-   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

-   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.
