# Two warnings:
# 1) This script uses a script to run cjdroute and feed it
#    the config. It can be found in the main cjdns repo:
#    contrib/sh/run-cjdroute.sh
#    Or here: http://ix.io/fYT
# 2) service_respawn is disabled by default because you need
#    "noBackground":1 in cjdroute.conf for it to actually work.
#    Barely.
