+ contract, You are granted the Licensed Rights in consideration of Your

+ Section 1 -- Definitions.
+ .
+ a. Adapted Material means material subject to Copyright and Similar
+ Rights that is derived from or based upon the Licensed Material
+ and in which the Licensed Material is translated, altered,
+ arranged, transformed, or otherwise modified in a manner requiring
+ permission under the Copyright and Similar Rights held by the

+ Material is a musical work, performance, or sound recording,
+ Adapted Material is always produced where the Licensed Material is
+ synched in timed relation with a moving image.
+ .
+ b. Adapter's License means the license You apply to Your Copyright
+ and Similar Rights in Your contributions to Adapted Material in
+ accordance with the terms and conditions of this Public License.
+ .
+ c. Copyright and Similar Rights means copyright and/or similar rights
+ closely related to copyright including, without limitation,
+ performance, broadcast, sound recording, and Sui Generis Database
+ Rights, without regard to how the rights are labeled or
+ categorized. For purposes of this Public License, the rights
+ specified in Section 2(b)(1)-(2) are not Copyright and Similar
+ Rights.
+ .
+ d. Effective Technological Measures means those measures that, in the
+ absence of proper authority, may not be circumvented under laws
+ fulfilling obligations under Article 11 of the WIPO Copyright
+ Treaty adopted on December 20, 1996, and/or similar international
+ agreements.
+ .
+ e. Exceptions and Limitations means fair use, fair dealing, and/or
+ any other exception or limitation to Copyright and Similar Rights
+ that applies to Your use of the Licensed Material.

+ f. Licensed Material means the artistic or literary work, database,
+ or other material to which the Licensor applied this Public
+ License.
+ .
+ g. Licensed Rights means the rights granted to You subject to the
+ terms and conditions of this Public License, which are limited to
+ all Copyright and Similar Rights that apply to Your use of the
+ Licensed Material and that the Licensor has authority to license.
+ .
+ h. Licensor means the individual(s) or entity(ies) granting rights
+ under this Public License.
+ .
+ i. Share means to provide material to the public by any means or
+ process that requires permission under the Licensed Rights, such
+ as reproduction, public display, public performance, distribution,
+ dissemination, communication, or importation, and to make material
+ available to the public including in ways that members of the
+ public may access the material from a place and at a time
+ individually chosen by them.
+ .
+ j. Sui Generis Database Rights means rights other than copyright
+ resulting from Directive 96/9/EC of the European Parliament and of

