tracing Haskell programs

[wvasconc at csd.abdn.ac.uk]

Hi folk

Is there a way to follow the "execution" of a Haskell program? What I mean here
is a way to see which function definition is being used at any moment, and how
the execution control moves around a script file.

If this is a preposterous question, just tell me nicely and I will go away!

Oh, and if this has been discussed before, please tell me where and I will chase
it up.

Thanks!
