What Paul shows, is a good way to shape.  However, when you say 60 Mbps (of 100 Mbps), I believe most shapers don't account for L2 overhead.  So if you really want to only use 60% of your 100 Mbps, you'll need to shape 5 to 15% slower (unfortunately, L2 overhead percentages varies based on packet size - allowing for average packets sizes is usually "good enough").