+ as amended and/or succeeded, as well as other essentially

+ .
+ k. You means the individual or entity exercising the Licensed Rights
+ under this Public License. Your has a corresponding meaning.
+ .
+ Section 2 -- Scope.
+ .
+ a. License grant.
+ .
+ 1. Subject to the terms and conditions of this Public License,
+ the Licensor hereby grants You a worldwide, royalty-free,
+ non-sublicensable, non-exclusive, irrevocable license to
+ exercise the Licensed Rights in the Licensed Material to:
+ .
+ a. reproduce and Share the Licensed Material, in whole or
+ in part; and
+ .
+ b. produce, reproduce, and Share Adapted Material.
+ .
+ 2. Exceptions and Limitations. For the avoidance of doubt, where
+ Exceptions and Limitations apply to Your use, this Public
+ License does not apply, and You do not need to comply with
+ its terms and conditions.
+ .
+ 3. Term. The term of this Public License is specified in Section
+ 6(a).
+ .
+ 4. Media and formats; technical modifications allowed. The
+ Licensor authorizes You to exercise the Licensed Rights in
+ all media and formats whether now known or hereafter created,
+ and to make technical modifications necessary to do so. The
+ Licensor waives and/or agrees not to assert any right or
+ authority to forbid You from making technical modifications
+ necessary to exercise the Licensed Rights, including
+ technical modifications necessary to circumvent Effective
+ Technological Measures. For purposes of this Public License,
+ simply making modifications authorized by this Section 2(a)
+ (4) never produces Adapted Material.
+ .
+ 5. Downstream recipients.
+ .
+ a. Offer from the Licensor -- Licensed Material. Every
+ recipient of the Licensed Material automatically
+ receives an offer from the Licensor to exercise the
+ Licensed Rights under the terms and conditions of this
+ Public License.
+ .
+ b. No downstream restrictions. You may not offer or impose
+ any additional or different terms or conditions on, or
+ apply any Effective Technological Measures to, the
+ Licensed Material if doing so restricts exercise of the
+ Licensed Rights by any recipient of the Licensed
+ Material.
+ .
+ 6. No endorsement. Nothing in this Public License constitutes or
+ may be construed as permission to assert or imply that You
+ are, or that Your use of the Licensed Material is, connected
+ with, or sponsored, endorsed, or granted official status by,
+ the Licensor or others designated to receive attribution as
+ provided in Section 3(a)(1)(A)(i).
+ .
+ b. Other rights.
+ .
+ 1. Moral rights, such as the right of integrity, are not
+ licensed under this Public License, nor are publicity,
+ privacy, and/or other similar personality rights; however, to
+ the extent possible, the Licensor waives and/or agrees not to
+ assert any such rights held by the Licensor to the limited
+ extent necessary to allow You to exercise the Licensed
+ Rights, but not otherwise.
+ .
+ 2. Patent and trademark rights are not licensed under this
+ Public License.
+ .
+ 3. To the extent possible, the Licensor waives any right to
+ collect royalties from You for the exercise of the Licensed
+ Rights, whether directly or through a collecting society
+ under any voluntary or waivable statutory or compulsory
+ licensing scheme. In all other cases the Licensor expressly
+ reserves any right to collect such royalties.
+ .
+ Section 3 -- License Conditions.
+ .
+ Your exercise of the Licensed Rights is expressly made subject to the
+ following conditions.
+ .
+ a. Attribution.
+ .
+ 1. If You Share the Licensed Material (including in modified
+ form), You must:
+ .
+ a. retain the following if it is supplied by the Licensor
+ with the Licensed Material:
+ .
+ i. identification of the creator(s) of the Licensed
+ Material and any others designated to receive
+ attribution, in any reasonable manner requested by
+ the Licensor (including by pseudonym if
+ designated);
+ .
+ ii. a copyright notice;
+ .
+ iii. a notice that refers to this Public License;
+ .
+ iv. a notice that refers to the disclaimer of
+ warranties;
+ .
+ v. a URI or hyperlink to the Licensed Material to the
+ extent reasonably practicable;
+ .

+ retain an indication of any previous modifications; and

+ Public License, and include the text of, or the URI or
+ hyperlink to, this Public License.
+ .
+ 2. You may satisfy the conditions in Section 3(a)(1) in any
+ reasonable manner based on the medium, means, and context in
+ which You Share the Licensed Material. For example, it may be
+ reasonable to satisfy the conditions by providing a URI or
+ hyperlink to a resource that includes the required
+ information.
+ .
+ 3. If requested by the Licensor, You must remove any of the
+ information required by Section 3(a)(1)(A) to the extent
+ reasonably practicable.
+ .
+ 4. If You Share Adapted Material You produce, the Adapter's
+ License You apply must not prevent recipients of the Adapted
+ Material from complying with this Public License.
+ .
+ Section 4 -- Sui Generis Database Rights.
+ .
+ Where the Licensed Rights include Sui Generis Database Rights that
+ apply to Your use of the Licensed Material:
+ .
+ a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+ to extract, reuse, reproduce, and Share all or a substantial
+ portion of the contents of the database;
+ .
+ b. if You include all or a substantial portion of the database
+ contents in a database in which You have Sui Generis Database
+ Rights, then the database in which You have Sui Generis Database
+ Rights (but not its individual contents) is Adapted Material; and
+ .
+ c. You must comply with the conditions in Section 3(a) if You Share
+ all or a substantial portion of the contents of the database.
+ .
+ For the avoidance of doubt, this Section 4 supplements and does not
+ replace Your obligations under this Public License where the Licensed
+ Rights include other Copyright and Similar Rights.
+ .
+ Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+ .
+ a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+ EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+ AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+ ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+ IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+ WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+ PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+ ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+ KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+ ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.

