                2. License Grants and Conditions 2.1. Grants Each Contributor hereby grants You a world-wide, royalty-free, non-exclusive license:

                under intellectual property rights (other than patent or trademark) Licensable by such Contributor to use, reproduce, make available, modify, display, perform, distribute, and otherwise exploit its Contributions, either on an unmodified basis, with Modifications, or as part of a Larger Work; and

                under Patent Claims of such Contributor to make, use, sell, offer for sale, have made, import, and otherwise transfer either its Contributions or its Contributor Version.

                2.2. Effective Date The licenses granted in Section 2.1 with respect to any Contribution become effective for each Contribution on the date the Contributor first distributes such Contribution.

                2.3. Limitations on Grant Scope The licenses granted in this Section 2 are the only rights granted under this License. No additional rights or licenses will be implied from the distribution or licensing of Covered Software under this License. Notwithstanding Section 2.1(b) above, no patent license is granted by a Contributor:

                for any code that a Contributor has removed from Covered Software; or

                for infringements caused by: (i) Your and any other third party’s modifications of Covered Software, or (ii) the combination of its Contributions with other software (except as part of its Contributor Version); or

                under Patent Claims infringed by Covered Software in the absence of its Contributions.

                This License does not grant any rights in the trademarks, service marks, or logos of any Contributor (except as may be necessary to comply with the notice requirements in Section 3.4).

                2.4. Subsequent Licenses No Contributor makes additional grants as a result of Your choice to distribute the Covered Software under a subsequent version of this License (see Section 10.2) or under the terms of a Secondary License (if permitted under the terms of Section 3.3).

                2.5. Representation Each Contributor represents that the Contributor believes its Contributions are its original creation(s) or it has sufficient rights to grant the rights to its Contributions conveyed by this License.

                2.6. Fair Use This License is not intended to limit any rights You have under applicable copyright doctrines of fair use, fair dealing, or other equivalents.

                2.7. Conditions Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in Section 2.1.

                3. Responsibilities 3.1. Distribution of Source Form All distribution of Covered Software in Source Code Form, including any Modifications that You create or to which You contribute, must be under the terms of this License. You must inform recipients that the Source Code Form of the Covered Software is governed by the terms of this License, and how they can obtain a copy of this License. You may not attempt to alter or restrict the recipients’ rights in the Source Code Form.

                3.2. Distribution of Executable Form If You distribute Covered Software in Executable Form then:

                such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and

                You may distribute such Executable Form under the terms of this License, or sublicense it under different terms, provided that the license for the Executable Form does not attempt to limit or alter the recipients’ rights in the Source Code Form under this License.

                3.3. Distribution of a Larger Work You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s).

                3.4. Notices You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy known factual inaccuracies.

                3.5. Application of Additional Terms You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction.

                4. Inability to Comply Due to Statute or Regulation If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Software due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be placed in a text file included with all distributions of the Covered Software under this License. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it.

                5. Termination 5.1. The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated (a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30 days after Your receipt of the notice.

                5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate.

                5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or Your distributors under this License prior to termination shall survive termination.

                6. Disclaimer of Warranty Covered Software is provided under this License on an “as is” basis, without warranty of any kind, either expressed, implied, or statutory, including, without limitation, warranties that the Covered Software is free of defects, merchantable, fit for a particular purpose or non-infringing. The entire risk as to the quality and performance of the Covered Software is with You. Should any Covered Software prove defective in any respect, You (not any Contributor) assume the cost of any necessary servicing, repair, or correction. This disclaimer of warranty constitutes an essential part of this License. No use of any Covered Software is authorized under this License except under this disclaimer.

                7. Limitation of Liability Under no circumstances and under no legal theory, whether tort (including negligence), contract, or otherwise, shall any Contributor, or anyone who distributes Covered Software as permitted above, be liable to You for any direct, indirect, special, incidental, or consequential damages of any character including, without limitation, damages for lost profits, loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses, even if such party shall have been informed of the possibility of such damages. This limitation of liability shall not apply to liability for death or personal injury resulting from such party’s negligence to the extent applicable law prohibits such limitation. Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so this exclusion and limitation may not apply to You.

                8. Litigation Any litigation relating to this License may be brought only in the courts of a jurisdiction where the defendant maintains its principal place of business and such litigation shall be governed by laws of that jurisdiction, without reference to its conflict-of-law provisions. Nothing in this Section shall prevent a party’s ability to bring cross-claims or counter-claims.

                9. Miscellaneous This License represents the complete agreement concerning the subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable. Any law or regulation which provides that the language of a contract shall be construed against the drafter shall not be used to construe this License against a Contributor.

                10. Versions of the License 10.1. New Versions Mozilla Foundation is the license steward. Except as provided in Section 10.3, no one other than the license steward has the right to modify or publish new versions of this License. Each version will be given a distinguishing version number.

                10.2. Effect of New Versions You may distribute the Covered Software under the terms of the version of the License under which You originally received the Covered Software, or under the terms of any subsequent version published by the license steward.

