GNU LIBRARY GENERAL PUBLIC LICENSE**********************************                         Version 2, June 1991     Copyright (C) 1991 Free Software Foundation, Inc.     59 Temple Place -- Suite 330, Boston, MA 02111-1307, 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 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 yourfreedom to share and change it.  By contrast, the GNU General PublicLicenses are intended to guarantee your freedom to share and changefree software--to make sure the software is free for all its users.   This license, the Library General Public License, applies to somespecially designated Free Software Foundation software, and to anyother libraries whose authors decide to use it.  You can use it foryour libraries, too.   When we speak of free software, we are referring to freedom, notprice.  Our General Public Licenses are designed to make sure that youhave the freedom to distribute copies of free software (and charge forthis service if you wish), that you receive source code or can get itif you want it, that you can change the software or use pieces of it innew free programs; and that you know you can do these things.   To protect your rights, we need to make restrictions that forbidanyone to deny you these rights or to ask you to surrender the rights.These restrictions translate to certain responsibilities for you if youdistribute copies of the library, or if you modify it.   For example, if you distribute copies of the library, whether gratisor for a fee, you must give the recipients all the rights that we gaveyou.  You must make sure that they, too, receive or can get the sourcecode.  If you link a program with the library, you must providecomplete object files to the recipients so that they can relink themwith the library, after making changes to the library and recompilingit.  And you must show them these terms so they know their rights.   Our method of protecting your rights has two steps: (1) copyrightthe library, and (2) offer you this license which gives you legalpermission to copy, distribute and/or modify the library.   Also, for each distributor's protection, we want to make certainthat everyone understands that there is no warranty for this freelibrary.  If the library is modified by someone else and passed on, wewant its recipients to know that what they have is not the originalversion, so that any problems introduced by others will not reflect onthe original authors' reputations.   Finally, any free program is threatened constantly by softwarepatents.  We wish to avoid the danger that companies distributing freesoftware will individually obtain patent licenses, thus in effecttransforming the program into proprietary software.  To prevent this,we have made it clear that any patent must be licensed for everyone'sfree use or not licensed at all.   Most GNU software, including some libraries, is covered by theordinary GNU General Public License, which was designed for utilityprograms.  This license, the GNU Library General Public License,applies to certain designated libraries.  This license is quitedifferent from the ordinary one; be sure to read it in full, and don'tassume that anything in it is the same as in the ordinary license.   The reason we have a separate public license for some libraries isthat they blur the distinction we usually make between modifying oradding to a program and simply using it.  Linking a program with alibrary, without changing the library, is in some sense simply usingthe library, and is analogous to running a utility program orapplication program.  However, in a textual and legal sense, the linkedexecutable 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 GeneralPublic License for libraries did not effectively promote softwaresharing, because most developers did not use the libraries.  Weconcluded that weaker conditions might promote sharing better.   However, unrestricted linking of non-free programs would deprive theusers of those programs of all benefit from the free status of thelibraries themselves.  This Library General Public License is intendedto permit developers of non-free programs to use free libraries, whilepreserving your freedom as a user of such programs to change the freelibraries that are incorporated in them.  (We have not seen how toachieve this as regards changes in header files, but we have achievedit as regards changes in the actual functions of the Library.)  Thehope is that this will lead to faster development of free libraries.   The precise terms and conditions for copying, distribution andmodification follow.  Pay close attention to the difference between a"work based on the library" and a "work that uses the library".  Theformer contains code derived from the library, while the latter onlyworks together with the library.   Note that it is possible for a library to be covered by the ordinaryGeneral 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
