+# A ScrolledText widget feels like a text widget but also has a
+# vertical scroll bar on its right. (Later, options may be added to
+# add a horizontal bar as well, to make the bars disappear
+# automatically when not needed, to move them to the other side of the
+# window, etc.)
+#
+# Configuration options are passed to the Text widget.
+# A Frame widget is inserted between the master and the text, to hold
+# the Scrollbar widget.
+# Most methods calls are inherited from the Text widget; Pack methods
+# are redirected to the Frame widget however.
