  Everyone  is permitted to copy and distribute verbatim copies
  of this  license document, but changing it is not allowed.
[This is the first released version of the Lesser  GPL.  It also counts
  as the  successor of the GNU Library Public License, version 2, hence
  the  version number 2.1.]
Preamble
  The  licenses for most software are designed to take away your
  freedom to share and change it.  By contrast, the GNU General Public
  Licenses are intended to guarantee your freedom  to share and change
  free software--to make sure the software is free  for all its users.
  This  license, the Lesser General Public License, applies to some
  specially designated software packages--typically  libraries--of the
  Free Software Foundation and other authors who  decide to use it.  You
  can use it too, but we suggest you first think  carefully about whether
  this license or the ordinary General Public  License is the better
  strategy to use in any particular case, based on  the explanations below.
  When we  speak of free software, we are referring to freedom of use,
  not price.   Our General Public Licenses are designed to make sure that
  you have the freedom to distribute copies of free  software (and charge
  for this service if you wish); that you receive  source code or can get
  it if you want it; that you can change the  software and use pieces of
  it in new free programs; and that you are informed  that you can do
  these things.
  To  protect your rights, we need to make restrictions that forbid
  distributors to deny you these rights or to ask  you to surrender these
  rights.   These restrictions translate to certain responsibilities for
  you if you distribute copies of the library or if  you modify it.
  For  example, if you distribute copies of the library, whether gratis
  or for a fee, you must give the recipients all  the rights that we gave
  you.  You  must make sure that they, too, receive or can get the source
  code.  If  you link other code with the library, you must provide
  complete object files to the recipients, so that  they can relink them
  with the library after making changes to the  library and recompiling
  it.  And  you must show them these terms so they know their rights.
  We  protect your rights with a two-step method: (1) we copyright the
  library, and (2) we offer you this license, which  gives you legal
  permission to copy, distribute and/or modify the  library.
  To  protect each distributor, we want to make it very clear that
  there is no warranty for the free library.  Also, if the library is
  modified by someone else and passed on, the  recipients should know
  that what they have is not the original version,  so that the original
  author's reputation will not be affected by  problems that might be
  introduced by others.
  Finally,  software patents pose a constant threat to the existence of
  any free program.   We wish to make sure that a company cannot
  effectively restrict the users of a free program  by obtaining a
  restrictive license from a patent holder.  Therefore, we insist that
  any patent license obtained for a version of the  library must be
  consistent with the full freedom of use specified  in this license.
  Most GNU  software, including some libraries, is covered by the
  ordinary GNU General Public License.  This license, the GNU Lesser
  General Public License, applies to certain  designated libraries, and
  is quite different from the ordinary General  Public License.  We use
  this license for certain libraries in order to  permit linking those
  libraries into non-free programs.
  When a  program is linked with a library, whether statically or using
  a shared library, the combination of the two is  legally speaking a
  combined work, a derivative of the original  library.  The ordinary
  General Public License therefore permits such  linking only if the
  entire combination fits its criteria of  freedom.  The Lesser General
  Public License permits more lax criteria for  linking other code with
  the library.
  We call  this license the "Lesser" General Public License because it
  does Less to protect the user's freedom than the  ordinary General
  Public License.   It also provides other free software developers Less
  of an advantage over competing non-free programs.  These disadvantages
  are the reason we use the ordinary General Public  License for many
  libraries.   However, the Lesser license provides advantages in certain
  special circumstances.
  For  example, on rare occasions, there may be a special need to
  encourage the widest possible use of a certain  library, so that it becomes
  a de-facto standard.  To achieve this, non-free programs must be
  allowed to use the library.  A more frequent case is that a free
  library does the same job as widely used non-free  libraries.  In this
  case, there is little to gain by limiting the  free library to free
  software only, so we use the Lesser General  Public License.
  In other  cases, permission to use a particular library in non-free
  programs enables a greater number of people to  use a large body of
  free software.   For example, permission to use the GNU C Library in
  non-free programs enables many more people to use  the whole GNU
  operating system, as well as its variant, the  GNU/Linux operating
  system.
