Vagrant is a tool for building and distributing development environments.

Vagrant::Box#in_use?

Checks if this box is in use according to the given machine
index and returns the entries that appear to be using the box.

The entries returned, if any, are not tested for validity
with {MachineIndex::Entry#valid?}, so the caller should do that
if the caller cares.
