# This is a sample file, and shows the basic framework for using an "Object" based
# document, rather than a "filename" based document.
# This is referenced by the Pythonwin .html documentation.

# In the example below, the OpenObject() method is used instead of OpenDocumentFile,
# and all the core MFC document open functionality is retained.
