SUMMARY="The programming language Erlang/OTP"
DESCRIPTION="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."
