+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
+
+1. "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.
+2. "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.
+3. "Creative Commons Compatible License" means a license that is listed
+ at http://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.
+4. "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.
+5. "License Elements" means the following high-level license attributes

+ Attribution, ShareAlike.
+6. "Licensor" means the individual, individuals, entity or entities
+ that offer(s) the Work under the terms of this License.
+7. "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.
+8. "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.
+9. "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.
+10. "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.
+11. "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:
+
+1. to Reproduce the Work, to incorporate the Work into one or more
+ Collections, and to Reproduce the Work as incorporated in the
+ Collections;
+2. 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.";
+3. to Distribute and Publicly Perform the Work including as
+ incorporated in Collections; and,
+4. to Distribute and Publicly Perform Adaptations.
+5. For the avoidance of doubt:
+
+ 1. 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;
+ 2. 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,
+ 3. 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:
+
+1. 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.
+2. 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.
+3. 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.
+4. 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
+
+1. 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.
+2. 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
+
+1. 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.
+2. 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.
+3. 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.
+4. 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.
+5. 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.
+6. 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.
+
+ Creative Commons Notice
+
+ Creative Commons is not a party to this License, and makes no warranty
+ whatsoever in connection with the Work. Creative Commons will not be
+ liable to You or any party on any legal theory for any damages
+ whatsoever, including without limitation any general, special,
+ incidental or consequential damages arising in connection to this
+ license. Notwithstanding the foregoing two (2) sentences, if Creative
+ Commons has expressly identified itself as the Licensor hereunder, it
+ shall have all rights and obligations of Licensor.
+
+ Except for the limited purpose of indicating to the public that the
+ Work is licensed under the CCPL, Creative Commons does not authorize
+ the use by either party of the trademark "Creative Commons" or any
+ related trademark or logo of Creative Commons without the prior
+ written consent of Creative Commons. Any permitted use will be in
+ compliance with Creative Commons' then-current trademark usage
+ guidelines, as may be published on its website or otherwise made
+ available upon request from time to time. For the avoidance of doubt,
+ this trademark restriction does not form part of the License.
