# This script expect the following environment variables to be set:
# - OSX_DEPLOY_KEY: private SSH key, must be encoded like this before adding it to Travis secrets: https://github.com/travis-ci/travis-ci/issues/7715#issuecomment-433301692
# - OSX_DEPLOY_HOST: string specifying SSH of the following format: ssh-user@ssh-host
# - OSX_DEPLOY_PORT: SSH port, it can't be a part of the host string because scp doesn't accept hosts with ports
# - OSX_DEPLOY_HOST_FINGERPRINT: fingerprint of the host, can be obtained by using ssh-keygen -F [host]:port & putting it in double quotes when adding to Travis secrets
