.sh DESCRIPTION
.it Nroff
formats text according to control lines embedded
in the text files.
.it Nroff
reads the standard input if
no file
arguments are given.
An argument of just ``\-'' refers to the standard input.
The non-file option arguments are interpreted as follows:
.s3
.lp +10 10
\fB+\fIn\fR	Output commences at the first page whose page
number is
.it n
or larger.
.s3
.lp +10 10
\fB\*-\fIn\fR	Printing
stops after page
.it n.
.s3
.lp +10 10
\fB\-n\fIn\fR	First generated (not necessarily printed)
page is given number \fIn\fR;
simulates ``.pn|\fIn\fR''.
.s3
.lp +10 10
\fB\-r\fIan\fR	Set number
register to the value
.it n.
.s3
.lp +10 10
\fB\-m\fIname\fR	Prepends a standard macro file;
simulates ``.so /usr/lib/tmac.\fIname\fR''.
.s3
.lp +10 10
\fB\*-s\fR	Stop prior to
each page to permit paper
loading.
Printing is restarted by
typing a `newline' character.
.s3
.lp +10 10
\fB\*-h\fR	Spaces
are replaced where possible
with
tabs to speed up output (or reduce
the size of the output file).
.s3
.lp +10 10
\fB\*-q\fR	Prompt
names for insertions are not printed
and the bell character is sent instead;
the insertion is not echoed.
