You're right it's undocumented. I'll fix that.
Is nhc98 fully compliant with the H98 layout rule? There are some good
tests in testsuite/tests/ghc-regress/parser, BTW. I can't build nhc98

ghc-6.2.2: unknown package name: exts
make: Leaving directory `/home/simonmar/tmp/nhc98-1.16/src/hmake'
make: *** [targets/ix86-Linux/hmake-ghc] Error 2
