In a food processor, combine the cookie crumbs, butter, and salt and process until evenly mixed. Put aside 2-3 tablespoons of the crumb mixture for the topping. Press the remaining mixture firmly and evenly against the bottom and sides of the pie pan. Bake on the center rack of the oven for 10 minutes. Allow to cool on a wire rack for about 20 minutes before adding the pie filling.
