+
+A container image for canonical-naming and uploading of
+libpod and remote-client archives.  Only intended to ever
+be used by CI/CD, and depends heavily on an embedded
+`release.txt` file produced by `make`.

+Build  script: [../cirrus/build_release.sh](../cirrus/build_release.sh)
+Upload script: [../cirrus/upload_release_archive.sh](../cirrus/upload_release_archive.sh)
