+CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE LEGAL
+SERVICES. DISTRIBUTION OF THIS LICENSE DOES NOT CREATE AN ATTORNEY-CLIENT
+RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS INFORMATION ON AN "AS-IS" BASIS.
+CREATIVE COMMONS MAKES NO WARRANTIES REGARDING THE INFORMATION PROVIDED, AND

+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. THE LICENSOR GRANTS YOU THE RIGHTS
+CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
+CONDITIONS.
+1. Definitions
+
+  a. "Collective Work" means a work, such as a periodical issue, anthology or
+     encyclopedia, in which the Work in its entirety in unmodified form, along
+     with a number of other contributions, constituting separate and
+     independent works in themselves, are assembled into a collective whole. A
+     work that constitutes a Collective Work will not be considered a
+     Derivative Work (as defined below) for the purposes of this License.
+  b. "Derivative Work" means a work based upon the Work or upon the Work and
+     other pre-existing works, such as a translation, musical arrangement,
+     dramatization, fictionalization, motion picture version, sound recording,
+     art reproduction, abridgment, condensation, or any other form in which the
+     Work may be recast, transformed, or adapted, except that a work that
+     constitutes a Collective Work will not be considered a Derivative Work for
+     the purpose of this License. For the avoidance of doubt, where the Work is
+     a musical composition or sound recording, the synchronization of the Work
+     in timed-relation with a moving image ("synching") will be considered a
+     Derivative Work for the purpose of this License.
+  c. "Licensor" means the individual or entity that offers the Work under the
+     terms of this License.
+  d. "Original Author" means the individual or entity who created the Work.
+  e. "Work" means the copyrightable work of authorship offered under the terms
+     of this License.
+  f. "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.
+  g. "License Elements" means the following high-level license attributes as
+     selected by Licensor and indicated in the title of this License:
+     Attribution, ShareAlike.
+
+2. Fair Use Rights. Nothing in this license is intended to reduce, limit, or
+restrict any rights arising from fair use, first sale or other limitations on
+the exclusive rights of the copyright owner 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 Collective
+     Works, and to reproduce the Work as incorporated in the Collective Works;
+  b. to create and reproduce Derivative Works;
+  c. to distribute copies or phonorecords of, display publicly, perform
+     publicly, and perform publicly by means of a digital audio transmission
+     the Work including as incorporated in Collective Works;
+  d. to distribute copies or phonorecords of, display publicly, perform
+     publicly, and perform publicly by means of a digital audio transmission
+     Derivative Works.
+  e. For the avoidance of doubt, where the work is a musical composition:
+
+       i. Performance Royalties Under Blanket Licenses. Licensor waives the
+          exclusive right to collect, whether individually or via a performance
+          rights society (e.g. ASCAP, BMI, SESAC), royalties for the public
+          performance or public digital performance (e.g. webcast) of the Work.
+      ii. Mechanical Rights and Statutory Royalties. Licensor waives the
+          exclusive right to collect, whether individually or via a music
+          rights society or designated agent (e.g. Harry Fox Agency), royalties
+          for any phonorecord You create from the Work ("cover version") and
+          distribute, subject to the compulsory license created by 17 USC
+          Section 115 of the US Copyright Act (or the equivalent in other
+          jurisdictions).
+
+  f. Webcasting Rights and Statutory Royalties. For the avoidance of doubt,
+     where the Work is a sound recording, Licensor waives the exclusive right
+     to collect, whether individually or via a performance-rights society (e.g.
+     SoundExchange), royalties for the public digital performance (e.g.
+     webcast) of the Work, subject to the compulsory license created by 17 USC
+     Section 114 of the US Copyright Act (or the equivalent in other
+     jurisdictions).
+
+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. 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, publicly display, publicly perform, or publicly
+     digitally perform the Work only under the terms of this License, and You
+     must include a copy of, or the Uniform Resource Identifier for, this
+     License with every copy or phonorecord of the Work You distribute,
+     publicly display, publicly perform, or publicly digitally perform. You may
+     not offer or impose any terms on the Work that alter or restrict the terms
+     of this License or the recipients' exercise of the rights granted
+     hereunder. You may not sublicense the Work. You must keep intact all
+     notices that refer to this License and to the disclaimer of warranties.
+     You may not distribute, publicly display, publicly perform, or publicly
+     digitally perform the Work with any technological measures that control
+     access or use of the Work in a manner inconsistent with the terms of this
+     License Agreement. The above applies to the Work as incorporated in a
+     Collective Work, but this does not require the Collective Work apart from
+     the Work itself to be made subject to the terms of this License. If You
+     create a Collective Work, upon notice from any Licensor You must, to the
+     extent practicable, remove from the Collective Work any credit as required
+     by clause 4(c), as requested. If You create a Derivative Work, upon notice
+     from any Licensor You must, to the extent practicable, remove from the
+     Derivative Work any credit as required by clause 4(c), as requested.
+  b. You may distribute, publicly display, publicly perform, or publicly
+     digitally perform a Derivative Work only under the terms of this License,
+     a later version of this License with the same License Elements as this
+     License, or a Creative Commons iCommons license that contains the same
