Change icon theme for GTK2

[hop-frog]

I am trying to install Nuvola icons system-wide on my desktop.

I have the icons placed in folders such like so:
/usr/share/icons/Nuvola/scalable/apps/
/usr/share/icons/Nuvola/scalable/devices/
/usr/share/icons/Nuvola/scalable/emblems/
/usr/share/icons/Nuvola/scalable/filesystems/
/usr/share/icons/Nuvola/scalable/mimetypes/
/usr/share/icons/Nuvola/scalable/stock/

I do not have GNOME installed or any of the configuration tools and installing these is not an option on this system. I have been using ~/.gtkrc-2.0 to switch GTK2 themes, but do not know how to change icon themes.

Is there a line to add to ~/.gtkrc-2.0 to change to this theme?

Thanks.

if you mean the icon theme for the buttons in the apps, it's part of the gtk theme.

the gtkrc for the theme with eithe rhave a bunch of icons listed out in it or a lie like this:
include "iconrc"

and then the iconrc would look (partially) like this:

pixmap_path "/usr/share/icons/Nuvola/scalable/stock"
style "icon-style"
{
# stock["gnome-stock-about"] = {{ "star-button.svg" }}
stock["gnome-stock-volume"] = {{ "stock-volume.svg" }}
# stock["gnome-stock-mic"] = {{ "stock_mic.svg" }}
# stock["gnome-stock-line-in"] = {{ "stock_line-in.svg" }}
# stock["gnome-stock-attach"] = {{ "stock_attach.svg" }}

..................

# stock["gnome-stock-book-blue"] = {{ "stock_book.svg" }}
# stock["gnome-stock-book-green"] = {{ "stock_book.svg" }}
}
class "GtkWidget" style "icon-style"

Incidentally, you can also just include that in your ~/.gtk2-rc I think. But the trouble with that is that gnome and xfce manage things all on their own (pretty annoying IMO).
The defaults have to be stored somewhere though :).

So, I have an icon theme for GNOME with hundreds of icons (which I downloaded here (http://librsvg.sourceforge.net/theme.php)) and I have to type of a out huge file just to use it?

actually, if you don't use gnome, and you use kde, I will just use gtk-qt engine, although it might not be gtk2 or gtk, whatever it uses. At least it works in most programs like gaim.
