+Added access control facility by interfacing the TCP wrapper library.
+YAZ automatically attempts to find the TCP wrapper Library (-lwrap) and
+tcpd.h on Unix systems. For the server, option -d<daemon> specifies the
+name of the daemon and enables the access control as specified in
+hosts.allow/hosts.deny. Refer to man pages tcpd(8) and hosts_access(5).
