149c5db199SXin Li
159c5db199SXin Li  As used herein, "this License" refers to version 3 of the GNU Lesser

179c5db199SXin LiGeneral Public License.
189c5db199SXin Li
199c5db199SXin Li  "The Library" refers to a covered work governed by this License,
209c5db199SXin Liother than an Application or a Combined Work as defined below.
219c5db199SXin Li
229c5db199SXin Li  An "Application" is any work that makes use of an interface provided
239c5db199SXin Liby the Library, but which is not otherwise based on the Library.
249c5db199SXin LiDefining a subclass of a class defined by the Library is deemed a mode
259c5db199SXin Liof using an interface provided by the Library.
269c5db199SXin Li
279c5db199SXin Li  A "Combined Work" is a work produced by combining or linking an
289c5db199SXin LiApplication with the Library.  The particular version of the Library
299c5db199SXin Liwith which the Combined Work was made is also called the "Linked
309c5db199SXin LiVersion".
319c5db199SXin Li
329c5db199SXin Li  The "Minimal Corresponding Source" for a Combined Work means the
339c5db199SXin LiCorresponding Source for the Combined Work, excluding any source code
349c5db199SXin Lifor portions of the Combined Work that, considered in isolation, are
359c5db199SXin Libased on the Application, and not on the Linked Version.
369c5db199SXin Li
379c5db199SXin Li  The "Corresponding Application Code" for a Combined Work means the
389c5db199SXin Liobject code and/or source code for the Application, including any data
399c5db199SXin Liand utility programs needed for reproducing the Combined Work from the
409c5db199SXin LiApplication, but excluding the System Libraries of the Combined Work.
419c5db199SXin Li
429c5db199SXin Li  1. Exception to Section 3 of the GNU GPL.
439c5db199SXin Li
449c5db199SXin Li  You may convey a covered work under sections 3 and 4 of this License
459c5db199SXin Liwithout being bound by section 3 of the GNU GPL.
469c5db199SXin Li
479c5db199SXin Li  2. Conveying Modified Versions.
489c5db199SXin Li
499c5db199SXin Li  If you modify a copy of the Library, and, in your modifications, a
509c5db199SXin Lifacility refers to a function or data to be supplied by an Application
519c5db199SXin Lithat uses the facility (other than as an argument passed when the
529c5db199SXin Lifacility is invoked), then you may convey a copy of the modified
539c5db199SXin Liversion:
549c5db199SXin Li
559c5db199SXin Li   a) under this License, provided that you make a good faith effort to
569c5db199SXin Li   ensure that, in the event an Application does not supply the
579c5db199SXin Li   function or data, the facility still operates, and performs
589c5db199SXin Li   whatever part of its purpose remains meaningful, or
599c5db199SXin Li
609c5db199SXin Li   b) under the GNU GPL, with none of the additional permissions of
619c5db199SXin Li   this License applicable to that copy.

639c5db199SXin Li  3. Object Code Incorporating Material from Library Header Files.
649c5db199SXin Li
659c5db199SXin Li  The object code form of an Application may incorporate material from
669c5db199SXin Lia header file that is part of the Library.  You may convey such object
679c5db199SXin Licode under terms of your choice, provided that, if the incorporated
689c5db199SXin Limaterial is not limited to numerical parameters, data structure
699c5db199SXin Lilayouts and accessors, or small macros, inline functions and templates
709c5db199SXin Li(ten or fewer lines in length), you do both of the following:
719c5db199SXin Li
729c5db199SXin Li   a) Give prominent notice with each copy of the object code that the
739c5db199SXin Li   Library is used in it and that the Library and its use are
749c5db199SXin Li   covered by this License.
759c5db199SXin Li
769c5db199SXin Li   b) Accompany the object code with a copy of the GNU GPL and this license
779c5db199SXin Li   document.
789c5db199SXin Li
799c5db199SXin Li  4. Combined Works.
809c5db199SXin Li
819c5db199SXin Li  You may convey a Combined Work under terms of your choice that,
829c5db199SXin Litaken together, effectively do not restrict modification of the
839c5db199SXin Liportions of the Library contained in the Combined Work and reverse
849c5db199SXin Liengineering for debugging such modifications, if you also do each of
859c5db199SXin Lithe following:
869c5db199SXin Li
879c5db199SXin Li   a) Give prominent notice with each copy of the Combined Work that
889c5db199SXin Li   the Library is used in it and that the Library and its use are
899c5db199SXin Li   covered by this License.
909c5db199SXin Li
919c5db199SXin Li   b) Accompany the Combined Work with a copy of the GNU GPL and this license

