# See http://www.kali.org/new/kali-linux-metapackages/ for meta packages you can
# use. You can also install packages, using just the package name, but keep in
# mind that not all packages work on ARM! If you specify one of those, the
# script will throw an error, but will still continue on, and create an unusable
# image, keep that in mind.
