Bastiaan Heeren is largely responsible for the programming, both of the Top library
and large parts of the Helium
compiler which uses it. Below you can consult the
code documentation and download the sources from the SVN server. The entire library
is written in Haskell
. Downloads of the Helium system
that includes the Top library can be obtained from the Helium website.
We have also cabalized Top, so it can now be obtained from Hackage
