# Copy a local publication bundle (from deploy-token-aggregation-for-publication.sh) to the explorer host

# Prereq:

# Usage:
#   EXPLORER_SSH=root@192.168.11.140 REMOTE_DIR=/opt/token-aggregation \

#   REMOTE_DIR     default /opt/token-aggregation
#   REMOTE_SERVICE systemd unit to restart (default: token-aggregation); empty to skip restart
#   SYNC_REMOTE_ENV set to 1 to allow bundle .env to overwrite remote .env (default: preserve remote env)
