+1.20 (IN PROGRESS)
+ - Add new sample program, samples/zoom/zoomscan.pl
+ - samples/zoom/zoomtst1.pl now accepts arbitrary options at
+ the end of the command-line, so that (for example) you can
+ specify a non-USMARC record syntax.
+ - The render() method of ZOOM::Exception(), and therefore the
+ overloaded stringifying operator, deals with exceptions that
+ have no message().
