Vagrant is a tool for building and distributing development environments.

Vagrant.require_version

This allows a Vagrantfile to specify the version of Vagrant that is
required. You can specify a list of requirements which will all be checked
against the running Vagrant version.

This should be specified at the _top_ of any Vagrantfile.

Examples are shown below:

  Vagrant.require_version(">= 1.3.5")
  Vagrant.require_version(">= 1.3.5", "< 1.4.0")
  Vagrant.require_version("~> 1.3.5")
