### ABOUT ###
#############
# This is a simple script that downloads webaom.jnlp from static.anidb.net and runs the
# client locally. Since the script always downloads the webaom.jnlp file each time it
# is run, it will make sure you are running the latest version of the java client (even
# though it hasn't been updated in ages).
#
# Information about the AniDB WebAOM (Anime-O-Matic) can be found at:
