%description
GHC is a state-of-the-art programming suite for Haskell, a purely
functional programming language.  It includes an optimizing compiler
generating good code for a variety of platforms, together with an
interactive system for convenient, quick development.  The
distribution includes space and time profiling facilities, a large
collection of libraries, and support for various language
extensions, including concurrency, exceptions, and foreign language
interfaces (C, C++, etc).
