-- Deletes a CloudFront function.
--
-- You cannot delete a function if it\'s associated with a cache behavior.
-- First, update your distributions to remove the function association from
-- all cache behaviors, then delete the function.
--
-- To delete a function, you must provide the function\'s name and version
-- (@ETag@ value). To get these values, you can use @ListFunctions@ and
-- @DescribeFunction@.
