# This file is specified in Vagrantfile and is loaded by Vagrant as the primary
# provisioning script whenever the commands `vagrant up`, `vagrant provision`,
# or `vagrant reload` are used. It provides all of the default packages and
# configurations included with Varying Vagrant Vagrants.

# By storing the date now, we can calculate the duration of provisioning at the
# end of this script.

# PACKAGE INSTALLATION
#
# Build a bash array to pass all of the packages we want to install to a single
# apt-get command. This avoids doing all the leg work each time a package is
# set to install. It also allows us to easily comment out or add single
# packages.
