Yup, you have to explicitly ask for the documentation. Go to ghc/docs/set, and type 'make set'. The full documentation (combined Users' Guide and Library reference) will end up in set/ after a while.

That does not work. make answers make: *** No rule to make target `set'. Any ideas? Do I have to take special actions when configuring?

oops, sorry I meant 'make html'. You can also do 'make dvi', 'make ps', 'make pdf' etc. Cheers, Simon
