-- | Adds or removes permission settings for the specified snapshot. You may add
-- or remove specified AWS account IDs from a snapshot's list of create volume
-- permissions, but you cannot do both in a single API call. If you need to
-- both add and remove account IDs for a snapshot, you must use multiple API
-- calls. For more information on modifying snapshot permissions, see Sharing
-- Snapshots in the Amazon Elastic Compute Cloud User Guide.
