NAME

man − macros for formatting entries in this manual

SYNOPSIS

nroff −man files

troff −man [ −rs1 ] files

DESCRIPTION

These troff(1) macros are used to lay out the format of the entries of this manual. A skeleton entry may be found in the file /usr/man/man0/skeleton.  These macros are used by the man(1) command.

The default page size is 8.5′′×11′′, with a 6.5′′×10′′ text area; the −rs1 option reduces these dimensions to 6′′×9′′ and 4.75′′×8.375′′, respectively; this option (which is not effective in nroff(1)) also reduces the default type size from 10-point to 9-point, and the vertical line spacing from 12-point to 10-point. The −rV2 option may be used to set certain parameters to values appropriate for certain Versatec printers: it sets the line length to 82 characters, the page length to 84 lines, and it inhibits underlining; this option should not be confused with the −Tvp option of the man(1) command, which is available at some UNIX sites. 

Any text argument below may be one to six “words”.  Double quotes ("") may be used to include blanks in a “word”.  If text is empty, the special treatment is applied to the next line that contains text to be printed.  For example, .I may be used to italicize a whole line, or .SM followed by .B to make small bold text.  By default, hyphenation is turned off for nroff, but remains on for troff.

Type font and size are reset to default values before each paragraph and after processing font- and size-setting macros, e.g., .I, .RB, .SM.  Tab stops are neither used nor set by any macro except .DT and .TH. 

Default units for indents in are ens.  When in is omitted, the previous indent is used.  This remembered indent is set to its default value (7.2 ens in troff, 5 ens in nroff−this corresponds to 0.5′′ in the default page size) by .TH, .PP, and .RS, and restored by .RE. 

.TH t s c n Set the title and entry heading; t is the title, s is the section number, c is extra commentary, e.g., “local”, n is new manual name.  Invokes .DT (see below). 

.SH text Place subhead text, e.g., SYNOPSIS, here. 

.SS text Place sub-subhead text, e.g., Options, here. 

.B text Make text bold. 

.I text Make text italic. 

.SM text Make text 1 point smaller than default point size. 

.RI a b Concatenate roman a with italic b, and alternate these two fonts for up to six arguments. Similar macros alternate between any two of roman, italic, and bold:

.IR   .RB   .BR   .IB   .BI

.P Begin a paragraph with normal font, point size, and indent.  .PP is a synonym for .P. 

.HP in Begin paragraph with hanging indent. 

.TP in Begin indented paragraph with hanging tag.  The next line that contains text to be printed is taken as the tag.  If the tag does not fit, it is printed on a separate line. 

.IP t in Same as .TP in with tag t; often used to get an indented paragraph without a tag.

.RS in Increase relative indent (initially zero).  Indent all output an extra in units from the current left margin. 

.RE k Return to the kth relative indent level (initially, k=1; k=0 is equivalent to k=1); if k is omitted, return to the most recent lower indent level. 

.PM m Produces proprietary markings; where m may be P for PRIVATE, N for NOTICE, BP for BELL LABORATORIES PROPRIETARY, or BR for BELL LABORATORIES RESTRICTED. 

.DT Restore default tab settings (every 7.2 ens in troff, 5 ens in nroff).

.PD v Set the interparagraph distance to v vertical spaces.  If v is omitted, set the interparagraph distance to the default value (0.4v in troff, 1v in nroff).

The following strings are defined:

\∗R ® in troff(1), (Reg.)  in nroff(1). troff(1).

\∗S Change to default type size. 

The following number registers are given default values by .TH:

IN Left margin indent relative to subheads (default is 7.2 ens in troff, 5 ens in nroff).

LL Line length including IN. 

PD Current interparagraph distance. 

CAVEATS

In addition to the macros, strings, and number registers mentioned above, there are defined a number of internal macros, strings, and number registers.  Except for names predefined by troff(1) and number registers d, m, and y, all such internal names are of the form XA, where X is one of ), ], and }, and A stands for any alphanumeric character. 

If a manual entry needs to be preprocessed by cw(1), eqn(1) (or neqn), and/or tbl(1), it must begin with a special line (described in man(1)), causing the man command to invoke the appropriate preprocessor(s). 

The programs that prepare the Table of Contents and the Permuted Index for this Manual assume the NAME section of each entry consists of a single line of input that has the following format:

name[, name, name ...] \− explanatory text

The macro package increases the inter-word spaces (to eliminate ambiguity) in the SYNOPSIS section of each entry. 

The macro package itself uses only the roman font (so that one can replace, for example, the bold font by the constant-width font−see cw(1)). Of course, if the input text of an entry contains requests for other fonts (e.g., .I, .RB, \fI), the corresponding fonts must be mounted.

BUGS

If the argument to .TH contains any blanks and is not enclosed by double quotes (""), there will be bird-dropping-like things on the output.
