-- Returns detailed information about one or more specified events.
-- Information includes standard event data (Amazon Web Services Region,
-- service, and so on, as returned by
-- <https://docs.aws.amazon.com/health/latest/APIReference/API_DescribeEvents.html DescribeEvents>),
-- a detailed event description, and possible additional metadata that
-- depends upon the nature of the event. Affected entities are not

-- If a specified event can\'t be retrieved, an error message is returned
-- for that event.
