# Creates the documentation website and pushes it to the branch
# 'gh-pages' in order to be published.
#
# It is a fallback, when `sbt publish-website` is not working due to
# too large payloads (as it seems) that prohibit uploading through
# githubs http api. Therefore this script uses git (over ssh).
