# Administer CUPS at http://box:631
# Above URL does NOT work over OpenVPN (ANYONE KNOW WHY?)

# TO DO:
# - validate input vars + prereqs
# - move ~7 top stanzas into install.yml
# - move ~7 next stanzas into enable-or-disable.yml
#   - create /etc/nginx/conf.d/cups-nginx.conf as SHIM to Apache on port 8090 ?
#   - deprecate ~2 F18 stanzas?
