# Subscribing to an event requires you to create a new service tagged with the
# 'event_subscriber' tag. This tells the service container, and by proxy the
# event dispatcher service, that the class registered here can be queried to get
# a list of events that it would like to be notified about.
#
# For more on defining and tagging services see
# https://api.drupal.org/api/drupal/core%21core.api.php/group/container/8.2.x
services:
  # Give your service a unique name, convention is to prefix service names with
  # the name of the module that implements them.

    # \Symfony\Component\EventDispatcher\EventSubscriberInterface
