs one, as long as the modified version is
 interface-compatible with the version that the work was made with.
 c) 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.
 d) 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.
 e) 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 materials to be 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
ibrary 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.
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.
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 with 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.
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 o
 this License.
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.
13. The Free Software Foundation may publish revised and/or new versions of the 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 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.
NO WARRANTY
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.
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.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
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).
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.
 <\\one line to give the library's name and a brief idea of what it does./>
 Copyright (C) <\\year/>  <\\name of author/>
 This library is free software; you can redistribute it and/or
 modify it under the terms of the GNU Lesser General Public
 License as published by the Free Software Foundation; either
 version 2.1 of the License, or (at your option) any later version.
 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
 Lesser General Public License for more details.
 You should have received a copy of the GNU Lesser 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
Also add information on how to contact you by electronic and paper mail.
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.  Here is a sample; alter the names:
 Yoyodyne, Inc., hereby disclaims all copyright interest in the
  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

Open Source Software Licensed under the Dual License, i.e. both the conditions of the OpenSSL License and the original SSLeay license and others:
1. boringssl
Copyright (c)  Google Inc.
BoringSSL is a fork of OpenSSL. As such, large parts of it fall under OpenSSL
licensing. Files that are completely new have a Google copyright and an ISC
license. This license is reproduced at the bottom of this file.
Contributors to BoringSSL are required to follow the CLA rules for Chromium:
https://cla.developers.google.com/clas
Files in third_party/ have their own licenses, as described therein. The MIT
license, for third_party/fiat, which, unlike other third_party directories, is
compiled into non-test libraries, is included below.
The OpenSSL toolkit stays under a dual license, i.e. both the conditions of the
OpenSSL License and the original SSLeay license apply to the toolkit. See below
for the actual license texts. Actually both licenses are BSD-style Open Source
licenses. In case of any license issues related to OpenSSL please contact
openssl-core@openssl.org.
The following are Google-internal bug numbers where explicit permission from
some authors is recorded for use of their work. (This is purely for our own

Creative Commons Corporation ("Creative Commons") is not a law firm and
does not provide legal services or legal advice. Distribution of
Creative Commons public licenses does not create a lawyer-client or
other relationship. Creative Commons makes its licenses and related
information available on an "as-is" basis. Creative Commons gives no
warranties regarding its licenses, any material licensed under their
terms and conditions, or any related information. Creative Commons
disclaims all liability for damages resulting from their use to the

Using Creative Commons Public Licenses
Creative Commons public licenses provide a standard set of terms and
conditions that creators and other rights holders may use to share
original works of authorship and other material subject to copyright
and certain other rights specified in the public license below. The
following considerations are for informational purposes only, are not
exhaustive, and do not form part of our licenses.
  Considerations for licensors: Our public licenses are
  intended for use by those authorized to give the public
  permission to use material in ways otherwise restricted by
  copyright and certain other rights. Our licenses are
  irrevocable. Licensors should read and understand the terms
  and conditions of the license they choose before applying it.
  Licensors should also secure all rights necessary before
  applying our licenses so that the public can reuse the
  material as expected. Licensors should clearly mark any
  material not subject to the license. This includes other CC-
  licensed material, or material used under an exception or
  limitation to copyright. More considerations for licensors:
wiki.creativecommons.org/Considerations_for_licensors
  Considerations for the public: By using one of our public
  licenses, a licensor grants the public permission to use the
  licensed material under specified terms and conditions. If
  the licensor's permission is not necessary for any reason--for
  example, because of any applicable exception or limitation to
  copyright--then that use is not regulated by the license. Our
  licenses grant only permissions under copyright and certain
  other rights that a licensor has authority to grant. Use of
  the licensed material may still be restricted for other
  reasons, including because others have copyright or other
  rights in the material. A licensor may make special requests,
  such as asking that all changes be marked or described.
  Although not required by our licenses, you are encouraged to
  respect those requests where reasonable. More_considerations
  for the public:

  Rights.
d. Effective Technological Measures means those measures that, in the
  absence of proper authority, may not be circumvented under laws
  fulfilling obligations under Article 11 of the WIPO Copyright
  Treaty adopted on December 20, 1996, and/or similar international

e. Exceptions and Limitations means fair use, fair dealing, and/or
  any other exception or limitation to Copyright and Similar Rights
  that applies to Your use of the Licensed Material.
f. Licensed Material means the artistic or literary work, database,
  or other material to which the Licensor applied this Public
  License.
g. Licensed Rights means the rights granted to You subject to the
  terms and conditions of this Public License, which are limited to
  all Copyright and Similar Rights that apply to Your use of the
  Licensed Material and that the Licensor has authority to license.
h. Licensor means the individual(s) or entity(ies) granting rights
  under this Public License.
i. Share means to provide material to the public by any means or

  public may access the material from a place and at a time
  individually chosen by them.
j. Sui Generis Database Rights means rights other than copyright
  resulting from Directive 96/9/EC of the European Parliament and of
  the Council of 11 March 1996 on the legal protection of databases,

