# origins are the repositories to automatically upgrade included packages
# blacklist is a list of packages to not automatically upgrade
# update is how often to run "apt-get update" in days
# download is how often to run "apt-get upgrade --download-only" in days
# upgrade is how often to upgrade packages included in the origins list in days
# autoclean is how often to run "apt-get autoclean" in days
