# Bootstrap the Taler setup for the user account that
# is currently logged in.

# The setup generated by this script is suitable for
# blue-green deployments, where two users run
# identical environments, and traffic can be switched
# between them.

# To create a demo setup, run
# demo-blue$ ~/deployment/bootstrap-bluegreen demo
# demo-green$ ~/deployment/bootstrap-bluegreen demo

# There MUST be a user with the same name
# as the deployment basename to share data
# between the blue/green deployment.
