I hadn't even realized that site was there. And at
http://www.plkr.org/samples there's some neat samples, like Perl programming books, Wizard of Oz, and other goodies.
Even a Celiac recipe book with 55 recipes for those with a gluten intolerance. That's something that is apparently rare, yet I know at least two people with a severe case so maybe it's not quite so rare after all.
