SUMMARY = "Audio decoder for MPEG-1 Layer 1/2/3"
DESCRIPTION = "The core of mpg123 is an MPEG-1 Layer 1/2/3 decoding library, which can be used by other programs. \
mpg123 also comes with a command-line tool which can playback using ALSA, PulseAudio, OSS, and several other APIs, \
and also can write the decoded audio to WAV."
