# Note that we don't use GNU tar's '-z' option. One reason (but
# not the only reason) is that some versions of tar (e.g., OSF1)
# interpret '-z' differently.
#
# The -o option of GNU tar used to exclude empty directories. This
# behavior was fixed in tar 1.12 (released on 1997-04-25). But older
# versions of tar are still used (for instance NetBSD 1.6.1 ships
# with tar 1.11.2). We do not do anything specific w.r.t. this
# incompatibility since packages where empty directories need to be
# present in the archive are really unusual.
# ----------------------------------------------------------------------
# TODO: this definition-oriented interface is almost good enough to offer
# as a public API allowing the user to define and use new archive formats.
# However, we must think carefully about possible problems before setting
# the API in stone. So, for the moment, we keep this internal and
# private; there will be time to make it public, once (and if) there's
# any request from the user base.
