Having learned C/C++ in a highschool class and Java/perl through a college class, with much self-teaching on all accounts, I like tutorials like this; that give a very basic idea of a perl script that one can build on. These types of tutorials are very helpful for those who are not programmers by nature or trade, and merely wish, or are forced, to learn a new skill.
I would like to point out two things: a direct link to the llama book would be nice and a link to woolfy's Where and how to start learning Perl (which is basically a thread of Additional Resources)
