-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 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:
