Erlang programming language

Erlang is a general-purpose concurrent programming language[?] and runtime system. The sequential sub-set of Erlang is a functional language, with strict evaluation[?] and dynamic typing.

Named after A. K. Erlang, it was developed at Ericsson for use in telecommunication hardware. It was designed to support distributed, fault-tolerant, soft-real-time, non-stop applications. Since its release as open source in 1998, it became used by companies world-wide, including Nortel and T-Mobile.

An Open Source implementation is available at http://www.erlang.org. For a licensed and supported version, see http://www.erlang.se. For worldwide training and consulting services see http://www.erlang-consulting.com.

A wiki web devoted to Erlang is at http://www.bluetail.com/wiki/ . A collaborative portal for the Erlang community can be reached at http://www.erlang-projects.org/

Code looks like this:

-module(fact).
-export([fac/1]).

fac(0) -> 1;
fac(N) -> N * fac(N-1).