- THE WORK (AS DEFINED BELOW) IS PROVIDED UNDER THE TERMS OF THIS CREATIVE
- COMMONS PUBLIC LICENSE ("CCPL" OR "LICENSE"). THE WORK IS PROTECTED BY
- COPYRIGHT AND/OR OTHER APPLICABLE LAW. ANY USE OF THE WORK OTHER THAN AS

+ Section 6 -- Term and Termination.

- BY EXERCISING ANY RIGHTS TO THE WORK PROVIDED HERE, YOU ACCEPT AND AGREE
- TO BE BOUND BY THE TERMS OF THIS LICENSE. TO THE EXTENT THIS LICENSE MAY
- BE CONSIDERED TO BE A CONTRACT, THE LICENSOR GRANTS YOU THE RIGHTS
- CONTAINED HERE IN CONSIDERATION OF YOUR ACCEPTANCE OF SUCH TERMS AND
- CONDITIONS.
+ a. This Public License applies for the term of the Copyright and
+ Similar Rights licensed here. However, if You fail to comply with

- artistic work, or phonogram or performance and includes cinematographic
- adaptations or any other form in which the Work may be recast,
- transformed, or adapted including in any form recognizably derived from
- the original, except that a work that constitutes a Collection will not
- be considered an Adaptation for the purpose of this License. For the
- avoidance of doubt, where the Work is a musical work, performance or

- moving image ("synching") will be considered an Adaptation for the
- purpose of this License.
- .
- b. "Collection" means a collection of literary or artistic works, such
- as encyclopedias and anthologies, or performances, phonograms or
- broadcasts, or other works or subject matter other than works listed in
- Section 1(f) below, which, by reason of the selection and arrangement of
- their contents, constitute intellectual creations, in which the Work is
- included in its entirety in unmodified form along with one or more other
- contributions, each constituting separate and independent works in
- themselves, which together are assembled into a collective whole. A work
- that constitutes a Collection will not be considered an Adaptation (as
- defined above) for the purposes of this License.

- copies of the Work or Adaptation, as appropriate, through sale or other

- if no individual or entity can be identified, the publisher; and in
- addition (i) in the case of a performance the actors, singers,
- musicians, dancers, and other persons who act, sing, deliver, declaim,
- play in, interpret or otherwise perform literary or artistic works or

- terms of this License including without limitation any production in the
- literary, scientific and artistic domain, whatever may be the mode or
- form of its expression including digital form, such as a book, pamphlet
- and other writing; a lecture, address, sermon or other work of the same
- nature; a dramatic or dramatico-musical work; a choreographic work or

- compilation of data to the extent it is protected as a copyrightable
- work; or a work performed by a variety or circus performer to the extent

