Changes for Net::Z3950 module, version 0.43

Changes between versions 0.42 and 0.43 (Thu May 6 14:19:56 2004):

• Add support for Scan, using code contributed by Jan Bauer Nielsen <jbn@dtv.dk>, somewhat tidied up. Use it like this:

  $apdu = $conn->scan('@attr 1=1003 kern');
  $status = $apdu->scanStatus();
  if ($status == 6) print Dumper($apdu->diag());
  $count = $apdu->numberOfEntriesReturned();
  $term = $apdu->entries()->[0]->termInfo()->term()->general();
  $hits = $apdu->entries()->[0]->termInfo()->globalOccurrences();
  	

  Subsequent releases will support more corners of the Scan specification (e.g. displayTerm and friends), and present a much nicer API with a ZOOM-like ScanSet object. See zoom.z3950.org/api/zoom-1.4.html#3.6

• Included in the samples directory is a simple scanning client program, scan.pl.
