  DEALINGS IN THE SOFTWARE.
 
+License: CC0-1.0
+ CC0 1.0 Universal
+ .
+ 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.
