theme variables

Hello there,

I searched the whole Xaraya site and more, but I just can't find a list 
with all the variables which can be used in the theme-templates.

I'm especially looking for a variable to change the hard-coded path to 
the theme-directory. For example, in the Xaraya-Classic theme the 
default.xt is full of <img src="themes/Xaraya_Classic/...

Sure there is a way to make this dynamic, so you have to define it only 
once (in the xartheme.php)?

Thank you,
Rolf
