    CREATIVE COMMONS CORPORATION IS NOT A LAW FIRM AND DOES NOT PROVIDE
    LEGAL SERVICES. DISTRIBUTION OF THIS DOCUMENT DOES NOT CREATE AN
    ATTORNEY-CLIENT RELATIONSHIP. CREATIVE COMMONS PROVIDES THIS
    INFORMATION ON AN "AS-IS" BASIS. CREATIVE COMMONS MAKES NO WARRANTIES
    REGARDING THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS
    PROVIDED HEREUNDER, AND DISCLAIMS LIABILITY FOR DAMAGES RESULTING FROM
    THE USE OF THIS DOCUMENT OR THE INFORMATION OR WORKS PROVIDED
    HEREUNDER.

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.

Creative Commons Corporation ("Creative Commons") is not a law firm and

does not provide legal services or legal advice. Distribution of

Creative Commons public licenses does not create a lawyer-client or

Using Creative Commons Public Licenses



Creative Commons public licenses provide a standard set of terms and

conditions that creators and other rights holders may use to share

original works of authorship and other material subject to copyright

and certain other rights specified in the public license below. The

following considerations are for informational purposes only, are not

exhaustive, and do not form part of our licenses.



     Considerations for licensors: Our public licenses are

     intended for use by those authorized to give the public

     permission to use material in ways otherwise restricted by

     copyright and certain other rights. Our licenses are

     irrevocable. Licensors should read and understand the terms

     and conditions of the license they choose before applying it.

     Licensors should also secure all rights necessary before

     applying our licenses so that the public can reuse the

     material as expected. Licensors should clearly mark any

     material not subject to the license. This includes other CC-

     licensed material, or material used under an exception or

     limitation to copyright. More considerations for licensors:

    wiki.creativecommons.org/Considerations_for_licensors



     Considerations for the public: By using one of our public

     licenses, a licensor grants the public permission to use the

     licensed material under specified terms and conditions. If

     the licensor's permission is not necessary for any reason--for

     example, because of any applicable exception or limitation to

     copyright--then that use is not regulated by the license. Our

     licenses grant only permissions under copyright and certain

     other rights that a licensor has authority to grant. Use of

     the licensed material may still be restricted for other

     reasons, including because others have copyright or other

     rights in the material. A licensor may make special requests,

     such as asking that all changes be marked or described.

     Although not required by our licenses, you are encouraged to

     respect those requests where reasonable. More considerations

     for the public:

Creative Commons Attribution-NonCommercial-ShareAlike 4.0 International

Public License



By exercising the Licensed Rights (defined below), You accept and agree

to be bound by the terms and conditions of this Creative Commons

Attribution-NonCommercial-ShareAlike 4.0 International Public License

("Public License"). To the extent this Public License may be

interpreted as a contract, You are granted the Licensed Rights in

consideration of Your acceptance of these terms and conditions, and the

Licensor receives from making the Licensed Material available under

these terms and conditions.





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

     Licensor. For purposes of this Public License, where the Licensed

     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. BY-NC-SA Compatible License means a license listed at

     creativecommons.org/compatiblelicenses, approved by Creative

     Commons as essentially the equivalent of this Public License.



  d. 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.



  e. 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.



  f. 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.



  g. License Elements means the license attributes listed in the name

     of a Creative Commons Public License. The License Elements of this

     Public License are Attribution, NonCommercial, and ShareAlike.

     or other material to which the Licensor applied this Public

     License.



  i. 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.



  j. Licensor means the individual(s) or entity(ies) granting rights

     under this Public License.



  k. NonCommercial means not primarily intended for or directed towards

     commercial advantage or monetary compensation. For purposes of

     this Public License, the exchange of the Licensed Material for

     other material subject to Copyright and Similar Rights by digital

     file-sharing or similar means is NonCommercial provided there is

     no payment of monetary compensation in connection with the

     exchange.



  l. 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.



  m. Sui Generis Database Rights means rights other than copyright

     resulting from Directive 96/9/EC of the European Parliament and of

     the Council of 11 March 1996 on the legal protection of databases,

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

     equivalent rights anywhere in the world.



  n. 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, for NonCommercial purposes only; and



            b. produce, reproduce, and Share Adapted Material for

               NonCommercial purposes only.



