GROTTY(1)                                               GROTTY(1)

NAME
       grotty - groff driver for typewriter-like devices

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

DESCRIPTION
       grotty  translates  the  output  of  GNU troff into a form
       suitable for  typewriter-like  devices.   Normally  grotty
       should  invoked  by using the groff command with a -Tascii
       or -Tlatin1 option.  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 output.

       Normally  grotty  prints  a  bold  character  c  using the
       sequence `c BACKSPACE c' and a italic character c  by  the
       sequence  `_  BACKSPACE  c'.   These sequences can be dis-
       played 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 fil-
       ter 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 character.  This code can
       also be used in the \N escape sequence in troff.

OPTIONS
       -Fdir  Search  the  directory  dir/devname  for  font  and
              device  description  files; name is the name of the
              device, usually ascii or latin1.

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

       -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.

       -b     Suppress  the  use of overstriking for bold charac-
              ters.

       -u     Suppress the use of underlining for italic  charac-
              ters.

       -B     Use only overstriking for bold-italic characters.

       -U     Use only underlining for bold-italic characters.

       -o     Suppress  overstriking  (other  than  for  bold  or
              underlined characters).

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

       -v     Print the version number.

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 posi-
       tion of 0) cannot be printed.
