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

       /usr/share/tmac/tmac.an

BUGS
