This directory contains files copied as-is from the whirlpool.zip[1]
implementation hosted at
http://www.larc.usp.br/~pbarreto/WhirlpoolPage.html and retrieved on
2014-10-04.

I've only copied the Whirlpool.c[2] and nessie.h[3] files from that
zip file. The Whirlpool.c has had some minor patches (sent upstream)
to fix warnings. That's all in the testing code that isn't actually
used by this module.

The nessie.h file has had a lot of unused code removed (presumably
copied from some generic compatibility library) because e.g. the
ROTL32 macro clashed with hv_func.h in Perl itself. Since it and some
typedefs weren't being used at all I just removed them.
