       nroff - use groff to format documents for TTY devices

       nroff [-CchipStUv] [-dcs] [-Mdir] [-mname] [-nnum] [-olist] [-rcn]

       nroff formats documents written in the roff(7) language for typewriter-
       like devices such as terminal emulators.

       GNU nroff emulates the traditional Unix nroff command using groff(1).
       nroff generates output via grotty(1), groff's TTY output device, which
       needs to know the character encoding scheme used by the terminal.
       Consequently, acceptable arguments to the -T option are ascii, latin1,
       utf8, and cp1047; any others are ignored.  If neither the
       GROFF_TYPESETTER environment variable nor the -T command-line option
       (which overrides the environment variable) specifies a (valid) device,
       nroff consults the locale to select an appropriate output device.  It
       first tries the locale(1) program, then checks several locale-related
       environment variables; see “ENVIRONMENT”, below.  If all of the
       foregoing fail, -Tascii is implied.

       Whitespace is not permitted between an option and its argument.  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 ignores -e,
       -q, and -s (which are not implemented in troff).  The options -p (pic),
       -t (tbl), -S (safer), and -U (unsafe) are passed to groff.  -v and
       --version show version information, while --help displays a usage
       message; all exit afterward.

              specifies the default output device for groff.

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

              are pattern-matched in this order for standard character
              encodings supported by groff in the event no -T option is given
              and GROFF_TYPESETTER is unset.

       Character definitions in the file /usr/share/groff/1.22.4/tmac/
       tty-char.tmac are loaded to replace unrepresentable glyphs.