       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. Additional offer from the Licensor -- Adapted Material.

               Every recipient of Adapted Material from You

               automatically receives an offer from the Licensor to

               exercise the Licensed Rights in the Adapted Material

               under the conditions of the Adapter's License You apply.



            c. 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, including when

          the Licensed Material is used other than for NonCommercial

          purposes.





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;



            b. indicate if You modified the Licensed Material and

               retain an indication of any previous modifications; and



            c. indicate the Licensed Material is licensed under this

               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.



  b. ShareAlike.



     In addition to the conditions in Section 3(a), if You Share

     Adapted Material You produce, the following conditions also apply.



       1. The Adapter's License You apply must be a Creative Commons

          license with the same License Elements, this version or

          later, or a BY-NC-SA Compatible License.



       2. You must include the text of, or the URI or hyperlink to, the

          Adapter's License You apply. You may satisfy this condition

          in any reasonable manner based on the medium, means, and

          context in which You Share Adapted Material.



       3. You may not offer or impose any additional or different terms

          or conditions on, or apply any Effective Technological

          Measures to, Adapted Material that restrict exercise of the

          rights granted under the Adapter's License You apply.





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 for NonCommercial purposes

     only;



  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,

     including for purposes of Section 3(b); 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.



  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE

     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,

     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,

     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,

     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR

     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN

     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR

     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR

     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.



  c. The disclaimer of warranties and limitation of liability provided

     above shall be interpreted in a manner that, to the extent

     possible, most closely approximates an absolute disclaimer and

     waiver of all liability.





Section 6 -- Term and Termination.



  a. This Public License applies for the term of the Copyright and

     Similar Rights licensed here. However, if You fail to comply with

     this Public License, then Your rights under this Public License

     terminate automatically.



  b. Where Your right to use the Licensed Material has terminated under

     Section 6(a), it reinstates:



       1. automatically as of the date the violation is cured, provided

          it is cured within 30 days of Your discovery of the

          violation; or



       2. upon express reinstatement by the Licensor.



     For the avoidance of doubt, this Section 6(b) does not affect any

     right the Licensor may have to seek remedies for Your violations

     of this Public License.



  c. For the avoidance of doubt, the Licensor may also offer the

     Licensed Material under separate terms or conditions or stop

     distributing the Licensed Material at any time; however, doing so

     will not terminate this Public License.



  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public

     License.





Section 7 -- Other Terms and Conditions.



  a. The Licensor shall not be bound by any additional or different

     terms or conditions communicated by You unless expressly agreed.



  b. Any arrangements, understandings, or agreements regarding the

     Licensed Material not stated herein are separate from and

     independent of the terms and conditions of this Public License.





Section 8 -- Interpretation.



  a. For the avoidance of doubt, this Public License does not, and

     shall not be interpreted to, reduce, limit, restrict, or impose

     conditions on any use of the Licensed Material that could lawfully

     be made without permission under this Public License.



  b. To the extent possible, if any provision of this Public License is

     deemed unenforceable, it shall be automatically reformed to the

     minimum extent necessary to make it enforceable. If the provision

     cannot be reformed, it shall be severed from this Public License

     without affecting the enforceability of the remaining terms and

     conditions.



  c. No term or condition of this Public License will be waived and no

     failure to comply consented to unless expressly agreed to by the

     Licensor.



  d. Nothing in this Public License constitutes or may be interpreted

     as a limitation upon, or waiver of, any privileges and immunities

     that apply to the Licensor or You, including from the legal

     processes of any jurisdiction or authority.
