[Yhc] Bytecode module interface

Hello all, I'm interested in doing some YHC bytecode manipulation, and I'd like to be able to read a bytecode module using Haskell. In the online Haddock docs, there's a lovely-looking module named 'Module' which contains readModule :: String -> Module http://www-users.cs.york.ac.uk/~ndm/yhc/docs/Module.html However, 'Module' doesnt appear in the 'yhc' or 'yhc-devel' repositories. Does this code exist somewhere else? How can I get at it? Thanks Rob Dockins
