There's some documentation in fptools/ghc/docs/users_guide/utils.sgml
(except it's called hs2c there; I didn't get around to updating the
name).  I can't connect to at the moment so I'm not sure if
the docs there are up to date enough to have this stuff.  Marcin's
QForeign library has plenty of examples too.
