CC0 1.0 Universal

  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.
