.Pp
If no
.Ar file
argument is present, the standard input is read.
An argument consisting of a single minus
.Pq Fl
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:
.Bl -tag -width indent

Print only pages whose page numbers appear in the comma-separated
.Ar list
of numbers and ranges.
A range
.Ar N\-M
means pages
.Ar N
through
.Ar M ;
an initial
.Ar \-N
means from the beginning to page
.Ar N ;
and a final
.Ar N\-
means from
.Ar N
to the end.
.It Fl n Ar N
Number first generated page
.Ar N .
.It Fl s Ar N
Stop every

.Nm Troff
will stop the phototypesetter every

and resume when the typesetter's start button is pressed.

.It Fl F Ar fontdir

.Pp
If the file
.Pa /var/account/tracct
is writable,
.Nm troff
keeps phototypesetter accounting records there.
The integrity of that file may be secured by making

a  'set user-id' program.
