# ZFS_AC_META: Read metadata from the META file. When building from a
# git repository the ZFS_META_RELEASE field will be overwritten if there
# is an annotated tag matching the form ZFS_META_NAME-ZFS_META_VERSION-*.
# This allows for working builds to be uniquely identified using the git
# commit hash.
