.SH DESCRIPTION
The
.B nroff
script emulates the
.B nroff
command using groff.
Only
.BR ascii ,
.BR latin1 ,
.BR utf8 ,
and
.B cp1047
are devices accepted by
.BR nroff
to select the output encoding emitted by
.BR grotty ,
groff's TTY output device.
If neither the
.B GROFF_TYPESETTER
environment variable nor the
.B \-T
command line option (which overrides the environment variable)
specifies a (valid) device,
.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 \-d ,
.BR \-C ,
.BR \-i ,
.BR \-M ,
.BR \-m ,
.BR \-n ,
.BR \-o ,
.BR \-r ,
.BR \-w ,
and
.B \-W
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
and
.B \-\-version
show the version number,
.B \-\-help
prints a help message.
.
.SH ENVIRONMENT
.TP
.SM
.B GROFF_TYPESETTER
The default device for
.BR groff .
If not set (which is the normal case), it defaults to `ps'.
.
.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).
nroff-style character definitions (in the file tty-char.tmac) are also
loaded to emulate unrepresentable glyphs.
