Vagrant is a tool for building and distributing development environments.

VagrantPlugins::HerokuPush::Config#dir

The base directory with file contents to upload. By default this
is the same directory as the Vagrantfile, but you can specify this
if you have a `src` folder or `bin` folder or some other folder
you want to upload. This directory must be a git repository.
