# - Package Version should start with a digit
#
# Example (requires daisy tool somewhere in the PATH):
#  build rpm package for el9 like distributions and version 0.0.1 for
#  the last commit in the 'trustca-sync' branch of vorakl/guest-oslogin
#  fork on Github and save results to gs://vorakl-dev-builds/packages/ bucket.