                10.3. Modified Versions If you create software not governed by this License, and you want to create a new license for such software, you may create and use a modified version of this License if you rename the license and remove any references to the name of the license steward (except to note that such modified license differs from this License).

                10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses If You choose to distribute Source Code Form that is Incompatible With Secondary Licenses under the terms of this version of the License, the notice described in Exhibit B of this License must be attached.

                Exhibit A - Source Code Form License Notice This Source Code Form is subject to the terms of the Mozilla Public License, v. 2.0. If a copy of the MPL was not distributed with this file, You can obtain one at http://mozilla.org/MPL/2.0/.

                If it is not possible or desirable to put the notice in a particular file, then You may include the notice in a location (such as a LICENSE file in a relevant directory) where a recipient would be likely to look for such a notice.

                You may add additional accurate notices of copyright ownership.

                Exhibit B - “Incompatible With Secondary Licenses” Notice This Source Code Form is “Incompatible With Secondary Licenses”, as defined by the Mozilla Public License, v. 2.0.

                      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.

                   4. Redistribution. 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:

                      (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.

                      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.

                   5. Submission of Contributions. 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.

                   6. Trademarks. 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.

                   7. Disclaimer of Warranty. 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.

                   8. Limitation of Liability. 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.

                   9. Accepting Warranty or Additional Liability. 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.

                   END OF TERMS AND CONDITIONS

                GNU LESSER GENERAL PUBLIC LICENSE
                Version 3, 29 June 2007

                Copyright © 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.

                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.

                2. License Grants and Conditions
                --------------------------------

                2.1. Grants

                Each Contributor hereby grants You a world-wide, royalty-free,
                non-exclusive license:

                (a) under intellectual property rights (other than patent or trademark)
                    Licensable by such Contributor to use, reproduce, make available,
                    modify, display, perform, distribute, and otherwise exploit its
                    Contributions, either on an unmodified basis, with Modifications, or
                    as part of a Larger Work; and

                (b) under Patent Claims of such Contributor to make, use, sell, offer
                    for sale, have made, import, and otherwise transfer either its
                    Contributions or its Contributor Version.

                2.2. Effective Date

                The licenses granted in Section 2.1 with respect to any Contribution
                become effective for each Contribution on the date the Contributor first
                distributes such Contribution.

                2.3. Limitations on Grant Scope

                The licenses granted in this Section 2 are the only rights granted under
                this License. No additional rights or licenses will be implied from the
                distribution or licensing of Covered Software under this License.
                Notwithstanding Section 2.1(b) above, no patent license is granted by a
                Contributor:

                (a) for any code that a Contributor has removed from Covered Software;
                    or

                (b) for infringements caused by: (i) Your and any other third party's
                    modifications of Covered Software, or (ii) the combination of its
                    Contributions with other software (except as part of its Contributor
                    Version); or

                (c) under Patent Claims infringed by Covered Software in the absence of
                    its Contributions.

                This License does not grant any rights in the trademarks, service marks,
                or logos of any Contributor (except as may be necessary to comply with
                the notice requirements in Section 3.4).

                2.4. Subsequent Licenses

                No Contributor makes additional grants as a result of Your choice to
                distribute the Covered Software under a subsequent version of this
                License (see Section 10.2) or under the terms of a Secondary License (if
                permitted under the terms of Section 3.3).

                2.5. Representation

                Each Contributor represents that the Contributor believes its
                Contributions are its original creation(s) or it has sufficient rights
                to grant the rights to its Contributions conveyed by this License.

                2.6. Fair Use

                This License is not intended to limit any rights You have under
                applicable copyright doctrines of fair use, fair dealing, or other
                equivalents.

                2.7. Conditions

                Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted
                in Section 2.1.

                3. Responsibilities
                -------------------

                3.1. Distribution of Source Form

                All distribution of Covered Software in Source Code Form, including any
                Modifications that You create or to which You contribute, must be under
                the terms of this License. You must inform recipients that the Source
                Code Form of the Covered Software is governed by the terms of this
                License, and how they can obtain a copy of this License. You may not
                attempt to alter or restrict the recipients' rights in the Source Code
                Form.

                3.2. Distribution of Executable Form

                If You distribute Covered Software in Executable Form then:

                (a) such Covered Software must also be made available in Source Code
                    Form, as described in Section 3.1, and You must inform recipients of
                    the Executable Form how they can obtain a copy of such Source Code
                    Form by reasonable means in a timely manner, at a charge no more
                    than the cost of distribution to the recipient; and

                (b) You may distribute such Executable Form under the terms of this
                    License, or sublicense it under different terms, provided that the
                    license for the Executable Form does not attempt to limit or alter
                    the recipients' rights in the Source Code Form under this License.

