-- | Deletes the messages in a queue specified by the queue URL.
--
-- When you use the 'PurgeQueue' API, the deleted messages in the queue cannot be
-- retrieved. When you purge a queue, the message deletion process takes up to
-- 60 seconds. All messages sent to the queue before calling 'PurgeQueue' will be
-- deleted; messages sent to the queue while it is being purged may be deleted.
-- While the queue is being purged, messages sent to the queue before 'PurgeQueue'
-- was called may be received, but will be deleted within the next minute.
