This file describes the concept behind this program. All is licensed under
GPLv2.

There are two playlists:

1) Priority playlist: initially empty

2) Default playlist: initial contents are loaded from XMMS's playlist

When a new song is about to be played, the priority playlist is checked. If
there is a song, it is dequeued off the list and played. If the playlist is
empty, nothing is done - XMMS just played another song.

One uses the 'a' and 'd' commands to append (enqueue) and delete (dequeue)
songs from the priority lists. For exact command syntax see the 'h' command
in the program.

Here's a sample run of the program:
