A slightly modified version


LL=`grep :kde.*4.*:on: /var/state/sorcery/depends|cut -d:  -f1|sort|uniq`
for S4 in $LL;do
  SS=${S4//4}
  if [ $S4 != $SS ];then
    up_trigger $S4 dispel_self
  fi
  up_trigger $SS cast_self
done


I used this to rebuild a lot of stuff on my system. The main problem was 
ensuring that all references to the old spell names were changed.

I would be in favour of removing all the kde3 stuff completely. Give a prompt 
for the first update, so that the user can refuse the updates in order to 
keep 
kde3.  Likewise for qt4/3.
