Links in LaTeX pdfs

My advisor gave me a somewhat criptic piece of advice that I should "add more links" to my CV. I noticed that his CV had more web addresses on it, and that when viewed in Adobe Acrobat Reader those addresses were "clickable." So I asked to see his .tex file and discovered the trick.

He uses the hyperref package by inserting this line: \usepackage[pdftex]{hyperref}. When used in combination with the url package (\usepackage{url} a hyperlink can show up in the PDF when it is done like this: \url{http://www.cs.utah.edu/~coop}
