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.