1029c5db199SXin Li       License, and the Corresponding Application Code in a form
1039c5db199SXin Li       suitable for, and under terms that permit, the user to
1049c5db199SXin Li       recombine or relink the Application with a modified version of
1059c5db199SXin Li       the Linked Version to produce a modified Combined Work, in the
1069c5db199SXin Li       manner specified by section 6 of the GNU GPL for conveying
1079c5db199SXin Li       Corresponding Source.
1089c5db199SXin Li
1099c5db199SXin Li       1) Use a suitable shared library mechanism for linking with the
1109c5db199SXin Li       Library.  A suitable mechanism is one that (a) uses at run time
1119c5db199SXin Li       a copy of the Library already present on the user's computer
1129c5db199SXin Li       system, and (b) will operate properly with a modified version
1139c5db199SXin Li       of the Library that is interface-compatible with the Linked
1149c5db199SXin Li       Version.
1159c5db199SXin Li
1169c5db199SXin Li   e) Provide Installation Information, but only if you would otherwise
1179c5db199SXin Li   be required to provide such information under section 6 of the

1199c5db199SXin Li   necessary to install and execute a modified version of the
1209c5db199SXin Li   Combined Work produced by recombining or relinking the
1219c5db199SXin Li   Application with a modified version of the Linked Version. (If
1229c5db199SXin Li   you use option 4d0, the Installation Information must accompany
1239c5db199SXin Li   the Minimal Corresponding Source and Corresponding Application
1249c5db199SXin Li   Code. If you use option 4d1, you must provide the Installation
1259c5db199SXin Li   Information in the manner specified by section 6 of the GNU GPL
1269c5db199SXin Li   for conveying Corresponding Source.)

1299c5db199SXin Li
1309c5db199SXin Li  You may place library facilities that are a work based on the
1319c5db199SXin LiLibrary side by side in a single library together with other library
1329c5db199SXin Lifacilities that are not Applications and are not covered by this
1339c5db199SXin LiLicense, and convey such a combined library under terms of your

1369c5db199SXin Li   a) Accompany the combined library with a copy of the same work based
1379c5db199SXin Li   on the Library, uncombined with any other library facilities,
1389c5db199SXin Li   conveyed under the terms of this License.
1399c5db199SXin Li
1409c5db199SXin Li   b) Give prominent notice with the combined library that part of it
1419c5db199SXin Li   is a work based on the Library, and explaining where to find the
1429c5db199SXin Li   accompanying uncombined form of the same work.
1439c5db199SXin Li
1449c5db199SXin Li  6. Revised Versions of the GNU Lesser General Public License.
1459c5db199SXin Li
1469c5db199SXin Li  The Free Software Foundation may publish revised and/or new versions
1479c5db199SXin Liof the GNU Lesser General Public License from time to time. Such new

1499c5db199SXin Lidiffer in detail to address new problems or concerns.
1509c5db199SXin Li
1519c5db199SXin Li  Each version is given a distinguishing version number. If the
1529c5db199SXin LiLibrary as you received it specifies that a certain numbered version
1539c5db199SXin Liof the GNU Lesser General Public License "or any later version"
1549c5db199SXin Liapplies to it, you have the option of following the terms and
1559c5db199SXin Liconditions either of that published version or of any later version
1569c5db199SXin Lipublished by the Free Software Foundation. If the Library as you
1579c5db199SXin Lireceived it does not specify a version number of the GNU Lesser
1589c5db199SXin LiGeneral Public License, you may choose any version of the GNU Lesser
1599c5db199SXin LiGeneral Public License ever published by the Free Software Foundation.
1609c5db199SXin Li
1619c5db199SXin Li  If the Library as you received it specifies that a proxy can decide
1629c5db199SXin Liwhether future versions of the GNU Lesser General Public License shall
1639c5db199SXin Liapply, that proxy's public statement of acceptance of any version is
1649c5db199SXin Lipermanent authorization for you to choose that version for the
1659c5db199SXin LiLibrary.
