# lib/keystone
# Functions to control the configuration and operation of **Keystone**

# Dependencies:
# ``functions`` file
# ``BASE_SQL_CONN``
# ``SERVICE_HOST``
# ``SERVICE_TOKEN``
# ``S3_SERVICE_PORT`` (template backend only)


# ``stack.sh`` calls the entry points in this order:
#
# install_keystone
# configure_keystone
# init_keystone
# start_keystone
# stop_keystone
# cleanup_keystone

# Print the commands being run so that we can see the command that triggers
# an error.  It is also useful for following along as the install occurs.
