   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

       1. Definitions.

          "License" shall mean the terms and conditions for use, reproduction,
          and distribution as defined by Sections 1 through 9 of this document.

          "Licensor" shall mean the copyright owner or entity authorized by
          the copyright owner that is granting the License.

          "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.

          "You" (or "Your") shall mean an individual or Legal Entity
          exercising permissions granted by this License.

          "Source" form shall mean the preferred form for making modifications,
          including but not limited to software source code, documentation
          source, and configuration files.

          "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.

          "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).

          "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.

          "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."

          "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.

      2. Grant of Copyright License. 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.

      3. Grant of Patent License. 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.

      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.

            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.

      "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

      of this License, Derivative Works shall not include works that remain

      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.

   3. Grant of Patent License. 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,

      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

          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.

Creative Commons Corporation ("Creative Commons") is not a law firm and
does not provide legal services or legal advice. Distribution of
Creative Commons public licenses does not create a lawyer-client or
other relationship. Creative Commons makes its licenses and related
information available on an "as-is" basis. Creative Commons gives no
warranties regarding its licenses, any material licensed under their
terms and conditions, or any related information. Creative Commons
disclaims all liability for damages resulting from their use to the

Using Creative Commons Public Licenses

Creative Commons public licenses provide a standard set of terms and
conditions that creators and other rights holders may use to share
original works of authorship and other material subject to copyright
and certain other rights specified in the public license below. The
following considerations are for informational purposes only, are not
exhaustive, and do not form part of our licenses.

     Considerations for licensors: Our public licenses are
     intended for use by those authorized to give the public
     permission to use material in ways otherwise restricted by
     copyright and certain other rights. Our licenses are
     irrevocable. Licensors should read and understand the terms
     and conditions of the license they choose before applying it.
     Licensors should also secure all rights necessary before
     applying our licenses so that the public can reuse the
     material as expected. Licensors should clearly mark any
     material not subject to the license. This includes other CC-
     licensed material, or material used under an exception or
     limitation to copyright. More considerations for licensors:
	wiki.creativecommons.org/Considerations_for_licensors

     Considerations for the public: By using one of our public
     licenses, a licensor grants the public permission to use the
     licensed material under specified terms and conditions. If
     the licensor's permission is not necessary for any reason--for
     example, because of any applicable exception or limitation to
     copyright--then that use is not regulated by the license. Our
     licenses grant only permissions under copyright and certain
     other rights that a licensor has authority to grant. Use of
     the licensed material may still be restricted for other
     reasons, including because others have copyright or other
     rights in the material. A licensor may make special requests,
     such as asking that all changes be marked or described.
     Although not required by our licenses, you are encouraged to
     respect those requests where reasonable. More_considerations
     for the public:

License

By exercising the Licensed Rights (defined below), You accept and agree
to be bound by the terms and conditions of this Creative Commons
Attribution-NonCommercial 4.0 International Public License ("Public
License"). To the extent this Public License may be interpreted as a
contract, You are granted the Licensed Rights in consideration of Your

making the Licensed Material available under these terms and
conditions.

     Rights that is derived from or based upon the Licensed Material
     and in which the Licensed Material is translated, altered,

     Licensor. For purposes of this Public License, where the Licensed
     Material is a musical work, performance, or sound recording,
     Adapted Material is always produced where the Licensed Material is
     synched in timed relation with a moving image.

     and Similar Rights in Your contributions to Adapted Material in
     accordance with the terms and conditions of this Public License.

     closely related to copyright including, without limitation,
     performance, broadcast, sound recording, and Sui Generis Database
     Rights, without regard to how the rights are labeled or
     categorized. For purposes of this Public License, the rights
     specified in Section 2(b)(1)-(2) are not Copyright and Similar
     Rights.
  d. Effective Technological Measures means those measures that, in the
     absence of proper authority, may not be circumvented under laws
     fulfilling obligations under Article 11 of the WIPO Copyright
     Treaty adopted on December 20, 1996, and/or similar international
     agreements.

  e. Exceptions and Limitations means fair use, fair dealing, and/or
     any other exception or limitation to Copyright and Similar Rights
     that applies to Your use of the Licensed Material.

  f. Licensed Material means the artistic or literary work, database,
     or other material to which the Licensor applied this Public
     License.

  g. Licensed Rights means the rights granted to You subject to the
     terms and conditions of this Public License, which are limited to
     all Copyright and Similar Rights that apply to Your use of the
     Licensed Material and that the Licensor has authority to license.

  h. Licensor means the individual(s) or entity(ies) granting rights
     under this Public License.

  i. NonCommercial means not primarily intended for or directed towards
     commercial advantage or monetary compensation. For purposes of
     this Public License, the exchange of the Licensed Material for
     other material subject to Copyright and Similar Rights by digital
     file-sharing or similar means is NonCommercial provided there is
     no payment of monetary compensation in connection with the
     exchange.

  j. Share means to provide material to the public by any means or
     process that requires permission under the Licensed Rights, such
     as reproduction, public display, public performance, distribution,
     dissemination, communication, or importation, and to make material
     available to the public including in ways that members of the
     public may access the material from a place and at a time
     individually chosen by them.

  k. Sui Generis Database Rights means rights other than copyright
     resulting from Directive 96/9/EC of the European Parliament and of
     the Council of 11 March 1996 on the legal protection of databases,
     as amended and/or succeeded, as well as other essentially
     equivalent rights anywhere in the world.

  l. You means the individual or entity exercising the Licensed Rights
     under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

  a. License grant.

       1. Subject to the terms and conditions of this Public License,
          the Licensor hereby grants You a worldwide, royalty-free,
          non-sublicensable, non-exclusive, irrevocable license to
          exercise the Licensed Rights in the Licensed Material to:

            a. reproduce and Share the Licensed Material, in whole or
               in part, for NonCommercial purposes only; and

            b. produce, reproduce, and Share Adapted Material for
               NonCommercial purposes only.

       2. Exceptions and Limitations. For the avoidance of doubt, where
          Exceptions and Limitations apply to Your use, this Public
          License does not apply, and You do not need to comply with
          its terms and conditions.

       3. Term. The term of this Public License is specified in Section
          6(a).

       4. Media and formats; technical modifications allowed. The
          Licensor authorizes You to exercise the Licensed Rights in
          all media and formats whether now known or hereafter created,
          and to make technical modifications necessary to do so. The
          Licensor waives and/or agrees not to assert any right or
          authority to forbid You from making technical modifications
          necessary to exercise the Licensed Rights, including
          technical modifications necessary to circumvent Effective
          Technological Measures. For purposes of this Public License,
          simply making modifications authorized by this Section 2(a)
          (4) never produces Adapted Material.