  Although  the Lesser General Public License is Less protective of the
  users' freedom, it does ensure that the user of a  program that is
  linked with the Library has the freedom and the  wherewithal to run
  that program using a modified version of the  Library.
  The  precise terms and conditions for copying, distribution and
  modification follow.  Pay close attention to the difference between  a
  "work based on the library" and a  "work that uses the library".   The
  former contains code derived from the library,  whereas the latter must
  be combined with the library in order to run.
                   GNU LESSER GENERAL PUBLIC LICENSE
  TERMS  AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
  0. This  License Agreement applies to any software library or other
  program which contains a notice placed by the  copyright holder or
  other authorized party saying it may be  distributed under the terms of
  this Lesser General Public License (also called  "this License").
  Each licensee is addressed as "you".
  A  "library" means a collection of software functions and/or data
  prepared so as to be conveniently linked with  application programs
  (which use some of those functions and data) to  form executables.
  The  "Library", below, refers to any such software library or work
  which has been distributed under these  terms.  A "work based on the
  Library" means either the Library or any  derivative work under
  copyright law: that is to say, a work containing  the Library or a
  portion of it, either verbatim or with  modifications and/or translated
  straightforwardly into another language.  (Hereinafter, translation is
  included without limitation in the term  "modification".)
   "Source code" for a work means the preferred form of the work  for
  making modifications to it.  For a library, complete source code means
  all the source code for all modules it contains,  plus any associated
  interface definition files, plus the scripts used  to control compilation
  and installation of the library.
   Activities other than copying, distribution and modification are not
  covered by this License; they are outside its  scope.  The act of
  running a program using the Library is not  restricted, and output from
  such a program is covered only if its contents  constitute a work based
  on the Library (independent of the use of the  Library in a tool for
  writing it).   Whether that is true depends on what the Library does
  and what the program that uses the Library does.
  1. You  may copy and distribute verbatim copies of the Library's
  complete source code as you receive it, in any  medium, provided that
  you conspicuously and appropriately publish on  each copy an
  appropriate copyright notice and disclaimer of  warranty; keep intact
  all the notices that refer to this License and to  the absence of any
  warranty; and distribute a copy of this License  along with the
  Library.
  You may  charge a fee for the physical act of transferring a copy,
  and you may at your option offer warranty  protection in exchange for a
  fee.
  2. You  may modify your copy or copies of the Library or any portion
  of it, thus forming a work based on the Library,  and copy and
  distribute such modifications or work under the  terms of Section 1
  above, provided that you also meet all of these  conditions:
a) The modified work must itself be a software library.
    b) You  must cause the files modified to carry prominent notices
  stating  that you changed the files and the date of any change.
    c) You  must cause the whole of the work to be licensed at no
  charge  to all third parties under the terms of this License.
    d) If a  facility in the modified Library refers to a function or a
  table  of data to be supplied by an application program that uses
  the  facility, other than as an argument passed when the facility
  is  invoked, then you must make a good faith effort to ensure that,
  in the  event an application does not supply such function or
  table,  the facility still operates, and performs whatever part of
  its  purpose remains meaningful.
    (For  example, a function in a library to compute square roots has
  a  purpose that is entirely well-defined independent of the
  application.  Therefore,  Subsection 2d requires that any
  application-supplied function or table used by this function must
  be  optional: if the application does not supply it, the square
  root  function must still compute square roots.)
These requirements apply to the modified work as  a whole.  If
  identifiable sections of that work are not  derived from the Library,
  and can be reasonably considered independent and  separate works in
  themselves, then this License, and its terms, do  not apply to those
  sections when you distribute them as separate  works.  But when you
  distribute the same sections as part of a whole  which is a work based
  on the Library, the distribution of the whole  must be on the terms of
  this License, whose permissions for other  licensees extend to the
  entire whole, and thus to each and every part  regardless of who wrote
  it.
Thus, it is not the intent of this section to  claim rights or contest
  your rights to work written entirely by you;  rather, the intent is to
  exercise the right to control the distribution of  derivative or
  collective works based on the Library.
