How to remove an GW installation from a host

Hi,

for test purpose I have set up a simple GW-System. If I want to remove
this to do a new attempt, which directorys I have to remove?

Only the dirs which I have named during the configuration?

/groupwise/<Domain-Dir> and
/groupwise/<POA-Dir> and

/etc/opt/novell/groupwise/gwha.conf ?
