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