Install Blu-Ray AACS VUK keys for libaacs automatically from the FindVUK database.

aacsdb-update

#!/bin/bash
#
# This is a simple bash script, designed to allow
# quick download and installation of the FindVUK
# AACS VUK database.
#
# This allows Blu-Ray disks who's VUK is known
# to be played on systems using libaacs.
#
# It's reccomended to schedule this file to run
# once or twice daily, in order to keep your 
# KEYDB.cfg up-to-date.
#
# NOTE:
# This *does not* provide the files needed to
# properly decode the small number of disks that
# use BD+.

# several typos that I had missed.
