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 other relationship. Creative
Commons makes its licenses and related information available on an "as-is"

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.

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 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 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 grants You such rights in consideration of benefits 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. 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 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.

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;

      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.

   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.

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.

c. 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.

d. 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.

e. 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.
