I don't see anything with a '->'. I'm getting the impression that you have no
programming experience. If, as you say, you understood lines five and six then
I think you already have a grasp of what '=>' means. It tells the left hand
side of '=>' to use the right hand side values.

To recrusively search down into a directory and all or some of its
subdirectories.
