Haskell User's Gofer System
     
         (HUGS) An implementation of {Haskell} derived from
        {Gofer} 2.30b with an interactive development environment much
        like Gofer's.  Almost all of the features of Haskell 1.2 are
        implemented with the exception of the {module} system.  Hugs
        supports Haskell style {type class}es, a full prelude,
        {derived instance}s, defaults, {overloaded} numeric {literal}s
        and {pattern matching}, and {bignum} arithmetic.
