Subject: [PATCH] Relative paths in playlists
From: Brian King (brking_at_charter.net)
Date: 2002-08-01


I made a stab at adding support for relative paths in playlists. It
seems to work well on my Jukebox20. Let me know if I overlooked
something or if there is a better way to implement this.

It should handle playlists that contain entries like

./The_London_Howlin_Wolf_Sessions/02-I_Aint_Superstitious.mp3

and

../../Sonic_Youth/A_Thousand_Leaves/02-Sunday.mp3

not sure if there are any other types I should worry about...

The patch is made against the current cvs.
