# this script can be used to quickly set up a new  GovReady-Q instance
# for local testing, from a freshly-cloned repository.

# Usage:
#	$ ./install-govready-q.sh
#   $ ./install-govready-q.sh --non-interactive

# note that this script DOES NOT install libraries from a package manager,
# and does not edit /etc/hosts. those will have to be done manually

# Defaults

# default is yes, run interactively
NONINTERACTIVE=
