Hmmm... is it significant that libaudiofile is here
and not libsndfile? Should we be considering it as
SoX's primary format lib instead of libsndfile?

Nevertheless, I've been looking at moving my 1st
format into LSF; I've chosen vox as I think it falls
into the category of not majorly used, it's pretty
simple, and it's one I know a lot about.  Inevitably,
it's been slow going at first, but I've now come up
against a few issues that are quite sticky (to me at
least).  Reuben, are you able to give any pointers on
these?

1st: I'm trying to do this:
  play -r 6000 file.vox
but LSF doesn't seem to support individual format
options; it either accepts a full set of format
options or none at all:
  if ((sfinfo->format & SF_FORMAT_TYPEMASK) ==
SF_FORMAT_RAW) {
    if (sf_format_check (sfinfo) == 0)
      return SFE_RAW_BAD_FORMAT ;
  }
  else memset(sfinfo, 0, sizeof (SF_INFO));

2nd: Current SoX warns if -r is not given for a vox
file (that a default rate has been chosen).  Can LSF
provide this (i.e. log messages with a severity)?

3rd: How does one make a debug build with LSF?
(./configure --enable-debug doesn't seem to work).
