[Haskell-cafe] Command line utility that shrinks/simplifies functions applications ?

Hi All! Haskell newbie here with a very simple question because google and hoogle are of no help. On the IRC channel #haskell (which I cannot access now from work) I saw somebody using a tool which automatically simplifies expressions,composition of multiple functions to the bare minimum. It was a query to lambdabot I think. Is that tool/library also standalone ? What's its name ? Where can I find it ? That really rocked ... Thanks, Nick
