[GRASS-dev] Using current grass gui.tcl in python programs.

[Michael Barton]

Thanks Cedric.

Good to see you back.

Doesn't Tkinter require TclTk to be installed? If so, is there an advantage
to having gui.tcl run under Python/Tkinter vs. Wish as it does now? That is,
the wxPython prototype I'm working on can launch a GRASS command and it's
TclTk gui. Of course this means I'm running part of the UI under TclTk and
part under wxPython at the moment. Does Tkinter change this?
