# @BLURB: Helper eclass for gnome.org hosted archives
# @DESCRIPTION:
# Provide a default SRC_URI for tarball hosted on gnome.org mirrors.

# versionator inherit kept for older EAPIs due to ebuilds (potentially) relying on it

# @ECLASS-VARIABLE: GNOME_TARBALL_SUFFIX
# @DESCRIPTION:
# Most projects hosted on gnome.org mirrors provide tarballs as tar.bz2 or
# tar.xz. This eclass defaults to bz2 for EAPI 0, 1, 2, 3 and defaults to xz for
# everything else. This is because the gnome mirrors are moving to only have xz
# tarballs for new releases.
