This is a function to parse a plain Haskell program. Given a list of files containing the modules of a Haskell program, it returns a list of strongly connected components of modules, and an association list giving information for each module what is in scope and what is exported.

parseHaskellProgram:: 
    [FilePath] -> IO ([[HsModuleR]], [(ModuleName, WorkModuleI HsName Id)])
parseHaskellProgram = parseProgram parse

The function is constructed from the reusable function parseProgram, which takes a module parser as an argument. This allows it to be used for variants of Haskell, e.g. where there are new forms of declarations or expressions. For this to work, there must be instances in some classes for the type of declarations. See the module ParseProgram for details.
