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 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 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 characters.

          -u   Suppress the use of underlining for italic characters.

          -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 horizontal 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 position
          of 0) cannot be printed.
