# NOTE - this is the updated version of this script which uses multi-threaded reload code
#
# This script uses the dataSnapshot and SchemaGenerator (via GenTester) java classes to restore
# data to a database by doing three things:
# 1) clear out whatever data and schema are currently in the db
# 2) rebuild the schema (using the SchemaGenerator)
# 3) reload data from the passed-in datafile (which must found in the dataSnapShots directory and
# contain an xml view of the db data).
