"""
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.
