-     Looked up in the usual way, but used by client to

+     We define the sets of putative clients and servers, as follows:
+     all those, for which there is any section (even an empty one)
+     whose name is based on <client> or <servername> (as applicable).
 
-     The client will create a local interface, and try to communicate
-     with the server, for Each (<servername>,<clientaddr>) pair for
-     which the config search yields a password.
+     The server queue packets for, and accept requests from, each
+     putative client for which the config search yields a password.
 
-     On the server: clients with no password are ignored.
+     Each client will create a local interface, and try to communicate
+     with the server, for each possible pair (putative server,
+     putative client) for which the config search yields a password.
