    1. Edit src/apt/#{name}/aptfile to specify list of debian packages to install
    2. Provision vagrant and run script to fetch debian packages:

      vagrant up
      vagrant ssh -c '/vagrant/src/apt/fetch_debs.sh #{name}'
      vagrant destroy

    You can search for aptitude debian packages using apt-cache:

      vagrant ssh -c 'apt-cache search #{name} | sort'
