The reason the STDIN/STDOUT unix filter paradigm wasn't
implemented in this script has more to do with its original
development than with with its final functionality. The
first script was written on a Mac and I haven't found a good
way to deal with STDOUT using MacPerl. Although it did make for some
easily-implemented dialogue boxes :-)
