abstract = "In 1944 a computer was commissioned at Bletchley Park
in England. This computer was designed specifically to
find the settings used by German cipher machines to
encrypt messages, which it did very effectively. Before
``Colossus'' the Polish and British military had
developed mechanical machines to aid with cryptography.
All of this work was top secret and only with the
recent release of documents has the true significance
of these machines and the people who created them been
appreciated.",
