Vagrant
	Questions.
		know VMs?
		used VMs?
	: spinning up virtual machines made easy!
	http://www.vagrantup.com/
		installers and packages
		$ apt-get install vagrant
	CLI-based
	We're going to use VirtualBox to host our VMs [the default]
	Get started
		[ host ] $ mkdir my-cool-project && cd my-cool-project
			# make a project directory and change in to it
		[ host ] $ vi cool_script; chmod u+x cool_script
			# some code!
		[ host ]$ vagrant init precise32 http://files.vagrantup.com/precise32.box
			# this will create Vagrantfile and use precise32.box as our base image
		[ host ] $ vagrant up
			# build our VM! (takes ~5 minutes the first time as we download
			# the box over the network)
			# 
			# It'll be faster next time because it will be saved.
		[ host ] $ vagrant ssh
			# Woot! We have a prompt!
		[ vagrant ] $ ls /vagrant/
			# Our files!
		[ vagrant ] $ ./cool_script
			# Yay!
		[ vagrant ] $ touch foobar; exit
			# create a file
		[ host ] $ ls
			# and it's over here too!
	OK, I'm done
		[ host ] $ vagrant suspend
			# save state of memory
	No, I'm *really* done
		[ host ] $ vagrant halt
			# shut down
	Kill it with fire!
		[ host ] $ vagrant destroy
			# VM go bye-bye
	Tabula rasa
		[ host ] $ vagrant up
			# builds it up again
	Wait, back up. Vagrantfile?
		let's take a look
		[ host ] $ vi Vagrantfile
			# explain provisioning
			# http://docs.vagrantup.com/v2/provisioning/shell.html
			#
			# more advanced: configuration management: puppet, chef, cfengine
			#
			# explain networking
			# 
			# enable forwarded port
		[ host ] $ vagrant reload
			# enable changes
