-- Returns information about the specified Amazon Redshift HSM
-- configuration. If no configuration ID is specified, returns information
-- about all the HSM configurations owned by your AWS customer account.
--
-- If you specify both tag keys and tag values in the same request, Amazon
-- Redshift returns all HSM connections that match any combination of the
-- specified keys and values. For example, if you have 'owner' and
-- 'environment' for tag keys, and 'admin' and 'test' for tag values, all
-- HSM connections that have any combination of those values are returned.
--
-- If both tag keys and values are omitted from the request, HSM
-- connections are returned regardless of whether they have tag keys or
-- values associated with them.

-- | A tag value or values for which you want to return all matching HSM
-- configurations that are associated with the specified tag value or
-- values. For example, suppose that you have HSM configurations that are
-- tagged with values called 'admin' and 'test'. If you specify both of

-- the HSM configurations that have either or both of these tag values
-- associated with them.

-- | An optional parameter that specifies the starting point to return a set
-- of response records. When the results of a DescribeHsmConfigurations
-- request exceed the value specified in 'MaxRecords', AWS returns a value
-- in the 'Marker' field of the response. You can retrieve the next set of
-- response records by providing the returned marker value in the 'Marker'
-- parameter and retrying the request.

-- | The maximum number of response records to return in each call. If the

-- value, a value is returned in a 'marker' field of the response. You can
-- retrieve the next set of records by retrying the command with the
-- returned marker value.
