Changes for Net::Z3950 module, version 0.42

Changes between versions 0.41 and 0.42 (Wed Mar 31 13:06:09 2004):

• Add support for Unix-domain sockets: use unix as the hostname, and the path to the socket file as the port, in the connection constructor. Like this:

  	$conn = new Net::Z3950::Connection("unix", "/tmp/socket");
