## this is a dirty, lame hack by a dirty, lame guy 
## - reads a .m3u file (e.g. generated by xmms)
## - converts any audiofile to wavefiles using incredible mplayer 
## - provides normalized wavefiles using transcode
## - burns an audio-cd
# !!feel free to copy, modify, redistribute and at most _use_ it!!
