+Ideally, the license terms of all files in the source tree should be
+defined by such License Identifiers; in no case a file can contain
+more than one such License Identifier list.
+
+If a "SPDX-License-Identifier:" line references more than one Unique
+License Identifier, then this means that the respective file can be
+used under the terms of either of these licenses, i. e. with
+
+	SPDX-License-Identifier:	GPL-2.0+	BSD-3-Clause
+
+you can choose between GPL-2.0+ and BSD-3-Clause licensing.
