#This script is based on the original example found here: https://cirrus-ci.org/examples/#release-assets
#modifications made to upload only the single artificate necessary from each freeBSD build of
#openSeaChest. This script should be run after the tar.xz file is created by a successful build
#The other major change is that this script is posix shell compliant instead of requiring bash