In addition, mere aggregation of another work not  based on the Library
  with the Library (or with a work based on the  Library) on a volume of
  a storage or distribution medium does not bring  the other work under
  the scope of this License.
  3. You  may opt to apply the terms of the ordinary GNU General Public
  License instead of this License to a given copy  of the Library.  To do
  this, you must alter all the notices that refer  to this License, so
  that they refer to the ordinary GNU General  Public License, version 2,
  instead of to this License.  (If a newer version than version 2 of the
  ordinary GNU General Public License has appeared,  then you can specify
  that version instead if you wish.)  Do not make any other change in
  these notices.
  Once this  change is made in a given copy, it is irreversible for
  that copy, so the ordinary GNU General Public  License applies to all
  subsequent copies and derivative works made from  that copy.
  This  option is useful when you wish to copy part of the code of
  the Library into a program that is not a library.
  4. You  may copy and distribute the Library (or a portion or
  derivative of it, under Section 2) in object code  or executable form
  under the terms of Sections 1 and 2 above  provided that you accompany
  it with the complete corresponding machine-readable  source code, which
  must be distributed under the terms of Sections 1  and 2 above on a
  medium customarily used for software interchange.
  If  distribution of object code is made by offering access to copy
  from a designated place, then offering equivalent  access to copy the
  source code from the same place satisfies the  requirement to
  distribute the source code, even though third  parties are not
  compelled to copy the source along with the  object code.
  5. A  program that contains no derivative of any portion of the
  Library, but is designed to work with the Library  by being compiled or
  linked with it, is called a "work that uses  the Library".  Such a
  work, in isolation, is not a derivative work of  the Library, and
  therefore falls outside the scope of this  License.
  However,  linking a "work that uses the Library" with the Library
  creates an executable that is a derivative of the  Library (because it
  contains portions of the Library), rather than a  "work that uses the
  library".   The executable is therefore covered by this License.
  Section 6 states terms for distribution of such  executables.
  When a  "work that uses the Library" uses material from a header file
  that is part of the Library, the object code for  the work may be a
  derivative work of the Library even though the  source code is not.
  Whether this is true is especially significant if  the work can be
  linked without the Library, or if the work is  itself a library.  The
  threshold for this to be true is not precisely  defined by law.
  If such  an object file uses only numerical parameters, data
  structure layouts and accessors, and small macros  and small inline
  functions (ten lines or less in length), then the  use of the object
  file is unrestricted, regardless of whether it is  legally a derivative
  work.   (Executables containing this object code plus portions of the
  Library will still fall under Section 6.)
   Otherwise, if the work is a derivative of the Library, you may
  distribute the object code for the work under the  terms of Section 6.
  Any executables containing that work also fall  under Section 6,
  whether or not they are linked directly with the  Library itself.
  6. As an  exception to the Sections above, you may also combine or
  link a "work that uses the Library"  with the Library to produce a
  work containing portions of the Library, and  distribute that work
  under terms of your choice, provided that the  terms permit
  modification of the work for the customer's own  use and reverse
  engineering for debugging such modifications.
  You must  give prominent notice with each copy of the work that the
  Library is used in it and that the Library and  its use are covered by
  this License.   You must supply a copy of this License.   If the work
  during execution displays copyright notices, you  must include the
  copyright notice for the Library among them, as  well as a reference
  directing the user to the copy of this  License.  Also, you must do one
  of these things:
    a)  Accompany the work with the complete corresponding
  machine-readable source code for the Library  including whatever
  changes  were used in the work (which must be distributed under
  Sections 1 and 2 above); and, if the work is an executable linked
  with  the Library, with the complete machine-readable "work that
  uses  the Library", as object code and/or source code, so that the
  user  can modify the Library and then relink to produce a modified
  executable containing the modified Library.  (It is understood
  that  the user who changes the contents of definitions files in the
  Library  will not necessarily be able to recompile the application
  to use  the modified definitions.)
