Usage: "${0} [options] files" where "options" are:
 -12	=> 12-pitch (effective only with DASI terminals)
 -e	=> neqn
 -t	=> tbl
 -c	=> col
 -D     => "debug" option; ${0}'s nroff command string to standard error.
 -E	=> "-e" option of NROFF (not effective with "-c")
 -Tterm	=> where term is the desired terminal type, e.g., -Thp.  (Cat
	   /usr/pub/terminals for a list of available terminal types.)
	   If no -T option is given then \$TERM is used if it has a value
	   otherwise the default is DASI 450.
 -	=> instead of "files" inside a pipeline.
Other options as required by nroff and/or ${0}.
