-Written in 2016 by Aras Ergus <arasergus@posteo.net>
-
----
-
-To the extent possible under law, the author(s) have dedicated all copyright
-and related and neighboring rights to this software to the public domain
-worldwide by associating CC0 with it. This software is distributed without
-any warranty.
-
----
-
-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.
