+-                  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.
+-
+-                  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 Street, Fifth Floor, Boston, MA  02110-1301  USA
+-
+-Also add information on how to contact you by electronic and paper mail.
+-
+-You should also get your employer (if you work as a programmer) or your
+-school, if any, to sign a "copyright disclaimer" for the library, if
+-necessary.  Here is a sample; alter the names:
+-
+-  Yoyodyne, Inc., hereby disclaims all copyright interest in the
+-  library `Frob' (a library for tweaking knobs) written by James Random Hacker.
