+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.
