propose_sns.sh

#!/usr/bin/env bash
#
# This takes an optional path to a configuration file; defaults to
# sns_init.yaml, in the same directory as this script. This argument gets passed
# to `sns propose`. Such a file can be constructed by following the directions
# at the top of example_sns_init.yaml.
#
# This is mostly copied from deploy_sns.sh.
#
# Besides replacing `sns deploy` with `sns propose`, the biggest differences
# here are
#
#     1. No more `ic-admin ... propose-to-update-sns-deploy-whitelist`.
#
#     2. This does not take a CONFIG argument.