1. Subject to the terms and conditions of this Public License,
 the Licensor hereby grants You a worldwide, royalty-free,
 non-sublicensable, non-exclusive, irrevocable license to
 exercise the Licensed Rights in the Licensed Material to:
a. reproduce and Share the Licensed Material, in whole or
in part; and
b. produce, reproduce, and Share Adapted Material.
2. Exceptions and Limitations. For the avoidance of doubt, where
 Exceptions and Limitations apply to Your use, this Public
 License does not apply, and You do not need to comply with
 its terms and conditions.
3. Term. The term of this Public License is specified in Section
 6(a).
4. Media and formats; technical modifications allowed. The
 Licensor authorizes You to exercise the Licensed Rights in
 all media and formats whether now known or hereafter created,
 and to make technical modifications necessary to do so. The
 Licensor waives and/or agrees not to assert any right or
 authority to forbid You from making technical modifications
 necessary to exercise the Licensed Rights, including
 technical modifications necessary to circumvent Effective
 Technological Measures. For purposes of this Public License,
 simply making modifications authorized by this Section 2(a)
 (4) never produces Adapted Material.
5. Downstream recipients.
a. Offer from the Licensor --Licensed Material. Every
recipient of the Licensed Material automatically
receives an offer from the Licensor to exercise the
Licensed Rights under the terms and conditions of this
Public License.
b. No downstream restrictions. You may not offer or impose
any additional or different terms or conditions on, or
apply any Effective Technological Measures to, the
Licensed Material if doing so restricts exercise of the
Licensed Rights by any recipient of the Licensed
Material.
6. No endorsement. Nothing in this Public License constitutes or
 may be construed as permission to assert or imply that You
 are, or that Your use of the Licensed Material is, connected
 with, or sponsored, endorsed, or granted official status by,
 the Licensor or others designated to receive attribution as
 provided in Section 3(a)(1)(A)(i).
b. Other rights.
1. Moral rights, such as the right of integrity, are not
 licensed under this Public License, nor are publicity,
 privacy, and/or other similar personality rights; however, to
 the extent possible, the Licensor waives and/or agrees not to
 assert any such rights held by the Licensor to the limited
 extent necessary to allow You to exercise the Licensed
 Rights, but not otherwise.
2. Patent and trademark rights are not licensed under this
 Public License.
3. To the extent possible, the Licensor waives any right to
 collect royalties from You for the exercise of the Licensed
 Rights, whether directly or through a collecting society
 under any voluntary or waivable statutory or compulsory
 licensing scheme. In all other cases the Licensor expressly
 reserves any right to collect such royalties.
Section 3 --License Conditions.
Your exercise of the Licensed Rights is expressly made subject to the
following conditions.
a. Attribution.
1. If You Share the Licensed Material (including in modified
 form), You must:
a. retain the following if it is supplied by the Licensor
with the Licensed Material:
i. identification of the creator(s) of the Licensed
  Material and any others designated to receive
  attribution, in any reasonable manner requested by
  the Licensor (including by pseudonym if
  designated);
ii. a copyright notice;
iii. a notice that refers to this Public License;
iv. a notice that refers to the disclaimer of
  warranties;
v. a URI or hyperlink to the Licensed Material to the
  extent reasonably practicable;
b. indicate if You modified the Licensed Material and
retain an indication of any previous modifications; and
c. indicate the Licensed Material is licensed under this
Public License, and include the text of, or the URI or
hyperlink to, this Public License.
2. You may satisfy the conditions in Section 3(a)(1) in any
 reasonable manner based on the medium, means, and context in
 which You Share the Licensed Material. For example, it may be
 reasonable to satisfy the conditions by providing a URI or
 hyperlink to a resource that includes the required
 information.
3. If requested by the Licensor, You must remove any of the
 information required by Section 3(a)(1)(A) to the extent
 reasonably practicable.
4. If You Share Adapted Material You produce, the Adapter's
 License You apply must not prevent recipients of the Adapted
 Material from complying with this Public License.
Section 4 --Sui Generis Database Rights.
Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:
a. for the avoidance of doubt, Section 2(a)(1) grants You the right
  to extract, reuse, reproduce, and Share all or a substantial
  portion of the contents of the database;
b. if You include all or a substantial portion of the database
  contents in a database in which You have Sui Generis Database
  Rights, then the database in which You have Sui Generis Database
  Rights (but not its individual contents) is Adapted Material; and
c. You must comply with the conditions in Section 3(a) if You Share
  all or a substantial portion of the contents of the database.
For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.
Section 5 --Disclaimer of Warranties and Limitation of Liability.
a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
  EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
  AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
  ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
  IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
  WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
  PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
  ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
  KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
  ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
  TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
  NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
  INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
  COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
  USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
  ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
  DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
  IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
c. The disclaimer of warranties and limitation of liability provided
  above shall be interpreted in a manner that, to the extent
  possible, most closely approximates an absolute disclaimer and
  waiver of all liability.
Section 6 --Term and Termination.
a. This Public License applies for the term of the Copyright and
  Similar Rights licensed here. However, if You fail to comply with
  this Public License, then Your rights under this Public License
  terminate automatically.
b. Where Your right to use the Licensed Material has terminated under
  Section 6(a), it reinstates:
1. automatically as of the date the violation is cured, provided
 it is cured within 30 days of Your discovery of the
 violation; or
2. upon express reinstatement by the Licensor.
  For the avoidance of doubt, this Section 6(b) does not affect any
  right the Licensor may have to seek remedies for Your violations
  of this Public License.
c. For the avoidance of doubt, the Licensor may also offer the
  Licensed Material under separate terms or conditions or stop
  distributing the Licensed Material at any time; however, doing so
  will not terminate this Public License.
d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
  License.
Section 7 --Other Terms and Conditions.
a. The Licensor shall not be bound by any additional or different
  terms or conditions communicated by You unless expressly agreed.
b. Any arrangements, understandings, or agreements regarding the
  Licensed Material not stated herein are separate from and
  independent of the terms and conditions of this Public License.
Section 8 --Interpretation.
a. For the avoidance of doubt, this Public License does not, and
  shall not be interpreted to, reduce, limit, restrict, or impose
  conditions on any use of the Licensed Material that could lawfully
  be made without permission under this Public License.
b. To the extent possible, if any provision of this Public License is
  deemed unenforceable, it shall be automatically reformed to the
  minimum extent necessary to make it enforceable. If the provision
  cannot be reformed, it shall be severed from this Public License
  without affecting the enforceability of the remaining terms and
  conditions.
c. No term or condition of this Public License will be waived and no
  failure to comply consented to unless expressly agreed to by the
  Licensor.
d. Nothing in this Public License constitutes or may be interpreted
  as a limitation upon, or waiver of, any privileges and immunities
  that apply to the Licensor or You, including from the legal
  processes of any jurisdiction or authority.

non-exclusive license:
(a) under intellectual property rights (other than patent or trademark)
 Licensable by such Contributor to use, reproduce, make available,
 modify, display, perform, distribute, and otherwise exploit its

distributes such Contribution.
2.3. Limitations on Grant Scope
The licenses granted in this Section 2 are the only rights granted under
this License. No additional rights or licenses will be implied from the
distribution or licensing of Covered Software under this License.
Notwithstanding Section 2.1(b) above, no patent license is granted by a
Contributor:
(a) for any code that a Contributor has removed from Covered Software;
 or
(b) for infringements caused by: (i) Your and any other third party's
 modifications of Covered Software, or (ii) the combination of its
 Contributions with other software (except as part of its Contributor
 Version); or
(c) under Patent Claims infringed by Covered Software in the absence of
 its Contributions.
This License does not grant any rights in the trademarks, service marks,
or logos of any Contributor (except as may be necessary to comply with
the notice requirements in Section 3.4).
2.4. Subsequent Licenses
No Contributor makes additional grants as a result of Your choice to
distribute the Covered Software under a subsequent version of this
License (see Section 10.2) or under the terms of a Secondary License (if
permitted under the terms of Section 3.3).

to grant the rights to its Contributions conveyed by this License.
2.6. Fair Use

applicable copyright doctrines of fair use, fair dealing, or other
equivalents.
2.7. Conditions
Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
in Section 2.1.
3. Responsibilities
-------------------


