 * 		  GNU LESSER GENERAL PUBLIC LICENSE

 * 		       Version 2.1, February 1999

 * 

 *  Copyright (C) 1991, 1999 Free Software Foundation, Inc.

 *  51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  USA

 *  Everyone is permitted to copy and distribute verbatim copies

 *  of this license document, but changing it is not allowed.

 * 

 * [This is the first released version of the Lesser GPL.  It also counts

 *  as the successor of the GNU Library Public License, version 2, hence

 *  the version number 2.1.]

 * 

 * 			    Preamble

 * 

 *   The licenses for most software are designed to take away your

 * freedom to share and change it.  By contrast, the GNU General Public

 * Licenses are intended to guarantee your freedom to share and change

 * free software--to make sure the software is free for all its users.

 * 

 *   This license, the Lesser General Public License, applies to some

 * specially designated software packages--typically libraries--of the

 * Free Software Foundation and other authors who decide to use it.  You

 * can use it too, but we suggest you first think carefully about whether

 * this license or the ordinary General Public License is the better

 * strategy to use in any particular case, based on the explanations below.

 * 

 *   When we speak of free software, we are referring to freedom of use,

 * not price.  Our General Public Licenses are designed to make sure that

 * you have the freedom to distribute copies of free software (and charge

 * for this service if you wish); that you receive source code or can get

 * it if you want it; that you can change the software and use pieces of

 * it in new free programs; and that you are informed that you can do

 * these things.

 * 

 *   To protect your rights, we need to make restrictions that forbid

 * distributors to deny you these rights or to ask you to surrender these

 * rights.  These restrictions translate to certain responsibilities for

 * you if you distribute copies of the library or if you modify it.

 * 

 *   For example, if you distribute copies of the library, whether gratis

 * or for a fee, you must give the recipients all the rights that we gave

 * you.  You must make sure that they, too, receive or can get the source

 * code.  If you link other code with the library, you must provide

 * complete object files to the recipients, so that they can relink them

 * with the library after making changes to the library and recompiling

 * it.  And you must show them these terms so they know their rights.

 * 

 *   We protect your rights with a two-step method: (1) we copyright the

 * library, and (2) we offer you this license, which gives you legal

 * permission to copy, distribute and/or modify the library.

 * 

 *   To protect each distributor, we want to make it very clear that

 * there is no warranty for the free library.  Also, if the library is

 * modified by someone else and passed on, the recipients should know

 * that what they have is not the original version, so that the original

 * author's reputation will not be affected by problems that might be

 * introduced by others.

 * 

 *   Finally, software patents pose a constant threat to the existence of

 * any free program.  We wish to make sure that a company cannot

 * effectively restrict the users of a free program by obtaining a

 * restrictive license from a patent holder.  Therefore, we insist that

 * any patent license obtained for a version of the library must be

 * consistent with the full freedom of use specified in this license.

 * 

 *   Most GNU software, including some libraries, is covered by the

 * ordinary GNU General Public License.  This license, the GNU Lesser

 * General Public License, applies to certain designated libraries, and

 * is quite different from the ordinary General Public License.  We use

 * this license for certain libraries in order to permit linking those

 * libraries into non-free programs.

 * 

 *   When a program is linked with a library, whether statically or using

 * a shared library, the combination of the two is legally speaking a

 * combined work, a derivative of the original library.  The ordinary

 * General Public License therefore permits such linking only if the

 * entire combination fits its criteria of freedom.  The Lesser General

 * Public License permits more lax criteria for linking other code with

 * the library.

 * 

 *   We call this license the "Lesser" General Public License because it

 * does Less to protect the user's freedom than the ordinary General

 * Public License.  It also provides other free software developers Less

 * of an advantage over competing non-free programs.  These disadvantages

 * are the reason we use the ordinary General Public License for many

 * libraries.  However, the Lesser license provides advantages in certain

 * special circumstances.

 * 

 *   For example, on rare occasions, there may be a special need to

 * encourage the widest possible use of a certain library, so that it becomes

 * a de-facto standard.  To achieve this, non-free programs must be

 * allowed to use the library.  A more frequent case is that a free

 * library does the same job as widely used non-free libraries.  In this

 * case, there is little to gain by limiting the free library to free

 * software only, so we use the Lesser General Public License.

 * 

 *   In other cases, permission to use a particular library in non-free

 * programs enables a greater number of people to use a large body of

 * free software.  For example, permission to use the GNU C Library in

 * non-free programs enables many more people to use the whole GNU

 * operating system, as well as its variant, the GNU/Linux operating

 * system.

 * 

 *   Although the Lesser General Public License is Less protective of the

 * users' freedom, it does ensure that the user of a program that is

 * linked with the Library has the freedom and the wherewithal to run

 * that program using a modified version of the Library.

 * 

 *   The precise terms and conditions for copying, distribution and

 * modification follow.  Pay close attention to the difference between a

 * "work based on the library" and a "work that uses the library".  The

 * former contains code derived from the library, whereas the latter must

 * be combined with the library in order to run.

 * 

 * 		  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 ofin 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 corat 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 accstribution 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, REPAI
