+# It creates the repository configuration file for package updates, and it
+# monitors that config to see if it has been disabled by the overly aggressive
+# distro upgrade process (e.g.  intrepid -> jaunty). When this situation is
+# detected, the respository will be re-enabled. If the respository is disabled
+# for any other reason, this won't re-enable it.
+#
+# This functionality can be controlled by creating the $DEFAULTS_FILE and
+# setting "repo_add_once" and/or "repo_reenable_on_distupgrade" to "true" or
+# "false" as desired. An empty $DEFAULTS_FILE is the same as setting both values
+# to "false".
