License

THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS
CREATIVE COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS
PROTECTED BY COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK
OTHER THAN AS AUTHORIZED UNDER THIS LICENSE OR COPYRIGHT LAW IS
PROHIBITED.

BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND
AGREE TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS
LICENSE MAY BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE
RIGHTS CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS
AND CONDITIONS.

1. Definitions

    a. "Adaptation" means a work based upon the Work, or upon the Work
    and other pre-existing works, such as a translation, adaptation,
    derivative work, arrangement of music or other alterations of a
    literary or artistic work, or phonogram or performance and includes
    cinematographic adaptations or any other form in which the Work may
    be recast, transformed, or adapted including in any form
    recognizably derived from the original, except that a work that
    constitutes a Collection will not be considered an Adaptation for
    the purpose of this License. For the avoidance of doubt, where the
    Work is a musical work, performance or phonogram, the
    synchronization of the Work in timed-relation with a moving image
    ("synching") will be considered an Adaptation for the purpose of
    this License.
    
    b. "Collection" means a collection of literary or artistic works
    such as encyclopedias and anthologies, or performances, phonograms
    or broadcasts, or other works or subject matter other than works
    listed in Section 1(f) below, which, by reason of the selection and
    arrangement of their contents, constitute intellectual creations,
    in which the Work is included in its entirety in unmodified form
    along with one or more other contributions, each constituting
    separate and independent works in themselves, which together are
    assembled into a collective whole. A work that constitutes a
    Collection will not be considered an Adaptation (as defined below)
    for the purposes of this License.

    c. "Creative Commons Compatible License" means a license that is
    listed at https://creativecommons.org/compatiblelicenses that has
    been approved by Creative Commons as being essentially equivalent
    to this License, including, at a minimum, because that license: (i)
    contains terms that have the same purpose, meaning and effect as
    the License Elements of this License; and, (ii) explicitly permits
    the relicensing of adaptations of works made available under that
    license under this License or a Creative Commons jurisdiction
    license with the same License Elements as this License.

    d. "Distribute" means to make available to the public the original
    and copies of the Work or Adaptation, as appropriate, through sale
    or other transfer of ownership.

    attributes as selected by Licensor and indicated in the title of
    this License: Attribution, ShareAlike.
    
    f. "Licensor" means the individual, individuals, entity or entities
    that offer(s) the Work under the terms of this License.

    g. "Original Author" means, in the case of a literary or artistic

    the Work or if no individual or entity can be identified, the
    publisher; and in addition (i) in the case of a performance the
    actors, singers, musicians, dancers, and other persons who act,
    sing, deliver, declaim, play in, interpret or otherwise perform
    literary or artistic works or expressions of folklore; (ii) in the
    case of a phonogram the producer being the person or legal entity
    who first fixes the sounds of a performance or other sounds; and,
    (iii) in the case of broadcasts, the organization that transmits
    the broadcast.

    h. "Work" means the literary and/or artistic work offered under the
    terms of this License including without limitation any production
    in the literary, scientific and artistic domain, whatever may be
    the mode or form of its expression including digital form, such as
    a book, pamphlet and other writing; a lecture, address, sermon or
    other work of the same nature; a dramatic or dramatico-musical
    work; a choreographic work or entertainment in dumb show; a musical
    composition with or without words; a cinematographic work to which
    are assimilated works expressed by a process analogous to
    cinematography; a work of drawing, painting, architecture,
    sculpture, engraving or lithography; a photographic work to which
    are assimilated works expressed by a process analogous to
    photography; a work of applied art; an illustration, map, plan,
    sketch or three-dimensional work relative to geography, topography,
    architecture or science; a performance; a broadcast; a phonogram; a
    compilation of data to the extent it is protected as a
    copyrightable work; or a work performed by a variety or circus
    performer to the extent it is not otherwise considered a literary
    or artistic work.

    i. "You" means an individual or entity exercising rights under this
    License who has not previously violated the terms of this License
    with respect to the Work, or who has received express permission
    from the Licensor to exercise rights under this License despite a
    previous violation.

    j. "Publicly Perform" means to perform public recitations of the
    Work and to communicate to the public those public recitations, by
    any means or process, including by wire or wireless means or public
    digital performances; to make available to the public Works in such
    a way that members of the public may access these Works from a
    place and at a place individually chosen by them; to perform the
    Work to the public by any means or process and the communication to

    right of fixation and reproducing fixations of the Work, including
    storage of a protected performance or phonogram in digital form or
    other electronic medium.

2. Fair Dealing Rights. Nothing in this License is intended to reduce,
limit, or restrict any uses free from copyright or rights arising from
limitations or exceptions that are provided for in connection with the
copyright protection under copyright law or other applicable laws.

