/**
 * <p>Lists descriptions of all the Amazon Redshift event notification subscriptions for a
 *             customer account. If you specify a subscription name, lists the description for that
 *             subscription.</p>
 *          <p>If you specify both tag keys and tag values in the same request, Amazon Redshift returns
 *             all event notification subscriptions that match any combination of the specified keys
 *             and values. For example, if you have <code>owner</code> and <code>environment</code> for
 *             tag keys, and <code>admin</code> and <code>test</code> for tag values, all subscriptions
 *             that have any combination of those values are returned.</p>
 *          <p>If both tag keys and values are omitted from the request, subscriptions are
 *             returned regardless of whether they have tag keys or values associated with
 *             them.</p>

 * Use a bare-bones client and the command you need to make an API call.
