COPYING

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.
