I can include it. The last time I tried, however, there were a few linux
specific functions which kept it from working (see
http://lists.osgeo.org/pipermail/grass-gui/2007-November/000639.html)

This should work from within msys, but won't work when called from cmd.exe
as you cannot easily use shell scripts there. We would need a cmd.exe .bat
file. On the other hand, it might be easier if the wxgrass team could just
rewrite that shell script to python and thus make it portable across all
platforms.

But you can launch wxgrass quite easily by running the command contained
in the wxgrass shell file yourself, i.e. something like:

c:\programme\Python25\python.exe c:\grass\grass-6.3.svn\etc\wx\wxgui.py

However, I currently get the following error:

*****
Traceback (most recent call last):
  File "c:\grass\grass-6.3.svn\etc\wx\wxgui.py", line 53, in <module>
    import gui_modules.utils as utils

<module>
    from win32file import ReadFile, WriteFile
ImportError: No module named win32file

and am too tired to look into it now.
