MARC::Record and Net::Z3950

Ed writes: "Chris Biemesderfer recently contributed an appendix to the
MARC::Record::Tutorial [1] which shows how to use MARC::Record with Net::Z3950. His brief example is a command line program that accepts ISBNs on the command line, which then retrieves MARC records from LC, and pretty prints the MARC records on STDOUT. Chris is using Net::Z3950 and MARC::Record as part of a larger project for the Chicago Digital Distribution Center's [2] BiblioVault [3] project."
