# Module: ft991utility.py
#
# Description: A utility for backing up Yaesu FT991 memory and menu settings,
# and also for restoring memory and menu settings from
# a file. Can be used both interactively or with command line
# arguments. Before running this utility, be sure to copy
# the file 'ft911.py' to the same folder as this utility.
