Any text argument t may be zero to six words. Quotes may be used to include blanks in a 'word'. Text can be empty, but unlike normal \s-2UNIX\s+2 macros, the next line is not used.

A prevailing indent distance is remembered between successive indented paragraphs, and is reset to default value upon reaching a non-indented paragraph (i.e. at .SH or .SS).

.SH SYNOPSIS
.B demo
.RI [ options ]
.IR file " ..."
.SH DESCRIPTION
This is a test for showing how to use the
.BR nroff (1)
man package. It shows how to use .TH, .SH, .PP, .B, .I, and .IP
commands.
.PP
This will be a new paragraph. You can also use normal
.BR nroff (1)
commands in the text.
.SS Nroff Commands
.IP '\ee"'
This is the comment command. \e" You won't see this.
.IP nf
No fill mode (the normal mode is fill mode where things
get justified right and left).
.IP fi
Re-enter fill mode.
.IP br
Break line here no matter what.
.IP sp
Vertical space (also causes a break to occur).
.sp
Note that to continue an indent and make a new paragraph (as
is the case here), just put in a space (.sp).
.PP
Now we should be at a new paragraph.

Executing nroff -man demo.man results in the following output: (Ignoring page headers and footers)

 .TH TITLE [1-8]

 which serves as the title of the manual page. This is
 followed by the number of the section in which it

 [ ] An argument, when surrounded by brackets is
 optional.

 exclusive. You can supply only item from
 such a list.

 ... Arguments followed by an elipsis can be
 repeated. When an elipsis follows a brack-
 eted set, the expression within the brackets
 can be repeated.

 directive, is shown first, followed by the func-
 tion declaration. Otherwise, the function declara-
 tion is shown.
