-- Returns detailed information about one or more specified events. Information includes standard event data (region, service, etc., as returned by 'DescribeEvents' ), a detailed event description, and possible additional metadata that depends upon the nature of the event. Affected entities are not included; to retrieve those, use the 'DescribeAffectedEntities' operation.
--
--
-- If a specified event cannot be retrieved, an error message is returned for that event.
