christian@0: GNU LESSER GENERAL PUBLIC LICENSE christian@0: Version 3, 29 June 2007 christian@0: christian@0: Copyright (C) 2007 Free Software Foundation, Inc. christian@0: Everyone is permitted to copy and distribute verbatim copies christian@0: of this license document, but changing it is not allowed. christian@0: christian@0: christian@0: This version of the GNU Lesser General Public License incorporates christian@0: the terms and conditions of version 3 of the GNU General Public christian@0: License, supplemented by the additional permissions listed below. christian@0: christian@0: 0. Additional Definitions. christian@0: christian@0: As used herein, "this License" refers to version 3 of the GNU Lesser christian@0: General Public License, and the "GNU GPL" refers to version 3 of the GNU christian@0: General Public License. christian@0: christian@0: "The Library" refers to a covered work governed by this License, christian@0: other than an Application or a Combined Work as defined below. christian@0: christian@0: An "Application" is any work that makes use of an interface provided christian@0: by the Library, but which is not otherwise based on the Library. christian@0: Defining a subclass of a class defined by the Library is deemed a mode christian@0: of using an interface provided by the Library. christian@0: christian@0: A "Combined Work" is a work produced by combining or linking an christian@0: Application with the Library. The particular version of the Library christian@0: with which the Combined Work was made is also called the "Linked christian@0: Version". christian@0: christian@0: The "Minimal Corresponding Source" for a Combined Work means the christian@0: Corresponding Source for the Combined Work, excluding any source code christian@0: for portions of the Combined Work that, considered in isolation, are christian@0: based on the Application, and not on the Linked Version. christian@0: christian@0: The "Corresponding Application Code" for a Combined Work means the christian@0: object code and/or source code for the Application, including any data christian@0: and utility programs needed for reproducing the Combined Work from the christian@0: Application, but excluding the System Libraries of the Combined Work. christian@0: christian@0: 1. Exception to Section 3 of the GNU GPL. christian@0: christian@0: You may convey a covered work under sections 3 and 4 of this License christian@0: without being bound by section 3 of the GNU GPL. christian@0: christian@0: 2. Conveying Modified Versions. christian@0: christian@0: If you modify a copy of the Library, and, in your modifications, a christian@0: facility refers to a function or data to be supplied by an Application christian@0: that uses the facility (other than as an argument passed when the christian@0: facility is invoked), then you may convey a copy of the modified christian@0: version: christian@0: christian@0: a) under this License, provided that you make a good faith effort to christian@0: ensure that, in the event an Application does not supply the christian@0: function or data, the facility still operates, and performs christian@0: whatever part of its purpose remains meaningful, or christian@0: christian@0: b) under the GNU GPL, with none of the additional permissions of christian@0: this License applicable to that copy. christian@0: christian@0: 3. Object Code Incorporating Material from Library Header Files. christian@0: christian@0: The object code form of an Application may incorporate material from christian@0: a header file that is part of the Library. You may convey such object christian@0: code under terms of your choice, provided that, if the incorporated christian@0: material is not limited to numerical parameters, data structure christian@0: layouts and accessors, or small macros, inline functions and templates christian@0: (ten or fewer lines in length), you do both of the following: christian@0: christian@0: a) Give prominent notice with each copy of the object code that the christian@0: Library is used in it and that the Library and its use are christian@0: covered by this License. christian@0: christian@0: b) Accompany the object code with a copy of the GNU GPL and this license christian@0: document. christian@0: christian@0: 4. Combined Works. christian@0: christian@0: You may convey a Combined Work under terms of your choice that, christian@0: taken together, effectively do not restrict modification of the christian@0: portions of the Library contained in the Combined Work and reverse christian@0: engineering for debugging such modifications, if you also do each of christian@0: the following: christian@0: christian@0: a) Give prominent notice with each copy of the Combined Work that christian@0: the Library is used in it and that the Library and its use are christian@0: covered by this License. christian@0: christian@0: b) Accompany the Combined Work with a copy of the GNU GPL and this license christian@0: document. christian@0: christian@0: c) For a Combined Work that displays copyright notices during christian@0: execution, include the copyright notice for the Library among christian@0: these notices, as well as a reference directing the user to the christian@0: copies of the GNU GPL and this license document. christian@0: christian@0: d) Do one of the following: christian@0: christian@0: 0) Convey the Minimal Corresponding Source under the terms of this christian@0: License, and the Corresponding Application Code in a form christian@0: suitable for, and under terms that permit, the user to christian@0: recombine or relink the Application with a modified version of christian@0: the Linked Version to produce a modified Combined Work, in the christian@0: manner specified by section 6 of the GNU GPL for conveying christian@0: Corresponding Source. christian@0: christian@0: 1) Use a suitable shared library mechanism for linking with the christian@0: Library. A suitable mechanism is one that (a) uses at run time christian@0: a copy of the Library already present on the user's computer christian@0: system, and (b) will operate properly with a modified version christian@0: of the Library that is interface-compatible with the Linked christian@0: Version. christian@0: christian@0: e) Provide Installation Information, but only if you would otherwise christian@0: be required to provide such information under section 6 of the christian@0: GNU GPL, and only to the extent that such information is christian@0: necessary to install and execute a modified version of the christian@0: Combined Work produced by recombining or relinking the christian@0: Application with a modified version of the Linked Version. (If christian@0: you use option 4d0, the Installation Information must accompany christian@0: the Minimal Corresponding Source and Corresponding Application christian@0: Code. If you use option 4d1, you must provide the Installation christian@0: Information in the manner specified by section 6 of the GNU GPL christian@0: for conveying Corresponding Source.) christian@0: christian@0: 5. Combined Libraries. christian@0: christian@0: You may place library facilities that are a work based on the christian@0: Library side by side in a single library together with other library christian@0: facilities that are not Applications and are not covered by this christian@0: License, and convey such a combined library under terms of your christian@0: choice, if you do both of the following: christian@0: christian@0: a) Accompany the combined library with a copy of the same work based christian@0: on the Library, uncombined with any other library facilities, christian@0: conveyed under the terms of this License. christian@0: christian@0: b) Give prominent notice with the combined library that part of it christian@0: is a work based on the Library, and explaining where to find the christian@0: accompanying uncombined form of the same work. christian@0: christian@0: 6. Revised Versions of the GNU Lesser General Public License. christian@0: christian@0: The Free Software Foundation may publish revised and/or new versions christian@0: of the GNU Lesser General Public License from time to time. Such new christian@0: versions will be similar in spirit to the present version, but may christian@0: differ in detail to address new problems or concerns. christian@0: christian@0: Each version is given a distinguishing version number. If the christian@0: Library as you received it specifies that a certain numbered version christian@0: of the GNU Lesser General Public License "or any later version" christian@0: applies to it, you have the option of following the terms and christian@0: conditions either of that published version or of any later version christian@0: published by the Free Software Foundation. If the Library as you christian@0: received it does not specify a version number of the GNU Lesser christian@0: General Public License, you may choose any version of the GNU Lesser christian@0: General Public License ever published by the Free Software Foundation. christian@0: christian@0: If the Library as you received it specifies that a proxy can decide christian@0: whether future versions of the GNU Lesser General Public License shall christian@0: apply, that proxy's public statement of acceptance of any version is christian@0: permanent authorization for you to choose that version for the christian@0: Library.