3.1. Distribution of Source Form
All distribution of Covered Software in Source Code Form, including any
Modifications that You create or to which You contribute, must be under
the terms of this License. You must inform recipients that the Source
Code Form of the Covered Software is governed by the terms of this
License, and how they can obtain a copy of this License. You may not
attempt to alter or restrict the recipients' rights in the Source Code
Form.
3.2. Distribution of Executable Form
If You distribute Covered Software in Executable Form then:
(a) such Covered Software must also be made available in Source Code
 Form, as described in Section 3.1, and You must inform recipients of
 the Executable Form how they can obtain a copy of such Source Code
 Form by reasonable means in a timely manner, at a charge no more
 than the cost of distribution to the recipient; and
(b) You may distribute such Executable Form under the terms of this
 License, or sublicense it under different terms, provided that the
 license for the Executable Form does not attempt to limit or alter
 the recipients' rights in the Source Code Form under this License.
3.3. Distribution of a Larger Work
You may create and distribute a Larger Work under terms of Your choice,
provided that You also comply with the requirements of this License for
the Covered Software. If the Larger Work is a combination of Covered
Software with a work governed by one or more Secondary Licenses, and the
Covered Software is not Incompatible With Secondary Licenses, this
License permits You to additionally distribute such Covered Software
under the terms of such Secondary License(s), so that the recipient of
the Larger Work may, at their option, further distribute the Covered
Software under the terms of either this License or such Secondary
License(s).
3.4. Notices
You may not remove or alter the substance of any license notices
(including copyright notices, patent notices, disclaimers of warranty,
or limitations of liability) contained within the Source Code Form of
the Covered Software, except that You may alter any license notices to
the extent required to remedy known factual inaccuracies.
3.5. Application of Additional Terms
You may choose to offer, and to charge a fee for, warranty, support,
indemnity or liability obligations to one or more recipients of Covered
Software. However, You may do so only on Your own behalf, and not on
behalf of any Contributor. You must make it absolutely clear that any
such warranty, support, indemnity, or liability obligation is offered by
You alone, and You hereby agree to indemnify every Contributor for any
liability incurred by such Contributor as a result of warranty, support,
indemnity or liability terms You offer. You may include additional
disclaimers of warranty and limitations of liability specific to any
jurisdiction.
4. Inability to Comply Due to Statute or Regulation
---------------------------------------------------


If it is impossible for You to comply with any of the terms of this
License with respect to some or all of the Covered Software due to
statute, judicial order, or regulation then You must: (a) comply with
the terms of this License to the maximum extent possible; and (b)
describe the limitations and the code they affect. Such description must
be placed in a text file included with all distributions of the Covered
Software under this License. Except to the extent prohibited by statute
or regulation, such description must be sufficiently detailed for a
recipient of ordinary skill to be able to understand it.
5. Termination
--------------


5.1. The rights granted under this License will terminate automatically
if You fail to comply with any of its terms. However, if You become
compliant, then the rights granted under this License from a particular
Contributor are reinstated (a) provisionally, unless and until such
Contributor explicitly and finally terminates Your grants, and (b) on an
ongoing basis, if such Contributor fails to notify You of the
non-compliance by some reasonable means prior to 60 days after You have
come back into compliance. Moreover, Your grants from a particular
Contributor are reinstated on an ongoing basis if such Contributor
notifies You of the non-compliance by some reasonable means, this is the
first time You have received notice of non-compliance with this License
from such Contributor, and You become compliant prior to 30 days after
Your receipt of the notice.
5.2. If You initiate litigation against any entity by asserting a patent
infringement claim (excluding declaratory judgment actions,
counter-claims, and cross-claims) alleging that a Contributor Version
directly or indirectly infringes any patent, then the rights granted to
You by any and all Contributors for the Covered Software under Section
2.1 of this License shall terminate.
5.3. In the event of termination under Sections 5.1 or 5.2 above, all
end user license agreements (excluding distributors and resellers) which
have been validly granted by You or Your distributors under this License
prior to termination shall survive termination.

************************************************************************


6. Litigation
-------------


Any litigation relating to this License may be brought only in the
courts of a jurisdiction where the defendant maintains its principal
place of business and such litigation shall be governed by laws of that
jurisdiction, without reference to its conflict-of-law provisions.
Nothing in this Section shall prevent a party's ability to bring
cross-claims or counter-claims.
7. Miscellaneous
----------------


This License represents the complete agreement concerning the subject
matter hereof. If any provision of this License is held to be
unenforceable, such provision shall be reformed only to the extent
necessary to make it enforceable. Any law or regulation which provides
that the language of a contract shall be construed against the drafter
shall not be used to construe this License against a Contributor.
8. Versions of the License
---------------------------


10.1. New Versions
Mozilla Foundation is the license steward. Except as provided in Section
10.3, no one other than the license steward has the right to modify or
publish new versions of this License. Each version will be given a

You may distribute the Covered Software under the terms of the version
of the License under which You originally received the Covered Software,
or under the terms of any subsequent version published by the license
steward.
10.3. Modified Versions
If you create software not governed by this License, and you want to
create a new license for such software, you may create and use a
modified version of this License if you rename the license and remove
any references to the name of the license steward (except to note that
such modified license differs from this License).
10.4. Distributing Source Code Form that is Incompatible With Secondary
Licenses
If You choose to distribute Source Code Form that is Incompatible With
Secondary Licenses under the terms of this version of the License, the

1. INTRODUCTION
The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
of the MPEG specifications.
Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
individually for the purpose of encoding or decoding bit streams in products that are compliant with
the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
software may already be covered under those patent licenses when it is used for those licensed purposes only.
Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
applications information and documentation.

