+ documentation, if provided along with the Derivative Works; or,\r
+ within a display generated by the Derivative Works, if and\r
+ wherever such third-party notices normally appear. The contents\r
+ of the NOTICE file are for informational purposes only and\r
+ do not modify the License. You may add Your own attribution\r
+ notices within Derivative Works that You distribute, alongside\r
+ or as an addendum to the NOTICE text from the Work, provided\r
+ that such additional attribution notices cannot be construed\r
+ as modifying the License.\r
+\r
+ You may add Your own copyright statement to Your modifications and\r

+ risks associated with Your exercise of permissions under this License.\r
+\r
+ 8. Limitation of Liability. In no event and under no legal theory,\r
+ whether in tort (including negligence), contract, or otherwise,\r
+ unless required by applicable law (such as deliberate and grossly\r
+ negligent acts) or agreed to in writing, shall any Contributor be\r
