Vagrant 1.6 introduced the `global-status` command which allows
to get a quick overview of all active Vagrant environments for the
currently logged in user.
Vagrant 1.5 added Vagrant Cloud to share boxes. Some boxes
may be protected, the `login` command allows to access those
protected boxes from Vagrant Cloud.
Vagrant 1.6 introduces a couple new commands, including the `version` command.
The `version` command shows the currently installed version information and
also checks for new updates available.
