23.Sh DESCRIPTION
24These macros are used to lay out the reference pages in this manual. Note: if
25.Ar file
26contains format input for a preprocessor, the commands shown
27above must be piped through the appropriate preprocessor. This is handled
28automatically by the
29.Xr man 1
30command. See the
31.Sx Conventions
32section.
33.Lp
34Any text argument
35.Ar t
36may be zero to six words. Quotes may be used to
37include SPACE characters in a
38.Qq word .
39If
40.Ar text
41is empty, the special
42treatment is applied to the next input line with text to be printed. In this
43way
44.Nm \&.I
45may be used to italicize a whole line, or
46.Nm \&.SB
47may be used to make small bold letters.
48.Lp
49A prevailing indent distance is remembered between successive indented
50paragraphs, and is reset to default value upon reaching a non-indented
51paragraph.  Default units for indents
52.Nm i
53are ens.
54.Lp
55Type font and size are reset to default values before each paragraph, and after
56processing font and size setting macros.

106.El
107.Ss "Conventions"
108When formatting a manual page,
109.Nm
110examines the first line to determine
111whether it requires special processing. For example a first line consisting of:
112.Lp
113.Dl \&'\e" t
114.Lp
115indicates that the manual page must be run through the
116.Xr tbl 1
117preprocessor.
118.Lp
119A typical manual page for a command or function is laid out as follows:
120.Bl -tag -width ".SH RETURN VALUES"
121.
122.It Nm \&.TH Ar title Op "1-9"
123.
124The name of the command or function, which serves as the title of the manual
125page. This is followed by the number of the section in which it appears.
126.
127.It Nm \&.SH NAME
128.
129The name, or list of names, by which the command is called, followed by a dash
130and then a one-line summary of the action performed. All in roman font, this
131section contains no
132.Xr troff 1
133commands or escapes, and no macro requests.
134It is used to generate the database used by the
135.Xr whatis 1
136command.
137.
138.It Nm \&.SH SYNOPSIS
139.Bl -tag -width "Functions:"
140.It Sy Commands:
141The syntax of the command and its arguments, as typed on the command line.
142When in boldface, a word must be typed exactly as printed.  When in italics, a
143word can be replaced with an argument that you supply. References to bold or
144italicized items are not capitalized in other sections, even when they begin a
145sentence.
146.Lp
147Syntactic symbols appear in roman face:
148.Bl -tag -width "   "
149.It Op " "
150An argument, when surrounded by brackets is optional.
151.It |
152Arguments separated by a vertical bar are exclusive. You can supply only one
153item from such a list.
154.It \&.\|.\|.
155Arguments followed by an ellipsis can be repeated. When an ellipsis follows a
156bracketed set, the expression within the brackets can be repeated.
157.El
158.It Sy Functions:
159If required, the data declaration, or
160.Li #include
161directive, is shown first,
162followed by the  function declaration. Otherwise, the function declaration is
163shown.
164.El
165.
166.It Nm \&.SH DESCRIPTION
167.
168A narrative overview of the command or function's external behavior. This
169includes how it interacts with files or data, and how it handles the standard
170input, standard output and standard error. Internals and implementation details
171are normally omitted. This section attempts to provide a succinct overview in
172answer to the question, "what does it do?"
173.Lp
174Literal text from the synopsis appears in constant width, as do literal
175filenames and references to items that appear elsewhere in the  reference
176manuals. Arguments are italicized.
177.Lp
178If a command interprets either subcommands or an input grammar, its command
179interface or input grammar is normally described in a
180.Nm USAGE
181section, which follows the
182.Nm OPTIONS
183section.  The
184.Nm DESCRIPTION
185section only
186describes the behavior of the command itself, not that of subcommands.
187.
188.It Nm \&.SH OPTIONS
189.
190The list of options along with a description of how each affects the command's
191operation.
192.
193.It Nm \&.SH RETURN VALUES
194.
195A list of the values the library routine will return to the calling  program
196and the conditions that cause these values to be returned.
197.
198.It Nm \&.SH EXIT STATUS
199.
200A list of the values the utility will return to the calling  program or shell,
201and the conditions that cause these values to be  returned.
202.
203.It Nm \&.SH FILES
204.
205A list of files associated with the command or function.
206.
207.It Nm \&.SH SEE ALSO
208.
209A comma-separated list of related manual pages, followed by references to other
210published materials.
211.
212.It Nm \&.SH DIAGNOSTICS
213.
214A list of diagnostic messages and an explanation of each.
215.
216.It Nm \&.SH BUGS
217.
218A description of limitations, known defects, and possible problems associated
219with the command or function.

223.Sh NOTES
224The
225.Nm
226package should not be used for new documentation.  The
227.Xr mdoc 5 ,
228package is preferred, as it uses semantic markup rather than physical markup.
229.Sh CODE SET INDEPENDENCE
230When processed with
231.Xr mandoc 1 ,
232this package is Code Set Independent. However, when processed with
233legacy tools such as
234.Xr nroff 1
235and
236.Xr troff 1 ,
237the use of multi-byte characters may not be supported.
238.Sh INTERFACE STABILITY
239.Sy Obsolete Committed .
240The
241.Xr mdoc 5
242package should be used instead.