- g. "You" means an individual or entity exercising rights under this
- License who has not previously violated the terms of this License with
- respect to the Work, or who has received express permission from the
- Licensor to exercise rights under this License despite a previous
- violation.
- .
- h. "Publicly Perform" means to perform public recitations of the Work
- and to communicate to the public those public recitations, by any means
- or process, including by wire or wireless means or public digital
- performances; to make available to the public Works in such a way that
- members of the public may access these Works from a place and at a place
- individually chosen by them; to perform the Work to the public by any
- means or process and the communication to the public of the performances
- of the Work, including by public digital performance; to broadcast and
- rebroadcast the Work by any means including signs, sounds or images.
- .
- i. "Reproduce" means to make copies of the Work by any means including
- without limitation by sound or visual recordings and the right of
- fixation and reproducing fixations of the Work, including storage of a
- protected performance or phonogram in digital form or other electronic
- medium.
- .
- 2. Fair Dealing Rights. Nothing in this License is intended to reduce,
- limit, or restrict any uses free from copyright or rights arising from
- limitations or exceptions that are provided for in connection with the
- copyright protection under copyright law or other applicable laws.
- .
- 3. License Grant. Subject to the terms and conditions of this License,
- Licensor hereby grants You a worldwide, royalty-free, non-exclusive,
- perpetual (for the duration of the applicable copyright) license to
- exercise the rights in the Work as stated below:
- .
- a. to Reproduce the Work, to incorporate the Work into one or more
- Collections, and to Reproduce the Work as incorporated in the
- Collections;
- .
- b. to create and Reproduce Adaptations provided that any such
- Adaptation, including any translation in any medium, takes reasonable
- steps to clearly label, demarcate or otherwise identify that changes
- were made to the original Work. For example, a translation could be
- marked "The original work was translated from English to Spanish," or a
- modification could indicate "The original work has been modified.";
- .
- c. to Distribute and Publicly Perform the Work including as incorporated
- in Collections; and,
- .
- d. to Distribute and Publicly Perform Adaptations.
- .
- e. For the avoidance of doubt:
- .
- i. Non-waivable Compulsory License Schemes. In those jurisdictions in
- which the right to collect royalties through any statutory or compulsory
- licensing scheme cannot be waived, the Licensor reserves the exclusive
- right to collect such royalties for any exercise by You of the rights
- granted under this License;
- .
- ii. Waivable Compulsory License Schemes. In those jurisdictions in which
- the right to collect royalties through any statutory or compulsory
- licensing scheme can be waived, the Licensor waives the exclusive right
- to collect such royalties for any exercise by You of the rights granted
- under this License; and,
- .
- iii. Voluntary License Schemes. The Licensor waives the right to collect
- royalties, whether individually or, in the event that the Licensor is a
- member of a collecting society that administers voluntary licensing
- schemes, via that society, from any exercise by You of the rights
- granted under this License.
- .
- The above rights may be exercised in all media and formats whether now
- known or hereafter devised. The above rights include the right to make
- such modifications as are technically necessary to exercise the rights
- in other media and formats. Subject to Section 8(f), all rights not
- expressly granted by Licensor are hereby reserved.
- .
- 4. Restrictions. The license granted in Section 3 above is expressly
- made subject to and limited by the following restrictions:
- .
- a. You may Distribute or Publicly Perform the Work only under the terms
- of this License. You must include a copy of, or the Uniform Resource
- Identifier (URI) for, this License with every copy of the Work You
- Distribute or Publicly Perform. You may not offer or impose any terms on
- the Work that restrict the terms of this License or the ability of the
- recipient of the Work to exercise the rights granted to that recipient
- under the terms of the License. You may not sublicense the Work. You
- must keep intact all notices that refer to this License and to the
- disclaimer of warranties with every copy of the Work You Distribute or
- Publicly Perform. When You Distribute or Publicly Perform the Work, You
- may not impose any effective technological measures on the Work that
- restrict the ability of a recipient of the Work from You to exercise the
- rights granted to that recipient under the terms of the License. This
- Section 4(a) applies to the Work as incorporated in a Collection, but
- this does not require the Collection apart from the Work itself to be
- made subject to the terms of this License. If You create a Collection,
- upon notice from any Licensor You must, to the extent practicable,
- remove from the Collection any credit as required by Section 4(b), as
- requested. If You create an Adaptation, upon notice from any Licensor
- You must, to the extent practicable, remove from the Adaptation any
- credit as required by Section 4(b), as requested.
- .
- b. If You Distribute, or Publicly Perform the Work or any Adaptations or
- Collections, You must, unless a request has been made pursuant to
- Section 4(a), keep intact all copyright notices for the Work and
- provide, reasonable to the medium or means You are utilizing: (i) the
- name of the Original Author (or pseudonym, if applicable) if supplied,
- and/or if the Original Author and/or Licensor designate another party or
- parties (e.g., a sponsor institute, publishing entity, journal) for
- attribution ("Attribution Parties") in Licensor's copyright notice,
- terms of service or by other reasonable means, the name of such party or
- parties; (ii) the title of the Work if supplied; (iii) to the extent
- reasonably practicable, the URI, if any, that Licensor specifies to be
- associated with the Work, unless such URI does not refer to the
- copyright notice or licensing information for the Work; and (iv) ,
- consistent with Section 3(b), in the case of an Adaptation, a credit
