Richard, could you pleaes remove the copyright notices from
the file
and instead add a reference and/or explanation of where and how
you obtained the data used in the codec.

I'll fix the gencodec.py and remove the copyright notices. I
used
that script to build the initial set of codecs as part of
the CNRI
contracted work -- while the script is (c) CNRI, the output
certainly
isn't anymore.
