+# Parts of this section are required if enabling the 'consent' resource under
+# 'listeners', in particular 'template_dir' and 'version'.
+#
+# 'template_dir' gives the location of the templates for the HTML forms.
+# This directory should contain one subdirectory per language (eg, 'en', 'fr'),
+# and each language directory should contain the policy document (named as
+# '<version>.html') and a success page (success.html).
+#
+# 'version' specifies the 'current' version of the policy document. It defines
+# the version to be served by the consent resource if there is no 'v'
+# parameter.
+#
+# 'server_notice_content', if enabled, will send a user a "Server Notice"
+# asking them to consent to the privacy policy. The 'server_notices' section
+# must also be configured for this to work. Notices will *not* be sent to
+# guest users unless 'send_server_notice_to_guests' is set to true.
+#
+# 'block_events_error', if set, will block any attempts to send events
+# until the user consents to the privacy policy. The value of the setting is
+# used as the text of the error.
+#
+# 'require_at_registration', if enabled, will add a step to the registration
+# process, similar to how captcha works. Users will be required to accept the
+# policy before their account is created.
+#
+# 'policy_name' is the display name of the policy users will see when registering
+# for an account. Has no effect unless `require_at_registration` is enabled.
+# Defaults to "Privacy Policy".
+#
