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:

      the right to reproduce, adapt, distribute, perform, display,
      communicate, and translate a Work;

      moral rights retained by the original author(s) and/or
      performer(s);

      publicity and privacy rights pertaining to a person's image or
      likeness depicted in a Work;

      rights protecting against unfair competition in regards to a
      Work, subject to the limitations in paragraph 4(a), below;

      rights protecting the extraction, dissemination, use and reuse
      of data in a Work;

      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

      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.

   No trademark or patent rights held by Affirmer are waived,
   abandoned, surrendered, licensed or otherwise affected by this
   document.

   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.

   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.

   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.
