    Attribution-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

    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.

     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

  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. 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.

  l. 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.

  m. 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;
               and

            b. 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).

       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.

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-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;

  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.
