+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,

+any and all other commercial damages or losses), even if such Contributor has
+been advised of the possibility of such damages.
+