    b) Use  a suitable shared library mechanism for linking with the
  Library.  A suitable mechanism is  one that (1) uses at run time a
  copy of  the library already present on the user's computer system,
  rather  than copying library functions into the executable, and (2)
  will  operate properly with a modified version of the library, if
  the  user installs one, as long as the modified version is
  interface-compatible with the version that the work was made with.
    c)  Accompany the work with a written offer, valid for at
  least  three years, to give the same user the materials
  specified in Subsection 6a, above, for a charge no more
  than  the cost of performing this distribution.
    d) If  distribution of the work is made by offering access to copy
  from a  designated place, offer equivalent access to copy the above
  specified materials from the same place.
    e)  Verify that the user has already received a copy of these
  materials or that you have already sent this user a copy.
  For an executable,  the required form of the "work that uses the
  Library" must include any data and utility  programs needed for
  reproducing the executable from it.  However, as a special exception,
  the materials to be distributed need not include  anything that is
  normally distributed (in either source or binary  form) with the major
  components (compiler, kernel, and so on) of the  operating system on
  which the executable runs, unless that component  itself accompanies
  the executable.
  It may  happen that this requirement contradicts the license
  restrictions of other proprietary libraries that  do not normally
  accompany the operating system.  Such a contradiction means you cannot
  use both them and the Library together in an  executable that you
  distribute.
  7. You  may place library facilities that are a work based on the
  Library side-by-side in a single library together  with other library
  facilities not covered by this License, and  distribute such a combined
  library, provided that the separate distribution  of the work based on
  the Library and of the other library facilities  is otherwise
  permitted, and provided that you do these two  things:
    a)  Accompany the combined library with a copy of the same work
  based  on the Library, uncombined with any other library
  facilities.  This must be  distributed under the terms of the
  Sections above.
    b) Give  prominent notice with the combined library of the fact
  that  part of it is a work based on the Library, and explaining
  where  to find the accompanying uncombined form of the same work.
  8. You  may not copy, modify, sublicense, link with, or distribute
  the Library except as expressly provided under  this License.  Any
  attempt otherwise to copy, modify, sublicense,  link with, or
  distribute the Library is void, and will  automatically terminate your
  rights under this License.  However, parties who have received copies,
  or rights, from you under this License will not  have their licenses
  terminated so long as such parties remain in full  compliance.
  9. You  are not required to accept this License, since you have not
  signed it.   However, nothing else grants you permission to modify or
  distribute the Library or its derivative  works.  These actions are
  prohibited by law if you do not accept this  License.  Therefore, by
  modifying or distributing the Library (or any  work based on the
  Library), you indicate your acceptance of this License  to do so, and
  all its terms and conditions for copying,  distributing or modifying
  the Library or works based on it.
  10. Each  time you redistribute the Library (or any work based on the
  Library), the recipient automatically receives a  license from the
  original licensor to copy, distribute, link with  or modify the Library
  subject to these terms and conditions.  You may not impose any further
  restrictions on the recipients' exercise of the  rights granted herein.
  You are not responsible for enforcing compliance  by third parties with
  this License.
  11. If,  as a consequence of a court judgment or allegation of patent
  infringement or for any other reason (not limited  to patent issues),
  conditions are imposed on you (whether by court  order, agreement or
  otherwise) that contradict the conditions of this  License, they do not
  excuse you from the conditions of this  License.  If you cannot
  distribute so as to satisfy simultaneously your  obligations under this
  License and any other pertinent obligations, then  as a consequence you
  may not distribute the Library at all.  For example, if a patent
  license would not permit royalty-free redistribution  of the Library by
  all those who receive copies directly or  indirectly through you, then
  the only way you could satisfy both it and this  License would be to
  refrain entirely from distribution of the  Library.
If any portion of this section is held invalid or  unenforceable under any
  particular circumstance, the balance of the  section is intended to apply,
  and the section as a whole is intended to apply  in other circumstances.
