# Convert the 'icon' metadata column in the portal catalog to a 'getIcon'
# column. Unfortunately this means we have to drop the 'icon' column, and add
# the 'getIcon' column, then do a full reindex.
#
# To use this script, create it inside the Portal Root Folder and run it.
# You will need the Manager Role to fully assure correct execution.
