	      use STYLE for numbering footer lines

       -h, --header-numbering=STYLE
	      use STYLE for numbering header lines

       -i, --page-increment=NUMBER
	      line number increment at each line

       -l, --join-blank-lines=NUMBER
	      group of NUMBER empty lines counted as one

       -n, --number-format=FORMAT
