# dlgappdemo - a demo of a dialog application.
# This is a demonstration of both a custom "application" module,
# and a Python program in a dialog box.
#
# NOTE:  You CAN NOT import this module from either PythonWin or Python.
# This module must be specified on the commandline to PythonWin only.
# eg, PythonWin /app dlgappdemo.py
