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 above) for the purposes of this License.

    c. "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.

    d. "Licensor" means the individual, individuals, entity or entities that
       offer(s) the Work under the terms of this License.

    e. "Original Author" means, in the case of a literary or artistic work, the
       individual, individuals, entity or entities who created 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.

    f. "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.

    g. "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.

    h. "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 the public of the performances
       of the Work, including by public digital performance; to broadcast and
       rebroadcast the Work by any means including signs, sounds or images.

    i. "Reproduce" means to make copies of the Work by any means including
       without limitation by sound or visual recordings and the 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(b), 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(b), as requested.

    b. 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 Section 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 (b) 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.

    c. 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 3(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.
