# This file is evaluated to provide a console window interface to the
# root Tcl interpreter of an OOMMF application. It calls on a script
# included with the Tk script library to do most of the work, making use
# of Tk interface details which are only semi-public. For this reason,
# there is some risk that future versions of Tk will no longer support
# this script. That is why this script has been isolated in a file of
# its own.