Copyright (c) Ffmpeg original author and authors
The source code can be obtained from https://github.com/FFmpeg/FFmpeg/tree/n4.2.3
Most files in FFmpeg are under the GNU Lesser General Public License version 2.1 or later (LGPL v2.1+). Read the file COPYING.LGPLv2.1 for details. Some other files have MIT/X11/BSD-style licenses. In combination the LGPL v2.1+ applies to FFmpeg.
Some optional parts of FFmpeg are licensed under the GNU General Public License version 2 or later (GPL v2+). See the file COPYING.GPLv2 for details. None of these parts are used by default, you have to explicitly pass --enable-gpl to configure to activate them. In this case, FFmpeg's license changes to GPL v2+.
Specifically, the GPL parts of FFmpeg are:
libpostproc
optional x86 optimization in the files
libavcodec/x86/flac_dsp_gpl.asm
libavcodec/x86/idct_mmx.c
libavfilter/x86/vf_removegrain.asm

Should you, for whatever reason, prefer to use version 3 of the (L)GPL, then the configure parameter --enable-version3 will activate this licensing option for you. Read the file COPYING.LGPLv3 or, if you have enabled GPL parts, COPYING.GPLv3 to learn the exact legal terms that apply in this case.
There are a handful of files under other licensing terms, namely:
The files libavcodec/jfdctfst.c, libavcodec/jfdctint_template.c and libavcodec/jrevdct.c are taken from libjpeg, see the top of the files for licensing details. Specifically note that you must credit the IJG in the documentation accompanying your program if you only distribute executables. You must also indicate any changes including additions and deletions to those three files in the documentation.
tests/reference.pnm is under the expat license.
External libraries
FFmpeg can be combined with a number of external libraries, which sometimes affect the licensing of binaries resulting from the combination.
Compatible libraries
The following libraries are under GPL:
frei0r
libcdio
librubberband
libvidstab
libx264
libx265
libxavs
libxvid
When combining them with FFmpeg, FFmpeg needs to be licensed as GPL as well by passing --enable-gpl to configure.
The OpenCORE and VisualOn libraries are under the Apache License 2.0. That license is incompatible with the LGPL v2.1 and the GPL v2, but not with version 3 of those licenses. So to combine these libraries with FFmpeg, the license version needs to be upgraded by passing --enable-version3 to configure.
Incompatible libraries
There are certain libraries you can combine with FFmpeg whose licenses are not compatible with the GPL and/or the LGPL. If you wish to enable these libraries, even in circumstances that their license may be incompatible, pass --enable-nonfree to configure. This will cause the resulting binary to be unredistributable.
The Fraunhofer FDK AAC and OpenSSL libraries are under licenses which are incompatible with the GPLv2 and v3. To the best of our knowledge, they are compatible with the LGPL.
Terms of the GNU Lesser General Public License, version 2.1 (LGPL-2.1):
GNU LESSER GENERAL PUBLIC LICENSE
Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA  02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing
it is not allowed.
[This is the first released version of the Lesser GPL.  It also counts as the successor of the GNU
Library Public License, version 2, hence the version number 2.1.]
 Preamble
The licenses for most software are designed to take away your freedom to share and change it.  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.
This license, the Lesser General Public License, applies to some specially designated software
packages--typically libraries--of the Free Software Foundation and other authors who decide to use
it.  You can use it too, but we suggest you first think carefully about whether this license or the
ordinary General Public License is the better strategy to use in any particular case, based on the
explanations below.
When we speak of free software, we are referring to freedom of use, 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 and use pieces of it in new free programs; and that you are
nformed that you can do these things.
To protect your rights, we need to make restrictions that forbid distributors to deny you these rights
or to ask you to surrender these rights.  These restrictions translate to certain responsibilities for you
if you distribute copies of the library or if you modify it.
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 other code 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.
We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you
this license, which gives you legal permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no warranty for the free
library.  Also, if the library is modified by someone else and passed on, the recipients should know
that what they have is not the original version, so that the original author's reputation will not be
affected by problems that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free program.  We wish to
make sure that a company cannot effectively restrict the users of a free program by obtaining a
restrictive license from a patent holder.  Therefore, we insist that any patent license obtained for a
version of the library must be consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the ordinary GNU General Public
License.  This license, the GNU Lesser General Public License, applies to certain designated
libraries, and is quite different from the ordinary General Public License.  We use this license for
certain libraries in order to permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a shared library, the
combination of the two is legally speaking a combined work, a derivative of the original library
The ordinary General Public License therefore permits such linking only if the entire combination
fits its criteria of freedom.  The Lesser General Public License permits more lax criteria for linking
other code with the library.
We call this license the "Lesser" General Public License because it does Less to protect the user's
freedom than the ordinary General Public License.  It also provides other free software developers
Less of an advantage over competing non-free programs.  These disadvantages are the reason we use
the ordinary General Public License for many libraries.  However, the Lesser license provides
advantages in certain special circumstances.
For example, on rare occasions, there may be a special need to encourage the widest possible use of a
certain library, so that it becomes a de-facto standard.  To achieve this, non-free programs must be
allowed to use the library.  A more frequent case is that a free library does the same job as widely
used non-free libraries.  In this case, there is little to gain by limiting the free library to free software
only, so we use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs enables a greater number
of people to use a large body of free software.  For example, permission to use the GNU C Library in
non-free programs enables many more people to use the whole GNU operating system, as well as its
variant, the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users' freedom, it does ensure
that the user of a program that is linked with the Library has the freedom and the wherewithal to run
that program using a modified version of the Library.
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, whereas the latter must be combined with the library
in order to run.
GNU LESSER GENERAL PUBLIC LICENSE
 TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
1. This License Agreement applies to any software library or other program which contains a notice
placed by the copyright holder or other authorized party saying it may be distributed under the terms
of this Lesser General Public License (also called "this License"). Each licensee is addressed as
you".
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.
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".)
"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.
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.
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 Sectio
1 above, provided that you also meet all of these conditions:
 a) The modified work must itself be a software library.
 b) You must cause the files modified to carry prominent notices
 stating that you changed the files and the date of any change.
 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.
 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.
 (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.)
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.
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.
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.
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.
This option is useful when you wish to copy part of the code of the Library into a program that is not
a library.
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.
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.
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.
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.
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.
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.)
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 combine 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.
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) Use a suitable shared library mechanism for linking with the
 Library.  A suitable mechanism is one that (1) 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 (2)
 will operate properly with a modified version of the library, if
 the user installs one, as long as the modified version is
 interface-compatible with the version that the work was made with.
 c) 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.
 d) 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.
 e) 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 materials to be 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
ibrary 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.
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.
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 with 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.
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 o
 this License.
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.
13. The Free Software Foundation may publish revised and/or new versions of the 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 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.
 NO WARRANTY
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.
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.

 How to Apply These Terms to Your New Libraries
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).
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.
 <\\one line to give the library's name and a brief idea of what it does./>
 Copyright (C) <\\year/>  <\\name of author/>
 This library is free software; you can redistribute it and/or
 modify it under the terms of the GNU Lesser General Public
 License as published by the Free Software Foundation; either
 version 2.1 of the License, or (at your option) any later version.
 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
 Lesser General Public License for more details.
 You should have received a copy of the GNU Lesser 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
Also add information on how to contact you by electronic and paper mail.
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.  Here is a sample; alter the names:
 Yoyodyne, Inc., hereby disclaims all copyright interest in the
  library `Frob' (a library for tweaking knobs) written by James Random Hacker.