       5. Downstream recipients.

            a. Offer from the Licensor -- Licensed Material. Every
               recipient of the Licensed Material automatically
               receives an offer from the Licensor to exercise the
               Licensed Rights under the terms and conditions of this
               Public License.

            b. No downstream restrictions. You may not offer or impose
               any additional or different terms or conditions on, or
               apply any Effective Technological Measures to, the
               Licensed Material if doing so restricts exercise of the
               Licensed Rights by any recipient of the Licensed
               Material.

       6. No endorsement. Nothing in this Public License constitutes or
          may be construed as permission to assert or imply that You
          are, or that Your use of the Licensed Material is, connected
          with, or sponsored, endorsed, or granted official status by,
          the Licensor or others designated to receive attribution as
          provided in Section 3(a)(1)(A)(i).

  b. Other rights.

       1. Moral rights, such as the right of integrity, are not
          licensed under this Public License, nor are publicity,
          privacy, and/or other similar personality rights; however, to
          the extent possible, the Licensor waives and/or agrees not to
          assert any such rights held by the Licensor to the limited
          extent necessary to allow You to exercise the Licensed
          Rights, but not otherwise.

       2. Patent and trademark rights are not licensed under this
          Public License.

       3. To the extent possible, the Licensor waives any right to
          collect royalties from You for the exercise of the Licensed
          Rights, whether directly or through a collecting society
          under any voluntary or waivable statutory or compulsory
          licensing scheme. In all other cases the Licensor expressly
          reserves any right to collect such royalties, including when
          the Licensed Material is used other than for NonCommercial
          purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the
following conditions.

  a. Attribution.

       1. If You Share the Licensed Material (including in modified
          form), You must:

            a. retain the following if it is supplied by the Licensor
               with the Licensed Material:

                 i. identification of the creator(s) of the Licensed
                    Material and any others designated to receive
                    attribution, in any reasonable manner requested by
                    the Licensor (including by pseudonym if
                    designated);

                ii. a copyright notice;

               iii. a notice that refers to this Public License;

                iv. a notice that refers to the disclaimer of
                    warranties;

                 v. a URI or hyperlink to the Licensed Material to the
                    extent reasonably practicable;

            b. indicate if You modified the Licensed Material and
               retain an indication of any previous modifications; and

            c. indicate the Licensed Material is licensed under this
               Public License, and include the text of, or the URI or
               hyperlink to, this Public License.

       2. You may satisfy the conditions in Section 3(a)(1) in any
          reasonable manner based on the medium, means, and context in
          which You Share the Licensed Material. For example, it may be
          reasonable to satisfy the conditions by providing a URI or
          hyperlink to a resource that includes the required
          information.

       3. If requested by the Licensor, You must remove any of the
          information required by Section 3(a)(1)(A) to the extent
          reasonably practicable.

       4. If You Share Adapted Material You produce, the Adapter's
          License You apply must not prevent recipients of the Adapted
          Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:

  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
     to extract, reuse, reproduce, and Share all or a substantial
     portion of the contents of the database for NonCommercial purposes
     only;

  b. if You include all or a substantial portion of the database
     contents in a database in which You have Sui Generis Database
     Rights, then the database in which You have Sui Generis Database
     Rights (but not its individual contents) is Adapted Material; and

  c. You must comply with the conditions in Section 3(a) if You Share
     all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

  c. The disclaimer of warranties and limitation of liability provided
     above shall be interpreted in a manner that, to the extent
     possible, most closely approximates an absolute disclaimer and
     waiver of all liability.

Section 6 -- Term and Termination.

  a. This Public License applies for the term of the Copyright and
     Similar Rights licensed here. However, if You fail to comply with
     this Public License, then Your rights under this Public License
     terminate automatically.

  b. Where Your right to use the Licensed Material has terminated under
     Section 6(a), it reinstates:

       1. automatically as of the date the violation is cured, provided
          it is cured within 30 days of Your discovery of the
          violation; or

       2. upon express reinstatement by the Licensor.

     For the avoidance of doubt, this Section 6(b) does not affect any
     right the Licensor may have to seek remedies for Your violations
     of this Public License.

  c. For the avoidance of doubt, the Licensor may also offer the
     Licensed Material under separate terms or conditions or stop
     distributing the Licensed Material at any time; however, doing so
     will not terminate this Public License.

  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
     License.

Section 7 -- Other Terms and Conditions.

  a. The Licensor shall not be bound by any additional or different
     terms or conditions communicated by You unless expressly agreed.

  b. Any arrangements, understandings, or agreements regarding the
     Licensed Material not stated herein are separate from and
     independent of the terms and conditions of this Public License.

Section 8 -- Interpretation.

  a. For the avoidance of doubt, this Public License does not, and
     shall not be interpreted to, reduce, limit, restrict, or impose
     conditions on any use of the Licensed Material that could lawfully
     be made without permission under this Public License.

  b. To the extent possible, if any provision of this Public License is
     deemed unenforceable, it shall be automatically reformed to the
     minimum extent necessary to make it enforceable. If the provision
     cannot be reformed, it shall be severed from this Public License
     without affecting the enforceability of the remaining terms and
     conditions.

  c. No term or condition of this Public License will be waived and no
     failure to comply consented to unless expressly agreed to by the
     Licensor.

  d. Nothing in this Public License constitutes or may be interpreted
     as a limitation upon, or waiver of, any privileges and immunities
     that apply to the Licensor or You, including from the legal
     processes of any jurisdiction or authority.

Using Creative Commons Public Licenses

Creative Commons public licenses provide a standard set of terms and
conditions that creators and other rights holders may use to share
original works of authorship and other material subject to copyright
and certain other rights specified in the public license below. The
following considerations are for informational purposes only, are not
exhaustive, and do not form part of our licenses.

