[Haskell] Alex question

Hi, I've read through the documentation on Alex abit, but since I'm not the sharpest tool in the shed I'm not really seeing the obvious way to take the output file of Alex and make a program that will print out the list of tokens scanned from an input file. I had to do something like this this past week for a class, but that was in Java so I wanted to try it in Haskell as well but I'm stuck at the moment.
