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.

     i. No trademark or patent rights held by Affirmer are waived,
        abandoned, surrendered, licensed or otherwise affected by this
        document.
    ii. Affirmer offers the Work as-is and makes no representations or
        warranties of any kind concerning the Work, express, implied,

        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.
   iii. 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.
    iv. 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.