     Considerations for licensors: Our public licenses are
     intended for use by those authorized to give the public
     permission to use material in ways otherwise restricted by
     copyright and certain other rights. Our licenses are
     irrevocable. Licensors should read and understand the terms
     and conditions of the license they choose before applying it.
     Licensors should also secure all rights necessary before
     applying our licenses so that the public can reuse the
     material as expected. Licensors should clearly mark any
     material not subject to the license. This includes other CC-
     licensed material, or material used under an exception or
     limitation to copyright. More considerations for licensors:
	wiki.creativecommons.org/Considerations_for_licensors

     Considerations for the public: By using one of our public
     licenses, a licensor grants the public permission to use the
     licensed material under specified terms and conditions. If
     the licensor's permission is not necessary for any reason--for
     example, because of any applicable exception or limitation to
     copyright--then that use is not regulated by the license. Our
     licenses grant only permissions under copyright and certain
     other rights that a licensor has authority to grant. Use of
     the licensed material may still be restricted for other
     reasons, including because others have copyright or other
     rights in the material. A licensor may make special requests,
     such as asking that all changes be marked or described.
     Although not required by our licenses, you are encouraged to
     respect those requests where reasonable. More_considerations

License

By exercising the Licensed Rights (defined below), You accept and agree
to be bound by the terms and conditions of this Creative Commons
Attribution-NonCommercial 4.0 International Public License ("Public
License"). To the extent this Public License may be interpreted as a
contract, You are granted the Licensed Rights in consideration of Your
acceptance of these terms and conditions, and the Licensor grants You
such rights in consideration of benefits the Licensor receives from
making the Licensed Material available under these terms and
conditions.

Section 1 -- Definitions.

  a. Adapted Material means material subject to Copyright and Similar
     Rights that is derived from or based upon the Licensed Material
     and in which the Licensed Material is translated, altered,
     arranged, transformed, or otherwise modified in a manner requiring
     permission under the Copyright and Similar Rights held by the
     Licensor. For purposes of this Public License, where the Licensed
     Material is a musical work, performance, or sound recording,
     Adapted Material is always produced where the Licensed Material is
     synched in timed relation with a moving image.

  b. Adapter's License means the license You apply to Your Copyright
     and Similar Rights in Your contributions to Adapted Material in
     accordance with the terms and conditions of this Public License.

  c. Copyright and Similar Rights means copyright and/or similar rights
     closely related to copyright including, without limitation,
     performance, broadcast, sound recording, and Sui Generis Database
     Rights, without regard to how the rights are labeled or
     categorized. For purposes of this Public License, the rights
     specified in Section 2(b)(1)-(2) are not Copyright and Similar
     Rights.
  d. Effective Technological Measures means those measures that, in the
     absence of proper authority, may not be circumvented under laws
     fulfilling obligations under Article 11 of the WIPO Copyright
     Treaty adopted on December 20, 1996, and/or similar international
     agreements.

  e. Exceptions and Limitations means fair use, fair dealing, and/or
     any other exception or limitation to Copyright and Similar Rights
     that applies to Your use of the Licensed Material.

  f. Licensed Material means the artistic or literary work, database,
     or other material to which the Licensor applied this Public
     License.

  g. Licensed Rights means the rights granted to You subject to the
     terms and conditions of this Public License, which are limited to
     all Copyright and Similar Rights that apply to Your use of the
     Licensed Material and that the Licensor has authority to license.

  h. Licensor means the individual(s) or entity(ies) granting rights
     under this Public License.

  i. NonCommercial means not primarily intended for or directed towards
     commercial advantage or monetary compensation. For purposes of
     this Public License, the exchange of the Licensed Material for
     other material subject to Copyright and Similar Rights by digital
     file-sharing or similar means is NonCommercial provided there is
     no payment of monetary compensation in connection with the
     exchange.

  j. Share means to provide material to the public by any means or
     process that requires permission under the Licensed Rights, such
     as reproduction, public display, public performance, distribution,
     dissemination, communication, or importation, and to make material
     available to the public including in ways that members of the
     public may access the material from a place and at a time
     individually chosen by them.

  k. Sui Generis Database Rights means rights other than copyright
     resulting from Directive 96/9/EC of the European Parliament and of
     the Council of 11 March 1996 on the legal protection of databases,
     as amended and/or succeeded, as well as other essentially
     equivalent rights anywhere in the world.

  l. You means the individual or entity exercising the Licensed Rights
     under this Public License. Your has a corresponding meaning.

Section 2 -- Scope.

  a. License grant.

       1. Subject to the terms and conditions of this Public License,
          the Licensor hereby grants You a worldwide, royalty-free,
          non-sublicensable, non-exclusive, irrevocable license to
          exercise the Licensed Rights in the Licensed Material to:

            a. reproduce and Share the Licensed Material, in whole or
               in part, for NonCommercial purposes only; and

            b. produce, reproduce, and Share Adapted Material for
               NonCommercial purposes only.

       2. Exceptions and Limitations. For the avoidance of doubt, where
          Exceptions and Limitations apply to Your use, this Public
          License does not apply, and You do not need to comply with
          its terms and conditions.

       3. Term. The term of this Public License is specified in Section
          6(a).

       4. Media and formats; technical modifications allowed. The
          Licensor authorizes You to exercise the Licensed Rights in
          all media and formats whether now known or hereafter created,
          and to make technical modifications necessary to do so. The
          Licensor waives and/or agrees not to assert any right or
          authority to forbid You from making technical modifications
          necessary to exercise the Licensed Rights, including
          technical modifications necessary to circumvent Effective
          Technological Measures. For purposes of this Public License,
          simply making modifications authorized by this Section 2(a)
          (4) never produces Adapted Material.

       5. Downstream recipients.

            a. Offer from the Licensor -- Licensed Material. Every
               recipient of the Licensed Material automatically
               receives an offer from the Licensor to exercise the
               Licensed Rights under the terms and conditions of this
               Public License.

            b. No downstream restrictions. You may not offer or impose
               any additional or different terms or conditions on, or
               apply any Effective Technological Measures to, the
               Licensed Material if doing so restricts exercise of the
               Licensed Rights by any recipient of the Licensed
               Material.

       6. No endorsement. Nothing in this Public License constitutes or
          may be construed as permission to assert or imply that You
          are, or that Your use of the Licensed Material is, connected
          with, or sponsored, endorsed, or granted official status by,
          the Licensor or others designated to receive attribution as
          provided in Section 3(a)(1)(A)(i).

  b. Other rights.

       1. Moral rights, such as the right of integrity, are not
          licensed under this Public License, nor are publicity,
          privacy, and/or other similar personality rights; however, to
          the extent possible, the Licensor waives and/or agrees not to
          assert any such rights held by the Licensor to the limited
          extent necessary to allow You to exercise the Licensed
          Rights, but not otherwise.

       2. Patent and trademark rights are not licensed under this
          Public License.

       3. To the extent possible, the Licensor waives any right to
          collect royalties from You for the exercise of the Licensed
          Rights, whether directly or through a collecting society
          under any voluntary or waivable statutory or compulsory
          licensing scheme. In all other cases the Licensor expressly
          reserves any right to collect such royalties, including when
          the Licensed Material is used other than for NonCommercial
          purposes.

Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the
following conditions.

  a. Attribution.

       1. If You Share the Licensed Material (including in modified
          form), You must:

            a. retain the following if it is supplied by the Licensor
               with the Licensed Material:

                 i. identification of the creator(s) of the Licensed
                    Material and any others designated to receive
                    attribution, in any reasonable manner requested by
                    the Licensor (including by pseudonym if
                    designated);

                ii. a copyright notice;

               iii. a notice that refers to this Public License;

                iv. a notice that refers to the disclaimer of
                    warranties;

                 v. a URI or hyperlink to the Licensed Material to the
                    extent reasonably practicable;

            b. indicate if You modified the Licensed Material and
               retain an indication of any previous modifications; and

            c. indicate the Licensed Material is licensed under this
               Public License, and include the text of, or the URI or
               hyperlink to, this Public License.

       2. You may satisfy the conditions in Section 3(a)(1) in any
          reasonable manner based on the medium, means, and context in
          which You Share the Licensed Material. For example, it may be
          reasonable to satisfy the conditions by providing a URI or
          hyperlink to a resource that includes the required
          information.

       3. If requested by the Licensor, You must remove any of the
          information required by Section 3(a)(1)(A) to the extent
          reasonably practicable.

       4. If You Share Adapted Material You produce, the Adapter's
          License You apply must not prevent recipients of the Adapted
          Material from complying with this Public License.

Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:

  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
     to extract, reuse, reproduce, and Share all or a substantial
     portion of the contents of the database for NonCommercial purposes
     only;

  b. if You include all or a substantial portion of the database
     contents in a database in which You have Sui Generis Database
     Rights, then the database in which You have Sui Generis Database
     Rights (but not its individual contents) is Adapted Material; and

  c. You must comply with the conditions in Section 3(a) if You Share
     all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.

Section 5 -- Disclaimer of Warranties and Limitation of Liability.

  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

  c. The disclaimer of warranties and limitation of liability provided
     above shall be interpreted in a manner that, to the extent
     possible, most closely approximates an absolute disclaimer and
     waiver of all liability.

Section 6 -- Term and Termination.

  a. This Public License applies for the term of the Copyright and
     Similar Rights licensed here. However, if You fail to comply with
     this Public License, then Your rights under this Public License
     terminate automatically.

  b. Where Your right to use the Licensed Material has terminated under
     Section 6(a), it reinstates:

       1. automatically as of the date the violation is cured, provided
          it is cured within 30 days of Your discovery of the
          violation; or

       2. upon express reinstatement by the Licensor.

     For the avoidance of doubt, this Section 6(b) does not affect any
     right the Licensor may have to seek remedies for Your violations
     of this Public License.

  c. For the avoidance of doubt, the Licensor may also offer the
     Licensed Material under separate terms or conditions or stop
     distributing the Licensed Material at any time; however, doing so
     will not terminate this Public License.

  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
     License.

Section 7 -- Other Terms and Conditions.

  a. The Licensor shall not be bound by any additional or different

     shall not be interpreted to, reduce, limit, restrict, or impose
     conditions on any use of the Licensed Material that could lawfully
     be made without permission under this Public License.

  b. To the extent possible, if any provision of this Public License is
     deemed unenforceable, it shall be automatically reformed to the
     minimum extent necessary to make it enforceable. If the provision
     cannot be reformed, it shall be severed from this Public License
     without affecting the enforceability of the remaining terms and
     conditions.

  c. No term or condition of this Public License will be waived and no
     failure to comply consented to unless expressly agreed to by the
     Licensor.

  d. Nothing in this Public License constitutes or may be interpreted
     as a limitation upon, or waiver of, any privileges and immunities
     that apply to the Licensor or You, including from the legal
     processes of any jurisdiction or authority.

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the

         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.

          source, and configuration files.

          "Object" form shall mean any form resulting from mechanical
          transformation or translation of a Source form, including but

          "Work" shall mean the work of authorship, whether in Source or

          copyright notice that is included in or attached to the work
          (an example is provided in the Appendix below).

          "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.

          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions

          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,

          "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.

      2. Grant of Copyright License. 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.

      3. Grant of Patent License. Subject to the terms and conditions of

         (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.

      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

             stating that You changed the files; and

             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.

      "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.

      "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).

      "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.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions

      the copyright owner. For the purposes of this definition, "submitted"

      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.

   3. Grant of Patent License. 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.

   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.

      "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

      represent, as a whole, an original work of authorship. For the purposes

      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.

   3. Grant of Patent License. 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,

      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) 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.

   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.

          "Object" form shall mean any form resulting from mechanical
          transformation or translation of a Source form, including but

          "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.

          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions

          subsequently incorporated within the Work.

         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

             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

             within such NOTICE file, excluding those notices that do not
             pertain to any part of the Derivative Works, in at least one

             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

             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,

         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,

         incurred by, or claims asserted against, such Contributor by reason
         of your accepting any such warranty or additional liability.

         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.

      "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.

      "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).

      "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.

      "Contribution" shall mean any work of authorship, including
      the original version of the Work and any modifications or additions

      the copyright owner. For the purposes of this definition, "submitted"

      "Contributor" shall mean Licensor and any individual or Legal Entity
      on behalf of whom a Contribution has been received by Licensor and

      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.

   3. Grant of Patent License. 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,

      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

          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.

      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.

         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

         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,

         origin of the Work and reproducing the content of the NOTICE file.

         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,

         incurred by, or claims asserted against, such Contributor by reason
         of your accepting any such warranty or additional liability.

   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION

       1. Definitions.

          "License" shall mean the terms and conditions for use, reproduction,
          and distribution as defined by Sections 1 through 9 of this document.

          "Licensor" shall mean the copyright owner or entity authorized by
          the copyright owner that is granting the License.

          "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.

          "You" (or "Your") shall mean an individual or Legal Entity
          exercising permissions granted by this License.

          "Source" form shall mean the preferred form for making modifications,
          including but not limited to software source code, documentation
          source, and configuration files.

          "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.

          "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).

          "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.

          "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."

          "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.

      2. Grant of Copyright License. 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.

      3. Grant of Patent License. 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.

      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.

          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.

          exercising permissions granted by this License.

          "Source" form shall mean the preferred form for making modifications,

          source, and configuration files.

          "Object" form shall mean any form resulting from mechanical
          transformation or translation of a Source form, including but

          "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).

          "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.

          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions

          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,

          "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.

      2. Grant of Copyright License. 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.

      3. Grant of Patent License. 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.

      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.

