#### Database upgrade ####

This script will upgrade your VuFind database from 1.0 RC2 to 1.0.
Only minor adjustments will be made to compensate for a small bug in RC2;
there will be no structural changes.  It is still recommended that you
make a backup before proceeding with this script, just to be on the safe
side!
