# NOTE: If the atlas mount was on beach.mbari.org at /mbari/LRAUV and writable 
# by tethysadmin, the rsync could be performed locally (and probably faster).

# This script _assumes_ that public key authentication has been configured with
# no password for the hotspot repository, and that ~/.ssh/config has a host 
# entry for the hotspot repository specifying the correct user and identity 
# file. That host entry may also provide a host shortcut, e.g., `ssh beach` may 
# log in to tethysadmin@beach.shore.mbari.org
