- MAN(7) Minix Programmer's Manual MAN(7)
- NAME
- man - nroff macro package for manual pages
- SYNOPSIS
- nroff -man file ...
- DESCRIPTION
- These macros are used to lay out reference pages for manuals.
- 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 UNIX
- 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).
- FILES
- /usr/lib/tmac/tmac.an For standard Minix nroff.
- /usr/lib/cawf/man.mac For cawf.
- SEE ALSO
- nroff(1), man(1).
- REQUEST SUMMARY
- Request Cause Explanation
- Break?
- .B t no Text t is bold. Quote to imbed blanks.
- .I t no Text t is italic. Quote to imbed blanks.
- .IP x yes Set prevailing indent to 5. Begin
- indented paragraph with hanging tag
- given by first argument. Tag x is
- always placed on a separate line.
- .LP yes Same as .PP.
- .PP yes Begin paragraph. Set prevailing
- indent to 5.
- .RE yes End of relative indent. Set prevailing
- indent to amount of starting .RS.
- .RS yes Start relative indent, move left margin
- in distance 5.
- .SH t yes Subhead. Quote to imbed blanks.
- .SS t yes Subsection. Quote to imbed blanks. No
- indent for t.
- .TH n s c v d yes Begin page named n of chapter s; c is
- the chapter name; d is the date of the
- most recent change; v is version number.
- Sets prevailing indent and tabs to 5.

- EXAMPLE
- The following illustrates some of the requests available with this macro
- package:
- ." this is a comment
- .TH DEMO 1
- .SH NAME
- demo - show how to use -man package
- .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 'e"'
- This is the comment command. " 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)

- CONVENTIONS
- A typical manual page for a command or function is laid out as follows:
- .TH TITLE [1-8]
- The name of the command or function in upper-case,
- which serves as the title of the manual page. This is
- followed by the number of the section in which it
- appears.
- .SH NAME
- name - one-line summary
- The name, or list of names, by which the command is
- called, followed by a dash and then a one-line summary
- of the action performed. All in roman font, this sec-
- tion contains no troff(1) commands or escapes, and no
- macro requests. It is used to generate the whatis(1)
- database.
- .SH SYNOPSIS
- Commands:
- The syntax of the command and its arguments as
- typed on the command line. When in boldface, a
- word must be typed exactly as printed. When in
- italics, a word can be replaced with text that you
- supply. Syntactic symbols appear in roman face:

- MAN(7) Minix Programmer's Manual MAN(7)
- [ ] An argument, when surrounded by brackets is
- optional.
- | Arguments separated by a vertical bar are
- 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.
- Functions:
- If required, the data declaration, or #include
- directive, is shown first, followed by the func-
- tion declaration. Otherwise, the function declara-
- tion is shown.
- .SH DESCRIPTION
- A narrative description of the command or function in
- detail, including how it interacts with files or data,
- and how it handles the standard input, standard output
- and standard error.
- Filenames, and references to commands or functions
- described elswhere in the manual, are italicised. The
- names of options, variables and other literal terms are
- in boldface.
- .SH OPTIONS
- The list of options along with a description of how
- each affects the commands operation.
- .SH ENVIRONMENT
- Environment variables used.
- .SH FILES
- A list of files associated with the command or func-
- tion.
- .SH "SEE ALSO"
- A comma-separated list of related manual pages,
- followed by references to other published materials.
- This section contains no troff(1) escapes or commands,
- and no macro requests.
- .SH DIAGNOSTICS
- A list of diagnostic messages and an explanation of
- each.

- MAN(7) Minix Programmer's Manual MAN(7)
- .SH NOTES
- Any additional notes such as installation-dependent
- functionality.
- .SH BUGS
- A description of limitations, known defects, and possi-
- ble problems associated with the command or function.
- .SH AUTHOR
- The program's author and any pertinent release info.
- .SH VERSION
- The program's current version number and release date.
- BUGS
- Even though cawf(1) has a better chance at formatting a random manual
- page then the standard Minix nroff, it has two annoying bugs in its macro
- set. Both .PP and .IP reset the indentation level to the level set by
- .SH. This means that you can't use them in a piece of text indented by
- .RS. For .IP this is troublesome, you can see why in the unformatted
- source of this text. .PP can simply be replaced by .sp, or better yet,
- by .SP with the following macro defined somewhere in your text:
- .de SP
- .if t .sp 0.4
- .if n .sp
- ..
- This will make .SP use 4/10 of a line if formatted by troff, just like
- .PP.
