-       If empty, or not given, use stdout.
+       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
+       output to be written in a different way:
+
+       \"path\" may be prepended by '>' which instructs adu to truncate
+       the output file to length zero. If \"path\" does not start with
+       '>' and \"path\" already exists, the query is aborted. Otherwise,
+       the file is created and truncated. The output file name \">\" is
+       considered invalid.
+
+       If the first two characters of \"path\" are '>', the output file
+       (given by removing the leading \">>\" from \"path\") is opened in
+       append mode. It is no error if the output file does not exist. However,
+       as above the output file name \">>\" is considered invalid.
+
+       If the first character of \"path\" is '|', a pipe is created and the
+       rest of \"path\" is executed with stdin redirected to the reading
+       end of the pipe while the query output is written to the writing end
+       of the pipe. Again, specifying only \"|\" is considered invalid and
+       causes an error.
+
+       See the manual page for examples.
