+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.]
+
+@sp 1
+@center Preamble
+@sp 1
+
+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.

+@center GNU LESSER GENERAL PUBLIC LICENSE
+@center TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+@enumerate 0
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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:
+
+@enumerate a
+
+@item
+The modified work must itself be a software library.
+
+@sp 1
+@item
+You must cause the files modified to carry prominent notices stating
+that you changed the files and the date of any change.
+
+@sp 1
+@item
+You must cause the whole of the work to be licensed at no charge to all
+third parties under the terms of this License.
+
+@sp 1
+@item
+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.)
+
+@end enumerate
+
+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.
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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:
+
+@enumerate a
+
+@sp 1
+@item
+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.)
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+Verify that the user has already received a copy of these materials or
+that you have already sent this user a copy.
+
+@end enumerate
+
+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.
+
+@sp 1
+@item
+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:
+
+@enumerate a
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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.
+
+@end enumerate
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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.
+
+@sp 1
+@item
+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.

+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and ``any

+@center 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.
