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
contract, You are granted the Licensed Rights in consideration of Your

such rights in consideration of benefits the Licensor receives from
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

 e. Effective Technological Measures means those measures that, in the
    absence of proper authority, may not be circumvented under laws

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

    equivalent rights anywhere in the world.

    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.
