# A bash script to convert all Rivendell's audio-library to MP3, extract meta-tags from Rivendell's
# database and set appropriate tags to each MP3 file.

# Notes:
# 1 - Rivendell store files in .wav format, airtime uses .mp3 format
# 2 - WAV does not have Meta-tag support so all meta-tags need to be fetched from Rivendell database.
