#!/bin/bash
# Script to generate the basic database for auditor
# testing from a 'correct' interaction between exchange,
# wallet and merchant.
#
# Creates $BASEDB.sql, $BASEDB.fees and $BASEDB.mpub.
# Default $BASEDB is "auditor-basedb", override via $1.
#
# Currently must be run online as it interacts with
# bank.test.taler.net; also requires the wallet CLI
# to be installed and in the path.  Furthermore, the
# user running this script must be Postgres superuser
# and be allowed to create/drop databases.
