# ALLTAG - MP3 retagging utility
# Copyleft 2005 - Nathan E. Pralle
#
# DESCRIPTION: 	This utility sets an MP3's ID3 tag as a derivative 
# of the file name.  It expects file names to be in the form:  
# ARTIST - SONGNAME.mp3 
# It can handle full pathnames easily as well.
# 
# SYNTAX:  ls *.mp3 | perl alltag.pl
# I prefer to work up an entire listing of all MP3 files I want 
# to retag and run them through all at once, a la:  
# find | grep \.mp3 | perl alltag.pl
#  
# REQUIRED: You must have id3ed installed on your system to do the
# actual tagging.  (Get it from freshmeat.net)
#
