-- Lists custom tape pools. You specify custom tape pools to list by
-- specifying one or more custom tape pool Amazon Resource Names (ARNs). If
-- you don\'t specify a custom tape pool ARN, the operation lists all
-- custom tape pools.
--
-- This operation supports pagination. You can optionally specify the
-- @Limit@ parameter in the body to limit the number of tape pools in the
-- response. If the number of tape pools returned in the response is
-- truncated, the response includes a @Marker@ element that you can use in
-- your subsequent request to retrieve the next set of tape pools.
--
-- This operation returns paginated results.
