# This script is to spin up a simulation in VIRL, and fetch the URLs for all packages
# that the user would obtain if they did an "yum update" today.
#
# This entire step is neither secure nor portable. The assumption --for now-- is that
# this will only ever be run in LF CSIT VIRL lab. Should the requirement arise to
# run this elsewhere, then additional work may be required to make this more
# portable.

# This script requires that the following two environment variables be defined-
#
# $VIRL_USER
# $VIRL_PASSWORD
