-- Returns the Cross-Origin Resource Sharing (CORS) configuration

--
-- To use this operation, you must have permission to perform the
-- @s3:GetBucketCORS@ action. By default, the bucket owner has this
-- permission and can grant it to others.
--
-- For more information about CORS, see
-- <https://docs.aws.amazon.com/AmazonS3/latest/dev/cors.html Enabling Cross-Origin Resource Sharing>.
