# Title:       Vagrantfile
# Description: Bootstrap development environment with Vagrant, Virtualbox and
#              Ansible. All configuration is done through ./vagrant.yml file.
#              DO NOT EDIT Vagrantfile unless you really-really need to do so.
#              Instead edit ./vagrant.yml and all the changes will be fetched
#              by Vagrant on a next provision or up.
# Developer:   ddnomad
# Version:     1.0.2
