-- This operation returns information about a vault, including the vault\'s
-- Amazon Resource Name (ARN), the date the vault was created, the number
-- of archives it contains, and the total size of all the archives in the
-- vault. The number of archives and their total size are as of the last
-- inventory generation. This means that if you add or remove an archive
-- from a vault, and then immediately use Describe Vault, the change in
-- contents will not be immediately reflected. If you want to retrieve the
-- latest inventory of the vault, use InitiateJob. Amazon Glacier generates
-- vault inventories approximately daily. For more information, see
-- <http://docs.aws.amazon.com/amazonglacier/latest/dev/vault-inventory.html Downloading a Vault Inventory in Amazon Glacier>.
--
-- An AWS account has full permission to perform all operations (actions).
-- However, AWS Identity and Access Management (IAM) users don\'t have any
-- permissions by default. You must grant them explicit permission to
-- perform specific actions. For more information, see
