ql-playlists – Export Quod Libet saved searches to M3U playlists. Bash script with many options.

	#!/bin/bash

	# ql-playlists
	#
	# Generate radio playlists from Quod Libet saved searches.
	# Quod Libet must be running before starting this script,

	#
	# This may not be the fastest way to do it (~250 songs/s on my system),
