 xmcd can also be compiled, but there's a byte ordering problem so it
doesn't work correctly, since it assumes a little-endian architecture
when compiling for FreeBSD (last I looked it didn't explicitly support
NetBSD). xmcd also requires Motif, but I've heard it works usably with
lesstif.

 The current kernel audio cd interface with all its bitfields seems
quite evil. Neverthless, there's a small program written by Allen (I
think) called cdplay which can play audio cds. I've put it on
notcom.org:/pub/cdplay.tar.gz since I don't know where else it can be found.
