Vagrant is a tool for building and distributing development environments.

Vagrant::Config::Loader#set

Set the configuration data for the given name.

The `name` should be a symbol and must uniquely identify the data
being given.

`data` can either be a path to a Ruby Vagrantfile or a `Proc` directly.
`data` can also be an array of such values.

At this point, no configuration is actually loaded. Note that calling
`set` multiple times with the same name will override any previously
set values. In this way, the last set data for a given name wins.
