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/local/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.
