The cabinets are screwed to the wall studs from the cabinet inside
through the nailing strip(s). However, don't lock the screws down
real tight until all are up. At that point, align the front edges of
the cabinets and hold them that way with handscrews.

An article in Fine Homebuilding suggested aligning the whole run of
cabinets on the ground and screwing them together (with spacers at the
back if they have face frames at the front). Then the whole run is
lifted up to the wall as a unit. You then shim behind them before
screwing them to the wall. That way you're guaranteed proper alignment
along the front, and the shims give proper support at the back.
