.TH MAN 6

.SH NAME

man \- macros to typeset manual

.SH SYNOPSIS

.B nroff  -man

.I file ...

.PP

.B troff  -man

.I file ...

.SH DESCRIPTION

These macros are used to format pages of this manual.

.PP

Except in

.L .LR

and

.L .RL

requests, any text argument denoted

.I t

in the request summary may be zero to six words.

Quotes

\fL"\fP ... \fL"\fP

may be used to include blanks in a `word'.

If

.I t

is empty,

the special treatment is applied to

the next text input line (the next line that doesn't begin with dot).

In this way, for example,

.B .I

may be used to italicize a line of more than 6 words, or

.B .SM

followed by

.B .B

to make small letters in `bold' font.

.PP

A prevailing indent distance is remembered between

successive indented paragraphs,

and is reset to default value upon reaching a non-indented paragraph.

Default units for indents

.I i

are ens.

.PP

The fonts are

.TP

.B R

roman, the main font, preferred for diagnostics

.PD 0

.TP

.B I

italic, preferred for parameters, short names of commands,

names of manual pages,

and naked function names

.TP

.L B

`bold', actually the constant width font,

preferred for examples, file names, declarations, keywords, names of

.B struct

members, and literals

(numbers are rarely literals)

.TP

.B L

also the constant width font.

In

.I troff

.BR L = B ;

in

.I nroff

arguments of the macros

.BR .L ,

.BR .LR ,

and

.B .RL

are printed in quotes;

preferred only where quotes really help (e.g. lower-case literals and

punctuation).

.PD

.LP

Type font and size are reset to default values

before each paragraph, and after processing

font- or size-setting macros.

.PP

The

.B -man

macros admit equations and tables in the style of

.IR eqn (1)

and

.IR tbl (1),

but do not support arguments on

.B .EQ

and

.B .TS

macros.

.PP

These strings are predefined by

.BR -man :

.TP

.B \e*R

.if t `\*R', `(Reg)' in

.if t .IR nroff .

.if n `(Reg)', trademark symbol in

.if n .IR troff .

.br

.ns

.TP

.B \e*S

Change to default type size.

.SH BUGS

There's no way to fool

.I troff

into handling literal double quote marks

.B \&"

in font-alternation macros, such as

.LR .BI .

.br

There is no direct way to suppress column widows in 2-column

output; the column lengths may be adjusted by inserting

.L .sp

requests before the closing

.LR .1C .
