+ <listitem><para>Specifies the default priority level for
+ messages from the process's standard error output (stderr).
+ Usage of this option is the same as the
+ <option>--priority=</option> option, above, and both can be
+ used at once. When both are used, <option>--priority=</option>
+ will specify the default priority for standard output (stdout).
+ </para>
+
+ <para>If <option>--stderr-priority=</option> is not specified,
+ messages from stderr will still be logged, with the same
+ default priority level as stdout.</para>
+
+ <para>Also, note that when stdout and stderr use the same
+ default priority, the messages will be strictly ordered,
+ because one channel is used for both. When the default priority
+ differs, two channels are used, and so stdout messages will not
+ be strictly ordered with respect to stderr messages - though
+ they will tend to be approximately ordered.</para></listitem>
