Provision a virtual machine for building ChromeOS using Vagrant <http://www.vagrantup.com>. Just download this into a directory, name it ``Vagrantfile`` (if it isn't already), run ``vagrant up`` followed by ``vagrant ssh`` and you'll see two shell scripts there, ready to sync up the ChromeOS source code.

# All Vagrant configuration is done here. The most common configuration
# options are documented and commented below. For a complete reference,

# Create a forwarded port mapping which allows access to a specific port
# within the machine from a port on the host machine. In the example below,
# accessing "localhost:8080" will access port 80 on the guest machine.
# config.vm.network :forwarded_port, guest: 80, host: 8080
# Create a private network, which allows host-only access to the machine
# using a specific IP.
# config.vm.network :private_network, ip: "192.168.33.10"
# Create a public network, which generally matched to bridged network.
# Bridged networks make the machine appear as another physical device on
# your network.

# Share an additional folder to the guest VM. The first argument is

# argument is a set of non-required options.

vb.customize ["modifyvm", :id, "--memory", "8192", "--cpus", "4"]
