Pressure canning: convert from 16oz jars to 4oz jars?

Friend of mine is canning some low-acid veg from raw, and the recipe she has recommends, let's say 20 minutes in the pressure canner for 16oz jars, and 25 minutes for quart jars. She wants to can this stuff in 4oz jars. The recipe relies on cooking time in the pressure canner, so presumably overcooking it would be Bad Somehow. What's the algorithm she would use to find out how long to pressure can 4oz jars?
