+    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

+
+    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.

+
+    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.

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

+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

+    always produced where the Licensed Material is synched in timed
+    relation with a moving image.

+    accordance with the terms and conditions of this Public License.

+    closely related to copyright including, without limitation,

+    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

+ 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. "Share" means to provide material to the public by any means or
+    process that requires permission under the Licensed Rights, such as

+    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.
