+=================================
 
-_Version 2.0, January 2004_  
-_&lt;<http://www.apache.org/licenses/>&gt;_
+_Version 3, 29 June 2007_  
+_Copyright © 2007 Free Software Foundation, Inc. &lt;<http://fsf.org/>&gt;_
 
-### Terms and Conditions for use, reproduction, and distribution
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
 
-#### 1. Definitions
 
-“License” shall mean the terms and conditions for use, reproduction, and
-distribution as defined by Sections 1 through 9 of this document.
+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.
 
-“Licensor” shall mean the copyright owner or entity authorized by the copyright
-owner that is granting the License.
+### 0. Additional Definitions
 
-“Legal Entity” shall mean the union of the acting entity and all other entities
-that control, are controlled by, or are under common control with that entity.
-For the purposes of this definition, “control” means **(i)** the power, direct or
-indirect, to cause the direction or management of such entity, whether by
-contract or otherwise, or **(ii)** ownership of fifty percent (50%) or more of the
-outstanding shares, or **(iii)** beneficial ownership of such entity.
+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.
 
-“You” (or “Your”) shall mean an individual or Legal Entity exercising
-permissions granted by this License.
+“The Library” refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
 
-“Source” form shall mean the preferred form for making modifications, including
-but not limited to software source code, documentation source, and configuration
-files.
+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.
 
-“Object” form shall mean any form resulting from mechanical transformation or
-translation of a Source form, including but not limited to compiled object code,
-generated documentation, and conversions to other media types.
+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”.
 
-“Work” shall mean the work of authorship, whether in Source or Object form, made
-available under the License, as indicated by a copyright notice that is included
-in or attached to the work (an example is provided in the Appendix below).
+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.
 
-“Derivative Works” shall mean any work, whether in Source or Object form, that
-is based on (or derived from) the Work and for which the editorial revisions,
-annotations, elaborations, or other modifications represent, as a whole, an
-original work of authorship. For the purposes of this License, Derivative Works
-shall not include works that remain separable from, or merely link (or bind by
-name) to the interfaces of, the Work and Derivative Works thereof.
+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.
 
-“Contribution” shall mean any work of authorship, including the original version
-of the Work and any modifications or additions to that Work or Derivative Works
-thereof, that is intentionally submitted to Licensor for inclusion in the Work
-by the copyright owner or by an individual or Legal Entity authorized to submit
-on behalf of the copyright owner. For the purposes of this definition,
-“submitted” means any form of electronic, verbal, or written communication sent
-to the Licensor or its representatives, including but not limited to
-communication on electronic mailing lists, source code control systems, and
-issue tracking systems that are managed by, or on behalf of, the Licensor for
-the purpose of discussing and improving the Work, but excluding communication
-that is conspicuously marked or otherwise designated in writing by the copyright
-owner as “Not a Contribution.”
+### 1. Exception to Section 3 of the GNU GPL
 
-“Contributor” shall mean Licensor and any individual or Legal Entity on behalf
-of whom a Contribution has been received by Licensor and subsequently
-incorporated within the Work.
+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. Grant of Copyright License
+### 2. Conveying Modified Versions
 
-Subject to the terms and conditions of this License, each Contributor hereby
-grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
-irrevocable copyright license to reproduce, prepare Derivative Works of,
-publicly display, publicly perform, sublicense, and distribute the Work and such
-Derivative Works in Source or Object form.
+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:
 
-#### 3. Grant of Patent License
+* **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
 
-Subject to the terms and conditions of this License, each Contributor hereby
-grants to You a perpetual, worldwide, non-exclusive, no-charge, royalty-free,
-irrevocable (except as stated in this section) patent license to make, have
-made, use, offer to sell, sell, import, and otherwise transfer the Work, where
-such license applies only to those patent claims licensable by such Contributor
-that are necessarily infringed by their Contribution(s) alone or by combination
-of their Contribution(s) with the Work to which such Contribution(s) was
-submitted. If You institute patent litigation against any entity (including a
-cross-claim or counterclaim in a lawsuit) alleging that the Work or a
-Contribution incorporated within the Work constitutes direct or contributory
-patent infringement, then any patent licenses granted to You under this License
-for that Work shall terminate as of the date such litigation is filed.
+* **b)** under the GNU GPL, with none of the additional permissions of
+  this License applicable to that copy.
 
