NAME
       nroff - emulate nroff command with groff

SYNOPSIS
       nroff [ -CchipStUv ] [ -dcs ] [ -Mdir ] [ -mname ] [ -nnum ] [ -olist ] [ -rcn ] [ -Tname ] [ file ... ]

DESCRIPTION
       The  nroff  script  emulates  the  nroff  command using groff.  Only ascii, latin1, koi8-r, utf8, and cp1047 are valid arguments for the -T
       option, selecting the output encoding emitted by grotty, groff's TTY output device.  If an invalid or no -T option is given,  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, and -r 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 shows the version number.

ENVIRONMENT
       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), so warnings are suppressed.  nroff-style character definitions  (in  the  file
       tty-char.tmac) are also loaded to emulate unrepresentable glyphs.
