GROFF_MAN(7)		Miscellaneous Information Manual	    GROFF_MAN(7)

NAME
     groff_man - groff `man' macros to support generation of man pages

SYNOPSIS
     groff -man [ options... ] [ files... ]
     groff -m man [ options... ] [ files... ]

DESCRIPTION
     The  man macros used to generate man pages with groff were written by James
     Clark.  This document provides a brief summary of the use of each macro  in
     that package.

OPTIONS
     The  man macros understand the following command line options (which define
     various registers).

     -rLL=line-length
	    Set line length.  If this option is not given, the line  length  de-
	    faults to 78n in nroff mode and 6.5i in troff mode.

     -rLT=title-length
	    Set title length.  If this option is not given, the title length de-
	    faults to 78n in nroff mode and 6.5i in troff mode.

     -rcR=1
	    This  option  (the	default  if in nroff mode) will create a single,
	    very long page instead of multiple pages.  Say -rcR=0 to disable it.

     -rC1   If more than one manual page is given on the  command  line,  number
	    the pages continuously, rather than starting each at 1.

     -rD1   Double-sided printing.  Footers for even and odd pages are formatted
	    differently.

     -rPnnn
	    Enumeration of pages will start with nnn rather than with 1.

     -rSxx  Base  document  font  size	is  xx	points (xx can be 10, 11, or 12)
	    rather than 10 points.

     -rXnnn
	    After page nnn, number pages as nnna, nnnb, nnnc, etc.  For example,
	    the option `-rX2' will produce the following page numbers: 1, 2, 2a,
	    2b, 2c, etc.

USAGE
     This section describes the available macros for manual pages.  For  further
     customization,  put  additional macros and requests into the file man.local
     which will be loaded immediately after the man package.

     .TH title section [extra1] [extra2] [extra3]
	    Sets the title of the man page to title and the section to	section,
	    which  must  take on a value between 1 and 8.  The value section may
	    also have a string appended, e.g. `.pm', to indicate a specific sub-
	    section of the man pages.  Both title and section are positioned  at
	    the  left  and right in the header line (with section in parentheses
	    immediately appended to title.  extra1 will  be  positioned  in  the
	    middle of the footer line.	extra2 will be positioned at the left in
	    the footer line (resp. at the left on even pages and at the right on
	    odd  pages	if double-sided printing is active).  extra3 is centered
	    in the header line.

	    For HTML output, headers and footers are completely supressed.

	    Additionally, this macro starts a new page; the new line number is 1
	    again (except if the `-rC1' option is given on the command line)  --
	    this  feature  is intended only for formatting multiple man pages; a
	    single man page should contain exactly one TH macro at the beginning
	    of the file.

     .SH [text for a heading]
	    Sets up an unnumbered section heading  sticking  out  to  the  left.
	    Prints  out  all  the  text  following  SH up to the end of the line
	    (resp. the text in the next input line if there is	no  argument  to
	    SH)  in bold face, one size larger than the base document size.  Ad-
	    ditionally, the left margin for the following text is reset  to  its
	    default value.

     .SS [text for a heading]
	    Sets  up  an  secondary, unnumbered section heading.  Prints out all
	    the text following SS up to the end of the line (resp. the	text  in
	    the  next input line if there is no argument to SS) in bold face, at
	    the same size as the base document	size.	Additionally,  the  left
	    margin for the following text is reset to its default value.

     .TP [nnn]
	    Sets up an indented paragraph with label.  The indentation is set to
	    nnn  if  that argument is supplied (the default unit is `n' if omit-
	    ted), otherwise it is set to the  default  indentation  value.   The
	    first  input  line	of text following this macro is interpreted as a
	    string to be printed flush-left, as it is appropriate for  a  label.
	    It is not interpreted as part of a paragraph, so there is no attempt
	    to	fill  the  first  line with text from the following input lines.
	    Nevertheless, if the label is not as wide as the  indentation,  then
	    the  paragraph starts at the same line (but indented), continuing on
	    the following lines.  If the label is wider  than  the  indentation,
	    then  the  descriptive part of the paragraph begins on the line fol-
	    lowing the label, entirely indented.  Note that neither  font  shape
	    nor  font  size of the label is set to a default value; on the other
	    hand, the rest of the text will have default font settings.  The  TP
	    macro is the macro used for the explanations you are just reading.

     .LP
     .PP
     .P     These macros are mutual aliases.  Any of them causes a line break at
	    the  current position, followed by a vertical space downwards by the
	    amount specified by the PD macro.  The font size and shape are reset
	    to the default value (10pt resp. Roman).  Finally, the current  left
	    margin is restored.

     .IP [designator] [nnn]
	    Sets up an indented paragraph, using designator as a tag to mark its
	    beginning.	 The  indentation is set to nnn if that argument is sup-
	    plied (default unit is `n'), otherwise the default indentation value
	    is used.  Font size and face of the paragraph (but not the	designa-
	    tor)  are  reset  to its default values.  To start an indented para-
	    graph with a particular indentation but without  a	designator,  use
	    `""' (two doublequotes) as the second argument.