Terms of the GNU Lesser General Public License, version 3 (LGPL-3):
 GNU LESSER GENERAL PUBLIC LICENSE
  Version 3, 29 June 2007
 Copyright (C) 2007 Free Software Foundation, Inc. <\\http://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.
1. 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:
5. 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.
6. 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.)
7. 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.
8. 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.

  Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,

 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
Preamble
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.
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.
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.
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.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
1. 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 a brief idea of what it does./>
 Copyright (C) <\\year/>  <\\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.

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 instead of this License.
Terms of the GNU General Public License, version 3 (GPL-3):
 GNU GENERAL PUBLIC LICENSE
  Version 3, 29 June 2007
 Copyright (C) 2007 Free Software Foundation, Inc. <\\http://fsf.org//>
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
 Preamble
  The GNU General Public License is a free, copyleft license for
software and other kinds of works.
  The licenses for most software and other practical works are designed
to take away your freedom to share and change the works.  By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.  We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors.  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
them 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.
  To protect your rights, we need to prevent others from denying you
these rights or asking you to surrender the rights.  Therefore, you have
certain responsibilities if you distribute copies of the software, or if
you modify it: responsibilities to respect the freedom of others.
  For example, if you distribute copies of such a program, whether
gratis or for a fee, you must pass on to the recipients the same
freedoms that you received.  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.
  Developers that use the GNU GPL protect your rights with two steps:
(1) assert copyright on the software, and (2) offer you this License
giving you legal permission to copy, distribute and/or modify it.
  For the developers' and authors' protection, the GPL clearly explains
that there is no warranty for this free software.  For both users' and
authors' sake, the GPL requires that modified versions be marked as
changed, so that their problems will not be attributed erroneously to
authors of previous versions.
  Some devices are designed to deny users access to install or run
modified versions of the software inside them, although the manufacturer
can do so.  This is fundamentally incompatible with the aim of
protecting users' freedom to change the software.  The systematic
pattern of such abuse occurs in the area of products for individuals to
use, which is precisely where it is most unacceptable.  Therefore, we
have designed this version of the GPL to prohibit the practice for those
products.  If such problems arise substantially in other domains, we
stand ready to extend this provision to those domains in future versions
of the GPL, as needed to protect the freedom of users.
  Finally, every program is threatened constantly by software patents.
States should not allow patents to restrict development and use of
software on general-purpose computers, but in those that do, we wish to
avoid the special danger that patents applied to a free program could
make it effectively proprietary.  To prevent this, the GPL assures that
patents cannot be used to render the program non-free.
  The precise terms and conditions for copying, distribution and
modification follow.
  TERMS AND CONDITIONS
1. Definitions.
  "This License" refers to version 3 of the GNU General Public License.
  "Copyright" also means copyright-like laws that apply to other kinds of
works, such as semiconductor masks.
  "The Program" refers to any copyrightable work licensed under this
License.  Each licensee is addressed as "you".  "Licensees" and
"recipients" may be individuals or organizations.
  To "modify" a work means to copy from or adapt all or part of the work
in a fashion requiring copyright permission, other than the making of an
exact copy.  The resulting work is called a "modified version" of the
earlier work or a work "based on" the earlier work.
  A "covered work" means either the unmodified Program or a work based
on the Program.
  To "propagate" a work means to do anything with it that, without
permission, would make you directly or secondarily liable for
infringement under applicable copyright law, except executing it on a
computer or modifying a private copy.  Propagation includes copying,
distribution (with or without modification), making available to the
public, and in some countries other activities as well.
  To "convey" a work means any kind of propagation that enables other
parties to make or receive copies.  Mere interaction with a user through
a computer network, with no transfer of a copy, is not conveying.
  An interactive user interface displays "Appropriate Legal Notices"
to the extent that it includes a convenient and prominently visible
feature that (1) displays an appropriate copyright notice, and (2)
tells the user that there is no warranty for the work (except to the
extent that warranties are provided), that licensees may convey the
work under this License, and how to view a copy of this License.  If
the interface presents a list of user commands or options, such as a
menu, a prominent item in the list meets this criterion.
1. Source Code.
  The "source code" for a work means the preferred form of the work
for making modifications to it.  "Object code" means any non-source
form of a work.
  A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
  The "System Libraries" of an executable work include anything, other
than the work as a whole, that (a) is included in the normal form of
packaging a Major Component, but which is not part of that Major
Component, and (b) serves only to enable use of the work with that
Major Component, or to implement a Standard Interface for which an
implementation is available to the public in source code form.  A
"Major Component", in this context, means a major essential component
(kernel, window system, and so on) of the specific operating system
(if any) on which the executable work runs, or a compiler used to
produce the work, or an object code interpreter used to run it.
  The "Corresponding Source" for a work in object code form means all
the source code needed to generate, install, and (for an executable
work) run the object code and to modify the work, including scripts to
control those activities.  However, it does not include the work's
System Libraries, or general-purpose tools or generally available free
programs which are used unmodified in performing those activities but
which are not part of the work.  For example, Corresponding Source
includes interface definition files associated with source files for
the work, and the source code for shared libraries and dynamically
linked subprograms that the work is specifically designed to require,
such as by intimate data communication or control flow between those
subprograms and other parts of the work.
  The Corresponding Source need not include anything that users
can regenerate automatically from other parts of the Corresponding
Source.
  The Corresponding Source for a work in source code form is that
same work.
2. Basic Permissions.
  All rights granted under this License are granted for the term of
copyright on the Program, and are irrevocable provided the stated
conditions are met.  This License explicitly affirms your unlimited
permission to run the unmodified Program.  The output from running a
covered work is covered by this License only if the output, given its
content, constitutes a covered work.  This License acknowledges your
rights of fair use or other equivalent, as provided by copyright law.
  You may make, run and propagate covered works that you do not
convey, without conditions so long as your license otherwise remains
in force.  You may convey covered works to others for the sole purpose
of having them make modifications exclusively for you, or provide you
with facilities for running those works, provided that you comply with
the terms of this License in conveying all material for which you do
not control copyright.  Those thus making or running the covered works
for you must do so exclusively on your behalf, under your direction
and control, on terms that prohibit them from making any copies of
your copyrighted material outside their relationship with you.
  Conveying under any other circumstances is permitted solely under
the conditions stated below.  Sublicensing is not allowed; section 10
makes it unnecessary.
3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  No covered work shall be deemed part of an effective technological
measure under any applicable law fulfilling obligations under article
11 of the WIPO copyright treaty adopted on 20 December 1996, or
similar laws prohibiting or restricting circumvention of such
measures.
  When you convey a covered work, you waive any legal power to forbid
circumvention of technological measures to the extent such circumvention
is effected by exercising rights under this License with respect to
the covered work, and you disclaim any intention to limit operation or
modification of the work as a means of enforcing, against the work's
users, your or third parties' legal rights to forbid circumvention of
technological measures.
4. Conveying Verbatim Copies.
  You may convey 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;
keep intact all notices stating that this License and any
non-permissive terms added in accord with section 7 apply to the code;
keep intact all notices of the absence of any warranty; and give all
recipients a copy of this License along with the Program.
  You may charge any price or no price for each copy that you convey,
and you may offer support or warranty protection for a fee.
5. Conveying Modified Source Versions.
  You may convey a work based on the Program, or the modifications to
