DIR points to a directory on a filesystem. When you want to combine
multiple drives into a single large system, pass one directory per
filesystem separated by space. You may also use a '...' convention
to abbreviate the directory arguments. Remote directories in a
distributed setup are encoded as HTTP(s) URIs.
