+ 6. There is a new ACL control called "debug", to enable debug logging.
+    This allows selective logging of certain incoming transactions within
+    production environments, with some care.  It takes two options, "tag"

+    is used as per the -d<options> command-line option.  Examples, which
+    don't all make sense in all contexts:

+      control = debug/opts=+expand+acl
