# We don't recurse into the library packages with autoreconf anymore, so we
# have to do this manually. To avoid a strict dependency on autoreconf, we
# are careful to call autoreconf only when configure does not exist yet or the
# corresponding configure.ac is newer. This would be dead easy if every shell
# supported the "-nt" option for "test", but this is not the case. The only
# portable solution seems to be via find's "-newer" option or to basically give
# up and replace find with perl:   :-P
#
#   perl -e 'print "configure.ac\n" if -M "configure.ac" < -M "configure"'
