description         The Erlang Programming Language
long_description    Erlang is a programming language designed at the        \
                    Ericsson Computer Science Laboratory. Open-source       \
                    Erlang is being released to help encourage the spread   \
                    of Erlang outside Ericsson.                             \
                                                                            \
                    We are releasing free of charge:                        \
                        The entire source code of the current Erlang        \
                        system.                                             \
                        Extensive libraries of code for building robust     \
                        fault-tolerant distributed applications.            \
                        All with documentation.                             \
                                                                            \
                    All the above software has been battle tested in a      \
                    number of Ericsson products, for example the new        \
                    Ericsson ATM switch.
