# Usage:
# ./rename-tarball original-name.tar.gz new-name.tar.gz
#
# The generated new-name.tar.gz will always have a single main
# directory (named new-name to match the tarball name) in the archive.
# If the original tarball had multiple files in the main directory of
# the archive, all those files will be moved to under the new main
# directory.
