+DESCRIPTION
+\fITee\fR copies its input to both the standard output and the named file.
+Its primary use is in pipes where one wants to capture some intermediate output.
+.ih
+EXAMPLES
+
+1. The results of the \fIset\fR command are captured in the file "temp",
+and are also passed on to the "match" command.  The result is
+a "temp" file of perhaps 100 lines, with the output to the screen
+only around 5 lines.
+
+	cl> set | tee temp | match tty
+.ih
+BUGS
+Since the processes in an IRAF pipe execute serially rather than concurrently,
+the teed output will not appear until all tasks to the left have completed.
