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 nei-
ther 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 vari-
ables LC_ALL, LC_CTYPE, and LANG, and finally the LESSCHARSET environ-
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/bin'
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.
