.sh DESCRIPTION
.it Troff
formats text for a Graphic Systems phototypesetter
according to control lines embedded
in the text files.
It 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:

typesetting at the first page numbered \fIn\fR or larger.

\fB\*-\fIn\fR	Stop
after page
.it n.
.s3
.lp +10 10
\fB\-s\fIn\fR	Print output
in groups of
.it n
pages,
stopping the typesetter after each group.
.s3
.lp +10 10