3. License Grant. Subject to the terms and conditions of this License,
Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
perpetual (for the duration of the applicable copyright) license to
exercise the rights in the Work as stated below:

    a. to Reproduce the Work, to incorporate the Work into one or more
    Collections, and to Reproduce the Work as incorporated in the
    Collections;
    
    b. to create and Reproduce Adaptations provided that any such
    Adaptation, including any translation in any medium, takes
    reasonable steps to clearly label, demarcate or otherwise identify
    that changes were made to the original Work. For example, a
    translation could be marked "The original work was translated from
    English to Spanish," or a modification could indicate "The original
    work has been modified.";
    
    c. to Distribute and Publicly Perform the Work including as
    incorporated in Collections; and,
    
    d. to Distribute and Publicly Perform Adaptations.

    e. For the avoidance of doubt:
        i. Non-waivable Compulsory License Schemes. In those
        jurisdictions in which the right to collect royalties through
        any statutory or compulsory licensing scheme cannot be waived,
        the Licensor reserves the exclusive right to collect such
        royalties for any exercise by You of the rights granted under
        this License;

        ii. Waivable Compulsory License Schemes. In those jurisdictions
        in which the right to collect royalties through any statutory
        or compulsory licensing scheme can be waived, the Licensor
        waives the exclusive right to collect such royalties for any
        exercise by You of the rights granted under this License; and,

        iii. Voluntary License Schemes. The Licensor waives the right
        to collect royalties, whether individually or, in the event
        that the Licensor is a member of a collecting society that
        administers voluntary licensing schemes, via that society, from
        any exercise by You of the rights granted under this License.

The above rights may be exercised in all media and formats whether now
known or hereafter devised. The above rights include the right to make
such modifications as are technically necessary to exercise the rights
in other media and formats. Subject to Section 8(f), all rights not
expressly granted by Licensor are hereby reserved.

4. Restrictions. The license granted in Section 3 above is expressly
made subject to and limited by the following restrictions:

    a. You may Distribute or Publicly Perform the Work only under the
    terms of this License. You must include a copy of, or the Uniform
    Resource Identifier (URI) for, this License with every copy of the
    Work You Distribute or Publicly Perform. You may not offer or
    impose any terms on the Work that restrict the terms of this
    License or the ability of the recipient of the Work to exercise the
    rights granted to that recipient under the terms of the License.
    You may not sublicense the Work. You must keep intact all notices
    that refer to this License and to the disclaimer of warranties with
    every copy of the Work You Distribute or Publicly Perform. When You
    Distribute or Publicly Perform the Work, You may not impose any
    effective technological measures on the Work that restrict the
    ability of a recipient of the Work from You to exercise the rights
    granted to that recipient under the terms of the License. This
    Section 4(a) applies to the Work as incorporated in a Collection,
    but this does not require the Collection apart from the Work itself
    to be made subject to the terms of this License. If You create a
    Collection, upon notice from any Licensor You must, to the extent
    practicable, remove from the Collection any credit as required by
    Section 4(c), as requested. If You create an Adaptation, upon
    notice from any Licensor You must, to the extent practicable,
    remove from the Adaptation any credit as required by Section 4(c),
    as requested.

    b. You may Distribute or Publicly Perform an Adaptation only under
    the terms of: (i) this License; (ii) a later version of this
    License with the same License Elements as this License; (iii) a
    Creative Commons jurisdiction license (either this or a later
    license version) that contains the same License Elements as this
    License (e.g., Attribution-ShareAlike 3.0 US)); (iv) a Creative
    Commons Compatible License. If you license the Adaptation under one
    of the licenses mentioned in (iv), you must comply with the terms
    of that license. If you license the Adaptation under the terms of
    any of the licenses mentioned in (i), (ii) or (iii) (the
    "Applicable License"), you must comply with the terms of the
    Applicable License generally and the following provisions: (I) You
    must include a copy of, or the URI for, the Applicable License with
    every copy of each Adaptation You Distribute or Publicly Perform;
    (II) You may not offer or impose any terms on the Adaptation that
    restrict the terms of the Applicable License or the ability of the
    recipient of the Adaptation to exercise the rights granted to that
    recipient under the terms of the Applicable License; (III) You must
    keep intact all notices that refer to the Applicable License and to
    the disclaimer of warranties with every copy of the Work as
    included in the Adaptation You Distribute or Publicly Perform; (IV)
    when You Distribute or Publicly Perform the Adaptation, You may not
    impose any effective technological measures on the Adaptation that
    restrict the ability of a recipient of the Adaptation from You to
    exercise the rights granted to that recipient under the terms of
    the Applicable License. This Section 4(b) applies to the Adaptation
    as incorporated in a Collection, but this does not require the
    Collection apart from the Adaptation itself to be made subject to
    the terms of the Applicable License.

