+.SH SENDING DATA FROM A FILE
+If the string to send starts with an at sign (@), the rest of the
+string is taken to be the name of a file to read to get the string to
+send.  If the last character of the data read is a newline, it is
+removed.  The file can be a named pipe (or fifo) instead of a regular
+file.  This provides a way for \fBchat\fR to communicate with another
+program, for example, a program to prompt the user and receive a
+password typed in.
