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

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, C++, whatever).

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

 System requirements

To compile programs with GHC, you need a machine with 64+MB memory, GNU
and perl. This release is known to work on the following platforms:

  * i386-unknown-{linux,freebsd,mingw32}
  * sparc-sun-solaris2
  * alpha-dec-osf3

Ports to the following platforms should be relatively easy (for a
wunderhacker), but haven't been tested due to lack of time/hardware:

  * hppa1.1-hp-hpux{9,10}
  * i386-unknown-solaris2
  * mips-sgi-irix{5,6}
  * {rs6000,powerpc}-ibm-aix

The builder's guide included in distribution gives a complete
run-down of what ports work; an on-line version can be found at
