Changed orig tarballs
---------------------
Sometimes the orig.tar generated by debcargo might change e.g. if you are using
a newer version of debcargo and one of the dependencies relating to generating
the tarball was updated and its behaviour changed - compression settings,
tarball archive ordering, etc. This will cause your upload to get REJECTED by
the Debian FTP archive for having a different orig.tar. In this case, set
REUSE_EXISTING_ORIG_TARBALL=1 when running ``./release.sh``.
