+.Sh SYNOPSIS
+.Nm rwho
+.Op Fl a
+.Sh DESCRIPTION
+The
+.Nm rwho
+command produces output similar to
+.Xr who ,
+but for all machines on the local network.
+If no report has been
+received from a machine for 5 minutes then
+.Nm rwho
+assumes the machine is down, and does not report users last known
+to be logged into that machine.
+.Pp
+If a users hasn't typed to the system for a minute or more, then
+.Nm rwho
+reports this idle time. If a user hasn't typed to the system for
+an hour or more, then
+the user will be omitted from the output of
+.Nm rwho
+unless the
+.Fl a
+flag is given.

+.Sh HISTORY
+The
