# ``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**
# (11.10 Oneiric 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
# Keep track of the devstack directory

# 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 and branches to configure. ``stackrc`` sources ``localrc`` to
# allow you to safely override those settings.

# Proxy Settings
# --------------

# ``http_proxy``, ``https_proxy`` and ``no_proxy``. They can be set in

#
# [1] http://www.w3.org/Daemon/User/Proxies/ProxyClients.html
