changing icon theme in debian without a DE installed?

[Nick Lidakis <nlidakis@verizon.net>]

I've tried Googling this to no avail. I have the file manager Thunar 
installed. I'm trying to figure out how to change the icons that Thunar 
(or all of my GTK2 apps for that matter, e.g. Abiword) is using. It 
seems to using the the stock gnome icons I have installed. I don't have 
Gnome or Xfce installed. GTK2-theme switch is installed, but that just 
changes the GTK theme from ./themes. Apt-cache search reveals nothing 
similar to GTK2-theme-switcher.

Any ideas?
