 .SH FEED HOSTS

+.P
 It is possible to pass a list of feed hostnames on the command-line
 (see [HOSTNAMES] in the synopsis). By default \fBhtsn\fR will attempt
 to connect to every known TSN XML feed host in a round-robin fashion,
 so there is rarely a need to do this.
 
+.SH CONFIGURATION FILE
+.P
+Any of the command-line options mentioned above can be specified in a
+configuration file instead. We look for a file named \(dq.htsnrc\(dq

+htsnrc.example file (included with \fBhtsn\fR).
