MAN(7) Miscellaneous Information Manual MAN(7)NAME
man - macros to typeset manual
SYNOPSIS
nroff -man file ...
troff -man file ...
DESCRIPTION
These macros are used to lay out pages of this manual. A skeleton page may be found in the file /usr/man/man.template.
Any text argument t may be zero to six words. Quotes may be used to include blanks in a `word'. If text is empty, special treatment is
applied to the next input line with text to be printed. In this way .I may be used to italicize a whole line, or .SM may be followed by .B
to make small bold letters.
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.
Type font and size are reset to default values before each paragraph, and after processing font and size setting macros.
These strings are predefined by -man:
*R `(Reg)', trademark symbol in troff.
*S Change to default type size.
FILES
