This directory contains winGRASS (GPL).
This version does not require a Xserver on MS-Windows.

You can directly open a GRASS monitor like this:

 d.mon start=x0
 d.mon sel=x0

Enjoy.

Status: 7/2003: The "tcltkgrass" and "nviz" are not working in
  winGRASS/generic (but in wingrass/Xserver). Comments:

The Active State tcl/tk will not get you any further. The problems are

- the cygwin wish does not understand the cygwin paths. Besides that
  there are other problems, e. g. hardcoded xterm references everywhere,
  /dev/null, piping not fully working with cygwin.

- the Active State tcl/tk does not know anything about cygwin, paths do
  not work, etc. Would require a full rewrite of tcltkgrass to get it
  working.

- alternate solution: Using Xserver on Windows:
  my "xtcltk" distribution works quite well with the StarNet XWin
  Server, its a bit slow. Also the XFree86 for cygwin works satisfactorily.

The best route to follow would be a cygwin wish shell which understands the
cygwin paths and adaption/conditionalization of some windows-only things.
Its IMHO very weird that the cygwin wish does not understand the cygwin
paths.

So: send this request to the cygwin developers!
