# On Ttk (Tile) extension, 'style' command has imcompatible changes
# depend on the version of the extention. It requires modifying the
# Tcl/Tk scripts to define local styles. The rule for modification
# is a simple one. But, if users want to keep compatibility between
# versions of the extension, they will have to contrive to do that.
# It may be troublesome, especially for Ruby/Tk users.
# This method may help such work. This method make some definitions
# on the Tcl/Tk interpreter to work with different version of style
# command format. Please give attention to use this method. It may
# conflict with some definitions on Tcl/Tk scripts.