Creative Commons Corporation ("Creative Commons") is not a law firm and
does not provide legal services or legal advice. Distribution of
Creative Commons public licenses does not create a lawyer-client or
other relationship. Creative Commons makes its licenses and related

Using Creative Commons Public Licenses

Creative Commons public licenses provide a standard set of terms and
conditions that creators and other rights holders may use to share
original works of authorship and other material subject to copyright
and certain other rights specified in the public license below. The
following considerations are for informational purposes only, are not
exhaustive, and do not form part of our licenses.

     Considerations for licensors: Our public licenses are
     intended for use by those authorized to give the public
     permission to use material in ways otherwise restricted by
     copyright and certain other rights. Our licenses are
     irrevocable. Licensors should read and understand the terms
     and conditions of the license they choose before applying it.
     Licensors should also secure all rights necessary before
     applying our licenses so that the public can reuse the
     material as expected. Licensors should clearly mark any
     material not subject to the license. This includes other CC-
     licensed material, or material used under an exception or
     limitation to copyright. More considerations for licensors:
    wiki.creativecommons.org/Considerations_for_licensors

     Considerations for the public: By using one of our public
     licenses, a licensor grants the public permission to use the
     licensed material under specified terms and conditions. If
     the licensor's permission is not necessary for any reason--for
     example, because of any applicable exception or limitation to
     copyright--then that use is not regulated by the license. Our
     licenses grant only permissions under copyright and certain
     other rights that a licensor has authority to grant. Use of
     the licensed material may still be restricted for other
     reasons, including because others have copyright or other
     rights in the material. A licensor may make special requests,
     such as asking that all changes be marked or described.
     Although not required by our licenses, you are encouraged to
     respect those requests where reasonable. More considerations
     for the public:

Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International
Public License

By exercising the Licensed Rights (defined below), You accept and agree
to be bound by the terms and conditions of this Creative Commons
Attribution-NonCommercial-ShareAlike 4.0 International Public License
("Public License"). To the extent this Public License may be
interpreted as a contract, You are granted the Licensed Rights in
consideration of Your acceptance of these terms and conditions, and the
Licensor grants You such rights in consideration of benefits the
Licensor receives from making the Licensed Material available under
these terms and conditions.


Section 1 -- Definitions.

  a. Adapted Material means material subject to Copyright and Similar
     Rights that is derived from or based upon the Licensed Material
     and in which the Licensed Material is translated, altered,
     arranged, transformed, or otherwise modified in a manner requiring
     permission under the Copyright and Similar Rights held by the
     Licensor. For purposes of this Public License, where the Licensed
     Material is a musical work, performance, or sound recording,
     Adapted Material is always produced where the Licensed Material is
     synched in timed relation with a moving image.

  b. Adapter's License means the license You apply to Your Copyright
     and Similar Rights in Your contributions to Adapted Material in
     accordance with the terms and conditions of this Public License.

  c. BY-NC-SA Compatible License means a license listed at
     creativecommons.org/compatiblelicenses, approved by Creative
     Commons as essentially the equivalent of this Public License.

  d. Copyright and Similar Rights means copyright and/or similar rights
     closely related to copyright including, without limitation,
     performance, broadcast, sound recording, and Sui Generis Database
     Rights, without regard to how the rights are labeled or
     categorized. For purposes of this Public License, the rights
     specified in Section 2(b)(1)-(2) are not Copyright and Similar
     Rights.

  e. Effective Technological Measures means those measures that, in the
     absence of proper authority, may not be circumvented under laws
     fulfilling obligations under Article 11 of the WIPO Copyright
     Treaty adopted on December 20, 1996, and/or similar international
     agreements.

  f. Exceptions and Limitations means fair use, fair dealing, and/or
     any other exception or limitation to Copyright and Similar Rights
     that applies to Your use of the Licensed Material.

  g. License Elements means the license attributes listed in the name
     of a Creative Commons Public License. The License Elements of this
     Public License are Attribution, NonCommercial, and ShareAlike.

  h. Licensed Material means the artistic or literary work, database,
     or other material to which the Licensor applied this Public
     License.

  i. Licensed Rights means the rights granted to You subject to the
     terms and conditions of this Public License, which are limited to
     all Copyright and Similar Rights that apply to Your use of the
     Licensed Material and that the Licensor has authority to license.

  j. Licensor means the individual(s) or entity(ies) granting rights
     under this Public License.

  k. NonCommercial means not primarily intended for or directed towards
     commercial advantage or monetary compensation. For purposes of
     this Public License, the exchange of the Licensed Material for
     other material subject to Copyright and Similar Rights by digital
     file-sharing or similar means is NonCommercial provided there is
     no payment of monetary compensation in connection with the
     exchange.

  l. Share means to provide material to the public by any means or
     process that requires permission under the Licensed Rights, such
     as reproduction, public display, public performance, distribution,
     dissemination, communication, or importation, and to make material
     available to the public including in ways that members of the
     public may access the material from a place and at a time
     individually chosen by them.

  m. Sui Generis Database Rights means rights other than copyright
     resulting from Directive 96/9/EC of the European Parliament and of
     the Council of 11 March 1996 on the legal protection of databases,
     as amended and/or succeeded, as well as other essentially
     equivalent rights anywhere in the world.

  n. You means the individual or entity exercising the Licensed Rights
     under this Public License. Your has a corresponding meaning.


Section 2 -- Scope.

  a. License grant.

       1. Subject to the terms and conditions of this Public License,
          the Licensor hereby grants You a worldwide, royalty-free,
          non-sublicensable, non-exclusive, irrevocable license to
          exercise the Licensed Rights in the Licensed Material to:

            a. reproduce and Share the Licensed Material, in whole or
               in part, for NonCommercial purposes only; and

            b. produce, reproduce, and Share Adapted Material for
               NonCommercial purposes only.

       2. Exceptions and Limitations. For the avoidance of doubt, where
          Exceptions and Limitations apply to Your use, this Public
          License does not apply, and You do not need to comply with
          its terms and conditions.

       3. Term. The term of this Public License is specified in Section
          6(a).

       4. Media and formats; technical modifications allowed. The
          Licensor authorizes You to exercise the Licensed Rights in
          all media and formats whether now known or hereafter created,
          and to make technical modifications necessary to do so. The
          Licensor waives and/or agrees not to assert any right or
          authority to forbid You from making technical modifications
          necessary to exercise the Licensed Rights, including
          technical modifications necessary to circumvent Effective
          Technological Measures. For purposes of this Public License,
          simply making modifications authorized by this Section 2(a)
          (4) never produces Adapted Material.

