xspf_player questions

[nomadsoul]

I'm using the kplaylist script along with the xspf_player and they are wonderful programs but there is precious little information and support for them. 

Here is a page that describes some of the customizing options: http://www.xspf-player.com/options.html

but they don't explain how to apply this file to the player.  For example, do I make a separate file and link it to the player's .as file?  If so, how?  do I make an .xspf file? or php?

In essence, they tell you how to tweak the parameters but they don't tell you how to use the file in relation to the player.
