# Adds a 'support-firecloud/update' target which will update the support-firecloud git submodule
# to the latest version (semver tag), while also showing the git commits that the update will introduce.
#
# Commits that have the word 'break' will be colour highlighted,
# so the developer can take corrective actions when needed.
