My music-delivery system here is based on a collection of .ogg files 
living on the same machine that is used to play them.  Therefore, the file

	/music/Saint\ Etienne/Foxbase\ Alpha/playlist.m3u

contains entries looking like this:

	#EXTM3U
	#EXTINF:42,This is Radio Etienne
	This is Radio Etienne.ogg
	#EXTINF:269,Only love can break your heart
	Only love can break your heart.ogg
	#EXTINF:119,Wilson
	Wilson.ogg
	#EXTINF:283,Carnt sleep
	Carnt sleep.ogg

and so forth.  This playlist is built up by a shell-script that i) encodes 
the .WAV files ripped from the disk, ii) updates my MySQL database with 
filename info, and iii) builds the playlist file.

I want to move the .ogg files onto a dedicated music server.  This music 
server will then allow the music to be played from any machine on the LAN 
by serving the files over my 100 Mbit LAN.  The server will make the 
/music area available as an NFS share, but I also want to serve the .ogg 
files out using HTTP.  XMMS can use URL's instead of filenames in a 
playlist.

Notice the spaces in the filenames, which are illegal in a URL.  Some file 
names contain other characters that are also not legal in URL's.  So I 
needed to write a program to convert all existing playlists to contain 
valid encoded URLs like this:

	#EXTM3U
	#EXTINF:42,This is Radio Etienne
	http://music/Saint%20Etienne/Foxbase%20Alpha/This%20is%20Radio%20Et
	#EXTINF:269,Only love can break your heart
	http://music/Saint%20Etienne/Foxbase%20Alpha/Only%20love%20can%20br
	#EXTINF:119,Wilson
	http://music/Saint%20Etienne/Foxbase%20Alpha/Wilson.ogg
	#EXTINF:283,Carnt sleep
	http://music/Saint%20Etienne/Foxbase%20Alpha/Carnt%20sleep.ogg

(truncated on right to fit).  Here, I'm using a server (hostname "music") 
to run Apache and serve the .ogg files out of DOCUMENT_ROOT/artist/album.

The problem is the shell-script that builds the playlist in the first 
place (each time I rip a new CD).  That shell-script has the name of the 
track (like "Carnt sleep") and uses that plus ".ogg" as the output 
filename.  It then used that filename when creating the playlist.  But 
from now on, playlists are to use URLs instead of pure filenames so I need 
to encode the URL.
