-                       Version 2.1, February 1999
-
- Copyright (C) 1991, 1999 Free Software Foundation, Inc.
-	51 Franklin St, 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 informed 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
-
-  0. 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 Section 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 library 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 of 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 St, 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.
-
-  <signature of Ty Coon>, 1 April 1990
-  Ty Coon, President of Vice

-That's all there is to it!

+
+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 library GPL. It is numbered 2 because
+it goes with version 2 of the ordinary GPL.]
+
+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 Library General Public License, applies to some specially
+designated Free Software Foundation software, and to any other libraries whose
+authors decide to use it. You can use it for your libraries, 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 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
+a program 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.
+
+Our method of protecting your rights has two steps: (1) copyright the library,
+and (2) offer you this license which gives you legal permission to copy, distribute
+and/or modify the library.
+
+Also, for each distributor's protection, we want to make certain that everyone
+understands that there is no warranty for this free library. If the library
+is modified by someone else and passed on, we want its recipients to know
+that what they have is not the original version, 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 companies distributing free software will individually
+obtain patent licenses, thus in effect transforming the program into proprietary
+software. To prevent this, we have made it clear that any patent must be licensed
+for everyone's free use or not licensed at all.
+
+Most GNU software, including some libraries, is covered by the ordinary GNU
+General Public License, which was designed for utility programs. This license,
+the GNU Library General Public License, applies to certain designated libraries.
+This license is quite different from the ordinary one; be sure to read it
+in full, and don't assume that anything in it is the same as in the ordinary
+license.
+
+The reason we have a separate public license for some libraries is that they
+blur the distinction we usually make between modifying or adding to a program
+and simply using it. Linking a program with a library, without changing the
+library, is in some sense simply using the library, and is analogous to running
+a utility program or application program. However, in a textual and legal
+sense, the linked executable is a combined work, a derivative of the original
+library, and the ordinary General Public License treats it as such.
+
+Because of this blurred distinction, using the ordinary General Public License
+for libraries did not effectively promote software sharing, because most developers
+did not use the libraries. We concluded that weaker conditions might promote
+sharing better.
+
+However, unrestricted linking of non-free programs would deprive the users
+of those programs of all benefit from the free status of the libraries themselves.
+This Library General Public License is intended to permit developers of non-free
+programs to use free libraries, while preserving your freedom as a user of
+such programs to change the free libraries that are incorporated in them.
+(We have not seen how to achieve this as regards changes in header files,
+but we have achieved it as regards changes in the actual functions of the
+Library.) The hope is that this will lead to faster development of free libraries.
+
+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, while the latter only works together with the library.
+
+Note that it is possible for a library to be covered by the ordinary General
+Public License rather than by this special one.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License Agreement applies to any software library which contains a
+notice placed by the copyright holder or other authorized party saying it
+may be distributed under the terms of this Library 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 Section 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 compile 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) 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.
+
+c) 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.
+
+d) 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 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.
+
+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 library 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 to 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 of 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 Library 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 an 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 Library General Public License as published by the Free
+Software Foundation; either version 2 of the License, or (at your option)

+
+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 Library General Public License for more

+You should have received a copy of the GNU Library General Public License
+along with this library; if not, write to the Free Software Foundation, Inc.,
+51 Franklin St, 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

+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 informed 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.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. 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 Section 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 library 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 of 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 an 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

+on how to contact you by electronic and paper mail.

+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 informed 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.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. 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 Section 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 library 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 of 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 an 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

+
+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

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