+Creative Commons Legal Code
+
+CC0 1.0 Universal
+
+    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
+    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
+    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
+    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
+    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
+    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
+    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
+    HEREUNDER.
+
+Statement of Purpose
+
+The laws of most jurisdictions throughout the world automatically confer
+exclusive Copyright and Related Rights (defined below) upon the creator
+and subsequent owner(s) (each and all, an "owner") of an original work of
+authorship and/or a database (each, a "Work").
+
+Certain owners wish to permanently relinquish those rights to a Work for
+the purpose of contributing to a commons of creative, cultural and
+scientific works ("Commons") that the public can reliably and without fear
+of later claims of infringement build upon, modify, incorporate in other
+works, reuse and redistribute as freely as possible in any form whatsoever
+and for any purposes, including without limitation commercial purposes.
+These owners may contribute to the Commons to promote the ideal of a free
+culture and the further production of creative, cultural and scientific
+works, or to gain reputation or greater distribution for their Work in
+part through the use and efforts of others.
+
+For these and/or other purposes and motivations, and without any
+expectation of additional consideration or compensation, the person
+associating CC0 with a Work (the "Affirmer"), to the extent that he or she
+is an owner of Copyright and Related Rights in the Work, voluntarily
+elects to apply CC0 to the Work and publicly distribute the Work under its
+terms, with knowledge of his or her Copyright and Related Rights in the
+Work and the meaning and intended legal effect of CC0 on those rights.
+
+1. Copyright and Related Rights. A Work made available under CC0 may be
+   protected by copyright and related or neighboring rights ("Copyright and
+   Related Rights"). Copyright and Related Rights include, but are not
+   limited to, the following:
+
+i. the right to reproduce, adapt, distribute, perform, display,
+communicate, and translate a Work;
+ii. moral rights retained by the original author(s) and/or performer(s);
+iii. publicity and privacy rights pertaining to a person's image or
+likeness depicted in a Work;
+iv. rights protecting against unfair competition in regards to a Work,
+subject to the limitations in paragraph 4(a), below;
+v. rights protecting the extraction, dissemination, use and reuse of data
+in a Work;
+vi. database rights (such as those arising under Directive 96/9/EC of the
+European Parliament and of the Council of 11 March 1996 on the legal
+protection of databases, and under any national implementation
+thereof, including any amended or successor version of such
+directive); and
+vii. other similar, equivalent or corresponding rights throughout the
+world based on applicable law or treaty, and any national
+implementations thereof.
+
+2. Waiver. To the greatest extent permitted by, but not in contravention
+   of, applicable law, Affirmer hereby overtly, fully, permanently,
+   irrevocably and unconditionally waives, abandons, and surrenders all of
+   Affirmer's Copyright and Related Rights and associated claims and causes
+   of action, whether now known or unknown (including existing as well as
+   future claims and causes of action), in the Work (i) in all territories
+   worldwide, (ii) for the maximum duration provided by applicable law or
+   treaty (including future time extensions), (iii) in any current or future
+   medium and for any number of copies, and (iv) for any purpose whatsoever,
+   including without limitation commercial, advertising or promotional
+   purposes (the "Waiver"). Affirmer makes the Waiver for the benefit of each
+   member of the public at large and to the detriment of Affirmer's heirs and
+   successors, fully intending that such Waiver shall not be subject to
+   revocation, rescission, cancellation, termination, or any other legal or
+   equitable action to disrupt the quiet enjoyment of the Work by the public
+   as contemplated by Affirmer's express Statement of Purpose.
+
+3. Public License Fallback. Should any part of the Waiver for any reason
+   be judged legally invalid or ineffective under applicable law, then the
+   Waiver shall be preserved to the maximum extent permitted taking into
+   account Affirmer's express Statement of Purpose. In addition, to the
+   extent the Waiver is so judged Affirmer hereby grants to each affected
+   person a royalty-free, non transferable, non sublicensable, non exclusive,
+   irrevocable and unconditional license to exercise Affirmer's Copyright and
+   Related Rights in the Work (i) in all territories worldwide, (ii) for the
+   maximum duration provided by applicable law or treaty (including future
+   time extensions), (iii) in any current or future medium and for any number
+   of copies, and (iv) for any purpose whatsoever, including without
+   limitation commercial, advertising or promotional purposes (the
+   "License"). The License shall be deemed effective as of the date CC0 was
+   applied by Affirmer to the Work. Should any part of the License for any
+   reason be judged legally invalid or ineffective under applicable law, such
+   partial invalidity or ineffectiveness shall not invalidate the remainder
+   of the License, and in such case Affirmer hereby affirms that he or she
+   will not (i) exercise any of his or her remaining Copyright and Related
+   Rights in the Work or (ii) assert any associated claims and causes of
+   action with respect to the Work, in either case contrary to Affirmer's
+   express Statement of Purpose.
+
+4. Limitations and Disclaimers.
+
+a. No trademark or patent rights held by Affirmer are waived, abandoned,
+surrendered, licensed or otherwise affected by this document.
+b. Affirmer 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, merchantability, fitness for a particular purpose, non
+infringement, or the absence of latent or other defects, accuracy, or
+the present or absence of errors, whether or not discoverable, all to
+the greatest extent permissible under applicable law.
+c. Affirmer disclaims responsibility for clearing rights of other persons
+that may apply to the Work or any use thereof, including without
+limitation any person's Copyright and Related Rights in the Work.
+Further, Affirmer disclaims responsibility for obtaining any necessary
+consents, permissions or other rights required for any use of the
+Work.
+d. Affirmer understands and acknowledges that Creative Commons is not a
+party to this document and has no duty or obligation with respect to
+this CC0 or use of the Work.
