# Simple script to read metadata from mpris compatible mediaplayers via dbus.
#
# Run it like this:
# mpris amarok
#
# The script fills all fields exported by the player's dbusinterface.
# They are defined here: http://wiki.xmms2.xmms.se/wiki/MPRIS_Metadata
#
# To see which fields are actually available from your player,
# call something like this from a terminal:
#
# qdbus org.mpris.amarok /Player GetMetadata
# or
# qdbus org.mpris.vlc /Player GetMetadata
# etc.
# 
# Every field is available in the data hash 'd' via
# $d{"NAME_OF_FIELD"}
# To edit the output just change the marked line accordingly.
