     "Erlang is a programming language used to build massively
scalable soft real-time systems with requirements on high
availability.  Some of its uses are in telecoms, banking, e-commerce,
computer telephony and instant messaging.  Erlang's runtime system has
built-in support for concurrency, distribution and fault tolerance.")
