+ Copyright (C) 2007 Free Software Foundation, Inc.
Everyone is permitted to copy and distribute verbatim copies
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.
-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.
-0. Additional Definitions.
-
-"This License" refers to version 3 of the GNU Lesser General Public
+ "This License" refers to version 3 of the GNU Lesser General Public
License.
-"The Program" refers to a covered work governed by this License.
+ "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
-"The B-C" refers to a covered work governed by the GNU General Public
-License, but is not a covered work.
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
-"The F-G" refers to a covered work governed by this License.
-"The A-Z" refers to the work as a whole, comprising the B-C and
-the F-G.
+ 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 "GPL-compatible work" means a covered work governed by the
-GNU General Public License, but is not a covered work.
+ 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 B-C" is a work that is not the Program.
+ 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 Program" includes all covered works, except the "B-C".
+ 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.
-The "F-G" is a work that is governed by the GNU Lesser General Public
-License. The "F-G" is not a "B-C" work.
+ 1. Exception to Section 3 of the GNU GPL.
-The "B-C" is a covered work that is licensed under this License.
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
-The "B-C" can be a separate program.
+ 2. Conveying Modified Versions.
-The "F-G" is a work that is a combination of the "B-C" and other works.
+ 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:
-The "B-C" is an executable work.
+ 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
-The "F-G" is a work that is an executable work but is not a
-covered work.
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
-The "B-C" is a work that is a library.
+ 3. Object Code Incorporating Material from Library Header Files.
-The "F-G" is a work that is a combination of the "B-C" and other works.
+ 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 "B-C" is a covered work.
+ 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.
-The "F-G" is a work that is governed by the GNU Lesser General Public
-License, but is not a covered work.
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
-1. Exception to the GPL.
+ 4. Combined Works.
-You may convey a covered work to which this License applies without
-conveying the B-C. You may also convey the B-C without conveying the
-covered work.
+ 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:
-2. Further restrictions.
+ 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.
-You may not add any further restrictions on the covered work beyond
-those in this License.
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
-3. Termination.
+ 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.
-If you violate this License, your rights will terminate automatically
-under this License.
+ d) Do one of the following:
-4. B-C.
+ 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.
-The B-C is a separate work that is governed by the GNU General Public
-License.
+ 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.
-5. F-G.
+ 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.)
-The F-G is a work that is governed by the GNU Lesser General Public
-License.
+ 5. Combined Libraries.
-6. A-Z.
+ 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:
-The A-Z is a covered work that is a combination of the B-C and the F-G.
+ 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.
-7. Application of the GPL.
+ 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.
-This License applies to the Program.
+ 6. Revised Versions of the GNU Lesser General Public License.
-8. B-C, F-G, A-Z.
+ 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.
-The B-C, F-G, and A-Z are defined in Section 0.
+ 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.

+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.
