#   Transfer the server directories and files from this host to the named
#   host. This script uses tar and ssh.
#   Play safe. Don't risk overwriting or deleting anything that already exists.
#
#   Run this as root or you will not have permission to create webserver dirs.
#
#   If you are not using key pairs with no passphrases to log in, this
#   is a pain in the arse to run. You will type in your password a dozen times.
