How to get it

The easy way is to go to the web page, which should be self-explanatory:

We supply binary builds in the native package format for many
platforms, and the source distribution is available from the same

Packages will appear as they are built - if the package for your
system isn't available yet, please try again later.


Haskell is a standard lazy functional programming language; the
current language version is Haskell 98, agreed in December 1998 and
revised December 2002.

GHC is a state-of-the-art programming suite for Haskell.  Included is
an optimising 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, whatever).  GHC is distributed under a
BSD-style open source license.

A wide variety of Haskell related resources (tutorials, libraries,
specifications, documentation, compilers, interpreters, references,
contact information, links to research groups) are available from the
Haskell home page (see below).
