CC0 1.0 Universal - https://creativecommons.org/publicdomain/zero/1.0/legalcode

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.
