lpf - lpd filter for nroff output
lpf -w width -l length
lpf is a filter which reads the output of nroff and converts lines with
^H’s to overwritten lines. Thus this works like ul(1) but is much
better: it can handle more than 2 overwrites and it is written with
some style.
This program was designed long ago, and is not much if any use today.
lpf will send itself the STOP signal when it encounters the character
sequence ‘\031\1’.
