[Haskell-cafe] Haskell Report??

Hello, I am trying to use a Haskell shell (Hsh.hs). I am a little frustrated. There are two modules that are imported: import LibPosix import LibSystem I am running WinHugs (Windows) and hugs/ghci can't find LibSystem. I am confused about 1) what are currently standard libraries, etc. in Haskell, 2) what is deprecated and 3) what are "home grown tomatoes" ;^) How current and definitive is the Haskell Report? Kind regards, Bill Halchin
