Angstrom remove package question

Hi All,

One more Angstrom question.
I want to try and cut back the DEMO image so I can compress it and get
it on the NAND.. I'm not sure if that is possible, hopefully it is.

Is there a way of removing packages on Angstrom that actually removes
the config files and prog files from the card?
I notice that opkg remove <package> does not actually remove all the
files/libraries from the card.

Any help would be much appreciated!

Many thanks,
