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.

                 national implementation thereof, including any amended or successor version of such
                 directive); and

                 law or treaty, and any national implementations thereof.
        

          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.

          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.
