This is an audioplayer control plugin (based on the former xfce4-xmms-plugin) if you havent figured that out yet.

Old notice for XMMS: It uses gtk, glib, xfce4-panel headers, and xmms headers.  You must have XMMS installed to compile 
this program. You'll also need the program xmms-config in your path, else it won't compile right.  99.9% of the time if 
you have XMMS installed, it is in your path and you have nothing to fear.

In the new version of course you need support for the players you've enabled.
