+
+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 :

+ Rights.

+
+Section 2 - Scope.

+ 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.
+

+ 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.

+ 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.
+

+ 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,

+ voluntary or waivable statutory or compulsory licensing
+ scheme. In all other cases the Licensor expressly reserves any
+ right to collect such royalties.

+
+ 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

+ 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, 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

+
+ 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

+ most closely approximates an absolute disclaimer and waiver of all
+ liability.
+

+ 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