It is not the purpose of this section to induce  you to infringe any
  patents or other property right claims or to  contest validity of any
  such claims; this section has the sole purpose of  protecting the
  integrity of the free software distribution  system which is
  implemented by public license practices.  Many people have made
  generous contributions to the wide range of  software distributed
  through that system in reliance on consistent  application of that
  system; it is up to the author/donor to decide if  he or she is willing
  to distribute software through any other system and  a licensee cannot
  impose that choice.
This section is intended to make thoroughly clear  what is believed to
  be a consequence of the rest of this License.
  12. If  the distribution and/or use of the Library is restricted in
  certain countries either by patents or by  copyrighted interfaces, the
  original copyright holder who places the Library  under this License may add
  an explicit geographical distribution limitation  excluding those countries,
  so that distribution is permitted only in or  among countries not thus
  excluded.   In such case, this License incorporates the limitation as if
  written in the body of this License.
  13. The  Free Software Foundation may publish revised and/or new
  versions of the Lesser General Public License  from time to time.
  Such new versions will be similar in spirit to  the present version,
  but may differ in detail to address new problems  or concerns.
Each version is given a distinguishing version  number.  If the Library
  specifies a version number of this License which  applies to it and
  "any later version", you have the  option of following the terms and
  conditions either of that version or of any later  version published by
  the Free Software Foundation.  If the Library does not specify a
  license version number, you may choose any  version ever published by
  the Free Software Foundation.
  14. If  you wish to incorporate parts of the Library into other free
  programs whose distribution conditions are  incompatible with these,
  write to the author to ask for permission.  For software which is
  copyrighted by the Free Software Foundation,  write to the Free
  Software Foundation; we sometimes make exceptions  for this.  Our
  decision will be guided by the two goals of  preserving the free status
  of all derivatives of our free software and of  promoting the sharing
  and reuse of software generally.
NO WARRANTY
  15.  BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
  WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED  BY APPLICABLE LAW.
  EXCEPT WHEN OTHERWISE STATED IN WRITING THE  COPYRIGHT HOLDERS AND/OR
  OTHER PARTIES PROVIDE THE LIBRARY "AS  IS" WITHOUT WARRANTY OF ANY
  KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT  NOT LIMITED TO, THE
  IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS  FOR A PARTICULAR
  PURPOSE.   THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
  LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU  ASSUME
  THE COST OF ALL NECESSARY SERVICING, REPAIR OR  CORRECTION.
  16. IN NO  EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
  WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER  PARTY WHO MAY MODIFY
  AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED  ABOVE, BE LIABLE TO YOU
  FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,  INCIDENTAL OR
  CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR  INABILITY TO USE THE
  LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF  DATA OR DATA BEING
  RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR  THIRD PARTIES OR A
  FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER  SOFTWARE), EVEN IF
  SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF  THE POSSIBILITY OF SUCH
  DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
  If you  develop a new library, and you want it to be of the greatest
  possible use to the public, we recommend making  it free software that
  everyone can redistribute and change.  You can do so by permitting
  redistribution under these terms (or,  alternatively, under the terms of the
  ordinary General Public License).
  To apply  these terms, attach the following notices to the library.  It is
  safest to attach them to the start of each source  file to most effectively
  convey the exclusion of warranty; and each file  should have at least the
  "copyright" line and a pointer to where  the full notice is found.
    <one  line to give the library's name and a brief idea of what it does.>
  Copyright (C) <year>   <name of author>
    This  library is free software; you can redistribute it and/or
  modify  it under the terms of the GNU Lesser General Public
  License  as published by the Free Software Foundation; either
  version  2.1 of the License, or (at your option) any later version.
    This  library is distributed in the hope that it will be useful,
  but  WITHOUT ANY WARRANTY; without even the implied warranty of
  MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
  Lesser  General Public License for more details.
    You  should have received a copy of the GNU Lesser General Public
  License  along with this library; if not, write to the Free Software
  Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA  02110-1301   USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as  a programmer) or your
  school, if any, to sign a "copyright  disclaimer" for the library, if
  necessary.   Here is a sample; alter the names:
  Yoyodyne,  Inc., hereby disclaims all copyright interest in the
  library  `Frob' (a library for tweaking knobs) written by James Random Hacker.
