/**
 * <p>Lists and describes the versions of an Amazon Rekognition project. You can specify up to 10 model or
 *          adapter versions in <code>ProjectVersionArns</code>. If you don't specify a value,
 *          descriptions for all model/adapter versions in the project are returned.</p>
 *          <p>This operation requires permissions to perform the <code>rekognition:DescribeProjectVersions</code>
 *             action.</p>
 * @example
 * Use a bare-bones client and the command you need to make an API call.