    c. If You Distribute, or Publicly Perform the Work or any
    Adaptations or Collections, You must, unless a request has been
    made pursuant to Section 4(a), keep intact all copyright notices
    for the Work and provide, reasonable to the medium or means You are
    utilizing: (i) the name of the Original Author (or pseudonym, if
    applicable) if supplied, and/or if the Original Author and/or
    Licensor designate another party or parties (e.g., a sponsor
    institute, publishing entity, journal) for attribution
    ("Attribution Parties") in Licensor's copyright notice, terms of
    service or by other reasonable means, the name of such party or
    parties; (ii) the title of the Work if supplied; (iii) to the
    extent reasonably practicable, the URI, if any, that Licensor
    specifies to be associated with the Work, unless such URI does not
    refer to the copyright notice or licensing information for the
    Work; and (iv) , consistent with Ssection 3(b), in the case of an
    Adaptation, a credit identifying the use of the Work in the
    Adaptation (e.g., "French translation of the Work by Original
    Author," or "Screenplay based on original Work by Original
    Author"). The credit required by this Section 4(c) may be
    implemented in any reasonable manner; provided, however, that in
    the case of a Adaptation or Collection, at a minimum such credit
    will appear, if a credit for all contributing authors of the
    Adaptation or Collection appears, then as part of these credits and
    in a manner at least as prominent as the credits for the other
    contributing authors. For the avoidance of doubt, You may only use
    the credit required by this Section for the purpose of attribution
    in the manner set out above and, by exercising Your rights under
    this License, You may not implicitly or explicitly assert or imply
    any connection with, sponsorship or endorsement by the Original
    Author, Licensor and/or Attribution Parties, as appropriate, of You
    or Your use of the Work, without the separate, express prior
    written permission of the Original Author, Licensor and/or
    Attribution Parties.

    d. Except as otherwise agreed in writing by the Licensor or as may
    be otherwise permitted by applicable law, if You Reproduce,
    Distribute or Publicly Perform the Work either by itself or as part
    of any Adaptations or Collections, You must not distort, mutilate,
    modify or take other derogatory action in relation to the Work
    which would be prejudicial to the Original Author's honor or
    reputation. Licensor agrees that in those jurisdictions (e.g.
    Japan), in which any exercise of the right granted in Section 3(b)
    of this License (the right to make Adaptations) would be deemed to
    be a distortion, mutilation, modification or other derogatory
    action prejudicial to the Original Author's honor and reputation,
    the Licensor will waive or not assert, as appropriate, this
    Section, to the fullest extent permitted by the applicable national
    law, to enable You to reasonably exercise Your right under Section 
    (b) of this License (right to make Adaptations) but not otherwise.

5. Representations, Warranties and Disclaimer

UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
OFFERS THE WORK AS-IS AND MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY
KIND CONCERNING THE WORK, EXPRESS, IMPLIED, STATUTORY OR OTHERWISE,
INCLUDING, WITHOUT LIMITATION, WARRANTIES OF TITLE, MERCHANTIBILITY,
FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF
ERRORS, WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW
THE EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO
YOU.

6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR
HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

7. Termination

    a. This License and the rights granted hereunder will terminate
    automatically upon any breach by You of the terms of this License.
    Individuals or entities who have received Adaptations or
    Collections from You under this License, however, will not have
    their licenses terminated provided such individuals or entities
    remain in full compliance with those licenses. Sections 1, 2, 5, 6,
    7, and 8 will survive any termination of this License.

    b. Subject to the above terms and conditions, the license granted
    here is perpetual (for the duration of the applicable copyright in
    the Work). Notwithstanding the above, Licensor reserves the right
    to release the Work under different license terms or to stop
    distributing the Work at any time; provided, however that any such
    election will not serve to withdraw this License (or any other
    license that has been, or is required to be, granted under the
    terms of this License), and this License will continue in full
    force and effect unless terminated as stated above.

8. Miscellaneous

    a. Each time You Distribute or Publicly Perform the Work or a
    Collection, the Licensor offers to the recipient a license to the
    Work on the same terms and conditions as the license granted to You
    under this License.

    b. Each time You Distribute or Publicly Perform an Adaptation,
    Licensor offers to the recipient a license to the original Work on
    the same terms and conditions as the license granted to You under
    this License.

    c. If any provision of this License is invalid or unenforceable
    under applicable law, it shall not affect the validity or
    enforceability of the remainder of the terms of this License, and
    without further action by the parties to this agreement, such
    provision shall be reformed to the minimum extent necessary to make
    such provision valid and enforceable.

    d. No term or provision of this License shall be deemed waived and
    no breach consented to unless such waiver or consent shall be in
    writing and signed by the party to be charged with such waiver or
    consent.

    e. This License constitutes the entire agreement between the
    parties with respect to the Work licensed here. There are no
    understandings, agreements or representations with respect to the
    Work not specified here. Licensor shall not be bound by any
    additional provisions that may appear in any communication from
    You. This License may not be modified without the mutual written
    agreement of the Licensor and You.

    f. The rights granted under, and the subject matter referenced, in
    this License were drafted utilizing the terminology of the Berne
    Convention for the Protection of Literary and Artistic Works (as
    amended on September 28, 1979), the Rome Convention of 1961, the
    WIPO Copyright Treaty of 1996, the WIPO Performances and Phonograms
    Treaty of 1996 and the Universal Copyright Convention (as revised
    on July 24, 1971). These rights and subject matter take effect in
    the relevant jurisdiction in which the License terms are sought to
    be enforced according to the corresponding provisions of the
    implementation of those treaty provisions in the applicable
    national law. If the standard suite of rights granted under
    applicable copyright law includes additional rights not granted
    under this License, such additional rights are deemed to be
    included in the License; this License is not intended to restrict
    the license of any rights under applicable law.
