# This is currently (2019-08-15) broken on Azure for GitHub-hosted repos. It
# does, however, work as expected for Azure-hosted repos. As a workaround, we
# have created a repo inside Azure that contains an `azure-pipelines.yml` file
# that just triggers this job.
#
# When the situation is resolved, delete that repo in Azure and uncomment the
# following. In the meantime, this should stay commented so we avoid running
# jobs twice when Azure fixes this issue.
