Distribution of\nCreative Commons public licenses does not create a lawyer-client or\nother relationship. Creative Commons makes its licenses and related\ninformation available on an \"as-is\" basis. Creative Commons gives no\nwarranties regarding its licenses, any material licensed under their\nterms and conditions, or any related information. Creative Commons\ndisclaims all liability for damages resulting from their use to the\nfullest extent possible.\nUsing Creative Commons Public Licenses\nCreative Commons public licenses provide a standard set of terms and\nconditions that creators and other rights holders may use to share\noriginal works of authorship and other material subject to copyright\nand certain other rights specified in the public license below. The\nfollowing considerations are for informational purposes only, are\nnot exhaustive, and do not form part of our licenses.\nConsiderations for licensors\nOur public licenses are intended for use by those authorized to give\nthe public permission to use material in ways otherwise restricted\nby copyright and certain other rights. Our licenses are irrevocable.\nLicensors should read and understand the terms and conditions of the\nlicense they choose before applying it. Licensors should also secure\nall rights necessary before applying our licenses so that the public\ncan reuse the material as expected. Licensors should clearly mark\nany material not subject to the license. This includes other\nCC-licensed material, or material used under an exception or\nlimitation to copyright.\nMore considerations for licensors.\nConsiderations for the public\nBy using one of our public licenses, a licensor grants the public\npermission to use the licensed material under specified terms and\nconditions. If the licensor’s permission is not necessary for any\nreason–for example, because of any applicable exception or\nlimitation to copyright–then that use is not regulated by the\nlicense. Our licenses grant only permissions under copyright and\ncertain other rights that a licensor has authority to grant. Use of\nthe licensed material may still be restricted for other reasons,\nincluding because others have copyright or other rights in the\nmaterial. A licensor may make special requests, such as asking that\nall changes be marked or described. Although not required by our\nlicenses, you are encouraged to respect those requests where\nreasonable.\nMore considerations for the public.\nCC0 1.0 Universal\nCREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE\nLEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN\nATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS\nINFORMATION ON AN \"AS-IS\" BASIS. CREATIVE COMMONS MAKES NO\nWARRANTIES REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR\nWORKS PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES\nRESULTING FROM THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS\nPROVIDED HEREUNDER.\nStatement of Purpose\nThe laws of most jurisdictions throughout the world automatically\nconfer exclusive Copyright and Related Rights (defined below) upon\nthe creator and subsequent owner(s) (each and all, an \"owner\") of an\noriginal work of authorship and/or a database (each, a \"Work\").\nCertain owners wish to permanently relinquish those rights to a Work\nfor the purpose of contributing to a commons of creative, cultural\nand scientific works (\"Commons\") that the public can reliably and\nwithout fear of later claims of infringement build upon, modify,\nincorporate in other works, reuse and redistribute as freely as\npossible in any form whatsoever and for any purposes, including\nwithout limitation commercial purposes. These owners may contribute\nto the Commons to promote the ideal of a free culture and the\nfurther production of creative, cultural and scientific works, or to\ngain reputation or greater distribution for their Work in part\nthrough the use and efforts of others.\nFor these and/or other purposes and motivations, and without any\nexpectation of additional consideration or compensation, the person\nassociating CC0 with a Work (the \"Affirmer\"), to the extent that he\nor she is an owner of Copyright and Related Rights in the Work,\nvoluntarily elects to apply CC0 to the Work and publicly distribute\nthe Work under its terms, with knowledge of his or her Copyright and\nRelated Rights in the Work and the meaning and intended legal effect\nof CC0 on those rights.\n1. Copyright and Related Rights.\nA Work made available under CC0 may be protected by copyright and\nrelated or neighboring rights (\"Copyright and Related Rights\").\nCopyright and Related Rights include, but are not limited to, the\nfollowing:\nthe right to reproduce, adapt, distribute, perform, display,\ncommunicate, and translate a Work;\nmoral rights retained by the original author(s) and/or\nperformer(s);\npublicity and privacy rights pertaining to a person's image or\nlikeness depicted in a Work;\nrights protecting against unfair competition in regards to a Work,\nsubject to the limitations in paragraph 4(a), below;\nrights protecting the extraction, dissemination, use and reuse of\ndata in a Work;\ndatabase rights (such as those arising under Directive 96/9/EC of\nthe European Parliament and of the Council of 11 March 1996 on the\nlegal protection of databases, and under any national\nimplementation thereof, including any amended or successor version\nof such directive); and\nother similar, equivalent or corresponding rights throughout the\nworld based on applicable law or treaty, and any national\nimplementations thereof.\n2. Waiver.\nTo the greatest extent permitted by, but not in contravention of,\napplicable law, Affirmer hereby overtly, fully, permanently,\nirrevocably and unconditionally waives, abandons, and surrenders all\nof Affirmer's Copyright and Related Rights and associated claims and\ncauses of action, whether now known or unknown (including existing\nas well as future claims and causes of action), in the Work (i) in\nall territories worldwide, (ii) for the maximum duration provided by\napplicable law or treaty (including future time extensions), (iii)\nin any current or future medium and for any number of copies, and\n(iv) for any purpose whatsoever, including without limitation\ncommercial, advertising or promotional purposes (the \"Waiver\").\nAffirmer makes the Waiver for the benefit of each member of the\npublic at large and to the detriment of Affirmer's heirs and\nsuccessors, fully intending that such Waiver shall not be subject to\nrevocation, rescission, cancellation, termination, or any other\nlegal or equitable action to disrupt the quiet enjoyment of the Work\nby the public as contemplated by Affirmer's express Statement of\nPurpose.\n3. Public License Fallback.\nShould any part of the Waiver for any reason be judged legally\ninvalid or ineffective under applicable law, then the Waiver shall\nbe preserved to the maximum extent permitted taking into account\nAffirmer's express Statement of Purpose. In addition, to the extent\nthe Waiver is so judged Affirmer hereby grants to each affected\nperson a royalty-free, non transferable, non sublicensable, non\nexclusive, irrevocable and unconditional license to exercise\nAffirmer's Copyright and Related Rights in the Work (i) in all\nterritories worldwide, (ii) for the maximum duration provided by\napplicable law or treaty (including future time extensions), (iii)\nin any current or future medium and for any number of copies, and\n(iv) for any purpose whatsoever, including without limitation\ncommercial, advertising or promotional purposes (the \"License\"). The\nLicense shall be deemed effective as of the date CC0 was applied by\nAffirmer to the Work. Should any part of the License for any reason\nbe judged legally invalid or ineffective under applicable law, such\npartial invalidity or ineffectiveness shall not invalidate the\nremainder of the License, and in such case Affirmer hereby affirms\nthat he or she will not (i) exercise any of his or her remaining\nCopyright and Related Rights in the Work or (ii) assert any\nassociated claims and causes of action with respect to the Work, in\neither case contrary to Affirmer's express Statement of Purpose.\n4. Limitations and Disclaimers.\nNo trademark or patent rights held by Affirmer are waived,\nabandoned, surrendered, licensed or otherwise affected by this\ndocument.\nAffirmer offers the Work as-is and makes no representations or\nwarranties of any kind concerning the Work, express, implied,\nstatutory or otherwise, including without limitation warranties of\ntitle, merchantability, fitness for a particular purpose, non\ninfringement, or the absence of latent or other defects, accuracy,\nor the present or absence of errors, whether or not discoverable,\nall to the greatest extent permissible under applicable law.\nAffirmer disclaims responsibility for clearing rights of other\npersons that may apply to the Work or any use thereof, including\nwithout limitation any person's Copyright and Related Rights in\nthe Work.
