Script to (partially) convert TOPAS parameter files from v2.0 to v3.0

topas2to3

#!/bin/sh

# This script will (partially) convert TOPAS parameter files from v2.0 to v3.0.
# A backup of the original file is created with a .bak extension.
# WARNING: using this script twice on the same file will delete the backup file.
