# Description: This script will:
# Clean up the local apt repository of retrieved packages (apt-get clean)
# Resync the package index (apt-get update)
# If called with AUTOUPDATE set to yes then updates will be downloaded and applied with no feed back (not recommended)
# If called without AUTOUPDATE then packages are downloaded and an email is sent informing which packages are to be updated.
# And more ;-)
# NOTE: Perl is needed for this script to work.
#
# Make user configuration changes in this section
