NAME
       grotty - groff driver for typewriter-like devices

SYNOPSIS
       grotty [ -bBcdfhioruUv ] [ -Fdir ] [ files... ]

       It is possible to have whitespace between the -F option and its parameter.

DESCRIPTION
       grotty  translates  the	output	of  GNU  troff	into  a form suitable for typewriter-like
       devices.  Normally grotty should be invoked by using the groff  command	with  a  -Tascii,
       -Tlatin1  or  -Tutf8 option on ASCII based systems, and with -Tcp1047 and -Tutf8 on EBCDIC
       based hosts.  If no files are given, grotty will read the standard input.  A filename of -
       will also cause grotty to read the standard input.  Output is written to the standard out-
       put.

       By default, grotty emits SGR escape sequences (from  ISO  6429,	also  called  ANSI  color
       escapes) to change text attributes (bold, italic, colors).  This makes it possible to have
       eight different background and foreground colors; additionally, bold and italic attributes
       can be used at the same time (by using the BI font).

       The  following  colors  are  defined  in tty.tmac: black, white, red, green, blue, yellow,
       magenta, cyan.  Unknown colors are mapped to the default color (which is dependent on  the
       settings  of  the  terminal; in most cases, this is black for the foreground and white for
       the background).

       Use the -c switch to revert to the old behaviour, printing a bold  character  c	with  the
       sequence  `c  BACKSPACE	c' and an italic character c by the sequence `_ BACKSPACE c'.  At
       the same time, color output is disabled.  The same  effect  can	be  achieved  by  setting
       either the GROFF_NO_SGR environment variable or using the `sgr' X command (see below).

       For  SGR support, it is necessary to use the -R option of less(1) to disable the interpre-
       tation of grotty's old output format.  Consequently, all programs which use  less  as  the
       pager  program have to pass this option to it.  For man(1) in particular, either add -R to
       the $PAGER environment variable, e.g.

	      PAGER="/usr/bin/less -R"
	      export PAGER

       or use the -P option of man to set the pager executable and its	options,  or  modify  the
       configuration file of man in a similar fashion.

       grotty's old output format can be displayed on a terminal by piping through ul(1).  Pagers
       such as more(1) or less(1) are also able to display these sequences.  Use either -B or  -U
       when piping into less(1); use -b when piping into more(1).  There is no need to filter the
       output through col(1) since grotty never outputs reverse line feeds.

       The font description file may contain a command

	      internalname n

       where n is a decimal integer.  If the 01 bit in n is set, then the font will be treated as
       an  italic  font;  if the 02 bit is set, then it will be treated as a bold font.  The code
       field in the font description field gives the code which will be used to output the  char-
       acter.  This code can also be used in the \N escape sequence in troff.

OPTIONS
       -b     Suppress the use of overstriking for bold characters.  Ignored if -c isn't used.

       -B     Use only overstriking for bold-italic characters.  Ignored if -c isn't used.

       -c     Use grotty's old output format (see above).  This also disables color output.

       -d     Ignore  all  \D  commands.   Without this grotty will render \D'l...' commands that
	      have at least one zero argument (and so are either horizontal or vertical) using -,
	      |, and + characters.

       -f     Use  form  feeds in the output.  A form feed will be output at the end of each page
	      that has no output on its last line.

       -Fdir  Prepend directory dir/devname to the search path for font  and  device  description
	      files; name is the name of the device, usually ascii, latin1, utf8, or cp1047.

       -h     Use horizontal tabs in the output.  Tabs are assumed to be set every 8 columns.

       -i     Use  escape  sequences  to  set  the italic text attribute instead of the underline
	      attribute for italic fonts (`I' and `BI').  Note	that  most  terminals  (including
	      xterm) don't support this.  Ignored if -c is active.

       -o     Suppress overstriking (other than for bold or underlined characters in case the old
	      output format has been activated with -c).

       -r     Use escape sequences to set the reverse text attribute  instead  of  the	underline
	      attribute for italic fonts (`I' and `BI').  Ignored if -c is active.

       -u     Suppress the use of underlining for italic characters.  Ignored if -c isn't used.

       -U     Use only underlining for bold-italic characters.	Ignored if -c isn't used.

       -v     Print the version number.

USAGE
       grotty understands a single X command produced using the \X escape sequence.

       \X'tty: sgr n'
	      If n is non-zero or missing, enable SGR output (this is the default), otherwise use
	      the old drawing scheme for bold and underline.

ENVIRONMENT
       GROFF_NO_SGR
	      If set, the old drawing scheme for bold and underline (using the backspace  charac-
	      ter) is active.  Colors are disabled.

BUGS
       grotty is intended only for simple documents.

       There is no support for fractional horizontal or vertical motions.

       There is no support for \D commands other than horizontal and vertical lines.

       Characters above the first line (ie with a vertical position of 0) cannot be printed.

       Color  handling	is  different  compared  to  grops(1).	\M doesn't set the fill color for
       closed graphic objects (which grotty doesn't support anyway) but  changes  the  background
       color of the character cell, affecting all subsequent operations.