       5. Downstream recipients.

            a. Offer from the Licensor -- Licensed Material. Every
               recipient of the Licensed Material automatically
               receives an offer from the Licensor to exercise the
               Licensed Rights under the terms and conditions of this
               Public License.

            b. Additional offer from the Licensor -- Adapted Material.
               Every recipient of Adapted Material from You
               automatically receives an offer from the Licensor to
               exercise the Licensed Rights in the Adapted Material
               under the conditions of the Adapter's License You apply.

            c. No downstream restrictions. You may not offer or impose
               any additional or different terms or conditions on, or
               apply any Effective Technological Measures to, the
               Licensed Material if doing so restricts exercise of the
               Licensed Rights by any recipient of the Licensed
               Material.

       6. No endorsement. Nothing in this Public License constitutes or
          may be construed as permission to assert or imply that You
          are, or that Your use of the Licensed Material is, connected
          with, or sponsored, endorsed, or granted official status by,
          the Licensor or others designated to receive attribution as
          provided in Section 3(a)(1)(A)(i).

  b. Other rights.

       1. Moral rights, such as the right of integrity, are not
          licensed under this Public License, nor are publicity,
          privacy, and/or other similar personality rights; however, to
          the extent possible, the Licensor waives and/or agrees not to
          assert any such rights held by the Licensor to the limited
          extent necessary to allow You to exercise the Licensed
          Rights, but not otherwise.

       2. Patent and trademark rights are not licensed under this
          Public License.

       3. To the extent possible, the Licensor waives any right to
          collect royalties from You for the exercise of the Licensed
          Rights, whether directly or through a collecting society
          under any voluntary or waivable statutory or compulsory
          licensing scheme. In all other cases the Licensor expressly
          reserves any right to collect such royalties, including when
          the Licensed Material is used other than for NonCommercial
          purposes.


Section 3 -- License Conditions.

Your exercise of the Licensed Rights is expressly made subject to the
following conditions.

  a. Attribution.

       1. If You Share the Licensed Material (including in modified
          form), You must:

            a. retain the following if it is supplied by the Licensor
               with the Licensed Material:

                 i. identification of the creator(s) of the Licensed
                    Material and any others designated to receive
                    attribution, in any reasonable manner requested by
                    the Licensor (including by pseudonym if
                    designated);

                ii. a copyright notice;

               iii. a notice that refers to this Public License;

                iv. a notice that refers to the disclaimer of
                    warranties;

                 v. a URI or hyperlink to the Licensed Material to the
                    extent reasonably practicable;

            b. indicate if You modified the Licensed Material and
               retain an indication of any previous modifications; and

            c. indicate the Licensed Material is licensed under this
               Public License, and include the text of, or the URI or
               hyperlink to, this Public License.

       2. You may satisfy the conditions in Section 3(a)(1) in any
          reasonable manner based on the medium, means, and context in
          which You Share the Licensed Material. For example, it may be
          reasonable to satisfy the conditions by providing a URI or
          hyperlink to a resource that includes the required
          information.
       3. If requested by the Licensor, You must remove any of the
          information required by Section 3(a)(1)(A) to the extent
          reasonably practicable.

  b. ShareAlike.

     In addition to the conditions in Section 3(a), if You Share
     Adapted Material You produce, the following conditions also apply.

       1. The Adapter's License You apply must be a Creative Commons
          license with the same License Elements, this version or
          later, or a BY-NC-SA Compatible License.

       2. You must include the text of, or the URI or hyperlink to, the
          Adapter's License You apply. You may satisfy this condition
          in any reasonable manner based on the medium, means, and
          context in which You Share Adapted Material.

       3. You may not offer or impose any additional or different terms
          or conditions on, or apply any Effective Technological
          Measures to, Adapted Material that restrict exercise of the
          rights granted under the Adapter's License You apply.


Section 4 -- Sui Generis Database Rights.

Where the Licensed Rights include Sui Generis Database Rights that
apply to Your use of the Licensed Material:

  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
     to extract, reuse, reproduce, and Share all or a substantial
     portion of the contents of the database for NonCommercial purposes
     only;

  b. if You include all or a substantial portion of the database
     contents in a database in which You have Sui Generis Database
     Rights, then the database in which You have Sui Generis Database
     Rights (but not its individual contents) is Adapted Material,
     including for purposes of Section 3(b); and

  c. You must comply with the conditions in Section 3(a) if You Share
     all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section 4 supplements and does not
replace Your obligations under this Public License where the Licensed
Rights include other Copyright and Similar Rights.


Section 5 -- Disclaimer of Warranties and Limitation of Liability.

  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.

  c. The disclaimer of warranties and limitation of liability provided
     above shall be interpreted in a manner that, to the extent
     possible, most closely approximates an absolute disclaimer and
     waiver of all liability.


Section 6 -- Term and Termination.

  a. This Public License applies for the term of the Copyright and
     Similar Rights licensed here. However, if You fail to comply with
     this Public License, then Your rights under this Public License
     terminate automatically.

  b. Where Your right to use the Licensed Material has terminated under
     Section 6(a), it reinstates:

       1. automatically as of the date the violation is cured, provided
          it is cured within 30 days of Your discovery of the
          violation; or

       2. upon express reinstatement by the Licensor.

     For the avoidance of doubt, this Section 6(b) does not affect any
     right the Licensor may have to seek remedies for Your violations
     of this Public License.

  c. For the avoidance of doubt, the Licensor may also offer the
     Licensed Material under separate terms or conditions or stop
     distributing the Licensed Material at any time; however, doing so
     will not terminate this Public License.

  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
     License.


Section 7 -- Other Terms and Conditions.

  a. The Licensor shall not be bound by any additional or different
     terms or conditions communicated by You unless expressly agreed.

  b. Any arrangements, understandings, or agreements regarding the
     Licensed Material not stated herein are separate from and
     independent of the terms and conditions of this Public License.


Section 8 -- Interpretation.

  a. For the avoidance of doubt, this Public License does not, and
     shall not be interpreted to, reduce, limit, restrict, or impose
     conditions on any use of the Licensed Material that could lawfully
     be made without permission under this Public License.

  b. To the extent possible, if any provision of this Public License is
     deemed unenforceable, it shall be automatically reformed to the
     minimum extent necessary to make it enforceable. If the provision
     cannot be reformed, it shall be severed from this Public License
     without affecting the enforceability of the remaining terms and
     conditions.

  c. No term or condition of this Public License will be waived and no
     failure to comply consented to unless expressly agreed to by the
     Licensor.

  d. Nothing in this Public License constitutes or may be interpreted
     as a limitation upon, or waiver of, any privileges and immunities
     that apply to the Licensor or You, including from the legal
     processes of any jurisdiction or authority.

      designated in writing by the copyright owner as "Not a Contribution."

