+# Tix.py -- Tix widget wrappers, part of PyTix.
+#
+#	- Sudhir Shenoy (sshenoy@gol.com), Dec. 1995.
+#	  based on an idea (and a little code !!) of Jean-Marc Lugrin
+#						     (lugrin@ms.com)
+#
+# NOTE: In order to minimize changes to Tkinter.py, some of the code here
+#	(TixWidget.__init__) has been taken from Tkinter (Widget.__init__)
+#	and will break if there are major changes in Tkinter.
+#
+# The Tix widgets are represented by a class hierarchy in python with proper
+# inheritance of base classes.
+#
+# As a result after creating a 'w = StdButtonBox', I can write
+#		w.ok['text'] = 'Who Cares'
+#    or		w.ok['bg'] = w['bg']
+# or even	w.ok.invoke()
+# etc.
+#
+# Compare the demo tixwidgets.py to the original Tcl program and you will
+# appreciate the advantages.
