> The Glasgow Haskell Compiler (GHC) is a state-of-the-art programming suite for
> Haskell. Included is an optimising compiler generating efficient 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. GHC is
> distributed under a BSD-style open source license.
