# This script copies the minecraft world folder to the map folder once a week, on Monday.
# Use the start.sh script to launch the backup process, as start.sh calls this script in a new screen.
# Every new folder copied over overwrites the latest world copy.
# The weekly backed up folder may be found publicly at https://github.com/MiddCraft/map
