| NAME
| man – macros to typeset manual
SYNOPSIS
| `nroff −man` file ...
`troff −man` file ...
DESCRIPTION
| These macros are used to format pages of this manual.
Except in `.LR` and `.RL` requests, any text argument denoted t in the request summary may be zero to six words. Quotes `"` ... `"` may be used to include blanks in a ‘word’. If 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, `.I` may be used to italicize a line of more than 6 words, or `.SM` followed by `.B` to make small letters in ‘bold’ font.
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 are ens.
The fonts are `R` roman, the main font, preferred for diagnostics `I` italic, preferred for parameters, short names of commands, names of manual pages, and naked function names `B` ‘bold’, actually the constant width font, preferred for examples, file names, declarations, keywords, names of `struct` members, and literals (numbers are rarely literals) `L` also the constant width font. In troff `L`=`B`; in nroff arguments of the macros `.L`, `.LR`, and `.RL` are printed in quotes; preferred only where quotes really help (e.g. lower-case literals and punctuation).
Type font and size are reset to default values before each paragraph, and after processing font- or size-setting macros.
The `−man` macros admit equations and tables in the style of eqn(1) and tbl(1), but do not support arguments on `.EQ` and `.TS` macros.
These strings are predefined by `−man`: `\*R` ‘®’, ‘(Reg)’ in nroff. `\*S` Change to default type size. `\*9` The root directory of the Plan 9 installation.

̆`t="" Secondary subhead. `.TF` s yes Prevailing indent is wide as string s in font `L`; paragraph distance is 0. `.TH` n c x yes Begin page named n of chapter c; x is extra commentary, e.g. ‘local’, for page head. Set prevailing indent and tabs to default. `.TP` i yes
`̆
̆
̆`i=p.i. Set prevailing indent to i. Restore default indent if i=0. Begin indented paragraph with hanging tag given by next text line. If tag doesn’t fit, place it on separate line. `.1C` yes Equalize columns and return to 1-column output `.2C` yes Start 2-column nofill output
* n.t.l. = next text line; p.i. = prevailing indent BUGS
| There’s no way to fool troff into handling literal double quote marks `"` in font-alternation macros, such as `.BI`.
There is no direct way to suppress column widows in 2-column output; the column lengths may be adjusted by inserting `.sp` requests before the closing `.1C`.
