       nroff - emulate nroff command with groff


       [-CchipStUvwW] [-dcs] [-Mdir] [-mname] [-nnum] [-olist] [-rcn] [-Tname]
       [file ...]  --help -v | --version


       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/bin’
              is used.


       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.
