# Tarballs
# --------
#
# All the necessary tarballs are defined and prepared with this rule.
#
# Note that we want the tarballs to follow the convention of NAME-VERSION
# before the `tar.XX' prefix. For those programs that don't follow this
# convention, but include the name/version in their tarball names with
# another format, we'll do the modification before the download so the
# downloaded file has our desired format.