      "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.

   2. Grant of Copyright License. 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.

   3. Grant of Patent License. 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.

   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.

          "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.

          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions

          subsequently incorporated within the Work.

      2. Grant of Copyright License. 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.

         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

             stating that You changed the files; 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

To the extent this Public License may be interpreted as a contract, You are granted the Licensed Rights in consideration of Your acceptance of these terms and conditions, and the Licensor grants You such rights in consideration of benefits the Licensor receives from making the Licensed Material available under these terms and conditions.

**Section 1 – Definitions.**

1.  **Adapted Material**  means material subject to Copyright and Similar Rights that is derived from or based upon the Licensed Material and in which the Licensed Material is translated, altered, arranged, transformed, or otherwise modified in a manner requiring permission under the Copyright and Similar Rights held by the Licensor. For purposes of this Public License, where the Licensed Material is a musical work, performance, or sound recording, Adapted Material is always produced where the Licensed Material is synched in timed relation with a moving image.
2.  **Adapter's License**  means the license You apply to Your Copyright and Similar Rights in Your contributions to Adapted Material in accordance with the terms and conditions of this Public License.
3.  **BY-SA Compatible License**  means a license listed at  [creativecommons.org/compatiblelicenses](https://creativecommons.org/compatiblelicenses), approved by Creative Commons as essentially the equivalent of this Public License.
4.  **Copyright and Similar Rights**  means copyright and/or similar rights closely related to copyright including, without limitation, performance, broadcast, sound recording, and Sui Generis Database Rights, without regard to how the rights are labeled or categorized. For purposes of this Public License, the rights specified in Section  [2(b)(1)-(2)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s2b)  are not Copyright and Similar Rights.
5.  **Effective Technological Measures**  means those measures that, in the absence of proper authority, may not be circumvented under laws fulfilling obligations under Article 11 of the WIPO Copyright Treaty adopted on December 20, 1996, and/or similar international agreements.
6.  **Exceptions and Limitations**  means fair use, fair dealing, and/or any other exception or limitation to Copyright and Similar Rights that applies to Your use of the Licensed Material.
7.  **License Elements**  means the license attributes listed in the name of a Creative Commons Public License. The License Elements of this Public License are Attribution and ShareAlike.
8.  **Licensed Material**  means the artistic or literary work, database, or other material to which the Licensor applied this Public License.
9.  **Licensed Rights**  means the rights granted to You subject to the terms and conditions of this Public License, which are limited to all Copyright and Similar Rights that apply to Your use of the Licensed Material and that the Licensor has authority to license.

11.  **Share**  means to provide material to the public by any means or process that requires permission under the Licensed Rights, such as reproduction, public display, public performance, distribution, dissemination, communication, or importation, and to make material available to the public including in ways that members of the public may access the material from a place and at a time individually chosen by them.
12.  **Sui Generis Database Rights**  means rights other than copyright resulting from Directive 96/9/EC of the European Parliament and of the Council of 11 March 1996 on the legal protection of databases, as amended and/or succeeded, as well as other essentially equivalent rights anywhere in the world.
13.  **You**  means the individual or entity exercising the Licensed Rights under this Public License.  **Your**  has a corresponding meaning.

**Section 2 – Scope.**

1.  **License grant**.
    1.  Subject to the terms and conditions of this Public License, the Licensor hereby grants You a worldwide, royalty-free, non-sublicensable, non-exclusive, irrevocable license to exercise the Licensed Rights in the Licensed Material to:
        1.  reproduce and Share the Licensed Material, in whole or in part; and
        2.  produce, reproduce, and Share Adapted Material.
    2.  Exceptions and Limitations. For the avoidance of doubt, where Exceptions and Limitations apply to Your use, this Public License does not apply, and You do not need to comply with its terms and conditions.
    3.  Term. The term of this Public License is specified in Section  [6(a)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s6a).
    4.  Media and formats; technical modifications allowed. The Licensor authorizes You to exercise the Licensed Rights in all media and formats whether now known or hereafter created, and to make technical modifications necessary to do so. The Licensor waives and/or agrees not to assert any right or authority to forbid You from making technical modifications necessary to exercise the Licensed Rights, including technical modifications necessary to circumvent Effective Technological Measures. For purposes of this Public License, simply making modifications authorized by this Section  [2(a)(4)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s2a4)  never produces Adapted Material.
    5.  Downstream recipients.

        1.  Offer from the Licensor – Licensed Material. Every recipient of the Licensed Material automatically receives an offer from the Licensor to exercise the Licensed Rights under the terms and conditions of this Public License.
        2.  Additional offer from the Licensor – Adapted Material. Every recipient of Adapted Material from You automatically receives an offer from the Licensor to exercise the Licensed Rights in the Adapted Material under the conditions of the Adapter’s License You apply.
        3.  No downstream restrictions. You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, the Licensed Material if doing so restricts exercise of the Licensed Rights by any recipient of the Licensed Material.

    6.  No endorsement. Nothing in this Public License constitutes or may be construed as permission to assert or imply that You are, or that Your use of the Licensed Material is, connected with, or sponsored, endorsed, or granted official status by, the Licensor or others designated to receive attribution as provided in Section  [3(a)(1)(A)(i)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s3a1Ai).
2.  **Other rights**.

    1.  Moral rights, such as the right of integrity, are not licensed under this Public License, nor are publicity, privacy, and/or other similar personality rights; however, to the extent possible, the Licensor waives and/or agrees not to assert any such rights held by the Licensor to the limited extent necessary to allow You to exercise the Licensed Rights, but not otherwise.
    2.  Patent and trademark rights are not licensed under this Public License.
    3.  To the extent possible, the Licensor waives any right to collect royalties from You for the exercise of the Licensed Rights, whether directly or through a collecting society under any voluntary or waivable statutory or compulsory licensing scheme. In all other cases the Licensor expressly reserves any right to collect such royalties.

**Section 3 – License Conditions.**

Your exercise of the Licensed Rights is expressly made subject to the following conditions.

1.  **Attribution**.

