# Author Name: Matt McKinnon

# Date: 7th June 2016

# Description: For use on Debian Based Systems
|
|
# 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.
