		"Work" shall mean the work of authorship, whether in Source or
		Object form, made available under the License, as indicated by a
		copyright notice that is included in or attached to the work

		separable from, or merely link (or bind by name) to the interfaces of,
		the Work and Derivative Works thereof.

		"Contribution" shall mean any work of authorship, including
		the original version of the Work and any modifications or additions
		to that Work or Derivative Works thereof, that is intentionally
		submitted to Licensor for inclusion in the Work by the copyright owner

		the copyright owner. For the purposes of this definition, "submitted"
		means any form of electronic, verbal, or written communication sent
		to the Licensor or its representatives, including but not limited to

		excluding communication that is conspicuously marked or otherwise
		designated in writing by the copyright owner as "Not a Contribution."

		"Contributor" shall mean Licensor and any individual or Legal Entity
		on behalf of whom a Contribution has been received by Licensor and
		subsequently incorporated within the Work.

		2. Grant of Copyright License. Subject to the terms and conditions of
		this License, each Contributor hereby grants to You a perpetual,
		worldwide, non-exclusive, no-charge, royalty-free, irrevocable
		copyright license to reproduce, prepare Derivative Works of,
		publicly display, publicly perform, sublicense, and distribute the
		Work and such Derivative Works in Source or Object form.

		3. Grant of Patent License. Subject to the terms and conditions of
		this License, each Contributor hereby grants to You a perpetual,
		worldwide, non-exclusive, no-charge, royalty-free, irrevocable
		(except as stated in this section) patent license to make, have made,
		use, offer to sell, sell, import, and otherwise transfer the Work,
		where such license applies only to those patent claims licensable
		by such Contributor that are necessarily infringed by their
		Contribution(s) alone or by combination of their Contribution(s)
		with the Work to which such Contribution(s) was submitted. If You
		institute patent litigation against any entity (including a
		cross-claim or counterclaim in a lawsuit) alleging that the Work
		or a Contribution incorporated within the Work constitutes direct
		or contributory patent infringement, then any patent licenses
		granted to You under this License for that Work shall terminate
		as of the date such litigation is filed.

		4. Redistribution. You may reproduce and distribute copies of the
		Work or Derivative Works thereof in any medium, with or without
		modifications, and in Source or Object form, provided that You
		meet the following conditions:

		(a) You must give any other recipients of the Work or
		Derivative Works a copy of this License; and

		(b) You must cause any modified files to carry prominent notices
		stating that You changed the files; and

		(c) You must retain, in the Source form of any Derivative Works
		that You distribute, all copyright, patent, trademark, and
		attribution notices from the Source form of the Work,
		excluding those notices that do not pertain to any part of
		the Derivative Works; and

		(d) If the Work includes a "NOTICE" text file as part of its
		distribution, then any Derivative Works that You distribute must
		include a readable copy of the attribution notices contained
		within such NOTICE file, excluding those notices that do not
		pertain to any part of the Derivative Works, in at least one
		of the following places: within a NOTICE text file distributed
		as part of the Derivative Works; within the Source form or
		documentation, if provided along with the Derivative Works; or,
		within a display generated by the Derivative Works, if and
		wherever such third-party notices normally appear. The contents
		of the NOTICE file are for informational purposes only and
		do not modify the License. You may add Your own attribution
		notices within Derivative Works that You distribute, alongside
		or as an addendum to the NOTICE text from the Work, provided
		that such additional attribution notices cannot be construed
		as modifying the License.

		You may add Your own copyright statement to Your modifications and
		may provide additional or different license terms and conditions
		for use, reproduction, or distribution of Your modifications, or
		for any such Derivative Works as a whole, provided Your use,
		reproduction, and distribution of the Work otherwise complies with
		the conditions stated in this License.

		5. Submission of Contributions. Unless You explicitly state otherwise,
		any Contribution intentionally submitted for inclusion in the Work
		by You to the Licensor shall be under the terms and conditions of
		this License, without any additional terms or conditions.
		Notwithstanding the above, nothing herein shall supersede or modify
		the terms of any separate license agreement you may have executed
		with Licensor regarding such Contributions.

		6. Trademarks. This License does not grant permission to use the trade
		names, trademarks, service marks, or product names of the Licensor,
		except as required for reasonable and customary use in describing the
		origin of the Work and reproducing the content of the NOTICE file.

		7. Disclaimer of Warranty. Unless required by applicable law or
		agreed to in writing, Licensor provides the Work (and each
		Contributor provides its Contributions) on an "AS IS" BASIS,
		WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
		implied, including, without limitation, any warranties or conditions
		of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
		PARTICULAR PURPOSE. You are solely responsible for determining the
		appropriateness of using or redistributing the Work and assume any
		risks associated with Your exercise of permissions under this License.

		8. Limitation of Liability. In no event and under no legal theory,
		whether in tort (including negligence), contract, or otherwise,
		unless required by applicable law (such as deliberate and grossly
		negligent acts) or agreed to in writing, shall any Contributor be
		liable to You for damages, including any direct, indirect, special,
		incidental, or consequential damages of any character arising as a
		result of this License or out of the use or inability to use the
		Work (including but not limited to damages for loss of goodwill,
		work stoppage, computer failure or malfunction, or any and all
		other commercial damages or losses), even if such Contributor
		has been advised of the possibility of such damages.

		9. Accepting Warranty or Additional Liability. While redistributing
		the Work or Derivative Works thereof, You may choose to offer,
		and charge a fee for, acceptance of support, warranty, indemnity,
		or other liability obligations and/or rights consistent with this
		License. However, in accepting such obligations, You may act only
		on Your own behalf and on Your sole responsibility, not on behalf
		of any other Contributor, and only if You agree to indemnify,
		defend, and hold each Contributor harmless for any liability
		incurred by, or claims asserted against, such Contributor by reason
		of your accepting any such warranty or additional liability.
