+   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,

+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.
