Sweep Cut?

I have a very simple part.  It is a rectangle with a cut I drew on the back left side (when you look at the sketch it will be on your right, but it is the back left of the part.)  I want this cut to sweep around both sides and the front.  I just can figure out how to do it.  Any takers? It surley will be easy for you experiences people.SolidworksParts And Features
