Good. 
And with combination with PREPARE code:

if [[ $(installed_version $SPELL| cut -d. -f1) == 3 ]]; then
 query "You are about to cast ${SPELL_COLOR}$SPELL${QUERY_COLOR} from branch 
KDE 4. Do you want to procede?" n
fi


That makes possible that users on kde3 refuse to update and stay on kde3. 
From 
my point of view that is enough for protecting users from kde4 when we rename 
spells.

OK. Lets try it. I will send email to ML with my plan/timeline of kde3 
removal. And we will continue discussion there.
