The codec is LGPL, not GPL. You have a right to read it and do not have to
reverse-engineer it, but do not cut and paste the code or its _structure_
if you want to avoid David's copyright. If you want to do something useful
rather than just a BSD version of LGPL code, make it fixed-point instead of
float.
