[Haskell-cafe] Tool for evaluating "GHCi>" lines in a source file

[Steffen Schuldenzucker]

Hi,

some time ago I read of a small tool that extracts lines like "GHCi> 
some_expression" from a source file and appends GHCi's output to them.
Now I can't find it again. Does anyone remember its name?

Thanks. Steffen
