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