# Example demonstrating how to use the configuration/commandline system
# for configuration.
# Some valid command lines..
# config.py -h --help ; Turn on help
# config.py -no-h --no-help --help=no ; Turn off help
# config.py -qqq -q=3 ; verbosity to 3
# config.py -c /etc/apt/apt.conf ; include that config file]
# config.py -o help=true ; Turn on help by giving a
# ; config file string
# config.py -no-h -- -help ; Turn off help, specify the file '-help'
# -c and -o are standard APT-program options.
# This shows how to use the system for configuration and option control.
# The other varient is for ISC object config files. See configisc.py.
