+       This option is only useful in interactive mode. If stdin is redirected
+       from a script, and the script contains several queries one can use
+       this option to let each query write its output to a different file.
+
+       If the option is not given, or its argument is either \"-\" or the
+       empty string, stdout is assumed. The following conventions cause the
