 All PulseAudio source files are licensed under the GNU Lesser General Public
 License. (see file LGPL for details)
 
-However, the server side links to the GPL-only library 'libsamplerate' which
-practically downgrades the license of the server part to GPL (see file GPL for
-details), exercising section 3 of the LGPL.
-
-Hence you should treat the client library ('libpulse') of PulseAudio as being
-LGPL licensed and the server part ('libpulsecore') as being GPL licensed. Since
-the PulseAudio daemon and the modules link to 'libpulsecore' they are of course
-also GPL licensed.
+However, the server side has optional GPL dependencies.  These include the
+libsamplerate (for core libraries) and bluez (for the bluetooth proximity helper
+program) libraries, although others may also be included in the future.  If
+PulseAudio is compiled with these optional components, this effectively
+downgrades the license of the server part to GPL (see file GPL for details),
+exercising section 3 of the LGPL. In such circumstances, you should treat the
+client library (libpulse) of PulseAudio as being LGPL licensed and the server
+part (libpulsecore) as being GPL licensed. Since the PulseAudio daemon, tests,
+various utilities/helpers and the modules link to libpulsecore and/or the
+afore mentioned optional GPL dependencies they are of course also GPL licensed
+also in this scenario.
 
 Andre Adrian's echo cancellation implementation is licensed under a less
 restrictive license - see src/modules/echo-cancel/adrian-license.txt for
 details.
 
--- Lennart Poettering, April 20th, 2006.
+Some other files pulled into PA source (i.e. reference implementations that are
+considered too small and stable to be considered as an external library) use the
+more permissive MIT license. This include the device reservation DBus protocol
+and realtime kit implementations.
+
+Additionally, a more permissive Sun license is used for code that performs
+u-law, A-law and linear PCM conversions.
+
+While we attempt to provide a summary here, it is the ultimate responsibility of
+the packager to ensure the components they use in their build of PulseAudio
+meets their license requirements.
