# between them.

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

# NOTE: ENVNAME is also the name of the user who keeps
# shared data in its home directory, so it must exist!
# For demo/test ENVNAMEs, see {demo,test}.sh
