	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. 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.


	Section 3 -- License Conditions.

						form), You must:

							a. retain the following if it is supplied by the Licensor

				 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-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;

		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.
