 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.
