 aRts is a short form for "analog realtime synthesizer". aRts is highly
 modular, creating and processing sound using small modules performing
 specific tasks. These may create a waveform (oscillators), play samples,
 filter data, add signals, perform effects like delay/flanger/chorus, or
 output the data to the soundcard.
 .
 This package contains the aRts sound system, its libraries and binaries,
 including the aRts daemon, artsd.
 .
 The 'akode' package adds several plug-ins to arts that can dramatically
 improve performance and help maintain uninterrupted playback. Its use
 with aRts is recommended.
 .
 This package is part of KDE, and a component of the KDE aRts module.
 See the 'kde' and 'arts' packages for more information.
