+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+-
+- This version of the GNU Lesser General Public License incorporates
+-the terms and conditions of version 3 of the GNU General Public
+-License, supplemented by the additional permissions listed below.
+-
+- 0. Additional Definitions.
+-
+- As used herein, "this License" refers to version 3 of the GNU Lesser
+-General Public License, and the "GNU GPL" refers to version 3 of the GNU
+-General Public License.
+-
+- "The Library" refers to a covered work governed by this License,
+-other than an Application or a Combined Work as defined below.
+-
+- An "Application" is any work that makes use of an interface provided
+-by the Library, but which is not otherwise based on the Library.
+-Defining a subclass of a class defined by the Library is deemed a mode
+-of using an interface provided by the Library.
+-
+- A "Combined Work" is a work produced by combining or linking an
+-Application with the Library. The particular version of the Library
+-with which the Combined Work was made is also called the "Linked
+-Version".
+-
+- The "Minimal Corresponding Source" for a Combined Work means the
+-Corresponding Source for the Combined Work, excluding any source code
+-for portions of the Combined Work that, considered in isolation, are
+-based on the Application, and not on the Linked Version.
+-
+- The "Corresponding Application Code" for a Combined Work means the
+-object code and/or source code for the Application, including any data
+-and utility programs needed for reproducing the Combined Work from the
+-Application, but excluding the System Libraries of the Combined Work.
+-
+- 1. Exception to Section 3 of the GNU GPL.
+-
+- You may convey a covered work under sections 3 and 4 of this License
+-without being bound by section 3 of the GNU GPL.
+-
+- 2. Conveying Modified Versions.
+-
+- If you modify a copy of the Library, and, in your modifications, a
+-facility refers to a function or data to be supplied by an Application
+-that uses the facility (other than as an argument passed when the
+-facility is invoked), then you may convey a copy of the modified
+-version:
+-
+- a) under this License, provided that you make a good faith effort to
+- ensure that, in the event an Application does not supply the
+- function or data, the facility still operates, and performs
+- whatever part of its purpose remains meaningful, or
+-
+- b) under the GNU GPL, with none of the additional permissions of
+- this License applicable to that copy.
+-
+- 3. Object Code Incorporating Material from Library Header Files.
+-
+- The object code form of an Application may incorporate material from
+-a header file that is part of the Library. You may convey such object
+-code under terms of your choice, provided that, if the incorporated
+-material is not limited to numerical parameters, data structure
+-layouts and accessors, or small macros, inline functions and templates
+-(ten or fewer lines in length), you do both of the following:
+-
+- a) Give prominent notice with each copy of the object code that the
+- Library is used in it and that the Library and its use are
+- covered by this License.
+-
+- b) Accompany the object code with a copy of the GNU GPL and this license
+- document.
+-
+- 4. Combined Works.
+-
+- You may convey a Combined Work under terms of your choice that,
+-taken together, effectively do not restrict modification of the
+-portions of the Library contained in the Combined Work and reverse
+-engineering for debugging such modifications, if you also do each of
+-the following:
+-
+- a) Give prominent notice with each copy of the Combined Work that
+- the Library is used in it and that the Library and its use are
+- covered by this License.
+-
+- b) Accompany the Combined Work with a copy of the GNU GPL and this license
+- document.
+-
+- c) For a Combined Work that displays copyright notices during
+- execution, include the copyright notice for the Library among
+- these notices, as well as a reference directing the user to the
+- copies of the GNU GPL and this license document.
+-
+- d) Do one of the following:
+-
+- 0) Convey the Minimal Corresponding Source under the terms of this
+- License, and the Corresponding Application Code in a form
+- suitable for, and under terms that permit, the user to
+- recombine or relink the Application with a modified version of
+- the Linked Version to produce a modified Combined Work, in the
+- manner specified by section 6 of the GNU GPL for conveying
+- Corresponding Source.
+-
+- 1) Use a suitable shared library mechanism for linking with the
+- Library. A suitable mechanism is one that (a) uses at run time
+- a copy of the Library already present on the user's computer
+- system, and (b) will operate properly with a modified version
+- of the Library that is interface-compatible with the Linked
+- Version.
+-
+- e) Provide Installation Information, but only if you would otherwise
+- be required to provide such information under section 6 of the
+- GNU GPL, and only to the extent that such information is
+- necessary to install and execute a modified version of the
+- Combined Work produced by recombining or relinking the
+- Application with a modified version of the Linked Version. (If
+- you use option 4d0, the Installation Information must accompany
+- the Minimal Corresponding Source and Corresponding Application
+- Code. If you use option 4d1, you must provide the Installation
+- Information in the manner specified by section 6 of the GNU GPL
+- for conveying Corresponding Source.)
+-
+- 5. Combined Libraries.
+-
+- You may place library facilities that are a work based on the
+-Library side by side in a single library together with other library
+-facilities that are not Applications and are not covered by this
+-License, and convey such a combined library under terms of your
+-choice, if you do both of the following:
+-
+- a) Accompany the combined library with a copy of the same work based
+- on the Library, uncombined with any other library facilities,
+- conveyed under the terms of this License.
+-
+- b) Give prominent notice with the combined library that part of it
+- is a work based on the Library, and explaining where to find the
+- accompanying uncombined form of the same work.
+-
+- 6. Revised Versions of the GNU Lesser General Public License.
+-
+- The Free Software Foundation may publish revised and/or new versions
+-of the GNU Lesser General Public License from time to time. Such new
+-versions will be similar in spirit to the present version, but may
+-differ in detail to address new problems or concerns.
+-
+- Each version is given a distinguishing version number. If the
+-Library as you received it specifies that a certain numbered version
+-of the GNU Lesser General Public License "or any later version"
+-applies to it, you have the option of following the terms and
+-conditions either of that published version or of any later version
+-published by the Free Software Foundation. If the Library as you
+-received it does not specify a version number of the GNU Lesser
+-General Public License, you may choose any version of the GNU Lesser
+-General Public License ever published by the Free Software Foundation.
+-
+- If the Library as you received it specifies that a proxy can decide
+-whether future versions of the GNU Lesser General Public License shall
+-apply, that proxy's public statement of acceptance of any version is
+-permanent authorization for you to choose that version for the
++[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.
++
++ <signature of Ty Coon>, 1 April 1990
++ Ty Coon, President of Vice
++
++That's all there is to it!
