I don't know whether I would want to trust sndcompress for archiving my
.snd files.  I just ran a quick test to see whether I would get back the
same size file if I compressed and then uncompressed a .snd file.  As
you can see, they are not the same size which makes me suspicious.  

Can anyone explain why this happened?  Can anyone confirm this?
I will check to see whether the header could have changed in size.
