NAME

   nroff - emulate nroff command with groff

SYNOPSIS

   nroff [-CchipStUvwW] [-dcs] [-Mdir] [-mname] [-nnum] [-olist] [-rcn]
         [-Tname] [file ...]
   nroff --help
   nroff -v | --version

DESCRIPTION

   The nroff script emulates the nroff command using groff.   Only  ascii,
   latin1,  utf8,  and  cp1047 are devices accepted by nroff to select the
   output encoding emitted by  grotty,  groff's  TTY  output  device.   If
   neither  the  GROFF_TYPESETTER  environment variable nor the -T command
   line option (which overrides  the  environment  variable)  specifies  a
   (valid)  device,  nroff  checks  the current locale to select a default
   output device.  It first tries the locale program, then the environment
   variables  LC_ALL,  LC_CTYPE,  and  LANG,  and  finally the LESSCHARSET
   environment variable.

   The -h and -c options are equivalent to grotty's options -h (using tabs
   in  the  output)  and  -c  (using  the old output scheme instead of SGR
   escape sequences).  The -d, -C, -i, -M, -m, -n,  -o,  -r,  -w,  and  -W
   options  have  the  effect  described  in troff(1).  In addition, nroff
   silently ignores the options -e, -q, and -s (which are not  implemented
   in troff).  Options -p (pic), -t (tbl), -S (safer), and -U (unsafe) are
   passed to groff.  -v and --version  show  the  version  number,  --help
   prints a help message.

ENVIRONMENT

   GROFF_TYPESETTER
          The  default  device for groff.  If not set (which is the normal
          case), it defaults to 'ps'.

   GROFF_BIN_PATH
          A colon separated list of directories in which to search for the
          groff executable before searching in PATH.  If unset, '/usr/bin'
          is used.

NOTES

   This shell script is basically intended for use  with  man(1).   nroff-
   style character definitions (in the file tty-char.tmac) are also loaded
   to emulate unrepresentable glyphs.
