DDE enforces a directory structure where all your projects go into subfolders under the main <projects> folder.
The <projects> folder can be arbitrarily located and named. It is best to put it on the fastest drive you have.
dsh will install the necessary boot2docker-vagrant VM files (Vagrantfile and vagrant.yml) into the <projects> folder.