produce it from the Program, in the form of source code under the
terms of section 4, provided that you also meet all of these conditions:
 a) The work must carry prominent notices stating that you modified
 it, and giving a relevant date.
 b) The work must carry prominent notices stating that it is
 released under this License and any conditions added under section
 7.  This requirement modifies the requirement in section 4 to
 "keep intact all notices".
 c) You must license the entire work, as a whole, under this
 License to anyone who comes into possession of a copy.  This
 License will therefore apply, along with any applicable section 7
 additional terms, to the whole of the work, and all its parts,
 regardless of how they are packaged.  This License gives no
 permission to license the work in any other way, but it does not
 invalidate such permission if you have separately received it.
 d) If the work has interactive user interfaces, each must display
 Appropriate Legal Notices; however, if the Program has interactive
 interfaces that do not display Appropriate Legal Notices, your
 work need not make them do so.
  A compilation of a covered work with other separate and independent
works, which are not by their nature extensions of the covered work,
and which are not combined with it such as to form a larger program,
in or on a volume of a storage or distribution medium, is called an
"aggregate" if the compilation and its resulting copyright are not
used to limit the access or legal rights of the compilation's users
beyond what the individual works permit.  Inclusion of a covered work
in an aggregate does not cause this License to apply to the other
parts of the aggregate.
6. Conveying Non-Source Forms.
  You may convey a covered work in object code form under the terms
of sections 4 and 5, provided that you also convey the
machine-readable Corresponding Source under the terms of this License,
in one of these ways:
 a) Convey the object code in, or embodied in, a physical product
 (including a physical distribution medium), accompanied by the
 Corresponding Source fixed on a durable physical medium
 customarily used for software interchange.
 b) Convey the object code in, or embodied in, a physical product
 (including a physical distribution medium), accompanied by a
 written offer, valid for at least three years and valid for as
 long as you offer spare parts or customer support for that product
 model, to give anyone who possesses the object code either (1) a
 copy of the Corresponding Source for all the software in the
 product that is covered by this License, on a durable physical
 medium customarily used for software interchange, for a price no
 more than your reasonable cost of physically performing this
 conveying of source, or (2) access to copy the
 Corresponding Source from a network server at no charge.
 c) Convey individual copies of the object code with a copy of the
 written offer to provide the Corresponding Source.  This
 alternative is allowed only occasionally and noncommercially, and
 only if you received the object code with such an offer, in accord
 with subsection 6b.
 d) Convey the object code by offering access from a designated
 place (gratis or for a charge), and offer equivalent access to the
 Corresponding Source in the same way through the same place at no
 further charge.  You need not require recipients to copy the
 Corresponding Source along with the object code.  If the place to
 copy the object code is a network server, the Corresponding Source
 may be on a different server (operated by you or a third party)
 that supports equivalent copying facilities, provided you maintain
 clear directions next to the object code saying where to find the
 Corresponding Source.  Regardless of what server hosts the
 Corresponding Source, you remain obligated to ensure that it is
 available for as long as needed to satisfy these requirements.
 e) Convey the object code using peer-to-peer transmission, provided
 you inform other peers where the object code and Corresponding
 Source of the work are being offered to the general public at no
 charge under subsection 6d.
  A separable portion of the object code, whose source code is excluded
from the Corresponding Source as a System Library, need not be
included in conveying the object code work.
  A "User Product" is either (1) a "consumer product", which means any
tangible personal property which is normally used for personal, family,
or household purposes, or (2) anything designed or sold for incorporation
into a dwelling.  In determining whether a product is a consumer product,
doubtful cases shall be resolved in favor of coverage.  For a particular
product received by a particular user, "normally used" refers to a
typical or common use of that class of product, regardless of the status
of the particular user or of the way in which the particular user
actually uses, or expects or is expected to use, the product.  A product
is a consumer product regardless of whether the product has substantial
commercial, industrial or non-consumer uses, unless such uses represent
the only significant mode of use of the product.
  "Installation Information" for a User Product means any methods,
procedures, authorization keys, or other information required to install
and execute modified versions of a covered work in that User Product from
a modified version of its Corresponding Source.  The information must
suffice to ensure that the continued functioning of the modified object
code is in no case prevented or interfered with solely because
modification has been made.
  If you convey an object code work under this section in, or with, or
specifically for use in, a User Product, and the conveying occurs as
part of a transaction in which the right of possession and use of the
User Product is transferred to the recipient in perpetuity or for a
fixed term (regardless of how the transaction is characterized), the
Corresponding Source conveyed under this section must be accompanied
by the Installation Information.  But this requirement does not apply
if neither you nor any third party retains the ability to install
modified object code on the User Product (for example, the work has
been installed in ROM).
  The requirement to provide Installation Information does not include a
requirement to continue to provide support service, warranty, or updates
for a work that has been modified or installed by the recipient, or for
the User Product in which it has been modified or installed.  Access to a
network may be denied when the modification itself materially and
adversely affects the operation of the network or violates the rules and
protocols for communication across the network.
  Corresponding Source conveyed, and Installation Information provided,
in accord with this section must be in a format that is publicly
documented (and with an implementation available to the public in
source code form), and must require no special password or key for
unpacking, reading or copying.
7. Additional Terms.
  "Additional permissions" are terms that supplement the terms of this
License by making exceptions from one or more of its conditions.
Additional permissions that are applicable to the entire Program shall
be treated as though they were included in this License, to the extent
that they are valid under applicable law.  If additional permissions
apply only to part of the Program, that part may be used separately
under those permissions, but the entire Program remains governed by
this License without regard to the additional permissions.
  When you convey a copy of a covered work, you may at your option
remove any additional permissions from that copy, or from any part of
it.  (Additional permissions may be written to require their own
removal in certain cases when you modify the work.)  You may place
additional permissions on material, added by you to a covered work,
for which you have or can give appropriate copyright permission.
  Notwithstanding any other provision of this License, for material you
add to a covered work, you may (if authorized by the copyright holders of
that material) supplement the terms of this License with terms:
 a) Disclaiming warranty or limiting liability differently from the
 terms of sections 15 and 16 of this License; or
 b) Requiring preservation of specified reasonable legal notices or
 author attributions in that material or in the Appropriate Legal
 Notices displayed by works containing it; or
 c) Prohibiting misrepresentation of the origin of that material, or
 requiring that modified versions of such material be marked in
 reasonable ways as different from the original version; or
 d) Limiting the use for publicity purposes of names of licensors or
 authors of the material; or
 e) Declining to grant rights under trademark law for use of some
 trade names, trademarks, or service marks; or
 f) Requiring indemnification of licensors and authors of that
 material by anyone who conveys the material (or modified versions of
 it) with contractual assumptions of liability to the recipient, for
 any liability that these contractual assumptions directly impose on
 those licensors and authors.
  All other non-permissive additional terms are considered "further
restrictions" within the meaning of section 10.  If the Program as you
received it, or any part of it, contains a notice stating that it is
governed by this License along with a term that is a further
restriction, you may remove that term.  If a license document contains
a further restriction but permits relicensing or conveying under this
License, you may add to a covered work material governed by the terms
of that license document, provided that the further restriction does
not survive such relicensing or conveying.
  If you add terms to a covered work in accord with this section, you
must place, in the relevant source files, a statement of the
additional terms that apply to those files, or a notice indicating
where to find the applicable terms.
  Additional terms, permissive or non-permissive, may be stated in the
form of a separately written license, or stated as exceptions;
the above requirements apply either way.
8. Termination.
  You may not propagate or modify a covered work except as expressly
provided under this License.  Any attempt otherwise to propagate or
modify it is void, and will automatically terminate your rights under
this License (including any patent licenses granted under the third
paragraph of section 11).
