dbus/COPYING

dbus is licensed to you under your choice of the Academic Free
License version 2.1, or the GNU General Public License version 2
(or, at your option any later version).
The full text of these licenses can be found in LICENSES/AFL-2.1.txt
and LICENSES/GPL-2.0-or-later.txt.

Some source files are under more permissive BSD-/MIT-style licenses
that are compatible with the AFL and GPL.

When contributing new code, our preferred license for new code is the
version of the MIT/X11 license used by the Expat library, referred to
as "MIT" by SPDX, which can be found in LICENSES/MIT.txt.

Some of the standalone binaries are under the GPL only; in particular,
but not limited to, tools/dbus-cleanup-sockets.c and test/decode-gcov.c.

Each source code file is marked with the proper copyright information -
if you find a file that isn't marked please bring it to our attention.

Some files contain a SPDX-License-Identifier marker. These markers
indicate the license of that file, consistent with the SPDX and REUSE
specifications: see <https://reuse.software/>. dbus is not yet fully
REUSE-compliant, and not all files carry these markers.
