# Script to manage renaming existing files in given directory and
# propagating that change to database. Typical usage: renaming files
# from 'title.mp3' to title - artist.mp3'
#
# Actions:
#
# - record all filenames and inode numbers
# - external: rename the files
# - update records with new filenames for each inode number
# - update external database with new paths
