Initialize `addrlen' before using. This might be the reason for `getnameinfo' failing..

-The server to send data to. B<This is not yet implemented!> Maybe a better name

+In B<client mode> the B<Server> statement sets the server to send datagrams to.
+The statement may occur multiple times to send each datagram to multiple
+destinations.
 
-(UDP-)Port to send packages to or to bind to and wait for packages. This option
-is available in the B<Client> and B<Server> mode.
+In B<server mode> the B<Listen> statement sets the interfaces to bind to. When
+multiple statements are found the daemon will bind to multiple interfaces.
+
+The argument I<Host> may be a hostname, an IPv4 address or an IPv6 address. If
+the argument is a multicast address the daemon will join that multicast group.
+
+If no B<Listen> statement is found the server tries join both, the IPv6
+multicast group and the IPv4 multicast group. If no B<Server> statement is
+found the client will try to send data to the IPv6 multicast group first. If
+that failes the client will try the IPv4 multicast group.
+
+The default IPv6 multicast group is C<ff18::efc0:4a42>. The default IPv4
+multicast group is C<239.192.74.66>.
+
+The optional I<Port> argument sets the port to use. It can either be given
+using a numeric port number or a service name. If the argument is omited the
+default port B<25826> is assumed.
