-# CI configuration file for CI utilizing cirrus-ci.org
-#
-# For instructions on how to enable the CI integration in a repository and
-# further details, see src/tools/ci/README
-#
-#
-# The actual CI tasks are defined in .cirrus.tasks.yml. To make the compute
-# resources for CI configurable on a repository level, the "final" CI
-# configuration is the combination of:
-#
-# 1) the contents of this file
-#
-# 2) computed environment variables
-#
-#    Used to enable/disable tasks based on the execution environment. See
-#    .cirrus.star: compute_environment_vars()
-#
-# 3) if defined, the contents of the file referenced by the, repository
-#    level, REPO_CI_CONFIG_GIT_URL variable (see
-#    https://cirrus-ci.org/guide/programming-tasks/#fs for the accepted
-#    format)
-#
-#    This allows running tasks in a different execution environment than the
-#    default, e.g. to have sufficient resources for cfbot.
-#
-# 4) .cirrus.tasks.yml
