+Start a virtualbox image with
+    * all supported interpreters installed
+    * tox installed
+    * this folder mapped read/writable to /vagrant
+    * convenient way to ssh into the box
 
-PYENV_BIN_PATH = "/home/vagrant/.pyenv/bin"
+This should work from Windows, macOS and Linux.
+
+To run tests in the box do:
+    $ cd </path/to/where/this/file/is>
+    $ vagrant up arch
+    $ vagrant ssh arch
+    $ tox
