+

+     
+     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 library GPL.  It is
+      numbered 2 because it goes with version 2 of the ordinary GPL.]
+
+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 Library General Public License, applies to some
+specially designated Free Software Foundation software, and to any
+other libraries whose authors decide to use it.  You can use it for
+your libraries, 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 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 a program 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.
+
+   Our method of protecting your rights has two steps: (1) copyright
+the library, and (2) offer you this license which gives you legal
+permission to copy, distribute and/or modify the library.
+
+   Also, for each distributor's protection, we want to make certain
+that everyone understands that there is no warranty for this free
+library.  If the library is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original
+version, 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 companies distributing free
+software will individually obtain patent licenses, thus in effect
+transforming the program into proprietary software.  To prevent this,
+we have made it clear that any patent must be licensed for everyone's
+free use or not licensed at all.
+
+   Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License, which was designed for utility
+programs.  This license, the GNU Library General Public License,
+applies to certain designated libraries.  This license is quite
+different from the ordinary one; be sure to read it in full, and don't
+assume that anything in it is the same as in the ordinary license.
+
+   The reason we have a separate public license for some libraries is
+that they blur the distinction we usually make between modifying or
+adding to a program and simply using it.  Linking a program with a
+library, without changing the library, is in some sense simply using
+the library, and is analogous to running a utility program or
+application program.  However, in a textual and legal sense, the linked
+executable is a combined work, a derivative of the original library,
+and the ordinary General Public License treats it as such.
+
+   Because of this blurred distinction, using the ordinary General
+Public License for libraries did not effectively promote software
+sharing, because most developers did not use the libraries.  We
+concluded that weaker conditions might promote sharing better.
+
+   However, unrestricted linking of non-free programs would deprive the
+users of those programs of all benefit from the free status of the
+libraries themselves.  This Library General Public License is intended
+to permit developers of non-free programs to use free libraries, while
+preserving your freedom as a user of such programs to change the free
+libraries that are incorporated in them.  (We have not seen how to
+achieve this as regards changes in header files, but we have achieved
+it as regards changes in the actual functions of the Library.)  The
+hope is that this will lead to faster development of free libraries.
+
+   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, while the latter only
+works together with the library.
+
+   Note that it is possible for a library to be covered by the ordinary
+General Public License rather than by this special one.
+
+    TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library which
+     contains a notice placed by the copyright holder or other
+     authorized party saying it may be distributed under the terms of
+     this Library 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 compile 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. 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.
+
+       c. 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.
+
+       d. 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 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.
+
+     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 to 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 Library General Public License from time to time.
+     Such new versions will be similar in spirit to the present version,
+     but may differ in detail to address new problems or concerns.
+
+     Each version is given a distinguishing version number.  If the
+     Library specifies a version number of this License which applies
+     to it and "any later version", you have the option of following
+     the terms and conditions either of that version or of any later
+     version published by the Free Software Foundation.  If the Library
+     does not specify a license version number, you may choose any
+     version ever published by the Free Software Foundation.
+
+ 14. If you wish to incorporate parts of the Library into other free
+     programs whose distribution conditions are incompatible with these,
+     write to the author to ask for permission.  For software which is
+     copyrighted by the Free Software Foundation, write to the Free
+     Software Foundation; we sometimes make exceptions for this.  Our
+     decision will be guided by the two goals of preserving the free
+     status of all derivatives of our free software and of promoting
+     the sharing and reuse of software generally.
+
+                                NO WARRANTY
+
+ 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+     WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE
+     LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+     HOLDERS AND/OR OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT
+     WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT
+     NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
+     FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS TO THE
+     QUALITY AND PERFORMANCE OF THE LIBRARY IS WITH YOU.  SHOULD THE
+     LIBRARY PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY
+     SERVICING, REPAIR OR CORRECTION.
+
+ 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+     WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
+     MODIFY AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE
+     LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL,
+     INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR
+     INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF
+     DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU
+     OR THIRD PARTIES OR A FAILURE OF THE LIBRARY TO OPERATE WITH ANY
+     OTHER SOFTWARE), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
+
+                      END OF TERMS AND CONDITIONS
+
+How to Apply These Terms to Your New Libraries
+==============================================
+
+   If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms of
+the ordinary General Public License).
+
+   To apply these terms, attach the following notices to the library.
+It is safest to attach them to the start of each source file to most
+effectively convey the exclusion of warranty; and each file should have
+at least the "copyright" line and a pointer to where the full notice is
+found.
+
+     ONE LINE TO GIVE THE LIBRARY'S NAME AND AN IDEA OF WHAT IT DOES.
+     Copyright (C) YEAR  NAME OF AUTHOR
+     
+     This library is free software; you can redistribute it and/or modify it
+     under the terms of the GNU Library General Public License as published
+     by the Free Software Foundation; either version 2 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
+     Library General Public License for more details.
+     
+     You should have received a copy of the GNU General Public License along
+     with this program; if not, write to the Free Software Foundation, Inc.,
+     59 Temple Place, Suite 330, Boston, MA 02111-1307, 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
