# adds three functions to your Bash terminal:
# flac2mp3 DIRECTORY - converts a directory with .flac files to .mp3 format
# itunesadd DIRECTORY - moves MP3 files to iTunes "Add Automatically" folder
# flac2itunes DIRECTORY - converts files to mp3 and adds them to iTunes in one step
#
# options can be modified below
# requires flac2mp3.pl from https://github.com/robinbowes/flac2mp3
