# ``stack.sh`` is an opinionated OpenStack developer installation. It
# installs and configures various combinations of **Ceilometer**, **Cinder**,
# **Glance**, **Heat**, **Horizon**, **Keystone**, **Nova**, **Neutron**,
# and **Swift**
# This script's options can be changed by setting appropriate environment
# variables. You can configure things like which git repositories to use,
# services to enable, OS images to use, etc. Default values are located in the
# ``stackrc`` file. If you are crafty you can run the script on multiple nodes
# using shared settings for common resources (eg., mysql or 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** (F18 or newer) machine. (It may work
# on other platforms but support for those platforms is left to those who added
# them to DevStack.) It should work in a VM or physical server. Additionally
# we maintain a list of ``apt`` and ``rpm`` dependencies and other configuration
# files in this repo.