-#### 4. Redistribution
+### 3. Object Code Incorporating Material from Library Header Files
 
-You may reproduce and distribute copies of the Work or Derivative Works thereof
-in any medium, with or without modifications, and in Source or Object form,
-provided that You meet the following conditions:
+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)** You must give any other recipients of the Work or Derivative Works a copy of
-this License; and
-* **(b)** You must cause any modified files to carry prominent notices stating that You
-changed the files; and
-* **(c)** You must retain, in the Source form of any Derivative Works that You distribute,
-all copyright, patent, trademark, and attribution notices from the Source form
-of the Work, excluding those notices that do not pertain to any part of the
-Derivative Works; and
-* **(d)** If the Work includes a “NOTICE” text file as part of its distribution, then any
-Derivative Works that You distribute must include a readable copy of the
-attribution notices contained within such NOTICE file, excluding those notices
-that do not pertain to any part of the Derivative Works, in at least one of the
-following places: within a NOTICE text file distributed as part of the
-Derivative Works; within the Source form or documentation, if provided along
-with the Derivative Works; or, within a display generated by the Derivative
-Works, if and wherever such third-party notices normally appear. The contents of
-the NOTICE file are for informational purposes only and do not modify the
-License. You may add Your own attribution notices within Derivative Works that
-You distribute, alongside or as an addendum to the NOTICE text from the Work,
-provided that such additional attribution notices cannot be construed as
-modifying the License.
+* **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.
 
-You may add Your own copyright statement to Your modifications and may provide
-additional or different license terms and conditions for use, reproduction, or
-distribution of Your modifications, or for any such Derivative Works as a whole,
-provided Your use, reproduction, and distribution of the Work otherwise complies
-with the conditions stated in this License.
+### 4. Combined Works
 
-#### 5. Submission of Contributions
+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:
 
-Unless You explicitly state otherwise, any Contribution intentionally submitted
-for inclusion in the Work by You to the Licensor shall be under the terms and
-conditions of this License, without any additional terms or conditions.
-Notwithstanding the above, nothing herein shall supersede or modify the terms of
-any separate license agreement you may have executed with Licensor regarding
-such Contributions.
+* **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.
 
-#### 6. Trademarks
+* **b)** Accompany the Combined Work with a copy of the GNU GPL and this license
+  document.
 
-This License does not grant permission to use the trade names, trademarks,
-service marks, or product names of the Licensor, except as required for
-reasonable and customary use in describing the origin of the Work and
-reproducing the content of the NOTICE file.
+* **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.
 
-#### 7. Disclaimer of Warranty
+* **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.
 
-Unless required by applicable law or agreed to in writing, Licensor provides the
-Work (and each Contributor provides its Contributions) on an “AS IS” BASIS,
-WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied,
-including, without limitation, any warranties or conditions of TITLE,
-NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A PARTICULAR PURPOSE. You are
-solely responsible for determining the appropriateness of using or
-redistributing the Work and assume any risks associated with Your exercise of
-permissions under this License.
+* **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.)
 
-#### 8. Limitation of Liability
+### 5. Combined Libraries
 
-In no event and under no legal theory, whether in tort (including negligence),
-contract, or otherwise, unless required by applicable law (such as deliberate
-and grossly negligent acts) or agreed to in writing, shall any Contributor be
-liable to You for damages, including any direct, indirect, special, incidental,
-or consequential damages of any character arising as a result of this License or
-out of the use or inability to use the Work (including but not limited to
-damages for loss of goodwill, work stoppage, computer failure or malfunction, or
-any and all other commercial damages or losses), even if such Contributor has
-been advised of the possibility of such damages.
+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:
 
-#### 9. Accepting Warranty or Additional Liability
+* **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.
 
-While redistributing the Work or Derivative Works thereof, You may choose to
-offer, and charge a fee for, acceptance of support, warranty, indemnity, or
-other liability obligations and/or rights consistent with this License. However,
-in accepting such obligations, You may act only on Your own behalf and on Your
-sole responsibility, not on behalf of any other Contributor, and only if You
-agree to indemnify, defend, and hold each Contributor harmless for any liability
-incurred by, or claims asserted against, such Contributor by reason of your
-accepting any such warranty or additional liability.
+### 6. Revised Versions of the GNU Lesser General Public License
 
-_END OF TERMS AND CONDITIONS_
+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.
