Could some kind of self-check be put into oggenc? Flac has
``--verify`` which works by decoding and comparing. Of course this
won't work for Vorbis, because it's lossy. Perhaps each Vorbis
release should come with a reference wave file and the result of
encoding and decoding it with this release. It could then be compared
with a small tolerance to the result of encoding and decoding it on
the target machine. Makes any sense?
