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

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