# This ID_RSA_PRIV dance is to make things work on dockerhub

# This is set on the docker build configuration, and forwarded through to this
# script by hooks/build. It only grants read-only access to the repository that
# will be checked out in this image anyway.
#
# Because the key needs to be all one line in the web interface all the newlines are spaces. And that means I had to manually make all the spaces underscores.
# Undo that here.
