+SWUpdate is Free Software.  It is copyrighted by Stefano Babic and
+many others who contributed code (see the actual source code and the
+git commit messages for details).  You can redistribute SWUpdate and/or
+modify it under the terms of version 2 of the GNU General Public
+License as published by the Free Software Foundation.  Most of it can
+also be distributed, at your option, under any later version of the
+GNU General Public License -- see individual files for exceptions.
+
+To make this easier, license headers in the source files will be
+replaced with a single line reference to Unique License Identifiers
+as defined by the Linux Foundation's SPDX project [1].  For example,
+in a source file the full "GPL v2.0 or later" header text will be
+replaced by a single line:
+
+::
+
+	SPDX-License-Identifier:	GPL-2.0+
+
+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.