    1.  If You Share the Licensed Material (including in modified form), You must:

        1.  retain the following if it is supplied by the Licensor with the Licensed Material:
            1.  identification of the creator(s) of the Licensed Material and any others designated to receive attribution, in any reasonable manner requested by the Licensor (including by pseudonym if designated);
            2.  a copyright notice;
            3.  a notice that refers to this Public License;
            4.  a notice that refers to the disclaimer of warranties;
            5.  a URI or hyperlink to the Licensed Material to the extent reasonably practicable;
        2.  indicate if You modified the Licensed Material and retain an indication of any previous modifications; and
        3.  indicate the Licensed Material is licensed under this Public License, and include the text of, or the URI or hyperlink to, this Public License.
    2.  You may satisfy the conditions in Section  [3(a)(1)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s3a1)  in any reasonable manner based on the medium, means, and context in which You Share the Licensed Material. For example, it may be reasonable to satisfy the conditions by providing a URI or hyperlink to a resource that includes the required information.
    3.  If requested by the Licensor, You must remove any of the information required by Section  [3(a)(1)(A)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s3a1A)  to the extent reasonably practicable.
2.  **ShareAlike**.

    In addition to the conditions in Section  [3(a)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s3a), if You Share Adapted Material You produce, the following conditions also apply.

    1.  The Adapter’s License You apply must be a Creative Commons license with the same License Elements, this version or later, or a BY-SA Compatible License.
    2.  You must include the text of, or the URI or hyperlink to, the Adapter's License You apply. You may satisfy this condition in any reasonable manner based on the medium, means, and context in which You Share Adapted Material.
    3.  You may not offer or impose any additional or different terms or conditions on, or apply any Effective Technological Measures to, Adapted Material that restrict exercise of the rights granted under the Adapter's License You apply.

**Section 4 – Sui Generis Database Rights.**

Where the Licensed Rights include Sui Generis Database Rights that apply to Your use of the Licensed Material:

1.  for the avoidance of doubt, Section  [2(a)(1)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s2a1)  grants You the right to extract, reuse, reproduce, and Share all or a substantial portion of the contents of the database;
2.  if You include all or a substantial portion of the database contents in a database in which You have Sui Generis Database Rights, then the database in which You have Sui Generis Database Rights (but not its individual contents) is Adapted Material, including for purposes of Section  [3(b)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s3b); and
3.  You must comply with the conditions in Section  [3(a)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s3a)  if You Share all or a substantial portion of the contents of the database.

For the avoidance of doubt, this Section [4](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s4) supplements and does not replace Your obligations under this Public License where the Licensed Rights include other Copyright and Similar Rights.

**Section 5 – Disclaimer of Warranties and Limitation of Liability.**

1.  **Unless otherwise separately undertaken by the Licensor, to the extent possible, the Licensor offers the Licensed Material as-is and as-available, and makes no representations or warranties of any kind concerning the Licensed Material, whether express, implied, statutory, or other. This includes, without limitation, warranties of title, merchantability, fitness for a particular purpose, non-infringement, absence of latent or other defects, accuracy, or the presence or absence of errors, whether or not known or discoverable. Where disclaimers of warranties are not allowed in full or in part, this disclaimer may not apply to You.**
2.  **To the extent possible, in no event will the Licensor be liable to You on any legal theory (including, without limitation, negligence) or otherwise for any direct, special, indirect, incidental, consequential, punitive, exemplary, or other losses, costs, expenses, or damages arising out of this Public License or use of the Licensed Material, even if the Licensor has been advised of the possibility of such losses, costs, expenses, or damages. Where a limitation of liability is not allowed in full or in part, this limitation may not apply to You.**

3.  The disclaimer of warranties and limitation of liability provided above shall be interpreted in a manner that, to the extent possible, most closely approximates an absolute disclaimer and waiver of all liability.

**Section 6 – Term and Termination.**

1.  This Public License applies for the term of the Copyright and Similar Rights licensed here. However, if You fail to comply with this Public License, then Your rights under this Public License terminate automatically.
2.  Where Your right to use the Licensed Material has terminated under Section  [6(a)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s6a), it reinstates:

    1.  automatically as of the date the violation is cured, provided it is cured within 30 days of Your discovery of the violation; or
    2.  upon express reinstatement by the Licensor.

    For the avoidance of doubt, this Section  [6(b)](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s6b)  does not affect any right the Licensor may have to seek remedies for Your violations of this Public License.
3.  For the avoidance of doubt, the Licensor may also offer the Licensed Material under separate terms or conditions or stop distributing the Licensed Material at any time; however, doing so will not terminate this Public License.
4.  Sections  [1](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s1),  [5](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s5),  [6](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s6),  [7](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s7), and  [8](https://creativecommons.org/licenses/by-sa/4.0/legalcode#s8)  survive termination of this Public License.

**Section 7 – Other Terms and Conditions.**

1.  The Licensor shall not be bound by any additional or different terms or conditions communicated by You unless expressly agreed.
2.  Any arrangements, understandings, or agreements regarding the Licensed Material not stated herein are separate from and independent of the terms and conditions of this Public License.

**Section 8 – Interpretation.**

1.  For the avoidance of doubt, this Public License does not, and shall not be interpreted to, reduce, limit, restrict, or impose conditions on any use of the Licensed Material that could lawfully be made without permission under this Public License.
2.  To the extent possible, if any provision of this Public License is deemed unenforceable, it shall be automatically reformed to the minimum extent necessary to make it enforceable. If the provision cannot be reformed, it shall be severed from this Public License without affecting the enforceability of the remaining terms and conditions.
3.  No term or condition of this Public License will be waived and no failure to comply consented to unless expressly agreed to by the Licensor.
4.  Nothing in this Public License constitutes or may be interpreted as a limitation upon, or waiver of, any privileges and immunities that apply to the Licensor or You, including from the legal processes of any jurisdiction or authority.

          "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.

          "Contribution" shall mean any work of authorship, including
          the original version of the Work and any modifications or additions

          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

          "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.

      2. Grant of Copyright License. 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.

      3. Grant of Patent License. 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.

      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,

      "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.

      "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).

      "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.

      "Contribution" shall mean any work of authorship, including

      the copyright owner. For the purposes of this definition, "submitted"
      means any form of electronic, verbal, or written communication sent

      designated in writing by the copyright owner as "Not a Contribution."

      "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.

   2. Grant of Copyright License. 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.

   3. Grant of Patent License. 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.

   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.

      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.

      and conversions to other media types.

      "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).

      "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.

      "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.

      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.

   3. Grant of Patent License. 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,

      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

      (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

          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

      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.

      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.

                   GNU LESSER GENERAL PUBLIC LICENSE
                       Version 3, 29 June 2007

 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
 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.

         publicly display, publicly perform, sublicense, and distribute the
         Work and such Derivative Works in Source or Object form.

      3. Grant of Patent License. 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.

      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.
