“This is one of those books that make me wish I had a time machine, so I could go back and give it to my past self. I think back to the hours and hours I spent gritting my teeth and picking through all sorts of documentation, whimper- ing, 'Why will nobody tell me just the basics of this stuff, nicely and clearly? Surely if I had a basic understanding and maybe an example, I could beat this to death with a Perl program smoothly and elegantly,' and I hope that the next person stuck in this situation has a copy of this book.”
