NAME		nroff  --  format text
.ti 0
SYNOPSIS	nroff_____ [+_N] [-s__] [-h__] [-q__] [-i__] files
.ti 0
DESCRIPTION	nroff_____
formats text according to control lines embedded
in the text files.
The non-file option arguments are interpreted as follows:

.in +6
.ti -3
+N Output will commence at the first page whose page
number is N (independent of whether or not the
page number is being printed).

.ti -3
-s Stop between pages. Printing will halt prior to
each page (including the first) to permit paper
loading and changing. Printing is restarted by
typing either a "newline" or "delete" character.

.ti -3
-h High-speed output. During output, strings of
space characters are replaced where possible with
tab characters to speed up output. Futhermore, if
the output is directed into a file or a pipe,
this mode effectively reduces the total number of
characters in the file or pipe; this is especially
important in multi-column output where the
temporary file(s) or pipe(s) would otherwise contain
a large number of space characters.

.ti -3
-q The prompt names for insertions are not printed
and the bell character is sent instead; in
addition, the insertion is not echoed. This mode
permits insertions during the actual output printing

.ti -3
-i Index mode. NROFF creates a file called "index"
containing every word output together with the
line and page number. The format is word, tab,
page, tab, line, newline, etc. Invoking this mode
slows down the execution of NROFF considerably.
