# A sample context menu handler.
# Adds a 'Hello from Python' menu entry to .py files.  When clicked, a
# simple message box is displayed.
#
# To demostrate:
# * Execute this script to register the context menu.
# * Open Windows Explorer, and browse to a directory with a .py file.
# * Right-Click on a .py file - locate and click on 'Hello from Python' on
#   the context menu.
