+GNU GENERAL PUBLIC LICENSE
+
+Version 2, June 1991
+
+Copyright (C) 1989, 1991 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.
+Preamble
+
+The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU
+General Public License is intended to guarantee your freedom to share and change free software--to make sure the
+software is free for all its users. This General Public License applies to most of the Free Software Foundation's
+software and to any other program whose authors commit to using it. (Some other Free Software Foundation software
+is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too.
+
+When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to
+make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish),
+that you receive source code or can get it if you want it, that you can change the software or use pieces of it in
+new free programs; and that you know you can do these things.
+
+To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to
+surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of
+the software, or if you modify it.
+
+For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients
+all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must
+show them these terms so they know their rights.
+
+We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you
+legal permission to copy, distribute and/or modify the software.
+
+Also, for each author's protection and ours, we want to make certain that everyone understands that there is no
+warranty for this free software. If the software is modified by someone else and passed on, we want its recipients
+to know that what they have is not the original, so that any problems introduced by others will not reflect on the
+original authors' reputations.
+
+Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that
+redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary.
+To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at
+all.
+
+The precise terms and conditions for copying, distribution and modification follow.
+
+TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+0. This License applies to any program or other work which contains a notice placed by the copyright holder saying
+it may be distributed under the terms of this General Public License. The "Program", below, refers to any such
+program or work, and a "work based on the Program" means either the Program or any derivative work under copyright
+law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or
+translated into another language. (Hereinafter, translation is included without limitation in the term
+"modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not covered by this License; they are outside its
+scope. The act of running the Program is not restricted, and the output from the Program is covered only if its
+contents constitute a work based on the Program (independent of having been made by running the Program). Whether
+that is true depends on what the Program does.
+
+1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium,
+provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and
+disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty
+protection in exchange for a fee.
+
+2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program,
+and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet
+all of these conditions:
+
+a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of
+any change.
+b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the
+Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this
+License.
+c) If the modified program normally reads commands interactively when run, you must cause it, when started running
+for such interactive use in the most ordinary way, to print or display an announcement including an appropriate
+copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users
+may redistribute the program under these conditions, and telling the user how to view a copy of this License.
+(Exception: if the Program itself is interactive but does not normally print such an announcement, your work based
+on the Program is not required to print an announcement.)
+These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived
+from the Program, and can be reasonably considered independent and separate works in themselves, then this License,
+and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute
+the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on
+the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and
+every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you;
+rather, the intent is to exercise the right to control the distribution of derivative or collective works based on
+the Program.
+
+In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the
+Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this
+License.
+
+3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable
+form under the terms of Sections 1 and 2 above provided that you also do one of the following:
+
+a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the
+terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
+b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more
+than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding
+source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software
+interchange; or,
+c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This
+alternative is allowed only for noncommercial distribution and only if you received the program in object code or
+executable form with such an offer, in accord with Subsection b above.)
+The source code for a work means the preferred form of the work for making modifications to it. For an executable
+work, complete source code means all the source code for all modules it contains, plus any associated interface
+definition files, plus the scripts used to control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include anything that is normally distributed (in either
+source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the
+executable runs, unless that component itself accompanies the executable.
+
+If distribution of executable or object code is made by offering access to copy from a designated place, then
+offering equivalent access to copy the source code from the same place counts as distribution of the source code,
+even though third parties are not compelled to copy the source along with the object code.
+
+4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License.
+Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically
+terminate your rights under this License. However, parties who have received copies, or rights, from you under this
+License will not have their licenses terminated so long as such parties remain in full compliance.
+
+5. You are not required to accept this License, since you have not signed it. However, nothing else grants you
+permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you
+do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program),
+you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or
+modifying the Program or works based on it.
+
+6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives
+a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions.
+You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not
+responsible for enforcing compliance by third parties to this License.
+
+7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited
+to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict
+the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute
+so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a
+consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free
+redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way
+you could satisfy both it and this License would be to refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of
+the section is intended to apply and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any patents or other property right claims or to
+contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free
+software distribution system, which is implemented by public license practices. Many people have made generous
+contributions to the wide range of software distributed through that system in reliance on consistent application of
+that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other
+system and a licensee cannot impose that choice.
+
+This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
+
+8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by
+copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit
+geographical distribution limitation excluding those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this
+License.
+
+9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to
+time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new
+problems or concerns.
+
+Each version is given a distinguishing version number. If the Program specifies a version number of this License
+which applies to it and "any later version", you have the option of following the terms and conditions either of
+that version or of any later version published by the Free Software Foundation. If the Program does not specify a
+version number of this License, you may choose any version ever published by the Free Software Foundation.
+
+10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are
+different, write to the author to ask for permission. For software which is copyrighted by the Free Software
+Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be
+guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the
+sharing and reuse of software generally.
+
+NO WARRANTY
+
+11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED
+BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
+PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
+PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
+SERVICING, REPAIR OR CORRECTION.
+
+12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER
+PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING
+ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
+(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
+BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Programs
+
+If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to
+achieve this is to make it free software which everyone can redistribute and change under these terms.
+
+To do so, attach the following notices to the program. It is safest to attach them to the start of each source file
+to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and
+a pointer to where the full notice is found.
+
+one line to give the program's name and an idea of what it does.

+
+This General Public License does not permit incorporating your program into proprietary programs. If your program is
+a subroutine library, you may consider it more useful to permit linking proprietary applications with the library.
+If this is what you want to do, use the GNU Lesser General Public License instead of this License.

+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.
