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

+    extent this Public License may be interpreted as a contract, You are
+    granted the Licensed Rights in consideration of Your acceptance of

+    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

+         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,

+         and Similar Rights in Your contributions to Adapted Material in

+         closely related to copyright including, without limitation,
+         performance, broadcast, sound recording, and Sui Generis Database

+         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

+         License.

+         terms and conditions of this Public License, which are limited to

+

+         under this Public License.

+         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.
+    
+         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.
