Focus stacking

"The usual way around this is to focus stack, merge several shots taken at different focus points. But if the G9 doesn’t have a manual focus mechanism, that stays put from shot to shot, then this will be difficult."

I would be interested to know how you'd go about focus stacking, merging, etc., assuming one can do this with an SLR.
