# Usage: ./Install [package names]
#   If no package names are specified then all currently
#   supported packages will be installed
#
# Versions of apt prior to 1.1 do not support install by Debian filename
# You should probably be running a more recent version of apt
# On these early versions, install with the following:
#
# sudo dpkg -i "${PKG}"
# sudo apt-get install -f
