-- Updates the settings that specify delivery of log files. Changes to a
-- trail do not require stopping the CloudTrail service. Use this action to
-- designate an existing bucket for log delivery. If the existing bucket
-- has previously been a target for CloudTrail log files, an IAM policy
-- exists for the bucket.
