# default.py

# The default script run by the "Python" application in Series 60 Python
# environment. Offers menu options for running scripts that are found in
# application's directory, or in the \my -directory below it (this is
# where the application manager copies the plain Python scripts sent to
# device's inbox), as well as for launching interactive Python console.
