Mpg123 is a fast and portable mpeg audio player for unix. it supports mpeg 1.0/2.0 layers 1, 2 and 3 (those famous "mp3" files).

for full cd quality playback (44 khz, 16 bit, stereo) a pentium, sparcstation10, dec alpha or similar cpu is required. mono and/or reduced quality playback (22 khz or 11 khz) is even possible on 486 cpus.

an mpg123 optimised for the 3dnow! command set nowadays is part of the main package mpg123. this is an empty dummy package to facilitate upgrades and can be safely removed.
