+This sample shows how to put multiple objects in the clipboard, one of
+which uses a custom data format.  In this case we use a Python
+dictionary of values for our custom format, and we also put a textual
+representation of the dictionary.  To test this, run two instances of
+this program, enter data in one and click the copy button.  Then click
+the paste button in the other instance.  Also paste into a text editor
+to see the data in the standard text format.
