.SH DESCRIPTION
The
.B nroff
script emulates the
.B nroff
command using groff.
Only 
.BR ascii ,
.BR ascii8 ,
.BR latin1 ,
.BR utf8 ,
.BR nippon ,
and
.B cp1047
are valid arguments for the
.B -T
option.
If an invalid or no
.BR \-T
option is given,
.B nroff
checks the current locale to select a default output device.
It first tries the
.B locale
program, then the environment variables
.BR LC_ALL ,
.BR LC_CTYPE ,
and
.BR LANG ,
and finally the
.B LESSCHARSET
environment variable.
.PP
The
.B \-h
and
.B \-c
options
are equivalent to
.BR grotty 's
options
.B \-h
(using tabs in the output) and
.B \-c
(using the old output scheme instead of SGR escape sequences).
The
.BR \-C ,
.BR \-i ,
.BR \-n ,
.BR \-m ,
.BR \-o ,
and
.B \-r
options have the effect described in
.BR troff (1).
In addition,
.B nroff
silently ignores the options
.BR \-e ,
.BR \-q ,
and
.BR \-s
(which are not implemented in
.BR troff ).
Options 
.B \-p
(pic),
.B \-t
(tbl),
.B \-S
(safer), and
.B \-U
(unsafe) are passed to
.BR groff . 
.B \-v
shows the version number.
.SH ENVIRONMENT
.TP
.SM
.B GROFF_BIN_PATH
A colon separated list of directories in which to search for the
.B groff
executable before searching in PATH.  If unset, `/usr/bin' is used.
.SH NOTES
This shell script is basically intended for use with
.BR man (1),
so warnings are suppressed.
nroff-style character definitions (in the file tty-char.tmac) are also
loaded to emulate unrepresentable glyphs.
