       This program

	       allows a user to create a table of cell sizes, showing how many
	      square feet, acres, and hectares each cell would represent.

	      allows  a  user  to create a table of acreage sizes, showing how
	      many square feet, hectares, and what cell size would  be	repre-
	      sented.