  However, if you cease all violation of this License, then your
license from a particular copyright holder is reinstated (a)
provisionally, unless and until the copyright holder explicitly and
finally terminates your license, and (b) permanently, if the copyright
holder fails to notify you of the violation by some reasonable means
prior to 60 days after the cessation.
  Moreover, your license from a particular copyright holder is
reinstated permanently if the copyright holder notifies you of the
violation by some reasonable means, this is the first time you have
received notice of violation of this License (for any work) from that
copyright holder, and you cure the violation prior to 30 days after
your receipt of the notice.
  Termination of your rights under this section does not terminate the
licenses of parties who have received copies or rights from you under
this License.  If your rights have been terminated and not permanently
reinstated, you do not qualify to receive new licenses for the same
material under section 10.
9. Acceptance Not Required for Having Copies.
  You are not required to accept this License in order to receive or
run a copy of the Program.  Ancillary propagation of a covered work
occurring solely as a consequence of using peer-to-peer transmission
to receive a copy likewise does not require acceptance.  However,
nothing other than this License grants you permission to propagate or
modify any covered work.  These actions infringe copyright if you do
not accept this License.  Therefore, by modifying or propagating a
covered work, you indicate your acceptance of this License to do so.
10. Automatic Licensing of Downstream Recipients.
  Each time you convey a covered work, the recipient automatically
receives a license from the original licensors, to run, modify and
propagate that work, subject to this License.  You are not responsible
for enforcing compliance by third parties with this License.
  An "entity transaction" is a transaction transferring control of an
organization, or substantially all assets of one, or subdividing an
organization, or merging organizations.  If propagation of a covered
work results from an entity transaction, each party to that
transaction who receives a copy of the work also receives whatever
licenses to the work the party's predecessor in interest had or could
give under the previous paragraph, plus a right to possession of the
Corresponding Source of the work from the predecessor in interest, if
the predecessor has it or can get it with reasonable efforts.
  You may not impose any further restrictions on the exercise of the
rights granted or affirmed under this License.  For example, you may
not impose a license fee, royalty, or other charge for exercise of
rights granted under this License, and you may not initiate litigation
(including a cross-claim or counterclaim in a lawsuit) alleging that
any patent claim is infringed by making, using, selling, offering for
sale, or importing the Program or any portion of it.
11. Patents.
  A "contributor" is a copyright holder who authorizes use under this
License of the Program or a work on which the Program is based.  The
work thus licensed is called the contributor's "contributor version".
  A contributor's "essential patent claims" are all patent claims
owned or controlled by the contributor, whether already acquired or
hereafter acquired, that would be infringed by some manner, permitted
by this License, of making, using, or selling its contributor version,
but do not include claims that would be infringed only as a
consequence of further modification of the contributor version.  For
purposes of this definition, "control" includes the right to grant
patent sublicenses in a manner consistent with the requirements of
this License.
  Each contributor grants you a non-exclusive, worldwide, royalty-free
patent license under the contributor's essential patent claims, to
make, use, sell, offer for sale, import and otherwise run, modify and
propagate the contents of its contributor version.
  In the following three paragraphs, a "patent license" is any express
agreement or commitment, however denominated, not to enforce a patent
(such as an express permission to practice a patent or covenant not to
sue for patent infringement).  To "grant" such a patent license to a
party means to make such an agreement or commitment not to enforce a
patent against the party.
  If you convey a covered work, knowingly relying on a patent license,
and the Corresponding Source of the work is not available for anyone
to copy, free of charge and under the terms of this License, through a
publicly available network server or other readily accessible means,
then you must either (1) cause the Corresponding Source to be so
available, or (2) arrange to deprive yourself of the benefit of the
patent license for this particular work, or (3) arrange, in a manner
consistent with the requirements of this License, to extend the patent
license to downstream recipients.  "Knowingly relying" means you have
actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient's use of the covered work
in a country, would infringe one or more identifiable patents in that
country that you have reason to believe are valid.
  If, pursuant to or in connection with a single transaction or
arrangement, you convey, or propagate by procuring conveyance of, a
covered work, and grant a patent license to some of the parties
receiving the covered work authorizing them to use, propagate, modify
or convey a specific copy of the covered work, then the patent license
you grant is automatically extended to all recipients of the covered
work and works based on it.
  A patent license is "discriminatory" if it does not include within
the scope of its coverage, prohibits the exercise of, or is
conditioned on the non-exercise of one or more of the rights that are
specifically granted under this License.  You may not convey a covered
work if you are a party to an arrangement with a third party that is
in the business of distributing software, under which you make payment
to the third party based on the extent of your activity of conveying
the work, and under which the third party grants, to any of the
parties who would receive the covered work from you, a discriminatory
patent license (a) in connection with copies of the covered work
conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that
contain the covered work, unless you entered into that arrangement,
or that patent license was granted, prior to 28 March 2007.
  Nothing in this License shall be construed as excluding or limiting
any implied license or other defenses to infringement that may
otherwise be available to you under applicable patent law.
12. No Surrender of Others' Freedom.
  If 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 convey a
covered work so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may
not convey it at all.  For example, if you agree to terms that obligate you
to collect a royalty for further conveying from those to whom you convey
the Program, the only way you could satisfy both those terms and this
License would be to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
  Notwithstanding any other provision of this License, you have
permission to link or combine any covered work with a work licensed
under version 3 of the GNU Affero General Public License into a single
combined work, and to convey the resulting work.  The terms of this
License will continue to apply to the part which is the covered work,
but the special requirements of the GNU Affero General Public License,
section 13, concerning interaction through a network will apply to the
combination as such.
14. Revised Versions of this License.
  The Free Software Foundation may publish revised and/or new versions of
the GNU 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 that a certain numbered version of the GNU General
Public License "or any later version" applies to it, you have the
option of following the terms and conditions either of that numbered
version or of any later version published by the Free Software
Foundation.  If the Program does not specify a version number of the
GNU General Public License, you may choose any version ever published
by the Free Software Foundation.
  If the Program specifies that a proxy can decide which future
versions of the GNU General Public License can be used, that proxy's
public statement of acceptance of a version permanently authorizes you
to choose that version for the Program.
  Later license versions may give you additional or different
permissions.  However, no additional obligations are imposed on any
author or copyright holder as a result of your choosing to follow a
later version.
15. Disclaimer of Warranty.
  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.
16. Limitation of Liability.
  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
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.
17. Interpretation of Sections 15 and 16.
  If the disclaimer of warranty and limitation of liability provided
above cannot be given local legal effect according to their terms,
reviewing courts shall apply local law that most closely approximates
an absolute waiver of all civil liability in connection with the
Program, unless a warranty or assumption of liability accompanies a
copy of the Program in return for a fee.
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
state 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 a brief idea of what it does./>
 Copyright (C) <\\year/>  <\\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 3 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, see <\\http://www.gnu.org/licenses//>.
Also add information on how to contact you by electronic and paper mail.
  If the program does terminal interaction, make it output a short
notice like this when it starts in an interactive mode:
 <\\program/>  Copyright (C) <\\year/>  <\\name of author/>
 This program 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, your program's commands
might be different; for a GUI interface, you would use an "about box".
  You should also get your employer (if you work as a programmer) or school,
if any, to sign a "copyright disclaimer" for the program, if necessary.
For more information on this, and how to apply and follow the GNU GPL, see
<\\http://www.gnu.org/licenses//>.
  The GNU 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 instead of this License.  But first, please read
<\\http://www.gnu.org/philosophy/why-not-lgpl.html/>.

