note TheDamian Thanks for the errata. I've passed them on to O'Reilly. <p>Getopt::Clade will be on CPAN in August. Unfortunately, my planned release schedule had to be slipped slightly due to a series of family medical emergencies. <p>Regarding no GRT example: There were probably two dozen examples of useful-but-not-essential techniques that I had to leave out to keep the book to a "mere" 550 pages. GRT was one of those. 477093 477096
