.SH DESCRIPTION
.I Ul
replaces backspaced, overstruck underscores by control sequences suitable
for the terminal given by the environment variable
TERM or by option
.BR \-t .
It reads from the standard input or the named files and
writes on the standard output.
Option
.B \-i
represents underlining by a separate line of `\-' characters.
.PP
.I Hp
is a filter that presents most
.IR nroff
output sensibly on HP 2600 series terminals.
Option
.B \-s
stops and waits for a newline at the beginning of each page.
Option
.B \-e
uses `display enhancement' features to distinguish
underlines, superscripts, and subscripts,
which are normally all shown in inverse video.
Option
.B \-m
squeezes multiple newlines out of the output.

.SH BUGS
.I Hp
does not reliably handle reverse line feeds as produced
by

pipe the input through
.I col
to get rid of them; see
.IR column (1).
