# My mp3s are always heniously unsorted and blowed if im gonna sit there spending hours sorting them
# Call me lazy or something but this definatly helps (even though i spent a couple days writing this and working out bugs)
#
# WARNING – THIS PROGRAM RELIES ON ID3 TAGS!
#
# There are a couple programs to get the ID3 tags sorted out available
# easytag, juk, rhythembox etc (those are all gui ones)
#
# Make sure mp3info is installed ( http://ibiblio.org/mp3info/ )
# just ./runthis and hey presto (make sure you edit where your mp3s are of course first)
#debug
#set -x

#The Dir where all your mp3s are
DIR=”/other/mp3s”

#The final destination dir for the mp3s – No trailing / needed
DESTINATION=”/other/mp3s”

#This is the thing that seperates fields (some people prefer _ some prefer a space however SPACES BREAK THINGS! use ‘1’ if you want spaces)

#try not too edit to much below this
