Preference pane update

[rasmusmaagaard]

Hi group,

I have made a system preference pane "app" and would like to use
update engine to allow the end user to update the pref pane. As it is
the pref pane itself which needs to be updated I don't known how write
the update script.

My problem is how do I quit system preference and copy/install the new
pref pane and restart the system preference again (and make it show
the new pref pane) from the script?

Thank you very much!
