35 \fB\--heart-restart=C,T\fR
36 This controls the number of restarts in a given time period that heart
37 tolerates before refusing to restart Yaws. By default, heart allows up
38 to 5 restarts within a 60 second period before refusing to restart
39 Yaws again. This option allows up to \fIC\fR restarts in \fIT\fR
40 seconds instead. To allow infinite restarts, set both \fIC\fR and
41 \fIT\fR to 0. This switch automatically enables the \fI--heart\fR
