description The Glorious Glasgow Haskell Compilation System
long_description    \
        The Glasgow Haskell Compiler is a robust,       \
        fully-featured, optimising compiler and interactive \
        environment for Haskell 98, GHC compiles Haskell to \
        either native code or C.  It implements numerous    \
        experimental language extensions to Haskell 98,     \
        for example: concurrency, a foreign language interface, \
        multi-parameter type classes, scoped type variables,    \
        existential and universal quantification, unboxed   \
        types, exceptions, weak pointers, and so on.        \
        GHC comes with a generational garbage collector,    \
        and a space and time profiler.