- identifying the use of the Work in the Adaptation (e.g., "French
- translation of the Work by Original Author," or "Screenplay based on
- original Work by Original Author"). The credit required by this Section
- 4 (b) may be implemented in any reasonable manner; provided, however,
- that in the case of a Adaptation or Collection, at a minimum such credit
- will appear, if a credit for all contributing authors of the Adaptation
- or Collection appears, then as part of these credits and in a manner at
- least as prominent as the credits for the other contributing authors.
- For the avoidance of doubt, You may only use the credit required by this
- Section for the purpose of attribution in the manner set out above and,
- by exercising Your rights under this License, You may not implicitly or
- explicitly assert or imply any connection with, sponsorship or
- endorsement by the Original Author, Licensor and/or Attribution Parties,
- as appropriate, of You or Your use of the Work, without the separate,
- express prior written permission of the Original Author, Licensor and/or
- Attribution Parties.
- .
- c. Except as otherwise agreed in writing by the Licensor or as may be
- otherwise permitted by applicable law, if You Reproduce, Distribute or
- Publicly Perform the Work either by itself or as part of any Adaptations
- or Collections, You must not distort, mutilate, modify or take other
- derogatory action in relation to the Work which would be prejudicial to
- the Original Author's honor or reputation. Licensor agrees that in those
- jurisdictions (e.g. Japan), in which any exercise of the right granted
- in Section 3(b) of this License (the right to make Adaptations) would be
- deemed to be a distortion, mutilation, modification or other derogatory
- action prejudicial to the Original Author's honor and reputation, the
- Licensor will waive or not assert, as appropriate, this Section, to the
- fullest extent permitted by the applicable national law, to enable You
- to reasonably exercise Your right under Section 3(b) of this License
- (right to make Adaptations) but not otherwise.
- .
- 5. Representations, Warranties and Disclaimer
- .
- UNLESS OTHERWISE MUTUALLY AGREED TO BY THE PARTIES IN WRITING, LICENSOR
- 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, MERCHANTIBILITY,
- FITNESS FOR A PARTICULAR PURPOSE, NONINFRINGEMENT, OR THE ABSENCE OF
- LATENT OR OTHER DEFECTS, ACCURACY, OR THE PRESENCE OF ABSENCE OF ERRORS,
- WHETHER OR NOT DISCOVERABLE. SOME JURISDICTIONS DO NOT ALLOW THE
- EXCLUSION OF IMPLIED WARRANTIES, SO SUCH EXCLUSION MAY NOT APPLY TO YOU.
- .
- 6. Limitation on Liability. EXCEPT TO THE EXTENT REQUIRED BY APPLICABLE
- LAW, IN NO EVENT WILL LICENSOR BE LIABLE TO YOU ON ANY LEGAL THEORY FOR
- ANY SPECIAL, INCIDENTAL, CONSEQUENTIAL, PUNITIVE OR EXEMPLARY DAMAGES
- ARISING OUT OF THIS LICENSE OR THE USE OF THE WORK, EVEN IF LICENSOR HAS
- BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
- .
- 7. Termination
- .
- a. This License and the rights granted hereunder will terminate
- automatically upon any breach by You of the terms of this License.
- Individuals or entities who have received Adaptations or Collections
- from You under this License, however, will not have their licenses
- terminated provided such individuals or entities remain in full
- compliance with those licenses. Sections 1, 2, 5, 6, 7, and 8 will
- survive any termination of this License.
- .
- b. Subject to the above terms and conditions, the license granted here
- is perpetual (for the duration of the applicable copyright in the Work).
- Notwithstanding the above, Licensor reserves the right to release the
- Work under different license terms or to stop distributing the Work at
- any time; provided, however that any such election will not serve to
- withdraw this License (or any other license that has been, or is
- required to be, granted under the terms of this License), and this
- License will continue in full force and effect unless terminated as
- stated above.
- .
- 8. Miscellaneous
- .
- a. Each time You Distribute or Publicly Perform the Work or a
- Collection, the Licensor offers to the recipient a license to the Work
- on the same terms and conditions as the license granted to You under
- this License.
- .
- b. Each time You Distribute or Publicly Perform an Adaptation, Licensor
- offers to the recipient a license to the original Work on the same terms
- and conditions as the license granted to You under this License.
- .
- c. If any provision of this License is invalid or unenforceable under
- applicable law, it shall not affect the validity or enforceability of
- the remainder of the terms of this License, and without further action
- by the parties to this agreement, such provision shall be reformed to
- the minimum extent necessary to make such provision valid and
- enforceable.
- .
- d. No term or provision of this License shall be deemed waived and no
- breach consented to unless such waiver or consent shall be in writing
- and signed by the party to be charged with such waiver or consent. This
- License constitutes the entire agreement between the parties with
- respect to the Work licensed here. There are no understandings,
- agreements or representations with respect to the Work not specified
- here. Licensor shall not be bound by any additional provisions that may
- appear in any communication from You.
- .
- e. This License may not be modified without the mutual written agreement
- of the Licensor and You.
- .
- f. The rights granted under, and the subject matter referenced, in this
- License were drafted utilizing the terminology of the Berne Convention
- for the Protection of Literary and Artistic Works (as amended on
- September 28, 1979), the Rome Convention of 1961, the WIPO Copyright
- Treaty of 1996, the WIPO Performances and Phonograms Treaty of 1996 and
- the Universal Copyright Convention (as revised on July 24, 1971). These
- rights and subject matter take effect in the relevant jurisdiction in
- which the License terms are sought to be enforced according to the
- corresponding provisions of the implementation of those treaty
- provisions in the applicable national law. If the standard suite of
- rights granted under applicable copyright law includes additional rights
- not granted under this License, such additional rights are deemed to be
- included in the License; this License is not intended to restrict the
- license of any rights under applicable law.

