-- | Initiates the copy of an AMI from the specified source region to the region
-- in which the request was made. You specify the destination region by using
-- its endpoint when making the request. AMIs that use encrypted Amazon EBS
-- snapshots cannot be copied with this method. For more information, see
-- Copying AMIs in the Amazon Elastic Compute Cloud User Guide.
