# This program is a stop-gap until the deployment-wide management of
# the ACME service is implemented. So we will eventually have API
# calls for managing the ACME service, e.g. `ipa acme-enable'.
# After that is implemented, we can either deprecate and eventually
# remove this program, or make it a wrapper for the API commands.
