-- Retrieves fleet properties, including metadata, status, and
-- configuration, for one or more fleets. You can request attributes for
-- all fleets, or specify a list of one or more fleet IDs. When requesting
-- all fleets, use the pagination parameters to retrieve results as a set
-- of sequential pages. If successful, a < FleetAttributes> object is
-- returned for each requested fleet ID. When specifying a list of fleet
-- IDs, attribute objects are returned only for fleets that currently
-- exist.
--
-- Some API actions may limit the number of fleet IDs allowed in one
-- request. If a request exceeds this limit, the request fails and the
-- error message includes the maximum allowed.
