The 'juke' script is outdated. To use jukebox, I did the following:
1. Get Axel Belinfante's 'mkmap' and 'du2map' scripts from his contrib dir.
2. Copy the perl binary to my $home/bin/386
3. Run mkmap to get a map file of my music, then copy mapfile to /sys/lib/music/map
4. Create the file /bin/games/mp3dec containing the following:
	#!/bin/rc
	cat $3 | madplay -q -o RAW:- -
5. Run the following commands, conveniently stuck in the 'juke' script in contrib/john:
	games/playlistfs
	games/jukefs
	games/jukebox
6. Enjoy my music
