     lonManage  --reinit=lond host
-          Requests the remote system's lond perform the same action as if
-          it had received a HUP signal.
+       Causes lond in the remote system to reread the hosts.tab file
+       and adjust the set of servers to match changes in that file.
 
     In the above syntax, the host above is the hosts.tab name of a host,
     not the IP address of the host.
