+# 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
