/**
 * <p>Gets information about CloudHSM clusters.</p>
 *          <p>This is a paginated operation, which means that each response might contain only a
 *       subset of all the clusters. When the response contains only a subset of clusters, it includes
 *       a <code>NextToken</code> value. Use this value in a subsequent <code>DescribeClusters</code>
 *       request to get more clusters. When you receive a response with no <code>NextToken</code> (or
 *       an empty or null value), that means there are no more clusters to get.</p>
 *          <p>
 *             <b>Cross-account use:</b> No. You cannot perform this operation on CloudHSM clusters in a different Amazon Web Services account.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
