.SH DESCRIPTION
.I troff

for
printing on a phototypesetter;
.I nroff
for typewriter-like devices.
Their capabilities are described in the
.I Nroff/Troff user's manual.
.PP
If no
.I file
argument is present, the standard input is read.
An argument consisting of a single minus
.RB ( \- )
is taken to be
a file name corresponding to the standard input.
The options, which may appear in any order so long as they appear
before the files, are:
.TP "\w'\f3\-m\f1name 'u"
.BI \-o list
Print only pages whose page numbers appear in
the comma-separated
.I list

A range
.IB N \- M
means pages
.I N
through
.IR M ;
an initial
.I \-N
means
from the beginning to page
.IR N ;
and a final
.IR N \-
means
from
.I N
to the end.
.TP
.BI \-n N
Number first generated page
.IR N .
.TP
.BI \-m name

.BI /usr/lib/tmac/tmac. name

.IR N .
.TP

.br
.bd I
.TP
.B \-a

If the file

is writable,
.I troff
writes phototypesetter accounting records there.
The integrity of that file may be secured by making
.I troff
a `set user-id' program.