                3.3. Distribution of a Larger Work

                You may create and distribute a Larger Work under terms of Your choice,
                provided that You also comply with the requirements of this License for
                the Covered Software. If the Larger Work is a combination of Covered
                Software with a work governed by one or more Secondary Licenses, and the
                Covered Software is not Incompatible With Secondary Licenses, this
                License permits You to additionally distribute such Covered Software
                under the terms of such Secondary License(s), so that the recipient of
                the Larger Work may, at their option, further distribute the Covered
                Software under the terms of either this License or such Secondary
                License(s).

                3.4. Notices

                You may not remove or alter the substance of any license notices
                (including copyright notices, patent notices, disclaimers of warranty,
                or limitations of liability) contained within the Source Code Form of
                the Covered Software, except that You may alter any license notices to
                the extent required to remedy known factual inaccuracies.

                3.5. Application of Additional Terms

                You may choose to offer, and to charge a fee for, warranty, support,
                indemnity or liability obligations to one or more recipients of Covered
                Software. However, You may do so only on Your own behalf, and not on
                behalf of any Contributor. You must make it absolutely clear that any
                such warranty, support, indemnity, or liability obligation is offered by
                You alone, and You hereby agree to indemnify every Contributor for any
                liability incurred by such Contributor as a result of warranty, support,
                indemnity or liability terms You offer. You may include additional
                disclaimers of warranty and limitations of liability specific to any
                jurisdiction.

                4. Inability to Comply Due to Statute or Regulation
                ---------------------------------------------------

                If it is impossible for You to comply with any of the terms of this
                License with respect to some or all of the Covered Software due to
                statute, judicial order, or regulation then You must: (a) comply with
                the terms of this License to the maximum extent possible; and (b)
                describe the limitations and the code they affect. Such description must
                be placed in a text file included with all distributions of the Covered
                Software under this License. Except to the extent prohibited by statute
                or regulation, such description must be sufficiently detailed for a
                recipient of ordinary skill to be able to understand it.

                5. Termination
                --------------

                5.1. The rights granted under this License will terminate automatically
                if You fail to comply with any of its terms. However, if You become
                compliant, then the rights granted under this License from a particular
                Contributor are reinstated (a) provisionally, unless and until such
                Contributor explicitly and finally terminates Your grants, and (b) on an
                ongoing basis, if such Contributor fails to notify You of the
                non-compliance by some reasonable means prior to 60 days after You have
                come back into compliance. Moreover, Your grants from a particular
                Contributor are reinstated on an ongoing basis if such Contributor
                notifies You of the non-compliance by some reasonable means, this is the
                first time You have received notice of non-compliance with this License
                from such Contributor, and You become compliant prior to 30 days after
                Your receipt of the notice.

                5.2. If You initiate litigation against any entity by asserting a patent
                infringement claim (excluding declaratory judgment actions,
                counter-claims, and cross-claims) alleging that a Contributor Version
                directly or indirectly infringes any patent, then the rights granted to
                You by any and all Contributors for the Covered Software under Section
                2.1 of this License shall terminate.

                5.3. In the event of termination under Sections 5.1 or 5.2 above, all
                end user license agreements (excluding distributors and resellers) which
                have been validly granted by You or Your distributors under this License
                prior to termination shall survive termination.

                8. Litigation
                -------------

                Any litigation relating to this License may be brought only in the
                courts of a jurisdiction where the defendant maintains its principal
                place of business and such litigation shall be governed by laws of that
                jurisdiction, without reference to its conflict-of-law provisions.
                Nothing in this Section shall prevent a party's ability to bring
                cross-claims or counter-claims.

                9. Miscellaneous
                ----------------

                This License represents the complete agreement concerning the subject
                matter hereof. If any provision of this License is held to be
                unenforceable, such provision shall be reformed only to the extent
                necessary to make it enforceable. Any law or regulation which provides
                that the language of a contract shall be construed against the drafter
                shall not be used to construe this License against a Contributor.

                10. Versions of the License
                ---------------------------

                10.1. New Versions

                Mozilla Foundation is the license steward. Except as provided in Section
                10.3, no one other than the license steward has the right to modify or
                publish new versions of this License. Each version will be given a
                distinguishing version number.

                10.2. Effect of New Versions

                You may distribute the Covered Software under the terms of the version
                of the License under which You originally received the Covered Software,
                or under the terms of any subsequent version published by the license
                steward.

                10.3. Modified Versions

                If you create software not governed by this License, and you want to
                create a new license for such software, you may create and use a
                modified version of this License if you rename the license and remove
                any references to the name of the license steward (except to note that
                such modified license differs from this License).

                10.4. Distributing Source Code Form that is Incompatible With Secondary
                Licenses

                If You choose to distribute Source Code Form that is Incompatible With
                Secondary Licenses under the terms of this version of the License, the
                notice described in Exhibit B of this License must be attached.

                Exhibit A - Source Code Form License Notice
                -------------------------------------------

                file, then You may include the notice in a location (such as a LICENSE
                file in a relevant directory) where a recipient would be likely to look
                for such a notice.

                You may add additional accurate notices of copyright ownership.

                GNU LESSER GENERAL PUBLIC LICENSE
                Version 3, 29 June 2007

                Copyright © 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.

                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.
