- * ossaudiodev -- Python interface to the OSS (Open Sound System) API.
- *                This is the standard audio API for Linux and some
- *                flavours of BSD [XXX which ones?]; it is also available
- *                for a wide range of commercial Unices.
- *
- * Originally written by Peter Bosch, March 2000, as linuxaudiodev.
- *
- * Renamed to ossaudiodev and rearranged/revised/hacked up
- * by Greg Ward <gward@python.net>, November 2002.
- * Mixer interface by Nicholas FitzRoy-Dale <wzdd@lardcave.net>, Dec 2002.