	    For  example,  the following paragraphs were all set up with bullets
	    as the designator, using `.IP \(bu 4':

	    *	IP is one of the three macros used in the man package to  format
		lists.

	    *	HP  is	another.   This  macro	produces a paragraph with a left
		hanging indentation.

	    *	TP is another.	This macro produces an unindented label followed
		by an indented paragraph.

     .HP [nnn]
	    Sets up a paragraph with hanging left indentation.	The  indentation
	    is	set  to  nnn if that argument is supplied (default unit is `n'),
	    otherwise the default indentation value is used.  Font size and face
	    are reset to its default values.   The  following  paragraph  illus-
	    trates the effect of this macro with hanging indentation set to 4:

	    This is a paragraph following an invocation of the HP macro.  As you
		can  see,  it produces a paragraph where all lines but the first
		are indented.

     .RS [nnn]
	    This macro moves the left margin to the right by the  value  nnn  if
	    specified  (default  unit is `n'); otherwise the default indentation
	    value is used.  Calls to the RS macro can be nested.

     .RE [nnn]
	    This macro moves the left margin back to level nnn; if  no	argument
	    is	given,	it moves one level back.  The first level (i.e., no call
	    to RS yet) has number 1, and each call to  RS  increases  the  level
	    by 1.

     To summarize, the following macros cause a line break with the insertion of
     vertical space (which amount can be changed with the PD macro): SH, SS, TP,
     LP (PP, P), IP, and HP.  The macros RS and RE also cause a break but no in-
     sertion  of vertical space.  Finally, the macros SH, SS, LP (PP, P), and RS
     reset the indentation to its default value.

MACROS TO SET FONTS
     The standard font is Roman; the default text size is 10 point.

     .SM [text]
	    Causes the text on the same line or the text on the next input  line
	    to	appear in a font that is one point size smaller than the default
	    font.

     .SB [text]
	    Causes the text on the same line or the text on the next input  line
	    to	appear in boldface font, one point size smaller than the default
	    font.

     .BI text
	    Causes text on the same line to appear alternately in bold face  and
	    italic.  The text must be on the same line as the macro call.  Thus

		   .BI this "word and" that

	    would  cause  `this'  and `that' to appear in bold face, while `word
	    and' appears in italics.

     .IB text
	    Causes text to appear alternately in italic and bold face.	The text
	    must be on the same line as the macro call.

     .RI text
	    Causes text on the same line to  appear  alternately  in  roman  and
	    italic.  The text must be on the same line as the macro call.

     .IR text
	    Causes text on the same line to appear alternately in italic and ro-
	    man.  The text must be on the same line as the macro call.

     .BR text
	    Causes  text on the same line to appear alternately in bold face and
	    roman.  The text must be on the same line as the macro call.

     .RB text
	    Causes text on the same line to appear alternately in roman and bold
	    face.  The text must be on the same line as the macro call.

     .B [text]
	    Causes text to appear in bold face.  If no text is	present  on  the
	    line where the macro is called, then the text of the next input line
	    appears in bold face.

     .I [text]
	    Causes  text to appear in italic.  If no text is present on the line
	    where the macro is called, then the text of the next input line  ap-
	    pears in italic.

MISCELLANEOUS
     The  default  indentation is 7.2n for all output devices except for grohtml
     which ignores indentation.

     .DT    Sets tabs every 0.5 inches.  Since this macro is always called  dur-
	    ing  a  TH	request, it makes sense to call it only if the tab posi-
	    tions have been changed.

     .PD [nnn]
	    Adjusts the empty space before a new paragraph (resp. section).  The
	    optional argument gives the amount of space (default units are `v');
	    without parameter, the value is reset to its default  value  (1 line
	    for  tty  devices, 0.4v otherwise).  This affects the macros SH, SS,
	    TP, LP (resp. PP and P), IP, and HP.

     The following strings are defined:

     \*S    Switch back to the default font size.

     \*R    The `registered' sign.

     \*(Tm  The `trademark' sign.

     \*(lq
     \*(rq  Left and right quote.  This is equal to `\(lq' and	`\(rq',  respec-
	    tively.

     If  a  preprocessor  like tbl or eqn is needed, it has become usage to make
     the first line of the man page look like this:

	    .\" word

     Note the single space character after the double quote.  word  consists  of
     letters  for  the needed preprocessors: `e' for eqn, `r' for refer, and `t'
     for tbl.  Modern implementations of the man program read  this  first  line
     and automatically call the right preprocessor(s).

FILES
     man.tmac
     an.tmac
	    These are wrapper files to call andoc.tmac.

     andoc.tmac
	    This  file	checks whether the man macros or the mdoc package should
	    be used.

     an-old.tmac
	    All man macros are contained in this file.

     man.local
	    Local changes and customizations should be put into this file.

SEE ALSO
     Since the man macros consist of groups of groff requests, one can, in prin-
     ciple, supplement the functionality of the man macros with individual groff
     requests where necessary.	A complete list of these requests  is  available
     on the WWW at
