# This script upgrades the IceGrid registry database environment for

# Usage:
#
# python upgradeicegrid.py olddbenv newdbenv
#
# Where for example:
#
# olddbenv is the path of the Ice 3.1.x registry database environment
# newdbenv is the path of new registry database environment
#
#
# NOTE: the 3.x slice definitions for the IceGrid database are stored
# in the icegrid-slice.3.x.tar.gz file. These definitions are used by
# the script to perform the database transformation.
