-#!/bin/bash
-#
-# lib/dlm
-#
-# Functions to control the installation and configuration of software
-# that provides a dlm (and possibly other functions). The default is
-# **zookeeper**, and is going to be the only backend supported in the
-# devstack tree.
-
-# Dependencies:
-#
-# - ``functions`` file
-
-# ``stack.sh`` calls the entry points in this order:
-#
-# - is_dlm_enabled
-# - install_dlm
-# - configure_dlm
-# - cleanup_dlm
-
-# Save trace setting
-_XTRACE_DLM=$(set +o | grep xtrace)
-set +o xtrace
-
-
-# Defaults
-# --------
-
-# <define global variables here that belong to this project>
-
-# Set up default directories
-ZOOKEEPER_DATA_DIR=$DEST/data/zookeeper
-ZOOKEEPER_CONF_DIR=/etc/zookeeper
-
-
-# Entry Points
-# ------------
-#
-# NOTE(sdague): it is expected that when someone wants to implement
-# another one of these out of tree, they'll implement the following
-# functions:
-#
-# - dlm_backend
-# - install_dlm
-# - configure_dlm
-# - cleanup_dlm
-
-# This should be declared in the settings file of any plugin or
-# service that needs to have a dlm in their environment.