It differs from MSAA which takes multiple coverage samples while rendering objects.

+ * Experimental: Cluster bounds generator
+ * Creates bounding volumes that can be used for frustum, backface and occlusion culling.
+ *
+ * For backface culling with orthographic projection, use the following formula to reject backfacing clusters:
+ *   dot(view, cone_axis) >= cone_cutoff
+ *
+ * For perspective projection, you can the formula that needs cone apex in addition to axis & cutoff:
+ *   dot(normalize(cone_apex - camera_position), cone_axis) >= cone_cutoff
+ *
+ * Alternatively, you can use the formula that doesn't need cone apex and uses bounding sphere instead:
+ *   dot(normalize(center - camera_position), cone_axis) >= cone_cutoff + radius / length(center - camera_position)
+ * or an equivalent formula that doesn't have a singularity at center = camera_position:
+ *   dot(center - camera_position, cone_axis) >= cone_cutoff * length(center - camera_position) + radius
+ *
+ * The formula that uses the apex is slightly more accurate but needs the apex; if you are already using bounding sphere
+ * to do frustum/occlusion culling, the formula that doesn't use the apex may be preferable.
+ *
+ * vertex_positions should have float3 position in the first 12 bytes of each vertex - similar to glVertexPointer
+ * index_count should be less than or equal to 256*3 (the function assumes clusters of limited size)

+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.
