+========================================================================
+
+${SCRIPT_NAME} has detected that some packages need upgrading on:
+
+    ${FQDN}
+    [ ${IP} ]
+
+The following packages are currently pending an upgrade:
+
+$(echo "${PACKAGES}" | sed 's/^\[/    [/')
+
+========================================================================
+
+You can perform the upgrade by issuing the command:
+
+    emerge -NDuk world
+
+as root on ${FQDN}
+
+It is recommended that you pretend the upgrade first to confirm that
+the actions that would be taken are reasonable. The upgrade may be
+pretended by issuing the command:
+
+    emerge -NDuvpk world
