# Print Router Label
# This script retrieves values from the OpenWrt to print a
# concise label that contains important config info.
# This label can be taped to the side of the router
# so the next person to encounter the router (which may be
# you) can access it. It is secure because if someone
# can read the label, they can factory-reset the router anyway.
# Usage: sh print-router-label.sh [root-password] [WifiSSID] [WifiPassword]
# There's no way to determine the root password (it's hashed)
# so the script leaves it as "?" unless you supply it.
