+# Sends notification with album cover art using mpc, ffmpeg, notify-send,
+# and my other script, notify-replace.
+# For notification on song change:
+# 	Assign execute_on_song_change to this script in ncmpcpp's config file.
+# For notification on media keys:
+# 	Bind media key to a call to mpc with the approprite command.
