# Script to setup a host for running in Home Swarming CI.
#
# Prereqs:
#   this script and its dependencies are scp'd to the swarm lab host via:
#     $ scp /google/data/ro/teams/cast-test/swarming/* gtvchrome@<lab-host-ip>:/home/gtvchrome/
#        (gtvchrome password in valentine)
#   all of these shell scripts have chmod +x on the lab host:  chmod +x *.sh
#   you're ssh'd into the lab host and ready to run this script on it
#
# Usage:
#  ./setup_swarm_host.sh

# stop any bots that might be running already
