 # ``stack.sh`` is an opinionated OpenStack developer installation.  It

 # installs and configures various combinations of **Ceilometer**, **Cinder**,
 # **Glance**, **Heat**, **Horizon**, **Keystone**, **Nova**, **Quantum**
 # and **Swift**

 # This script allows you to specify configuration options of what git

 # repositories to use, enabled services, network configuration and various
 # passwords.  If you are crafty you can run the script on multiple nodes using
 # shared settings for common resources (mysql, rabbitmq) and build a multi-node
 # developer install.

 # To keep this script simple we assume you are running on a recent **Ubuntu**

 # (12.04 Precise or newer) or **Fedora** (F16 or newer) machine.  It

 # should work in a VM or physical server.  Additionally we put the list of
 # ``apt`` and ``rpm`` dependencies and other configuration files in this repo.

 # Learn more and get the most recent version at http://devstack.org

 # Global Settings
 # ===============

 # ``stack.sh`` is customizable through setting environment variables.  If you
 # want to override a setting you can set and export it::

 #

 #     export DATABASE_PASSWORD=anothersecret

 #     ./stack.sh
 #

 # You can also pass options on a single line ``DATABASE_PASSWORD=simple ./stack.sh``

 #

 # Additionally, you can put any local variables into a ``localrc`` file::

 #

 #     DATABASE_PASSWORD=anothersecret
 #     DATABASE_USER=hellaroot

 #
 # We try to have sensible defaults, so you should be able to run ``./stack.sh``

 # in most cases.  ``localrc`` is not distributed with DevStack and will never
 # be overwritten by a DevStack update.

 #

 # DevStack distributes ``stackrc`` which contains locations for the OpenStack

 # repositories, branches to configure, and other configuration defaults.
 # ``stackrc`` sources ``localrc`` to allow you to safely override those settings.
