# List which files are open in mixxx
# (either being played or queued to play next)
# because for the currently playing song,
# while mixxx does show the file metadata,
# it provides no way to discover the file path/name
# or to delete the file, therefore, this yields
# the necessary file handle with which to delete
# the currently playing song.

# This is launched by user cronjob on reboot:
# @reboot	/usr/local/bin/mixxxing

# and watched by watchlogs by doing this:
# echo /var/log/mixxxing.log >> ~/.monitor.txt
# watchlogs

# and logrotate via /etc/logrotate.d/mixxxing
#	/var/log/mixxxing.log {
#		daily
#		missingok
#		rotate 32
#		compress
#		notifempty
#	}

# CONFIGURATION
library=/home/raid/audio	# where did we configure mixxx's library?
