-# Put all the Blimp related files in /blimp so they are kept separate from
-# the OS files. Using '.' instead of '*' ensures directory structure is
-# maintained since ADD only copies the contents of directories. This is done by
-# first adding the files to directory under /tmp/blimp and then copying it to
-# target /blimp location to workaround Docker permission bug
-# (https://github.com/docker/docker/issues/7511 and
-# https://github.com/docker/docker/issues/1295).
