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.
