This package was debianized by CJ van den Berg <cj@vdbonline.com> on

================
Lennart Poettering <poettering@users.sourceforge.net>
Pierre Ossman <drzeus@drzeus.cx>,
through his employer Cendio <http://www.cendio.com/>
Licensing
=========
The upstream license clarifies pretty well that the sources of pulseaudio are
LGPL (please see LGPL license grant below), but that some parts will be
effectively GPL since they rely on GPL libraries, quoting the upstream
LICENSE:
"""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.
-- Lennart Poettering, April 20th, 2006."""
However, it should be noted that the file src/pulsecore/g711.c is public
domain with the following disclaimer:
