I've send a message to admin-info@tpc.org and never got an answer. (on
http://www.tpc.org/trademarks/ they list admin@tpc.org as the right
address, but sending a message to admin@ redirects to admin-info@.)

My code doesn't contain any TPC data or code. Its a Java re-implementation
of the C data generator. The only thing it does is using the name "TPC". It
also tries to generate the same data as the official generator, but we
don't claim that.
