# Replace the following variables for your environment
# zxtm - hostname of your Stingray Traffic Manager
# zxtmuser - username used to log in to Stingray SSH interface
# git_path - path to the git repo you want to store the config backups in
#
# I recommend that zxtmuser is able to log in to the Traffic Manager
# without using a password, using SSH keys.
#
# The script expectes that you have already created a git repository with
# a remote configured, as it does a git push at the end. You may want to
# change that behaviour if it doesn't suit you
