2: * Creates a width table for troff from a versatec font for a
3: * normal font.
4: * Usage: width font [ point_size ]
5: * where font is the file name of the versatec font and
6: * point_size is it point size.
7: * If the point size is omitted it is taken from the suffix of
8: * the font name, as bocklin.14 => 14 point.
9: * It is better to use as large a point size font as possible
10: * to avoid round off.
