### PUBLIC

# make_public stage is used to push the current master branch of CAISAR to
# public repositories.

# make_public targets the public repository git.frama-c.com/pub/caisar.
# For that, it uses the 'caisar to caisar-public' deploy key of the public
# repository. The latter is the public part of the key, whereas the private one
# is stored in the environment variable $CAISAR_PUBLIC_SSH_PRIVATE_KEY of the
# private repository.
