.th QF VI 21/2/79
.sh NAME
qf \*- a qume filter
.sh SYNOPSIS
qf [-lnn] [-pnn] [-inn] [file...]
.sh DESCRIPTION
.it qf
is a post processor designed to optimise vertical and horizontal motion
of a qume.
It guarantees not to perform reverse carriage motions.
It is particularily useful on complicated output resulting from
.it nroff
and
.it neqn.
If
.it file
is present in the argument list these are used for input
otherwise standard input is used.
.s2
The
.bd -l
flag is used to specify a line length (defaults 72) in characters.
The
.bd -p
flag sets the horizontal pitch in characters per inch (defaults 12cpi).
The
.bd -i
flag
sets the vertical pitch in lines per inch (defaults 6lpi).
.sh BUGS
Optimisation should really be done in hardware.
