Have a look at mtree(8). Here's the output of running it on a test
hierarchy:
giorgos@gothmog[13:17]/tmp/alpha$ mtree -c > /tmp/spec.alpha
giorgos@gothmog[13:17]/tmp/alpha$ cd ..
giorgos@gothmog[13:17]/tmp$ mkdir beta
giorgos@gothmog[13:17]/tmp$ cd beta
giorgos@gothmog[13:17]/tmp/beta$ mtree -eU < /tmp/spec.alpha
