    longDescription = ''
      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.
      This version of Erlang is Basho's version, forked from Ericsson's
      repository.
