-Statement of Purpose 
- 
-The laws of most jurisdictions throughout the world automatically confer

-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.

-    this CC0 or use of the Work.
