-  Upload a source archive and hash at every tagged release.

-  GitHub source archives are generated on demand and not guaranteed to have a
-  constant hash. This is a problem when you try to verify that old releases have
-  not changed. This tool uploads a release archive (that will have the same hash
-  in perpetuity regardless of GitHubs archive cache invalidation) and a text file
-  containing the hash of the archive.