© Copyright  1995 -2012 Fraunhofer-Gesellschaft zur Förderung der angewandten Forschung e.V.
  All rights reserved.
1. INTRODUCTION
The Fraunhofer FDK AAC Codec Library for Android ("FDK AAC Codec") is software that implements
the MPEG Advanced Audio Coding ("AAC") encoding and decoding scheme for digital audio.
This FDK AAC Codec software is intended to be used on a wide variety of Android devices.
AAC's HE-AAC and HE-AAC v2 versions are regarded as today's most efficient general perceptual
audio codecs. AAC-ELD is considered the best-performing full-bandwidth communications codec by
independent studies and is widely deployed. AAC has been standardized by ISO and IEC as part
of the MPEG specifications.
Patent licenses for necessary patent claims for the FDK AAC Codec (including those of Fraunhofer)
may be obtained through Via Licensing (www.vialicensing.com) or through the respective patent owners
individually for the purpose of encoding or decoding bit streams in products that are compliant with
the ISO/IEC MPEG audio standards. Please note that most manufacturers of Android devices already license
these patent claims through Via Licensing or directly from the patent owners, and therefore FDK AAC Codec
software may already be covered under those patent licenses when it is used for those licensed purposes only.
Commercially-licensed AAC software libraries, including floating-point versions with enhanced sound quality,
are also available from Fraunhofer. Users are encouraged to check the Fraunhofer website for additional
applications information and documentation.
2. COPYRIGHT LICENSE
Redistribution and use in source and binary forms, with or without modification, are permitted without
payment of copyright license fees provided that you satisfy the following conditions:
You must retain the complete text of this software license in redistributions of the FDK AAC Codec or
your modifications thereto in source code form.
You must retain the complete text of this software license in the documentation and/or other materials
provided with redistributions of the FDK AAC Codec or your modifications thereto in binary form.
You must make available free of charge copies of the complete source code of the FDK AAC Codec and your
modifications thereto to recipients of copies in binary form.
The name of Fraunhofer may not be used to endorse or promote products derived from this library without
prior written permission.
You may not charge copyright license fees for anyone to use, copy or distribute the FDK AAC Codec
software or your modifications thereto.
Your modified versions of the FDK AAC Codec must carry prominent notices stating that you changed the software
and the date of any change. For modified versions of the FDK AAC Codec, the term
"Fraunhofer FDK AAC Codec Library for Android" must be replaced by the term
"Third-Party Modified Version of the Fraunhofer FDK AAC Codec Library for Android."
3. NO PATENT LICENSE
NO EXPRESS OR IMPLIED LICENSES TO ANY PATENT CLAIMS, including without limitation the patents of Fraunhofer,
ARE GRANTED BY THIS SOFTWARE LICENSE. Fraunhofer provides no warranty of patent non-infringement with
respect to this software.
You may use this FDK AAC Codec software or modifications thereto only for purposes that are authorized
by appropriate patent licenses.
4. DISCLAIMER
This FDK AAC Codec software is provided by Fraunhofer on behalf of the copyright holders and contributors
"AS IS" and WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES, including but not limited to the implied warranties
of merchantability and fitness for a particular purpose. IN NO EVENT SHALL THE COPYRIGHT HOLDER OR
CONTRIBUTORS BE LIABLE for any direct, indirect, incidental, special, exemplary, or consequential damages,
including but not limited to procurement of substitute goods or services; loss of use, data, or profits,
or business interruption, however caused and on any theory of liability, whether in contract, strict
liability, or tort (including negligence), arising in any way out of the use of this software, even if
advised of the possibility of such damage.
