Presubmit tests can be controlled by single-line annotations in the pull
request description. These annotations will be re-examined for each run.
Here is an example of their use:

# Build tests with other unsubmitted packages.
build-group=https://github.com/JCSDA-internal/oops/pull/2284
build-group=https://github.com/JCSDA-internal/saber/pull/651

# Disable the build-cache for tests.
jedi-ci-build-cache=skip

Each configuration setting must be on a single line, but order and
position does not matter.

# Enable tests for your draft PR (disabled by default).
run-ci-on-draft=true

# Use a specific compiler instead of selecting one at random.
# Must be "gcc", "gcc11", or "intel"
jedi-ci-test-select=gcc

# Select the jedi-bundle branch used for building. Using this option
# disables the build cache.
jedi-ci-bundle-branch=feature/my-bundle-change
