Thanks I've applied, but some minor comments.

This will need moved to doc/ and converted to our markup format (more on that
later).

We should also add a check for GNU octave in configure.ac and a simple script
that runs octave and outputs a C file with the new coefficients (by default it
should just emit the same coefficients we use today).
