Mirroring content found on Perlmonks and Chris's site, Robert Nagler has made his book "Extreme Perl" available online.

As you might guess by the title, his book is about Extreme Programming using Perl. It will ultimatly be published by O'Reilly.

I've gone through some of it, it looks good. I don't really care for reading that much material online, so I printed it out for perusal at home.
