# This script assumes a cdrdao TOC file with CD-TEXT in it named cd.toc
# It also assumes the front cover art is called cover.jpg
# It assumes track{TRACKNUMBER}.cdda.wav files (as generated by cdparanoia)
# The WAV files are encoded to FLAC with the TITLE, ARTIST, ALBUM, TRACKNUMBER, and ISRC set
# based on the CD-TEXT and ISRCs found on disc, and with front cover art set.
