Unity Configuration

[Peter Hillier-Brook]

OK I give up! Can anyone point me to where Unity stores its 
configuration details, specifically the Launcher and its icons. I need 
to change the text and default icon for several applications.

When Unity first started after a system upgrade it imported all the 
details from the panel and this still seems to be a viable mechanism, 
but direct editing in a terminal would be preferable.
