The
nroff script emulates the
nroff command using groff.
Only
ascii,
ascii8,
latin1,
utf8,
nippon, and
cp1047 are valid arguments for the
-T option.
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
grottys options
-h (using tabs in the output) and
-c (using the old output scheme instead of SGR escape sequences).
The
-C,
-i,
-n,
-m,
-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.
