Vagrant is a tool for building and distributing development environments.

Vagrant::Environment#vagrantfile

Represents the default Vagrantfile, or the Vagrantfile that is
in the working directory or a parent of the working directory
of this environment.

The existence of this function is primarily a convenience. There
is nothing stopping you from instantiating your own {Vagrantfile}
and loading machines in any way you see fit. Typical behavior of
Vagrant, however, loads this Vagrantfile.

This Vagrantfile is comprised of two major sources: the Vagrantfile
in the user's home directory as well as the "root" Vagrantfile or
the Vagrantfile in the working directory (or parent).
