class neutron::deps {
  # Setup anchors for install, config and service phases of the module.  These
  # anchors allow external modules to hook the begin and end of any of these
  # phases.  Package or service management can also be replaced by ensuring the
  # package is absent or turning off service management and having the
  # replacement depend on the appropriate anchors.  When applicable, end tags
  # should be notified so that subscribers can determine if installation,
  # config or service state changed and act on that if needed.
