Vagrant is a tool for building and distributing development environments.

Vagrant::Action.action_box_add

This is the action that will add a box from a URL. This middleware
sequence is built-in to Vagrant. Plugins can hook into this like any
other middleware sequence. This is particularly useful for provider
plugins, which can hook in to do things like verification of boxes
that are downloaded.
