Where are panel launchers located?

Question

I am moving from Ubuntu 8.04 to 10.4 (yeah... :)) and I would like to copy quite a few useful launchers I created over the years.

Where are they located in 8.04?

Answer 1

OK, after some snooping I think that I found the answer (a hidden directory):

$HOME/.gnome2/panel2.d/default/launchers

Update: The above path was only half of the answer. Thanks to @DoR's reply here, it seems that panel launchers also need to register at:

$HOME/.gconf/apps/panel/objects/
