+ *     Creates a width table for troff from a versatec font for a
+ *             normal font.
+ *     Usage: width font point_size
+ *             where font is the file name of the versatec font and
+ *             point_size is it point size.
+ *     It is better to use as large a point size font as possible 
+ *     to avoid round off.
