GNU LESSER GENERAL PUBLIC LICENSEVersion 3, 29 June 2007Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>Everyone is permitted to copy and distribute verbatim copiesof this license document, but changing it is not allowed.This version of the GNU Lesser General Public License incorporatesthe terms and conditions of version 3 of the GNU General PublicLicense, supplemented by the additional permissions listed below.0. Additional Definitions.As used herein, "this License" refers to version 3 of the GNU LesserGeneral Public License, and the "GNU GPL" refers to version 3 of the GNUGeneral Public License."The Library" refers to a covered work governed by this License,other than an Application or a Combined Work as defined below.An "Application" is any work that makes use of an interface providedby the Library, but which is not otherwise based on the Library.Defining a subclass of a class defined by the Library is deemed a modeof using an interface provided by the Library.A "Combined Work" is a work produced by combining or linking anApplication with the Library. The particular version of the Librarywith which the Combined Work was made is also called the "LinkedVersion".The "Minimal Corresponding Source" for a Combined Work means theCorresponding Source for the Combined Work, excluding any source codefor portions of the Combined Work that, considered in isolation, arebased on the Application, and not on the Linked Version.The "Corresponding Application Code" for a Combined Work means theobject code and/or source code for the Application, including any dataand utility programs needed for reproducing the Combined Work from theApplication, but excluding the System Libraries of the Combined Work.1. Exception to Section 3 of the GNU GPL.You may convey a covered work under sections 3 and 4 of this Licensewithout being bound by section 3 of the GNU GPL.2. Conveying Modified Versions.If you modify a copy of the Library, and, in your modifications, afacility refers to a function or data to be supplied by an Applicationthat uses the facility (other than as an argument passed when thefacility is invoked), then you may convey a copy of the modifiedversion:a) under this License, provided that you make a good faith effort toensure that, in the event an Application does not supply thefunction or data, the facility still operates, and performswhatever part of its purpose remains meaningful, orb) under the GNU GPL, with none of the additional permissions ofthis License applicable to that copy.3. Object Code Incorporating Material from Library Header Files.The object code form of an Application may incorporate material froma header file that is part of the Library. You may convey such objectcode under terms of your choice, provided that, if the incorporatedmaterial is not limited to numerical parameters, data structurelayouts and accessors, or small macros, inline functions and templates(ten or fewer lines in length), you do both of the following:a) Give prominent notice with each copy of the object code that theLibrary is used in it and that the Library and its use arecovered by this License.b) Accompany the object code with a copy of the GNU GPL and this licensedocument.4. Combined Works.You may convey a Combined Work under terms of your choice that,taken together, effectively do not restrict modification of theportions of the Library contained in the Combined Work and reverseengineering for debugging such modifications, if you also do each ofthe following:a) Give prominent notice with each copy of the Combined Work thatthe Library is used in it and that the Library and its use arecovered by this License.b) Accompany the Combined Work with a copy of the GNU GPL and this licensedocument.c) For a Combined Work that displays copyright notices duringexecution, include the copyright notice for the Library amongthese notices, as well as a reference directing the user to thecopies of the GNU GPL and this license document.d) Do one of the following:0) Convey the Minimal Corresponding Source under the terms of thisLicense, and the Corresponding Application Code in a formsuitable for, and under terms that permit, the user torecombine or relink the Application with a modified version ofthe Linked Version to produce a modified Combined Work, in themanner specified by section 6 of the GNU GPL for conveyingCorresponding Source.1) Use a suitable shared library mechanism for linking with theLibrary. A suitable mechanism is one that (a) uses at run timea copy of the Library already present on the user's computersystem, and (b) will operate properly with a modified versionof the Library that is interface-compatible with the LinkedVersion.e) Provide Installation Information, but only if you would otherwisebe required to provide such information under section 6 of theGNU GPL, and only to the extent that such information isnecessary to install and execute a modified version of theCombined Work produced by recombining or relinking theApplication with a modified version of the Linked Version. (Ifyou use option 4d0, the Installation Information must accompanythe Minimal Corresponding Source and Corresponding ApplicationCode. If you use option 4d1, you must provide the InstallationInformation in the manner specified by section 6 of the GNU GPLfor conveying Corresponding Source.)5. Combined Libraries.You may place library facilities that are a work based on theLibrary side by side in a single library together with other libraryfacilities that are not Applications and are not covered by thisLicense, and convey such a combined library under terms of yourchoice, if you do both of the following:a) Accompany the combined library with a copy of the same work basedon the Library, uncombined with any other library facilities,conveyed under the terms of this License.b) Give prominent notice with the combined library that part of itis a work based on the Library, and explaining where to find theaccompanying uncombined form of the same work.6. Revised Versions of the GNU Lesser General Public License.The Free Software Foundation may publish revised and/or new versionsof the GNU Lesser General Public License from time to time. Such newversions will be similar in spirit to the present version, but maydiffer in detail to address new problems or concerns.Each version is given a distinguishing version number. If theLibrary as you received it specifies that a certain numbered versionof the GNU Lesser General Public License "or any later version"applies to it, you have the option of following the terms andconditions either of that published version or of any later versionpublished by the Free Software Foundation. If the Library as youreceived it does not specify a version number of the GNU LesserGeneral Public License, you may choose any version of the GNU LesserGeneral Public License ever published by the Free Software Foundation.If the Library as you received it specifies that a proxy can decidewhether future versions of the GNU Lesser General Public License shallapply, that proxy's public statement of acceptance of any version ispermanent authorization for you to choose that version for theLibrary.
